Description

Technical Field

[0001] This utility model relates to the technical field of linear crossbeams, and in particular to a cement single-pole linear crossbeam. Background Technology

[0002] In power systems, the stable operation of transmission lines is crucial. To achieve this goal, various support equipment is required, among which crossbeams are an indispensable part. Traditional crossbeams are mostly made of metal materials such as angle iron. Although they have a certain strength and stability, they also have some shortcomings in long-term use.

[0003] For example, the existing technology authorization announcement number CN210888253U discloses a stable utility pole, including a pole body, a telescopic mechanism and an anti-collision mechanism. The telescopic mechanism is located on the upper outer surface of the pole body. The telescopic mechanism includes a crossbeam. An insulator is movably connected to the upper surface of the crossbeam. A first connecting rod is fixedly connected to the outer surfaces of both ends of the crossbeam. A guide rail is fixedly connected to the upper surface of the first connecting rod.

[0004] However, it was found during the use of this crossbeam that its installation method was relatively simple, which reduced its functionality, and the insulators had poor adjustment flexibility, which reduced the ease of use. Utility Model Content

The crossarm is mounted on the support device, which is used to fix the position of the crossarm. The positioning device is located on the outer wall of the crossarm and is used to fix the crossarm. The power line is supported by the upper part of the multiple sets of support seats. By rotating and adjusting the multiple sets of insulators, the insulators drive the multiple sets of studs to rotate, thereby moving the studs up or down through the internally threaded components. This improves the flexibility of insulator height adjustment and the convenience of power line support adjustment. By using the support device and positioning device to install and fix the crossarm in different ways, the convenience of installation and use of the crossarm in different environments is improved, reducing usage limitations.

[0007] Preferably, the support device includes a vertical rod, multiple sets of through holes, a first bolt, a connecting rod, a second bolt, and a third bolt.

The U-shaped component is fitted onto the outside of the utility pole, so that the support component is in close contact with the surface of the utility pole. Then, the two sets of first threaded sleeves are rotated, so that the two sets of first threaded sleeves engage with the thread to tighten the U-shaped component, thereby improving the convenience of installing the cross arm on the utility pole by cooperating with the U-shaped component and the support component.

[0009] Preferably, it also includes multiple sets of second threaded sleeves, which are respectively screwed onto the lower part of multiple sets of studs; after the multiple sets of insulators have been rotated and adjusted, by screwing the multiple sets of second threaded sleeves onto the lower part of multiple sets of studs and pressing the multiple sets of second threaded sleeves against the cross arm, the positioning convenience of the multiple sets of insulators is improved.

[0010] Preferably, it also includes multiple sets of V-shaped grooves, which are respectively arranged on the upper part of multiple support bases; by passing the power line through the inside of the V-shaped grooves, the limiting effect of the power line is improved, and the support stability of the power line is improved.
