Multiperson much-insurance reciprocating type lifesaving slow descending device

Abstract

The invention provides a medium-sized multiperson much-insurance reciprocating type lifesaving slow descending device. The slow descending equipment mainly comprises a rail folding and unfolding mechanism, a slow descending mechanism, a screw rod and nut drive mechanism, a bracket and a chain drive mechanism, wherein the movable slow descending mechanism is installed on the steel structure bracket and can shift a rail rope wheel; and a hand wheel rocks the chain drive mechanism so that the slow descending mechanism extends out, a rail folding and unfolding mechanism hand wheel is rocked to lay down a rail, and an escaping person descends along with a descending steel wire rope after hanging a safe hanging ring of a slow descending rope. The device enables a friction block to generate a centrifugal force by planet wheel acceleration to generate friction with a shell for carrying out slow descending; a rail sliding ring which is shown as the picture nine and has a brake function is also installed on the rail rope and prevents two manned steel wire ropes from winding together, and the sliding ring can be also held by a hand in emergency and stalling, and thereby the functions of deceleration and brake are realized; a ground buffer seat shown as the picture eleven is installed on the ground, has the effect of buffer and prevents damage to a human body due to overlarge impact; and the lifesaving slow descending device has the characteristics of simple operation, stable descending speed, much insurance, less land occupation, simple and practical structure, safety and reliability.

Description

technical field [0001] The present invention provides a medium-sized life-saving descending device that can be used by multiple people at the same time, is provided with multiple safety guarantees, is simple to operate, and can be used reciprocally, belonging to the technical field of high-rise life-saving devices. Background technique [0002] Most of the life-saving slow-descent devices that occur at present are small-sized slow-descent devices that can be used by individuals. This kind of slow-descent device has its flexibility, but it is not suitable for many people to use, and the efficiency is low; although some large-scale life-saving equipment can It is used by many people, but its operation is very complicated, requiring people on the ground and in the equipment at the same time, and the cost is high; in view of the shortcomings of various life-saving slow-down devices on it, the utility model specially designs a medium-sized one, which is simple in structure and e...

[0002]The life-saving descending devices that appear at present are mostly small descending devices that can be used by individuals. This kind of descending device has its flexibility, but it is not suitable for many It is used by one person, and the efficiency is low; although some large-scale life-saving equipment can be used by multiple people, its operation is very complicated, requiring people on the ground and equipment at the same time, and the cost is high; in view of the shortcomings of various life-saving slow-descent devices on it, this The utility model specially designs a medium-sized life-saving slow-down device with simple structure and convenient operation, which can be used by many people to escape at the same time.
