Problems solved by technology

The traditional fast escape method is to escape through facilities such as soft ladders and life-saving bags, but these facilities are expensive, take up a lot of space, and are inconvenient to use, especially for the elderly and weak
[0003] Most of the currently disclosed escape devices adopt the principle of double-rope intertwining, but the traditional double-rope intertwining escape device has low reliability and poor safety, and it has the following disadvantages when it is put into practical use: 1. 2. The falling speed is difficult to control; 3. The sliding friction of the rope generates a lot of heat, and the lifeline is easy to wear and tear, causing people to fall and become disabled.
Although some escape devices are equipped with additional rope clamping devices to improve reliability, such escape devices generally have the disadvantage of unnecessary waste of materials, which doubles the production cost of the product and is not conducive to popularization. use
Using the same set of life-saving devices back and forth at the same time not only wastes precious time in disasters, but also increases the risk factor of people in danger
In addition, quite a large part of the above two escape devices do not have the function of self-control speed, so the psychological burden of escapers is heavy, which is not conducive to the implementation of self-rescue.

Embodiment 1

[0027] An escape and rescue slow down device, including a housing 1, a clamping mechanism and a deceleration mechanism. The clamping mechanism and the deceleration mechanism are arranged in the housing 1; the clamping mechanism includes a pair of large gears 2 symmetrically arranged , 1 pair of small gears 22 and 1 pair of pulleys 3, wherein a large gear 2 and a small gear 22 are arranged on the same side, and the large gear 2 on the same side meshes with the small gear 22, and the large gear 2 is fixedly installed on the shaft 4 In the housing 1, the large gear shaft 4 and the pinion shaft 5 are connected by a connecting rod 6; the pinion 22 on the same side is installed coaxially with the pulley 3; a pair of symmetrically arranged pulleys 3 forms a through rope hole 7; The angle between the connecting rod 6 and the horizontal is an acute angle;

[0028] The reduction mechanism includes a pair of piston dampers 8, which are respectively installed under the two large gears 2. ...

Embodiment 2

[0030] As described in embodiment 1, the escape and rescue descending device differs in that:

[0031] The clamping mechanism also includes a pair of fixed rollers 12 and a pair of movable pulleys 13 symmetrically arranged, wherein one fixed roller 12 and one movable pulley 13 are arranged on the same side, and the fixed roller 12 on the same side is in phase with the movable pulley 13 Cut, the fixed roller 12 is fixedly installed in the housing 1 through the shaft 14, the fixed roller shaft 14 on the same side is connected with the movable pulley shaft 15 through the connecting rod 6, and a pair of symmetrically arranged movable pulleys 13 forms a through auxiliary rope The hole 16 is up and down opposite to the said rope hole 7, and the pinion shaft 5 on the same side is connected to the movable pulley shaft 15 through the connecting rod 6. The connecting rods 6 on the same side form three sides of a parallelogram, which can be deformed to reduce the distance between the opp...

Embodiment 3

[0033] As described in Embodiment 2, the escape and rescue descending device differs in that:

[0034] The escape rescue slow descender also includes an eccentric cam speed regulating device arranged below the rope hole, and the eccentric cam speed regulating device includes a fixed clamping block 17 and a movable clamping block 18, and the fixed clamping block 17 is fixed Set on the shell 1, the movable clamping block 18 is set on the shell 1 through the bolt 19, one end 24 of the movable clamping block is connected with the shell 1 through the spring 20, and the other end 23 of the movable clamping block is connected with the fixed The clamping blocks 17 are oppositely arranged. The fixed clamping block 17 and the movable clamping block 18 in the eccentric cam speed regulating device are normally closed and tightened, and are used to tighten the rescue rope. The rescue rope of the whole body can realize the purpose of self-controlling the descending speed: the spring deform...

Abstract

The invention relates to an escaping and rescuing descending lifeline and belongs to the technical field of life-saving equipment or device. The escaping and rescuing descending lifeline comprises a shell, a clamping mechanism, a speed reducing mechanism and an eccentric cam speed regulating device, wherein a piston damper is used for safe speed reduction and the clamping mechanism and the speed reducing mechanism are connected in a meshed manner, so the safety factor of a human body falling from a high place is increased; with the eccentric cam speed regulating device, the downward sliding speed of a rescued person can be controlled and can be kept in a safe speed range; and by adopting the speed regulating device, the rescued person can regulate descending speed by himself / herself. The escaping rescuing device provided by the invention is simple in structure, reliable in operation, convenient for operation, low in fault rate, quick in escaping and rescuing, easy to manufacture, low in cost and very favorable for promotion and implementation.

Description

technical field [0001] The invention relates to an escape and rescue descending device, which belongs to the technical field of lifesaving equipment or devices. Background technique [0002] In recent years, the city has developed rapidly, and there are many tall buildings, and fires also occur from time to time. How to escape from high places in a fire has become the focus of the public at present. The traditional fast escape method is to escape through facilities such as soft ladders and life-saving bags, but these facilities are expensive, take up a lot of space, and are inconvenient to use, especially for the elderly and weak. [0003] Most of the currently disclosed escape devices adopt the principle of double-rope intertwining, but the traditional double-rope intertwining escape device has low reliability and poor safety, and it has the following disadvantages when it is put into practical use: 1. 2, the falling speed is difficult to control; 3, the sliding friction o...
