Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail detection, in particular to a railway track spacing detection device. Background Art
[0002] As a vital means of transportation, the operational safety of the railway system is closely linked to the precision of its track structure. Track spacing, one of the most critical parameters of track geometry, refers to the vertical distance between the inner working edges of the rail heads of two rails. Maintaining track gauge within strict design limits is crucial for ensuring smooth train operation, preventing abnormal wheel and rail wear, and even avoiding derailment accidents.
[0003] Existing automated track gauge detection equipment, such as laser detection devices, are typically mounted on track inspection vehicles or hand-pushed inspection instruments. Their operating principle generally relies on high-precision sensors to perform non-contact measurements of the working edge of the rail. These devices enable continuous track gauge data collection, significantly improving detection efficiency and accuracy. However, in actual use, trains travel at excessive speeds, and small stones and debris are easily swept up by the speed and fall onto the track surface. When the vehicle carrying the track gauge detection equipment travels on the track surface, the wheels roll over the stones or debris scattered on the track surface, inevitably generating instantaneous impact and vibration, causing the entire detection equipment to vibrate. This vibration is particularly significant for high-precision track gauge measurement systems and can easily affect detection accuracy. Therefore, a railway track spacing detection device is proposed to address the above-mentioned problem. Utility Model Content

[0038] Reference Figure 1-Figure 3 The telescopic mechanism includes two sleeves 24, which are respectively fixedly connected to the inner walls of the two mounting frames 1. The middle parts of the two sleeves 24 are slidably connected with pull rods 26, one end of the two pull rods 26 is fixedly connected with a block 25, and the other ends of the two pull rods 26 are respectively connected to the two slides 2. The outer periphery of the two pull rods 26 is sleeved with compression springs 36, and the opposite sides of the two slides 2 are respectively installed with a locking assembly, which includes two rotating plates 28. The two rotating plates 28 are respectively rotatably connected to the opposite sides of the two slides 2, and the middle parts of the rotating plates 28 are fixedly connected with insertion rods 29. The opposite sides of the two mounting frames 1 are provided with insertion holes 27, and the compression springs 36 are located in the middle of the sleeve 24. During the installation process of the device and the rail, the slide plate 2 is pulled to drive the pull rod 26 to slide in the middle of the sleeve 24. At the same time, the pull rod 26 drives the block 25 to squeeze the compression spring 36 in the sleeve 24. After the slide plate 2 is pulled open, the rotating plate 28 is rotated, and the insertion rod 29 is inserted into the insertion hole 27, so that the mounting frame 1 and the slide plate 2 are unfolded, and then one group of mounting frames 1 and slide plates 2 are placed on the rail, and the sliding rod 15 is pulled out of the shell 14, and another group of mounting frames 1 and slide plates 2 are placed on the rail at the other end.

After the device is set up on the rail, the electric push rod 17 is driven to retract and pull the connecting arm 31, so that the connecting arm 31 drives the diagonal brace 21 to rotate in the middle of the connecting base 30 through the connecting block 32, so that the diagonal brace 21 can fit the support wheel 18 into the rail surface, thereby auxiliary supporting the device through the support wheel 18, and the stability of the device during movement is improved under the action of the triangular structure.
[0040] Working principle: During the movement of the device, the air pump 8 is driven in connection with the shunt pipe 9, the telescopic pipe 10 and the connecting pipe 11, so that the nozzle 7 can blow air to the rail surface, thereby cleaning the pebbles and other fallen leaves and branches on the rail surface. At the same time, the servo motor 12 is driven to drive the brush 13 to rotate in the middle of the support frame 6. The rotation direction of the brush 13 is opposite to the rotation direction of the rotating wheel 4 and the rotating roller 23 during the movement, thereby further cleaning the debris on the rail surface and avoiding bumps during the equipment detection process.
[0041] Pulling the slide 2 drives the pull rod 26 to slide in the middle of the sleeve 24 and squeeze the compression spring 36, so that the mounting frame 1 and the slide 2 can be quickly placed on both sides of the rail. After releasing the slide 2, the compression spring 36 pushes the block 25 to pull the pull rod 26, so that the pull rod 26 drives the slide 2 to reset, so that the rotating wheels 4 in the mounting frame 1 and the slide 2 can clamp the rail, thereby improving the installation efficiency of the device and the rail.
[0042] After the mounting frame 1 and the slide plate 2 are clamped on the rail, the electric push rod 17 is driven to retract and pull the connecting arm 31, so that the connecting arm 31 pulls the diagonal support 21 to rotate in the middle of the connecting seat 30 through the connecting block 32, so that the diagonal support 21 can place the support wheel 18 on the rail surface and form a triangular structure, thereby improving the stability of the movement of the device.
