The scientific design plan for aluminum alloy elevators includes leveling and locking circuits, telescopic balance circuits, variable amplitude balance circuits, and emergency decentralization systems. In order to make the platform in the hydraulic system or pipeline suddenly damaged due to accidents, to ensure that the workbench does not produce a sudden fall of the boom or workbench tipping endanger the safety of personnel equipment, we design for each system to take different situations Different options.
First, in the luffing system:
In addition to the same factors as the telescopic system, a similar oil path is provided in the rodless chamber because the luffing platform luffing cylinder is always in a compressed state.
Second, in the leveling system:
Because the up-flattened oil cylinder supports the workbench at high altitude, it only uses the downward pressure oil that the flat oil cylinder expands and contracts when the boom angle changes to make it follow the movement to ensure that the workbench is at any level. In the event of an accident, the reaction speed is required to be fast and the oil line is closed and reliable without any internal leakage. Therefore, the form of a pilot-operated check valve is adopted.
Third, in the telescopic system:
First of all, in the event of an accident, in addition to meeting the immediate automatic locking of the oil circuit, the personnel and equipment on the workbench must then be retracted by manually operating the door to allow the cylinder to retract. Secondly, due to the relatively large size of the oil cylinder, the internal leakage of the valve element is not very high. Therefore, a double hydraulic control one-way sequence valve is connected to the rod chamber of the telescopic cylinder and the oil inlet of the rodless chamber, and is also installed in the cylinder. The upper valve is in a position where the staff can operate below.
Fourth, consider the factors
In addition, the pressure and setting method required for each pressure regulating valve should be carefully considered and calculated in the design. Not only can the system work properly, it can also prevent the equipment from being used for excessive overload.
In short, with the development of science and technology, aluminum alloy elevators will be better and better in design.
