Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] The purpose of this utility model is to provide a portable power line lifting tool to solve the problems existing in the prior art and improve work efficiency and safety.
[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Example 1 This embodiment provides a portable power line lifting tool for power line poles. Please refer to [link / reference]. Figure 1 The system includes a support rod 1, a transmission lever 3, an adjustment mechanism 5, and a wire lifting mechanism 6. One end of the support rod 1 is fixedly connected to the fixed frame 2. The transmission lever 3 is rotatably connected to the support rod 1 via a pivot point 4. One end of the adjustment mechanism 5 is rotatably connected to the portion of the transmission lever 3 located on one side of the pivot point 4, and the other end is connected to the support rod 1. The wire lifting mechanism 6 includes a wire lifting component 61 and a transmission component 62. The transmission component 62 is connected to the portion of the transmission lever 3 located on the other side of the pivot point 4. The wire lifting component 61 is used to lift the wire. The transmission component 62 has multiple mounting positions 63 along the direction close to the wire. The wire lifting component 61 can be connected to different mounting positions 63 to adjust the relative position of the wire lifting component 61 and the transmission component 62. The adjustment mechanism 5 can adjust its own length to drive the transmission lever 3 to rotate around the pivot point 4 relative to the support rod 1, so as to lift the wire through the transmission component 62 and the wire lifting component 61.
[0022] The mechanism 5 adjusts its length to drive the transmission lever 3 to rotate relative to the support rod 1 around the pivot point 4. Utilizing the lever principle, the transmission component 62 and the lifting component 61 lift the wire, eliminating the need for manual lifting or pulling, thus saving effort, being convenient, and improving safety. Furthermore, the transmission component 62 has multiple mounting positions 63. By connecting the lifting component 61 to different mounting positions 63, the mounting positions of the lifting component 61 and the transmission component 62 can be adjusted, thereby adjusting the relative position of the lifting component 61 and the wire for better wire lifting and improved flexibility.
[0023] The fixing frame 2 can be a support frame for the line pole, or other suitable positions that can fix the support rod 1; the support rod 1 can be connected to the fixing frame 2 by bolts or clamps.
[0024] In the optional scheme of this embodiment, more preferably, the part of the support rod 1 near the transmission lever 3 is provided with multiple rotation positions 11 along its own length direction, and the rotation fulcrum 4 can be detachably rotated to different rotation positions 11.
[0025] By setting multiple rotation positions 11, the relative positions of the support rod 1 and the transmission lever 3 can be adjusted as needed, improving flexibility. Specifically, the rotation fulcrum 4 can be set as a rotation pin, and all rotation positions 11 are set as rotation holes. The rotation pin rotates through the rotation hole and is snapped into the transmission lever 3, which is convenient for disassembly and can achieve relative rotation.
[0026] In the optional embodiment, more preferably, the support rod 1 near the fixed frame 2 is provided with multiple connection positions 12 along the length and / or width direction, and the end of the adjustment mechanism 5 away from the transmission lever 3 can be detachably connected to different connection positions 12.
[0027] The support rod 1 near the fixed frame 2 has multiple connection positions 12 along both the length and width directions. This allows the relative position of the end of the adjustment mechanism 5 away from the transmission lever 3 and the support rod 1 to be adjusted as needed, further improving the flexibility of the lifting line and facilitating torque adjustment. Specifically, each connection position 12 is a connection hole, which can be detachably connected by bolts. Relative rotation can be achieved by controlling the outer diameter of the bolt to be smaller than the inner diameter of the connection hole.
[0028] In the optional embodiment, more preferably, the adjustment mechanism 5 includes a telescopic member 51 and a connecting hook 52. One end of the telescopic member 51 is rotatably connected to the transmission lever 3, and the other end is detachably hooked to the connecting hook 52. The connecting hook 52 is detachably connected to the support rod 1. The telescopic member 51 can adjust its own length to drive the transmission lever 3 to rotate relative to the support rod 1 around the rotation fulcrum 4.
[0029] The telescopic component 51 can be configured as a conventional tensioner or a screw propeller. One end is rotatably connected to the transmission lever 3 via a pin, and the other end is hooked to the connecting hook 52 via an openable hook ring. One end of the connecting hook 52 is detachably connected to the corresponding connection position 12 via a bolt. By hooking the telescopic component 51 to the connecting hook 52, assembly and disassembly are facilitated. The length of the telescopic component 51 can be adjusted manually or electrically to drive the transmission lever 3.
[0030] In the optional embodiment, more preferably, the portion of the transmission lever 3 located on the other side of the rotation fulcrum 4 is provided with multiple transmission positions 31 along the length direction, and the transmission component 62 can be detachably connected to different transmission positions 31.
[0031] By setting multiple transmission positions 31, it is beneficial to adjust the relative position of the transmission component 62 and the transmission lever 3 as needed to meet torque and position requirements, thereby improving the flexibility of line lifting.
[0032] In the optional embodiments of this example, more preferably, the transmission component 62 is rotatably connected to the transmission lever 3.
[0033] The transmission component 62 is rotatably connected to a transmission position 31 on the transmission lever 3. The rotatable connection allows the transmission component 62 to swing, which helps to improve the flexibility of the lifting line. Specifically, each transmission position 31 on the transmission lever 3 can be set as a transmission hole. The transmission component 62 is rotatably connected to the transmission hole through a pin. The part of the pin that passes through the transmission hole can be fixed by a nut to prevent the pin from disengaging from the transmission hole.
[0034] In the optional embodiment, more preferably, the transmission member 62 is configured as a transmission ring, and the transmission ring has a plurality of hook parts 64 arranged inside along the direction close to the wire, and the lifting member 61 can be detachably hooked to different hook parts 64.
[0035] Each of the attachment parts 64 has an installation position 63. By setting multiple attachment parts 64, the lifting member 61 can be attached to the attachment parts 64 at different positions to adjust the position of the lifting member 61.
[0036] In the optional scheme of this embodiment, more preferably, the hanging part 64 is set as a hanging plate, one end of the hanging plate is fixedly connected to one side wall of the transmission ring, and there is a gap 65 between the other end of the hanging plate and the other side wall of the transmission ring. The lifting member 61 can be hung on the side of the hanging plate away from the wire, and the lifting member 61 can also be moved to connect with different hanging plates through the gap 65.
[0037] The hook parts 64 are not adjacent to each other, but have gaps, allowing the lifting member 61 to extend into them. In order to facilitate the adjustment of the connection between the lifting member 61 and the hook parts 64 at different positions, the lifting member 61 can reach the corresponding hanging plate at different positions through the gap 65, which facilitates operation and improves flexibility.
[0038] In the optional embodiments of this example, it is more preferable that the side of the mounting plate away from the wire is set as a concave surface.
[0039] The side of the mounting plate away from the wire is designed as a concave surface, which is the installation position 63. The concave surface helps to improve the connection stability and prevent the connection from falling apart.
[0040] In the optional scheme of this embodiment, more preferably, the lifting element 61 is set as a lifting hook, and one end of the lifting hook is sleeved in the transmission ring and hooked to the hanging part 64.
[0041] The lifting hook is sleeved with the transmission ring to improve connection stability and prevent disengagement; and the lifting hook can hook onto the wire to lift the wire.
[0042] As mentioned above, the portable power line lifting tool provided in this embodiment has multiple position adjustment schemes, providing sufficient flexibility and facilitating the lifting of conductors at different positions on the power line pole.
[0043] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
