Abstract
The utility model relates to a position adjusting device for a rolling mill transmission shaft cross bag connecting flange. The position adjusting device is used for disassembling and replacing a flat head. The position adjusting device is mainly composed of two sealed locking rings arranged in parallel, and two adjusting fixing threaded rods. Each locking ring is composed of an upper semi-circular ring body and a lower semi-circular ring body which are mutually abutted against through a locking bolt. A lug is connected on each upper semi-circular ring body and each lower semi-circular ring body. A hole is formed in each lug and used for enabling a single adjusting fixing threaded rod to penetrate through. The two adjusting fixing threaded rods are mutually parallel in a vertical mode. After the two semi-circular ring bodies of each locking ring are combined, the two lugs are distributed along the circumference with 90 degrees. The flat head of a transmission shaft can be conveniently replaced. Overhaul labor intensity of maintaining workers is reduced. Breakdown time is reduced.
Description
Technical field
The utility model relates to the cold rolling mill drive shaft connection arrangement, is specifically related to a kind of field stripping and erecting device for cold rolling mill transmission shaft cross bag ring flange interconnection system homalocephalus.
Background technology
What most cold rolling sour milling train group rolling mill transmission systems used is cross bag spline universal drive shaft, the installation site schematic diagram is as shown in Figure 1 in frame for cross bag adpting flange, power transmission shaft and homalocephalus: an end of spline power transmission shaft 2 is connected with gear-box by gear-box link cross bag adpting flange 1, and the other end of power transmission shaft 2 passes through homalocephalus link cross bag adpting flange 3 connection homalocephalus 4; Two homalocephalus 4 are set up in parallel up and down on two power transmission shafts 2, in the outside of two power transmission shafts 2, an intermediate roll shifting device 5 are set respectively.In said structure, cross bag adpting flange and homalocephalus Main Function are transmitting torques between gear-box and working roll, homalocephalus and power transmission shaft link together by the tooth-like ring flange of end face, homalocephalus internal gear tooth bar mechanism drives the flower cap with the position locking of working roll spindle nose, can realize that splined driveshaft synchronizes axial float with working roll.yet, due to power transmission shaft place cross bag adpting flange can " on, under, left, right " freely swing, and need power transmission shaft and cross bag adpting flange are sling simultaneously in homalocephalus dismounting and installation process, and guarantee that power transmission shaft and cross bag adpting flange are on same level, could smoothly the dismounting of damage homalocephalus or new homalocephalus be in place, but because operating environment greasy dirt in rolling-mill housing is more, narrow space, cross bag place is not easy to hang island chain adjustment, homalocephalus of each replacing needs 6 hours, have a strong impact on the unit rhythm of production, and waste a large amount of manpowers, material resources, bring larger potential safety hazard for simultaneously surfaceman's upkeep operation.
During dismounting, the connection layout of transmission shaft cross bag ring flange and homalocephalus as shown in Figure 2.Working roll spindle nose 7 is connected on homalocephalus 6, and power transmission shaft 9 is connected with homalocephalus 6 by cross bag adpting flange 2; The ring flange of cross bag adpting flange 2 and homalocephalus 6 end-tooth 8 places are that the double threaded screw 5 with 16 M20 is connected and fixed, and need to power transmission shaft and cross bag ring flange be sling with island chain before dismounting homalocephalus 6, guarantee level.Because cross Bao Chu position is less, double threaded screw 5 can not disassemble in the homalocephalus unloading process, to slowly extract frame out with the homalocephalus 6 of connecting screw rod 5 after can only pulling down cross bag section lock nut 3, one end of double threaded screw 5 first need to be installed on homalocephalus 6 when returning dress, then homalocephalus 6 is slowly sent in frame.if power transmission shaft in dismounting or installation process, cross bag mounting flange and homalocephalus 6 longitudinal center lines do not overlap, connect double threaded screw on homalocephalus and just can not throw off smoothly or insert transmission shaft cross bag mounting flange screw, cause power transmission shaft to move axially and spline is pulled open or closure, and can only adjust on cross bag ring flange by island chain, the deviation of lower direction (see cross bag ring flange sling steel wire rope 4 and the power transmission shaft steel wire rope 1 of slinging), can not adjust the homalocephalus entrance, the deviation of Way out, and cross bag ring flange place island chain is installed and is adjusted limited space, be not easy to adjust cross bag adpting flange 2 and make itself and homalocephalus 6 deads in line, adjust entrance this moment, need to complete in outlet and entrance side extension island chain during the Way out deviation, draw in adjustment process and put island chain the homalocephalus screw rod is alignd with cross bag flange connecting screw hole, maintenance worker's labour intensity and downtime have also greatly been increased.
