Description

Technical Field

[0001] The invention relates to the technical field of lifting devices, in particular to a lifting device for installing cables of a cable-stayed bridge. Background Art

[0002] A cable-stayed bridge is a type of bridge that uses many cables to pull the main beam directly onto the bridge tower. It is a structural system that combines pressure-bearing towers, tension-bearing cables, and bending-bearing beams. It can be seen as a multi-span elastically supported continuous beam with cables replacing piers. It can reduce the bending moment in the beam body, lower the building height, reduce the structural weight, and save materials. A cable-stayed bridge is mainly composed of cable towers, main beams, and inclined cables. The inclined cables are the main load-bearing components that directly transfer the weight of the main beam and bridge deck of the cable-stayed bridge to the tower.

[0003] During the construction of cable-stayed bridges, tower cranes next to the tower columns are usually used to complete the installation of cable-stayed cables on the tower. However, as the span of the cable-stayed bridge increases, the tower column height increases, the cable stays longer and longer, and the weight of the cable stays heavier. After the tower crane has limited lifting capacity and changes in height, various unsafe conditions of the tower crane are increased. In addition, due to some restrictions on the shape of the tower column, some tower cranes are installed farther and farther away from the tower column, which further increases the safety risk of the tower crane. The larger the span of the cable-stayed bridge and the higher the tower column, the more cable stays there are and the longer the installation time. Especially in typhoon areas, the installation risk and construction cost of the cable stays are higher. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a cable-stayed bridge cable installation and lifting device to solve the problems raised in the above-mentioned background technology.

Electric push rods are fixed on both sides of the slide seat, and the extended ends of the electric push rods are fixedly connected to both sides of the connecting frame.

[0008] Furthermore, the driving assembly also includes a connecting block, a connecting block is fixed on the other side surface of the two groups of chains on the outside of the tower column, and connecting shafts are rotatably installed on the outside of the connecting block and the top of the connecting frame, and a push rod is installed between the two connecting shafts.

[0009] Furthermore, the guide and traction assembly also includes a guide frame, and the first inclined plate and the second inclined plate are both slidably sleeved with a guide frame at the intersection position, a rotating disk is rotatably installed on the inner side of the guide frame of the first inclined plate, and a plurality of pulleys are rotatably installed on the surface of the rotating disk and the connecting frame close to the tower column, and the pulleys slide along the surface of the tower column.

[0010] Furthermore, connecting rails are fixed to the outer sides of the guide frames of the first inclined plate and the second inclined plate, a connecting column is provided between the two connecting rails, and both ends of the connecting column are slidably inserted into the connecting rails.

The movable end of the lifting rope is fixedly connected to a clamping frame, and a bolt is threadedly inserted into the outer side of the clamping frame.

[0015] Beneficial effects of the present invention:

[0016] 1. The guide frame of the present invention is only slidably connected to the surfaces of the first inclined plate and the second inclined plate, and does not interfere with the movement of the transmission belt. Because the gears on the outer sides of the two sprockets at the top of the tower column are meshed and connected, when the driving motor drives the sprocket to rotate, the two gears are meshed so that the lifting devices of the sprockets and chains on both sides move synchronously, and the chains move in the opposite direction, so the rotating disk connected to the inner sides of the two chains can be subjected to two upward traction forces at the same time.

[0017] The second gear wheel is connected with the guide frame by the driving motor, and the second gear wheel is connected with the guide frame by the driving motor, and the driving motor drives the driving wheel of the driving belt to rotate, and the belt rotates and moves, driving the moving block and the clamping frame to move in the direction of the first inclined plate and the second inclined plate. In this process, because the lifting rope is connected with the clamping frame, the electric hoist can slide along the crossbeam synchronously, and in the process of sliding, the lifting rope is wound up by the electric hoist, and the oblique conveying of the transmission belt is cooperated with. The lifting rope lifts the steel cable, reduces the pressure of the transmission belt, and keeps the steel cable stably arranged and unfolded.

[0018] 3. The present invention cross-arranges the first inclined plate and the second inclined plate with the rotating disk as the center to avoid interference. At the same time, the two ends of the connecting column slide inside the connecting slide rail along the outer sides of the guide frames of the first inclined plate and the second inclined plate to keep the axes of the two guide frames on the same axis. When the first inclined plate and the second inclined plate rotate, the connecting column can slide along the connecting slide rail, thereby maintaining the coaxial rotation and lifting movement of the first inclined plate and the second inclined plate.

[0019] 4. In the present invention, the rotating disk slides along the tower column through the inner pulley, driving the guide frame to move upward. At the same time, the positions of the first inclined plate and the second inclined plate will also move upward, and the outer side of the chain will drive the connecting block to move downward. The slide seat is pushed to slide along the slide rail by the push rod. Since the bottom of the first inclined plate and the second inclined plate are connected to the slide seat, the horizontal direction of the bottom of the first inclined plate and the second inclined plate will change during this process, thereby satisfying the layout point of the replacement of the steel cable and adjusting the two layout and installation points at the same time. The electric push rods on both sides of the slide seat push the connecting frame to connect, so as to achieve error adjustment of the layout points at the bottom of the first inclined plate and the second inclined plate.

[0020] 5. Compared with the prior art, the present invention, through the cooperation of the driving assembly and the guide traction assembly, is guided by the first inclined plate and the second inclined plate at the two connection points of the steel cable at the tower column and the bridge deck, and the electric hoist cooperates with the movement of the traction steel cable to perform an oblique lifting movement from the fixed point of the bridge deck to the fixed point of the tower column, thereby improving the stability and safety of the steel cable during lifting and installation, and having guidance. Multiple groups of steel cables can be continuously installed through the inclined movement of the inclined plate, thereby improving the overall construction efficiency.

When the sprocket wheel (34) and the chain (35) are meshed and transmitted, the rotating disk (48) slides along the tower column (1) through the inner pulley (49), driving the guide frame (43) to move upward. At the same time, the positions of the first inclined plate (41) and the second inclined plate (42) will also move upward, and the outer side of the chain (35) will drive the connecting block (37) to move downward, and push the slide seat (51) to slide along the slide rail (5) through the push rod (33). Because the bottoms of the first inclined plate (41) and the second inclined plate (42) are connected to the slide seat (51), the first inclined plate (41) and the second inclined plate (42) are connected to the slide seat (51) during this process. 2) will change its bottom horizontal direction, thereby satisfying the arrangement point of the replacement steel cable, and adjusting the two arrangement and installation points at the same time. By pushing the connection frame (52) to connect through the electric push rods (53) on both sides of the slide seat (51), the error adjustment of the arrangement points at the bottom of the first inclined plate (41) and the second inclined plate (42) can be achieved. In actual operation, the anchor points on both sides of the tower column (1) are used as the first basic points, and then the anchor points of the bridge deck are adjusted, so that the lifting and deployment of the steel cables on both sides of the tower column (1) can be achieved at the same time. The deployment direction is the same as the original planned arrangement direction, and the arrangement points can be adjusted automatically by moving the first inclined plate (41) and the second inclined plate (42), so that the multiple steel cables on both sides of the cable-stayed bridge tower column (1) can be continuously arranged and lifted and installed.Improve the efficiency of construction.

[0033] In this embodiment, a connecting rail (410) is fixed to the outer side of the guide frame (43) of the first inclined plate (41) and the second inclined plate (42), a connecting column (411) is provided between the two connecting rails (410), and the two ends of the connecting column (411) are slidably inserted into the inside of the connecting rail (410), the first inclined plate (41) and the second inclined plate (42) are cross-arranged with the rotating disk (48) as the center to avoid interference, and at the same time, the two ends of the connecting column (411) slide along the inner side of the connecting rail (410) of the outer side of the guide frame (43) of the first inclined plate (41) and the second inclined plate (42), so as to keep the axis of the two guide frames (43) on the same axis. When the first inclined plate (41) and the second inclined plate (42) rotate, the connecting column (411) can slide along the connecting rail (410), thereby maintaining the coaxial rotation and lifting movement of the first inclined plate (41) and the second inclined plate (42).

[0034] In this embodiment, a transmission belt (44) is installed on the outer surface of the first inclined plate (41) and the second inclined plate (42), and two pulleys of the transmission belt (44) are respectively installed at the two ends of the first inclined plate (41) and the second inclined plate (42). A moving block (45) is fixed on one side of the belt of the transmission belt (44), and the moving block (45) slides along the surface of the first inclined plate (41) and the second inclined plate (42). The top of the moving block (45) is fixedly connected to the clamping frame (46). A driving motor (32) is fixedly installed on the back of the mounting plate (31) at the top of the tower column (1) and inside one end of the first inclined plate (41) and the second inclined plate (42). The driving motor (32) is fixedly connected to a sprocket wheel (34) on one side and a driving wheel of the transmission belt (44). The tower column (1) is fixedly connected, the two sprocket wheels (34) at the top of the tower column (1) are fixedly provided with gears (36) on the outside, the two gears (36) are meshingly connected, an electric hoist (22) is slidably sleeved on the surface of the cross beam (2), and a lifting rope (23) is passed through the bottom of the electric hoist (22), the movable end clamping frame (46) of the lifting rope (23) is fixedly connected, the outer side of the clamping frame (46) is threadedly plugged with bolts (47), the guide frame (43) is only slidably connected with the surface of the first inclined plate (41) and the second inclined plate (42), and does not interfere with the movement of the transmission belt (44), because the gears (36) on the outside of the two sprocket wheels (34) at the top of the tower column (1) are meshingly connected, and then when the driving motor (32) drives the sprocket wheel (34) to rotate, the two gears (36) ) are meshed so that the lifting devices of the sprockets (34) and chains (35) on both sides move synchronously, and the chains (35) move in the opposite direction, so the rotating disk (48) connected to the inner sides of the two chains (35) can be simultaneously subjected to two upward traction forces. After the first inclined plate (41) and the second inclined plate (42) on both sides of the tower column (1) rotate synchronously, the guide frame (43) is wrapped in a rotating manner and moves upward along with the chain (35). The slide seat (51) drives the first inclined plate (41) and the second inclined plate (42) to move outward along the slide rail (5). The first inclined plate (41) and the second inclined plate (42) pass through the guide frame (43), so that the positions of the first inclined plate (41) and the second inclined plate (42) adjacent to the tower column (1) and the bridge deck are two points where the steel cable needs to be anchored. At this time, the clamping frame (46) is moved to a position close to the bridge deck by the transmission belt (44). After one end of the steel cable is manually anchored to the installation position of the bridge deck, the other end is clamped and installed inside the clamping frame (46). The driving motor (32) drives the driving wheel of the transmission belt (44) to rotate, and the belt moves in a wheel rotation, driving the moving block (45) and the clamping frame (46) to move along the direction of the first inclined plate (41) and the second inclined plate (42). In this process, because of the connection between the lifting rope (23) and the clamping frame (46), the electric hoist (22) will slide synchronously along the crossbeam (2), and in the process of sliding, the lifting rope (23) is wound by the electric hoist (22), and the oblique conveying of the transmission belt (44) is coordinated. The lifting rope (23) lifts the steel cable to reduce the pressure of the transmission belt (44).The steel cable is kept stably arranged in an oblique direction and unfolded until the other end approaches the fixed position of the tower column (1). After the steel cable is fixed to the tower column (1), the clamping frame (46) is separated from the steel cable and returned to the original position. Since the height of the lowest point of the first inclined plate (41) and the second inclined plate (42) does not change, only the horizontal direction changes, each movement of the electric hoist (22) is synchronized with the clamping frame (46) to slide along the crossbeam (2).

[0035] When the device is used, the driving assembly (3) is installed on the outer surface of the tower column (1) through the mounting plate (31). After use, it can be disassembled. The first inclined plate (41) and the second inclined plate (42) are cross-arranged on the outer side of the tower column (1) and are fixedly connected to the inner side of the chain (35) through the rotating disk (48). When the sprocket wheel (34) and the chain (35) are meshed and transmitted, the rotating disk (48) slides along the tower column (1) through the inner pulley (49), driving the guide frame (43) to move upward. At the same time, the positions of the first inclined plate (41) and the second inclined plate (42) will also move upward, and the outer side of the chain (35) will drive the connecting block (37) to move downward, and the push rod (33) will push the connecting block (37) to move downward. The slide seat (51) slides along the slide rail (5). Since the bottom of the first inclined plate (41) and the second inclined plate (42) are connected to the slide seat (51), the horizontal direction of the bottom of the first inclined plate (41) and the second inclined plate (42) will change during this process, thereby satisfying the arrangement point of the replacement steel cable. At the same time, the two arrangement and installation points are adjusted. The electric push rods (53) on both sides of the slide seat (51) push the connection frame (52) to connect, so as to achieve the error adjustment of the arrangement point of the bottom of the first inclined plate (41) and the second inclined plate (42). After one end of the steel cable is artificially anchored to the bridge deck installation position, the other end is clamped and installed inside the clamping frame (46). The driving motor (32) drives the driving wheel of the transmission belt (44) to rotate. The belt rotates and moves, driving the moving block (45) and the clamping frame (46) to move in the direction of the first inclined plate (41) and the second inclined plate (42). During this process, because the lifting rope (23) is connected to the clamping frame (46), the electric hoist (22) will slide synchronously along the crossbeam (2), and in the process of sliding, the lifting rope (23) is wound by the electric hoist (22), and the oblique conveying of the transmission belt (44) is coordinated. The lifting rope (23) lifts the steel cable, reduces the pressure of the transmission belt (44), and keeps the steel cable stably arranged and unfolded in an oblique direction until the other end is close to the tower column (1) and fixed. After the steel cable is fixed on the tower column (1), the clamping frame (46) is separated from the steel cable and returns to its original position. Since the height of the lowest point of the first inclined plate (41) and the second inclined plate (42) does not change, only the horizontal direction changes, each movement of the electric hoist (22) is synchronized with the clamping frame (46) to slide along the cross beam (2). In actual operation, the anchor points on both sides of the tower column (1) are used as the first basic points, and then the anchor points of the bridge deck are adjusted, so that the lifting and deployment of the steel cables on both sides of the tower column (1) can be achieved at the same time. The deployment direction is the same as the direction of the original planned layout, and the layout point can be adjusted by the movement of the first inclined plate (41) and the second inclined plate (42), so that the multiple steel cables on both sides of the cable-stayed bridge tower column (1) can be continuously arranged and lifted and installed, thereby improving the construction efficiency.
