Compared with the prior art, the invention has the beneficial effects that:
1. when a constructor stands on the circular rotating block for construction, sundries such as stones, bricks and the like can often fall from the upper part or the side surface 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. When the constructor works, the constructor often needs to rotate the body to operate different positions, the area of the circular rotating block is small, and frequent rotation can possibly cause the constructor to fall off from the circular rotating block, so that the constructor is injured. Therefore, the circular rotating block in the circle center is arranged at the bottom of the circular rotating block, the base of the circular rotating block in the circle center is connected with the base through the balls, the mounting frame can rotate the circular rotating block in the circle center when the structure of the mounting frame is sufficiently stable due to the cooperation of the rotating piece and the through hole, and the circular rotating block fixedly connected to the circular rotating block in the circle center rotates along with the mounting frame, so that a constructor can convert the angle 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 turning block. 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 axial damper and radial damper, can be so that when being located the staff construction on the circular turning block, 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 connecting shaft, when the stay bars ascend, the metal protection nets start to be folded together and move upwards. Therefore, the space can be saved when the device is not used.

When working, constructors often need to rotate bodies to operate different positions, the area of the circular rotating block 4 is small, and frequent rotation can cause the constructors to fall off the circular rotating block 4, so that the constructors are injured. Therefore, the circular rotating block 7 in the circle center is arranged at the bottom of the circular rotating block 4, the circular rotating block 7 in the circle center is connected with the base 6 through the balls, the mounting frame can rotate the circular rotating block 7 in the circle center when the structure of the mounting frame is stable enough due to the cooperation of the rotating piece 10 and the through hole 11, the circular rotating block 4 fixedly connected to the circular rotating block 7 in the circle center rotates along with the mounting frame, and accordingly construction personnel can convert angles under the condition that rotation is not needed.
Further, an axial damping mechanism 12 is further arranged between the circle center circular rotating block 7 and the base 6, and the axial damping mechanism 12 comprises a damping block 23 fixedly connected to the bottom of the circle center circular rotating block 7 and an axial damping spring 24, wherein two ends of the axial damping spring are fixedly connected to the damping block 23 and the base 6 respectively.

The bottom of the foundation pit is complex mostly, and the base 6 can not be stably placed at the bottom of the foundation pit, so that a constructor standing on the circular rotating block 4 can not work. Therefore, the fixing mechanism 5 is provided on both sides of the base 6 to solve this problem. The construction personnel rotate the hexagon bolt head 22 by using the electric wrench, the hexagon bolt head 22 drives the connecting rod 21 to rotate together, and the connecting rod 21 drives the drill bit 19 in the sleeve 20 to move downwards until the drill bit is driven into the ground, so that the base 6 is fixed.
Furthermore, the center of the circular rotating block 4 is rotatably connected with a screw rod 14, three mounting blocks 13 are arranged on the screw rod 14 at equal distances, the mounting block 13 at the uppermost end is rotatably connected with the screw rod 14, and the rest mounting blocks 13 are meshed with the screw rod 14.

Because the protective metal meshes 2 are rotatably connected with the stay bars 1 and the connecting shafts 3, when the stay bars 1 rise, the protective metal meshes 2 start to fold together and move upward. Therefore, the space can be saved when the device is not used.
Example 2
The embodiment is further improved on the basis of the embodiment 1, and the improvement content is as follows: the top end of the screw rod 14 is fixedly connected with a crank 18. The operator rotates the screw rod 14 by rotating the crank 18, which is more convenient and quicker.
In summary, the working principle of the invention is as follows: the constructor places the mounting frame at the bottom of the foundation pit and rotates the hexagonal bolt head 22 to drive the drill bit 19 into the ground to fix the base 6. Then the crank 18 is rotated to rotate the screw mandrel 14, the mounting block 13 engaged with the screw mandrel 14 descends on the screw mandrel 14, the stay bars 1 on the mounting block 13 descend together, and the metal protection net 2 is opened. After the metal protection net 2 is completely opened, a constructor stands on the circular rotating block 4, at the moment, the circular rotating block 7 with the circle center can be rotated by the help of other workers, and the circular rotating block 4 rotates along with the circular rotating block 7 with the circle center until the required angle is reached, and then the operation is started.
