The technical scheme adopted by the utility model is as follows: the utility model provides a WZL type reel shaft coupling baffle fixing device, includes axle head baffle and spindle nose terminal surface, the axle head baffle is fixed on the spindle nose terminal surface through 4 first fixing bolt, still includes second fixing bolt, bolted connection frame, the axle head baffle intermediate position is provided with 2 at least through-holes, with be provided with on the spindle nose terminal surface of axle head baffle complex with the screw that corresponds with the through-hole, the second fixing bolt with through-hole, screw match, bolted connection frame includes connecting rod, bolt cover and third fixing bolt, the bolt cover matches with the nut of first fixing bolt, and every first fixing bolt cover is established a bolt cover, has the connecting rod to connect between two adjacent bolt covers, threaded through-hole has been seted up to bolt cover one side, the third fixing bolt set up in threaded through-hole, the bolt cover is furnished with at least one third fixing bolt;
further, the first fixing bolt is an outer hexagon bolt;
further, a groove matched with the third fixing bolt is formed in the side face of the nut of the first fixing bolt;
further, each bolt is sleeved with two third fixing bolts, and the two third fixing bolts are oppositely arranged.
The second fixing bolt is arranged in the middle of the shaft end baffle to strengthen the connection between the shaft end baffle and the end face of the shaft head, so that the shaft end baffle cannot easily fall off, and the safety of equipment is enhanced; the arrangement of the bolt connecting frame enables the original 4 first fixing bolts to be connected into a whole by the bolt connecting frame after the shaft end baffle is connected and fixed with the end face of the shaft head, so that the bolt connecting frame is not easy to loosen or break, and the online service time is prolonged. Before improvement, the maintenance is carried out once in 3 months, the single maintenance time is at least 4 hours, after improvement, the maintenance time interval is changed to 12 months, and no abnormality is found in the period.
The utility model has simple structure and convenient installation and use, can prolong the online use time of the WZL type reel coupler, reduces the overhaul times, saves the cost, reduces the labor intensity and improves the production efficiency.
