Abstract
The invention refers to a special tool for dismounting a contact finger of an isolating switch, in particular to a special device for dismounting a contact finger of isolating switch located on a high voltage substation and an outdoor high voltage power distributing line. The special tool comprises a rack, a bidirectional threaded rod located on the rack, a handle located on one end of the bidirectional threaded rod, a left fixture block and a right fixture block which are located on the bidirectional threaded rod and in threaded connection with the bidirectional threaded rod, wherein the left fixture block is provided with a left fixture slot, the right fixture block is provided with a right fixture slot, the rack between the left fixture slot and right fixture slot is provided with a fixed bracket of a contact finger installation assembly, and one end of the fixed bracket of the contact finger installation assembly is provided with a push rod. The special tool solves the problem of difficult replacement as there is no stable integrating point in the installation process of the contact finger of the isolating switch. The special tool provides a stable integrating point for the dismounting of the contact finger of the isolating switch, simplifies the installation flow and improves the working efficiency and safety coefficient.
Description
Technical field
The present invention relates to a kind of isolating switch fingertip tool specially for attaching and detaching, be specially the isolated plant that dismounting is positioned at the isolating switch fingertip on high voltage substation and the outdoor high-voltage distribution line.
Technical background
Isolating switch is widely used on high voltage substation and the outdoor high-voltage controller switching equipment circuit, supplies circuit that voltage is being arranged, and does the usefulness of deciliter actuating when non-loaded.Because disconnecting link contact, fingertip all directly contact with outside air; Cause aging, the corrosion situation is general; Disconnecting link fingertip spring particularly, as the critical piece that contact force is provided for disconnecting link contact fingertip, its corrosion, damaged condition are more general; Consequence is also more serious, often need change processing to fingertip, spring.Because it is loosely organized, spring tension does not have stable meeting point greatly and in the installation process, caused no small difficulty for more changing jobs of staff.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly in isolating switch fingertip disassembly process, stable meeting point can be provided, and simplifies installation procedure, the isolating switch fingertip installation special tool with coefficient of safety of can increasing work efficiency.
The present invention adopts following technical scheme:
The present invention it is characterized in that it comprise frame, be arranged on bidirectional helical bar on the frame, be arranged on bidirectional helical bar one end handle, be arranged on and adopt the left fixture block that is threaded and right fixture block, left fixture block to be provided with the frame that left draw-in groove, right fixture block be provided with between right draw-in groove, left draw-in groove and the right draw-in groove with the bidirectional helical bar to be provided with fingertip installation component fixed support on the bidirectional helical bar, the support bracket fastened end of fingertip installation component is provided with push rod.
Beneficial effect of the present invention is:
The invention solves in the big and installation process of, spring tension loosely organized and do not have stable meeting point because of the isolating switch fingertip; The problem that is difficult to change; The dismounting that is designed to the isolating switch fingertip of fingertip of the present invention end fixed card slot provides stable meeting point, and the design of push rod makes the installation process of isolating switch fingertip more stable, and the design of handle is convenient to the staff and is applied the power that makes the rotation of bidirectional helical bar; The present invention has simplified the installation procedure of isolating switch fingertip; Meet the work on the spot needs more, also satisfied the rules requirement, improved operating efficiency and coefficient of safety simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In the accompanying drawings, 1 bidirectional helical bar, 2 handles, 3 left draw-in grooves, 4 left fixture blocks, 5 fixed supports, 6 frames, 7 right fixture blocks, 8 right draw-in grooves, 9 push rods.
Embodiment
Be depicted as a specific embodiment of the present invention like accompanying drawing 1; The present invention includes frame 6, be arranged on bidirectional helical bar 1 on the frame 6, be arranged on bidirectional helical bar 1 one ends handle 2, be arranged on and adopt the left fixture block 4 that is threaded and right fixture block 7, left fixture block 4 to be provided with the frame 6 that left draw-in groove 3, right fixture block 7 be provided with between right draw-in groove 8, left draw-in groove 3 and the right draw-in groove 8 with bidirectional helical bar 1 to be provided with fingertip installation component fixed support 5 on the bidirectional helical bar 1, an end of fingertip installation component fixed support 5 is provided with push rod 9.
During installation isolating switch is discharged according to assembling position; The isolating switch fingertip is packed between the present invention's left side draw-in groove 3 and the right draw-in groove 8, and push rod 9 is supported on isolation switch contact supporting bracket place, and so left draw-in groove 3 provides stable meeting point with right draw-in groove 8 for the dismounting of isolating switch fingertip; Push rod 9 plays the support fixation effect; Rotary handle 2, handle 2 drive 1 rotation of bidirectional helical bars, the rotation of bidirectional helical bar 1 make with bidirectional helical bar 1 through the left fixture block 4 that is threaded and right fixture block 7 each other near; The left draw-in groove 3 that is arranged on like this on the left fixture block 4 becomes extruding with 8 pairs of switch touching finger-types of right draw-in groove on being arranged on right fixture block 7; Isolating switch fingertip afterbody is opened, again the isolating switch fingertip is aimed at installation position, reverse rotation handle 2; The extruding of left side draw-in groove 3 and 8 pairs of isolating switch fingertips of right draw-in groove is cancelled, and the isolating switch fingertip can be mounted and put in place.The handle 2 that is arranged on bidirectional helical bar 1 one ends is convenient to apply the power that makes 1 rotation of bidirectional helical bar.During dismounting isolating switch is discharged according to assembling position; The isolating switch fingertip is packed between the present invention's left side draw-in groove 3 and the right draw-in groove 8; Push rod 9 is supported on isolation switch contact supporting bracket place, and rotary handle 2 opens isolating switch fingertip afterbody, and the isolating switch fingertip can be removed.
The invention solves in the big and installation process of, spring tension loosely organized and do not have stable meeting point because of the isolating switch fingertip; The problem that is difficult to change; The dismounting that is designed to the isolating switch fingertip of fingertip of the present invention end fixed card slot provides stable meeting point, and the design of push rod makes the installation process of isolating switch fingertip more stable, and the design of handle is convenient to the staff and is applied the power that makes the rotation of bidirectional helical bar; The present invention has simplified the installation procedure of isolating switch fingertip; Meet the work on the spot needs more, also satisfied the rules requirement, improved operating efficiency and coefficient of safety simultaneously.
