Product Description

   Because garbage grab crane work level is higher and the characteristics of the crane itself, brings to the system is stable and reliable operation of the big challenges, our company through working accumulation and summary in the crane industry garbage grab the running characteristics of garbage has developed a set of specially designed for grab crane design of frequency control of motor speed control method, make the crane to stable and reliable operation.Made up of two garbage grab crane crane handling system (a job, a backup), used to complete the wastes incineration power plant feeding and pouring pile, mixing, move and broken material, etc.Each crane have their own independent of the electric control system, operating console and HMI display panels, according to the needs of users can provide manual, semiautomatic control system.Hand, automatic switching convenient and quick.Mainly has the following features:
1, large range of speed: because of the characteristic of the garbage to grab and efficiency requirements, make the system control requirements is very big, our company can according to user's need to provide more than level speed stepless speed regulation and choice.
2, smooth operation, using the optimization of the motor torque output in the effective control of acceleration and deceleration traffic to avoid grab dangle, which not only make the system run smoothly, to the weighing system provide a good environment.Weighing system and control system, and cooperate with each other but independent design side of the fault does not lead to another set of system can't work normally.
3, a variety of control mode and method of instruction: a V/F control, vector open-loop or closed-loop control vector.On the user's special circumstances, we have a variety of instruction methods to choose from, there are potential rod, 2-4 command console, 0 ~ 10 v or 4 ~ 20 ma analog signals, etc.
4, convenient hand, automatic switching: through simple setting, system can run in the automatic state, provide automatic feeding, pour the crib and weighing function, at the same time can provide to protect themselves, at the same time, as long as the operator has input (except for automatic operation of the data set), can be restored to manual operation, in order to ensure safety."Convenient, manual switch priority".Efficient automatic mode.
A. automatic feeding: such as feeding, as shown in the picture just click the touch screen to select material taking two positions and feeding throat opening, charge weight, set up the system can automatically finish feeding, greatly reduce the work intensity of the operators.
B. automatic reverse buttress: such as pour pile shown in picture, just click the touch screen to select material taking two positions and feeding position, set up pour pile weight and the system automatically pour pile after pile height.
C, perfect monitoring and a variety of reliable and effective protection measures: there are regional protection, grab tilting prevention measures and collision, limit switch, etc., at the same time as the lifting mechanism, also equipped with a heavy hammer type emergency limit.Chain control and discharging system.Through the chain control and unloading system, can protect the grab and discharging car, prevent the collision, to ensure safety.
Garbage grab crane electric control system overview: crane electric control system adopts advanced "touch screen + PLC + frequency control of motor speed control system, realize the whole machine comprehensive monitoring, automatic control and high precision of speed control function.Except crane agencies (grab) all adopt the digital frequency conversion speed regulating device, the machine adopts PLC control, can realize automatic grab crane, carrying, garages, and other functions, namely, manual/automatic operation.
Crane semi-automatic operation mode: automatic run to take material position, manual closing the grab, then according to the feeding address set, crane under program control, automatic operation to the feeding position, to realize weighing and record the weight of the bucket garbage, open grab, will waste into the hopper, feeding is completed automatically return to the landfill, completing the process of feeding.
Weighing: crane trolley frame set up a set of weighing device, with automatic peeling semiautomatic weighing, display, cumulative, printing, etc, used for process measurement and overload protection.Weighing indoor display device in driver, used for feeding, statistics, records to show the various parameters.Weighing accuracy is 1%, and through the signal transmitted to the control room, by the control of microcomputer measuring print report history query and so on, also have overload alarm function of the weighing system.
Manipulation of the driver room: equipped with crane agencies operating mechanism, the controller installed on the linkage, control of lifting, cart, the car running mechanism of the control cabinet.Controller is a standard interchangeable, contact contact.The driver interior also has the power key switch, such as start, stop, emergency stop button operation control box.And in the appropriate position with garbage door open the control button.Auxiliary equipment: lighting: the crane bridge (4 or 3 light auxiliary lighting.
Warning: crane bridge frame alarm bell, bell stage of control by the linkage of the foot switch control, driving the driver can switch, the alarm signal of driving.
Reliable safety protection measures: using air circuit breaker and phase sequence protector for the whole system and the subsystem of the short circuit, over-current, overheating, disconnected equal protection.Using the protective function of frequency converter to the driving operation of short circuit, over current, motor overheating protection, under voltage, over voltage, grounding, short circuit, stall to prevent overheating, heat sinks, brake unit overheating protection, etc.The run position is detected by rotary encoder, automatic control, the height of lifting mechanism display.Using limit and travel switch to the second level limit protection.
A friendly operation interface), semi-automatic control touch screen operation is comfortable, control switch to simulate lifelike, the picture is clear, bright colors, menu design conform to the requirements of the habit, easy to understand.Set up a command button on the screen and action buttons and function buttons.After the command input control system, control system according to different applications, and each branch program arrangement according to the requirement of the instruction into a complete program, the command of the crane to complete the instructions.B) operating linkage, the design of the operating handle full consideration when driving the driver operating requirements, accord with human body engineering principle.C) the driver seat backrest Angle is adjustable to meet the needs of the different height of the driver comfortable operation.
