Description
Technical field
The utility model relates to a kind of easy device that is widely used in various on-line replacing furnace roller bearing stoves, belongs to the mechanical maintenance tool in use technical field.
Background technology
When the furnace roller bearing maintain and replace of vertical annealing furnace, need furnace roller be dismantled, and then the furnace roller bearing is taken off from bearing block, repair or replace, not only increased man-hour greatly, also increased workload and labour intensity.On-the-spot in maintenance work; The maintenance personal hopes under the situation of not dismantling furnace roller, to carry out the dismounting of furnace roller bearing; But because the bearing chamber of furnace roller bearing and dependency structure project organization are complicated, do not have special-purpose dismantling device at present, be difficult to realize on-line replacing furnace roller bearing.
The utility model content
The utility model problem to be solved provides a kind of under the situation of not dismantling furnace roller, can carry out the device of the on-line replacing furnace roller bearing of furnace roller bearing replacing.
The technical scheme that solves the problems of the technologies described above is:
A kind of device of on-line replacing furnace roller bearing; It is made up of bracing frame, fore side suspension rod, transmission side suspension rod; Fore side suspension rod, transmission side suspension rod are connected with fore side axle head, the transmission side axle head of furnace roller axle respectively; Bracing frame is placed on fore side axle head, the transmission side axle head below of furnace roller axle, and the upper surface of bracing frame contacts with the fore side axle head of furnace roller axle, the lower surface of transmission side axle head.
The device of above-mentioned on-line replacing furnace roller bearing; One end of said fore side suspension rod is a ring flange; The circumference of ring flange has screw, on the end face of the fore side axle head of furnace roller axle, corresponding screw is arranged, and fastening bolt is locked at ring flange on the end face of fore side axle head of furnace roller axle.
The device of above-mentioned on-line replacing furnace roller bearing, an end of said transmission side suspension rod has axle sleeve, and the external diameter of the transmission side axle head of the internal diameter of axle sleeve and furnace roller axle is complementary, and the transmission side axle head of furnace roller axle is inserted in the axle sleeve.
The device of above-mentioned on-line replacing furnace roller bearing, the bottom of support frame as described above are screw jack, and the semicircle support ring is arranged at the top of bracing frame, the support ring opening up, the bottom of support ring is fixed on the swing arm of screw jack.
The usefulness of type of the present invention is: can under the situation of not dismantling furnace roller, can the furnace roller axle be sling through bracing frame, fore side suspension rod and transmission side suspension rod, from the furnace roller axle, the furnace roller bearing pulled down then, the furnace roller bearing is keeped in repair and changes.It is easy, easy and simple to handle, cheap that this device is made, and can effectively shorten replacing time, workload and the labour intensity of furnace roller bearing.
