[0020] Due to the geographical position of bridge and the influence of environment, the quality of bridge will gradually decline after using to certain years, in order to avoid potential safety hazard, dangerous bridge needs to be demolished and reconstructed, since bridge is usually built by steel reinforced concrete structure, in order to recycle steel bar and other recyclable materials, cutting equipment is needed to cut steel reinforced concrete, when recycling steel bar at bridge pier, bridge pier needs to be cut, before the equipment moves to bridge pier, limit rod two 38 and cutting table 31 are moved horizontally by electric telescopic rod two 39, so that tension spring two 37 is contracted, so as to avoid that adjusting mechanism 3 is scratched with bridge pier when moving, after two cutting tables 31 are adjusted to the two sides of bridge pier by external mechanical arm, electric telescopic rod two 39 is stopped, cutting table 31 and limit rod two 38 are moved horizontally outward by the elastic force of tension spring two 37, so that fitting wheel 34 is tightly attached to the surface of bridge pier, driven block 33 is deflected with fixed rod one 36 as center by the pressure of cutting table 31 generated by tension spring two 37, so that the included angle between driven block 33 and cutting table 31 is changed, when non-cylindrical bridge pier is processed, adjusting mechanism 3 can ensure that cutting equipment is always close to the surface of bridge pier.
[0021] Example two, as Figure 2 , Figure 3As shown, based on the above embodiment, a further component includes a rupture mechanism 2 disposed above the cutting table 31. The rupture mechanism 2 includes a hydraulic actuator 21, a second drive motor 22, a drill bit 23, a fixed plate 24, a first limiting rod 25, a conical block 26, a slider 27, a first tension spring 28, and a first rotating plate 29. The output shaft of the second drive motor 22 is fixedly connected to the first rotating plate 29, the first rotating plate 29 is fixedly connected to the fixed plate 24, the drill bit 23 is fixedly connected to the fixed plate 24, the slider 27 is fixedly connected to the fixed plate 24, the slider 27 is slidably inserted into the first limiting rod 25, the first limiting rod 25 is fixedly connected to the first rotating plate 29, one end of the first tension spring 28 is fixedly connected to the first rotating plate 29, the other end of the first tension spring 28 is fixedly connected to the slider 27, and the conical block 26 is in contact with the fixed plate 24. When cutting the bridge pier, the top plate 1 is moved to the surface of the bridge pier by an external robotic arm. Then, the drive motor 22 is started. The drive motor 22 drives the rotating plate 29, the fixed plate 24 and the drill bit 23 to rotate. The drill bit 23 drills a hole in the upper surface of the bridge pier. After drilling, according to the cutting standard, the operating platform 14 is moved vertically to the target position by the electric telescopic rod 111 and the adjusting block 18, so that the drill bit 23 is in the previously drilled hole. After the adjusting mechanism 3 cuts the external concrete and steel bars, the hydraulic device 21 applies pressure to the upper surface of the conical block 26, so that the conical block 26 moves vertically downward, and the two sets of drill bits 23 move horizontally in opposite directions. As the conical block 26 continues to move downward, the concrete at the center of the bridge pier breaks from the drilled hole to the edge.
[0022] Example 3, as Figure 5 , Figure 6 As shown, based on the above embodiment, it also includes an operating platform 14 slidably inserted into one end of the limiting rod 38. The operating platform 14 is fixedly connected to the tension spring 37 and the electric telescopic rod 39. An adjusting block 18 is fixedly connected to the upper surface of the operating platform 14. A connecting block 13 is slidably connected to the surface of the adjusting block 18. An electric telescopic rod 111 is fixedly installed inside the connecting block 13. The output end of the electric telescopic rod 111 is fixedly connected to the adjusting block 18. The electric telescopic rod 111 drives the adjusting block 18 and the operating platform 14 to move vertically, which can adjust the cutting thickness of the bridge pier, thereby avoiding the bridge pier from being too high and tilting, and improving the safety of the equipment during use.

The limiting blocks 110 are attached to the inner wall of the top plate 1. A drive motor 15 is fixedly installed on the upper surface of the top plate 1. A gear 16 is fixedly connected to the output shaft of the drive motor 15. A gear ring 17 meshes with the surface of the gear 16. The gear ring 17 is fixedly connected to the connecting block 13, and the gear 16 is rotatably connected to the top plate 1. The drive motor 15 drives the gear 16 to rotate, so that the gear ring 17 meshes with the surface of the gear 16 drives the connecting block 13 and the operating table 14 to rotate. This allows the adjusting mechanism 3 to move in a circle along the surface of the pier, thereby automatically cutting off the pier completely and improving the convenience of using the equipment. The receiving block 19 and the limiting blocks 110 can limit the connecting block 13 when it rotates, improving the stability of the equipment during operation.
[0024] Example 5, such as Figure 1 As shown, based on the above embodiment, it also includes two sets of mounting brackets 11 fixedly installed on the upper surface of the top plate 1. Each set of mounting brackets 11 has two sets of mounting holes 12. The mounting brackets 11 and mounting holes 12 facilitate the assembly of the device with the external robotic arm, reduce the installation difficulty, and facilitate the disassembly and assembly of the device, making it easier for staff to maintain the device.
[0025] Example 6, as Figure 4 , Figure 7 As shown, based on the above embodiment, it also includes a pressure booster 42 fixedly installed on one side of the connecting block 13, a connecting pipe 41 fixedly installed on the lower surface of the pressure booster 42, a water jet head 44 fixedly installed inside the cutting table 31, a connecting plate 4 attached to the surface of the cutting table 31, a bolt 43 attached to the upper surface of the connecting plate 4, the bolt 43 being threadedly connected to the cutting table 31, and two sets of connecting pipes 45 fixedly installed on one side of the connecting plate 4. Both sets of connecting pipes 45 are connected to the water jet head 44. The pressure booster 42 provides high-pressure water flow to the water jet head 44, and the high-pressure water flow is sprayed onto the surface of the bridge pier through the water jet head 44, which can cut the concrete outside the bridge pier. By adjusting the distance between the adjusting mechanism 3 and the bridge pier, the cutting range of the water jet head 44 can be adjusted, thereby facilitating the subsequent cutting of the reinforcing bars. At the same time, when the concrete is crushed by the water jet head 44, the water vapor generated during the spray can also significantly reduce the dust generated during cutting.
[0026] Example 7, as Figure 4 , Figure 9As shown, based on the above embodiment, it further includes a servo motor 5 fixedly installed inside the cutting table 31. A rotating plate 51 is fixedly connected to the output shaft of the servo motor 5. The rotating plate 51 is rotatably connected to the cutting table 31. A receiving rod 52 is fixedly connected to the surface of the rotating plate 51. A fixing rod 53 is fixedly connected to the surface of the rotating plate 51. A limit plate 55 is fixedly connected to one end of the fixing rod 53. A servo motor 56 is fixedly installed on one side of the limit plate 55. A cutting wheel is fixedly connected to the output shaft of the servo motor 56. 54. The cutting wheel 54 is rotatably connected to the limiting plate 55. The servo motor 5 drives the two sets of rotating plates 51 to rotate. The fixing rod 53 causes the limiting plate 55, the cutting wheel 54 and the servo motor 56 to deflect around the receiving rod 52. After the concrete on the outside of the pier is crushed, the cutting wheel 54 can deflect to the internal steel reinforcement. The servo motor 56 drives the cutting wheel 54 to rotate, thereby cutting the steel reinforcement inside the pier. This achieves the effect of cutting the concrete and steel reinforcement separately.
