Robot automatic temperature measuring and sampling device and control system thereof

Abstract

The invention relates to a robot automatic temperature measuring and sampling device and a control system thereof. The robot automatic temperature measuring and sampling device comprises a support frame arranged on a furnace cover, a temperature measuring probe used for mounting a temperature measuring bomb, and a sampling probe used for mounting a sampling bomb, wherein a swing rod is arranged onthe support frame, the temperature measuring probe and the sampling probe are respectively arranged at one end of the swing rod through a lifting mechanism, the lifting mechanism is used for enablingthe temperature measuring probe and the sampling probe to do reciprocating motion along the swing rod, the other end of the swing rod is hinged with the support frame, and a driving mechanism capableof enabling the swing rod to rotate along a hinged part is arranged on the support frame; and an emergency pulley mechanism is further arranged on the support frame, and is connected with the temperature measuring probe and the sampling probe through traction ropes. The robot automatic temperature measuring and sampling device can reduce the safety risk and labor intensity of manual operation, improves the stability and precision of temperature measurement sampling, is provided with the emergency equipment, and thus can reduce the risk that the probe is damaged by high temperature.

Description

technical field [0001] The invention relates to the technical field of temperature measurement and sampling of metallurgical LF furnaces, more specifically, it relates to a robot automatic temperature measurement and sampling device and its control system. Background technique [0002] LF furnace is the ladle refining furnace, which is the main refining equipment outside the furnace in steel production. In order to ensure the quality of continuous casting slabs in the production process of special steel, the molten steel smelted in the converter enters the LF furnace for refining to eliminate impurities in the molten steel. Under the existing operating conditions, it is necessary to manually use the temperature measuring gun device to insert into the observation hole of the LF furnace to measure the temperature of the molten steel multiple times, and accurately determine the temperature of the molten steel to provide accurate data for the production of the next process. The ...

[0003] Temperature measurement and sampling are two processes, and the existing manual temperature measurement and sampling work should be carried out separately

The steelmaking process is mainly operated manually. Manual temperature measurement and sampling are used for temperature measurement and sampling. The operation is completely dependent on manual disassembly and assembly of ammunition and holding guns. The labor efficiency is low. Since the steelmaking area is a high-temperature and dusty area, manual temperature measurement and sampling requires Workers approach the LF furnace at high temperature to measure temperature and take samples. During the refining process of the LF furnace, the molten steel will roll over and spray slag outside the furnace. There is also a safety accident that may cause personal injury due to slag splashing during this operation.

When measuring temperature and sampling, personnel not only have to face high-temperature operations, but also the operating environment is relatively harsh. Workers are exposed to high-temperature and high-dust environments for a long time, which is easy to cause harm to the body, which is not conducive to safe and stable production.

In addition, due to the different positions of the hand-held temperature measuring guns in manual temperature measurement, the measurement data is unstable.

Manual temperature measurement and sampling methods have disadvantages such as high labor intensity, low work efficiency, and high safety risks. Although the above manual operation methods have certain protective measures, there are still relatively large safety risks.
