Description

Technical Field

[0001] This utility model relates to the field of multi-layer shuttle technology, and in particular to a walking drive mechanism suitable for a material bin storage and retrieval shuttle. Background Technology

[0002] In the field of multi-level shuttle cars in automated warehouses, the shuttle car's running mechanism often uses a drive motor assembly mounted close to a single-sided bearing housing. In order to install transmission components such as motors, reducers, and bearing housings, a separate mounting base is often required. The mounting base is connected to the shuttle car's load-bearing beam, resulting in a complex structure, difficulty in tightening the motor's synchronous belt, large space occupation, and a relatively large overall weight, which directly affects the cost and operating efficiency of the shuttle car. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-layer shuttle vehicle driving mechanism with a simple overall structure, small footprint, and significantly reduced weight. To achieve the above technical objectives, the technical solution adopted in this utility model embodiment is as follows:

[0031] like Figure 1 As shown in the figure, the multi-layer shuttle car driving mechanism proposed in this embodiment includes a drive motor assembly 1, a transmission walking assembly 2, an outer fork plate assembly 3, a bearing seat 4, a guide wheel 5, and a transmission belt 6.

[0032] The outer fork plate assembly 3 is provided with bearing seats 4 at least at both ends of the first side; the transmission and travel assembly 2 is installed on the first side of the outer fork plate assembly 3 via the bearing seats 4 at least at both ends of the first side of the outer fork plate assembly 3; the drive motor assembly 1 is installed on the first side of the outer fork plate assembly 3 near the middle position and is connected to the transmission and travel assembly 2 via a transmission belt 6.

[0033] A guide wheel 5 is installed at one end of the outer fork plate assembly 3.

[0034] More preferably, the transmission and travel assembly 2 is also mounted on the first side of the outer fork assembly 3 via a bearing seat 4 located in the middle of the outer fork assembly 3.

[0035] This application fixes the drive motor assembly 1 and the transmission and travel assembly 2 to the side of the outer fork plate assembly, eliminating the need for a separate mounting base. The overall structure is simple, the layout occupies little space, and the weight can be reduced.

[0036] like Figure 2As shown, the transmission and walking assembly 2 includes a first transmission shaft 201, a coupling 202, a second transmission shaft 203, a driven pulley 204, and a walking wheel 205;

[0037] The first drive shaft 201 and the second drive shaft 203 are connected by a coupling 202. The driven pulley 204 is mounted on the second drive shaft 203 near the end of the coupling 202. The end of the first drive shaft 201 away from the coupling 202 passes through a bearing seat 4 and is connected to a wheel 205. The end of the second drive shaft 203 near the coupling 202 passes through a bearing seat 4, and the end of the second drive shaft 203 away from the coupling 202 passes through a bearing seat 4 and is connected to a wheel 205.

[0038] This application splits the drive shaft into two half-shafts, connected by a coupling, and adds an auxiliary bearing seat for support in the middle of the transmission and walking assembly 2. This improves the overall rigidity of the transmission mechanism and facilitates processing and installation. The walking wheels are installed close to the bearing seat, which effectively shortens the support lever arm, reduces the bending moment of the drive shaft, and makes lightweight design of the whole machine possible.

[0039] Furthermore, the rotation plane of the walking wheel 205 is perpendicular to the rotation plane of the guide wheel 5 and is also perpendicular to the first side surface of the outer fork plate assembly 3.

The drive motor assembly 1 is connected to the bent part of the flange base 104 by bolts passing through the fixing plate 304, the elongated hole 306 in the adjustment groove 305 and the pad plate 105, so as to connect the drive motor assembly 1 to the outer fork plate 301.

[0045] Threaded holes are provided above and below the adjustment groove 305 on the first side of the outer fork plate 301, and an adjustment screw 302 is provided in the threaded hole, and a locking nut 303 is provided on the adjustment screw 302.

[0046] By adjusting the adjusting screws 302 above or below the adjusting groove 305 on the first side of the outer fork plate 301, the pad 105 can be moved in the adjusting groove 305 on the first side of the outer fork plate 301, thereby moving the entire drive motor assembly 1 and tightening the transmission belt 6; after the transmission belt 6 is tightened, the locking nut 303 is tightened.
