Compared with the prior art, the invention has the beneficial effects that:
1. when a constructor stands on the circular supporting plate for construction, sundries such as stones, bricks and the like can fall off from the upper side or the side face frequently to injure the constructor by smashing. And through set up metal protection network before constructor's body and make the debris that drop blockked by the protection network to avoid constructor injured, increase the security of construction.
2. Constructor during operation need rotate the health often and operate different positions, and circular layer board area is less, and frequent turning then probably can lead to constructor to drop from circular layer board to be injured. Therefore, the circular rotating block is arranged at the bottom of the circular supporting plate, the base of the circular rotating block is connected with the base through the balls, the mounting frame can rotate the circular rotating block when the structure of the mounting frame is sufficiently stable due to the cooperation of the rotating block and the through hole, the circular supporting plate fixedly connected to the circular rotating block rotates along with the circular rotating block, and accordingly construction personnel can change angles without rotating.
3. The foundation ditch bottom condition is most comparatively complicated, and the unable stable placing in the foundation ditch bottom of base, and make the unable work of constructor who stands on circular layer board. Therefore, fixing mechanisms are arranged on two sides of the base to solve the problem. The construction personnel rotate the hexagonal bolt head through using the electric spanner, and the hexagonal bolt head drives the connecting rod and rotates together, and the connecting rod drives the drill bit downstream in the sleeve, until the drill bit is squeezed into the ground below, fixes the base.
4. Through setting up horizontal damper and radial damper, can be so that when being located the staff construction on the circular layer board, most vibrations can be offset to the mounting bracket for the mounting bracket is more stable, and the staff is safer.
5. When not needing practical this installing frame, can make the installation piece of being connected with the lead screw meshing rise through the remote pole of rotating the lead screw top. The mounting block lifts with the stay bar. Because the metal protection net is rotatably connected with the stay bars and the rotating shaft, when the stay bars ascend, the metal protection net starts to be folded together and moves upwards. Therefore, the space can be saved when the device is not used.
