By making the above arrangement so that the bottom height of the upper die plate on the receiving plate 10 is smaller than the bottom height of the upper die plate on the placing plate 6, at this time, the bottom of the inner side of the die plate on the receiving plate 10 is formed with an exposed area for the contact of the lower push plate 12. Further, the lower push plate 12 is located outside the range of the upper template of the placing plate 6 and is not interfered by the upper template of the placing plate 6. Meanwhile, in the process that the templates fall from the outer side ends of the placement plates 6 to the spacing areas 9, the tops of the outer side surfaces of the templates are contacted with the inner surfaces of the side baffle plates 7 to displace downwards, so that after the templates fall to the tops of the bearing plates 10, the outermost templates on the placement plates 6 are completely located on the placement plates 6 and are effectively supported.
As shown in fig. 7, the outer side of the frame 1 is provided with a supporting wheel 13, the supporting wheel 13 is used for rolling on the surface of the pier hole inner wall surface upper template, and the supporting wheel 13 is provided with a group on the upper side and the lower side of the height direction of the frame 1, and the distance between the outer side end of the bearing plate 10 and the pier hole inner wall surface is greater than the thickness of the single template and less than the sum of the thicknesses of the two templates. As shown in fig. 6, the outer side end of the bottom of the supporting plate 10 is fixedly provided with a backup plate 14, the top of the outer side end of the backup plate 14 is flush with the outer side end of the supporting plate 10, and a space matched with the thickness of a single template is formed between the bottom of the outer side end of the backup plate 14 and the inner wall surface of the pier hole.
Through so setting for the template can drop to the region between backup plate 14 and the pier hole internal wall after breaking away from the top of accepting board 10, and the distance between backup plate 14 and the pier hole dado from top to bottom reduces gradually for the template is constantly hugged closely to pier hole dado surface at the in-process that drops, with this, has the effect of automatically hugging closely on the pier hole internal wall and preventing the template from falling under self gravity effect after making the template break away from accepting board 10. When the platform part is wholly displaced from bottom to top in the pier hole and passes through the template on the inner wall surface of the pier hole, the supporting wheel 13 and the backup plate 14 further press the template on the inner wall surface of the pier hole.
As shown in fig. 3, 6, 10 and 11, the inner side surface of the lower push plate 12 is fixedly connected with a supporting rod 15, the bottom of the inner side surface of the supporting rod 15 is fixedly connected with a push block 16, the inner side surface of the push block 16 is fixedly connected with a screw rod 17, a threaded sleeve 18 is sleeved outside the screw rod 17, the threaded sleeve 18 is rotatably mounted on the outer surface of the placement plate 6, a synchronizing shaft 19 is fixedly connected between opposite ends of two threaded sleeves 18 positioned on the same side, the synchronizing shaft 19 is connected with a rotating handle 20, and threads of the two screw rods 17 positioned on the same side are reversely arranged.
Through the arrangement, the rotating handle 20 is directly rotated forward, the rotating handle 20 simultaneously drives the threaded sleeves 18 at two ends of the synchronous shaft 19 to synchronously rotate through the synchronous shaft 19, at the moment, the threaded sleeves 18 drive the push blocks 16 to outwards displace through the screw rods 17, the push blocks 16 drive the lower push plates 12 to outwards displace through the supporting rods 15, and the lower push plates 12 push the templates on the bearing plates 10 to the inner wall surfaces of pier holes after contacting the templates on the bearing plates 10, so that the templates are separated from the bearing plates 10, and the function of paving the templates is realized.
And after the template is clung to the inner wall surface of the pier hole, the state that the lower push plate 12 extrudes the template is kept, so that the template can be positioned, and the template nailing machine has the function of more conveniently nailing the template on the inner wall surface of the pier hole by operators. By reversely rotating the rotating handle 20, the lower push plate 12 can conveniently adjust the position and state of the template laid on the inner wall surface of the pier hole after the extrusion action of the template is removed, and in the process, the template can be limited by the backup plate 14 to prevent the template from falling. After the template position is adjusted, the knob 20 can be rotated forward again so that the lower push plate 12 positions the template after the position adjustment.
As shown in fig. 10 to 12, the inner side end of the bearing plate 10 is fixedly connected with a lifting sliding sleeve 21, the lifting sliding sleeve 21 is slidably arranged on the outer surface of the placing plate 6 in the height direction, the inner top wall of the lifting sliding sleeve 21 comprises a first horizontal plane 22 extending inwards and outwards, a first inclined plane 23 extending upwards from the outer side end of the first horizontal plane 22 and a second horizontal plane 24 extending outwards from the outer side end of the first inclined plane 23, the top surface of the push block 16 comprises a second inclined plane 25 extending inwards and outwards and a third horizontal plane 26 extending outwards from the outer side end of the second inclined plane 25, the inclination angle of the second inclined plane 25 and the first inclined plane 23 is the same, a through groove 27 for the displacement of the supporting rod 15 is formed in the top of the lifting sliding sleeve 21, and the lower push plate 12 is located above the lifting sliding sleeve 21.
By so doing, the receiving plate 10 is connected with the lifting slide 21, and therefore, when the lifting slide 21 is lifted on the placement plate 6, the receiving plate 10 is lifted in synchronization with the lifting slide 21. When the pushing block 16 is displaced from inside to outside and drives the lower pushing plate 12 to push the template on the bearing plate 10 to the inner wall surface of the pier hole, the lifting sliding sleeve 21 has a downward displacement stroke. And in the course of downward displacement of the lifting slide sleeve 21, the receiving plate 10 carries the formwork at its top while being displaced downward. With this, can make push pedal 12 with the template when pushing away on the pier hole internal wall, the contact position of push pedal 12 and template is close to the middle part of template more in the direction of height, and then when making the template outwards pushed away by push pedal 12 down, the contained angle between template and the pier hole internal wall is less, the template of being convenient for breaks away from the joint board 10 more and falls into the backup plate 14 and the pier hole internal wall between the clearance, improves the effect that the template dropped under self gravity effect to the reinforcing template reaches the performance of presetting the state on the pier hole internal wall automatically under the effect of gravity.
Further, when the receiving plate 10 is at the highest position, the height of the top of the template positioned in the interval area 9 is larger than the height of the bottom end of the side baffle 7, when the receiving plate 10 is at the lowest position, the height of the top of the template positioned in the interval area 9 is smaller than the height of the bottom end of the side baffle 7, when the template positioned in the interval area 9 is pushed away from the receiving plate 10 by the push plate 12, the second horizontal plane 24 is supported on the third horizontal plane 26, and when the push plate 12 is positioned at the innermost position in the displacement direction, the first horizontal plane 22 is supported on the third horizontal plane 26, and the second inclined plane 25 is positioned outside the lifting sliding sleeve 21.
Through so setting for the template that is located interval 9 can be spacing by side shield 7, makes the template in interval 9 can not empty, simultaneously, the template medial surface in interval 9 with place on the board 6 outside template contact, and place on the board 6 the template is supported by push pedal 11, and then, make the template cooperation push pedal 11 in interval 9 have the effect of having the centre gripping location to placing the template on the board 6, improve template stability.
Specifically, during the inward-outward displacement of the push block 16, the first stroke of the outward displacement of the push block 16 causes the third level 26 to separate from the second level 24. The second inclined surface 25 is caused to pass the first inclined surface 23 in the second stroke of the outward displacement of the push block 16. In the second stroke of the outward displacement of the push block 16, the lifting sliding sleeve 21 and the receiving plate 10 are integrally displaced downward, and the third horizontal plane 26 contacts the first horizontal plane 22 while the push block 16 completes the second stroke outward, and at this time, the lifting sliding sleeve 21 is supported by the push block 16. In the third stroke of the outward displacement of the push block 16, the third horizontal surface 26 is kept in contact with the first horizontal surface 22, and at this time, the heights of the lifting slide sleeve 21 and the receiving plate 10 remain unchanged. And in the third stroke of the outward displacement of the push block 16, the lower push plate 12 contacts the die plate on the receiving plate 10 and pushes the die plate onto the inner wall surface of the pier hole.
In addition, when the push block 16is displaced inward by a stroke opposite to the third stroke, the push plate can release the squeezing action on the die plate on the inner wall surface of the pier hole, and the heights of the lifting sliding sleeve 21 and the receiving plate 10 are unchanged, so that the stroke opposite to the third stroke by the inward displacement of the push block 16 can be used as the stroke for displacing the lower push plate 12 inward when the position of the die plate on the inner wall surface of the pier hole is adjusted.
In addition, when the pushing block 16 moves inward to a stroke opposite to the second stroke, the lifting sliding sleeve 21 and the receiving plate 10 will both rise, so as to directly reduce the distance between the top of the receiving plate 10 and the bottom end of the side baffle 7 to be smaller than the height of the template itself, and further limit the template falling into the spacer 9 from the placement plate 6.
As shown in fig. 8 and 15, the inner side surface of the upper push plate 11 is fixedly provided with a sliding seat 28, the upper end and the lower end of the sliding seat 28 are respectively provided with a sleeve groove 29, the two sleeve grooves 29 are respectively sleeved at the bottom of the upper baffle plate 8 and the top of the placing plate 6 in a sliding manner, a synchronous plate 30 is fixedly connected between the two upper push plates 11 positioned behind the same side template, and a supporting plate 31 supported at the bottom of the template in the spacing region 9 is fixedly connected between the two receiving plates 10 positioned on the same side.
Through the arrangement, the slide carriage 28 is utilized to displace outwards between the placing plate 6 and the upper baffle plate 8, and the slide carriage 28 can drive the upper pushing plate 11 to push the templates on the placing plate 6 outwards, so that one template positioned at the outermost side of the placing plate 6 falls into the spacing area 9 to be supported by the bearing plate 10. In addition, two of the bearing plates 10 under the same template are connected by the supporting plate 31, so that the supporting plate 31 is matched with the bearing plates 10 to have a continuous supporting effect on the bottoms of the templates in the spacing area 9, the stability of the templates in the spacing area 9 is improved, and meanwhile, the templates can be prevented from falling from the space between the two bearing plates 10 in the process of falling from the placing plate 6 into the spacing area 9.
As shown in fig. 2 and 9, the placing plate 6 and the upper baffle plate 8 are provided with mounting grooves 32, two ends of each mounting groove 32 are provided with belt wheels 33, a driving belt 34 is sleeved between two belt wheels 33 in the same mounting groove 32, the upper baffle plate 8 and the driving belt 34 on the placing plate 6 are respectively supported at the top and the bottom of the template, one side inner wall surface of the sliding seat 28 opposite to the two sleeve grooves 29 is fixedly connected with the belt surface of the driving belt 34, and the outer side end of a wheel shaft 35 of the belt wheel 33 positioned on the inner side of the placing plate 6 extends to the outer side of the placing plate 6 and is connected with the rotating handle 20 through a driving part.
By making the above arrangement, the die plate on the placement plate 6 is supported by the belt 34 on the placement plate 6, and therefore, the slide 28 drives the push plate 11 to displace while the lever 20 is operated to rotate the belt 34, and further, the die plate on the placement plate 6 is displaced outward more flexibly and smoothly with smaller resistance and more convenient operation. In addition, the process of conveying the templates on the placing plate 6 onto the bearing plate 10 and the process of pushing the templates on the bearing plate 10 onto the inner wall surface of the pier hole can be realized by directly operating the rotating handle 20, so that the operation is further simplified.
As shown in fig. 4, 13 and 14, the transmission member includes an inner top plate 36, a plate spring 37, lifting ratchet teeth 38, a tooth spring 39, an inner top ratchet gear 40, a gear set 41 and a locking pawl 42, wherein the inner top plate 36 is slidably mounted on the outer surface of the placement plate 6 in the inner and outer directions for being pushed inward by the push block 16, the plate spring 37 is mounted between the inner top plate 36 and the placement plate 6, the plate spring 37 is compressed when the inner top plate 36 is displaced inward, the lifting ratchet teeth 38 are equidistantly interposed on top of the inner top plate 36, the tooth spring 39 is disposed between the lifting ratchet teeth 38 and the plate spring 37, the inner top ratchet gear 40 is rotatably mounted on the outer side of the placement plate 6, the gear set 41 drivingly connects the inner top ratchet gear 40 with the wheel shaft 35, the top end of the locking pawl 42 is rotatably mounted on the outer side of the placement plate 6, and the locking pawl 42 is engaged with the inner top ratchet gear 40 for preventing the transmission belt 34 from displacing the template inward.
By making the above arrangement, when the push block 16 is located at the innermost position, the inner ceiling plate 36 and the lifting ratchet 38 are also located at the innermost position in the displacement direction of the push block 16, and at this time, the inner ceiling plate 36 compresses the leaf spring 37. When the pushing block 16 is displaced outwards to drive the pushing plate 12 to push the template on the bearing plate 10 onto the inner wall surface of the pier hole, the inner top plate 36 is displaced outwards under the elastic action of the plate spring 37. At this time, since the inner top ratchet gear 40 is locked by the locking pawl 42, the lifting ratchet 38 remains stationary during the passage of the inner top ratchet gear 40, and the lifting ratchet 38 is displaced downward on the inner top plate 36 by the compression tooth spring 39 to pass over the inner top ratchet gear 40. When the junction of the third horizontal surface 26 and the second inclined surface contacts the inner side end of the first inclined surface, the inner top plate 36 is restored to the original state outwardly, and the plate spring 37 is in a free state, and the lifting ratchet 38 is separated from the inner top ratchet gear 40.
When the push block 16 is displaced inward and the third horizontal plane 26 is displaced on the second horizontal plane 24, the push block 16 pushes the inner top plate 36 inward, the inner top plate 36 continuously compresses the plate spring 37, and the lifting ratchet 38 drives the inner top ratchet gear 40 to rotate, and the inner top ratchet gear 40 drives the wheel shaft 35 to rotate through the gear set 41, so that the driving belt 34 on the placing plate 6 rotates and the upper baffle plate 8 is displaced. In this way, the function of placing the outermost one of the templates on the plate 6 into the spacer region 9 can be achieved in the last stroke of inward resetting of the lower push plate 12.
Further, the second inclined plane 25 is provided with an inner top groove 43 for inserting the outer side end of the inner top plate 36, the width of the inner top groove 43 is matched with the through groove 27, and the thickness of the inner top plate 36 is matched with the width of the inner top groove 43. At this time, the inner top groove 43 may apply an inward pushing force to the inner top plate 36 instead of the second inclined surface 25, and the contact surface thereof is larger and the pushing force is applied more uniformly.
The placing plate 6 and the upper baffle plate 8 are arranged in a state that the inner side ends of the placing plate and the upper baffle plate are inclined downwards, and the upper pushing plate 11 is perpendicular to the placing plate 6. At this time, the form placed on the top of the placement plate 6 is in a state in which the top is inclined inward, so that the placement of the form is more stable. An anti-rotation wheel 44 for rolling on the inner wall of the pier hole is installed on the side surface of the upper barrier 8. The anti-rotation wheel 44 is contacted with the inner wall surface of the pier hole, so that the template placing table can be prevented from rotating in the pier hole, and the stability and the safety are further improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
