Abstract
Description
Technical Field
[0001] This utility model relates to the field of installation support equipment, specifically a cable-stayed bridge tower cable guide installation and adjustment support. Background Technology
[0002] The existing cable guide positioning is carried out during the tower construction process. During construction, according to the requirements for the installation accuracy of the cable guide, it is necessary to use brackets to support and adjust the cable guide during installation. The existing brackets cannot quickly adjust the tilt angle and fixed position of the cable guide.
[0003] According to the patent document CN115613467B, a positioning and reinforcement device and construction method for cable-stayed bridge ducts are disclosed. The device includes several stiffening frames vertically fixed to the reinforcing steel bars of the bridge beam. These stiffening frames are evenly distributed along the extension direction of the cable duct. Each stiffening frame is equipped with a longitudinal positioning component for adjusting the longitudinal position of the cable duct, a transverse positioning component for adjusting the transverse position of the cable duct, and a clamping component for limiting the displacement of the cable duct. The longitudinal positioning component is connected to the cable duct to lift it. In use, the longitudinal position of the cable duct can be adjusted using a hand-operated hoist, and the transverse position can be adjusted by rotating the adjusting screw, making the position adjustment of the cable duct simpler and more convenient. However, while this solution facilitates position adjustment, it cannot simultaneously adjust the tilt angles at both ends, which is inconvenient in use. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an installation and adjustment bracket for the cable guide pipe of a cable-stayed bridge tower, thereby solving the problems mentioned in the background art. This utility model has a novel structure. In use, the threaded pipe rotates on the threaded column. When the threaded pipe rotates, the threaded column moves horizontally. The threaded column drives the support block and support rod to move inward and outward simultaneously. The inward and outward movement of the support rod changes the position of the guide pipe support point. The adjustment of the support point position simultaneously completes the adjustment of the guide pipe tilt angle.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable-stayed bridge tower duct installation and adjustment bracket, comprising a support base, a limiting plate movably mounted on the support base, support rods welded to the limiting plate, a horizontal plate welded between the support rods, a sliding groove on the horizontal plate, a slider movably mounted inside the sliding groove, a movable frame fixed on the slider, a displacement mechanism fixedly mounted on the movable frame, one end of the displacement mechanism fixed to the inner wall of the support rod, and reinforcing ribs welded between the movable frames.
[0006] Furthermore, the support base has a slot, and a support block is movably installed inside the slot, with one end of the support block welded to the support rod.
[0007] Furthermore, a threaded column is rotatably mounted on the support block, and a threaded tube is rotatably mounted between the threaded columns.
[0008] Furthermore, a fixing plate is welded to the side of the support base, and a fixing hole is opened on the fixing plate, and a bolt is movably installed inside the fixing hole.
[0009] Furthermore, a fixing groove is provided on the horizontal plate, a movable plate is movably installed inside the fixing groove, and a guide tube is movably installed between the movable plate and the movable frame.
[0010] Furthermore, a lifting mechanism is fixed to the bottom of the horizontal plate, and a movable column is installed on the lifting mechanism, with one end of the movable column fixed to the movable plate.
[0011] The beneficial effects of this utility model are:
[0012] 1. In use, the threaded pipe rotates on the threaded column, and the threaded column moves horizontally when the threaded pipe rotates. The threaded column drives the support block and the support rod to move inward and outward at the same time. The inward and outward movement of the support rod changes the position of the support point of the conduit. The adjustment of the support point position completes the adjustment of the tilt angle of the conduit.
[0013] 2. This is a cable-stayed bridge tower duct installation and adjustment bracket. The duct is installed between movable frames. The movable frames and movable plates cooperate to provide three-point support for the duct. The up and down movement of the movable plates allows for fine adjustment of the tilt angle of the duct support points. In addition, the movement of the movable frames allows for the limiting and fixing of ducts of different diameters. Attached Figure Description

Detailed Implementation
[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a cable-stayed bridge tower column cable guide installation and adjustment bracket, including a support base 1, a limiting plate 2 movably mounted on the support base 1, a support rod 3 welded to the limiting plate 2, a horizontal plate 9 welded between the support rods 3, a sliding groove 16 on the horizontal plate 9, a slider 17 movably mounted inside the sliding groove 16, a movable frame 10 fixed on the slider 17, a displacement mechanism 11 fixedly mounted on the movable frame 10, one end of the displacement mechanism 11 fixed to the inner wall of the support rod 3, reinforcing ribs 15 welded between the movable frames 10, a slot 4 on the support base 1, a support block 5 movably mounted inside the slot 4, one end of the support block 5 welded to the support rod 3, the displacement mechanism 11 and the lifting mechanism 14 are both linear reciprocating electric push rods, after the lifting mechanism 14 pushes the movable plate 13 to move between the movable frames 10, the movable plate 13 completes the support of the inner wall of the movable frame 10.
[0021] In this embodiment, a threaded column 6 is rotatably mounted on the support block 5, and a threaded tube 7 is rotatably mounted between the threaded columns 6. A fixing plate 8 is welded to the side of the support base 1, and a fixing hole is opened on the fixing plate 8. A bolt is movably installed inside the fixing hole. A fixing groove 12 is opened on the horizontal plate 9, and a movable plate 13 is movably installed inside the fixing groove 12. A guide tube 19 is movably installed between the movable plate 13 and the movable frame 10. A lifting mechanism 14 is fixed to the bottom of the horizontal plate 9, and a movable column 18 is mounted on the lifting mechanism 14. One end of the movable column 18 is fixed to the movable plate 13. The movable plate 13 pushes the guide tube 19 up and down under the push of the movable column 18 to adjust the tilt angle of the guide tube 19.
[0022] In use, the support base 1 is fixedly installed at the bridge pier via the fixing plate 8. After the support base 1 is fixed, the guide tube 19 is placed between the movable frames 10. After the guide tube 19 is placed, the displacement mechanism 11 is activated to push the movable frame 10 to move. The movable frame 10 moves inward and outward to adjust the width between them. The movement of the movable frame 10 completes the clamping and limiting of both sides of the guide tube 19. After the position of the movable frame 10 is adjusted, the tilt angle of the guide tube 19 is adjusted. After the guide tube 19 is installed on the horizontal plate 9, the front and rear heights of the horizontal plate 9 are staggered vertically. The guide tube 19 is installed on the horizontal plate 9 in its original tilted state. When... When adjusting the tilt angle, the threaded tube 7 is rotated, which drives the threaded column 6 to move. The movement of the threaded column 6 drives the support rod 3 to move through the support block 5. The support rod 3 moves inward or outward at the same time. When the support rod 3 moves, the horizontal plate 9 is also displaced. When the horizontal plate 9 moves, the support point position of the guide tube 19 changes. At the same time as the support point position changes, the tilt angle of the guide tube 19 is adjusted synchronously. While the horizontal plate 9 is adjusting the support, the lifting mechanism 14 is activated. The lifting mechanism 14 pushes the movable plate 13 up to complete the readjustment of the tilt angle of the guide tube 19, thereby completing the precise adjustment of the installation angle of the guide tube 19.
