Abstract

The utility model relates to a furnace roller maintenance device, in particular to a maintenance auxiliary device for a furnace roller bearing. A device for disassembling the furnace roller bearing comprises a ring main body, a rear baffle plate and a plurality of screws, wherein the ring main body comprises an upper half circle part and a lower half circle part, two sides of the upper half circle and the lower half circle are fixedly connected by bolts, and the ring main body is provided with a plurality of threaded holes along the circumference; the rear baffle plate is circular and is provided with a plurality of threaded holes corresponding to the threaded holes on the ring main body along the circumference; and the screws sequentially penetrate through the rear baffle plate and the ring main body from the threaded holes of the rear baffle plate and are fixed with the rear baffle plate through nuts and bolts. The device for disassembling the furnace roller bearing effectively improves the work efficiency for disassembling the furnace roller bearing and reduces the work intensity.

Description

A kind of furnace roller bearing disassembling device
Technical field
The utility model relates to the furnace roller maintenance unit, relates in particular to a kind of furnace roller bearing maintenance servicing unit.
Background technology
Roll and to occur dross and furnace roller damage etc. in the furnace roller use and all need furnace roller is changed, it is the critical process that the time is the longest in the furnace roller replacing process, labour intensity is maximum that furnace roller is changed bearing removal, and it is all many that each furnace roller is changed quantity, adopt traditional method for dismounting, every furnace roller bearing is removed and is generally all needed 4-8 hour, removal tool all adopts traditional sledgehammer, crowbar, spanner and hydraulic pressure to draw horse, the instrument that needs is many, fragile bearing and instrument, efficient is low, and labour intensity is big.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of furnace roller bearing disassembling device is provided.The utility model has effectively improved the operating efficiency of furnace roller bearing removal, has reduced labour intensity.
The utility model is achieved in that a kind of furnace roller bearing disassembling device, it is characterized in that it comprises:
The annulus body, it comprises two semi-circular portions up and down, and the both sides of last lower half circle are bolted to connection together, and the annulus body is provided with some screwed holes along circumference;
A backboard, it is a plectane, is provided with screwed hole corresponding on some and the annulus body along circumference;
Some screw rods, it passes backboard and annulus body successively from the screwed hole of backboard, and it is fixed with nut bolt and backboard.
Described roller bearing provision for disengagement, it also comprises a hydraulic jack, it is arranged between the described screw rod.
The utility model draws and unloads before the bearing, should pressurize to axle the inside oiling with the oil filler point of hydraulic jack by the furnace roller axial end earlier, makes hydraulic oil be full of the oil groove on axle surface, thereby makes the surperficial gap that produces of bearing inner sleeve and axle.More laborsaving when being convenient to dismantle like this, simultaneously also can protect bearing, it is excessive and draw bad bearing to be difficult for Yin Lali.Following remarkable advantage is compared with prior art arranged: the dismounting time that has significantly reduced the furnace roller bearing; Obviously reduced maintenance worker's labour intensity; Can reduce the cost of overhaul to a certain extent.
Description of drawings
Below, in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, a kind of furnace roller bearing disassembling device, it comprises:
Annulus body 1, it comprises two semi-circular portions up and down, and the both sides of last lower half circle are fixed together by bolt spiral shell 5,7 mothers, and the annulus body is provided with some screwed holes along circumference;
A backboard 2, it is a plectane, is provided with screwed hole corresponding on some and the annulus body along circumference;
Some screw rods 3, it passes backboard and annulus body successively from the screwed hole of backboard, and it is fixing with nut bolt 4,6 and backboard 2.
Described roller bearing provision for disengagement, it also comprises a hydraulic jack, it is arranged between the described screw rod 3 and (fails among the figure to show).
