Problems solved by technology
[0002] At present, in the existing converter or AOD furnace steelmaking, the height of the oxygen lance and the slack and tightness of the oxygen lance steel wire rope are sometimes used to send the detection signal to the converter control system through the method of engineering projects. Due to the software of each project Software development is carried out by engineers, so there are disadvantages such as insufficient detection accuracy, unstable signal, long debugging cycle, high system cost, etc.; Altitude and speed to compensate will not be able to detect accurately

Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 , figure 2 As shown, the oxygen lance height and the oxygen lance wire rope tightness integrated detection device of the present invention include:
[0018] The absolute value type multi-turn Green code encoder 2 is connected with the external main control system through the PLC1 of the PLC system 3, and is arranged on the shaft of the drum 4 wound with the steel wire rope 5, and is used to measure the rotational speed and real-time rate change of the drum;
[0019] The load cell 8 is used to measure the tension of the wire rope, and is arranged on the fixed pulley 6, and the wire rope between the roller 4 and the oxygen lance 7 is wound 5 on the fixed pulley 6, and output to the weighing transmitter 9 Pressure signal, the wire rope between the fixed pulley and the roller is roughly in the horizontal direction, which...

The invention discloses a device for integrally detecting the height of an oxygen lance and the looseness and tightness of a steel wire rope of the oxygen gun, which aims to solve the problems of low reliability of a detection signal and the like in the prior art. The height of the oxygen lance and a looseness or over-tightness signal of the steel wire rope are detected integrally; meanwhile, thelooseness or the over-tightness of the steel wire rope is detected by a method of directly detecting the speed compensation of a tension combining encoder of the steel wire rope and the length changecompensation of the steel wire rope by using a weighing sensor. The structure and the method solve the problem of the integral detection of the height of the oxygen lance and the looseness and over-tightness signal of the steel wire rope of the oxygen lance, and the detection device can accurately detect the looseness and over-tightness of the steel wire rope according to the operation speed of the oxygen lance and the length compensation and the tension of the steel wire rope of the oxygen lance, so that the stability and reliability of the detection are improved and equipment investment canalso be saved.
Description
technical field [0001] The invention relates to a detection device, in particular to an integrated detection device for oxygen lance height and oxygen lance wire rope slack and overtightness in the converter steelmaking process of metallurgical enterprises Background technique [0002] At present, in the existing converter or AOD furnace steelmaking, the height of the oxygen lance and the slack and tightness of the oxygen lance steel wire rope are sometimes used to send the detection signal to the converter control system through the method of engineering projects. Due to the software of each project Software development is carried out by engineers, so there are disadvantages such as insufficient detection accuracy, unstable signal, long debugging cycle, high system cost, etc.; If the altitude and speed are compensated, the detection cannot be accurate. In view of the strong function and low price of the current small PLC system, the height of the entire oxygen lance and th...
