Description

Technical Field

[0001] This utility model relates to the field of power line technology, and in particular to a pre-stretched fitting for power lines. Background Technology

[0002] Pre-stranded hardware refers to hardware made by wrapping pre-formed spiral strips around conductors or ground wires to bear mechanical or electrical loads. In the power industry, pre-stranded hardware not only provides reliable support and fixation, but also effectively protects power lines from mechanical damage and environmental changes through its unique structural design and excellent performance characteristics, ensuring the safe and stable operation of the lines.

[0003] In actual operation, pre-stirred fittings are always in a fixed state. In special areas such as rural towns, due to the low cost and the fact that low-profile poles are not easy to collapse, the poles are usually made very low. When large vehicles pass by, they often cannot pass because they are too high. In addition, rural power lines have poor pressure resistance, and power lines often become loose, resulting in power lines hanging and threatening the safety of pedestrians. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pre-stretched fitting for power lines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pre-stretched fitting for power lines includes a pole with two sets of fixing rings connected by bolts and threads. A sliding plate (segment 3) is fixedly connected to each of the two sets of fixing rings. A slider (slider 3) is slidably connected to each of the sliding plate (segment 3). A sliding plate (segment 1) is fixedly connected to each of the slider (segment 1). A slider (slider 2) is slidably connected to each of the slider (slider 2). A housing is fixedly connected to each of the slider (slider 2). A fixing rod is fixedly connected to the housing. A clamp is mounted on the fixing rod, and the clamp holds an electrical wire. A moving component is mounted on each of the fixing rings. The moving component includes a rack fixedly connected to each of the sliding plate (segment 3). A motor is fixedly connected to the housing. A shaft is fixedly connected to the output end of the motor. A gear is fixedly connected to the shaft, and the gear meshes with the rack. A sliding plate (segment 2) is fixedly connected to each of the sliding plate (segment 3), and slider (slider 1) is slidably connected to each of the sliding plate (slider 2).

[0007] Preferably, a lifting assembly is installed on the fixed ring. The lifting assembly includes a second pulley fixedly connected to the first slider, a hook fixedly connected to the second pulley, a first pulley rotatably connected to the rotating shaft, a lifting rope wound around the first pulley, a roller fixedly connected to the rotating shaft, one end of the lifting rope being fixedly connected to the hook, the other end of the lifting rope being fixedly connected to the roller, and the lifting rope being wound around the second pulley.

[0008] Preferably, pulley one and pulley two are made of ductile iron.

[0009] Preferably, the fixture is made of aluminum-clad steel.

[0010] Preferably, the fixing rod is a drop-proof and shock-resistant rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] First, this equipment is equipped with a lifting component. By raising and lowering the clamps, the height of the power cable can be adjusted. Multiple sets of equipment can be adjusted at the same time to place the power cable in a suitable position, thus avoiding the problem of large vehicles being unable to pass.

[0020] Reference Figures 1-5A pre-stretched fitting for power lines includes a pole 1, on which two sets of fixing rings 3 are installed, connected by bolts 4. A sliding plate 3 11 is fixedly connected to the fixing rings 3, a sliding block 3 12 is slidably connected to the sliding plate 3 11, a sliding plate 55 is fixedly connected to the sliding block 3 12, a sliding block 57 is slidably connected to the sliding plate 55, a housing 10 is fixedly connected to the sliding block 57, a fixing rod 8 is fixedly connected inside the housing 10, a clamp 7 is installed on the fixing rod 8, and a wire 9 is clamped inside the clamp 7. A moving component 5 is installed on the fixing rings 3, and the moving component 5 includes a rack 51 fixedly connected to the sliding plate 3 11. A motor 6 is fixedly connected inside the housing 10. A rotating shaft 54 ​​is fixedly connected to the output end of the motor 6. A gear 52 is rotatably connected to the rotating shaft 54. The gear 52 meshes with the rack 51. A sliding plate 2 56 is fixedly connected to the sliding plate 3 11. A slider 1 53 is slidably connected to the sliding plate 2 56. The motor 6 is a reciprocating servo motor. The motor 6 drives the gear 52 to rotate back and forth, so that the distance that the housing 10 can move is the same as the sliding groove of the sliding plate 2 55, and the distance that it can move up and down is the same as the sliding groove of the sliding plate 3 11. In this case, multiple sets of equipment are set on different poles. The multiple sets of equipment work together to pull the wire 9 in different directions so that the cable 9 will not become loose.

[0021] A lifting assembly 2 is installed on the fixed ring 3. The lifting assembly 2 includes a pulley 25 fixedly connected to the slider 1 53, a hook 24 fixedly connected to the pulley 25, a pulley 1 21 rotatably connected to the rotating shaft 54, a lifting rope 26 wound around the pulley 1 21, and a roller 27 fixedly connected to the rotating shaft 54. One end of the lifting rope 26 is fixedly connected to the hook 24, and the other end of the lifting rope 26 is fixedly connected to the roller 27 and wound around the roller 27. The middle part of the lifting rope 26 is wound around the pulley 25 and the pulley 1 24. 1. When the motor 6 drives the drum 27 to rotate, the drum 27 can allow the lifting rope to be wound around the body of the drum 27. Since the pulley 25 does not move up and down, the slider 3 12 moves upward, driving the wire 9 to move upward. When the worker needs to process and maintain the wire 9, the box 10 can be lowered to facilitate the worker's maintenance work. At the same time, the pulley 25 can slide on the slide plate 25. When the box 10 moves, the lifting rope 9 can pull the pulley 25 to slide, so that the lifting component 2 and the moving component 5 will not conflict when they work.

[0022] Pulley 1 21 and Pulley 2 25 are made of ductile iron. The strength of ductile iron is close to that of steel, and it can withstand high-intensity loads. Through spheroidizing treatment, it has high plasticity and toughness, making pulley 1 21 and pulley 2 25 less prone to breakage when subjected to impact. Ductile iron has excellent wear resistance.

[0023] The clamp 7 uses aluminum-clad steel material, which consists of an inner core steel wire and an outer aluminum layer. The inner core steel wire provides strong mechanical strength, ensuring that the clamp 7 is not easily deformed or broken under high tension, while the outer aluminum layer enhances the material's corrosion resistance and conductivity, enabling the clamp 7 to maintain good performance in harsh environments.

[0024] The fixing rod 8 uses a drop-proof and shock-resistant rod. When the control clamp 7 moves, the wire 9 will vibrate. The drop-proof and shock-resistant rod has good shock resistance and reduces the damage of vibration to the clamp 7 and the wire 9.

[0025] In this utility model, the worker installs the fixing ring 3 on the pole 1 and the wire 9 is installed in the clamp 7. When the wire 9 needs to be raised or lowered, the motor 6 is started. The motor 6 drives the rotating shaft 54 ​​to rotate, the rotating shaft 54 ​​drives the roller 27 to rotate, the roller 27 winds the lifting rope 26, the lifting rope 26 moves on the pulley 25 and the pulley 21, the lifting rope 26 drives the pulley 21 to move, the pulley 21 drives the rotating shaft 54 ​​to move, the rotating shaft 54 ​​drives the housing 10 to move, the housing 10 drives the fixing rod 8 to move, the fixing rod 8 drives the clamp 7 to move, and the clamp 7 drives the wire 9 to move. Multiple sets of equipment work simultaneously to achieve the effect of moving the wire 9 up and down.

[0026] At the same time, the rotating shaft 54 ​​drives the gear 52 to rotate, the gear 52 moves on the rack 51, the gear 52 drives the rotating shaft 54 ​​to move, the rotating shaft 54 ​​drives the housing 10 to move, the housing 10 drives the fixed rod 8 to move, the fixed rod 8 drives the clamp 7 to move, and the clamp 7 drives the wire 9 to move. This allows multiple sets of equipment to move in different directions, which can increase the pulling effect and prevent the wire 9 from becoming loose and threatening the safety of passers-by.
