Abstract

A buffer device of a hydraulic oil cylinder is provided with the hydraulic oil cylinder (1), a connecting block (7), a solenoid valve (3) and an energy accumulator (6). A first end of the connecting block (7) is connected with the hydraulic oil cylinder (1), a second end of the connecting block (7) is connected with the energy accumulator (6), the connecting block (7) is provided with a through hole (70) enabling a rodless cavity of the hydraulic oil cylinder and the energy accumulator to be communicated, and the solenoid valve is used for achieving non-communication and communication of the through hole (70). When the through hole of the connecting block is communicated, the hydraulic oil cylinder has the buffer effect. When the through hole is not communicated, the hydraulic oil cylinder is located in a rigidity state.

Description

technical field

[0001] The invention relates to the technical field of hydraulic cylinders, in particular to a buffer device for hydraulic cylinders. Background technique

[0002] In some large-scale construction machinery, such as the scraper bucket of the active scraper, it depends on the hydraulic cylinder to raise and lower. The transport bucket is maintained at a certain station. During the movement, due to the unevenness of the ground, the acceleration and deceleration actions and the vibration from the equipment itself, the equipment will vibrate, which will generate a large impact on the hydraulic cylinder in a rigid state, which will improve the comfort of the operator. Sexuality, reducing the maintenance cycle and maintenance costs of equipment will bring adverse effects. Contents of the invention

[0003] In order to overcome the defects of the prior art, the present invention provides a buffer device for the hydraulic cylinder, which can maintain the hydrauli...
