Abstract

The utility model relates to a high altitude self-falling device for rapid escape of fireman or people trapped in high-rise building as well as rapid and safe descending of helicopter fireman. The utility model is characterized in that the device is sleeved on the external periphery of a rope body; a squeezing roller which can slide up and down along an oblique track is arranged in a distributed speed limiter. When the device slides down, the squeezing roller tightly grips the rope and drives the device to slide down rapidly by means of the weight of body. As an ideal high altitude self-falling device, the utility model has the advantages of reasonable structure, simple technology and high practical value.

Description

The high-altitude self-landing device

Technical field

The utility model belongs to fire fighter's high altitude rescue, the high-altitude self-landing device that escape and Landing Personnel Helicopter's safety descend.

Background technology

It all is through special training that the prior art high and medium descends, and both hands control rope descends, and have only the personnel of special industry to realize, but falling head is limited, and certain unsafe factor is arranged.

Summary of the invention

The high-altitude descends, and both hands control rope has very big unsafe factor, and the frictional force that the utility model adopts squeegee roller to produce when powerful extruding descends to rope need not operation, the mode of falling certainly of safety by what body weight pulling self-landing device descended.

The utility model is achieved in that rope is with a parent outward, and the speed limit body is arranged on the parent, and the speed limit body is provided with the intilted speed limit track in upper end, and the storehouse, wheel road of dress squeegee roller is arranged, and squeegee roller is moved up and down by bearing pin control, and bearing pin is contained in the speed limit track.When human body pulling self-landing device descended, squeegee roller took speed limit track upper end to by bearing pin, and rope is finished extruding, produces frictional force, after body weight overcomes partial frictional power, and safety decline at the uniform velocity.The size decision decrease speed of squeegee roller.

The squeegee roller surface of above-mentioned self-landing device can be the annular knurl face, toothed surface.The shape of squeegee roller can be cylindrical, spherical, oval.Bearing pin can be a square column type, cylindrical.

The utility model adopts extruding to produce friction, and by the mode of deadweight overcome friction, performance is safe and reliable.High-altitude self-landing device technology is simple, and cost is low.

Fig. 2 is the profile of high-altitude self-landing device shown in Figure 1

The specific embodiment

As Fig. 1, Fig. 2 high-altitude self-landing device is by the parent 1 that is enclosed within the rope periphery, the speed limit body 2 that is located on the parent 1 is formed, the intilted speed limit track 3 in upper end is arranged on the speed limit body 2, wheel storehouse, road 6, wheel storehouse, road 6 and parent 1 are penetrating, and the squeegee roller 5 by bearing pin 4 controls is housed in the wheel storehouse, road 6, and bearing pin 4 is contained in the speed limit track 3, and be provided with lower hanging hole 7, rise hanging hole 8.

Human body is hung on the lower hanging hole 7 by safety belt, and parent 1 moves down, because 5 pairs of ropes of squeegee roller have light pressure, squeegee roller 5 will be driven by rope, takes speed limit track 3 upper ends under the control of bearing pin 4 to, and rope is pushed, produce frictional force, body weight overcomes partial frictional power safety and descends automatically.Decrease speed is the size decision of squeegee roller.After the high-altitude self-landing device was finished decline, as long as self-landing device is upwards touched, squeegee roller 5 was just got back to speed limit track 3 lower ends, removed the extruding to rope, by being located at the tiny rope traction that rises hanging hole 8, got back to original position fast easily, used repeatedly for many people.
