With reference to figure 1, a kind of mechanical emergency starting device is present embodiments provided, is arranged 1 on star triangle contactor, with
Shaft 2 on star triangle contactor 1 connects, for control the moving contact 3 of star triangle contactor 1 and the connection of static contact 4 or
It disconnects, this starter includes an operating mechanism and transmission mechanism, and the operating mechanism includes a shell 5, vertical active
Bull stick 6,6 bottom end of active bull stick drive connection, one lateral driven bull stick 7.Specifically, it is equipped with the conical surface in the bottom of active bull stick 6
Gear, while it also being provided with a conical surface gear in 7 one end of driven bull stick, the engagement of two conical surface gears is driven into line direction, in order to
It is laborsaving operable, there is one handle 8 in the upper socket of active bull stick 6.Active bull stick 6 is placed in driven bull stick 7 on shell 5,
And driven bull stick 7 and the exposed part of active bull stick 6.
The transmission mechanism includes a substrate 9, and the shell 5 that substrate 9 is fixed on operating mechanism connects, and 9 top of substrate is set
There are a push rod A10, the lower parts push rod A10 to be equipped with a push rod B11, push rod B11 can be rotatably solid by a connection piece 12 here
Be scheduled on substrate 9, connector 9 is fixedly connected with push rod B11, as shown in Fig. 2, under original state, the lower face of push rod A10 with push away
The upper surface of bar B11 contacts；Push rod A10 is fixed on the head end of driven bull stick 7, and push rod A10 head ends, which move downward, pushes push rod B11
Head end rotate down, i.e., the head end of push rod A10 is walked on the upper surface of push rod B11, and push rod B11 walks downwards, drive connect
Fitting 9 rotates.It is transmission mechanism original state schematic diagram with reference to figure 2；Fig. 3 is transmission mechanism working state schematic representation：
As the improvement of scheme, in the bottom of active bull stick 6, it is symmetrically equipped with a driven bull stick 7, two driven bull sticks again
7 is symmetrical centered on active bull stick 6, and is all connected with a transmission mechanism on each driven bull stick 7, and each rotating mechanism is respectively
A star triangle contactor 1 is contacted, this can be designed so that a mechanical starting device can control two star connection deltas simultaneously
Tentaculum 1.
A kind of star triangle contactor is additionally provided according to the another aspect of the technical program, which includes above-mentioned appoint
One mechanical emergency starting device.
As the improvement of scheme, the contactor includes a shell 13, and 13 top and the bottom of shell are equipped with a shaft 13, described
Shaft 2 one end expose outside shell 13 after with the fixation of connector 12, be fixed with triangular support bracket 14, triangle branch in shaft 2
One angle of the lower part of support 14 is collar design, and lantern ring is sleeved on 2 outside of shaft and realizes fixation.14 upper end of triangular support bracket supports
There is moving contact 3, static contact 4 to be fixed on shell 13, be located at the lower section of moving contact 3, when push rod A10 push push rod B11 head ends to
When lower movement, push rod B11 drives shaft 2 to rotate, and shaft 2 drives the upper end of triangular support bracket 14 to be rotated to lower, pulls dynamic
