Description
Technical Field
The utility model relates to a metallurgical jar auxiliary assembly field especially relates to molten steel jar tilting mechanism, concretely relates to molten steel jar tilting mechanism's pull rod.
Background
The ladle tilting mechanism, also called ladle tilting mechanism, is structurally shown in fig. 1, and mainly comprises a hanging bracket 1 and a pull rod 2, wherein the hanging bracket 1 is arranged on the side part of a ladle 3, one end of the pull rod 2 is hinged with a hinged seat at the bottom of the ladle 3, and the other end of the pull rod is hinged with the hanging bracket 1. When the molten steel tank is used for casting, molten steel flows out from a discharge hole at the bottom of the molten steel tank and flows in through a feed inlet at the top of the intermediate tank, and in the process, the pull rod is influenced by the intermediate tank on heat radiation of the pull rod, so that deformation is generated to influence the action of a tilting mechanism, and the pull rod needs to be frequently replaced to influence production.
SUMMERY OF THE UTILITY MODEL
The utility model provides a pull rod of ladle tilting mechanism, its pull rod that can solve current ladle tilting mechanism is influenced by heat radiation, needs often to change, influences the technical problem of production.
The technical scheme is that, a pull rod of ladle tilting mechanism, the pull rod includes the body, its characterized in that: the heat insulation protective shell is embedded in the protective shell, and a slit which extends in the length direction and penetrates through the two ends of the protective shell is formed in the middle of the upper end face of the protective shell;
the positioning device is characterized in that one end of the top of the body is upwards convexly provided with a circular positioning column, the other end of the top of the body is upwards convexly provided with a waist-shaped positioning column, the inner side walls of the two slotted ends are symmetrically provided with positioning grooves, the two positioning grooves are spliced to form waist-shaped positioning holes, and the circular positioning column and the waist-shaped positioning column are respectively installed in the waist-shaped positioning holes.
Further, the heat insulating lining is compressed and attached to the body.
Furthermore, spring pressing plates are arranged at the two ends and the middle part of the protective shell, and the spring pressing plates surround the periphery of the protective shell and are provided with openings opposite to the slits.
Furthermore, both ends of the slot are respectively provided with a notch.
Further, the cross section of the body is rectangular.
Furthermore, the molten steel tank tilting mechanism comprises a hanging frame, the hanging frame is arranged on the side portion of the molten steel tank, a hinge seat is arranged at the bottom of the molten steel tank, the hinge portion of the hanging frame and the hinge portion of the hinge seat are respectively inserted into the gap between the adjacent support lugs at the two ends of the body and are locked through pin bolts and nuts, and the heads of the pin bolts and the nuts are arranged in the counter bores.
The pull rod of the steel ladle tilting mechanism of the utility model reduces the influence of the heat radiation of the intermediate tank and reduces the replacement frequency by arranging the protective shell with the embedded heat insulation lining outside the body of the pull rod; simultaneously, the protective housing adopts the mode of holding tightly to set up outside the body of pull rod, and the protective housing is equipped with and extends and the both ends are run through and crack, and when needs are changed, only need to push into new protective housing along the body, and corresponding articulated portion stretches out from cracking and avoids interfering, and old protective housing is ejecting along the body under the top push effect of new protection, accomplishes the change of protective housing, and it is more convenient not only to change, can effectively shorten the change time moreover.
