Abstract

A descender, being arranged with a rope pressing member (5) upwards or downwards sliding under the control of hands. The rope pressing member extrudes a wound rope (3.2) on a spindle (1) when upwards sliding, the friction force of the wound rope (3.2) is increased, and a human body (4) stops descending; whereas the wound rope is not pressed when downwards sliding, the friction force of the wound rope is reduced, and the human body descends. The descender has the beneficial effects that user only needs operating the rope pressing member on the descender during utilization process to move the rope pressing member downwards or upwards, and the human body can descend or stop descending. The problem of inconvenience of use in traditional eight-shaped ring-type, shackle type, or rod type descender, has been solved in present descender, which has the advantages of simple operation, safety and convenience.

Description

, ^ _ΑΗ+ , a descender

Technical field

The present invention relates to a descender, and more particularly to a descender that is manually controlled by gravity of the human body.

Background technique

In the "Technical Specifications for Safety of Seat Type Single Slings for Building Exterior Wall Cleaning", the types of descenders today include: rod type, multi-plate type, 8-word ring type and shackle type. When using the 8-word ring lowering device or the shackle type lowering device, the operator must lift the free end rope up when landing; when the rope length is long, the gravity is very large, and sometimes even the problem of lifting the rope is given. Construction and operation bring a lot of trouble. In addition, due to some safety issues, the shackle-type descender is currently not recommended for use.

Although the stick type is very safe, in actual use, the operator is also inconvenient to operate when descending; when using, the operator can wind the free end of the working rope around the sliding rope mouth to lock the lowering device, and slide the working rope from the lower book. The unwinding of the rope mouth can achieve a drop, but when unwinding, care should be taken to pull down the working rope to prevent sudden drop; such an operation causes great inconvenience to the user. Therefore, even if the 8-word loop downer is inconvenient in operation, people are still willing to choose it.

Summary of the invention

In order to solve the problem of inconvenient use of the bar type reducer, the present invention proposes a bar type descender, which is provided with a pressure rope member which is controlled by a human hand to slide up and down, and when the pressure rope member slides upward, the winding on the mandrel When the rope is squeezed, the friction of the rope is increased, and the human body stops falling; when the pressure rope member slides downward, the rope is no longer pressed, the friction of the rope is lowered, and the human body is lowered. The descending device proposed by the invention can be used not only as a hanging tool for building exterior wall cleaning, decoration, etc., but also as a building fire rescue, rescue or high-altitude life-saving, hanging tool during operation, and also as a personnel when airborne Special equipment.
