Description

Technical Field

[0001] The invention belongs to the technical field of cable strands of suspension bridges, in particular to a forming guide frame for zinc-aluminum-magnesium coated cable strands of suspension bridges. Background Art

[0002] A suspension bridge, also known as a suspension bridge, refers to a bridge that uses cables suspended from towers and anchored on both sides as the main load-bearing components of the superstructure. The cable geometry is determined by the force balance condition and is generally close to a parabola. Many hangers are hung from the cables to suspend the bridge deck. Stiffening beams are often set between the bridge deck and the hangers to form a combined system with the cables to reduce the deflection deformation caused by the load. In addition, the unit strand is a component of the cable in suspension bridges, self-anchored suspension bridges and other bridges and building structures. It is a load-bearing member of the cable in suspension bridges, self-anchored suspension bridges and other bridges and building structures. Among them, the steel wire bundle in the unit strand is composed of multiple steel wires twisted in the same direction spirally.

[0003] At present, the coating of steel wire for bridge cables is mainly galvanized. In recent years, some bridges have begun to use zinc-aluminum coated steel wire. Studies have shown that the corrosion resistance of zinc-aluminum coated steel wire is 2 to 4 times that of galvanized steel wire. With the latest technological development, zinc-aluminum-magnesium coated cable steel wire has begun to appear. Studies have shown that the corrosion resistance of zinc-aluminum-magnesium coated cable strands is more than 3 times that of zinc-aluminum coated cable strands. In order to greatly improve the service life and safety of cable bridges, it is necessary to use zinc-aluminum-magnesium coated steel wire in future bridge cables. However, whether it is zinc-aluminum coated steel wire or zinc-aluminum-magnesium coated steel wire, its friction coefficient is slightly lower than that of galvanized steel wire, which makes it difficult to pull the cable strand in the process of rolling the cable strand into a coil, and when the cable strand is rolled into a coil, the cable strand is unstable during molding, which is not conducive to construction, so that the cable strand is damaged. Summary of the invention

[0004] In view of this, the present invention provides a forming guide frame for zinc-aluminum-magnesium coated cables of a suspension bridge, which ensures stable cable forming, so as to meet industrial needs.

The cable strand conveying unit includes a conveying vehicle arranged on the guide rails, two lifting devices symmetrically arranged on the conveying vehicle, a rotating device arranged on the lifting devices, a cable strand guiding device arranged on the rotating device, and a control device. The rotating device includes a fixing plate arranged on the lifting device, a rotating shaft arranged on the fixing plate, a rotating plate arranged on the rotating shaft, and an angle sensor arranged at one end of the rotating shaft. The central axis of the rotating shaft is consistent with the extending direction of the guide rails.

The control device is connected to the angle sensor, the lifting device, and the driving unit. The lifting device is a screw jack, and the two longitudinal guiding devices are both clamped between the two transverse guiding devices. When the rotating plate rotates, the angle sensor transmits the rotation angle to the control device, and the control device can drive the lifting device or the driving unit to move, so that the cable strand is smoothly conveyed onto the winding wheel.

[0006] Further, each of the guide rails includes a guide rail main body arranged on the mounting platform, a sliding groove arranged on one side of the guide rail main body, and the outer contour of each guide rail is in a "C" shape.

[0007] Further, the conveying vehicle includes a vehicle body frame, a plurality of wheels arranged on the vehicle body frame, and two connecting pieces symmetrically arranged on both sides of the vehicle body frame.

[0008] Further, each of the wheels includes a wheel main body and an arc-shaped convex edge arranged on one side edge of the wheel main body.

[0009] Further, each of the longitudinal guiding devices includes a longitudinal mounting frame arranged on the vehicle body frame and a longitudinal roller arranged on the longitudinal mounting frame.

[0010] Furthermore, each of the transverse guiding devices includes two transverse mounting frames arranged on the vehicle body frame, and a transverse roller mounted on the transverse mounting frames, and the extension direction of the central axis of the gear lever is consistent with the extension direction of the transverse roller.

[0011] Furthermore, the active hinge assembly includes a driving sprocket bracket arranged on the mounting frame, a first mounting frame arranged on the driving sprocket bracket, a first connecting shaft arranged on the first mounting frame, and a driving sprocket arranged on the first connecting shaft.

[0013] Compared with the prior art, the forming guide frame of the zinc-aluminum-magnesium coated cable strand of the suspension bridge provided by the present invention drives the cable strand conveying unit to transfer the cable strand to the winding wheel through the driving unit. The driving unit drives the cable strand conveying unit to move back and forth along the guide rail. The cable strand conveying unit includes a conveying vehicle arranged on the guide rail, two lifting devices symmetrically arranged on the conveying vehicle, a rotating device arranged on the lifting device, a cable strand guiding device arranged on the rotating device, and a control device. The conveying vehicle is connected with the driving unit so that the driving unit drives the conveying vehicle to move back and forth along the guide rail. The lifting device is arranged on the conveying vehicle and drives the rotating device and the cable strand guiding device to be lifted and lowered, so that the cable strand on the cable strand guiding device rises, so as to ensure that the cable strand is always attached to the outer diameter of the winding wheel at a reasonable angle.

[0020] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0021] like Figures 1 to 5 As shown, it is a schematic diagram of the structure of the forming guide frame of the zinc-aluminum-magnesium-coated cable strand of the suspension bridge provided by the present invention. The forming guide frame of the zinc-aluminum-magnesium-coated cable strand of the suspension bridge comprises a mounting frame 1, two guide rails 10 symmetrically arranged on the mounting frame 1, a cable strand transmission unit 20 arranged on the guide rail 10 and used to transmit the cable strand 2 to the winding wheel 3, and a driving unit 30 arranged on the mounting frame 1. The forming guide frame of the zinc-aluminum-magnesium-coated cable strand of the suspension bridge also includes some other functional modules, such as assembly components, wires, etc., which should be well known to those skilled in the art and will not be described in detail one by one here.

[0022] The mounting platform 1 is used to mount the guide rail 10, the cable strand transmission unit 20, and the driving unit 30, so as to facilitate the transmission of the cable strand 2. The mounting platform 1 is a prior art and will not be described in detail herein.

[0023] Each of the guide rails 10 includes a guide rail main body 11 disposed on the mounting base 1 and a sliding groove 12 disposed on one side of the guide rail main body 11. The outer contour of each of the guide rails 10 is in a "C" shape. In addition, the sliding groove 12 cooperates with the strand conveying unit 20, and will be described in detail in combination with the strand conveying unit 20.

[0024] The strand conveying unit 20 includes a conveying vehicle 21 disposed on the guide rail 10, two lifting devices 22 symmetrically disposed on the conveying vehicle, a rotating device 23 disposed on the lifting device, a strand guiding device 24 disposed on the rotating device 23, and a control device 25.

[0025] The conveying vehicle 21 includes a vehicle body frame 211, a plurality of wheels 212 disposed on the vehicle body frame 211, and two connecting members 213 symmetrically disposed on both sides of the vehicle body frame 211. Each of the wheels 212 is received in the sliding groove 12 so that the strand conveying unit 20 slides stably along the guide rail 10.

[0026] Each of the wheels 212 includes a wheel main body 2121 and an arc-shaped convex edge 2122 disposed on one side edge of the wheel main body 2121. The arc-shaped convex edge 2122 abuts against one side of the guide rail 10 so that the position of the wheel 212 on the guide rail 10 is stable, thereby making the position of the strand conveying unit 20 on the guide rail 10 stable.

[0027] The connecting members 213 are respectively disposed on both side surfaces of the vehicle body frame 211 facing the driving unit 30, so as to facilitate the connection of the following active hinge assembly 31 and the following driven hinge assembly 32 to the strand conveying unit 20, thereby driving the strand conveying unit 20 to reciprocate along the guide rail 10, which will be described in combination with the driving unit 30.

[0028] The conveying vehicle 21 is disposed on the guide rail 10, and the conveying vehicle 21 slides along the guide rail 10, and the driving unit 30 is connected to the conveying vehicle 21 to reciprocate along the guide rail 10, which will be described in combination with the driving unit 30.

[0029] The lifting device 22, the rotating device 23, and the strand guide device 24 are sequentially arranged on the conveying vehicle 21, so that the rotating device 23 and the strand guide device 24 can be lifted and lowered, and the strand 2 on the strand guide device 24 is lifted, so that the strand 2 is always attached to the winding wheel 3 at a reasonable angle. As the strand 2 is gradually wound on the winding wheel 3, the outer diameter of the winding wheel 3 is gradually increased, so the lifting device 22 drives the strand guide device 24 and the strand 2 to lift, so that the strand 2 is stably wound on the winding wheel 3.

[0030] The rotating device 23 includes a fixed plate 231 disposed on the lifting device 22, a rotating shaft 232 disposed on the fixed plate 231, a rotating plate 233 disposed on the rotating shaft 232, and an angle sensor 234 disposed at one end of the rotating shaft 233. The rotating device 23 drives the cable strand guiding device 24 to rotate along the rotating shaft 232, so that the cable strand 2 disposed on the cable strand guiding device 24 and the winding wheel 3 are kept at a tangent angle of 10 to 20 degrees.

[0031] The fixed plate 231 is used to connect the lifting device 22, and the rotating shaft 232 connects the fixed plate 231 and the rotating plate 233 together. The central axis of the rotating shaft 232 is consistent with the extension direction of the guide rail 10. It can be imagined that the rotating plate 233 can rotate in the direction of the two guide rails 10, so that when the rotating plate 233 rotates around the rotating shaft 232, when the cable strand 2 is mounted on the cable strand guiding device 24, due to the traction force of the cable strand 2, the rotating plate 233 rotates to the side close to the winding wheel 3, so that the cable strand 2 is tilted and smoothly transmitted to the winding wheel 3.

[0032] The angle sensor 234, as the name implies, is used to detect an angle. When the angle sensor 234 rotates in one direction, the count increases, and when the rotation direction changes, the count decreases. The angle sensor is a prior art. In this embodiment, the angle sensor 234 is used to detect the angle between the rotating plate 233 and the horizontal plane, that is, the angle between the cable strand 2 and the horizontal plane.

[0033] The cable strand guiding device 24 includes two longitudinal guiding devices 241 disposed on the rotating plate, two transverse guiding devices 242 disposed on both sides of the longitudinal guiding device 241, and a stop rod 243 disposed on the longitudinal guiding device 241. The extension direction of the longitudinal guiding device 241 is perpendicular to the extension direction of the transverse guiding device 242. It can be imagined that the longitudinal guiding device 241 and the transverse guiding device 242 can guide the cable strand 2 to move from different directions, so that the cable strand 2 is stable during the movement. The two longitudinal guiding devices 241 are both sandwiched between the two transverse guiding devices 242, so that the longitudinal guiding device 241 and the transverse guiding device 242 are surrounded on the outside of the cable strand 2, so that the transmission of the cable strand 2 is stable. The cable strand guiding device 24 is used to guide the cable strand 2 to be transmitted to the winding wheel 3, prevent the cable strand 2 from twisting during the transmission process, and stably pull the cable strand 2 and wind it on the winding wheel 3.

[0034] Each of the longitudinal guide devices 241 includes a longitudinal mounting frame 2411 disposed on the vehicle body frame 211 and a longitudinal roller 2412 disposed on the longitudinal mounting frame 2411 .

[0035] Each of the transverse guiding devices 242 includes two transverse mounting frames 2421 disposed on the vehicle body frame 211 , and a transverse roller 2422 mounted on the transverse mounting frames 2421 .

[0036] The stop bar 243 is fixedly connected between the two longitudinal guide devices 241, and the extension direction of the central axis of the stop bar 243 is consistent with the extension direction of the transverse roller 2422. It can be imagined that the stop bar 243 is used to prevent the cable strand 2 from slipping out from between the two longitudinal rollers 2412. When the cable strand guiding device 24 transmits the cable strand 2, the cable strand 2 abuts against the transverse roller 2422, and the cable strand 2 passes between the two longitudinal rollers 2412, thereby smoothly guiding the transmission of the cable strand 2.

[0037] The control device 25 is connected to the angle sensor 234, the lifting device 22, and the driving unit 30. When the rotating plate 233 rotates, the angle sensor 234 transmits the rotation angle to the control device 25, and the control device 25 can drive the lifting device 22 or the driving unit 30 to move, so that the cable strand 2 is smoothly transferred to the winding wheel 3. The control device 25 is used to control the lifting and lowering of the lifting device 22 and the reciprocating movement of the driving unit 30. The control device 25 is an existing device. In this embodiment, the control device 25 not only controls the lifting device 22 and the switch of the driving unit 30, but also records the cumulative lifting height of the lifting device 22.

[0038] like Figure 6 The figure shows the structure of the active hinge assembly in the forming guide frame of the zinc-aluminum-magnesium coated cable strand of the suspension bridge. When the control device 25 controls the lifting and lowering of the lifting device 22, when the angle sensor 23 is between 10 degrees and 20 degrees, the lifting device 22 is stationary. When the angle sensor 23 is greater than 20 degrees, the lifting device 22 drives the rotating device 23 and the cable strand guide device 24 to rise until the angle sensor 23 is between 10 degrees and 20 degrees. In this embodiment, the lifting device 22 is a screw lift, which is driven by a servo motor so that the lifting device 22 is a screw lift with accurate and stable movement position.

[0039] When the lifting device 22 is stationary, the angle sensor 23 transmits the rotation angle to the control device 25, and the control device 25 calculates the circumference of the winding wheel 3, which is the distance that the driving unit 30 drives the conveying vehicle 21 to move, so that the driving unit 30 drives the conveying vehicle 21 to move along the guide rail 10.

[0040] When the lifting device 22 is at the initial position, the extension direction of the fixing plate 231 is tangent to the edge of the winding wheel 3. The control device 25 controls the sliding length of the cable strand conveying unit 20 along the guide rail 10 according to the formula A=2π(r+h+dtanθ), where r is the radius of the winding wheel 3, h is the cumulative rising height of the lifting device 22, d is the distance from the cable strand conveying unit 20 to the central axis of the winding wheel 3, and θ is the rotation angle detected by the angle sensor 23. The sliding length of the cable strand conveying unit 20 along the guide rail 10 calculated by this formula is the outer circumference after the cable strand 2 is wound around the outer diameter of the current winding wheel 3 for one more circle, so as to ensure the stability of the cable strand 2 wound on the winding wheel 3.

[0041] The driving unit 30 includes an active hinge assembly 31 disposed on the mounting platform 1 and at one end of the guide rail 10, and a driven hinge assembly 32 disposed on the mounting platform 1 and at the other end of the guide rail 10. The active hinge assembly 31 and the driven hinge assembly 32 are connected to both sides of the vehicle body frame 21 through a chain (not shown) to drive the cable strand transmission unit 20 to move along the guide rail 10.

[0042] The active hinge assembly 31 includes an active sprocket bracket 311 disposed on the mounting frame 1, a first mounting frame 312 disposed on the active sprocket bracket 311, a first connecting shaft 313 disposed on the first mounting frame 312, and an active sprocket 314 disposed on the first connecting shaft 313. One end of the first connecting shaft 312 is mounted on the first mounting frame 312, and the other end of the first connecting shaft 312 is connected to a motor (not shown), and the first connecting shaft 312 is driven to rotate by the motor.

[0043] The driven hinge assembly 32 includes a driven sprocket bracket 321 arranged on the mounting frame 1, two second mounting frames 322 arranged at intervals on the driven sprocket bracket 321, a second connecting shaft 323 arranged on the second mounting frames 322, and a driven sprocket 324 arranged on the second connecting shaft 323.

[0044] The chain (not shown) is mounted on the driven sprocket 324 and the driving sprocket 314, and both ends of the chain are respectively connected to the connecting member 213, so that the active hinge assembly 31 and the driven hinge assembly 32 can drive the cable strand transmission unit 20 to reciprocate along the guide rail 10.

[0045] Compared with the prior art, the forming guide frame of the zinc-aluminum-magnesium coated cable strand of the suspension bridge provided by the present invention drives the cable strand conveying unit 20 through the driving unit 30 to transfer the cable strand 2 to the winding wheel 3. The driving unit 30 drives the cable strand conveying unit 20 to move back and forth along the guide rail 10. The cable strand conveying unit 20 includes a conveying vehicle 21 arranged on the guide rail 10, two lifting devices 22 symmetrically arranged on the conveying vehicle, a rotating device 23 arranged on the lifting device, a cable strand guiding device 24 arranged on the rotating device 23, and a control device 25. The conveying vehicle 21 is connected to the driving unit 30 so that the driving unit 30 drives the conveying vehicle 21 to move back and forth along the guide rail 10. The lifting device 22 is arranged on the conveying vehicle 21, and drives the rotating device 23 and the cable strand guiding device 24 to be lifted and lowered, so that the cable strand 2 on the cable strand guiding device 24 rises, so as to ensure that the cable strand 2 is always attached to the outer diameter of the winding wheel 3 at a reasonable angle. The rotating device 23 drives the cable strand guiding device 24 to rotate, so that the cable strand 2 arranged on the cable strand guiding device 24 maintains a suitable tangent angle with the winding wheel 3, thereby ensuring that the cable strand 2 and the winding wheel 3 are stably wound. The cable strand guiding device 24 includes two longitudinal guiding devices 241 arranged on the rotating plate, two transverse guiding devices 242 respectively arranged on both sides of the longitudinal guiding device 241, and a stop rod 243 arranged on the longitudinal guiding device 241. The extension direction of the longitudinal guiding device 241 is perpendicular to the extension direction of the transverse guiding device 242. It can be imagined that the longitudinal guiding device 241 and the longitudinal guiding device 242 can guide the cable strand 2 to move from different directions, so that the cable strand 2 is stable during the movement. It can be seen from this that the forming guide frame of the zinc-aluminum-magnesium coated cable strand of the suspension bridge is easy to construct and operate, improves work efficiency, makes the cable strand transmission stable, and ensures the quality of the cable strand.
