Description

A kind of anti-slip moving method of flat bed and device of cabin elevator

Technical field

The present invention relates to a kind of a kind of anti-slip moving method of flat bed of method for safe operation of cabin elevator, particularly cabin elevator.A kind of above-mentioned kind of cabin elevator flat bed device that anti-slip moving method adopts is also provided simultaneously in the present invention.

Background technology

The principle of cabin elevator is exactly an assembly pulley, and the two ends of pulley hang respectively car and counterweight by steel rope.The use of cabin elevator is to rely on motor to drive traction sheave rotation, drives steel rope to move, thereby orders about car and counterweight change in location.

Wherein, the movement of above-mentioned steel rope carrys out transferring energy by friction force between traction sheave and steel rope, and this friction force is traction, and its size is subject to the impact of the factors such as thickness of traction sheave grooving shape and steel rope.Elevator is after place in operation, and because of the reason of mechanical wear, the grooving of traction sheave is out of shape, steel rope abrasion, and traction will weaken like this.In addition, stopping of above-mentioned cabin elevator is to rely on towing machine brake sticking brake, and band-type brake is to be with the clamp of friction skins to form by two, opens closure while stopping during elevator cage operation.Friction force between band-type brake dish on clamp and traction sheave is braking force.Elevator is in long-term use, and friction skin can wear and tear to some extent, carbonization, can reduce braking force.Also have, above-mentioned a series of cabin elevator action is all to carry out integrated control by the electric control system of cabin elevator.In long-time use, software control part also can exist data perturbation, the situation such as out of control to occur.In foregoing three kinds of situations, as long as there is one, just easily cause elevator when flat bed stops, to slip car (slipping) phenomenon, gently cause passenger flurried, serious also can cause security of the lives and property accident.

In existing elevator standard, elevator design standard, all do not relate to the associated safety degree of protection requirement that relevant lift car slips.Therefore, in current most of elevator device on the market, all do not prevent the corresponding safeguard procedures that car slips, even if having and related to the safety method that prevents that car from slipping in fraction elevator device, but this measure is all also the mode by pure electrical control substantially to be realized, for example in each stop position of elevator hoistways, travel switch is installed, or by setting up coder, by coder, convert car lifting straight-line displacement to electric control system that electric signal sends to cabin elevator, by electric control system, judge whether car occurs slipping, thereby drive wire holder or/and the lift car emergency braking apparatus such as safety tongs are braked by force to operating car.But that mentions in above-mentioned prevents the pure electric control method that car slips, there is the technological deficiency of application poor stability in it.

Summary of the invention

The object of the invention is to provide in order to solve above-mentioned the deficiencies in the prior art the anti-slip moving method of flat bed of the cabin elevator that a kind of operating troubles rate is low.

To achieve these goals, the anti-slip moving method of flat bed of a kind of cabin elevator that the present invention is designed, it has adopted rope sheave and/or rope sheave ejector and the lift car emergency braking apparatus in elevator governor, wherein rope sheave and/or rope sheave ejector and lift car synchronization action, when lift car enters flat bed and stops, by the physics path increment of rope sheave and/or rope sheave ejector Real-Time Monitoring lift car, when lift car slips phenomenon, there is synchronous rotation in above-mentioned rope sheave and/or rope sheave ejector, by this swing offset amount, control lift car emergency braking apparatus and carry out emergency braking, and also can further disconnect elevator safety operation loop.
