[0017] like Figure 1 、 Figure 2 The walking drive structure shown in the figure comprises a moving trolley, which comprises two symmetrically arranged trolley connecting plates 1, and a driving wheel set 2 and a brake set are provided on the moving trolley. Figure 3 As shown, the driving wheel group 2 includes a driving wheel 22, a motor 23 and a clutch cylinder 29. The driving wheel 22 is arranged between the two driving side plates 21, and the motor 23 is connected to the driving side plate 21 on one side. The motor 23 is connected to the driving wheel 22 through a driving shaft, and the bottom ends of the driving side plates 21 on both sides are connected to each other through a first support beam 25. The two ends of the first support beam 25 are connected to the trolley connecting plates 1 on both sides. A clutch cylinder 29 is set at the other end of the driving side plate 21, and the piston rod of the clutch cylinder 29 is connected to the center of the second support beam 27. The two ends of the second support beam 27 are connected to the trolley connecting plates 21 on both sides.

[0018] The moving trolley is set on the track. When the moving trolley drives the unpacking machine to move, the motor 23 rotates the driving wheel 22 to drive the unpacking machine to move. When the clutch cylinder 29 is started, the driving vehicle plate rotates around the first support beam 25, the driving wheel 22 leaves the track, the moving trolley loses power, and the brake group is started to stop the moving trolley. In this way, the parking position of the trolley can be accurately controlled.

[0019] The brake assembly includes a cylinder mounting base 3, which is positioned between the two trolley connecting plates 1. One or more brake cylinders 5 are mounted at the bottom of the cylinder mounting base 3. These brake cylinders 5 are diaphragm-type clamping cylinders with diaphragms mounted at their bottoms. When the brake cylinders 5 are activated, the diaphragms pop out, and friction between the diaphragms and the track causes the trolley to stop.

[0020] The drive wheel 22 is provided with a support plate 24 at the front and rear, respectively. The support plates 24 connect the drive side plates 21 on either side. One of the support plates 24 is connected to the clutch cylinder 29 via a bracket 26. The support plates 24 protect the front and rear of the drive wheel 22, preventing the drive shaft from deforming and jamming due to collisions, while also strengthening the support force of the drive wheel 22. The support plates 24 are provided with multiple connection holes to facilitate the connection of other equipment.

[0021] A triangular bracket 28 is arranged between the piston rod of the clutch cylinder 29 and the second support beam 27. The triangular bracket is a trough structure, and the second support beam 27 is arranged in the trough and is connected by a snap structure or other connecting structure. The triangular bracket 28 can rotate around the second support beam 27. The two sides of the triangular bracket are isosceles triangle plates, and the piston rod is connected to the top center of the isosceles triangle plate through a connecting shaft. When the clutch cylinder 29 pushes, the second support beam 27 can be evenly stressed to avoid deformation.

[0022] The two ends of the inner side of the trolley connecting plate 1 are respectively provided with connecting pads 4. The trolley connecting plate 1 clamps both sides of the track. The connecting pads 4 fill the gap between the trolley connecting plate 1 and the track to prevent the moving trolley from shaking and ensure the stability of the movement.

[0023] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
