AI Technical Summary

Technical Problem

In the existing concrete pumping equipment for ultra-high-rise buildings, the vertical conveying pipe is fixedly connected by multiple sections of pipelines, and the strength at the connections of adjacent pipelines is low, making it easy to cause pipeline damage.

Method used

An ultra-high-rise concrete pumping equipment is designed, which uses a vertical conveying pipe composed of multiple conveying single pipes, and a high-strength connection sleeve and connection flange are used at the connections of adjacent conveying single pipes to increase the strength at the connection.

Benefits of technology

By increasing the strength at the connections of adjacent conveying single pipes, the overall strength of the vertical conveying pipe is improved, the risk of pipeline damage is reduced, and friction resistance is reduced by lubrication and washing the pipe.

Abstract

The utility model relates to super high-rise concrete pumping equipment, which belongs to the technical field of concrete conveying and comprises a concrete pump, an upper conveying pipe, a lower conveying pipe and a vertical conveying pipe, the vertical conveying pipe is formed by connecting a plurality of conveying single pipes, and a rinsing pipe is arranged at the connecting end of the lower conveying pipe and the concrete pump. A first connecting flange is fixed to the connecting ends of every two adjacent conveying single pipes, a high-strength connecting sleeve is arranged outside the connecting position of every two adjacent conveying single pipes in a sleeving mode, second connecting flanges matched with the first connecting flanges are fixed to the two ends of each connecting sleeve, and a fixing sleeve is arranged outside each connecting sleeve in a sleeving mode. The high-strength connecting sleeve is sleeved at the joint of the adjacent conveying single pipes, and two ends of the connecting sleeve are fixedly connected with the first connecting flanges fixed on the conveying single pipes through the second connecting flanges, so that the strength of the joint of the conveying single pipes can be enhanced, the strength of the vertical conveying pipe is higher, the vertical conveying pipe is not easy to damage, the lower conveying pipe is provided with the rinsing pipe, and the rinsing pipe is convenient to clean. And a rinsing solution can be introduced for rinsing before conveying, so that the frictional resistance is reduced.
