Mine supporting equipment for geotechnical engineering

Abstract

The invention discloses mine supporting equipment for geotechnical engineering, and belongs to supporting equipment. The mine supporting equipment for geotechnical engineering comprises a base; and the middle of the upper end of the base is fixedly connected with a fixed column, and the upper end of the fixed column is connected with a supporting column in a sleeved mode. By arranging the base anduniversal wheels, the mine supporting equipment is conveniently moved in a mine and moved to certain special positions for supporting advantageously; a pushing mechanism drives a moving mechanism tomove towards the two sides of a worktable, thus a first supporting rod drives a movable block to move downwards, the supporting column moves downwards, the movable block drives a second supporting rodto retract while moving downwards, and the second supporting rod retracts, so that a second arc-shaped supporting plate also retracts for folding, the size of the space occupied by the whole equipment is greatly decreased, and the equipment is conveniently placed in the mine; and through arrangement of an air purification device, the air quality in the mine is improved, and the situation that people breathe in harmful air, and consequently bodies are influenced is prevented.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, more specifically, to a mine support device for rock engineering. Background technique [0002] With the development of various ownership engineering construction enterprises and the breaking down of barriers to cross-regional operations, the geotechnical engineering market is already in a state of complete competition. The undertaking of geotechnical engineering projects is mainly realized through public bidding activities. The degree of marketization in the industry is relatively high, and the market concentration is relatively low. my country's geotechnical engineering industry has the characteristics of large number of enterprises and small scale. According to the "2013-2017 China Geotechnical Engineering Industry Development Prospects and Investment Strategic Planning Analysis Report" statistics, there are more than 300 companies engaged in dynamic compaction business in my country a...

AI Technical Summary

Problems solved by technology

[0003] In the current construction of geotechnical engineering, especially in the mine, the support equipment inside the mine is generally fixed in the cave, which is not easy to move, and it is inconvenient to carry out support at any time when supporting some special positions. Support, and the existing support equipment is large in size and takes up a lot of space. It is not convenient to place inside the mine, and the air quality inside the mine is not good. If it is not improved, long-term inhalation will affect the body
