Abstract
Description
Technical Field
[0001] This utility model belongs to the field of locomotive repair and maintenance technology, specifically a locomotive traction rod disassembly auxiliary device. Background Technology
[0002] The disassembly of locomotive drawbars typically requires following specific technological steps. A search revealed a method for disassembling and assembling a locomotive traction device, published on February 22, 2017, with publication number CN104494633B. This method details a complete disassembly and assembly process, including specific steps such as drawbar pin disassembly and connecting rod assembly disassembly. While this method effectively improves disassembly and assembly efficiency, its reliance on manual step-by-step operation results in a low degree of automation, still requiring significant time and labor costs for large-scale or emergency maintenance tasks. Furthermore, this method does not adequately consider the potential deformation or damage to the drawbar during disassembly, which may negatively impact the equipment's lifespan.
[0003] Therefore, there is an urgent need to design an auxiliary device for dismantling locomotive traction bars to solve the aforementioned problems of operational efficiency and equipment protection. Utility Model Content
[0004] To address the technical problems mentioned in the background section regarding the reliance on manual operation and low automation in locomotive drawbar disassembly, as well as insufficient consideration of potential deformation or damage to the drawbar, an auxiliary device for locomotive drawbar disassembly is provided. This device, through optimized structural design and functional configuration, achieves efficient and stable disassembly operations while reducing the risk of damage to the drawbar and extending the equipment's service life.
[0005] A locomotive drawbar disassembly auxiliary device includes a base, a support frame, a clamping mechanism, and an adjusting mechanism. The base is the foundation component of the device, supporting the entire device and providing a stable mounting platform. The support frame is fixedly connected to the base, supporting the drawbar and ensuring its stability during disassembly. The clamping mechanism is located within the support frame, fixing the drawbar and preventing displacement during disassembly. The adjusting mechanism cooperates with the clamping mechanism to adjust the position and angle of the drawbar to accommodate the disassembly requirements of drawbars of different specifications.
[0006] Furthermore, the base includes a first base plate and a second base plate, which are connected by bolts and secured by reinforcing ribs. The connection between the first and second base plates employs a multi-point positioning design to improve the rigidity and stability of the overall structure. The number of reinforcing ribs is even, evenly distributed between the first and second base plates, with both ends of the reinforcing ribs welded to the inner surfaces of the first and second base plates respectively, forming a stable triangular support structure.
[0007] Furthermore, the support frame includes a first support column and a second support column, which are respectively fixed to the upper surfaces of a first base plate and a second base plate. The tops of the first and second support columns are provided with arc-shaped grooves, the inner walls of which are covered with an elastic buffer layer to protect the surface of the traction rod from damage. The first and second support columns are connected by a crossbeam, the two ends of which are welded to the outer surfaces of the first and second support columns respectively. A sliding groove is provided in the middle of the crossbeam, and a slider is installed within the groove. The slider can move horizontally along the groove to adjust the position of the clamping mechanism.
[0008] Furthermore, the clamping mechanism includes a first clamping plate and a second clamping plate, which are respectively installed on both sides of the slider. The inner surfaces of the first and second clamping plates are provided with anti-slip textures, which are distributed in a cross-grid pattern to increase friction during clamping and prevent the traction rod from slipping. The first and second clamping plates are connected by a screw. One end of the screw is fixed to the outer surface of the first clamping plate, and the other end passes through the second clamping plate and is locked with a nut. The rotation of the screw causes the first and second clamping plates to move closer or further apart, thereby clamping or releasing the traction rod.
[0009] Furthermore, the adjustment mechanism includes a first adjusting rod and a second adjusting rod, which are respectively mounted on the sides of the first and second support columns. One end of each adjusting rod is connected to the support column, and the other end is connected to the slider of the clamping mechanism. The lengths of the first and second adjusting rods can be adjusted by an adjusting screw. The rotation of the adjusting screw causes the adjusting rods to extend and retract, thereby changing the overall length of the adjusting rods and thus adjusting the position of the clamping mechanism.
[0010] Furthermore, the outer surfaces of the first and second adjusting rods are provided with scale markings, which are used to indicate the length changes of the adjusting rods, making it easier for operators to accurately control the position of the clamping mechanism.
[0011] Furthermore, the base is equipped with four rollers at its bottom, which are respectively installed at the four corners of the first and second base plates. A braking device is located on the outer side of each roller, controlled by a foot pedal, to lock the rollers in place and ensure that the device does not slip during use.
[0012] The locomotive tow bar disassembly auxiliary device of this utility model has the following advantages: by setting a base and support frame, a stable installation platform and support structure are provided to ensure the stability of the tow bar during disassembly; through the cooperation of the clamping mechanism and the adjusting mechanism, the tow bar can be accurately positioned and flexibly adjusted to adapt to the disassembly needs of tow bars of different specifications; by setting anti-slip texture and elastic buffer layer, the risk of damage to the surface of the tow bar is reduced, and deformation of the tow bar due to excessive clamping force is avoided; through the design of rollers and brake device, the device is easy to move and fix, improving the convenience of operation.

[0024] In this embodiment, Figure 1 This is a schematic diagram of the overall structure of the present invention, showing the connection relationship and overall layout of the base 1, support frame 2, clamping mechanism 3 and adjusting mechanism 4.
[0025] The base 1 consists of a first base plate 5 and a second base plate 6, which are connected by bolts and fixed by reinforcing ribs 7. The reinforcing ribs 7 are evenly distributed and welded at both ends to the inner surfaces of the first base plate 5 and the second base plate 6, forming a stable triangular support structure. This multi-point positioning design improves the overall rigidity and stability of the base 1, enabling it to support the entire device and provide a reliable installation platform.
[0026] Example 2
[0027] A support frame 2 is provided based on embodiment 1.
[0028] In this embodiment, the support frame 2 includes a first support column 8 and a second support column 9, which are respectively fixed to the upper surfaces of the first base plate 5 and the second base plate 6.
[0029] The first support column 8 and the second support column 9 are provided with an arc-shaped groove 10 at their tops. The inner wall of the arc-shaped groove 10 is covered with an elastic buffer layer 11, which is made of rubber material and is used to protect the surface of the traction rod from damage.
[0030] In addition, the first support column 8 and the second support column 9 are connected by a crossbeam 12. The two ends of the crossbeam 12 are respectively welded to the side walls of the first support column 8 and the second support column 9. A sliding groove 13 is provided in the middle of the crossbeam 12, and a slider 14 is installed in the sliding groove 13. The slider 14 can move horizontally along the sliding groove 13 to adjust the position of the clamping mechanism 3. The range of movement of the slider 14 is determined by the length of the sliding groove 13, thereby ensuring that the clamping mechanism 3 can be flexibly adjusted within a certain range.
[0031] Example 3
[0032] A clamping mechanism 3 is provided based on embodiment 1.
[0033] In this embodiment, the clamping mechanism 3 is disposed within the support frame 2 and includes a first clamping plate 15 and a second clamping plate 16. The first clamping plate 15 and the second clamping plate 16 are respectively installed on both sides of the slider 14, and the inner surface is provided with anti-slip texture 18. The anti-slip texture 18 is distributed in a cross-grid pattern to increase the friction during clamping and prevent the traction rod from sliding.
[0034] The first clamping plate 15 and the second clamping plate 16 are connected by a screw 17. One end of the screw 17 is fixed to the outer surface of the first clamping plate 15, and the other end passes through the second clamping plate 16 and is locked with a nut. When the screw 17 is rotated, the first clamping plate 15 and the second clamping plate 16 move closer to or further away from each other, thereby clamping or releasing the traction rod. The design of the clamping mechanism 3 ensures that the traction rod remains stable during disassembly, avoiding damage caused by displacement.
[0035] Example 4
[0036] An adjustment mechanism 4 is provided based on embodiment 1.
[0037] In this embodiment, the adjustment mechanism 4 is used in conjunction with the clamping mechanism 3, and includes a first adjustment rod 19 and a second adjustment rod 20. The first adjustment rod 19 and the second adjustment rod 20 are respectively installed on the side of the first support column 8 and the second support column 9, with one end connected to the support column and the other end connected to the slider 14 of the clamping mechanism 3.
[0038] The lengths of the first adjusting rod 19 and the second adjusting rod 20 can be adjusted by adjusting screws. The rotation of the adjusting screws causes the adjusting rods to extend and retract, thereby changing the overall length of the adjusting rods.
[0039] In addition, the outer surface of the adjusting rod is marked with scale marks to indicate the length changes of the adjusting rod, which makes it easier for the operator to accurately control the position of the clamping mechanism 3.
[0040] Example 5
[0041] A roller 22 is provided based on embodiment 1.
[0042] In this embodiment, the bottom of the base 1 is provided with four rollers 22, which are respectively installed at the four corners of the first base plate 5 and the second base plate 6.
[0043] The roller 22 is equipped with a brake device 23 on its outer side. The brake device 23 is controlled by a foot pedal and is used to lock the position of the roller 22 to ensure that the device will not slip during use. The design of the roller 22 and the brake device 23 makes the device easy to move and fix, improving the convenience of operation.
[0044] In practical applications, the operation procedure of the locomotive tow bar disassembly auxiliary device of this utility model is as follows: First, the device is moved to the working position via roller 22, and the position of roller 22 is locked by brake device 23. Then, the tow bar is placed in the arc-shaped groove 10 of the first support column 8 and the second support column 9, ensuring that the tow bar is protected by the elastic buffer layer 11. Next, the position of clamping mechanism 3 is adjusted by adjusting the length of the first adjusting rod 19 and the second adjusting rod 20, so that the first clamping plate 15 and the second clamping plate 16 can be accurately aligned with the tow bar. Then, the screw 17 is rotated to clamp the tow bar with the first clamping plate 15 and the second clamping plate 16, ensuring that the clamping force is moderate. Finally, the disassembly operation begins. During this process, the clamping mechanism 3 and the adjusting mechanism 4 work together to ensure that the tow bar remains stable at all times, avoiding damage caused by displacement or deformation.
[0045] This utility model's locomotive drawbar disassembly auxiliary device provides a stable installation platform and support structure through a base 1 and a support frame 2. The clamping mechanism 3 and the adjusting mechanism 4 work together to achieve precise positioning and flexible adjustment of the drawbar. Anti-slip texture 18 and an elastic buffer layer 11 reduce the risk of damage to the drawbar surface, while the design of rollers 22 and a braking device 23 improves ease of operation. These design features collectively ensure the device's high efficiency and reliability in practical applications.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
