Problems solved by technology

[0011] Therefore, in order to overcome the deficiencies in the existing method that the installation equipment is affected by the high temperature on the torpedo tank car body, the external influence of the ground track bed, the mechanical switch is not in place, the value of the installation distance needs to be different according to different torpedo tank models, and the logic control is complicated. , The invention provides a method for locating a molten iron torpedo tank car to realize the positioning of a molten iron torpedo tank car by non-contact sensing the temperature of the target, effectively avoiding the problems of existing methods

Embodiment Construction

[0027] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0028] The present invention utilizes the characteristic that the internal temperature (about 1200°C-1400°C) of the mouth of the molten iron torpedo tank has a large deviation from the external temperature (below 400°C), and utilizes the non-contact sensing of two scanning hot metal detectors installed above the torpedo tank The temperature of the target is used to realize the positioning of the molten iron torpedo tank car. The schematic diagram of the installation position is as follows: figure 1 Shown:

[0029] When the molten iron torpedo tank car travels into the sensing range of the detector, only two detectors output actions at the same time, indicating that the position of the torpedo tank car at this time is the positioning position. Connecting the output signal of the detector to the interlocking alarm system can realize automatic positioning, and ...

Abstract

The invention discloses a method for positioning molten iron torpedo tank trucks, and belongs to the technical field of methods for positioning tank trucks. The method has the advantages that the temperatures of torpedo tank targets are sensed in a non-contact manner, accordingly, the molten iron torpedo tank trucks can be positioned, torpedo tank truck positioning requirements for filling the torpedo tank trucks with molten iron by tapping holes of metallurgical blast furnaces, filling molten iron trucks with molten iron by the torpedo tank trucks of steelmaking pouring stations, measuring the weight of the molten iron in the torpedo tank trucks or measuring the liquid level of molten iron in torpedo tanks and the like can be met, and the problems of filled molten iron overflow or influence on the detection accuracy and the like due to positioning errors can be solved; the method can be implemented by few equipment, logic structures are simple, maintenance is simple and convenient, the maintenance cost is extremely low, the method can be popularized and applied to automatically detecting the liquid level of liquid surfaces of the molten iron in the torpedo tank trucks and automatically measuring the weight of the molten iron, and the like.

Description

technical field [0001] The invention specifically relates to a positioning method for a molten iron torpedo tank car, and belongs to the technical field of tank car positioning methods. Background technique [0002] At present, the positioning of torpedo tank cars is mostly carried out by the dispatcher's visual positioning, and the method of contacting the locomotive driver through the walkie-talkie. When the torpedo tanker arrives near the parking location, the dispatcher issues a parking command, and the locomotive driver stops immediately. During this process, the dispatcher only uses his eyes to observe and judge, and cooperates with the command to make the torpedo tanker stop at the location. There is inertia when parking, and the locomotive still continues to move forward for a certain distance to stop. At this time, the parking position of the torpedo tanker will deviate from the positioning point, sometimes exceeding ±30cm, and the alignment is not accurate. Throug...
