Abstract

The utility model relates to an electric machine lock with isolating switch, belonging to the mechanical lock type. The electric machine lock with isolating switch comprises a close square box which is composed of a box cover and a box body. The box body is provided with a direct current electric machine and a speed reducer. The end of the output shaft of the speed reducer is fixed with a gear. The gear is provided with a pin shaft sheathed with a connecting rod. The outer end of the connecting rod is provided with a drawing pin. A sliding sleeve with a long hole in the lower side back part is installed in the box body. The sliding sleeve is provided with a lock rod which extends out of the box cover. The bottom face of the back end of the lock rod is provided with a drawing pin hole. The box body is still provided with a controlling shaft. The upper end of the controlling shaft is provided with the gear, and the lower end of the controlling shaft is provided with a cam. When electricity delivering and cutting operation is mistakenly operated, the electric machine lock with isolating switch can close the isolating switch to avoid accident occurring during the electricity delivering and cutting course.

Description

The isolating switch electromechanical locks

The utility model belongs to the mechanical lock class.

When electric substation sent electricity, the correct electric operation of sending should be to close isolating switch earlier, after close oil switch.During outage, correct operation should be to draw oil switch earlier, the post-tensioning isolating switch.If faulty operation belongs to the on-load operation, short circuit will appear, have an accident.How to solve the misoperation problem of electric substation, still do not have desirable, reliable device so far.

The purpose of this utility model is: the isolating switch electromechanical locks that provides a kind of electric substation to prevent misoperation.

The technical solution of the utility model is: the square box that adopts a sealing of being made up of lid, box body; Direct current machine, decelerator, reducer output shaft end are housed in box body are fixed with a gear, a bearing pin is arranged on the eccentric position of gear, be with a connecting rod on the bearing pin, the connecting rod outer end has one to strike out; The sliding sleeve that there is slotted hole at a downside rear portion is housed above in box body, the locking bar that stretches out lid is housed in the sliding sleeve, bottom surface, locking bar rear end has one to strike out the hole; A Control Shaft also is housed in box body, and a gear is equipped with in the upper end of Control Shaft, and a fan-shaped semicircle cam is equipped with in the lower end, and a JWL series limit switch is housed in the side of cam.

Electromechanical locks of the present utility model, when sending electricity and outage misoperation in electric substation, isolating switch is made and send electricity and outage to carry out by locking, has safety to send the good effect of electricity and outage.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the appliance wiring schematic diagram.

11 is box bodys among the figure, the 10th, and lid, lid and box body are formed the square box of sealing, not only are applicable to indoorly, more are applicable to outdoor use.Direct current machine 7 is housed in box body 11, decelerator 9, the output of decelerator 9 is fixed with a gear, bearing pin of the eccentric position of gear is set with a connecting rod 12 on the bearing pin, connecting rod 12 outer ends have one to strike out, the sliding sleeve 13 that there is slotted hole at the downside rear portion is housed above in box body, the locking bar 10 that stretches out lid 1 is housed in the sliding sleeve 13, and locking bar 10 rear end downsides have one to strike out the hole, strike out the hole and plug together with striking out mutually of connecting rod 12 outer ends.A Control Shaft 4 also is housed in box body, and a gear is equipped with in the upper end of Control Shaft, and this gear is meshed with the gear of decelerator 9 output axle heads, and the number of teeth of two gears is identical, and speed changer 9 output shafts and Control Shaft 4 are rotated synchronously.A fan-shaped semicircle cam 6 is housed in the Control Shaft lower end, and a JWL series limit switch 5 is equipped with in the side of cam 6.Electromechanical locks of the present utility model is subjected to the control of LX series travel switch 14 to produce motion.When switch 14 is started, 9 runnings of motor 7 drive speed transmission; The output shaft of speed changer 9 and gear make the cam 6 of Control Shaft 4 and lower end rotate synchronously again, and 6 on fan-shaped semicircle cam makes direct current machine 7 dead electricity stalls afterwards at the scope inner control JWL of 180 degree series limit switch 5, makes pin rod 10 be in outer end or inner end; When back-to-back starting switch 14 once more,, but still being in the state of being energized, motor 7 make cam 6 idle running half cycles, motor 7 dead electricity stalls with circuitry cuts though cam 6 rotates switch 5 and inoperative; In the half cycle process of cam 6 idle running, connecting rod 12 makes locking bar 10 be in inner end or outer end again, when so just making misoperation rotate rotating disk 3, makes pin rod 10 that rotating disk 3 is in locking states, and rotating disk can't rotate.When having only proper operation, the preceding paragraph operation sequence could be in locking bar 10 position (locking bar 10 is in the inner end) of release by switch 14.For easy to assembly, can be with motor 7, speed changer 9, Control Shaft 4, switch 5 are assemblied in earlier on the base plate 8, base plate 8 are contained in the box body 11 afterwards again.In order to adapt to outdoor application, lid 1 is that sealing is assembled with box body 11, and locking bar 10 adopts pressure cap 2 and sealing ring assembling with lid 1, and the fairlead of three leads 01,02,03 adopts rubber seal.For making locking bar 10 avoid corrosion to lose efficacy, locking bar 10 preferably adopts stainless steel material.
