Hydraulic control speed slip bag type high-rise escape device

Abstract

A hydraulically controlled speed-slip bag type high-rise escape device, including an escape device shell, the escape device shell is provided with an upper cover and an escape bag, the inlet of the escape bag is fixedly connected with the upper opening of the escape device shell, and the bottom of the escape bag is provided with an outlet and connected The lower cover is provided with a cushioning cushion inside the lower cover. The escapement housing is equipped with an automatic speed control adjustment device. The automatic speed control adjustment device is provided with a ventilated mask, shoulder safety belt and chest and back safety belt. The automatic speed control adjustment device includes two The oil cylinder is equipped with a piston, a return spring and an oil cylinder telescopic support rod. There is an oil return hole in the piston. The lower end of the oil cylinder telescopic support rod is connected to the friction wheel through a pin shaft. The friction wheel is in contact with the escape bag, and the main gear is also installed on the pin shaft. , The main gear and the auxiliary gear form a gear oil pump. A oil passage and a B oil passage are arranged in the telescopic strut of the oil cylinder. , the pressure in the oil chamber and the oil chamber respectively push the piston in the oil cylinder to run.

Description

technical field [0001] The invention relates to a hydraulic-controlled speed-sliding bag type high-rise escape device. Background technique [0002] In the event of a fire, earthquake, etc., people living in high-rise buildings cannot take the elevator to go downstairs. If you take the stairs to go downstairs, it will take a long time, crowded people, and the stairs have many turns. Therefore, it is ideal to install an escape device on a high-rise building. Existing escape devices Including a pulley type escape device or a pipe type escape device, such as the patent name of the pulley type escape device is: high-rise escape device, the patent number is 2008101208571, including the shell, the sliding rope, the roller, etc., and the use of ratchets, friction plates and pot wheels, etc. The speed-limiting braking device composed of this type of escape device has a relatively complete structure, but the escape device is exposed to the outside, and many people are afraid and pani...

Problems solved by technology

[0002] In the event of a fire, earthquake, etc., people living in high-rise buildings cannot take the elevator downstairs. If they take the stairs to go downstairs, it will take a long time, the people will be crowded, and the stairs will turn many times. Therefore, it is ideal to install escape devices on high buildings. The existing escape devices Including pulley type escape device or pipe type escape device, the patent name of the pulley type escape device is: high-rise escape device, the patent number is 2008101208571, including shell, sliding rope, roller, etc., and adopts ratchet, friction plate and pot wheel, etc. Although the escape device has a relatively complete structure, the escape device is exposed outside, and many people fear and panic about this type of pulley escape device, and dare not use it; the pipe type escape device For example, the patent application number 201610022277.3, the patent name is: an escape pipe, which includes an indoor fixed frame, a curved pipe and a straight pipe. The straight pipe is composed of multi-section double-wall corrugated pipes. A safety hook is installed on the top of the straight pipe, and a descending device is fixedly connected to the safety hook, and a speed controller is wound on the descending device to connect with a safety belt, but the descending device lacks a specific implementation plan
