Embodiment Construction

[0024] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0025] One, structural form of the present invention.

[0026] The arc arched split waterproof gate is composed of two split arc arched door leaves and a separable door frame, see Figures 1, 2, 3 and Figures 4, 5, and 6 for details.

[0027] 1. Double-open arc arched door leaf (see Figure 1, 2, 3 for details)

[0028] The split arc arched door leaf consists of a left door leaf 5, a right door leaf 6, and four hinge connecting plates 1.12

[0029] (respectively 2 left and right door leaves), eight suspension rings 1.13 (4 for each door leaf), two front supports 1.14 (1 for each door leaf) of opening and closing hydraulic jacks. The left and right door leaves are arranged symmetrically, with the same structure and size, consisting of arc-shaped door panels 1.1, center door eaves 1.2, arc-shaped transverse ribs 1.3, vertical straight ribs 1.4, left ...

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 split type 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 split type 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; and the door leaves are arranged on the door frame by a door pivot. The circular arched split type waterproof strobe is characterized in that the upper door frame and the lower door frame have the circular arched shape; the cross section of the door leaves has the circular arched shape; the radians of the door leaves are consistent with the radians of the upper door frame and the lower door frame; and each of the door leaves consists of a left door leaf and a right door leaf which are symmetrical. The circular arched split type waterproof strobe has the following advantages of wide application range, large bearing capacity and large door area which can meet the use requirement of 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 arched split waterproof gate in underground mines. Background technique [0002] Setting waterproof gates in mine underground roadways is a waterproof measure that is generally adopted 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 existing standard design of waterproof gates can no longer meet the needs of mines. At present, the standard design of waterproof gates is only flat and There are two types of thin-shell type, of which the flat type is 1.7×2.3m, applicable to hydrostatic pressure 1.0-1.6MPa; thin-shell type is 1.7×2.3m and 2.0×2.3m, applicable to hydrostatic pressure 1.6-8.0MPa . The flat-plate waterproof gate is rarely used in underground mines due to its low hydrost...
