Description
Technical field
The utility model relates to a kind of device assembling earthed switch switching-in spring.
Background technology
At present, national grid, industrial and mining enterprises buying KYN28 type 10kV switch cubicle enormous amount, most of switch cubicle is safety when ensureing maintenance, and need switch cubicle to be furnished with JN15 type earthed switch, therefore the purchase quantity of earthed switch also increases gradually.The power core of earthed switch is switching-in spring, therefore in earthed switch assembling process, assemble switching-in spring operation seem very important, but the mode of the earthed switch of tradition assembling at present switching-in spring wastes time and energy, and instrument is not full-time sometimes, more cannot assemble, change switching-in spring.
Summary of the invention
For solving the problem, the utility model provides a kind of novel assembly tool, its technical scheme taked is: comprise swivel nut, supporting plate, screw rod and handle, supporting plate is the frame-like structure of hollow, the bottom plate face of supporting plate is fixed with swivel nut, the upper end of supporting plate is the button claw-like turned up, screw rod passes swivel nut and is threaded with swivel nut, the upper end of screw rod is multidiameter, the top of multidiameter is provided with hold-down screw, the axial plane of multidiameter is socketed with thrust ball bearing and locating piece, locating piece is positioned at the top of thrust ball bearing, and leave free gap between them, locating piece has half-arc groove from the top down, hold-down screw is located in half-arc groove, and do not contact with locating piece, the lower end of screw rod is fixed with nut, handle is horizontal through nut and interfix.
The utility model supporting plate is as the support frame of whole frock, upper end is welded with swivel nut, lower end profile is button pawl, screw thread is had in welding swivel nut, with screw rod with the use of playing guide effect, direction of feed and the speed of screw rod can be ensured, button pawl directly buckles into earthed switch spring upper bracket, early stage is without stressed effect, can directly buckle into by manpower, until when instrument starts to extrude earthed switch switching-in spring, the two applies a pair mutual tightening force each other and relative position is constant, instrument can rotate around the two binding site, plays the effect of stabilizing tool center of gravity, screw rod with weld swivel nut and utilize leading screw principle reciprocating movement in supporting plate, screw front end is multidiameter, axle head is equipped with thrust ball bearing successively, locating piece and hold-down screw, three is matched in clearance, all can be freely movable, three is assemblied on screw front end multidiameter successively, free gap is left after assembling between bearing and locating piece, hold-down screw is fixed on screw rod multidiameter terminal, directly do not contact with locating piece, only play barrier effect, and can not to thrust ball bearing, locating piece has interaction force, handle is leading screw, play the effect of carry-over moment, rotational lead screw, locating piece applies pressure to earthed switch combined floodgate spring, spring shortening is deformed into appropriate location, bearing pin is installed, complete the installation of combined floodgate spring.According to the strength size adjustment arm of force handle of combined floodgate spring, can ensure that whole assembling process force is moderate; Nut connecting handle, screw part are another centrostigma of moment of torsion, and profile is simple, are convenient to processing and change with damage.
Therefore to have cost low for the utility model, and overall structure is simple, easy to operate, structural strength is high, is easy to the features such as popularization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in the figure, this instrument comprises swivel nut 1, supporting plate 2, screw rod 3 and handle 6, supporting plate 2 is the frame-like structure of hollow, the bottom plate face of supporting plate 2 is fixed with swivel nut 1, the upper end of supporting plate 2 is the button claw-like turned up, screw rod 3 passes swivel nut 1 and is threaded with swivel nut 1, the upper end of screw rod 3 is multidiameter, the top of multidiameter is provided with hold-down screw 12, the axial plane of multidiameter is socketed with thrust ball bearing 4 and locating piece 5, locating piece 5 is positioned at the top of thrust ball bearing 4, and leave free gap between them, thrust ball bearing 4 can ensure that before locating piece 5 contacts with axis pin of the spring locating piece is freely movable, reduce the frictional force of the rear locating piece 5 of contact and screw rod 3 multidiameter contact position simultaneously, locating piece 5 has half-arc groove from the top down, hold-down screw 12 is located in half-arc groove, and do not contact with locating piece 5, the lower end of screw rod 3 is fixed with nut 7, handle 6 is horizontal through nut 7 and interfix.
When screw rod 3 light rotates, screw rod 3 and thrust ball bearing 4 interact, now locating piece can not rotate with the rotation of screw rod 3, therefore when screw rod 3 moves linearly, locating piece 5 moves linearly with screw rod 3 and can not freely rotate, until close to earthed switch bearing pin time, external force adjustment locating piece 5 accurately contacts with bearing pin again, locating piece 5 profile is designed to semicircular arc-shaped, with earthed switch combined floodgate spring bearing pin form fit, the convenient contact with combined floodgate spring bearing pin is with fixing, and being convenient to the conduction of moment, is the direct point of application of assembling switching-in spring; Turning handle 6, locating piece 5 pairs of earthed switch combined floodgate springs apply pressure, spring shortening is deformed into appropriate location, then whole instrument is turned clockwise on earthed switch locating support, rotary handle 6 slowly reconciles the decrement of spring until bearing pin overlaps with locating hole on ground switch bracket, put on pin, assembling completes, dismounting earthed switch combined floodgate spring side reverse operating.According to the strength sizing grip 6 of combined floodgate spring, can ensure that whole assembling process force is moderate.
