The specific embodiment
The below will be described in further detail the embodiment of the invention.
Large inclination working surface support rigidity Adjustable device cash device of the present invention, its better specific embodiment is:
Back timber at the large inclination working surface support is provided with following any one or more waste rock board: waste rock board between waste rock board, machine road waste rock board, frame before the frame;
Described front waste rock board is hinged on the back timber before the column, is provided with first between described front waste rock board and the back timber and stretches the receipts jack;
Described machine road waste rock board is hinged on the back timber of top, machine road perpendicular to the machine road, be provided with second between described machine road waste rock board and the back timber and stretch the receipts jack, described machine road waste rock board comprises one-level waste rock board and the secondary waste rock board that connects by slideway, is provided with one or two flexible jack between described one-level waste rock board and the secondary waste rock board;
Waste rock board is installed on the slide rail that arranges along the back timber length direction of top, walkway in the frame between described, be provided with jack for moving between waste rock board and the back timber between described, waste rock board comprises one-level waste rock board and the secondary waste rock board that connects by slideway between described, is provided with one or two flexible jack between described one-level waste rock board and the secondary waste rock board.
Large inclination working surface support rigidity Adjustable device cash device of the present invention is divided into three parts: the one, and rigidity can be stretched the receipts waste rock board before the frame, and the 2nd, the scalable receipts waste rock board of stretching in machine road, the 3rd, scalable removable waste rock board between frame.With machine road waste rock board, extended during use, the time spent is not recoverable before the frame; Waste rock board can use height according to support between machine road, frame, regulates the length of waste rock board; Waste rock board is removable between frame, so that the pedestrian passes through.Three parts can be installed on the same support as required in any combination way.
The design feature difference of three parts:
1, waste rock board before the frame:
Be fixed on the front back timber of column, stretch receipts by stretching the control of receipts jack, waste rock board is positioned at the top of the rear front scrapping plate electric cable groove of trying to stop people from fighting each other before the frame when the operating position, does not namely affect the walking of coal-winning machine, does not affect again the front walkway of frame.Waste rock board adopts the jack stroke limit when the operating position before the frame, prevents from impacting when excessive, and waste rock board turns back and jeopardizes pedestrains safety.
2, machine road waste rock board:
1) machine road waste rock board is to be made of one-level, secondary waste rock board and two flexible jack that two Plate Weldings inlaying with slideway form, and under the control of flexible jack, the secondary waste rock board can stretch.2) machine road waste rock board is installed on the set cap of top, machine road, be installed in the upper direction side of support perpendicular to the machine road, by stretching the receipts of stretching of receiving jack controller road waste rock board, during off working state, machine road waste rock board is recovered to the position of being close to the back timber web, does not affect the normal operation of coal-winning machine and scrapper conveyor.
3, waste rock board between frame:
1) waste rock board is to be made of one-level, secondary waste rock board, guide peg and flexible jack that two Plate Weldings inlaying with slideway form between frame, and under the control of flexible jack, the secondary waste rock board can stretch.2) waste rock board is installed on the set cap of top, walkway in the frame between frame, is installed in the upper direction side of support perpendicular to walkway in the frame, by moving forward and backward along the stent length direction of waste rock board between jack for moving control frame.When the pedestrian by between frame during the waste rock board position, waste rock board slippage open walk between jack for moving control frame passes through the pedestrian smoothly.Jack for moving adopts all controllable hydraulic plumbing systems of this and adjacent frame.
The above; only for the better specific embodiment of the present invention, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
