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

Abstract

The invention provides a mechanical adjusting centering wheel device for a stepping type heating furnace bottom. The mechanical adjusting centering wheel device can achieve centering adjusting of a lead rail of a moving frame. The mechanical adjusting centering wheel device for the stepping type heating furnace bottom comprises a centering wheel support saddle, a centering wheel set installed in a wheel groove of the centering wheel support saddle, wherein the centering wheel set comprises a centering wheel and a centering wheel shaft which passes through the centering wheel; a centre regulating roller bearing and a centering wheel shaft sleeve are arranged between the centering wheel shaft and the centering wheel, and a bearing press cover is arranged on the end face of the shaft sleeve; long shaft holes for penetrating through the centering wheel shaft are arranged at two sides of the wheel groove of the centering wheel support saddle; the centering wheel can be driven to upwards levelly transmit along the long shaft hole in the vertical axial direction through the centering wheel shaft; and a pair of parallel adjusting lead screws are symmetrically arranged outside the centering wheel support saddle, and are respectively connected to two ends of the centering wheel shaft; and the adjusting lead screws are used for adjusting the level moving distance of the centering wheel shaft in the long shaft hole. With adoption of the mechanical adjusting centering wheel device for the stepping type heating furnace bottom, clearance between the centering wheel and a centering lead rail can be adjusted, and verticality of the centering wheel shaft also can be adjusted.

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...
