[0003] However, the main oil cylinder of the existing pumping system is a single-stage oil cylinder, the concrete pumping volume is small, and the pumping efficiency is low
Moreover, the length of the main oil cylinder is too large in the length of the pumping system, which restricts the length of the delivery cylinder
At the same time, due to the constraints of the installation space of the chassis, the length of the main oil cylinder, and the length of the delivery cylinder, the inclination angle of the pumping system is too large, which is not conducive to the suction of concrete

Abstract

The invention provides a pumping system and a pumping machine. The pumping system comprises a main oil cylinder and a locking mechanism. Multiple stages of oil cylinders are embedded into the main oil cylinder, a piston rod of the previous stage of oil cylinder is a cylinder barrel of the next stage of oil cylinder, and a piston of the next stage of oil cylinder is located in a cylinder barrel of the previous stage of oil cylinder. Rodless cavities of all the stages of oil cylinders communicate with each other, and rod cavities of all the stages of oil cylinders communicate with each other. The locking mechanism is used for closing or opening the rod cavities of all the stages of oil cylinders to control the action sequence of the multiple stages of oil cylinders, and therefore the piston rods of all the stages of oil cylinders act in order, and stable and reliable operation of the system is guaranteed. In the one-time pumping process, when the piston rod of the previous stage of oil cylinder moves to the limit position, the piston rod of the next stage of oil cylinder starts to move, the concrete pumping amount is greatly increased, and the pumping efficiency is improved. The multiple stages of oil cylinders are arranged, and therefore the ratio of the length of the main oil cylinder to the length of the pumping system can be reduced, the space is reasonably utilized, the ratio of the length of a conveying cylinder to the length of the pumping system is increased, the inclination angle of the pumping system can also be reduced, and the material suction performance of the pumping system is improved.

Description

technical field [0001] The invention relates to the technical field of concrete pumping equipment, in particular to a pumping system and a pumping machine. Background technique [0002] The concrete pump truck is a machine that uses pressure to continuously transport concrete along the pipeline, and is composed of a pumping system and a pipeline. [0003] However, the main oil cylinder of the existing pumping system is a single-stage oil cylinder, the concrete pumping volume is small, and the pumping efficiency is low. Moreover, the length of the main oil cylinder accounts for too much in the length of the pumping system, which restricts the length of the delivery cylinder. At the same time, due to the constraints of the installation space of the chassis, the length of the main oil cylinder, and the length of the delivery cylinder, the inclination angle of the pumping system is too large, which is not conducive to the suction of concrete. Contents of the invention [000...
