Lifting mechanism for shuttling tool

Abstract

The invention relates to a lifting mechanism for a shuttling tool, and belongs to the technical field of storage and taking. The lifting mechanism comprises a lifting bottom seat and a lifting top seat, wherein the lifting bottom seat is fixed on a bottom frame of the shuttling tool; the lifting top seat is fixedly connected with a tray top plate and positioned above the lifting bottom seat; the lifting bottom seat and the lifting top seat are respectively provided with paired synchronous gears which are meshed with each other, and the rotating centers of the synchronous gears are positioned on the same horizontal line; the rotation centers of the synchronous gears are respectively and fixedly connected with one ends of each of a pair of lower rocker arms and a pair of upper rocker arms; the other end of each of the lower rocker arms and the other end of each the upper rocker arms are correspondingly connected with each other respectively; one of a pair of hinged parts of the lower rocker arms and the upper rocker arms is hinged with one end of a driving connection rod; and the other end of the driving connection rod is hinged with the outer end of a crank driven by a speed reduction output power device. Due to multiple self-locking, the locking is relatively reliable; and furthermore, due to the two pairs of synchronous gears, the pair of lower rocker arms and the pair of upper rocker arms form the symmetric lifting mechanism which is stressed in a balanced manner and runs steadily.

Description

technical field [0001] The invention relates to a lifting mechanism for a shuttle vehicle, in particular to a lifting mechanism for a cargo storage and retrieval shuttle vehicle, and belongs to the technical field of warehousing and freight transportation. Background technique [0002] The shuttle car is a commonly used cargo storage and retrieval equipment matched with the dense shelves in the warehouse, including a lifting mechanism on the walking system. The equipment can be used to carry out the operation of goods in place. According to the applicant's knowledge, the lifting mechanisms of existing shuttle vehicles include eccentric gear lever mechanisms, cam mechanisms, or worm gear mechanisms. None of these mechanisms can avoid the disadvantages of unreliable self-locking, high starting torque, and high power consumption. Therefore, during the movement of the shuttle, the lifting mechanism that should always maintain the state of jacking up the pallet will occasionally...

AI Technical Summary

Problems solved by technology

None of these mechanisms can avoid the shortcomings of unreliable self-locking, large starting torque, and high power consumption. Therefore, during the movement of the shuttle, the lifting mechanism that should always keep the pallet up will occasionally drop, posing a safety hazard.

In addition, the parts are more complicated and the manufacturing cost is high
