[0023] The driving structure 15 can be a common driving motor in the prior art.

[0024] The supporting structure includes a supporting frame 16 movably connected to the base plate 2, and the bottom end of the supporting frame 16 is movably connected to a supporting wheel 23. An electromagnet 22 is fixed to one side of the bottom end of the supporting frame 16. The electromagnet 22 and the supporting wheel 23 are in a state of movably connection. However, when the electromagnet 22 is in a powered-on state, the electromagnet 22 and the supporting wheel 23 are in a state of magnetic attraction, fixing the position of the supporting wheel 23. In some embodiments of the present application, a ferromagnetic metal, such as metallic iron, is fixed to the contact portion between the supporting wheel 23 and the electromagnet 22.

[0025] Another electromagnet 22 is fixedly connected to the top of the support frame 16, and the other electromagnet 22 is movably connected to the bottom plate 2. When the other electromagnet 22 is powered on, the other electromagnet 22 and the bottom plate 2 are magnetically attracted to each other to fix the position of the support frame 16. In some embodiments of the present application, a ferromagnetic metal, such as metallic iron, is fixed to the part where the bottom plate 2 contacts the other electromagnet 22.

[0026] There are at least two of the above-mentioned shape structures and support structures, and when the trolley is moving, the bottoms of the walking structure and the support structure are at the same height, the walking structure and the support structure can support the trolley at the same time, and the walking structure controls the moving direction of the trolley, but when the hydraulic telescopic rod 17 is in a retracted state, the bottom of the walking wheel 3 can be separated from the ground, and the support structure supports the trolley at this time.

[0027] The two adjacent walking structures are connected by a synchronous structure, which includes a synchronous sprocket 20 fixedly connected to the outer ring of the hydraulic telescopic rod 17 and a hydraulic telescopic rod 2 18 fixedly connected to the top of the bottom plate 2.

[0029] A first workbench 4 is provided on both sides of the frame 1, and a translation plate 5 is provided on the top of the first workbench 4.

The outer ring of the ball screw 12 is threadedly connected to a ball nut 1, and the ball nut 1 is fixedly connected to the translation block 11. Through the setting of the servo motor 13, the rotation of the servo motor 13 can drive the ball screw 12 to rotate, and the rotation of the ball screw 12 can make the ball nut 1 threadedly connected thereto move in the direction of the ball screw 12. When the ball nut 1 moves, it can drive the translation block 11 fixedly connected thereto to move, and the translation block 11 drives the translation plate 5 fixedly connected thereto to move, that is, the rotation of the servo motor 13 can change the position of the translation plate 5.

[0030] A second workbench 6 is fixed on the top of the vehicle frame 1, and a translation plate 2 7 is connected to the top of the second workbench 6 through a translation structure 2. In some embodiments of the present application, the translation structure 2 includes a ball screw 2 9 movably connected to the second workbench 6, a ball nut 2 threadedly connected to the ball screw 2 9, a translation block 2 10 fixedly connected to the ball nut 2, and a servo motor 2 8 fixedly connected to the second workbench 6. The end of the output shaft of the servo motor 2 8 is connected to the end of the ball screw 2 9 through a reducer, and the translation block 2 10 is fixedly connected to the translation plate 2 7. Through the setting of the servo motor 2 8, the rotation of the servo motor 2 8 can drive the ball screw 2 9 connected thereto to rotate, and when the ball screw 2 9 rotates, the ball nut 2 threadedly connected thereto can move in the direction where the ball screw 2 9 is located, and when the ball nut 2 moves, it can drive the translation block 2 10 fixedly connected thereto to move, and the translation block 2 10 drives the translation plate 2 7 fixedly connected thereto to move, that is, under the action of the servo motor 2 8, the position of the translation block 2 10 can change.

The buffer pad can reduce the mutual influence between the second translation plate 7 and the second workbench 6, making it easier to use the trolley. The buffer pad can be made of rubber.

[0032] From the above description, it can be seen that when the trolley is in use, lateral and longitudinal movement can be achieved through the walking structure, the positions of both the translation plate 1 5 and the translation plate 2 7 can be moved, and the positions of the devices fixed on the translation plate 1 5 or the translation plate 2 7 can be fine-tuned to facilitate the use of the trolley.

[0033] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0034] To sum up: when the walking tunnel trolley is in use, the walking wheel 3 and the supporting wheel 23 are at the same height and are in contact with the tunnel ground. The operation of the driving structure 15 can drive the walking wheel 3 to rotate. When the walking wheel 3 rotates, the trolley can be driven to move in the tunnel along the direction of the walking wheel 3. When the walking wheel 3 and the bottom plate 2 are in a horizontal state, the trolley can realize longitudinal movement in the tunnel. When the walking wheel 3 and the bottom plate 2 are in a vertical state, the trolley can realize lateral movement in the tunnel. When the trolley is in use, the position of the walking wheel 3 can be changed through the synchronous structure. When the position of the walking wheel 3 needs to be changed, the hydraulic telescopic rod 17 is retracted until the hydraulic telescopic rod The hydraulic telescopic rod 17 drives the running wheel 3 to separate from the ground. At this time, the trolley is supported by the supporting structure. The electromagnet 22 is energized. The electromagnet 22 and the supporting wheel 23 or the bottom plate 2 in contact with it are magnetically attracted to each other, and the position of the supporting structure is fixed, so that the position of the trolley can remain unchanged. The hydraulic telescopic rod 18 is extended and retracted. The extension and retraction of the hydraulic telescopic rod 18 can change the movement of the connecting block 19 fixedly connected to it. When the connecting block 19 moves, it can drive the synchronous chain 21 fixedly connected to it to move. The synchronous chain 21 drives the hydraulic telescopic rod 17 to rotate through the synchronous sprocket 20 meshing with it. The hydraulic telescopic rod 17 drives the running wheel 3 to rotate, and the position of the running wheel 3 changes. During the use of the trolley, the positions of both the translation plate 15 and the translation plate 27 can be adjusted, so that the position of the device fixed on the translation plate 27 or the translation plate 15 can be fine-tuned, reducing the movement frequency of the trolley and facilitating the use of the trolley.
