Problems solved by technology

[0003] It is understood that the line needs to be lifted when replacing it. The method of lifting the wire in the prior art requires two insulated bucket trucks to work together, and one insulated arm truck The bucket arm truck lifts live wires from the top of the line with an insulated small crane, and another insulated bucket arm truck transports workers to insulators, transformers, line fittings, etc. for live work, or workers climb to the top of the pole for insulation support The rod method is used to lift the wires. The first method wastes the work cost, while the operation method of the insulating support rod is heavy, the wires are heavy, the lifting is laborious, and the automation level is low, the labor intensity is high, the efficiency is low, and the operator directly contacts the high-voltage wires , easy to cause electric shock accidents, and there is a great potential safety hazard

Embodiment 1

[0034] Such as figure 1 , 2 , 3, and 4, a wire lifting device for live work in distribution networks, including a magnetic adsorption positioning and clamping mechanism, a swing arm adjustment mechanism, and a jacking mechanism; each part is described in detail below:

[0035] The magnetic adsorption positioning and clamping mechanism includes a clamping and positioning base 15, an electromagnet 17 and a vertical beam 13. In this embodiment, the bottom of the clamping and positioning base 15 forms a U-shaped groove 4, which can be straddled on the cross arm 14 , convenient for clamping and positioning, and its opening size can be adjusted according to the cross-arm 14 on site;

[0036] The electromagnet 17 is arranged inside the clamping and positioning base 15. It is a strong magnetic force electromagnet, which can be firmly adsorbed on the cross arm 14, and contacts the cross arm 14 through a magnetic conductor 29. One side of the clamping and positioning base 15 is provide...

Embodiment 2

[0046] Such as figure 2 , 3 , 5, and 6, the lifting device for live wires in distribution networks provided by this embodiment is a further improvement on Embodiment 1, and also includes a second drive mechanism that can drive the base compared to Rotate on the beam; Specifically, the second drive mechanism includes a second drive motor 8, the second drive motor is installed below the beam, and its output end is fixedly connected to the base, the lower part of the base The tapered roller bearing 30 is in contact with the beam, and the second drive motor 8 is used to drive the jacking mechanism to rotate relative to the beam 9, and the jacking frame 21 is adjusted to lift the wire 5 at an optimal angle;

[0047] Further, it can be considered that the control module 16 is connected in communication with the second drive motor 8 and controls the operation of the second drive mechanism.

[0048] Other structures of this embodiment are the same as those of Embodiment 1, so detai...

Abstract

The invention relates to a distribution network hot-line work wire lifting device. The device comprises a magnetic adsorption positioning and clamping mechanism, a swing arm adjusting mechanism and a jacking mechanism, wherein the magnetic adsorption positioning and clamping mechanism comprises a clamping and positioning base, an electromagnet and a vertical beam, the electromagnet is arranged in the clamping and positioning base and can make contact with a cross arm through a magnetizer, and the vertical beam is movably connected with the clamping and positioning base in the vertical direction; the swing arm adjusting mechanism comprises a cross beam and a first driving mechanism, one end of the cross beam is rotatably connected with the vertical beam, the other end of the cross beam is rotatably connected with the jacking mechanism, and the first driving mechanism can drive the cross beam to rotate around the vertical beam; and the device further comprises a third driving mechanism, and the third driving mechanism is connected with the jacking mechanism and can drive the jacking mechanism to vertically move. The positions of the lifting device and a lifted wire can be conveniently adjusted, the wire is reliably lifted, and the hot-line work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of live working tools, and in particular relates to a lifting device for live working conductors in a distribution network. Background technique [0002] At present, in the live operation process of the distribution network, it is often encountered that insulators, transformers, line fittings, etc. need to be replaced due to damage and defects. [0003] It is understood that the line needs to be lifted when the replacement is performed. The method of lifting the wire in the prior art requires two insulated bucket trucks to work together. One insulated bucket truck lifts the live wire from above the line with a small insulated crane. Another insulated bucket truck transports workers to insulators, transformers, line fittings, etc. for live work, or the workers climb to the top of the pole and use the insulating support rod method to lift the wires. The first method wastes work costs, while using The operatio...
