A shaft hole is provided in the upper right corner of the mobile support 1, and a fixing shaft is provided in the upper left corner of the rotating support 2. The fixing shaft is rotatably connected to the shaft hole. The front and rear ends of the fixing shaft extend to the right to form a support composed of a number of fixing rods, and the bottom end of the support extends to the lower side of the road bridge 10 to the left. The fixing shaft, the support composed of a number of fixing rods, and the part of the support extending to the left together constitute the rotating support 2. The rotating mechanism 3 includes two gears driven by a motor. One gear is fixed on the rotating shaft of the motor, and the other gear is fixed on the fixing shaft of the rotating support 2.

[0061] The first abutting assembly 4 is vertically fixed on the part of the rotating support 2 located on the lower side of the road bridge 10. A roller is provided on the top surface of the first abutting assembly 4 to facilitate rolling abutment with the bottom surface of the road bridge 10 when the maintenance device moves.

[0062] The controller (not shown in the figure) is electrically connected to the rotating mechanism 3 and the driving mechanism 9 respectively, and is used for construction personnel to control and drive the maintenance device.

[0063] In some technical solutions, the first abutting assembly 4 is slidably and fixably arranged on the rotating support 2 up and down.

[0068] In this embodiment, it further includes:

[0069] The first lifting mechanism 5 is arranged on the first support frame 201 and is connected to the second support frame 202, and is used to control the distance between the first support frame 201 and the second support frame 202;

[0070] The first lifting mechanism 5 is electrically connected to the controller, and the controller is used to control the opening and closing of the first lifting mechanism 5.

[0071] In this technical solution, the first lifting mechanism 5 is a cylinder, which is vertically fixed on the first support frame 201. The telescopic shaft of the first lifting mechanism 5 is fixed on the second support frame 202. By adjusting the position of the second support frame 202 with the cylinder, it is convenient to use.

[0072] In this embodiment, the first support frame 201 is provided with at least two guiding holes, and the second support frame 202 is correspondingly provided with at least two guiding rods 203. Both ends of the guiding rod 203 extend to both sides of the guiding hole, and a limiting member 204 is provided at one end of the guiding rod 203 away from the second support frame 202. The contour of the limiting member 204 is larger than the contour of the guiding hole.

[0073] In this technical solution, the first support frame 201 is provided with four guiding holes that are symmetric in the front-back and left-right directions. On the top surface of the second support frame 202, there are four guiding rods 203 that are symmetric in the front-back and left-right directions. The top ends of the guiding rods 203 extend above the first support frame 201. The limiting member 204 is a limiting rod and is provided in two. The two limiting members 204 are respectively fixed on the two fixing rods at the front side and the two fixing rods at the back side. The setting of the limiting member 204 prevents the guiding rod 203 from slipping downward through the guiding hole, ensuring the safety of the maintenance device.

[0074] In this embodiment, it further includes:

[0075] A second lifting mechanism 6. The first abutting component 4 is slidably arranged on the rotating bracket 2. The second lifting mechanism 6 is connected to the first abutting component 4, and the second lifting mechanism 6 is used to drive the first abutting component 4 to move;

[0076] The second lifting mechanism 6 is electrically connected to the controller, and the controller is used to control the opening and closing of the second lifting mechanism 6.

[0077] In this technical solution, the second lifting mechanism 6 is a cylinder, which is fixed on the left side of the rotating bracket 2 and is located below the first abutting component 4. By controlling the position of the telescopic shaft of the second lifting mechanism 6, the height position of the first abutting component 4 can be adjusted, which is convenient for maintaining the abutting force of the first abutting component 4.

[0078] In this embodiment, it further includes:

[0079] A second abutting component 7, which is arranged on the moving bracket 1 at an angle to the vertical direction and is used to abut against the inner side wall of the road bridge 10;

[0080] A third abutting component 8, which is arranged on the rotating bracket 2 and is used to abut against the outer side wall of the road bridge 10.

[0081] In this technical solution, the second abutting component 7 is horizontally slidable and fixable on the moving bracket 1 from left to right, and the third abutting component 8 is slidable and fixable on the left side of the first support frame 201 of the rotating bracket 2 from left to right. The second abutting component 7 and the third abutting component 8 are similar in structure to the first abutting component 4, and are both rollers respectively arranged on the moving bracket 1 and the rotating bracket 2. During use, the left and right positions of the second abutting component 7 and the third abutting component 8 are adjusted so that they respectively abut against the left and right side walls of the road bridge 10, providing fixation in the second direction for the maintenance device and improving stability.

[0082] In some technical solutions, the second abutting component 7 is arranged obliquely with respect to the horizontal plane, and this arrangement is due to the fact that the side surface of the road bridge 10 is usually arranged as an inclined surface or a curved surface.

[0083] In some other technical solutions, the first abutting component 4 is arranged obliquely with respect to the vertical direction.

[0084] The embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments.
