Rotary orbit shuttle device

Abstract

The invention relates to a transition shuttle device, comprising a supporting frame (1). The transition shuttle device is characterized in that a transverse front support (2) and a rear support (3) are connected with the supporting frame via a rotary supporting shaft (4); two steering devices are arranged outside the front support and the rear support; two travelling wheels (5) driven by a travelling motor (7) are symmetrically arranged at two ends; each steering device comprises two fixed guide wheels (6) arranged on two sides of each travelling wheel, a rotary disk (15) arranged on a base and driven by a steering motor (9) to rotate along an axis (16), two link mechanisms (13, 14) hinged with the rotary disk, and two tumblers (11, 12) hinged at two ends of the link mechanism; one end of the tumbler is arranged on a stationary shaft (17), while a movable guide wheel (10) is arranged at the other end. The transition shuttle device has the advantages of steering and transition function, capability of automatically freely driving on the straight track and curved track, simple structure, reliability, and small volume.

Description

technical field [0001] The invention belongs to the technical field of logistics equipment machinery, and in particular relates to a steering device for a material handling vehicle. Background technique [0002] In the automated logistics system, most of the existing tracked material handling vehicles do not have the functions of turning and branching, and cannot switch tracks by themselves. They can only run on straight tracks and cannot automatically turn on curves. In practical applications, there are some vehicles that can switch tracks on tracks with forks, but the track switch does not mean that the vehicle itself has a track switch function, but that after the track is pulled by an external force, the wheels walk along the artificially guided track. This method of turning by changing the track route has at least the following deficiencies: first, the design of the track structure is more complicated, and second, it needs manual or control system to frequently pull the...

Problems solved by technology

This method of turning by changing the track route has at least the following deficiencies: first, the design of the track structure is more complicated, and second, it needs manual or control system to frequently pull the branch to control the driving route of the vehicle, which affects work efficiency and increases The process of automatic control cannot meet the needs of a modern and efficient logistics system

There are also some manufacturers that use track trolleys that can actively steer or switch tracks, but the steering or track switching needs to rely on a complex pneumatic mechanism to complete, and air compression equipment needs to be added to the vehicle, which requires high power and has a complex and huge structure.
