Detailed description of the invention
Applicant will elaborate below by way of example by reference to the accompanying drawings, but be not all the restriction to technical solution of the present invention to the description of embodiment, any conceive according to the present invention done be only pro forma but not substantial equivalent transformation and all should be considered as technical scheme category of the present invention.
embodiment 1
Refer to Fig. 1, First Line coil assembly 4, retarding spring 5 that elevator brake of the present invention comprises static iron core 1, dynamic iron core 2, friction component 3 and is located in static iron core 1, described static iron core 1 and friction component 3 are placed in the both sides of dynamic iron core 2 respectively, and friction component 3 and dynamic iron core 2 are solidly installed.Described friction component 3 is installed on the brake wheel 7 on axle drive shaft 6 for stop, when drg is in closed condition, First Line coil assembly 4 is in off-position, friction component 3 utilizes the spring force pressure of retarding spring 5 to lean against on brake wheel 7 and produces friction force with brake wheel 7, plays the effect of stop brake wheel 7.
When elevator is in halted state, to make elevator restart, drg is so needed to discharge brake wheel 7, then to brake guaranties, electric current is flow through in First Line coil assembly 4, between static iron core 1, dynamic iron core 2 and both working clearance A, form magnetic loop, produce electromagnetic force, overcome the spring force of retarding spring 5, static iron core 1 and dynamic iron core 2 attract each other, dynamic iron core 2 is close to First Line coil assembly 4 direction, and dynamic iron core 2 departs from brake wheel 7 with friction component 3, and brake wheel 7 realizes free rotation.
Refer to Fig. 2, when the figure shows brake guaranties, flow through the time dependent wave character figure of electric current (also claiming coil current) in First Line coil assembly 4, with the moment be energized to First Line coil assembly 4 for starting point 0, in 0 ~ ta time period, coil current increases, and electromagnetic force is also along with increase.At ta time point, electromagnetic force is equal with the spring force of retarding spring 5, then dynamic iron core 2 starts to move to static iron core 1 direction, namely close to First Line coil assembly 4.Dynamic iron core 2 setting in motion can produce motion counter electromotive force, the speed drop that motion counter electromotive force makes coil current increase.In ta ~ tb time period, the kinematic velocity of dynamic iron core 2 is very little, and motion counter electromotive force is very little, and its ability hindering coil current to increase is very little, so coil current is still increasing but having slowed of increasing.After b point, the kinematic velocity of dynamic iron core 2 becomes large, the effect of motion counter electromotive force starts significantly, force electric current to decline, until static iron core 1 and dynamic iron core 2 adhesive completely, this pickup time, point was tc, dynamic iron core 2 stop motion, motion counter electromotive force disappears, and coil current stops declining, and rises by new exponential law according to applied voltage.If detecting device detects that electric current is by waveform changing features in Fig. 2, has occurred minimal value current i c, then static iron core 1 and dynamic iron core 2 adhesive of drg are described, drg implements opening action.
When elevator is in normal operating condition, to make elevator out of service, so need braking of brake brake wheel 7, then need drg power-off, First Line coil assembly 4 after power is turned off, electromagnetic force is lost between static iron core 1 and dynamic iron core 2, dynamic iron core 2 away from static iron core 1, namely away from First Line coil assembly 4, is pressed against on brake wheel 7 with friction component 3 and also and between brake wheel 7 produces friction brake force under the effect of retarding spring 5, thus stop brake wheel 7, elevator is out of service.
Refer to Fig. 3, when the figure shows drg power-off, the time dependent wave character figure of coil current, with the moment to First Line coil assembly 4 power-off for starting point 0, in 0 ~ td time period, coil current reduces, and electromagnetic force is also along with reduction.At td time point, electromagnetic force is equal with the spring force of retarding spring 5, then dynamic iron core 2 starts away from static iron core 1, namely away from First Line coil assembly 4.Dynamic iron core 2 setting in motion can produce motion counter electromotive force, the speed drop that motion counter electromotive force makes electric current reduce.In td ~ te time period, the kinematic velocity of dynamic iron core 2 is very little, and motion counter electromotive force is very little, and its ability hindering electric current to reduce is very little, so coil current is still reducing but having slowed of reducing.After e point, the kinematic velocity of dynamic iron core 2 becomes large, the effect of motion counter electromotive force starts significantly, electric current is forced to increase, until when moving iron core 2 stop motion when friction component 3 presses against brake wheel 7, the time point of this dynamic iron core 2 stop motion is tf, dynamic iron core 2 stop motion, motion counter electromotive force disappears, and coil current stops increasing, and is 0V and reduces by new exponential law according to voltage after power-off.If detecting device detects that electric current is by waveform changing features in Fig. 3, has occurred maximum value current i f, then illustrate that the static iron core 1 of drg is separated with dynamic iron core 2, friction component 3 has been pressed against on brake wheel 7, and drg implements closing movement.
The method of inspection of the drg operating state that the present embodiment relates to is that when utilizing the energising of above-mentioned brake coil or power-off, whether the time dependent wave character of coil current correctly opens or closes to detect drg, concrete method is: elevator run start or at the end of, the current data in First Line coil assembly 4 is flow through when gathering brake guaranties or power-off, according to the change of sample rate current, whether there is the wave character shown in Fig. 2 or Fig. 3 and judge drg whether regular event, and accordingly result is flowed to apparatus for controlling elevator.
