Abstract
Description
Technical Field
[0001] The invention relates to the technical field of power grid construction, and in particular to a safety conductor support device. Background Art
[0002] With the development and construction of power grids, it is usually necessary to replace some old wires on utility poles with some better and safer wires to ensure the smooth transportation of electricity. The existing method of replacing wires on utility poles is usually that workers or climbing robots directly carry wires to climb up the utility poles and place the wires on insulators to replace the wires. When the workers move upward with the wires, due to the heavy weight of the wires, the weight of the workers will also become heavier, which seriously affects the climbing efficiency of the workers. After climbing up the utility poles, the wires need to be bypassed by the brackets on the utility poles and placed on the insulators. The workers are not supported enough at high places, which will cause a burden on the workers when working and increase the probability of injury to the workers. When using a climbing robot, if there is rain, frost, etc. on the surface of the utility pole, the friction between the climbing robot and the utility pole will be reduced, causing the climbing robot to slip. Even if the climbing robot successfully drives the wire to the top of the utility pole, it is still necessary to accurately control the climbing robot to bypass the brackets on the utility poles and place the wires on the insulators. This process is greatly affected by wind force and is also difficult to operate. In view of the problems existing in the prior art, a safe wire support device is proposed. Summary of the invention

[0020] When replacing existing old wires with new ones, workers or climbing robots usually carry the wires directly to climb up the poles, and place the wires on the insulators to replace the wires. When the workers move upward with the wires, due to the heavy weight of the wires, the weight of the workers will also become heavier, seriously affecting the workers' climbing efficiency. After climbing up the poles, the workers need to wrap the wires around the brackets on the poles and place them on the insulators. The workers do not have enough support at high altitudes, which will burden them while they are working and increase the probability of injury to them. When using a climbing robot, if there is rain, frost, etc. on the surface of the poles, the friction between the climbing robot and the poles will be reduced, causing the climbing robot to slip. Even if the climbing robot successfully drives the wires to the top of the poles, it is still necessary to accurately control the climbing robot to wrap the wires around the brackets on the poles and place the wires on the insulators. This process is greatly affected by wind and is also difficult to operate.

[0023] Reference Figure 4 , Figure 6 and Figure 7 As shown, the rotating mechanism includes a fixed shell 3, which is fixedly connected to the middle part of the outer side of the first arc-shaped block 1. The interior of the fixed shell 3 is rotatably connected with a second rotating shaft 31 and a transmission shaft 32. The second rotating shaft 31 is located at the center of the fixed shell 3. The second rotating shaft 31 and the transmission shaft 32 are both fixedly connected with gears. The gear on the second rotating shaft 31 is meshed with the gear on the transmission shaft 32. The fixed shell 3 is rotatably connected with an inner gear ring 33 meshed with the gear on the transmission shaft 32. When the transmission shaft 32 rotates, the inner gear ring 33 is driven to rotate by the gear. The inner gear ring 33 is fixedly connected to the second fixed frame 15. The second rotating shaft 31 is fixedly connected with a second folding handle 34. A limiting mechanism for limiting the rotation of the inner gear ring 33 is provided on the fixed shell 3.
[0024] Reference Figure 6-Figure 8As shown, the limiting mechanism includes a first fixed block 4, the first fixed block 4 is fixedly connected to the fixed shell 3, a sliding block 41 is slidably connected inside the first fixed block 4, a rotating pin 42 is threadedly connected to the first fixed block 4, the rotating pin 42 is limitedly slidably connected to the sliding block 41, a spring 43 is fixedly connected between the first fixed block 4 and the sliding block 41, the spring 43 is used to drive the sliding block 41 to move toward the inner gear ring 33, the outer ring of the inner gear ring 33 is provided with circumferentially distributed grooves, the sliding block 41 is provided with a triangular protrusion that is limitedly matched with the groove adjacent to the inner gear ring 33, and the sliding block 41 causes the inner gear ring 33 to rotate unidirectionally through the triangular protrusion thereon.
[0025] Reference Figure 3 and Figure 7 As shown, a second rotating rod 5 is fixedly connected to the front side of the first arc block 1, and the second rotating rod 5 is slidably connected to two second limit frames 51 symmetrically distributed on the left and right. The first arc block 1 and the second arc block 11 are both fixedly connected to two first limit blocks 52 symmetrically distributed on the left and right. The second limit frame 51 is limitedly matched with the adjacent first limit block 52. When in use, the first arc block 1 is fixed by clamping the second limit frame 51 on the adjacent first limit block 52 on the second arc block 11.
[0026] In the process of installing the conductor using the present device, the staff first merges the first arc block 1 and the second arc block 11, wraps the electric pole with the first arc block 1 and the second arc block 11, and then inserts the first fixing pin 12 between the first arc block 1 and the second arc block 11, and rotates the first fixing pin 12 to fix the first arc block 1 and the second arc block 11 with the first fixing pin 12. After fixing the first arc block 1 and the second arc block 11, repeat the above process to fix the third arc block 2 and the fourth arc block 21 on the outside of the electric pole, and then the staff fixes the conductor on the lower side of the first fixing frame 14 and the second fixing frame 15.
[0027] After the above work is completed, the staff will tie the safety rope 29 to their body and move upward along the electric pole through the tool. The staff will drive the third arc block 2 and the fourth arc block 21 through the safety rope 29. The third arc block 2 and the fourth arc block 21 will move upward along the electric pole through the first rotating shaft 210 thereon. The third arc block 2 and the fourth arc block 21 will drive the first limit frame 23 and the fixed rod 24 to move upward. When the person pulls the third arc block 2 to move upward, the first folding handle 27 rotates due to the gravity of the parts below and releases the wire rope 28 on the rotating member 26. When the staff climbs to the upper end of the electric pole, they pull the two first limit frames 23, and then rotate the two first limit frames 23 to rotate the first limit frames 23 to contact the top of the electric pole, and then pull out the fixed rod 24 on the left first limit frame 23, and clamp the right side of the fixed rod 24 to the first limit frame 23 on the right, and fix the two first limit frames 23 to the upper side of the electric pole through the fixed rod 24.
[0028] After the first limit frame 23 is fixed, the safety rope 29 is used to prevent the staff from falling and getting injured. Then the staff opens the first folding handle 27 and rotates the first folding handle 27. The first folding handle 27 drives the rotating member 26 to rotate. During the rotation of the rotating member 26, the wire rope 28 is reeled in. The wire rope 28 drives the first arc block 1 and the parts under it to rise, and the wires fixed on the lower sides of the first fixed frame 14 and the second fixed frame 15 rise. At this time, the weight of the wires is transferred to the first limit frame 23, and the staff no longer needs to overcome the weight of the wires to climb, thereby improving the safety at work. The first arc block 1 The second arc block 11 rotates and rises through the first rotating shaft 210 thereon. During the rising process, the protrusion on the upper side of the first arc block 1 gradually contacts the protrusion on the third arc block 2, and is aligned with the third arc block 2 under the limit of the protrusion on the third arc block 2. The first arc block 1 is located on the lower side of the third arc block 2. When the first arc block 1 no longer moves, the staff moves the two second limit frames 51 upwards, and clamps the second limit frames 51 to the adjacent first limit block 52 on the third arc block 2. The first arc block 1 and the third arc block 2 are connected together through the two second limit frames 51 to fix the first arc block 1.
[0029] After fixing the first arc block 1, the staff unfolds the second folding handle 34, and then rotates the second folding handle 34 clockwise from front to back, the second folding handle 34 drives the second rotating shaft 31 to rotate clockwise, the second rotating shaft 31 drives the transmission shaft 32 to rotate counterclockwise through the gear, the transmission shaft 32 drives the inner gear ring 33 to rotate counterclockwise, the inner gear ring 33 drives the second fixed frame 15 to rotate counterclockwise, the second fixed frame 15 drives the wire to gradually rise, so that the wire bypasses the bracket on the pole and bypasses the insulator thereon, which is convenient for the staff to lay the wire and saves the staff from the trouble of bypassing the wire around the insulator.
[0030] During the counterclockwise rotation of the second fixed frame 15, the second fixed frame 15 drives the arc rod 16 to move, and the arc rod 16 drives the first fixed frame 14 to move. The first fixed frame 14 rotates under the guidance of the first rotating rod 13. The first fixed frame 14 and the second fixed frame 15 carry the wire to bypass the insulator and face the upper right. When rotating, the arc rod 16 rotates under the action of gravity, and the arc opening of the arc rod 16 gradually faces upward to avoid the bracket on the pole. The number of teeth on the gear on the second rotating shaft 31 is smaller than the number of teeth on the inner gear ring 33 to reduce the force applied by the staff when turning the second folding handle 34.
[0031] During the counterclockwise rotation of the inner gear ring 33, the sliding block 41 contacts the inner gear ring 33. When the sliding block 41 passes through the groove on the inner gear ring 33, the groove on the inner gear ring 33 squeezes the protrusion on the sliding block 41 and drives the sliding block 41 to move toward the first fixed block 4. The spring 43 is squeezed. When the staff no longer rotates the second folding handle 34, since the first fixed frame 14 and the second fixed frame 15 are facing the upper right, the second fixed frame 15 tends to rotate downward and drives the inner gear ring 33 to rotate clockwise. When the inner gear ring 33 rotates clockwise, the protrusion on the sliding block 41 enters the groove of the inner gear ring 33 to limit the inner gear ring 33. At this time, the staff removes the wire from the first fixed frame 14 and the second fixed frame 15, and then ties the wire to the insulator to complete the installation of the wire.
[0032] After the wire is installed, the staff rotates the rotating pin 42, and the rotating pin 42 drives the sliding block 41 to move outward, so that the sliding block 41 is no longer in contact with the inner gear ring 33, and then the second fixing frame 15 rotates downward under the action of gravity, and drives the inner gear ring 33 to rotate counterclockwise, and the second fixing frame 15 drives the first fixing frame 14 through the arc rod 16, and then the second fixing frame 15 and the first fixing frame 14 are reset, and then the rotating pin 42 is rotated in the opposite direction to move the rotating pin 42 to the initial position.
[0033] After the above actions are completed, the staff removes the two second limit frames 51 from the adjacent first limit blocks 52 on the third arc block 2, and places the second limit frames 51 on the adjacent first limit blocks 52 on the first arc block 1, and then rotates the first folding handle 27 in the opposite direction to release the wire rope 28, thereby releasing the third arc block 2 and the parts thereon, so that the third arc block 2 and the parts thereon slide downward, and finally resets the first limit frame 23 and the fixing rod 24, and the staff drives the third arc block 2, the fourth arc block 21, the first limit frame 23 and the fixing rod 24 to move downward to complete the installation of the wire.
[0034] During the process of replacing the conductor, if aluminum tape or self-adhesive insulating tape is to be wrapped between the insulator and the conductor, the conductor needs to be lifted to leave enough spacing between the insulator and the conductor for operation. Currently, the workers carry the conductor on their shoulders. The load on their shoulders is heavy, and if they are not careful, there is a risk of falling from the pole, which poses a great safety hazard in construction.
[0035] Example 2: Based on Example 1, refer to Figure 10-13As shown, it also includes a fixing mechanism, which is used to fix the wire. The fixing mechanism is arranged on the first fixing frame 14 and the second fixing frame 15. The fixing mechanism includes two second fixing blocks 6 that are symmetrically distributed front and back. The two second fixing blocks 6 that are symmetrically distributed front and back are respectively fixed to the first fixing frame 14 and the second fixing frame 15. The second fixing block 6 is rotatably connected to a transmission shaft 61, and the transmission shaft 61 is used to drive the cable to rotate. The second fixing block 6 is slidably connected to a clamping frame 62, and the clamping frame 62 is rotatably connected to an elastic shaft 63. The elastic shaft 6 3 is used to squeeze the cable and prevent the cable from sliding. The transmission shaft 61 is fixedly connected with a third folding handle 64. The second fixed block 6 is provided with a clamping assembly for limiting the movement of the adjacent clamping frame 62. The second fixed block 6 is slidably connected with an elastic limit block 7. The elastic limit block 7 is initially squeezed by the adjacent transmission shaft 61. The elastic limit block 7 is in a compressed deformation state. The cross section of the elastic limit block 7 is a triangle. The elastic limit block 7 is frictionally matched with the adjacent transmission shaft 61. The elastic limit block 7 prevents the wire from detaching by friction.
[0036] Reference Fig.11 and Fig.12 As shown, the clamping assembly includes a second limit block 71, which is slidably connected to the second fixed block 6, a tension spring 72 is fixed between the second limit block 71 and the adjacent second fixed block 6, and the second limit block 71 is limitedly matched with the adjacent clamping frame 62, and the second limit block 71 is used to limit the movement of the clamping frame 62.
[0037] When fixing the cable, the staff moves the second limit block 71 outward, the tension spring 72 is stretched, and the clamping frame 62 is unlocked. After unlocking the clamping frame 62, the staff will pull the clamping frame 62 outward to separate the clamping frame 62 from the second fixing block 6, and then place the wire between the elastic shaft 63 and the adjacent transmission shaft 61, and reset the clamping frame 62. At the same time, the second limit block 71 is reset under the action of the tension spring 72, and the wire is fixed by the two transmission shafts 61 and the two elastic shafts 63. At this time, the wire is in a relaxed state.
[0038] When the two second fixing blocks 6 move to above the insulator, the wire is located above the insulator, and then the staff turns the two third folding handles 64, and the third folding handles 64 drive the adjacent transmission shaft 61 to rotate. During the rotation process, the transmission shaft 61 drives the wire to move by friction until the wire is tightened, and while the transmission shaft 61 rotates, the adjacent elastic limit blocks 7 are pulled outward to release the lock on the adjacent transmission shaft 61, preventing the elastic limit blocks 7 from affecting the rotation of the adjacent transmission shaft 61. At this time, the elastic limit blocks 7 are deformed and reset, and the wire is pulled After tightening, press the elastic limit block 7 inwards, the elastic limit block 7 contacts the adjacent transmission shaft 61, and the elastic limit block 7 is deformed. The wire no longer moves under the squeezing of the transmission shaft 61 and the elastic limit block 7. The middle parts of the two second fixed blocks 6 just correspond to the insulator. At this time, a layer of insulation is wrapped around the outer layer of the wire between the two second fixed blocks 6 to prevent cable wear. At this time, the second fixed block 6 tightens the wire, which is convenient for the staff to wind. After completing the winding of the insulation skin on the outer surface of the wire, the staff ties the wire to the insulator to complete the installation of the wire.
