Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete transportation, in particular to a concrete pumping device. Background Art
[0002] In modern construction, concrete pumping technology has become an indispensable part, which greatly improves construction efficiency, especially in high-rise buildings, large-volume concrete pouring and other projects. Concrete pumping devices transport concrete to designated locations through pipelines, replacing traditional manual or mechanical transportation methods, reducing labor demand and speeding up construction progress. However, concrete mixtures contain components such as aggregates of different sizes, sand, cement and water. If they are directly pumped without effective treatment, they are prone to problems such as pumping blockage, increased wear and unstable pumping quality.
[0003] Traditional concrete pumping devices often ignore the pretreatment of concrete raw materials and the protection measures of the equipment itself during the pumping process. Unfiltered concrete may contain oversized particles or foreign matter. These impurities will not only cause wear and tear on the inside of the pump body during the pumping process, but may also clog the pipeline, seriously affecting the pumping efficiency and the quality of concrete pouring. At the same time, the concrete pump will produce large vibrations when working. Long-term vibrations will not only affect the pumping accuracy, but also shorten the service life of the equipment and increase maintenance costs. Therefore, we propose a concrete pumping device.
