Description

Technical Field

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

[0002] Power poles, also known as utility poles or electric poles, are tower structures used to support power lines. They play a vital role in the power system, ensuring that electricity can be safely and stably transmitted to all users.

[0003] In existing technologies, modular power poles are a widely used method of power pole installation. Modular power poles are manufactured in sections, and flanges are installed at both ends and on the pole body. After the sections of the power pole and the crossarms to be installed are transported to the construction site, bolts are inserted into the pre-drilled holes on the flanges at both ends of the power pole, anti-slip pads are placed on the bolts, and then nuts are tightened to complete the assembly of the power pole. The invention of modular power poles has greatly reduced the difficulty and cost of transporting power poles.

[0004] However, in existing technology, the connection between the two ends of the power pole is accomplished by bolts and nuts. The anti-loosening mechanism between the bolts and nuts is achieved by compressing the washer after tightening the nut. The reaction force of the washer on the nut creates a large compressive force between the threads of the nut and the bolt, which in turn generates a large frictional force to prevent loosening. However, power poles operate outdoors for extended periods in harsh temperature and humidity environments. The thermal expansion and contraction caused by large temperature differences and the moisture caused by high humidity can both reduce or even eliminate the frictional force between the threads. Over time, this can cause the nuts to loosen, making the installation of the combined power pole less secure. Utility Model Content

[0005] The purpose of this invention is to provide a combined power pole to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined power pole, comprising: a power pole, a flange fixed to the end of the power pole, a screw hole formed on the surface of the flange, a screw rod movably inserted into the screw hole, a washer fitted on the body of the screw rod, and a nut connected to the body of the screw rod by a threaded connection, an anti-loosening sleeve mounting groove formed on the surface of the flange, one end of an anti-loosening sleeve movably inserted into the anti-loosening sleeve mounting groove, the other end of the anti-loosening sleeve extending out from the anti-loosening sleeve mounting groove, the anti-loosening sleeve having a ring structure, and the nut and screw cap of the screw rod being movably inserted into the inner ring of the anti-loosening sleeve.

[0007] Preferably, one end of the anti-loosening sleeve extending into the anti-loosening sleeve mounting groove is fixed with an anti-loosening spring, and the other end of the anti-loosening spring is fixed to the inner wall of the anti-loosening sleeve mounting groove.

[0008] Preferably, a limiting groove is formed on the outer ring surface of the anti-loosening sleeve, and a limiting rod mounting groove is formed on the inner wall of the anti-loosening sleeve mounting groove. One end of the limiting rod is movably inserted into the limiting rod mounting groove, and the other end of the limiting rod is movably inserted into the limiting groove.

[0009] Preferably, a pull rod is movably inserted into the surface of the flange, one end of the pull rod extends into the mounting groove of the limiting rod and is fixed to the surface of the limiting rod, and the other end of the pull rod is rotatably connected to a pull ring.

[0010] Preferably, a limiting spring is sleeved on the rod body of the pull rod, with one end of the limiting spring abutting against the surface of the limiting rod and the other end of the limiting spring abutting against the inner wall of the groove of the limiting rod mounting slot.

[0011] Preferably, a pull ring groove is formed on the surface of the flange, and the pull ring is movably connected in the pull ring groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The combined power pole proposed in this utility model involves inserting the nut of the screw into an anti-loosening sleeve provided on the surface of one set of flanges. Then, a gasket is placed on the screw and the nut is tightened. Before tightening the nut, the anti-loosening sleeve closest to the nut is fully pressed into the anti-loosening sleeve mounting groove to prevent the anti-loosening sleeve from obstructing the tightening of the nut. After the nut is slightly tightened, continue to tighten the nut in the tightening direction until the nut is aligned with the inner ring of the anti-loosening sleeve. Then, one end of the anti-loosening sleeve extends from the anti-loosening sleeve mounting groove and is placed on the surface of the nut, while the other end remains in the anti-loosening sleeve mounting groove. This set of anti-loosening sleeves provides circumferential restraint for the nut, and the other set of anti-loosening sleeves provides circumferential restraint for the screw nut, thus providing circumferential restraint for the screw. Both the screw and the nut are circumferentially restrained, completely eliminating relative movement between the screw and the nut, ensuring that the threaded connection between the screw and the nut will not loosen due to harsh temperature and humidity environments.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example 1: Please refer to Figures 1 to 3 This utility model provides a technical solution: a combined power pole, comprising: a power pole 1, a flange 2 fixed to the end of the power pole 1, a screw hole 3 on the surface of the flange 2, a screw 4 movably inserted into the screw hole 3, a washer 6 fitted on the body of the screw 4, and a nut 5 threadedly connected to the body of the screw 4; an anti-loosening sleeve mounting groove 7 on the surface of the flange 2, one end of an anti-loosening sleeve 8 movably inserted into the anti-loosening sleeve mounting groove 7, the other end of the anti-loosening sleeve 8 extending out of the anti-loosening sleeve mounting groove 7, the anti-loosening sleeve 8 having a ring structure, the nut and the screw 4 being movably inserted into the inner ring of the anti-loosening sleeve 8, an anti-loosening spring 9 fixed to one end of the anti-loosening sleeve 8 extending into the anti-loosening sleeve mounting groove 7, and the other end of the anti-loosening spring 9 fixed to the inner wall of the anti-loosening sleeve mounting groove 7.

[0020] In actual use, when combining two sets of power poles 1, align several sets (3) on the surfaces of the two sets of flanges 2 one by one, then insert several sets of screws 4 into the aligned sets of screw holes 3 respectively, and insert the nuts of the screws 4 into the anti-loosening sleeves 8 set on the surface of one set of flanges 2. Then, put the gaskets 6 on the screws 4 and tighten the nuts 5. Before tightening the nuts 5, press the anti-loosening sleeves 8 near the nuts 5 completely into the anti-loosening sleeve mounting grooves 7 to prevent the anti-loosening sleeves 8 from hindering the turning of the nuts 5. After the nuts 5 are slightly tightened, continue to turn the nuts 5 in the tightening direction so that the nuts are tightened. Align the inner ring of the anti-loosening sleeve 8 with the nut 5, and then let one end of the anti-loosening sleeve 8 extend out of the anti-loosening sleeve mounting groove 7 and be fitted onto the surface of the nut 5. The other end of the anti-loosening sleeve 8 stays in the anti-loosening sleeve mounting groove 7. This set of anti-loosening sleeves 8 then plays a circumferential limiting role for the nut 5. The other set of anti-loosening sleeves 8 plays a circumferential limiting role for the nut of the screw 4, and thus plays a circumferential limiting role for the screw 4. Both the screw 4 and the nut 5 are circumferentially limited, thereby completely eliminating the relative movement between the screw 4 and the nut 5, so that the threaded connection between the screw 4 and the nut 5 will not loosen due to harsh temperature and humidity environments.

[0021] Example 2: Based on Example 1, in order to completely limit the anti-loosening sleeve 8 in the anti-loosening sleeve mounting groove 7 when tightening the nut 5, after tightening the nut 5, one end of the anti-loosening sleeve 8 is allowed to extend out of the anti-loosening sleeve mounting groove 7. A limiting groove 10 is formed on the outer ring surface of the anti-loosening sleeve 8, and a limiting rod mounting groove 11 is formed on the inner wall of the groove 7. One end of the limiting rod 12 is movably inserted into the limiting rod mounting groove 11, and the other end of the limiting rod 12 is movably inserted into the limiting groove 10. A pull rod 14 is movably inserted into the surface of flange 2. One end of the pull rod 14 extends into the limiting rod mounting groove 11 and is fixed to the surface of the limiting rod 12. The other end of the pull rod 14 is rotatably connected to a pull ring 15. A limiting spring 13 is sleeved on the rod body of the pull rod 14. One end of the limiting spring 13 abuts against the surface of the limiting rod 12, and the other end of the limiting spring 13 abuts against the inner wall of the groove of the limiting rod mounting groove 11. A pull ring groove 16 is opened on the surface of flange 2, and the pull ring 15 is movably connected in the pull ring groove 16.

[0022] When tightening nut 5, the anti-loosening sleeve 8 is fully pressed into the anti-loosening sleeve mounting groove 7. After pressing, the limiting groove 10 is aligned with the limiting rod mounting groove 11. The thrust generated by the compressed limiting spring 13 on the limiting rod 12 pushes one end of the limiting rod 12 into the limiting groove 10, while the other end of the limiting rod 12 remains in the limiting rod mounting groove 11, thus completely limiting the anti-loosening sleeve 8 in the anti-loosening sleeve mounting groove 7. At this time, the anti-loosening spring 9 is compressed. After tightening nut 5, the pull ring 15 is pulled from the pull ring. The ring is removed from the groove 16, and then the pull rod 14 is pulled outward. The pull rod 14 drives the limiting rod 12, causing the limiting rod 12 to exit from the limiting groove 10 and then fully retract into the limiting rod mounting groove 11. The limiting of the anti-loosening sleeve 8 is released, and the pushing force of the anti-loosening spring 9 on the anti-loosening sleeve 8 pushes one end of the anti-loosening sleeve 8 out of the anti-loosening sleeve mounting groove 7. A pull ring groove 16 is opened on the surface of the flange 2. During the transportation of the power pole 1, the pull ring 15 is stored in the pull ring groove 16 to prevent collisions.

[0023] In actual use, when combining two sets of power poles 1, align several sets (3) on the surfaces of the two sets of flanges 2 one by one, then insert several sets of screws 4 into the aligned sets of screw holes 3 respectively, and insert the nuts of the screws 4 into the anti-loosening sleeves 8 set on the surface of one set of flanges 2. Then, put the gaskets 6 on the screws 4 and tighten the nuts 5. Before tightening the nuts 5, press the anti-loosening sleeves 8 near the nuts 5 completely into the anti-loosening sleeve mounting grooves 7 to prevent the anti-loosening sleeves 8 from hindering the turning of the nuts 5. When the nuts 5 are slightly tightened After tightening, continue to tighten nut 5 in the tightening direction until nut 5 is aligned with the inner ring of anti-loosening sleeve 8. Then, let one end of anti-loosening sleeve 8 extend from the anti-loosening sleeve mounting groove 7 and fit onto the surface of nut 5, while the other end of anti-loosening sleeve 8 remains in the anti-loosening sleeve mounting groove 7. This set of anti-loosening sleeves 8 then acts as a circumferential limiter for nut 5, and the other set of anti-loosening sleeves 8 acts as a circumferential limiter for the nut of screw 4, thereby also acting as a circumferential limiter for screw 4. Both screw 4 and nut 5 are circumferentially limited, thus completely preventing screw 4 and nut 5 from moving together. The movement ensures that the threaded connection between the screw 4 and the nut 5 will not loosen due to harsh temperature and humidity environments. When tightening the nut 5, the anti-loosening sleeve 8 is fully pressed into the anti-loosening sleeve mounting groove 7. After pressing, the limiting groove 10 aligns with the limiting rod mounting groove 11. The thrust generated by the compressed limiting spring 13 on the limiting rod 12 pushes one end of the limiting rod 12 into the limiting groove 10, while the other end of the limiting rod 12 remains in the limiting rod mounting groove 11, thus completely limiting the anti-loosening sleeve 8 in the anti-loosening sleeve mounting groove 7. At this time, the anti-loosening spring 9 is... Compression; after tightening nut 5, pull ring 15 is pulled out of pull ring groove 16, and then pull rod 14 is pulled outward. Pull rod 14 drives limit rod 12, so that limit rod 12 exits from limit groove 10 and retracts completely into limit rod mounting groove 11. Then the limit of anti-loosening sleeve 8 is released, and the thrust of anti-loosening spring 9 on anti-loosening sleeve 8 pushes one end of anti-loosening sleeve 8 out of anti-loosening sleeve mounting groove 7; pull ring groove 16 is opened on the surface of flange 2. During the transportation of power pole 1, pull ring 15 is stored in pull ring groove 16 to prevent collision.
