Description

The slow machine structure of falling of life-saving

Technical field

The utility model relates to and a kind ofly slow falls the machine structure, specially refers to a kind of slow machine structure of falling of life-saving, is a kind of security tool that is useful in restriction landing speed on the rope, and it can be used as the high building urgent escape device and uses.

Background technology

High building stands in great numbers in the current city, can be convenient to escape when avoiding fire in high buildings to take place, be provided with in high building that slow to fall machine be wherein indispensable urgent escape device, slow fall machine and become the security tool of saving one's life, its operating position as shown in Figure 1, be a kind of slow descending device 100, this slow descending device 100 is suspended on slow under the support 101 by a support 101 that is fixed on wall, by hook and falls machine 102, and fallen fastening belt or the band 104 that machine 102 ropes rope 103, tight or rope system is combined in rope 103 ends and formed by slow; Wherein, slow fall machine 102 inside and have the downhill race speed that reducing gear can limit rope 103, and can give braking deceleration in good time, and band 104 encompasses snare 104a, and snare 104a is provided with one and brings ring 104b together to be used to bring together snare 104a.The correct using method of slow descending device is that snare 104a is placed in chest and clips to or clip the oxter, both sides, utilize again and bring ring 104b together snare 104a is brought together in the front, to reduce the gap between snare 104a and chest, wait to bring together finish after, just can delay and fall action.In slow process of falling, the user jumps out of high building and is unsettled, at this moment all relies on slowly to fall the landing speed that machine 102 supports human body weights and limits rope, and personnel can be delayed reduce to ground and obtain safety.The slow machine that falls of prior art, its inside mostly is complicated parts greatly and constitutes, the utilization gear, the cooperation of pulley is delayed rope to fall, to reach the deceleration requirement, therefore the slow machine that falls is the fire important escaping tool of saving one's life when taking place, but owing to use probability not high at ordinary times, need often regularly to detect maintenance again, Guan Yong slow mechanism's complexity of falling machine simultaneously, not quick detachable and assembling, so the testing staff need spend many times and does and detect maintenance, many times of waste on assembling procedure, cause the testing staff to simplify test item for saving time, feasible detection becomes a mere formality, in case when the fire alarm disaster takes place, if owing to slowly fall the machine fault or in fact can not be used, to lose the chance of escape help, this is an important disadvantages.

The utility model content

Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provide a kind of assembling easily, structure is simple, be difficult for breaking down, and possesses the slow slow machine that falls that falls function again.

Machine falls in described in the utility model delaying, and is achieved by following technical proposals, and a kind of life-saving is slow to fall the machine structure, comprises: base, and place is provided with one to projecting inward main shaft in the middle of it, and the top has a buckle ear, and several pulleys are established by a location plate holder in the bottom; Reel is located on the main shaft by bearing holder (housing, cover), and the one end is the capstan winch that inner face has the on-slip line, the rope of capstan winch clamping pile warp, and with the mutual interlock of rope, the other end of capstan winch be provided with the annular rotating shaft; Planetary gear has several and is arranged in the rotating shaft of above-mentioned annular; The annular rack rails, bolt is located on the base, and frame is outside planetary gear, and teeth are meshed with each annular planetary gear in it; Brake disc borrows bearing holder (housing, cover) to be located on the main shaft, and the one end has central gear and is engaged in each planetary centre, and the brake disc lateral margin is equipped with a plurality of breaker slots, is provided with brake(-holder) block in the breaker slot; Bottom is adjacent to the side of annular rack rails, and cover and keeps appropriate gap with the braked wheel outer rim and do not contact outside braked wheel; And enclosing cover, bolt is located on the base main shaft and with above-mentioned reel, planetary gear, annular rack rails, brake disc, bottom cover, its outer rim is provided with tenon set on locating hole and the base and cooperates, and the enclosing cover root edge is provided with a breach makes above-mentioned location-plate on the base and the pulley be located to exposing outside.

A kind of life-saving is slow to fall the machine structure, it is characterized in that: base is provided with the keyhole of several annulars and the tenon of annular, and keyhole is that the perforation that penetrates annular rack rails after passing for plug again, the keyhole back of bottom cooperate fixing with nut; It is interior fixing that tenon is embedded in the locating hole of enclosing cover.

Derived by pulley with rope pile warp capstan winch during enforcement, when rope pulling capstan winch, reel can drive planetary gear and rotate in the rack rails that goes in ring, and is engaged in central gear between planetary gear this moment and is force-appliedly to make the brake disc interlock and rotate; After the brake disc rotation, brake(-holder) block promptly is subjected to centrifugal action and covers inwall generation resistance to extending out to arrive to, and utilizes the rotating speed of the resistance limits reel that is produced, and falls action so that rope delays.

Of the present utility modelly slow fall the machine structure following beneficial effect arranged compared with prior art:

Structure simple, be easy to tear open group and maintaining;

When the frictional resistance that the speed of rope landing is faster, produced between brake(-holder) block and bottom also just big, the landing speed of rope can be limited, the speed that makes personnel's landing reaches safe landing in prescribed limit;

3. planetary design makes that the transmission between brake disc and capstan winch is more steady; can disperse the instant impact between gear and gear; avoid slip teeth or collapse the tooth situation taking place, and the moment shearing that can disperse rotary gear shaft to bear, to guarantee slow safe operation of falling machine.
