Gas buffering yawing-force-resistant hydraulic cylinder and yawing-force-resistant method thereof

Abstract

The invention relates to the technical field of hydraulic cylinders, in particular to a gas buffering yawing-force-resistant hydraulic cylinder and a yawing-force-resistant method thereof. The gas buffering yawing-force-resistant hydraulic cylinder is simple in structure and scientific in design, and yawing force is resisted through a supporting cylinder fixedly connected with a piston rod, gas buffering is realized through a front buffering cavity, a rear buffering cavity and dampers, and the dangerous situations that when a working part at a high movement speed is driven by the hydraulic cylinder, a structural element is damaged and oil leakage is caused are reduced. The gas buffering yawing-force-resistant hydraulic cylinder comprises an inner cylinder body and an outer cylinder body. The front ends and the rear ends of the inner cylinder body and the outer cylinder body are provided with a front end cover and a rear end cover correspondingly. The supporting cylinder is arranged ina cavity between the inner cylinder body and the outer cylinder body. The rear end of the supporting cylinder divides the cavity into the front buffering cavity and the rear buffering cavity. The front end of the supporting cylinder penetrates through the front end cover and extends out of the front end cover. A piston rod is arranged in an inner cavity of the inner cylinder body. The rod end of the piston rod penetrates through the front end cover and the front end of the supporting cylinder to be fixedly connected with the supporting cylinder. The front end cover and the rear end cover are provided with a first oil hole, a second oil hole and the dampers correspondingly.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a gas buffer anti-lateral force hydraulic cylinder and an anti-lateral force method thereof. Background technique [0002] With the rapid development of domestic construction machinery, the hydraulic cylinder industry has also made great progress, and the market's various performance requirements for hydraulic cylinders have become more and more stringent. Its quality directly affects the performance and quality of the whole machine. It is related to the working reliability of the whole machine and its market competitiveness. The lateral force resistance and buffering capacity are also two important indicators to measure the performance of hydraulic cylinders. [0003] For hydraulic cylinders, under normal circumstances, lateral force will be generated. In severe cases, it will cause oil leakage, damage to structural parts and other hazards, which may cause the host s...

Problems solved by technology

[0003] For hydraulic cylinders, under normal circumstances, lateral force will be generated. In severe cases, it will cause oil leakage, damage to structural parts and other hazards, which may cause the host system to fail to work normally; In order to eliminate the mechanical impact between the piston and the cylinder head caused by the inertia force of the moving parts and the hydraulic pressure, a buffer device will be installed on the hydraulic cylinder
