The inner part of a horizontal groove frame on the upper part of the groove frame is provided with an operating handle. The end of a linkage rod which is driven by the operating handle and a middle fixed pulley are exactly pressed. The outer side of the middle fixed pulley is provided with a turnover cover which is installed on the groove frame. Because the utility model has simple structure, under an emergency situation, the assembly of matching a whole device with the self-help danger-escaping rope for evacuation from high buildings can be completed rapidly. Moreover, the utility model has the advantage of convenient operation and can bring the hope of self escape for people besieged in a fire scene of a high building.

Description

The self-service rope tool of escaping danger of a kind of high building

Technical field

The utility model relates to a kind of high-rise life saving relief utensil, the self-service rope tool of escaping danger of particularly a kind of high building.

Background technology

Along with the continuous expansion of city size, the building in the city is also made higher and higher.Though this has brought prosperity to society, brought comfortable to the mankind.But sporadic fire in high buildings has not only brought some difficult problems to fire department, has brought no small fear and harm also for the household who stays in the high building.In the sporadic fire in high buildings report, there is the people when panic, to take the action of escape of jumping out of the building often, thereby causes the life casualty accident.Therefore, the inventor consider whether can to design a kind of can be in fire, the people that help is in the building high level, besieged by the intensity of a fire provide a kind of device of fleeing from ground from window, so just can make the people that besieged by fire, before fire fighting truck arrives, just can in time break away from the fire danger zone, reduce casualties.

The utility model content

Technical problem to be solved in the utility model provides the self-service rope tool of escaping danger of a kind of high building, when fire takes place, can be hung up this tool of restricting by on the firm rope that puts down on the building top by the besieging personnel, the people can hold the handle of this rope tool, regulate decrease speed voluntarily, slide into ground safely down.

Technical problem to be solved in the utility model can be achieved through the following technical solutions.

The self-service rope tool of escaping danger of a kind of high building is characterized in that: comprise a manual device; Described hand-control device is the truss of one or three limit openings, and is being provided with in the front portion of truss and arranges from top to bottom and three fixed pulleys on same straight line not; Have operating handle in the upper level truss of described truss, the fixed pulley malleation that the trace that operating handle drove is terminal with middle.

Be provided with one in the outside of middle fixed pulley and be installed in renovating on the truss.

Described operating handle is lived by the installing plate on a hinge pin and the upper level truss that is fixed on truss and is connected, and is connected with a return spring between operating handle and truss.

The self-service rope tool of escaping danger of this high building according to above technical scheme proposition, because structure very simply, in case of emergency can be finished the assembling of whole device soon, and operation is also very convenient, can give the hope that brings oneself's escape of besieging in the high building scene of a fire.

Description of drawings

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

Among the figure: 1, rope, 2, renovate, 3, operating handle, 4, fixed pulley, 5, trace, 6, latch, 7, truss, 8, installing plate, 9, hinge pin, 10, return spring, 11, hook.

The specific embodiment

The self-service rope tool of escaping danger of this high building that accompanying drawing provides, it is the individual self-help apparatus of a kind of high building when catching fire, can certainly be as a kind of climbing instrument that utilizes rope.

The self-service rope tool of escaping danger of this high building comprises a manual device, this hand-control device comprises the truss 7 of three limit openings, be provided with on the front portion of truss 7 and arranging from top to bottom and three fixed pulleys 4 on same vertical line not, be fixed with installing plate 8 on the upper level truss in truss 7, operating handle 3 is movably arranged on the installing plate 8 by a hinge pin 9, and a return spring 10 that is connected between operating handle 3 and the truss 7 is being housed on the hinge pin 9.

Have trace 5 on this operating handle 3.

Be provided with one is installed in and renovates 2 on the truss 7 in the outside of middle fixed pulley 4.

The self-service rope tool of escaping danger of this high building, its operation principle is as follows: be located at three fixed pulleys 4 and the rope 1 on three fixed pulleys 4 around the home on the front portion of truss 7, formed the downslide rope ladder or climbed rope ladder.Rope 1 is walked around by the outer sliding surface of top fixed pulley 4, again through the interior sliding surface of the fixed pulley 4 of centre, is laid out by the outer sliding surface of following fixed pulley 4.

For making downslide can control speed, thus in truss 7 operating handle 3 of design band trace 5.When needs reduce gliding speed, as long as the operator is with holding tight operating handle 3, because the rotating counterclockwise of this operating handle 3, will drive the rope 1 on the fixed pulley 4 of trace 5 ends in the middle of pressing, stop this device continuation decline.

Its concrete operation method is: open and renovate 2 on the truss 7, rope 1 is walked around by the outer sliding surface of top fixed pulley 4, again through the interior sliding surface of the fixed pulley 4 of centre, the mode that is laid out sample by the outer sliding surface of following fixed pulley 4 is inserted in, to renovate 2 restores, lock latch 6, just rope 1 and three fixed pulleys 4 have been formed the downslide rope ladder, and form a deceleration downslide system by operating handle 3 and three fixed pulleys 4, when staff is exerted oneself, this operating handle 3, will as bicycle brake device, rope 1 be compressed, this rope tool that glides will slow down slowly, in case unclamp some operating handles 3, will make glides accelerates, and by the fast process of good control the people is delivered to ground reposefully like this.

On truss 7, also be provided with a hook 11, can hang one on the hook 11 and be hung on the suspension member that has the rope element between waist.Perhaps hang with a pedal that has a rope.
