Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the following embodiments of the present utility model will be described in further detail with reference to the accompanying drawings.
It should be noted that, in the embodiments of the present utility model, all the expressions "first" and "second" are used to distinguish two entities with the same name but different entities or different parameters, and it is noted that the "first" and "second" are only used for convenience of expression, and should not be construed as limiting the embodiments of the present utility model, and the following embodiments are not described one by one.
Fig. 1 shows an embodiment of a steel ladle ear sleeve according to the utility model comprising an ear sleeve 1, said ear sleeve 1 being an internally hollow cylinder and having at least one wedge-shaped slot 4; the locking clamp 2 is of a circular ring structure, and locking fixing blocks 5 which axially extend out along the circular ring structure and are in one-to-one correspondence with the wedge-shaped notches 4 on the ear shaft sleeve are arranged; the lug shaft sleeve 1 is detachably sleeved outside the trunnion 3 through the locking clamp 2.
Fig. 2 shows a schematic installation of a ladle collar 1 according to the utility model, said collar 1 being mounted on a ladle trunnion 3.
The trunnion sleeve 1 is provided with at least one wedge-shaped slot 4, preferably two, the connection of the two wedge-shaped slots 4 being at the diameter of the cross section of the trunnion sleeve 1. The locking clamp 2 is provided with locking fixing blocks 5 which are in one-to-one correspondence with the wedge-shaped notches 4 on the ear shaft sleeve 1. During the use, through wedge notch 4 and locking fixed block 5's fixed connection, with the fixed ear cup 1 of locking clamp 2, prevent that ear cup 1 from rotating on trunnion 3.
The fit of the trunnion 3 and the trunnion sleeve 1 is changed from the interference fit of the prior art to a clearance fit, but without changing the dimensions of the trunnion 3. Less impact on the trunnion 3 already in use, and no need to custom-tailor the trunnion 3 specifically for the present solution, without additional cost.
