Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] The embodiment of the present invention mainly adds a position sensor on the operation side, and uses the logic and data calculation of PLC to automatically switch to the sensor on the operation side when the original transmission side position sensor fails, so as to avoid detection failure and maintain the safety and security of the equipment. Production continues. It is suitable for similar equipment such as hot-rolled coil boxes to ensure stable, safe and reliable operation of the equipment.
[0024] as attached figure 1 with 2 Shown are the left (transmission side) and right (operating side) views of the double interlock protection device for hot coil box equipment according to the embodiment of the present invention, which includes pinch roller senso...

The invention discloses a coil box equipment double-interlock protection device, and belongs to the technology of steel rolling equipment. The coil box equipment double-interlock protection device comprises a pinch roll sensor (1) of a transmission side, a pinch roll sensor (6) of an operation side, a position roll sensor (2) of the transmission side, a position roll sensor (7) of the operation side, a 2L roller position roller (3) of the transmission side, a 2L roller position roller (8) of the operation side, a 1A roller position roller (4) of the transmission side, a 1A roller position roller (9) of the operation side, a 1B roller position roller (5) of the transmission side and a 1B roller position roller (10) of the operation side. The invention further discloses a coil box equipment double-interlock protection control method. The coil box equipment double-interlock protection device and the control method of the coil box equipment double-interlock protection device lay emphasis to solve the problem that detection failure of the sensors result in equipment damage or production halts when the hot rolling coil box works under a hot and humid severe working condition environment, can well relieve the time pressing stress caused by sudden failures of the coil box in the compact production process, and can guarantee the safety of equipment and continuity of production when the sensors are detected to fail to work.
Description
technical field [0001] The invention belongs to the field of steel rolling equipment, and in particular provides a double-interlock protection device for hot coil box equipment and a control method thereof. Background technique [0002] The hot coil box equipment is usually installed between rough rolling and finishing rolling, and is used to coil the intermediate billet sent from the rough rolling area at high speed, and then send the intermediate billet to the finishing rolling unit at a low speed after uncoiling. However, the structure of the hot coil box equipment is complex, especially the pinch rollers, position rollers, 2L rollers, 1A rollers, 1B rollers and other roller systems all require long-stroke movements. The movement stroke detection device is several SSI sensors installed on the transmission side ( MTS linear position sensor or code wheel). [0003] When using the original equipment control, there are the following problems: the hot coil box works in a high...
