Description

Technical Field

[0001] This utility model relates to the field of overhead contact line busbar installation technology, and in particular to a rigid overhead contact line busbar adjustment device. Background Technology

[0002] Traditional rigid contact wire busbars are installed primarily by manually carrying them on their shoulders. First, the busbar is connected to a temporary positioning clamp. Then, during adjustment, the positioning clamp bolts are loosened, and the distance between the busbar connector and the suspension point is adjusted again using multiple people carrying it on their shoulders. After adjustment, the busbar positioning clamp bolts are tightened again to complete the busbar installation.

[0003] During the adjustment of the busbar, manual labor is required to adjust the distance between the connector position and the suspension point by carrying it on one's shoulders. Due to the weight of the busbar itself, this process is labor-intensive, complicated, and inefficient. It also requires repeated disassembly and reassembly of the busbar positioning clamps, making it impossible to install it correctly in one go. The adjustment is extensive and time-consuming.

[0004] Therefore, a rigid contact wire busbar adjustment device is needed to solve the above-mentioned technical problems. Utility Model Content

Horizontal adjustment knob, 6. Roller, 7. Busbar, 8. Vertical adjustment knob, 9. Anti-detachment pin, 10. Slider, 11. Hook, 12. Reinforcing plate. Detailed Implementation

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a rigid contact wire busbar adjustment device includes a suspension channel steel 1 and a transverse connecting frame 2. A hook 11 is installed on the transverse connecting frame 2. The cross-section of the suspension channel steel 1 is "U" shaped, and the hook 11 is hung on the suspension channel steel 1.

[0020] Both ends of the horizontal connecting frame 2 are fixedly connected to vertical plates 3, and an adjustment unit is installed at the bottom of each vertical plate 3. A busbar 7 is clamped between two adjustment units. In use, the busbar 7 is clamped and supported by multiple rigid contact network busbar adjustment devices of this utility model. At least one vertical plate 3 is equipped with an anti-detachment pin 9, which is located below the hook 11. After the hook 11 is hung on the suspension channel steel 1, the anti-detachment pin 9 is inserted into the bottom of the suspension channel steel 1 to prevent the horizontal connecting frame 2 from falling off. A reinforcing plate 12 is connected between two vertical plates 3 to ensure the overall structural strength. The reinforcing plate 12 is connected to the upper part of the vertical plate 3 to prevent obstruction of the insulator position. The horizontal connecting frame 2, vertical plates 3, and hook 11 are all made of aluminum alloy to reduce the overall weight.

[0021] The adjustment unit includes a horizontal adjustment component and a vertical adjustment component. The horizontal adjustment component includes a horizontal adjustment knob 5, a horizontal threaded rod, and rollers 6. The horizontal adjustment knob 5 and rollers 6 are respectively installed at both ends of the horizontal threaded rod, and rollers 6 are rotatably connected to the horizontal threaded rod. The horizontal threaded rod passes through the vertical plate 3. Slots are provided on both sides of the manifold 7, and two rollers 6 are respectively located in the slots on both sides of the manifold 7. The vertical adjustment component includes a vertical adjustment knob 8, a vertical threaded rod, an adjustment block 4, and a slider 10. The adjustment block 4 is fixed to the bottom of the vertical plate 3, and a vertical groove is provided inside the adjustment block 4. The slider 10 slides into the groove. The upper end of the vertical threaded rod passes through the interior of the adjustment block 4 and is rotatably connected to the bottom of the slider 10. The vertical threaded rod is threadedly connected to the adjustment block 4, and the vertical adjustment knob 8 is installed at the lower end of the vertical threaded rod. The horizontal threaded rod and the vertical threaded rod are perpendicular to each other, and the vertical threaded rod is parallel to the direction of the groove. The horizontal threaded rod passes through the interior of the slider 10 and is threadedly connected to the slider 10. The horizontal threaded rod, vertical threaded rod, horizontal adjustment knob 5, roller 6, and vertical adjustment knob 8 are all made of stainless steel, which improves the flexibility of rotation and durability.

[0022] Both the vertical plate 3 and the adjusting block 4 are provided with oblong holes, which are vertically oriented, through which the horizontal threaded rod passes. By rotating the vertical adjusting knob 8, the vertical threaded rod can be rotated, and under the action of the thread force, it moves itself, thereby moving the slider 10, which in turn moves the entire horizontal adjusting assembly up and down, thus adjusting the height position of the roller 6. The oblong hole design facilitates the vertical movement of the horizontal threaded rod.

[0023] Working Principle: After construction begins, the device is suspended from the suspension channel steel 1 via hook 11. After suspension, the anti-detachment pin 9 is opened to prevent the device from falling off during construction. After suspension, the space between the two vertical plates 3 and the horizontal connecting frame 2 is just enough to avoid the insulator and leave space for the busbar installation. Rotate the two horizontal adjustment knobs 5 to move the two rollers 6 outward. The operator places the upper edge of the busbar 7 on the rollers 6 using a ladder truck, rotates the horizontal adjustment knobs 5 to move the rollers 6 inward, and the rollers 6 engage with the slots on both sides of the busbar 7. The rollers 6 on both sides provide suspension support for the busbar, allowing the busbar 7 to slide smoothly on the rollers 6. The distance between the connector and the suspension point is adjusted by moving the busbar 7. Using the vertical adjustment knobs 8 on both sides of the bottom of the device, adjust the installation height of the busbar 7 to meet the design standard. Then, turn the horizontal adjustment knob 5 to tighten the roller 6 so that it abuts against the busbar 7, thus fixing the busbar and completing the installation and adjustment of the rigid contact network busbar.

[0024] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
