Description

Technical Field

[0001] This utility model relates to the field of composite crossarm technology, and in particular to a rotatable and adjustable composite crossarm. Background Technology

[0002] Composite insulated crossarms generally consist of an insulating core, an outer jacket, and end fittings fixed to the insulating core. Composite insulated crossarms can effectively improve the lightning protection performance of 10kV distribution lines and reduce the line tripping rate due to lightning strikes. Therefore, composite insulated crossarms are widely used on transmission lines.

[0003] Traditional composite crossarms have some drawbacks. Currently, composite insulated crossarms are mostly used on straight poles, mainly bearing vertical loads. However, during installation, although workers need to adjust the angle according to the site conditions, the installation method itself does not fully consider the influence of the installation angle, resulting in composite insulated crossarms not being able to adapt well to straight poles under different site conditions. Utility Model Content

[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] like Figure 1-4 As shown, a rotatable and adjustable composite crossarm includes a support base 1 and an insulator 2. One end of the support base 1 is provided with an adjustment auxiliary mechanism 6. The adjustment auxiliary mechanism 6 includes a fixed base 61 fixedly connected to one end of the support base 1. One end of the fixed base 61 is fixedly connected to a guide plate 62. A limiting groove 63 is opened on the inner wall of the guide plate 62. A turntable 64 is movably connected to the inner side of the guide plate 62. One end of the turntable 64 is provided with a positioning hole 65. A threaded rod 66 is movably connected to the inner side of the positioning hole 65. An internal threaded ring 67 is threadedly connected to the outer side of the threaded rod 66 near the positioning hole 65. A limit block 68 is movably connected inside the turntable 64. A scale 69 is fixedly connected to the outer side of the guide plate 62. An indicator frame 610 is slidably connected to the outer side of the scale 69. A connector 611 is fixedly connected to the upper end of the indicator frame 610. A support rod 612 is fixedly connected to the front side of one end of the turntable 64 near the positioning hole 65.

[0021] In this embodiment, the upper end of the support rod 612 is fixedly connected to the mounting rod 613, and the outer side of the mounting rod 613 is fixedly connected to the connecting ring 614. The shape of the limiting groove 63 is arc-shaped, and the positioning hole 65 corresponds to the limiting groove 63. The outer side of the threaded rod 66 near the positioning hole 65 is slidably connected to the inner side of the limiting groove 63. There are two sets of internal threaded rings 67. The other set of internal threaded rings 67 is installed on the outer side of the threaded rod 66 near the limiting groove 63. The two sets of internal threaded rings 67 respectively contact the turntable 64 and the guide plate 62. One end of the limiting block 68 is fixedly connected to the inner wall of the guide plate 62 near the front side of the limiting groove 63. One end of the connector 611 is fixedly connected to one end of the connecting ring 614.

[0022] Specifically, by loosening the two sets of internal threaded rings 67 and then pulling the insulator 2, the insulator 2 is brought to the turntable 64 via the mounting rod 613 and support rod 612 and rotated inside the guide plate 62, thus adjusting the installation angle of the insulator 2. The mounting rod 613 is also brought to the connecting ring 614 for synchronous rotation, and the connecting ring 614 is brought to the indicator frame 610 via the connector 611 and slid along the outer side of the scale 69, causing the indicator frame 610 to point to the new position on the scale 69. This allows the worker to clearly observe the adjusted angle of the insulator 2, facilitating accurate and effective angle adjustment. By rotating the insulator 2, the turntable 64 rotates synchronously with the insulator 2, and the connector 611 is brought to the indicator frame 610 and slid along the scale 69, causing the indicator frame 610 to point to the new position on the scale 69. This achieves the purpose of allowing the worker to clearly observe the adjusted angle of the insulator 2, adjust the installation angle of the insulator 2, and accurately and effectively specify the angle of the insulator 2.

[0023] In this embodiment, the insulator 2 is installed at the upper end of the mounting rod 613, and the lower end of the support 1 is fixedly connected to the mounting base 3. One end of the mounting base 3 is provided with a mounting groove 4, and a bolt 5 is installed on the inner side of the mounting groove 4. The mounting base 3 is U-shaped.

[0024] Specifically, first, the mounting base 3 is clipped onto the outside of the straight rod, then the bolt 5 is inserted into the inside of the mounting groove 4, and the bolt 5 is passed through the straight rod and tightened, thereby fixing the mounting base 3 on the straight rod and installing the insulator 2 on the straight rod.

[0025] Working principle:

[0026] During installation, first, the mounting base 3 is secured to the outside of the straight rod. Then, the bolt 5 is inserted into the inside of the mounting groove 4, passed through the straight rod, and tightened. This secures the mounting base 3 to the straight rod, and the insulator 2 is then installed on the straight rod. Next, the two sets of internal threaded rings 67 are loosened, and the insulator 2 is pulled. This causes the insulator 2 to rotate within the guide plate 62 via the mounting rod 613 and support rod 612, adjusting the installation angle of the insulator 2. The mounting rod 613 then rotates synchronously with the connecting ring 614, which in turn rotates along the outside of the scale 69 via the connecting piece 611. This causes the indicator 610 to point to the new position on the scale 69. This allows workers to clearly observe the adjustment angle of insulator 2, facilitating accurate and effective angle adjustment. Then, the two sets of internal threaded rings 67 are tightened, causing them to contact the turntable 64 and guide plate 62 respectively. This confines the turntable 64 within the guide plate 62 and limits the adjustment angle of insulator 2. By rotating insulator 2, the turntable 64 rotates synchronously with insulator 2, and the connector 611 slides along the scale 69 onto the indicator frame 610, causing the indicator frame 610 to point to a new position on the scale 69. This achieves the goal of allowing workers to clearly observe the adjustment angle of insulator 2, adjust the installation angle of insulator 2, and accurately and effectively specify the angle of insulator 2.
