Mechanical adjusting type centering wheel device for stepping type heating furnace bottom

Abstract

The invention provides a step-by-step heating furnace bottom mechanically adjustable centering wheel device capable of centering and adjusting the guide rail of the moving frame. It includes a centering wheel support and a centering wheel set installed in the wheel groove of the centering wheel support, wherein the centering wheel set includes a centering wheel and a centering wheel shaft passing through the centering wheel, and the centering A self-aligning roller bearing and a centering wheel bushing are installed between the wheel shaft and the centering wheel, and a bearing cover is installed on the end face of the bushing. The centering wheel shaft can drive the centering wheel to translate in the vertical axial direction along the elongated shaft hole. A pair of parallel adjusting screw rods are symmetrically installed on the outside of the centering wheel support. The rods are respectively connected to the two ends of the centering wheel shaft to adjust the translational distance of the centering wheel shaft in the elongated shaft hole. The device of the invention can realize the adjustment of the gap between the centering wheel and the centering guide rail, and can also adjust the verticality of the centering wheel shaft.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing, and in particular relates to a step-by-step heating furnace bottom mechanically adjustable centering wheel device which is applied in a steel plant and can perform centering adjustment on a guide rail of a moving frame. Background technique [0002] Most of the bottom machinery of the walking heating furnace in the steel plant adopts a lifting and translational double-layer steel structure frame, a ramp seat, and a double-supported roller structure on the upper and lower sides. The billet moves in the furnace through the movement of the fixed beam and the walking beam. . During the moving process of the lifting and translating frame, several sets of centering wheels are required to guide it to center and guide it, so as to prevent the deviation when the lifting and translating frame moves, that is, to avoid the steel billet on the moving beam supported by the translating frame from oc...

AI Technical Summary

Problems solved by technology

When it is necessary to adjust the gap between the centering wheel and the centering guide rail, the adjustment of the centering wheel support is difficult and troublesome, so in the actual operation process, the steel mills do not adjust the centering wheel gap at all

In this way, if the gap is too large, the effect of centering and guiding will become poor, and the billet will deviate; Internal stress, while running resistance will also increase
