AI Technical Summary

Technical Problem

Existing technologies require a large amount of manpower to control the discharge position of the hose during the concrete pouring process in the tunnel invert or outside the tunnel, resulting in uneven pouring and difficulty in subsequent smoothing, leading to low work efficiency.

Method used

The device employs a combination of positioning and pouring units, including a steering assembly, a propulsion assembly, a spiral track, and a support mechanism. The spiral rotation of the flexible guide tube is achieved by a motor-driven push rod and an arc-shaped slider, and the combination with a two-way trowel ensures uniform pouring and smoothing of concrete.

Benefits of technology

It achieves uniform pouring without the need for multiple people to control, reducing manpower consumption, improving work efficiency, and ensuring consistent pouring time and uniformity in each area, thus reducing subsequent leveling work.

Abstract

This invention discloses a concrete pouring auxiliary positioning device, including a pump pipe, a flexible guide tube inserted into the discharge end of the pump pipe, a pouring area located below the pump pipe, and a reinforcing steel frame installed above the pouring area. It also includes: a positioning unit comprising a steering component positioned above the reinforcing steel frame for switching the position of the flexible guide tube, and a propulsion component located on one side of the steering component for positioning and continuously moving the flexible guide tube; and a pouring unit comprising a spiral track for guiding the propulsion component and a support mechanism located on one side of the spiral track for supporting the spiral track. By driving a push rod to reverse direction via a drive shaft, the pouring pipe rotates in the opposite direction along the spiral track from the outside in until the arc-shaped slider returns to the center of the spiral track, at which point the drive motor stops rotating, and the pouring process ends. This achieves the effect of uniform pouring throughout the entire process, ensuring consistent pouring time for each pouring area.
