Research On Crane Loading Test Device

Crane is a logistics tool which plays an important role in industrial production.The crane has many categories,and most of them belong to the gantry crane.The crane must be inspected after the new installation,and load test is a very important link of inspection.This paper presents a new project of crane’s static loading test,making use of the pulling force of the crane to complete the test.Compared with the traditional project,this new project can greatly reduce the test cost.It is helpful for inspection organization to improve the inspection and increase the efficiency of inspection.The main work and achievements of this paper are as follows:1.Design a project of crane’s static loading test,complete the test with using the crane’s pulling force,analysis the press of crane’s steel pillar,to validate the safety performance of the crane and its steelpillar,and the practicability of this project.2.Set a simplified model of a portal frame composed of steel pillars and beams,analysis the press of the model by mechanics of materials analysis methods and computer simulation for ANSYS,to conclude that the horizontal force on the steel pillars has little influence on the steel pillars in the load test.3.Design the Accessories of the crane’s static loading device,complete the design and checking of the hoop device and the horizontal supporting device,and make them out.Propose a new type of hydraulic compensation system for the horizontal support system,and complete the simulation analysis.4.Complete the crane’s static loading test,and carry it out.By comparing the results with the finite element analysis results,it meets the design expectations.The design of the project of crane’s static loading test and the actual test show that the project can be implemented and popularized,and it will be tested in larger tonnage equipment in the future to define the scope of the project.
