Abstract
The invention provides a lift car door-opening accidental moving protecting device in order to eliminate potential safety hazards caused by accidental moving of a lift car when the lift car is open. The lift car door-opening accidental moving protecting device is characterized in that a hoistway positioning plate (16) provided with a positioning hole is installed in a lift hoistway, and the lift car door-opening accidental moving protecting device is installed on a lift car; when a door of the lift car is opened, a cam driving block (1) which is linked with the door of the lift car moves to the right to drive a cam (3) to conduct counterclockwise rotation, the cam (3) drives a positioning rod (12) to slide to the right and be inserted into the positioning hole of the hoistway positioning plate (16) through a positioning rod rolling wheel (6), the lift car is locked, and accidental moving when the lift car is open can be effectively prevented; when the door of the lift car is closed, the positioning rod (12) slides to the left under the action of a reset compression spring (13) to break away from the hoistway positioning plate (16), unlocking of the lift car is achieved, and the lift car can operate normally.
Description
Technical field
The present invention relates to a kind of elevator resist technology field, especially a kind of lift car enabling accidental movement fender guard.
Background technology
Along with the development of society, high buildings and large mansions get more and more, and elevator has become most important vertical transportation transportation means in building.Elevator, while bringing convenience to people's lives, also brings certain potential safety hazard to passenger---and the accidental movement that accidental movement of elevator cage especially opens door is exactly one of them.
China Patent No. CN201110299987.8 provides a kind of device preventing accidental movement of elevator cage, this device utilizes the slide bar being arranged on car to insert and is arranged in the lock hole of hoistway, solves the problem of ideally accidental movement of elevator cage preferably.But also there is the action of this mechanism and the opening and closing of car door cannot the defect of action without this mechanism when direct relation, dead electricity, therefore when also having car door to open, car still can move and the possibility that cannot prevent accidental movement of elevator cage during dead electricity, makes the reliability of its practical application greatly reduce.
Summary of the invention
The potential safety hazard of the movement that meets accident is open for getting rid of elevator cab door, the invention provides a kind of lift car enabling accidental movement fender guard, it is characterized in that: the hoistway locating plate (16) having knock hole is installed in elevator hoistways, lift-mounting car enabling accidental movement fender guard on the elevator car, fender guard is by the actuated by cams block (1) with lift car door linkage, be fixed on the fender guard pedestal (2) of car, cam (3), camshaft (4), for the shaft block ring (5) that cam and camshaft are located, the radius stay roller (6) directly contacted with cam, roller shaft (7), for the shaft block ring (8) that roller and roller shaft are located, radius stay guide pipe left end cap (9), be installed on the electric break back contact (10) of left end cap, be installed on insulation conduction touch panel (11) of radius stay shaft shoulder end face, radius stay (12), reset Compress Spring (13), guide pipe (14), radius stay guide pipe right end cap (15) forms, wherein the horizontal center line of radius stay roller shaft (7) is lower than the horizontal center line of camshaft (4).When car door is opened, move right with the actuated by cams block (1) of lift car door linkage, actuating cam (3) left-hand revolution, cam (3) promotes radius stay (12) by radius stay roller (6) and slides to the right and insert the knock hole of hoistway locating plate (16), lift car is locked, accidental movement when can effectively prevent elevator cab door from open; When car door is closed, radius stay (12), under the effect of reset Compress Spring (13), slides left, and depart from hoistway locating plate (16), lift car latch-release, can normally run.
