Abstract:

Abstract In order to improve the automation degree and unloading efficiency of the ship unloading control system of the large coal-fired power plant, the structure, operation principle and workflow of the bridge-type grab ship unloader in a coal-fired power along the river are analysed, and the control system of ship unloader software based on PLC is studied and designed. The designed control system of bridge grab ship unloader is convenient to operate under different working conditions and improves the automation degree and efficiency of coal unloading and also provides an application example

Abstract:

In order to get the displacement response curve of the Portal Crane under four phase of unloading process, the vibration system was built, the vibration differential equation and displacement response expression were deduced, combining with the actual case, the displacement response expression and displacement response curve were deduced in the open grab time 1.5 s and 4 s. The results show that: the unloading process is an important factor affecting the structural vibration; Displacement peak and open grab time are inversely proportional; Increase the open grab time can reduce the vibration o

Abstract:

The swing of the grab is a main factor affecting the working efficiency of overhead cranes. Thus, planning the optimal motion path can reduce the adverse effects caused by the grab swing and improve the loading and unloading efficiency. The dynamic model of the trolley–grab system is established by considering factors like the change of rope length, wind load, and air resistance. First, the radial basis function neural network is applied to generate a feasible motion trajectory of the crane trolley. Taking the swing angle and angular velocity of the grab at the discharge point as evaluation, t
