Abstract

The invention relates to a composite linkage double-cylinder system, which is characterized in that it includes a first driving cylinder, a second driving cylinder, a fixed seat and a movable seat; The two ends of a driving cylinder cooperate with the first fixed seat and the movable seat respectively, and the first driving cylinder drives the movable seat to realize the angle adjustment of the second driving cylinder, and the assembly of the second driving cylinder and the second fixed seat is used to realize the angle adjustment of the second driving cylinder by the second The drive cylinder realizes the linear motion of the movable block connected to the second drive cylinder, and the combined movement of the first drive cylinder and the second drive cylinder realizes the compound linkage of the two cylinders, the advantages of fast synchronous telescopic movement speed and no vibration of stage change, which can be Achieve fast and smooth movement of loads.

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...
