Description

Technical Field

[0001] This invention relates to the field of concrete rope cutting technology, specifically to a reinforced concrete rope cutting device. Background Technology

[0002] In traditional reinforced concrete structure demolition projects, mechanical demolition, cutting machines, and low-frequency pneumatic hammers are used. Mechanical demolition is suitable for complete demolition, while cutting machines and low-frequency pneumatic hammers are suitable for partial demolition. The new rope cutting method combines the advantages of all three methods, meeting construction schedule requirements while separating the demolished and retained parts as much as possible, minimizing disturbance to the structure. Using rope cutting at the connection between the top beam and the side walls improves work efficiency, ensures the safety of construction workers, and reduces environmental and noise pollution. However, existing rope cutting devices for beams have many shortcomings and cannot meet the requirements.

[0003] Traditional beam cutting devices require manual operation, which reduces work efficiency and safety to some extent. Furthermore, the cutting rope typically has abrasive beads strung on its surface. These beads contact the beam to cut it, but during the cutting process, only one side of the abrasive bead contacts the beam. When it comes into contact with the beam and the actuator, the abrasive bead's direction can easily deflect, leading to repeated contact with the beam in certain areas and resulting in uneven wear on the abrasive beads. Summary of the Invention

[0004] The purpose of this invention is to provide a reinforced concrete rope cutting device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a reinforced concrete rope cutting device, comprising a positioning component, a rope cutting component, a fixing plate, a moving platform, and positioning piles. The moving platform is set on the ground, and the positioning piles are fastened to the moving platform. Multiple sets of positioning piles are evenly distributed around the moving platform. The fixing plate is fastened to the top of the moving platform, and the side of the fixing plate away from the moving platform is fastened to the positioning component. The positioning component is connected to the rope cutting component, and two sets of rope cutting components are respectively set on both sides of the positioning component. The moving platform drives the fixing plate to move, the fixing plate drives the positioning component to move, the positioning component fixes the crossbeam, the positioning piles fix the moving platform, and the rope cutting component performs rope cutting on both ends of the crossbeam.

[0006] Furthermore, the positioning assembly includes a setting box, a contact pad, a tightening unit, and a telescopic plate. The setting box and the fixed plate are fastened together. Two sets of telescopic plates are provided, one on each side of the setting box. The rope cutting assembly and the movable end of the telescopic plate are fastened together. The contact pad and the upper surface of the setting box are fastened together. The tightening unit is connected to the setting box. The contact pad supports the bottom of the crossbeam, and the winding unit surrounds and fixes the crossbeam. The telescopic plate has an extension mechanism inside, which can adjust the extension amount according to the length of the crossbeam to ensure that the rope cutting assembly can be located at both ends of the crossbeam. The extension mechanism is a conventional technical means in this field, and its specific structure will not be described.

[0007] Furthermore, the tightening unit includes a take-up column, a winding rope, an arc-shaped tube, locking rings, locking grooves, and buckles. The take-up column is located inside the setting box and is equipped with a power mechanism. The winding rope is double-stranded, with different locking rings fixed to the ends of the two strands. One locking ring is securely connected to the locking groove, and the other locking ring is securely connected to the buckle. An arc-shaped slide is located inside the setting box, and the arc-shaped tube is securely connected to the arc-shaped slide. An ejection mechanism is located inside the arc-shaped slide. There are two sets of arc-shaped tubes and arc-shaped slides, which are arranged opposite to each other. The ejection mechanism controls the extension and retraction of the arc-shaped tube. The ejection mechanism is a conventional technical means in this field, and its specific structure will not be described. When the two sets of arc-shaped tubes are pushed out, they drive the locking rings to move. The locking rings pull the winding rope out, and after the locking grooves and buckles engage, the arc-shaped tubes retract again. The winding rope passes through the inside of the arc-shaped tubes and is wound up at the winding post. The winding post tightens the winding rope, and the crossbeam is fixed by the winding rope. The tightening unit of this invention achieves automatic fixing of the high-point crossbeam and can automatically adjust the winding size of the burning rope according to the size of the crossbeam, greatly improving the stability of the rope cutting process. On the other hand, the operation steps of this tightening unit are simple. It can be automatically locked remotely during fixing, and after the crossbeam is cut and transferred, it is only necessary to manually unlock the buckles and locking grooves to quickly transfer the crossbeam, greatly improving the working efficiency of the rope cutting device.

[0008] Furthermore, the rope cutting assembly includes a rotating disk, a control motor, adjusting rods, sliders, a lifting chamber, and a setting chamber. The setting chamber is securely connected to the telescopic plate. Two sets of adjusting rods are provided, with sliders on both sides. The lifting chamber and the setting chamber are slidably connected. One end of the adjusting rod is slidably connected to the lifting chamber, and the other end is slidably connected to the setting chamber. A rotating disk is located at the center of the two sets of adjusting rods, and the adjusting rods are rotatably connected to the rotating disk. The output shaft of the control motor is securely connected to the center of one set of adjusting rods. A sliding track is provided on the side wall of the setting chamber, and the control motor is slidably connected to the sliding track. The control motor drives the adjusting rods to rotate, adjusting the angle between the two sets of adjusting rods. When the angle widens, the sliders move to the sides, and the lifting chamber descends. When the angle narrows, the sliders converge towards the center, and the lifting chamber rises. The lifting chamber tightens the cutting rope by moving up and down, facilitating the cutting of the crossbeam.

[0009] Furthermore, the lifting chamber is internally equipped with an annular tube, a cutting rope, a driver, an adjusting block, and an extension tube. The annular tube, driver, and lifting chamber are fastened together. The adjusting block is located at the output end of the driver. There are two sets of annular tubes: one set is connected to the output end of the driver, and the other set is connected to the end of the adjusting block away from the driver. There are also two sets of extension tubes, each slidably connected to an annular tube. A displacement mechanism is installed inside the annular tube to control the extension amount of the extension tube. A fixing clamp is installed on the side of the extension tube away from the annular tube. The cutting rope passes through the driver, adjusting block, annular tube, and extension tube in sequence. Connecting buckles are installed at both ends of the cutting rope. The adjusting block is internally equipped with an airflow chamber, a transition hole, an air inlet, and an exhaust hole. The transition hole is located inside the airflow chamber, through which the cutting rope passes. The air inlet is located on the lower side of the airflow chamber, and the exhaust hole is located on the upper side of the airflow chamber. The air inlet is connected to an external air supply channel. The cutting rope extends from two extension tubes at both ends. A fixing clamp holds the cutting rope in place, and a displacement mechanism inside the annular tube pushes the extension tubes out. When the two extension tubes align, the connecting buckle of the cutting rope automatically engages. The fixing clamp and displacement mechanism are conventional techniques in this field, and their specific structures are not described. A driver drives the cutting rope to rotate cyclically. The driver is also a conventional technique in this field, and its specific structure is not described. Polishing beads are strung on the surface of the cutting rope. These beads contact the crossbeam, cutting it. However, during the cutting process, only one side of the polishing beads contacts the crossbeam. When in contact with the crossbeam and the driver, the direction of the polishing beads is prone to deflection, leading to repeated contact between localized areas of the polishing beads and the crossbeam, resulting in uneven wear on the polishing beads. In this invention, the polishing beads maintain a relatively stable path after leaving the adjusting block, preventing rotation. As the polishing beads pass the adjusting block, external airflow continuously enters through the air inlet and exits from both sides of the polishing beads, exiting through the exhaust port. The force of the airflow is greater than the weight of the polishing beads. For polishing beads with significant localized wear, their center of gravity shifts towards the less worn area. The airflow causes the center of gravity of the polishing bead to shift upwards, placing the less worn area at the contact point for subsequent polishing. This invention, through the adjusting block, achieves both position adjustment of the polishing beads and cooling during the polishing process.

[0010] Furthermore, the movable platform includes a support frame, casters, and a lifting unit. The lifting unit is located inside the support frame, with its bottom securely connected to the support frame and its top securely connected to a fixed plate. Four casters are located on the outside of the support frame, each mounted at one of the four corners. The casters move the support frame below the crossbeam, and the lifting unit moves the positioning assembly upwards to support the crossbeam.

[0011] Furthermore, the lifting unit includes an upper plate, a lower plate, a folding frame, and an adjusting cylinder. One side of the folding frame is securely connected to the upper plate, and the other side of the folding frame is securely connected to the lower plate. The side of the upper plate away from the folding frame is securely connected to a fixed plate, and the side of the lower plate away from the folding frame is securely connected to a support frame. The adjusting cylinder is securely connected to the lower plate, and the output shaft of the adjusting cylinder is securely connected to the folding frame. The folding frame is a conventional technology in this field, and its specific structure is not described. When the fixed plate needs to move upward, the adjusting cylinder pushes the folding frame to unfold, and the upper plate moves upward under the push of the folding frame. The fixed plate moves upward along with the upper plate, and after moving upward, the positioning assembly supports the crossbeam.

[0012] Furthermore, the positioning stake includes a setting cylinder, a fixed cone, a barb, a connecting rod, a first cylinder, and a second cylinder. The setting cylinder is fastened to the support frame, and the fixed cone is slidably connected to the setting cylinder. The first cylinder is located inside the setting cylinder and is fastened to it. The output shaft of the first cylinder is fastened to the fixed cone. The second cylinder is located inside the fixed cone, and the barb is hinged to the fixed cone. One end of the connecting rod is hinged to the side of the barb away from the fixed cone, and the other end of the connecting rod is hinged to the output shaft of the second cylinder. With the bottom of the setting cylinder facing the ground, the first cylinder pushes the fixed cone out, and the fixed cone inserts into the ground. At this time, the second cylinder pushes the connecting rod, and the connecting rod pushes the barb out to both sides. The barb pulls the fixed cone tight, preventing the fixed cone from detaching from the ground.

[0013] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: The tightening unit of this invention achieves automatic fixation of the high-point crossbeam and can automatically adjust the wrapping size of the burning rope according to the size of the crossbeam, greatly improving the stability of the rope cutting process. On the other hand, the operation steps of this tightening unit are simple. It can be automatically fastened remotely during fixation. After the crossbeam is cut and transferred, it is only necessary to manually unfasten the buckles and slots to quickly transfer the crossbeam, greatly improving the working efficiency of the rope cutting device. When the polishing ball of this invention leaves the adjusting block, the subsequent path is relatively stable and it is not easy to rotate. When the polishing ball passes the adjusting block, the external airflow continuously enters from the air inlet and exits from both sides of the polishing ball and is discharged from the exhaust port. The force of the airflow is greater than the weight of the polishing ball. For polishing balls with large local wear, their center of gravity shifts to the position where there is no large wear. The effect of the airflow will cause the center of gravity of the polishing ball to shift upward, and the position of the polishing ball where there is no large wear will be located at the contact position of subsequent polishing. This invention uses an adjusting block to both adjust the position of the polishing beads and cool down the polishing process. Attached Figure Description

Detailed Implementation

[0015] 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.

[0016] like Figure 1As shown, a reinforced concrete rope cutting device includes a positioning component 1, a rope cutting component 2, a fixing plate 3, a moving platform 4, and positioning piles 5. The moving platform 4 is set on the ground, and the positioning piles 5 are fastened to the moving platform 4. Multiple sets of positioning piles 5 are evenly distributed around the moving platform 4. The fixing plate 3 is fastened to the top of the moving platform 4, and the side of the fixing plate 3 away from the moving platform 4 is fastened to the positioning component 1. The positioning component 1 is connected to the rope cutting component 2, and two sets of rope cutting components 2 are set on both sides of the positioning component 1. The moving platform 4 drives the fixing plate 3 to move, and the fixing plate 3 drives the positioning component 1 to move. The positioning component 1 fixes the crossbeam, the positioning piles 5 fix the moving platform 4, and the rope cutting component 2 performs rope cutting on both ends of the crossbeam.

[0017] like Figure 1 As shown, the positioning component 1 includes a setting box 11, a contact pad 12, a tightening unit 13, and a telescopic plate 14. The setting box 11 and the fixing plate 3 are fastened together. Two sets of telescopic plates 14 are provided, with the two sets of telescopic plates 14 respectively located on both sides of the setting box 11. The rope cutting component 2 is fastened to the movable end of the telescopic plate 14. The contact pad 12 is fastened to the upper surface of the setting box 11. The tightening unit 13 is connected to the setting box 11. The contact pad 12 supports the bottom of the crossbeam, and the winding unit 13 surrounds and fixes the crossbeam. The telescopic plate 14 is provided with an extension mechanism, which can adjust the extension amount according to the length of the crossbeam to ensure that the rope cutting component 2 can be located at both ends of the crossbeam. The extension mechanism is a conventional technical means in this field, and its specific structure is not described.

[0018] like Figure 5As shown, the tightening unit 13 includes a winding post 131, a winding rope 132, an arc-shaped tube 133, a locking ring 134, a locking groove 135, and a buckle 136. The winding post 131 is located inside the setting box 11 and is equipped with a power mechanism. The winding rope 132 is double-stranded, and different locking rings 134 are fixed to the ends of the two strands of the winding rope 132. One locking ring 134 is fastened to the locking groove 135, and the other locking ring 134 is fastened to the buckle 136. An arc-shaped slide is provided inside the setting box 11, and the arc-shaped tube 133 is fastened to the arc-shaped slide. An ejection mechanism is provided inside the arc-shaped slide. There are two sets of arc-shaped tubes 133 and arc-shaped slides, and the two sets of arc-shaped tubes 133 and arc-shaped slides are arranged opposite to each other. The ejection mechanism can control the ejection and retraction of the arc-shaped tube 133. The ejection mechanism is a conventional technical means in this field, and its specific structure is not described. When the two sets of arc-shaped tubes 133 are pushed out, they drive the locking ring 134 to move. The locking ring 134 pulls the winding rope 132 outward. After the locking groove 135 and the buckle 136 are engaged, the arc-shaped tube 133 retracts again, and the winding rope 132 passes through the inside of the arc-shaped tube 133 and is wound up at the winding post 131. The winding post 131 tightens the winding rope 132, and the crossbeam is fixed by the winding rope 132. The tightening unit 13 of the present invention realizes the automatic fixation of the high point crossbeam and can automatically adjust the winding size of the burning rope according to the size of the crossbeam, which greatly improves the stability of the rope cutting process. On the other hand, the operation steps of the tightening unit are simple. It can be automatically engaged remotely during fixation. After the crossbeam is cut and transferred, it is only necessary to manually unfasten the buckle and the locking groove to quickly transfer the crossbeam, which greatly improves the working efficiency of the rope cutting device.

[0019] like Figure 6 , Figure 7 As shown, the rope cutting assembly 2 includes a rotating disk 21, a regulating motor 22, an adjusting rod 23, a slider 24, a lifting chamber 25, and a setting chamber 26. The setting chamber 26 is fastened to the telescopic plate 14. There are two sets of adjusting rods 23, with sliders on both sides of the adjusting rods 23. The lifting chamber 25 and the setting chamber 26 are slidably connected. The slider 24 at one end of the adjusting rod 23 is slidably connected to the lifting chamber 25, and the slider 24 at the other end of the adjusting rod 23 is slidably connected to the setting chamber 26. A rotating disk 21 is located at the center of the two sets of adjusting rods 23, and the adjusting rods 23 and the rotating disk 21 are rotatably connected. The output shaft of the regulating motor 22 is fastened to the center of one set of adjusting rods 23. A sliding track is provided on the side wall of the setting chamber 26, and the regulating motor 22 is slidably connected to the sliding track. The control motor 22 drives the adjustment rod 23 to rotate, thereby adjusting the angle between the two sets of adjustment rods 23. When the angle widens, the slider 24 moves to both sides and the lifting chamber 25 descends. When the angle narrows, the slider 24 converges to the center and the lifting chamber 25 moves upward. The lifting chamber 25 tightens the cutting rope 252 by moving up and down, so as to facilitate the cutting of the crossbeam.

[0020] like Figure 6 , Figure 7 , Figure 8 As shown, the lifting chamber 25 is internally equipped with an annular tube 251, a cutting rope 252, a driver 253, an adjusting block 254, and an extension tube 255. The annular tube 251, the driver 253, and the lifting chamber 25 are fastened together. The adjusting block 254 is located at the output end of the driver 253. There are two sets of annular tubes 251. One set of annular tubes 251 is connected to the output end of the driver 253, and the other set of annular tubes 251 is connected to the end of the adjusting block 254 away from the driver 253. There are two sets of extension tubes 255. The two sets of extension tubes 255 are slidably connected to the annular tubes 251 respectively. A displacement mechanism is installed inside the annular tube 251, which controls the extension tube. The extension of tube 255 is such that a fixing clip is provided on the side of the extension tube 255 away from the annular tube 251. The cutting rope 252 passes through the inside of the driver 253, the adjusting block 254, the annular tube 251, and the extension tube 255 in sequence. The two ends of the cutting rope 252 are provided with connecting buckles. The adjusting block 254 is provided with an airflow chamber 2541, a transition hole 2542, an air inlet 2543, and an exhaust hole 2544. The transition hole 2542 is located inside the airflow chamber 2541. The cutting rope 252 passes through the transition hole 2542. The air inlet 2543 is located on the lower side of the airflow chamber 2541, and the exhaust hole 2544 is located on the upper side of the airflow chamber 2541. The air inlet 2543 is connected to the external air supply channel. The cutting rope 252 extends from two extension tubes 255 at both ends. A fixing clamp holds the cutting rope 252 in place. A displacement mechanism inside the annular tube 251 pushes the extension tubes 255 outwards. When the two extension tubes 255 align, the connecting buckle of the cutting rope 252 automatically engages. The fixing clamp and displacement mechanism are conventional techniques in this field, and their specific structures are not described. The driver 253 drives the cutting rope 252 to rotate cyclically. The driver is also a conventional technique in this field, and its specific structure is not described. Polishing beads are strung on the surface of the cutting rope 252. These beads contact the crossbeam and cut it. However, during the cutting process, only one side of the polishing bead contacts the crossbeam. When in contact with the crossbeam and the driver, the direction of the polishing beads is prone to deflection, leading to repeated contact between localized areas of the polishing beads and the crossbeam, resulting in uneven wear on the polishing beads. In this invention, the polishing bead maintains a relatively stable path after leaving the adjusting block 254, preventing rotation. As the polishing bead passes the adjusting block, external airflow continuously enters through the air inlet and exits from both sides of the polishing bead, exiting through the exhaust port 2544. The force of the airflow is greater than the weight of the polishing bead. For polishing beads with significant localized wear, their center of gravity shifts towards the less worn area. The airflow causes the center of gravity of the polishing bead to shift upwards, ensuring that the less worn area is at the contact point for subsequent polishing. This invention, through the adjusting block 254, achieves both position adjustment of the polishing bead and cooling during the polishing process.

[0021] like Figure 1 , Figure 2 As shown, the movable platform 4 includes a support frame 41, movable wheels 42, and a lifting unit 43. The lifting unit 43 is located inside the support frame 41, with its bottom and top securely connected to the support frame 41 and the fixed plate 3, respectively. Four movable wheels 42 are located on the outside of the support frame 41, installed at the four corners of the support frame 41. The movable wheels 42 can move the support frame 41 to below the crossbeam, and the lifting unit 43 moves the positioning component 1 upward to support the crossbeam.

[0022] like Figure 2 As shown, the lifting unit 43 includes an upper plate 431, a lower plate 432, a folding frame 433, and an adjusting cylinder 434. One side of the folding frame 433 is fastened to the upper plate 431, and the other side of the folding frame 433 is fastened to the lower plate 432. The side of the upper plate 431 away from the folding frame 433 is fastened to the fixed plate 3, and the side of the lower plate 432 away from the folding frame 433 is fastened to the support frame 41. The adjusting cylinder 434 is fastened to the lower plate 432, and the output shaft of the adjusting cylinder 434 is fastened to the folding frame 433. The folding frame 433 is a conventional technology in this field, and its specific structure is not described. When the fixed plate 3 needs to be moved upward, the adjusting cylinder 434 pushes the folding frame 433 to unfold. The upper plate 431 moves upward under the push of the folding frame 433, and the fixed plate 3 moves upward along with the upper plate 431. After moving upward, the positioning component 1 supports the crossbeam.

[0023] like Figure 3 , Figure 4 As shown, the positioning pile 5 includes a setting cylinder 51, a fixing cone 52, a barb 53, a connecting rod 54, a first cylinder 55, and a second cylinder 56. The setting cylinder 51 is fastened to the support frame 41, and the fixing cone 52 is slidably connected to the setting cylinder 51. The first cylinder 55 is located inside the setting cylinder 51 and is fastened to the setting cylinder 51. The output shaft of the first cylinder 55 is fastened to the fixing cone 52. The second cylinder 56 is located inside the fixing cone 52, and the barb 53 is hinged to the fixing cone 52. One end of the connecting rod 54 is hinged to the side of the barb 53 away from the fixing cone 52, and the other end of the connecting rod 54 is hinged to the output shaft of the second cylinder 56. With the bottom of the setting cylinder 51 facing the ground, the first cylinder 55 pushes the fixing cone 52 out, and the fixing cone 52 inserts into the ground. At this time, the second cylinder 56 pushes the connecting rod 54, and the connecting rod 54 pushes the barb 53 out to both sides. The barb 53 pulls the fixing cone 52 tight, preventing the fixing cone 52 from leaving the ground.

[0024] The working principle of this invention is as follows: The moving wheel 42 can drive the support frame 41 to move below the crossbeam. The adjusting cylinder 434 pushes the folding frame 433 to unfold. The upper plate 431 moves upward under the push of the folding frame 433. The fixed plate 3 moves upward with the upper plate 431. After moving upward, the positioning component 1 supports the crossbeam. The first cylinder 55 pushes the fixed cone 52 to extend. The fixed cone 52 inserts into the ground. At this time, the second cylinder 56 pushes the connecting rod 54. The connecting rod 54 pushes the barb 53 to both sides. The barb 53 pulls the fixed cone 52 tight to prevent the fixed cone 52 from leaving the ground. The contact pad 12 supports the bottom of the crossbeam. The winding unit 13 surrounds and fixes the crossbeam. The telescopic plate 14 is provided with a push-out mechanism, which can adjust the telescopic amount according to the length of the crossbeam to ensure that the rope cutting component 2 can be located at both ends of the crossbeam. The cutting rope 252 extends from two extension tubes 255 at both ends. The fixing clamp holds the cutting rope 252. The displacement mechanism inside the annular tube 251 pushes the extension tubes 255 to extend. The two extension tubes 255 are aligned, and the connecting buckle of the cutting rope 252 is automatically engaged. The driver 253 drives the cutting rope 252 to rotate cyclically. The cutting rope cuts the crossbeam. During the cutting process, the polishing ball will continuously pass through the adjusting block. External airflow will continuously enter from the air inlet and exit from both sides of the polishing ball and exit from the exhaust port 2544. The force of the airflow is greater than the weight of the polishing ball. For polishing balls with large local wear, their center of gravity will shift to the position where there is no large wear. The action of the airflow will cause the center of gravity of the polishing ball to shift upward. The position of the polishing ball where there is no large wear will be the contact position for subsequent polishing.
