However, the conventional scaffolding set up on the facade of the side wall can only lay the asphalt waterproofing membrane on a part of the side wall. If the asphalt waterproofing membrane is to be laid on other parts of the side wall, the scaffolding must be hoisted and moved to the designated position as a whole, which is cumbersome and inconvenient. At the same time, it takes a lot of time to set up the conventional scaffolding, which affects the speed of the side wall construction, and it is not convenient for the workers to move up and down when laying the asphalt waterproofing membrane. The simple temporary bracket set up on the construction surface of the side wall needs to be repeatedly disassembled and assembled, which is not only time-consuming and laborious, but also the steel pipes and connecting fasteners used are prone to wear, resulting in reduced stability of the scaffolding, affecting the overall construction safety performance and the personal safety of the workers.

[0028] The utility model reels in the main steel cable 9 through the winch 7, and the splitter 3 moves downward under the pulling force of the main steel cable 9. The four steel cables 8 connected to the splitter 3 pass around the fixed pulley group to lift the operating platform 2 upward. The main steel cable 9 can be lengthened by reversing the winch 7 to lower the operating platform 2, thereby realizing up and down movement. The horizontal movement can be realized by the translation of the moving wheel group 5 at the bottom of the base 4, so that it is convenient for the operators to move up and down and horizontally when laying the asphalt waterproof membrane on the outer side of the side wall.

[0029] Furthermore, the fixed pulley block includes four side fixed pulleys 11 and four center fixed pulleys 12. The four side fixed pulleys 11 are respectively arranged directly above the four corners of the operating platform 2, and the four center fixed pulleys 12 are respectively arranged at the center of the top plate 1. The four steel cables 8 at the four corners of the operating platform 2 extend vertically upward and pass through the top of the side fixed pulleys 11 and one center fixed pulley 12 respectively, and then are connected to the splitter 3. The four steel cables 8 at the four corners of the operating platform 2 first extend vertically upward through the side fixed pulleys 11, and then extend horizontally from the bottom of the top plate 1 to the center of the top plate 1, bypass the center fixed pulley 12, and extend downward to the splitter 3, so as to avoid the space above the operating platform 2 being occupied by the inclined pull of the steel cables 8, and facilitate the standing of personnel.

A steering fixed pulley 13 is arranged between the central fixed pulley 12 and the side fixed pulley 11 of each fixed pulley group. The steering fixed pulley 13 is horizontally arranged at the bottom of the top plate 1. The two central fixed pulleys 12 and the upper movable pulley 32 connected to the same long steel cable are in the same spatial plane. The steel cable 8 bypasses the steering fixed pulley 13 so that its two ends are parallel to the central fixed pulley 12 and the side fixed pulley 11 respectively, so that the steel cable 8 can be accurately connected to the pulley grooves of the central fixed pulley 12 and the side fixed pulley 11, avoiding the situation where the steel cable 8 is obliquely connected and rubbed against the side wall of the pulley.

Both ends of the main steel cable 9 pass through the threading hole 21, so that the main steel cable 9 has no joint at the distributor 3 to avoid loosening. The end of the main steel cable 9 is fixed to the bottom of the winch 7 and crimped between the winch 7 and the base 4, which is more secure and not easy to fall off.

[0033] Furthermore, a slide groove 61 is provided on the vertical pole 6, and rollers 22 are respectively provided at the four corners of the operating platform 2. The four corners of the operating platform 2 are respectively abutted against the slide groove 61 through the rollers 22, which can ensure that the operating platform 2 always moves in the vertical direction, avoiding deviation due to external force during the up and down movement, and effectively providing safety protection for the operators.

[0034] Furthermore, a safety fence 23 is arranged around the operating platform 2. The safety fence 23 is provided with a gap for personnel to enter and exit. The gap is connected to a safety door 24 to further enhance safety protection.

[0035] Furthermore, in order to prevent the winch 7 from malfunctioning or the operating platform 2 from suddenly falling due to other reasons, a hydraulic buffer cylinder 41 is arranged above the base 4 to slow down the falling speed of the operating platform 2, prevent falling in all directions, and ensure safety. Specifically, the hydraulic buffer cylinder 41 can be arranged at the four corners of the base 4.

[0036] Furthermore, a ladder 25 is provided below the operating platform 2 at a position corresponding to the gap in the safety fence 23 , so as to facilitate personnel to go up and down the operating platform 2 .
