Technical Field
[0001] This application relates to the technical field of breast wall removal, and in particular to a breast wall removal device and method thereof. Background Technology
[0002] The main components of the demolition of the old sluice gate structure include: the traffic bridge, the breast wall, the gate, and supporting brackets. Except for the breast wall, the demolition of the other structures is relatively simple and convenient. Although the breast wall has relatively little reinforcement, its massive size and proximity to the temporary water-blocking valve make its demolition highly dangerous.
[0003] When dismantling the breast wall, workers need to cut and drill holes in it. Currently, most of the work requires workers to use hand-held cutting and drilling tools.
[0004] The dismantling, cutting, and drilling of the breast wall takes a long time, and workers are prone to fatigue from holding the equipment for extended periods, resulting in high labor intensity for the workers. Summary of the Invention
[0005] To reduce the labor intensity of workers, this application provides a breast wall removal device and removal method.
[0006] Firstly, this application provides a breast wall removal device, which adopts the following technical solution:
[0007] A breast wall removal device includes a base, which is arranged horizontally. A pedestal is slidably connected to the base along its own length. A movable seat is sleeved on the pedestal, and a turntable is sleeved on the movable seat. The turntable is rotatably connected to the movable seat. A drilling tool for drilling holes in the breast wall and a cutting device for cutting the breast wall are respectively arranged on both sides of the turntable. A gear ring is fixedly provided on the side of the turntable facing the base, and a drive gear is meshed in the gear ring. A mounting seat is fixedly provided on the side of the movable seat facing the base. A first drive motor is mounted on the side of the mounting seat facing the gear ring, and the output shaft of the first drive motor is fixedly connected to the drive gear.
[0008] Using the above technical solution, the worker starts the first drive motor, which rotates the turntable via the drive gear and gear ring, thereby pointing the drill or cutting device toward the breast wall. During cutting or drilling, the drill or cutting device can move horizontally via the base and vertically via the moving base, thus continuously adjusting the cutting or drilling position. This structure eliminates the need for workers to hold the equipment, effectively reducing their workload.
[0009] Optionally, the base includes a connecting seat and a one-way screw. The bottom of the one-way screw is rotatably connected to the side wall of the connecting seat away from the base. A limit rod is provided on one side of the one-way screw. The limit rod passes through the movable seat and is slidably adapted between the two. A driven bevel gear is fixedly connected to the bottom of the one-way screw. A second drive motor is installed on the connecting seat. The output shaft of the second drive motor is fixedly connected to a driving bevel gear that meshes with the driven bevel gear. The movable seat is sleeved on the one-way screw and the two are threadedly connected. The one-way screw includes several spliced screws. The spliced screws are placed sequentially in the vertical direction. An installation assembly is provided between two adjacent spliced screws to connect and fix them. The installation assembly includes an installation rod. The installation rod is fixedly connected to the end face of the bottom of the spliced screw. An installation groove is opened on the end face of the top of the spliced screw for threaded connection with the installation rod.
[0010] Using the above technical solution, workers assemble the splicing screw into a one-way screw using the mounting rod and mounting slot, so that the one-way screw can be spliced into a suitable length according to the dismantling height; the second drive motor starts and rotates the one-way screw through the active bevel gear and the driven bevel gear, so that the moving seat moves in the vertical direction, thereby causing the drilling tool or cutting device to move in the vertical direction.
[0011] Optionally, a fixing plate is provided in the mounting groove, a hanging rod is fixed between the fixing plate and the mounting rod, a fixing block is fixed on the side wall of the fixing plate facing the mounting rod, a limit block is provided between the fixing plate and the mounting rod, a pressing surface is opened on the side of the limit block facing the fixing block, a guide rod is slidably connected in the limit block, the guide rod passes through the limit block and is fixedly connected to the fixing block, a return spring is fixed between the limit block and the fixing block, a limit groove is opened on the inner side wall of the splicing screw at the mounting groove to fit the limit block, a threaded hole is opened in the splicing screw, the threaded hole communicates with the mounting groove at the top of the splicing screw, a trigger rod is threadedly connected in the threaded hole of the splicing screw, one end of the trigger rod passes through the mounting rod and abuts against the pressing surface, an avoidance hole is opened in the mounting rod for the trigger rod to pass through, a groove is opened on the end face of the trigger rod away from the fixing plate, and a handle is fixed in the groove of the trigger rod.
[0012] Using the above technical solution, when splicing unidirectional lead screws, the operator screws the trigger rod into the threaded hole until the trigger rod is pressed against the limiting block by the extrusion surface, thereby pushing the limiting block into the limiting groove, so that it is not easy for two adjacent splicing lead screws to rotate relative to each other; the operator can rotate the trigger rod by the handle, which makes it convenient for the operator to rotate the trigger rod when disassembling the unidirectional lead screw.
[0013] Optionally, the base includes several splicing seats and several splicing components. Adjacent splicing seats are aligned end to end and abut against each other. The splicing components connect and fix adjacent splicing seats. A through groove is opened on the surface of the splicing seat facing the base. A rack is fixed on the inner bottom wall of the splicing seat at the through groove. The connecting seat is slidably adapted to the through groove. A storage groove is opened on the side wall of the connecting seat facing the rack. A traveling gear that meshes with the rack is set in the storage groove. A rotating roller is fixed in the traveling gear. Both ends of the rotating roller are rotatably connected to the connecting seat. Stabilizing blocks are fixed on both sides of the connecting seat. A stabilizing groove that is slidably adapted to the stabilizing block is opened on the inner side wall of the splicing seat at the through groove. A cavity is opened in the connecting seat. The cavity is opened on the side of the storage groove away from the base. A third drive motor is installed in the cavity. A drive wheel is fixedly connected to the end of the output shaft of the third drive motor. A driven wheel is fixedly connected to the rotating roller. A transmission belt is wound between the drive wheel and the driven wheel. An avoidance groove for the transmission belt to pass through is opened through the connecting seat.
[0014] Using the above technical solution, workers assemble the splicing base into a base using splicing components, so that the base can be assembled into a suitable length according to the width of the breast wall to be removed; the third drive motor starts to make the driving wheel rotate, the driving wheel makes the driven wheel rotate through the transmission belt, and the driven wheel makes the traveling gear roll along the rack through the rotating roller, thereby making the cutting device or drill move in the horizontal direction.
[0015] Optionally, the cutting device includes a fourth drive motor, a mounting platform, a clamping ring, and a blade. A slide is provided on one side of the turntable, and a storage cavity is opened on the surface of the slide away from the turntable. The fourth drive motor is installed in the storage cavity. The mounting platform is fixedly connected to the output shaft end of the fourth drive motor. The clamping ring is located on the side of the mounting platform away from the fourth drive motor. The blade is located between the mounting platform and the clamping ring. A locking rod is fixedly provided on the side wall of the mounting platform facing the clamping ring. The locking rod passes through the blade and the clamping ring, and the locking rod is threadedly connected to the clamping ring.
[0016] Using the above technical solution, after the blade is fitted onto the locking rod, the operator uses the clamping ring and mounting platform to press and fix the blade, which makes it convenient for the operator to replace the blade; after the fourth drive motor is started, the drive motor drives the blade to rotate through the mounting platform and clamping ring, so that the blade cuts the breast wall when it rotates.
[0017] Optionally, the clamping ring includes a fixed ring and a rotating ring. The fixed ring abuts against the blade and slides with the locking rod. The fixed ring has a rod fixed to its side wall facing the mounting platform. The surface of the blade has a first insertion hole that fits the insertion of the rod. The surface of the mounting platform facing the fixed ring has a second insertion hole that fits the insertion of the rod. The rotating ring is rotatably connected to the fixed ring away from the surface of the blade and is threadedly connected to the locking rod.
[0018] Using the above technical solution, the operator rotates the rotating ring, which inserts the insertion rod into the first and second insertion holes through the fixed ring; when the fourth drive motor starts, the mounting platform rotates the blade through the insertion rod, thereby making the blade rotate synchronously with the fourth drive motor.
[0019] Optionally, supports are provided on both sides of the slide block, the supports are fixedly connected to the turntable, a slide rod is rotatably connected between the two supports, the slide block is sleeved on the slide rod and the two rotate synchronously, and a fifth drive motor that drives the slide rod to rotate is installed on the side wall of the support.
[0020] Using the above technical solution, the staff starts the fifth drive motor to rotate the slide block through the slide rod, thereby changing the tilt direction of the blade and thus changing the cutting direction.
[0021] Optionally, the slide block has a through cavity on the side wall facing the support for the slide rod to pass through. A slider is fixed on the inner wall of the slide block in the cavity. The side wall of the slide rod has a groove adapted to slide with the slider. The fourth drive motor is a dual-axis motor. The output shaft of the fourth drive motor away from the mounting platform is fixedly connected to a turntable. A linkage rod is hinged to the side wall of the turntable away from the fourth drive motor. The hinge point between the linkage rod and the turntable is not at the rotation center of the turntable. A through hole is opened on the inner wall of the slide block in the receiving cavity. A push rod is slidably connected in the through hole. A synchronization plate is fixed on the slide rod. The synchronization plate is set between the support and the slide block. An adjusting spring is fixed between the synchronization plate and the slide block. One end of the push rod abuts against the synchronization plate, and the other end of the push rod is hinged to the linkage rod.
[0022] Using the above technical solution, when the fourth drive motor starts, it moves the linkage rod via the turntable, thereby pressing or pulling the push rod. When the push rod is pressed, it presses against the synchronous plate, and the slide block slides due to the reaction force; when the push rod is pulled, the adjusting spring releases its elasticity, causing the slide block to return to its original position. Through this structure, the cutting device reciprocates during the cutting process, thereby improving the cutting effect.
[0023] Optionally, the end of the drill bit away from the drill bit is hinged to the turntable. An adjusting rod is provided between the drill bit's cylinder and the turntable. The adjusting rod includes a fixed part and a rotating part. The fixed part is hinged to the drill bit's cylinder, and the rotating part is rotatably connected to the fixed part away from the drill bit's side wall. An adjusting hole is provided on the surface of the turntable facing the drill bit, which is threadedly connected to the rotating part.
[0024] Using the above technical solution, the operator rotates the rotating part to adjust its length within the adjustment hole, thereby adjusting the angle between the drill bit barrel and the turntable, thus achieving the adjustment of the angle at which the drill bit enters the breast wall.
[0025] Secondly, this application provides a method for dismantling a breast wall, employing the following technical solution:
[0026] A method for dismantling a breast wall includes the following steps:
[0027] S1. Erect a bridge girder erector above the breast wall, and at the same time, erect scaffolding on one side of the breast wall;
[0028] S2. The surveyors will draw the cutting holes, cutting lines, hoisting holes, and numbers on the surface of the breast wall according to the cutting position and hole layout diagram.
[0029] S3. Use a breast wall demolition device for cutting and drilling;

[0031] S5. The demolished breast wall concrete blocks are crushed and backfilled into the dredged sand and gravel pit in the downstream river channel.
[0032] By adopting the above technical solution, the bridge erecting machine effectively solves the problem of limited construction space, and it is stable in starting and operation, with good strength and rigidity, high safety factor and construction efficiency, resulting in significant economic benefits. It is also less likely to affect upstream temporary water-blocking gates and cause water pollution, demonstrating outstanding benefits in terms of safety and the ecological environment.
[0033] In summary, this application includes at least one of the following beneficial technical effects:
[0034] 1. The connecting seat slides along the base, thereby enabling the cutting device or drill to move horizontally, and the moving seat slides along the guide rod, thereby enabling the cutting device or drill to move vertically, thus allowing the position of the cutting device or drill to be adjusted;

[0052] During the dismantling of the breast wall, the workers adjusted the positions of the cutting device 5 and the drill 6 using the movable seat 3. The workers then drilled holes in the breast wall using the drill 6. After drilling, the workers rotated the turntable 4, thereby orienting the cutting device 5 toward the breast wall, and then started the cutting device 5 to cut the breast wall.
[0053] refer to Figure 1 and Figure 2 A base 1 is provided below the movable seat 3. The base 1 includes several splicing seats 11 and several splicing components 12. Two adjacent splicing seats 11 are aligned end to end and abut against each other. A through groove 111 is provided on the surface of the splicing seat 11 facing the base 2.

The two ends of the roller 215 are fixedly connected to the driven wheel 2151. The two driven wheels 2151 are respectively set on both sides of the travel gear 214. A transmission belt 2171 is wound between the drive wheel 2181 and the driven wheel 2151. A clearance groove 219 for the transmission belt 2171 to pass through is opened through the connecting seat 21.
[0056] refer to Figure 2 Stabilizing blocks 216 are fixed on both sides of the connecting seat 21. In this embodiment, the stabilizing blocks 216 are T-shaped blocks. The splicing seat 11 has a stabilizing groove 113 on the inner side wall of the through groove 111 that is adapted to slide with the stabilizing blocks 216. In this embodiment, the stabilizing groove 113 is a T-shaped groove.
[0057] The third drive motor 218 starts and drives the drive wheel 2181 to rotate. The drive wheel 2181 drives the driven wheel 2151 to rotate through the transmission belt 2171. The driven wheel 2151 drives the rotating roller 215 to rotate. The rotating roller 215 drives the traveling gear 214 to rotate, so the traveling gear 214 rolls along the rack 112. Thus, the traveling gear 214 drives the connecting seat 21 to slide along the through groove 111 through the rotating roller 215. During the movement of the connecting seat 21, the connecting seat 21 drives the stabilizing block 216 to slide along the stabilizing groove 113.

[0061] The operator determines the length of the limiting rod 211 based on the splicing length of the one-way screw 22. The operator then rotates the upper assembly rod 2111, causing the splicing rod 2112 to screw into the splicing hole 21111 of the lower assembly rod 2111, thus splicing the two assembly rods 2111 together. The second drive motor 212 starts, driving the active bevel gear 2121 to rotate. The active bevel gear 2121 drives the driven bevel gear 2211 to rotate, which in turn drives the one-way screw 22 to rotate. The one-way screw 22 then causes the moving seat 3 to slide along the limiting rod 211.
[0062] refer to Figure 3 , Figure 6 and Figure 7The unidirectional lead screw 22 includes several splicing lead screws 221, which are placed sequentially in a vertical direction. The top end face of the splicing lead screw 221 is provided with a mounting groove 2212.

The return spring 7143 is sleeved on the guide rod 7142.
[0065] The operator screws the mounting rod 71 of the upper splicing screw 221 into the mounting groove 2212 of the lower splicing screw 221, and then screws the trigger rod 8 into the threaded hole 2214 of the upper splicing screw 221 until the trigger rod 8 passes through the clearance hole of the upper mounting rod 71 and extends into the mounting groove 2212 of the lower splicing screw 221. At this time, the trigger rod 8 presses the limiting block 714 through the pressing surface 7141. The limiting block 714 is pressed and inserted into the limiting groove 2213. At the same time, the return spring 7143 is in a stretched state, thereby splicing the two splicing screws 221 together. When it is necessary to disassemble the two splicing screws 221, the operator rotates the trigger rod 8 by the handle 82, so that the trigger rod 8 moves away from the limit block 714. At this time, the reset spring 7143 releases its elastic force to pull the limit block 714 out of the limit groove 2213. Then the operator rotates the upper splicing screw 221 to drive the upper mounting rod 71 to rotate, thereby disassembling the two splicing screws 221.

The rotating ring 532 is rotatably connected to the fixed ring 531 away from the surface of the blade 54. The rotating ring 532 is threadedly connected to the locking rod 521.
[0071] refer to Figure 9 and Figure 10 The slide block 9 has a through hole 93 in the inner wall of the storage cavity 91. A push rod 94 is slidably connected in the through hole 93. A synchronization plate 4211 is provided between the slide block 9 and one of the supports 42. The synchronization plate 4211 is sleeved on the slide rod 421 and the two are fixedly connected. An adjusting spring 941 is fixed between the synchronization plate 4211 and the slide block 9.
[0072] refer to Figure 9 and Figure 10 The output shaft of the fourth drive motor 51, which is away from the mounting platform 52, is fixedly connected to a turntable 511. The turntable 511 is hinged to a linkage rod 5111 on the side wall away from the fourth drive motor 51. The hinge point between the linkage rod 5111 and the turntable 511 is not at the rotation center of the turntable 511. One end of the push rod 94 passes through the adjusting spring 941 and abuts against the synchronizing plate 4211. The other end of the push rod 94 is hinged to the linkage rod 5111.
[0073] The operator places the blade 54 and the clamping ring 53 onto the locking rod 521. Then, the operator rotates the rotating ring 532, which moves the fixing ring 531 closer to the mounting platform 52. The fixing ring 531 then drives the insertion rod 5311 to insert into the first insertion hole 541 and the second insertion hole 522, until the fixing ring 531 secures the blade 54. The fourth drive motor 51 starts, causing the mounting platform 52 to rotate. The mounting platform 52, through the insertion rod 5311, drives the blade 54 to rotate, thus enabling the blade 54 to cut the breast wall. Simultaneously, the fourth drive motor 51 drives the turntable 511 to rotate, and the turntable 511, through the linkage rod 5111, drives the push rod 94 to move. When push rod 94 presses against synchronous plate 4211, slide block 9 slides away from synchronous plate 421 along slide rod 421, at which time adjusting spring 941 is in a stretched state; when push rod 94 does not press against synchronous plate 4211, adjusting spring 941 releases its elastic force, causing slide block 9 to slide towards synchronous plate 4211 along slide rod 421; during the sliding process, slide block 9 drives slider to slide along slide groove. The operator starts fifth drive motor 422 to drive slide rod 421 to rotate, slide rod drives slide block 9 to rotate through slider, thereby adjusting the angle of blade 54, thus changing the cutting angle.
[0074] refer to Figure 11 The end of the drill bit away from the drill bit is hinged to the turntable 4. An adjusting rod 61 is provided between the cylinder of the drill bit 6 and the turntable 4. The adjusting rod 61 includes a fixed part 611 and a rotating part 612. The fixed part 611 is hinged to the cylinder of the drill bit 6. The rotating part 612 is rotatably connected to the fixed part 611 away from the side wall of the drill bit 6. An adjusting hole 43 is provided on the surface of the turntable 4 facing the drill bit 6 and is threadedly connected to the rotating part 612. A handwheel 6121 is fixed on the circumferential side wall of the rotating part 612.
[0075] The operator adjusts the angle between the cylinder of the drill bit 6 and the turntable 4 as needed. The operator turns the handwheel 6121 to drive the rotating part 612 to rotate, thereby adjusting the length of the rotating part 612 inserted into the adjustment hole 43, and then adjusting the angle between the cylinder of the drill bit 6 and the turntable 4, thereby adjusting the angle at which the drill bit enters the breast wall.
[0076] The implementation principle of the breast wall demolition device in this application embodiment is as follows: Workers assemble a base 1, a limiting rod 211, and a one-way screw 22 of appropriate length according to the breast wall assembly. After assembly, the connecting seat 21 moves along the length of the base 1, causing the cutting device 5 or drill 6 to move horizontally. The moving seat 3 slides along the limiting rod 211, causing the cutting device 5 or drill 6 to move vertically, thereby adjusting the position of the cutting device 5 and drill 6. Workers rotate the rotating part 612 using the handwheel 6121 to adjust the angle at which the drill bit penetrates the breast wall. Workers also use the fifth drive motor 422 to rotate the sliding rod 421, driving the sliding seat 9 to rotate, thereby adjusting the angle of the blade 54 and thus the cutting direction. This structure reduces the labor intensity of the workers.
