Description

Technical Field

[0001] This application relates to the field of bridge demolition technology, and in particular to a bridge integral cutting wire saw device. Background Technology

[0002] In bridge reconstruction, demolition, or repair projects, precise cutting of the bridge's main structure (such as piers and beams) is a crucial step. Traditional methods such as mechanical crushing and blasting not only generate significant vibration and noise but also easily cause secondary damage to surrounding structures, failing to meet the requirements of modern engineering for construction precision and environmental protection. Bridge integral cutting wire saws, with their high cutting precision, low vibration, low noise, and adaptability to complex structural cutting, are gradually becoming the mainstream equipment in bridge structural cutting construction.

[0003] Existing bridge integral cutting wire saw devices typically consist of a drive mechanism, guide wheel assembly, diamond wire saw, tensioning device, and frame. The drive mechanism provides power for the cyclical movement of the wire saw, while the guide wheel assembly is used to change the direction of the wire saw's movement, enabling it to conform to the contour of the section of the bridge to be cut.

[0004] Regarding the aforementioned technologies, the inventors believe that when a wire saw cuts structures such as bridge piers to a certain extent, the distance between the part to be cut and the cutting equipment gradually shortens. The originally taut cutting wire becomes relatively slack due to this change in spatial distance, resulting in reduced cutting efficiency. This often necessitates stopping the machine and readjusting the equipment position to restore the wire saw's tautness, which not only interrupts the construction process but also increases operating time and labor costs, severely impacting overall construction efficiency. Utility Model Content

[0005] The purpose of this application is to provide a bridge integral cutting wire saw device to improve the problem of increased operation time and labor costs due to downtime and readjustment of equipment position to restore the wire saw to a taut state, which affects the overall construction efficiency.

[0006] This application provides a wire saw device for integral bridge cutting, which adopts the following technical solution:

[0007] A bridge integral cutting wire saw device includes a base plate, a driving component is provided on the top surface of the base plate, a threaded rod is provided at the output end of the driving component along the length direction of the base plate, and a fixed seat is provided at the end of the base plate away from the driving component on the threaded rod; a sliding plate is threadedly connected to the threaded rod, a main unit is provided on the top surface of the sliding plate, a drive wheel is provided on one side of the main unit, a cutting rope is provided on the drive wheel, and a fixed pulley tangent to the cutting rope is rotatably provided on the same side of the main unit as the drive wheel.

[0008] By adopting the above technical solution, the drive component drives the threaded rod to rotate, which in turn causes the threaded sliding plate to move the main unit along the length of the base plate. When the cutting rope becomes slack due to the shortened distance between the part to be cut and the equipment, the entire equipment can be tightened without stopping the machine or moving the whole equipment. The cutting rope can be tightened simply by adjusting the position of the main unit. This effectively avoids a decrease in cutting efficiency, reduces downtime and adjustment time and labor costs, and ensures the continuity of the construction process.

[0009] Optionally, the bottom surface of the base plate is provided with a set of movable wheels, and the end of the bottom surface of the base plate away from the movable wheels is provided with a plug to facilitate fixing the base plate.

[0010] By adopting the above technical solution, the movable wheels on the bottom of the base plate make it easy for the device to be moved flexibly to the working position, saving the effort and time of transporting the equipment; while the insertion rod at the end away from the movable wheels can be inserted into the ground after the device reaches the designated position, and cooperate with the movable wheels to achieve stable fixation of the device, ensuring the stability and safety of the cutting operation.

[0011] Optionally, the base plate is provided with grooves on both sides of the threaded rod along its length, and the bottom surface of the slide plate is provided with a slider corresponding to the groove.

[0012] By adopting the above technical solution, the sliding groove and the slider cooperate to provide guidance and limit for the movement of the slide plate, so that the slide plate can move smoothly and accurately along the length of the base plate under the drive of the threaded rod.

[0013] Optionally, a telescopic drive component is provided on one side of the main unit between the drive wheel and the fixed pulley in the vertical direction. A movable block is provided at the output end of the telescopic drive component, and a tensioning wheel that abuts against the cutting rope is rotatably provided on one side of the movable block.

[0014] By adopting the above technical solution, when the cutting rope shows signs of slack, the tensioning wheel can promptly engage with the cutting rope and apply pressure. Combined with the adjustment of the main unit position, this further enhances the tensioning effect on the cutting rope, helps the cutting rope maintain appropriate tension, improves the stability and accuracy of cutting, and reduces cutting deviations caused by the slack of the cutting rope.

[0015] Optionally, both the tensioning wheel and the fixed pulley have corner grooves on their outer side walls.

[0016] By adopting the above technical solution, the corner groove can limit the cutting rope, which helps to prevent the cutting rope from falling off the tensioning wheel or fixed pulley during high-speed movement, ensuring the smooth progress of the cutting operation, and reducing equipment damage and safety hazards caused by the cutting rope falling off.

[0017] Optionally, the main unit is rotatably mounted above the fixed pulley, with a pressure roller that cooperates with the fixed pulley to clamp the cutting rope.

[0018] By adopting the above technical solution, the pressure roller above the fixed pulley works in conjunction with the fixed pulley to clamp the cutting rope, which can increase the friction between the cutting rope and the fixed pulley and prevent the cutting rope from slipping during the movement.

[0019] Optionally, a fixing plate is provided on one side of the main unit, and the fixing plate is provided with a fixing ring for the cutting rope, and a brush is provided on the inner side wall of the fixing ring to clean the cutting rope.

[0020] By adopting the above technical solution, the brush can clean the debris attached to the surface during the movement of the cutting rope, reduce the debris entering the drive wheel and affecting its normal operation, reduce the wear of the drive wheel, extend the service life of the equipment, and at the same time ensure the cleanliness of the cutting rope, which is conducive to maintaining the cutting effect.

[0021] Optionally, the fixing ring is provided with a plurality of fixing bolts that are threadedly connected to the fixing plate.

[0022] By adopting the above technical solution, the fixing ring is fixed by fixing bolts that are threadedly connected to the fixing plate, which makes it easy to replace the fixing ring and maintain the cleaning effect of the brush.

[0023] In summary, this application includes at least one of the following beneficial technical effects of the bridge integral cutting wire saw device:

[0024] 1. By driving the threaded rod to rotate through the drive component, the threaded sliding plate moves the main unit along the length of the base plate. When the cutting rope becomes slack due to the shortened distance between the part to be cut and the equipment, the entire equipment can be tightened without stopping the machine or moving the whole equipment. The cutting rope can be tightened simply by adjusting the position of the main unit. This effectively avoids a decrease in cutting efficiency, reduces downtime and adjustment time and labor costs, and ensures the continuity of the construction process.

[0025] 2. When the cutting rope shows signs of slack, the tensioning wheel can promptly engage with the cutting rope and apply pressure. Combined with the adjustment of the main unit position, this further enhances the tensioning effect on the cutting rope, helps the cutting rope maintain appropriate tension, improves the stability and accuracy of cutting, and reduces cutting deviations caused by the slack of the cutting rope.

[0026] 3. The brush can clean the debris attached to the surface during the movement of the cutting rope, reducing the amount of debris entering the drive wheel and affecting its normal operation, reducing the wear of the drive wheel, extending the service life of the equipment, and also ensuring the cleanliness of the cutting rope, which is conducive to maintaining the cutting effect.

The plug rod 61 is made of metal and has a tapered lower end to facilitate insertion into the ground to fix the base plate 1.

[0032] Reference Figure 1 , Figure 2 A drive component 2, which is a servo motor, is fixed to the top surface of the base plate 1 by bolts. The output end of the drive component 2 is connected to a threaded rod 21 along the length of the base plate 1 via a coupling. A fixed seat 22 is welded to the end of the base plate 1 away from the drive component 2 at the end of the threaded rod 21. The end of the threaded rod 21 away from the drive component 2 is rotatably connected to the fixed seat 22 via a bearing. A sliding plate 3 is threadedly connected to the threaded rod 21. Slide grooves 11 are formed on both sides of the threaded rod 21 along its length on the base plate 1. A slider 31 is integrally formed on the bottom surface of the sliding plate 3 corresponding to the slide grooves 11. The slider 31 slides with the slide grooves 11, so that the sliding plate 3 can move stably along the length of the base plate 1.

[0033] Reference Figure 1 , Figure 2 The main unit 4 is fixed to the top surface of the slide plate 3 by bolts. The main unit 4 is the main control part of the wire saw cutting equipment and has internal control circuits, etc. A drive wheel 41 is fixed to one side of the main unit 4 by bolts. The drive wheel 41 is connected to the drive mechanism inside the main unit 4 and can be driven to rotate. A cutting rope 42 is wound on the drive wheel 41. The cutting rope 42 is a diamond wire saw and is the main execution part of the cutting operation. On the same side of the main unit 4 as the drive wheel 41, a fixed pulley 5 is rotatably mounted on the main unit 4 through a bearing and is tangent to the cutting rope 42. Above the fixed pulley 5, a pressure roller 8 is rotatably mounted on the main unit 4 through a bearing to cooperate with the fixed pulley 5 to clamp the cutting rope 42.

[0034] Reference Figure 1 , Figure 2 A telescopic drive component 7 is bolted to one side of the main unit 4 between the drive wheel 41 and the fixed pulley 5 in the vertical direction. The telescopic drive component 7 is a hydraulic cylinder that can achieve stable telescopic movement. A moving block 71 is bolted to the output end of the telescopic drive component 7. A tensioning wheel 72 is rotatably mounted on one side of the moving block 71 via a bearing, which abuts against the cutting rope 42. Angle grooves 51 are provided on the outer walls of both the tensioning wheel 72 and the fixed pulley 5.

[0036] The implementation principle of this application embodiment is as follows:

[0037] In actual use, first push the device to the designated position, then insert the conical rod 61 into the ground fixed base plate 1, and wrap the cutting rope 42 around the area to be cut, sequentially winding around the drive wheel 41, passing between the fixed pulley 5 and the pressure wheel 8, and around the tension wheel 72 and the fixed ring 91 to form a closed loop and test the motion state; during cutting, the tension wheel 72 driven by the hydraulic cylinder can be dynamically adjusted according to the tension change of the cutting rope 42. When the cutting rope 42 is slack, the drive component 2 drives the threaded rod 21 to rotate, so that the slide plate 3 moves along the slide groove 11 to adjust the distance between the host 4 and the part to be cut to tighten the cutting rope 42. At the same time, the brush 911 in the fixed ring 91 cleans the debris of the cutting rope 42. The fixed pulley 5 and the pressure wheel 8 cooperate to guide the direction, which significantly improves the construction efficiency.
