Technical Field
[0001] This utility model relates to the field of railway maintenance technology, and in particular to a track inspection device for railway maintenance and repair. Background Technology
[0002] Railways are a crucial transportation infrastructure. The track, including steel rails, sleepers, ballast, and turnouts, is the foundation for train operation. The roadbed supports the weight of the track and train. Bridges cross obstacles, and tunnels pass through mountains or underground to ensure the continuity of the line. The communication and signaling system is responsible for information transmission and train operation command. The power supply system provides power to electrified railway trains. During railway maintenance and repair, track inspection devices, such as track inspection trolleys, are often used to inspect the track.
[0003] In daily work, it has been found that existing track inspection devices are typically moved along the guide rail for inspection. However, when the device needs to be temporarily parked or parked for inspection, it is inconvenient to position it on the track, which can cause changes in the relative position between the inspection probe and the track. Since the detection accuracy of track geometric parameters such as gauge, level, and elevation is highly dependent on the relative position between the inspection probe and the track, once this position deviates, the obtained data cannot accurately reflect the true condition of the track, seriously affecting the reliability of the inspection results. Utility Model Content

Therefore, this invention proposes a track testing device for railway maintenance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a track inspection device for railway maintenance, comprising two guide rail bodies, a track inspection trolley disposed above the guide rail bodies, a handle fixedly connected to the surface of the track inspection trolley, an instrument placement plate fixedly connected to the surface of the handle, an inclination sensor disposed on the inner wall of the track inspection trolley, a target prism disposed on the surface of the track inspection trolley, and a stabilizing device disposed on the surface of the track inspection trolley, the stabilizing device comprising two fixing frames, the two fixing frames being respectively fixed to the two side surfaces of the track inspection trolley. The connection includes a sliding sleeve slidably connected to the inner wall of the fixed frame, a clamping rod slidably connected to the inner wall of the sliding sleeve, a positioning adjustment part between the sliding sleeve and the clamping rod, and a telescopic rod fixedly connected to the inner wall of the fixed frame. The output end of the telescopic rod passes through the fixed frame and is fixedly connected to the surface of the sliding sleeve. Through the above components, when the track inspection trolley is performing a zero-stop or stop inspection, the track inspection trolley is first stopped, and then the telescopic rod is opened. The telescopic rod drives the sliding sleeve and the clamping rod to move, so that the clamping rod is clamped on the surface of the guide rail, thereby realizing the positioning operation and improving the inspection accuracy.
[0006] Preferably, the clamping rod is T-shaped.
[0007] Preferably, an anti-slip pad is fixedly connected to the surface of the clamping rod. The anti-slip pad is made of rubber and has multiple anti-slip grooves on its surface. Through the above components, the clamping rod and the anti-slip pad can better fit with the guide rail, increasing friction and reducing damage to the guide rail.
[0008] Preferably, the positioning adjustment part includes a threaded seat fixed on the surface of the sliding sleeve, and a positioning screw is threadedly connected to the inner wall of the threaded seat. Two positioning holes are opened on the surface of the clamping rod, and the positioning screw is inserted into the inner wall of the positioning hole. Through the above components, the positioning screw is inserted into the corresponding positioning hole, which facilitates the positioning of the clamping rod in different positions and facilitates subsequent storage.
[0009] Preferably, the surface of the instrument placement plate is provided with a protective device. The protective device includes a plate body located above the instrument placement plate. Four sliding rods are fixedly connected to the surface of the plate body. The sliding rods are slidably connected to the inner wall of the instrument placement plate. A buffer spring is sleeved on the surface of the sliding rod. The two ends of the buffer spring are fixedly connected to the surface of the instrument placement plate and the plate body, respectively. A clamping part is provided on the surface of the plate body. Through the above components, the notebook can be clamped on the plate body through the clamping part. During the movement and testing process, when subjected to vibration, the buffer spring can play a certain protective and buffering role.
[0010] Preferably, the clamping part includes two clamping blocks that are slidably connected to the inner wall of the plate. A transmission screw is rotatably connected to the inner wall of the plate. The transmission screw is threadedly connected to the inner wall of the two clamping blocks. By rotating the transmission screw through the above components, the transmission screw can drive the clamping blocks to move, thereby clamping and fixing the computer.
[0011] Preferably, the surface of the clamping block has a rectangular hole, which facilitates the insertion of connecting wires and connection to a computer.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting a stabilizing device, after the positioning adjustment part is adjusted and positioned in the sliding sleeve by clamping rod, two sets of telescopic rods push the clamping rod to hold the guide rail, ensuring that the detection device is placed stably, reducing the change in the relative position of the detection probe and the track due to displacement caused by external force, ensuring the accuracy of detection of geometric parameters such as track gauge and level, and providing a reliable basis for track condition assessment.
[0014] In this invention, by setting up a protective device, the buffer spring can cause the buffer plate to move up and down when vibration is detected during movement, thus protecting the placed computer; the clamping part can firmly clamp the equipment by driving the clamping block through the transmission screw.

The output end of the telescopic rod 73 passes through the fixed frame 71 and is fixedly connected to the surface of the sliding sleeve 74.
[0024] In this embodiment: when the track inspection trolley 2 is performing a temporary stop or a stop inspection, the track inspection trolley 2 is first stopped, and then the telescopic rod 73 is opened. The telescopic rod 73 drives the sliding sleeve 74 and the clamping rod 72 to move, so that the clamping rod 72 is clamped on the surface of the guide rail body 1, thereby realizing the positioning operation and improving the detection accuracy.
[0025] Specifically, the clamp 72 is configured in a "T" shape.
[0026] Specifically, the surface of the clamping rod 72 is fixedly connected with an anti-slip pad 77, which is made of rubber and has multiple anti-slip grooves on its surface. The clamping rod 72, together with the anti-slip pad 77, can better fit with the guide rail 1, increasing friction and reducing damage to the guide rail 1.
[0027] Specifically, the positioning adjustment part includes a threaded seat 76 fixed on the surface of the sliding sleeve 74.
