DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1 - Figure 6 The shown device for lifting a conductor of an electric power repair tower comprises a base 1, a lifting mechanism is arranged at the top of the base 1, the lifting mechanism comprises a lifting rod 9 fixedly mounted at the top of the base 1, a connecting rod 18 is slidably connected inside the lifting rod 9, one end of the connecting rod 18 is fixedly connected to a pressing block 16, a spring 17 is arranged at the bottom end of the pressing block 16, and an inclined block 19 is fixedly connected to the other end of the connecting rod 18. The lifting mechanism can transport the fixed conductor upward so that the conductor can be transported to the top of the repair tower, which brings convenience to the repair of the repair tower. When the lifting rod 9 is extended, the lifting rod 9 on the outside will always restrict the lifting rod 9 on the inside, and can also play the role of squeezing the pressing block 16, thereby driving the connecting rod 18 to press down, so that the inclined block 19 cancels the match with the matching hole 21, and then cancels the restriction on the clamping box 20, so that the clamping box 20 can pop out to clamp and fix the conductor.

[0016] A clamping mechanism is provided inside the top of the lifting rod 9, and the clamping mechanism includes a clamping box 20 slidably connected to the inside of the lifting rod 9, a telescopic spring 22 is fixedly connected between one end of the clamping box 20 and the inner wall of the lifting rod 9, a matching hole 21 is provided inside one end of the clamping box 20, and an upper clamp 24 and a lower clamp 23 are slidably connected inside the other end of the clamping box 20, a slide groove 25 is provided at the top of the upper clamp 24 and the bottom of the lower clamp 23, a pinion 26 is rotatably connected inside the slide groove 25, an arc tooth plate 27 is fixedly connected to the inner wall of the upper clamp 24 and the lower clamp 23, through grooves 28 are provided on both sides of the upper clamp 24 and the lower clamp 23, and a button 29 is provided inside one end of the clamping box 20, and the button 29 is located at the clamping A spur plate 30 is fixedly connected to one end of the box 20, and a return spring 31 is fixedly connected between one end of the spur plate 30 and the inner wall of the clamping box 20. After the clamping box 20 pops out, the wire will touch the button 29 and squeeze the button 29 into the inside of the clamping box 20, and the button 29 will drive the pinion 26 to rotate through the cooperation of the spur plate 30 and the pinion 26. At the same time, the upper clamp 24 and the lower clamp 23 will also be moved out through the cooperation of the arc tooth plate 27 and the pinion 26. The moved upper clamp 24 and lower clamp 23 will cooperate to form a circular ring, which will confine the wire inside the circular ring to prevent the wire from swaying due to wind force during the lifting process, thereby affecting the overall stability of the device.

[0017] Four side frames 3 are fixedly connected to the four sides of the base 1, and the interiors of the four side frames 3 are slidably connected to support rods 4. The tops of the four support rods 4 are fixedly connected to pedals 5. The support rods 4 can fix the entire device on the ground. Before use, you only need to step on the pedals 5 hard to insert the support rods 4 into the ground, thereby fixing the device on the ground and ensuring the overall stability of the device.

[0018] Four universal wheels 2 are fixedly installed at the bottom end of the base 1, which facilitate the movement of the device. A counterweight block 6 is fixedly connected to the top end of the base 1. The counterweight block 6 is located on one side of the lifting mechanism. The counterweight block 6 can counterweight one side of the device according to the height of the repair tower. After the lifting mechanism is extended to the highest point, the balance of the device can still be maintained, which further improves the stability of the device.

[0019] Two brackets 7 are fixedly connected to the top of the base 1, and a pulley 8 is rotatably connected between the two brackets 7. The two brackets 7 are located on the other side of the lifting mechanism. The pulley 8 can change the direction of wire lifting and save the load-bearing force required by the lifting mechanism when lifting the wire.

[0020] A driving motor 14 is fixedly installed on one side of the bottom end of the lifting rod 9, and a guide ring 15 is fixedly connected to the outermost top of the lifting rod 9. Before fixing the wire, the wire is passed through the guide ring 15, and the guide ring 15 can be used to limit the general direction of the wire lifting, which facilitates the fixation of the clamping mechanism. The top of the lifting rod 9 is fixedly connected to a top block 10.

[0021] A fixing mechanism is provided on one side of the top block 10, and the fixing mechanism includes two fixing plates 11 fixedly connected to one side of the top block 10, and three pairs of fixing clamps 12 are provided between the two fixing plates 11. Both sides of each pair of fixing clamps 12 are connected with two adjusting knobs 13 by threads, and the adjusting knobs 13 can adjust the distance between a pair of fixing clamps 12, so that the fixing clamps 12 can fix wires of different sizes.

[0022] The connecting rod 18 connected to one end of the pressing block 16 is located inside the bottom end of the lifting rod 9, the spring 17 is located between the pressing block 16 and the bottom end surface of the lifting rod 9, and the connecting rod 18 connected to one end of the inclined block 19 is located inside the top end of the lifting rod 9. The inclined block 19 and the matching hole 21 cooperate with each other. Through the cooperation between the inclined block 19 and the matching hole 21, when the connecting rod 18 is lowered, the restriction on the clamping box 20 can be cancelled, so that the clamping box 20 can be popped out to clamp and fix the wire to prevent the swinging wire from affecting the overall stability of the device.

[0023] The upper clamp 24 and the lower clamp 23 are both matched with the pinion 26 through the arc tooth plate 27, and the straight tooth plate 30 is set inside the upper clamp 24 and the lower clamp 23 through the through groove 28 and matched with the pinion 26. Through the action of the pinion 26, the upper clamp 24 and the lower clamp 23 can be driven to move synchronously, and only when the button 29 is squeezed, the upper clamp 24 and the lower clamp 23 will be closed, thereby reducing the error when clamping the wire and making it easier to fix the wire.

[0024] Working principle: First, the wire needs to pass through the bottom of the pulley 8 and be wound around the surface of the pulley 8, then the wire needs to pass through the guide ring 15, and finally the wire needs to be fixed in the fixing mechanism. At this time, the drive motor 14 can be started to drive the lifting mechanism to rise and transport the wire to the top of the emergency repair tower. In the process of the lifting mechanism driving the wire to rise, the innermost lifting rod 9 will be extended first. When it extends to a certain height, the innermost lifting rod 9 will be restricted by the outer lifting rod 9 and squeeze the connecting rod 18 at the bottom of the innermost lifting rod 9. After the connecting rod 18 is squeezed, it will drive the inclined block 19 to descend, so that the clamping box 20 loses its restriction and pops out. The clamping box 20 that pops out will touch the wire, and the wire will squeeze the button 29. The button 29 will drive the spur plate 30 to move, and through the spur plate 3 0 cooperates with the pinion 26, which will drive the pinion 26 to rotate. The pinion 26 also cooperates with the arc tooth plate 27, thereby driving the upper clamp 24 and the lower clamp 23 to move, thereby forming a ring to restrict the wire and prevent the wire from swaying due to wind force, affecting the overall stability of the lifting device. After the wire is removed, the reset spring 31 will reset the button 29 and retract the upper clamp 24 and the lower clamp 23. When the lifting mechanism is retracted, the restriction of the lifting rod 9 lost by the connecting rod 18 will be reset under the action of the spring 17, so that the connecting rod 18 will restrict the clamping box 20 again and retract the clamping box 20. Each section of the lifting rod 9 will restrict the lifting rod 9 inside it. The above steps are repeated during extension and retraction to restrict the wire and ensure the stability of the lifting device when lifting the wire.
