Description

Transfer flat car for overturning ladle hot repair

Technical Field

The invention relates to a hot-repair ladle, in particular to a transfer flat car for turning over ladle hot-repair.

Background

A steel ladle is used by workers to contain molten steel so as to carry out refining treatment and continuous casting pouring, and the steel ladle hot repair technology is basically characterized in that after inert gas (nitrogen) is connected with a steel ladle air brick, oxygen is used for blowing and cleaning steel slag at the end part of the air brick from the front end of the steel ladle.

At present, the steel ladle is lifted by matching the hook on the travelling crane with the hanging ring on the steel ladle, then the steel ladle is moved by matching the travelling crane with the hook, the peripheral surface of the steel ladle is close to one contact fixed point at the bottom, the steel ladle is continuously moved towards the fixed point, the steel ladle can be overturned towards the fixed point, an opening of the steel ladle faces towards a worker, and the worker begins to repair the steel ladle towards the opening.

The defects of the technology are as follows:

when the workman is controlling the driving to overturn the ladle, the control driving is higher to workman's technical requirement, if improper operation leads to ladle upset to pass the head easily, makes the opening of ladle not according to the position of predetermined orientation, and ladle opening angle need be adjusted, therefore the workman is comparatively difficult to ladle angle of adjustment's control.

Disclosure of Invention

The invention aims to provide a transfer flat car for turning over a ladle for hot repair, wherein a ladle is vertically placed on the transfer flat car, and then the ladle is turned over from a vertical state to a horizontal state, namely the ladle is turned over to a position where an opening faces a worker, so that the condition that the opening of the ladle does not face the worker according to a preset direction is avoided, the worker does not need to control the turning angle of the ladle, and the ladle is conveniently turned over by the worker for hot repair treatment.

In order to realize the purpose of the invention, the invention adopts the following technical scheme: transfer flatbed about upset ladle hot patching, including automobile body and ladle, the automobile body is equipped with wheel and sweep, the bottom surface of sweep is located to the wheel, the face on sweep ground dorsad is equipped with the heat preservation apron, the heat preservation apron is equipped with the through-hole, the sweep is divided into the district of standing and is put the thing district, the district of standing and put the both sides that the thing district located the heat preservation apron respectively, it is equipped with puts the thing bucket to put the thing district, the ladle is arranged in and is put the thing bucket, the workman stands in the district, with the hot repair instrument from the district of standing orientation of putting the thing district and pass the through-hole, carry out the hot repair in the ladle and handle, the heat.

The ladle outer peripheral face is equipped with connecting piece and holding ring, and the connecting piece can cooperate the couple to hoist the ladle, puts the thing district and still is equipped with the second motor, and the periphery side of ladle is located to the second motor, and the second motor has the telescopic locating lever, and when the ladle was arranged in and is put the thing bucket, the workman started the second motor, and the locating lever can remove to running through the holding ring, makes the ladle fix a position and puts in the thing bucket.

Put the thing district and still be equipped with first motor, first motor has rotatable rotation axis, the outer peripheral face of rotation axis with put the thing bucket towards the face fixed connection of heat preservation apron, arrange in the ladle and put the thing bucket after, the workman starts first motor, the rotation axis can rotate, puts the thing bucket and overturns towards heat preservation apron, makes the ladle be in horizontal state.

Preferably, put the thing district and be equipped with the third motor, the third motor has the telescopic ejector pin, and the end connection of ejector pin puts the face of thing bucket towards the sweep, places the thing bucket in at the ladle after, and the workman starts the third motor, and the ejector pin can move towards putting the thing bucket, makes the ladle be in horizontal state, further drives the upset of ladle, because the ladle is heavier, the ejector pin can play the supporting role to the ladle.

Preferably, the both sides of putting the thing bucket are equipped with slide mechanism, and slide mechanism includes spout and slider, and the shape of spout is the arc, and the spout has head end and tail end, and the slider removes in the spout, and the workman can remove the ladle from the vertical state upset to the period of horizontal state, and the slider can remove to the tail end from the head end of spout, because the ladle is heavier, and slider cooperation spout can play the supporting role to the ladle.

Preferably, the district of standing is equipped with the telescopic elevating platform, and the elevating platform can remove to the sweep dorsad, through adjusting the height of elevating platform apart from the sweep, is applicable to the workman that need not be high.

Compared with the prior art, the transfer flat car for overturning ladle hot repair has the following beneficial effects that:

the transfer flat car for overturning ladle hot repair can lift a ladle by matching with a hook through a connecting piece, then place the ladle in a storage barrel, and at the moment, the ladle is in a vertical state, and an opening is upward;

secondly, the workman stands in the district of standing, puts the thing district with the heat repair instrument from the district of standing towards and passes the through-hole, carries out the heat repair in to the ladle and handles, and the opening of the ladle of transverse state is towards the workman, can prevent through the heat preservation apron that the workman is scalded by the steam that gives off in the ladle.
