Description

Technical Field

[0001] The invention relates to the field of electric wire brackets, in particular to a portable electric wire bracket suitable for electric power engineering. Background Art

[0002] The power line bracket is used to install cables. The bracket is fixed on the wall or the electric pole, and then the cables to be installed are fixed on the bracket.

[0003] The existing Chinese public document (CN117543435A) records a portable power line bracket for power engineering and its use method. The public scheme records that when installing the cable, the mounting bracket is fixedly installed on the installation position for laying the cable, and then the cable is inserted through the through-holes on the mounting bracket and the load-bearing clamping device. When the cable is inserted through the through-hole on the mounting bracket, the outer wall of the cable contacts the elastic clamping frame, and the elastic clamping frame will limit the movement of the cable. At this time, if the cable needs to be fixed to the mounting bracket, the mobile frame is moved on the two support rods so that the through-hole on the mobile frame passes through the cable. At this time, the wedge-shaped elastic clamping frame will contact the inner wall of the through-hole on the mobile frame, and then when the mobile frame moves closer to the mounting bracket, the cable on the mobile frame will be clamped more tightly, and the mobile frame can be limited by the contact between the ratchet and the card strip on the mobile frame, thereby realizing the initial fixation during the cable laying process.

[0004] In the public scheme, the installation of the cable is to pass the cable through the through-hole for erection and fixation. Because the bracket for erecting the cable is generally used in conjunction with multiple brackets, the cable is erected at multiple points, and the cable is generally erected at high altitude. If the cable is erected through the through-hole on the bracket in sequence, this method is only suitable for the erection of shorter cables. Because if the cable is long, the entire cable is very laborious in the process of unfolding and moving, and it is also necessary to work at high altitude to let the ends of the cable pass through the through-hole in sequence. There is also a large friction between the insulation layer on the surface of the cable and the through-hole. Therefore, the erection method in the above public scheme is extremely laborious and is not suitable for long-distance cable erection. Moreover, the actual erection construction of long-distance cables is hung through the bracket, that is, the operator only needs to pull the cable on the ground. When the cable is laid directly under the bracket, when the cable is temporarily laid, the operator can hang the cable on the bracket through the hook, but this hanging method is not strong for the stability of the cable.

[0020] Example 1: Please refer to Figure 1-Figure 8 , a portable power line bracket suitable for power engineering shown in the figure comprises: a bracket plate 1 for fixing on a wall or a power pole, and a connecting plate 2 is fixedly mounted on the end face of the bracket plate 1 through a connecting rod, and a hanging component is arranged on one end face of the connecting plate 2 away from the bracket plate 1, and the hanging component comprises two symmetrically distributed limiting plates 3, one of which is fixed to the connecting plate 2, and a plurality of arc plates 4 which are equidistantly distributed in a straight line are fixedly mounted between the bottoms of the two limiting plates 3, and a plurality of balls 5 are rotatably mounted between two adjacent arc plates 4, and a cover plate 6 is covered on the top of the two limiting plates 3, and a rotating shaft 7 is fixedly inserted on the cover plate 6 close to one end face of the bracket plate 1, and the rotating shaft 7 is rotatably inserted on the top of a limiting plate 3 fixed to the connecting plate 2 at the same time; It also includes: a fixing unit, which is used to fix the cables hung inside the hanging component, the fixing unit is located outside the cover plate 6, and a driving unit is also arranged inside the fixing unit; The auxiliary support unit is used to assist the fixing unit in supporting the cables, and the auxiliary support unit is located outside the fixing unit.

[0021] The cover plate 6 has the function of turning 180° on the top of the limit plate 3 through the rotating shaft 7. The fixing unit includes a cover frame 15 located at one end face away from the limit plate 3 when the cover plate 6 is covered, and the cover frame 15 is fixed to the cover plate 6. The inside of the cover frame 15 and the cover plate 6 are transparent. The end face of the cover plate 6 away from the limit plate 3 is threadedly assembled with a threaded rod 16, and the end of the threaded rod 16 extending into the cover frame 15 is rotatably sleeved with a sleeve disc 17. A pressing frame 19 is also provided inside the cover frame 15, and the sleeve disc 17 is away from the threaded rod 16. A first spring 18 is fixedly arranged between one end of the grooved rod 16 and the pressing frame 19, and two symmetrically distributed limit frames 27 are fixedly arranged at the end of the pressing frame 19 away from the first spring 18. A rotating column is rotatably arranged inside each limit frame 27, and a scattered tooth column 28 is fixedly mounted on the outer surface of the rotating column. A connecting piece is arranged between the movable end of the cover plate 6 and the other limit plate 3. When the cover plate 6 covers the upper end surfaces of the two limit plates 3, the cable can be pressed onto the ball 5 through the scattered tooth column 28.

[0022] The connecting piece is a detachable screw or a detachable lock, that is, the cover plate 6 and the limiting plate 3 can be conveniently locked and unlocked through the connecting piece.

[0023] The limiting frame 27 is inclined, and the outer surface of the scattered tooth column 28 is in direct contact with the cable. The two inclined and symmetrical scattered tooth columns 28 can play a role of centering and squeezing the cable.

[0024] At least two sliders 20 are fixedly provided on the outer wall of the pressing frame 19, and the sliders 20 and the threaded rod 16 are vertically distributed, and the outer wall of the cover frame 15 is provided with straight grooves 21 for sliding assembly with the sliders 20. The sliding engagement between the sliders 20 and the straight grooves 21 is to ensure the stability of the pressing frame 19 when moving up and down.

[0025] Working principle: When it is necessary to install long-distance cables on walls or electric poles, first fix several bracket plates 1 at multiple points on the wall to carry out multi-point hanging processing. The staff first spreads the cables to be hung on the ground, and then lifts the cables through the hanging rods and hangs the cables inside the hanging parts. In this way, the cables are simply hung at multiple points. After hanging the last point, the staff can pull the cables on the ground and flatten the cables that are bent and hung between adjacent hanging parts. At this time, the staff will perform aerial operations to fix the cables inside each hanging part. The staff puts the cover plate 6 on the limit plate 3, limits the positions of the cover plate 6 and the limit plate 3 through the connecting parts, and then rotates the threaded rod 16 with a wrench, so that the threaded rod 16 moves the pressing frame 19 downward through the first spring 18, so that the two scattered tooth columns 28 can elastically press the cable, and the cable can be squeezed onto the ball 5 through the two scattered tooth columns 28, so that the cable can be fixed inside the hanging component.

[0026] Example 2: Please refer to Figure 6-Figure 8 , this embodiment is a further description of the first embodiment, the driving unit includes a second rotating column 24 rotatably assembled inside the pressing frame 19, and the second rotating column 24 is located above the two limit frames 27, and a bevel gear 26 is fixedly mounted between one end of each rotating column close to the center of the pressing frame 19 and the outer surface of the second rotating column 24, and the two bevel gears 26 located on the same side are meshed with each other, a first rotating column 22 is placed above the second rotating column 24, and the first rotating column 22 is rotatably inserted into the interior of the pressing frame 19, and the first rotating column 22 is fixedly mounted between the second rotating column 24 and the second rotating column 22. One end of the column 22 away from the bracket plate 1 movably passes through the cover frame 15, and a nut 23 is fixedly provided at one end of the first rotating column 22 away from the bracket plate 1. The outer surfaces of the first rotating column 22 and the second rotating column 24 are both sleeved with second gears 25, and a synchronous toothed belt is assembled between the two second gears 25. A limiting component is also provided on the outside of the first rotating column 22. By utilizing the cooperation of the two second gears 25 and the synchronous toothed belt, and two sets of mutually meshing bevel gears 26, the first rotating column 22 can rotate synchronously with the second rotating column 24.

[0027] The two second gears 25 distributed up and down are respectively slidably assembled and fixedly assembled with the first rotating column 22 and the second rotating column 24. The limiting component includes two first limiting frames 29 slidably sleeved on the outer surface of the first rotating column 22. The two first limiting frames 29 are fixed to the pressing frame 19, and the second gear 25 located at the top is located between the two first limiting frames 29. The two first limiting frames 29 limit the second gear 25. A limiting groove 35 is provided on the outer surface of the first rotating column 22, and the inner wall of the second gear 25 distributed at the top is slidably engaged with the limiting groove 35. A snap ring 30 is provided on the side of the second gear 25 away from the nut 23, and the snap ring 30 is fixedly sleeved on the outside of the first rotating column 22. A first stopper 30 is provided between the end of the snap ring 30 away from the nut 23 and the pressing frame 19. The second spring 31 and the second limit frame 32 are arranged on the side of the second gear 25 close to the nut 23. The second limit frame 32 is movably sleeved on the outside of the first rotating column 22, and the second limit frame 32 is fixed to the pressing frame 19. The inner wall of the second limit frame 32 is provided with a plurality of circumferentially equidistant receiving grooves 33, and the interior of each accommodating groove 33 is provided with a movable ratchet 34 which is elastically rotated by a latch and a torsion spring. The outer wall of the first rotating column 22 is also provided with an annular groove portion 36, and the outer wall of the annular groove portion 36 is fixedly provided with a plurality of circumferentially equidistant arc-shaped clamping blocks 37, a clamping groove is formed between two adjacent arc-shaped clamping blocks 37, and the clamping groove is movably engaged with the movable ratchet 34. When the movable ratchet 34 inside the accommodating groove 33 is engaged with the clamping groove, the first rotating column 22 can be limited to rotate in one direction only, and cannot rotate back.

[0028] The arc block 37 is in the shape of a pen tip, and the tip of the arc block 37 faces the nut 23 , wherein the length of the annular groove 36 is greater than the length of the arc block 37 . When the movable ratchet 34 is disengaged from the groove, the first rotating column 22 is no longer restricted by the movable ratchet 34 .

[0029] In this embodiment, the cable is flattened by pulling. However, due to the cable's own gravity and the friction between the cable and the hanging component, the cable cannot be completely flattened. The cable is still in a downward curved arc between two adjacent hanging components. Therefore, in this solution: The staff can use an electric hand screwdriver to fit the screwdriver head with the nut 23, and the electric hand screwdriver can automatically drive the first rotating column 22 to rotate. Through the action of the two second gears 25 and the synchronous toothed belt, and the action of the two sets of mutually meshing bevel gears 26, the two scattered tooth cylinders 28 can be rotated. Since the scattered tooth cylinders 28 are pressed on the surface of the cable, the friction force with the surface of the cable is large, and the cable can be driven to move on the upper part of the ball 5 through the scattered tooth cylinders 28, so that the cable between the two adjacent hanging parts can be pulled and flattened to the greatest extent; Moreover, the movable ratchet 34 restricts the slot between the two arc-shaped blocks 37, thereby preventing the first rotating column 22 from rotating, thereby ensuring the stability of the cable being fixed inside the hanging component; If the cable is too tight to be flattened by the loose-toothed column 28 and the ball 5 and needs to be loosened, the staff only needs to push the nut 23 with the screwdriver bit at the front end of the electric hand screwdriver to make the first rotating column 22 undergo a lateral displacement change, so that the movable ratchet 34 can be disengaged from between the two arc-shaped blocks 37. At this time, the first rotating column 22 is no longer subject to unidirectional limit, so that the loose-toothed column 28 can be reversed, and the flattened state of the cable can be fine-tuned to avoid excessive tension, which affects the aging speed of the rubber coating of the cable; After the adjustment is completed, the first rotating column 22 can be horizontally reset. During the reset process, the movable ratchet 34 can be quickly restrained in the slot again through the guidance of the tip of the arc-shaped clamping block 37 without difficulty in reset.

[0030] Example 3: Please refer to Figure 1-Figure 4 This embodiment is a further explanation of the above embodiment. The auxiliary support unit includes two symmetrically distributed optical axes 14 rotatably mounted inside the bracket plate 1 and the connecting plate 2. The end of the optical axis 14 away from the bracket plate 1 extends to directly below the hanging component. The outer surface of the end of each optical axis 14 away from the bracket plate 1 is fixedly sleeved with a connecting block 12, and the outer wall of the connecting block 12 is also fixedly provided with a frame 13. A trigger component is provided between each optical axis 14 and the rotating shaft 7. When the cover plate 6 is flipped over and covered on the top of the limit plate 3, the two frames 13 can be unfolded by the trigger component to provide auxiliary support for the cables.

[0031] The trigger component includes a winding wheel 8 fixedly sleeved on both ends of the rotating shaft 7, and two racks 10 are axially slidably provided on one end surface of the connecting plate 2 close to the bracket plate 1. The two racks 10 are respectively located on the outside of the two optical axes 14. The outer surface of each optical axis 14 is fixedly sleeved with a first gear 11, and the first gear 11 and the rack 10 located on the same side are movably engaged. A traction rope 9 is fixedly provided between the top of the rack 10 located on the same side and the outer wall of the winding wheel 8. The rotation of the rotating shaft 7 prompts the winding wheel 8 to reel in the traction rope 9, and the rack 10 moves upward to drive the first gear 11 to rotate with the optical axis 14.

[0032] In this embodiment, when the cover plate 6 is turned 180° and covers the upper part of the limit plate 3, the rotating shaft 7 rotates with the two winding wheels 8, and pulls the rack 10 upward through the traction rope 9. When the rack 10 moves upward, refer to the attached Figure 3In the positional relationship, the rack 10 drives the first gear 11 to rotate, so that the optical axis 14 deflects the frame 13, and the frame 13 is unfolded. The two frames 13 can support the cables on both sides of the hanging component. The two frames 13 cooperate with the hanging component to bear the pressure of the cables at the same time, which further ensures the service life of the hanging component. Moreover, after the cables are supported by the frame 13, the bending degree of the cables inside the hanging component can be reduced, making it easier for the scattered tooth column 28 to effectively squeeze the cables.
