Problems solved by technology

[0002] Existing escape descenders have a variety of structures, but they generally have defects such as poor safety, complex structure, and high manufacturing cost.
For example, the friction deceleration mechanism has poor safety, is afraid of oil and water
The structure of the chain reduction mechanism is complex, the manufacturing cost is high, and the noise is large and unstable
The structure of the single-rope hydraulic damping deceleration mechanism is complicated, and the manufacturing cost is high, so it must be equipped with a gearbox

Embodiment Construction

[0008] see figure 1 and figure 2 , the double-rope hydraulic damping slow-down device is mainly composed of a cylinder liner 1, an end cover 2, a left winding wheel 3, a left slow-down rope 4, a right rope-winding wheel 5, a right slow-down rope 6, a gasket 7, and a sealing ring 8. Left rotating shaft 9, left blade 10, right rotating shaft 11, right blade 12, damping liquid 13 and connecting bolt 14 constitute. The six left blades 10 are connected to the left rotating shaft 9, and the six right blades 12 are connected to the right rotating shaft 11 and installed in the container formed by the cylinder liner 1 and the end cover 2 respectively. The container is filled with a damping liquid 13, and the left The slow-down rope 4 is left-handedly wound on the left-handed rope wheel 3, and the left-handed rope wheel 3 is installed on the left rotation shaft 9, and one end of the left slow-down rope 4 is connected to people or objects to be slowly lowered, and the right slow-down r...

Abstract

A double-rope hydraulic damping descent control device is mainly composed of a cylinder sleeve, an end cover, a left descent control rope, a right descent control rope, a left rope winding wheel, a right rope winding wheel, a left rotating shaft, a right rotating shaft, a left blade, a right blade, damping liquid and the like. One end of the left descent control rope and one end of the right descent control rope are connected with a person or an object which needs to descend slowly. The left descent control rope and the right descent control rope are reversely wound on the left rope winding wheel and the right rope winding wheel respectively. The person or the object drives the left descent control rope and the right descent control rope when descending. The left descend control rope and the right descend control rope make the left blade and the right blade oppositely rotate in the space composed of the cylinder sleeve and the end cover through the left rope winding wheel, the right rope winding wheel, the left rotating shaft and the right rotating shaft respectively, wherein the space is filled with damping liquid. The momentum generated when the damping liquid moves impacts on the left blade and the right blade, the left blade and the right blade generate opposite torques, and therefore the aim of slowly descending the person or the object at a constant speed is achieved. The descent control device has the advantages of being simple in structure, safe, reliable, low in manufacturing cost, durable in use and the like.

Description

technical field [0001] The invention is a double-rope hydraulic damping descent device, which belongs to fire-fighting and life-saving equipment. Background technique [0002] Existing escape descending devices have various structures, but generally have defects such as poor safety, complex structure, and high manufacturing cost. For example, the friction deceleration mechanism has poor safety, is afraid of oil, and is afraid of water. The structure of the chain speed reduction mechanism is complicated, the manufacturing cost is high, and the noise is large and unstable. The single-rope hydraulic damping deceleration mechanism has a complex structure and high manufacturing cost and must be equipped with a gearbox. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a double-rope hydraulic damping descent device for the deficiencies of the prior art. [0004] The technical scheme adopted in the present invention is...
