Abstract

The invention discloses a remote intelligent decoking program control device which comprises a human-machine terminal device, a PLC control system, an executing mechanism system, a motion detection system and a data analyzing system, wherein the motion detection system comprises a tension detection module which comprises a fixed pulley, a movable pulley and a tension sensor, the tension sensor is fixed on a steel rope of the fixed pulley, the executing mechanism system comprises a boring winch and an electric tap, and the boring winch pulls a drill stem, a fulcrum bearing and a coke cutter to move up and down through a steel rope. According to the invention, the state and the working condition of the coke cutter are figured out through detecting the tension of the steel rope, thus the up-and-down movement and the rotating speed of the coke cutter are automatically regulated, the switching between a remote control and a coke cutting mode is realized, labor intensity of workers is lightened, and safety of operators is ensured.

Description

technical field [0001] The invention relates to the field of delayed coking hydraulic coke cutting, in particular to a remote intelligent program control device for decoking. Background technique [0002] At present, the domestic hydraulic decoking program-controlled system still stays in several aspects of controlling the lifting equipment of the decoking drilling tool winch, the switch of the decoking control valve and the start-up of the high-pressure water pump. The decoking process is also judged by manual on-site operation and manual experience. The current program control system is a semi-automatic working process, and the on-site operating environment is harsh and the operation efficiency is low. With the expansion and transformation of domestic old coking machines and the popularization of automatic top and bottom cover machines, automatic detection and automatic control of the decoking process are also imperative. If V—represents the vertical linear displacement v...
