Application of scissor lift platform in food industry
Scissor lift platforms are widely used in civil aviation, transportation, metallurgy, automobile manufacturing and other industries, and are mainly used in the grain industry for loading machines and auxiliary lifting platforms. Today, the North China Lift Platform shares the application of the scissor lift platform in the grain industry:
1. Due to the frequent lifting and lowering of the scissor lift platform, the multi-rod mechanism is prone to fatigue damage under the action of random pulsating load. In order to prevent this from happening, the lifting mechanism should be physically modeled and subjected to finite element analysis to determine the dangerous point of the lifting device and the maximum stress value at the dangerous point.
2. In the structure of the scissor lift platform, the installation position of the hydraulic cylinder is very important. If the installation position is not suitable and the lifting mechanism is at the lowest position, the thrust required by the hydraulic cylinder will be increased. In order to reduce the maximum thrust of the piston, according to the structural characteristics and design requirements of the multi-rod mechanism, the model of the scissor lift platform should be established when the device is at the lowest position, and the finite element analysis should be carried out, and the most optimized hydraulic cylinder can be determined by using Matlab software. Good location.
3. In the construction of the scissor lift platform, the scissor arms are connected by pin shafts, and the relative movement and extrusion between the scissor arms are caused, so that the scissor lift platform wears during use. In order to solve this problem, the scissor lift platform needs to be mathematically modeled according to the materials, dimensions and ultimate loads of the scissor lift platform, and then static and dynamic analysis is carried out to analyze the multi-rod mechanism nodes. The law of motion, calculate the strength and stiffness of the multi-rod mechanism, and calculate the shear strength of each major pin.
