Description

Technical Field

[0001] This utility model relates to the field of electrified railway construction technology, specifically a multi-directional rotating AF line suspension load-bearing column. Background Technology

[0002] AF line generally refers to the auxiliary conductors (such as protective conductors, positive feeders, return conductors, etc.) in electrified railways, excluding the catenary and contact conductors. These are collectively called auxiliary feeders (AF). The suspension posts are typically made of steel or concrete and are used to suspend the AF line above bridges, tunnels, or stations. Their main functions include supporting the conductor, fixing the AF line and maintaining its relative position to other parts of the contact network; providing electrical insulation (using insulators to achieve electrical isolation between the conductor and the post); ensuring mechanical stability; withstanding wind loads, ice loads, and conductor tension; and ensuring system safety.

[0003] During construction, the installation of the suspended column is affected by the direction of the AF line and changes in the installation position, thus affecting the vertical deviation of the suspended column. However, the existing technology lacks an adjustment mechanism, making it difficult to rotate the column in multiple directions, which makes it difficult to correct the verticality of the column and adjust the tension of the AF line. In order to solve the deficiency of the lack of a rotation adjustment mechanism in the existing technology, this application sets up components such as a first support box and a second support box, thereby driving the mounting plate and other components to rotate, thus achieving the effect of driving the suspended column body to rotate in multiple directions. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] This utility model discloses a multi-directional rotating AF line suspended load-bearing column, including a column body. A mounting plate is disposed above the column body. Two support plates are fixedly connected to the upper surface of the mounting plate. The two support plates are symmetrically installed. A first support box is rotatably connected between the two support plates. A second support box is rotatably connected to the upper surface of the first support box. A first worm gear and a first worm are rotatably connected inside the first support box. The first worm gear is fixedly connected to the two support plates and meshes with the first worm.

[0006] Furthermore, a fixing plate is fixedly connected to the top of the second support box, and a top frame is provided above the fixing plate.

[0007] Furthermore, a positioning plate is rotatably connected to both sides of the mounting plate, and each positioning plate has a positioning groove.

[0008] Furthermore, each of the positioning plates is fixedly connected to a support rod inside, and each support rod is rotatably connected to a drive bar at both ends.

[0009] Furthermore, two drive frames are slidably connected to the upper surface of the mounting plate, and the two drive frames are symmetrically installed.

[0010] Furthermore, a drive rod is provided above the mounting plate, and the outer surface of the drive rod is provided with bidirectional threads.

[0013] 1. This utility model, by setting up components such as a first support box and a second support box, and by setting up the mutual cooperation between the first support box and the second support box, enables the first support box and the second support box to drive the mounting plate and the hanging column body to rotate through the support plate, thereby achieving the effect of the utility model of driving the hanging column to rotate in multiple directions by setting up the first support box and the second support box.

[0014] 2. This utility model, by setting up components such as a positioning plate and a drive bar, and through the cooperation between the positioning plate and the drive bar, enables the drive bar to drive the positioning plate to rotate via the support rod, thereby making the positioning groove fit with the outer surface of the hanging column body, thus achieving the effect of auxiliary positioning and support of the hanging column by setting up the positioning plate and the drive bar.

A second worm gear 8 and a second worm 9 are rotatably connected inside the second support box 5. The second worm gear 8 and... The top of the first support box 4 is fixedly connected, and the second worm gear 8 and the second worm 9 mesh with each other. The outer surfaces of the relevant components described in this application are all galvanized for rust prevention. The bolts required for fixing need to be tightened symmetrically. The hanging column body 1 is fixed to the mounting plate 2 by fixing screws. A rotating wheel is fixedly installed at one end of the first worm 7 and the second worm 9. The second worm 9 drives the first support box 4 to rotate through the second worm gear 8, thereby driving the hanging column body 1 and other components to rotate horizontally. The first worm 7 drives the support plate 3 and other components to rotate through the first worm gear 6, thereby driving the tilt angle of the hanging column body 1, and thus driving the hanging column body 1 to rotate in multiple directions.

[0025] The top of the second support box 5 is fixedly connected to a fixing plate 10. A top frame 11 is set above the fixing plate 10. The top frame 11 is an embedded part. The top frame 11 is fixed to the inner top wall of the tunnel by chemical anchors. Two tracks are set on the lower surface of the top frame 11. The fixing plate 10 is fixed to the top frame 11 by bolts inside the tracks.

[0026] A positioning plate 12 is rotatably connected to both sides of the mounting plate 2. Each positioning plate 12 has a positioning groove 13. The positioning plates 12 are symmetrically installed. The positioning plates 12 position and provide auxiliary support for the installation of the hanging column body 1 through the positioning groove 13.

[0027] Each positioning plate 12 is fixedly connected to a support rod 14. Each support rod 14 is rotatably connected to a drive bar 15 at both ends. The drive bar 15 drives the positioning plate 12 to rotate through the support rod 14, thereby adjusting the position of the positioning plate 12 and supporting the positioning plate 12.

[0028] Two drive frames 16 are slidably connected to the upper surface of the mounting plate 2. The two drive frames 16 are symmetrically installed. Each drive frame 16 corresponds to two drive bars 15. Both ends of each drive frame 16 are rotatably connected to the other end of the corresponding drive bar 15.

[0030] Two limiting plates 18 are fixedly connected to the upper surface of the mounting plate 2. The two limiting plates 18 are symmetrically installed. The two limiting plates 18 are fixedly connected to the corresponding end of the drive rod 17. The limiting plates 18 support the drive rod 17. Each limiting plate 18 corresponds to one other limiting plate 18. The limiting plates 18 support the movement of the drive frame 16.

[0031] The implementation principle is as follows: the fixing plate 10 is fixed to the top frame 11 by screws, and the hanging column body 1 and the mounting plate 2 are fixed by screws. The drive rod 17 is rotated, which drives the drive frame 16 to slide. The drive frame 16 drives the positioning plate 12 to rotate through the drive bar 15 and the support rod 14, so that the positioning groove 13 is in contact with the outer surface of the hanging column body 1. The second worm 9 is rotated, which drives the second worm wheel 8 to rotate. The second worm wheel 8 drives the first support box 4 to rotate. The first support box 4 drives the support plate 3 and other components to rotate, thereby driving the hanging column body 1 to rotate horizontally. The first worm 7 is rotated, which drives the first worm wheel 6 to rotate. The first worm wheel 6 drives the support plate 3 and other components to rotate, thereby realizing the adjustment of the tilt angle of the hanging column body 1.
