The stationary scissor lift platform bracket is composed of 8 steel columns with substantially the same shape and rectangular cross-section, and cylindrical short shafts are processed at the top and end of the bracket to facilitate the installation of the bracket. The main function of the bracket in the elevator structure is load support and motion transformation, and the telescopic movement of the hydraulic cylinder is converted into the lifting movement of the scissor platform through the hinged fulcrum. The structure of the bracket should not only meet the installation requirements, but also ensure that With sufficient rigidity and strength, it can run smoothly and safely in the lifting movement for a period of time.
How to calculate the force on a scissor lift?
By analyzing the movement form and force of the scissor lift bracket, it is found that the force situation of the bracket during the movement is relatively complicated. Therefore, this problem is a statically indeterminate theoretical problem. Based on the principle of qualitative analysis and improving efficiency, the force that has no many influence on the deformation of the beam can be ignored, and it can be handled in this way without changing its original properties. According to this principle, the force received by counterfeiting is analyzed again, and it can be seen that the force of the connection point with the hydraulic cylinder ejector is the most important force received by the house. It is not only affected by the thrust of the hydraulic cylinder, but also by The force transmitted by the upper roof, therefore, the force of the thick upper roof plate of the bracket connected with the hydraulic cylinder ejector rod is the most important force it receives. Here, other forces are ignored, and only the upper roof plate is calculated. The load force transmitted by the load and self-weight.
