[0039] Part of the components of the rail vehicle has the characteristics of large volume and large weight, especially the components assembled at the bottom of the car body, it is difficult to use a crane and other equipment, and a lot of manpower and time is needed in the assembly operation.In the related art, the anti-roll torsion bar of the rail vehicle is an important part of the bogie system, mainly used for inhibiting the roll movement of the car body, thereby improving the comfort of passengers, and the anti-roll torsion bar is fixed at the bottom of the bogie frame through two friction rubber sleeves distributed at both ends, and is connected with the car body through two connecting rods.If the car body rolls, the anti-roll torsion bar will be twisted, and the process of twisting the anti-roll torsion bar offsets the roll movement of the car body, thereby reducing the roll of the car body.The anti-roll torsion bar is a key component of the running safety of the rail vehicle, so it needs to be checked at a certain interval, and if the anti-roll torsion bar has permanent deformation, cracks or node rupture, the anti-roll torsion bar needs to be replaced to ensure that the anti-roll torsion bar is within the normal use range and ensures the safe operation of the train.When the check value of the anti-roll torsion bar is abnormal, the anti-roll torsion bar needs to be replaced, and at least 4 workers are needed to cooperate in the replacement work.After the anti-roll torsion bar mounting bolts are disassembled, two workers compress the left and right friction rubber sleeves of the anti-roll torsion bar on both sides with clamps, and then two workers remove the anti-roll torsion bar, which consumes a lot of manpower and time.In addition, during the replacement of the anti-roll torsion bar, the anti-roll torsion bar may fall, causing injury to personnel and equipment, and there is a safety hazard.

[0040] It can be understood that the embodiment of the first aspect of the utility model proposes a rail vehicle assembly tool, which is a special auxiliary equipment for rail vehicle manufacturing and maintenance, and the core function is to provide efficient and stable assembly support, especially when installing components at the bottom of the car body, which can significantly reduce the labor intensity of workers and improve the work efficiency.

[0041] Reference Figure 7, the assembly tool of the rail vehicle includes a horizontal base 100, two air cylinders 200 and a gas delivery assembly 300. The horizontal base 100 is the basic support structure of the assembly tool, and its design needs to ensure sufficient stability and load-bearing capacity. The horizontal base 100 is usually made of high-strength metal materials, with high strength and wear resistance to adapt to the complex environment of the rail vehicle manufacturing site. The shape and size of the horizontal base 100 need to be accurately calculated to ensure that both ends can be stably placed on the steel rail 140, maintaining the horizontal state of the entire tool and providing a stable platform for subsequent assembly operations. In addition, the bottom surface of the horizontal base 100 can be provided with anti-skid texture or anti-skid device to prevent sliding during operation and ensure safety, or a buckle can be provided on the bottom surface of the horizontal base 100 to be fixed on the steel rail 140, providing a more stable support foundation.

[0042] The assembly tool is equipped with two air cylinders 200, which are installed at both ends of the horizontal base 100, and the air cylinders 200 are vertically arranged, aiming to use the vertical extension and contraction of the air cylinders 200 to realize the lifting of the upper parts of the clamp mounting plate 210. By replacing air cylinders 200 of different specifications, a stroke of 0 to 1000 mm can be achieved. The air cylinder 200 is a high-performance pneumatic component with fast response, high thrust output and low maintenance cost. The clamp mounting plate 210 is a connecting component at the upper end of the air cylinder 200, used to install and fix various special clamps. The clamps are customized according to the shape and size of the parts to be assembled, ensuring accurate positioning of the parts. The clamp mounting plate 210 is designed to have sufficient rigidity and flexibility, which can ensure the stability of the clamp and facilitate the quick replacement of different clamps to adapt to different assembly tasks, such as four bolt mounting holes in the clamp mounting plate 210 to facilitate the fixation of the clamp.

[0043] The gas delivery assembly 300 is a key part connecting the external gas source and the air cylinder 200, including a switch valve 310 and two control valves 320. The switch valve 310 is responsible for controlling the on-off of the gas path of the entire system, ensuring safety and flexibility during operation. The control valve 320 is responsible for adjusting the flow direction and pressure of the gas, and each control valve 320 corresponds to a connected air cylinder 200. The control valve 320 has an inlet pipe 321, a gas delivery pipe 322 and a return pipe 323. The inlet pipe 321 connects the switch valve 310 to introduce high-pressure gas from the external gas source into the control valve 320; the gas delivery pipe 322 delivers gas to the piston cavity of the air cylinder 200 to drive the piston to move; and the return pipe 323 returns the gas discharged from the air cylinder 200 to the outside of the system, forming a complete gas path.

[0044] The working principle of the assembly tool for rail vehicles is based on pneumatic transmission technology, which realizes precise control of the air cylinder 200 by controlling the flow and pressure of gas. When the on-off valve 310 is opened, high-pressure gas from the external gas source enters the control valve 320 through the air inlet pipe 321. According to the work requirements, the operator adjusts the flow direction of the gas through the control valve 320, so that the gas enters the lower chamber or the upper chamber of the air cylinder 200, pushing the piston to move upward or downward. The movement of the piston drives the clamp mounting plate 210 and the components on it to rise and fall, thereby realizing the lifting and positioning of the components, facilitating assembly.

[0045] The use of the assembly tool for rail vehicles is as follows:

[0046] I. Tool positioning: Place the horizontal base 100 on both ends of the steel rail, adjust to the horizontal state, and ensure stable position. II. Connect the gas source: Connect the on-off valve 310 of the gas delivery assembly 300 with the external gas source, and ensure stable gas supply. III. Turn on the gas source: Open the on-off valve 310 to allow high-pressure gas to enter the gas delivery assembly 300. IV. Adjust the control valve 320: According to the assembly requirements, operate the control valve 320 to make the gas enter the corresponding chamber of the air cylinder 200, and the air cylinder 200 drives the clamp mounting plate 210 to rise. V. Component assembly: Under the push of the air cylinder 200, lift the components on the clamp mounting plate 210 to the appropriate height, and facilitate workers to use for assembly work.

[0047] The assembly tool for rail vehicles greatly improves the efficiency and accuracy of assembly work, and reduces the labor and time cost. Through the pneumatic transmission technology, it realizes the rapid lifting and precise positioning of the components, reduces the manual operation of the workers, and reduces the labor intensity. In addition, the design of the tool fully considers the safety and flexibility, and can be adjusted according to different vehicle models and assembly requirements, and has strong universality. In the field of rail vehicle manufacturing, maintenance and modification, the tool has become an indispensable efficient tool, which has made great contribution to improving production efficiency and product quality.

[0048] It should be understood that the assembly tool for rail vehicles can be used to assemble various components of rail vehicles, and the following is taken as an example of assembling the anti-roll torsion bar 500.

[0049] With reference to Figures 1 to 6 , the second aspect of the embodiment of the utility model discloses an anti-roll torsion bar dismounting auxiliary device, comprising the assembly tool of the first aspect embodiment and clamp 400. The anti-roll torsion bar dismounting auxiliary device is additionally provided with the clamp 400 specially adapted to the anti-roll torsion bar 500 on the basis of the assembly tool.

[0050] The main body of the clamp 400 is composed of a solid base plate 410, which serves as the basic support structure of the entire clamp 400, ensuring stability and reliability during disassembly and assembly. The base plate 410 is fixed to the clamp 400 mounting plate 210 by four bolts. The two ends of the base plate 410 are designed with a bracket 420 and a pusher 430, as shown in Figure 2 The anti-roll torsion bar 500 includes a round bar 510 and a friction rubber sleeve 520 distributed at both ends of the round bar 510. The round bar 510 rests on the two brackets 420, which are provided with semicircular grooves to match the round bar 510 for accurate positioning of the anti-roll torsion bar 500, preventing it from falling due to shaking or tilting during disassembly and assembly, and avoiding injury to workers and equipment.

[0051] The pusher 430 is located at the end of the base plate 410 away from the gas delivery assembly 300, and is designed to compress the friction rubber sleeve 520 of the anti-roll torsion bar 500 by mechanical force. The pusher 430 is connected to one or more compression push rods 440, which are usually made of high-strength metal to ensure sufficient rigidity and durability. The compression push rod 440 directly acts on the friction rubber sleeve 520 of the anti-roll torsion bar 500 to achieve compression of the friction rubber sleeve 520. For example, the compression push rod 440 uses a bolt, and the pusher 430 is provided with a matching threaded hole. By turning the bolt, a pushing force is applied to the friction rubber sleeve 520, and the end of the bolt can be provided with a pressing piece to increase the contact area. Alternatively, the compression push rod 440 uses an automatic driving mechanism (such as an electric push rod, air cylinder, etc.) to generate a pushing force, achieving compression of the friction rubber sleeve 520 and creating the necessary space conditions for disassembly and assembly of the anti-roll torsion bar 500.

[0052] Operation process of the anti-roll torsion bar disassembly and assembly auxiliary device:

[0053] Referring to Figure 1 , first, the anti-roll torsion bar 500 is placed smoothly on the brackets 420 of the two clamps 400, ensuring that both ends of the anti-roll torsion bar 500 are stably supported, and the compression push rod 440 is operated to generate a pushing force to moderately compress the friction rubber sleeves 520 at both ends of the anti-roll torsion bar 500. Then, connect the switch valve 310 of the gas delivery assembly 300 to the external gas source, which is usually the gas tank 150 in the vehicle cabin, input high-pressure gas to the gas cylinder 200, and the gas cylinder 200 pushes the clamp 400 and the anti-roll torsion bar 500 to rise to the installation position. Only one worker is needed to complete the installation of the anti-roll torsion bar 500, and two people working together can achieve higher efficiency and further save time.

[0054] The disassembly process of the anti-roll torsion bar 500 is opposite to the assembly process. The cylinder 200 pushes the clamp 400 to rise to a position supporting the anti-roll torsion bar 500, the friction rubber sleeve 520 at both ends of the anti-roll torsion bar 500 is moderately compressed by operating the compression push rod 440, and then the connection structure of the anti-roll torsion bar 500 and the carriage is disassembled, the control valve 320 is operated, and the cylinder 200 drives the clamp 400 and the anti-roll torsion bar 500 to descend.

[0055] The technical effects of the anti-roll torsion bar disassembly and assembly auxiliary device include: 1. The labor cost and time cost are greatly reduced, and the time consumption of disassembly and assembly is shortened. 2. The labor intensity of workers is reduced, the clamp 400 supports the anti-roll torsion bar 500, the cylinder 200 provides lifting force, and the workers do not need to support the anti-roll torsion bar 500, thereby reducing fatigue. 3. The safety risk is eliminated: the accidental injury caused by manual operation is avoided, such as the anti-roll torsion bar 500 falling, and the safety of workers and equipment is ensured.

[0056] Reference Figure 3 In some embodiments of the utility model, a two-position five-way manual valve is used as the control valve 320. The manual valve is widely used in the field of industrial automation and pneumatic control due to its compact structure, simple operation and high reliability.

[0057] The two-position five-way manual valve has five interfaces, which are an input port, a gas inlet port, a gas return port and two gas exhaust ports. The input port is connected to the air inlet pipe 321 and is responsible for introducing high-pressure gas into the two-position five-way manual valve. The gas inlet port is connected to the gas inlet pipe 322, and the gas return port is connected to the gas return pipe 323, which is responsible for guiding the exhaust gas of the cylinder 200 to the gas exhaust port and to the outside. When the clamp 400 rises, the two-position five-way manual valve is in a forward working state, and the gas in the input port will be guided to the gas inlet port, and then delivered to the lower chamber of the cylinder 200 through the gas inlet pipe 322, pushing the piston to rise, and the air in the upper chamber is discharged through the gas return pipe 323 and one of the gas exhaust ports. When the clamp 400 descends, the two-position five-way manual valve is operated to change to a reverse working state, and the gas in the input port will be guided to the gas return port, and then delivered to the upper chamber of the cylinder 200 through the gas return pipe 323, pushing the piston to descend, and the air in the lower chamber is discharged through the gas inlet pipe 322 and the other gas exhaust port. The lifting and lowering of the cylinder 200 can be controlled by operating the two-position five-way manual valve.

[0058] In addition, the control valve 320 can also be an electric control valve, which controls the action of the cylinder 200 through electric control, and also can realize the controllable lifting and lowering of the clamp 400 and the anti-roll torsion bar 500.

[0059] It can be understood that the gas lock valve 330 is arranged on the gas pipe 322, through which the gas pressure of the lower chamber of the gas cylinder 200 can be locked to prevent the gas cylinder 200 from suddenly falling due to insufficient gas pressure, avoid the anti-roll torsion bar 500 from hitting the workers, and improve the safety.

[0060] Further, the exhaust ports of the two five-way manual valves are equipped with silencers 324, which effectively reduce noise pollution during use, thereby creating a more comfortable and safe working environment. The silencer 324, as an effective noise control device, is usually filled with sound-absorbing materials such as porous metal, glass fiber or foamed plastic inside, which can absorb or reflect sound waves, thereby significantly reducing exhaust noise. The silencer 324 is fixed on the two five-way manual valves by threaded connection or flange connection.

[0061] The on-off valve 310 adopts a hand slide valve, which is widely used in the field of pneumatic control due to its simple operation, sensitive response and strong durability. The design of the hand slide valve allows the operator to open and close the valve through a simple sliding action, improving work efficiency.

[0062] A gas pipe quick connector 311 is arranged at the upper end of the hand slide valve to facilitate the connection of the external gas source. The gas pipe quick connector 311 is a device for quickly connecting and disconnecting the gas pipe, which makes the disassembly and assembly of the gas pipe more convenient. In actual operation, the operator does not need to use tools, but only needs to simply insert the gas pipe into the quick connector to complete the connection. A three-way connector 312 is arranged at the lower end of the hand slide valve, which is used to connect two control valves 320 respectively. The three-way connector 312 enables the hand slide valve to output high-pressure gas to the two control valves 320 simultaneously, thereby realizing the coordinated control of multiple components in the assembly tooling.

[0063] Referring to Figure 4 , the gas cylinder 200 as the main driving component of the assembly tooling, the upper end of the piston rod 220 is fixedly connected to the center or a predetermined position of the fixture 400 mounting plate 210 through fasteners or other reliable connection methods. When the piston rod 220 moves, it can drive the fixture 400 mounting plate 210 to move synchronously, thereby realizing the positioning or clamping operation in the assembly process.

[0064] The two ends of the clamping jig 400 mounting plate 210 are respectively fixedly connected with a guide rod 230. The side wall of the air cylinder 200 or a suitable position is provided with a guide groove 240, the shape and size of the guide groove 240 are matched with the guide rod 230, so that the guide rod 230 can be smoothly installed in the guide groove 240. By using the cooperation of the guide rod 230 and the guide groove 240, on the one hand, the stability of the clamping jig 400 mounting plate 210 is increased, and the clamping jig 400 mounting plate 210 is prevented from shaking or deviating under the driving of the air cylinder 200; on the other hand, the clamping jig 400 mounting plate 210 is also provided with a guide function, so that the clamping jig 400 mounting plate 210 can be lifted along the predetermined direction.

[0065] With reference to Figures 3 to 5 In some embodiments of the utility model, the horizontal base 100 includes two connecting bed plates 110, and the two connecting bed plates 110 are connected in a detachable manner, which facilitates assembly and disassembly and facilitates storage and carrying.

[0066] The two connecting bed plates 110 are important components of the horizontal base 100, and the connecting bed plate 110 can be made of high-quality square steel pipes, which has sufficient strength and rigidity and can withstand various loads in the working process. The two connecting bed plates 110 are connected in a detachable manner, such as bolt connection, buckle connection, plug-in connection and the like. One air cylinder 200 and one control valve 320 are arranged on each connecting bed plate 110, the air cylinder 200 serves as a driving component and is responsible for providing power required in the assembly process, and the control valve 320 is used to adjust the air pressure, stroke and other parameters of the air cylinder 200 to meet the requirements of different assembly processes.

[0067] In actual application, the number and layout mode of the connecting bed plate 110, and the type and number of the air cylinder 200 and the control valve 320 can be selected according to the shape, size and assembly process requirements of the workpiece. Then, the connecting bed plates 110 are assembled together by bolts or other connection modes, and the pipeline between the air cylinder 200 and the control valve 320 is connected.

[0068] With reference to Figure 5 and Figure 6In some embodiments of the utility model, a set of efficient connecting structure is designed, first plug -in block 120 and second plug -in block 130 are installed at the opposite ends of two connecting bed plate 110 respectively, first plug -in block 120 is designed as the component with two positioning pins 121, correspondingly, two pin holes 131 are arranged on second plug -in block 130, the shape and size of the two pin holes 131 are matched with the positioning pin 121 on first plug -in block 120. Two positioning pins 121 play a key role in positioning and guiding, ensure that second plug -in block 130 can accurately connect first plug -in block 120. The material of positioning pin 121 selects high-strength, wear-resistant material to ensure stability and durability under long-time use. Positioning pin 121 can adopt cylindrical, polygonal and other shapes.

[0069] In actual operation, workers only need to align two connecting bed plate 110, then gently push, make the positioning pin 121 of first plug -in block 120 smoothly insert into the pin hole 131 of second plug -in block 130. Because of the close cooperation of positioning pin 121 and pin hole 131, stable connection is formed between two connecting bed plate 110, without additional fixing device or tool.
