[Abstract]:With the rapid development of China's economy, the demand for energy, especially oil resources, is rising rapidly. In order to reduce the excessive dependence on imported oil and ensure the security of our energy supply, To develop offshore oil in deep water has become a strategic choice for our country. The purpose of this paper is to develop the experimental prototype tool library of deep water pipe flange bolt connection machine with independent intellectual property right for 10m water depth connection test. This paper mainly carries on the deep water pipeline flange bolt joint machine tool library structure. Design and control system research. This paper summarizes the domestic and international research status of the related technical fields of flange bolt connection in deep water pipeline, emphatically analyzes the working principle and structural characteristics of the existing flange bolt connection working equipment abroad, summarizes and compares its advantages and disadvantages. To provide technical reference for the study of the subject. According to the requirements of the project, the overall scheme of the deep water pipeline connection machine is designed, and the machine and tools are determined by the bolt library, nut library and extender library, etc. According to the overall scheme, the form of the connection bolt is determined, and the pre-tightening method of the bolt is selected. By comparing and analyzing the calculation criterion of pipeline design and calculating the pretightening force of bolts needed for pipe flange seal, the operation flow of machine and tool connection is planned. The structure of tool library is designed in detail, and the working principle of clamping positioning mechanism, nut tightening mechanism, drawing module mechanism and circulating drawing mechanism are expounded. The 3D structure model of tool library is established by using Inventor software. The structural strength and stiffness of key parts are analyzed by finite element method. According to the actual requirements of the control of the machine and tools, the tool library control system is designed, the hydraulic control loop of the main movement mechanism is designed, the hardware of the electrical control system is determined, and the electrical control system is designed. Through the core principle test device, the comparison test of nut introduction is carried out, and the influence of relevant factors on nut introduction is analyzed. To verify the feasibility and reliability of the bolt introduced into the design scheme, to test the motor fluid resistance and the mechanical friction of the sleeve module, to reduce its adverse effect on the synchronicity of the nut sleeve rotation, and to complete the testing of the onshore connection of the machine and tools, The test process is recorded and analyzed, which provides a reference for the pool connection test of the prototype. Through the development of tool library for testing prototype of connecting machine and tools, this paper lays a foundation for the development of engineering prototype of flange bolt connection for deep-water pipeline in the future, and provides technical support for the operation of backjoint of deep-water pipeline.
