The road roller has the advantages that the gear shaft drives the gear ring to rotate, the traction rope is wound and unwound by the winding roller, the traction rope extends out of or penetrates into the limiting groove, traction force on the road roller is kept in the same direction, and meanwhile, due to the fact that the winding roller is arranged on the first rotating shaft in a sliding mode, in the meshing movement process of the gear ring and the gear shaft, the traction force on the road roller is kept in the same direction. The winding roller can move in the axial direction, and the traction rope can be evenly wound around the winding roller conveniently.

Description

Technical Field

[0001] The utility model relates to the technical field of traction devices, in particular to a traction device for a road roller. Background Art

[0002] When a steel-wheel roller is driven onto a flatbed transport vehicle via a ladder, it may slip, making it difficult to drive onto the flatbed transport vehicle and posing a risk of slipping. The prior art uses a hydraulic winch to drive a steel cable and a hook to provide traction assistance to the roller, thereby ensuring that assistance can be provided during the process of the steel-wheel roller being driven onto the flatbed transport vehicle trailer via a ladder. However, the winch cannot move in the axial direction when the steel cable is retracted or released.

[0003] When the roller is towed, the steel cable is reeled in. Since the winch cannot move axially, the steel cable will be concentrated and wound on the same position of the outer wall of the winch. The stacking is relatively disordered and cannot be evenly spread along the cylindrical outer wall of the winch. The disordered stacking can easily cause the outer circle of the steel cable to slide to one side, causing the roller to shake momentarily and impact the flatbed transport vehicle, which can easily increase the wear of the transport vehicle. At the same time, when the roller is released, the steel cable cannot be unwound in the same straight line, which produces traction forces in different directions on the roller, which can easily cause the roller to deflect and reduce the stability of the roller during the release process.

[0004] In order to solve the above problems, we propose a road roller traction device. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 4A roller traction device comprises a bottom plate 1, a plurality of mounting holes 21 are provided on the bottom plate 1, and the bottom plate 1 is convenient for fixing the bottom plate 1 on the frame of a flatbed transport vehicle. Two vertically upwardly arranged support plates 1 2 and 2 3 are fixedly connected to the bottom plate 1, and the support plates 1 2 and 2 3 are parallel to each other. A reinforcing plate is provided between the outer walls of the support plates 1 2 and 2 3 and the upper wall of the bottom plate 1, and the outer walls of the support plates 1 2 and 2 3 are provided with a through-port 1 4 near the upper end thereof, and a bearing 1 5 is fixedly provided in the through-port 1 4, and a rotating shaft 1 6 is fixedly inserted between the two bearings 1 5, and the outer wall sliding sleeve of the rotating shaft 1 6 is provided with a shaft sleeve 7 located between the support plates 1 2 and 2 3, and the outer wall of the shaft sleeve 7 A winding roller is fixedly provided on the fixed sleeve, and a traction rope 8 is wound around the winding roller. Baffles 9 are fixedly provided at both ends of the winding roller. The baffle 9 is arranged in a ring shape, and a gear ring 10 is fixedly provided on the outer edge of the baffle 9. The outer walls of the support plate 1 2 and the support plate 2 3 are provided with a through-port 11 located at the lower side of the corresponding through-port 1 4. A bearing 2 is fixedly provided in the through-port 11, and a rotating shaft 2 12 is fixedly inserted between the two bearings 2. The outer wall of the rotating shaft 2 12 is fixedly provided with a gear shaft 13 located between the support plate 1 2 and the support plate 2 3. The two ends of the gear shaft 13 are respectively close to the support plate 1 2 and the support plate 2 3. The gear shaft 13 is meshed with the gear ring 10, and the outer walls of the gear teeth on the gear shaft 13 and the gear ring 10 are smoothly arranged.

[0021] A belt roller 14 located on the outside of the support plate 2 is fixedly provided at the end of the rotating shaft 12, and a driving mechanism is provided on the left side of the support plate 2. The driving mechanism includes an angle plate 17 fixed on the base plate 1, and a motor 18 located on the upper side of the base plate 1 is fixedly provided on the rear side wall of the angle plate 17. A belt roller 19 located on one side of the belt roller 14 is fixedly provided at the driving end of the motor 18. A belt 20 is commonly sleeved between the belt roller 19 and the belt roller 14. After the motor 18 is started, the belt roller 19 drives the belt roller 14 to rotate through the belt 20. At the same time, the rotating shaft 12 drives the gear shaft 13 to rotate. Under the meshing action of the gear shaft 13 and the gear ring 10, the roller will rotate to realize the winding and unwinding of the traction rope 8. A controller 22 located on one side of the motor 18 is provided on the angle plate 17, and a plurality of buttons are provided on the controller 22 for controlling the forward and reverse rotation and start and stop of the motor 18.

[0022] A limit plate 15 located at the front side of the winding roller is fixedly arranged on the bottom plate 1. The limit plate 15 is arranged vertically upward. Vertical plates are fixedly arranged on both sides of the limit plate 15. The vertical plates are fixedly connected to the bottom plate 1. The vertical plates improve the stability of the limit plate 15. A vertical limit groove 16 is opened on the limit plate 15. The end of the traction rope 8 passes through the limit groove 16. After the traction rope 8 passes through the limit groove 16, the traction force on the roller will be maintained in the same direction, and the roller will not be deflected when being towed, thereby improving the stability of the roller during traction.

[0023] When the roller is towed onto the flatbed transport vehicle, the traction rope 8 is gradually wound around the winding roller. When the traction rope 8 touches the outer wall of the traction rope 8 that has been wound around the winding roller, an extrusion force will be generated. Since the winding roller is slidably mounted on the rotating shaft 6 through the shaft sleeve 7, and the outer walls of the gear teeth on the gear shaft 13 and the gear ring 10 are both smoothly arranged, during the rotation of the winding roller, the extrusion force between the traction ropes 8 will drive the winding roller to move along the axial direction, so that the traction rope 8 is evenly wound along the outer wall of the winding roller and stacked layer by layer. The same is true when the roller is released from the flatbed vehicle. The pulling force of the traction rope 8 on the winding roller will drive the winding roller to move along the axial direction, reducing the force on the limit plate 15, so that the traction rope 8 can be stably wound or unwound, avoiding the sudden slip of the traction rope 8 and causing the roller to shake.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
