Abstract

The utility model provides a life saving device at high altitute which can descend or ascend with people. One end of the wire cable is fixed at the high place of the building and then drops downwards. A lifting machine with a safety belt can be locked on the wire cable with people and is internally provided with a fixed friction component and a movable friction component; wherein, the movable friction component is against a spring which is against the screw sleeve through a top rod; and then the top rod passes the screw sleeve and is connected with a handle; the screw sleeve can be adjusted to determine the descending speed, and the lifting machine can be deadly clamped on the wire cable by tightly holding the handle. In case the device is for permanently attaching to the high building, positioning forks are arranged along the wall where the wire cable drops, and a foldable door-shaped bracket is arranged on the ground and is provided with a pulley group at the upper part and an electric roller at the lower part which can drive the wire cable to move up and down. When being static, the wire cable can lift people; once the wire cable moves upwards, the lifting machine is deadly clamped and can ascend people. The wire cable can be arranged in a wheel sleeve and hanged at the lower end of the lifting machine for carrying along by people. Also, the device is applicable to the recreation measures descending or ascending.

Description

The high altitude escape lifesaving appliance

The utility model is escape and the lifesaving appliance that descends or rise about a kind of people of making who is attached on the skyscraper, and also is suitable for from the recreation facility of high-altitude decline or rising.

When the numerous skyscraper in city ran into accident such as fire, blast, people wished to arrive safely and fast the outer safe ground of this building, and some handicapped people is badly in need of succouring on the people of outside.Technique known is when the residing position of people that needs escape is not too high at present, rescues the people with aerial ladder, but untimely, especially waits to rescue personnel more for a long time, more needs repeatedly lifting aerial ladder; Moreover be at ground venting pad, allow the survivor jump off from eminence, greatly dangerous.When the residing position of survivor is very high, need and please succour by helicopter, this is impossible under many circumstances.In addition, people also wish to have a kind of recreation facility that descends or rise from the high-altitude with simple apparatus, by this amusement on ordinary days, temper the technical ability from high altitude escape.

The purpose of this utility model provides a kind of being attached on the high constructure need not train the device that can reduce to ground safely and fast for the survivor, and this device still can rise to required eminence fast with the salvor.

Another purpose of the present utility model provides the recreation facility that a kind of high-altitude descends or rises, and makes people temper technical ability from high altitude escape in amusement on ordinary days.

The purpose of this utility model is to realize like this, the upper end of one sagging wirerope is fixed on the top in required place, again a tubular lifter is locked on this wirerope, its lower end is connecting safety belt, this elevation mechanism outer covering is by hinged, and form by two housings of retaining mechanism, in a housing, fixing and deciding friction member, in another housing dynamic friction piece is installed, it is propped up by spring behind, swivel nut outside housing offsets this spring through a push rod and a knob again, handle on push rod runs through swivel nut and is hinged on housing links to each other, at the scale that its position of indication is arranged near the knob place.In use that lifter and wirerope locking is good, as to press end user's body weight adjusting knob position, making has rational frictional force between guiding principle cable and the friction member, to obtain desirable decrease speed, then safety belt is linked to each other with the people and can descend along wirerope.If firmly handle can increase the frictional force of friction member to wirerope, make reduction of speed slack-off, can not slide on wirerope until being stuck.If lifter is stuck on wirerope, and wirerope is upwards spurred, then can be with the people to rise.

Again according to different use occasions, specify the method that realizes this purpose below:

1, being used for doing the escape that descends from high-rise reaches from ground liter relief:

With a wirerope doubling and make the beginning sagging, with pulley it is hung over roof and along wall the location fork is installed through pedestal through the place at it, its prong one side is installed with hush panel, the side's of having platform and retainer spring match on its pedestal axle, and articulated portal trestle is located on ground, and assembly pulley is arranged at its top, electric reel is arranged at the bottom, ring-type is walked around and connected into to wirerope in proper order, the articulated checkered plates in the portal trestle outside, and elastic belt is being adorned in the inboard.Portal trestle crouches in ground at ordinary times, and its checkered plates flushes with ground, during use it is upwards turned up, and fixes with the downward folding of checkered plates and with ground simultaneously, portal trestle can be located generation impact that the elastic belt on it can prevent the user just in case decrease speed is too fast.When the somewhere needs with this device decline, to locate the active pin shaft of location fork one side earlier extracts, the rotation hush panel is sealed wirerope and is with active pin that it is locked with the location fork, to keep the stable of wirerope, the upright good portal trestle of ground people simultaneously, but do not start electric reel can descend as enforcement as described in preceding, when running into following location fork, its can be automatically downwards folding fall and do not hurt sb.'s feelings.The people such as the need on ground rise, and can start electric reel and can be with the people to rise as stuck with wirerope as described in preceding.The invar cable has joint, so only should make wirerope lifting repeatedly according to forward and reverse rotation of electric reel.

2, be used for the escape that from high-rise, descends merely:

This kind form is often more in reality, at this moment, the upper end of single sagging wirerope is fixed on the top in required place, other installation is same as previously mentioned, but the portal trestle top need not assembly pulley, its bottom does not have electric reel yet, and this wirerope only need be fixed on the crossbeam of portal trestle, can implement the escape that descends as previously mentioned.

3, the recreation facility that is used for the high-altitude landing or rises: build a high tower and portal trestle earlier, just portal trestle herein need not fold and get final product, and need not to set the position fork on the body of the tower yet, realize descending and rising as need, can descend merely as need by as enforcement as described in 1, by getting final product as enforcement as described in 2.

4, be used to carry use:

Wirerope is around on the wheel shaft, places a housing to become the wheel cover, and connect from locking and hanging hook in the exposed section, this is taken turns to put and is also adorning from locking and hanging hook, can hang over the lower end of lifter.Be pulled outwardly out earlier wirerope during use, again with lifter with its locking, and will take turns cover and safety belt and lifter lower end and hang up properly, wirerope is hung on any firm place, can descend as enforcement as described in preceding, wheel shaft can discharge wirerope thereupon rotating.This should not be used to be with the people to rise.

The beneficial effects of the utility model are simple in structure, dependable performance, and the low easily enforcement of cost.

Following adjoint and embodiment specify the utility model
