Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of center pins, and particularly to a disassembly and assembly device for a center pin rubber sleeve assembly. Background Technique

[0002] The center pin is one of the traction structures for transmitting traction force, braking force and lateral force between the car body and the bogie. It is generally made of No. 20 forged steel, welded to the lower plane of the main frame of the car body at the upper part, and inserted into the traction pin seat of the bogie at the lower end. A center pin rubber sleeve assembly is generally provided between the center pin and the traction pin seat. The structure of the center pin rubber sleeve assembly includes an inner sleeve and a rubber sleeve bonded together to relieve the acting force of the bogie on the center pin and protect the center pin.

[0003] During maintenance, professional maintenance personnel need to replace the center pin rubber sleeve assembly. The existing disassembly method usually destroys the rubber sleeve in the center pin rubber sleeve assembly first and then disassembles the inner sleeve; while the copper bar knocking method is adopted during installation. This disassembly and installation method not only requires professional maintenance personnel to have certain fitter skills, but also is easy to damage the traction pin seat of the bogie during the disassembly process, and is very time-consuming and laborious, resulting in low disassembly and installation efficiency of the center pin rubber sleeve assembly. Summary of the Utility Model

[0004] The problem solved by the utility model is how to improve the disassembly and installation efficiency of the center pin rubber sleeve assembly.

[0005] To solve the above problems, the utility model provides a disassembly and assembly device for a center pin rubber sleeve assembly, including: a pull rod assembly, a force-bearing cross beam and a power mechanism. The abutting end of the pull rod assembly is used to abut against the bottom surface or the top surface of the center pin rubber sleeve assembly. The connecting end of the pull rod assembly is connected to the force-bearing cross beam. One end of the power mechanism is used to abut against the top wall or the bottom wall of the traction pin seat, and the other end is abutted against the force-bearing cross beam.

[0007] Optionally, the pull rod includes a galvanized steel pipe, a threaded lead screw and a matching back-tightening nut. One end of the galvanized steel pipe is connected to the abutting member, and the other end is connected to the threaded lead screw. The end of the threaded lead screw away from the galvanized steel pipe is connected to the force-bearing cross beam through the back-tightening nut.

[0023] In view of the problems existing in the above related technologies, this embodiment provides a disassembly and assembly device for the central pin rubber sleeve assembly.

[0024] As Figure 1 and Figure 2 shown, a disassembly and assembly device for the central pin rubber sleeve assembly provided by an embodiment of the present utility model includes a tie rod assembly 1, a load-bearing cross beam 2, and a power mechanism 3. The contact end of the tie rod assembly 1 is used to contact the bottom surface or the top surface of the central pin rubber sleeve assembly 4. The connection end of the tie rod assembly 1 is connected to the load-bearing cross beam 2. One end of the power mechanism 3 is used to contact the top wall or the bottom wall of the draft pin seat 5, and the other end is in contact with the load-bearing cross beam 2. The power mechanism 3 is used to drive the load-bearing cross beam 2 to move away from the draft pin seat 5 to pull out or pull the central pin rubber sleeve assembly 4 into the draft pin seat 5.

[0025] It should be noted that both the center pin rubber sleeve assembly 4 and the drawbar pin seat 5 are generally cylindrical structures. The center pin rubber sleeve assembly 4 is used to be assembled inside the cylinder of the drawbar pin seat 5. The disassembly and assembly process of the center pin rubber sleeve assembly 4 is to take out the center pin rubber sleeve assembly 4 from inside the drawbar pin seat 5. The bottom surface or top surface of the center pin rubber sleeve assembly 4 refers to the two end faces along its axial direction, and the top wall or bottom wall of the drawbar pin seat 5 refers to the two end faces along its axial direction. Additionally, when the center pin rubber sleeve assembly 4 and the drawbar pin seat 5 are assembled together, the bottom surface of the center pin rubber sleeve assembly 4 and the bottom wall of the power mechanism 3 refer to the end faces facing the same direction. For example, they are both end faces facing the positive direction of the Z axis. Similarly, the top surface of the center pin rubber sleeve assembly 4 and the top wall of the power mechanism 3 also refer to the end faces facing the same direction. For example, they are both end faces facing the negative direction of the Z axis.

[0026] Specifically, the diesel locomotive bogie includes a B-B axle type bogie. The bogie mainly consists of a frame, axle boxes, side bearings, a traction device, a foundation braking device, a hand braking device, a sand box device, and a wheel flange lubrication device, etc. The diesel locomotive includes two bogies, namely the front bogie and the rear bogie. The traction force, braking force, and lateral force are mainly transmitted between the locomotive car body and the bogie through the center pin. Therefore, the traction device of each group of bogies of the diesel locomotive adopts center pin traction. The traction device mainly consists of a drawbar pin (center pin), a bottom cover, a center pin rubber sleeve assembly, a compression sleeve, a sleeve, a canvas cover seat, and a canvas cover, etc. The disassembly and assembly device for the center pin rubber sleeve assembly includes: a pull rod assembly 1, a force-bearing cross beam 2, and a power mechanism 3. The pull rod assembly 1 includes a connecting end and an abutting end that can move relative to each other. When disassembling or installing the center pin rubber sleeve assembly 4, the abutting end of the pull rod assembly 1 abuts against the bottom surface or top surface of the center pin rubber sleeve assembly 4 to facilitate pulling out or pulling the center pin rubber sleeve assembly 4 into the drawbar pin seat 5. The connecting end of the pull rod assembly 1 is connected to the force-bearing cross beam 2. One end of the power mechanism 3 abuts against the top wall or bottom wall of the drawbar pin seat 5, and the other end abuts against the force-bearing cross beam 2. The force-bearing cross beam 2 is used to transmit the driving force of the power mechanism 3 to the pull rod assembly 1, so that the pull rod assembly 1 receives the driving force from the power mechanism 3 transmitted through the force-bearing cross beam 2. Under the action of the driving force, the force-bearing cross beam 2 drives the pull rod assembly 1 to move away from the drawbar pin seat 5, thereby pulling out or pulling the center pin rubber sleeve assembly 4 into the drawbar pin seat 5 to complete the disassembly or installation.

[0027] It should be noted that when installing or disassembling the center pin rubber sleeve assembly, the abutting position of the abutting end of the pull rod assembly 1 and the center pin rubber sleeve assembly 4 depends on the actual situation. The abutting position provided in this embodiment is only for illustration and is not limited.

[0028] Exemplarily, when disassembling the center pin rubber sleeve assembly, such asFigure 1 As shown, the abutting end of the drawbar assembly 1 abuts against the bottom surface of the center pin rubber sleeve assembly 4. One end of the power mechanism 3 abuts against the top wall of the drawbar seat 5, and the other end abuts against the stress beam 2. Through the driving force provided by the power mechanism 3, the stress beam 2 and the drawbar seat 5 move away from each other, thereby driving the drawbar assembly 1 to move axially along the drawbar seat 5. And because the abutting end of the drawbar assembly 1 abuts against the bottom surface of the center pin rubber sleeve assembly 4, therefore, driven by the drawbar assembly 1, the center pin rubber sleeve assembly 4 can be pulled out from the center pin hole seat 51 of the drawbar seat 5 to complete the disassembly.

[0029] Exemplarily, when installing the center pin rubber sleeve assembly, as Figure 2 shown, the abutting end of the drawbar assembly 1 abuts against the top surface of the center pin rubber sleeve assembly 4. One end of the power mechanism 3 abuts against the bottom wall of the drawbar seat 5, and the other end abuts against the stress beam 2. Through the driving force provided by the power mechanism 3, the stress beam 2 and the drawbar seat 5 move away from each other, thereby driving the drawbar assembly 1 to move axially along the drawbar seat 5. And because the abutting end of the drawbar assembly 1 abuts against the top surface of the center pin rubber sleeve assembly 4, therefore, driven by the drawbar assembly 1, the center pin rubber sleeve assembly 4 can be pulled into the center pin hole seat 51 of the drawbar seat 5 to complete the installation.

[0030] In this embodiment, by abutting the abutting end of the drawbar assembly against the bottom surface or the top surface of the center pin rubber sleeve assembly, it can ensure that the tensile force acts accurately on the center pin rubber sleeve assembly in the axial direction, avoiding damage to the drawbar seat caused by inaccurate positioning. By connecting the connecting end of the drawbar assembly to the stress beam, it is convenient to receive the driving force of the power mechanism transmitted by the stress beam, so as to facilitate the automatic disassembly and installation of the center pin rubber sleeve assembly, saving labor and time costs. Then, by abutting one end of the power mechanism against the top wall or the bottom wall of the drawbar seat and the other end against the stress beam, the power mechanism can provide a stable driving force along the axial direction of the drawbar seat, making the disassembly and installation process more controllable. At the same time, through the drive of the power mechanism, the disassembly and installation of the center pin rubber sleeve assembly can be completed quickly and simply, and it does not require professional maintenance personnel to have certain fitter skills, improving work efficiency. In addition, the disassembly and installation device for the center pin rubber sleeve assembly in this embodiment is simple to manufacture, convenient to obtain materials, and has low requirements for the use environment, with high convenience.

[0031] Optionally, the drawbar assembly 1 includes a detachable abutting member 11 and at least one drawbar 12. The abutting member 11 abuts against the bottom surface or the top surface of the center pin rubber sleeve assembly 4. The drawbar is used to penetrate the center hole of the center pin rubber sleeve assembly 4, and one end of the drawbar 12 is connected to the abutting member 11, and the other end is connected to the stress beam 2.

[0032] Specifically, the tie rod assembly 1 includes a detachable abutting member 11 and at least one tie rod 12. The abutting member 11 abuts against the bottom or top surface of the center pin rubber sleeve assembly 4 to facilitate pulling the center pin rubber sleeve assembly 4 out of or into the drawbar socket 5. Moreover, the abutting member 11 is adapted to the shape of the bottom or top surface of the center pin rubber sleeve assembly 4. The abutting member 11 is a circular steel plate or a polygonal metal plate. Exemplarily, the abutting member 11 can be a circular steel plate with a thickness of 12 mm and a diameter of 220 mm. One end of the tie rod 12 is connected to the abutting member 11, and the other end is connected to the force-bearing cross beam 2. When the number of tie rods 12 is 1, one end of the tie rod 12 can be connected to the center of the abutting member 11, and the other end can be connected to the center of the force-bearing cross beam 2 to ensure uniform force distribution. When the number of tie rods 12 is two or more, one ends of the two or more tie rods 12 are symmetrically arranged with the center of the abutting member 11 as the center and are connected to the abutting member 11, and the other ends are symmetrically arranged with the center of the force-bearing cross beam 2 as the center and are connected to the force-bearing cross beam 2 to ensure uniform force distribution.

[0033] The power mechanism 3 and the tie rod assembly 1 are respectively used to abut against the two end faces in different directions of the drawbar socket 5 and the center pin rubber sleeve assembly 4. For example, when the power mechanism 3 abuts against the top wall of the drawbar socket 5, the tie rod assembly 1 abuts against the bottom surface of the center pin rubber sleeve assembly 4. By passing the tie rod through the central hole of the center pin rubber sleeve assembly 4, the above setting can be easily achieved. Moreover, the abutting member 11 and at least one tie rod 12 are detachably connected, which can facilitate passing the tie rod through the center pin rubber sleeve assembly 4, that is, the tie rod can be first passed through the center pin rubber sleeve assembly 4, and then the abutting member 11 is installed and connected to the tie rod.

[0034] In this embodiment, as Figure 1 and Figure 2 shown, taking two tie rods 12 as an example, one ends of the two tie rods 12 are symmetrically arranged with the center of the abutting member 11 as the center and are connected to the abutting member 11 to ensure uniform force on the abutting member 11. At the same time, the other ends are symmetrically arranged with the center of the force-bearing cross beam 2 as the center and are connected to the force-bearing cross beam 2. Exemplarily, if the diameter of the abutting member 11 is 220 mm and the number of tie rods 12 is two, two tie rods 12 are symmetrically arranged and connected to the abutting member 11 on a circular ring 60 mm away from the center of the circle of the abutting member 11.

[0035] Exemplarily, the connection mode of one end of the tie rod 12 to the abutting member 11 is a fixed connection or a detachable connection, and the connection mode of the other end to the force-bearing cross beam 2 is a fixed connection or a detachable connection. The fixed connection includes welding, and the detachable connection includes threaded connection.

[0036] Optionally, the pull rod 12 includes a galvanized steel pipe, a threaded lead screw, and a matching back-tightening nut 121. One end of the galvanized steel pipe is connected to the abutting member 11, and the other end is connected to the threaded lead screw. The end of the threaded lead screw away from the galvanized steel pipe is connected to the force-bearing cross beam 2 through the back-tightening nut 121.

[0037] Specifically, the pull rod 12 includes a galvanized steel pipe, a threaded lead screw, and a matching back-tightening nut 121, as Figure 1 and Figure 2 shown, Figure 1 and Figure 2 In the figures, the shaded boundary rectangle of the pull rod 12 is the galvanized steel pipe, and the non-shaded boundary rectangle of the pull rod 12 is the threaded lead screw. One end of the galvanized steel pipe is connected to the abutting member 11, and the other end is connected to the threaded lead screw. The end of the threaded lead screw away from the galvanized steel pipe is connected to the force-bearing cross beam 2 through the back-tightening nut 121. By screwing the back-tightening nut 121 to a suitable height, the force-bearing cross beam 2 can be made to abut against the back-tightening nut 121 under the driving force of the power mechanism 3, so as to drive the pull rod assembly 1 to move under the action of the driving force of the power mechanism 3. Exemplarily, if the thickness of the abutting member 11 is 12 mm and the diameter is 220 mm, the length of the galvanized steel pipe can be set to 560 mm, the thickness can be set to 4 mm, the outer diameter can be set to 36 mm, and the threaded lead screw can be set to an M30 full-threaded lead screw with a length of 290 mm.

[0038] Optionally, the other end of the pull rod 12 is provided with an external thread structure and a matching back-tightening nut 121, and the back-tightening nut 121 is used to connect to the force-bearing cross beam 2.

[0039] Specifically, the other end of the pull rod 12 is provided with an external thread structure and a matching back-tightening nut 121, and the back-tightening nut is used to connect to the force-bearing cross beam 2, as Figure 1 and Figure 2 shown, Figure 1 and Figure 2 In the figures, the non-shaded boundary rectangle of the pull rod 12 is the external thread structure. By screwing the back-tightening nut 121 to a suitable height, the force-bearing cross beam 2 can be made to abut against the back-tightening nut 121 under the driving force of the power mechanism 3, so as to drive the pull rod assembly 1 to move under the action of the driving force of the power mechanism 3.

[0040] Optionally, a force-bearing reinforcement plate 6 is provided at the connection between the force-bearing cross beam 2 and the pull rod assembly 1, and the force-bearing reinforcement plate 6 is used to abut against the pull rod assembly 1.

[0041] Specifically, a force - bearing reinforcement plate 6 is provided at the connection between the force - bearing cross - beam 2 and the tie - rod assembly 1. The force - bearing reinforcement plate 6 is connected to the force - bearing cross - beam 2 so as to be in contact with the tie - rod assembly 1, thereby sharing the acting force between the force - bearing cross - beam 2 and the tie - rod assembly 1 under the driving force of the power mechanism 3, and extending the service life of the force - bearing cross - beam 2 and the tie - rod assembly 1. Exemplarily, the force - bearing reinforcement plate 6 can be a polygonal metal plate. For example, it is a square metal plate with a thickness of 12 mm and a length of 90 mm.

[0042] Optionally, the force - bearing cross - beam 2 is provided with a first through - hole, and the tie - rod assembly 1 penetrates through the first through - hole and is connected to the force - bearing cross - beam 2.

[0043] Specifically, according to the connection position of the tie - rod 12 and the abutting member 11 in the tie - rod assembly 1, a first through - hole is correspondingly formed on the force - bearing cross - beam 2 so that the tie - rod 12 can penetrate through the first through - hole. And on the side of the force - bearing cross - beam 2 away from the abutting member 11, by screwing the back - tightening nut 121 to a suitable height, the force - bearing cross - beam 2 abuts against the back - tightening nut 121 under the driving force of the power mechanism 3, thereby driving the tie - rod assembly 1 to move under the driving force of the power mechanism 3. Exemplarily, the size of the first through - hole is set according to the size of the tie - rod 12. For example, if the diameter of the tie - rod at the connection between the tie - rod 12 and the force - bearing cross - beam 2 is 36 mm, the diameter of the first through - hole can be set to 40 mm to ensure that the tie - rod 12 of the tie - rod assembly 1 can smoothly penetrate through the first through - hole, and the number of the first through - holes is correspondingly set according to the number of the tie - rods 12.

[0044] Optionally, the force - bearing reinforcement plate 6 is provided with a second through - hole, and the tie - rod assembly 1 penetrates through the first through - hole and the second through - hole and is connected to the force - bearing cross - beam 2.

[0045] Specifically, the first through - hole and the second through - hole have the same size to ensure that the tie - rod 12 of the tie - rod assembly 1 can smoothly penetrate through the first through - hole and the second through - hole. And on the side of the force - bearing cross - beam 2 away from the abutting member 11, by screwing the back - tightening nut 121 to a suitable height, the force - bearing cross - beam 2 makes the force - bearing reinforcement plate 6 abut against the back - tightening nut 121 under the driving force of the power mechanism 3, thereby driving the tie - rod assembly 1 to move under the driving force of the power mechanism 3.

[0046] In this optional embodiment, through the first through - hole and the second through - hole, the disassembly and installation of the disassembly and installation device for the center - pin rubber - sleeve assembly can be realized, so as to increase convenience. For example, before disassembling and installing the center - pin rubber - sleeve assembly, install the disassembly and installation device.

[0047] If the center - pin rubber - sleeve assembly is to be disassembled, such as Figure 1As shown in the figure, first, place the stressed crossbeam 2 flat above the drawbar socket 5. Insert the drawbar 12 of the drawbar assembly 1 from below the center pin rubber sleeve assembly 4, and sequentially pass through the drawbar socket hole, the first through-hole of the stressed crossbeam 2, and the second through-hole of the stress reinforcement plate 6. Connect with a back-tightening nut 121, and level the drawbar assembly 1 and the stressed crossbeam 2. Among them, the abutting member 11 of the drawbar assembly 1 is located directly below the center pin rubber sleeve assembly 4 to facilitate abutting against the bottom surface of the center pin rubber sleeve assembly 4. Then, place the power mechanism 3 between the stressed crossbeam 2 and the drawbar socket 5, make one end of the power mechanism 3 abut against the top wall of the drawbar socket 5, and the other end abut against the stressed crossbeam 2. Adjust the height of the power mechanism 3. At this time, the disassembly and assembly device is installed. When disassembling the center pin rubber sleeve assembly, start the power mechanism 3 until the center pin rubber sleeve assembly 4 is pulled out of the drawbar socket 5 to complete the disassembly.

[0048] If installing the center pin rubber sleeve assembly, as Figure 2 shown in the figure, first, insert the drawbar 12 of the drawbar assembly 1 from above the center pin rubber sleeve assembly 4 and pass through the drawbar socket hole. Among them, the abutting member 11 of the drawbar assembly 1 is located directly above the center pin rubber sleeve assembly 4 to facilitate abutting against the top surface of the center pin rubber sleeve assembly 4. Then, align the first through-hole of the stressed crossbeam 2 and the second through-hole of the stress reinforcement plate 6 with the drawbar 12, lift the stressed crossbeam 2 from bottom to top, and connect with a back-tightening nut 121. At the same time, adjust the stressed crossbeam 2 to be horizontal. Then, place the power mechanism 3 between the stressed crossbeam 2 and the drawbar socket 5, make one end of the power mechanism 3 abut against the bottom wall of the drawbar socket 5, and the other end abut against the stressed crossbeam 2. Adjust the height of the power mechanism 3. At this time, the disassembly and assembly device is installed. When installing the center pin rubber sleeve assembly, start the power mechanism 3 until the center pin rubber sleeve assembly 4 is pulled into the drawbar socket 5 to complete the installation.

[0049] Optionally, the power mechanism 3 includes at least two power devices, and the power devices include jacks and hydraulic tanks.

[0050] Specifically, the power mechanism 3 can adopt power devices such as jacks or hydraulic tanks. As Figure 1 and Figure 2 shown in the figure, the two power devices of the power mechanism 3 are evenly distributed at both ends of the stressed crossbeam 2 to ensure uniform driving force. Exemplarily, the specifications of the jacks can be selected according to the actual situation. For example, jacks with a specification of 10 tons can be adopted.

[0051] Optionally, the stressed crossbeam 2 is a cuboid structure with a hollow interior.

[0052] Specifically, the force-bearing crossbeam 2 is welded by metal steel plates. For example, the force-bearing crossbeam 2 is welded by two iron plates with a length of 600 mm, a width of 90 mm, and a thickness of 12 mm, two iron plates with a length of 600 mm, a width of 66 mm, and a thickness of 12 mm, and two square iron plates with a length of 66 mm. The two iron plates with a length of 600 mm, a width of 90 mm, and a thickness of 12 mm serve as the front and back respectively, the two iron plates with a length of 600 mm, a width of 66 mm, and a thickness of 12 mm serve as the top and bottom respectively, and the two square iron plates with a length of 66 mm serve as the left and right sides respectively.

[0053] Optionally, the length of the force-bearing crossbeam 2 matches the outer diameter of the drawbar socket 5.
