Abstract

The invention belongs to a device for converting linear movement into rotating movement, and particularly relates to a double-hydraulic-cylinder acting rotating device and a double-hydraulic-cylinder acting hydraulic control system. The rotating device and the hydraulic control system solve the problem that the existing mechanism for converting linear movement into rotating movement has great space and cannot form permanent sustainable rotating movement. The double-hydraulic-cylinder acting rotating device comprises a 90-degree crankshaft, wherein the 90-degree crankshaft is provided with two shafts, the shaft surfaces of the two shafts of the 90-degree crankshaft are arranged in a way of forming 90 degrees, and the two shafts of the 90-degree crankshaft are respectively connected with a rotating oil cylinder a and a rotating oil cylinder b.

Description

technical field [0001] The invention belongs to a device for converting linear motion into rotary motion, in particular to a double hydraulic cylinder acting rotating device and a double hydraulic cylinder acting hydraulic control system. Background technique [0002] At present, the mechanisms that convert linear motion into rotary motion include rack and pinion type, rope pulley type, etc. [0003] 1. The above-mentioned mechanism often requires a large space, and cannot form a permanent and sustainable rotational motion, and cannot form a huge braking torque at any point by itself, so the applicable range is narrow. [0004] 2. It is easy for the crankshaft to convert the rotary motion into a linear motion, but it is difficult to apply it to practical engineering because of the existence of the stop point. [0005] 3. In order to solve the dead point problem, the present invention converts the linear motion of the two hydraulic cylinders into a stable, sustainable and ...
