Compared with the prior art, the utility model has the following advantages:

The utility model is a hoisting and chiseling device for large-volume concrete blocks. A fixed pulley and a moving pulley are arranged on the steel pipe of the scaffold through the long cable and the short cable, and the electric hammer is hoisted. The purpose of carrying the chisel is to speed up the progress of the construction and improve the work efficiency. It solves the problem that the weight of the electric hammer in the prior art is too heavy, which slows down the construction progress.

Further, the lift of the electric hammer can be adjusted by the length of the long cable, and the relative position of the electric hammer in the horizontal direction can be adjusted by the length of the short cable, while the stiff spring can move flexibly within a small range.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Referring to Fig. 1, a hoisting chiseling device for large-volume concrete blocks includes a long cable 1, a short cable 2, a scaffold steel pipe 3, a fixed pulley 4, a moving pulley 5, a rigid spring 6, and an electric hammer 7 , large-volume concrete block 8, small spring 9, small pulley 10, bolt 11, large pulley 12, anchor frame 13. There are eight scaffolds 3, and there are two respectively in the front, back, left, and right sides of the large-volume concrete block, which play the role of supports.

Referring to Fig. 2, the mobile pulley 5 is in the shape of an oval pie. Pulley device is respectively arranged up and down, and a large pulley 12 is arranged on the top, and two small pulleys 10 are arranged on the bottom. Big pulley 12 bears on scaffold 3 steel pipes, and bottom small pulley 10 has long stay cable 1 and short stay cable 2 to pass through respectively. Mobile pulley 5 can slide freely on scaffold 3 steel pipes.

Referring to Fig. 3, the shape of the fixed pulley 4 is irregular, and the fixed pulley 4 includes an upper fixing device 41 and a lower pulley device 42; the fixing device 41 is axially provided with a through hole 43, and the fixed pulley 4 passes through The through hole 43 is provided on the scaffolding steel pipe 3 . The upper and lower parts are both pancake-shaped and at 90 degrees at the same time. There is a through hole 43 on the top, which is used to penetrate in the steel pipe of the scaffold, and the diameter is slightly larger than the steel pipe by 2mm.
