Problems solved by technology

[0004] In order to solve the disadvantages of complicated control structure and high manufacturing cost of the current cable-type (multi-plate) descenders, the present invention proposes a cable-type descender. By setting a soft control rope, when suspended, the working rope When the force is applied, the row rod is retracted upward, the friction force of the working rope increases, and the human body stops falling; when the soft control rope is pulled down by hand, the row rod is released downward, the friction force of the working rope decreases, and the human body falls

Embodiment Construction

[0033] figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 It is a structural schematic diagram of the first embodiment of the present invention, wherein figure 2 , image 3 , Figure 4 , Figure 5 It is a schematic diagram of the local structure. As shown in the figure, the descender is composed of a body 1 and several row rods 2.1. The body 1 has a left vertical rod 1.1 and a right vertical rod 1.2. One end of the row rod 2.1 is provided with a closed sliding hole 2.1.1A, and the row rod 2.1 passes through The closed sliding hole 2.1.1A is installed on the left vertical rod 1.1 of the body, the working rope 5 is fixed at a high place through the fixed end 5.1, and the working rope 5 passes through the opening sliding hole 2.1.1B of the row rod and is pressed on the row rod, and then the The free end 5.2 hangs freely to a lower place, and the human body 6 is connected and fixed with the body 1;

Abstract

A descender is provided with a soft control rope (4). During suspension, a working rope (5) is under stress, a drop-off rods (2.1) tuck upward, the friction of the working rope increases, and the human body ceases to descend; and when the soft control rope is pulled downward, the drop-off rods are released and unfolded downward, the friction of the work rope decreases, and the human body descends. The descender can be used as a suspension tool at the time of construction, such as cleaning and renovation of building external wall, but also can serve as a suspension tool at the time of building fire rescue, disaster relief, high-altitude lifesaving or personnel air dropping.

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 Plate Single-Person Spreader for Building Exterior Wall Cleaning", the types of descenders include: rod type, cable 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] The cable-type (multi-plate) descender is widely used, but it has many disadvantages such as complicated control s...
