Abstract
The utility model belongs to a production auxiliary apparatus in metallurgy industry, concretely a rolling-mill middle roller bearing box disassembly and assembly device, comprising a support rack, two support trolleys and an operation control console, characterized in that one lift-up hydraulic ram and one disassembly-assembly hydraulic ram are fixed on one support trolley and one lift-up hydraulic ram, one disassembly-assembly hydraulic ram and a flat-push hydraulic ram are fixed on another support trolley and a roller bracket in U shape is fixed on the support hydraulic ram. When separating, the middle roller bearing box is mounted on the U shaped bracket and the support ram supports the roller and then the bearing box is supported by the lift-up hydraulic ram and finally the middle roller is separated from the bearing box along the horizontal direction by the disassembly-assembly hydraulic ram and the flat-push hydraulic ram; when mounting, the middle roller is hung on the U shaped bracket and the bearing box is mounted on the lift-up hydraulic ram and then the bearing box and the middle roller are mounted at the same horizontal position by lifting the lift-up hydraulic ram.
Description
Technical field:
The utility model belongs to metallurgy industry production auxiliary equipment, is specifically related to milling train intermediate calender rolls bearing housing attaching/detaching apparatus.
Background technology:
When overhauling the intermediate calender rolls bearing housing of S6 type milling train, adopt the overhead traveling crane intermediate calender rolls bearing housing of slinging to dismantle or install, because the weight of bearing housing is heavier, in disassembly process, unbalance, the bad grasp of the depth of parallelism of roll and bearing housing is in unloading process, the impaired phenomenon of sealing between bearing and the bearing housing often takes place, and causes the spare part waste.
Summary of the invention:
The utility model aims to provide simple to operate, milling train intermediate calender rolls bearing housing attaching/detaching apparatus easy to use.
The realization the technical solution of the utility model is: comprise bracing frame, two support dollies, operating console, it is characterized in that being set with jack-up hydraulic ram and dismounting hydraulic jack on one of them support dolly, another supports on the dolly and is set with jack-up hydraulic ram, dismounting hydraulic jack and horizontal sliding hydraulic jack, be fixed with the support hydraulic pressure oil cylinder on the dismounting hydraulic jack, be fixed with roller bracket on the support hydraulic pressure oil cylinder, the roller bracket framework that takes the shape of the letter U.
Using method of the present utility model is: during separation, milling train intermediate calender rolls bearing housing is lifted on the U-shaped support of the present utility model, the support hydraulic pressure oil cylinder is propped up roll, by being arranged on the jack-up hydraulic ram that supports on the dolly bearing housing is held up then, intermediate calender rolls is separated with the bearing housing horizontal direction with the horizontal sliding hydraulic jack by the dismounting hydraulic cylinder at last; During installation, the milling train intermediate calender rolls is lifted on the U-shaped support of the present utility model, bearing housing is placed on the jack-up hydraulic ram, lifting by the jacking hydraulic cylinder makes bearing housing and intermediate calender rolls be in same horizontal level then, by dismounting hydraulic cylinder and horizontal sliding hydraulic jack intermediate calender rolls and bearing housing horizontal direction is assembled at last.
