Mine down-hole circular arc arched splitting upper turn-over type water protecting gate

Abstract

The invention belongs to the technical field of a water discharging strobe in an underground laneway of a mine and in particular relates to a circular arched dividable upper-turning waterproof strobe in the underground of the mine, which solves the problems that the prior waterproof strobe can not meet the need of the mine. The circular arched dividable upper-turning waterproof strobe comprises door frames and door leaves; each of the door frames comprises an upper door frame, a lower door frame, a left door frame and a right door frame; the upper door frame and the lower door frame have the same circular arched shape; each of the door leaves comprise an upper door leaf and a lower door leaf which are connected by a connecting bolt I; the cross sections of the upper door leaf and the lower door leaf have the circular arched shape; the radians of the upper door leaf and the lower door leaf are consistent with the radians of the upper door frame and the lower door frame; the top of the upper door leaf is hinged with the upper door frame; the upper door leaf is connected with the front end of a hydraulic jack for opening and closing the door; and the rear end of the hydraulic jack for opening and closing the door is fixed relative to the upper door frame. The circular arched dividable upper-turning waterproof strobe has the following advantages of wide application range, large bearing capacity and large door area which can meet the use requirements of the large section of the laneway, simple machining and manufacturing process and low machining expense.

Description

technical field [0001] The invention belongs to the technical field of water discharge gates in underground tunnels of mines, and in particular relates to an arc-shaped, separable and upward-turning waterproof gate in underground mines. Background technique [0002] Setting waterproof gates in mine underground roadways is one of the water prevention and control measures generally adopted in mines at present. However, with the continuous improvement of mine mechanization, the continuous increase of mining equipment dimensions, and the continuous increase of mine ventilation, the original standard design of waterproof gates is far from meeting the needs of mines. At present, the standard design of waterproof gates is only flat. and thin-shell type, of which the flat plate size is 1.7×2.3m, suitable for hydrostatic pressure 1.0-1.6MPa; the thin-shell type has two specifications of 1.7×2.3m and 2.0×2.3m, suitable for hydrostatic pressure 1.6-8.0 MPa. Due to the low hydrostatic...
