Problems solved by technology

[0004] In the current slag removal process, the walking control of the molten iron tank car is mainly controlled by manually controlling the travel button, and the jog button is used to realize the walking control of the molten iron tank car. Not in place or over-traveled, heavily dependent on manual experience, time-consuming and low-precision
It is also possible to detect the in-position signal by installing a proximity switch or photoelectric switch at a fixed position, thereby controlling the molten iron tank car to stop in place. However, due to the motion inertia of the molten iron tank car when walking, the positioning accuracy is poor. At the same time, the detection switch has no redundant control mechanism due to the harsh installation environment. , Once damaged, it will have a great impact on automatic slag removal

Embodiment Construction

[0022] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, an automatic walking control device for a molten iron tank car includes a PLC controller, a distance measuring sensor, a camera and an image processor. Displacement, the camera is installed at the walking destination of the molten iron tank car, and the collected walking images are transmitted to the image processor, the ranging sensor and the image processor are connected to the input end of the PLC controller through a cable, and the output of the PLC controller The terminal is connected with the traveling drive motor of the molten iron tank car through a cable.

[0024] The ranging sensor is mainly used to collect the real-time displacement of the molten iron tank car at a predetermined frequency, and transmit the collected real-time displacement to the PLC contro...

Abstract

The present invention provides an automatic walking control device and method for molten iron tank car. The device comprises a PLC, a distance measuring sensor, a camera and an image processor, the real-time displacement of the molten iron tank car is collected through the distance measuring sensor, and the PLC controls the walking speed of the molten iron tank car according to the difference value of the target displacement and the real-time displacement of the molten iron tank car to control the molten iron tank car to accurately and safely arrive at the destination. By means of the method, the time for the molten iron tank car to safely walk to the destination is effectively shortened, and meanwhile manpower input can be reduced.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy industry, and in particular relates to an automatic running control device and method for a molten iron tank car. Background technique [0002] In the field of iron and steel metallurgy industry, steelmaking is a very important part, and the slag removal process is an important part of the steelmaking process. The maturity of the slag removal process is not only related to the quality of downstream molten steel, but also related to the cost and benefit of iron and steel enterprises. In the primitive period of the steelmaking industry, the slag removal process was mainly realized by manually lifting the slag rake, which was not only inefficient, but also took a long time to remove slag, and the waste of molten steel was serious, and there was even a considerable risk of accidents. After the appearance of the slag removal machine, workers can realize the removal of slag from the m...
