Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to make the description of the present disclosure more complete and complete, the following description is given for illustrative purposes with respect to the embodiments and examples of the present invention; it is not intended to be the only form in which the embodiments of the invention may be practiced or utilized. The embodiments are intended to cover the features of the various embodiments as well as the method steps and sequences for constructing and operating the embodiments. However, other embodiments may be utilized to achieve the same or equivalent functions and step sequences.

Example 1:

the utility model provides a rail running gear, includes mount 10, driving motor 1, differential mechanism 2, walking drive wheel 4, walking from driving wheel 5, driving motor 1 connects differential mechanism 2, differential mechanism 2 sets up on the mount 10, differential mechanism 2's one end is provided with the runner, the runner pass through the conveyer belt 3 with walking drive wheel 4 connects, the walking is from driven spindle of driving wheel 5 connection, driven shaft support piece is connected in driven spindle, driven shaft support piece fixes on the mount 10. The walking driven wheels 5 are used for balancing the center of gravity.

Specifically, the traveling driving wheel 4 has a dual driving structure. The walking driving wheel 4 comprises a circular roller 8 and a hobbing roller 9, and the circular roller 8 is coaxially connected with the hobbing roller 9. The diameter of the hobbing roller 9 is smaller than the diameter of the round roller 8. The circular roller 8 is used for the straight track section 6; the hobbing roller 9 is used for climbing the track section 7. The hobbing roller 9 is meshed with the rack of the climbing track section 7.

When the straight track section 6 walks, the round roller 8 plays a main driving role, and the outer diameter of the hobbing roller 9 is smaller than that of the round roller 8, so the hobbing roller 9 does not contact the straight track section 6, and normal running is not influenced. When the track traveling mechanism moves to the climbing track section 7, the hobbing of the hobbing roller 9 is meshed with the rack arranged on the track, the gear-rack meshing force is used as the driving friction force, and the track traveling mechanism is driven to pass through the climbing track section 7.

The track running mechanism solves the problem of slipping caused by insufficient friction force when climbing a track with a larger slope, has a simple and convenient structure, does not need to prepare in advance in a climbing track section 7, and automatically engages for transmission.
