That is, in the modified embodiment, the stacker traveling mechanism 1 is driven by the two driving wheel structure, and the driven wheel structure is omitted.

As shown in fig. 2 to 4, fig. 2 is a front view of the motor drive mechanism 12 in fig. 1. Fig. 3 shows a right side view of fig. 2. Fig. 4 shows a top view of fig. 2. The motor driving mechanism 12 of the embodiment of the present invention includes a fixing frame 110, a swing arm 120, a motor driving unit 130, a buffer 140, and a rotation shaft 150. The fixing frame 110 is fixedly connected to the base 11, for example, by bolts, but not limited thereto. One end of the swing arm 120 is rotatably connected to the fixed frame 110 via a rotating shaft 150, so that the swing arm 120 can swing along the axis of the rotating shaft 150 relative to the fixed frame 110. The motor driving unit 130 is fixedly connected to the other end of the swing arm 120, for example, by a bolt, but not limited thereto. The axis of the output end of the motor driving unit 130 is parallel to the axis of the rotation shaft 150. The buffer 140 is disposed between the swing arm 120 and the rotation shaft 150.

It can be understood that the stacker belongs to large storage equipment, the power of the driving motor of the travelling mechanism is large, and the starting torque is large. When the stacker works, the driving motor needs to be started and stopped continuously because goods need to be picked and placed continuously, and the driving motor can shake back and forth.

In this embodiment, the motor driving unit 130 is fixedly connected to the swing arm 120, the swing arm 120 is rotatably connected to the fixed frame 110 through a rotating shaft 150, and the buffer 140 is disposed between the swing arm 120 and the rotating shaft 150. When the motor driving unit 130 is started, the reaction force acting on the motor driving unit 130 is transmitted to the rotating shaft 150 through the swing arm 120. Because the buffer member 140 is disposed between the swing arm 120 and the rotating shaft 150, the buffer member 140 can buffer the torsion generated by the motor driving unit 130, that is, the buffer member 140 converts the rigid force of the motor driving unit 130 into a flexible force, thereby reducing the tendency of the motor driving unit 130 to be dislocated, and avoiding the motor driving unit 130 from being abraded or damaged due to shaking when being started or stopped. Meanwhile, noise generated due to shaking of the motor driving unit 130 is also reduced.

One end of the swing arm 120 has a connection hole 121, and the connection hole 121 is disposed corresponding to the position of the through hole 113. The rotating shaft 150 is disposed through the connecting hole 121, and the buffer member 140 is disposed between a hole wall of the connecting hole 121 and an outer circumferential surface of the rotating shaft 150.

The two ends of the rotating shaft 150 are provided with stoppers 192, and the stoppers 192 are used for limiting the axial position of the swing arm 120 along the rotating shaft 150 and preventing the swing arm 120 from separating from the fixing frame 110.

It is understood that the stop 192 may be a cotter pin, but is not limited thereto.

With continued reference to fig. 5, the buffer 140 may include a first bushing 141 and a second bushing 142. The first bushing 141 is sleeved on the outer circumference of the rotating shaft 150, and a portion of the first bushing 141 is inserted into one end of the connecting hole 121 along the axial direction. The second bushing 142 is sleeved on the outer circumference of the rotating shaft 150, and a portion of the second bushing 142 is inserted into the other end of the connecting hole 121 along the axial direction.

Further, a part of the first bushing 141 is interposed between one of the supporting portions 112 and the swing arm 120, and a part of the second bushing 142 is interposed between the other supporting portion 112 and the swing arm 120.

That is, the first bushing 141 and the second bushing 142 each include two portions, one of which is disposed between the outer peripheral wall of the rotating shaft 150 and the hole wall of the connecting hole 121 of the swing arm 120, and the other of which is interposed between the support portion 112 and the swing arm 120. In this way, the first bushing 141/the second bushing 142 are disposed between the swing arm 120 and the rotating shaft 150 and between the swing arm 120 and the supporting portion 112, so that the first bushing 141/the second bushing 142 can better buffer the motor driving unit 130.
