A cross-directional reversing structure for shelving travel tracks

Abstract

This utility model discloses a cross-directional reversing structure for shelving travel tracks. The cross-directional reversing structure includes a main track bar mounted on an upright. The surface of the main track bar is recessed downward to form a clearance groove. The reversing track bar is at least partially engaged in the clearance groove. The main track bar and the reversing track bar are arranged perpendicularly. Support bars are provided on multiple uprights located on the same side. The main track bar is mounted on the support bars. The bottom wall of the clearance groove is provided with a perforation. A support column is provided on the upper surface of the support bar. The support column passes through the perforation and contacts the reversing track bar. This solves the problem in the prior art where the cross-directional reversing part of the shelving requires a clearance groove for one of the tracks, resulting in a decrease in the strength of that part and easy deformation of the edge of the clearance groove under pressure after long-term use.

Description

Technical Field

[0001] This utility model relates to the field of warehouse racking, specifically to a racking travel track cross-directional reversing structure. Background Technology

[0002] To facilitate the movement of the four-way shuttle, not only are longitudinal tracks laid in the racking aisles, but transverse tracks are also laid between each storage location on each rack level. The four-way shuttle can change direction at the intersection of the longitudinal and transverse tracks to reach different storage areas. For example, Chinese patent CN221970412U provides a mother track cooperation structure for a four-way shuttle car and its travel track in an automated warehouse. The automated warehouse includes vertical racks and multiple storage layers arranged on the vertical racks. The storage layers are equipped with horizontal cross tracks for the four-way shuttle car to travel on, including: mother track travel wheel sets that can be raised and lowered and are respectively set on opposite sides of the frame of the four-way shuttle car. The mother track travel wheel sets include multiple mother travel wheels with wheel edges set on the inner side; a mother rail in the horizontal cross track for the mother track travel wheel sets to travel on, wherein the mother travel wheels travel along the mother rail with their wheel edges abutting against the inner side of the mother rail; a reversing track structure similar to the above-mentioned prior art, wherein the sub-tracks are provided with clearance grooves for the engagement of the mother rails. In the prior art, in order to reduce the weight of the racks, the tracks are generally hollow structures. The clearance grooves on the sub-tracks will reduce the strength of this part, and the edge of the clearance groove is prone to deformation under pressure after long-term use. Utility Model Content

[0003] The purpose of this utility model is to provide a cross-directional reversing structure for shelving travel tracks, which solves the problem that in the existing technology, the cross-directional reversing part of the shelving needs to have an avoidance groove, which leads to a decrease in the strength of that part and the edge of the avoidance groove is prone to deformation under pressure after long-term use.

[0004] To achieve the above objectives, this utility model provides a cross-directional reversing structure for a shelf travel track. The cross-directional reversing structure for a shelf travel track includes a main track bar set on an upright. The surface of the main track bar is recessed downward to form a relief groove. The reversing track bar is at least partially engaged in the relief groove. The main track bar and the reversing track bar are arranged perpendicularly.

[0005] Support bars are provided on multiple columns located on the same side, the main track is provided on the support bars, the bottom wall of the clearance groove is provided with a perforation, and a support column is provided on the upper surface of the support bar. The support column passes through the perforation and contacts the reversing track.

[0006] Preferably, the support column is provided with a U-shaped clamp, and the reversing track bar is at least partially engaged in the U-shaped clamp.

[0007] Preferably, the length of the clearance groove is greater than the width of the reversing track bar;

[0008] The reversing track is centered within the clearance groove.

[0009] Preferably, a screw hole is formed on the support column, a countersunk hole is formed on the surface of the U-shaped clip, and the locking screw passes through the countersunk hole and is screwed into the screw hole.

[0010] Preferably, the support bar has an L-shaped cross-section, the vertical section of the L-shaped structure is locked to the column by a screw assembly, and the main track bar is placed on the horizontal section of the L-shaped structure.

[0011] Preferably, the outer side of the horizontal section of the L-shaped structure is bent upwards to form a bent portion;

[0012] The main track bar is located between the column and the bend.

[0013] Preferably, multiple reinforcing ribs are provided between the horizontal and vertical sections of the L-shaped structure.

[0014] Beneficial Effects: This utility model provides a cross-directional reversing structure for shelving tracks. The structure includes a main track bar mounted on uprights, with a recessed clearance groove on its surface. At least a portion of the reversing track is engaged within this groove. The main track bar and the reversing track bar are perpendicularly arranged. Support bars are mounted on multiple uprights on the same side, with the main track bar mounted on the support bars. The bottom wall of the clearance groove has a perforation, and a support column is mounted on the upper surface of the support bar, passing through the perforation and contacting the reversing track bar. The cross-directional reversing structure provided by this utility model, with support bars on the uprights, effectively supports the clearance groove portion of the main track bar, increasing the structural strength of adjacent sections. Simultaneously, the support bars have support columns extending into the clearance groove, effectively supporting the reversing track and preventing deformation of the clearance groove edge due to stress. This solves the problem in the prior art where tracks are generally hollow, leading to a decrease in structural strength of related parts and long-term deformation of the clearance groove edge due to pressure.
