Abstract
The utility model discloses a high-altitude escape sling, which comprises an engine base, a rotating reel arranged on the engine base, and a steel wire rope wound on the reel, and the end of the steel wire rope is used for being fixedly connected with the body of an escaper. The high-altitude escape sling is characterized in that a hydraulic pump is also arranged on the engine base, and the rotating shaft of the reel is in transmission connection with the input end of the hydraulic pump through a gear set. With such a design, the static energy generated during the falling of the escaper is consumed by the hydraulic pump or an air pump, and dynamic balance is achieved, so that the escaper can smoothly fall to the ground from a high place. The high-altitude escape sling has the advantages of simpleness and easiness in use, stability in falling, safety and reliability.
Description
Technical field
The utility model relates to the emergency escape apparatus technology, is used in particular for the equipment that personnel descend from the high-rise building high-altitude safe.
Background technology
Along with the fast development of urban construction, high-rise, high-rise building is increasing, in case disaster or accident occur in these high levels, high-rise building, it is very crucial how withdrawing escape rapidly in the building.And directly down descend from exterior wall high-rise, high-rise building is a kind of fast mode, for this reason, many pulley mechanism formula decline escape devices have appearred, but these devices adopt pulley or assembly pulley, in use all need the escape personnel to use the hand control rope, to control the decrease speed of self, operation easier is big, and need certain skill, under tired, the terrified state of clutch ordinary person body and mind, be difficult to effective control; In addition, this class device is to apply pressure to the frictional force that produces between the rope by staff to overcome gravity, in the decline process, can produce high temperature with the violent friction of rope, protects the safety that improper meeting directly influences the escape personnel; On the other hand, the rope that cooperates with pulley or assembly pulley is divided into two groups up and down at least, hangs down outside high-rise, high-rise building, is subjected to high-altitude wink wind or the influence of misoperation, as easy as rolling off a logly the disorder cable phenomenon that rope twines mutually occurs, even can cause tangling and the danger that can't descend.
The utility model content
The purpose of this utility model is the weak point that overcomes above-mentioned prior art, proposes a kind of usefulness, smooth decreasing, safe and reliable slow machine that falls of high altitude escape of being simple and easy to.
The purpose of this utility model is achieved by the following technical solution: the slow machine that falls of high altitude escape, include support, be loaded on the rotating drum on the support, be wound in the steel wire rope on the reel, the termination of steel wire rope is in order to be connected with escape personnel's health, it is characterized in that: also be provided with hydraulic pump on the support, the rotating shaft of reel is in transmission connection by the input of gear train and hydraulic pump.Further, what install in the rotating shaft of reel is toothed disc, and toothed disc is connected with hydraulic pump by pinion.Also be provided with caliper on the support, caliper is held in the mouth slim toothed disc and is formed hydraulic braking with it and connects.Hydraulic pump can be substituted by air pump.Between the rotating shaft of slim toothed disc and reel single direction ratchet is housed.Hydraulic pump is furnished with the oil storage kettle, on the hydraulic circuit of hydraulic pump flow control valve is housed.Also be provided with the steel wire rope hold down gag that prevents that steel wire rope is loose on the reel.Also be provided with steel wire rope backrush device in the rotating shaft of reel.Described hydraulic pump is gear pump, vane pump.
Such design, the potential energy when utilizing hydraulic pump or air pump consumption escape personnel to descend, and produce dynamic balancing, make the escape personnel drop to ground by eminence reposefully.Its advantage is: 1, simple in structure, use simple and convenient; 2, need not people's hand control decrease speed, but automatic steady descends; 3, need not to grasp special using method and skill, use escape to have higher success rate; 4, entire equipment has only steel cable from top to bottom, can not produce wrapping phenomena, and is safer, reliable.

The specific embodiment
Embodiment one, referring to Fig. 1 and Fig. 3, the high altitude escape of present embodiment is slow falls machine mainly by support 1, be loaded on rotating drum 3 on the support 1, be wound in steel wire rope on the reel 3, constitute with reel 3 coaxial mounted toothed discs 5, hydraulic pump 6, the pinion 7 that is connected hydraulic pump 6 and toothed disc 5 by rotating shaft 2.In addition, also set up the pressure roller 8 that compresses steel wire rope on the reel 3, hydraulic pump 6 has been set up liquid storage kettle 9 and flow control valve 10.During use, steel wire rope termination and escape personnel's health are connected, and escape personnel's body wt acts on reel 3 by steel wire rope under the effect of gravity, make reel 3 rotations, and steel wire rope constantly is drawn out downward extension, and the escape personnel descends thereupon; And drive 5 rotations of coaxial toothed disc reel 3 rotation the time, and by pinion 7 driving hydraulic pumps 6, hydraulic oil in the hydraulic pump 6 produces corresponding resistance immediately, slow down the rotating speed of pinion 7, thereby regulate the rotating speed of reel 3, negative feedback escape personnel by hydraulic pump 6 can be automatically, drop to ground by eminence reposefully, and its height is determined by length of steel wire rope.Flow control valve 10 is connected on the hydraulic circuit of hydraulic pump 6, by prior adjusting flow control valve 10, the matched size of adjustable decline weight.Described hydraulic pump 6 can adopt quantitative gear pump or constant flow paddle pump.
Embodiment two, referring to Fig. 2 and Fig. 4--Fig. 6, the structure of present embodiment is similar substantially to embodiment one, special feature is to have increased caliper 11, and toothed disc is slim toothed disc 5 ', caliper 11 ranks live slim toothed disc 5 ' and form hydraulic braking with it to connect, and hydraulic pump 6 is linked to be hydraulic circuit with caliper 11.Further control the decrease speed of reel 3 and steel wire rope 4 by the frictional force between caliper 11 and the slim toothed disc 5 '.Between the rotating shaft 2 of slim toothed disc 5 ' and reel 3 single direction ratchet 12 is housed, reel 3 can break away from the resistance constraint of hydraulic pump 6 when making rolling steel wire rope 4.Certainly, more can increase and also be provided with steel wire rope backrush device, make things convenient for the recovery of steel wire rope 4 at rotating shaft 2 other ends.Loose for preventing to go back steel wire rope 4 on the reel 3, the pressure roller 8 outer steel wire rope hold down gags that also are provided with extension spring 13 formations.
In addition, except that using hydraulic pump, also can use air pump to substitute, can produce reverse resistance to reel equally.Certainly, only enumerated some preferred implementation here, the protection category that other is equal to, structure roughly the same all should belong to this patent repeats no more here.
