Description

Lifesaving device for high building

The utility model relates to a kind of skyscraper brucker survival capsule.

Chinese patent CN89216307.4 discloses a kind of " high-altitude lifesaving slow descender ", and it is that white horse with a black mane wheel braked wheel etc. is formed by housing, rope, change gear, driven wheel, travelling gear, the outer fixed gear of internal tooth, follower eccentric.Its major defect is that complex structure, volume are bigger, needs arrestment mechanism.

The purpose of this utility model is at above-mentioned shortcoming of the prior art, and the skyscraper brucker survival capsule that a kind of volume is little, in light weight, have the self-locking characteristics is provided.

The purpose of this utility model is to realize like this, it includes housing, wire rope pulley, steel wire rope, suspension ring, lock hook, particularly it also includes Bevel Gear Transmission mechanism, spur gear transmission mechanism and Worm and worm-wheel gearing, handle is housed on the bevel gear wheel, Bevel Gear Transmission mechanism drives the spur gear transmission mechanism, and the spur gear transmission mechanism drives Worm and worm-wheel gearing, worm gear connects with wheel with wire rope pulley.Housing 21 is a drum shape, and the centre is provided with in the left and right chamber that dividing plate, transmission mechanism and wire rope pulley be divided in housing.The gearratio of bevel gear wheel and bevel pinion is 1:7, and initiatively the gearratio of spur gear and passive spur gear is 1:2, and the gearratio of worm and wheel is 14:1.

Below in conjunction with drawings and Examples the utility model is further described:

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

As seen from the figure, housing 21 is a drum shape, and the centre is provided with dividing plate, and both sides have left and right end cap 11 and 15 respectively, and transmission mechanism and wire rope pulley are contained in respectively in the left and right sides chamber of housing.

Main shaft 17 is contained on right end cap 15 and the case partition by copper sheathing 16, and right end cap 15 is fixed on the right side of housing 21 by screw 12, and wire rope pulley 13 and worm gear 4 are housed on the main shaft 17.Be wound with steel wire rope 14 on the wire rope pulley 13, worm screw 5 connects for axle with passive spur gear 2, and its coupling spindle is supported by axle bed 7 and 27.The effect of pressure bearing 6 is to eliminate the axial friction that the action of worm screw 4 produces, and guarantees that it rotates flexibly.The effect of worm gear is locking, controls freely rotating of main shaft 17.

Initiatively spur gear 3 and bevel pinion 24 are contained on the little axle 19, and little axle 19 is supported by

axle bed

26 and 27, and axle bed 27 is fixed on the case partition by screw 18.

Bevel gear wheel 9 is contained in the left end of main shaft 17 by rolling bearing 6, and the effect of left end cap 11 is to prevent that bevel gear wheel 9 from deviating from.Bevel pinion 10 is contained on the little axle 28, and little axle 28 is contained on the axle bed 7.Little axle 28 and little axle 19 are on an axis.The effect of bevel pinion 10 is the stability of rotation that guarantee bevel gear wheel 9, and guarantees normal engaged, the running of bevel gear wheel 9 and bevel pinion 24.Handle 8 is housed on bevel gear wheel 9.

Suspension ring 1 are contained in the below of housing 21, and load-bearing band and chest measurement band 22 are housed above it.23 is lock hook among the figure, and 25 is guide screw.

The course of work of the present utility model is as follows:

When 1, using this equipment, earlier with lock hook 23 with directly or form such as knot, be fixed on the position or device of indoor external enwergy load-bearing, on colluding, encircle as radiator, pipe or special use.

2, load-bearing band, chest measurement band 22 have been dressed.

3, turning handle 8, adjust working depth, put brucker survival capsule in suitable operating position.

4, begin operation, turning handle 8, bevel gear wheel 9 rotates, and drives bevel pinion 24 and rotates, and bevel gear wheel 9 numbers of teeth are 100, and bevel pinion 24 numbers of teeth are 15, and gearratio is near 1:7.

5, bevel pinion 24 adopts axle to connect with active spur gear 3, rotates together, drives passive spur gear 2 and rotates, and active spur gear 3 numbers of teeth are 40 teeth, and passive spur gear 2 numbers of teeth are 20 teeth, and gearratio is 1:2.

6, passive spur gear 2 and worm screw 5 shaft couplings, during action and worm screw 5 together rotate, the number of worm screw 5 is 2.The rotation of worm screw 5 drives worm gear 4 and rotates, and worm gear 4 is 28 teeth, and worm screw 5 is 14:1 with the gearratio of worm gear 4.

7, worm gear 4 is coaxial with wire rope pulley 13, rotates a circle with commentaries on classics, worm gear 4 during action, and wire rope pulley 13 rotates a circle, steel wire rope certain length that spues, the length that steel wire rope spues is the distance that descends, shake handle continuously and move, just reach the lifesaving purpose to safe landing.

Technical parameter of the present utility model is as follows: 1, high workload degree 70m; 2, safe load 350kg, maximum load 700kg; 3, the about 5kg of weight of equipment; 4, the gearratio of bevel gear wheel 9 and wire rope pulley is near 1:1; 5, decrease speed: shake 60 weeks of handle by per minute, the fastest 27 meters/minute of decrease speed, jogging speed is 9 meters/minute, average decrease speed is 18 meters/minute.

The utility model has the advantages that volume is little, in light weight, but uniform descent has the self-locking characteristics, does not have the possibility of falling fast because of out of control, and can many person-times of continuously uses. Except the lifesaving appliance as the fire fighter, also can be as the life preserver of skyscraper.
