Technical Field
The utility model relates to the technical field of protection of piston rods, in particular to a protection device of a piston rod.
Background
Hydraulic cylinders are a common type of hydraulic actuator used to convert hydraulic energy into mechanical energy. It generally consists of a cylinder and a piston movable therein. The cylinder is filled with a liquid (typically hydraulic oil) and when the liquid enters the cylinder from an inlet, the pressure pushes the piston into the cylinder. The piston rod is a part of the hydraulic cylinder connected with the outside, is of a rod-shaped structure, and when hydraulic pressure acts on the piston in the hydraulic cylinder, the piston rod receives thrust and transmits the thrust to other mechanical devices to realize movement or force application.
Because the cylinder moves, the piston rod that stretches out outside the cylinder can expose the external world, therefore when the operation under high dust environment, the dust can adhere on the surface of piston rod, and can mix in fluid, and over time, the impurity of fluid is more and more, and the fluid that just has the impurity at this moment is equivalent to the abrasive, carries out the continuous grinding to the sealing member in the system during operation, will cause the harm to the sealing member of other spare parts in the hydraulic system and the sealing member of pneumatic cylinder itself.
In order to avoid dust adhesion on the surface of the piston rod, workers often install telescopic jackets additionally on edges, close to the end heads, of the cylinder barrel and the piston rod of the hydraulic cylinder, and the telescopic jackets can effectively prevent the dust from contacting with the piston rod. The two ends of the telescopic sheath are circular sleeves which are respectively sleeved on the outer wall of the circular cylinder barrel and the edge of the piston rod close to the end head and locked by the steel belt anchor ear. However, the shape of the hydraulic cylinder is square when seen from the outside, and when the round sleeve of the telescopic sheath is sleeved outside the square cylinder barrel, the hydraulic cylinder is difficult to be tightly stuck to the periphery of the square cylinder barrel by using the steel belt anchor ear, so that the tightness between the telescopic sheath and the square cylinder barrel is influenced, and the protection of the piston rod is influenced. For this purpose we propose a protection device for the piston rod.
