The entire clamping mechanism 6 does not need to clamp the bracket in steps, and can clamp brackets of various specifications at the same time.

[0082] Specifically, the lifting assembly includes a group of multi-section electric telescopic rods 5 , one end of the multi-section electric telescopic rods 5 is fixed to the top of the support platform 4 , and the other end of the multi-section electric telescopic rods 5 is fixed to the bottom of the rectangular frame 601 .

[0083] Working principle: The whole device is installed on the guardrail of the lifting platform through the support mechanism 1 ( Figure 8 As shown), the bottom of the bracket is then placed on the clamping mechanism 6, that is, the two clamping plates 110 in the clamping structure are placed on the lifting platform on both sides of the guardrail, and the double-threaded rod 109 is manually rotated, and the double-threaded rod 109 brings the two clamping plates closer to each other until the clamping plates clamp the guardrail; the clamping mechanism 6 clamps the bracket (as shown Figure 8 As shown); the failure mechanism first makes the locking mechanism 7 fail, that is, the second rotating column 13 is manually rotated, and the second rotating column 13 pushes out the two slides 16 through the two third connecting rods 15, and the sliding plate 16 pushes the movable plate 701 to the outside through the connecting rod 17, and the positioning pin 702 on the movable plate 701 is pulled out of the positioning hole, and the second spring 704 is compressed. If the positioning holes on the two square rods 10 are not aligned with the positioning pin 702, the movable plate 701 cannot use the force of the second spring 704 to insert the positioning pin 702 into the positioning hole; the lifting platform rises, if the entire device is not located in the middle area of ​​the tunnel, the column 8 on one side of the support platform 4 first contacts the top of the tunnel, the lifting platform continues to rise, and the column 8 slides with the tunnel. At this time, the support platform 4 slides on the guide rail 2 through the slide 3 until the two columns 8 on the support platform 4 contact the top a of the tunnel, and the support platform 4 is located in the middle of the tunnel (as shown Fig. 9 As shown), but the support platform 4 is not necessarily perpendicular to the generatrix of the tunnel (as shown Fig.10 As shown, the tops of the two square rods 10 are respectively located on the second busbar c and the third busbar e, the top of the tunnel is arched, the square rods 10 on the third busbar e are lower than the columns 8, and the tops of the columns 8 are located on the first busbar b), so that the locking mechanism 7 works, and then the support platform 4 is swung, until the tops of the columns 8 and the tops of the square rods 10 are located on the same busbar (horizontal plane), the locking mechanism 7 locks the two square rods 10 (when the tops of the columns 8 and the tops of the square rods 10 are located on the same busbar (horizontal plane) , The positioning pin 702 is inserted into the positioning hole to complete the locking), thereby achieving positioning, and the lifting assembly raises the clamping mechanism 6 until the bracket contacts the top of the tunnel, and the worker uses tools to fix it, and then installs the camera.
