The protective system for the electromagnetic contracting brake has the advantage that the joint state of the electromagnetic contracting brake can be fed back to the electrical control device so as to ensure that the electric motor can be started to run in the open state of the electromagnetic contracting brake, therefore, the safety and the reliability of equipment are greatly enhanced.
Description
Technical field
The utility model relates to the electromagnetic brake that is used for braking motor, relates in particular to a kind of electromagnetic brake protection system that electromagnetic brake is protected.
Background technology
Electromagnetic brake is industrial service braking equipment, and electromagnetic brake often is installed in the non-load side of motor, and Fig. 1 is the typical control principle figure of motor and band-type brake.When equipment need turn round, electrical control gear 100 sent opening signal to electromagnetic brake 200 earlier, and electromagnetic brake 200 is opened, and the motor main circuit switch is closed on 301, motor 300 entrys into service; When equipment need be shut down, motor main circuit switch 301 is disconnected, motor 300 shuts down, and sends shutdown signal to electromagnetic brake 200 again, and electromagnetic brake 200 is closed.
Fig. 2 shows the basic structure of electromagnetic brake, mainly by fixed mount 201, and action link rod 202, brake wheel 203 and brake shoe 204 constitute.Do not have a deciliter status signal to feed back to electrical control gear 100 on the present employed electromagnetic brake, owing to reasons such as the electromagnetic brake actuating mechanism are bad, motor turns round under the situation that band-type brake is not opened, and can burn brake shoe 204 until damaging band-type brake 200.
The utility model content
Technical problem to be solved in the utility model provides a kind ofly can give electrical control gear with electromagnetic brake deciliter state feedback and guarantee that motor opens the electromagnetic brake protection system that starts running under the situation at electromagnetic brake, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electromagnetic brake protection system; comprise electrical control gear; the motor main circuit switch and the electromagnetic brake that are electrically connected with electrical control gear respectively; it is characterized in that: band-type brake deciliter condition checkout gear is installed on the described electromagnetic brake, also is electrically connected a relay J 2 between this band-type brake deciliter condition checkout gear and the electrical control gear.
In further improvement of the utility model, also be electrically connected a relay on the electrical control gear, this relay J 1 is used to control electrical control gear and sends the electromagnetic brake opening signal.
Described band-type brake deciliter condition checkout gear is by constituting near switch and catch, is electrically connected on the described fixed mount that is installed in electromagnetic brake near switch and with relay J 2, and catch is installed on the action link rod of electromagnetic brake.
Described is induction near switch near switch.
Adopt technique scheme, by band-type brake deciliter condition checkout gear being installed on the electromagnetic brake and between band-type brake deciliter condition checkout gear and electrical control gear, being electrically connected a relay J 2, electrical control gear is after electromagnetic brake sends opening signal, after if electromagnetic brake is opened, band-type brake deciliter condition checkout gear can obtain the opening signal of electromagnetic brake, and this opening signal fed back to relay J 2, relay J 2 closed control electrical control gear control motor main circuit switch closures, the starter motor running, if because the electromagnetic brake actuating mechanism is bad, electromagnetic brake fails to open, then band-type brake deciliter condition checkout gear can not get the opening signal of electromagnetic brake, relay J 2 can not be closed, thereby can not make electrical control gear control motor main circuit switch closure make the electric motor starting running, start the danger that running causes damaging electromagnetic brake under the situation thereby avoided motor not open at electromagnetic brake.
Therefore, electromagnetic brake protection system of the present utility model has can give electrical control gear with electromagnetic brake deciliter state feedback and guarantee that motor opens the advantage that starts running under the situation at electromagnetic brake, and the fail safe of equipment and reliability are greatly enhanced.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is the electric machine control system schematic diagram;
Fig. 2 is the structural representation of electromagnetic brake;
Fig. 3 is the electric machine control system schematic diagram that comprises the electromagnetic brake protection system;
Fig. 4 is the structural representation that the electromagnetic brake of band-type brake deciliter condition checkout gear has been installed.
Embodiment
As shown in Figure 3, electromagnetic brake protection system in this electric machine control system comprises electrical control gear 100, electromagnetic brake 200,301, two relay J 1 of motor main circuit switch, J2, band-type brake deciliter condition checkout gear 400.Wherein, electromagnetic brake 200, motor main circuit switch 301 are electrically connected with electrical control gear 100 respectively, band-type brake deciliter condition checkout gear 400 is installed on the electromagnetic brake 200, between band-type brake deciliter condition checkout gear 400 and electrical control gear 100, be electrically connected relay J 2, in addition, relay device J1 also is electrically connected with electrical control gear 100.
As shown in Figure 4, band-type brake deciliter condition checkout gear 400 is by constituting near switch 401 and catch 402, wherein, select for use induction near switch near switch 401, be installed on the fixed mount 201 of electromagnetic brake 200 and and be electrically connected with relay J 2, catch 402 be installed in electromagnetic brake 200 action link rod 202 on, particularly, be installed in the crossover location place of fixed mount 201 and action link rod 202 near switch 401 and catch 402.
In conjunction with shown in Figure 3, the course of work of electromagnetic brake protection system of the present utility model is such: starter motor 300, at first make relay J 1 closure, control electrical control gear 100 is opened electromagnetic brake 200, if electromagnetic brake 200 is opened, action link rod 202 can move, catch 402 is motion and then, can touch near switch 401 when arriving the fully open position, make near switch 401 and produce opening signal, and this opening signal fed back to relay J 2, make relay J 2 closures, at this moment under relay J 1 and relay J 2 equal closed situations, will control the running of motor main circuit switch closure starter motor thereby control electrical control gear 100, owing to be to open the back starter motor fully at electromagnetic brake 200, shown in electric motor starting running can not cause the damage of electromagnetic brake 200; If electromagnetic brake 200 actuating mechanisms are bad, electromagnetic brake 200 fails to open, catch on the action link rod 202 also just can not touch near switch 201, naturally can not obtain opening signal near switch 201, and then relay J 2 just can be not closed yet, electrical control gear 100 just can closed motor main circuit circuit 301 yet, and motor 300 will be in halted state all the time, can not occur in the damage that starter motor running under the situation that electromagnetic brake 200 do not open causes electromagnetic brake 200.
Therefore, electromagnetic brake protection system of the present utility model has can give electrical control gear with electromagnetic brake deciliter state feedback and guarantee that motor opens the advantage that starts running under the situation at electromagnetic brake, and the fail safe of equipment and reliability are greatly enhanced.
