Anti-decompression connector hydraulic system of vehicle carrier vehicle

Abstract

The invention discloses an anti-decompression connector hydraulic system of a vehicle carrier vehicle. The anti-decompression connector hydraulic system comprises an anti-decompression connector. The anti-decompression connector comprises a connector body, a current-limiting piece, an adjusting screw, a spring and an anti-dropping nut. One side of the connector body is provided with an A-end connector, the A-end connector is connected with an oil pipe of the vehicle carrier vehicle, the other side of the connector body is provided with a B-end connector, the B-end connector is connected with an oil cylinder of the vehicle carrier vehicle, the middle position of the connector body is provided with a plurality of overflow ports, one side, close to the B-end connector, of the inside of the connector body, is further provided with a clamping groove, and the clamping groove is horizontally disposed at the middle position of the overflow port and communicated with the B-end connector. One end of the spring is fixedly connected with the inner wall of the clamping groove, the other end of the spring is connected with the current-limiting piece, and the spring sleeves the adjusting screw. The anti-decompression connector hydraulic system is reasonable in design, simple in structure and easy to implement, responds sensitively and is high in reliability, and a safety factor of the hydraulic system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicle transport vehicles, in particular to a hydraulic system for anti-pressure loss joints of the vehicle transport vehicle. Background technique [0002] The current vehicle transporter lifting platform is multi-purpose hydraulic cylinder, hydraulic cylinder plus wire rope pulley block, hydraulic cylinder plus chain pulley block and other structures. In the process of use, due to the poor pressure-holding performance of the simple hydraulic cylinder, there is self-dropping, poor self-locking performance, and poor reliability. If the oil return pipe of the hydraulic cylinder bursts accidentally or the hydraulic system fails, the lifting platform will quickly fall due to gravity, which will easily cause a safety accident. In order to prevent such accidents, the structure of hydraulic cylinder plus hydraulic lock (two-way hydraulic control check valve) is basically adopted. This structure is relatively ...

AI Technical Summary

Problems solved by technology

In the process of use, due to the poor pressure-holding performance of the simple hydraulic cylinder, there is self-dropping, poor self-locking performance, and poor reliability.

If the oil return pipe of the hydraulic cylinder bursts accidentally or the hydraulic system fails, the lifting platform will quickly fall due to gravity, which will easily cause a safety accident

In order to prevent such accidents, the structure of hydraulic cylinder plus hydraulic lock (two-way hydraulic control check valve) is basically adopted. This structure is relatively complicated, takes up a large space, and costs high. In addition, the reliability of the hydraulic lock needs to be further improved. Therefore, We propose a vehicle transporter anti-loss joint hydraulic system to solve the above problems
