Self-adaptive triple sphere supporting device of large-scaled slide shoe tube mill

Abstract

The invention relates to a supporting device of a large-scaled mill used in grinding of building materials and mines, in particular to a self-adaptive triple sphere supporting device of a large-scaled slide shoe tube mill. The device comprises a foundation plate and a slide shoe supporting group, wherein the foundation plate is provided with a supporting body consisting of a pair of concave and convex sphere supporting bases which are mutually matched, and the slide shoe supporting group is arranged on the supporting body; and the slide shoe supporting group consists of a supporting base bodyand two slide shoe tiles arranged on the supporting base body, and each slide shoe tile consists of a slide shoe tile body and a pair of concave and convex sphere tile bases which are mutually matched and support the slide shoe tile body. In the supporting device, by the adjusting actions of multiple spherical surfaces, changes, which are caused by deformation of a cylinder body and changes of a grinding body and materials when the mill rotates, of all working condition loads are self-adapted; the assembly of the supporting device is easy, and the common single-side four slide shoe tiles are unnecessarily pre-loaded by helix or hydraulic pressure, and the load allocation of the common single-side four slide shoe tiles are unnecessarily adjusted in operation; and the assembling efficiency is greatly improved, and the maintenance work of the operating mill is reduced.

Description

Technical field: [0001] The invention relates to a supporting device for a large mill used for grinding of building materials and mines, in particular to a self-adaptive three-sphere supporting device for a large sliding shoe tube mill. Background technique: [0002] At present, the support device of large tube mills usually adopts a structure with two supports on one side or four supports on one side, while the support structure with four sliding shoes on one side is usually two outer sliding shoe spherical supports, and two inner sliding shoe screw or hydraulic adjustment supports, which is troublesome to install; CN201006447Y, which has been announced by the Patent Office of the State Intellectual Property Office, uses an asymmetrical sliding support device. The load of the sliding shoes is estimated, and the bearing capacity of the support cannot be reasonably distributed in actual use. It needs frequent adjustments, often It causes uneven wear of the sliding shoe bearin...
