Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for the installation and correction of mechanical equipment, and in particular to auxiliary tools for the installation and correction of support rollers for ring furnaces. Background Technology

[0002] The annular furnace body is a closed circular track. Silicon steel coils (or strips) are typically placed upright on trolleys or cantilever supports and move cyclically along the track to achieve continuous production. Compared to roller hearth furnaces or bell-type furnaces, it offers better temperature uniformity and is suitable for mass production. The installation of support rollers is the first step in the installation of the annular furnace. The number of support rollers is usually greater than 200, and traditional installation and alignment methods are inefficient. Summary of the Invention

[0003] In order to improve the efficiency of the installation and correction of the support rollers of the annular furnace, this utility model discloses an auxiliary tool for the installation and correction of the support rollers of the annular furnace.

[0004] An auxiliary tool for installing and calibrating support rollers for an annular furnace includes a channel steel base and angle steel legs. The width of the angle steel legs is half the corresponding side length of the channel steel base, and the edges are aligned. The height of the angle steel legs is the same as the height of the channel steel base. Triangular grooves are engraved on the center lines of the horizontal and vertical directions on the upper surface of the channel steel base, and they intersect at a point in the center of the channel steel base. The length of the channel steel base is the same as the width of the corresponding support roller.

[0005] The channel steel base and angle steel legs included in this utility model are both made of thick steel plates through machining. They are mounted on the roller surface and aligned with both ends in the thickness direction of the roller. The top is leveled by a 0.02mm / m strip level, and the center of the top is the center of the roller.

[0006] This invention overcomes the difficulties of cumbersome installation and disassembly of auxiliary tools and low calibration efficiency in traditional calibration auxiliary work. It is suitable for auxiliary work of calibration of support rollers, especially for the installation and calibration of a large number of support rollers arranged in a circle, and the measurement is accurate and efficient.

[0013] A certain ring furnace has a furnace center diameter of 53.5m and 240 circumferentially arranged support rollers at the furnace bottom, 120 in the inner ring and 120 in the outer ring. The inner and outer rings share a common center point. The support rollers need to be installed and aligned.

[0014] First, make auxiliary tools for the installation and correction of the ring furnace support rollers. The auxiliary tools include a channel steel base and angle steel legs. The width of the angle steel legs is 1 / 2 of the corresponding side length of the channel steel base, and the edges are aligned. The height of the angle steel legs is the same as the height of the channel steel base. Triangular grooves are engraved on the center lines of the horizontal and vertical directions on the upper surface of the channel steel base, and they intersect at a point in the center of the channel steel base. The length of the channel steel base is the same as the width of the corresponding support roller.

[0015] When using, such as Figure 4 , Figure 5 As shown, the auxiliary tool for installing and calibrating the ring furnace support roller is set up on the support roller. Ensuring that the length of the channel steel base is aligned with the thickness of the support roller at both ends, a 0.02mm / m strip level is used to adjust the horizontal and vertical directions to be horizontal. The resulting top center is the roller center. Before grouting the anchor bolts, plumb bobs are suspended from the four angle steel legs and aligned with the pre-selected center line on the ground. When the projection points of all four plumb bobs on the ground are on the center line, the first installation and calibration work before grouting is completed. After grouting the anchor bolts, a triangular prism is set up at the intersection of the triangular grooves at the top of the auxiliary tool for installing and calibrating the ring furnace support roller. A total station set up at the center is used for precise positioning according to the corresponding design drawings. After this calibration work is completed, the entire installation and calibration process of the ring furnace support roller is finished.
