[0028] The present embodiment provides a high-speed wire rod low-speed rolling mill measuring device, which is mainly used for checking and adjusting the center height and the end face of the rolling mill base during the maintenance of the high-speed wire rod offline rolling mill.
[0029] There are 14 high-speed wire rod low-speed zone rolling mills in total, mainly three types of rough rolling mills, intermediate rolling mills, and pre-finishing rolling mills. The three types of rolling mills have elevations of: 380 rolling mill center height 700mm, base end face 645mm, 480 rolling mill center height 820mm, base end face 712mm, 610 rolling mill center height 1000mm, base end face 915mm.
[0030] After reaching the service life, the arches on both sides of the rolling mill are first pulled out by the hydraulic cylinder, and the rolling mill core 7 composed of the roll system and the roll gap adjustment device is hoisted to the repair area by the overhead crane. According to the model of the offline rolling mill, the electric push rod 1 is used to push the connecting piece 13 to adjust the distance of the movable support beam 12, and the maintenance base is adjusted to the appropriate size to ensure that the base is stable and convenient for the placement of the rolling mill. After the rolling mill rolls and bearings are repaired, the center height of the rolling mill and the end elevation of the base need to be measured.
[0031] The elevation measurement method of the base end face is to first turn on the laser level 4, and manually adjust the lifting platform 3. The platform adjusts its height through the lifting screw 2 until the laser level reaches the specified height on the fixed scale 6. Fix the lifting platform 3. Lift the core of the rolling mill to be repaired onto the maintenance base 5, and then start the motor 8, which drives the moving screw 11 to rotate. The moving base 10 adjusts its position on the moving screw 11, and the laser level 4 is used to confirm and adjust the elevations on both sides and the middle elevation of the rolling mill end face until the installation size is within the standard deviation range.
[0032] The method of measuring the center height of the rolling mill is to use the rolling mill core roll gap adjustment device to adjust the roll gap to a fixed size, and prepare a standard gauge block to ensure that the gauge block matches the roll gap size. Manually adjust the lifting platform 3 according to the center height of the rolling mill, and adjust the height of the platform through the lifting screw 2 until the laser level reaches the specified height on the fixed scale 6. At this time, place the gauge block at the roll gap position at the laser, confirm the center height of the rolling mill through the gauge block and readjust the center height of the rolling mill until the laser is at the center position of the gauge block, which means that the installation size meets the requirements. Start the motor 8, the motor drives the moving screw 11 to rotate, the laser level adjusts its position on the moving base 10, and moves the position of the laser level to confirm the center height of the rolling mill on both sides and in the middle of the roll gap until the installation size is within the standard deviation range. After the measurement is completed, turn off the laser level, and lift the maintenance rolling mill from the maintenance base to the spare parts area through the overhead crane.
