The invention discloses a quick-tensioning energy-saving rotary hydraulic device, which comprises a connecting seat, a connecting rod, a valve seat, a first hydraulic lock, a second hydraulic lock, afirst oil cylinder, a second oil cylinder and a shuttle valve. The connecting seat is fixedly connected with the connecting rod, the valve seat is rotatably connected with the connecting rod, the shuttle valve is mounted on the connecting seat, the first hydraulic lock and the second hydraulic lock are arranged on the valve seat, and a first oil passage and a second oil passage which can be switched are arranged in the valve seat, the connecting rod and the connecting seat. The shuttle valve is sequentially connected with the first oil passage and the first hydraulic lock; the first hydrauliclock is connected with the first oil cylinder and the second oil cylinder; an oil inlet pipeline is connected with the second hydraulic lock through the second oil channel; and the second hydraulic lock is connected with the first oil cylinder and the second oil cylinder. The quick-tensioning energy-saving rotary hydraulic device has the beneficial effects that the hydraulic oil way has the functions of oil way switching, oil liquid energy saving, oil cylinder quick tensioning and oil cylinder pressure maintaining, the design is reasonable, use is convenient, and therefore the working efficiency and practicability of forklift accessories are improved.
Description
technical field [0001] The invention relates to a hydraulic device, in particular to a fast-opening and energy-saving rotary hydraulic device. Background technique [0002] With the rapid development of the domestic handling industry, the market for forklift attachments is also growing. The application of fast-opening and energy-saving rotary hydraulic devices in forklift attachments will greatly improve the operating efficiency of forklift attachments. The existing hydraulic oil circuit of forklift attachments still has the following problems. The oil circuit is connected with a high-pressure rubber hose and the switching of the oil circuit is cumbersome. The opening speed of the oil cylinder is slow, resulting in low work efficiency. Pressure cannot be maintained in the vertical position, so it is particularly important to provide a fast-opening energy-saving rotary hydraulic device design. [0003] The information disclosed in this Background section is only for enhancin...
