Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
This chain maintenance protection device, it includes base 1, maintenance latch 2, operation handle 3, travel switch 4, switch installation board 5 and latch sliding sleeve 6；Left and right two bases 1 are fixed with upper and lower two latch sliding sleeves 6, maintenance latch 2 it is slidably fitted with in latch sliding sleeve 6, the axis of upper and lower two maintenance latches 2 is set in parallel, maintenance latch 2 is fixed with operation handle 3, offering latch chute 6.1 on latch sliding sleeve 6 between left and right two bases 1, operation handle 3 is fixed on the maintenance latch 2 of correspondence after latch chute 6.1；Being fixed with upper and lower two pieces of switch installation boards 5 wherein on a base 1, be respectively and fixedly provided with travel switch 4 on every piece of switch installation board 5, travel switch 4 coordinates with corresponding maintenance latch 2, is provided with travel switch trigger architecture on maintenance latch 2.
Described maintenance latch 2 includes the latch that coaxially connects of order left section 2.1, first linkage section 2.2, latch stage casing 2.3, second linkage section 2.4 and latch right section 2.5, the diameter that latch is left section 2.1 right with latch section 2.5 is identical, the diameter in latch stage casing 2.3 is less than the diameter of latch left section 2.1, first linkage section 2.2 and the second linkage section 2.4 are Rotary-table, the diameter that the left part diameter of the first linkage section 2.2 is left with latch section 2.1 is identical, the right part diameter of the first linkage section 2.2 is identical with the diameter in latch stage casing 2.3, the left part diameter of the second linkage section 2.4 is identical with the diameter in latch stage casing 2.3, the diameter that the right part diameter of the second linkage section 2.4 is right with latch section 2.5 is identical.
The length that latch is left section 2.1 is more than the length of latch right section 2.5, and described operation handle 3 is fixed on latch left section 2.1.
The described operation handle 3 sliding stroke in latch chute 6.1 equal to the left part of the first linkage section 2.2 to the distance between the right part of the second linkage section 2.4.
Maintenance latch 2 forms ring-shaped depression in the position of the first linkage section 2.2, latch stage casing 2.3 and the second linkage section 2.4, and the triggering end of travel switch 4 is positioned at this ring-shaped depression, and this ring-shaped depression constitutes travel switch trigger architecture.When making maintenance latch 2 sliding to the left by operation handle 3 and stretching out base 1, maintenance latch 2 is inserted in the tooth mouth of sprocket wheel 7, and the triggering end of travel switch 4 is located just in this ring-shaped depression, and travel switch 4 is disconnected, and the motor power of elevator is disconnected.When by operation handle 3 make maintenance latch 2 to the right sliding return in situ time, maintenance latch 2 exits in the tooth mouth of sprocket wheel 7, triggering end in contact first linkage section 2.2 of travel switch 4, and travel switch 4 is connected, and the motor power of elevator is connected.
In the present invention, two maintenance latches 2 are placed in the latch sliding sleeve 6 in base 1, two handles 3 are threaded connection and keep in repair latch 2 and link together, and switch installation board 5 is threadedly attached on base 1, and travel switch 4 is threadedly attached on switch installation board 5.
When specifically applying, hold two handles 3 in latch chute 6.1 in slide, thus drive maintenance latch 2 to extend, two maintenance latches 2 be locked in sprocket wheel 7 two tooth mouths in, thus sprocket wheel 7 is pinned.
When after maintenance latch 2 elongation, the triggering end of travel switch 4 is positioned at position, latch stage casing 2.3, travel switch 4 not contact maintenance latch 2, if now starting elevator cannot start, only when maintenance latch 2 is under the drive of latch handle 3, and when being retracted in situ, the first linkage section 2.2 of maintenance latch 2 touches travel switch 4, when so restarting, elevator just can be run normally.After having keeped in repair elevator, if maintenance latch 2 is not retracted, elevator motor on startup can transship, thus is effectively protected motor.
