Description

Technical Field

[0001] The utility model relates to the technical field of sleeper spacing detection, in particular to a sleeper spacing detection device. Background Technique

[0002] Appropriate sleeper spacing is crucial for the stability and safety of the track. If the sleeper spacing is too large or too small, it will affect the load-bearing capacity of the track and the running smoothness of the train, increase the risk of track deformation and damage, and even may lead to serious accidents such as train derailment. By regularly detecting the sleeper spacing, abnormal spacing conditions can be detected in time, and corresponding maintenance measures can be taken to ensure track safety. Traditional sleeper spacing inspections often use manual measurement with a tape measure, which is time-consuming and laborious, and not convenient for recording. Content of the Utility Model

The distance between the two limit plates is adapted to the sleeper. The distance measurement assembly includes an infrared distance measurer, a support frame, a sliding plate, and a baffle. The infrared distance measurer is arranged on the bottom plate. The support frame is arranged above the infrared distance measurer. The sliding plate is slidably connected to the support frame. The baffle is arranged below the output end of the infrared distance measurer near the sliding plate. An anti-disengagement assembly is also arranged at one end of the sliding plate away from the baffle.

[0014] beneficial effects:

[0015] For this sleeper spacing detection device, the cooperation between the bottom plate and the limiting plate ensures the stable placement of the device on the track.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, A sleeper spacing detection device, comprising a support assembly, a ranging assembly and an anti - detachment assembly. The support assembly includes a bottom plate 1 and a limit plate 2. The limit plates 2 are symmetrically arranged on the front and rear sides below the bottom plate 1. The distance between the two groups of limit plates 2 is adapted to the sleeper. The ranging assembly includes an infrared rangefinder 3, a support frame 4, a slide plate 5 and a baffle 6. The infrared rangefinder 3 is arranged on the bottom plate 1, the support frame 4 is arranged above the infrared rangefinder 3, the slide plate 5 is slidably connected to the support frame 4, the baffle 6 is arranged below the output end of the infrared rangefinder 3 near the slide plate 5, and an anti - detachment assembly is also arranged at one end of the slide plate 5 away from the baffle 6.

[0023] The cooperation between the bottom plate 1 and the limit plate 2 ensures the stable placement of the device on the track. The distance between the two groups of limit plates 2 is adapted to the sleeper, enabling the device to be accurately positioned on the sleeper and not prone to lateral movement. The bottom plate 1 provides a stable basic support for the entire device, ensuring that the device does not shake during the measurement process. The slide plate 5 drives the baffle 6 to slide under the limitation of the support frame 4. The lower part of the baffle 6 is flush with the lower part of the limit plate 2, further enhancing the fit between the device and the sleeper and improving the stability during measurement. It should be noted that the infrared rangefinder 3 is connected to an external controller for data recording, which is convenient for control. According to requirements, the vertical and horizontal distance from the output end of the infrared rangefinder 3 to the nearest limit plate 2 is the thickness of the baffle 6, ensuring that the output value is the distance between the corresponding two groups of sleepers.

[0024] In this embodiment, an auxiliary plate 7 is further arranged at the end of the baffle 6 away from the output end of the infrared rangefinder 3. The bottom wall of the auxiliary plate 7 is flush with the bottom wall of the bottom plate 1, and the lower part of the baffle 6 is flush with the lower part of the limit plate 2, further enhancing the fit between the device and the sleeper and improving the stability during measurement. The setting of the auxiliary plate 7 increases the bearing area of the baffle 6, making the baffle 6 more stable when bearing the output pressure of the infrared rangefinder 3 or other external forces. The bottom wall of the auxiliary plate 7 is flush with the bottom wall of the bottom plate 1, ensuring the consistency of the entire device in the height direction and avoiding affecting the stability due to local unevenness.

[0025] During actual use, the anti - detachment assembly includes an elastic member and a block 8. Chutes are symmetrically arranged on the left and right sides of the slide plate 5. The two ends of the elastic member are respectively connected to the inner wall of the chute and the block 8. The block 8 protrudes from the slide plate 5. The block 8 is in a hemispherical shape. The elastic member includes a spring 9 and a telescopic rod 10. The spring 9 is sleeved on the telescopic rod 10. The two ends of the spring 9 and the telescopic rod 10 are respectively connected to the inner wall of the chute and the block 8. The slide plate 5 penetrates through the support frame 4. At this time, the block 8 protrudes from the slide plate 5, preventing the slide plate 5 from directly slipping out of the support frame 4. The spring 9 facilitates the reciprocating movement of the block 8, and the telescopic rod 10 ensures the stability of the movement of the block 8.
