[0016] The following will be combined with the attached embodiment of the present utility model Figure 1 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0017] Example 1

[0018] This embodiment provides a portable positioning tool for GIS ray detection, which can accurately set the height position of the X-ray machine and the imaging plate, improve the detection accuracy, and reduce the labor intensity of the staff. The positioning tool includes a mobile platform 1 that is easy to move, a telescopic sleeve rod 4 that can change the height, and a placement table 6 for placing the ray detection equipment. The placement table 6 is fixed to the top of the telescopic sleeve rod 4. By adjusting the height of the telescopic sleeve rod 4, the height position of the ray detection equipment on the placement table 6 can be controlled to improve the detection accuracy. The telescopic sleeve rod 4 is fixed to the mobile platform 1 to facilitate the movement of the entire device.

[0019] In this embodiment, the mobile platform 1 is a cart with walking wheels. The telescopic sleeve 4 includes a sleeve 401 and a lifting rod 402 slidably arranged in the sleeve 401. The placement platform 6 is arranged on the top of the lifting rod 402, and the sleeve 401 is vertically arranged on the upper end surface of the mobile platform 1.

[0020] In order to adjust the height of the telescopic sleeve rod 4, a long hole 403 is provided on the peripheral side of the sleeve 401 along its radial direction, and a slider 404 is provided at the lower end of the lifting rod 402, which is slidably arranged in the long hole 403. The upper part of the sleeve 401 is fixed with a hoist 5 through a fixed platform 9, and the hoist 5 is fixed on the upper part of the sleeve 401. The rope of the hoist 5 is connected to the slider 404. By starting the hoist 5 and winding the rope, the slider 404 can be controlled to rise. The rise of the slider 404 brings the placement table 6 on the lifting rod 402 up, so that the radiation detection equipment on the placement table 6 is at a specified height, improving the accuracy of the detection. At the same time, the hoist 5 controls the placement table 6 to greatly reduce the work intensity of the staff. It should be noted here that the hoist 5 is a prior art device, and its control and power supply are both prior art, and the functions described by those skilled in the art shall prevail.

[0021] In order to reduce the load of the telescopic sleeve rod 4 in this embodiment, a plurality of weight-reducing holes 7 are provided on the placement platform 6 to reduce the weight of the placement platform 6 .

[0022] In this embodiment, the upper end surface edge of the placement table 6 is evenly provided with limiting posts 8. The setting of limiting posts 8 prevents the radiation detection device from falling off the placement table 6. At the same time, in order to move the radiation detection device on the placement table 6, an anti-skid pad is embedded on the upper end surface of the placement table 6. The anti-skid pad improves friction.

[0023] Example 2

[0024] This embodiment provides a portable positioning tool for GIS ray detection, which has the same structure as the positioning tool in Example 1, except that the telescopic sleeve 4 is detachably connected to the mobile platform 1. The upper end surface of the mobile platform 1 is provided with a plurality of connecting studs, and the bottom of the sleeve 401 is provided with a mounting plate 2, and the mounting plate 2 is provided with perforations for the connecting studs to correspond one by one. After the column of the connecting stud passes through the corresponding perforations, it is screwed with the nut. The advantage of the detachable connection between the telescopic sleeve 4 and the mobile platform 1 is that when the device is not in use, the mobile platform 1 can be used to transport other items.

[0025] In this embodiment, a plurality of tilting rods 3 are provided on the peripheral side of the sleeve 401, and the lower ends of the tilting rods 3 are connected to the mounting plate 2. The tilting rods 3 are provided to provide connection stability of the sleeve 401.
