Abstract
The invention discloses a disconnecting switch contact finger replacement tool and aims at designing a disconnecting switch contact finger replacement tool which is simple in structure and convenient to use. The disconnecting switch contact finger replacement tool adopts the technical scheme that the disconnecting switch contact finger replacement tool comprises an operating handle, an upright and a grip, wherein a clamping ring is arranged at the end part of the grip; the upright is fixed at the upper part of the clamping ring, and articulated with the operating handle by a pin shaft; and a hook is arranged at the end part of the operating handle, and made of a high-strength steel wire. When the tool is used, only a person operates on a frame; the tool is simple and quick; safety guarantee is provided for replacement work of GW5 series contact fingers and springs; the power-off time is shortened; and benefits are increased for an enterprise and the society.
Description
Technical field:
The present invention relates to electric construction tool, particularly a kind of isolating switch fingertip changes instrument.
Background technology:
If the fingertip of traditional GW5 Series Switch-disconnector and spring need to change, its existing method needs whole contact to remove, again contact rain cover two set bolts are pulled down, again fingertip location-plate four set bolts are pulled down after taking down rain cover, so just can change; But because set bolt is all irony, motionlessly for a long time all can there is serious corrosion, sometimes only pull down fingertip and just need two to three hours, fingertip location-plate is utilized to do fulcrum when installing again, pry open spring with stressing on both hands fingertip one end, then fingertip holder is injected in the middle of the fingertip pried open, sometimes need repeated multiple timesly just to complete, installation procedure is wasted time and energy, and brings great inconvenience to the maintenance of isolating switch.
Summary of the invention:
The object of the invention is to design a kind of structure simple, isolating switch fingertip easy to use changes instrument.
Technical scheme of the present invention is, a kind of isolating switch fingertip changes instrument, it comprises operating grip, pillar, handle, is characterized in that: be provided with shell ring in the end of handle, is fixed with pillar on shell ring top, pillar by bearing pin and operating grip hinged, be provided with hook in the end of operating grip.Described hook high-tensile steel wires are made.
The present invention utilizes lever principle and the mode that combines of fishing thinking, simplifies the operation that GW5 Series Switch-disconnector fingertip and spring are changed, easy to use, save repair time and manpower.Only two of a rain cover set bolt need be pulled down during dismounting, with small-sized bolt clipper, spring tip be cut off rear just replaceable mounting spring.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention, and Fig. 2 is using state figure of the present invention.
Embodiment:
Describe embodiment in detail by reference to the accompanying drawings, a kind of isolating switch fingertip changes instrument, and it comprises operating grip 3, pillar 6, handle 4, is provided with shell ring 5 in the end of handle, be fixed with pillar on shell ring top, pillar is hinged by bearing pin 2 and operating grip, is provided with hook 1 in the end of operating grip; Hook high-tensile steel wires described in the present embodiment are made.
The present invention in use, only two of a rain cover set bolt need be pulled down, first with small-sized bolt clipper, spring tip is cut off, hook is lived the termination of spring 8 by oral hook by fingertip spring, again shell ring is stuck on fingertip 7, buttresses handle, then press operating grip, just the spring of spring from fingertip can be gone out by hook in mouth, be loaded on limited post and can complete installation.One man operation completes, convenient to use.
The present invention only need singlely architecturally operate in use, simple and quick, provides safety assurance, shortens interruption duration for GW5 series fingertip and spring more change jobs, and creates benefit for enterprise and society increase.
