Embodiment Construction

[0024] figure 1 , figure 2 , image 3 , Figure 4 It is a structural schematic diagram of an embodiment of the prior art; wherein figure 1 main view, figure 2 for the left view, image 3 , Figure 4 is a local schematic. figure 1 , figure 2shows that in the prior art, the seat plate type single-person spreader mainly includes a working rope 1, a descender 2, a connector 3.1, and a loading device 4; when in use, the working rope 1 is fixed on the fixed end 1.2B. At a high place, the working rope 1 is tied with a special knot 1.1 on the descender 2, and then bypasses the first passing shaft 2.2A, and the human body 5 is fixed on the passing shaft 2.2 of the descending device 2 through the loading device 4 and the connector 3.1 on A. Because special knot 1.1 is arranged, human body 5 can not slide down, but can realize free descent by operating work rope 1. When it is necessary to descend, the operator only needs to lift up the free end rope 1.2A (the end of the rope...

Abstract

The invention relates to a suspension descending system. In order to overcome the problems that when existing seat board type single hanger is used, people need great effort to lift the rope during descending, even the rope cannot be lifted, and great trouble is brought to construction and operation. The invention provides the suspension descending system, wherein a deflection drawing piece is arranged to change the trend behind the special knot so as to change the frictional force of the special knot. When people is in high altitude, the gravity of the rope at the free end is large, and the human body operates the deflection drawing piece to deflect a descender, so that the rope after the special knot is in a free suspension state and the frictional force of the special knot is lessened. Therefore, the human body can descend automatically by own gravity or lifts the rope upward with little effort, and certain problems in construction and operation are solved.

Description

technical field [0001] The invention relates to a suspension lowering system, in particular to a suspension lowering system controlled manually by using the weight of the human body as gravity. Background technique [0002] In daily life, when cleaning the outer wall, a seat-type single-person spreader is usually used. When using it, first choose a fixed place on the roof to tie the rope, and use rubber pads for all the corners, edges and eaves of the rope. , to prevent friction and wear of the sling; and then tie a special knot in the descender on the seat suspension plate. Because of such a special knot, the hanging board will not slide down during work, and the person controls the rope and can operate freely. To put it simply, when the rope is lifted up, the hanging board will slide down a little bit, slide as much as you lift, and slide as fast as you lift, until the work is over. This tool can also be used in high-altitude exterior wall painting projects. Because whe...
