Description

Apparatus as body protector or for lowering persons from high building

The utility model belongs to lifesaving appliance.

In the prior art, domestic have a kind of high-altitude lifesaving slow descender, is that a end with a belt continues to pass through the ground that hangs behind a plurality of holes on the block plate, and stephanoporate steel plate is contained in window or balcony limit, and the people who needs to descend ties up to the other end of belt.During decline, utilize the frictional resistance that produces between belt and the steel plate to reduce decrease speed.When rescuing the masses, can hold an end on the vertical ground of belt with control decrease speed, trained fire fighter, self controllable pulling out of dangerous places by the ground staff.But common people can't save oneself with it, simultaneously, uses this descending lifeline, and belt easily is worn.

The purpose of this utility model is that to manufacture and design a kind of structure simpler, safe and reliable, can operate for descender oneself, is easy to the slow descending device controlling reduction of speed and hover, and in addition, it also can be used for work high above the ground.

Design of the present utility model and technology contents are: main hoist cable one end is tied up to building fall on the robust member at people place; The other end ground that hangs, the descender takes and handles slow descending device and glides along main hoist cable.Main hoist cable can be with one or two, also can be with many.Slow descending device mainly is made up of several parts: substrate, be contained in pulley speed reducing mechanism, the bar arrestment mechanism on the substrate and take advantage of mounted mechanism.

Substrate: the alleged substrate of the utility model is the high hard plate of a bulk strength.The sheet stock of not holing in the high-altitude lifesaving slow descender of above-mentioned prior art also belongs to substrate, and substrate of the present utility model can also be used the hard aluminium alloy plate, other metals or other materials manufacturing.

Pulley speed reducing mechanism: many fixed axis perpendicular to substrate are housed on substrate, and these axles are uniform substantially, and pulley, spring and regulating part are arranged on the every axle.Regulating part can be with multiple nuts and washers or similar parts.The fixed axis spindle nose has screw thread.Screw nut, promote packing ring compression spring, the pressure of spring is close on the substrate pulley.

(number of walking around pulley can be decided by actual conditions to make main hoist cable walk around each pulley, as: descender's weight, spring to pressure size of pulley etc.), when slow descending device and descender's weight puts on main hoist cable by pulley, between main hoist cable and the pulley friction takes place and drive rotation, the existing sliding friction of main hoist cable and pulley room also has rolling friction.Simultaneously, a side of pulley and substrate, another side and spring also rub.For the pulley two sides being rubbed evenly and spring not being rotated, can between pulley on the every axle and spring, be inserted in the baffle plate that has a double wedge, and, bottle up the double wedge of baffle plate at the anti-bull stick that be equipped with on the baffle plate next door and axle is parallel, rotate with the prevention baffle plate.At this moment, a side and the substrate of pulley, another side and baffle plate rub.The main hoist cable of walking around behind the pulley hangs down naturally, by the bar arrestment mechanism ground that hangs again.

Bar arrestment mechanism: bar and brake bar are housed in the substrate bottom.Brake bar one end has rotating shaft, be loaded on the axle bed that is fixed on the substrate inferior horn, thereby brake bar can rotate around the shaft, can with fixing bar

Close the main hoist cable that clamps by wherein, further reduce reduction of speed even brake fully and hover.

Therefore, slow down and hover can be by tightening regulating part in the decline of people and slow descending device; Main hoist cable is many around a little pulleys; Increasing the methods such as folder power that put on above-mentioned two bars realizes.

Take advantage of mounted mechanism: can form by safety belt and seat board, also can below substrate, hang one can be manned pocket.Safety belt can tie up to the substrate upside.Seat board is connected under the substrate.

In addition, the substrate upper limb can be equipped with the guide collar of main hoist cable.Guide collar is a helical form, and the less reinforcing bar of available diameter forms around 2 to 3 circles.The number of dress guide collar is identical with the radical that uses main hoist cable.

Description of drawings:

Fig. 2 is the local side-looking enlarged drawing of Fig. 1;

Fig. 3 is that the utility model is equipped with the schematic diagram when the rope device;

Fig. 4 is the utility model schematic diagram in use;

Concrete structure and an embodiment of providing below in conjunction with accompanying drawing specify the utility model:

As shown in Figure 1, 2, the utlity model has substrate (1), take advantage of mounted mechanism, pulley speed reducing mechanism and bar arrestment mechanism.Many (present embodiment is 12) fixed axis (2) are equipped with in pulley speed reducing mechanism on substrate, fixed axis has pulley (3), baffle plate (7) spring (4) and regulating part perpendicular to substrate on the every axle.Regulating part can adopt nut (5) and packing ring (6), compresses baffle plate and pulley by the compression spring.The baffle plate next door also has the anti-bull stick (8) parallel with axle, stops baffle plate to rotate.Main hoist cable (14) (present embodiment the is 2) guide collar of packing into (13) (present embodiment is 2), respectively walk around several (present embodiment is 6) pulley then, again from the substrate bottom form between the bar (9) of bar arrestment mechanism and the brake bar (10) by after the ground that hangs.The descender shirtfront does not have the one side of pulley towards substrate, and safety belt (12) is walked around back to another oxter fastening substrate from oxter, one side, and one holds bar, and another hand hold the handrail simultaneously bar and brake bar clamp main hoist cable, just can brake fully.At this moment lift pin and ride on seat board (11), just the descender can be together with slow descending device unsettled fully (as Fig. 4), also can below substrate, hang one can be manned pocket, allow the descender take in pocket.Promptly carrying the descender slowly descends.After arriving ground, people upstairs can utilize main hoist cable that slow descending device is retracted upstairs and re-use.

In order to help old and weak people, women and children's safety to descend, can fall the people place be equipped with handle and rotating cylinder etc. around rope device (16) (as Fig. 3), assisted suspension cable (15) one ends are tie wrapped to around Suo Qishang, the other end ties up on the substrate.People upstairs holds the reduction of speed that handle can help to control the descender, and available again later on slow descending device being pulled on again around the rope device used.But also can directly replace around the rope device by people upstairs with pulling assisted suspension cable.

The utlity model has following advantage:

(1) can supply descender's Self-operating, automatic control decrease speed and hovering.

(2) main hoist cable wearing and tearing are littler, if use two or more hoist cable, security is better.

(3) if use two or more hoist cable, direction is stable during decline, removes barriers in being convenient to descend.

(4) structure is simpler, is easy to apply.

(5) can be used for saving oneself or work high above the ground among a small circle, also can be used as " dropping from the air " recreation. If additional a few components or equipment, can be applied even more extensively outside building wall whitewash and stone, explosion are played in repairing, cliffside, the work high above the ground such as gather medicinal herbs.

Therefore, group or individual per capita can be for subsequent use. Luxurious hotel preferably is for subsequent use.
