The interlocking device is arranged between a nut and a big shaft of the earth switch and comprises an earth switch interlocking plate, a rotating plate and a rocker; one end of the earth switch interlocking plate is connected with the rocker by the rotating plate, the other end thereof is connected with a crankarm sheet of the big shaft of the earth switch on the big shaft of the earth switch, and an elongated slot is arranged on the earth switch interlocking plate; the nut is arranged on a fixed block by a bearing, a pin shaft is assembled at the lower side of the fixed block, the rotating plate is assembled on the pin shaft, a returning spring is arranged on the fixed block, and the other end of the returning spring is connected with the rotating plate; and the middle part of the rocker is provided with a boss, the end part of the rocker is provided with a pin shaft, a limit groove is arranged on the nut, and the boss is clamped in the limit groove. The interlocking device has reliable interlocking.
Description
Technical field
The utility model relates to a kind of high voltage switchgear handcart advancing mechanism, specifically a kind of propulsive mechanism earthed switch interlock.
Background technology
The ground connection of the propulsive mechanism that adopts both at home and abroad interlocking is to adopt when earthed switch closes a floodgate mostly at present, drive limiting plate and turn to the position that leading screw is spacing, the structure that leading screw can not be rotated, thereby realized that propulsive mechanism is when earthed switch closes a floodgate, can not pass in and out the function of car operation, but the spacing arm of force on leading screw has only 40 millimeters at most, and about 300 millimeters of the arm of force of operator handle, considerably beyond the spacing arm of force, so just easily position limiting structure is damaged.
The utility model content
The purpose of this utility model provides a kind of propulsive mechanism earthed switch interlock, realize interlock to solve in existing propulsive mechanism and the switch cabinet grounding switch interlocking by the mode of forcing the restriction leading screw to rotate, its parts damage easily, and insecure problem of interlocking.
The utility model is provided with interlock between screw and earthed switch macro-axis, interlock comprises earthed switch interlock plate, flap, rocking bar, earthed switch interlock plate one end links to each other with rocking bar by flap, the other end of earthed switch interlock plate links to each other with earthed switch macro-axis connecting lever sheet on the earthed switch macro-axis, and the earthed switch interlock plate is provided with elongated slot; On fixed block, the fixed block downside is equipped with pivot pin to screw by Bearing Installation, and flap is assemblied on the pivot pin, and fixed block is provided with return spring, and the other end of return spring links to each other with flap; The middle part of rocking bar is provided with boss, and the end of rocking bar is provided with pivot pin, and screw is provided with stopper slot, and boss snaps in the stopper slot.
The utility model provides closing at earthed switch of a kind of flexibility fashionable, chain between its propulsive mechanism and the switch cabinet grounding switch is not to realize interlock by the mode that mandatory restriction leading screw rotates, but the idle running by screw, can not pass in and out the car operation, interlocking is reliable.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sketch that the rocking bar in the utility model resets to horizontal level;
Fig. 3 is an A-A broken section vertical view among Fig. 1.
Embodiment
The utility model is provided with interlock between screw 5 and earthed switch macro-axis 7, interlock comprises earthed switch interlock plate 1, flap 2, rocking bar 4, earthed switch interlock plate 1 one ends link to each other with rocking bar 4 by flap 2, the other end of earthed switch interlock plate 1 links to each other with earthed switch macro-axis connecting lever sheet 71 on the earthed switch macro-axis 7, and earthed switch interlock plate 1 is provided with elongated slot 11; Screw 5 is installed on the fixed block 6 by bearing 61, can be around rotational shown in Figure 2; Fixed block 6 downsides are equipped with pivot pin 3, and flap 2 is assemblied on the pivot pin 3, and pivot pin 3 is rotating shafts of flap 2; Fixed block 6 is provided with return spring 9, and the other end of return spring 9 links to each other with flap 2; The middle part of rocking bar 4 is provided with boss 43, and the end of rocking bar 4 is provided with pivot pin 42, and rocking bar 4 is around pivot pin 42 motions, and screw 5 is provided with stopper slot 51, and boss 43 snaps in the stopper slot 51.Rocking bar 4 is provided with elongated slot 41.
Interlock plate 1 can level horizontally slip under the driving of macro-axis connecting lever 71, being slidingly connected of interlock plate 1 is to be realized by two elongated slots 11 of 1 on the interlock plate, the two ends of elongated slot 11 are two position of rest of interlock plate 1, when earthed switch close fashionable, ground connection macro-axis connecting lever sheet 71 drives interlock plate 1 and slides into position shown in Fig. 2 dotted line, interlock plate 1 drives flap 2 simultaneously and clockwise rotates dotted line position shown in Figure 2, at this moment flap 2 just in time inserts in the elongated slot 41 of rocking bar, like this, flap 2 has just limited rocking bar 4 and has reset to horizontal level, the boss 43 of rocking bar also just can't insert in the stopper slot 51 of screw 5, screw is in idling conditions, if pass in and out the car operation, screw idle running can't realize passing in and out the car operation.
When the earthed switch separating brake, return spring 9 pulling flaps 2 rotate counterclockwise, flap 2, interlock plate 1 all reset to the position shown in Fig. 1 solid line, this moment, rocking bar 4 just can reset to horizontal level shown in Figure 3, the boss 43 of rocking bar 4 inserts in the stopper slot 51 of screw 5, screw 5 no longer dallies, thereby can pass in and out the car operation.
