Abstract
The utility model discloses a redundant lock device of a passive spiral door mechanical locking device, which comprises a stand, an adaptive nut, a screw, a fixed baffle plate and a lock plate, wherein the fixed baffle plate and the screw are arranged on the stand, the adaptive nut is sleeved on the screw, and the lock plate and the adaptive nut are rigidly connected. When the lock device is locked in place, the positions of the lock plate and the fixed baffle plate do not interfere with each other. The lock device also comprises a magnetic induction switch, the magnetic induction switch is arranged on the fixed baffle plate, and magnetic steel is arranged on the lock plate. When the lock device is locked in place, the position of the magnetic steel coincides with the position of the magnetic induction switch. The fixed baffle plate is arranged in the opening direction of a spiral door. In the utility model, a locking means is added on the original lock device, and the unlocking of a mechanical locking mechanism of the passive spiral door is prevented. The redundant lock device has simple structure, fewer mechanical parts, not high processing accuracy requirements and convenience for maintenance.
Description
Technical field
The utility model relates to a kind of locking device, in particular a kind of locking device that is applicable to passive spiral door machine.
Background technology
At present, on the rail vehicle many worm drive door machine use very extensive, like various vehicle doorns, shield door, civilian door etc.All there be the locking and the release problem of door in the door machine of all worm drive; Be that worm drive door machine adopts screw mandrel that car door is carried out transmission, and car door is after closing, screw mandrel still can be rotated; Therefore only need apply external force and just can door be opened, exist certain potential safety hazard.Locking mechanism of passive spiral door machine relies on the principle of lead angle less than the angle of friction self-locking at present; Pin the self adaptation nut through becoming the lift angle screw rod; If the security incident that will cause the door lock accident to be opened takes place in the roller bolt of self adaptation nut fracture or failure mode such as come off.
Summary of the invention
Goal of the invention: the purpose of the utility model is to overcome the deficiency of prior art, provides a kind of simple and reliable, easy to operate, and need not the spiral door machine locking device redundant latch device in additionaling power source.
Technical scheme: the utility model is realized through following technological means:
A kind of redundant latch device of passive spiral door machine locking device; Comprise frame, self adaptation nut, screw mandrel, fixed stop and jam plate; Said fixed stop and screw mandrel are arranged on the frame, and the self adaptation nut sleeve is on screw mandrel, and said jam plate and self adaptation nut are rigidly connected; When the locking device locking put in place, interfered each other jam plate and fixed stop position.
Said locking device also comprises magnetic induction switch, and magnetic induction switch is arranged on the fixed stop, and magnet steel is set on jam plate, and when the locking device locking put in place, said magnet steel overlapped with the magnetic induction switch position.
Said fixed stop is arranged on the opening direction of spiral door.
Beneficial effect: the utility model has increased a kind of locking means on original locking device; Promptly the self adaptation nut when locking mechanism of passive spiral door machine is in non-locking states; Jam plate and fixed stop stagger on periphery; Do not have the overlapping region, fixed stop can not interfered with jam plate, and the self adaptation nut of locking mechanism of passive spiral door machine can move freely.When the self adaptation nut of locking mechanism of passive spiral door machine is in locking states; Jam plate and fixed stop overlap on periphery; When the locking mechanism of passive spiral door machine locking lost efficacy, fixed stop and jam plate were interfered, and prevent the locking mechanism of passive spiral door machine release.The utility model is simple in structure, mechanism element is few, requirement on machining accuracy is not high, easy to maintenance.

The specific embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
The utility model relates to a kind of redundant latch device of passive spiral door machine locking device; Described device comprises frame, self adaptation nut 3, screw mandrel 4, fixed stop 1 and jam plate 2; Said fixed stop 1 and screw mandrel 4 are arranged on the frame, and self adaptation nut 3 is enclosed within on the screw mandrel 4, and said jam plate 2 is rigidly connected with self adaptation nut 3; When the locking device locking put in place, jam plate 2 was interfered with fixed stop 1 position each other.
Said jam plate turns to the position of fixed stop and position interference, a feasible door position relative fixed, and specifically, described jam plate is arranged on the opening direction of door.
The described fastening devices of the utility model also comprises magnetic induction switch 5 and magnet steel 6; Magnetic induction switch 5 is arranged on the fixed stop 1; Magnet steel 6 is arranged on the jam plate 2, and when the locking device locking put in place, said magnet steel 6 overlapped with magnetic induction switch 5 positions; So just give control device with the locking signal that puts in place, be convenient to the real-time status of control device recognitiion gate.
When at closing time electronic, change lift angle screw rod is just changeing drive self adaptation nut 3 and is being moved to the locking section by the great-lift angle section, closes until getting into locking section door lock; Simultaneously; Jam plate 2 turns on the position with fixed stop 1 interference, thereby the opening direction of door is locked, so; Even it is not dead with door lock to become the lift angle screw rod, described door also can't be opened; When electric open-door, become the counter-rotating of lift angle screw rod and drive self adaptation nut 3 and leave locking section and counter motion and accomplish and open the door simultaneously, jam plate 2 is rotated away from interference position, and door can normally be opened.
