Abstract

The invention discloses a rack-based concrete pumping device. The device comprises a workbench, a first cylinder body, a second cylinder body, a gear set and a rack; the first cylinder body and the second cylinder body are arranged on the workbench in parallel at intervals, pistons are arranged in the first cylinder body and the second cylinder body correspondingly, and driving rods extending to the corresponding rear of the first cylinder body or the corresponding rear of the second cylinder body are arranged at the tail parts of the pistons; the gear set is arranged on the workbench and located between the two driving rods, and the gear set comprises a driving gear and a driven gear meshing on the two sides of the driving gear; and the rack is arranged on one side of the driving rod andmeshes with the corresponding driven gear. By this way, according to the rack-based concrete pumping device, through the cooperation between the gear set and the rack, reverse movement of the pistonsin the first cylinder body and second cylinder body is achieved, the action precision is high, the high-speed movement of the pistons is facilitated, and the concrete pumping efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of concrete pumping, in particular to a rack-based concrete pumping device. Background technique [0002] The pumping of concrete usually uses the oil cylinder to drive the delivery cylinder to realize the pumping of concrete in the delivery cylinder. In order to improve the pumping efficiency, two conveying cylinders can be used to work alternately, and the medium is distributed through the medium distribution valve to realize continuous pumping of the medium. [0003] The invention patent application with the application number 201611048041.3 discloses a concrete pump, which uses two main oil cylinders to drive the two conveying cylinders, which consumes a lot of energy, and the control of the two main oil cylinders is relatively complicated, and it is difficult to accurately realize the high speed of the conveying cylinders. Collaborative, pumping is inefficient and needs improvement. Contents of the i...
