Abstract

The invention discloses a multi-degree-of-freedom in-laneway dust catcher which comprises a rotary hydraulic cylinder (7), a swing hydraulic cylinder (5), a lower support disc (4), an upper support disc (2), retractable hydraulic cylinders (3), a telescopic hose (9) and a dust catching cover (1), wherein a base (6) is arranged on the rotary hydraulic cylinder, the lower support disc is arranged on the base, one end of the swing hydraulic cylinder is connected with the base, the other end of the swing hydraulic cylinder is connected with the upper end of the lower support disc, the upper support disc is arranged at the upper part of the lower support disc, the upper end of the telescopic hose is movably connected with the dust catching cover, the lower end of the telescopic hose is movably connected with a dust exhausting pipe (10), the retractable hydraulic cylinders are symmetrically arranged, and a guide sleeve (8) is arranged between the upper support disc and the lower support disc. The multi-degree-of-freedom in-laneway dust catcher provided by the invention has a compact structure, is convenient to manufacture and mount, is reliable and durable, occupies a small space, realizes that the dust catching cover can be stretched, lifted and steered in positions according to requirements, not only ensures that the operation of other excavating equipment inside a laneway is not disturbed, but also improves the dust catching efficiency of a dust removal system in laneway excavation.

Description

technical field [0001] The invention relates to a multi-degree-of-freedom roadway dust-collecting device used in roadway excavation working faces and tunnel construction working faces. Background technique [0002] With the development of my country's industry, the demand for energy and underground space continues to increase, and the level of mechanized construction of coal mining and underground engineering continues to increase. Dust is one of the main pollutants in mine excavation and tunnel excavation. There are more and more underground projects being constructed, and dust poses a great threat to the normal operation of on-site construction machinery and the health of workers. The efficiency of dust removal in roadway depends on the two key technologies of dust capture and dust removal. At present, there is no corresponding dust capture device in the dust removal system in roadway excavation. Contents of the invention [0003] The purpose of the present invention is ...
