Hydraulic lifting platforms are very popular because they have many advantages, such as a very stable structure, a wide range of applications, and high work efficiency. There are many devices in hydraulic lifting platforms, such as controllers and hydraulic cylinders. When using a hydraulic lifting platform, we must operate it correctly according to the rules. Working principle of lifting and lowering; The hydraulic lifting platform adopts a hydraulic drive method, which supplies power to the DC motor and drives the high-pressure pump through the battery carried by the freight vehicle. The electrical energy of the battery is converted into high-pressure hydraulic energy of hydraulic oil, and the hydraulic cylinder is controlled by an electromagnetic valve to convert high-pressure hydraulic energy into mechanical energy, driving the four-bar linkage mechanism to move, thereby enabling the lifting platform to complete various actions such as upward and downward translation and upward and downward rotation. Design points: The structural design of the actuator is an important part of the hydraulic lifting platform design, and the selection and determination of the actuator are crucial. According to the function of the hydraulic lifting platform, the actuator should have the characteristics of upward and downward translation and rotation, that is, the lifting platform should be able to perform planar motion according to certain rules. By appropriate control (t ō ng gu ò), the lifting platform can complete various actions, such as rotating upwards when the structure of the hydraulic lifting platform is composed of up and down movements. When the platform is in position, it can rotate downwards for lifting and lowering. As long as the parallelogram mechanism and the positions of the points are determined, the entire mechanism can be fully determined. Load analysis is the basic step of structural design, and it is also the main basis for selecting and determining the power drive mode. The force analysis of the rotating hydraulic cylinder can be carried out through an isolation platform, and the hydraulic components are also easy to achieve universality and standardization. {4}
