Abstract

The utility model discloses a manpower lifting escaping device, comprising a plate shaped frame and a chassis, a reverse self-locking gear worm, a clutch, a roller with an escape rope and a braking device which are fixed and mounted on the frame in turn, wherein a worm gear axle is connected with a roller axle by the clutch and a handle of the worm exposes at one side of the chassis and the clutch and the braking device are controlled by a clutching/braking coupling device on the frame, an operation rod handle of the coupling device is arranged at another side outside the chassis. The clutch is at the separation state by the operation rod and the human may descend; if the operation rod is triggered along the reverse direction, the clutch is changed into the combined state and the worm crank is rotated along the forward direction, the worm gear drives the roller axle to tighten the rope, so as to make the human rise. The manpower lifting escaping device may rise or descend by self-control and the descending speed can be adjusted and the structure is simple, the control is flexible and the person can quickly escape from the high building.

Description

Manpower lifting escape device

Technical field

The utility model relates to a kind of escape device for high-rise buildings that uses rope to descend, the particularly a kind of escape device for high-rise buildings that can realize the lifting conversion.

Background technology

The existing escape device for high-rise buildings that uses rope to descend only has the decline function, and the people is dangerous as if meeting in the way that descends, or must take a risk to pass through, or just stops to descend.Risk brings injury by meeting, and stopping to descend can not overlong time, otherwise danger is bigger.

Summary of the invention

The purpose of this utility model is to overcome the defective that existing escape device for high-rise buildings only can descend, provide a kind of people of escape can control the device of its rising or decline, not only in the decline process, can control the speed that descends, and when running into the below when dangerous, timely conversion direction, upwards rise, the approach that averts danger, other selects best-effort path.

The technical scheme that realizes above-mentioned purpose is: a kind of manpower lifting escape device, comprise a tabular support and casing, be installed with the turbine and worm of one group of reverse self-locking on the described support from bottom to top successively, one cover clutch, a cylinder and a brake gear that is wound with escaping rope, be connected by clutch between turbine wheel shaft and the drum shaft, the crank of worm screw is positioned at the outer side of casing, brake ribbon on the brake gear cooperates with drum shaft, on the support between clutch and the brake gear, be installed with a clutch/brake linkage, the joystick lever of linkage is positioned at the outer opposite side of casing, the through hole that one end of escaping rope passes upper part of the frame is exposed at the outside of casing, and respectively there is a hole that connects braces at four angles of support.

Above-mentioned linkage is made up of an axostylus axostyle and capstan winch and two connecting rods that are fixed on the axostylus axostyle inner termination, the shift fork of clutch is hinged by one side of a connecting rod and capstan winch, and the movable end of brake ribbon is by hinged by the another side of another root connecting rod and capstan winch.

When the people need escape, at first braces is enclosed within on the health, latch closure on the braces is socketed in the hole at each angle of support, again the escaping rope termination is fixed on a certain high point, then health is placed outside window or some escaping exits outside, rotate the control stick of linkage, make clutch be in released state, this moment, human body began to descend, and in the decline process, can control the speed of decrease speed by the angle of pulling control stick.If when in the way that descends, facing a danger, firmly pull control stick, this device is braked fully, oppositely pull control stick then rapidly, at this moment, linkage will make clutch be in bonding state, forward rotation worm screw crank then, turbine will drive the drum shaft backward rotation, haul, and the people is risen.

The utility model can rise and can fall, and lifting is from main control, and decrease speed can be regulated, and it is simple in structure, and control can make the people fast from high-rise life saving flexibly.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 and Fig. 2 are the schematic diagram of the utility model flat condition.

As depicted in figs. 1 and 2, the utility model manpower lifting escape device comprises a tabular support 1 and casing 2, be installed with turbine and worm, a cover clutch 5, a cylinder 6 and a brake gear that is wound with escaping rope 15 of one group of reverse self-locking on the support 1 successively, turbine wheel shaft, clutch core axis, drum shaft are in together on the same axis.Be connected by clutch 5 between the axle of turbine 3 and the axle of cylinder 6, the crank of worm screw 4 is positioned at a casing side of 2 outward, and the brake ribbon 8 on the brake gear cooperates with drum shaft.On the support 1 between clutch 5 and the brake ribbon 8, be installed with a clutch/brake linkage, this linkage is by an axostylus axostyle 7 and a capstan winch 12 and a connecting rod 10 that is fixed on axostylus axostyle 7 inner termination, 11 form, the shift fork 9 of clutch is hinged with one side of capstan winch 12 by connecting rod 10, the movable end of brake ribbon 8 is by the another side hinged (as shown in Figure 1) by connecting rod 11 and capstan winch 12, handle 14 is installed on the external end head of linkage axostylus axostyle 7, this handle 14 is positioned at the opposite side of casing outer 2, the upper position of frame 1 is equipped with a through hole, the correspondence position of this through hole is equipped with a fixed pulley 17, one end of escaping rope 15 is walked around fixed pulley 17 and is passed the outside that through hole is exposed at casing, and respectively there is a braces connecting hole 16 at four angles of support.
