Problems solved by technology
[0002] At present, forklifts equipped with flat clamps, side shifters and other attachments are very common among special customer groups. The handling efficiency is high and the cost of manual handling is reduced. Attachment products such as clips and side shifters can only be used in the low-end market, and high-end customers urgently need high-performance forklift attachments to meet their use requirements

Embodiment Construction
[0014] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0015] Such as figure 1 and figure 2 As shown, a synchronous control hydraulic system includes a diverter and flow valve 101, a first buffer valve 102, a second buffer valve 103, a first hydraulic control check valve 104, a second hydraulic control check valve 105, and a third hydraulic control valve. Control the check valve 106, the shuttle valve 107, the first actuator 201 and the second actuator 202. The above hydraulic valves are installed on the oil circuit board, and the oil circuit board is equipped with CLAMP oil port, OPEN oil port, SSR or The SSL oil port, the second hydraulic control check valve 105 and the third hydraulic control check valve 106 are controll...

The invention provides a synchronous control hydraulic system which integrates the function that the loosening action is faster than the clamping action, the function that the loosening action and the clamping action are synchronous, the function of pressure maintaining of executive components and the function of lateral movement. The synchronous control hydraulic system comprises a flow distributing and collecting valve, a first trimmer valve, a second trimmer valve, a first hydraulic control one-way valve, a second hydraulic control one-way valve, a third hydraulic control one-way valve, a shuttle valve, the first executive component and the second executive component, wherein all the hydraulic valves are installed on an oil-way plate, the oil-way plate is connected with the first executive component and the second executive component, so that the situation that the loosening action of the first executive component and the second executive component is faster than the clamping action and the situation of synchronous loosening and clamping actions are achieved; meanwhile, goods do not fall off and a CLAMP oil way and an OPEN oil way are disconnected after the CLAMP oil way and the OPEN oil way are cut off, and an SSR oil mouth or an SSL oil mouth supplies oil so as to achieve rightward movement or leftward movement.
Description
technical field [0001] The invention relates to a synchronous control hydraulic system. Background technique [0002] At present, forklifts equipped with flat clamps, side shifters and other attachments are very common among special customer groups. The handling efficiency is high and the cost of manual handling is reduced. Attachment products such as clips and side shifters can only be used in the low-end market, and high-end customers urgently need high-performance forklift attachments to meet their use requirements. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic system that simultaneously integrates the opening action speed faster than the clamping action function, the opening and clamping action synchronization function, the actuator pressure maintaining function, and the side shifting function. [0004] In order to solve the above problems, the present invention is achieved through the following technical solutions: ...
