Problems solved by technology

[0002] In order to enable people in high-rise buildings to escape quickly and safely in emergency situations such as fire, people have designed a variety of life-saving devices. The steel cable (or rope) on the drum is composed of several parts. At the same time, in order to achieve the purpose of controlling the descending speed, friction wheels and brake pads are generally installed on the transmission mechanism of the drum. The transmission chain of the whole device is relatively long and the structure is also Complicated and prone to failure during use
The biggest disadvantage is that no matter what kind of life-saving device, due to the fixed thinking in design, it all uses steel cables or ropes, and most of them are steel cables. Generally, it needs to reach 5-10

Embodiment Construction

[0019] like figure 1 and 2 As shown, a high-rise fire rescue device includes a casing 1, a reel 2 and a transmission mechanism 3 connected to the reel. A groove 21 is set on the reel 2, and a steel strip 4 is wound on the groove 21. The head of the steel strip 4 stretches out from the shell 1 and a ring buckle 41 is arranged at its end. The buckle 41 can be engaged with the fixed hook on the building. Here, in order to ensure the smooth and smooth output of the steel belt 4, two guide rollers 51, 52 are provided at the steel belt protruding mouth position on the shell 1. The width of the steel strip 4 is matched with the groove 21 so that no misalignment will occur during winding, thereby preventing the occurrence of stuck faults.

[0020] In order to achieve the actual required strength, the thickness of the steel strip 4 is 0.4-0.8mm, and the width is about 10mm. At the same time, the approximate calculation formula for the total length of the steel strip is:

Abstract

The invention discloses a high building fire life saving device, which consists of a casing, a winding drum and a transmission mechanism connected with the winding drum. A groove is arranged on the winding drum, a steel belt is wound on the groove, the width of the steel belt is matched with the width of the groove, the head part of the steel belt stretches out the casing, and a buckle is arranged at the end part of the steel belt; the transmission mechanism comprises a worm wheel, a worm screw, a bevel gear and a manual crank, wherein, the worm wheel and the winding drum are axially arranged, the worm screw is positioned on the inner side wall of the casing and meshed with the worm wheel, simultaneously the bevel gear is arranged at one end of the worm screw, the bevel gear realizes the connection with the crank through the mutually meshing with the other bevel gear. The invention overcomes the disadvantages of the prior life saving device that the volume is big, the weight is heavy, and the applicable range is narrow, the invention has the advantages that a drive chain is short, the deceleration adjustment is convenient, the traditional design error zone is broken up, the steel belt with high strength is adopted to replace a cable wire to lead the volume of the whole device to be small and the weight to be light, thus the operation of the tall building with above 50 floors and all age-range people can be met.

Description

technical field [0001] The invention relates to a life-saving device, in particular to a high-rise fire life-saving device. Background technique [0002] In order to enable people in high-rise buildings to escape quickly and safely in emergency situations such as fire, people have designed a variety of life-saving devices. The steel cable (or rope) on the drum is composed of several parts. At the same time, in order to achieve the purpose of controlling the descending speed, friction wheels and brake pads are generally installed on the transmission mechanism of the drum. The transmission chain of the whole device is relatively long and the structure is also It is complex and prone to failure during use. The biggest disadvantage is that no matter what kind of life-saving device, due to the fixed thinking in design, it all uses steel cables or ropes, and most of them are steel cables. Generally, it needs to reach 5-10mm (the diameter of the rope needs to reach more than 15mm...
