Description
Technical field
Elevator technology field is the utility model is related to, specifically a kind of elevator craning cage door electromagnetic lock.
Background technology
Building hoist is manned, loading the construction equipment being commonly used in building.Wherein cage door lock is
Ensure that cage door will not be opened during cage normal operation, only meet sets requirement (typically in the distance of cage bottom plate and stop
In the range of 0.15m) when the protectors that are opened of Men Caihui.
The door lock on domestic manned, loading cage is all simple mechanical device at present, and cage door lock is arranged on and hung
Cage door side.When cage bottom plate and landing position are run in the position of cage reaching sets requirement, the stop on the upside of stop is spacing
The roller on Tie Tong overvoltage cage door lock jam plate is hit, drives jam plate to rise after roller stress, and neck departs from support plate on jam plate
On pin, rotating shaft can be with flexible rotating on such cage door guard plate, and now cage door can be with normal rotation.But constructed in reality
During, due to pure mechanic structure, installation, regulation are difficult, and sometimes cage door can not be opened or can not opened completely, notably
Under non-resting state it cannot be guaranteed that door lock it is in the closed position all the time, therefore caused by security incident occur repeatedly.
It is domestic at present also to be filled without any cage door lock that solve accurately to control cage door to open completely, close
Put, accident occupies considerable proportion in elevator safety accident caused by cage door lock defect.
The purely mechanic lock that installation is integrally linked by crank, jam plate, connecting lever is that current domestic like product is most widely used
Cage door lock, especially in man-engine.Cage door lock is mainly made up of support plate, crank, jam plate, connecting lever etc..Because crank,
Jam plate and connecting lever belong to linkage, and when neck is stuck in the pin on support plate on jam plate, connecting lever can not rotate, now indirect with connecting lever
Connected upper gateway rotating shaft can not rotate, and have the function that to lock a door.
Cage door lock is fixed by bolts on cage, and when stop position of the cage not in stop, the neck of jam plate is stuck in
On support plate (side for door lock being fixed on by bolt cage door) pin, interlocked with the rotation because jam plate, crank and connecting lever belong to,
So now connecting lever can not rotate, and connecting lever is linked by connecting rod and door shield rotating shaft, and now cage door (opens) place to interior folding
In closed mode.When cage is running to stop on guide rail, the spacing iron that hits presses off the jam plate with roller on the upside of stop, with
Jam plate position rises, and neck and the pin on support plate separate on jam plate, now the connecting lever on connecting rod and door lock can with flexible rotating,
So cage door can opens.
The shortcomings that existing door lock, is, because of pure mechanic structure part, cage door can not be opened or can not opened completely sometimes,
Notably it cannot be guaranteed that door lock is in the closed position all the time and causes the generation of accident under non-resting state.
