The first support assembly 10 has a through first accommodating cavity, and the first support assembly 10 has an open state and a closed state. When in the open state, the first accommodating cavity is formed with an opening that enables the cable 1 to enter the first accommodating cavity.

The winding assembly 30 includes a rotating ring 31, a wire storage shaft 32, and a glue coating mechanism 33. The rotating ring 31 is arranged on the first supporting assembly 10 and is annular. The rotating ring 31 has a notch 311 that allows the inclined cable 1 to pass through. When the first supporting assembly 10 is in a closed state, the rotating ring 31 is arranged around the outer circumference of the inclined cable 1, the wire storage shaft 32 and the glue coating mechanism 33 are respectively arranged on the rotating ring 31, and a spiral wire 2 is wound on the wire storage shaft 32. The free end of the spiral wire 2 passes through the glue coating mechanism 33 and is wound around the outer wall of the inclined cable 1; the rotation drive assembly 40 is arranged on the first supporting assembly 10, and is used to drive the rotating ring 31 to rotate around the inclined cable 1.
[0025] Compared with the prior art, the bridge cable vibration suppression device provided in this embodiment has the following beneficial effects: The bridge cable vibration suppression device provided in this embodiment includes a first support assembly 10, a first travel assembly 20, a winding assembly 30 and a rotation drive assembly 40. The first support assembly 10 is sleeved on the outer periphery of the cable 1. The first travel assembly 20 includes a plurality of first travel wheels 21 arranged around the cable 1. The first travel wheels 21 have a built-in drive motor, so that the bridge cable vibration suppression device can travel along the length direction of the cable 1. During the travel process, the rotation drive assembly 40 can drive the rotating ring 31 of the winding assembly 30 to rotate around the cable 1, and the spiral wire 2 adhered with glue is spirally wound around the outer peripheral wall of the cable 1, so as to modify the aerodynamic shape of the cable 1 (for details, please refer to Figure 1 ). By changing the travel speed of the first travel wheel 21 and the rotation speed of the winding assembly 30, the pitch of the spiral wire 2 can be changed, thereby improving the wind-induced vibration resistance of the inclined cable 1 and achieving the effect of suppressing the vibration of the bridge inclined cable.
[0026] This embodiment can install the spiral wire 2 on the bridge cable, improve the wind-induced vibration resistance of the cable 1, and does not require personnel to work at high altitudes, which is safer and more efficient.
[0027] In this embodiment, the first support assembly 10 can be assembled from a plurality of frame members, and the plurality of frame members can be movably connected by connecting members such as bolts, latches, hinges, etc. The shape of the first support assembly 10 can be square, round, etc. Since the inclined cable 1 has been fixedly installed on the bridge, in order to enable the first support assembly 10 to be smoothly sleeved on the outer periphery of the inclined cable 1, the first support assembly 10 has an open state and a closed state. When in the open state, the first support assembly 10 has an opening that enables the inclined cable 1 to enter the first accommodating cavity. When in the closed state, the first support assembly 10 is coaxially sleeved on the outer periphery of the inclined cable 1, and the first walking wheel 21 abuts against the outer peripheral surface of the inclined cable 1.
[0028] The first running wheel 21 contacts the PE protective layer of the outer wall of the inclined cable 1. The first running wheel 21 can be provided with three, five, eight, etc. as required. The first running wheel 21 is driven to rotate by a built-in motor. The rotation axis of the first running wheel 21 is perpendicular to the long axis direction of the inclined cable 1. When rotating, it can drive the entire bridge inclined cable vibration suppression device to move along the long axis direction of the inclined cable 1.
[0029] The winding assembly 30 includes a rotating ring 31. When the rotating ring 31 is an integrated structure, the rotating ring 31 has the following features: Figure 5 The notch 311 is shown. The rotating ring 31 is rotatably connected to the first support assembly 10 and can rotate relative to the first support assembly 10. During the rotation of the rotating ring 31, the first traveling assembly 20 travels at a constant speed, so that the spiral wire 2 can be spirally wound around the outer periphery of the inclined cable 1, and the aerodynamic shape of the inclined cable 1 is modified to achieve the technical effect of suppressing wind-induced vibration.
[0030] The spiral wire 2 is coiled and arranged on the wire storage shaft 32. The free end of the spiral wire is adhered with glue by the glue coating mechanism 33 and then wound around the outer wall of the inclined cable 1. After the glue is cured, the spiral wire 2 and the inclined cable 1 are bonded as one.
[0031] The rotation drive assembly 40 is used to drive the rotating ring 31 to rotate at an appropriate speed. The rotation drive assembly 40 can be a power device such as a motor that can output rotational motion, and drives the rotating ring 31 to rotate through gear transmission, chain transmission, etc.
[0032] It should be noted that, since the inclined cable 1 is arranged at an angle, when installing the spiral wire 2, the bridge inclined cable vibration suppression device can be first moved to the top of the inclined cable 1, and then the bridge inclined cable vibration suppression device can be moved downward while installing the spiral wire 2. Of course, the bridge inclined cable vibration suppression device can also be moved upward while winding the spiral wire 2. The user can choose the above two operation methods according to the needs.
[0033] See also Figure 2 , Figure 3 and Figure 4 The first support assembly 10 includes two support frames 11, which are semi-circular. One end of the two support frames 11 is hinged, and the other end is detachably connected by fasteners. The two support frames 11 enclose a first accommodating cavity, and the first walking wheel 21 is arranged on the support frame 11.
[0034] In this embodiment, the support frame 11 is semi-circular, and the two support frames 11 can form a first annular accommodating chamber when they are matched. One end of the two support frames 11 is rotatably connected, and the other end is detachably connected by fasteners such as bolts. Each support frame 11 is provided with two or more first running wheels 21. When in the open state, the two support frames 11 are opened to each other, so that the first support assembly 10 can be coaxially sleeved on the outer periphery of the inclined cable 1. When the first support assembly 10 is installed in place, the two support frames 11 are closed, and the first running wheel 21 abuts against the outer wall of the inclined cable 1. The first running wheel 21 is driven to rotate by the built-in motor and can move up and down along the inclined cable 1.
[0035] See also Figure 2 and Figure 4 The support frame 11 is provided with an adjustment hole, which penetrates the wall thickness of the support frame 11. The first traveling assembly 20 further includes a support shaft 22, which is movably arranged in the adjustment hole. The first traveling wheel 21 is arranged at one end of the support shaft 22 extending into the first accommodation cavity. By changing the length of the support shaft 22 extending into the first accommodation cavity, it can adapt to the inclined cables 1 of different diameters. When the length of the support shaft 22 extending into the first telescopic cavity is determined, the support shaft 22 and the support frame 11 are locked and fixed as a whole by fasteners such as bolts.
[0036] See also Figure 5 and Figure 6 The glue coating mechanism 33 includes a plurality of glue boxes 331 and a plurality of extrusion units 332, and the extrusion units 332 are arranged one by one with the glue boxes 331. The plurality of glue boxes 331 are arranged at intervals on the rotating ring 31 along the circumferential direction, and the glue boxes 331 are provided with glue outlet holes 3311. The outer circumference of the glue boxes 331 is covered with absorbent cotton, and the absorbent cotton covers the glue outlet holes 3311. The absorbent cotton can absorb glue. The free ends of the spiral wire 2 are sequentially wound around the plurality of glue boxes 331 and then wound around the outer wall of the inclined cable 1; the plurality of extrusion units 332 are arranged one by one with the glue boxes 331, and the extrusion units 332 include a piston 3321 and a first push rod 3322. The piston 3321 is slidably arranged in the glue box 331, and the first push rod 3322 is arranged on the rotating ring 31, and is used to drive the piston 3321 to move in the glue box 331. The glue can be glass glue, quick-drying glue, etc.
[0037] In this embodiment, the glue coating mechanism 33 includes a plurality of glue boxes 331, each of which stores a certain amount of glue. The side wall of the glue box 331 is provided with a glue outlet hole 3311. When the spiral wire 2 passes through the glue box 331, glue can adhere to the surface, and then the spiral wire 2 is wound around the outer periphery of the inclined cable 1. After the glue is cured, it can be fixed on the inclined cable 1.
[0038] When applying glue, the first push rod 3322 pushes the piston 3321 to move into the glue box 331, and squeezes the glue out of the glue outlet hole 3311. By providing multiple glue boxes 331, it is ensured that a sufficient amount of glue can be adhered to the spiral wire 2. It should be noted that when the glue coating mechanism 33 is working, it can continuously discharge glue so that the spiral wire 2 is completely adhered to glue, or it can intermittently discharge glue, that is, the spiral wire 2 is intermittently coated with glue, so that the spiral wire 2 can be firmly fixed on the inclined cable 1.
[0039] See also Figure 2 , Figure 4 and Figure 5 The winding assembly 30 also includes a second push rod 34, which is disposed on the rotating ring 31. The free end of the spiral wire 2 is adsorbed on the second push rod 34 after passing through the glue coating mechanism 33. When the spiral wire 2 needs to be wound, the second push rod 34 is extended to make the free end of the spiral wire 2 abut against the outer wall of the inclined cable 1.
[0040] When the spiral wire 2 is first wound, the free end of the spiral wire 2 needs to be fixed to the inclined cable 1. If the spiral wire 2 is wound along the inclined cable 1 from bottom to top, the initial end of the spiral wire 2 can be fixed manually. If the spiral wire 2 is wound along the inclined cable 1 from top to bottom, the initial end of the spiral wire 2 needs to be automatically fixed to the inclined cable 1 by the mechanical structure of the device itself because it is at the top of the inclined cable 1.
[0041] In order to realize automatic fixation of the free end of the spiral wire 2, a second push rod 34 is further provided on the rotating ring 31 in the present embodiment. The second push rod 34 and the above-mentioned first push rod 3322 can both be electric push rods. The free end of the spiral wire 2 is temporarily fixed on the second push rod 34 by a detachable method such as magnetic attraction and gluing. When the spiral wire 2 needs to be wound, the second push rod 34 is extended so that the free end of the spiral wire 2 abuts against the outer peripheral wall of the inclined cable 1, and then the winding assembly 30 winds the spiral wire 2 on the inclined cable 1. After winding, the second push rod 34 can be retracted.
[0042] In the above-mentioned embodiment 1, the inclined cable 1 is fixed by gluing. The fixing speed of the glue is affected by factors such as the ambient temperature and air humidity. When the temperature is low, the glue solidifies slowly, and the spiral wire 2 may move or detach from the inclined cable 1 due to loose fixation. In order to shorten the curing time of the glue, on the basis of the above-mentioned embodiment 1, the embodiment 2 further includes a second support assembly 50, a second walking assembly 60 and a drying assembly 70. The second support assembly 50, the second walking assembly 60 and the drying assembly 70 work together to quickly dry the glue to solidify it, thereby improving the quality of the construction work.
[0043] See also Figure 7 , Figure 8 and Fig. 9 In the second embodiment, the bridge cable vibration suppression device further includes a second support assembly 50, a second travel assembly 60 and a drying assembly 70. The second support assembly 50 is connected to one end of the first support assembly 10 provided with a rotating ring 31, and the second support assembly 50 has a through second accommodating cavity, and the second support assembly 50 has an open state and a closed state. When in the open state, the second accommodating cavity is formed with an opening that allows the inclined cable 1 to enter the second accommodating cavity. When in the closed state, the second support assembly 50 is arranged around the outer circumference of the inclined cable 1; the second travel assembly 60 includes a plurality of second travel wheels 61, and the plurality of travel wheels are arranged in the second accommodating cavity at intervals along the circumferential direction, and the second travel wheels 61 are used to abut against the inclined cable 1; the drying assembly 70 is arranged on the second support assembly 50, and the drying assembly 70 is used to blow hot air into the second accommodating cavity. The drying assembly 70 can be specifically an electric hot air blower, and the hot air is used to quickly solidify the glue. One or more drying assemblies 70 can be provided as needed.
[0044] In this embodiment, the second support assembly 50 can adopt the same structure as the first support assembly 10, and the second travel assembly 60 can adopt the same structure as the first travel assembly 20. The second support assembly 50 is arranged behind the first support assembly 10 and is detachably connected to the first support assembly 10. The second support assembly 50 can be installed or removed according to weather conditions. For example, in sunny summer, the second support assembly 50, the second travel assembly 60 and the drying assembly 70 can be omitted. In weather with low temperature and high humidity, the second support assembly 50, the second travel assembly 60 and the drying assembly 70 can be installed to increase the curing speed of the glue and eliminate the adverse effects of weather factors.
[0045] Usually, the spiral wire 2 is wound from top to bottom, that is, the bridge cable vibration suppression device is first moved to the top of the cable 1, and then the bridge cable vibration suppression device is controlled to move from top to bottom along the cable 1, while the spiral wire 2 is wound on the surface of the cable 1. Since the second support assembly 50 and the second walking assembly 60 are arranged behind the first support assembly 10, if the second walking assembly 60 walks in a straight line along the length direction of the cable 1, the second walking wheel 61 will hit the spiral wire 2 that has just been wound, which may cause the spiral wire 2 to fall off.
[0046] To solve the above problems, see Figure 7 , Figure 8 and Fig. 9 The second walking assembly 60 also includes a plurality of adjustment shafts 62 respectively arranged on the first supporting assembly 10, the axial direction of the adjustment shaft 62 is parallel to the diameter direction of the inclined cable 1, and the second walking wheels 61 are respectively arranged at one end of the adjustment shaft 62 extending into the second accommodating cavity; the second walking assembly 60 also includes an adjustment mechanism 63, the adjustment mechanism 63 is arranged on the second supporting assembly 50 for driving the adjustment shaft 62 to rotate around its own axis, and the rotation drive assembly 40 can also drive the second supporting assembly 50 to rotate around the inclined cable 1.
[0047] In this embodiment, the rotary drive assembly 40 can also drive the rod second support assembly 50 to rotate around the inclined cable 1, so that the second walking wheel 61 can spirally walk along the winding direction of the spiral wire 2. The second walking wheel 61 can avoid the spiral wire 2 to prevent the spiral wire 2 from being hit and falling off.
[0048] like Figure 7 As shown, when the bridge cable vibration suppression device moves upward along the cable 1, the second running wheel 61 is consistent with the axial direction of the first running wheel 21, the second support assembly 50 does not rotate, and the second running wheel 61 and the first running wheel 21 rotate synchronously, driving the entire device to move upward along the cable 1. When the spiral wire 2 needs to be wound, the adjustment mechanism 63 drives the adjustment shaft 62 to rotate around its own axis by a certain angle, and the rotation drive assembly 40 drives the rotating ring 31 and the second support assembly 50 to rotate at the same time, and the second running wheel 61 moves spirally along the winding direction of the spiral wire 2, thereby avoiding the wound spiral wire 2.
[0049] See also Figure 7 , Figure 8 and Fig. 9 The rotating drive assembly 40 includes a plurality of driving wheels 41, which are arranged at intervals along the circumferential direction on the first support assembly 10, at least one driving wheel 41 is a driving wheel, and is driven to rotate by a motor; the outer circumferential surface of the rotating ring 31 abuts against the driving wheel 41, and the surface of the driving wheel 41 is coated with rubber material, which can increase friction and prevent slipping.
[0050] See also Figure 7 , Figure 8 and Fig. 9 The second support assembly 50 has a connecting ring 51, which is annular and coaxially arranged with the rotating ring 31. The inner ring of the connecting ring 51 abuts against the driving wheel 41. When the driving wheel 41 rotates, it can drive the connecting ring 51 and the rotating ring 31 to rotate at the same time. The connecting ring 51 can be formed by two detachably connected half rings.
[0051] When multiple spiral wires 2 need to be wound simultaneously, the winding assembly 30 includes multiple wire storage shafts 32 , which are arranged at intervals along the circumference of the rotating ring 31 , and each wire storage shaft 32 stores the spiral wire 2 .

The specific contents of each combination embodiment will not be repeated here. After this description, it can be considered that the specification of the present invention has recorded various combination embodiments and can support different combination embodiments.
