The invention relates to a DC (direct current) converter valve hoisting system. The system includes control devices and mechanical devices, wherein the control devices include a position sensor, a PLC (programmable logic controller), a frequency converter and an operation power supply; the mechanical devices include electric hoists, a bearing structure, supporting structures, an electric pin penetrating / withdrawing mechanism, and a bearing steel beam; the supporting structures are connected above the bearing structure; the electric hoists are mounted on the supporting structures; the electric pin penetrating / withdrawing mechanism is arranged on the bearing steel beam; motors are mounted on the electric hoists; two ends of the frequency converter are connected with the motors of the electric hoists and the PLC respectively; the operation power supply is connected with the motors of the electric hoists; the position sensor is connected with the PLC and the electric hoists respectively; and the electric hoists are fixed on the bearing steel beam through the supporting structures and the bearing structure, thereby forming the hoisting system. The system adopts the high precision frequency conversion control, realizes the accurate synchronization control based on the four electric hoists, well solves the hoisting problem of a valve tray, and greatly improves the hoisting efficiency of the valve tray of a converter valve.
Description
technical field [0001] The present invention relates to a DC converter valve system, in particular to a DC converter valve hoisting system. Background technique [0002] The DC converter valve insulation type test usually requires a complete sample valve tower to be suspended on the top of the test hall for the test. Since the test hall is usually a steel structure and the suspension point is very high (30 meters), the total weight should be several The ten-ton diverter valve tower is suspended, and special hoisting equipment must be designed for the diverter valve tower hoisting. [0003] Hoisting DC converter valves on the engineering site usually requires special tools, but due to the one-time permanent installation on the engineering site, manual chain hoists are often used for hoisting operations, which is low in automation, time-consuming and laborious, and the hoisting efficiency is low. Contents of the invention [0004] The object of the present invention is to p...
