Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trackside equipment technology, specifically relating to a combined trackside equipment. Background Technology
[0002] According to the detection area, the combined trackside equipment is mainly divided into bottom detection unit, side detection unit, TCR antenna detection unit, top detection unit, vehicle speed measurement unit, and vehicle number image recognition unit. The vehicle speed measurement unit of the combined trackside equipment is used to monitor and transmit the operating status of the trackside equipment in real time, providing key data support for train control and track maintenance.
[0003] In the actual use of existing combined trackside equipment, the speed measuring unit uses a speed measuring device with a constant setting. If it is set at a curve of the track, it will not be able to match the curvature of the curve, which will easily lead to an excessive angle between the radar ultrasonic signal of the speed measuring device and the direction of vehicle movement, resulting in excessive measurement error and making it unsuitable for use.
[0004] Therefore, a combined trackside device is needed to solve the problem that most existing vehicle speed measurement units, when placed at curves in the track, cannot match the curvature of the curve, which easily leads to an excessively large angle between the radar ultrasonic signal of the speed measuring device and the direction of vehicle movement. Utility Model Content
[0005] The purpose of this invention is to provide a combined trackside device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined trackside device, including a column, a display screen fixed to one side of the column, a speed measuring device body disposed at one end of the column, and an adjustment mechanism acting on the speed measuring device body;
[0007] The adjustment mechanism includes a mounting base sleeved on the outside of the column, a vertical movement component acting on the mounting base, and a rotation component acting on the speed measuring device body. One side of the mounting base is fixed to the surface of the speed measuring device body.
[0008] It should be noted in the solution that the vertical moving component includes rod slots opened on both sides of the column, support seats slidably inserted into the inner cavity of the rod slots, threaded rods threadedly connected to one of the support seats, limiting rods slidably inserted into the other support seat, and a second motor fixed to the top of the column.
[0009] It is further worth noting that the top of the threaded rod passes through the column and is fixed to the output end of the second motor, the bottom of the threaded rod is rotatably connected to the inner wall of the adjacent position groove, the upper and lower ends of the limiting rod are fixed to the inner wall of the adjacent position groove, and the mounting base is slidably inserted into the two support bases.
[0010] Furthermore, it should be noted that the rotating assembly includes toothed blocks uniformly fixed to the inner circumferential surface of the mounting base, an opening in the inner cavity of one of the support bases near the mounting base, a first motor fixed to the top of one of the support bases, and a circular gear fixedly sleeved on the output end of the first motor extending into the inner cavity of the opening.
[0011] In a preferred embodiment, the output end of the first motor is rotatably connected to the bottom of the inner cavity surface of the opening, and the spur gear is meshed with a set of tooth blocks.
[0012] In a preferred embodiment, the adjustment mechanism further includes a protective component, which includes a connecting seat fixed to the bottom of the support base, a first spring telescopic rod fixed to both ends of the top of the connecting seat, and a support sleeve with a U-shaped cross-section fixed to the top of the first spring telescopic rod. The support sleeve and the mounting base are slidably inserted into each other.
[0013] In a preferred embodiment, the protective assembly further includes a second spring telescopic rod fixed to one end of the connecting seat and a contact plate fixed to one end of the second spring telescopic rod.
[0014] Compared with the prior art, the combined trackside device provided by this utility model has at least the following beneficial effects:
[0015] (1) The height of the speed measuring device can be adjusted by starting the support base. The speed measuring device can be adjusted in the horizontal direction by starting the first motor. Thus, by adjusting the position of the speed measuring device, the device can match the movement trajectory of the vehicle under the curvature of the curve when it is located at the curve of the track. This avoids the situation where the angle between the speed measuring device and the vehicle movement direction is too large, resulting in excessive measurement error, thereby improving the measurement accuracy.
[0016] (2) The first spring telescopic rod and the support sleeve can support the mounting base, thereby improving the stability of the mounting base during movement and reducing the sway amplitude of the mounting base under external force. The second spring telescopic rod and the contact plate set on both sides of the speed measuring body can limit the angle adjustment range of the speed measuring body in the horizontal direction to avoid collision with the support base, thereby improving the stability of the device operation.

Detailed Implementation
[0022] Please see Figure 1-4 This utility model provides a combined trackside device, including a column 1, a display screen 2 fixed to one side of the column 1, a speed measuring device body 3 disposed at one end of the column 1, and an adjustment mechanism acting on the speed measuring device body 3.
[0023] The adjustment mechanism includes a mounting base 4 sleeved on the outside of the column 1, a vertical movement component acting on the mounting base 4, and a rotation component acting on the speed measuring body 3. One side of the mounting base 4 is fixed to the surface of the speed measuring body 3.
[0024] When the column 1 is installed near the curve of the track, the display screen 2 can display the data measured by the speed measuring device 3. When the vehicle moves with the track, the height of the speed measuring device 3 and the mounting base 4 can be adjusted by the vertical movement component. The angle of the speed measuring device 3 in the horizontal direction can be adjusted by the rotation component. Thus, by adjusting the position of the speed measuring device 3, the device can match the movement trajectory of the vehicle under the curvature of the curve when it is located at the curve of the track, thereby avoiding the situation where the angle between the speed measuring device 3 and the direction of vehicle movement is too large, resulting in excessive measurement error.
[0025] Please see Figure 1-4The vertical moving assembly includes rod grooves 5 on both sides of the column 1, support seats 7 slidably inserted into the cavity of the rod grooves 5, threaded rods 6 threadedly connected to one of the support seats 7, limiting rods 8 slidably inserted into the other support seat 7, and a second motor 18 fixed to the top of the column 1. The top of the threaded rod 6 passes through the column 1 and is fixed to the output end of the second motor 18. The bottom of the threaded rod 6 is rotatably connected to the inner wall of the adjacent rod groove 5. The upper and lower ends of the limiting rod 8 are fixed to the inner wall of the adjacent rod groove 5. The mounting base 4 is slidably inserted into the two support seats 7.
[0026] By starting the second motor 18, the threaded rod 6 can rotate. Since the inner wall of the rod groove 5 can abut against the adjacent support seat 7, it can only move in the vertical direction. The limiting rod 8 can further limit the adjacent support seat 7, so that one of the support seats 7 can move in the vertical direction under the cooperation between the internal thread structure of its inner wall and the external thread structure of the threaded rod 6. Thus, under the abutment between the two support seats 7 and the mounting seat 4, the support seats 7 and the mounting seat 4 can move in the vertical direction, thereby adjusting the height position of the speed measuring device body 3.
[0027] Please see Figure 1-4 The rotating assembly includes toothed blocks 9 uniformly fixed to the inner circumferential surface of the mounting base 4, an opening 11 opened in the inner cavity of one of the support bases 7 near the mounting base 4, a first motor 10 fixed to the top of one of the support bases 7, and a circular gear 12 fixedly sleeved on the output end of the first motor 10 extending into the inner cavity of the opening 11. The output end of the first motor 10 is rotatably connected to the bottom of the inner cavity surface of the opening 11, and the circular gear 12 is meshed with a set of toothed blocks 9.
[0028] When the first motor 10 is started and the spur gear 12 rotates, the two support seats 7 limit the mounting seat 4, so that the mounting seat 4 can rotate under the meshing action of the spur gear 12 and a set of tooth blocks 9, thereby driving the speed measuring device body 3 to change angle in the horizontal direction, so that it can adapt to the vehicle's position change on the curve.
[0029] Please see Figure 1-4 The adjustment mechanism also includes a protective component, which includes a connecting seat 13 fixed to the bottom of the support seat 7, a first spring telescopic rod 14 fixed to both ends of the top of the connecting seat 13, and a support sleeve 15 with a U-shaped cross section fixed to the top of the first spring telescopic rod 14. The support sleeve 15 and the mounting seat 4 are slidably inserted into each other.
[0030] When the device is subjected to an external force that causes the mounting base 4 to vibrate, the support sleeve 15 is subjected to the vibration force, which causes the first spring telescopic rod 14 to deform. Under the action of the rebound force of the first spring telescopic rod 14, the swaying amplitude of the mounting base 4 is reduced, thereby improving the stability of the mounting base 4. Furthermore, due to the connection between the support sleeve 15 and the mounting base 4, the stability of the mounting base 4 during rotation is improved.
[0031] Please see Figure 1-4 The protective assembly also includes a second spring telescopic rod 16 fixed to one end of the connecting seat 13 and a contact plate 17 fixed to one end of the second spring telescopic rod 16.
[0032] When the speed measuring device body 3 rotates with the mounting base 4 and approaches the support base 7, it can abut against the contact plate 17, causing the second spring telescopic rod 16 at the adjacent position to deform. This reduces the impact force when the speed measuring device body 3 moves to both sides and prevents contact between the support base 7 and the speed measuring device body 3, thus improving the stability of the device.
