Abstract

The invention discloses a descender aiming to solve the problem of inconvenience in use of existing descenders of 8-shaped annular type, shackle type or stick type. By the setup of a pressing-rope member which is manually controlled to slide up and down, when the pressing-rope member slides up, a rolling rope on a mandrel is squeezed, friction force of the rolling rope is increased, and a human body stops descending; and when the pressing-rope member slides down, the rolling rope is no longer squeezed, friction force of the rolling rope is decreased, and a human body descends. The descender has the advantages that the pressing-rope member on the descender is only needed to be operated manually to slide down or up in use, the human body can descend or stop descending, operation is simple, and the descender is safe and convenient.

Description

technical field [0001] The invention relates to a descender, in particular to a descender controlled manually by using the weight of the human body as gravity. Background technique [0002] In the "Safety Technical Specifications for Seat-type Single-person Spreader for Building Exterior Wall Cleaning Operation", the types of descenders include: rod type, multi-plate type, 8-shaped ring type and shackle type. When the 8-shaped ring type descender or the shackle type descender is used, the operator must lift up the rope at the free end when landing; when the length of the rope is very long, the gravity is very strong, and sometimes there is even a problem that the rope cannot be lifted, giving Construction and operation bring great trouble. In addition, the use of the shackle-type descender is not recommended at present due to some safety problems. [0003] Although the stick type is very safe, in actual use, it is also very inconvenient for the operator to operate when des...
