Specifically, the substitute wheel fixing seat 52 is a U-shaped seat, and the inner surface of the U-shaped seat is attached to the sliding table 41 of the linear sliding mechanism 4, so that the linear sliding mechanism 4 can slide with the substitute wheel conversion mechanism 5.
As a further explanation of the embodiment of the present invention, the linear slide mechanism 4 includes a slide table 41 that is slidable in place of the wheel changing mechanism 5.
As a further description of the embodiment of the present invention, in the embodiment, an additional linear sliding driving element is not disposed on the sliding table 41, and the linear sliding driving element and the wheel driving motor 22 can be integrated into one by directly using the travel failure multiplexing motor unit.
Specifically, the linear sliding driving element according to the present embodiment is a driving element that drives the substitute wheel fixing seat 52 of the substitute wheel changing mechanism 5 to move. Specifically, the linear sliding driving piece can be composed of linear driving devices such as a linear motor, a push rod motor and a cylinder, the wheel replacing mechanism 5 is installed on the sliding table 41, the sliding table 41 is fixedly installed on the vehicle body chassis 1, and the linear sliding driving piece is connected with the wheel replacing mechanism 5.

Specifically, when the wheel assembly 2 is not damaged, the electromagnetic bolt 72 acts on the hinged plate 38 to limit the hinged plate 38, so that the first winding turnover mechanism 8 and the second winding turnover mechanism 9 cannot drive the wheel 21 to move in the moving process of the wheel 21, and the safety of the whole robot is ensured.
Since the wheel 21 of the replacement-wheel exchanging mechanism 5 is a universal wheel, no malfunction generally occurs with respect to the other four wheels 21. In practice, the wheel type robot only has one wheel 21 fault, and the faults of more than two wheels 21 can not occur, so that the wheel type robot of the invention can meet the wheel 21 fault under most conditions.
In addition, the mode can ensure that the wheel 21 on one side has a fault once, so theoretically, under the condition that other parts and systems of the wheeled robot have no faults, the service life of the wheel assembly 2 of the wheeled robot can be ensured to be twice as long as the original service life.
As a further preferable mode for the embodiment of the present invention, the universal wheel of the alternative wheel exchanging mechanism 5 may be designed such that the center of the universal wheel is higher than the centers of the front and rear wheels, so that the two alternative wheels 21 are first turned downward in the process of the linear sliding mechanism driving the universal wheel to slide to the side of the failed wheel 21, and the two alternative wheels 21 that are turned may temporarily not land due to the fact that the centers of the universal wheels are higher than the centers of the front and rear wheels, so that the requirement for the driving force of the linear sliding mechanism may be reduced, and when the linear sliding mechanism driving the universal wheel to approach the side of the failed wheel 21, the two normal alternative wheels 21 land. Similarly, because the center of the universal wheel is higher than the centers of the front wheel and the rear wheel, the two failed wheels 21 can be lifted off the ground in an overhead manner, then the linear sliding mechanism drives the universal wheel to continuously slide to one side of the failed wheel for a certain distance, so that the two failed wheels 21 which do not touch the ground (are lifted off by the universal wheel) are turned upwards, and at the moment, the universal wheel and the two replaced normal wheels 21 which are turned over form a two-wheel differential three-wheel driving system.
In short, the two failed wheels 21 are suspended by the universal wheels and then turned over, and the demand for the driving force of the linear sliding mechanism can be reduced. The requirement for the driving force of the linear sliding mechanism can also be reduced by making the two alternative normal wheels 21 overhead by the universal wheels and then turning them over.
The working principle of the embodiment of the invention is as follows: assuming that the substitute wheel switching mechanism 5 is disposed at the front side or the rear side of the sliding table 41, for convenience of description, assuming that the substitute wheel switching mechanism 5 is disposed at the front side of the sliding table 41, the wheel assembly 2 located at the front side is folded and turned upwards, the wheel assembly 2 at the rear side and the substitute wheel switching mechanism 5 together drive the wheeled robot to travel, and the cart is driven to move by two steering motors and driving motors of the rear wheels. In addition, the universal wheel is in a preferred use mode that the center of the front wheel is higher than that of the rear wheel, when no fault occurs at ordinary times, the hinged plate 38 can be limited through the electromagnetic bolt 72, and it is guaranteed that the first winding turnover mechanism 8 and the second winding turnover mechanism 9 cannot drive the wheel 21 to rotate and turn over the wheel 21 in the moving process of the wheel 21, namely the hinged plate 38 cannot drive the wheel 21 to move, and the safety of the whole robot is guaranteed. When one wheel 21 on the rear side fails or 2 wheels 21 fail together, the first winding-and-folding mechanism 8 and the second winding-and-folding mechanism 9 drive the substitute wheel fixing seat 52 and the substitute wheel 51 to move to the rear side of the vehicle body chassis 1. Specifically, the winch and the wheel axle 23 are connected through the first clutch 88 and the second clutch 92, and at this time, the wheel driving motor 22 drives the wheel axle 23 to rotate and simultaneously drives the first winch 84 and the second winch 94 to work together, and the substitute wheel switching mechanism 5 is pulled to slide on the sliding table 41 under the connecting action of the first wire winding assembly 82, the second wire winding assembly 83 and the third wire winding assembly 93, so that the substitute wheel switching mechanism 5 moves to one side of the rear failed wheel 21 under the action of the sliding table 41, and simultaneously, the front normal wheel assembly 2 is folded and turned over to the lower side, and the rear failed wheel assembly 2 is folded and turned over to the upper side, thereby forming the three-wheel mechanism of the front two-wheel and rear substitute wheel switching mechanism 5. And finally, the main control system controls a normal wheel driving motor 22 to drive two rear wheels 21 to move, the substitute wheel conversion mechanism 5 and the normal two wheels 21 form a three-wheel differential driving system, and the substitute wheel conversion mechanism 5 and the normal wheels 21 drive the wheel type robot to walk together. Therefore, the problem of inconvenience in maintaining the robot in severe environments such as a transformer substation and the like can be solved, the service life of a walking system of the robot can be prolonged, and the reliability of the robot can be improved.
