When designing the organization plan for the scissor electric lifting platform, attention should be paid to the following difficulties (Emerson): As mentioned earlier, when increasing, the value decreases; When decreasing, the P/Q value increases. Clearly stating that the overall structural value decreases; As the P/Q value increases and decreases, the hydraulic lifting platform service platform lift stroke will decrease under the condition that the hydraulic cylinder stroke will not change; On the contrary, it will increase the force on the stroke of the hydraulic cylinder. Therefore, when designing the plan, it is necessary to fully consider the two elements of elevator travel and hydraulic cylinder force. Under the premise of considering the lift travel and overall structural specifications, choose a higher initial value. And in all organizations, the AB support frame is a key load-bearing component that bears a large bending distance, so the compressive strength should be checked as the top priority.
The hydraulic cylinder can be a single effect cylinder or a dual effect cylinder, but it depends on the specific conditions. Generally, we use single effect plunger pump cylinders, which are more economical and have less overall leakage and longer hydraulic seal life. When using a single effect plunger pump cylinder, full consideration should be given to overcoming the sealing friction resistance between the hydraulic cylinder piston rod and the engine cylinder body when the weight of the tablet computer is unloaded. Otherwise, it will cause the hydraulic lifting platform to fail to descend.
