[0024] During operation, in the process of concrete bridge construction, it is necessary to use cutting equipment to perform cutting operations at designated positions to meet the construction requirements of the bridge; when the existing concrete bridge cutting equipment is in use, it can only cut the bridge structure surface within a fixed range, which greatly limits the operating range of the cutting equipment and requires frequent adjustment of the operating position of the cutting equipment, affecting the efficiency of the cutting operation, and the moving cutting equipment needs to repeatedly adjust the motion trajectory of the cutting operation again. The present application works through an auxiliary device. When cutting the bridge, the telescopic mechanism 414 is started, and the telescopic rod 415 inside the moving cavity 401 pushes the limit rod 402 to move, so that the moving frame 2 moves to a suitable position, thereby achieving the cutting operation range. The adjustment can meet different cutting operation requirements without repeatedly adjusting the motion trajectory of the cutting operation. Then, with the cooperation of the moving mechanism 407 and the lifting device 408, the cutting tool 410 is moved to a suitable position. Then, the power device 409 is started, and the cutting tool 410 is operated. At the same time, the power device inside the moving block 405 is started, and the small roller 413 rotates, so that the moving block 405 drives the connecting frame plate 406 to move along the moving hole 403. After the connecting frame plate 406 moves to the end of the limit rod 402, the supporting device 412 inside the mounting hole 411 is operated, so that the moving block 405 rises to the highest position, and the small roller 413 continues to move along the moving groove 404, thereby ensuring the efficiency of the cutting operation.

[0025] Mounting holes 411 are provided at the top of both ends of the connecting frame plate 406; a supporting device 412 is installed inside the mounting hole 411; a small roller 413 is installed at the bottom of the moving block 405; the horizontal plane where the bottom end face of the small roller 413 is located is lower than the horizontal plane where the bottom end face of the moving block 405 is located; a power device is installed inside the moving block 405, and the power device acts on the small roller 413; when the supporting device 412 is in operation, the bottom end face of the small roller 413 contacts the bottom end face of the inner wall of the moving hole 403; when the supporting device 412 is not in operation, the horizontal plane where the bottom end face of the small roller 413 is located coincides with the horizontal plane where the bottom end face of the inner wall of the moving groove 404 is located;

[0026] During operation, after the connecting frame plate 406 moves to the end of the limit rod 402, the supporting device 412 inside the mounting hole 411 operates, so that the moving block 405 rises to the highest position, and the small roller 413 continues to move along the moving groove 404, avoiding frequent adjustment of the working position of the cutting equipment.

[0027] Working principle: During the construction of concrete bridges, cutting equipment is required to perform cutting operations at designated locations to meet the construction requirements of the bridges. When the above-mentioned concrete bridge cutting equipment is in use, it can only cut the bridge structure surface within a fixed range, which greatly limits the operating range of the cutting equipment and requires frequent adjustment of the operating position of the cutting equipment, affecting the efficiency of the cutting operation. Moreover, the moving cutting equipment needs to repeatedly adjust the motion trajectory of the cutting operation. The present application works through an auxiliary device. When cutting the bridge, the telescopic mechanism 414 is started, and the telescopic rod 415 inside the moving cavity 401 pushes the limit rod 402 to move, so that the moving frame 2 moves to a suitable position, thereby adjusting the cutting operation range to meet different requirements. The same cutting operation requirements are met, and there is no need to repeatedly adjust the motion trajectory of the cutting operation. Then, with the cooperation of the moving mechanism 407 and the lifting device 408, the cutting tool 410 is moved to a suitable position. Then, the power device 409 is started, and the cutting tool 410 is operated. At the same time, the power device inside the moving block 405 is started, and the small roller 413 rotates, so that the moving block 405 drives the connecting frame plate 406 to move along the moving hole 403. After the connecting frame plate 406 moves to the end of the limit rod 402, the supporting device 412 inside the mounting hole 411 is operated, so that the moving block 405 rises to the highest position, and the small roller 413 continues to move along the moving groove 404, thereby avoiding frequent adjustment of the working position of the cutting equipment and ensuring the efficiency of the cutting operation.
