Chinese patent: number of patent application 20,122,061,282 1. 7, notification number CN 202967431 U, date of publication 2013.06.05, this utility model discloses a kind of motorized pulleys with non-return device, comprise motor reducer, coupler, main shaft and cylinder, also comprise a non-return device, described non-return device is enclosed within on main shaft, between coupler and cylinder.The motorized pulleys of the utility model band non-return device can complete material safe transfer, can not cause motorized pulleys reversion, skid and the accident of motor damage, be conducive to guarantee safe production.
Chinese patent: number of patent application 201220379898.4, notification number CN 202657608 U, day for announcing 2013.01.09, this relates to a kind of motorized pulleys that are applied to fixed type and movable belt conveyor, i.e. frequency conversion motorized pulleys.It comprises electrical motor and retarder in cylinder, and electrical motor is connected with frequency converter.Frequency conversion motorized pulleys are to increase frequency conversion function on the basis of original motorized pulleys.Realize energy-conservation, high-precision permanent torque control and high-speed driving.Realize motorized pulleys in the time of specified output torque, can realize infinite speed variation.The electronic cylinder constant moment of torsion of frequency conversion.Frequency conversion motorized pulleys can expand the application scenario of motorized pulleys, can reduce user's operating cost, improve resource utilization, the energy-conservation requirement that meets nation-building conservation-minded society.
Although comprehensive above-mentioned patent has solved more present technical matterss, also exists function singleness, problem that can not automation.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of functional effect is more, the motorized pulleys of automatic alarm anti-reverse that again can automation.
To achieve these goals, the present invention has adopted following technical scheme:
Motorized pulleys for automatic alarm anti-reverse, comprise electrical motor, reductor, coupler, main shaft and cylinder and non-return device, wherein: also include arrangement of clutch, induction module, frequency converter, control module, Liquid Crystal Display and warning device; Described electrical motor, reductor, arrangement of clutch, coupler, reversing gear and motorized pulleys are connected and fixed successively; Described electrical motor is connected with frequency converter, control module and induction module; Described non-return device is arranged on main shaft; Described warning device is connected with induction installation; Described Liquid Crystal Display is connected with induction module.
Above-described non-return device comprises the ratchet that relative main shaft is fixing, and is wrapped in the overcoat fixing with respect to cylinder of ratchet outside; The excircle of described ratchet is distributed with some ratchets, between adjacent ratchet, is provided with ball, the ball cooperation that contacts with the inwall of overcoat, and described ratchet is trapezoidal shape.
Above-described warning device is combined aural and visual alarm.
Above-described control module is connected with induction module and frequency converter respectively.
Above-described control module is microprocessor.
Above-described power-transfer clutch is self-acting clutch, self-acting clutch link control module.
Above-described induction module comprises voltage sensor and current inductor.
Above-described electrical motor is servomotor torque constant.
Principle of work: electrical motor, reductor, coupler, main shaft and cylinder, non-return device, arrangement of clutch, induction module, frequency converter, warning device and control module; Described electrical motor, reductor, arrangement of clutch, coupler, motorized pulleys are connected and fixed successively; Described electrical motor is connected with frequency converter, control module and induction module; Liquid Crystal Display is connected with induction module; When work, when cylinder rotates, induction module is monitored the service condition of servomotor in real time, and the service condition of servomotor is reflected to control module, when servomotor occurs when abnormal that control module can judge accordingly, thereby carry out frequency conversion and realize and control servomotor as controlled frequency converter; In the time that cylinder occurs overload or reverses, control module is just controlled self-acting clutch and is automatically separated protection servomotor and reductor; When servomotor work occurs when abnormal, inductor sends signalling alarm equipment work to start to report to the police, and Liquid Crystal Display shows abnormal concrete data.Be arranged on the reversing gear on main shaft, the reason that when forward, forward is installed, can unresistedly together rotate with main shaft, when load strengthens suddenly or runs into the reasons such as power failure, suddenly while giving an opposing torque of cylinder, because the special design structure of non-return device, stop the inverse motion of electric rolling.
