Description

Technical Field

[0001] This disclosure relates to the technical field of cable-stayed bridge cable lifting and hoisting equipment, and in particular to a height-adaptive cable-stayed bridge installation lifting and hoisting device. Background Technology

[0002] When installing and fixing the cables of a cable-stayed bridge, it is often necessary to use cable-stayed bridge cable lifting and hoisting equipment to lift and hoist the cables to be installed.

[0003] Patent application CN202610151705.64 discloses a hoisting device and method for installing bridge railings. The railing is placed on a support block on a vehicle body at the end furthest from the drive unit, with the railing mesh resting on the support block. A connecting piece is engaged between the baffle and the support block. A pushing assembly moves the railing towards one end of the drive unit. A second motor drives a second screw to rotate, causing a pusher block to move along the second screw. The pusher block moves the railing. When a first photoelectric sensor detects that the connecting hole is directly above it, the second motor stops rotating and rotates in the opposite direction, causing the pusher block to return to its original position. At the front position, the vehicle moves along the bridge body. When the second photoelectric sensor is blocked by the second bolt, the vehicle stops moving. The gripping device grabs a guardrail on the support block and moves it to the edge of the bridge body under the action of the drive device. Then the guardrail is lowered. At this time, the first bolt is inserted into the connecting hole and the second bolt is inserted into the connecting piece. The worker in the basket body screws the nut into the second bolt, and the worker on the operating plate screws the nut into the first bolt. This can efficiently install the guardrail and requires less manual labor throughout the process, making it easier for workers to operate. It can also efficiently install large-sized and heavy guardrails. Furthermore, the guardrail is connected to both the upper surface and sides of the bridge structure, making the installation more stable and facilitating later disassembly and maintenance. Patent application CN202310641679.1 discloses a hoisting device and method for the main beam of a cable-stayed bridge. After the lifting frame completes the hoisting at the pier top, it can lift the standard section of the main beam, converted by the steel beam conversion platform, onto the beam transport trolley, replacing the traditional bridge deck crane used at the pier top during construction. This reduces the occupation of construction machinery and lowers machinery rental costs. The temporary steel beam connection is set at the top of the lower crossbeam, enabling the connection between the main beam at the pier top and the lower crossbeam. The crossbeams are temporarily fixed together. The minimum unit for using vertical jacks is a pair. When using vertical jacks to jack up the two sections of the main longitudinal beam at the top of the pier, calculations show that if the jacks are not fully raised, they should be lowered in multiple stages. During the jacking process, temporary supports are used to convert the system, facilitating the jacking back. The lifting frame device used has high construction efficiency. The original construction method used a tower crane to hoist the main beam at the top of the pier, but this required suspending the tower column construction on site. Before the crossbeam construction on the tower column, the main beam at the top of the pier, the bridge deck, and the bridge deck crane needed to be installed, which severely restricted the construction period. By designing and processing the lifting frame device, the installation of the main beam at the top of the pier is not affected by the construction of the upper crossbeam.

[0004] According to its publicly available technical solutions, existing cable-stayed bridge lifting and hoisting equipment has several drawbacks. First, it cannot effectively guarantee the stability of the cable-stayed bridge during lifting operations. Strong winds can cause significant swaying during lifting, compromising construction safety. Second, there is a risk of cable falls during installation, hindering safe installation. Third, if a cable falls, insufficient clamping force between the locking structure and the cable can cause it to slip. Furthermore, the cable is prone to deformation under pressure, making it difficult to lock effectively, thus compromising the locking process. Summary of the Invention

The tilting block and the misaligned sliding object are clamped to one side of the inner frame under the pressure of the powerful resetter. The outer side of the inner frame is welded with a liquid discharge tank, a Tesla baffle, and a differential channel. The hydraulic oil in the liquid discharge tank flows through the differential channel at the bottom of the Tesla baffle, allowing for forward and reverse flow. An oil extrusion round profile is welded to the misaligned sliding object. The oil extrusion round profile inhibits the reset of the misaligned sliding object on the inner side of the liquid discharge tank. Guided by the inclined sliding surface at the top of the tilting block, the anti-reverse guardrail locks the falling bridge cable.

The self-detaching unit includes two motors, two screw rods, and two support sleeves. A vertical guide unit is connected to the support sleeves. The vertical guide unit includes a movable bracket, a fixed wheel, and a pressure sleeve. The two motors drive the screw rods to move the movable bracket and the pressure sleeve in the limited direction of the support sleeves.

The rotary control console is bolted to the top of the tower crane base column, and the rigid cross brace is bolted to the rotary control console. Both ends of the rigid cross brace pass through the rotary control console. A winch and a counterweight are provided at one end of the rigid cross brace. The counterweight drives the winch to move at one end of the rigid cross brace via a slide rail. A power unit and a lead screw are installed at the top of one end of the rigid cross brace. The power unit pushes the counterweight to move laterally via the lead screw.

[0012] Optionally, a trolley and a pulley block are installed at the other end of the rigid cross brace. The pulley block is bolted to the bottom of the trolley, and the trolley drives the pulley block to move horizontally at the other end of the rigid cross brace. One end of the pulley block is connected to the inside of the winch, and the fixed frame is connected to the bottom of the pulley block through a load-bearing rod. The winch lifts the fixed frame and the load-bearing rod by winding the steel rope on the pulley block.

[0013] Optionally, the inner side of the inner fitting structure is provided with an inner cavity and a sliding groove. The sliding groove is distributed at both ends of the inner cavity. One side of the misaligned sliding object and the skewed block is locked on the inner wall of one side of the sliding groove.

[0016] Optionally, one end of the extrusion round profile is integrally formed on the other side of the skewed block, and the other end of the extrusion round profile is secured to the inner wall of the liquid slow discharge tank by a sealing ring. The distance between the extrusion round profile and the Tesla stop mechanism is equal to the width of the misaligned sliding object.

[0017] The technical solution provided in this disclosure may include the following beneficial effects: In operation, a ship transports the tower crane base, rotating control console, strong cross braces, and fixed frame to the installation platform at the bridge pier of the cable-stayed bridge. A ship-mounted hydrogeological survey winch is then used to place these structures one by one onto the platform. The winch's operation, involving raising and lowering, secures the structures. During operation, the rotating control console rotates the strong cross braces at the top of the tower crane base. The overhead crane moves the fixed frame and load-bearing rods via pulley blocks. The winch, also via pulley blocks, raises and lowers the fixed frame and load-bearing rods. Simultaneously, the power unit drives the counterweight via a lead screw, which in turn moves the winch. This system ensures constant stability of the center of gravity, allowing for continuous maintenance of the fixed frame. The frame is hoisted to the bridge frame of the cable-stayed bridge where the cables need to be installed. The position of the fixed frame on the bridge frame is adjusted according to the installation position of the cables. Then, the drive machine is turned on. The drive machine drives the screw rod to move the screw sleeve inside the rib sleeve, which in turn drives the clamping plate to clamp and fix the fixed frame on the bridge frame. At the same time, the clamping force of the clamping plate and the pulling force of the pulley block are used to fix the fixed frame. When lifting and lowering the fixed frame, the clamping plate, rib sleeve and fixed frame can be used to move and lower it on the outside of the bridge frame. This can effectively prevent swaying due to slightly strong winds during the lifting operation of the cable-stayed bridge, thus ensuring the construction safety of the cable-stayed bridge installation operation.

[0018] In use, after the fixed frame is locked onto the cable tray, the bottom end of the flexible rope is tied to the cable. The flexible rope is then wound up by a winding machine to lift the cable upwards. The flexible rope is limited by the movable support and the inner clamping mechanism to prevent swaying. The cable is moved between the movable support and the inner clamping mechanism, with one side of the cable pressed against the right side of the fixed pulley and the other side pressed against the left side of the anti-reverse retainer. The anti-reverse retainer pushes the misaligned sliding object, which pushes the tilted block through the inclined sliding surface. This causes both the misaligned sliding object and the tilted block to compress the powerful resetter and move to the left until the fixed pulley and the anti-reverse retainer... The spacing of the guardrails allows the bridge cable to pass through. The bottom of the vertical weight barrier is pressed against the top of the anti-reverse guardrail by the elastic force of the equal-diameter screw feeder. This allows the anti-reverse guardrail to rotate counterclockwise, so that the forward and reverse convex can be smoothly pushed open by the stop concave and quickly locked into the inner side of the next stop concave. Once there is a risk of the bridge cable falling during the installation of the bridge cable, the forward and reverse convex can be effectively used to lock the stop concave. At the same time, the vertical guide device is used to keep the vertical weight barrier from moving in the horizontal direction. Thus, the anti-reverse guardrail and the fixed wheel can be used to lock the bridge cable, prevent the bridge cable from falling, and ensure the safe installation of the bridge cable.

[0019] During use, when the misaligned sliding object and the skewed block move to the left, they drive the extrusion round profile to move towards the inside of the liquid discharge tank. The extrusion round profile smoothly squeezes the hydraulic oil on the right side of the liquid discharge tank through the reverse channel at the bottom of the Tesla block to the left side of the liquid discharge tank. When the bridge cable deforms under pressure due to its own material properties, the downward tension of the bridge cable on the anti-reverse guardrail causes the anti-reverse guardrail to drive the misaligned sliding object to slide to the right and downward on the top of the skewed block via the inclined sliding surface. The vertical pressure barrier moves downward under the pressure of the equal-diameter screw feeder and inserts into the inside of the stop recess in real time through the reverse anti-reverse convex, thus preventing the anti-reverse guardrail from rotating clockwise. The anti-reverse guardrail moves to the right and downward under the drive of the misaligned sliding object, thus gradually reducing the distance between the anti-reverse guardrail and the fixed wheel at the lower right. The downward tension of the bridge cable on the anti-reverse guardrail can make... The misaligned sliding object presses against the skewed block via the inclined sliding surface, causing the extrusion round profile to be blocked by the Tesla stop mechanism. This prevents the risk of a temporary widening of the gap between the anti-reverse guardrail and the fixed wheel at the lower right. The reverse channel at the bottom of the Tesla stop mechanism greatly slows down the rightward movement speed of the extrusion round profile, causing the misaligned sliding object to move to the right first at the top of the skewed block. Before the anti-reverse guardrail locks the bridge cable, the skewed block cannot press against the misaligned sliding object, preventing the bridge cable from being unable to be effectively locked midway during its descent. Once the bridge cable is locked, its high gravity makes the elastic force of the powerful resetter negligible. This allows the anti-reverse guardrail to adaptively adjust the gap between the anti-reverse guardrail and the fixed wheel at the lower right according to the deformation of the bridge cable, thus maintaining the locking and anti-fall function of the bridge cable at all times and ensuring the safety of the bridge cable.

The winch 4 lifts the fixed frame 10 and the load-bearing rod 11 by winding the steel rope on the pulley block 9.

[0024] The stabilizing mechanism 102 includes a fixed frame 10. A load-bearing rod 11 and two rib sleeves 12 are welded to the top of the fixed frame 10. The fixed frame 10 is connected to the fine-tuning mechanism 101 via the load-bearing rod 11. The two rib sleeves 12 are integrally formed on both sides of the top of the fixed frame 10. A mounting assembly is connected to each rib sleeve 12. The mounting assembly includes a drive motor 13, a screw sleeve 14, and a clamping plate 15. The outer side of one end of the screw sleeve 14 is engaged with the inner wall of the rib sleeve 12. The drive motor 13 is mounted on the rib sleeve 12 by bolts. At one end of the prism sleeve 12, the clamping plate 15 is integrally formed on the other end of the threaded sleeve 14. The driving mechanism 13 pushes the threaded sleeve 14 to move in and out inside the prism sleeve 12 through the screw 38. The threaded sleeve 14 drives the clamping plate 15 to move the fixed frame 10. A power unit is connected to the fixed frame 10. The power unit includes a winding machine 16 and a flexible rope 17. The winding machine 16 drives the bridge cable to rise and fall through the flexible rope 17. A self-disengaging assembly is connected to the fixed frame 10. The self-disengaging assembly includes two motors 18, two screws 19, and two support sleeves 20. A vertical guide assembly is connected to the support sleeve 20. The vertical guide assembly includes a movable bracket 21, a fixed wheel 22, and a pressure sleeve 23. Two motors 18 drive screws 19 to move the movable bracket 21 and the pressure sleeve 23 in a defined direction within the support sleeve 20. The outer sides of one end of the movable bracket 21 and the pressure sleeve 23 are respectively engaged with the inner walls of the two support sleeves 20. The movable bracket 21 and the pressure sleeve 23 are respectively threaded onto the outer sides of the two screws 19. The fixed wheel 22 is mounted on the other end of the movable bracket 21 via a rotating shaft. The driving motor 13... The screw 38 is bolted to the outer side of one end of the prism sleeve 12. One end of the screw 38 is keyed to the output shaft of the drive machine 13. The screw sleeve 14 is threaded onto the outer side of the screw 38.

One end of the flexible rope 17 is connected to the inner side of the winding machine 16. The other end of the flexible rope 17 passes between the fixed wheel 22 and the anti-reverse guard 25 and extends to the bottom of the fixed frame 10.

[0025] Understandably, during operation, a ship is used to transport the tower crane base column 1, rotating control console 2, strong cross brace 3, fixed frame 10, and other structures to the installation platform where the cable-stayed bridge foundation is located. A ship-mounted hydrogeological survey winch is then used to place these structures one by one onto the platform, and the winch is used for raising and lowering to install and secure them. During operation, the rotating control console 2 rotates the strong cross brace 3 at the top of the tower crane base column 1. The trolley 8 moves the fixed frame 10 and load-bearing rod 11 via pulley block 9. The winch 4 raises and lowers the fixed frame 10 and load-bearing rod 11 via pulley block 9. Simultaneously, the power unit 6 pushes the counterweight 5 via the lead screw 7, which in turn moves the winch 4. This process avoids constantly ensuring the stability of the center of gravity and allows the fixed frame to be moved. 10 is hoisted to the bridge frame of the cable-stayed bridge where the cable-stayed structure needs to be installed. The position of the fixing frame 10 on the bridge frame is adjusted according to the installation position of the cable-stayed structure. Then, the drive motor 13 is turned on. The drive motor 13 drives the screw sleeve 14 to move inside the prism sleeve 12 through the screw 18. This causes the screw sleeve 14 to drive the clamping plate 15 to clamp and fix the fixing frame 10 on the bridge frame. At the same time, the clamping force of the clamping plate 15 and the pulling force of the pulley block 9 are used to fix the fixing frame 10. When lifting and lowering the fixing frame 10, the clamping plate 15, prism sleeve 12 and fixing frame 10 can be used to lift and move on the outside of the bridge frame. This can effectively prevent swaying due to slightly strong winds during the lifting operation of the cable-stayed bridge, thus ensuring the construction safety of the cable-stayed bridge installation operation.

The hydraulic oil in the liquid discharge tank 34 passes through the reverse channel 37 at the bottom of the Tesla baffle 36. The tilted block 32 is welded with an oil extrusion round profile 35. The oil extrusion round profile 35 inhibits the reset of the tilted block 32 on the inner side of the liquid discharge tank 34. The misaligned sliding object 31 is guided by the inclined sliding surface at the top of the tilted block 32. The falling bridge cable is locked by the anti-reverse guardrail 25. The inner side of the inner clamping structure 24 has an inner cavity and a sliding groove. The sliding groove is distributed at both ends of the inner cavity. One side of the misaligned sliding object 31 and the tilted block 32 is stuck on the inner wall of one side of the sliding groove. The other side of the misaligned sliding object 31 and the tilted block 32 is connected to the inner wall of the other side of the sliding groove through a powerful resetter 33. The two ends of the anti-reverse guardrail 25 are installed on the inner side of the misaligned sliding object 31 through a rotating shaft. The stopping recess 30 is formed around the anti-reverse guardrail 25. The bottom end of the vertical guide device 27 is welded to the top of the vertical pressure barrier 26. The top of the inner clamping structure 24 has a sliding opening. The vertical guide device 27 The top of the device passes through the sliding opening and extends to the outside of the inner mounting structure 24. The top of the vertical pressure barrier 26 is connected to the inner wall of the top of the inner cavity through the equal diameter screw feeder 28. The liquid slow discharge tank 34 is welded to the outer side of the inner mounting structure 24. The outer side of the Tesla baffle 36 is welded to the inner wall of the liquid slow discharge tank 34. The differential channel 37 is opened at the bottom of the Tesla baffle 36. The differential channel 37 is a Tesla valve. One end of the oil extrusion round profile 35 is integrally formed on the other side of the tilted block 32. The other end of the oil extrusion round profile 35 is clamped on the inner wall of the liquid slow discharge tank 34 through the sealing ring. The distance between the oil extrusion round profile 35 and the Tesla baffle 36 is equal to the width of the misaligned tilting object 31.

[0027] Understandably, after the fixed frame 10 is locked onto the cable tray, the bottom end of the flexible rope 17 is tied to the cable, and then the winding machine 16 winds up the flexible rope 17 to lift the cable upward. The movable support 21 and the inner clamping mechanism 24 limit the flexible rope 17 to prevent it from swaying. The flexible rope 17 moves the cable between the movable support 21 and the inner clamping mechanism 24, with one side of the cable pressed against the right side of the fixed wheel 22 and the other side pressed against the left side of the anti-reverse guardrail 25. The anti-reverse guardrail 25 pushes the misaligned sliding object 31, which pushes the tilted block 32 through the inclined sliding surface, causing both the misaligned sliding object 31 and the tilted block 32 to compress the powerful resetter 33 and move to the left until the fixed wheel 22 and the cable are aligned. The spacing of the anti-reverse guardrail 25 allows the bridge cable to pass through. The bottom of the vertical pressure barrier 26 is pressed against the top of the anti-reverse guardrail 25 by the elastic force of the equal-diameter screw feeder 28. This allows the anti-reverse guardrail 25 to rotate counterclockwise, enabling the through-and-reverse-stop protrusion 29 to be smoothly pushed open by the stop recess 30 and quickly locked into the inner side of the next stop recess 30. In the event of a bridge cable falling during installation, the through-and-reverse-stop protrusion 29 can effectively lock the stop recess 30. Simultaneously, the vertical guide device 27 keeps the vertical pressure barrier 26 from moving horizontally. This effectively uses the anti-reverse guardrail 25 and the fixed wheel 22 to lock the bridge cable, preventing it from falling and ensuring safe installation. This also addresses misaligned and tilted objects 31 and other issues. When the carrier block 32 moves to the left, it drives the extrusion round profile 35 to move towards the inside of the liquid-filling slow discharge tank 34. The extrusion round profile 35 smoothly squeezes the hydraulic oil on the right side of the liquid-filling slow discharge tank 34 through the reverse channel 37 at the bottom of the Tesla stop mechanism 36 to the left side of the liquid-filling slow discharge tank 34. When the bridge cable deforms under pressure due to its own material properties, the bridge cable pulls the anti-reverse guardrail 25 downward, causing the anti-reverse guardrail 25 to drive the misaligned tilting object 31 to slide to the right and downward on the top of the tilted carrier block 32 through the inclined sliding surface. The vertical pressure barrier 26 moves downward under the pressure of the equal diameter screw feeder 28 and inserts into the inside of the stop recess 30 through the anti-reverse convex protrusion 29 in real time, thereby preventing the anti-reverse guardrail 25 from rotating clockwise. The anti-reverse guardrail 25 is in the misaligned tilting Driven by object 31, it moves downwards and to the right, causing the distance between the anti-reverse guardrail 25 and the fixed wheel 22 at the lower right to gradually decrease. The downward tension of the bridge cable on the anti-reverse guardrail 25 allows the misaligned sliding object 31 to squeeze the skewed block 32 through the inclined sliding surface, thereby causing the extrusion round profile 35 to be blocked by the Tesla stop mechanism 36, preventing the risk of a temporary widening of the distance between the anti-reverse guardrail 25 and the fixed wheel 22 at the lower right. The reverse channel 37 at the bottom of the Tesla stop mechanism 36 can greatly slow down the rightward movement speed of the extrusion round profile 35, thus causing the misaligned sliding object 31 to move to the right first at the top of the skewed block 32. Before the anti-reverse guardrail 25 locks the bridge cable, the skewed block 32 cannot squeeze the misaligned sliding object 31.To prevent the bridge cable from failing to lock effectively midway during its descent, once locked, the cable's high gravity renders the spring force of the powerful resetter 33 negligible. This allows the anti-reverse guardrail 25 to adaptively adjust the distance between the anti-reverse guardrail 25 and the lower right fixed wheel 22 based on the cable's deformation, thus maintaining constant locking and anti-fall protection for the cable and ensuring its safety.
