Underground engineering construction equipment and automatic adjusting system for cockpit environment thereof

Abstract

The invention provides underground engineering construction equipment and an automatic adjusting system for the cockpit environment of the underground engineering construction equipment. In actual operation, the air compressor compresses air in a tunnel hole outside the cockpit to increase pressure. Dust, particulate matters and the like are filtered by the air purifier and then enter the air storage tank; the air storage tank plays a role of a buffer area, and air distribution of different pipelines is completed through the first switching valve. Then, the moisture of the first path of air purified by the air purifier is removed through the freezing dryer for the oxygen generator to prepare oxygen, the prepared oxygen enters the oxygen storage tank, and the air inlet amount is adjusted through the second adjusting valve; the purified second path of air directly passes through a first switching valve and a third regulating valve and then enters a cockpit; the temperature adjustment is completed by an industrial air conditioner. The differential pressure sensor is responsible for monitoring the differential pressure inside and outside the cockpit, and air in the cockpit is kept clean through a micro-positive pressure method. Through the arrangement, the problems of high air humidity, high temperature, low oxygen content and air turbidity in the tunnel environment are solved.

Description

technical field [0001] The invention belongs to the technical field of cockpit air comprehensive treatment, in particular to an automatic adjustment system for underground engineering construction equipment and the cockpit environment. Background technique [0002] During the construction of underground tunnels, a large amount of investment in mechanized equipment can greatly reduce labor input in the construction process, reduce labor burden, and improve construction safety and efficiency. In most cases, the tunnel environment has various harsh environmental conditions such as high temperature, high humidity, dust, noise, and low oxygen. The staff can generally improve the working conditions by wearing respiratory masks, fans, and ventilation suits. In high-altitude areas, due to the low oxygen content in the air, under conventional ventilation conditions in the cave, when the oxygen content in the air in the cave cannot meet the needs of normal work, it can be combined wit...
