CN2075527U - High storied building fire escaping device - Google Patents

Abstract

The utility model belongs to a high-rise building fire escaping device, which comprises a rotary drum, a hydraulic element in the rotary drum, a screw transmission pair, an energy storage volute spring, etc. The rotary drum can also be used as a hydraulic cylinder; a compressing piston can also be used as a nut, so the high-rise building fire escaping device has the advantages of simple structure, easy fabrication, small size, low cost, and high safety factor. The volute spring results in the automatic recovery of a wire cable, therefore, the wire cable can be used continuously. Because hydraulic pressure has the characteristics of stable delivery and self-regulation, the high-rise building fire escaping device can drop stably, and don't need manual operation. In addition, all old, young, faint, wounded personnel and articles can land safely. The utility model can be used for high altitude lifesaving, military, mountaineering, entertainment, the physical ability and quality training of children, etc.

Description

High storied building fire escaping device

The utility model belongs to lifesaving appliance.

Device for rescuing from high building during fire is a kind of slow descending device.For at fire or other clutch, people and valuables can be reduced to ground from high vacancy safety, district out of danger, and people have expected utilizing slow descending device, and the people can safety be landed when window etc. is jumped down.At present existing many slow descending devices, but exist problem respectively, conclude to get up can divide two classes: (1) complex structure, parts are many, make time-consumingly, and the usefulness material is more, the cost height.(2) decline process need manually-operated, and can not use continuously, the decrease speed instability, safety coefficient is low.Above-mentioned brucker survival capsule also exists common issue with: volume is big.Be placed in and indoorly or outdoor all can occupy the too many useful space, and not attractive in appearance.Therefore, present existing descending lifeline is difficult to promote the use of.

It is a kind of simple that the purpose of this utility model is to provide, practicality, and volume is little, and decrease speed is stable, can use the lifesaving appliance that cost is lower continuously.

The structure of device for rescuing from high building during fire is as scheming (1):

Central shaft (screw rod) (5) is a fixed axis, on the support that is bolted to stationary support such as building by the axle two ends, shell (1) is fixed on the central shaft, and rotating cylinder (7) and central shaft (5) combine by sliding bearing, and an end end socket of rotating cylinder is a Welding Structure.The other end connects a flat end socket (10) of pulling by a flange, there is sliding bearing at the end socket center, there is the O RunddichtringO in the outside of sliding bearing, the seal cavity that rotating cylinder and end socket form is a compaction cavum just, the double nut of doing of piston (8), be installed on the screw rod (5), there are wear ring and y-type seal ring in the piston outer ring, check valve (3) is contained on the piston, have spout hole on the piston, linear guide (6) is fixed on the end socket of two ends by piston, volute spring (4) the inner is fixed on the central shaft (5), the outer end is fixed on the rotating cylinder (7), and rope (9) is wrapped on the rotating cylinder (7), and the end of restricting is fixed on the rotating cylinder, the other end is equipped with safety harness and places housing (1) outside, Tooth wheel with changeable teeth can be arranged as deceleration device between rotating cylinder and nut.

Practical example:

The lifesaving appliance structure is as figure (1), and each parameter is specific as follows:

D ＝200 mm

d ＝152 mm

l ＝640 mm

B1 ＝80 mm

B2 ＝80 mm

d1 ＝3.8 mm

d2 ＝2.4 mm

t ＝4 mm

d3 ＝64 mm

Compressed media: 20# machinery oil.

Under these conditions, heavy 90KG descends from any height in the 60m with interior people or thing, as long as tie up on the safety harness of cable end, its decrease speed will be stabilized on the interior a certain value of 2.6m/s.

The utility model is compared with existing apparatus, it is stable to have decrease speed, the safety coefficient height, the decline process does not need manually-operated, continuously the many person-times of advantages such as use, compare with same device (sustained height standard), its volume reduces more than one times, and cost reduces more than 40%, has therefore reduced investment and material consumption, the indoor or outdoors space that occupies when installing and using simultaneously is less, outward appearance is the garden column type, and type body rule also can be according to indoor, outer situation, different colours in the spraying, pattern can be beautified the environment, so, have higher practical value.

Claims (1)

1. A kind of lifesaving appliance of being made up of rotating cylinder and screw-drive mechanism, the nut that it is characterized in that compression piston and worm drive is same parts.Snail is installed between fixed axis and rotating cylinder rolls up strong spring, between rotating cylinder and nut, Tooth wheel with changeable teeth can be arranged.
