Abstract

FIELD: mechanical engineering; rescue appliances for humans and animals; self-rescuing of people at first, descending of construction workers. SUBSTANCE: device has housing with load suspending appliance in which flexible tape is laid passing in zigzag manner over brake rolls. Tape has friction surface and forms sections directed opposite to each other. Adhesion control acts in cross direction on these sections. EFFECT: provision of descending of people and any loads without assistance from any height at preset speed. 6 cl, 2 dwg

Description

 The proposed device relates to a means of moving goods from a height under the influence of gravity and can be used to evacuate people and other objects from the upper floors of buildings and structures during fires, lowering high-altitude workers, lowering cargo from a helicopter, lowering rescuers during mountain rescue operations and other emergency situations that require moving objects from a height.

 A device for a similar purpose is known (see German application N 2802832 from 07/28/79 IPC A 62 B 1/14).

 A device is known, described in German application N 3531391, published 12.03.87, IPC A 62 B 1/14, containing a housing through which a flexible rope and a brake element are passed, allowing to press the flexible rope to the wall of the housing.

 A disadvantage of the known device is that only a person can move with it, since the brake element is actuated by pressing the latter with the hand, and the speed of descent depends on the force of pressing the clamp adjuster lever.

 The closest analogue of the claimed invention is a device disclosed in the application of Great Britain N 2067725, cl. A 62 B 35/00, published. 07/30/81.

 The specified known device for transporting cargo under the action of gravity contains a housing in which rollers are installed in the upper and lower parts, a flexible load carrier made in the form of a tape with a friction surface that envelopes the rollers in a zigzag fashion with the formation of counter-moving moving sections of branches, and a belt clip adjuster.

 The claimed device is intended for the descent of people and for the descent of any cargo unaccompanied by a person from any height and at a predetermined speed.

 To this end, in a device for transporting cargo under the action of gravity, comprising a housing in which rollers are installed in the upper and lower parts, a flexible load carrier made in the form of a tape with a friction surface that envelopes the rollers in a zigzag fashion with the formation of counter-moving sections of branches, and a belt clip adjuster , counter-directionally moving sections of the tape branches are in contact with each other and with a clamp regulator installed between the rollers, mounted to move in the direction Perpendicular to the direction of movement of the tape to press the branches of the tape between each other and to the rollers.

 In this case, the working element of the pressure regulator is mounted on the housing with the possibility of movement in the transverse direction.

 In addition, the working element of the pressure controller has a streamlined surface.

 Moreover, the working element of the clamp controller is made in the form of a curved tape.

 And also the device for hanging the load is equipped with a special suspension.

 Along with this, the upper end of the tape is equipped with a device for engaging with a stationary object.

 A diagram of a device for transporting cargo under the action of gravity (hereinafter the device) and the principle of its operation is shown in FIG. 1 is a general view, and in FIG. 2 is a longitudinal section.

 The device comprises a box-shaped housing 1 in which there is an opening or other device 2 for hanging the load. Rollers 3 are installed in the upper and lower parts of the casing, between them with the possibility of moving in the direction perpendicular to the direction of movement of the tape 4, a pressure regulator 5 of the tape branches is installed together and pressing it to the rollers 3. A flexible tape with a friction surface passing inside the casing covers rollers in such a way that the zigzags of the branches of the tape in contact with each other and with the pressure regulator and when lowering the load moving in the opposite direction, one end of the tape is attached to a stationary object with a hook 6 or otherwise And the other, passing through the device in the manner described, single. The length of the tape is determined by the necessary height for lowering the load.

 The proposed device is applicable for lowering people and for lowering any cargo unaccompanied by a person from any height and at a predetermined speed.
