Embodiment

Below in conjunction with Figure of description embodiment of the present utility model is described in further detail.

The utility model proposes a kind of staircase additional brake test macro, comprise power module, limit switch, the tested additional brake coil of control whether switch on the switching controls module of conducting, to the conducting of the tested additional brake coil electricity of switching controls module controls, second counter and the output unit that send first counter that the number of times of control command counts, the closed number of times of limit switch is counted; Power module links to each other with tested additional brake coil through the switching controls module, and first counter is connected with the switching controls module; Limit switch links to each other, is arranged on the position corresponding with tested additional brake adhesive action with power module, the closure of the adhesive action control limit switch of tested additional brake, and limit switch links to each other with second counter simultaneously; First counter links to each other with output unit respectively with second counter.

Described power module is that tested additional brake coil is powered through the switching controls module, therebetween, by the conducting of whether switching on of the tested additional brake coil of switching controls module controls, first counter that is connected with the switching controls module is counted the conducting of the tested additional brake coil electricity of switching controls module controls, the number of times that sends control command; The conducting of described tested additional brake coil electricity, be that tested additional brake is started working, because limit switch links to each other, is arranged on the position corresponding with tested additional brake adhesive action with power module, so closure of the adhesive of tested additional brake action control limit switch, second counter that links to each other with limit switch is counted the closed number of times of limit switch, namely the adhesive number of times of tested additional brake is counted.

The staircase additional brake test system structure of the utility model design is simple, be easy to realize that not only low cost of manufacture, and test process and test result are intuitively clear, be convenient to the staff tested additional brake is carried out test job.

Described power module links to each other with tested additional brake coil through contactor, contactor is controlled the conducting of whether switching on of tested additional brake coil, wherein, the break-make of contactor coil is controlled by coupled PLC controller, in the practical application, the PLC controller can be set constantly send control signal to contactor in appointed interval the time, the break-make of control contactor coil, and then realize that the tested additional brake of control carries out work automatically, improve testing efficiency.

In the staircase additional brake test macro of the utility model design, adopt the PLC controller to be used for the work of whether switching on of the tested additional brake of control, saved manual operation too much in the test process, improved the efficient of test job.

As a kind of optimal technical scheme of the present utility model: described power module comprises external power supply, isolating switch and transformer, external power supply links to each other with described switching controls module through isolating switch, transformer successively, wherein, isolating switch can conveniently cut off and conducting the power supply of external power supply.

In the staircase additional brake test macro of the utility model design, at power module, the mode that employing isolating switch and transformer cooperate can effectively play protective effect to tested additional brake for the test job of detent provides power supply.

The staircase additional brake test macro of the utility model design adopts tested additional brake test bracket that tested additional brake is fixed in test process, is convenient to the carrying out of test job.

The staircase additional brake test macro of the utility model design is in the middle of actual application, external power supply is through isolating switch, transformer, contactor, be tested additional brake coil power supply, the PLC controller is connected with contactor, wherein, isolating switch is realized the power supply of external power supply is cut off and conducting, the PLC controller is used for the break-make of control contactor coil, and then control tested additional brake work, namely control tested additional brake adhesive, in the application, the PLC controller can be set constantly send control signal to contactor in appointed interval the time, the break-make of control contactor coil, and then realize that the tested additional brake of control carries out work automatically; The PLC controller whenever sends control signal one time, the conducting of control contactor coil once, and then make the conducting of tested additional brake coil once, because the switching controls module comprises the PLC controller of contactor and control contactor coil break-make, first counter is just counted the conducting of the tested additional brake coil electricity of switching controls module controls, the number of times that sends control command, and the conducting of the tested additional brake coil electricity of switching controls module controls, the number of times that sends control command have namely represented the work number of times of controlling tested additional brake; The conducting of tested additional brake coil makes tested additional brake carry out work, tested additional brake adhesive, because the closure of the adhesive of tested additional brake action control limit switch, the every closure of limit switch once, second counter is just counted the closed number of times of limit switch, namely the adhesive number of times of tested additional brake is counted; When the PLC controller quits work, i.e. test job at tested additional brake finishes, the count value of the count value of first counter and second counter is exported by output unit, compare the count value of first counter and second counter this moment, when numerical value is inconsistent, can judge that there is fault in tested additional brake; When comparing the numerical value unanimity, judge that then tested additional brake is normal.
