Abstract

The invention discloses an underground pneumatic transfer device, which comprises a rotary fixing device, a central pillar and a lifting rod; the rotary fixing device is connected with the bottom part of the central pillar; the top end of the central pillar is provided with a fixing ring, and the lower end of the central pillar is provided with a pneumatic motor and a worm speed reducer; one end of the pneumatic motor is connected with an operating valve through a pipeline A and a pipeline B; the air inlet of the operating valve is connected with a high-pressure gas source; the other end of the pneumatic motor is connected with the worm speed reducer; the output shaft of the worm speed reducer is connected with a roller; a steel wire rope is arranged in the roller; the tail end of the lifting rod is provided with a leading sheave, and the front end of the lifting rod is provided with a lifting tackle; the steel wire rope penetrates through the leading sheave and the lifting tackle. According to the underground pneumatic transfer device disclosed by the invention, energy is provided by high-pressure air by replacing electricity, so the use safety is enhanced, and the use range is broadened.

Description

technical field [0001] The invention relates to the field of downhole transfer, in particular to a downhole pneumatic transfer device. Background technique [0002] Most of the underground transfer devices in the prior art use electric energy as the energy source, which is unable to prevent dust and explosion, has a small safety factor, and is not suitable for working under harsh working conditions such as open air, underground, and heavy water vapor; The degree of danger during operation. Therefore, it is necessary to design a downhole pneumatic transfer device with a high safety factor and a wide application range. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a downhole pneumatic transfer device with simple structure, high safety factor, and suitable for special environments. [0004] The present invention is realized by the following technica...
