The working principle is as follows: the hydraulic tension oil cylinder is started to work through the control panel 5, at the moment, the oil cylinder body 2 drives the limiting plate 3 to move, then the limiting plate 3 moves to drive the rack 4 to move, the rack 4 moves to drive the first gear 8 to rotate, under the matching of the first rotating rod 6 and the one-way bearing 7, the first gear 8 drives the second gear 10 to rotate on the second rotating rod 9, further the coil 12 is driven to cut a magnetic induction line between the two magnets 11, then current is generated, the generated current is transmitted to the electromagnetic valve 16 through the commutator 13, the electromagnetic valve 16 is started to flow lubricating oil in the oil tank 15, the lubricating oil sequentially passes through the connecting pipe 14 and the liquid outlet pipe 17, finally the spraying head 18 is reached to lubricate the oil cylinder in time, great damage caused by abrasion of parts in the oil cylinder is reduced, meanwhile, when the rack 4 moves, the helical teeth on one side of the rack 4 drive the bevel gear 21 to rotate, then the bevel gear 21 drives the T-shaped block 20 to rotate, then the T-shaped block 20 drives the first magnet 22 to rotate in the groove 19, when the first magnet 22 reaches the bottommost end, the first magnet is matched with the second magnet 26, according to the principle that like poles of the magnets repel each other and opposite poles of the magnets attract each other, the second magnet 26 pushes the second magnet 26, the second magnet 26 drives the sliding block 25 to move, the second expansion spring 24 is stretched, the gas in the extrusion gas box 23 is matched with the second one-way valve 28, the gas circulation gas outlet pipe 29 blows the lubricating oil sprayed by the gas outlet 30 to the oil cylinder, the sprayed lubricating oil uniformly and quickly enters the oil cylinder for lubrication, when the first magnet 22 reaches the topmost end, under the matching of the second magnet 26 and the second expansion spring 24, the sliding block 25 moves upwards to be matched with the first one-way valve 27, and the external gas enters the gas box 23 through the first one-way valve 27, supplement the inside gas of gas tank 23 with this reciprocal, when the hydro-cylinder finishes work and begins to shrink, according to the cooperation of one-way bearing 7, shower nozzle 18 can not work, and gas outlet 30 is bloied under the cooperation of conical gear 21, first check valve 27 and second check valve 28, blow off the dust on the hydro-cylinder, rack 4 moves down simultaneously drives slide 33 downstream through connecting block 34 and promotes the inside air current of box 31, under the cooperation with air outlet valve 35, and then moves the inside dust of casing 1 through play hopper 37 and blast pipe 36, finally reach the inside collection box 38 and collect, the gathering of dust has effectively been reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
