An overhauling device

Abstract

This utility model discloses a maintenance device, including a vehicle body. A track gauge measuring sensor and an over-height measuring sensor are fixedly installed on the top of the vehicle body. A shaft cylinder is vertically fixedly installed at the center of the top of the vehicle body. A shaft cavity is opened at the top of the shaft cylinder. Several circular holes are opened through the shaft cavity on both opposite outer walls of the shaft cylinder. The circular holes are of the same size and evenly distributed. A shaft rod is slidably installed in the shaft cavity. Both circular shafts can penetrate and extend out of the outer wall of the shaft cylinder, thereby locking the shaft rod and fixing the relative installation height between the shaft rod and the shaft cylinder. This makes it more comfortable for workers of different heights and arm spans to use this track inspection trolley. Only a small part of the outer spherical wall of the rotating block is exposed and connected to an L-shaped curved rod, which allows the L-shaped curved rod to be adjusted at multiple angles within a certain range. This makes it convenient for the track inspection trolley to move on curved tracks without the need for the worker to tilt their body, thus ensuring that the track inspection trolley can be pushed.

Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a maintenance device. Background Technology

[0002] The track inspection trolley, also known as a track geometry condition detector, is mainly used in high-speed railways, trams, subways, and ballast railways with high design speeds.

[0003] This measuring device, consisting of a measuring trolley (comprised of gauge and level measuring instruments, a prism, and an industrial control computer), a high-precision total station, and a wireless communication unit, is used to detect the internal geometric state (gauge, level, alignment, elevation, positive and negative twist) and external geometric state (track centerline deviation, elevation deviation) of railway tracks. It is of great significance for the laying of high-speed railway track bed structures, the laying of long rails, the fine-tuning of long rails, and subsequent maintenance.

[0004] Track inspection trolleys are equipped with push handles to facilitate staff in moving and measuring the trolley on the track. However, the push handles of traditional track inspection trolleys are fixedly installed on the trolley seat. Staff of different heights and arm lengths may experience discomfort due to excessive arm bending angles when pushing the trolley. In addition, when moving and pushing the trolley on curved tracks, staff need to tilt their bodies to ensure that the direction of force applied to push the trolley is centered and does not deviate, which also reduces the user experience of the track inspection trolley. Utility Model Content

[0005] The purpose of this invention is to provide a maintenance device to solve the problem of inconvenient use.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A maintenance device includes a vehicle body. A track gauge sensor and an over-height sensor are fixedly installed on the top of the vehicle body. An axle cylinder is vertically fixedly installed at the center of the top of the vehicle body. An axle cavity is formed at the top of the axle cylinder. Several circular holes with the same size and evenly spaced are formed through the axle cavity on both opposite outer walls of the axle cylinder. A shaft rod is slidably installed in the axle cavity. A cavity is formed in the shaft rod. Two second fixed pulleys and two bushings are fixedly installed in the inner wall of the cavity. A main pull rope and two auxiliary pull ropes are also provided in the cavity. One end of the main pull rope is connected to the two auxiliary pull ropes. A round shaft is slidably installed in each of the two bushings. One end of each of the two round shafts extends out of the axle cylinder through a corresponding circular hole. Springs are fixedly installed at the ends of each of the two bushings. The two auxiliary pull ropes pass around the corresponding second fixed pulleys and pass through the corresponding springs to be fixedly connected to the corresponding round shafts.

[0008] As a further embodiment of this utility model: a multi-directional adjustment mechanism is fixedly installed at the top of the shaft, the multi-directional adjustment mechanism includes a mounting base, the mounting base is fixedly installed at the top of the shaft, a rotating block is rotatably installed inside the mounting base, and an L-shaped bent rod is fixedly installed at the top of the rotating block.

[0009] As a further embodiment of this utility model: a crossbar is vertically fixedly installed at the end of the L-shaped bent rod, and stop blocks are fixedly installed at both ends of the crossbar.

[0010] As a further embodiment of this utility model: a first fixed pulley is also fixedly installed in the inner wall of the cavity, one end of the main pull rope passes around the first fixed pulley and is connected to two auxiliary pull ropes, and the other end of the main pull rope extends through the shaft and is fixedly installed with a handle.

[0011] As a further embodiment of this utility model: the outer diameter of the two circular shafts is the same as the inner diameter of the bushing, and the other end of the two circular shafts is respectively set to abut against the corresponding spring.

[0012] As a further embodiment of this utility model: four mounting slots are provided at the bottom of the vehicle body, and rail wheels are rotatably mounted on the two opposite inner walls of the four mounting slots.

[0013] The beneficial effects of this utility model are:

[0014] First, a shaft cylinder is fixedly installed on the track inspection trolley. A shaft rod is slidably inserted into the shaft cylinder. Two round shafts are slidably installed on the two opposite outer walls of the shaft rod. Both round shafts can penetrate and extend out of the outer wall of the shaft cylinder, thereby locking the shaft rod in place and fixing the relative installation height between the shaft rod and the shaft cylinder. This makes it easier for staff of different heights and arm spans to use the track inspection trolley more comfortably.

[0015] Secondly, a mounting base is fixedly installed at the top of the shaft, and a rotating block is also installed inside the mounting base. Only a small part of the outer spherical wall of the rotating block is exposed and connected to an L-shaped curved rod. This allows the L-shaped curved rod to be adjusted to multiple angles within a certain range, so that when the track inspection trolley travels on a curved track, the staff no longer need to tilt their bodies to push the track inspection trolley.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Specific implementation examples are given below.

[0030] like Figure 1-5As shown, a maintenance device includes a vehicle body 1. A track gauge measuring sensor 2 and an over-height measuring sensor 3 are fixedly installed on the top of the vehicle body 1. Both the track gauge measuring sensor 2 and the over-height measuring sensor 3 are common track inspection sensors available on the market, and will not be described in detail here. A shaft cylinder 4 is vertically fixedly installed at the center of the top of the vehicle body 1. A shaft cavity 41 is opened at the top of the shaft cylinder 4. Several circular holes 42 are opened through the shaft cavity 41 on both opposite outer walls of the shaft cylinder 4. The circular holes 42 are of the same size and evenly spaced. A shaft rod 5 is slidably installed inside the shaft cavity 41. The cavity 5 has a cavity, in which two second fixed pulleys 54 and two bushings 55 are fixedly installed. The cavity also contains a main pull rope 52 and two auxiliary pull ropes 53. One end of the main pull rope 52 is connected to the two auxiliary pull ropes 53. A round shaft 56 is slidably installed in each of the two bushings 55. One end of each round shaft 56 extends through the corresponding round hole 42 to the outside of the shaft cylinder 4. A spring 57 is fixedly installed at the end of each of the two bushings 55. The two auxiliary pull ropes 53 pass around the corresponding second fixed pulley 54 and pass through the corresponding spring 57 to be fixedly connected to the corresponding round shaft 56.

[0031] like Figure 1-5 As shown, particularly noteworthy is that a multi-directional adjustment mechanism 6 is fixedly installed at the top of the shaft 5. The multi-directional adjustment mechanism 6 includes a mounting base 61, which is fixedly installed at the top of the shaft 5. A rotating block 62 is rotatably installed inside the mounting base 61. An L-shaped bent rod 63 is fixedly installed at the top of the rotating block 62. The bottom end of the L-shaped bent rod 63 extends through into the mounting base 61 and is fixedly installed on the rotating block 62. A crossbar 64 is vertically fixedly installed at the end of the L-shaped bent rod 63. Both ends of the crossbar 64 are fixedly fitted with stops to prevent slippage. A first fixed sliding block is also fixedly installed in the inner wall of the cavity. Wheel 51, one end of main pull rope 52 passes around the first fixed pulley 51 and connects to two auxiliary pull ropes 53 to change the direction of movement of main pull rope 52. The other end of main pull rope 52 extends through the shaft 5 and is fixedly installed with handle 58 to facilitate pulling main pull rope 52. The outer diameter of two round shafts 56 is the same as the inner diameter of bushing 55 to ensure that the round shafts 56 and bushing 55 are slidably installed stably without loosening. The other ends of the two round shafts 56 are respectively set to abut against the corresponding springs 57. Four mounting slots 11 are opened at the bottom of the vehicle body 1. Rail wheels 12 are rotatably installed on the two opposite inner walls of the four mounting slots 11.

[0032] The working principle of this utility model:

[0033] The first step is to adjust the height of the crossbar 64 according to the height and arm length of the staff using this trolley. The specific adjustment method is to pull the handle 58, which will pull the main pull rope 52 and the two auxiliary pull ropes 53, and then pull the corresponding round shafts 56 to retract from the corresponding round holes 42. At this time, both springs 57 will receive elastic restoring force. Then, pull the shaft 5 upward as a whole and release the handle 58. At this time, the two springs 57 will be released elastically due to the lack of pulling, and will push the corresponding round shafts 56 to slide in the corresponding bushings 55. However, at this time, the two round shafts 56 will abut against the inner wall of the shaft cavity 41 of the shaft cylinder 4 until the round shafts 56 slide to the corresponding round holes 42. At this time, the two round shafts 56 will be pushed into the corresponding round holes 42, and most of them will remain in the corresponding bushings 55. This completes the determination of the relative installation height of the shaft 5 and the shaft cylinder 4, which is to say, the adjustment of the height of the crossbar 64 is completed.

[0034] The second step is for the staff to hold the crossbar 64 with both hands and push it forward. At this time, the entire vehicle body 1 moves on the track. When the track bends, the staff still holds the crossbar 64 with both hands without turning their body. The rotating block 62 in the mounting base 61 will rotate automatically, so that the axle 5, the axle cylinder 4 and the vehicle body 1 can move forward normally. During the movement, the track gauge sensor 2 and the ultra-high measurement sensor 3 start to measure relevant data.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
