Description

Technical Field

[0001] The present invention relates to the technical field of electric power engineering, and in particular to an auxiliary device for erecting a wire for an electric pole. Background Art

[0002] Common electric poles include wooden poles, cement poles, cast poles, power towers, etc. During the installation process, guy wires are usually used to provide auxiliary support for the poles, which can balance the forces acting on the poles from all aspects and resist wind pressure, thereby reducing the occurrence of pole tipping.

[0003] When erecting an electric pole, the pole is usually fixed to the ground first, and then a worker climbs up the pole to fix one end of the guy wire on the pole. At the same time, another worker is required to pull the guy wire from below to make it straight. The tightening and straightening of the guy wire is usually done by manpower. At the same time, since the guy wire is usually a multi-strand steel wire rope, the weight of the guy wire is heavy, and more force is needed to straighten the guy wire, which increases physical labor. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a wire-pulling auxiliary device for erecting electric poles to solve the technical problem that the wire-pulling erection work is relatively labor-intensive.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an auxiliary device for pulling wires in the erection of electric poles, comprising a device body, a friction wheel connected inside the device body, and a top wheel sleeved on the outside of the friction wheel, a spring connected inside the device body, and a brake frame connected under the spring, a gear sleeved on the outside of the brake frame, and a limit bar connected to the side of the brake frame, and a limit rod connected inside the device body.

[0006] By adopting the above technical solution, the staff can drive the friction wheel to rotate through an electric motor or a hand-cranked tool. After the friction wheel rotates, the friction force is used to transport the pull wire and thus straighten the pull wire. At the same time, the friction between the two friction wheels and the pull wire causes the two friction wheels to move toward each other, and the friction wheel drives the top wheel to rotate to push the brake frame open, thereby preventing the brake frame from contacting the pull wire and affecting the pull wire transportation. When the friction wheel is no longer driven, the brake frame is affected by the spring and fits the pull wire. At the same time, the gears are used to make the two brake frames move synchronously to hold the pull wire, and when the friction wheel drives the top wheel to reverse, the top wheel will abut against the brake frame and thus brake the friction wheel to limit the position. At this time, the pull wire is limited by the friction force between the brake frame, the friction wheel and the pull wire, and there is no need for the motor or the staff to manually apply force to the pull wire. After the pull wire is installed, the staff loosens the fastening bolts to separate the two device bodies, and then the staff can remove the lower device body by pulling out the ground nails. At this time, the brake frame is limited by the limit bar and the limit rod to prevent the brake frame from rotating outside the device body, which will cause the gears to be unable to align when the device is spliced ​​next time.

[0007] Furthermore, one end of the friction wheel is connected to a keyway shaft, a pull wire is connected inside the brake frame, two device bodies are provided, and a fastening bolt is connected between the two device bodies.

[0008] By adopting the above technical solution, the staff limits the lower device body to the ground through ground nails, and at the same time makes the pull wire located in the device body and fits with the brake frame and the friction wheel. Then the staff fits the upper device body with the lower device body and limits them by tightening the bolts. At this time, the staff connects the keyway shaft to the motor through a coupling or directly puts a hand-cranked tool on the keyway shaft. Then the staff can drive the friction wheel to rotate through the motor or hand-cranked tool.

[0009] Furthermore, the top wheel abuts against the brake frame, and the limit bar abuts against the limit rod.

[0010] By adopting the above technical solution, when the friction wheel is no longer driven, the brake frame is affected by the spring and fits with the pull wire. At the same time, the two brake frames are moved synchronously through the gears to hold the pull wire. When the friction wheel drives the top wheel to reverse, the top wheel will abut against the brake frame and thus brake the friction wheel to limit the position. After the staff removes the main body of the device, the brake frame is limited by the limit bar and the limit rod to prevent the brake frame from rotating outside the main body of the device, which will cause the gears to be unable to align when the device is spliced ​​next time.

[0011] Furthermore, the brake frame is in contact with the pull wire, and the brake frame is movably connected to the device body.

[0012] By adopting the above technical solution, when the friction wheel is no longer driven, the brake frame is affected by the spring and fits with the pull wire. At the same time, the two brake frames are moved synchronously through the gears to hold the pull wire. When the friction wheel drives the top wheel to reverse, the top wheel will abut against the brake frame and then brake the friction wheel to limit the position. At this time, the pull wire is limited by the friction force between the brake frame, the friction wheel and the pull wire, and there is no need for the motor or the staff to manually apply force to the pull wire.

[0013] Furthermore, the fastening bolt is movably connected to the device body located below, and the fastening bolt abuts against the device body located above.

[0014] By adopting the above technical solution, the staff limits the lower device body to the ground, while the pull wire is located in the device body and fits with the brake frame and the friction wheel. Then the staff fits the upper device body with the lower device body, and then the staff turns the fastening bolt and tightens the fastening bolt to limit the device body.

[0015] Furthermore, a plurality of the fastening bolts are provided, and the plurality of fastening bolts are symmetrically distributed.

[0016] By adopting the above technical solution and setting up multiple fastening bolts, the number of fastening points between the two device bodies is increased. By increasing the number of fastening points between the two device bodies, the stability of the connection between the two device bodies is improved, and the force applied by the pull wire to the device body causing the two device bodies to separate is avoided, thereby increasing safety during work.

[0017] Furthermore, there are two brake racks, and the two brake racks are arranged in a mirror image.

[0018] By adopting the above technical solution, two brake frames and two friction wheels are set to increase the contact area between the brake frames, friction wheels and the pull wire. As the contact area increases, the friction force between the brake frames, friction wheels and the pull wire increases, and then when the friction wheels are no longer driven, the pull wire can be effectively limited by the friction force between the three to prevent the pull wire from loosening.

[0019] Furthermore, four top wheels are provided, and the four top wheels are staggeredly distributed.

[0020] By adopting the above technical solution, after the friction wheel rotates, the pull wire is transported by friction force and the pull wire is straightened. At the same time, the friction between the two friction wheels and the pull wire causes the two friction wheels to move toward each other, and the friction wheel drives the top wheel to rotate to push the brake frame open, thereby preventing the brake frame from contacting the pull wire and affecting the pull wire transportation.

[0021] In summary, the present invention mainly has the following beneficial effects:

[0022] The present invention is provided with a friction wheel, a top wheel, a spring, a brake frame, a gear, a limit bar and a limit rod. After the friction wheel rotates, the friction force is used to transport the pull wire and thus straighten the pull wire. At the same time, the friction wheel drives the top wheel to rotate to push the brake frame open, so as to avoid contact between the brake frame and the pull wire affecting the pull wire transportation. When the friction wheel is no longer driven, the brake frame is affected by the spring and fits the pull wire. At the same time, the gears are used to make the two brake frames move synchronously to hold the pull wire. When the friction wheel drives the top wheel to reverse, the top wheel will abut against the brake frame and thus brake and limit the friction wheel. At this time, the pull wire is limited by the friction force between the brake frame, the friction wheel and the pull wire. There is no need to apply force to the pull wire by the motor or the staff manually. The structure is simple, the operation is convenient and labor-saving, so as to facilitate the installation of the auxiliary pull wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] An auxiliary device for erecting a wire for an electric pole, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, it includes a device body 1, and two symmetrically distributed friction wheels 2 are connected inside the device body 1, which convey the pull wire 10 by friction force, and later limit the pull wire 10 by friction force, and four top wheels 3 are respectively sleeved on the outside of the two friction wheels 2, and the four top wheels 3 are respectively in contact with two brake frames 6, and the friction wheel 2 drives the top wheel 3 to rotate to push the brake frame 6 open to prevent the brake frame 6 from contacting the pull wire 10 and affecting the feeding of the pull wire 10, and later limit the friction wheel 2 to prevent the friction wheel 2 from reversing, and cooperate with the limited friction wheel 2 to limit the pull wire 10 by friction force, the four top wheels 3 are staggered to avoid conflict between the four top wheels 3 and affect the operation of the structure, two springs 5 ​​are respectively connected to the upper and lower parts of the device body 1, and the two brake frames 6 are respectively affected by the two springs 5 ​​to fit with the pull wire 10, and the pull wire 10 is limited by the friction between the brake frame 6 and the pull wire 10, and one end of the two springs 5 ​​is connected to the two brake frames 6, and the two brake frames 6 are both connected to the device The main body 1 is rotatably connected, and the two brake frames 6 are mirror-set along the center line of the horizontal axis of the device main body 1. Four gears 7 are respectively sleeved on the outside of the two brake frames 6. When the friction wheel 2 is no longer driven, the brake frame 6 is affected by the spring 5 and fits with the pull wire 10. At the same time, the gear 7 makes the two brake frames 6 move synchronously to hold the pull wire 10. At this time, the pull wire 10 is limited by the friction between the brake frame 6 and the pull wire 10, and there is no need to apply force to the pull wire 10 by the motor or the staff. Four limit bars 8 are connected to the left side of the two brake frames 6. The four limit bars 8 are staggered to avoid conflict between the four limit bars 8 and affect the operation of the structure. Four limit rods 9 are respectively connected to the left side of the inside of the device main body 1. The limit bars 8 are in contact with the limit rods 9. The brake frame 6 is limited by the cooperation of the limit bars 8 and the limit rods 9 to avoid the brake frame 6 rotating outside the device main body 1, which will cause the gears 7 to be unable to align when the device is spliced ​​next time. The structure is simple, easy to operate and labor-saving, so as to facilitate the installation of the auxiliary pull wire 10.

[0033] See Figure 1 and Figure 2 In the above embodiment, one end of the friction wheel 2 is connected to the keyway shaft 4. The staff connects the keyway shaft 4 to the motor through a coupling or directly sleeves a hand-cranked tool on the keyway shaft. The brake frame 6 is connected to the pull wire 10. The brake frame 6 abuts against the pull wire 10. The pull wire 10 is limited by the friction force between the brake frame 6 and the pull wire 10. There are two device main bodies 1. A fastening bolt 11 is connected between the two device main bodies 1. Multiple fastening bolts 11 are symmetrically distributed on the outer surface and back of the device main body 1. The fastening bolts 11 are rotatably connected to the device main body 1 located below, and the fastening bolts 11 abut against the device main body 1 located above, so that the upper device main body 1 and the lower device main body 1 are fitted and limited by the fastening bolts 11, which makes it convenient for the staff to erect the pole pull wire 10.

[0034] The working principle of this embodiment is as follows: first, the staff fixes the lower device body 1 to the ground through the ground nails, and at the same time, the pull wire 10 is located in the device body 1 and fits with the brake frame 6 and the friction wheel 2. Then, the staff fits the upper device body 1 with the lower device body 1 and fixes them with the fastening bolts 11. At this time, the staff connects the keyway shaft 4 to the motor through the coupling or directly puts a hand tool on the keyway shaft. Then, the staff can drive the friction wheel 2 to rotate by the motor or hand tool.

[0035] After being tightened, the friction wheel 2 rotates and conveys the pull wire 10 through friction force, thereby straightening the pull wire 10. At the same time, the friction force between the two friction wheels 2 and the pull wire 10 causes the two friction wheels 2 to move toward each other, and the friction wheel 2 drives the top wheel 3 to rotate to push the brake frame 6 open, so as to prevent the brake frame 6 from contacting the pull wire 10 and affecting the conveying of the pull wire 10. When the friction wheel 2 is no longer driven, the brake frame 6 is affected by the spring 5 and fits with the pull wire 10. At the same time, the gear 7 makes the two brake frames 6 move synchronously to hold the pull wire 10, and when the friction wheel 2 drives the top wheel 3 to reverse, the top wheel 3 will abut against the brake frame 6 and thus brake the friction wheel 2 to limit the position. At this time, the pull wire 10 is limited by the friction force between the brake frame 6, the friction wheel 2 and the pull wire 10, and there is no need for the motor or the staff to manually apply force to the pull wire 10 all the time.

[0036] Disassembly: After the tension wire 10 is installed, the staff loosens the fastening bolts 11 to separate the two device bodies 1. Then the staff pulls out the ground nails to remove the lower device body 1. At this time, the brake frame 6 is limited by the limit bar 8 and the limit rod 9 to prevent the brake frame 6 from rotating outside the device body 1, which will cause the gear 7 to be unable to align when the device is spliced ​​next time.
