Description

Technical Field

[0001] The utility model belongs to the technical field of track detection, and in particular relates to a mounting bracket for detecting vertical dynamic acceleration of a track. Background Art

[0002] Due to the frequent rolling pressure of trains and the changing seasons, the connections between the sleepers and the trackbed can loosen, resulting in a certain gap between the sleepers and the trackbed. During the passage of trains, the rails will drive the sleepers to move vertically, causing track unevenness during train operation, which can easily lead to safety accidents. Therefore, it is necessary to detect the degree of track unevenness and, based on the detection results, reduce the gap between the sleepers and the trackbed. Detection methods generally use vertical displacement sensors or radar detectors. Specifically, when using vertical displacement sensors, they need to be in direct contact with the sleepers or rails. This allows them to directly detect the vertical displacement of the sleepers or rails as they rise and fall. When using radar detectors, they need to be installed on the trackbed to directly detect the rise and fall of the rails or sleepers. However, with both methods, the vertical displacement sensors or radar detectors are difficult to install and secure, and the connection strength after installation is low. Over long periods of use, they are prone to shifting or becoming detached, ultimately affecting the detection results. Utility Model Content

The working principle and advantages of the present invention are as follows: the present invention is clamped on the sleeper by the sleeper clamp 200, thereby realizing an indirect connection between the universal adjustment seat 400 and the sleeper, and then the vertical displacement sensor is installed on the universal adjustment seat 400. In order to improve the accuracy of detection, multiple vertical displacement sensors are installed, and the data with large deviations are eliminated and the average value is taken; during the ups and downs of the sleeper, the vertical displacement sensor detects the unevenness of the track. The present invention is installed on the anchor seat on the track bed through the vertical connecting column 300. The anchor seat is generally a seat body cast on the track bed, and an anchor screw is anchored on the seat body.

The end of the clamping screw 205 abuts against the corresponding side of the sleeper, thereby achieving the purpose of fixing the fixing plate 201 to the sleeper. In order to adjust the clamping position and increase the clamping strength, this embodiment provides a first strip hole 204 extending in the vertical direction on the assembly ear 203, and the clamping screw 205 passes through the corresponding first strip hole 204.

The lower end of the vertical adjustment screw 406 is rotatably connected to the second connecting plate 405. An operating handwheel 407 is mounted on the upper end of the vertical adjustment screw 406. In this embodiment, rotating the operating handwheel 407 drives the vertical adjustment screw 406, thereby driving the vertical slide 404 along the vertical guide rail 401, thereby enabling the connecting base 408 on the vertical slide to drive the radar detector vertically. In this embodiment, a longitudinal screw 409 is constructed on the vertical slide 404, extending along the length of the track. The connecting base 408 is assembled on the longitudinal screw 409. A locking handwheel 410 is threadedly connected to the longitudinal screw 409 and tightened on the end surface of the connecting base 408 away from the vertical slide 404. When the downward tilt angle of the radar detector needs to be adjusted to align it with the detected position, the locking handwheel 410 is loosened, the connecting base 408 is rotated to a predetermined angle, and then the locking handwheel 410 is tightened. In order to adjust the horizontal deflection angle of the radar detector in this embodiment, a third connecting plate 403 is constructed at the lower end of the vertical guide rail 401, and a vertical fixing rod 413 is constructed at the lower end of the third connecting plate 403; a fixing block 411 is constructed on the longitudinal slide 412, which is assembled on the longitudinal guide rail 100, and a locking screw is threadedly connected to the longitudinal slide 412.

When the connection position of the longitudinal slide 412 and the longitudinal guide rail 100 needs to be adjusted, the locking screw is loosened, and then the relative position of the longitudinal slide 412 and the longitudinal guide rail 100 is adjusted. After completion, the locking screw is tightened. In this embodiment, the lower end of the vertical fixing rod 413 passes through the fixing block 411. A fastening nut 414 is threadedly connected to the vertical fixing rod 413 and tightened onto the lower end surface of the fixing block 411. By loosening the fastening nut 414, the vertical guide rail 401 can be rotated along the axis of the vertical fixing rod 413, thereby adjusting the horizontal deflection angle of the radar detector. After adjustment, the fastening nut 414 is tightened.

In this embodiment, the length of the connecting rod 501 inserted into the connecting tube 503 can be adjusted to adjust the spacing between the longitudinal plate 505 and the end of the sleeper, thereby adjusting the distance between the radar detector and the end of the sleeper. This allows for adjustment of the universal adjustment base 400, enabling the radar detector to accurately detect the heaving movement of the sleeper.
