Description

Controllable intelligent building escape device

technical field

The utility model relates to a building escape device.

Background technique

Fire has brought more and more threat to people's life and property safety, especially for the resident of high-rise building, once breaking out of fire will be difficult to escape. An escape device that helps people escape smoothly can save many lives. There are few types of existing building escape devices, usually equipped with high-power motors and variable speed and control devices, which are expensive, bulky, heavy, inconvenient to carry and use, and the effect of saving people and escaping needs to be improved.

Utility model content

The purpose of the utility model is to provide a controllable intelligent building escape device, which is small in size, light in weight and easy to operate.

The technical solution of the utility model is as follows: a controllable intelligent building escape device, including a lifesaving rope and a safety belt at the end of the rope, characterized in that the lifesaving rope goes around the rope wheel and is connected to the winch; The rope wheel is installed on the horizontal central shaft, and the two ends of the central shaft are respectively fixed on the left end cover and the right end cover; the upper end of the left end cover is connected with buckles, and the rope wheel is also connected with the gear reduction mechanism on the central shaft.

When in use, buckle the buckle to the pre-fixed support or the window frame and the guardrail of the window or balcony, then put the safety belt on the body, throw the winch reel out from the window, and then people climb up from the window. Then, the person can slowly descend along the outer wall under the deceleration effect of the gear reduction mechanism, and escape smoothly. After one person escapes, the second person and subsequent escapers will lift the lifeline to the window, put on the safety belt and escape.

Compared with the prior art, the beneficial effects of the utility model are:

The mechanical deceleration gear mechanism connected with the lifeline automatically decelerates the falling of the human body. Compared with electric control, its structure is simple, small in size, light in weight, easy to operate, and does not depend on external mains power, its reliability is stronger, and its chance of escape is higher.

The specific composition of the above-mentioned gear reduction mechanism is: three planetary gears are fitted on the side edge of the sheave, the outer teeth of the planetary gears mesh with the inner gear, the inner gear is fixed on the left end cover by bolts, and the outer teeth of the planetary gears are engaged with the inner gear. The outer teeth are also meshed with the outer teeth of the sun gear on the right side of the rope wheel. The sun gear is installed on the central shaft. , the outer side of the turntable is covered with a friction cover, and the friction cover is fixed on the right side of the internal gear.

The working principle of its deceleration is:

Under the gravity of the human body, the life-saving rope drives the rope wheel to rotate, and the outer edge of the rope wheel drives the planetary wheel to revolve around the central axis. At the same time, the planetary wheel drives the sun gear meshing with it to rotate around the central axis. Fixedly connected, the friction block in the groove of the turntable also rotates. Due to the centrifugal force, the friction block is thrown out of the turntable, and the friction block and the friction cover generate friction, thereby realizing the deceleration function of reducing the descending speed.

This gear reduction mechanism, through mechanical gear transmission and friction braking, simply and effectively realizes the braking deceleration function without external energy, and has a simple structure and reliable operation.

A hovering device is also provided below the above-mentioned sheave. The specific composition of the hovering device is: a horizontal shaft sleeve is fixed on the left end cover, a rope threading shaft is housed in the shaft sleeve, and both the rope threading shaft and the shaft sleeve are equipped with The vertical through hole for the end of the lifeline to pass through, the right side of the rope threading shaft is provided with an electromagnet fixed on the right end cover, and the electromagnet is connected with electricity.

In this way, if it is found that there is an unexpected situation below during the descent and it is not suitable to descend, the electromagnet can be controlled by the hand-held remote control to remotely control the receiving circuit to work, so that the electromagnet is charged, and the rope-threading shaft is attracted to the right, so that the vertical direction of the rope-threading shaft If the through hole deviates from the position of the vertical through hole of the shaft sleeve, the lifeline will be stuck, and the functions of braking and hovering will be realized. Therefore, the escape device is more intelligent and controllable, and has higher safety.

Moreover, there can be multiple handheld remote controllers, which can be controlled by the escapees themselves, or controlled by ground personnel, so as to realize multi-person control. The danger caused by the hovering caused by the panic and the escaper not performing the hovering operation is avoided, so that the safety and reliability of the escape device are further improved.

A guide wheel is arranged below the above-mentioned rope wheel, and the lifesaving rope is connected with the safety belt through the rope groove on the guide wheel.

In this way, the sliding of the lifeline is more stable and reliable.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
