[0003] At present, the clamps are generally welded to small hanging baskets, upper and lower cages and aerial vehicles. The construction site is small, the clamps are not easy to tighten, and they slide down and shift during construction. It is inconvenient to go up and down, and it is inconvenient to disassemble. The clamps are easy to slip, which is a great safety hazard. In view of this, we propose a safe construction platform for the installation and disassembly of bridge clamps. Utility Model Content

In this way, the hanging rings are dispersedly fixed on one side of the concave load-bearing plate, which can optimize the gravity distribution and reasonably avoid the overall center of the platform. This can improve the stability of high-altitude operations, expand the space for construction and extension, and also increase the number of construction workers. The overall structure can be used by only cooperating with a crane and a lifting rope, is not restricted by the site, and reduces the safety hazards of high-altitude operations.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model arranges an open-and-close hollow plate structure in the concave load-bearing plate so that the weight of the overall structure is heavier on the right and lighter on the left, so that the center of gravity is biased toward one side of the concave load-bearing plate. In this way, the hanging rings are dispersedly fixed on one side of the concave load-bearing plate to optimize the gravity distribution and reasonably avoid the overall center of the platform, so as to improve the stability of high-altitude operations, expand the space for construction extension, and also increase the number of construction workers. The overall structure can be used only through the cooperation of a crane and a hanging rope. The open-and-close hollow plate can be directly inserted into the outside of the column when in use, so that the column can enter the through-slot, and then the opening of the hollow plate can be closed to form a surrounding effect, which is convenient for high-altitude operations, is not restricted by the site, and reduces the safety hazards of high-altitude operations.

Two corresponding support plates 5 are fixedly arranged on the top of the concave load-bearing plate 101 and the hollow plate 102. A guide rod 6 interlaced with the clamp 3 is installed between the two support plates 5 on one side, and a limiting piece 7 combined with the support plate 5 is installed on the side end of the guide rod 6; the position of the clamp 3 can be limited by the cooperation of the support plate 5, so that it is not easy to deviate during the high-altitude disassembly and assembly operation, thereby improving the safety of the operation.

[0027] In an embodiment of the utility model, a slot 501 is formed on the side wall of the support plate 5, and two arc-shaped limit plates 502 are fixedly provided on the opposite sides of two support plates 5 on one side, and the arc surfaces of the two arc-shaped limit plates 502 face oppositely. The two arc-shaped limit plates 502 are designed with the center of the circle facing oppositely to achieve an arc-shaped clamping effect.

[0028] In the embodiment of the utility model, the hollow plate 102 includes two first hollow plates with movable grooves, and the second hollow plates are movably installed in the movable grooves of the two first hollow plates, and the tops of the side ends of the second hollow plates on both sides are fixed with corresponding connection blocks.

During use, it can be sleeved on the outside of the support column through the through-slot 103 on the support base plate 1, so that it can move up and down around the support column. The design that the gravity of the concave load-bearing plate 101 is greater than that of the hollow plate 102 can improve the stability of the support base plate 1 during movement, and it is not easy to offset and tilt. In this way, stability can be maintained when construction personnel work at high altitudes.
