Abstract

The invention relates to a composite linkage type double-cylinder system. The composite linkage type double-cylinder system is characterized by comprising a first driving cylinder, a second driving cylinder, fixed seats and a movable seat. According to the composite linkage type double-cylinder system, composite motion adopting the double cylinders is achieved by adopting the first driving cylinder and the second driving cylinder, the two ends of the first driving cylinder are utilized to be matched with the first fixed seat and the movable seat correspondingly, the first driving cylinder drives the movable seat to achieve angle adjustment of the second driving cylinder, the second driving cylinder is utilized to be assembled with the second fixed seat, and rectilinear motion of a movableblock connected to the second driving cylinder is achieved through the second driving cylinder; and double-cylinder composite linkage is achieved through combination of the first driving cylinder andthe second driving cylinder, the composite linkage type double-cylinder system has the advantages that the speed of synchronous telescopic movement is high, and no grade-changing vibration is generated, and rapid and smooth motion of a load can be achieved.

Description

technical field [0001] The invention relates to the field of hydraulic cylinders, in particular to a composite linkage double-cylinder system. Background technique [0002] At present, the multi-stage hydraulic cylinder widely used in China is a synchronous telescopic cylinder. Its main structure (take the two-stage synchronous telescopic cylinder as an example) includes: multi-stage cylinder block, one-stage cylinder, two-stage cylinder, one-way valve, etc. The rod chamber of the first-stage cylinder communicates with the rodless chamber of the second-stage cylinder. When the first-stage cylinder moves, the hydraulic oil in the rod chamber of the first-stage cylinder is squeezed into the rodless chamber of the second-stage cylinder, thereby realizing the first-stage cylinder. It moves synchronously with the secondary cylinder. The one-way valve is installed in the piston center of the primary cylinder, and is used for synchronous compensation when the synchronization betw...
