Abstract
The utility model relates to a fixing device of a tundish stopper rod lead screw. The fixing device of the tundish stopper rod lead screw is characterized by comprising a concave spherical surface lead screw sleeve (2), a convex spherical surface steering sleeve (3), a connecting rod (4), a connecting rod fixing plate (5) and a fastening bolt (6), wherein the concave spherical surface lead screw sleeve (2) and the convex spherical surface steering sleeve (3) are sleeved on a stopper rod lead screw (7) in a penetrating mode, one end of the concave spherical surface lead screw sleeve (2) is welded on the connecting rod (4), and the other end of the connecting rod (4) is sleeved inside the connecting rod fixing plate (5) in a penetrating mode and fixed through the fastening bolt (6). The fixing device of the tundish stopper rod lead screw is simple in manufacturing process, low in operational technical requirement, capable of reducing labor intensity of fastening a stopper rod, capable of effectively fixing and limiting the movement amount of the stopper rod by controlling of the stopper rod lead screw, strong in practicability, and feasible, easy and convenient to disassemble, assemble, combine and operate.
Description
Technical field
The utility model belongs to the smelting iron and steel technical field, relates in particular to a kind of
Tundish stopper screw rod fixture.
Background technology
In the tundish use, if control stream stopper
Screw mandrelCan't be fixed effectively and be used and occur stopper easily and take off problems such as rod, stopper be crooked from the tundish transverse arm, thereby make casting stream uncontrollable, cause single current to stop watering, mold liquid level goes up, overflow steel, damage equipment, upset rhythm of production, increase unnecessary consequences such as cost.
Summary of the invention
The purpose of this utility model is improved at the problem that exists in the background technology, and tundish stopper screw rod fixture a kind of easy and simple to handle, more directly perceived, more stable is provided.Technical solutions of the utility model are as follows: the utility model includes concave spherical surface screw mandrel cover, protruding sphere turning sleeve, connecting rod, connecting rod fixed head and fastening bolt; Concave spherical surface screw mandrel cover and protruding sphere turning sleeve are through on the stopper screw rod, and an end of concave spherical surface screw mandrel cover is welded on the connecting rod, and the other end of connecting rod is set in the connecting rod fixed head and with fastening bolt and fixes.The movement of stopper screw rod will be restricted like this, and top to bottom, left and right, front and rear all will be subjected to hoisting mechanism and effective control of the present invention, simultaneously, the existence of protruding sphere turning sleeve be arranged, even deviation appears in screw mandrel in installation process, also can adjust by turning sleeve.The top of said stopper screw rod is provided with the cutting face and is conducive to tight rod, reduces the tight rod time.
The utlity model has following advantage: manufacture craft is simple, and operating technology requires low; Reduce the labour intensity of tight rod; Fix and limit the amount of movement of stopper effectively by the control stopper screw rod; Practical, dismounting, combination, easy and simple to handle feasible.
