Description
Technical field
The present invention relates to a kind of modular construction that is used for the circuit breaker cart of high pressure power transmission and distribution, specifically is a kind of interlocking device of breaker handcart advancing mechanism.
Background technology
Circuit breaker cart in use needs it to be pushed or withdraws from service position on the switch cubicle by propulsive mechanism, and it rotates a driving screw mandrel into and out of action by operating grip and realizes usually.In the switch cubicle running, the propulsive mechanism that does not allow to operate handcart when circuit breaker is in "on" position withdraws from handcart, and be in operable state following time when the propulsive mechanism of handcart, and do not allow circuit breaker to carry out closing operation again, therefore need interlocking device that this process is controlled.The most complex structure of existing interlock, poor reliability are difficult to satisfy higher instructions for use.
Summary of the invention
Technical problem to be solved by this invention is that a kind of simple in structure, easy to operate, reliable interlocking device of breaker handcart advancing mechanism of interlocking is provided.
Interlocking device of breaker handcart advancing mechanism of the present invention includes the driving screw mandrel that a rear end can cooperate with operating grip, be provided with a slide plate that is installed on the handcart panel at the rear that drives screw mandrel, slide plate can move along the guide rail of level is left and right, have on the slide plate one with drive the handle hole that screw mandrel is positioned at same level height, when handle hole moved to over against driving screw mandrel rear end, operating grip can insert handle hole and operate driving screw mandrel; Also have the guide groove of a level on the slide plate, the slide plate inboard is provided with a rotating locking bar over against the position of guide groove, have an operation key can pass guide groove and cooperate with the locking bar outer end and operate locking bar rotation, the rotation of locking bar can drive an auxiliary switch that is connected in the circuit breaker operation mechanism control loop; A crank is installed on the described locking bar, crank rim is equipped with a bearing pin, bearing pin one end is placed in a vertical groove that is arranged on the slide block, and described slide block is fixedly mounted on the slide plate, makes the swing of crank and bearing pin to drive slide plate by slide block and moves.
Also have the pin-and-hole of an and diameter equal on the described slide plate less than the guide groove width with above-mentioned guide groove, be interconnected by the narrow groove of a width between pin-and-hole and the guide groove less than the level of pin-and-hole diameter, also be provided with a bullet pin in the slide plate inboard, bullet pin inboard is pressed with a spring that the bullet pin is outwards ejected, bullet pin arranged outside has the button of a diameter less than the bullet pin, when the aforesaid operations hole when driving screw mandrel, described bullet pin can stretch in the pin-and-hole.
The present invention is simple in structure, easy to operate, and operation that can the rival car propulsive mechanism is carried out positive locking, the security reliability height.
Description of drawings
To be the present invention driving the not outboard structure schematic diagram under the operable state of screw mandrel to Fig. 1;
Fig. 2 is that the present invention is at the outboard structure schematic diagram that drives under the screw mandrel operable state;
Fig. 3 is an inside structure schematic diagram of the present invention.
Embodiment
As shown in the figure, this interlock includes the driving screw mandrel 1 that a rear end can cooperate with operating grip, be provided with a slide plate 2 that is installed on the handcart panel at the rear that drives screw mandrel, slide plate can move along the guide rail of level is left and right, have on the slide plate one with drive the handle hole 3 that screw mandrel is positioned at same level height, when handle hole moved to over against driving screw mandrel rear end, operating grip can insert handle hole and operate driving screw mandrel; Also have the guide groove 4 of a level on the slide plate, the slide plate inboard is provided with a rotating locking bar 5 over against the position of guide groove, have an operation key 6 can pass guide groove and cooperate with the outer end of locking bar 5 and operate locking bar rotation, the rotation of locking bar can drive an auxiliary switch 7 that is connected in the circuit breaker operation mechanism control loop.As shown in Figure 3, a crank 8 is installed on the locking bar 5, and crank rim is equipped with a bearing pin 9, and bearing pin one end is placed in a vertical groove 11 that is arranged on the slide block 10, slide block 10 is fixedly mounted on the slide plate 2, makes the swing of crank and bearing pin to move by slide block 10 driving slide plates 2.Also have the pin-and-hole 12 of an and diameter equal on the slide plate 2 less than the guide groove width with above-mentioned guide groove 4, be interconnected by the narrow groove 13 of a width between pin-and-hole and the guide groove less than the level of pin-and-hole diameter, also be provided with a bullet pin 14 in the slide plate inboard, bullet pin inboard is pressed with a spring 15 that the bullet pin is outwards ejected, bullet pin arranged outside has the button 16 of a diameter less than the bullet pin, when handle hole 3 when driving screw mandrel 1, bullet pin 14 can stretch in the pin-and-hole 12 under the effect of spring 15, makes slide plate to move.
The device course of work of the present invention is: when circuit breaker is in gate-dividing state, pressing the button 16 makes bullet pin 14 withdraw from pin-and-hole 12, to operate key 6 inserts, clockwise rotate 90 degree, the operation key drives locking bar 5 and rotates 90 degree, the rotating drive auxiliary switch 7 of locking bar switches, and makes circuit breaker carry out closing operation again, at this moment operates key and can't extract.Driving slide plate 2 by crank 8 and slide block 10 when locking bar 5 rotates moves, make handle hole 3 over against driving screw mandrel (position shown in Figure 1), at this moment can insert operating grip, drive propulsive mechanism, make handcart arrive the service position, extract operating grip, once more button 16 is pressed, will operate key 6 and turn 90 degrees counterclockwise, can extract the operation key, auxiliary switch is finished 7 switchings simultaneously, and handcart is finished to the service position motion process by test position, and at this moment operating grip can't be operated driving screw mandrel.Handcart is the same to the test position motion process by the service position.
