Description
Technical field
The utility model relates to construction implement field, is specifically related to a kind of novel elevating machine control system.
Background technology
Elevator is the platform of carrying people or goods lifting or the elevating gear equipment of semiclosed platform or device on passage vertically.Elevator i.e. safety but also there is the load-carrying capacity of super large and easy to maintenance and be widely used in the realm of building construction.Existing building hoist adopts the method directly started to control usually.When starting, rush of current is comparatively large, and moment torque is not enough, thus causes the cage of elevator to glide instantaneously, affect electrical machinery life, in addition, when stopping, when electrical motor and construction elevator cage are also at inertia action, magnet stopper just closes immediately, therefore shake comparatively large, can impact steel structure, time serious, even damage steel structure.
Summary of the invention
For the problems referred to above, technical problem to be solved in the utility model is to provide a kind of novel elevating machine control system.In order to solve the problems of the technologies described above, the utility model technical scheme is just, a kind of novel elevating machine control system, comprise power module, control module and driver module, its constructional feature is, described control module comprises PLC and remote control module, and described driver module comprises coder, frequency converter and electrical motor; Described power module is connected with control module and driver module respectively, and described PLC is connected with frequency converter thus controls the output frequency of frequency converter, and described frequency converter is connected to control motor speed with electrical motor; Described coder is connected with electrical motor and monitors its velocity of rotation, and this coder is also connected with PLC and to the velocity of rotation information of its feedback motor; Described remote control module is connected with PLC and can changes it.
Preferably, described power module comprises mains supply and power converter, and described mains supply is connected with power converter, and it is also connected with electrical motor, and described power supply changeover device is connected with PLC.
Preferably, described novel elevating machine control system is also provided with weight limitor, and it is connected with PLC.The setting of weight limitor can be avoided elevator loading overweight and cause elevator to land suddenly.
The impulsive force that the utility model brings when starting and stop by arranging frequency converter reduction elevator, and then avoid elevator to be worn; In addition the utility model is also provided with coder, and it can detect motor speed, and feeds back to PLC, and PLC controls the output frequency of frequency converter according to the velocity of rotation of motor, the rotation speed change of motor can be avoided too fast and make motor impaired.
