Abstract

The invention discloses a personnel transport vehicle for expanding and excavating inclined shafts, and aims to provide a personnel transport vehicle which is convenient for personnel transportation and safe and reliable. It includes: a frame of steel structure, the two sides of the frame and the bottom arc transition to form an arc surface, which is convenient to put into the inclined well and contact with the wall of the inclined well; the stairs at the bottom are set in the frame; the length of the frame is set There are multiple sets of walking wheels arranged in a straight line on both sides and the bottom of the frame body; the suspension rings arranged at one end of the frame body for connecting traction equipment; The lower parts of the two ends of the frame body are convenient for passing through the guides of obstacles. The invention solves the problems of difficulty in transporting construction personnel for expansion and excavation of inclined shafts and prominent safety hazards.

Description

technical field [0001] The invention relates to the technical field of inclined shaft construction, in particular to a personnel transport vehicle for expanding and excavating inclined shafts. Background technique [0002] At present, the "anti-guided well method" is generally used in the excavation of large cross-sections and long inclined shafts. First, the pilot hole with a diameter of 216 mm is completed from top to bottom by using a raise drilling machine from the upper part of the inclined shaft. After the pilot hole construction is completed, continue to use the raise drilling rig to expand the pilot hole from bottom to top into a pilot well with a diameter of 1400mm, and finally use the "drill and blast method" to expand the deviated well to the design section according to the design section of the deviated well. section. Among them, the first expansion excavation requires personnel to go down to the well, and the manual air drill is used to create holes in sections...
