Description

Technical Field

[0001] The utility model relates to a traveling track of a shuttle car, and particularly to a ratchet structure for a traveling track of a heavy-duty shuttle car. Background Art

[0002] As an important logistics storage device, an automated stereoscopic warehouse shelf can cooperate with equipment such as shuttle cars, mother-and-child cars, four-way cars, stackers, and conveyors to complete the tasks of material picking, placing, and storing, and is applied in intelligent warehouse projects in various industries.

[0003] In heavy-duty shuttle car projects, the traveling track of the heavy-duty shuttle car is relatively long (most ≥ 6m), so the track needs to be designed and produced in sections, and the docking and matching of the sectional tracks are particularly important. If there is a slight deviation in the matching dimensions, at worst, the shuttle car will run with noise, and at best, the shuttle car will jolt, and the goods carried by the shuttle car may be displaced and dropped.

[0004] The existing docking method is to directly dock two C-shaped steels as two sections of the track, and this docking method is prone to the above problems. Therefore, it is necessary to design a ratchet structure for the traveling track of a heavy-duty shuttle car. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a ratchet structure for a traveling track of a heavy-duty shuttle car, which can meet the docking requirements of the traveling track of the heavy-duty shuttle car, has good flatness at the docking position of the track, and increases the traveling smoothness of the heavy-duty shuttle car on the track.

[0006] To achieve the above purpose, the utility model provides a ratchet structure for a traveling track of a heavy-duty shuttle car, which includes a hollow first track and a hollow second track docked with the first track. Both the first track and the second track are installed on a support member through first bolts. Female grooves are provided at the bearing surface, bottom surface, and side surface of the first track facing one end of the second track, and a convex portion that can fit and insert into the female groove is provided at the end of the second track facing the second track.

[0007] Preferably, a first side opening is provided on the side surface of the first track, a second side opening corresponding to the first side opening is provided on the side surface of the second track, first through holes are provided on the bottom surfaces of the first track and the second track, first bolts passing through the support member are arranged in the first through holes, and the outer ends of the first bolts are locked through first nuts.

[0008] Preferably, a plurality of right-angle reinforcement members are installed on the side surface of the first track near the first side opening and the side surface of the second track near the second side opening through second bolts, and the bottom surface of the right-angle reinforcement member and the support member are installed through third bolts.

[0009] Preferably, second through holes for passing through the second bolts are provided above and below the side surface of the first rail and above and below the side surface of the second rail, and a second nut is provided at the inner end of the second bolt.

[0010] Preferably, third through holes for passing through the third bolts are provided on the support member, and third nuts are provided after the third bolts pass through the third through holes.

[0011] Preferably, the right-angle reinforcement member includes a vertical plate and a horizontal plate perpendicularly connected to the vertical plate. The second bolt penetrates through the vertical plate, and the third bolt penetrates through the horizontal plate.

[0012] Preferably, a reinforcing rib plate is provided between the horizontal plate and the vertical plate.

[0013] Preferably, the female groove includes a first groove body provided on the outer side of the first rail and a second groove body provided on the inner side of the first rail. The first groove body and the second groove body are arranged at intervals along the circumferential direction of the first rail.

[0014] Preferably, the convex portion includes a first convex plate corresponding to the first groove body and a second convex plate corresponding to the second groove body. The outer side surface of the first convex plate is aligned with the outer side surface of the first rail.

[0015] According to the above technical solution, the present invention provides a ratchet structure for a walking rail of a heavy-duty shuttle car. The ratchet structure includes a hollow first rail and a hollow second rail docked with the first rail. Both the first rail and the second rail are installed on a support member through first bolts. A female groove is provided at one end of the bearing surface, bottom surface and side surface of the first rail facing the second rail, and a convex portion capable of fittingly inserting into the female groove is provided at the end of the second rail facing the second rail.

[0016] In the ratchet structure, the docking position of the first rail and the second rail is connected by the cooperation of the female groove and the convex portion. The female groove and the convex portion that are matched at the bearing surface and the bottom surface positions of the rail can play a limiting role in the horizontal direction, and the female groove and the convex portion that are matched at the side surface of the rail can play a limiting role in the vertical direction. Thus, the ratchet structure can meet the docking requirements of the walking rail of the heavy-duty shuttle car, and the flatness of the rail docking position is good, overcoming the problem that the rail connection position is prone to deviation due to the unevenness of the support member, and increasing the walking smoothness of the heavy-duty shuttle car on the rail.
