In order to increase the stability of the car body 1, the stabilizer bar 13 and the crossbeam 2 are arranged at the bottom of the car body 1 at the other end. A cavity is opened at the bottom of the column 3, and a walking mechanism 4 for moving the new energy tunnel construction integrated trolley is arranged in the cavity. The two walking mechanisms 4 on the same side are provided with the same matching track 14 at the bottom. The cooperation between the walking mechanism 4 and the track 14 facilitates the movement of the car body 1. The track 14 is fixedly installed on the ground, and a walking mechanism for people to walk is fixedly installed on the car body 1. Plate 6, the walking plate 6 is convenient for the staff to repair the top of the tunnel, and the first hydraulic rod 8 is vertically symmetrically installed on the walking plate 6. The two first hydraulic rods 8 are fixedly installed with the same detection ring 5 for detecting the initial support section of the tunnel. The outer wall of the beam 2 is installed with a rotatable second hydraulic rod 9 to support the two ends of the detection ring 5. The other end of the second hydraulic rod 9 is rotatably arranged on the inner side of the detection ring 5. The first hydraulic rod 8 and the second hydraulic rod 9 are used to lift the detection ring 5, which is convenient for the detection ring 5 to detect the tunnel. The front array of the detection ring 5 is provided with a number of supporting mechanisms 7 for supporting the inner wall of the tunnel. The supporting mechanism 7 is detachably connected to the inner wall of the tunnel. The supporting mechanism 7 is used to support the tunnel to prevent the steel bars or concrete on the inner wall of the tunnel from falling and injuring the staff.

[0021] The supporting mechanism 7 includes a mounting shell 701, which is fixedly mounted on the front side wall of the detection ring 5. A two-way hydraulic rod 702 is horizontally fixedly mounted in the mounting shell 701 through a mounting seat. Both output ends of the two-way hydraulic rod 702 are fixedly mounted with sliding blocks 703. The two output ends of the two-way hydraulic rod 702 are telescopically driven to drive the two sliding blocks 703 to slide relative to or toward each other. The sliding blocks 703 are slidably arranged in the mounting shell 701. An opening that matches the sliding block 703 is provided at the top of the mounting shell 701 to prevent the sliding block 703 from getting stuck. The top of the sliding block 703 passes through an opening for sliding connection and is installed with a first supporting rod 704 for rotational connection. The opening allows the sliding block 703 to be moved in a certain direction. During the sliding process, it will not get stuck on the mounting shell 701.

The two mounting blocks 707 are hinged with the second support rod 705. The other end of the first support rod 704 is rotatably installed on the inner side of the second support rod 705. The top of the two second support rods 705 is installed with the same rotating arc support plate 706 to support the inner wall of the tunnel. The arc support plate 706 is detachably connected to the inner wall of the tunnel. The movement of the first support rod 704 drives the second support rod 705 to rotate, thereby driving the arc support plate 706 to slide up or down, supporting or loosening the inner wall of the tunnel.

[0022] The walking mechanism 4 includes a walking gear 401, a support shaft is installed through the center of the walking gear 401, and both ends of the support shaft are rotatably arranged on the inner wall of the cavity. A rack 406 meshing with the walking gear 401 is fixedly installed at the bottom of the track 14, and the walking gear 401 meshes with the rack 406 in the track 14 to drive the vehicle body 1 to move. Cleaning wheels 402 are symmetrically provided on the front and rear sides of the walking gear 401 for cleaning the track 14. A first rotating shaft is installed through the center of the cleaning wheel 402, and the first rotating shaft is rotatably arranged on the inner wall of the cavity. Two vertically meshed driving gears 403 are installed above the walking gear 401, and the two driving gears 403 are each provided with a second rotating shaft in the center. The two ends of the second rotating shaft are rotatably arranged on the inner wall of the cavity, and the first rotating shaft and the second rotating shaft are both provided with a chain. Wheel 404, the sprockets 404 on the two first rotating shafts are each provided with a meshing chain 405, and the other ends of the two chains 405 are respectively mounted on the sprockets 404 on the two second rotating shafts, and a driving motor 408 and a second motor 407 are respectively fixedly installed on the inner side wall of the column 3, and the output shaft of the driving motor 408 extends out of the side wall of the cavity and is fixedly connected to the support shaft. The output shaft of the driving motor 408 rotates through the support shaft to drive the walking gear 401 to rotate, and the output shaft of the second motor 407 extends out of the side wall of the cavity and is fixedly connected to one of the second rotating shafts. The rotation of the output shaft of the second motor 407 drives one of the second rotating shafts to rotate, driving the two driving gears 403 to rotate in relative engagement, and the cooperation of the sprocket 404 and the chain 405 drives the two cleaning wheels 402 to rotate relative to each other, and the track 14 is cleaned.

[0023] The detection ring 5 is divided into three parts, and the three parts of the detection ring 5 are rotatably connected to each other, so that the detection ring 5 can be easily folded and unfolded.

[0024] A rotatable support plate 10 is installed on the outer walls of the two columns 3 on the same side. Chains 12 are installed on the front and rear sides of the support plate 10. The other end of the chain 12 on the rear side is set on the adjacent column 3. A winch 11 is installed in the front column 3. The other end of the chain 12 on the front side is set on the drum of the winch 11. The support plate 10 makes it convenient for the staff to repair the inner walls of the tunnel on both sides. When the winch 11 is started, the support plate 10 is driven to fall and retract through the chain 12.

[0025] The first hydraulic rod 8, the second hydraulic rod 9, the detection ring 5, the winch 11, the drive motor 408, the bidirectional hydraulic rod 702 and the second motor 407 are respectively electrically connected to the external control system, which facilitates the electrical control of the first hydraulic rod 8, the second hydraulic rod 9, the detection ring 5, the winch 11, the drive motor 408, the bidirectional hydraulic rod 702 and the second motor 407.

[0026] The working principle of the present invention is as follows: during operation, the first hydraulic rod 8 and the second hydraulic rod 9 are started through the console, and the first hydraulic rod 8 and the second hydraulic rod 9 prop up the detection ring 5. After reaching the appropriate position, the first hydraulic rod 8 and the second hydraulic rod 9 are controlled to be closed, and the power switch of the winch 11 is turned on. The winch 11 is started and drives the support plate 10 to fall through the chain 12. When it falls completely until the support plate 10 is horizontal, the winch 11 is closed, and the power switches of the detection ring 5, the drive motor 408 and the second motor 407 are turned on. The output shaft of the drive motor 408 rotates through the support shaft to drive the travel gear 401 to rotate, and the travel gear 401 engages with the rack 406 in the track 14 to drive the vehicle body 1 to move in the working direction. At the same time, the output shaft of the second motor 407 rotates to drive one of the second rotating shafts to rotate, thereby driving the two drive gears 403 to engage and rotate relative to each other, and the two cleaning wheels 402 are driven relative to each other through the cooperation of the sprocket 404 and the chain 405. Rotate to clean the track 14; when the detection ring 5 detects a problem and determines the position, the power switches of the detection ring 5, the drive motor 408 and the second motor 407 are turned off, and the power switch of the two-way hydraulic rod 702 is turned on. The two output ends of the two-way hydraulic rod 702 extend to drive the two sliding blocks 703 to slide relative to each other, and the sliding blocks 703 slide relative to each other through the first support rod 704 to drive the second support rod 705 to rotate, thereby driving the arc-shaped support plate 706 to slide upward and support the inner wall of the tunnel. After supporting, the two-way hydraulic rod 702 is controlled to be closed, and the staff repairs it. After the repair is completed, the power switch of the two-way hydraulic rod 702 is turned on to make the output end of the two-way hydraulic rod 702 contract, thereby driving the arc-shaped support plate 706 to slide downward, and after disengaging from the inner wall of the tunnel, the power switch of the two-way hydraulic rod 702 is turned off, and the power switches of the detection ring 5, the drive motor 408 and the second motor 407 are turned on, and then the inner wall of the tunnel in the working direction is inspected.
