Description
Technical Field
The utility model relates to a hydraulic equipment technical field specifically is a pneumatic cylinder convenient to change piston seal spare.
Background
The rotating tower is an amusement apparatus with the theme of rotation and lifting. The shuttle body cabin ascends, descends and continuously moves up and down along the vertical tower rail, so that passengers experience thrill and stimulation in the rotating and ascending processes.
The rotating tower takes a main hydraulic cylinder as a power source, when a piston rod of the hydraulic cylinder retracts into a cylinder barrel, the piston rod pulls a steel wire rope to drive a shuttle body to move upwards, the shuttle body decelerates and stops after reaching a peak, then the shuttle body slides downwards quickly along a tower frame by means of potential energy generated by the weight of the shuttle body and a human body, and meanwhile the tower frame drives the shuttle body to rotate freely.
The original hydraulic cylinder has problems: when the shuttle body cabin descends rapidly from the highest position of the tower to the maximum running height of the shuttle body cabin, the speed is high. Although the speed is reduced by the movable pulley block, the speed of the piston rod of the hydraulic cylinder still reaches 2m/s. The oil temperature of the hydraulic cylinder also changes dramatically due to the change of the external load. As the equipment runs longer, wear and degradation of the seals between the piston and the cylinder occurs where the seals fail. Then a large amount of oil leaks at the oil leakage recovery port of the lower joint of the cylinder barrel, a rod cavity of the hydraulic cylinder cannot keep constant pressure, the lifting speed of the shuttle body cabin fluctuates greatly, and the equipment cannot work normally. The normal operation of the device can only be restored by replacing the seal at the piston. The hydraulic cylinder is vertically arranged inside an outdoor tower frame and is nearly ten meters long, a lower connector of the cylinder barrel is hinged to a rotating seat at the bottom of the tower frame through a pin shaft, and an upper connector of the rod end of the hydraulic cylinder is connected with the movable pulley assembly through a pin shaft. The whole hydraulic cylinder cannot be hung out of the tower or the piston rod of the hydraulic cylinder cannot be pulled out of the cylinder barrel, so that the sealing element at the piston cannot be replaced or the replacement cost is too high. Based on the improvement of the local structure of the original hydraulic cylinder, the hydraulic cylinder for the rotating tower is newly designed, and the piston sealing element is convenient to replace.
