XJ350Workover Rig Derrick Car Design And Experimental Study

As a key drilling workover equipment, car decoration Well machinebecause low failure rate, easy operation, safe and reliable transport andgood performance, to meet the needs of a variety of drilling and workoveroperations. The same time as drilling and workover operations to expandthe international market for car decoration hoist further increase demand.Car oil workover rig derrick is a key component in the workoveroperations to put crane, crane travel suspension system for starting up thetubing, tubing emissions, handling accidents and other downholeworkover. Derrick safety is directly related to the performance of entireproduction run workover systems. For derrick hosted space steel structureof this complex, there is often a process of using transportation,overloading and corrosion and other factors, and suffered loadsrandomness, the occurrence of damage and destruction is greater potentialdanger to the structure security is threatened. Some of the importantcomponents in the event of structural damage, the extent of damage that itwill develop rapidly, causing a catastrophic tragedy. In order to protectlife and property safety, reduce significant economic losses, and takeeffective technical means and methods of on-board safety and assess thederrick structure is particularly necessary and urgent. In this paper, the use of safety car workover rig derrick involved in theevaluation of key scientific and technological issues has beensystematically studied, the main research contents and results are asfollows:(1) on-board workover rig derrick derrick numerical analysis methodsfor the design. Based on the finite element method, by means of generalanalysis software is proposed workover derrick car mechanics calculations.By car workover rig derrick bearing performance analysis reveals derrickinstallation, deformation, the use of structural characteristics.(2) according to vehicle characteristics workover rig derrick itself,research and development of wireless stress testing techniques, applied tothe vehicle structure workover rig derrick safety testing on. Complementtraditional testing only pay attention to the appearance of detecting,diagnosing and generally easy handling and prevention of defects.
