Description

Technical Field

[0001] This invention relates to the field of technology, specifically to a crossarm assembly for power construction. Background Technology

[0002] A power crossarm is an angle iron fixed horizontally at the top of a power pole, usually equipped with porcelain insulators (insulators) for installing insulators and fittings to support conductors, lightning protection wires, etc. The power crossarm is an important component of the pole and plays a key role in ensuring the safe and stable operation of the power system. The crossarm is generally installed at a certain distance from the top of the pole, and the specific location needs to be determined based on factors such as conductor type, voltage level, and pole structure.

[0003] In the prior art, Chinese patent publication number "CN214255641U" discloses a crossarm structure in which one end of a connecting rod is rotatably connected to the second bolt assembly of the lower fixing mechanism, and the other end of the connecting rod is detachably installed on a horizontal crossbar. During installation, the height difference between the lower and upper fixing mechanisms can be adjusted according to the actual installation environment to meet different installation requirements. The connecting rod is rotatably connected to the second bolt assembly, and when the first and second fixing plates are locked, the linkage locking of the connecting rod can be ensured, which improves the fixing quality of the connecting rod. The locking of the connecting rod can be achieved without additional auxiliary locking structures, and the locking effect is good, which improves the fixing quality of the crossarm structure. Moreover, the overall installation and disassembly are convenient. It solves the problem that existing lead wires are spliced ​​from the middle, and because the splicing from the middle cannot be completed when energized, the lead wires are prone to shaking, which cannot guarantee the safety of operators and equipment.

[0004] In the scheme described above, the height of the insulator on the crossarm can be adjusted by the cooperation of the connecting rod and the second threaded assembly. However, in this scheme, the distance between the insulators cannot be adjusted. Since different installation environments and power system requirements may have different insulator position requirements, if the position cannot be adjusted, it may lead to the inability to adapt to different working environments and conditions, reducing the versatility and adaptability of the equipment.

[0018] This invention provides a crossarm assembly for power construction. Compared with the prior art, it has the following advantages:

[0019] 1. In this invention, when it is necessary to adjust the position of the insulator on the insulating crossarm, the adjusting screw is rotated by adjusting the wrench. The adjusting plate on the adjusting screw will be limited by the translation groove, thereby adjusting the insulating crossarm on the adjusting plate. The insulator on the insulating crossarm will move synchronously with the insulating crossarm in the left and right directions. At the same time, the worm gear is driven to rotate by the drive wrench. The worm gear and worm wheel cooperate to drive the drive rod on the T-shaped shaft. The drive rod and the connecting frame cooperate, the connecting frame and the sliding block cooperate, and the sliding block and the sliding groove limit the sliding, thereby completing the movement of the insulator in the front and back directions. The adjustable insulator can adapt to different installation conditions or working conditions, improving the versatility of the crossarm assembly.

[0020] 2. In this invention, when the adjusting screw rotates, it drives the upper gear to rotate synchronously. When the upper gear rotates, it drives the lower gear to rotate synchronously via the chain. When the lower gear rotates, it drives the positioning screw to rotate. The positioning plate on the positioning screw slides through the limiting sliding between the positioning slider and the positioning groove, thereby sliding in the movable groove. The movement of the positioning plate drives the stabilizing frame rod on the positioning slider to move synchronously. By using the stabilizing frame rod that can be adjusted synchronously with the insulating crossarm, the stability of the insulating crossarm on the pole is effectively improved.

[0021] 3. In this invention, when the stabilizing pole moves synchronously with the U-shaped frame plate on the insulating crossarm, the linkage rod on the stabilizing pole will move synchronously. Through the cooperation of the linkage rod and the synchronization rod, and the cooperation of the synchronization rod and the U-shaped frame, the stabilizing collar is moved vertically on the pole by using the U-shaped frame. By adjusting the position of the stabilizing collar, the insulating crossarm is ensured to be in a stable state after the adjustment, which greatly improves the performance of the crossarm assembly.

[0022] 4. This invention, through the coordinated use of adjustment components, drive components, positioning components and stabilizing components, can achieve precise adjustment of the position of insulators and insulated crossarms to adapt to different installation conditions and requirements, while ensuring the stability of the crossarm assembly on the pole, thus improving the overall reliability and versatility.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 This invention relates to a crossarm assembly for power construction, comprising a sleeved crossarm 1 installed on a power pole, an upper fastening bolt 2 threadedly installed on the side end face of the sleeved crossarm 1, an adjustment assembly provided on the sleeved crossarm 1, an insulating crossarm 3 provided on the adjustment assembly, a drive assembly provided on the insulating crossarm 3, a U-shaped frame plate 4 fixedly installed on the lower end face of the insulating crossarm 3, a stabilizing frame rod 5 fixedly installed on the side end face of the U-shaped frame plate 4, a positioning assembly provided at the bottom end of the stabilizing frame rod 5, a stabilizing sleeve plate 6 provided on the positioning assembly, and a lower fastening bolt 7 threadedly installed on the side end face of the stabilizing sleeve plate 6. The sleeved crossarm 1 and the stabilizing sleeve plate 6 are sleeved on the power pole, and then the sleeved crossarm 1 and the stabilizing sleeve plate 6 are fixed on the power pole by the upper fastening bolt 2 and the lower fastening bolt 7.

[0034] The adjustment assembly includes an adjustment groove 8 and a translation groove 9 formed on the sleeved cross plate 1. A bearing 10 is fixedly installed on the adjustment groove 8, and an adjustment screw 11 is fixedly installed on the bearing 10. An adjustment wrench 12 is fixedly installed at one end of the adjustment screw 11. An adjustment cross plate 13 is slidably installed inside the translation groove 9. The other end of the adjustment screw 11 extends into the translation groove 9 and is movably installed with the adjustment cross plate 13. The drive assembly includes a bearing 14 fixedly installed on the insulating crossarm 3, a worm gear 15 fixedly installed on the bearing 14, a drive wrench 16 fixedly installed at the top of the worm gear 15, a support plate 17 fixedly installed on the lower end face of the insulating crossarm 3, a mounting shaft 18 rotatably installed on the support plate 17, a worm gear 19 fixedly installed on the mounting shaft 18, a T-shaped shaft 20 fixedly installed on the side end face of the worm gear 19, a sliding groove 21 formed on the insulating crossarm 3, and a sliding block 22 slidably installed inside the sliding groove 21. An mounting plate 23 is fixedly installed on the upper end face of the sliding block 22, and an insulator 24 is fixedly installed on the mounting plate 23. A connecting frame 25 is fixedly installed on the bottom end of the sliding block 22, and a drive rod 26 is rotatably installed on the connecting frame 25. The worm 15 meshes with the worm wheel 19. The end of the drive rod 26 away from the connecting frame 25 is rotatably installed on the T-shaped shaft 20. The drive rod 26 is arranged at an angle. The bottom end of the worm 15 is rotatably installed on the U-shaped frame plate 4. An adjusting screw hole is opened on the side end face of the adjusting horizontal plate 13. The adjusting screw hole and the adjusting screw rod 11 are used to ensure that the adjusting screw rod 11 can drive the adjusting horizontal plate 13 to slide in the translation groove 9 when rotating. The position of the adjusting groove 8 is inside the translation groove 9. The worm wheel 19 will not rotate more than 90 degrees. It is only necessary to ensure that the worm wheel 19 can drive the sliding block 22 to move horizontally when rotating. At the same time, the worm 15 and the worm wheel 19 have a self-locking function to prevent reverse rotation.

[0035] In this embodiment, when it is necessary to adjust the position of the insulator 24 on the insulating crossarm 3, the adjusting screw 11 is rotated by the adjusting wrench 12. The adjusting plate 13 on the adjusting screw 11 will be limited by the translation groove 9, thereby adjusting the insulating crossarm 3 on the adjusting plate 13. The insulator 24 on the insulating crossarm 3 will move synchronously with the insulating crossarm 3 in the left and right directions. At the same time, the worm gear 15 is rotated by the driving wrench 16. The worm gear 15 and the worm wheel 19 are used to drive the driving rod 26 on the T-shaped shaft 20 when the worm wheel 19 is rotated. The driving rod 26 is used to cooperate with the connecting frame 25, the connecting frame 25 is used to cooperate with the sliding block 22, and the sliding block 22 is used to limit the sliding between the sliding groove 21, thereby completing the forward and backward movement of the insulator 24. The adjustable insulator 24 can adapt to different installation conditions or working conditions, improving the versatility of the crossarm assembly.

[0036] The positioning assembly includes a positioning groove 27 formed on the stabilizing sleeve plate 6, a positioning slider 28 slidably installed inside the positioning groove 27, a movable groove 29 formed inside the stabilizing sleeve plate 6, a positioning connecting plate 30 slidably installed inside the movable groove 29, a positioning screw 31 rotatably installed on the stabilizing sleeve plate 6, a lower gear 32 fixedly installed at one end of the positioning screw 31, an upper gear 33 fixedly installed on the positioning screw 31, one end of the stabilizing rod 5 away from the U-shaped frame plate 4 fixedly installed on the positioning slider 28, and the other end of the positioning screw 31 extending into the movable groove 29. The positioning screw 31 and the positioning connecting plate 30 are movably installed. The lower gear 32 and the upper gear 33 are driven by a chain, wherein the chain is located outside the stabilizing rod 5, and when the position of the stabilizing rod 5 changes, it will not affect the movement of the chain.

[0037] In this embodiment, when the adjusting screw 11 rotates, it drives the upper gear 33 to rotate synchronously. When the upper gear 33 rotates, it drives the lower gear 32 to rotate synchronously via the chain. When the lower gear 32 rotates, it drives the positioning screw 31 to rotate. The positioning plate 30 on the positioning screw 31 slides within the movable groove 29 through the limiting sliding between the positioning slider 28 and the positioning groove 27. The movement of the positioning plate 30 drives the stabilizing rod 5 on the positioning slider 28 to move synchronously. By using the stabilizing rod 5, which can be adjusted synchronously with the insulating crossarm 3, the stability of the insulating crossarm 3 on the pole is effectively improved.

[0038] The side end face of the stabilizing pole 5 is provided with a stabilizing component, which includes a stabilizing crossbar 34 fixedly installed on the stabilizing pole 5, a linkage rod 35 fixedly installed on the stabilizing crossbar 34, a positioning ring 36 fixedly installed on the linkage rod 35, a synchronizing rod 37 fixedly installed on the linkage rod 35 and inside the positioning ring 36, a U-shaped connecting frame 38 rotatably installed at the end of the synchronizing rod 37 away from the stabilizing crossbar 34, and a stabilizing collar 39 fixedly installed on the side end face of the U-shaped connecting frame 38. The linkage rod 35 is arranged at an angle, and the stabilizing collar 39 is sleeved on the pole. When the stabilizing crossbar 34 moves synchronously with the stabilizing pole 5, the stabilizing collar 39 on the U-shaped connecting frame 38 moves vertically on the pole, wherein the friction between the stabilizing collar 39 and the pole is small.

[0039] In this embodiment, when the stabilizing rod 5 moves synchronously with the U-shaped frame plate 4 on the insulating crossarm 3, the linkage rod 35 on the stabilizing rod 5 will move synchronously. Through the cooperation of the linkage rod 35 and the synchronization rod 37, and the cooperation of the synchronization rod 37 and the U-shaped connecting frame 38, the stabilizing collar 39 can be moved vertically on the pole by using the U-shaped connecting frame 38. By adjusting the position of the stabilizing collar 39, the insulating crossarm 3 is ensured to be in a stable state after the adjustment, which greatly improves the performance of the crossarm assembly.

[0040] Working Principle: In use, when the position of the insulator 24 on the insulating crossarm 3 needs to be adjusted, the adjusting screw 11 is rotated by the adjusting wrench 12. The adjusting plate 13 on the adjusting screw 11 will be limited by the translation groove 9, thereby adjusting the insulating crossarm 3 on the adjusting plate 13. The insulator 24 on the insulating crossarm 3 will move synchronously with the insulating crossarm 3 in the left and right directions. Simultaneously, the worm gear 15 is rotated by the drive wrench 16. The worm gear 15, in cooperation with the worm wheel 19, drives the drive rod 26 on the T-shaped shaft 20. The drive rod 26, in cooperation with the connecting frame 25, the connecting frame 25 with the sliding block 22, and the sliding block 22 with the sliding groove 21, all contribute to the forward and backward movement of the insulator 24. The adjustable insulator 24 can adapt to different installation conditions or working requirements. When the adjusting screw 11 rotates, it drives the upper gear 33 to rotate synchronously. The chain drives the lower gear 32 to rotate synchronously. When the lower gear 32 rotates, it rotates through the positioning screw 31. The positioning plate 30 on the positioning screw 31 slides within the movable groove 29 through the limiting sliding between the positioning slider 28 and the positioning groove 27. The movement of the positioning plate 30 drives the stabilizing rod 5 on the positioning slider 28 to move synchronously. The stabilizing rod 5, which can be adjusted synchronously with the insulating crossarm 3, effectively improves the stability of the insulating crossarm 3 on the pole. When the stabilizing rod 5 moves synchronously with the U-shaped frame plate 4 on the insulating crossarm 3, the linkage rod 35 on the stabilizing rod 5 will move synchronously. Through the cooperation of the linkage rod 35 and the synchronization rod 37, and the cooperation of the synchronization rod 37 and the U-shaped connecting frame 38, the stabilizing collar 39 can be moved vertically on the pole by the U-shaped connecting frame 38. By adjusting the position of the stabilizing collar 39, the insulating crossarm 3 is ensured to be in a stable state after the adjustment, which greatly improves the performance of the crossarm assembly.
