[0004] The above-mentioned mechanism realizes the shooting angle and real-time positioning of the device's adjustable camera through the mutual cooperation of various components. However, in actual use, since the inspection device needs to be installed on the train, after the angle is adjusted, it is necessary to ensure the stability after rotation to avoid the angle deviation of the inspection device caused by high-speed driving. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic inspection mechanism for high-speed railway contact network with non-destructive testing, so as to solve the problem proposed in the above-mentioned background technology that, since the inspection device needs to be installed on the train, after the angle is adjusted, it is necessary to ensure the stability after rotation to avoid the problem of angular deviation of the inspection device caused by high-speed driving.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed railway contact network automatic inspection mechanism for non-destructive testing, comprising a high-definition camera, the bottom end of which is snap-connected with a lifting plate, and the outer side of which is slidably connected with an installation box;

[0007] A driven gear is rotatably connected at the middle position of the bottom end of the high-definition camera, and a rotating mechanism for adjusting the angle of the high-definition camera is provided at the bottom end of the lifting plate, the rotating mechanism includes a driving gear, and the driving gear is meshed with one side of the driven gear, and the bottom end of the driving gear is fixedly connected to a driving motor, and the driving gear is provided inside the installation box;

[0011] Furthermore, the cross section of the limit block is in a "T" shape, and the limit block is slidably connected to the lifting plate.

[0012] Furthermore, one side of the limit block passes through the fixed block and extends to one side of the driven gear, and the driven gear and the limit block are in a snap-fit ​​connection.

[0013] Furthermore, the lifting mechanism includes a movable block, and the movable block is threadedly connected to the outer side of the threaded rod, the top end of the movable block is hinged with a hinge rod, and the top end of the hinge rod is hinged to the bottom end of the lifting plate.

[0015] 1. Adjust the shooting angle of the high-definition camera according to different inspection requirements. The output end of the driving motor drives the driving gear to rotate, so that the driving gear and the driven gear mesh with each other and drive the driven gear to rotate, so that the driven gear can drive the high-definition camera to change the angle, so that the high-definition camera can be flexibly adjusted according to different requirements.

[0018] 2. The threaded rod is driven to rotate by the rotation of the motor, so that the threaded rod is threadedly connected to the movable block, and the movable block is driven to move to one side. The movement of the movable block changes the angle of the hinged rod hinged on the top, thereby changing the height of the lifting plate set at the top of the hinged rod, which is convenient for adjusting the height of the high-definition camera according to different high-speed rail contact networks;

[0019] Furthermore, the movable block can move more smoothly through the slider and the slide rail during its movement. The movable block will drive the slider to move inside the slide rail when it moves, so that the angle of the movable block is limited to avoid angular deflection of the movable block.

[0032] Embodiment 2:

[0033] like Figure 2 , Figure 3 and Figure 5The technical solution shown is to solve the problem that the inspection device needs to be installed on the train and needs to ensure stability after rotation after angle adjustment to avoid the problem of angular deviation of the inspection device caused by high-speed driving: the high-speed railway contact network automatic inspection mechanism for non-destructive testing discloses a self-locking mechanism, a self-locking mechanism is provided on one side of the driven gear 4, the self-locking mechanism includes a fixed block 8, and the fixed block 8 is fixedly connected to the bottom end of the lifting plate 2, one end of the fixed block 8 is engaged and connected with a limit block 9, and one side of the limit block 9 is provided There is a cam 11, which is rotationally connected to the lifting plate 2.
