A slow-down device in the hotel's airport guardrail

Abstract

The invention provides a slow-down device in the air-side protective fence of a hotel, which enables people to quickly and safely reach the ground from outside the building when a fire occurs. The slow descending device is characterized in that it includes a roulette, the roulette is sleeved and fixed on the rotating shaft, the outer cylindrical surface of the roulette is provided with a number of guide grooves, the groove bottom of the guide groove is fixed with a guide sleeve, and the outer cylinder of the guide sleeve The surface is processed with external threads, and a slider is installed sliding in the guide groove. The side of the slider facing the guide sleeve is fixed with a guide column, and the other side is fixed with an arc-shaped shoe. The inner arc of the shoe is in line with the above-mentioned The guide post is fixed, and the outer arc surface is fixed with brake pads; the external thread of the guide sleeve is screwed with an adjusting nut, and a gasket is also sleeved on the guide sleeve, and a compression spring is also sleeved on the guide sleeve, and one end of the compression spring passes through the gasket It abuts against the adjusting nut, and the other end abuts against the slider; an annular damping ring is arranged on the outside of the wheel disc. The invention has the advantages of rapid escape, safety and the like.

Description

technical field [0001] The invention relates to an air defense fence, in particular to a slow-down device in an air defense fence of a hotel. Background technique [0002] House construction usually needs to use air barriers, such as window sills, balconies, patios, roofs and other high-altitude places that need protection to prevent people from falling from high altitudes. Especially for hotels, there are many guest rooms and densely populated people, which is particularly important for high-altitude protection safety. Common air guardrails are made of stainless steel, iron and other rods, which only play the role of isolation and have a single function. Some densely populated buildings such as hotels have fires every year that cause heavy casualties, and their fire safety is particularly important. When a fire breaks out, people trapped in the house often have no way of escaping, and some are burned alive. , Some even jumped to their deaths. And the fire extinguisher, f...

Problems solved by technology

And the fire extinguisher, fire hydrant etc. that are configured in the hotel often can't be used in case of emergency, in order to solve this problem, usually install some fire escape devices in the hotel, for example, Chinese patent (notification number: CN201361378) discloses a kind of high-rise fire extinguisher. The escape device, when a fire occurs, first fix the device on the railing of the building through the fixing piece, the escaper stands or sits on the base, manipulates the control switch to make the power mechanism release the steel rope, when the device is about to reach the ground, The escaper makes the device stop by manipulating the control switch. Although the escaper can reach the ground through the device, there are also some problems and deficiencies. For example, the device is an independent device. When a fire occurs, it is first necessary to find the device , in the emergency moment of a fire, whether the device can be found is a problem at first. In addition, the escape in the event of a fire is all about fighting for seconds. First, the device needs to be fixed on the railing of the building, which leads to the loss of time efficiency. The problem, again, when the device is about to reach the ground, the escaper needs to stop the device by manipulating the control switch. It cannot be guaranteed that the escaper can operate the control switch in time during the process of descending through the device, and there are potential safety hazards.

[0003] In order to solve this problem, a kind of guardrail in the air was invented, an escape device was set in the guardrail, and the escape rope set in the device was used to escape. When escaping, the escape rope was pulled out from the guardrail to make escape If the descending speed is too fast, there is a danger of falling, and if the descending speed is too slow, the escape time will be delayed. Therefore, it is necessary to optimize the descending speed of the escaped
