AI Technical Summary

⚠Technical Problem

During the construction phase at the bottom of the mine shaft, the bucket hoisting device has safety issues, especially when workers may be operating above the bucket. Falling stones, concrete debris, and other objects may hit personnel. In addition, there may be undetected loose rocks during the shaft excavation process, leading to safety hazards.

⚗Method used

A bucket hoisting device for the bottom of a mine was designed, including a hoisting mechanism, a transmission mechanism, and a lifting mechanism. It is equipped with anti-fall components, a blocking component, and a weight sensor. Through motor-driven gear meshing and linkage mechanism, it realizes automated safety protection of the bucket during the hoisting process of materials and personnel, preventing falls and material imbalance.

🎯Benefits of technology

The system automatically closes the bottom inlet and outlet when lifting materials, ensuring even material distribution and preventing rotation and swaying; it also automatically closes the top inlet when lifting personnel to prevent injury from falling objects; ensuring that personnel are enclosed inside the bucket during the lifting process to prevent accidental falls, making the lifting process safer.

Abstract

This invention discloses a bucket lifting device and method for use at the bottom of a mine shaft, relating to the field of bucket lifting technology. It includes a lifting mechanism with a transmission mechanism on one side and a hoisting mechanism on the lower side of the transmission mechanism. A third motor's output rotates counterclockwise, driving a fourth gear to mesh with the third gear, indirectly causing the first and second circular baffles to rotate and open the feed inlet. Simultaneously, the rotation of the second rotating shaft causes the first connecting rod to swing, which in turn pushes the second connecting rod and the sliding column to slide along the arc-shaped groove, ultimately indirectly closing the personnel entrance / exit. This achieves the function of automatically closing the lower inlet / outlet and dividing the stone into two symmetrical, obliquely poured streams into the bucket when lifting materials, thus achieving uniform material distribution and preventing uneven loading. It effectively prevents safety hazards caused by uneven stone accumulation leading to bucket rotation, swinging, and collision with the shaft wall during lifting.
