Description

Technical Field

[0001] The present invention relates to a transfer and lifting device on a logistics conveyor line, and particularly to a lifting device arranged at the transfer point on a heavy-duty conveyor line with a docking height of only 300 millimeters. Background Art

[0002] The transfer and lifting device on a heavy-duty conveyor line is used for the transfer of logistics transportation. Its working principle is as follows: when the material to be transported in the left-right direction is transported to the transfer position, the lifting mechanism raises the transport working surface to a specified height, and then the conveyor line mechanism in the front-back direction transports the object to be conveyed to a specified position in the other direction; therefore, the lifting device needs to be nested between two cross-conveyor devices, and the lifting device requires a large space. Especially when the weight of the object to be conveyed exceeds 1 ton, in order to meet the requirements of the lifting weight, generally hydraulic scissor-type, rack and pinion and other structures are used. These structures have the characteristics of complex structure, harsh environment, and large occupied space. When encountering a design space with a maximum lifting space of 300 millimeters, the above structures cannot meet the layout requirements of the electric drive lifting device. How to design a compact heavy-duty lifting device that can meet the lifting requirements of more than 1 ton has become a problem to be solved. Summary of the Invention
