The bearing wheels 150 are used to run on the upper surface of the rail 200. Specifically, the load-bearing wheels 150 are used to carry the entire rail transport draft gear 100. The driving wheel 160 is connected to the bearing wheel 150, and specifically, the driving wheel 160 and the bearing wheel 150 are both rotatably connected to the frame 130, and the driving wheel 160 and the bearing wheel 150 are connected through the frame 130. The drive wheel 160 is used for gear transmission to the rail 200. Specifically, the driving wheel 160 is provided with a gear shape, the rail 200 is provided with a rack 210, the driving wheel 160 is meshed with the rack 210 on the rail 200, and the rack 210 is arranged on the lower surface of the rail 200 to prevent the rack 210 from influencing the walking of the bearing wheel 150, so that the driving wheel 160 can not be tightly attached to the rail 200 under the action of gravity, the friction force between the driving wheel 160 and the rail 200 can be effectively reduced, and the energy utilization rate is improved. Of course, in some embodiments of the present application, the rack 210 may be disposed on the side of the track 200, as long as the gear and the rack 210 can be engaged and not tightly fit.

Specifically, the braking mechanism 110 is a limiting mechanism, and the driving mechanism 120 stops rotating under the action of the braking mechanism 110. In some embodiments of the present application, the braking mechanism 110 may be an electromagnetic brake, and the driving mechanism 120 may be a motor, and the electromagnetic brake may control the motor to stop rotating, so as to control the driving wheel 160 to stop rotating, so as to stop the rotation of the bearing wheel 150.
Therefore, the rail transportation traction mechanism 100 can move the driving wheel 160 relative to the rail 200 by the rolling of the driving wheel 160, thereby driving the bearing wheel 150 to run along the upper surface of the rail 200, during the process of the bearing wheels 150 walking along the surface of the rail 200, if the rail transport traction mechanism 100 is required to stop at the current position, the braking mechanism 110 is only required to control the driving mechanism 120 to brake, the rotation of the driving wheel 160 can be stopped, and due to the gear transmission between the driving wheel 160 and the rail 200, therefore, after the rotation of the driving wheel 160 is stopped, the position of the driving wheel 160 relative to the rail 200 is kept unchanged, the bearing wheel 150 cannot continue to run under the action of inertia, the rail transport traction mechanism 100 can be parked at any position of the rail 200, and the rail transport vehicle with the rail transport traction mechanism 100 can also be parked at any position of the rail 200.

Specifically, the driving wheel 160 has a second transmission part 163, that is, another rotating disc is fixedly connected to the driving wheel 160, and the driving wheel 160 can be driven to rotate by the driving mechanism 120 by connecting the first driving part 121 and the second driving part 163 through a chain or a belt. Of course, in other embodiments of the present application, the driving mechanism 120 may also drive the driving wheel 160 to rotate through a gear or a transmission rod to achieve the power output.
In some embodiments of the present application, the load-bearing wheels 150 are provided in two, and the two load-bearing wheels 150 are spaced apart in the advancing direction of the driving wheel 160. The walking stability of the whole rail transport traction mechanism 100 can be effectively improved by using the two bearing wheels 150. Of course, in other embodiments of the present application, the bearing wheels 150 may be provided in any number, such as three, four, etc., as long as they can bear the weight of the entire rail transport traction mechanism 100 and can walk on the surface of the rail 200.

During use, portions of the pins 161 may be replaced depending on the particular damage to each pin 161. And the pin 161 and the driving disc 162 can be connected in a rotating manner, so that the different positions of the pin 161 can be stressed uniformly in the rotating process relative to the rack 210, the repeated abrasion of the same position of the pin 161 is avoided, and the service life of the pin 161 is prolonged.
Of course, in other embodiments of the present application, the driving wheel 160 may be configured as an integral structure to reduce the cost, and it is only necessary that the driving wheel 160 is engaged with the rack 210 and can push the bearing wheel 150 to move during the rotation process.
In some embodiments of the present application, the rail transportation traction mechanism 100 further includes an adjusting structure 140, the adjusting structure is used for adjusting the driving wheel 160 to approach or depart from the rail 200 in the vertical direction, that is, the adjusting structure 140 is used for adjusting the distance between the driving wheel 160 and the rail 200, and the driving wheel 160 can be conveniently adjusted to be meshed with the rack 210 by using the adjusting structure 140, so as to push the bearing wheel 150 to walk in the rotating process without being closely attached to the rack 210, thereby ensuring the transmission efficiency.

In the process that the telescopic member 141 drives the lever 142 to rotate, the position of the bearing wheel 150 in the vertical direction also changes, and specifically, under the action of the lever 142, the bearing wheel 150 descends in the process that the telescopic member 141 drives the other end of the lever 142 to ascend; during the process that the telescopic member 141 drives the other end of the lever 142 to descend, the bearing wheel 150 ascends. And since the rack 210 is arranged on the lower surface of the track 200, the driving wheel 160 is arranged below the track 200, so that the bearing wheel 150 is controlled to ascend relative to the frame 130, that is, the frame 130 is controlled to descend relative to the track 200, that is, the driving wheel 160 is controlled to descend relative to the track 200, that is, the distance between the driving wheel 160 and the rack 210 is controlled to increase, so as to control the distance between the driving wheel 160 and the rack 210, and to facilitate the driving wheel 160 to be adjusted to be meshed with the rack 210 but not tightly attached.
Specifically, in some embodiments of the present disclosure, the retractable member 141 may be a screw, and since the bearing wheel 150 bears the weight of the whole rail transportation traction mechanism 100, under the action of gravity, the bearing wheel 150 will be closely attached to the upper surface of the rail 200, that is, under the action of gravity, the bearing wheel 150 will exert an upward force on one end of the lever 142, and at this time, only the same force is required to be exerted on the other end of the lever 142, so as to maintain the balance of the forces at the two ends of the lever 142. Specifically, the rack 130 is provided with a threaded hole, the screw rod is screwed into the threaded hole, and the end of the screw rod abuts against the other end of the lever 142, so that the screw rod can be used for applying a supporting force to the other end of the lever 142 to balance the stress at the two ends of the lever 142, and when the height of the other end of the lever 142 needs to be adjusted, only the screw rod needs to be screwed.

Specifically, the guide wheel 170 is clamped on the rail 200, and in the process that the guide wheel 170 rotates relative to the rail 200, the surface where the rotation direction of the guide wheel 170 is located is always parallel to the tangent of the current rail 200, so that when the rail 200 turns, the guide wheel 170 also rotates correspondingly, and the bearing wheel 150 is driven to rotate.
Specifically, the guide wheel 170 may include a guide plate 171 and a flange 172, the guide wheel 170 is for rolling transmission to the rail 200, and the flange 172 is for clamping the rail 200. By using the guiding disc 171 in rolling transmission with the track 200, it can be ensured that the guiding wheel 170 can follow the turning direction of the track 200 in time only by means of rolling transmission, and the flange 172 can further improve the guiding effect of the guiding wheel 170. Of course, in other embodiments of the present application, the guiding disc 171 may not contact the rail 200, and only the flange 172 may be used to clamp the rail 200.
