AI Technical Summary
Traditional heavy lifting devices are prone to increased gaps due to wear during the lifting process, causing the lifting trajectory of the heavy object to deviate. In addition, ordinary flat guide wheels are difficult to balance the lateral load, which can easily cause the chain to swing laterally or derail.
The rolling action of the "V"-shaped guide wheel and the diamond-shaped bracket limits the lateral offset and tilting of the lifting component, ensuring that the load moves stably along the preset vertical trajectory, and absorbs instantaneous impacts and vibrations through the buffer.
It effectively limits the lateral deviation and tilting of the heavy object, ensuring that the heavy object moves stably along the preset vertical trajectory, and reducing the risk of shaking during start-up and shutdown and sudden load changes.

The traditional heavy lifting device usually adopts a guide rail-sliding block or a planar guide wheel structure to realize vertical motion constraint, but in actual application, the traditional sliding block relies on sliding friction, and the gap is easily increased due to wear, causing the lifting trajectory of the heavy object to deviate. Although the ordinary planar guide wheel can reduce friction, the single-point contact mode is difficult to balance the lateral load, especially under heavy load or dynamic impact working conditions, which easily causes chain lateral swing or even derailment risk.
[0003] Therefore, how to provide a heavy lifting guide mechanism, which can limit the lateral deviation and tilting swing of the lifting assembly, and ensure the stable movement of the heavy object along the preset vertical trajectory has become a technical problem to be solved urgently.

[0008] The support frame is provided with a rhombic support corresponding to the V-shaped guide wheel structure, and the V-shaped guide wheel is in rolling cooperation with the rhombic support.
[0009] The rolling cooperation between the V-shaped guide wheel and the rhombic support can limit the lateral deviation and tilting swing of the lifting assembly at the same time, and ensure the stable movement of the heavy object along the preset vertical trajectory. At the same time, the rolling cooperation can absorb the instantaneous impact or vibration in the lifting process, and suppress the shaking of the heavy object, especially at the start-up and shutdown stages or when the load suddenly changes.
