[0024] In this embodiment: the base assembly includes a fixed seat 301, the fixed seat 301 is made of 45 steel material, and four mounting holes 305 are evenly distributed at the four corners of the fixed seat 301. Two slide bars 302 are symmetrically mounted on the fixed seat 301. The slide bars 302 are cylindrical. The slide bars 302 and the fixed seat 301 are riveted together. A spring 303 is mounted on the slide bar 302. A baffle plate 304 is mounted on the top of the slide bar 302. The baffle plate 304 and the slide bar 302 are bolted. The fixed seat 301 is fixed to the ground through the mounting hole 305 and is connected to the fixed support frame 201. The slide bar 302 supports the limit spring 303. The spring 303 stores elastic force to push the lifting frame 101 to rise along the slide bar 302. The baffle plate 304 prevents the lifting frame 101 from separating from the slide bar 302.

[0025] In this embodiment: the frame assembly includes a support frame 201, the cross-section of the support frame 201 is a rectangular frame, the support frame 201 is bolted to the fixing seat 301, a sealing ring 202 is installed on the top of the support frame 201, a motor 203 is installed on the outer side of the bottom of the support frame 201, the motor 203 and the support frame 201 are bolted, a winding wheel 204 is installed on the output end of the motor 203, the winding wheel 204 is installed in the support frame 201, a steel cable 205 is wound on the winding wheel 204, the support frame 201 supports the motor 203 to drive the winding wheel 204 to rotate and wind or release the steel cable 205, and the sealing ring 202 ensures sealing to prevent dust from entering;

[0026] In this embodiment: the main component includes a lifting frame 101, which is a box-shaped structure and is made of 204 stainless steel. A detection host 102 is installed on the top of the lifting frame 101, and a fixing ring 103 is provided at the bottom of the lifting frame 101.
