The invention discloses a platform synchronization double-cylinder hydraulic system for a shearing hoister. The platform synchronization double-cylinder hydraulic system comprises a first double-cylinder mechanism, a second double-cylinder mechanism and a valve control mechanism. The first double-cylinder mechanism comprises a first hydraulic cylinder and a second hydraulic cylinder. A first air cylinder is arranged at one side of the first hydraulic cylinder, and a second air cylinder is arranged at one side of the second hydraulic cylinder. The second double-cylinder mechanism comprises a third hydraulic cylinder and a fourth hydraulic cylinder. The valve control mechanism comprises an oil route block. The oil route block comprises a first oil port, a second oil port and a third oil port. The first oil port is connected to the first hydraulic cylinder and the third hydraulic cylinder. The second oil port is connected to the first air cylinder and the fourth hydraulic cylinder. The third oil port is connected with the second hydraulic cylinder and the third air cylinder. By means of the platform synchronization double-cylinder hydraulic system for the shearing hoister, the two pairs of double-cylinder hydraulic systems can be arranged in a crossed mode for oil line control, the oil route block is used for controlling oil lines, three ways of output oil ports arranged in the oil route block are used for controlling the hydraulic systems, and thus synchronization balanced lifting of the hoister can be realized.
Description
technical field [0001] The invention belongs to the technical field of scissor lifts, in particular to a synchronous double-cylinder hydraulic system of a scissor lift platform. Background technique [0002] Scissor lifts are auto repair machines used in the auto repair industry. Hydraulic lifts are driven by hydraulic systems, also called hydraulic lifts, which play a vital role in vehicle maintenance. Vehicle overhaul and maintenance are inseparable from hydraulic lifts. With the increase of automobile sales in our country, the demand for lifts, as an important tool for automobile maintenance, has also greatly increased. [0003] During the lifting and lowering process of the multi-cylinder scissor lift, it is extremely important to maintain stability, which requires the synchronous work of the hydraulic cylinders, so it is necessary to provide a hydraulic system to ensure that the hydraulic cylinders of the multi-cylinder scissor lift work synchronously . [0004] In r...
