A thin four-way shuttle

Abstract

The invention discloses a thin four-way shuttle car, which includes a car body and a driving motor. The car body is formed by alternately enclosing two end plates and two side plates. There is a reserved gap between the plates; four sets of front and rear travel wheels are symmetrically connected between the base plate and the end plates on both sides, and four sets of left and right travel wheels are fixed on both sides of the side plate of the car body; the drive motor is arranged on the base plate, and the drive motor It is used to drive the front and rear travel wheel sets and the left and right travel wheel sets alternately; the hydraulic drive mechanism is also fixed on the car body. The hydraulic drive mechanism drives the front and rear travel wheel sets to move up and down through the reserved gap and drives the pallet on the car body to move up and down. The present invention is that the traveling wheels of one direction of the four-way shuttle are arranged inside the car body of the four-way shuttle, and on the premise that the functions of the four-way shuttle can be realized, the arrangement of internal components is more reasonable, so that The four-way shuttle can reduce the thickness.

Description

technical field [0001] The invention discloses a thin four-way shuttle, which belongs to the field of intelligent storage. Background technique [0002] In recent years, with the advancement of science and technology, the continuous innovation of production equipment has improved the efficiency of production. The automated three-dimensional warehouse has been widely used in the field of production and logistics by virtue of its high space utilization rate and intelligent inbound and outbound. The application rate is increasing year by year. [0003] In the next few years, the automated three-dimensional warehouse will develop rapidly in the direction of higher space utilization, faster and smarter storage and storage efficiency, and greater storage density of goods. [0004] Based on the three-dimensional warehouse with high space utilization, on the premise of the same warehouse area, increasing the number of floors of the warehouse as much as possible has become the only ...

AI Technical Summary

Problems solved by technology

[0005] Today, the four-way shuttles on the market are mainly divided into two ways to realize the pallet lifting function and reversing function of the four-way shuttle: one is realized by driving the cam with a motor, and the main factor limiting its thickness is the cam and the camshaft. In the heavy-duty environment, the weight of the cargo is mainly borne by the various bearings arranged on the camshaft, so the diameter of the camshaft limits the size of the bearing and the bearing seat, resulting in a thicker four-way shuttle that uses the cam, which cannot protrude Show the superiority of the three-dimensional warehouse;

[0006] It is also realized by motor-driven hydraulic cylinders. The hydraulic cylinders make linear reciprocating motions under the drive of the motors. The thickness of the four-way shuttle is mainly determined by the length of each hydraulic cylinder and the stroke of the piston rod inside the hydraulic cylinder, but the valve block that controls the hydraulic system Hydraulic components such as hydraulic motors and fuel tanks occupy a large amount of space inside the four-way shuttle, resulting in limited space inside the four-way shuttle, which requires reducing the size of other modules such as control modules and power modules, by sacrificing some functions or battery capacity, etc. way to save enough space to give the hydraulic system layout
