An adjustable escape device and its control method

Abstract

The invention belongs to the technical field of escape devices, and in particular relates to an adjustable escape device and a control method thereof, including a lifting mechanism and a control mechanism, and the control mechanism is used to adjust the descending speed of the lifting mechanism. The lifting mechanism includes a hydraulic cylinder, a mounting plate, a guide tube, a compression spring, a lifting platform and a guide rail. The hydraulic cylinder is connected to the ground through the mounting plate, the guide tube is set outside the cylinder body of the hydraulic cylinder, and the compression spring is set on the hydraulic cylinder. The lifting platform is connected with the piston rod of the hydraulic cylinder and can slide up and down along the guide rail. The control mechanism includes a governor, a reversing valve, a controller and an electromagnet. The governor is installed on the lifting platform, the reversing valve is installed on the governor, the controller is installed on the reversing valve, and the electromagnet is installed on the On the top wall of the building, it is used to absorb and fix the lifting platform. The adjustable escape device provided by the invention is easy to use, fast and safe.

Description

technical field [0001] The invention belongs to the technical field of escape devices, and in particular relates to an adjustable escape device and a control method thereof. Background technique [0002] At present, the main escape devices of high-rise buildings can be divided into two types. One is to send the trapped people away from the fire scene along the wall outside the window through the retraction and release of ropes, and the other is to install mechanical escape devices inside the high-rise Evacuate the trapped persons from the danger zone. The existing technologies of these two devices are affected by external environmental factors and cannot meet the requirements of fast, stable and safe escape process under any state. For example, patent 2017113850648 discloses a high-altitude escape device. The device requires a certain reserved space around the building, and the trapped people descend from high altitude to the ground through the conveyor belt. However, this ...

Problems solved by technology

The existing technologies of these two devices are affected by external environmental factors and cannot meet the requirements of a fast, stable and safe escape process under any state.

For example, patent 2017113850648 discloses a high-altitude escape device. The device requires a certain reserved space around the building, and the trapped people descend from high altitude to the ground through the conveyor belt. However, this device is not suitable for buildings with high floors. Low efficiency, vulnerable to weather, and easy to collide with each other during use

In addition, the use of the device also requires the trapped personnel to have high psychological quality and operational skills, so as not to be able to better control the descent speed.

Patent No. 2017111303459 discloses a mechanical escape device, which completely relies on gravity to descend and requires professional training for the user to operate proficiently. It is not suitable for the elderly and children, and it is easy to cause a certain impact on the trapped persons due to the rapid descent.

It can be seen that none of the existing escape devices can meet the needs of fast, simple and safe escape at the same time.
