[0001] The utility model belongs to the technical field of rail transit tunnel detection, and in particular relates to a portable bracket for rail detection. Background Art

[0002] In order to ensure the normal operation of rail transit, it is necessary to inspect the tunnels through which rail transit passes, and the upper wall of the tunnel needs to be inspected by geological radar. During the inspection, the radar antenna needs to be in close contact with the upper wall of the tunnel. In the prior art, during the inspection, the inspectors need to stand on the scaffolding to fit the radar antenna with the upper wall of the tunnel for inspection, and then the scaffolding is moved to achieve the inspection. During the inspection process, since the scaffolding needs to be kept in close contact with the upper wall of the tunnel, the inspectors cannot hold the scaffolding by hand when it moves. The whole process is prone to safety issues for the inspectors, and in order to ensure the installation of the inspectors, the moving speed of the scaffolding is uneven, which affects the quality of the inspection data and the efficiency of the inspection work.

[0012] Beneficial effects of the utility model:

[0013] 1) The structure is simple. The support assembly can keep the radar antenna in contact with the upper wall of the tunnel. The mobile base can also drive the support assembly and the radar antenna to move in the tunnel. During use, the detection personnel only need to move along the track with the device. Therefore, it can effectively solve the safety problem of standing on the scaffolding when the geological radar detects the upper wall of the tunnel.

[0014] 2) When moving, the mobile base can be moved directly on the track surface without considering the safety of the inspectors. Therefore, the moving speed can be more uniform, thereby improving the inspection efficiency and data quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0019] like Figure 1-2 As shown, a portable bracket for track detection is mainly composed of a mobile base and a supporting assembly, wherein the supporting assembly is arranged on the mobile base, and the mobile base can move along the track with the supporting assembly, and the supporting assembly is used for the installation of the radar antenna and has the functions of rotation and extension.

[0020] The specific structure of the mobile base includes a mounting base 1, below which four running wheels that can move on the track are distributed in a rectangular shape, wherein the running wheels adopt universal wheels with locking functions in the prior art, or use running wheels with built-in running motors.

[0021] The mounting base includes a rectangular frame 1a, and a support mounting rod 1b for mounting the support assembly is arranged in the middle of the rectangular frame 1a. To ensure the overall strength, reinforcing ribs 1c for ensuring strength are arranged between the upper and lower ends of the support mounting rod 1b and the rectangular frame 1a, and the reinforcing ribs at the upper and lower ends of the support mounting rod 1b are staggered. In this embodiment, four reinforcing ribs are arranged at the upper and lower ends of the support mounting rod.

[0022] In order to facilitate the overall movement, a push rod or a pull rod is also equipped. At the same time, a movable installation rod 1d is provided on the rectangular frame 1a for easy installation of the push rod or the pull rod. Of course, the movable installation rod can be welded to the rectangular frame, or fixed by bolts, rivets, etc., or can be hinged to the rectangular frame.

[0023] The support assembly includes a first support rod 2 vertically arranged on a movable base, a second support rod 3 is tiltedly arranged on the upper end of the first support rod 2 through a rotatable assembly, and a third support rod 4 is arranged on the second support rod 3 through a mounting structure.

[0024] The rotating assembly includes an articulated seat 5 arranged at the upper end of the first support rod 2, and reinforcing ribs are also arranged between the articulated seat and the first support rod. A hinge shaft 6 passing through the lower end of the second support rod 3 is rotatably arranged on the articulated seat 5, that is, the first support rod and the second support rod are connected by a hinge, and of course, rotation can also be achieved through a universal joint. The above methods are all manual adjustment, and electric adjustment methods driven by a motor or a telescopic cylinder can also be adopted, such as existing structures such as a bevel gear combination or a screw nut combination.

[0025] The mounting structure includes a plurality of mounting holes arranged at the upper end of the second support rod 3 or the lower end of the third support rod 4, and a bolt assembly is provided in any mounting hole. Of course, the plurality of mounting holes can also be a strip hole. In this case, telescopic adjustment can be achieved by setting on different mounting holes. Of course, the telescopic adjustment can also be a telescopic rod structure, and the telescopic rod can be automatically adjusted or manually adjusted.
