Cam lifting type sixteen-wheel four-way shuttle vehicle

Abstract

The invention discloses a cam lifting type sixteen-wheel four-way shuttle vehicle which comprises a supporting frame, a transverse walking driving mechanism, a longitudinal walking driving mechanism and a cam reversing and jacking mechanism, the cam reversing and jacking mechanism comprises a jacking transverse plate, a jacking shaft and cable-stayed jacking sliding blocks, the cable-stayed jacking sliding blocks on the front side and the rear side are eccentrically connected with transmission cams through connecting rods correspondingly, the two transmission cams on the left side and the right side are connected with a center straight gear in a meshed mode, and the center straight gear is connected with a longitudinal output shaft of a cross-shaped speed reducer. According to the cam reversing and jacking mechanism, the linkage lifting action of the jacking shaft is achieved in the linkage mode of the transmission cams and the cable-stayed jacking sliding blocks, the transmission efficiency is high, and the pressure angle is not changed; the cable-stayed jacking sliding blocks arranged at the four corners are connected through the two transmission cams, stress is uniform, and structure operation is stable; and the cam reversing and jacking mechanism and the transverse walking driving mechanism are in linkage control and share one driving motor, so that the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a four-way shuttle, in particular to a cam lift type sixteen-wheel four-way shuttle. 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. The lifting mechanism of the existing shuttle car includes eccentric wheel lever mechanism, cam mechanism, or worm gear mechanism. Uniformity and low transmission efficiency, large power consumption, high manufacturing cost and other defects. [0003] In addition, most of the existing shuttle vehicles adopt a two-way 8-wheel structure design, which has weak crossing ability and high failure rate. It not only occupies a considerable space, reduces the number of shelves and compartments, but also reduces the space utilization rate of the three-dimensional warehouse. It al...

The lifting mechanism of the existing shuttle car includes eccentric wheel lever mechanism, cam mechanism, or worm gear mechanism. Uniformity and low transmission efficiency, large power consumption, high manufacturing cost and other defects

[0003] In addition, most of the existing shuttle vehicles adopt a two-way 8-wheel structure design, which has weak crossing ability and high failure rate. It not only occupies a considerable space, reduces the number of shelves and compartments, but also reduces the space utilization rate of the three-dimensional warehouse. It also increases the cost of manufacturing, procurement and maintenance, which can no longer meet the increasingly busy needs of warehousing and logistics
