Specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of electromagnetic lock for rail transportation half-height safety door of structure of the present invention, it include by
The rectangle electromagnetic lock frame that lower cover plate 7, upper cover plate 15, left cover 11 and right cover plate 20 are fixedly connected into.Electromagnet 1 passes through electromagnet
Bracket 2 is fixed on the right side of electromagnetic lock frame.Shaft locking sleeve 14, limit switch before top is fixedly connected sequentially from left to right in electromagnetic lock frame
Bracket 18 and rear shaft locking sleeve 19.Level is equipped with lock shaft 13 in the through-hole at 19 middle part of preceding shaft locking sleeve 14 and rear shaft locking sleeve, lock shaft 13
One end stretches out electromagnetic lock outer frame and is fixedly connected with lock tongue 12.13 middle section of lock shaft connection limit switch hits iron 17, and limit switch hits iron
It is respectively symmetrical bevel structure on four angles of 17 horizontal planes.The contact of four rolling structure is equipped on limit switch bracket 18
The matching of four bevel structures on iron 17 is hit in formula sensor 16, the position of four touch sensors 16 with limit switch respectively
It closes.It successively links through lower shake-changing arm 4, connecting rod 6 and upper rocker arm 9 and lock shaft 13 lower end for the electromagnet shaft being disposed vertically on electromagnet 1
Connection.Lower shake-changing arm 4 be L-type, one end be provided with slotted hole by iron pin 3 and the lower end of electromagnet shaft it is hinged, in the middle part of
It is provided with circular hole to be hinged on lower cover plate 7 by pin shaft 5, the other end is provided with circular hole and connect with connecting rod 6.Upper rocker arm 9 is L-type,
One end is provided with circular hole and connect with connecting rod 6, and middle part is provided with circular hole and passes through shaft 10 and the bracket 8 being fixed on lower cover plate 7 hingedly,
Its other end is provided with slotted hole and is moved in the long hole at 13 middle part of lock shaft by pivot pin.
Referring to Fig. 3 and Fig. 4, the electromagnetic lock of photo-electric non-contact sensor 22 is used for another structure of the present invention.
The structure of electromagnetic lock of the present invention, lower shake-changing arm 4 and upper rocker arm 9 pass through together with the switching of connecting rod 6, connect into kinematic pair,
Realize the locking and unlocking motion of electromagnetic lock.The contact wear of lower shake-changing arm 4 and electromagnet 1 in order to prevent, connection contact position can
Axle sleeve is set.Once axle sleeve is worn, replacement is low in cost.
Limit switch in electromagnetic lock of the present invention hits 17 top center of iron equipped with circular through hole, and lateral middle is equipped with groove,
The inclined-plane of quadrangle is used to detect with the location triggered of four touch sensors 16 in its plane, and transverse concave groove is matched with lock shaft 13
It closes, is fixed together by its top circular through-hole with lock shaft 13, with lock shaft 13 together in preceding shaft locking sleeve 14 and rear shaft locking sleeve 19
It is moved in the channel of composition.
Motion principle when electromagnetic lock of the present invention works is as follows:
When being unlocked, firstly, 1 snap action of electromagnet being mounted on sliding door, under being pulled by 1 axis of electromagnet
Rocker arm 4, Rocker arm 4 rotation drive upper rocker arm 9 to rotate by connecting rod 6.It is axial traversing that upper rocker arm 9 stirs lock shaft 13, lock shaft before retracting
In set 14, lock tongue 12 is driven to withdraw, completes unlock.At this point, electric motor starting, sliding door is opened.In locking, electromagnet 1 is powered off,
Its axis is flicked by the compressed spring of electromagnet 1, system acting, lock tongue 12 stretches out, and realizes locking functions.
