Single hydraulic prop hanging beam, pull it in the complete position of the support, fix the hinged top beam with both hands, insert the hydraulic prop into the ears of the placed top beam, use electrophoretic paint, in the water-soluble paint can, use the workpiece For the cathode, apply a certain voltage and time to form a uniform thickness of paint on all surfaces of the spring, and then clean and dry
The appearance of the hydraulic acrow props is clean and dull, no particles, no exposure, the binding force is not easy to fall off, the hardness is 3-4H, and various instruments of the equipment should be checked regularly.
The maintenance card should be established for the maintenance of hydraulic acrow props to record in detail the prop number, service content, service date, error calculations, test conditions, etc. Mixed use of floating plunger type and fixed piston type, even if the bearing capacity distribution is reasonable, it also solves the advanced problem of large-stroke pillar liquid injection.
The single hydraulic prop is filled with liquid on the outer guide sleeve of the first-stage working cylinder, and there is no circumferential welding on the movable post that cannot be guaranteed by the process, which avoids the danger of welding leakage and damage to the effective accident of the prop sealing performance. Another person stands on the sidewalk, inserts the top beam round pin and uses a hammer to hit the round pin in place.
Insert the angle wedge. Lift the ceiling beam and insert the adjusting angle wedge from bottom to top, leaving a gap of 0.1-0.15 meters between the beam and the ceiling. The top of the back is crossed with the material of the back of the upper frame to raise the back, and the horizontal wedge is tightened with a hammer.
Clean the fixed single hydraulic prop position. Determine the position of the column according to the operating regulations, clean the floating charcoal of the column, excavate the column socket and pitted surface, if you need to wear shoes, put the shoes on the column.
Column and rising column. One person B grabs the handle of the support and stands on the pillar. The other person holds the injection gun under the pillar. The single hydraulic prop rotates the support so that the injection valve faces downwards, flushing out the medium in the words. Put the injection gun into the injection valve, move the handle and lift up the body supply so that the column claws are stuck to the beam teeth and the liquid supply reaches the prescribed setting force, and the injection gun is retracted and hung on the handle of the pillar. The pillar and the beam are united into a body.
Insert the angle wedge. Lift the ceiling beam and insert the adjusting angle wedge from bottom to top, leaving a gap of 0.1-0.15 meters between the beam and the ceiling.
The top of the back is crossed with the material of the back of the upper frame to raise the back, and the horizontal wedge is tightened with a hammer.
