Description

Technical Field

[0001] This invention relates to the field of bridge demolition, and in particular to a traction device and construction method for demolishing high-pier bridges with intelligent identification and automatic height and posture adjustment. Background Technology

[0002] With the continuous improvement of transportation infrastructure, high-pier bridges, due to their ability to adapt to complex terrain conditions, occupy an important position in the transportation networks of mountainous areas and river valleys. When high-pier bridges reach the end of their service life or undergo structural upgrades, they need to be demolished.

[0003] Currently, the demolition of high-pier bridges still primarily relies on traditional mechanical crushing and manual cutting. When using cutting techniques for bridge demolition, existing equipment generally suffers from insufficient coordination between the cutting mechanism and the lifting support system. During construction, the lifting support system must first be manually or in stages positioned to reliably support the bridge components, and then the cutting mechanism must be adjusted separately to the designated cutting position. The positions and postures of both require multiple, step-by-step calibrations, making the adjustment process cumbersome and time-consuming, severely hindering the overall efficiency of the demolition operation. Therefore, there is an urgent need to develop a high-pier bridge demolition traction device and supporting construction methods with intelligent recognition and automatic height and posture adjustment functions. This would achieve integrated and coordinated control of automatic height and posture adjustment for support and cutting operations, significantly improving demolition efficiency. Summary of the Invention

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] like Figure 1-2 As shown, a smart identification and automatic height and posture adjustment high-pier bridge demolition traction device includes a control mechanism 1, which includes a platform plate 11, a control box 13 and a vision sensor installed on the platform plate 11, and a control module inside the control box 13; a cutting mechanism 2 is detachably installed on the front end of the platform plate 11 to cut the bridge; a lifting mechanism 3 is detachably installed on the lower end face of the platform plate 11 to control the lifting of the platform plate 11; a clamping mechanism 4 is detachably installed on the lifting mechanism 3 to clamp the bridge close to the platform plate 11; and a movable base mechanism 5 is detachably installed on the lower end of the lifting mechanism 3. The movable base mechanism 5 includes a base 51 and a turntable 52 rotatably connected to the base 51. The upper end face of the turntable 52 is fixed to the lower end of the lifting mechanism 3, and movable wheels 53 are installed at the four corners of the base 51.

[0060] Specifically, the base 51 is horizontally positioned on the ground via four movable wheels 53. The turntable 52 is rotatably connected to the base 51 via a rotating shaft at its lower end. The lower end of the lifting mechanism 3 is detachably fixedly mounted on the turntable 52, and the lower end of the platform plate 11 is detachably fixedly mounted on the upper end of the lifting mechanism 3, thereby positioning the control box 13 and the vision sensor at the highest point of the device. When the base 51 moves on the ground via the four movable wheels 53, the entire device can move. When the turntable 52 rotates on the base 51 via the rotating shaft, it can drive the control mechanism 1, the cutting mechanism 2, the lifting mechanism 3, and the clamping mechanism 4 to rotate horizontally on the base 51 around the rotating shaft, thereby changing the orientation of the clamping opening between the platform plate 11 and the clamping mechanism 4.

[0061] During actual construction, the base mechanism 5 is moved to the construction area using four movable wheels 53, aligning the center mark of the base 51 with the preset reference point. Then, the four movable wheels 53 are locked to prevent further movement of the base 51. Next, using a crane or other equipment, the lifting mechanism 3 is lifted and installed on the turntable 52. The control mechanism 1, cutting mechanism 2, and clamping mechanism 4 are then assembled and connected, along with the circuit connections. At this point, a vision sensor captures images of the bridge, and the control module controls the lifting mechanism 3 to adjust the height of the platform plate 11 and the clamping mechanism 4. Simultaneously, the control module controls the mechanism installed on the base 51... The drive motor drives the turntable 52 to rotate, which in turn aligns the platform plate 11 with the opening of the clamping mechanism 4 to the bridge and clamps it. Then, the control mechanism 2 is controlled to complete the cutting. The clamping of the bridge by the platform plate 11 and the clamping mechanism 4 ensures the accuracy of the cutting position when the cutting mechanism 2 cuts. After the cutting is completed, each mechanism is disassembled, maintained, and stored. Throughout the process, the image information collected by the vision sensor is intelligently recognized by the control module, which sends instructions to automatically adjust the height and posture to support the bridge, while controlling the cutting mechanism 2 to complete the cutting operation. This achieves integrated and coordinated control, significantly improving the efficiency of demolition construction.

[0062] The control box 13 has a protective grille on its side to prevent debris from entering while ensuring heat dissipation.

[0063] As an optional solution, a laser rangefinder can also be installed on the platform plate 11 to collect distance data between the device and the pier. Simultaneously, a high-definition vision sensor can be used to collect images of the pier surface. The control module can then fuse and process the two types of data to extract key features such as the outline and position of the part of the pier to be cut, and then convert them into precise height and posture adjustment commands, making the device dismantling operation more accurate.

[0064] As an optional solution, the movable wheels 53 are omnidirectional rollers made of a blend of natural rubber and styrene-butadiene rubber, possessing good ground adaptability, cushioning performance, and wear resistance, enabling flexible movement of the device on the construction site. Each omnidirectional roller has a built-in electromagnetic braking mechanism. When the device moves to the designated working position, a braking command is issued through the control module, and the brake pads of the braking mechanism can quickly engage and lock with the roller, providing a large locking force to ensure no displacement of the device during operation. The upper end of the movable wheels 53 is mounted to the base 51 via wheel seats. The lower end of the base 51 has a groove for the wheel seats to be raised, lowered, and slidably mounted. By installing a control mechanism within the groove... The hydraulic cylinder for lifting the wheel seat, or the screw installed in the groove and threadedly connected to the wheel seat, controls the lifting and extending of the wheel seat within the groove. This controls the distance between the moving wheel 53 and the base 51, thus enabling the base 51 to remain level by controlling the four moving wheels 53 individually. This allows the device to maintain an overall level operating state for different ground environments. At the same time, an inclination sensor can be installed on the base 51 to monitor the level of the base 51 in real time. The control module then controls the distance between the four moving wheels 53 and the base 51 individually to ensure the level accuracy of the device.

[0065] As an optional technical solution, such as Figure 12 As shown, the base 51 has an opening slot facing the center of the turntable 52. A wedge block 54 slides in the opening slot, and an electric telescopic rod is installed between the wedge block 54 and the inner end of the opening slot. After the turntable 52 is rotated, in order to prevent the turntable 52 from being affected by cutting vibration during operation, the electric telescopic rod can be extended so that the wedge block 54 is inserted between the turntable 52 and the base 51. The friction formed by the upper and lower end faces of the wedge block 54 pressing against the turntable 52 and the base 51 respectively can lock the rotation of the turntable 52.

[0066] like Figure 3 As shown, in some embodiments, a signal receiver 14 is installed on the control box 13;

[0067] Specifically, the signal receiver 14 can stably receive external data, providing reliable data support for the control module. At the same time, it can also better connect wirelessly with portable wireless operating terminals, thereby facilitating remote control of the control module.

[0068] like Figure 4 As shown, in some embodiments, the cutting mechanism 2 includes a fixed base 21 that is fixed to the front end face of the platform plate 11; a guide plate 22 that slides up and down inside the platform plate 11; and a cutting chain 23 surrounding the guide plate 22.

[0069] Specifically, the fixed seat 21 is detachably fixed to the front end of the platform plate 11. The fixed seat 21 has a space for the guide plate 22 to slide and rise, and has two limiting ridges that slide through the two long sliding holes 221 on the guide plate 22. The cooperation between the two limiting ridges and the two long sliding holes 221 ensures that the guide plate 22 can only slide and rise within the fixed seat 21. At the same time, in order to realize the lifting and lowering of the guide plate 22, an electric telescopic rod can be installed between the guide plate 22 and the fixed seat 21. The lifting and lowering of the guide plate 22 is controlled by the electric telescopic rod. The cutting chain 23 is arranged around the guide plate 22. When the lower end of the guide plate 22 extends out of the fixed seat 21, it can drive the cutting chain 23 to extend out from the fixed seat 21, thereby cutting the bridge between the platform plate 11 and the clamping mechanism 4. The guide plate 22 is continuously lowered by controlling it until the cutting operation is completed.

[0070] The cutting chain 23 is made of high-strength alloy steel forged links, which are treated with multiple heat treatment processes to have excellent surface hardness and cutting toughness. The links adopt a low-friction transmission structure to improve transmission efficiency. The guide plate 22 is made of high-strength steel plate stamping, and the inner wall of the guide groove is inlaid with wear-resistant lining strips to avoid direct friction and wear of the links and extend service life. A drive wheel is installed at the upper end of the guide plate 22 to drive the cutting chain 23 to rotate on the guide plate 22. The drive wheel is driven by a drive motor.

[0071] like Figure 4 As shown, in some embodiments, the front end of the platform plate 11 is provided with an inwardly recessed mounting groove 12, and the rear end of the fixing seat 21 is fixed with an insert plate 24 that can be inserted into the mounting groove 12. The upper end of the insert plate 24 is slidably raised and lowered by a slide rod 25, and the lower end of the slide rod 25 is fixed with a bracket 26 that can penetrate and be inserted into the platform plate 11 and the insert plate 24.

[0072] Specifically, when assembling the cutting mechanism 2 and the platform plate 11, the fixed base 21 is lifted up so that the insert plate 24 is aligned with the mounting groove 12 and inserted into the mounting groove 12. Then, the slide bar 25 is pushed to slide down the fixed base 21, and then the insert bracket 26 is inserted through the platform plate 11 and the insert plate 24 to form a limit on both, thereby completing the quick installation of the cutting mechanism 2 and the platform plate 11.

[0073] The mounting plate is fixed to the rear end of the fixed base 21, and the slide rod 25 slides through the mounting plate. The insert 26 consists of a flat plate and two inserts. The middle part of the upper end of the flat plate is fixed to the lower end of the slide rod 25, and the two inserts are vertically fixed to the lower end of the flat plate. The front end of the flat plate slides against the rear end face of the fixed base 21, thereby forming a limit and ensuring that the insert 26 can only slide up and down. Then, the two inserts can be aligned with the limiting holes on the platform plate 11 and the insert plate 24. By simultaneously inserting into the limiting holes on the platform plate 11 and the insert plate 24, the limiting on the platform plate 11 and the insert plate 24 is formed, and the cutting mechanism 2 and the platform plate 11 are quickly installed.

[0074] In some embodiments, a spring 27 is provided between the insert 26 and the fixed base 21.

[0075] Specifically, by pressing the flat plate and the mounting plate against the two ends of the spring 27 respectively, the flat plate is prevented from sliding upwards with the insertion post, thereby automatically releasing the limit on the platform plate 11 and the insertion plate 24, thus ensuring the limiting effect of the insertion post on the platform plate 11 and the insertion plate 24.

[0076] like Figure 5-7 As shown, in some embodiments, the lifting mechanism 3 includes two main support columns 31, which are vertically parallel between the platform plate 11 and the turntable 52. The two main support columns 31 drive the platform plate 11 to rise and fall by telescoping. Four auxiliary columns 32 are vertically parallel between the platform plate 11 and the turntable 52. All four auxiliary columns 35 can telescop and extend with the platform plate 11. Fixed flanges 33 are fixed to both ends of the main support columns 31 and the auxiliary columns 32 for bolted connection with the platform plate 11 or the turntable 52. A power stud mechanism 34 is detachably installed between the platform plate 11 and the turntable 52 for controlling the telescoping of the main support columns 31. Four sleeves 35 are provided and slide on the four auxiliary columns 32 respectively. The upper end of the threaded column 36 is rotatably connected to the platform plate 11. The support platform 37 is detachably installed on the four sleeves 35 by bolts and threadedly connected to the threaded column 36. The clamping mechanism 4 is installed on the support platform 37.

[0077] Specifically, the upper ends of the two main support columns 31 and the four auxiliary columns 32 are fixed to the platform plate 11 by bolts through the fixing flange 33, achieving a detachable connection. The lower ends of the two main support columns 31 and the four auxiliary columns 32 are fixed to the turntable 52 by bolts through the fixing flange 33, achieving a detachable connection. The lower end face of the platform plate 11 and the upper end face of the turntable 52 are provided with circular grooves that match the fixing flange 33 at corresponding positions, thereby enabling faster installation and positioning of the two main support columns 31 and the four auxiliary columns 32 with the platform plate 11 and the turntable 52, improving installation efficiency.

[0078] When the platform plate 11 is raised or lowered, the two main bearing columns 31 are extended or retracted by the power stud mechanism 34, which can realize the raising or lowering of the platform plate 11. When the platform plate 11 is raised or lowered, the four auxiliary columns 32 are also extended or retracted. Through the extension and retraction of the two main bearing columns 31 and the four auxiliary columns 32, the stability of the platform plate 11 is ensured while avoiding lateral deviation. When the clamping mechanism 4 is raised or lowered, the threaded column 36 can be rotated. Through the threaded engagement between the threaded column 36 and the support platform 37, the lifting or lowering of the support platform 37 is controlled, thereby realizing the raising or lowering of the clamping mechanism 4 and completing the clamping mechanism 4 and the platform plate 11 to clamp the bridge.

[0079] The upper end of the threaded column 36 has a rotating flange seat 361. The flange seat 361 is connected to the platform plate 11 by bolts to achieve detachable installation and fixation. At the same time, a motor that drives the threaded column 36 to rotate is installed on the flange seat 361 to control the rotation of the threaded column 36.

[0080] As an optional solution, such as Figure 5-6 As shown, the main bearing column 31 includes an inner main bearing column 311, an outer main bearing column 312, and a connecting seat 313. The outer main bearing column 312 is a thick-walled tube structure that slides on the outside of the inner main bearing column 311. The upper end of the outer main bearing column 312 is installed on the platform plate 11 through a fixed flange 33, and the lower end of the inner main bearing column 311 is installed on the turntable 52 through a fixed flange 33. The connecting seat 313 is located on the outside of the lower end of the outer main bearing column 312.

[0081] The auxiliary column 32 includes an outer auxiliary column 321 and an inner auxiliary column 322. The outer auxiliary column 321 is a thick-walled tube structure that slides on the outside of the inner auxiliary column 322. The upper end of the outer auxiliary column 321 is installed on the platform plate 11 through a fixed flange 33, and the lower end of the inner auxiliary column 322 is installed on the turntable 52 through a fixed flange 33. The sleeve 35 slides on the outer auxiliary column 321. Thus, when the platform plate 11 is raised, the platform plate 11 will drive the outer auxiliary column 321, the threaded column 36, the support platform 37, and the sleeve 35 to rise synchronously. Only when the threaded column 36 is rotated can the support platform 37 drive the sleeve 35 to slide on the outer auxiliary column 321, thereby realizing the rise of the support platform 37 relative to the platform plate 11, and then realizing the clamping mechanism 4 and the platform plate 11 to clamp the bridge.

[0082] The power stud mechanism 34 includes a power stud 341, a square stud 342, a threaded seat 343, and a flange seat 344. The square stud 342, being a rectangular structure, is coaxially inserted and slids at the center of the power stud 341. The lower end of the power stud 341 and the upper end of the square stud 342 are detachably connected to the turntable 52 and the platform plate 11 via the flange seat 344, respectively, by bolts. The threaded seat 343 is threaded onto the power stud 341 and detachably fixed to the two connecting seats 313 by bolts. A motor that drives the square stud 342 to rotate is mounted on the upper flange seat 344. When the square stud 342 rotates, it can drive the power stud 341 to rotate. The power stud 341 rotates, and then through the thread between the power stud 341 and the threaded seat 343, the threaded seat 343 moves up and down along the power stud 341. This causes the two outer main bearing columns 312 to slide upward through the two connecting seats 313, thereby realizing the lifting and lowering of the platform plate 11. When the platform plate 11 rises, it drives the square column 342 to rise, while the height of the power stud 341 remains unchanged. This allows the square column 342 to gradually slide out of the power stud 341 and maintain the transmission state to the power stud 341. Moreover, because the power stud 341 is located below and connected to the support platform 37, it can better bear the pressure of the two outer main bearing columns 312 rising.

[0083] like Figure 8-9 As shown, in some embodiments, the clamping mechanism 4 includes a clamping seat 41 located above the support platform 37; two insertion shafts 42 are provided, which are vertically fixed to the lower end of the clamping seat 41 and can be inserted into the support platform 37; a clamping platform 44 is installed above the clamping seat 41; two side clamps 45 are provided, which are symmetrically slidably connected to the clamping platform 44; and two clamping screws 46 are provided, which are respectively rotated at the left and right ends of the clamping platform 44 and threadedly connected to the corresponding side clamps 45.

[0084] Specifically, the clamping seat 41 is vertically inserted into the support 37 via two mounting shafts 42, enabling the clamping seat 41 and the support 37 to be detachably installed. Through clamping, the clamping force acts in the opposite direction on the clamping table 44, and then is transmitted to the clamping seat 41 to press the support 37. With the two mounting shafts 42 vertically inserted into the support 37, the stability of the clamping mechanism 4 installed on the support 37 is ensured.

[0085] When actually clamping the bridge, the lifting mechanism 3 is controlled to raise the platform plate 11 above the bridge and the clamping platform 44 below the bridge. Then, the turntable 52 is controlled to rotate so that the bridge is located between the platform plate 11 and the clamping platform 44. Then, the lifting mechanism 3 is controlled to lower the platform plate 11 and raise the clamping platform 44 to achieve vertical clamping of the bridge. At the same time, the transmission clamping screw 46 rotates. Through the threaded connection between the clamping screw 46 and the side clamp 45, the side clamp 45 can move towards the bridge. Then, the side clamp 45 presses against the side of the bridge. Through the cooperation of the two side clamps 45, the device achieves lateral limiting and fixing of the bridge, thereby avoiding the device from moving laterally due to the cutting force during the cutting operation, which would affect the cutting accuracy.

[0086] The clamping table 44 has a sliding groove in the middle, and the side clamp 45 has a T-shaped structure. Its lower pointed end slides in the sliding groove and is threadedly connected to the clamping screw 46 located in the sliding groove. Both ends of the clamping table 44 are equipped with motors to drive the clamping screw 46 to rotate respectively.

[0087] As an optional solution, such as Figure 7 As shown, the support platform 37 includes a horizontal connecting plate 371, a tripod 372, a mounting tube 373, a positioning bolt 374, and a threaded block 375. The horizontal connecting plate 371 is arranged horizontally and is detachably fixed to four sleeves 35 by bolts. Two tripods 372 are symmetrically fixed to the front side of the horizontal connecting plate 371. Two mounting tubes 373 are vertically fixed to the two tripods 372 respectively for fitting with two mounting shafts 42 to achieve installation. In order to ensure the stability of the installation, locking holes 421 are provided horizontally on the two mounting shafts 42. By rotating the positioning bolt 374 and inserting it into the locking hole 421, the mounting shafts 42 and the mounting tubes 373 are limited, thereby ensuring the stability of the clamping mechanism 4 on the support platform 37 and facilitating quick disassembly and assembly. The threaded block 375 is fixed in the middle of the horizontal connecting plate 371 and is threadedly connected to the threaded post 36.

[0088] like Figure 11 As shown, in some embodiments, a horizontal shaft 43 is provided at the front end of the clamping seat 41 in the left-right direction, the front end of the clamping table 44 rotates on the horizontal shaft 43, and a telescopic rod 49 is installed between the rear end of the clamping seat 41 and the clamping table 44.

[0089] Specifically, after the cutting is completed, the cut bridge segment is located on the clamping platform 44. The bridge segment needs to be unloaded. At this time, the control telescopic rod 49 extends, which will push the clamping platform 44 to rotate on the clamping seat 41 around the horizontal axis 43, forming an inclined state of the clamping platform 44 with the front lower and the back higher, so that the cut bridge segment can automatically slide off the clamping platform 44, improving the efficiency of bridge unloading.

[0090] The telescopic rod 49 can be an electric telescopic rod or a hydraulic rod, and both ends of it are rotatably connected to the clamping seat 41 and the clamping table 44 through connecting shafts.

[0091] like Figure 9 As shown, in some embodiments, each side clamp 45 is provided with two L-shaped through slots 451, each L-shaped through slot 451 has a roller frame 452 that slides in it, and each roller frame 452 has a rubber roller 453 that rotates on it.

[0092] Specifically, the rubber roller 453 is installed on the inner side of the side clamp 45 through the cooperation of the roller frame 452 and the L-shaped through groove 451. When clamping the bridge, the rubber roller 453 can directly contact the bridge instead of the inner side of the side clamp 45. The elastic material of the rubber roller 453 allows the side clamp 45 to adapt to clamping uneven bridge sides. Moreover, since the roller frame 452 can slide back and forth in the L-shaped through groove 451, when the bridge position clamped by the rubber roller 453 is relatively convex and not conducive to clamping and fixing, the rubber roller 453 will automatically roll from the convex point to the concave point. With the roller frame 452 sliding in the L-shaped through groove 451, the rubber roller 453 can better achieve clamping and limiting fixation of the bridge in the left and right directions. In addition, when the clamping table 44 is rotated to the tilted state to remove the bridge section, the rubber roller 453 can also rotate on the roller frame 452 to form a rolling guide for the bridge to slide down, ensuring that the bridge section is removed smoothly.

[0093] like Figure 9-11 As shown, in some embodiments, the clamping table 44 has a mounting groove 47 at its front end, and a mounting shaft 471 is provided in the mounting groove 47 in the left-right direction. A horizontal clamp 48 is rotatably mounted on the mounting shaft 471. The horizontal clamp 48 includes a sleeve 481, a clamping plate 482, and an auxiliary roller 483. The sleeve 481 is sleeved on the mounting shaft 471, and the clamping plate 482 extends radially and is fixed on the sleeve 481. Both ends of the sleeve 481 are fixed with end plates. The auxiliary roller 483 rotates between the two end plates and is parallel to the sleeve 481. The mounting groove 47 has a limiting groove 472 at its front end and a limiting plate 473 at its rear end.

[0094] Specifically, a magnet is provided in the limiting groove 472, which can attract the end plate, thereby causing the end plate to drive the sleeve 481 to rotate on the mounting shaft 471. Then, the auxiliary roller 483 automatically enters the limiting groove 472. At this time, the uppermost end of the auxiliary roller 483 is lower than the upper plane of the clamping table 44, while the clamping plate 482 is in an upward and forward inclined state, protruding from the upper plane of the clamping table 44. When clamping the bridge, under the influence of the clamping force, the bridge will press down on the clamping plate 482, thereby causing the clamping plate 482 to have a tendency to rotate into the limiting groove 472. This tendency is limited by the auxiliary roller 483 pressing against the limiting groove 472, keeping the clamping plate 482 in this state, forming a protruding clamp on the lower end face of the bridge, thereby preventing the bridge from moving back and forth relative to the clamping table 44.

[0095] During unloading, the clamping table 44 rotates to an inclined state, and the bridge section slides downward on the clamping table 44. This causes the clamping plate 482 to rotate on the mounting shaft 471 through the sleeve 481, thereby causing the auxiliary roller 483 to rotate out of the limiting groove 472. The auxiliary roller 483 then replaces the clamping plate 482 to contact the lower end of the bridge section until the clamping plate 482 presses against the limiting plate 473. At this time, the auxiliary roller 483 completely replaces the clamping plate 482 to support the bridge section. With the rotation of the auxiliary roller 483 between the two end plates, the bridge section slides down more smoothly, further improving the unloading efficiency while reducing the damage to the clamping table 44 when the bridge section slides down.

[0096] like Figure 1-2 As shown, a construction method for a high-pier bridge demolition traction device using intelligent identification and automatic height and posture adjustment is described. This method includes...

[0097] S1, Positioning

[0098] The mobile base mechanism 5 is moved to the designated work area on the construction site. The position of the base 51 is slowly adjusted using the moving wheels 53 at the bottom of the base 51, ensuring precise alignment of the center mark of the base 51 with the preset reference point. After alignment, a command is sent via the control module to activate the electromagnetic braking mechanism built into the moving wheels 53. The brake pads and rollers engage tightly to lock the base 51, preventing slippage. The horizontal state of the base 51 is monitored in real time by a tilt sensor, and the control module individually controls the distance between the four moving wheels 53 and the base 51 to ensure the device's horizontal accuracy.

[0099] S2, Assembly

[0100] The main support column 31 and auxiliary column 32 are lifted in sequence to align the connection hole of the fixed flange 33 with the reserved circular groove of the turntable 52, thus achieving initial positioning. Then, the high-strength connecting bolts are tightened in an alternating diagonal order to ensure that the fixed flange 33 fits tightly with the turntable 52 without any gaps or shaking. After the repowered stud mechanism 34 is installed as described above, the threaded seat 343 and the two connecting seats 313 are tightened and fixed with bolts, and the cross connecting plate 371 of the support platform 37 is tightened and fixed with the four sleeve seats 35 with bolts. Then, the clamping mechanism 4 is lifted and the two mounting tubes 373 are inserted through the two mounting shafts 42 to complete the installation. Then, the platform plate 11 is lifted and tightened with the upper fixed flange 33, flange seat one 361, and flange seat two 344 with threads to complete the installation of the control mechanism 1. Then, the fixed seat 21 is lifted and the insert plate 24 is inserted into the mounting slot 12. Then, the insert bracket 26 is used for through-fitting to complete the initial assembly of the device. After the electrical connection between the control module, the sensor, and the motor is completed, the assembly is completed.

[0101] S3, Homework

[0102] The distance data between the device and the bridge pier is collected by a laser rangefinder sensor, and the surface image of the bridge pier is captured by a high-definition vision sensor. The control module analyzes the data through a built-in algorithm, extracts the position parameters of the part to be cut, and generates height and angle adjustment commands. The commands are transmitted to the lifting mechanism 3 to extend and retract the main support column 31. The tilt sensor provides real-time feedback of horizontal data, and dynamic fine-tuning is used to keep the platform level. After the height is adjusted to the correct position, the control module sends an angle adjustment command to the moving base mechanism 5, causing the turntable 52 to rotate the cutting mechanism to the cutting position, and locking the turntable 52 with a wedge block 54. Then, the control platform plate 11 and the clamping mechanism 4 clamp the bridge, and simultaneously control the two side clamps 45 to retract and clamp laterally. The cutting mechanism is started, and the cutting chain 23 moves along the guide track of the guide plate 22 to precisely cut the part of the bridge pier to be cut.

[0103] S4, Disassembly

[0104] After the cutting operation is completed, the cutting mechanism is turned off, the cut bridge sections are unloaded, and the equipment is disassembled and transported to a temporary storage area using hoisting equipment. After rust removal, oiling and maintenance, the sections are classified and stored for future reuse.
