Loading machinery comprehensive training platform

  Product name

  Loading machinery comprehensive training platform

  Model (Type)

  HKZZJX type

  Feature

  Hydraulic loaders are the main machinery in mechanical engineering. They are widely used in engineering construction, road construction, hydraulic engineering, national defense fortifications and other earthwork construction and mine loading operations. Loaders are widely used as mobile machines in the loading, lifting and transportation of earth moving, stone, loose goods and piles of goods, and they also have light shovel capacity.

  In recent years, the application of high-tech microelectronics technology in hydraulic technology has made the comprehensive technical level of construction machinery and construction machinery higher and higher, improved the reliability, operational safety, comfort and service life of these machinery, and its adaptability is more powerful.

  1. The test bench is made of cold-rolled steel plate (and has been sprayed and treated with anti-corrosion), with a desktop structure and integrated control and operation.

  2. The electrical operation control is under-mounted, and the hydraulic station is placed in the main cabinet of the hydraulic table. The overall structure is compact and coordinated, the layout is beautiful and generous, and the practicability is strong, which can be used for 4-6 people to experiment.

  3. The all-metal structure of the loading machine is scaled down according to the actual object. During the experiment, the hydraulic system is activated to operate the machine according to the experimental requirements.

  4. The loading machine is made according to the structure and scale of the real object, which can truly reflect the actual working conditions of the machine, so that students can deeply understand the structure and working principle of each component of the machine in the experiment.

  5. The experimental control adopts manual control and automatic control.

  6. The experimental part adopts pressure-resistant rubber hose, and the pressure can reach 25Mpa.

  7. With three-phase leakage protection, the output voltage is 380V/220V, and the power supply is cut off when the leakage current to the ground exceeds 30mA; the electrical control adopts DC 24V power supply, and has overvoltage protection to prevent misoperation from damaging the equipment.

  Training contents

  1. Demonstration control experiment of hydraulic loading machinery

  1) During the loading operation, the rocker arm cylinder is extended after the bucket is loaded, so that the bucket is reversed and the boom is lifted;

  2) Unloading operation, the bucket is unloaded (the rocker arm is retracted to turn the bucket), and the boom is lowered.

  2. Programmable Logic Controller (PLC) electrical control experiment: machine-electric-hydraulic integrated control experiment.

  1) PLC instruction programming, ladder diagram programming learning;

  2) Learning and use of PLC programming software;

  3) Communication and online debugging between PLC and computer;

  4) Application of PLC in hydraulic transmission control and optimization of control scheme.
