The electronic gearbox of the bucket wheel dredger has the characteristics of high transmission precision, wide transmission ratio range, convenient adjustment, etc. It can replace the mechanical transmission chain to achieve accurate transmission relationship. , Electronic gearboxes have broad application prospects. The company has carried out in-depth and systematic research on the system structure, implementation method, servo control and application of the electronic gearbox in the transmission of the cam CNC turning system. The main research work is to compare and analyze the electronic gearbox and the general CNC system. , pointed out that the electronic gearbox is a special kind of numerical control system, the fuel consumption of the 500-square bucket wheel dredger excavator, according to the different realization principles and control methods, the structure of the electronic gearbox is divided into the master-slave type based on tracking control and the one based on tracking control. The parallel type of fixed value control is analyzed; the transmission accuracy of the electronic gearbox and its influencing factors are analyzed, and the selection principle of the structure of the electronic gearbox is explained.
Bucket wheel dredgers are divided into non-self-propelled, steel, electric, hydraulic transmission and bucket wheel dredgers. The whole ship consists of hull structure, body equipment, pile walking system, dredging system, electric power system, hydraulic system, control system, etc. The hull adopts a square and transverse frame assembled box-shaped structure, which mainly includes two parts: the main hull and the side pontoons. The main hull is used to install all dredging shuttle equipment, and the side pontoons are used to ensure the longitudinal and lateral stability of the dredger. . The whole bucket wheel dredger is driven by electricity, and the 380V, 60 H2 high-voltage shore power is directly transmitted to the dredger to drive the whole ship’s power equipment and other electrical facilities. The traversing device, bucket wheel frame lifting device, positioning pile lifting device and car-joining device are all hydraulically driven. The ship is equipped with 2 high-power motors (mud pump motor and hydraulic pump motor) as the power source for the dredging operation of the whole ship. The mud pump motor drives the mud pump, and the hydraulic pump motor drives the 4 gear pump. The operating system and monitoring system are controlled by programmable logic controller (PLC). The motor is started with a soft starter. The forward movement of the ship is realized by the movement of the positioning pile and the truck. For the bucket wheel dredger, the positioning pile is lifted by the hydraulic cylinder.
The working method of the bucket wheel dredger is that the bucket wheel near the suction port cuts the soil body of the riverbed, and by rotating the bucket wheel, the cut soil body and water are fused into high-concentration mud, which is directly transported to the suction head at the top of the suction pipe. Relying on the suction effect of the centrifugal pump, a certain degree of vacuum is generated in the suction pipe, and the suction head at the front end of the suction pipe and the suction pipe are pressurized by the mud pump to transport the mud through the sludge discharge pipeline to the sludge discharge plant. The construction effect of continuous excavation is achieved through the vertical forward movement and lateral swing of the positioning hull of the dredger by the positioning pile rising and falling and the lateral movement winch.
