Description

Technical Field

[0001] The invention relates to the technical field of cable installation, in particular to a multi-line bridge for rare earth aluminum alloy cables. Background Art

[0002] Rare earth aluminum alloy cable is based on high elongation aluminum alloy material, with specific rare earth trace elements added, such as a mixture of lanthanide elements, and is made through a special production process. The structure of this cable is similar to that of ordinary aluminum alloy cable, but its conductor part has better performance by adding rare earth elements and special treatment technology. Cable tray is mainly a component that must be used when laying cables. It mainly plays the role of fixing and supporting the cables, so that the laid cables can be laid in a specific space, making the laid cables more neat. Cable tray plays a big role in cable laying.

[0003] At present, when laying and installing cables on the bridge, workers first lay out the cables in the erected bridge, and then arrange the cables neatly. At this time, workers are required to arrange and fix multiple cables neatly one by one on the bridge. When wiring side by side, the cables have a certain hardness, which leads to high labor intensity for workers to lay the cables in parallel. Moreover, the bridges are hung on the top of the wall, which further increases the labor of laying the cables. When a single cable in the bridge is subsequently disassembled and replaced, workers are required to insert the newly laid cable into the disassembled gap, resulting in low laying efficiency.

The L-shaped rotating plate 24 on the sliding plate 25 is driven to move in the U-shaped groove 12 and the movable groove 13 by the sliding base 16, so that the L-shaped rotating plate 24 flips over, so that the wiring rack 20 connected to the support shaft 23 on the sliding plate 25 flips over in the bridge frame body 10.

[0041] See also Figure 1 , Figure 5 , Figure 6 , Figure 8 and Fig. 9A traction groove 18 penetrating the bridge body 10 is provided inside the sliding base 16, and a traction ring 19 is fixedly installed at the end of the T-shaped slider 26 away from the wiring rack 20 by bolts, and the traction ring 19 penetrates the traction groove 18 and extends to the outside of the bridge body 10. Workers pull the traction ring 19 from both sides of the bridge body 10 to make the wiring rack 20 move horizontally in the bridge body 10. When it moves to the U-shaped groove 12, the wiring rack 20 is flipped over, and the aluminum alloy cable is fixedly supported by the support block, and the aluminum alloy cable is guided and wired by the arc lead frame 30 for easy laying.

[0042] The top of the middle end of the wiring rack 20 is movably connected with a screw rod 21 through a bearing, and a rotating disk 27 that moves outside the wiring rack 20 is installed at the top of the screw rod 21. A lifting structure for adjusting the support frame 40 is provided on the top of the movable plate 22, and the lifting structure includes a triangular wedge block 28 for adjusting the support frame 40. The wiring rack 20 is fixed with a triangular wedge block 28 by bolts on the side close to the rotating disk 27, and the triangular wedge block 28 is movably abutted against the bottom of the support frame 40. The triangular wedge block 28 moves against the support frame 40, so that the arc lead frame 30 provided on the support frame 40 is pressed against the aluminum alloy cable. When the triangular connecting block is separated from the support frame 40, the telescopic spring 43 and the telescopic support rod 41 drive the arc lead frame 30 to reset, so as to prevent the arc lead frame 30 from being blocked during the subsequent flipping of the wiring rack 20.

[0043] See also Figure 4 , Figure 5 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 A telescopic spring 43 is fixedly installed on the top of the movable plate 22 by bolts, and the top of the telescopic spring 43 is fixedly installed on the bottom of the support frame 40 by bolts. The wiring frame 20 is provided with a plurality of limit grooves 44, and the telescopic spring 43 and the telescopic support rod 41 are both movable in the limit grooves 44. The height control of the arc lead frame 30 is achieved by the telescopic spring 43 and the telescopic support rod 41 in cooperation with the triangular connecting block.

[0044] The support frame 40 is provided with support holes 45 on both sides of the support groove 42, and an adjustment block 46 is slidably connected in the support groove 42. The arc lead frame 30 is fixedly mounted on the adjustment block 46 by bolts. The adjustment block 46 is provided with an adjustment hole 47 that matches the size of the support hole 45, and the support hole 45 and the adjustment hole 47 are connected through the support hole 45 and the adjustment hole 47. The position of the arc lead frame 30 can be conveniently adjusted through the support hole 45 and the adjustment hole 47 to complete the wiring guidance of the aluminum alloy cable at different positions.

[0045] See also Figure 6 , Figure 7 , Figure 8and Fig.11 The arc lead frame 30 is evenly provided with a plurality of limiting holes 31 on the side away from the wiring frame 20. A buffer spring 33 is fixedly installed at the bottom of the limiting hole 31 of the arc lead frame 30 by bolts. The buffer spring 33 is fixedly installed with a limiting frame 34 with a limiting roller 32 by bolts. The buffer spring 33 cooperates with the limiting roller 32 to fit and press the top of the aluminum alloy cable, so as to guide and arrange the aluminum alloy cable after laying out.

[0046] Positioning rods 29 are fixedly installed at both ends of the wiring rack 20 by bolts, and both ends of the movable plate 22 are movably inserted into the positioning rods 29. The arc-shaped support block 50 is provided with an arc-shaped groove 57 for limiting support of the aluminum alloy cable at the center of the side away from the connecting plate 56, and the arc-shaped groove 57 corresponds to the position of the support hole 45. The position of the arc-shaped lead frame 30 is adjusted through the support hole 45, so that the arc-shaped lead frame 30 and the arc-shaped groove 57 can guide the wiring and fix the aluminum alloy cable.

[0047] Working principle: The two ends of the bridge body 10 are supported and installed by the bridge hanger 11 and the supporting bracket 14. When laying out the wires, the position of the adjustment block 46 is adjusted through the support groove 42 on the support frame 40. After the position is adjusted appropriately, the support hole 45 on the support frame 40 and the adjustment hole 47 of the adjustment block 46 are used for limited support, so that the arc lead frame 30 on the support block fits the top of the aluminum alloy cable to be laid on the bridge body 10. The rotating disk 27 is operated to make the movable plate 22 on the screw rod 21 move horizontally in the positioning rod 29, so that the movable plate 22 moves toward one side of the triangular wedge block 28. The movable plate 22 moves At this time, the support frame 40 is synchronously driven to move by the telescopic support rod 41 and the limiting groove 44. At this time, the bottom of the support frame 40 moves against the triangular wedge block 28, and the distance between the support frame 40 and the wiring frame 20 is expanded, so that the limiting roller 32 on the arc lead frame 30 limits and presses the aluminum alloy cable. The operator pulls the traction ring 19 in the traction groove 18 from both sides of the bridge frame body 10, so that the arc lead frame 30 moves stably and horizontally on the top of the aluminum alloy cable. The arc lead frame 30 is used to lay the aluminum alloy cable in parallel to the bridge frame body 10 after the wire is released. The worker directly uses a disposable cable tie to pass through the installation hole 15 to bind the cable.

[0048] When it is necessary to dismantle and replace a single cable in the rear axle frame 10 after erection, the cable can be directly pulled out by cutting the tie. When erecting, the position of the arc lead frame 30 is adjusted by the support groove 42, the adjustment block 46, the support hole 45 and the adjustment hole 47 on the support frame 40, so that the arc lead frame 30 is located above the vacant position after the arc lead frame 30 is pulled out. Similarly, the limit roller 32 under the arc lead frame 30 is used to neatly lay and guide the new aluminum alloy cable, and accurately arrange it at the vacant position.

[0049] After the wiring is completed, the rotating disk 27 is operated to make the support frame 40 fall off from the triangular wedge block 28, and the support frame 40 is reset by the telescopic spring 43 and the telescopic support rod 41, and then the traction ring 19 is pulled to move the wiring frame 20 from the arc groove to the U-shaped groove 12. At this time, the sliding plate 25 provided on the sliding base 16 will drive the L-shaped rotating plate 24 to flip in the U-shaped groove 12. When the L-shaped rotating plate 24 rotates, it will synchronously drive the wiring frame 20 to flip through the support shaft 23, so that the arc lead frame 30 on the wiring frame 20 flips over. Turn to the top, with the support block under the connecting plate 56 facing downward, and further operate the rotating disk 27 to make the movable plate 22 move toward the side away from the triangular wedge block 28. When the movable plate 22 moves, the triangular moving plate 53 on the U-shaped base plate 52 is flipped through the connecting rod 51, so that the bottom of the triangular moving plate 53 pushes the moving rod 54 out through the hinge rod 55, and the moving rod 54 will drive the support block under the connecting plate 56 to limit the aluminum alloy cable after laying, so as to prevent the aluminum alloy cable from being affected and offset during daily use.
