Abstract
As the main force of modern port operation, cranes need continuous improvement to meet the needs of work production. This article takes the MQ4040 single arm portal crane as the research object, and carries out a scientific and rational design for the currently used portal cranes in the port. The designed portal crane is suitable for a variety of working environments. This article mainly introduces the design method and design process of the portal crane in more detail from the following sections.
(1) Overall calculation of portal crane. In this process, the calculation of the search point of the boom system was completed, and the design verification of the horizontal cargo displacement system and the boom self-balancing system was completed. Calculate the action load of the crane, including gravity load, wind load, yaw load of the cargo, etc., calculate the wheel pressure of the crane leg according to the applied load, check the stability of the crane and the safety of the anti-skid and anti-skid of the crane.
(2) The design calculation of the truss structure. Determine the structure and main dimensions of the rack and conduct detailed design and calculation of the important structure of the rack structure, checking the rationality of the structure layout.
(3) Three-dimensional modeling and finite element analysis of the truss structure. Using Solidworks to complete the three-dimensional modeling of herringbone structure, the use of ANSYS analysis software to complete the accurate force analysis and calculation of the human frame structure.
The characteristic of this article is to complete the overall design of the MQ4040 single-arm portal crane and the structure design of the herringbone with the aid of modern CAD design technology, which improves the efficiency of the design. The performance of the crane has been optimized to reduce energy consumption and reduce production costs, making the portal crane more suitable for the use of small and medium ports .
