Locking principle and the process of above-described embodiment are as follows:
Under normal conditions, if breaker transfer dolly 2 is not near switch cubicle 1, the direction of spacing centering block 7 can be made to be vertical, and spacing centering block 7 upwards exposes the centering block hole 210 of horizontal panel, as shown in Figure 2; Latch plate 10 is by the forward thrust effect of back-moving spring 9, be in the front end (locked position of coupler) of its longitudinal stroke, the lengthwise position of spline block 11 aims at the lengthwise position of latch plate splined hole 101, spline block 11 is just arranged in splined hole 101, spline block 11 can not around operating axis center axis thereof, namely operating axis 5, spacing centering block 7 can not rotate, if now circuit breaker 17 is parked on the horizontal panel 21 of transport carriage, then circuit breaker 17 is subject to the longitudinal spacing of position limiting pile 4 and spacing centering block 7, cannot push away transport carriage 2; If circuit breaker 17 is not on transport carriage 2, then by the restriction of spacing centering block 7, circuit breaker 17 also cannot be shifted onto the horizontal panel 21 of transport carriage from switch cubicle 1, as shown in Figure 2, Figure 4 shows.
Two, when wanting circuit breaker 17 to be pushed into inside switch cubicle 1 from transport carriage 2, transport carriage 2 can be shifted near switch cubicle 1 gradually, shift near in switch cubicle 1 process at transport carriage 2, the guiding of the hook pin 13 of operating axis front end and the strip pin-and-hole 16 of switch cubicle can be utilized, as shown in figure 12, make the hook pin 13 of operating axis front end aim at the strip pin-and-hole 16 of switch cubicle, transport carriage 2 could fully lean on into switch cubicle wallboard 15, and transport carriage 2 present position is now called unlocked position.When transport carriage 2 fully contacts with switch cubicle wallboard 15, when transport carriage 2 reaches unlocked position, hook pin 13 is forward through the strip pin-and-hole 16 of switch cubicle wallboard, and arrive the front of switch cubicle wallboard 15, the length of hook pin 13 to the length of strip pin-and-hole 16 to consistent (being namely all horizontal cross), in addition, contacting bar 12 can under the effect of switch cubicle wallboard 15, overcome the forward thrust of back-moving spring 9, back down latch plate 10 backward, make spline block 11 and latch plate 10(comprise splined hole 101) lengthwise position stagger, spline block 11 departs from the restriction of latch plate splined hole 101, so operating grip 2, operating axis 5, spacing centering block 7, spline block 11, the locking main shaft entirety that hook pin 13 forms can operate rotation, now hand rotating operation handle 2 can be used, when operating grip 2 drives locking main shaft unitary rotation 90 degree, the length of hook pin 13 to become vertical (perpendicular to strip pin-and-hole length to), hook pin 13 hooks switch cubicle wallboard 15, use transport carriage 2 cannot depart from switch cubicle 1, as Figure 13, Fig. 8, Figure 10.Meanwhile, the length of spacing centering block 7 is to becoming horizontal direction, and spacing centering block 7 is hidden in below horizontal panel 21; Spacing centering block 7 is in released state, and as shown in Figure 15, Figure 13, Fig. 5, Fig. 3, circuit breaker 17 can pass in and out breaker transfer dolly 2.Pass in and out in the process of breaker transfer dolly 2 at circuit breaker 17, spacing centering block 7 cannot rotate by the compacting of circuit breaker 17 bottom surface, locking main shaft entirety is made to operate rotation, thus ensure that hook pin 13 cannot rotate, namely ensure that hook pin 13 hooks switch cubicle wallboard 15 always, the connection of transport carriage 2 and switch cubicle 1 cannot unlock, and transport carriage 2 can not depart from switch cubicle 1, guarantees that circuit breaker 17 safety is transferred to switch cubicle 1 from transport carriage 2; When circuit breaker 17 moves to after inside switch cubicle 1 completely, spacing centering block 7 is not rotatable by the compacting of circuit breaker 17 bottom surface, and transport carriage 2 and switch cubicle 1 can be made to depart from.
Three, when wanting circuit breaker 17 to transfer to breaker transfer dolly 2 from switch cubicle 1, the step that breaker transfer dolly 2 is chain with switch cubicle 1 is identical with above-mentioned second point, after this, circuit breaker 17 can push breaker transfer dolly 2 to from switch cubicle 1, in this pushing course, spacing centering block 7 cannot rotate by the compacting of circuit breaker equally, locking main shaft entirety cannot operate rotation, thus ensure that hook pin 13 cannot rotate, the connection of transport carriage 2 and switch cubicle 1 cannot unlock, breaker transfer dolly 2 cannot depart from switch cubicle 1, guarantee that circuit breaker 17 safety is transferred to breaker transfer dolly 2 from switch cubicle 1, when circuit breaker 17 moves to after above breaker transfer dolly 2 completely, spacing centering block 7 is not rotatable by the compacting of circuit breaker 17 bottom surface, and transport carriage 2 and switch cubicle 1 can be made to depart from.
In above-described embodiment, the shape of spline block 11 also can change in cross.
