Embodiment
The invention will be further described below in conjunction with accompanying drawing.
It comprises main supporting splint, tripping spring 1, separating brake spring base 4 and switching-in spring 24, combined floodgate spring Connection Block 25, wherein between main supporting splint, be provided with first working shaft 7, second working shaft 20, in closing on the zone of first working shaft and second working shaft, main supporting splint bottom is provided with the little axle 9 of separating brake pallet, the little axle 14 of combined floodgate pallet, also has brake-dividing locking axle 12, combined floodgate lock shaft 17, its first working shaft 7 is provided with dihedral connecting lever 6, the dihedral connecting lever is provided with the angle for one jiao and turns hinge I axle 5, and hinged with fork 19 1 ends; The dihedral connecting lever is provided with the angle for one jiao and turns hinge II axle 8, and hinged with separating brake spring base 4; Second working shaft 20 is provided with energy storage connecting lever 21, and energy storage connecting lever 21 is provided with hinge axis 22, and hinge axis 22 is with hinged with the chute of fork 19 other ends and combined floodgate spring base 23; Sluice separating spring Connection Block 2 is provided with sluice separating spring hinge axis 3, and is hinged with separating brake spring base 4; Combined floodgate spring Connection Block 25 is provided with switching-in spring hinge axis 26, and is hinged with combined floodgate spring base 23; The little axle 9 of separating brake pallet is provided with separating brake pallet 10, and brake-dividing locking axle 12 is provided with separating brake locking bar 11, and is slidingly matched with separating brake pallet 10; The little axle 14 of combined floodgate pallet is provided with combined floodgate pallet 15, and combined floodgate lock shaft 17 is provided with combined floodgate locking bar 16 and is slidingly matched with combined floodgate pallet 15; Tripping electromagnet 13 contacts with separating brake locking bar 11, and making electromagnet 18 contacts with combined floodgate locking bar 16.
When driven by motor energy storage connecting lever 21 clockwise directions rotate, drive combined floodgate spring base 23 and move down and spur combined floodgate spring Connection Block 25,24 energy storage of compression switching-in spring; At this moment, combined floodgate locking bar 16 locking combined floodgate pallets 15, combined floodgate pallet 15 locking hinge axles 22, motor stall.As shown in Figure 4.
Closing operation, making electromagnet 18 is subjected to electricity, promotes combined floodgate locking bar 16 and rotates, and the switching-in spring 24 upwards component of effect will back down combined floodgate pallet 15, and drive rocker 19 drives dihedral connecting lever 6, the first working shafts 7 and rotates, and realizes closing operation.Simultaneously, hinge II axle 8 and separating brake spring base 14 and 1 energy storage of sluice separating spring Connection Block 2 compression tripping springs are turned in the angle on the dihedral connecting lever 6.After closing a floodgate on earth, separating brake pallet 10 and separating brake locking bar 11 lock 6 lockings of dihedral connecting lever simultaneously closing position and reach the tripping spring of energy storage, see Fig. 3.After combined floodgate was finished, motor drove energy storage connecting lever 21 again and gives the switching-in spring energy storage, sees Fig. 5, and energy storage ends, combined floodgate pallet 15 lockings that resetted again.
Sub-switching operation, sub-switching operation have two kinds of situations: first kind be mechanism close a floodgate finish after, separating brake immediately, another kind be mechanism close a floodgate finish after, treat that switching-in spring has stored up separating brake afterwards once again.
First kind of situation is after tripping electromagnet 13 is subjected to electricity, and tripping electromagnet 13 pushes separating brake locking bar 11 and rotates, and at this moment tripping spring 1 makes dihedral connecting lever 6 back down 10 rotations of separating brake pallet by fork 19, and drives the K switch separating brake.Energy storage connecting lever 21 is push-jump to the less important initial position that makes switching-in spring 24 energy storage again by rocking bar 19 by dihedral connecting lever 6, sees Fig. 2.
Second kind of situation is that first kind of difference of separating brake is that energy storage connecting lever 21 is not pushed, and has been in the combined floodgate arm-to-arm, is that rocking bar 19 moves downward position shown in Figure 4 with dihedral connecting lever 6 during separating brake.
