Description
Technical Field
The utility model belongs to the technical field of the hydraulic cylinder technique and specifically relates to an inverted hanging type hydraulic cylinder's piston rod assembly.
Background
At present, many hydraulic engineering are city landscape engineering, and for the integral attractiveness, for example, hydraulic opening and closing machines in the form of flat gates do not allow oil cylinders to be exposed outside. This requires that the cylinder position be placed very low, but often the design construction height, environment etc. of site are not allowed.
In order to solve the problem that an oil cylinder is exposed, a cylinder body of the oil cylinder is installed into a gate, a piston rod is fixed, and the cylinder body of the oil cylinder drives the gate to move. The traditional oil cylinder has the advantages that the cylinder body is fixed, and the piston rod moves, so that an oil pipe can be directly connected with a rodless cavity and a rod cavity of the oil cylinder; however, if the upside-down type oil cylinder is used, the cylinder body of the oil cylinder can only be connected by a hose, but the long hose can influence the appearance and the service life, and is not safe. Therefore, a piston rod assembly for a reverse hanging type oil cylinder is designed, and oil pipes of a rodless cavity and a rod cavity are connected to a fixed piston rod.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the problems existing in the background technology, an improved piston rod assembly of an inverted hydraulic oil cylinder is provided.
The utility model provides a technical scheme that its technical problem adopted is: a piston rod assembly for an inverted oil cylinder comprises a piston rod head, a piston rod body, a piston rod tail, a high-pressure oil pipe and a piston;
the piston rod body is of a hollow structure, the high-pressure oil pipe is arranged in the piston rod body, the piston rod head and the piston rod tail form an integral structure with the piston rod body through welding to ensure that the piston rod is sealed and oil-tight, and the piston is arranged on the piston rod tail;
the piston rod head and the piston rod tail are respectively provided with a rod cavity channel interface and a rodless cavity channel interface, the rodless cavity channel interfaces on the piston rod head and the piston rod tail are respectively welded with the high-pressure oil pipe, and the drift diameter of the high-pressure oil pipe is determined according to the flow determined by the running speed of the oil cylinder.
Furthermore, the piston rod head and the rod cavity channel interface at the tail of the piston rod are communicated with each other;
furthermore, an O-shaped sealing ring is arranged between the piston rod tail and the piston;
through adopting above-mentioned technical scheme for the sealed of piston rod tail and piston prevents internal leakage.
Further, the piston is connected on the piston rod tail through a locking nut in a locking mode.
Through adopting above-mentioned technical scheme, the piston can not follow and slips from the piston rod.
The utility model has the advantages that: the utility model provides a problem that exists among the background art, designed a piston rod assembly that can be used to the formula of hanging upside down hydro-cylinder, the oil pipe that no pole chamber and have the pole chamber connects on the piston rod of immobility for the formula of hanging upside down hydro-cylinder can reach easy to assemble oil pipe, can guarantee the security and the reliability of whole hydro-cylinder operation again.
