Description

Technical Field

[0001] The invention relates to the technical field of cable tensioners, and in particular to a portable cable tensioner for reinforcing electric poles. Background Art

[0002] The wire tensioner, also known as the ratchet tensioner, is used to tighten the conductor during the construction of overhead line laying. When in use, first loosen the wire rope or galvanized iron wire on the wire tensioner and fix it on the crossarm, clamp the conductor with a wire clamp, and then pull the special wrench to tighten the wire. Due to the anti-reversal effect of the pawl, gradually wrap the wire rope around the ratchet drum to tighten the conductor, and fix the tightened conductor on the insulator. Then release the ratchet first to loosen the wire rope or galvanized iron wire, then release the wire clamp, and finally wrap the wire rope or galvanized iron wire around the ratchet drum to complete the wire tightening effect.

[0003] The prior art discloses a portable tensioner for reinforcing electric poles with announcement number CN205429588U. The tensioner is easy for workers to carry, has a good effect in tightening electric wires, and has high work efficiency. The tensioner can be easily folded, and the folded tensioner occupies a small space. When in use, it only needs to be straightened. The tensioner is simple to use, has a compact structure, a long service life, and is not prone to breakage and other adverse conditions. One end of the hand rod is set as a "mountain" shaped structure, so that the folding rod can only run in one direction, and the folded folding rod is directly connected with a spring buckle.

[0004] Although it is convenient for workers to carry, there are still some defects in actual use. Since most of the poles are installed in the fields, the workers' hands will inevitably be stuck with mud during the installation process, especially when they are installed on the ground after rain. Therefore, when pulling out the rope on the tensioner during the reinforcement of the pole, the mud on the workers' hands will inevitably stick to the rope. If the tensioner is used directly, the wound rope will be covered with mud, which is not convenient to carry and easy to dirty other things. Therefore, workers are required to clean the mud on the rope before tightening the line, which is not only time-consuming and labor-intensive, but also greatly reduces the construction efficiency of the device.

[0005] Therefore, a portable tensioner for electric pole reinforcement is proposed to solve the above technical problems. Summary of the invention

[0033] The driving mechanism includes a winding disk 11, which is rotatably connected to the outer wall of the frame 1 and away from the ratchet mechanism 3. The winding roller 2 is fixedly connected to a top rod 12 through the frame 1 on the side away from the ratchet mechanism 3. A pull rope 13 is wound around the outer wall of the winding disk 11, and one end of the pull rope 13 is fixedly connected to the outer wall of the winding disk 11. A rack 14 meshing with the gear ring 9 is slidably connected to the top of the fixed plate 7. A scraping mechanism is provided below the cylinder 8, and an intermittent transmission mechanism is provided on the winding disk 11.

[0034] The intermittent transmission mechanism includes a bottom plate 16, which is fixedly connected to the inner side of the winding disk 11, a through slot 15 is provided on the side wall of the frame 1 at a position corresponding to the rack 14, and the other end of the pull rope 13 passes through the through slot 15 and is fixedly connected to the side wall of the rack 14, a straight rod 17 is slidably connected to the side wall of the bottom plate 16, and an upper spring 18 is fixedly connected between the outer wall of the straight rod 17 and the side wall of the bottom plate 16, an inward groove 22 is provided on the side wall of the frame 1, an inward groove 19 is provided on the top of the fixed plate 7, a sliding plate 20 is fixedly connected to the bottom of the rack 14, and the sliding plate 20 is slidably connected to the inner side of the groove 19, and a lower spring 21 is fixedly connected between the inner side of the groove 19 and the side wall of the sliding plate 20, both ends of the groove 22 are inclined to facilitate the sliding in and out of the straight rod 17, and the groove 22 is provided on the rotation trajectory of the straight rod 17, and the end of the straight rod 17 is provided with a smooth arc surface;

[0035] In order to increase the service life of the device, a protective cover 23 is fixedly connected to the side wall of the frame 1 and is located on the outside of the winding drum 11. Through the setting of the protective cover 23, the outside of the winding drum 11 can be shielded to improve the protection effect of the device, and the side wall of the frame 1 is rotatably connected to an upper guide roller 24 and is located below the winding drum 11. The inner side of the through groove 15 is rotatably connected to a lower guide roller 25, and the pull rope 13 passes through the outer walls of the upper guide roller 24 and the lower guide roller 25 respectively. Through the setting of the upper guide roller 24 and the lower guide roller 25, the movement of the pull rope 13 can be guided, and at the same time, the pull rope 13 can be prevented from directly contacting the corner to cause wear, affecting the service life of the pull rope 13, thereby reducing the service life of the device.

[0036] In order to automatically clean up the dirt scraped by the scraper 10, the scraping mechanism includes a scraper plate 26, an annular groove 27 is provided at the bottom of the cylinder 8, a volute spring 28 is provided inside the annular groove 27, and one end of the volute spring 28 is fixedly connected to the inside of the annular groove 27, an annular plate 29 is rotatably connected to the bottom of the annular groove 27, and the other end of the volute spring 28 is fixedly connected to the top of the annular plate 29, an adjusting frame 30 is fixedly connected to the bottom of the annular plate 29, and the scraper plate 26 is slidably connected to the inside of the adjusting frame 30, and a limit plate 31 for limiting the rotation position of the adjusting frame 30 is fixedly connected to the bottom of the fixed plate 7 and located on both sides of the cylinder 8, and the top of the scraper plate 26 is in contact with the bottom end of the scraper plate 10;

[0037] In the process of winding the tensioner, the winding roller 2 is driven by rotating the handle on the ratchet mechanism 3, and then the cylinder 8 is driven to rotate under the drive of the driving mechanism, and the adjusting frame 30 at the bottom is driven to rotate. Then the adjusting frame 30 rotates 180 degrees and is blocked by the limit plate 31, and then the cylinder 8 continues to rotate, so that the scraper plate 26 can clean the dirt on the surface of the scraper 10 that continues to rotate. At the same time, through the rotation of the cylinder 8, one end of the volute spring 28 is fixed in the annular groove 27, and the other end is fixed in the annular groove 27. The top of the plate 29 will gradually compress or expand the volute spring 28, and then gradually push the volute spring 28 to reset when the cylinder 8 is reset, thereby increasing the pulling force through the volute spring 28 to ensure that the position of the scraper plate 26 remains unchanged, and the above operation is repeated when moving in the reverse direction. When using the tensioner, the contact end of the limit plate 31 and the adjustment frame 30 can be placed downward for use, so that under the action of gravity, the soil on the scraper plate 26 will fall to the ground as more and more soil is scraped off, reducing the scope of manual cleaning and improving the convenience of the device.

[0038] In order to adjust the position of the scraper plate 26 according to ropes 4 of different specifications, an adjustment spring 32 is fixedly connected between the inner side of the adjustment frame 30 and the side wall of the scraper plate 26. Through the setting of the adjustment spring 32, when cleaning ropes 4 of different specifications, the scraper plate 26 can be pushed or squeezed under the elastic force of the adjustment spring 32 to ensure that the scraper plate 26 is in close contact with the side wall of the rope 4, thereby improving the cleaning effect on the bottom of the scraper 10.

[0039] In order to be able to use ropes 4 of different specifications, an adjusting ring 33 is rotatably connected to the inner side of the gear ring 9, a pair of arc grooves 34 are provided on the top of the adjusting ring 33, and the radius between the two ends of the arc groove 34 is different, a round rod 35 is fixedly connected to the top of the scraper 10, and the top of the round rod 35 is arranged on the inner side of the arc groove 34, and a limiting mechanism for limiting the rotation of the adjusting ring 33 is provided on the gear ring 9, and a positioning ring 36 is fixedly connected to the inner side of the cylinder 8, and a straight groove 37 is provided on the top of the positioning ring 36 and at a position corresponding to the round rod 35, and the round rod 35 is slidably connected to the inner side of the straight groove 37. Through the setting of the positioning ring 36 and the straight groove 37, the sliding position of the round rod 35 can be limited during the adjustment process, so as to prevent the round rod 35 from rotating with the adjusting ring 33, thereby affecting the normal adjustment of the spacing between the scrapers 10 and improving the stability of the device during operation;

[0040] The limiting mechanism includes an arc plate 38, which is fixedly connected to the top of the gear ring 9, and a plurality of jacks 39 are equidistantly provided on the side wall of the arc plate 38. A support plate 40 is fixedly connected to the top of the adjusting ring 33, and a limiting rod 41 is slidably connected to the side wall of the support plate 40, and the end of the limiting rod 41 is inserted into the inner side of one of the jacks 39, and a limiting spring 42 is fixedly connected between the side wall of the support plate 40 and the outer wall of the limiting rod 41;

[0041] When the rope 4 is damaged due to long-term use or a rope 4 of different thickness needs to be replaced according to demand, the limit rod 41 can be pulled outward to slide out of the insertion hole 39 to release the rotation restriction of the adjusting ring 33 and compress the limit spring 42 at the same time, so that the limit rod 41 can be rotated to drive the adjusting ring 33 to rotate. Since the end of the round rod 35 is arranged in the arc groove 34, and the radii of the two ends of the arc groove 34 on the adjusting ring 33 are different, the adjusting ring 33 is rotated and the round rod 35 is pushed to slide on the inner side of the straight groove 37 under the extrusion of the arc groove 34, and the two scrapers 10 at the bottom are driven to move in a direction close to or away from each other, so as to adjust the distance between the scrapers 10. Therefore, ropes 4 of different specifications can be used, and the application range of the device is improved. Finally, the limit rod 41 can be released after the adjustment is completed, and then the limit rod 41 is pulled to slide into the corresponding insertion hole 39 under the elastic force of the limit spring 42, that is, the rotation position of the adjusting ring 33 is fixed, and the adjustment of the distance between the scrapers 10 is completed.

[0042] In the process of reinforcing the electric pole, the handle on the ratchet mechanism 3 is rotated to drive the winding roller 2 to wind up, and the rope 4 is provided with tension to achieve the tightening effect of the electric pole tension wire. At the same time, the rotation of the winding roller 2 will drive the top rod 12 to rotate, and then the top rod 12 moves to the side of the straight rod 17, thereby pushing the straight rod 17 to drive the winding disk 11 to rotate. At this time, the straight rod 17 is resisted by the side wall of the frame 1 and cannot move, so that the pull rope 13 is wound up by the rotation of the winding disk 11;

[0043] Since one end of the pull rope 13 is fixed on the winding disk 11, the pull rope 13 is pulled to move, which in turn drives the rack 14 and the sliding plate 20 fixed on the other end of the pull rope 13 to slide inside the slide groove 19, and then drives the meshing gear ring 9 to rotate. Since the round rod 35 on the scraper 10 slides in the straight groove 37, the gear ring 9 drives the cylinder 8 to rotate, which drives the scraper 10 on the outside of the rope 4 to rotate at the same time, and gradually stretches the lower spring 21, and then the top rod 12 pushes the straight rod 17 to the groove. 22, and then under the elastic force of the upper spring 18, the straight rod 17 is pushed to slide into the groove 22, and then the straight rod 17 slides away from the top rod 12. At this time, the thrust of the top rod 12 is lost, and the rack 14 is pulled to reset under the elastic force of the lower spring 21, and the cylinder 8 is driven to rotate in the opposite direction, and the reverse direction is achieved. At the same time, the winding of the rope 4 is coordinated with the winding roller 2 to realize the cleaning of the mud on the outer wall of the rope 4 during the winding process, and no manual cleaning is required, which not only makes it easy to carry the tensioner, but also improves the convenience of the device.

[0044] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
