DW single hydraulic prop adopts the principle of plunger suspension technology, so that the hydraulic suspension force directly ACTS on the roof through the internal cavity of the single hydraulic prop living column. It improves the stability and safety of the pillar, as well as the support height and bearing capacity of the prop. At the same time, it also guarantees the safety of underground workers. So let's see how it works.
Operation sequence of DW single hydraulic prop:
Hanging beam → insert and adjust the Angle wedge → back top → clean and position the column → stand the column → feed the liquid to lift the column (the working face using the top net should first hang the net and then operate in its sequence).
(1) hanging beam. One person stands where the bracket is complete and grabs the hinged roof beam with both hands and inserts it into the ears of the installed roof beam. The other person stands on the sidewalk, inserts the roof beam round pin and hits the round pin in place with a hammer.
(2) insert Angle wedge. Hold up the top beam and insert the Angle adjusting wedge from bottom to top, leaving a gap of 0.1 ~ 0.15m between the beam and the roof.
(3) back to top. Cross back with the top material of the shelf according to the specified quantity and tighten the horizontal wedge with hammer.
(4) cleaning and positioning of columns. Determine the column position according to the provisions of the operation rules, clean the column position float coal, chisel the column hole or hemp surface, need to wear shoes, shoes flat on the column position.
(5) vertical column and lifting column. Catch a prop of the hand above the slope, a man put to put on the column a prop, the other people take note liquid gun stand at the bottom of the pillar, turn the pillar make liquid injection valve down, and then rinse fluid injection pulverized coal in the valve, the liquid gun card deck tight injection liquid injection valve, open to promote feed liquid on the, the column beam tooth and claw stuck for liquid reaches the early supporting force, back bets liquid and hung on the prop hand gun, and got behind the prop and beam.
DW single hydraulic prop can still meet the larger constant increasing drag drop distance, easy to return column, improve the recovery of the prop, reduce the consumption of the prop and production costs.
