Embodiment Construction

[0018] The present invention is further elaborated below by specific embodiment:

[0019] Such as figure 1 and figure 2 shown (for convenience, refer to figure 1 direction shown), the compact oil cylinder hydraulic drive system of the present invention includes a base 80, a fuel tank 10, a main valve block 81, a transition connection block 82, an AB oil port valve block 83, a two-way hydraulic lock 84, and a one-way throttle valve group 85. Proportional reversing valve 86.

[0020] Wherein, the main valve block 81 is installed on the base 80 . The left surface of main valve block 81 is fixed with submerged oil pump 11, oil return pipe 61, oil tank 10 and oil suction pipe 62. The oil inlet of the submerged oil pump 11 communicates with the oil suction pipe 62 through the flow channel in the main valve block. A motor 63 for driving the submerged oil pump 11 is fixed on the right surface of the main valve block 81 . An air filter 64 is also installed on the top of the fuel...

Abstract

The invention provides a compact type oil cylinder hydraulic driving system. The compact type oil cylinder hydraulic driving system comprises a main valve block, a transition connection block, a mainshaft braking valve group and a yawing braking valve group; an immersion type oil pump, an oil returning pipe, an oil tank and an oil absorbing pipe are fixed to the left surface of the main valve block; the oil tank is of a cylindrical structure, and covers the immersion type oil pump, the oil returning pipe and the oil absorbing pipe; an oil inlet of the immersion type oil pump communicates withthe oil absorbing pipe through a flow channel in the main valve block; a motor driving the immersion type oil pump to work is fixed to the right surface of the main valve block; the upper end face ofthe main valve block is connected with the transition connection block; and the main shaft braking valve group and the yawing braking valve group are further connected to the transition connection block. The compact type oil cylinder hydraulic driving system has the main shaft braking function and the yawing braking function, achieves integration of various hydraulic elements through the main valve block and the transition connection block, and further has the beneficial effect of being compact in structure.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a compact hydraulic drive system for an oil cylinder. Background technique [0002] Hydraulic systems are widely used in construction machinery, machine tools, vehicles and other fields because they can do work effectively. One of the most important uses of hydraulic systems is to drive cylinders to work. The driving cylinder usually requires a large thrust, a stable thrust, and a flow adjustment function. In the prior art, the hydraulic drive system of the oil cylinder needs to be realized by a complex hydraulic station, which has a large structure and takes up a lot of space, and is not suitable for occasions where the installation space is small. Contents of the invention [0003] The problem to be solved by the present invention is to provide a cylinder hydraulic drive system with large thrust, stable flow, simple structure and compact structure, so as to overcome the shortcomings of...
