Description

Technical Field

[0001] This utility model relates to the field of lateral movement limiting technology for tamping machines, and in particular to a lateral movement limiting mechanism for tamping machines. Background Technology

[0002] Continuous tamping stabilizers enable continuous three-sleeper tamping operations, ensuring the main trolley travels at a constant speed while the tamping device lowers to compact the track ballast. However, during operation, various factors can cause the tamping stabilizer's satellite trolley to fail to maintain alignment with the main trolley, resulting in deviation from the rails. This can lead to the tamping device lowering and damaging the rails, causing bending of the leveling rods, and affecting track quality. In such cases, a lateral movement limiting mechanism for the tamping stabilizer is required. This mechanism consists of a sensor switch and an electrical control box. When the sensor switch detects that the satellite trolley has failed to maintain alignment with the main trolley and is moving laterally, it sends a signal to the electrical control box. The electrical control box then cuts off the operation of the tamping device, thus limiting the lateral movement of the satellite trolley. When the tamping car lateral movement limit mechanism is working, the inductive switch is located at the bottom of the tamping car and close to the railway subgrade. Therefore, oil and debris are easily attached to the inductive switch during operation, which will affect the normal monitoring of the inductive switch and make it difficult to laterally limit the satellite trolley in time. Ultimately, this can easily cause the tamping device to insert and damage the rail and cause the leveling rod to bend. Utility Model Content

[0003] The main purpose of this utility model is to provide a lateral movement limiting mechanism for a tamping machine, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A lateral movement limiting mechanism for a tamping machine includes a mounting bracket and a sensor switch. The sensor switch is fixedly mounted on the mounting bracket. A resistance-increasing structure is movably mounted on the mounting bracket. The resistance-increasing structure consists of a square rod, an anti-detachment plate, a spring, and a slider. The anti-detachment plate and the slider are respectively fixedly mounted at both ends of the square rod. The spring is sleeved on the square rod. A protective structure is movably mounted on the resistance-increasing structure. The protective structure is also sleeved on the outside of the sensor switch. The protective structure consists of an arc-shaped plate, a support plate, and a connecting plate. There are two support plates, which are symmetrically fixedly mounted on the inner wall of the arc-shaped plate. The connecting plate is fixedly mounted at one end of the two support plates.

[0006] Preferably, the mounting bracket consists of a fixing plate and clamping blocks. There are two clamping blocks, and the two clamping blocks are fixed together by bolts. The clamping blocks are also fixed to one end of the fixing plate by bolts. Two mounting through slots are symmetrically opened on the fixing plate. Two embedded guide rail slots are symmetrically opened on one end of the fixing plate and on both sides of the mounting through slots. A connecting guide rail slot is opened on the other end of the fixing plate, and the embedded guide rail slot and the connecting guide rail slot are interconnected.

[0007] Preferably, the fixing plate is fixedly installed on one end of the satellite trolley crossbeam by bolts, and a protective frame is fitted on the satellite trolley crossbeam. An induction iron plate is fixedly installed on one end of the protective frame near the mounting bracket.

[0008] Preferably, the inductive switch is clamped and fixed by two clamping blocks, and the inductive switch is directly facing the inductive iron plate.

[0009] Preferably, the slider on the resistance-increasing structure is slidably mounted in the embedded guide rail groove, the square rod is slidably mounted in the connecting guide rail groove, and the spring and anti-detachment plate are located on one side of the fixed plate.

[0010] Preferably, the arc-shaped plate on the protective structure is sleeved on the outside of the inductive switch, the connecting plate has a square hole, the connecting plate is movably sleeved on the square rod through the square hole, and the connecting plate is simultaneously located between the fixed plate and the spring.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a protective structure, the inductive switch can be protected, thereby reducing the probability of oil and debris adhering to the inductive switch, ensuring that the inductive switch can monitor normally, and ultimately enabling the tamping trolley lateral movement limit mechanism to timely limit the lateral movement of the satellite trolley. By sliding a resistance-increasing structure on the mounting bracket and setting the protective structure on the resistance-increasing structure, the position of the protective structure can be adjusted according to the position of the inductive switch. At the same time, under the elastic force of the spring on the resistance-increasing structure, there is a large friction between the protective structure and the mounting bracket when no movement is required, making the protective structure less likely to move accidentally due to external forces.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 - Figure 5As shown, a tamping machine lateral movement limiting mechanism includes a mounting bracket 1 and a sensor switch 2. The sensor switch 2 is fixedly mounted on the mounting bracket 1. A resistance-increasing structure 3 is movably mounted on the mounting bracket 1. The resistance-increasing structure 3 consists of a square rod 12, an anti-detachment plate 13, a spring 14, and a slider 15. The anti-detachment plate 13 and the slider 15 are respectively fixedly mounted at both ends of the square rod 12. The spring 14 is sleeved on the square rod 12. A protective structure 4 is movably mounted on the resistance-increasing structure 3. The protective structure 4 is also sleeved on the outside of the sensor switch 2. The protective structure 4 consists of an arc-shaped plate 16, a support plate 17, and a connecting plate 18. There are two support plates 17, which are symmetrically fixedly mounted on the inner wall of the arc-shaped plate 16. The connecting plate 18 is fixedly mounted on one end of the two support plates 17. The mounting bracket 1 consists of a fixing plate 20 and clamping blocks 11. There are two clamping blocks 11, and the two clamping blocks 11 are fixedly mounted together by bolts. The clamping blocks 11 are also fixedly mounted on one end of the fixing plate 20 by bolts. Two mounting slots 8 are symmetrically provided on the fixing plate 20. Two embedded guide rail slots 9 are symmetrically provided on one end of the fixing plate 20 and on both sides of the mounting slots 8. A connecting guide rail slot 10 is provided on the other end of the fixing plate 20, and the embedded guide rail slots 9 and the connecting guide rail slots 10 are interconnected. The fixing plate 20 is fixedly installed on one end of the satellite trolley crossbeam 5 by bolts. A protective frame 6 is fitted on the satellite trolley crossbeam 5. An induction iron piece 7 is fixedly installed on the end of the protective frame 6 near the mounting bracket 1. The induction switch 2 is clamped and fixed by two clamping blocks 11, and the induction switch 2 is directly facing the induction iron piece 7. In use, the induction switch 2 determines whether the satellite trolley has moved laterally by sensing the position of the induction iron piece 7 on the protective frame 6. When the induction switch 2 detects that the satellite trolley has moved laterally, it will send a signal to the electrical control box, and the electrical control box will cut off the operation of the tamping device, thereby limiting the lateral movement of the satellite trolley and preventing the tamping device from inserting and damaging the rails and bending the leveling rod.

[0021] Ultimately, by setting up the protective structure 4, the inductive switch 2 can be protected, thereby reducing the probability of oil and debris adhering to the inductive switch 2, and ensuring that the inductive switch 2 can monitor normally. This allows the tamping trolley lateral movement limit mechanism to timely limit the lateral movement of the satellite trolley. By sliding the resistance-increasing structure 3 on the mounting bracket 1 and setting the protective structure 4 on the resistance-increasing structure 3, the protective structure 4 can be adjusted according to the position of the inductive switch 2. At the same time, under the elastic force of the spring 14 on the resistance-increasing structure 3, the protective structure 4 can have a large frictional force with the mounting bracket 1 when it does not need to move, making the protective structure 4 less likely to move accidentally due to external forces.

[0022] Specifically, the slider 15 on the resistance-increasing structure 3 is slidably installed in the embedded guide rail groove 9, the square rod 12 is slidably installed in the connecting guide rail groove 10, the spring 14 and the anti-detachment plate 13 are located on one side of the fixed plate 20, the arc plate 16 on the protective structure 4 is sleeved on the outside of the inductive switch 2, and the connecting plate 18 has a square hole 19. The connecting plate 18 is movably sleeved on the square rod 12 through the square hole 19, and the connecting plate 18 is simultaneously located between the fixed plate 20 and the spring 14. When it is necessary to adjust the position of the protective structure 4 so that the arc plate 16 on the protective structure 4 can better protect the inductive switch 2, the protective structure 4 and the resistance-increasing structure 3 can be slid directly on the fixed plate 20 on the mounting bracket 1. After the arc plate 16 completely blocks the inductive switch 2, the movement of the protective structure 4 and the resistance-increasing structure 3 can be stopped.
