Embodiment Construction
[0011] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown in the figure, an all-round walking advance hydraulic support is mainly used for the advance support of the return air tunnel of the working face, including the hydraulic support top beam (1), column (2), stable support (3), base (4) , lifting jack (5), fixed frame (6), screw drum (7), power unit (8) and other components. The spiral drum (7) is arranged on both sides of the base (4). When the advanced hydraulic support needs to move, the column (2) shrinks, the top beam (1) leaves the roof of the roadway, the lifting jack (5) moves, and the fixing frame (6) Rotating downwards, the helical drum (7) touches the bottom plate.
[0013] A pair of right-handed helical rollers (7) rotate clockwise synchronously under the action of the power unit (8), and the leading bracket moves parallel to the left; the helical rollers (7) r...
