Embodiment 1
[0018] In order to solve the problem that a large amount of lubricating glyceride, metal dust and organic solvents are accumulated on the measuring magnetic rod and detecting magnetic ring of the sensor in the rolling mill of the hot rolling production line, the wear of the measuring magnetic rod and detecting magnetic ring of the sensor is aggravated, and the magnetism is weakened. To detect signal obstruction and interference, the present invention effectively isolates the above-mentioned obstructions and interferences by adding an elastic protective cover. The core electronic warehouse of the sensor is the key processing part of the sensor. When water vapor escapes during mechanical maintenance operations, roll hoisting operations, and process production, it may directly collide with or damage the core electronic warehouse of the sensor. Through the invention The electronic warehouse fixing and protection device effectively protects the damage that may occur in the above-men...

The invention provides a protection device of a hot rolling channeling roll displacement sensor. The protection device comprises a magnetic rod protection cover and an electronic bin protection device. The magnetic rod protective cover sleeves the outer portion of the measuring magnetic rod of the displacement sensor, one end of the magnetic rod protective cover is fixed at the detecting magneticring of the displacement sensor, and the other end of the magnetic rod protective cover is fixed at the electronic bin tail cover of the displacement sensor; and the electronic bin protection device sleeves the outer side of the electronic bin body. According to the protection device, the technical problems that a hot rolling channeling roll displacement sensor is short in service life, detectiondata are distorted, and a detection magnetic ring and sensor magnetic induction are prone to abrasion are finally solved.
Description
technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to a protection device for a hot rolling roll shifting displacement sensor. Background technique [0002] The displacement sensor is a displacement detection device, which converts the real-time position of the vernier magnetic ring fixed on the movable device body into a 24-bit (Gray code) serial data format. After receiving the clock signal, the data is sent back to the host computer control unit in the form of serial communication, so as to meet the requirements of transmission, processing, recording analysis, storage and other requirements of measurement data. [0003] However, in the hot continuous rolling manufacturing industry, the process of the rolling mill must require cooling water, lubricating grease, organic solvents, etc., as well as some metal dust, water vapor or collisions during the process of production, resulting in a large amount of glyceride, metal ...
