Detailed Description
As shown in fig. 1 and 2, a one-key sequential control double-confirmation device for an isolating switch is characterized in that a motor 2 is fixedly connected in a box body 1, a main shaft at the bottom of the motor 2 is connected with a worm 3 through a speed reducer, a crank arm 14 is supported in the box body 1 through a bearing seat, one end of the crank arm 14 is provided with a worm wheel 8, and the worm wheel 8 is meshed with the worm for transmission; the other end of the crank arm 14 is an eccentric wheel 5, an open slot is arranged on the eccentric wheel 5 and is connected with a strip hole at the bottom of the swing rod 6 through a pin shaft, and the upper part of the swing rod 6 is connected with a transmission output shaft 12; the upper part of the swing rod 6 beyond the transmission output shaft 12 is connected with a deflector rod 9 of the vertical swing rod 6, and micro switches 4 are respectively arranged at two movement limit positions of the deflector rod 9. The micro switch 4 consists of a position signal micro switch 4-1 and a motor cut-off micro switch 4-2, and the length of the deflector rod 9 can simultaneously stir the position signal micro switch 4-1 and the motor cut-off micro switch 4-2 on the same side, so that a double confirmation function is realized.
As shown in fig. 3 and 4, a buffer 15 is arranged in the box 1, a buffer rod 19 is arranged at the control end of the buffer 15, the outer end part of the buffer rod 19 is connected with a double-lug plate 16, a vertical strip hole 17 is arranged on the double-lug plate 16, and a deflector rod 9 passes through the strip hole 17 and is connected with the top of the swing rod 6.
The working process is as follows: the motor 2 drives the worm wheel 8 through the worm 3 below, and the worm wheel drives the crank arm 6 to rotate. One end of the buffer 15 is fixed on the side wall of the side box, and the other end is connected with the crank arm 6 through the double lugs 16, and the crank arm 14 and the eccentric wheel 5 are operated to be of an eccentric structure, so that the crank arm 6 is pushed to rapidly act, meanwhile, the buffer is put into buffering, and when the front crank arm rotates for 108 degrees from the horizontal position. Crank arm 14 also rotates through 108. The transmission output shaft 12 rotates through 75 degrees, the deflector rod 9 on the crank arm 6 is contacted with the position signal micro switch 4-1 and the motor cut-off micro switch 4-2 at the same time, the position signal is sent out through the position signal micro switch 4-1, then the motor cut-off micro switch 4-2 is used for sending out a motor cut-off signal, the power supply of the motor 2 is switched off, and at the moment, the power failure of the motor 2 is used as an external generator braking instruction, so that the external generator is braked. When the crank arm 6 rotates to the position signal micro switch 4-1 at the other side and the motor cuts off the contact switching position of the micro switch 4-2, preparation is made for the next operation.
