Description
Technical field
The utility model relates to a kind of elevator up-running over-speed protection demo plant, belongs to elevator and manufactures field.
Background technology
The elevator of vertical operation is just being applied in middle and high layer building more and more widely.Due to the reliability of vertical lift and the life security of passenger closely bound up, therefore vertical lift is often provided with a large amount of safety detection and safety convenience instrument.These safety devices go to toward all can through close inspection dispatching from the factory, but after elevator uses site assembly completely, lack corresponding checking, therefore the elevator infringement to elevator components of transporting after finalization of the manufacture, may cause in installation process, especially the infringement of safety component, is often not easily discovered in conventional operation.
Utility model content
The utility model, for solving prior art problem, provides a kind of device for detecting elevator safety loop and the protection device for over-speed ascending reliability installed.
The technical solution of the utility model is: a kind of elevator up-running over-speed protection demo plant, comprise a set of electric power system be independently electrically connected with the drg of elevator, at least two separate electric connecting elements for controlling the break-make between described electric power system and drg, the actuating mechanism for controlling described electric connecting element work of being powered by elevator safety loop; The propulsion source of described actuating mechanism and elevator is connected, and the car of cut-out propulsion source to elevator provides power when described actuating mechanism starts.
As preferably, described electric connecting element is the contact of contactless switch; Described actuating mechanism comprises the coil matched with described contact, for controlling the starting switch of break-make between described elevator safety loop and described coil.
As preferably, described electric connecting element is provided with two, is connected to the two poles of the earth of described electric power system.
As preferably, described starting switch comprises the hand push buttons of at least two series connection mutually.
As preferably, described elevator safety loop comprises the load sensor be arranged at bottom lift car.
As preferably, described load sensor is pressure inductor.
As preferably, described elevator safety loop comprises the layer door detector for detecting each flat bed door switch situation.
The utility model is after elevator installation in principle, by cutting off propulsion source to car, makes car under the effect of counterweight, slip car, when car slip car reach certain speed time, the safety return circuit of elevator detects elevator overspeed, has an effect, make brake, stop car.
Because traditional sure brake will stop car when loss signal, therefore the utility model increases a set of independently electric supply installation newly and powers to drg to drg, for ensureing the safety of operator, contactless switch is adopted to be isolated by the actuating mechanism of electric supply installation with operation, actuating mechanism is powered by the safety return circuit of elevator, therefore the safety return circuit when elevator is only had, namely when the safety checker that elevator is all normally works, actuating mechanism just has electricity, after operating personal presses the button, contactless switch is connected, electric supply installation is communicated with drg, the engine installation of elevator cuts off the propulsion source of car simultaneously, car starts to slip car, when reaching dangerous speed, as drg is intact, then car can be stopped and be stopped, also do not stopped as car after at the bottom of counterweight pier and stopped, then brake troubles.
The utility model adopts two action buttons of mutually connecting, and must press, this demo plant just can work simultaneously, avoids maloperation and makes this demo plant accidental activation.Arranging in the safety return circuit of elevator for detecting flat bed door and car load, ensure that elevator all flat bed Men Jun when verifying are in closed condition, and unmanned in car, prevent accident.Adopt between electric supply installation and drg and controlled by two-way, reduce the possibility that contact adhesion lost efficacy, with the safety and reliability of warranty test process.
In sum, the utility model has the following advantages:
1, extras are not needed, and can at any time for detecting the validity of elevator brake system;
2, also can detect elevator safety loop simultaneously have reliability, feature richness.

Detailed description of the invention
With embodiment, the utility model is described in further detail below.
Embodiment one:
A kind of elevator up-running over-speed protection demo plant, comprise a set of electric power system be independently electrically connected with the drg 3 of elevator, at least two separate electric connecting elements for controlling the break-make between electric power system and drg 3, the actuating mechanism for controlling electric connecting element work of being powered by elevator safety loop 2; The propulsion source of actuating mechanism and elevator is connected, and the car of cut-out propulsion source to elevator provides power when actuating mechanism starts.Elevator safety loop 2 comprises and is arranged at the load sensor bottom lift car and the layer door detector for detecting each flat bed door switch situation, and load sensor is pressure inductor.Electric connecting element is the contact of contactless switch 1; Actuating mechanism comprises the coil matched with contact, for controlling the starting switch of break-make between elevator safety loop 2 and coil.Starting switch comprises at least two hand push buttons 4 of mutually connecting.
During the work of this demo plant, first empty car, and close all flat bed doors to ensure safety.Then press two hand push buttons 4 simultaneously, safety return circuit 2 as elevator is intact, the now coil electricity of two contactless switchs 1, the contact adhesive of contactless switch 1, voltage transformer in electric power system is to the coil power supply of drg 3, cut off the propulsion source of car simultaneously, car and counterweight slip car because of the overbalance of weight, car accelerates up, counterweight is accelerated descending, when car go upward to exceed safety speed time, the safety return circuit 2 of elevator detects danger, cutting power supply, the now coil blackout of contactless switch 1, contact separation, the coil blackout of drg 3, drg 3 pairs of cars realize stopping stopping.Do not stop yet as car after at the bottom of counterweight pier and stop, then drg 3 fault, needs repairing.
The utility model increases a set of independently electric supply installation 5 pairs of drgs 3 newly and powers, for ensureing the safety of operator, contactless switch 1 is adopted to be isolated by the actuating mechanism of electric supply installation 5 with operation, actuating mechanism is powered by the safety return circuit 2 of elevator, therefore the safety return circuit 2 when elevator is only had, namely when the safety checker that elevator is all normally works, actuating mechanism just has electricity, after operating personal presses the button 4, contactless switch 1 is connected, electric supply installation 5 is communicated with drg 3, the engine installation of elevator cuts off the propulsion source of car simultaneously, car starts to slip car, when reaching dangerous speed, as intact in drg 3, then car can be stopped and be stopped, also do not stopped as car after at the bottom of counterweight pier and stopped, then drg 3 fault.
The utility model adopts two action buttons 4 of mutually connecting, and must press, this demo plant just can work simultaneously, avoids maloperation and makes this demo plant accidental activation.Arranging in the safety return circuit 2 of elevator for detecting flat bed door and car load, ensure that elevator all flat bed Men Jun when verifying are in closed condition, and unmanned in car, prevent accident.Adopt between electric supply installation 5 and drg 3 and controlled by two-way, reduce the possibility that contact adhesion lost efficacy, with the safety and reliability of warranty test process.
