Problems solved by technology

When the 8-shaped ring descender is used, the operator must lift 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, which brings great difficulties to the construction and operation. big trouble
In addition, due to some safety problems, the shackle-type descender is not recommended to be used at present.
Although the stick type is very safe, in actual use, it is very inconvenient for the operator to operate when descending; when in use, the operator can lock the descender by winding the free end of the working rope around the opening of the sliding rope, and untie the working rope from the opening of the sliding rope Then it will be able to descend, but when you untie it, you should pull down the working rope to prevent it from descending. Such an operation will bring great inconvenience to the user.

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with accompanying drawing

[0021] Such as figure 1 and figure 2 As shown, a rope descender has a rectangular frame shape and includes a body 1 and a rope adjustment structure. The rope adjustment structure is located inside the body 1 and includes a U-shaped lever adjustment mechanism 3, a speed adjustment button 2, a rope adjustment The moving block 4 and the rope stop shaft 5; the body 1 is made up of two hinges, and there is a U-shaped groove 1a1 in the hinge 1a, and a U-shaped lever adjustment mechanism 3 is installed through two supporting points on both sides in the groove; as image 3 A speed adjustment button 2 is arranged on the center position of the horizontal axis of the U-shaped lever adjustment mechanism 3 as shown; Figure 4 One end of the speed adjustment button 2 as shown is in contact with the rope brake block 4 and embedded in the adjustment groove 1b1 in the right hing...

Abstract

The invention relates to a rope descending device, in particular to a rock climbing and high building escape descending device. It includes the main body, U-shaped lever adjustment mechanism, speed adjustment button, rope brake block and rope stop shaft. The main use of the physical lever principle is to provide double stopping force for the rope through a speed adjustment button. The user can effectively control the speed of the body's descent with the minimum force during the descent. The design is simple in structure and easy in operation, can control the descending speed, is safe and reliable, and is an essential tool for rock climbing and escape from high buildings.

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 descender is used, the operator must lift 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, which brings great difficulties to the construction and operation. Big trouble. In addition, the use of the shackle-type descender is not recommended at present due to some safety problems. Although the stick type is very safe, in actual use, it is very inconvenient for the operator to operate when descending; when in use, the o...
