Abstract

The utility model discloses a device for descending from high altitude, which controls the descent speed and is suitable for the occasion that when the fire happens in a tall building and the passageway downstairs is blocked by fire, and people can use the tool to escape from the danger safely and quickly. In general, the device for descending from high altitude can be used from the second floor to the fiftieth floor. The utility model is composed of a control device, a braking device, and a buffering device. According to different design requirements, the device for descending from high altitude can load one person or more than five persons and articles to descend from the tall building to the ground surface. The utility model has the advantages of small size, low cost, safety, and simple use.

Description

Device for descending with control from high altitude

The utility model relates to a kind of high-altitude landing-gear, particularly on skyscraper when in danger (as fire) but safety is out of danger rapidly.

Present building is all to high-level development, and stair have become people to go up the only way which must be passed downstairs with elevator like this, and still, when building caught fire, this only way which must be passed tended to be sealed by fire, and people have to await one's doom on high-rise building.Someone jumps off from window under the pressure of the intensity of a fire, burns though exempt from fire, be smashed to pieces.

Task of the present utility model provides a kind of instrument that people's safety from the skyscraper is landed.

Task of the present utility model is finished as follows; Thin steel rope (or steel disc) is wrapped on the metal runner.The rotatory force of runner and brake force derive from landing person's gravity, the summation of these energy be exactly landing person potential energy aloft, energy consumption has mainly produced heat energy by the friction of two friction plates and runner.In order to control decrease speed, designed a brake apparatus and braking controlling organization, by the distortion of four bar hinges, controlled the pressure of friction plate and runner, just controlled fricative brake force.This brake force is directly proportional with landing person's quality, reaches the effect that runner self-locking or speed change are rotated.Control loop pulls down, and runner just changes (decline).Control loop unclamps, just braking of runner (stopping landing).Draw the size of control loop power just can control the speed of decrease speed.In order to prevent to impact influence, seal in a buffer spring to human body.The utility model uses very convenient, and volume is very little, and is safe and reliable.

Below with reference to accompanying drawing utility model is described in further detail.

Fig. 1 is a cutaway view of the present utility model.

Fig. 2 is a rough schematic view of the present utility model.

See figures.1.and.2, length greater than or be bordering on the thin steel rope (or steel disc) (15) of falling head, fasten on suspension hook (16) for one, the other end is fixed on the runner (2) with bridge screw (1).Runner (2) can be gone up at little axle (3) and rotate.Little axle (3) constitutes a hinge linkage by hinge (4) and brake bar (5) and four bar linkages (7).When using the utility model, suspension hook (16) is fixed on the object in high-altitude (on steam heating pipe and running water pipe), this power is by F ₁Finish.The weight mg of landing object acts on the following hinge (9) of four bar linkages (7) by waistband (12), spring (11), steel cable (or steel disc) (10).The L size shortens like this, the then a pressure increase of order, and runner (2) is braked or the rotation of slowing down; When acting on a F downwards with hand or pin ₂Power is when control loop (13) is gone up, and then the L size increases, and then a pressure of ordering reduces or disappears, and runner (2) is released, faster rotational speed.If friction plate (6) and four each position size Selection of bar hinge (7) is reasonable, will make decrease speed control steadily, it is very little that behaviour does power.Brake bar (5) is gone up and with fixture (14) friction plate (6) is fixed as one.The position of friction plate on two brake bars (5) and the length ratio of four each bar of bar hinge (7) have determined the brake force and the F that are caused by mg ₂The size of the control that causes.Its medi-spring (11) connects the form that can take insurance suspension hook (16) with landing person, also can use the form of waistband, and spring mainly has been the effect of energy-absorbing buffering.Weight and descent altitude according to difference landing thing require design, generally can cut 1 people on two floors to five, ten floors or on the higher floor or more than 5 people and some article drop to ground, each part safety coefficient is all got more than 4～8.
