[0026] As Figures 1 to 5 shown, Embodiment 1: A train maintenance robot facilitating cross-channel operation, comprising: an intelligent walking robot 1; two groups of symmetric main mounting blocks 6, respectively connected to the body of the intelligent walking robot 1, and two groups of symmetric main mounting blocks 6 are respectively connected to guide rods 7; four main electric push rods 5, respectively connected to the corresponding main mounting blocks 6, and the push rods of each main electric push rod 5 are respectively connected to the wheel seats of electric wheels 8; symmetric secondary mounting blocks 9, respectively connected to the corresponding guide rods 7; symmetric auxiliary electric push rods 10, respectively connected to the corresponding secondary mounting blocks 9, and the push rods of the symmetric auxiliary electric push rods 10 are respectively connected to the wheel seats of auxiliary wheels 11. By adopting the main electric push rods 5 and the auxiliary electric push rods 10, it is convenient to realize the step movement of the device along the channel.
[0027] The front and rear ends of the intelligent walking robot 1 are respectively connected to a ranging sensor group 2. It includes at least one laser ranging sensor that is vertically downward, two that are perpendicular to the length direction of the intelligent walking robot 1, and one that is parallel to the length direction, to measure the distance to steps and obstacles, assist the robot in moving along the steps, and achieve cross-channel operation.
[0028] The model of the laser ranging sensor is GJD-06.
[0029] An antenna 4 is installed at the rear of the intelligent walking robot 1.
[0030] A controller is installed inside the intelligent walking robot 1. The ranging sensor group 2, antenna 4, main electric push rod 5, electric wheel 8, and auxiliary electric push rod 10 are respectively electrically connected to the controller. The controller is wirelessly connected to a host computer. The host computer includes but is not limited to a computer, PC, tablet, mobile phone, and liquid crystal display, etc.
[0031] The model of the controller is STM32WB55CGU6.
[0032] The models of the main electric push rod 5 and the auxiliary electric push rod 10 are BMXL.
[0033] The working process of this embodiment is as follows:
[0034] The position, width, and height of the steps are measured by the ranging sensor group 2.
[0035] Before going upstairs, control the main electric push rod 5 and the auxiliary electric push rod 10 to fully extend, so that the electric wheel 8 and the auxiliary wheel 11 contact the ground, raise the intelligent walking robot 1, control the electric wheel 8 to work, and move this device forward. When the intelligent walking robot 1 approaches the steps, control the front main electric push rod 5 to contract, so that the front electric wheel 8 is flush with the upper step surface. After the front electric wheel 8 contacts the upper step surface, control the auxiliary electric push rod 10 to contract, so that the auxiliary wheel 11 is flush with the upper step surface. When the rear electric wheel 8 approaches the vertical surface of the upper step, control the rear main electric push rod 5 to contract, so that the rear electric wheel 8 is flush with the upper step surface. Repeat this process to achieve climbing the stairs.
[0036] When going downstairs, control the main electric push rod 5 and the auxiliary electric push rod 10 to extend halfway, so that the intelligent walking robot 1 is away from the step surface. After the front electric wheel 8 leaves the step surface, control the front main electric push rod 5 to extend, so that the front electric wheel 8 contacts the plane of the lower step, and so on, to achieve going downstairs.
[0037] Embodiment 2: This embodiment further elaborates on the basis of Embodiment 1. The symmetric guide rods 7 respectively pass through the symmetric first vertical rods 16, and each first vertical rod 16 is respectively connected to a downstairs counterweight 15. By setting the downstairs counterweight 15, when this device goes down the steps, the center of gravity moves backward to prevent this device from tipping forward.
[0038] Each of the guide rods 7 is rotatably connected to the centers of two upper connecting rods 14. Each of the upper connecting rods 14 is respectively connected to a first circular block 18. Each of the first vertical rods 16 is respectively provided with a lower vertical groove 17. Each of the first circular blocks 18 is respectively arranged in the corresponding lower vertical groove 17.

Each of the second circular blocks 19 is respectively arranged in the corresponding upper vertical groove 13. By adopting the lower connecting rod 3 to rotatably connect the wheel seat of the electric wheel 8 and the second vertical rod 12, and arranging the second circular block 19 in the upper vertical groove 13, when the electric wheel 8 moves in the height direction, the downstairs counterweight 15 moves. When going downstairs, as Figure 5 shown, the rear downstairs counterweight 15 moves backward, shifting the center of gravity of the robot backward, making it more stable when going down the steps.
[0040] The working process of this embodiment is as follows:
[0041] When the electric wheel 8 moves in the height direction, it drives the lower connecting rod 3 to swing. The lower connecting rod 3 drives the second vertical rod 12 to move along the guide rod 7. The second vertical rod 12 drives the second circular block 19 to move along the upper vertical groove 13. The second circular block 19 drives the upper connecting rod 14 to swing. The upper connecting rod 14 drives the first circular block 18 to move in the lower vertical groove 17. The first circular block 18 drives the first vertical rod 16 to move along the guide rod 7. The first vertical rod 16 drives the downstairs counterweight 15 to move.
