Description
Technical field
The invention belongs to the elevator field, relate in particular to elevator car door system, be specifically related to lever elevator cage door mechanical lock.
Background technology
Elevator cage door lock machinery is the most basic secure item of elevator, its objective is to prevent that elevator door is opened under the effect of external force, to guarantee occupant safety.At present, the design of elevator cage door mechanical lock mainly contains following several: 1. Room door lock is taken turns and a door cutter linkage type.This structural principle requires door cutter and gate lock to adjust simultaneously, and influences each other, and surpasses the more requirement that can not satisfy dark car of 5mm fault about car depth is larger.2. Spring driving type.Usually drive the lock body slide block by Compress Spring, discharge latch hook by the interaction of hitting bow and lockwheel on the door gear of the Room, the fault of the door of not opening when this structural principle can flat bed occur when spring failure or guide piece insufficient lubrication.3. indirect proof type.Electrical contact is installed on the slide block, uses mode indirectly to prove the position of latch hook, can not prove the depth of engagement of latch hook and joggle piece, can not satisfy the requirement of standard.
Above-mentioned three kinds of modes, Shortcomings part separately has more or less hidden danger to the safe in operation of elevator, in the epoch of day by day emphasizing elevator safety, seems and day by day falls behind.
Summary of the invention
For the deficiencies in the prior art part, the special lever elevator cage door mechanical lock that proposes of the present invention, it can not only address the deficiencies of the prior art, and also has other many useful effects.
Lever elevator cage door mechanical lock comprises slide lock hook assembly 1, rotation lock hook assembly 7, slide plate 4, base plate 12, hits bow 11, hits bow 11 and is fixed on transfixion on every layer of Room door upper sill frame, and described slide lock hook assembly 1 is provided with electro-pneumatic contact 2; Described rotation lock hook assembly 7 is provided with electric break back contact 3, lockwheel 6, rotating shaft 8; Base plate 12 is fixed on car door rail or the upper ridge plate, and anchor fitting has the first guidepost 5, the second guidepost 10 on the base plate 12, and slide plate 4 horizontally slips by the supporting movement guiding of the first guidepost 5 and the second guidepost 10, is installed with stop bit post 9 on the slide plate 4; Rotation lock hook assembly 7 is connected with slide plate 4 by rotating shaft 8, and the anglec of rotation of rotation lock hook assembly 7 is limited by stop bit post 9; After slide lock hook assembly 1,7 engagements of rotation lock hook assembly, electric break back contact 3 and electro-pneumatic contact 2 are connected.
On the basis of the above, the present invention can do following improvement: described slide lock hook assembly 1 has the lower lock hook 13 that protrudes vertically upward, lower lock hook 13 has angled end-face 130, described rotation lock hook assembly 7 has the upper lock hook 72 that protrudes vertically downward, it is suitable that upper lock hook 72 has angled end-face 720, two angled end-faces, and 72 engagements of lower lock hook 13 and upper lock hook are greater than after 7 millimeters, electric break back contact 3 and electro-pneumatic contact 2 are connected, and described angled end-face 130 contacts with angled end-face 720.
Above-mentioned the first guidepost 5, the second guidepost 10 all protrude and perpendicular to described base plate 12, the cross-sectional plane of the two is circular, square, oblong.Slide plate 4 is provided with the first breach 41 and the second breach 42, thereby slide plate 4 is nested on the base plate 12 with the first guidepost 5, the 10 coupling activities of the second guidepost respectively by the first breach 41, the second breach 42.
Above-mentioned stop bit post 9 protrudes and perpendicular to base plate 12, the cross-sectional plane of stop bit post 9 is circular, square, oblong, correspondingly, offers position-arresting hole 71 on the described rotation lock hook assembly 7, position-arresting hole 71 and stop bit post 9 are suitable, and the area of position-arresting hole 71 is slightly larger than the sectional area of stop bit post 9.
Patent elevator cage door mechanical lock device of the present invention, the door cutter combined action of moving and being contained on the floor door in the lift car leveling district by car door is opened door lock assembly, door lock does not collide with the door cutter when cage operation, at non-leveling zone owing to there not being the effect door lock assembly of a cutter not open, at latch hook the electro-pneumatic contact is housed, the rotation of the movement of slip latch hook, rotation latch hook all can make contact action, only closes at car door to put in place and latch hook during at locked position, and electrical contact just is in closure state.Gate is closed when putting in place, because the effect of slip latch hook forces the rotation latch hook to be reset to engagement.The present invention does not rely on other external force such as spring, according to being installed in two electrical contacts on the latch hook, directly proves the depth of engagement of two latch hooks, has greatly improved the safety of mechanical door lock.
Because above-mentioned beneficial effect is in the gate mechanical lock of the various elevators of widespread use of the present invention.
