[0025]SeeFigure 1-5A sealing type double-acting single piston rod hydraulic cylinder, including the cylinder 1, the inner side surface of the cylinder 1, and the inner movable sleeve of the cylinder 1, the internal activity sleeve of the cylinder 1, the outer side of the movable block 11 The equal block 12 is fixedly installed, and the movable block 11 is attached to the limit block 12 and the live portion of the movable block 11, the piston rod 6 is fixedly mounted, and the bottom end of the outer side of the piston rod 6 is equal to the fixed mounting There is a fixed block 16, and both ends of the left and right ends of the fixed block 16 are provided with a support block 21, and the outer side of the support block 21 is in contact with the inner side of the cylinder 1.
[0026]Among them, the outer side of the cylinder 1 is wrapped with a condensed pipe 3, and the outer side surface of the cylinder 1 is fixedly mounted, and a protective case 2 is attached to the outer side of the condenser 3, and the top end of the cylinder 1 is fixedly mounted with a water storage tank 4, a condenser tube 3 The other end of the reservoir 4 is fixed in the internal fixation of the cylinder 1, and the heat generated by the cylinder 1 will be conducted to the outer side of the cylinder 1, and is absorbed by the condensed pipe 3, and heat exchanger with the internal condensed water. Take most of the heat to avoid overheating in the innermost of the cylinder 1.
[0027]The top end of the piston rod 6 penetrates the bottom end of the cylinder 1 and the piston plate 7 is fixedly mounted. The central fixed communication in the top end of the cylinder 1 can be injected into the hydraulic oil to promote the activity block 11 by implantation of the oil pressure. Displacement between the cylinder 1.
[0028]Among them, the bottom end of the cylinder 1 is provided in a cleaning ring 13 on the left and right sides of the piston rod, and the shape of the two cleaning ring 13 is a semi-circular shape, and the two ends and lower ends of the two cleaning ring 13 have a mounting groove 14, When the two cleaning ring 13 adsorbs the magnet 15 by the mounting groove 14, when the piston rod 6 is recovered, since the surface of the piston rod 6 is in the inner side surface of the cleaning ring 13, the piston rod 6 is treated during the displacement After the dust is cleaned, the detachment of the two cleaning ring 13 can be cleaned by disassembling the magnet 15.
[0029]Wherein, one end of the limiting block 12 is fixedly mounted having a second buffer spring 10 in the limit slot 8, and the bottom end of the second buffer spring 10 is fixed to the bottom end of the limit slot 8, the bottom end of the movable block 11. Fixed installed in the cylinder 1 internal first buffered spring 9, the bottom end of the first buffer spring 9 is fixed to the bottom end of the cylinder 1 inner cavity, and the bottom end of the movable block 11 is fixedly installed with a buffer pad 24, when the piston rod 6 When recovered, the first buffer spring 9 located at the bottom of the movable block 11 and the second buffer spring 10 in the limit slot 8 are compressed to buffer the recovery of the piston rod 6, and the cushion 24 can continue to absorb the impact force. The buffer is further buffered and the service life is increased.
[0030]Among them, the internal activity of the chute 17 is attached to the slider 18, and one end of the slider 18 is fixedly mounted, and the lower movable frame 20 is provided above the upper movable frame 19, the upper movable frame 19, and the lower movable frame 20 There is a rotating shaft 23, and the upper movable frame 19 and the lower movable frame 20 are rotated by the shaft 23, and the upper movable frame 19 and the lower movable frame 20 can be relatively rotated, and the slider 18 can be driven when the movable frame 20 is rotated on the upper movable frame 19. The relative chute 17 is displaced.
[0031]Wherein, the top end of the upper movable frame 19 is fixed to the bottom end of the support block 21, and the bottom end of the upper movable frame 19 is fixedly mounted, and the bottom end of the support spring 22 is fixed to the top end of the fixed block 16, when the piston rod 6 The support block 21 subjected to the side impact force at the fixed block 16 is then pressure, at which time the support spring 22 at the bottom end of the support block 21 is subjected to pressure and correspondingly compressed, drive the movable frame 19 downward, at this time at this time 23 The drive can drive the movable frame 19 to rotate the moving frame 20 to the lower movable frame 20 to drive the slider 17 displacement to cancel the partial impact force, slow down the impact force of the piston rod 6.
[0032]Working principle, the sealing type double active single piston rod hydraulic cylinder can be implanted by injection of the hydraulic oil by the injection port 5, and the displacement of the active block 11 is displaced between the movable block 11 and the displacement of the piston rod 6 can be pushed. The heat generated when the cylinder 1 is operated, and the heat pipe 3 is absorbed by the condensed tube 3, and the internal condensed water is heat-conducting and takes away most of the heat, avoiding the cylinder 1 Internal superheated phenomenon, when the piston rod 6 is located above the side towers, the support block 21 is immediately affected, at which time the support spring 22 at the bottom end of the support block 21 is subjected to pressure and correspondingly compressed, driving the movable frame 19. Move down, at this time, the movable frame 19 can be moved to the moving frame 19 to rotate the movable frame 19 against the lower movable frame 20 to drive the slider 18 relative to the slider 17 to offset the partial impact force, slow down the impact of the piston rod 6, When the piston rod 6 is recovered, since the surface of the piston rod 6 is in the inner side surface of the cleaning ring 13, the dust is cleaned by the friction during the displacement process, by disassembling the magnet 15, two The removal of the cleaning ring 13 is cleaned, and the first buffered spring 9 located at the bottom of the movable block 11 and the second buffered spring 10 located inside the limit slot 8 are compressed to buffer the recovery of the piston rod 6 while buffering. The pad 24 can also continue to absorb the impact force to further buffer it, increasing the service life.
