Description
Technical field
The utility model relates to a kind of elevator single armed brake detecting device, belongs to elevator and manufactures field.
Background technology
Elevator machine brake is its very important safety component.Once drg can not well work, that will be a very serious safety problem.
Current most of elevator producer is when designing, just consider whether detect drg enough normally opens or close, a kind of elevator brake Performance Detection experimental engine disclosed in patent No. CN104034520, when using this experimental engine, can test out elevator brake design parameter freely, accurately.But this experimental engine only can be tested before drg is installed, and cannot detect the drg in use, the elevator basic brakeless device measuring ability of even some producer design.
But only detection drg is opened or the closed potential safety hazard that whether normally also can there is certain probability, the drg abnormality detection system of elevator and method disclosed in patent No. CN102344066, by monitoring that the temperature of drg monitors brake operation with the suitable benchmark corresponding with the temperature characterisitic of drg.But drg is changed the mill lock operating mode caused after long-term work by gap, can not be detected by the open and close of drg secondary contact, also directly cannot be embodied by the operating temperature of drg, the reduction of brake braking force can be caused in the course of time, even directly brakeless power.
Utility model content
The utility model, for solving prior art problem, provides a kind of elevator single armed brake detecting device at any time elevator brake being carried out to braking forces measuring.
The technical solution of the utility model is: a kind of elevator single armed brake detecting device, comprise directly to be connected with drg and can control separately described brake operation independent current source, be serially connected with the circuit breaker in elevator safety loop and be arranged at the impulse singla device on traction sheave; Described independent current source, described circuit breaker are all connected with described impulse singla device and are controlled by same controller, and during detection, described controller controls described independent current source, described circuit breaker and described impulse singla device and to work and from described impulse singla device received signal simultaneously.
As preferably, described controller connects and has controlled indicating device, and described indicating device comprises the braking performance test indicating device that is used to indicate brake status and is used to indicate the state indicating device whether described controller is in detected state.
As preferably, described controller connects and controlledly has a timer device; Described timer device comprises two kinds of definition statuses, is respectively the described controller of control and enters the startup timing of detected state and control the continuity timing of described controller detected state duration.
As preferably, described controller is connected with towing machine and can detects towing machine mode of operation.
The utility model is a set of independently on-line measuring device, in the machine room that can be installed in any traction elevator or rack, for regularly carrying out on-line checkingi to drg.
In sum, the utility model has the following advantages:
1, regularly on-line checkingi is carried out to drg, do not need to disassemble, be convenient to implement;
2, ensure brake operation validity, improve safety.
Accompanying drawing explanation
Fig. 1 is the utility model principle schematic.
Detailed description of the invention
With embodiment, the utility model is described in further detail below.
Embodiment one:
A kind of elevator single armed brake detecting device, comprise directly to be connected with drg and can separately control brake work independent current source, be serially connected with the circuit breaker in elevator safety loop and be arranged at the impulse singla device on traction sheave; Independent current source, circuit breaker are all connected with impulse singla device and are controlled by same controller, and controller is connected with towing machine and can detects towing machine mode of operation.Detect Time Controller to control independent current source, circuit breaker and impulse singla device and to work and from impulse singla device received signal simultaneously.
Controller connects and has controlled indicating device, and indicating device comprises the braking performance test indicating device that is used to indicate brake status and is used to indicate the state indicating device whether controller is in detected state.
Controller connects and controlledly has a timer device; Timer device comprises two kinds of definition statuses, is respectively control controller and enters the startup timing of detected state and control the continuity timing of controller detected state duration.
During work, the controller of this detecting device detects the mode of operation of towing machine, by detecting towing machine, whether action judges whether elevator is in running state, when without operation, point detection time of the startup timing specification that this detecting device pre-sets according to timer device detects, also namely elevator detects beginning automatically without after operation certain hour, and the certain hour section that also can be set by startup timing specification, as intraday particular point in time detects.After detecting pattern starts, this detecting device is by the safety return circuit first by circuit breaker trip elevator, the safety return circuit of elevator controls the power supply of whole elevator, so that elevator cuts off whole power supplies of elevator when there is safety failure, avoiding the generation of further accident, is one of each elevator important component; Therefore, after the safety return circuit of circuit breaker trip elevator, whole elevator is in electroless state.Then, the state indicating device work of this detecting device, conventional state indicating device is the LED of two different colours, indicate normal operating condition and detected state respectively, now " normally " LED is extinguished, and " detection " LED is lighted, indicate this elevator to enter detected state, cannot use.Independent current source is for a set of independent of the electric supply installation of elevator rack, starts under control of the controller after the safety return circuit of elevator is cut-off, needs the drg detected to power separately to elevator; After state indicating device normally indicates, controller controls independent current source as required respectively and carries out power transmission to 2 drgs, and need to detect needs difference certain time under the continuity fixed-time control of timer device, meanwhile, controller control wave device starts.Impulse singla device is installed on traction sheave, by and the only control of controlled device and energy supply, the effect of impulse singla device is the state detecting traction sheave, the output pulse signal when traction sheave has rotation, and traction sheave rotating speed is faster, and pulse signal frequency is higher.Braking force as drg is normal, then traction sheave can not be driven under the braking of drg to rotate without the lift car of powering and counterweight, i.e. now impulse singla device no-output; Braking force as drg is inadequate, then can produce under the braking of drg without the lift car of power supply and counterweight and slip car, traction sheave can be driven to rotate by wirerope, now impulse singla device has pulse to export, after controller receives impulse singla, instruction is sent, display brake troubles by braking performance test indicating device.
