【摘要】：大口径液压弯管机是在大型长距离的油气输送管线工程中用于改变管线方向的一种机械设备,弯管机可在野外现场作业具有提高工作效率,降低加工运输成本,简化制作工艺等特点。现如今在人们的工作生活中都少不了油气等资源的大量使用,然而对于油气开采之后的运输就成为了开采后的又一大重要工程。由于现有的大口径液压弯管机工作时还是主要依靠工人手动操作,自动化程度低,用工强度大。所以要对弯管机的工作原理进一步分析,实现弯管机在电气控制系统的监控下自动完成弯管作业的功能,减少用工人数,简化操作步骤,提高弯管作业的成功率。根据企业的实际生产需要,本文通过对大口径液压弯管机工作原理的分析,针对该设备存在的自动化程度低,工作过程繁琐和加工精度差的问题,分别提出了现有问题的解决方案,以及设计基于台达PLC的弯管机自动控制系统的研制方案。在充分分析了弯管机的工作流程、技术特点和重要参数的基础上,改造弯管机现有的液压系统,使液压系统满足电气系统功能的必要条件。通过分析弯管机的执行元件和重要参数,设计出电气控制系统的硬件组成和各个硬件设备的电路接线图。根据设备的作业要求,以台达公司的WPLSoft、DOPSoft、DCISoft1.12软件作为系统开发平台,编写PLC和触摸屏的控制程序。通过对大口径液压弯管机的技术参数分析,并应用PLC控制技术,完成了对弯管机自动控制系统的软、硬件设计。控制系统经过上机调试,实现了自动控制各执行元件有序稳定的工作并且满足企业的技术要求。验证了大口径液压弯管机升级改造的可行性,为油气建设工程提供更为高效的大口径钢管的弯管设备,该设备自动控制系统的实现具有一定的经济价值和应用价值。同时,还能使得大口径弯管机得到更加广泛的推广使用。
[Abstract]:The large-caliber hydraulic pipe bender is a kind of mechanical equipment used to change the direction of the pipeline in the large-scale long-distance oil and gas pipeline engineering. The pipe bender can improve the working efficiency and reduce the cost of processing and transportation in the field. Simplify the manufacturing process and other features. Nowadays, oil and gas are used extensively in people's working life. However, transportation after oil and gas exploitation becomes another important project after exploitation. Because the existing large caliber hydraulic pipe bender mainly depends on the manual operation of the workers, the degree of automation is low and the intensity of employment is large. Therefore, the working principle of the pipe bending machine should be further analyzed to realize the function of the pipe bending machine automatically completing the pipe bending operation under the supervision of the electric control system, to reduce the number of workers employed, to simplify the operation steps, and to improve the success rate of the pipe bending operation. According to the actual production needs of the enterprise, this paper analyzes the working principle of the large-caliber hydraulic pipe bending machine, aiming at the problems of low automation, tedious working process and poor machining precision of the equipment. The solutions to the existing problems and the design of automatic control system of pipe bender based on Delta PLC are presented respectively. On the basis of fully analyzing the working flow, technical characteristics and important parameters of the pipe bending machine, the existing hydraulic system of the pipe bending machine is reformed to make the hydraulic system meet the necessary conditions for the function of the electrical system. The hardware composition of the electric control system and the circuit wiring diagram of each hardware equipment are designed by analyzing the executive components and important parameters of the pipe bending machine. According to the operation requirements of the equipment, the WPLSoft,DOPSoft,DCISoft1.12 software of Delta Company is used as the system development platform, and the control program of PLC and touch screen is compiled. By analyzing the technical parameters of large caliber hydraulic pipe bending machine and applying PLC control technology, the software and hardware design of automatic control system of pipe bending machine is completed. The control system has been debugged on the computer to realize the orderly and stable work of the automatic control components and to meet the technical requirements of the enterprise. The feasibility of upgrading the large-caliber hydraulic pipe bending machine is verified, and more efficient pipe bending equipment of large-caliber steel pipe is provided for the oil and gas construction project. The realization of the automatic control system of the equipment has certain economic value and application value. At the same time, it can make the large-caliber pipe bender more widely used.
