Abstract
A service stand integral with the rotary kiln carrying mechanism to facilitate field maintenance of the kiln roller supports and eliminate the danger inherent in field constructed blocking.
Claims7
In a supporting arrangement for a rotary kiln having an axis of rotation;
- a base;
- support roller means mounted for movement from a kiln supporting position to a retracted service position wherein said support roller means is not in engagement with the kiln;
- and,
- stationary support means in position to receive and support the kiln when said support roller means are moved out of supporting engagement with the kiln,
- said stationary supporting means includes a pedestal supported on said base in position to receive and support said kiln when said supporting roller means is retracted to a servicing position, said pedestal includes a pair of spaced apart upstanding members;
- a pad block receiving surface formed on each of said upstanding members constructed and arranged to provide adequate operating clearance for the rotary kiln when said kiln is supported by said supporting roller means;
- and
- pad block means insertable on each of the receiving surfaces formed on the upstanding members to provide supporting surfaces for the kiln which substantially increases the clearance distance between the pad block receiving surfaces and the kiln when said supporting roller means is in operating position.

In a supporting arrangement for a rotary kiln having an axis of rotation;
- a base;
- a pair of rotatable roller supports disposed transversely with respect to the axis about which the kiln rotates;
- a slide member for each of said rotatable roller supports, said slide members being mounted on said base in position to support said rotatable roller supports for movement there along in a direct transverse to the axis about which the kiln rotates into a kiln supporting position or to a retracted service position;
- a stationary support including a pair of upstanding pedestal members disposed equidistances apart on each side of a centerline which passes through the axis about which the kiln rotates;
- a pad block receiving surface formed on each of said pedestal members, said surfaces being constructed and arranged so as to provide adequate operating clearance for the rotary kiln when the kiln is operatively supported on said pair of rotatable roller supports;
- a pad block insertable on each of said pad block receiving surfaces formed on each of said upstanding pedestals, said pad blocks operating to provide a supporting surface for the kiln when said slide members are moved to retract said roller supports to a service position, said pad blocks being constructed and arranged to substantially increase the clearance distance between the receiving surfaces and the kiln;
- and,
- covers for each of said pad block receiving surfaces, said covers operating to protect said pad block receiving surfaces from an accumulation of dust and dirt when said pad blocks are not in position thereon.
