Description

Turning tool

Technical Field

The invention relates to the technical field of diesel engine design, in particular to a turning tool.

Background

The diesel generator set is a power supply device which takes a diesel engine as a prime mover and drags a generator to generate electricity. Generally, a crankshaft of the diesel engine and a rotating shaft of the generator are respectively connected through a coupler, so that when the diesel engine works, the crankshaft of the diesel engine can drive the rotating shaft of the generator to move through the coupler, and the purpose of driving the generator to generate electricity is further achieved. Before the diesel generating set is restarted after being stopped for a period of time, turning operation is generally carried out on the diesel generating set so as to judge whether a transmission part of the diesel engine can normally work or not, the phenomenon that the transmission part of the diesel engine is blocked is prevented, and the diesel engine is further prevented from being damaged; or turning the vehicle for equipment maintenance.

At present, diesel generating set's barring mode mainly has two kinds, and one of them barring mode is between two bolts through going into the one end card of crowbar the shaft coupling, and the staff holds the other end of crowbar to through the crowbar to the shaft coupling application of force, make the shaft coupling drive bent axle and pivot rotate together, thereby carry out the barring. However, because the piston assembly of the crankshaft of the diesel engine and the rotor of the generator have large mass, the adoption of the method needs a plurality of workers to perform barring at the same time, and a great deal of manpower is consumed. Moreover, when the crowbar is adopted for turning, the rotational inertia of the diesel engine is large, the diesel engine cannot be stopped, the turning speed is not controllable, and then some workers cannot take out the crowbar in time after applying force to the coupler through the crowbar, so that potential safety hazards are easily caused. Another barring method is to use a torque multiplier to barring a crankshaft of the diesel engine. The torque multiplier is the cylinder, and the chamber that holds has been seted up to the one end of cylinder, and the spanner is installed to the other end. When the vehicle is turned, the crankshaft is disengaged from the coupler, one end of the crankshaft close to the coupler is placed in the accommodating groove of the torque multiplier, and the crankshaft in the accommodating cavity can be clamped tightly by the torque multiplier, so that the crankshaft and the torque multiplier are prevented from falling off. After the torque multiplier is installed, the wrench is rotated to drive the torque multiplier to rotate, so as to drive the crankshaft to rotate for turning. However, when the method is adopted for turning over, the half coupling connected with the crankshaft of the diesel engine and the half coupling connected with the generator need to be separated, after turning over is completed, the crankshaft and the coupling also need to be subjected to coupling centering operation, even the bolts of the coupling need to be replaced, and the turning over mode is large in workload and long in working time, and consumes a large amount of manpower and material resources.

At present, some barring tools can realize barring without detaching the coupler, specifically, a driving device drives the gear ring to rotate through a circumferential fixed connection gear ring of the coupler, so that the gear ring drives the coupler to rotate and further realizes barring. However, the driving device has no special supporting structure, and the driving device needs to be temporarily supported by other parts on site during turning, so that turning is inconvenient.

To sum up, the current barring instrument has the technical problems that barring speed can not be adjusted, safety accident easily occurs, barring is inconvenient and a large amount of manpower and material resources are consumed.

Disclosure of Invention

Based on this, it is necessary to provide a barring tool which can save manpower and material resources, is not easy to cause safety accidents, can adjust the barring speed and is convenient to barring aiming at the technical problems that the existing barring tool cannot adjust the barring speed, is easy to cause safety accidents, is inconvenient to barring and consumes a large amount of manpower and material resources.

Referring to fig. 1, an embodiment of the present application provides a turning tool 100. The barring tool 100 is used for barring a diesel generator set.

The diesel generator set comprises a diesel engine, a coupler 300 and a generator. The diesel engine is including stretching out the bent axle 200 of diesel engine body, and the generator is including stretching out the pivot (not shown) of generator body, and the bent axle of diesel engine passes through shaft coupling 300 fixed connection with the pivot of generator to the diesel engine during operation, the bent axle 200 of diesel engine can drive the pivot motion of generator through shaft coupling 300, and then realizes driving the purpose of generator electricity generation. When the diesel engine works, a large amount of heat is generated, the temperature of the diesel engine is increased due to the heat, and parts of the diesel engine are burnt out due to overhigh temperature. Therefore, the diesel engine can all be equipped with the heat sink, and the heat sink is connected with the water pipe, and the heat sink passes through the water pipe and carries water to the position that the diesel engine needs the cooling to cool down to this position that needs the cooling. To secure the water hose in place, a water hose mount 400 is typically provided. The water pipe base 400 is fixed on the ground, and the water pipe base 400 is located at the lateral side of the coupler 300 and has a certain distance from the coupler 300. One section of the water pipe passes through the preformed hole of the water pipe base 400 to limit the water pipe.

Specifically, when the turning tool 100 is used for turning the crankshaft 200 of the diesel engine, the first direction X is along a horizontal direction and along an axial direction of the crankshaft 200, the second direction Y is a vertical direction, and the third direction Z is along a horizontal direction and perpendicular to the first direction X. In the diesel generator set, the water pipe base 400 and the coupling 300 have a positional difference in the three directions, respectively.

The turning tool 100 includes a ring gear 110, a gear set, and a carrier. Referring to fig. 1 and 2, the ring gear 110 is used to be sleeved and fixed on one end of the crankshaft 200 of the diesel engine close to the coupler 300. The gear set includes at least one gear, a main shaft 122, and a mount 125. At least one gear is engaged with the ring gear 110, the main shaft 122 is coaxially connected with the at least one gear, and the main shaft 122 is connected with the mounting portion 125. The bracket 130 can support the mounting portion 125.

Referring to fig. 1, before the barring tool 100 is used for barring a diesel generator set, a gear ring 110 in the barring tool 100 is sleeved and fixed at one end of a crankshaft 200 close to a coupler 300 in advance, and the crankshaft 200 is fixedly connected with a rotating shaft of a generator through the coupler 300.

In the turning tool 100, the gear train is coupled to the mounting portion 125 through the main shaft 122, and the mounting portion 125 is supported by the bracket, so that the bracket can indirectly support the gear train. Because the water pipe base 400 is located at the lateral side of the coupler 300 and has a certain distance from the coupler 300, when the barring tool 100 is used for barring a diesel engine and a generator, the bracket can be installed on the water pipe base 400, so that the bracket can be located at the lateral side of the coupler 300, and the gear set and the bracket can be jointly arranged at the lateral side of the coupler 300. Thus, at least one gear of the gear set may be conveniently meshed with the ring gear 110 when the gear set is installed.

When the gear is turned, at least one gear in the gear set is coaxially connected with the main shaft 122, so that the main shaft 122 can drive the gear coaxially connected with the main shaft to rotate, and the gear can rotate to drive the gear meshed with the gear ring 110 to rotate, so that the gear ring 110 is driven to rotate. Because ring gear 110 and bent axle 200 fixed connection, shaft coupling 300 is connected with bent axle 200 and pivot again to when ring gear 110 rotated, can drive shaft coupling 300, bent axle 200 and pivot and rotate jointly, in order to carry out the barring.

Therefore, when the diesel engine generator set is assembled, the gear ring 110 and the crankshaft 200 can be fixed in advance, so that when the diesel engine generator set is turned, turning can be performed only by meshing one gear in the gear set with the gear ring 110 which is installed in advance, the crankshaft 200 does not need to be separated from the coupler 300 for installing the gear ring 110 for many times, and the diesel engine generator set is convenient to install and time-saving and labor-saving. Since torque is transmitted to crankshaft 200 through main shaft 122, gear, and ring gear 110, a worker may operate main shaft 122 to rotate, and the turning speed may be controlled by the worker, so that the turning speed may be adjusted, and safety accidents may not occur easily. Because water pipe base 400 and ground fixed connection belong to the structure that diesel generating set itself was equipped with, consequently, with support mounting in water pipe base 400, the structure that can make full use of diesel generating set itself was equipped with realizes the installation to the support to make things convenient for the installation of support, and then also make things convenient for the support to support the gear train, need not to increase other bearing structure temporarily when barring promptly and support the gear train, consequently the barring is more convenient.

In one embodiment, a plurality of through holes (not shown) are formed at the axial end surface of the ring gear 110 at regular intervals along the circumferential direction of the ring gear 110, and a plurality of threaded holes (not shown) are formed at the axial end surface of the coupling 300 at regular intervals along the circumferential direction of the coupling 300, and the through holes correspond to the threaded holes. The bolts pass through the through holes of the ring gear 100 and are in threaded fit with the threaded holes of the coupler 300, so as to fixedly connect the ring gear 110 with the coupler 300, thereby ensuring the fixation of the ring gear 110 with the crankshaft 200.

In one embodiment, the turning tool further includes a driving portion (not shown) connected with the spindle 122. Specifically, since the driving portion is connected to the main shaft, the driving portion is rotated to drive the main shaft 122 to rotate, so as to transmit torque to the gear coaxially connected to the main shaft, thereby driving the gear to rotate. The driving part drives the main shaft 122 to rotate, so that the torque is transmitted, and the structure is simple and the operation is convenient.

The driving part can be a manual operating handle, and the operating handle is rotated manually, so that the main shaft 122 is driven to rotate to transfer torque. The driving portion may also adopt an automatic driving device such as a motor, etc. to automatically drive the main shaft 122 to rotate.

In one embodiment, spindle 122 has a polygonal aperture 101 at one end. One end of the driving part is fitted into the polygonal hole 101, thereby driving the main shaft 122 to rotate. The polygonal hole 101 is, for example, a quadrangular hole or a hexagonal hole.

In other embodiments, one end of the driving part may be provided with a polygonal hole, and one end of the main shaft is matched with the polygonal hole, so as to drive the main shaft to rotate. The polygonal hole is, for example, a quadrangular hole, or a hexagonal hole.

In one embodiment, the drive section is removably coupled to one end of the spindle 122. In this embodiment, the drive section comprises two drive elements, one of which is an operating handle and the other of which is a motor. Because the drive portion can be dismantled with main shaft 122 and be connected, consequently, operating handle and motor can be dismantled with main shaft 122 and be connected respectively to when operating handle is connected with main shaft 122, can drive main shaft 122 rotation through artifical rotation operating handle, and then transfer moment. When the motor is connected to the main shaft 122, the main shaft 122 can be driven by the motor to rotate, so as to transmit torque. The barring tool 100 can realize the conversion between the manual barring and the electric barring according to different working conditions.

Referring to fig. 2, in an embodiment, the at least one gear includes a driving gear 121 and a driven gear 123 sequentially arranged along the third direction Z. The drive gear 121 is coaxially connected with the main shaft 122. The driven gear 123 is engaged with the driving gear 121 and the ring gear 110, respectively. Specifically, in the present embodiment, the driving gear 121 and the main shaft 122 may be coaxially connected by a key connection. Because two gears are arranged and the main shaft 122 is connected with the driving gear 121, the driven gear 123 is arranged between the gear ring 110 and the driving gear 121 at an interval, so that the distance between the gear ring 110 and the driving gear 121 along the third direction Z is increased, therefore, the distance between the main shaft 122 and the coupler 300 along the third direction Z can be increased, and further, a sufficient space can be reserved between the main shaft 122 and the coupler 300, so that when the driving part drives the main shaft 122 to rotate, the driving part does not collide with the coupler 300, and the sufficient space is reserved between the main shaft 122 and the coupler 300, so that the main shaft 122 can be adapted to driving parts with different sizes, and the application flexibility of the turning tool 100 can be improved.

In other embodiments, the at least one gear may be one gear or three or more gears as long as the torque can be transmitted and the driving handle does not collide with the coupling.

Referring to fig. 2, in one embodiment, the gear set further includes a driven shaft 124, the driven gear 123 is coaxially connected with the driven shaft 124, and the driven shaft 124 is connected with the mounting portion 125. Specifically, the driven gear 123 and the driven shaft 124 can be coaxially connected through a key connection. The driven shaft 124 is used for supporting the driven gear 123, and the driven gear 123 rotates to drive the driven shaft 124 to rotate.

Referring to FIG. 2, in one embodiment, the mounting portion 125 is a gearbox. The gear set is positioned in the gear box, so that the gear set is not exposed, and the gear set is protected.

Referring to fig. 1, in one embodiment, the bracket 130 has a protruding portion. When the bracket 130 is used to connect with the water pipe base 400, the protruding portions protrude from the water pipe base 400 along the first direction X, the second direction Y, and the third direction Z, respectively. The mounting portion 125 is provided on the protruding portion.

Since the gear ring 110 is sleeved at one end of the crankshaft 200 close to the coupler 300, the coupler 300 and the water pipe base 400 have position differences in three spatial directions, respectively, and therefore, the gear ring 110 and the water pipe base 400 have position differences in three spatial directions, respectively.

When the gear is turned, the driven gear 123 needs to be engaged with the ring gear 110, and thus the engagement position of the driven gear 123 with the ring gear 110 must be the same, so that the driven gear 123 needs to be placed in the immediate vicinity of the ring gear 110.

In the present embodiment, in order to compensate for the position difference between the water pipe base 400 and the gear ring 110 in three directions, the bracket 130 is provided with a protruding portion, and the protruding portion protrudes from the water pipe base 400 in the first direction X, the second direction Y, and the third direction Z, respectively, so that the protruding portion of the bracket can be used to compensate for the position difference between the gear ring 110 and the water pipe base 400 in three spatial directions. Because the convex part of the bracket makes up the position difference between the water pipe base 400 and the gear ring 110 in three directions, the mounting part 125 is directly mounted on the convex part of the bracket, and the driven gear 123 can be meshed with the gear ring 110 only by slightly adjusting the position of the mounting part 125, so that the mounting part 125 is more convenient to mount. Since the bracket has the protruding portion, the structure of the mounting portion 125 can be designed to be simpler, simplifying the overall structure of the barring tool 110. When the turning tool 100 is not used, only the mounting part 125 can be detached, so that the driven gear 123 is not meshed with the gear ring 110, and the turning tool 100 is not required to be detached wholly, so that the mounting part 125 is simple in structure and convenient to mount and detach.

Referring to fig. 1, a cradle includes a first support module and a second support module. The first supporting module has a first protruding portion protruding from the water pipe base 400 along the first direction X. The second supporting module is disposed on the first protruding portion of the first supporting module, and the second supporting module has a second protruding portion protruding from the water pipe base 400 along the second direction Y and the third direction Z, respectively. The mounting portion 125 is provided on the second projection portion.

Specifically, since the first protruding portion protrudes from the water pipe base 400 along the first direction X, and the second supporting module is disposed on the first protruding portion of the first supporting module, the second supporting module protrudes from the water pipe base 400 along the first direction X. And because the second supporting module has the second protruding portion, and the second protruding portion protrudes from the water pipe base 400 along the second direction Y and the third direction Z, i.e. the second protruding portion protrudes from the water pipe base 400 along the first direction X, the second direction Y and the third direction Z, respectively, therefore, the position difference between the water pipe base 400 and the gear ring 110 in three directions is compensated by the first protruding portion and the second protruding portion, and when the mounting portion 125 is disposed on the second protruding portion, the position difference between the mounting portion 125 in three directions is adjusted by the bracket. Because the mount 125 supports the gear set, the gear set may mesh with the ring gear 110. It can be seen that the first protruding portions of the first support module are mainly used to compensate for the difference in position of the water pipe base 400 and the ring gear 110 in the first direction X, and the second protruding portions of the second support module are mainly used to compensate for the difference in position of the water pipe base 400 and the ring gear 110 in the second direction Y and the third direction Z.

Through the bulge that will adjust water pipe base 400 and ring gear 110 along the difference in position of three direction, decompose into first bulge and second bulge two parts to can adjust alone and adjust the difference in position of water pipe base 400 and ring gear 110 along the not equidirectional, it is convenient to adjust, and makes support structure simple, also makes things convenient for the installation and the dismantlement of support simultaneously.

Referring to fig. 3 to 5, the first support module includes a first support part 131, a second support part 132, and a pad plate 133. The first supporting portion 131 is used to be fixedly connected with the water pipe base 400, and the first supporting portion 131 has a first protruding portion. The second supporting portion 132 is used for being fixedly connected with the water pipe base 400, the second supporting portion 132 is provided with a first protruding portion, and the second supporting portion 132 and the first supporting portion 131 are arranged at intervals along the third direction Z. The pad plate 133 is disposed at the first protruding portion of the first supporting portion 131 and the first protruding portion of the second supporting portion 132, and is fixedly connected with the first protruding portions, and the second supporting module is disposed at the pad plate 133.

Since the pad 133 is disposed at the first protruding portion of the first support 131 and the first protruding portion of the second support 132, the pad 133 also protrudes from the water pipe base in the first direction X. Therefore, when the second supporting module is disposed on the pad 133, the second supporting module can also protrude from the water pipe base along the first direction X. Specifically, the first protrusion of the first support 131 may be the first support plate 1313. The first protruding portion of the second support part 132 may be a second support plate 1323.

Since the first supporting module makes up the position difference between the water pipe base 400 and the gear ring 110 along the first direction X through the first supporting plate, the second supporting plate and the backing plate 133, it can be seen that the first supporting module has a simple structure, is light and saves materials.

Referring to fig. 3 to 4, the first support part 131 includes: a first base 1311 and a first body 1312. The first base 1311 is used to connect with the hose base 400. One end of the first body 1312 along the second direction Y is fixedly connected to the first base 1311.
