Description

Technical Field

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

[0002] Sleepers are an important part laid on railways to support the tracks and are very important components in the entire railway.

[0003] On the operating lines of ballasted railways, due to reasons such as wheel-rail action, different longitudinal forces on the left and right rails, and different ballast reactions on the sides of sleepers in different positions, after long-term use, the sleepers often show uneven spacing or skewing. Among them, the sleeper spacing and the sleeper inclination are important indicators for the later inspection of sleepers, used to evaluate the quality of sleepers. Therefore, it is necessary for staff to inspect the sleepers to ensure that the sleepers are horizontal and the distance between adjacent two sleeper brackets is consistent.

[0004] Usually, a steel ruler is used to measure the sleeper spacing, and a square ruler is used to measure the sleeper inclination. However, during the inspection of the sleeper spacing and inclination by the above methods, the efficiency is low, which brings great trouble to track maintenance personnel.

[0005] Chinese Patent CN202322269553.4 discloses "A Sleeper Detection Device for Railway Maintenance", with the publication number CN220625092U. The device includes a rail, and sleepers are installed at the bottom of the rail. A vertical block is provided on one side of the rail, and two clamping plates are provided in front of the vertical block. The rear end of the upper clamping plate is fixedly connected to the upper part of the front end face of the vertical block. However, this device has some defects: the device is fixed on the railway track by clamping plates. Since the surface of the railway track is smooth, under the action of external forces, the device is very easy to slip off the railway track. Moreover, the number of sleeper measurements is large, and the disassembly and installation steps need to be repeated, which brings additional work to the staff. In addition, the distance between the lower surface of the railway track and the ballast is very close. When clamping the railway track with clamping plates, it is necessary to clean the ballast under the railway track first before it can be clamped. Summary of the Utility Model

[0006] In order to solve the above problems of the prior art, the utility model provides a sleeper spacing detection device for railway maintenance, which can move on the track, does not need to fix the device on the track, and can accurately measure the sleeper spacing.

[0007] To achieve the above object, the utility model provides the following technical solution: A sleeper spacing detection device for railway maintenance, including a reference plate, a fitting rod is vertically penetrated and attached to the front end of the reference plate, a positioning rod capable of linear movement is arranged at the rear end of the reference plate, the positioning rod is threaded through a fixing plate, and the fixing plate is fixedly connected to the reference plate; a vehicle axle is rotatably connected to the reference plate, and wheels matching the rails are fixedly connected to the vehicle axle.

[0011] Preferably, the positioning rod penetrates through the pointing plate, and snap rings are tightly sleeved on the positioning rod, and the snap rings are symmetrically arranged on both sides of the pointing plate.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 . The present utility model provides a technical solution: a sleeper spacing detection device for railway maintenance, including a reference plate 1. Two groups of the reference plates 1 are provided. A fitting rod 11 is vertically penetrated and attached to the front end of the reference plate 1. A positioning rod 2 capable of linear movement is arranged at the rear end of the reference plate 1. The positioning rod 2 is threaded through a fixing plate 21, and the fixing plate 21 is fixedly connected to the reference plate 1. A hand wheel 46 is fixedly connected to the front end of the positioning rod 2 for the staff to rotate the positioning rod 2. A car axle 3 is rotatably connected to the reference plate 1, and wheels 39 matching the railway tracks are fixedly connected to the car axle 3.

[0026] The fitting rod 11 is covered with external threads, and the lower end of the fitting rod 11 has no threads. Rotate the fitting rod 11 so that the lower end of the fitting rod 11 can be attached to the front sleeper. Rotate the fitting rod 11 in the reverse direction so that the fitting rod 11 moves above the sleeper to prevent the fitting rod from interfering with the movement of this device.

[0027] One end of the positioning rod 2 is rotatably connected to a pointing plate 4. A guide rod 41 is penetrated through the pointing plate 4. The guide rod 41 is fixedly connected to a slider 42. The slider 42 is slidably connected to a circular slide rail 43 matching it. The circular slide rail 43 is fixedly connected to the fixing plate 21. The center of the circular slide rail 43 and the circle of the positioning rod 2 are on the same axis.

[0028] Scales are engraved along the length direction of the guide rod. The starting point of the scales is in the same vertical plane as the edge of the rear end of the reference plate 1, and the starting value of the scales is the width value of the reference plate 1. When the pointing plate 4 moves, the pointing plate 4 fits against the sleeper, and the scale value where the pointing plate 4 is located at this time is the sleeper spacing value.

[0029] The positioning rod 2 passes through the pointing plate 4, and a clamping ring 45 is fixedly sleeved on the positioning rod 2. The clamping rings 45 are symmetrically arranged on both sides of the pointing plate 4.

[0030] The axle 3 includes a rotating shaft 31 rotatably connected to the reference plate 1, an extension cylinder 32 sleeved on the rotating shaft 31, and a positioning bolt 33 vertically passing through the extension cylinder 32. The wheel 39 is fixedly connected to the rotating shaft 31, and a through hole matching the positioning bolt 33 is opened on the rotating shaft 31.

[0031] When measuring the sleeper spacing with this device, the staff first rotates the fitting rod 11 so that the lower end of the fitting rod 11 can fit against the front sleeper. Next, the staff rotates the positioning rod 2, and the positioning rod 2 drives the pointing plate 4 to move towards the rear sleeper until the lower end of the pointing plate 4 fits against the edge of the rear sleeper. The value on the guide rod 41 where the pointing plate 4 is located at this time is the sleeper spacing value;

[0032] When moving this device, the staff first slightly rotates the positioning rod 2 backward, and then the staff moves the slider 42. The guide rod 41 drives the pointing plate 4 to perform a circular motion, which can change the pointing plate 4 from vertical to horizontal. Then the staff rotates the fitting rod 11 backward to move the fitting rod 11 above the sleeper, so that the fitting rod does not interfere with the movement of this device and prevent this device from colliding with the sleeper during movement.
