Abstract

The invention discloses an adjustable slow descending device for escaping from a tall building. The device comprises members such as a main plate (1), a fixed pulley (4), a control handle (5), a rope (8) and the like, wherein the main plate (1) is provided with a group of damping through holes (3) and one to two damping adjusting teeth (2); damping force produced by the rope (8) which passes through the through holes (3) in a reciprocating way prevents people or heavy objects from sliding downwards in an accelerating way; when the device is used, the rope (8) can be conveniently embedded into or pulled out of the damping adjusting teeth (2) according to the weight of a descending object, so that damping force is adjusted; and in a descending process, descending speed can be controlled by operating the control handle (5), so that safe and slow descending of people or heavy weights are further ensured. The device has a simple structure, is convenient to adjust, is controlled reliably and can be used repeatedly.

Description

High-rise life saving controllable type slow descending device

The present invention relates to a kind of controllable type slow descending device that is used for the fire of high-rise building life-saving.

In the prior art, being used for the slow descending device that high-rise life saving uses has rope to add versions such as gear, pulley, hydraulic pressure, has the problem of certain aspect such as complex structure, troublesome maintenance, use inconvenience to some extent.Patent of invention (application number 85103639 as the Chinese patent bulletin, day for announcing 1986-11-26, inventor Korea Spro Yushan) " safety controllable slow landing apparatus ", then structure is very simple, mainly form by a rope band and a porous plate, but following deficiency is arranged: the one, because often there are clasp or hook in the rope band two ends, under emergency situation, if cumbersome according to descender weight adjusting damping force; The 2nd, the dynamics size control weight decrease speed that armrest is directly held rope band and porous plate with a firm grip, the reliability deficiency, and also used rope band can only be enough thick, soft yarn fabric, otherwise be difficult to control; The 3rd, do not put stuck pulley, may cause people or weight not to descend smoothly because of stiction reason rope band is stuck.

In order to overcome the weak point of said apparatus, the invention provides a kind of simple in structure, easy to adjust, reliable high-rise life saving slow descending device of control.

The technical solution adopted for the present invention to solve the technical problems is: device is made up of mainboard (1), fixed pulley (4), joystick (5) and the rope members such as (8) with sufficient intensity and length.Mainboard (1) has one group of damping through hole (3) of arranging according to certain rules, and rope (8) must overcome damping forces such as distortion elastic force and frictional force when coming and going by damping through hole (3), makes the weight decrease speed slow down; This damping force comes and goes the number of times that passes mainboard (1) with rope (8) and increases and decreases.There is one or two can conveniently embed or deviate from the damping regulating tooth (2) of rope (8) on the mainboard (1), can rope (8) be embedded or deviate from damping regulating tooth (2) according to descender weight situation during use, come and go the number of times that passes mainboard (1), the damping force of adjusting device to change rope (8).Damping through hole (3) the whole story two ends or necessary place fixed pulley (4) is arranged, can prevent that rope (8) is stuck and causes people or weight not to descend smoothly.Simultaneously, have on the mainboard (1) around the joystick (5) of bearing pin (7) swing, joystick (5) has a control convex surface (6); Control convex surface (6) changes with joystick (5) swing with the gap of mainboard (1); Manipulation joystick (5) can will roll tight by rope (8) herein or loosen, and effectively control decrease speed, and guarantor or weight safety are slow falls.There is hanging hole (9) at mainboard (1) two ends, are used to the usefulness that connects safety belt or hang on fixed support.

Slow descending device provided by the invention can back and forth use for many people, and can implement automatic control or his control.When many people use, utilize hanging hole (9) that this device is hung on the fixed support of presetting windowsill, rope (8) is connected with survivor's safety belt on one's body from the near end of slow descending device main body, and the other end is thrown to downstairs, and joystick (5) is by treating that upstairs the survivor handles; After the survivor of elder generation steadily landed, the other end of rope (8) had risen and has put in place, back and forth uses for the latter.Also rope (8) can be fixed in the windowsill support from the near end of slow descending device main body, the other end is thrown to downstairs, survivor's safety belt on one's body is connected with hanging hole (9) on the mainboard (1), and the people together descends with slow descending device, and joystick (5) is handled by survivor oneself.

Slow descending device provided by the invention use simple in structure, reciprocal, adjustable controlled, be easy to safeguard that the person that can make the high-rise life saving more steadily, safety is slow falls.

Accompanying drawing 1 is the example structure schematic diagram of controlling type safety slow descending device of the present invention.

Be described further below in conjunction with drawings and Examples.

Shown in the accompanying drawing 1, the mainboard of embodiment (1) stripe design, two ends respectively have one to be used to connect safety belt or to hang support bracket fastened hanging hole (9), the single-row arrangement of damping through hole (3), three fixed pulleys (4) are respectively in the position, upper, middle and lower of mainboard (1); Respectively there is a damping regulating tooth (2) the middle upper and lower both sides of fixed pulley.Accompanying drawing 1 is depicted as damping regulating tooth in rope (steel wire rope) (8) embedding, deviates from damping regulating tooth down.Joystick (5) has wedge shape control convex surface (6), constitutes " cutting " shape with mainboard (1), around bearing pin (7) swing.Mainboard (1) has and the corresponding hole slot of control convex surface (6).If rope (8) is fixed in the windowsill support from the near end of slow descending device main body, then can throw to the other end downstairs, as long as survivor's safety belt on one's body is connected with hanging hole (9) on the mainboard (1), can steadily descend.The decline process is if speed is too fast, as long as mainboard of holding with a firm grip (1) and joystick (5), rope (8) is promptly headed into the corresponding hole slot of mainboard (1) and is rolled tight by wedge shape control convex surface (6), just as " brake ", just can effectively control decrease speed, guarantee that safety lands.

Claims

1. high-rise life saving controllable type safety slow descending device, this device has rope (8) and mainboard members such as (1), mainboard (1) has one group of damping through hole (3) that distributes according to certain rules, and it is characterized in that has damping regulating tooth (2), fixed pulley (4), joystick (5) and hanging hole (9) on the mainboard (1).
