Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of railway freight car coupler components, and in particular to an anti-separation and buffering device for railway freight car couplers. Background Technology
[0002] As the core carrier of freight transport, the reliability of the coupler connection in railway freight cars directly determines transportation safety and efficiency. Currently, the coupler connection structure commonly used in railway freight cars mainly relies on the coupler's own locking mechanism for connection and fixation. However, in actual operation, factors such as complex road conditions (e.g., curved tracks, slopes), uneven cargo loading, and prolonged high-frequency vibration can easily cause wear, loosening, or even failure of the coupler locking mechanism, leading to coupler separation accidents. Such accidents not only cause cargo spillage and transportation interruptions but may also trigger major safety hazards such as train collisions and derailments.
[0003] Existing anti-separation and buffering devices for railway freight car couplers rely solely on a single locking structure to prevent separation. Wear of the locking mechanism can easily lead to loose connections, resulting in poor reliability of the anti-separation mechanism. The lack of an effective buffering structure means that the impact force during coupler connection and vibration during operation cannot be fully absorbed, exacerbating the wear of the coupler components and the coupler tongue. Furthermore, the locking force is inconvenient to adjust, making it difficult to flexibly adjust according to the coupler connection status under different working conditions, resulting in poor adaptability. Utility Model Content
[0004] The purpose of this invention is to solve the problems of poor reliability and insufficient buffering effect of existing anti-separation devices, and to propose an anti-separation and buffering device for railway freight car couplers.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for preventing separation and buffering of railway freight car couplers, comprising coupler components, coupler tongues, and a separation and buffering assembly. One end of each of the two coupler components is rotatably connected to a coupler tongue. The top of each of the two coupler components is provided with a separation and buffering assembly. The separation and buffering assembly includes threaded grooves on the top of the coupler components. Positioning screws are threadedly connected to the inner walls of the two threaded grooves. Turntables are fixedly connected to the tops of the two positioning screws. Connecting handles are rotatably connected to the interiors of the two turntables. The two ends of the connecting handles are rotatably connected to the two turntables. Limiting grooves are provided on the side walls of the two coupler components. Limiting strips are slidably connected to the inner walls of the four limiting grooves. Damping springs are fixedly connected to the inner walls of the four limiting grooves. One end of the damping spring is fixedly connected to the limiting strip. A coupler fixing handle is fixedly connected to one end of the four limiting strips. A damper is fixedly connected inside the coupler fixing handle. The telescopic end of the damper is fixedly connected to the side wall of the coupler component.
[0006] Furthermore, the surfaces of the two couplers are provided with tongue grooves, and shock-absorbing pads are fixedly connected to the inner walls of the tongue grooves and the surfaces of the couplers.
[0007] Furthermore, a motor is fixedly connected to the top of each of the two hooks, and a stop plate is fixedly connected to the top of each motor.
[0008] Furthermore, a spring is fixedly connected to the top of the abutment plate, and the top of the spring is fixedly connected to the inner top wall of the hook component.
[0009] Furthermore, the side wall of the coupler is provided with abutment grooves, and the inner walls of the two abutment grooves are fixedly connected to the telescopic end of the damper.
[0010] Furthermore, one end of each of the four limiting strips is fixedly connected to a locking block, and the surface of the locking block is locked to the inner wall of the outlet end of the limiting slide groove.
[0011] Furthermore, the inside of the coupler fixing handle is provided with mounting grooves, and the inner walls of the two mounting grooves are fixedly connected to the damper.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting up anti-separation and buffer components, the threaded groove and the positioning screw are threadedly engaged. The rotating turntable can adjust the depth of the positioning screw extending into the coupler component. The connecting handle connects the two turntables, so that the tops of the two couplers form an anti-separation lock. The damper can reduce the impact force of the coupler component on the coupler fixing handle. The damping spring in the limiting groove moves and extends with the limiting clip, absorbing the running vibration and buffering the locking impact force. Combined with the shock-absorbing pads on the inner wall of the tongue groove and the surface of the coupler component, the overall buffering performance is enhanced and the wear of components is reduced. The motor reduces the vibration through the top abutment plate and spring, improving the stability of the hook tongue. The abutment groove fixes the extension end of the damper, which can greatly reduce the impact force. The locking block prevents the limiting clip from falling out. The mounting groove fixes the damper, ensuring the stable operation of the device and adapting to the complex working conditions of railway freight cars. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a technical solution: a device for preventing separation and buffering railway freight car couplers, including coupler components 1, coupler tongues 2, and anti-separation and buffering components 3. One end of each coupler component 1 is rotatably connected to a coupler tongue 2, and the top of each coupler component 1 is provided with an anti-separation and buffering component 3.
[0022] The following section will explain the specific settings and functions of its anti-separation and buffer component 3.
[0023] In this embodiment: the anti-separation and buffer assembly 3 includes a threaded groove 31 on the top of the coupler 1, a positioning screw 32 is threadedly connected to the inner wall of the two threaded grooves 31, a turntable 33 is fixedly connected to the top of the two positioning screws 32, a connecting handle 34 is rotatably connected to the inside of the two turntables 33, the two ends of the connecting handle 34 are rotatably connected to the two turntables 33, the side walls of the two couplers 1 are provided with limit grooves 35, the inner walls of the four limit grooves 35 are slidably connected with limit clips 36, the inner walls of the four limit grooves 35 are fixedly connected with damping springs 37, one end of the damping springs 37 is fixedly connected to the limit clips 36, one end of the four limit clips 36 is fixedly connected to a coupler fixing handle 38, the inside of the coupler fixing handle 38 is fixedly connected with a damper 39, and the telescopic end of the damper 39 is fixedly connected to the side wall of the coupler 1.
[0024] The effects achieved by the above components are as follows: the initial locking adjustment is achieved by setting the threaded groove 31 and cooperating with the positioning screw 32; the turntable 33 facilitates the operator to apply force to rotate; the connecting handle 34 ensures that the top of the two coupler parts 1 are connected synchronously; the limiting slide groove 35 provides a sliding guide for the limiting clip 36 to avoid deviation during locking; and the damper 39 can reduce the impact force of the coupler part 1 on the coupler fixing handle 38.
[0025] Please see Figure 2 Specifically, the surfaces of the two car couplers 1 are provided with tongue grooves 4, and shock-absorbing pads 5 are fixedly connected to the inner wall of the tongue grooves 4 and the surface of the car couplers 1.
[0026] The effects achieved by the above components are as follows: by setting the tongue groove 4 to adapt to the rotation and engagement of the hook tongue 2, a stable movement space is provided for the hook tongue 2, and the hook tongue 2 is prevented from shaking; the shock-absorbing pad 5 buffers the collision between the hook tongue 2 and the tongue groove 4 and the car coupler 1, reduces the damage to the components during connection and operation, and at the same time weakens the transmission of vibration.
[0027] Please see Figure 4 Specifically, a motor 6 is fixedly connected to the top of the two hooks 2, and a stop plate 7 is fixedly connected to the top of the motor 6.
[0028] The effects achieved by the above components are as follows: by setting the abutment plate 7 and the spring 8, the vibration of the motor 6 can be reduced, the stability of the hook tongue 2 can be improved, the hook tongue 2 can be prevented from loosening due to vibration, the stability of the connection between the hook tongue 2 and the car hook 1 can be enhanced, and the locking requirements under different working conditions can be adapted.
[0029] Please see Figure 4 Specifically, a spring 8 is fixedly connected to the top of the abutment plate 7, and the top of the spring 8 is fixedly connected to the inner top wall of the hook component 1.
[0030] The effect achieved by the above components is as follows: by setting the spring 8, the elastic force provides a continuous pressing force to the abutment plate 7, ensuring that the abutment plate 7 is always in close contact with the inner wall of the coupler 1, while buffering the rigid impact when the abutment plate 7 moves, and avoiding damage to the components due to collision.
[0031] Please see Figure 3-4 Specifically, the side wall of the coupler 1 is provided with abutment grooves 9, and the inner walls of the two abutment grooves 9 are fixedly connected to the telescopic end of the damper 39.
[0032] The effect achieved by the above components is as follows: by setting the groove 9 to provide a fixed position for the telescopic end of the damper 39, the telescopic end of the damper 39 is prevented from shifting when it is working, ensuring that the damper 39 can stably assist the movement of the coupler fixing handle 38 and the limit strip 36, thus ensuring the buffering effect.
[0033] Please see Figure 3-5 Specifically, one end of each of the four limit strips 36 is fixedly connected to a block 10, and the surface of the block 10 is connected to the inner wall of the outlet end of the limit slide 35.
[0034] The effect achieved by the above components is as follows: by setting the locking block 10 to engage at the outlet end of the limiting slide groove 35, the sliding range of the limiting locking strip 36 is limited, preventing the limiting locking strip 36 from coming out of the limiting slide groove 35, and ensuring that the limiting locking strip 36 can always stably lock the side wall of the coupler 1.
[0035] Please see Figure 3 Specifically, the coupler fixing handle 38 has an internal mounting groove 11, and the inner walls of the two mounting grooves 11 are fixedly connected to the damper 39.
[0036] The effect achieved by the above components is as follows: by setting the mounting groove 11, a stable mounting space is provided for the damper 39, the damper 39 is fixed inside the coupler fixing handle 38, the damper 39 is prevented from shaking or shifting when it is working, and the driving force of the damper 39 is stably transmitted to the coupler fixing handle 38.
[0037] Working principle: By setting up anti-separation and buffer components 3, the threaded groove 31 and the positioning screw 32 are threadedly engaged. The rotating turntable 33 can adjust the depth of the positioning screw 32 into the coupler 1. The connecting handle 34 connects the two turntables 33, so that the top of the two couplers 1 form an anti-separation lock. The damper 39 can reduce the impact force of the coupler 1 on the coupler fixing handle 38. The damping spring 37 in the limiting slide groove 35 moves and extends with the limiting clip 36, absorbing the running vibration and buffering the locking impact force. With the shock-absorbing pad 5 on the inner wall of the tongue groove 4 and the surface of the coupler 1, the overall buffering performance is enhanced and the wear of the parts is reduced. The motor 6 reduces the vibration through the top abutment plate 7 and spring 8, and improves the stability of the hook tongue 2. The abutment groove 9 fixes the extension end of the damper 39, which can greatly reduce the impact force. The locking block 10 prevents the limiting clip 36 from falling out. The mounting groove 11 fixes the damper 39 to ensure stable operation of the device and adapt to the complex working conditions of railway freight cars.
