Description

Technical Field

[0001] The utility model relates to the field of cable-stayed bridge cable conduit positioning devices, in particular to a cable-stayed bridge cable conduit positioning device. Background Art

[0002] With the continuous improvement of the level of social, economic and cultural development, people will pay more attention to the artistic modeling of bridge buildings and the landscape design of bridges. The aesthetic factors of bridge buildings will have an increasingly important impact on the construction of cable-stayed bridges. The continuous advancement of bridge construction technology has made it possible for people to meet the aesthetic functional requirements of architectural culture from a technical perspective. In recent years, many cable-stayed bridges with novel structures and beautiful shapes have emerged. The cable-stayed bridge is mainly composed of cable towers, cable stays and main beams. It is a high-order hyperstatic structure with complex forces, great mutual influence between components, and controllable internal forces and linearity. Regardless of whether the main beam is prestressed reinforced concrete or steel box beam, its huge weight is transmitted to the cable tower through the cable stays and their cable guides. Therefore, the stress and linear control of the cable stays are important contents of construction monitoring. The linearity of the cable stays is determined by the spatial position of the cable guide pipes on the tower and the beam. Therefore, the precise measurement and positioning of the spatial position of the cable guide pipes and their accuracy are important factors affecting the construction quality and line shape of the cable-stayed bridge.

[0003] The traditional cable-stayed bridge cable conduit positioning device uses multiple bolts to position and fix the conduit. Although this method is fixed, it is very likely to cause damage to the conduit, making the conduit unsightly. In addition, if the angle needs to be adjusted during the clamping and positioning process, the traditional method of turning multiple bolts is time-consuming and labor-intensive.

[0004] Therefore, we make improvements on this and propose a cable-stayed bridge cable conduit positioning device. Utility Model Content

The cross-shaped connecting column 6 moves outward, and the end of the long rod 4 away from the H-shaped connecting plate 3 pulls the cross-shaped connecting column 6 to move outward. The cross-shaped connecting column 6 slides on the U-shaped frame 1, and the cross-shaped connecting column 6 drives the arc clamping plate 7 to move outward. The front side of the H-shaped connecting plate 3 is provided with a control component, and the bottom of the U-shaped frame 1 is provided with a lifting component.

[0032] To facilitate adjustment, the control component includes a threaded rod 10 whose bearing is connected to the H-shaped connecting plate 3, and a threaded ring 9 is threadedly connected to the threaded rod 10. The bottom of the threaded ring 9 is fixedly connected to the mounting plate 2, and the end of the threaded rod 10 away from the H-shaped connecting plate 3 is fixedly connected to a handwheel 11. By turning the handwheel 11, the handwheel 11 drives the threaded rod 10 to rotate, and the threaded rod 10 rotates on the threaded ring 9, and the threaded rod 10 pushes the H-shaped connecting plate 3 to move forward.

[0033] In order to facilitate adjustment and fixation of the H-shaped connecting plate 3, a slide groove 12 is opened on the top of the mounting plate 2, and notches 19 are evenly opened in the slide groove 12. A slider 13 is slidably connected in the slide groove 12, and the top of the slider 13 is fixedly connected to the H-shaped connecting plate 3.
