Abstract
The utility model discloses a kind of electrical automatic control equipment for building hoist braking, comprise lifter motor control circuit, fault detect control circuit and delays time to control control circuit, the control input end of described lifter motor control circuit is connected with the control output end of described fault detect control circuit, the detection signal input of described fault detect control circuit is connected with described lifter motor power supply, and control output end and the described fault detect control circuit of described delay control circuit are connected in parallel.Compared with prior art, motor can be passed through time relay slow releasing when motor power power-off by the utility model, thus effectively prevent the danger caused that has a power failure suddenly or break down, employing electronic component forms, with low cost, the cost of machine rebuilding can be reduced, there is the value applied.
Description
Technical field
The utility model relates to a kind of electric automatic control equipment, particularly relates to a kind of electrical automatic control equipment for building hoist braking.
Background technology
It is electrically the general designation of the subjects such as the production of electric energy, transmission, distribution, use and electrician's equipment manufacturing or engineering field.Be with electric energy, electric equipment and electrical technology for a science of restriceted envelope and environment is created, maintains and improved to means, contain the conversion of electric energy, utilization and research three aspect, comprise basic theory, application technology, facilities and equipment etc.The lift power supply be applied in prior art in building trade is all Non-follow control usually, but run into when having a power failure suddenly or occur other faults, lift will cause decline automatically out of hand, easily cause danger, though there is additive method to prevent, cost is high, not easily promotes, therefore, need to improve in the control of motor.
Utility model content
The purpose of this utility model is just to provide a kind of electrical automatic control equipment for building hoist braking to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises lifter motor control circuit, fault detect control circuit and delays time to control control circuit, the control input end of described lifter motor control circuit is connected with the control output end of described fault detect control circuit, the detection signal input of described fault detect control circuit is connected with described lifter motor power supply, and control output end and the described fault detect control circuit of described delay control circuit are connected in parallel.
Further, described fault detect control circuit is made up of four contactors, and described lifting motor control circuit is made up of the control switch of contactor, and described delay control circuit is made up of the quick-fried lock of the time relay, diode, potentiometer and electromagnetism.
The beneficial effects of the utility model are:
The utility model is a kind of electrical automatic control equipment for building hoist braking, compared with prior art, motor can be passed through time relay slow releasing when motor power power-off by the utility model, thus effectively prevent the danger caused that has a power failure suddenly or break down, employing electronic component forms, with low cost, the cost of machine rebuilding can be reduced, there is the value applied.
Accompanying drawing explanation
Fig. 1 is circuit structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises lifter motor control circuit 1, fault detect control circuit 2 and delays time to control control circuit 3, the control input end of lifter motor control circuit 1 is connected with the control output end of fault detect control circuit 2, the detection signal input of fault detect control circuit 2 is connected with lifter motor power supply, and control output end and the fault detect control circuit 2 of delay control circuit 3 are connected in parallel.
Further, fault detect control circuit 2 is made up of four contactors, lifting motor control circuit 1 is made up of the control switch of contactor, and delay control circuit 3 is made up of the diode VD of time relay KT, model IN4007, the potentiometer R in 470 Europe and the quick-fried lock YA of electromagnetism.
Operation principle of the present utility model is as follows:
When one of contactor KM2-KM4 disconnects, time relay KT dead electricity, its timing closing normally opened contact disconnects through certain time-delay (about 0. 5s), and contactor KM1 dead electricity discharges, and its normally opened contact disconnects, and electromagnetic brake YA dead electricity brake motor, does not make goods fall.The effect of KT is, after unexpected power-off, motor speed can not decline immediately, should not brake immediately it at high speed, realizes the object of Braking mode.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
