Technical Field

Background

Currently, in industrial production of, for example, glass substrates, electrode bricks such as residual charges are directly pushed by manpower, which has problems of low working efficiency and potential safety hazards. Specifically, in the glass substrate industry, a plurality of large-sized electrode bricks are arranged on two sides of a kiln, glass frit is used as a conductor, and the glass frit is melted into glass liquid after being electrified. The electrode brick is corroded in the long-term contact with the molten glass, and therefore, the electrode brick pushing operation is required to be performed regularly. Four corners of the electrode brick positioned outside the kiln are propped against four to-be-propelled objects such as ejector rods respectively, and the ejector rods are rotated by tens of workers by using ratchet wrenches, so that the electrode brick is propelled towards the inside of the kiln. Because the electrode bricks are wrapped by glass liquid at one side in the furnace, larger resistance is generated, the working temperature close to the furnace body of the kiln is high, the propelling speed of a plurality of electrode bricks is slower, the glass is possibly solidified in the propelling process, the propelling resistance is further increased, and the propelling efficiency is low. In addition, operators need to work on the periphery of the kiln wall at high temperature, and high charges possibly remain on the electrode bricks, so that the manual operation environment is severe, and safety accidents are easy to generate.

Wherein "inner and outer", e.g. inner ring gear, outer ring surface, referred to herein as ring element, are defined in radial direction with respect to the centre of the ring element.

As shown in fig. 1 to 5, the present disclosure provides an adjustment structure 4, a fixing device for a telescopic member using the adjustment structure 4, a propulsion device using the fixing device, and a propulsion system using the propulsion device. Wherein in an exemplary embodiment provided by the present disclosure, the telescopic member is disposed on the fixing device to form the propelling device, in another exemplary embodiment provided by the present disclosure, the propelling device may further comprise a to-be-propelled object 5, and a support structure 6 supporting the to-be-propelled object 5, and the support structure 6 and the positioning structure 3 cooperate to align the telescopic direction of the telescopic member 1 and the to-be-propelled object 5. The various technical schemes provided in the disclosure can be applied to the technical field of glass substrate production, for example, the to-be-pushed object 5 can be a push rod structure on an electrode brick propped against the outside of the kiln, so that the electrode brick is pushed to move towards the inner side of the kiln by the pushing device. Besides the glass substrate field, the various technical schemes disclosed by the invention can be widely applied to other fields needing propulsion, in particular to the technical fields requiring the telescopic direction of the telescopic piece to be aligned with the to-be-propelled object 5 in a rod-shaped structure.

The specific construction and operation of the fixing device for the telescopic element will be described in detail first.

As shown in fig. 1 to 3, the present disclosure provides a fixing device for a telescopic member, which may include a support bracket 2 for supporting the telescopic member 1, and a positioning structure 3 and an adjusting structure 4 provided at opposite ends of the support bracket 2 in a length direction, the support bracket 2 further serving to define a telescopic direction of the telescopic member 1 to be parallel to the length direction of the support bracket 2, the telescopic member 1 being located between the positioning structure 3 and the adjusting structure 4 in the length direction of the support bracket 2 such that the adjusting structure 4 adjusts a position of the telescopic member 1 in the length direction of the support bracket 2 by applying a force to the telescopic member 1, the positioning structure 3 serving to align the telescopic direction of the telescopic member 1 with a to-be-pushed object 5.

Therefore, as long as the telescopic member 1 is placed on the support bracket 2 of the fixing device, the telescopic member 1 can realize the alignment with the to-be-propelled object 5 in the telescopic direction through the positioning structure 3, thereby ensuring that the telescopic member 1 can rapidly and effectively push the to-be-propelled object 5 and improving the working efficiency. In addition, the adjusting structure 4 can adjust the position of the telescopic member 1 in the length direction of the support bracket 2, in other words, the initial contact position of the telescopic member 1 and the to-be-propelled object 5 can be adjusted through the adjusting structure 4, so that the to-be-propelled object 5 with larger propulsion requirement can be suitable under the condition that the maximum telescopic amount of the telescopic member 1 is unchanged. In addition, when the telescopic piece arranged on the fixing device is used for pushing the ejector rod structure on the electrode brick outside the kiln for producing the glass substrate, the electrode brick pushing efficiency is improved, manual operation can be replaced, a large amount of manpower is saved, workers are prevented from working at high temperature close to the periphery of the kiln wall, and personal safety is guaranteed.

The telescopic element 1 can be, for example, a hydraulic cylinder, among other things, since the hydraulic cylinder can provide a powerful power suitable for application in the propulsion of high loads such as ejector pins against electrode bricks and for facilitating the servo control to achieve a reasonable propulsion force. In other variants, the telescopic element 1 may also be one of an electromagnetic telescopic element, an electric cylinder and a pneumatic cylinder, which variants also fall within the scope of protection of the present disclosure.

In various exemplary embodiments provided by the present disclosure, in order to achieve a rapid alignment of the telescopic member 1 with a rod-like structure, such as a ram structure that abuts against an electrode brick, i.e. when the object 5 to be propelled is formed as a rod-like structure, the positioning structure 3 is used to co-linearly arrange the telescopic direction of the telescopic member 1 and the length direction of the rod-like structure. That is, the central axis of the telescopic rod of the telescopic member 1 and the central axis of the rod-like structure are arranged to overlap. In other modifications, the propellant 5 may be formed as a solid of revolution having an axis, such as a columnar structure or a truncated cone structure.

For the convenience of observing the moving process of the telescopic member 1 to monitor whether it is in a normal working state while reducing the weight of the whole fixing device, as shown in fig. 2 and 3, the support bracket 2 may be formed as a plurality of support rods 20 arranged around the telescopic member 1, and the plurality of support rods 20 are gathered toward the telescopic member 1, the length direction of each support rod 20 is parallel to the telescopic direction of the telescopic member 1, and the positioning structure 3 simultaneously passes through the plurality of support rods 20 and is fixed to the plurality of support rods 20. In other words, the plurality of support bars 20 are covered around the telescopic member 1 centering around the telescopic direction thereof, not only playing a role of supporting the telescopic member 1, but also limiting the telescopic direction of the telescopic member 1 in a specific direction along a length direction parallel to the support bars 20, thereby facilitating alignment of the telescopic member 1 and the objects to be propelled 5 by the positioning structure 3.

In other variants, the support bracket 2 may also be formed as a sleeve structure covering the telescopic member 1, the sleeve structure may include a tubular body sleeved on the telescopic member 1, and a cover disposed on one nozzle of the tubular body, the cover being formed with a threaded hole, at this time, the object 5 to be propelled may be inserted into and contacted with the telescopic member 1 through the other nozzle of the tubular body opposite to the cover, and the adjustment structure 4 may be formed as a T-shaped handle including an operation head portion and a threaded rod portion disposed perpendicular to each other, the threaded rod portion passing through the threaded hole of the cover in threaded engagement therewith and abutting against the telescopic member 1, the length of the threaded rod portion inserted into the tubular body being changed by turning the T-shaped handle, so as to adjust the position of the telescopic member 1 in the length direction of the sleeve structure to accommodate the object 5 to be propelled in various propulsion requirements.

Further, in order to reduce the number of the supporting rods 20 and simplify the assembly process of the supporting frame 2 while ensuring that the supporting rods 20 stably support the telescopic members 1, as shown in fig. 1 to 3, the supporting rods 20 have four supporting rods 20 arranged parallel to each other, and the connecting lines of the four supporting rods 20 enclose a square shape on the same cross section. That is, the four support rods 20 are uniformly distributed around the expansion member 1 centering around the expansion direction thereof, thereby realizing reliable and effective support of the expansion member 1. Of course, in other variants, the number of the support rods 20 may be six or eight, and it is also within the scope of the present disclosure for such variants.

In order to improve the functional integration of the parts and simplify the number of parts of the fixing device, as shown in fig. 1 to 3, the adjusting structure 4 passes through the plurality of support rods 20 simultaneously to stop the telescopic members 1, and the adjusting structure 4 is adjustably fixed on the plurality of support rods 20 in position. That is, the adjusting structure 4 is used for adjusting the positions of the telescopic members 1 in the length direction of the plurality of support rods 20 and stopping the telescopic members 1 at the same time, so as to prevent the telescopic members 1 from falling off from the ends of the support rods 20 opposite to the objects 5 to be propelled after receiving the reaction force of the objects 5 to be propelled. Of course, in other variants, the adjustment structure 4 and the stop for stopping the telescopic element 1 can also be different components.

Further, to facilitate assembly of the fixing device, as shown in fig. 1 to 3, the support rods may be formed as threaded rods, and the adjustment structure and the positioning structure are respectively screwed on each threaded rod through threaded engagement. That is, at least three cases may be included here: 1. the adjusting structure 4 and the positioning structure 3 are respectively provided with a thread structure matched with each threaded rod, and the adjusting structure 4 and the positioning structure 3 are respectively screwed on the threaded rods through the respective thread structures; 2. the adjusting structure 4 and the positioning structure 3 are respectively screwed on the adjusting structure 4 and the positioning structure 3 by means of additional parts such as screw thread structures of nuts and the like so as to realize the fixation of the adjusting structure 4 and the positioning structure 3 on a threaded rod; 3. the adjustment structure 4 and the positioning structure 3 are screwed onto the threaded rod simultaneously by means of the thread structure formed by themselves and additional components such as nuts.

In other variants, the threaded rod may also be formed as a polished rod, in which case the positioning structure 3 may be welded, for example, to the polished rod, while the adjustment structure 4 may comprise the above-mentioned T-shaped handle, and a fixed plate which passes through and is welded to a plurality of polished rods simultaneously, the fixed plate being formed with a threaded hole through which the threaded rod portion of the T-shaped handle passes and abuts against the telescopic member 1, the adjustment of the position of the telescopic member 1 on the polished rod being achieved by rotating the T-shaped handle.

In various exemplary embodiments provided in the present disclosure, in order to facilitate rapid adjustment of the position of the above-described telescopic member 1 waiting for an adjuster on the support bracket 2 constructed of a plurality of threaded rods, as shown in fig. 3 to 5, the adjustment structure 4 may include a plurality of driven gears 40 sleeved on the plurality of threaded rods in one-to-one correspondence, driving parts 41 respectively engaged with the plurality of driven gears 40 to drive the plurality of driven gears 40 to rotate synchronously, and a holder 42 for holding the driving parts 41 respectively engaged with the plurality of driven gears 40, a mounting hole of each driven gear 40 is formed as a threaded hole 400, and the adjustment structure 4 is screwed on each threaded rod through the threaded hole 400 of each driven gear 40. In other words, the number of the threaded rods is the same as the number of the driven gears, one threaded rod is sleeved with one driven gear, and since the above-mentioned plurality of threaded rods are arranged in a loop around the expansion member, the plurality of driven gears are arranged at intervals in the circumferential direction so that the plurality of driven gears 40 can be engaged with the driving part 41 at the same time, and the mounting hole of each driven gear is formed as the threaded hole 400 that can be screw-engaged with the threaded rod. Therefore, only the driving portion 41 needs to be rotated to drive the driven gears 40 to move synchronously along the axial directions of the threaded rods, so that the driven gears 40 synchronously push the object to be regulated to move on the threaded rods, and once the object to be regulated moves to a preset position on the threaded rods, the position of the object to be regulated on the threaded rods can be changed only by rotating the driving portion 41, namely, the adjusting structure 4 can be always locked at the preset position after receiving the acting force applied by the object to be regulated along the axial direction of the threaded rods, such as a telescopic piece, by waiting for the acting force applied by the object to be regulated, namely, the adjusting structure 4 can stop any acting force except the acting force applied by the driving portion 41 by utilizing the self thread structure, thus realizing the axial limiting effect on the object to be regulated, such as the telescopic piece 1, and the structure is simple, and no additional axial locking structure such as a locking nut is required to be arranged, so that the operation is rapid and convenient. In addition, the plurality of threaded rods are matched with the plurality of driven gears with the same quantity, so that the object to be adjusted can be firmly fixed on the plurality of threaded rods.

In the various exemplary embodiments provided in the present disclosure, the number of the driven gears 40 is the same as the number of the threaded rods, and thus, when the threaded rods are uniformly distributed around the telescopic member 1 centering around the telescopic direction thereof, the driven gears 40 correspondingly have four circumferentially equally spaced apart, so that it is possible to stably support the telescopic member 1 waiting for the adjustment object using as few parts as possible.

It should be noted that the adjusting structure 4 may also be used for other objects to be adjusted that need to be adjusted in position on the threaded rod, and is not limited to the telescopic member.

The retainer 42 is used for always keeping the driving portion 41 and the driven gears 40 engaged at the same time after the adjusting structure 4 receives the axial reaction force of the telescopic member 1, so as to prevent the driven gears 40 from being separated from the driving portion 41 in the axial direction under the action of the axial reaction force.

Further, in order to improve the operation convenience when the driving part 41 rotates, as shown in fig. 3 to 5, the driving part 41 is formed as a ring gear, a plurality of driven gears 40 are all positioned at the inner side of the ring gear to be engaged with the ring gear, and an outer ring surface of the ring gear is further formed with an operation part 410 for rotating the ring gear. That is, the ring gear is rotated by operating the operating part 410, thereby driving the plurality of driven gears 40 engaged with the ring gear to move in the axial direction of the threaded rod.

In another modification, the driving portion 41 may be formed as a driving gear surrounded by a plurality of driven gears 40, and an operation handle extending in the axial direction may be provided on the driving gear, and the driving gear may be rotated by operating the operation handle, thereby driving the plurality of driven gears 40 engaged with the driving handle to move in the axial direction of the threaded rod.

Besides the above gear pair transmission mode of meshing gears or meshing gears with gear rings to ensure that a plurality of driven gears synchronously move on the threaded rods, the adjusting structure 4 can also adopt a stop plate with a plurality of avoidance light holes corresponding to the threaded rods one by one to realize the adjustment of the positions of the telescopic members. Specifically, a plurality of threaded rods respectively pass through a plurality of corresponding avoidance light holes on the stop plate, then the stop plate is pushed to the preset position of the threaded rods, and finally the stop plate is respectively fixed on the threaded rods by a plurality of nuts. More specifically, nuts may be provided on both sides of the stop plate, or nuts may be provided only on the side of the stop plate facing away from the telescopic member 1.

Specifically, as shown in fig. 4 and 5, in order to increase friction force when an operator contacts the outer circumferential surface of the ring gear and thus to facilitate rotation of the ring gear, the operating part 410 may be formed as a plurality of operating fins 4100 arranged at equal intervals along the circumferential direction of the outer circumferential surface of the ring gear. Further, in order to protect the hands of the operator, the operator is facilitated to rotate the ring gear, each of the operation fins 4100 extends in an axial direction parallel to the ring gear, and the projection of each of the operation fins 4100 on the end surface of the ring gear is formed in a semicircle. That is, the outer ring surface of the ring gear is provided with a ring of corrugations having peaks and valleys, so that the friction force is conveniently increased, and the outer surface of the operation rib 4100 is a smoothly transitive curved surface, thereby avoiding scratching the hands of an operator, facilitating the operator to hold the ring gear for rotation, and improving the comfort of the operator to hold the ring gear. Of course, in other variants, the cross section of the operation rib 4100 may be formed into other smoothly transitional arc structures, and such variants are also within the scope of the present disclosure.

In another modification, the operation portion 410 may be formed as a rough surface for increasing friction force on the outer ring surface of the ring gear, for example, the rough surface may be formed of a plurality of transverse stripes or diagonal stripes equally spaced circumferentially along the outer ring surface of the ring gear.

Since a plurality of threaded rods are required to support the telescopic member 1, they can be made of heat-resistant stainless steel in order to make them resistant to deformation by force and to adapt to high temperature environments such as the periphery of a kiln.

In addition, in various exemplary embodiments of the present disclosure, in order to make the plurality of driven gears 40 loosely fitted with the threaded rods, so that the driving part can easily stir the plurality of driven gears 40 and make the driven gears have good axial force performance, the thread pitch of each threaded rod is between 2mm and 3mm, and the thickness of the driven gears is between 10mm and 20mm, i.e., the tooth width of the driven gears is between 10mm and 20 mm.

In the present disclosure, the holder 42 may be any bracket structure capable of holding a plurality of driven gears to be engaged with the ring gear, and in one exemplary embodiment provided in the present disclosure, as shown in fig. 4 and 5, the holder 42 may include first and second fixing plates 421 and 422 at opposite end surfaces of the ring gear and the plurality of driven gears 40, respectively, each of the first and second fixing plates 421 and 422 being formed with a light hole 420 through which a plurality of threaded rods pass, i.e., the first and second fixing plates 421 and 422 are formed with a plurality of light holes 420 in one-to-one correspondence with the threaded holes 400 of the plurality of driven gears 40 in an axial direction, so that the threaded rods passing through the mounting holes of the plurality of driven gears 40 pass through the first and second fixing plates. Wherein the first fixing plate 421 is fixed to the second fixing plate 422 to define a working space between the first fixing plate 421 and the second fixing plate 422 for maintaining the ring gear and the plurality of driven gears 40 engaged. Wherein, a suitable gap can be reserved between the first fixing plate 421 and the second fixing plate 422 to avoid interference with rotation of the inner gear ring and the driven gears. In this way, the first fixing plate 421 and the second fixing plate 422 provided by the opposite end surfaces of the plurality of driven gears 40 and the ring gear are fixed as one body, not only can the driven gears 40 be prevented from being separated from the engagement with the ring gear from the axial direction, but also the acting force from the telescopic member 1 can be resisted, the acting force is prevented from directly acting on the plurality of driven gears and the ring gear, and the service lives of the gears and the ring gear are improved.

Further, in order to facilitate replacement and repair of the driven gear 40 between the first and second fixing plates 421 and 422, the first fixing plate 421 is coupled to the second fixing plate 422 by a fastener 424. That is, the first fixing plate 421 is detachably connected to the second fixing plate 422 via the fastener 424, so that the plurality of driven gears 40 located in the working space can be easily replaced and repaired.

Further, in order to make the contact surface of the telescopic member 1 and the adjustment structure 4 be a plane, thereby ensuring that the adjustment structure 4 smoothly and effectively pushes the telescopic member 1 to move on the threaded rod, as shown in fig. 4 and 5, in the length direction of the support bracket 2, a first fixing plate 421 is located between the telescopic member 1 and a second fixing plate 422, a connection protrusion 423 protruding toward the second fixing plate 422 and formed with a threaded blind hole 4230 is provided on the first fixing plate 421, a plurality of driven gears 40 are provided around the connection protrusion 423 and spaced apart from the connection protrusion 423, and a fastening bolt passes through the second fixing plate 422 and is screwed into the threaded blind hole 4230 of the connection protrusion 423. That is, by directly contacting the first fixing plate 421 with the telescopic member 1, the adjusting structure 4 can be facilitated to smoothly push the telescopic member 1 to move, and in addition, the first fixing plate 421 and the second fixing plate 422 are effectively and firmly fixed as a whole via the connection protrusion 423 formed with the screw blind hole 4230.

Having described the specific structure of the support bracket 2 and the adjustment structure 4 of the fixing device provided by the present disclosure, the specific structure of the positioning structure 3 of the fixing device will be described while describing the pushing device.

As described above, in another exemplary embodiment provided in the present disclosure, the propulsion device may include the above-described fixing device for a telescopic member, the telescopic member 1, and the object to be propelled 5, so that the telescopic member 1 can be aligned with the object to be propelled quickly, thereby improving the working efficiency of the telescopic member to propel the object to be propelled, and the propulsion device may further include a support structure supporting the object to be propelled, and the support structure and the positioning structure cooperate to align the telescopic direction of the telescopic member with the object to be propelled.

Further, when the object 5 to be propelled is formed into the above-described rod-like structure, the supporting structure 6 and the positioning structure 3 cooperate so that the telescoping direction of the telescoping member 1 and the length direction of the rod-like structure are aligned. Specifically, as shown in fig. 2 and 3, the positioning structure 3 may include a U-shaped chuck 30 formed by sequentially connecting a first side plate 31, a third side plate 33 and a second side plate 32 to enclose an opening facing away from the telescopic member 1, positioning slots 300 formed on the first side plate 31 and the second side plate 32 with the opening facing downward, respectively, and a avoidance slot 330 formed on the third side plate 33 with the opening facing downward, so that a rod-shaped structure passing through the avoidance slot 330 can be aligned with the telescopic direction of the telescopic member 1, and the third side plate 33 is fixed to the support bracket 2.

Correspondingly, the supporting structure 6 may include a vertical column 61 vertically passing through the rod-shaped structure, and positioning clamping blocks 62 disposed on two opposite sides of the vertical column 61, the u-shaped clamping head 30 is clamped on the vertical column 61, and the positioning clamping groove 300 is clamped on the corresponding positioning clamping block 62.

The column 61 may be formed as a hollow square steel, or may be formed as a square steel structure formed by joining a pair of U-shaped channel steels. Since the rod-shaped structure needs to pass through the through hole on the upright post 61, in order to avoid the through hole being deformed due to the compression of the through hole by the rod-shaped structure subjected to the pushing force, as shown in fig. 1 and 2, reinforcing plates can be respectively arranged on two opposite end surfaces of the through hole of the upright post, so as to improve the local structural strength of the through hole of the upright post.

The positioning block 62 may be screwed or welded to the upright 61, so as to ensure that the fixing device and the supporting structure 6 are arranged perpendicular to each other.

In this way, when the positioning structure 3 of the fixing device is mounted on the supporting structure 6, the U-shaped clamp 30 can be placed towards the upright post 61 from top to bottom, so that the U-shaped clamp 30 is clamped on the upright post 61, and meanwhile, the positioning clamping grooves 300 on the first side plate 31 and the second side plate 32 of the U-shaped clamp 30 are respectively clamped on the corresponding positioning clamping blocks 62, so that the support bracket 2 can be quickly and accurately hung on the supporting structure 6, and the rod-shaped structure penetrating through the upright post 61 can be aligned with the telescopic direction of the telescopic piece 1.

Further, in order to ensure the positioning accuracy between the rod-like structure and the telescopic member 1 while facilitating the processing, the structure of the pushing device is simplified, the first side plate 31 is parallel to the second side plate 32 and perpendicular to the third side plate 33, and the third side plate 33 is perpendicular to the length direction of the support bracket 2, the positioning card slot 300 has a pair of first card slot walls 301 parallel to each other and extending vertically, and a second card slot wall 302 located between the pair of first card slot walls 301, and the second card slot wall 302 and each first card slot wall 301 are perpendicular to each other.

In cooperation, the cross section of the upright 61 may be formed in a rectangular structure, such that three side walls of the upright 61 respectively fit the U-shaped chuck 30, and the positioning fixture 62 is formed as a rectangular fixture fitted on the side walls of the upright 61, and three side surfaces of the rectangular fixture respectively fit the pair of first fixture groove walls 301 and the second fixture groove walls 302. That is, each side plate passing through the U-shaped chuck 30 is clamped and attached to the corresponding side wall of the upright post 61, so that the expansion and contraction direction of the expansion and contraction member 1 is perpendicular to the upright post 61, and then is clamped on the rectangular clamping block through the positioning clamping grooves 300 on the first side plate 31 and the second side plate 32, and finally, the expansion and contraction direction of the expansion and contraction member 1 is ensured to coincide with the length direction of the rod-shaped structure.

In various exemplary embodiments provided by the present disclosure, to accommodate the avoidance of a propellant formed in a rod-like structure, as shown in fig. 2 and 3, the avoidance slot 330 may be formed in an arch-like structure constructed of a semicircular arc section 331 and a straight line section 332 located below the semicircular arc section 331. In this way, the rod-like structure may first enter through the opening of the arch and be accommodated in the semi-circular arc section 331.

Further, in order to secure the reliability of the connection of the positioning structure 3 and the supporting structure 6, as shown in fig. 2 and 3, the positioning structure 3 may further include an auxiliary reinforcing plate 34 parallel to the third side plate 33 and fixed to the support bracket 2, the auxiliary reinforcing plate 34 being located between the telescopic member 1 and the third side plate 33 in the length direction of the support bracket 2, and the auxiliary reinforcing plate 34 having the same structure as the third side plate 33. In other words, the auxiliary reinforcing plate 34 may also include the escape slots 330 formed in an arch structure as described above, and the auxiliary reinforcing plate 34 and the third side plate 33 may each be screwed to the plurality of threaded rods by nuts, for example.

In various exemplary embodiments provided by the present disclosure, to facilitate locking the to-be-propelled object 5 to the support structure 6 after the to-be-propelled object is propelled to a predetermined position, the to-be-propelled object may be formed as a threaded push rod that is screwed to the support structure 6 by a screw-fit. That is, when the threaded push rod is pushed into place, it is screwed onto the support structure 6 by a nut preset to be fitted onto the threaded push rod, specifically, the nut fitted onto the threaded push rod may be screwed onto the side wall of the upright 61 of the support structure 6.

Further, in various exemplary embodiments provided in the present disclosure, in order to increase the contact area between the telescopic member 1 and the screw push rod such that the pushing force provided by the telescopic member 1 is smoothly and uniformly transferred to the screw push rod, as shown in fig. 1 to 3, the pushing device may further include a circular push plate 7 supported via the support bracket 2, the plate surface of the circular push plate 7 is perpendicular to the telescopic direction of the telescopic member 1, and the circular push plate 7 is located between the telescopic member 1 and the positioning structure 3 in the length direction of the support bracket 2 such that the telescopic member 1 pushes the screw push rod via the circular push plate 7. That is, by providing the circular push plate 7, the contact area between the telescopic end of the telescopic member 1 and the threaded push rod is increased, and the smooth and uniform transmission of the power provided by the telescopic member 1 to the threaded push rod is ensured. In other variants, the circular push plate 7 may be replaced by other suitably shaped push plate structures, such as square, hexagonal or octagonal.

The circular push plate 7 can be assembled on the telescopic rod or the threaded push rod of the telescopic member 1 in a threaded manner or in a welded manner, for example, and the circular push plate 7 can be directly limited between the threaded push rod and the telescopic member by the support bracket 2 without being assembled with the telescopic member or the threaded push rod in order to save assembly procedures.

In order to facilitate the screw push rod to safely push the charged body such as electrode bricks provided on a kiln for glass substrate production, etc. with residual charges, as shown in fig. 1 and 2, the screw push rod is used to push the charged body 8 under the pushing of the telescopic member 1, and the end of the screw push rod away from the telescopic member 1 is provided with an insulator 9 for isolating the screw push rod from the charged body 8. That is, the whole propulsion device is insulated from the charging body 8 by the insulator 9 to protect the operator and the propulsion device.

Further, in order to make the threaded push rod smoothly and uniformly push the charged body such as an electrode brick, the pushing device may have four threaded push rods arranged in parallel with each other, the insulators 9 of the four pushing devices are abutted against the charged body 8 via the pushing plate 80 formed substantially in a rectangular shape, and the insulators 9 of the four pushing devices are respectively abutted against and fitted to the four corners of the pushing plate 80. That is, the contact area between the four propelling devices and the charging body 8 is increased by arranging the pushing plate 80, so that the power provided by the propelling devices is smoothly transferred to the charging body. In addition, the threaded push rods of the four propulsion devices respectively abut against the four corners of the push plate 80 via the insulators 9, further ensuring that the total power provided as the four propulsion devices is evenly distributed to the charged body.

The insulator 9 can be made of, for example, a high-temperature-resistant insulating ceramic. In addition, in order to avoid the insulator 9 falling from between the pushing plate 80 and the threaded push rod, a first sinking groove with an opening facing the insulator 9 may be formed on the pushing plate 80, and a second sinking groove with an opening facing the threaded push rod may be formed on the insulator 9, so that by embedding the insulator 9 in the first sinking groove, the threaded push rod is embedded in the second sinking groove, the insulator can be effectively prevented from sliding down, and the pushing efficiency of the pushing device is improved.

Wherein the substantially rectangular push plate may include a gab frame 60 fixed to the ground and disposed in parallel with the push plate 80, a pair of mutually parallel U-shaped handles 600 fixed to the gab frame 60 at one side of the telescopic member 1, and a middle section of each U-shaped handle 600 vertically extends for fixing two screw push rods, respectively. That is, the four propulsion devices share the base formed as the frame in a shape of a Chinese character kou, and only two U-shaped handles 600 are needed to complete the assembly, so that the overall structure of the propulsion device is more compact, the number of parts is reduced, and the cost is reduced. Specifically, the middle section of each U-shaped handle of the support structure 6 may serve as the upright 61 described above, and the U-shaped handle 600 may further include a pair of horizontal sections that are each connected to the mouth-shaped frame 60.

The frame 60 can greatly increase the structural strength of the whole supporting structure 6, so as to enhance the stress performance of the middle section of the U-shaped handle 600, and avoid the middle section from tilting or deforming after being acted by the screw push rod. The box frame 60 may be secured to both the kiln walls and the floor supporting charged bodies such as electrode bricks, and the box frame 60 may be secured only to the floor without any mounting relationship to the kiln walls.

In assembling the propulsion device, the assembly of the adjustment structure 4 may be first performed, specifically, the ring gear and the plurality of driven gears 40 are placed on the first fixing plate 421 such that the plurality of driven gears 40 are all engaged with the ring gear, and then the plurality of threaded rods are respectively threaded through the through holes of the first fixing plate 421 in a one-to-one correspondence manner and screwed into the threaded holes of the plurality of driven gears 40 in a one-to-one correspondence manner, that is, each threaded rod is threaded through one through hole of the first fixing plate 421 and is correspondingly screwed into the threaded hole of the driven gear 40 in axial communication with the through hole, and then the second fixing plate 422 is mounted to the first fixing plate 421 by fastening bolts, thereby achieving the assembly of the adjustment structure 4 and the plurality of threaded rods.

Next, the telescopic member 1 and the circular push plate 7 are sequentially placed in an inner space formed by a plurality of threaded rods, and then the positioning structure 3 is assembled, namely, one ends of the plurality of threaded rods opposite to the adjusting structure 4 respectively pass through holes on the auxiliary reinforcing plate 34 and the third side plate 33, and each threaded rod is respectively screwed on the auxiliary reinforcing plate 34 and the third side plate 33 through two nuts, as shown in fig. 3, the positioning structure 3 can be connected with the adjusting structure 4 into a whole through the plurality of threaded rods, and the telescopic member 1 and the circular push plate 7 are limited in the inner space enclosed by the plurality of threaded rods, the adjusting structure 4 and the positioning structure 3.

The fixing device assembled with the telescopic member is then hung on the supporting structure 6, specifically, firstly, one end of the threaded push rod passes through the upright post 61 and abuts against the insulator 9, the insulator 9 abuts against the corresponding corner of the pushing plate 80, and then the U-shaped clamping head 30 of the positioning structure 3 is clamped on the upright post 61 by the method described above, so that the assembly of the pushing device can be completed. In use, when the telescopic member 1 pushes the threaded push rod to the preset position of the charged body such as an electrode brick, the threaded push rod can be screwed onto the end face of the through hole of the upright post 61 by a nut sleeved on the threaded push rod, and in particular, for convenience of operation, the end face of the through hole can be the end face of the hole near one side of the charged body.

As described above, the telescopic member 1 may be a hydraulic cylinder, and in order to control the pushing force of the hydraulic cylinder according to the pushing state of the electrode bricks, for example, and ensure that the electrode bricks stably advance in a state parallel to the furnace wall of the kiln, as shown in fig. 1, an oil inlet pipe of the hydraulic cylinder is provided with a flow regulating valve for regulating the amount of oil inlet. In particular, the flow regulating valve may be an electric flow regulating valve which may allow electric control or manual control by an operator. For example, the electric flow regulator valve may be a T966Y electric multi-stage throttle regulator valve.

In order to facilitate the real-time monitoring of the pushing force of the telescopic member 1, thereby avoiding damage to electrified bodies such as electrode bricks and the pushing device due to overlarge pushing force of the telescopic member 1, the telescopic member can be further provided with a pressure sensor for detecting the pushing pressure of the telescopic member. Therefore, when the telescopic piece 1 reaches the maximum safety threshold, for example, the glass liquid resistance on the inner side of the electrode brick is too large, so that the telescopic piece 1 cannot continuously push the electrode brick to advance, and the pushing device can be manually or automatically controlled to stop working at the moment, so that the electrode brick and the pushing device are prevented from being damaged.

In order to facilitate automatic control of the propulsion device to propel an electrically charged body, such as an electrode brick, for safe and efficient propulsion operations, as shown in fig. 1, the present disclosure also provides a propulsion system that may include the propulsion device described in detail above, wherein the telescoping member is a hydraulic cylinder; a pressure detection device for detecting a pushing pressure of the hydraulic cylinder; a flow rate adjusting device 100, wherein the flow rate adjusting device 100 is used for adjusting the oil inlet amount of an oil inlet pipeline of the hydraulic cylinder; and a control device 200 connected to the pressure detecting device and the flow rate adjusting device 100, respectively, for controlling the operation of the flow rate adjusting device 100 based on the pressure signal detected by the pressure detecting device.

Specifically, the 100 flow rate adjusting device may be the above-mentioned electric flow rate adjusting valve, the pressure detecting device may be the above-mentioned pressure sensor, and the control device 200 may be a PLC controller provided in the electric cabinet 3.

In order to ensure safe and efficient automatic and smooth pushing of the charged body, e.g. an electrode brick, the control process of the propulsion system is described taking the example of the above-mentioned four propulsion devices pushing four corners of the electrode brick simultaneously.

In general, the four corners of the electrode brick are subjected to the same resistance to the molten glass, and at this time, the control device 200 controls the flow adjusting device of each propulsion device to have the same oil feeding amount, for example, controls the opening of the electric flow adjusting valve to have the same size, so as to ensure that the four propulsion devices apply uniform thrust to the four corners of the electrode brick, so that the propulsion speeds of the four corners of the electrode brick are the same, that is, the electrode brick can move towards the inner side of the kiln smoothly in a state parallel to the kiln wall.

When the pressure value detected by the pressure detection device on the pushing device pushing a certain corner of the electrode brick is larger than the pressure value detected by the pressure detection devices on the other three pushing devices, the glass liquid resistance of the certain corner of the electrode brick is indicated to be larger, at this time, the control device 200 can control the oil inlet amount of the flow regulating device of the pushing device with the larger pressure value to be larger, and/or the control device 200 can control the oil inlet amount of the flow regulating device of the other three pushing devices with the smaller pressure value to be smaller, so that the pushing speeds of the four corners of the electrode brick are kept the same, namely, the electrode brick stably moves towards the inner side of the kiln.

When the pressure detection device on the pushing device pushing a certain corner of the electrode brick detects that the pressure value exceeds the safety threshold, the control system can control all the pushing devices to stop pushing operation in order to protect the whole pushing system and the electrode brick. Furthermore, in order to inform the staff in time, the control system can further comprise an alarm device connected with the control device, and when the pressure value detected by the pressure detection device exceeds a safety threshold value, the control device can control the alarm device to alarm so as to prompt the staff. For example, the alarm device may be provided with an alarm lamp on the electric cabinet, and the operator is prompted by controlling the alarm lamp to emit light.

When the pressure value detected by the pressure detecting means on the pushing means pushing a certain corner of the electrode brick is within the safety threshold range, but is significantly larger than the pressure value detected by the pressure detecting means on the other three pushing means, i.e. when the pressure value difference between the pushing means exceeds a specific value, the control means may control the four pushing means to push the electrode brick alternately in a clockwise or counterclockwise order, specifically, the control means controls the flow regulating means of each pushing means to be turned on and off one by one in a specific order, wherein each flow regulating means is turned on for the same time, e.g. 5 to 10 seconds, and after the flow regulating means of the previous pushing means is controlled to be turned on for a predetermined time, the flow regulating means of the pushing means is controlled to be turned off and simultaneously the flow regulating means of the next pushing means is turned on, thus alternately cycling. Because the operation mode can simulate manual operation, the safety is improved, and the working time and the workload are shortened.

In the propulsion system provided by the disclosure, as shown in fig. 1, the system may further include an electric pump station, and a carrying trolley carrying the electric pump station and the electric cabinet, where the carrying trolley may further be provided with a tool placement cabinet for storing a fixing device, a telescopic member, a circular push plate and the like in a non-working state, and the bottom of the carrying trolley may be provided with rollers, so that the carrying trolley may be moved to the vicinity of the charged body to be propelled.

The electric pump station may include an oil tank for storing hydraulic oil, an electric oil pump connected to the oil tank, a motor for driving the electric oil pump to operate, and an oil path connected between a plurality of expansion members of the electric oil pump, the oil path may include a main pipe, a plurality of branches branching from the main pipe, each branch being connected to a cylinder body of the hydraulic cylinder, for example, and each branch may be provided with the flow regulator. Further, the electric oil pump may employ a variable pump in order to enable the output flow rate to adjust the total oil amount into the main line as needed.

Wherein, in order to be convenient for this flow control device of manual control, can also set up the display screen on this electric cabinet to the pressure value that the pressure detection device detected is shown, thereby is convenient for the manual work according to the oil feed volume size of this flow control device of this pressure value adjustment, perhaps closes this flow control device.

Before the electrode brick pushing operation, the gap between the electrode brick and the kiln wall needs to be heated, so that the solid glass paste remained in the gap is gradually softened, and the pushing of the electrode brick is facilitated. The method adopted in general is to expose the insulating cotton wrapping electrode bricks on the edge of the outer part of the kiln wall so as to heat the edge of the electrode bricks. In the electrode brick advancing process, in order to prevent the heat preservation cotton from being carried into the gap, the heat preservation cotton needs to be taken away, so that the softened glass paste in the gap becomes hard gradually, the electrode brick and the kiln wall are adhered into a whole, and the pushing resistance is increased. Therefore, the automatically-controllable propelling system provided by the disclosure can effectively solve the problem that the electrified body such as electrode bricks is blocked in the propelling operation of glass paste, and the electrode bricks are rapidly and safely pushed in place by simultaneously propelling the plurality of propelling devices or alternately propelling the electrode bricks according to a specific sequence, and the automatically-controllable propelling system is simple and easy to operate, only needs 1 to 2 operators, saves a large amount of manpower, avoids the workers from working at high temperature close to the periphery of the kiln wall, and has great popularization applicability and economic convenience.

The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, but the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solutions of the present disclosure within the scope of the technical concept of the present disclosure, and all the simple modifications belong to the protection scope of the present disclosure.

Moreover, any combination between the various embodiments of the present disclosure is possible as long as it does not depart from the spirit of the present disclosure, which should also be construed as the disclosure of the present disclosure.
