Abstract

The utility model relates to a spider fire saving machine, which comprises a hook, a wire-winding body, a steel cable with both ends respectively fixedly connected with the hook and the wire-winding body, and a person-carrying box body. A shaft of the wire-winding body is erected on a structure frame of the person-carrying box body; a ratchet wheel brake mechanism is composed of a pawl and a ratchet wheel component; the ratchet wheel component is composed of a shaft sleeve which is provided with screw threads and arranged on the shaft, a ratchet wheel ring which is sheathed on the shaft sleeve, circular disks which are made of friction materials and are fixed on both sides of the ratchet wheel, and a handle which is provided with screw threads and matched with the t screw threads of the shaft sleeve. A shaft of the ratchet wheel brake mechanism is connected with the shaft of the wire-winding body in the same shaft line. The utility model can help people in a high building to escape in a fire.

Description

Spider fire lifesaving machine

The utility model relates to mechanical device, is from the cable type draw off gear of high-rise life saving specifically when being used for fire.

Nowadays greatly develop urban construction, high buildings and large mansions are more and more, and are more and more universal.Skyscraper has changed people's life inhabitation and condition of work, brings modern enjoyment and all convenience to people., on the other hand, the security against fire problem of skyscraper also is a great problem that does not obtain fine solution.Disaster hidden-trouble is hard to guard against, and is unavoidable, in case skyscraper catches fire, especially bottom catches fire, and all escape ways such as elevator, corridor all are blocked, and the people who falls into the sea of fire is except the escape of jumping out of the building, not have its meter, unique selection is only left it to chance, and prays extraneous lifesaving personnel's assistance.

The purpose of this utility model is to provide a kind of spider fire lifesaving machine, and it can mannedly reduce to ground from eminence floor safety.

The purpose of this utility model realizes by following design: a kind of spider fire lifesaving machine, comprise tenaculum, winding body, and the steel wire rope that two ends connect firmly with hook and winding body respectively plays the arrestment mechanism of braking action and manned casing to winding body; The pedestal of this winding body is located on the structure stand of manned casing.Described arrestment mechanism is the ratchet-type arrestment mechanism, be made up of the pawl-and-gearing parts, this ratchet part is constructed as follows: threaded axle sleeve is arranged on the axle, and the ratchet snare is on this axle sleeve, the ratchet both sides are fixed with the disk of being made by friction material, with the threaded handle of the threaded engagement of axle sleeve; The axle of above-mentioned ratchet-type arrestment mechanism is connected according to same axis with the axle of winding body.

From above design as seen, the utility model is mainly according to the weave silk principle of hanging of spider, it is that the winding body orientation is opposite with the unwrapping wire source of routine rope lead loop wheel machines such as general elevator, hauling machine, hoist engine, elevators etc. must rely on motor to receive or the unwrapping wire source, and line source (winding body) does not together move with movable body (manned casing), and promptly line source and movable body are in opposed opposite location all the time.The utility model is weaved silk sagging as spider, only depend on self gravitation to descend, and without additionaling power, and line source (winding body) is with movable body (manned casing) operation in the same way in the lump.Therefore, after fire took place, the quilt on the skyscraper enclosed personnel when using the utility model, hook is hung on the firm position of building, and brake activation mechanism, the people is with manned casing, and safe the landing that can freely descend fled from the sea of fire, to reach the purpose of preventing fires and burning body.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is profile of the present utility model (schematic diagram);

Fig. 2 Fig. 3 is respectively the front view (section) and the right view of ratchet-type arrestment mechanism.

Fig. 1 illustrates, and steel wire rope 2 (can adopt other flexible part that a connects) end connects firmly (can adopt the suspension hook frame) with hook 1, and the other end is fixed on the winding body 3, and the axle 4 of winding body 3 is erected on the structure stand of manned casing 5.Fig. 2 Fig. 3 illustrates, and the ratchet-type arrestment mechanism is made up of ratchet 10 and ratchet part, and this ratchet part is made up of threaded axle sleeve 6 (being arranged on the axle), ratchet 7 (snare is on axle sleeve) and threaded handle 8 (with the threaded engagement of axle sleeve); Be fixed with the garden dish of being done by friction material (shim sand canvas) 9 on the both sides of ratchet.When handle during by the revolution of direction shown in the arrow A, it is owing to be moved to the left along the screw thread precession, and ratchet is pressed on the axle sleeve and drives axle sleeve and turn round, and ratchet 10 jumps over along the ratchet gear teeth at this moment.When acting on handgrip, the personnel of taking (install on the handle 8, handgrip takes off among Fig. 3, among Fig. 2 as seen) on the firm termination of power the time, axle sleeve just attempts to rotate by direction shown in the arrow B under the effect of manned casing gravity, because screw thread is arranged, axle sleeve shifts near handle and clamps ratchet, and the ratchet this respect is ratchet 10 preventions, thereby manned casing just rests on the position of rise.During installation, the axle of axle sleeve 6 is coaxial connected mode (axle of ratchet-type arrestment mechanism is connected according to same axis with the axle of winding body) with Fig. 1 axis 4.Ratchet can revolution freely on axle sleeve.

Claims

1, a kind of spider fire lifesaving machine, comprise steel wire rope that hook, winding body, two ends connect firmly with hook and winding body respectively and the arrestment mechanism that winding body is played braking action, it is characterized in that, also comprise manned casing (5), the axle (4) of described winding body (3) is erected on the structure stand of manned casing; Described arrestment mechanism is the ratchet-type arrestment mechanism, form by ratchet (10) and ratchet part, this ratchet part is constructed as follows: threaded axle sleeve (6) is arranged on the axle, ratchet (7) snare is on this axle sleeve, ratchet (7) both sides are fixed with the disk of being made by friction material (9), with the threaded handle (8) of the threaded engagement of axle sleeve (6); The axle of this ratchet-type arrestment mechanism is connected according to same axis with the axle (4) of winding body (3).
