High-speed stirring-squeezing trolley

Abstract

The invention discloses a high-speed stirring mud grouting trolley and is characterized in that: the high-speed stirring mud grouting trolley is provided with a frame, and the frame is equipped with a screw conveying mechanism, a high-speed stirring mechanism, a grout pump and a controller. The high-speed stirring mechanism is composed of a high-speed stirring drum, a bracket and a high-speed stirring motor. The inlet of the grout pump is communicated with the high-speed stirring drum by a pipeline. The bracket is provided with at least three pillars, and the lower ends of the pillars are fixed on a trolley board, while the upper ends thereof are connected with the bottom of the stirring drum by a weighting sensor. The output shaft of the high-speed stirring motor faces upwards and penetrates into the high-speed stirring drum, and the end of the output shaft is provided with blades. The screw conveying mechanism is fixed on the trolley board in an oblique manner in virtue of the bracket, the end of the the discharge hole of the screw conveying mechanism is communicated with the feeding hole of the high-speed stirring drum, and the feeding hole is provided with a feeding funnel. Automatic control of each part can be realized by the controller. The high-speed stirring mud grouting trolley of the invention not only can save time and improve production efficiency, but also can evenly mix grouting agents and can guarantee the quality of bridges. The high-speed stirring mud grouting trolley is suitable for preparing grouting agents and filling the grouting agents in pipelines.

Description

technical field [0001] The invention relates to a concrete mixer. Specifically, it is a high-speed mixing and grouting trolley used to prepare the grouting agent and pour the grouting agent into the pipeline. It is especially suitable for mixing the grouting agent at high speed in bridge construction and pouring it into the pipeline. Background technique [0002] It is well known in the field of bridge construction that the protection of prestressed steel bars in prestressed bridges is crucial to the safety of prestressed bridges. The protection of prestressed steel bars of post-tensioned prestressed bridges mainly comes from the quality and reliability of prestressed pipeline grouting, and the quality of pipeline grouting agent and grouting process are the main factors affecting the quality and reliability of pipeline grouting. The pipeline grouting agent is made by dry-mixing the grouting material with high-efficiency water reducer, micro-expansion agent, mineral admixtur...

AI Technical Summary

Problems solved by technology

Relying on manual control, although the grouting agent can be mixed and tanked, it takes a long time to mix, the production efficiency is low, and it is difficult to mix evenly, and even water lumps will appear in the grouting agent, which cannot guarantee the bridge quality of railway bridges

In addition, due to relying on manual control, the size of the grouting pressure and the length of the holding time are completely based on the experience of the construction personnel and are greatly affected by human factors. This will also affect the quality of bridges, especially railway bridges.

On the other hand, it is cumbersome to operate due to the manual control from feeding and stirring to the completion of the tank slurry.
