The plane, top, top 71 of described lock body part 7 extends upward the small lugs 73 of a clamping lock head part 1 when electric control lock is extracted half-twist also.
Operating principle of the present utility model and process are:
Electric control lock is installed on the electric fixtures of wanting locking, its position can make the lockweight head 52 of electric control lock stop the operating mechanism action of electric fixtures when electric control lock is in blocking, and when the lockweight head 52 of electric control lock is raised with locking bar 5, the operating mechanism of electric fixtures can move, and this moment, electric fixtures and electric control lock all were in released state.
1. the principle of the locking of normal running and release and the course of work
Electric control lock is to utilize the movable mandrel 81 of set solenoid 8 to stop the mobile purpose that reaches locking of the locking bar 5 on the lock body 7, its course of work is: peripheral control unit gives solenoid 8 energisings, its movable mandrel 81 is mentioned from the cannelure 54 of locking bar 5, locking bar 5 is not stopped in the axial direction, operating personnel can pull up locking bar at the tapered end end, make the lockweight head of locking bar leave interlock, reach the normal release purpose.Because rotation locking groove 58 interlocks mutually on latch 3 and the locking bar 5 make locking bar 5 can not rotate moving axially, therefore, in normal operation, tapered end 1 can not rotate.
2. the principle of emergency release and the course of work
1. as Fig. 2 b, shown in the 2c, during emergency release, open lock nut 4, socket cap 59 places that the key body 200 of emergency release key and projection 400 inserts tapered ends 1 and be inserted in locking bar 5, rotation locking groove 58 places that the projection 400 of key inserts locking bars 5; Extruding latch 3 is thrown off from the rotation locking groove 58 on the locking bar 5; Latch spring 2 is compressed simultaneously; 5 to 90 ° of rotation locking bars, at this moment, the movable mandrel 81 of the breach 51 subtend solenoids 8 on the locking bar 5, and the location abaculus 12 of tapered end 1 is stuck inactive by the groove 72 of lock body 7.
2. because the width of breach 51 greater than the width of the movable mandrel 81 of solenoid 8, can not stopped movable mandrel 81 in breach 51; With portable tapered end 1 and overcome the resistance of the spring 6 on the main paragraph 56 of locking bar 5 and the lockweight head 52 that drives locking bar 5 is extracted from the hole of the object 9 of locking, as shown in Figure 3.
When 3. another mistake hour hands screw key drive tapered end 1 changeed 90 °, tapered end 1 was blocked stop motion by the small lugs 73 of lock body 7.But key continuation drive 5 inverse times of locking bar forward 90 ° to and locate to stop, and tapered end location abaculus 12 drops on the last plane on lock body top 71.Latch 3 slides into the rotation locking groove 58 places interlock on the lock shaft 5 under spring 2 effects simultaneously, and key outside pulls out, and takes out.As shown in Figure 4.
4. after the site plant operation is finished, clockwise rotate 1 to 90 ° of tapered end with hand.Drive locking bar 5 simultaneously and fall back to original position, locking bar 5 drives tapered end 1 and moves downward in this process under the effect of spring 6, the movable mandrel 81 of the inclined-plane 53 compressing solenoids 8 on the locking bar 5 moves upward, guarantee after movable mandrel 81 slips over the highest point on inclined-plane 53, to fall into cannelure 54 places of locking bar 5 by design size, get back to normal blocking, can't pull up tapered end 1 with hand this moment.
The utility model can be widely used in power system five-defence block electronic lock, makes things convenient for fields such as equipment fault or the interim release of when maintenance.
Above-mentioned listed specific implementation is nonrestrictive, and to one skilled in the art, in not departing from the utility model scope, various improvement and the variation carried out all belong to protection domain of the present utility model.
