Description
Technical Field
[0001] The invention relates to the technical field of power transmission and distribution engineering, in particular to a foldable electric ladder head device for repairing ground wires. Background Art
[0002] In overhead power transmission lines, the ground wire is exposed to the natural environment for a long time and is prone to wear, breakage and other damages. Regular repair and maintenance are required to ensure the safe and stable operation of the transmission line. The foldable electric ladder head device provides a convenient and safe way for workers to reach the damaged location of the ground wire for repair work, ensuring the normal operation of the power project and the reliability of power supply.
[0003] The traditional ladder head device used for repairing ground wires is mainly composed of a metal frame, a clamp and simple operating parts. The metal frame is mostly a rigid structure connected by welding or bolts. As the supporting skeleton of the entire ladder head, it bears the weight of the operator and tools. The clamp is generally installed at the bottom of the frame through a simple mechanical connection, and the opening and closing of the clamp is achieved by manually adjusting the screw or wrench to adapt to ground wires of different diameters, but this adjustment method is often not accurate and convenient enough. Some traditional ladder head devices may be equipped with simple handrails or standing platforms for operators to use, but these components are less integrated with the overall structure and have limited stability. In some slightly more complex designs, there may be a manual traction device to assist the ladder head to move on the ground wire, but this method of movement requires the operator to exert greater physical strength, and the operation is difficult, and it is difficult to achieve precise position control. In addition, if electric functions are involved, usually a small motor is simply installed on the ladder head, and a chain or belt drive is used to drive the clamp to open and close or to achieve short-distance movement of the ladder head. However, its power system and control system are relatively simple, and the coordination between the components is poor. From the perspective of the connection relationship between the components, the various parts are mostly fixed by mechanical connections such as bolts and nuts. This connection method is prone to loosening during long-term use, affecting the stability and safety of the ladder head. In view of the power source and braking problems of the traditional ground wire repair shaving head, the present invention proposes a foldable electric ladder head device for ground wire repair.

[0023] 4. The foldable electric ladder head device for repairing the ground wire is connected to the frame by a clamp using a connecting pipe. By adding a hidden pull rope in the connecting pipe, the brake clamp is connected to the power source of the drive wheel, so that when the braking is completed, the power source is shut down, which saves the cost of shutting down the power source and improves the overall linkage.
[0024] 5. The foldable electric ladder head device for repairing ground wires is equipped with a movable gear and a transmission sleeve on the output end of the motor. The power source of the entire ladder head can be determined according to whether the movable gear is engaged with the transmission sleeve.

[0025] 6. The foldable electric ladder head device for repairing the ground wire is located at the side end of the motor through an adjusting rod. The adjusting rod is driven like a lever, which plays a connecting role between the pulling rope and the movable gear, and achieves the most important effect on the switch of the braking control power.
[0026] 7. The foldable electric ladder head device for repairing the ground wire is equipped with an anti-detachment safety buckle at the lower end of the driving wheel on the frame.

When the movable sleeve 17 is controlled to move, it will not affect the rotation of the movable sleeve 17, and the middle position of the adjusting rod 21 is active with the positioning block 22. The other end of the adjusting rod 21 is connected to the inner wall through the second spring 23, so that the elastic force of the second spring 23 is utilized to make the movable gear 11 always engaged with the slot 20, and the entire adjusting rod 21 is driven like a lever. When this end of the adjusting rod 21 tilts toward the inner end, the end of the adjusting rod 21 located at the movable sleeve 17 moves outward, thereby driving the movable gear 11 to disengage from the transmission sleeve 10, causing the transmission sleeve 10 to idle, and the movable gear 11 loses its rotational force.
[0046] The linkage device includes a brake block 30, a movable shaft 31, a first adjustment rod 32 and a second adjustment rod 33, wherein the clamp 9 is composed of a clamping head 27 and a handle 28, a clamping groove 29 corresponding to the ground wire 2 is provided in the middle of the clamping head 27, and the lower end of the clamping head 27 corresponding to the clamping groove 29 is movably connected with the brake block 30, and the brake block 30 is arranged in a semi-arc shape, one end of the brake block 30 is fixedly connected with the movable shaft 31, and the movable shaft 31 is movably connected with the clamping head 27, and the movable shaft 31 is located at the outer end of the clamping head 27 and is obliquely fixed with the first adjustment rod 32, and the side end of the first adjustment rod 32 is movably connected with the second adjustment rod 33. There are two adjusting rods 33, and the second adjusting rod 33 is set horizontally. The clamping head 27 in the clamp 9 will have a clamping groove 29. During installation, the clamping head 27 will be clamped by the handle 28, so that the clamping groove 29 in the clamping head 27 is sleeved on the grounding wire 2, so that the clamp 9 moves when sliding. When braking is needed, the second adjusting rod 33 is adjusted to drive the first adjusting rod 32 to flip the movable shaft 31, so that the brake block 30 is rotated, so that the brake block 30 presses the grounding wire 2, and the friction between the texture on the brake block 30 and the grounding wire 2 forms a brake.
[0047] The clamping head 27 is provided with a sliding groove 34 at the position corresponding to the second adjusting rod 33, and the side end of the second adjusting rod 33 extends to be clamped with the sliding groove 34, and the clamping head 27 is provided with fixing grooves 35 at both ends corresponding to the sliding groove 34, and the second adjusting rod 33 is movably connected to the inner wall of the sliding groove 34 through a third spring 39, and a spring block 36 is provided at one end of the second adjusting rod 33.

The braking block 30 is provided in the clamping head 27. When not in use, the clamping groove 29 and the grounding wire 2 are movable without real-time clamping. When braking is required, the second adjusting rod 33 only needs to be pulled outward to complete the braking of the grounding wire 2 by the brake block 30.
[0048] The pull cord 24 passes through the connecting tube 8 and extends to the clamping head 27, and the pull cord 24 is fixedly connected to one end of the second adjusting rod 33. When the second adjusting rod 33 is pulled outward, the pull cord 24 will be pulled outward, thereby pulling the pull cord 24 to shorten the pull cord 24 inside the frame 3, thereby pulling the adjusting rod 21 closer to the inner wall.
[0049] The anti-separation safety buckle 7 is arranged in a hook shape, and one end of the anti-separation safety buckle 7 is movably connected to the side end of the frame 3, and the position of the anti-separation safety buckle 7 corresponding to the transmission wheel 4 is fixedly connected to a limiting member 37, and the limiting member 37 is arranged in an M shape and wrapped with the ground wire 2. Since the interior of the transmission wheel 4 is recessed, it is suitable for being clamped with the ground wire 2, and the recess of the transmission wheel 4 is relatively large, the limiting member 37 on the anti-separation safety buckle 7 corresponds to the recess in the transmission wheel 4, thereby preventing the ground wire 2 from deviating from the track of the transmission wheel 4.
[0050] A buckle groove 38 is provided at the center position of the outer ends of the two transmission wheels 4 , and the outer end of the anti-separation safety buckle 7 is movably engaged with the buckle groove 38 .
[0051] Working principle: when it is needed, first place the two transmission wheels 4 on the ground wire 2, and then use the anti-detachment safety buckle 7 to stably buckle the frame 2 on the ground wire 2. During the operation of the carrier, the cable is always firmly locked. After the clamp 9 clamps the ground wire 2, it generates electricity through the electric control box 6, thereby starting the motor 5, so that the motor 5 drives the transmission wheels 4 to rotate, so that the two transmission wheels 4 slide on the ground wire 2, so that the entire frame 3 moves. With the movement of the frame 3, the clamp 9 clamping the ground wire 2 also slides. When it slides to the required position, the ground wire 2 is braked by the clamp 9 to stop the movement of the frame 3.
[0052] When the clamp 9 needs to brake, the clamp head 27 will be clamped by the handle 28 during installation, so that the clamp groove 29 in the clamp head 27 is sleeved on the ground wire 2, so that the clamp 9 moves when sliding. When braking is needed, the first adjustment rod 32 is adjusted by the second adjustment rod 33 to flip the movable shaft 31, so that the brake block 30 rotates, so that the brake block 30 presses the ground wire 2, and the friction between the texture on the brake block 30 and the ground wire 2 forms a brake. The clamp head 27 is provided with a slide groove 34, which can make the second adjustment rod 33 move horizontally. After moving to the fixing groove 35, the upper end of the second adjusting rod 33 will pop out the spring block 36, so that the second adjusting rod 33 is located on the sliding groove 34 for fixing. The brake block 30 is provided in the clamping head 27. When not in use, the clamping groove 29 and the grounding wire 2 are movable without real-time clamping. When braking is required, the second adjusting rod 33 only needs to be pulled outward to complete the braking of the grounding wire 2 by the brake block 30. When the second adjusting rod 33 is pulled outward, the pulling rope 24 will be pulled outward, so that the pulling rope 24 inside the frame 3 is pulled, and the pulling rope 24 inside the frame 3 is shortened, thereby pulling the adjusting rod 21 close to the inner wall;
[0053] After the clamp 9 is braked, a transmission sleeve 10 is installed on the output end of the motor 5, and the movable gear 11 is connected to the interlocking gear 15 on one of the rotating shafts 12 through a chain 14. The movable gear 11 itself has no rotating force. When the movable gear 11 is engaged with the transmission sleeve 10, the rotation of the motor 5 will drive the movable gear 11 to rotate through the transmission sleeve 10, and the movable gear 11 will drive the interlocking gear 15 to rotate through the chain 14, thereby rotating the rotating shaft 12. A slot 20 is provided at the side end of the transmission sleeve 10, and the outer end of the slot 20 is larger than the inner end, and the width of the movable gear 11 is larger, and one side end of the movable gear 11 will be engaged with the slot 20, and the outer end of the slot 20 is larger than the inner end, which is convenient for the movable gear 11 to be inserted into the slot 20, and the other side end of the movable gear 11 will be engaged with the chain 14 is connected, the front end of the adjusting rod 21 is a U-shaped limiting sleeve 26, which will be mutually engaged with the limiting groove 25 on the movable sleeve 17. When the movable sleeve 17 is controlled to move, it will not affect the rotation of the movable sleeve 17, and the middle position of the adjusting rod 21 is active with the positioning block 22. The other end of the adjusting rod 21 is connected to the inner wall through the second spring 23, so that the elastic force of the second spring 23 is utilized to make the movable gear 11 always engaged with the slot 20, and the entire adjusting rod 21 is driven like a lever. When this end of the adjusting rod 21 tilts toward the inner end, the end of the adjusting rod 21 located at the movable sleeve 17 moves outward, thereby driving the movable gear 11 to disengage from the transmission sleeve 10, causing the transmission sleeve 10 to idle, and the movable gear 11 loses its rotational force, thereby stopping the continued movement of the frame 3.
