Abstract

The utility model relates to a distress save-oneself device for high-rise buildings, comprising a structure bracket with a hanging lug, a brake, a fixed pulley and a rope. The utility model is characterized in that the fixed pulley is assembled in the structure bracket through a main shaft, the inner part of the bracket is connected with a V-shaped rocking arm through a rotating shaft, both ends of the V-shaped rocking arm are connected with press wheels, and the rope is wound around the fixed pulley and the inner sides of the two press wheels. The utility model has the advantages that the distress save-oneself device for high-rise buildings is installed on places leading to environment in high-rise buildings, such as windows, balconies, stairs, etc., when people in the buildings can not escape from normal passages due to encountering fortuitous events, such as fire, etc., people can utilize the utility model to save themselves so as to safely and rapidly escape dangerous zones, and the utility model has convenient use, simple structure, small size and light weight.

Description

The high-rise building emergency self-help apparatus

The utility model belongs to personnel on the skyscraper and in case of emergency implements the fire-fighting equipment of saving oneself.

In daily life and work, because some accidentalia or because people off one's guard, the fortuitous events such as the normal breaking out of fire of skyscraper that have personnel to persistence if rescue is untimely or rescue mode is improper, often cause casualties.Present skyscraper does not still have special-purpose lifesaving appliance, and the possessor provides the usefulness of a rope in order to emergency escape for oneself to the greatest extent, still has very big difficulty, especially the elderly or child to be difficult to climb along restricting and descend but in case of emergency implement; And fire department is difficult to be on the scene at the disaster early period of origination, and large-scale lifesaving appliance such as safety ladder is difficult in time play a role.

The purpose of this utility model is: the window, balcony, stair etc. that self-help apparatus are installed on skyscraper lead to extraneous place, when the personnel in the building can not be withdrawn by normal channel because of running into emergencies such as fire, can there be extraneous assistance or extraneous assistance to implement than under the situation of difficult, utilize this self-help apparatus to withdraw the danger zone rapidly, reach the purpose of saving oneself, and it is relatively simple for structure, easy to use.

The purpose of this utility model is achieved in that it comprises band Lifting Lug Structure support, brake apparatus, fixed pulley and rope, its technical scheme main points are: fixed pulley is assembled in the structure stand by main taking out, in structure stand, connect the V-type rocking arm by rotating shaft, the two ends of V-type rocking arm connect pinch roller, and rope is walked around fixed pulley and two pinch roller inboards.

The utility model has the advantages that: its windows, balcony, stair etc. that are installed on skyscraper are led to extraneous place, run into fortuitous events such as fire as the personnel in the building and can not be when normal channel is withdrawn, can utilize this device to save oneself, the safety quick danger zone of withdrawing, easy to use, simple in structure, volume is little, and is in light weight.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the utility model structural principle schematic diagram.

Fig. 3 is that the utility model is installed and used state diagram.

See Fig. 1,2, concrete structure is as follows; On the structure stand 5 of band hanger 6 main shaft 9 is installed, the master takes out affixed fixed pulley 10 on 9, the brake apparatus of main shaft can adopt existing product structure, present embodiment adopts prior art " to connect the ring type centrifugal braking mechanism " (referring to " the up-to-date mechanism atlas " of Tianjin science tech publishing house in March, 1987 publication), the brake hub 4 of brake apparatus is fixed on the main shaft 9, connect braking guide rail 8 on the brake hub 4, install brake silpper 7 on the braking guide rail 8, braking fast pulley 3 is fixedly connected in structure stand 5.As long as main shaft rotates, brake silpper just withstands the braking fast pulley under action of centrifugal force, forms braking, and the size of brake force is directly proportional with the centrifugal force size, i.e. square proportional with the rotating speed size of main shaft.The V-type rocking arm is set in structure stand 5 supports 1, in V-type rocking arm support 1, take out 14 and connect V-type rocking arms 13 by commentaries on classics, two arm ends of V-type rocking arm 13 rotate by wheel pressing shaft 12 and connect pinch rollers 11, and rope 15 is walked around fixed pulley 10 and pinch roller 11 inboards and passed from the hole 2 that passes of structure stand 5.Protecting cover 16 is installed on the structure stand 5 by connector.

Operation principle: see Fig. 2,3, the utility model is suspended in building by cantilever beam/truss structure 17 leads to extraneous place, this moment its state as shown in Figure 3, two ends a, the b freedom of rope are sagging, two ends are equipped with the bondage device, be used for personnel oneself is tied up at rope.When device launched, an end of rope abutted against the below of this device, and it is nearer to lead to extraneous place apart from building, and the personnel in the building are at arm's length; Suitably choose the length of rope, make the other end touch ground at this moment just.In case of emergency, personnel's expanding unit is located near oneself oneself tiing up at rope, confirms to jump out of building after the tie up.Personnel freely hang on an end of rope, drag rope and glide.See Fig. 2, be around on the fixed pulley 10, and implement rope is pressed on the fixed pulley, drive fixed pulley 10 and rotate together by the V-type rocker arm body of a band pinch roller 11b because rope is a circle.Rope, fixed pulley 11b and V-type rocker arm body have constituted the anti-skidding sychronisation of single rope pulley together.Its action principle is; When rope a holds stressed G, pinch roller 11a is subjected to the thrust F of rope, this masterpiece is used for the V-type rocking arm, to produce a moment, this moment finally tightly leans against rope on the fixed pulley 10 by pinch roller 11b, is no more than in personnel's quality under the situation of certain limit, just can guarantee to have only an end stressed and under the situation that the other end freely dangles at rope, with no relative slip between the fixed pulley, thereby realized that rope drives fixed pulley and rotates this purpose.Fixed pulley is coaxial with arrestment mechanism.When rope drives the fixed pulley rotation, also will drive arrestment mechanism and together rotate; Similarly, when arrestment mechanism produces braking effect, also braking effect can be passed to the pulley mechanism of taking out altogether, and then personnel are descended form braking, the speed of causing to fall and break remains on a metastable state, thus safely dropping.When personnel are suspended on rope a end (see figure 3) safe falling to ground, must untie rope immediately away from the scene of the accident.Rope has designed length in advance, and this moment, the b end of rope arrived just near the lifesaving appliance place, if building with also having personnel to wait to rescue in the layer, can be about to oneself tie up the end in the b of rope certainly, implements to save oneself according to said method.This self-help apparatus rope a, b two ends have interchangeability, and personnel tie up at rope a end or b end, and effect is the same.So design is in order to improve utilization ratio of device, to make it can repeatedly play a role with in an accident.
