The detailed description of garbage grab crane:
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 operation features, developed a set of specially designed for garbage grab crane frequency control of motor speed control method, make the crane can be stable and reliable operation.Composed of two garbage grab crane crane handling system (a job, a case), is used to complete the garbage for MSW incneration 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. switch module To realistic, the picture is clear, colorful, 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 process sequence, 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 mature vehicle driver operation when asked, 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.
