Abstract

The invention discloses a double-oil-cylinder series-parallel connection oil way switching device which comprises a first stop valve, a second stop valve, a third stop valve, an operating handle and aplurality of pipeline connecting pieces. The double-oil-cylinder series-parallel connection oil way switching device is provided with an oil inlet, an oil return port and a plurality of working oil ports for being connected with a left side oil cylinder and a right side oil cylinder respectively. The first stop valve, the second stop valve and the third stop valve are connected or disconnected under the control of the operating handle so as to realize the switching between series connection and parallel connection of the left side oil cylinder and the right side oil cylinder. The double-oil-cylinder series-parallel connection oil way switching device is simple in structure and convenient to operate, and is installed in a hydraulic system formed by combining two hydraulic oil cylinders, and the series connection state and the parallel connection state of double-oil-cylinder oil ways can be rapidly switched so as to meet different use working conditions of a double-oil-cylinder set; andthe double-oil-cylinder series-parallel connection oil way switching device is low in cost, free of oil leakage, safe, reliable and suitable for popularization.

Description

technical field [0001] The invention relates to an oil circuit switching device, in particular to a double oil cylinder series-parallel oil circuit switching device. Background technique [0002] In a tank transport vehicle, two hydraulic oil cylinders drive a tank attitude adjustment device to adjust the attitude of the tank in the horizontal direction. During normal operation, the oil circuits of the two hydraulic cylinders are connected in series to ensure the synchronous movement of the two cylinders. After using for a certain period of time, the internal leakage of the oil cylinder or the external leakage of the oil circuit will cause a synchronization error between the two oil cylinders, and as time goes on, the error will become larger and larger. In order to eliminate the synchronization error, after the system has been running for a period of time, it is necessary to adjust the oil circuits of the two hydraulic cylinders to a parallel state and correct the two hydr...
