The base is provided with a lever arm angle adjustment mechanism.

The lever arm angle adjustment mechanism includes a hydraulic cylinder and a piston rod arranged in the hydraulic cylinder, the lower end of the hydraulic cylinder is pivotally connected to the base, and the upper end of the piston rod is connected to the The lever arm is axially connected.

A pulley is axially connected to the free end of the lever arm, and the steel wire rope goes around the pulley.

The reel assembly includes a reel and flanges fixedly connected to both ends of the reel, the steel wire rope is wound on the reel, and the output shaft of the reducer is connected to the flange at one end. The flange plate is fixedly connected, and the flange plate at the other end is axially connected with the reel support.

There are two groups of the steel wire rope retractable components.

The positioning mechanism includes a support rod and an anti-slip sleeve, the support rod passes downward through the base and is screwed with the base, and the anti-slip sleeve is sleeved on the support rod.

The manned equipment is a hanging basket or a hanging box.

The motor is a two-speed motor, and the reducer is a worm gear reducer; since the motor adopts a two-speed motor, when lifting upwards, it can rise quickly first, and when it is close to the required height, change the speed and slowly rise to reach the designated position Brake when necessary to ensure the safety of workers.

Compared with the prior art, the utility model has the advantage that the lifting device is placed on the roof of the building, the steel wire rope is lowered, and then the manned equipment is hoisted from the ground, and braked after rising to the required height, the operator can then The repair, maintenance, and cleaning of the outer wall of the building are safe, reliable, and work efficient; and because the wire rope retractable assembly is equipped with a lever arm angle adjustment mechanism, the angle of the lever arm can be adjusted to control the operator and the wall. distance between faces.
