Description

Technical Field

[0001] The utility model relates to the technical field of track inspection trolleys, in particular to a track inspection trolley with an anti-derailment function. Background Art

[0002] Track inspection trolley, full name track geometry detector, is a light track inspection equipment used to measure the geometry of railway tracks. It is mainly composed of a measuring trolley composed of gauge, level and other measuring devices, a body prism and an industrial computer, a high-precision total station, a wireless communication unit, etc., which can detect the internal and external geometry of railway tracks. Track inspection trolleys are widely used in high-speed railways, trams, subways, and ballasted railways with high design speeds.

[0003] At present, most of the existing track inspection carts have relatively simple functions. They only move the wheels of the cart by rotating. However, due to the long-term exposure of the track to the external environment, there may be lubricating stains such as oil and frost on its surface, which reduces the friction between the wheels and the track, causing the wheels to slip and the cart to overturn. Personnel are required to regularly check and clean the oil stains on the track, which increases the workload of the personnel and reduces the practicality of the track inspection cart. Therefore, we propose a track inspection cart with an anti-derailment function to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a track inspection trolley with an anti-derailment function, which solves the problem in the prior art that the existing tracks are exposed to the external environment for a long time and lubricating stains such as oil and frost may exist on their surfaces, which reduces the friction between the wheels and the tracks, causing the wheels to slip and the track inspection trolley to overturn, and personnel are required to regularly check and clean the oil stains on the tracks, which increases the workload of the personnel and reduces the practicality of the track inspection trolley.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0025] Furthermore, the tops of the two card blocks 8 are penetrated by jacks, and the two card blocks 8 are fixedly connected to the adjacent outer walls of the adjacent mounting boxes 2. Specifically, through the setting of the card blocks 8, the card blocks 8 can be connected to the mounting plate 7 through the card grooves, and the mounting plate 7, the side wheels 6 and the track 4 can be brought close to and positioned through the positioning components.

[0026] Furthermore, the positioning assembly includes a mounting shell 9 arranged on the top of the mounting plate 7, and the bottom of the mounting shell 9 is open, the bottom surface of the mounting shell 9 is fixedly connected to the top of the mounting plate 7, a limit plate 10 is provided inside the mounting shell 9, and a pull rod 12 is sleeved inside the limit plate 10, and the bottom end of the pull rod 12 passes through the top of the mounting plate 7 and is plugged into the socket and the slot. Specifically, through the setting of the pull rod 12, the pull rod 12 can be plugged into the socket in the block 8 and the slot in the slot through its bottom end, so that the pull rod 12 can position the block 8 and the mounting plate 7, thereby achieving a stabilizing effect between the mounting box 2 and the side wheel 6.

[0027] Furthermore, the positioning assembly also includes a pull block 11 arranged above the mounting shell 9, the top of the pull rod 12 passes through the top of the mounting shell 9 and is fixedly connected to the bottom of the pull block 11, the outside of the pull rod 12 and is located inside the mounting shell 9 and is provided with a spring 13, the two ends of the spring 13 are respectively fixedly connected to the top of the mounting shell 9 and the top of the limit plate 10. Specifically, through the setting of the spring 13, a person can hold the pull block 11 and pull the pull rod 12 upward to move, at which time the pull rod 12 moves upward and drives the limit plate 10 to move, and the limit plate 10 immediately squeezes the spring 13, and the pull rod 12 moves accordingly. That is, the personnel disengage from the slot, and then connect the slot on one side of the mounting plate 7 with the block 8 on one side of the mounting box 2, and then release the pull block 11 to make the spring 13 lose the extrusion force and elastically push the limit plate 10 back to its position and pull the pull rod 12 back to its position, so that the bottom end of the pull rod 12 is inserted into the socket in the block 8 and plugged into the slot at the bottom of the slot, thereby completing the positioning between the block 8 and the mounting plate 7, so that the side wheel 6 can be firmly fixed on the side wall of the track 4, providing side support for the wheel 5 in the mounting box 2, avoiding the trolley from slipping during operation, and improving the practicality of the track inspection trolley.

[0028] Furthermore, a limit groove is provided on one side of the top of the two mounting shells 9, a circular groove is provided on one side of the bottom of the two pulling blocks 11, a limit block 14 adapted to the limit groove is provided on the top of the mounting shell 9, and a plug rod 15 adapted to the circular groove is fixedly connected to the top of the limit block 14. Specifically, through the setting of the plug rod 15, when a person pulls the pulling block 11 to move upward, the person can move in the limit groove by toggling the limit block 14 and move it to the bottom of the circular groove, and then release the pulling block 11.

[0029] Furthermore, a control console 3 is fixedly installed on one side of the top of the installation box 2, and the adjacent side walls of the two installation boxes 2 are fixedly connected to the two sides of the support plate 1. Specifically, through the setting of the support plate 1, the support plate 1 can provide a stable supporting force between the two installation boxes 2, so that the track inspection trolley can run more stably.

[0030] In summary:

[0031] By holding the pull block 11 and pulling the pull rod 12 upward, the pull rod 12 moves upward and drives the limit plate 10 to move. The limit plate 10 immediately squeezes the spring 13, and the pull rod 12 immediately disengages from the inside of the slot. Then the personnel connects the slot on one side of the mounting plate 7 with the block 8 on one side of the mounting box 2, and then releases the pull block 11 to make the spring 13 lose the extrusion force and elastically push the limit plate 10 back and pull the pull rod 12 back, so that the bottom end of the pull rod 12 is inserted into the socket in the block 8 and plugged into the slot at the bottom of the slot, thereby completing the positioning between the block 8 and the mounting plate 7, so that the side wheel 6 can be firmly fixed on the side wall of the track 4, providing side support for the wheel 5 in the mounting box 2, avoiding the trolley from slipping during operation, and improving the practicality of the track inspection trolley.

[0032] When the personnel pulls the pull block 11 to move upward, the personnel can move in the limit groove and move to the bottom of the circular groove by toggling the limit block 14, and then release the pull block 11. When the pull block 11 falls, the top of the plug rod 15 will be plugged into the inside of the circular groove, thereby positioning the pull block 11 to prevent it from continuing to fall, so that the personnel can free their hands to operate another positioning component. There is no need for the personnel to keep pulling the pull block 11 for loading and unloading, which reduces the operating burden of the personnel and improves the practicality of the track inspection vehicle.
