Abstract

The invention discloses a hydraulic oil cylinder piston rod adjusting device. The hydraulic oil cylinder piston rod adjusting device comprises a fixing seat, an adjusting plate, a guide rail, a supporting seat and an adjusting assembly, wherein an adjusting groove is formed in the fixing seat, the adjusting plate is arranged on the adjusting groove, the guide rail is arranged on the adjusting plate, the supporting seat is in sliding connection with the guide rail, the supporting seat can move in the extending direction of the guide rail, and the supporting seat is used for being connected witha piston rod; the adjusting assembly is movably connected with the fixing seat and the adjusting plate respectively, the adjusting assembly adjusts the position of the adjusting plate in the adjusting groove, so that the contact surface of the supporting seat and the piston rod is in a horizontal position, and the supporting seat fixes the piston rod and enables the piston rod to be in a horizontal position. According to the hydraulic oil cylinder piston rod adjusting device, and the piston rod of the hydraulic cylinder can be always in the horizontal position, and the oil leakage of the hydraulic cylinder caused by the unilateral abrasion of a sealing part due to the fact that the piston rod is drooping due to self-weight is avoided.

Description

technical field [0001] The invention relates to a hydraulic transmission technology, in particular to a hydraulic oil cylinder piston rod adjustment device. Background technique [0002] In the hydraulic cylinder transmission technology, when the cylinder is placed horizontally, if one end of the piston rod is suspended in the air, the piston rod will sag due to its own weight, causing unilateral wear of the seal and guide elements, resulting in oil leakage from the hydraulic cylinder. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a hydraulic cylinder piston rod adjustment device, which can keep the hydraulic cylinder piston rod in a horizontal position all the time, avoiding the hydraulic pressure caused by the unilateral wear of the seal caused by the piston rod drooping due to its own weight. The cylinder is leaking oil. [0004] The purpose of the present invention adopts fo...
