Description
Technical Field
The invention relates to the technical field of electric power, in particular to a multipurpose wire lifting tool for uninterrupted operation of a 10kV distribution network.
Background
Along with the continuous development of domestic social economy, the importance of the power industry is widely regarded, and people also put forward higher requirements on power supply quality and power supply reliability, so that distribution network uninterrupted power operation is increasingly becoming the main mode of distribution network maintenance, smooth and safe development of distribution network uninterrupted power operation is guaranteed for qualified safety tools, when three-phase wires need to be lifted in 10kV distribution network uninterrupted power operation, a lifting method of a small crane of an insulating bucket arm vehicle is usually adopted at present, and when an electric pole does not need to be dismantled, a method of installing a temporary insulating cross arm on the electric pole can be used for lifting the wires.
When the insulated cross arm is adopted to lift the wires, the existing insulated cross arm is heavy and tedious to install, so that the workload of operators is heavy, the physical strength consumption is huge, the height of the cross arm cannot be freely adjusted by the insulated cross arm, the wires are difficult to fix with the cross arm after the wires are shielded, the operators generally adopt an insulated rope for fixing, and the fixing mode has large workload and unstable fixation; when the insulating bucket arm vehicle is used for lifting the wires in a small hanging mode, the wires cannot keep enough phase distance due to the fact that the three-phase wires need to be lifted at the same time, and the risk of phase-to-phase short circuit exists.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a 10kV distribution network uninterrupted power operation multipurpose wire lifting tool, which is characterized in that: the top of insulating frame (3) is provided with rings (1), be provided with fixed orifices (2) on insulating frame (3), insulating frame (3) are fixed on insulating support (4), insulating prop (6) are fixed in the bottom of insulating support (4) through the bolt, be provided with adjusting stud (7) on insulating prop (6), the lower tip of adjusting stud (7) is connected with lifting hook rings (9) through lock nut (8), be provided with adjusting stud (7) on lifting hook rings (9), the lower tip of adjusting stud (7) is connected with lifting hook locking upper ring (10) through lock nut (8).
An adjusting ring (5) is arranged on the upper part of the adjusting stud (7).
The inner diameter of the upper part of the locking nut (8) is smaller than that of the lower part of the locking nut, a clamping block is arranged at the bottom of the adjusting stud (7), the adjusting stud (7) penetrates through the locking nut (8) and clamps the clamping block in the locking nut (8), and the diameter of the clamping block is larger than that of the adjusting stud (7).
The invention has the beneficial effects that: compared with the conventional wire lifting device and method, the tool is high in operability and safety, and can ensure the phase-to-phase and ground insulation performance in the lifting process, the three-phase wires can be lifted simultaneously in the lifting process of the wires, and the proper lifting height difference can be selected by adjusting the position of the lifting hook, so that the relative positions of the three-phase wires are ensured to be unchanged, and the phase-to-phase insulation is good; the adjusting range of the lifting hook is large, the wire can be directly clamped and fixed, and the wire which is shielded by an insulating tube or an insulating blanket can also be clamped and fixed; compared with the existing method of binding by using an insulating rope sleeve, the method of directly clamping the hook has higher safety and operability, reduces the operation risk and improves the safety; the hook part uses large-span threads to realize the locking and opening functions, the operation is simple and convenient, and the locking is stable; the clamping and the up-and-down adjustment of the lead are both operated by using an insulating rod, so that the safety distance is ensured, and the safety of operating personnel is improved.
