Descending machine for absorbing energy through damping element

Abstract

The invention relates to a descending machine for absorbing energy through a damping element, and belongs to the technical field of firefighting and motion equipment. A lower rope wheel (3) and an upper rope wheel (5) butt against rubber springs (7) through grooves, so that the rubber springs (7) extend and absorb kinetic energy of personal descending. The rubber springs (7) butt against the lowerrope wheel (3) and the upper rope wheel (5) through rollers (71), and relatively roll to prevent the sliding friction with ropes (4), so that the service life of the ropes (4) is prolonged. The rubber springs (7) are wrapped by rubber layers, and are clamped with a secondary plate heat dissipating gap (61) and a main plate heat dissipating gap (12) through the rubber layers to prevent invasion and blockage of foreign matters, so that the safety and the reliability can be guaranteed; and the heat dissipating parts leave away from the lower ropes (4) for full heat dissipation. The damping energy absorption effect of the rubber springs (7) is adjusted through adjusting screws (66) and control ropes (9) to prevent acute fluctuation of the descending speed and to prevent the panic.

Description

technical field [0001] The invention relates to a descender, which belongs to the technical field of fire fighting and sports equipment. Background technique [0002] The descender strengthens the cushioning effect by increasing the friction force on the rope, so as to achieve the purpose of slow descent, and is used for expanding training, working at heights, outdoor sports and protecting rescuers and trapped persons in rescue. At present, people have proposed various descenders, and the known 8-character ring is a simple descender. The invention patent with the application number 201711285325.9 proposes a self-locking descender with a handle and a cam, which can be fastened to the rope and can be used for outdoor sports, rescue and high-altitude operations, which can prevent panic and avoid the risk of accidental descent . The invention patent with the application number 201280019576.1 also proposes a self-braking descender with anti-panic function, which is provided wit...

Problems solved by technology

[0004] Compared with the descending device, the descending device does not need to accommodate ropes, is light in weight, simple in structure, small in size, easy to manipulate, and good in heat dissipation, but it is easy to cause psychological panic

The descending device in the prior art is fixed on the rope, and the descending speed is controlled through the sliding friction between the descending device and the rope or between the rope and the rope. At the same time, the kinetic energy of the person descending is converted into heat energy, which will inevitably cause the local temperature of the friction part to rise. , it is easy to cause metal fatigue and deformation, and the rope is severely worn, which reduces the service life of the rope, and needs to be checked carefully in time

The current slow descent device winds the rope on the winding wheel, and through the friction or damping of the speed controller, the kinetic energy of the person's descent is converted into heat energy and kinetic energy of the rotating parts. failure risk
