Hand-operated high-altitude operation lifter

Abstract

The invention discloses a hand-operated high-altitude operation lifter. The hand-operated high-altitude operation lifter structurally comprises a movable hook, a connecting hanging ring, a steel wirepulling rope, a hand-cranking rod, a rope outlet clamping seat, a wire winding device, a stretching distance displayer and a fixing clamping block, wherein the fixing clamping block is welded on the surface of the lower end of the wire winding device, the surface of the front end of the wire winding device is embedded with a stretching distance display, the hand-cranking rod is nested and connected to the other end of the wire winding device, the rope outlet clamping seat is arranged on the upper end surface of the wire winding device, the other end of the steel wire pulling rope is connectedto the inner surface of the wire winding device through the rope outlet clamping seat, one end of the steel wire pulling rope is connected with the connecting hanging ring, the connecting hanging ringis connected with the movable hook in a buckling mode through the mutual combination of components, and the steel wire pulling rope can be emergently braked when the steel wire pulling rope is seriously broken caused by abrasion in the using process of the steel wire pulling rope, so that the occurrence of potential safety hazards is effectively avoided, the drawing distance indicator of a current pulling rope can be intuitively seen by a user, the operation is convenient, and the practicability is high.

Description

technical field [0001] The invention is a hand-operated lifter for high-altitude operation, which belongs to the field of high-altitude operation equipment. Background technique [0002] The so-called high-altitude operation refers to the operation carried out by a person at a high place based on a certain position. Any operation at a high place where the fall height reference plane is 2 meters or more may fall is called high-altitude operation. [0003] The prior art is easy to cause potential safety hazards to construction personnel due to serious wear and tear after the steel wire stay rope has been used for a long time in the working process, and has poor practicability. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hand-operated lift for high-altitude operations, so as to solve the potential safety hazards caused by the severe wear and tear of the construction personnel in the prior...
