It is a structural system composed of pressure-bearing towers, tensioned cables, and bending 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, lower the building height, reduce the structural weight, and save materials. A cable-stayed bridge is mainly composed of a cable tower, a main beam, and a cable. The cable is the link between the cable tower and the main beam of a cable-stayed bridge.

[0052] like Figure 1 As shown, the utility model provides a cable-stayed bridge cableway pipe positioning device, comprising:

[0053] Base 1; Base 1 is installed on the bridge deck;

[0065] The present application provides a cable-stayed bridge cableway tube positioning device, which adopts an electric turntable 2 and a hydraulic cylinder 4 as driving components, and respectively adjusts the deflection angle of the positioning shell 5 in the horizontal plane and the deflection angle in the vertical plane, thereby realizing multi-angle adjustment of the cableway tube, reducing the difficulty of cableway tube positioning, improving positioning accuracy, and breaking through the limitation that the existing positioning device can only be adjusted in a single direction.

[0066] In one embodiment, Figure 2 As shown, two cableway tube clamps 7 are symmetrically arranged in the positioning housing 5;

[0067] Each cableway tube clamp plate 7 is configured as an arc-shaped plate;

[0068] The cableway pipe is clamped between two cableway pipe clamping plates 7 .

[0069] The inner side of each cableway tube clamping plate 7 is connected with a rubber pad.

[0070] The working principle and beneficial effects of the above technical solution are:

[0071] The cableway pipe is clamped by the cableway pipe clamping plate 7 in the positioning shell 5, and the arc-shaped plate can better fit the surface of the cableway pipe; a rubber pad is arranged on the cableway pipe clamping plate 7 to reduce the clamping damage to the cableway pipe and narrow the clamping gap.

[0072] In one embodiment, Figure 3 , 4 As shown, an adjustment slot 8 is provided at the bottom of the positioning housing 5;

[0083] The first adjustment component 9 is arranged in the positioning housing 5. When the first adjustment component 9 is used, the first driving member 14 drives the first threaded rod 11 to rotate, and the first threaded section on the first threaded rod 11 is threadedly transmitted with the adjustment block 12, driving the adjustment block 12 to slide in the adjustment groove 8; the two first threaded sections rotate in opposite directions, so that the two adjustment blocks 12 move synchronously toward the center or toward the sides; when the two adjustment blocks 12 move synchronously toward the center, the two cableway tube clamps 7 are driven to approach each other to stably clamp the cableway tube; when the two adjustment blocks 12 move synchronously toward the sides, the two cableway tube clamps 7 are driven to move away from each other to loosen the cableway tube, making it easier to remove the cableway tube.

[0085] In one embodiment, Figure 3 , 4 As shown, a second adjustment component 10 is disposed in the adjustment slot 8;

[0086] The second adjustment assembly 10 comprises:

[0087] A second threaded rod 15;

[0088] The second threaded rod 15 is rotatably connected to the inner wall of the adjustment groove 8, and one end thereof penetrates the positioning housing 5; the second threaded rod 15 passes through the through hole 19 on the upper portion of the adjustment block 12; two second threaded sections are symmetrically arranged on the second threaded rod 15; the threaded directions of the two second threaded sections are opposite;

[0089] Adjustment plate 16;

[0090] The threaded hole at the center of the adjustment plate 16 is connected to the second threaded section; a groove 17 for accommodating the adjustment plate 16 is provided at the top of the adjustment block 12; the adjustment plate 16 slides relative to the bottom of the groove 17;

[0091] Turn plate 18;

[0092] The two ends of the rotating plate 18 are respectively hinged to the adjusting plate 16 and the outer side surface of the cableway tube clamping plate 7.

[0094] The working principle and beneficial effects of the above technical solution are:

[0095] A second adjustment assembly 10 is arranged in the adjustment groove 8. When the second adjustment assembly 10 is used, the second threaded rod 15 is driven to rotate by the second driving member 20. The second threaded rod 15 is screwed with the adjustment plate 16, driving the adjustment plate 16 to slide in the groove 17. The adjustment plate 16 drives the upper part of the cableway tube clamp 7 to rotate through the rotating plate 18 to adjust the angle of the cableway tube clamp 7. The arrangement of the two second threaded sections enables the two cableway tube clamps 7 to be adjusted synchronously. Through the above adjustment method, when the cableway tube deviates toward the bottom end of the cableway tube clamp 7 under the action of gravity, the angle of the cableway tube clamp 7 can be adjusted so that the upper part of the cableway tube clamp 7 can also be kept close to the surface of the cableway tube, thereby reducing the gap and shaking and improving the installation stability of the cableway tube.
