Abstract

The self-control safety life-saving rope device is formed from cover shell, turning shaft, steel rope, centrifugal block, friction plate, safety hook and chain, etc.. It is characterized by that both sides of the rope drum are respectively equipped with automatic reduction device, and the steel rope is pulled out, the rope drum is rotated, and then the fly-plate is driven by rope drum through turning shaft and rotated, and said fly-plate is equipped with a crank connected with friction plate. When the rotation of the fly-plate is accelerated, the pressure of the friction plate and inner wall of the cover shell is more large by the action of centrifugal force so as to make the rotating speed of the fly-plate to slow down. When the human body jumped down from high is fallen to a certain speed, the fly-plate can be fallen at a uniform speed, and safely landed.

Description

A kind of self-control safety life-saving rope

The invention belongs to the safety life-saving rope in the safety equipment.Safety life-saving rope comprises that case 1, rotating shaft 2, cable wire 3, centrifugal 5, wearing piece 5, safety collude 10, chain 11 is formed by combining safety life-saving rope.

The safety life line is particularly useful on the high buildings and large mansions, and breaking out of fire during people's containment that perhaps other accident caused, breaks away from on-the-spot life preserver in window.

During life line safe in utilization, earlier safety is colluded 10 and be locked in firm place, window place, safety is colluded 10 be buckled between survivor's waist, the people just can jump out window, and the people is just with originally given at the uniform velocity safe landing.When it is characterized in that cable wire 4 is pulled out, drive rope drum 3 and rotate, interlock rotating shaft 2, flying disc 7 rotations drive wearing piece 9 rotations by crank 6.Be equipped with centrifugal 5 on the wearing piece, wearing piece and encloser inner wall produce friction under action of centrifugal force.When cable wire drew soon, the rotation of rope drum was also just fast more, and the pressure of wearing piece and encloser inner wall is also just big more, and rotating speed just slows down, and when the rotation of rope drum was slow, crank 6 separated wearing piece and encloser inner wall under the effect of spring 13, has reduced friction.The rope drum just can rotate soon.It is faster that cable wire just can draw.The rope drum has just reached at the uniform velocity and has rotated like this.The safety life line has overcome when human body lands on skyscraper because the effect of acceleration of gravity is fallen faster and faster, so that causes life danger.Because the effect of safety life-saving rope, make the human body can be according to original adjusted given speed safe falling ground at the uniform velocity.

Below we reach accompanying drawing in conjunction with the embodiments the effect of safety life-saving rope are described in further detail.Fig. 1 is the part sequence number and the title table of comparisons of present embodiment.

Present embodiment is to be inserted in rotating shaft 2 in case 1, puts flying disc 7 in rotating shaft 2, crank 6 and wearing piece 9, centrifugal 5, all is installed on the flying disc 7 before flying disc 7 is inserted in rotating shaft.Good plate washer 12 and the 3 usefulness rivet rivetings of rope drum again, be inserted in rotating shaft then around last hawser 4.Again another flying disc 7 is inserted in the rotating shaft 2.Before flying disc was inserted in rotating shaft 2, same earlier crank 6, wearing piece 9, was installed on the flying disc 7 by centrifugal 5.Then another case is covered.Two cases are fixed by roller 8 with screw then.The other end at case leaves the chain connection holes, with connecting button chain is linked by connection holes and case.Load onto safety at the other end of chain again and collude 10.Load onto safety at the other end of cable wire 3 and collude 10, so just become the lifesaving safety cable.

In order to use safely, the rotating shaft two ends of present embodiment cover end cap 14, recoil the recoil handle 15 that cable wire is used, and are not associated in together with rotating shaft, but as independent instrument, hang over the next door, and are standby to do.

Claims (2)

1. a self-control safety life-saving rope comprises case 1, rotating shaft 2, and cable wire 4, centrifugal 5, friction plate 9, safety colludes 10, and chain 11 waits cooperation to form by dress.It is characterized in that being equipped with in the case rope drum, be wound with hawser at Suo Gushang.Wait the limit at two of rope drum the rotating speed automatic control system is housed.This system and rotating shaft, the rope drum links, and controls the speed that cable wire is pulled out automatically.

2. safety life-saving rope according to claim 1, the system's shaft 2 that it is characterized in that rubbing connects flying disc 7, and crank 6 is housed on the flying disc 7, and crank 6 connects friction plate 9, is equipped with centrifugal 5 on friction plate 9.
