Problems solved by technology

The one-piece oil cylinder structure is made by integrally processing two cylinder barrels on an integral forging, casting or weldment. The structure of this one-piece oil cylinder is complex and needs to be processed after integral forging. The processing is difficult, and it is not easy to ensure the two cylinder barrels Coaxiality, the overall weight is relatively large

Abstract

The invention provides a hydraulic cylinder, which is used for a material pumping system. Rod chamber ends or rodless chamber ends of a first cylinder barrel and a second cylinder barrel are connected through an integrated gland; or a rod chamber end and a rodless chamber end of each of the first cylinder barrel and the second cylinder barrel are connected through one integrated gland. The invention further provides the material pumping system and material pumping equipment. The integral rigidity of the hydraulic cylinder is enhanced so that vibration resistance and impact resistance of the hydraulic cylinder is improved, axial distance between the two cylinder barrels of the hydraulic cylinder is decreased, the integral structure of the hydraulic cylinder is more compact, and occupied space of the hydraulic cylinder is decreased. The axial distance between the two cylinder barrels of the hydraulic cylinder is further decreased, so that an 'S'-shaped pipe valve is lowered, and flow resistance of concrete and swing resistance of the 'S'-shaped pipe valve are reduced. Compared with the prior art, the concrete pumping system and a concrete pump are more compact in structure, small in occupied space, convenient in mounting and light in total weight.

Description

technical field [0001] The present invention relates to engineering machinery, and more specifically, to a hydraulic cylinder, a material pumping system containing the hydraulic cylinder, and material pumping equipment containing the material pumping system. Background technique [0002] In the prior art, the concrete pumping system includes two main oil cylinders, the central axes of the two main oil cylinders are parallel to each other, the main oil cylinder piston and the main oil cylinder piston rod connected to it are respectively arranged in the main oil cylinder, and the main oil cylinder piston rod and the delivery cylinder The concrete piston in the connection is connected; when the piston of the main oil cylinder reciprocates under the drive of the hydraulic system, it can drive the concrete piston to reciprocate in the delivery cylinder to realize the concrete suction and pumping action. [0003] Such as figure 1 Shown is a schematic structural view of an indepen...
