At present, the position detection devices of the intermediate roll transverse oil cylinder of 1200 and 1450 six high reversible rolling mills are all installed in the transverse oil cylinder of the intermediate roll transverse rack. In the production process of the rolling mill, the magnetostriction detection can be caused by frequent washing and soaking with emulsion and oil leakage inside the oil cylinder Displacement sensor The circuit board is often burned out when water or oil enters. Because the magnetostrictive sensor is installed upward on the transverse movement, it often causes the magnetostriction to be changed when the work roll is connected with the cross shaft or when the maintenance personnel repair and when the backup roll is filled with oil and inserted with oil mist pipe Displacement sensor The sensor is short circuited and damaged due to the broken wire insulation magnetostrictive displacement sensor It is used to detect the telescopic position of the traverse oil cylinder, so as to automatically adjust the extension and extension of the traverse oil cylinder. That is, when one displacement sensor of two oil cylinders on a traverse rack is damaged, the two oil cylinders will be out of sync, thus the connecting plate of the traverse frame will be damaged. Therefore, it is often caused that the unit stops, and it is very difficult to replace and install the sensor, which is time-consuming and laborious to maintain The production cost is high, and the starting rate of the equipment and the production efficiency of the rolling mill are reduced.
summary of the invention
The problem to be solved is to overcome the shortcomings of the existing technology and provide a displacement sensor of the middle roll transverse movement mechanism of the six high reversible rolling mill. The sensor is not only reasonable in design and reliable in use, but also improves the working efficiency.
The beneficial effect of the utility model is that the structure is reasonable and the use is reliable, which avoids the sensor burning caused by frequent flushing and soaking of emulsion and oil leakage of oil cylinder, and the sensor is damaged when the maintenance personnel replace the cross shaft or add oil to the backup roll or insert the oil mist pipe shaft, so as to avoid the damage of the connecting plate of the traverse frame and the frequent replacement of the displacement in the transverse oil cylinder The sensor reduces the failure rate and downtime of the equipment, reduces the maintenance cost and improves the production efficiency.

Specific implementation mode
Referring to Fig. 1, the displacement sensor of the middle roll transverse movement mechanism of the six high reversible rolling mill is composed of a linear displacement sensor 1 connected under the base 7 of the fixator, a tie rod 2, a fixed bracket 3 and a fixed cross seat 4. The utility model can be used to connect the oil cylinder of the utility model by moving it horizontally by 5 inches.
The utility model only needs to be measured directly with a multimeter on the site. The maintenance and installation are convenient and simple, the equipment maintenance cost is low, the maintenance time of the equipment is reduced, the operation is stable, the production cost is reduced and the starting rate of the equipment is improved.
