Technical Field

The invention relates to the field of steelmaking equipment, in particular to a bottom pouring type steel ladle.

Background

The bottom pouring type steel ladle in the current steel making equipment is widely used, the traditional bottom pouring type steel ladle structure is that the bottom of the steel ladle is provided with a pouring gate, a sealing plate is arranged above the pouring gate, an operating mechanism installed outside the steel ladle drives the sealing plate to lift so as to complete pouring action, an operating rod of an operating mechanism of a general bottom pouring type steel ladle is arranged in a fixed direction, the field environment is different in the actual use process, and the operating rod in the fixed direction is inconvenient for the actual operation of workers.

Disclosure of Invention

The invention aims to solve the problem that an operating rod of an operating mechanism of the existing bottom pouring type steel ladle is fixedly arranged in one direction and is inconvenient for workers in actual operation, and provides the bottom pouring type steel ladle capable of being operated at any angle.

The specific scheme of the invention is as follows: a bottom pouring type steel ladle comprises a portal frame, wherein two ends of the portal frame are provided with vertically downward supporting plates, a steel ladle is arranged between the two supporting plates, the bottom of the steel ladle is provided with a pouring hole, a sealing plate is arranged above the pouring hole, the top of the sealing plate is connected with a set of lifting device, the lifting device comprises a supporting plate A fixed at the lower part of the outer wall of the steel ladle, a supporting plate B with a rectangular through hole in the middle is fixedly arranged on the steel ladle above the supporting plate A, a circular through hole is arranged in the middle of the supporting plate A, a lantern ring is arranged above the circular through hole, a vertical cylindrical ejector rod is arranged in the lantern ring, the bottom of the ejector rod penetrates through the circular through hole of the supporting plate A, a bracket is fixedly arranged on the outer wall of the lantern ring, the tail end of the bracket exceeds the top of the lantern ring by a certain distance and is hinged with an operating, the two sliding columns are just positioned on two sides of the ejector rod, the ejector rod is positioned on the upper surface of the sliding column and the lower surface of the sliding column and is respectively provided with a circular baffle, the diameter of the circular baffle is larger than the distance between the two sliding columns and smaller than the distance between the two branch supporting rods, the excircle of the top of the ejector rod is sleeved with a sliding rod matched with the rectangular through hole, the sliding rod penetrates through the rectangular through hole and the top of the supporting plate B and is provided with a horizontal supporting rod, the end part of the supporting rod is provided with a connecting rod extending downwards, the bottom of the connecting rod is connected with the sealing plate.

The working principle of the invention is as follows: the sealing plate is in a state of sealing the pouring hole in a normal state, when pouring is needed, the steel ladle is hung to a corresponding position, then a worker holds the tail of the operating rod and presses downwards, the middle of the operating rod is fixedly hinged on the support, so that the branch rod at the front end of the operating rod can swing upwards by taking a hinged point as a circle center, the sliding column at the end part of the branch rod drives the baffle plate positioned on the upper surface, the baffle plate drives the ejector rod, the ejector rod drives the sliding rod to move upwards, the sliding rod drives the sealing plate at the bottom of the connecting rod to lift upwards, the pouring hole is opened, and the sliding rod is locked by the locking bolt, so that; when the workman need change the action bars direction according to site environment, only need to use the ejector pin as centre of a circle level rotate the action bars can, through setting up the lantern ring, lantern ring outer wall fixed mounting support, the support is terminal articulated in the middle of with the action bars, and during the level rotated the action bars, the support also followed the rotation with the lantern ring, and two travelers are located the ejector pin both sides all the time to the realization can be in arbitrary angle operation.

Compared with the prior art, the invention has the following advantages: the operation angle can be adjusted according to the site environment by workers at will, the operation is convenient in actual use, and the safety of the workers is greatly improved.
