Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, and in particular to an intelligent self-balancing hoisting equipment for hoisting a prefabricated T-beam template. Background Art

[0002] T-beam is a common structural form in bridge engineering, and the installation and hoisting of its formwork is an indispensable and important part of the construction process. Traditional T-beam formwork hoisting mostly uses ordinary hoists or wire ropes to directly connect the formwork legs, which has problems such as low hoisting efficiency, poor balance, and easy damage to the formwork.

[0003] At present, most of the hoists on the market are of fixed size, and cannot adjust the width and center of gravity according to different specifications of T-beam templates. In addition, the existing hoists lack intelligent design and cannot accurately calculate and automatically adjust the center of gravity of the template, which makes it easy to tilt and be dangerous during the hoisting process. Therefore, we propose an intelligent self-balancing hoist for the hoisting of prefabricated T-beam templates. Summary of the invention

[0018] Furthermore, the mechanical sensing unit adopts a multi-axis mechanical sensing unit, and the motor drive module adopts a high-precision position and speed control servo motor.

[0019] Furthermore, the signal processing module uses an embedded processor with low-latency control to process the collected gravity distribution data, runs the control algorithm in real time, and adaptively adjusts the control parameters according to load changes, and determines the distance ΔL and direction that the motor needs to move based on calculations.

[0020] Furthermore, the counterweight block device includes counterweight lead blocks on both sides of the support frame, and the distribution of the counterweight blocks is adjusted according to the center of gravity position of the template through the motor drive module.
