AI Technical Summary

Technical Problem

During the pumping of high-toughness concrete, uneven material distribution within the pipeline can lead to localized siltation, which can easily cause blockages and pipe wall wear. Existing equipment cannot adaptively adjust to these conditions, affecting construction efficiency and safety.

Method used

The main body adopts an anti-clogging and anti-wear device. The anti-clogging central frame guides the concrete to converge towards the center of the pipe axis. Combined with the hidden plate, it forms an isolation and protective layer. It is fixed by using an annular threaded groove and a limit frame. The control plate adjusts the spring tension to achieve adaptive adjustment and double fixation.

Benefits of technology

It effectively reduces the probability of blockage, improves the uniformity of material distribution, prevents pipe wall wear, improves construction efficiency and safety, and is easy to operate and reliably fixed.

Abstract

The application discloses a high-toughness concrete pumping pipeline anti-blocking and anti-abrasion device, and relates to the technical field of pipeline anti-blocking. The inside of the anti-abrasion plate is connected with a hidden plate for preventing the abrasion of the inner wall of the pipeline, the front end of the anti-abrasion plate is connected with a limiting frame for limiting the anti-blocking and anti-abrasion device body and the pipeline together, and the side of the mounting plate close to the inner wall of the anti-blocking and anti-abrasion device body is connected with a control plate for controlling the tightness of the anti-blocking and anti-abrasion device body. The application has the advantages that the anti-blocking and anti-abrasion device body is actively guided by the anti-blocking and anti-abrasion device body, and the concrete is gathered to the middle section of the pipeline axis, so that the distribution uniformity of the concrete in the pipeline cross section is improved; meanwhile, the anti-blocking and anti-abrasion device body can rotate around the rotating shaft freely, so that the effective radius of the pipeline passing section can be self-adaptively adjusted with the change of the concrete pumping power, and the blocking probability is greatly reduced under the premise of ensuring normal conveying.
