Two-way anti-shearing property circuit and in elevator control circuit；When elevator hall, gate are not completely closed, lift car move up or under
When the pinch roller that moving switchs elevator car safety leaves safe pressing plate, lift car is pacified in the two-way anti-shearing property circuit of elevator
The normally closed contact conducting of full switch, the relay coil adhesive for then acting control rope brake makes in rope brake executing agency
Electromagnetic trip coil energized action, the executing agency of rope brake is worked, the release of dropout mechanical device, rope brake is by steel wire rope
Tightly clamp.
Safe pressing plate is elongated metal plate, is fixed on by support frame on wall, safe pressing plate two ends are smoothly tilted down.
The two-way anti-shearing property circuit of elevator is switched by overhauling elevator, elevator car safety switch a normally closed contact,
A normally closed contact of door lock relay, control rope brake actuating relay coil and control rope brake are moved in elevator control circuit
Make a normal opened contact, the electromagnetic trip coil composition of relay, overhauling elevator switch, normally closed the connecing of elevator car safety switch
Point, the normally closed contact of door lock relay, control rope brake actuating relay coil are sequentially connected in series, and control rope brake actuating relay
Normal opened contact connected with electromagnetic trip coil after be connected in parallel on overhauling elevator switch, elevator car safety switch normally closed contact,
On the normally closed contact of door lock relay, control rope brake actuating relay coil.
One normally closed contact of rope brake safety switch is serially connected on control rope brake actuating relay coil.
Rope brake, elevator car safety switch are prior art.
The positive effect of the present invention is：The two-way anti-shear protective system of elevator, design is simple, convenient to install and maintain, action
Simply, safe and reliable, manufacturing cost is low；Efficiently solve at present because elevator cab door is not yet closed and accidental movement of elevator cage
Cause to shear the technical problem hurted sb.'s feelings, ensured the security of elevator operation, protected the life security of occupant.
Brief description of the drawings
Scheme of installation of the accompanying drawing 1 for electromagnetic trip coil of the invention on rope brake；Accompanying drawing 2 is elevator of the invention
Car safety switchs the scheme of installation with safe pressing plate；Accompanying drawing 3 is safe pressing plate partial enlarged drawing；Accompanying drawing 4 is anti-for the present invention
Shearing property circuit theory diagrams.
Embodiment
The present invention implementation process be：As shown in Figure 2, in every layer of hoistway door 10 above edge well enclosure 8 on
A safe pressing plate 9 is respectively mounted, a lift car peace corresponding with safe pressing plate 9 is installed in the top sides of lift car 13
Full switch 12；One rope brake 2 is installed on elevator main frame 7, an electromagnetism is installed in the executing agency 6 of rope brake 2 and taken off
Fastening wire circle (JSDQ) 5（As shown in Figure 1）；The two-way anti-shearing property circuit of elevator and in elevator control circuit；Safe pressing plate
9 be elongated metal plate, is fixed on by support frame 14 on well enclosure 8, the safe two ends of pressing plate 9 are smoothly tilted down（Such as the institute of accompanying drawing 3
Show）.
When elevator hall, gate are not completely closed, lift car 13, which moves up or moved down 400mm, makes elevator car safety switch 12
On pinch roller 11 when leaving safe pressing plate 9, the normally closed of elevator car safety switch 12 connects in the two-way anti-shearing property circuit of elevator
Point conducting, the relay coil adhesive for then acting control rope brake makes the electromagnetic trip in the executing agency 6 of rope brake 2
The energized action of coil 5, rope brake 2 tightly clamps steel wire rope 1, lift car 13 is parked in a home.
The two-way anti-shearing property circuit electrical schematic diagram of elevator as shown in Figure 4, by overhauling elevator opened by anti-shearing property circuit
Close a normally closed contact of door lock relay in K, normally closed contact AK1, an elevator control circuit of car safety switch 12
A normal opened contact JSXQ1, the folder of JSM1, control rope brake actuating relay coil JSXQ and control rope brake actuating relay
A normally closed contact JSK1, the electromagnetic trip coil (JSDQ) 5 of rope device safety switch 3 are constituted, overhauling elevator switch K, car peace
The normally closed contact AK1 of full switch 12, the normally closed contact JSM1 of door lock relay, the normally closed contact JSK1 of rope brake safety switch 3,
Control rope brake actuating relay coil JSXQ is sequentially connected in series, and controls the normal opened contact JSXQ1 and electricity of rope brake actuating relay
Magnetic tripping coil (JSDQ) 5 is connected in parallel on overhauling elevator switch K, the normally closed contact AK1 of car safety switch 12, door lock after connecting
The normally closed contact JSM1 of relay, the normally closed contact JSK1 of rope brake safety switch 3, control rope brake actuating relay coil
JSXQ。
The present invention operation principle be：The Room, gate are in energization door opening state during elevator normal flat bed, but at loop of the door lock
In off-state, now safe pressing plate 9 is pushed down at the pinch roller 11 on elevator car safety switch 12, elevator car safety switch 12
In off-state, now the electromagnetic trip coil (JSDQ) 5 on rope brake 2 is in the dropout machine on power failure state, rope brake 2
Tool device 4 is failure to actuate.When elevator because the abnormal condition Room, gate are in door opening state, lift car 13 moves up or moved down super
When crossing 400mm, the pinch roller 11 on elevator car safety switch 12 leaves safe pressing plate 9, elevator car safety switch 12 it is normally closed
Point AK1 is connected, and the normally closed point JSM1 of door lock relay of loop of the door lock is also at on-state, now controls rope brake action relay
Device coil JSXQ obtains electric, connects the normal opened contact JSXQ1 of control rope brake actuating relay, while the two-way anti-shearing control of elevator
The energized action of electromagnetic trip coil (JSDQ) 5 in circuit processed, makes the executing agency 6 of rope brake work, dropout mechanical device 4
Release, rope brake 2 is acted, and clamping steel wire rope 1 ensures that lift car 13 is parked in a home.Dropout mechanical device 4 discharges
While, triggering rope brake safety switch 3 is acted, and the normally closed contact JSK1 of rope brake safety switch 3 disconnects, and control rope brake is moved
Make relay coil JSXQ power-off, the two-way anti-shearing property circuit dead electricity of elevator.After accident treatment is complete, manually can just make be
System recovers.
