Description

From speed-limited skyscraper life line

Technical field the utility model relates to a kind of life line that is used for skyscraper, particularly utilizes speed limiting mechanism to make and is rescued the life line that personnel or goods and materials slowly fall.

The people of background technology life and work in skyscraper can't escape and cause injures and deaths because of running into incidents such as fire, blast, earthquake, abduction sometimes.The casualty numbers of the U.S.'s 911 incidents and domestic all previous fire disaster show, in fact still do not have at present a kind of simple and convenient, received skyscraper rescue or self-help apparatus.

For addressing this problem, once adopted several different methods both at home and abroad in practice, as aerial ladder, helicopter, inflatable packer and some non-normal interim measures.Yet the low cost of considering, security, simple and convenient, self and mutual medical aid and principle such as generally be suitable for, preferred option is still rigging.The professional uses rigging only with hand control frictional force, or realizes slowing down with certain simple apparatus and manual engagement.But said method is only applicable to psychological quality and the good well-trained personnel of fitness, in the nervous chaotic atmosphere that catastrophe takes place, it then is dangerous or even impossible requiring ordinary people, old man, people injured or that faint to only depend on rigging to realize saving oneself or rescue mutually, especially under the floor condition with higher.

The summary of the invention the purpose of this utility model provides a kind of improved from speed-limited skyscraper life line, and it has extensive applicability under the premise that security is guaranteed.

The purpose of this utility model is achieved in that with limiter of speed and the supporting use of life line.What at first use is first limiter of speed, remaining is the supervention limiter of speed, tie up to survivor on the limiter of speed when falling, rope is pulled out in the capstan winch of first limiter of speed and is driven capstan winch and rotate, or from passing through and the rotation of drive sheave between one group of sheave of supervention limiter of speed, the axle of capstan winch or sheave drives accelerating gear system, the high speed shaft of this gear train final stage drives a power consumption device, having one or more brake pads to press drag ring on this power consumption device under centrifugal action rotates, this frictional heat process has consumed survivor's major part decline kinetic energy, falls thereby realized slowing down.This power consumption device also can adopt fluid damping or magnetic damping principle.

The utlity model has following advantage: owing to taked above design, during use operation extremely simple, the survivor only needs one of hanger with limiter of speed to be connected, and jumps out balcony or window gets final product.Described linking can be numerous can letter, as the time from perhaps to the danger and disaster personnel, preferably fasten one's safety belt, and it be connected from the ring of locking and hanging hook with the hanger group; If it is pressed for time, only need put muffetee or catch ring to get final product.Since simple to operate, need the stranger to get involved hardly, and disaster affected people can be rescued mutually.Owing to the negative velocity feedback effect of power consumption device, even two shared limiter of speeds of people, falling speed can obviously not improve yet again.Again because the decline process of this life line does not need manual operation, and the speed of contacting to earth is also lower, so the rush transport goods and materials are also very safe.The use of supervention limiter of speed has improved efficient, after first people lands, and must be with capstan winch with the Suo Chongxin rollback; the people of back can use the supervention limiter of speed to fall along sagging Suo Yici; the machine of neither missing the season do not rely on power supply again, and power supply usually can interrupt when the condition of a disaster takes place.
