Abstract
The invention discloses a lift control device of an electric clothing storage cradle. The device is safe and reliable to use and can not easily damage the motor. The device comprises a bracket, a motor and a controller, wherein a tilting plate is hinged with one side of the bracket; one end of the tilting plate is heavier than the other end thereof; the heavier end is provided with a mercury switch; the lighter end is tied with a lifting rope; a permanent magnet is tied below the lifting rope; and the mercury switch is electrically connected with a cradle ascending control circuit on the controller. Since the motor is only controlled by the switch, heavy current can not occur, the coil can not be damaged by heating, and the motor has longer service life. Meanwhile, the abrasion between a motor reducing mechanism and the lifting rope is greatly reduced.
Description
Technical field
The present invention relates to the apparatus for controlling of lifting of a kind of control setup, particularly a kind of electric clothing storage cradle.
Background technology
Deposit the device of clothing when at present the colliery publilc baths all adopts clothing storage cradle to have a bath as the miner basically, clothing storage cradle is extensively promoted the use of with its clean hygiene, neat appearance and plurality of advantages such as antitheft.Adopt the clothing storage cradle of electric up-down now, its mode mainly is by controlling the break-make of two independent loop power supplys, realizing the lifting operation of clothing storage cradle.When rising clothing storage cradle, the concrete scheme that adopts is now, when hanging basket soon rises when putting in place, at first enter in the groined type framework that is lifted under the top ceiling, hanging basket continues to rise under the directional tagging of framework, hanging basket is limited after arriving tip position can not rise again, but electrical motor still works on, and the suffered resistance of electrical motor this moment heightens, and its working current sharply increases, shut down when control circuit detects big current signal, hanging basket rising this moment control process finishes.This control principle is when utilizing the electrical motor working current sharply to rise, and the big electric current of formation comes the control motor to shut down as control signal.This mode has strengthened the load of electrical motor, shortened the service life of electrical motor, easily cause motor winding heating accident on fire to take place when serious, the wearing and tearing between motor deceleration mechanism and the stay cord have also been strengthened simultaneously, cause potential safety hazard, now have because of stay cord and broken, hanging basket falls down pounds the incident generation of hurting sb.'s feelings.
Summary of the invention
The objective of the invention is to overcome the defective that above-mentioned prior art exists, a kind of apparatus for controlling of lifting of electric clothing storage cradle is provided, this device uses safe and reliable and not fragile electrical motor.
The technical solution adopted in the present invention is: comprise support, electrical motor and controller; Seesaw and support one side are hinged, and the weight ratio other end of seesaw one end is heavy, and a heavier end is equipped with mercury switch, and there is lifting rope in lighter end system, and there is a permanent magnet in lifting rope below system, and mercury switch is electrically connected with hanging basket rising control loop on the controller.
The bottom, hinged place is provided with limiting stopper.
Adopt seesaw and support one side hinged among the present invention, an end heavier on the seesaw is equipped with mercury switch, there is lifting rope in other end system, there is the structure of a permanent magnet in lifting rope below system, when the hanging basket rising soon puts in place, permanent magnet is adsorbed onto on the iron framework on hanging basket top, the seesaw lack of equilibrium, seesaw is equipped with an end backspin of mercury switch by from recoiling the hinge rotation, and mercury switch deflects, mercury in the mercury switch is connected with contact open, thereby disconnected the power supply of electrical motor, electrical motor is out of service, and hanging basket just in time rose and put in place this moment.Because electrical motor is controlled by switch only, the situation of big electric current can not occur, be difficult for taking place the phenomenon that coil heating damages, electrical motor longer service life.Simultaneously, the wearing and tearing between motor deceleration mechanism and the stay cord also reduce greatly.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the right elevation of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail, but does not constitute any limitation of the invention.Illustrated in figures 1 and 2, the present invention includes support 6, electrical motor 10 and controller 11.Two control loops that work alone are housed in the controller 11, and one is the rising control loop, and another is the decline control loop.Seesaw 1 is hinged with the side plate of support 6, and seesaw 1 two ends are different to the distance of hinge, thereby makes the weight ratio other end of seesaw 1 one ends heavy.A heavier end is equipped with mercury switch 8, and there is lifting rope 2 in other end system, and there is a permanent magnet 3 in lifting rope 2 belows system.Mercury switch 8 is electrically connected with hanging basket 4 rising control loops on the controller 11.Seesaw 1 is fixed with limiting stopper 7 with the below of the side plate hinged place of support 6, with the rotation that prevents that seesaw 1 is excessive.Before hanging basket 4 rose, it is sagging that seesaw 1 hangs an end of permanent magnet 3, and at this moment, mercury switch 8 is in electric on-state.When rising hanging basket 4, the user presses the rising source switch, connect the power supply of rising control loop, electrical motor 10 starts, electrical motor 10 drives reel 9 rotations, and reel 9 scrolling stay cords 5 rise hanging basket 4, when the iron framework in the top of hanging basket 4 touches permanent magnet 3, permanent magnet 3 is adsorbed onto hanging basket 4 tops, the lower end of lifting rope 2 is no longer stressed, and seesaw 1 loses original state of equilibrium, and seesaw 1 is by rotating from recoiling hinge, seesaw 1 backspin of mercury switch 8 one ends is housed, mercury switch 8 deflects, and the mercury in the mercury switch 8 is connected with contact open, thereby has disconnected the power supply of electrical motor 10, electrical motor 10 is out of service, and hanging basket 4 just in time rose and put in place this moment.When hanging basket 4 descended, the user pressed the decline source switch, connected the power supply of decline control loop, electrical motor 10 is started working, and hanging basket 4 descends and breaks away from permanent magnet 3, and arriving needs to press the decline source switch once more behind the height, cut off electrical motor 10 power supplys, hanging basket 4 stops to descend.Decline control loop in the controller 11 is a prior art, does not repeat them here.Mercury switch 8 is connected in series to mercury switch 8 in the rising control loop of controller for existing commercially available prod among the present invention, realizes switching on and off the purpose of electrical motor 10 power supplys.
