Problems solved by technology
[0002] In the development of modern industrial technology, the development of hydraulic control systems has been very mature. In various production workshops, we can often see some large-scale, high-power hydraulic systems. These hydraulic control systems are often mechanized and pipelined. , the process and return of these hydraulic control systems reach the maximum displacement to obtain the maximum output power to adapt to some large-volume production, but in some small-scale production and some production activities with strong manual operation, this large-scale high-power The advanced hydraulic control system seems to be overqualified, and it cannot meet the effect of manual fine-tuning, and the control of some detailed operations is poor.

The invention discloses a manual feeding and returning two-way hydraulic system, which comprises a hydraulic cavity, wherein one end of the hydraulic cavity is provided with a piston system, the other end of the hydraulic cavity is provided with two one-way valve structures, the piston system comprises a piston and a traction rod, the piston is positioned in the hydraulic cavity, the traction rod penetrates through one end of the hydraulic cavity to be connected with the piston, the inlet directions of the two one-way valve structures are opposite, an annular rail framework is arranged in a position near the traction rod part, the annular rail framework is divided into an outer frame and an inner frame, an inner frame gear strip is fixedly arranged on one side, near the traction rod, of the inner frame, a traction rod gear strip is fixedly arranged on one side, near the inner frame, of the traction rod, and a movable gear used for lifting the traction rod in a rolling way is arranged between the inner frame gear strip and the traction rod gear strip. Compared with the prior art, the manual feeding and returning two-way hydraulic system has the advantages that the movable gear is used for manually operating to drive the traction rod to move, and the small-scale and low-speed hydraulic power output operation and control is realized.
Description
technical field [0001] The invention relates to a manual forward and return hydraulic system, in particular to a manual forward and return bidirectional hydraulic system. Background technique [0002] In the development of modern industrial technology, the development of hydraulic control systems has been very mature. In various production workshops, we can often see some large-scale, high-power hydraulic systems. These hydraulic control systems are often mechanized and pipelined. , the process and return of these hydraulic control systems reach the maximum displacement to obtain the maximum output power to adapt to some large-volume production, but in some small-scale production and some production activities with strong manual operation, this large-scale high-power The advanced hydraulic control system seems to be overqualified, and it cannot meet the effect of manual fine-tuning, and the control of some detailed operations is poor. [0003] In some small factories, we ca...
