Description
Technical field
The present invention relates to a kind of spring operating mechanism and use the breaker of the spring operating mechanism.
Background technique
Separating brake tripping system is the critical system in breaker spring operating mechanism, it will reliably guarantee that breaker is realized and divide
Lock avoids the occurrence of and refuses a point phenomenon because of caused by tripping system failure, and electromagnet is the power resources of separating brake tripping system movement.
The electromagnet of current breaker spring operating mechanism controls pawl by latch assembly, and latch assembly includes lock bolt,
On the rack, one end of lock bolt and pawl realize transmission cooperation to lock bolt rolling assembling by way of block cooperates, and pass through limitation
The movement of pawl, and then pawl holds the spring in energy storage state.Common electromagnet is arranged two, respectively main electromagnet and
Secondary electromagnet, two electromagnet are arranged in series, and after the coil of main electromagnet is burnt out, secondary electromagnet can pass through the main electromagnetism of pushing tow
The lance of iron realizes the driving to lock bolt, and still, for this latch assembly in the lance clamping stagnation of main electromagnet, latch assembly can not
Movement.
The Chinese invention patent application that application publication number is CN109166741A, data of publication of application is 2019.01.08 discloses
A kind of breaker, spring operating mechanism and its latch assembly, the spring operating mechanism include pedestal and rolling assembling the bottom of at
Lock bolt on seat, the lock bolt have the block position to sincere sub- carry out block on the stroke of controlled reciprocally swinging and get out of the way described
Sincere son allows open position, and pedestal is equipped at least two parallel arrangements and the lock bolt can be operated alone is rocked to by block position and gets out of the way
The electromagnet of position, lock bolt and electromagnet support cooperation, this spring actuator by the lance of lance and electromagnet on lock bolt
Two electromagnet of structure are mutually indepedent, and the independence driving to lock bolt may be implemented, but need in the lance swing process on lock bolt
Larger space is wanted, spring operating mechanism is caused to there is a problem of that the components installation space such as lock bolt is big.
Summary of the invention

On 3, there is the connecting plate 11 being fixedly connected with electromagnet mounting base 3 in rack 10.When the installation for carrying out two electromagnet is fixed,
First two electromagnet can be fixed in electromagnet mounting base 3, then electromagnet mounting base 3 is fixed in rack 10 and completes two
Fixed installation of the electromagnet in rack 10 avoids and installation main electromagnet 1 respectively and secondary electromagnet 2 is arranged in rack 10
Mounting base simplifies 10 structure of rack.
In view of main lock bolt 7 needs to support cooperation with pawl 13, along the axial direction for axis 6 of bolting the door in the rack 10 in the present embodiment
It is equipped at intervals with two axis perforation of bolting the door being rotatably assorted with axis 6 of bolting the door, wherein main lock bolt 7 is arranged in two axis of bolting the door and wears
Bolting the door on 6 part of axis between hole, secondary lock bolt 8 are disposed therein one that an axis perforation of bolting the door is perforated away from another axis of bolting the door
It bolts the door on 6 part of axis side.In this way, main lock bolt 7 be in two bolt the door axis perforation between, by two bolt the door axis perforation hole wall can be very
The stability of the good main lock bolt 7 of guarantee.
In other embodiments, the spring operating mechanism can be used for closing operation;Main electromagnet and secondary electromagnet can
Along the axial two sides arranged and be distributed in axis of bolting the door for axis of bolting the door, i.e., the pushing tow face setting at a certain angle of two pawls;It is main
Lock bolt and secondary lock bolt can be arranged at bolting the door on shaft portion between two axis perforation of bolting the door;Main electromagnet and secondary electromagnet
It can be fixed on the rack respectively by electromagnet mounting base or connecting plate.
The specific embodiment of breaker of the invention, breaker include breaker body and spring operating mechanism, this implementation
