Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and more specifically, to a crossarm of a power pole. Background Technology

[0002] As a key component in power equipment, the crossarm of a power pole bears the important task of supporting conductors, insulators and other accessories. The rationality and stability of its structural design are directly related to the overall safety and reliability of the power pole.

[0003] Existing technologies, such as the utility model of a crossarm and power pole, authorized by publication number CN221856389U, can achieve stable installation and reduce swaying and friction after installation, effectively extending the service life of the crossarm body and related components.

[0004] Currently, there is a lack of a crossarm for power poles that is easy to install on power poles and whose angle is adjustable for ease of use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a crossarm for power poles. By using clamps and threaded holes, the device can be easily installed on the power pole. The angle of the crossarm can be adjusted by using a moving component for easy use.

[0006] This utility model achieves its purpose through the following technical solution:

[0007] A crossarm for a power pole is characterized by comprising: a fixing component including clamps, which are mounted on the fixing component to ensure the stability of the entire structure. The clamps have suitable size and shape and are fixed to the power pole by fastening nuts and bolts to prevent loosening or displacement, providing a reliable guarantee for the normal use of the U-shaped crossarm. The clamps are fixedly connected to symmetrical mounting plates, which are respectively fixedly connected to large U-shafts and guide vertical rods; a crossarm assembly including symmetrical U-shaped crossarms made of high-strength materials, possessing sufficient load-bearing capacity to stably support the weight of power lines and related facilities, and having good corrosion resistance. The symmetrical U-shaped crossarms are respectively rotatably connected to the corresponding large U-shafts and are respectively fixedly connected to horizontal shafts; and a moving component including symmetrical sliders, which are respectively rotatably connected to power arms and respectively rotatably connected to the corresponding horizontal shafts. The symmetrical guide vertical rods pass through the corresponding sliders. The angle of the U-shaped crossarm is adjusted by moving the sliders along the guide vertical rods.

[0008] As a further limitation of this technical solution, the symmetrical sliders are respectively fixedly connected to fixing pins, and the symmetrical fixing pins are respectively fixedly connected to fixing half-rings, so that the sliders on both sides become a whole, and the U-shaped crossarms on both sides can be adjusted synchronously. The opening direction of the fixing half-rings is consistent with the opening direction of the clamp.

[0009] As a further limitation of this technical solution, the symmetrical sliders are respectively fixedly connected to threaded pins, the symmetrical threaded pins pass through the movable half-rings, and the symmetrical threaded pins are respectively threaded to lock nuts. By using movable half-rings, the stability of the connection between the sliders on both sides is enhanced.

[0010] As a further limitation of this technical solution, guide tubes are fixedly connected to the four corners of the symmetrical mounting plate. Reinforcing components are respectively installed within the four guide tubes on one side. Each reinforcing component includes a symmetrical H-bar. A set of positioning holes is provided on the lower crossbar of each of the symmetrical H-bars. Positioning pins are threaded to the lower two of the four guide tubes on one side, and these positioning pins are matched with the positioning holes. After the clamp is installed, the positioning pins are unscrewed from their end positioning holes, the H-bars are moved and inserted into the guide tubes on the other side, and the positioning pins are tightened into the appropriate positioning holes.

[0011] As a further limitation of this technical solution, the symmetrical guide vertical rods are each provided with a horizontal pin hole, and the symmetrical power arms are respectively threaded to a horizontal pin shaft, with the symmetrical horizontal pin shaft matching the symmetrical horizontal pin hole. The position of the horizontal pin hole is determined according to the required swing angle of the U-shaped crossarm. In use, the horizontal pin shaft is passed through and tightened into the horizontal pin hole to lock the position of the U-shaped crossarm.

[0012] As a further limitation of this technical solution, the symmetrical guide vertical rods are respectively fixedly connected to the limiting plates. The protective slider disengages from the guide vertical rods.

[0013] As a further limitation of this technical solution, the symmetrical mounting plates are each provided with threaded holes, and the symmetrical threaded holes penetrate the clamps. Corresponding mounting holes are pre-drilled on the power pole. After the clamps encircle the power pole, bolts are first used to connect the threaded holes and tighten them into the mounting holes.

[0014] As a further limitation of this technical solution, a set of fastening bolts are threaded through the open end of the clamp and connected to a fastening nut. This is used to install the clamp onto the power pole.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are:

[0016] (1) This utility model adopts an installation method that combines clamps and fastening bolts, and with the design of prefabricated installation holes and threaded holes, it not only simplifies the installation process, but also significantly enhances the fixing effect of the crossarm on the power pole, thereby comprehensively improving the overall performance and reliability of the crossarm of the power pole.

[0017] (2) By setting an adjustable U-shaped crossarm and a matching locking mechanism, this utility model can flexibly adjust the swing angle of the crossarm according to actual needs, and achieve precise positioning and firm locking through the cooperation of the cross pin shaft and the cross pin hole, effectively improving the flexibility and stability of the crossarm installation.
