Description

Special lifting appliance for tundish turbulator Technical Field The utility model relates to the technical field of turbulator installation, in particular to a special lifting appliance for a tundish turbulator. Background The tundish turbulator is a device installed in the tundish injection zone of the steelmaking reactor. The flow velocity of molten steel can be effectively weakened, turbulence is limited in the molten steel, and the laminar flow proportion of other areas of the tundish is increased, so that the molten steel flows more stably. Because there is not the couple that is used for lifting device to hang on the middle package turbulator, all need the people to use the steel wire to wrap the outside of turbulator earlier and make a steel wire structure that is used for the couple to hang when handling the turbulator at every turn, it is more troublesome when installing and dismantling, consequently, to above current situation, urgent need develop one kind can be connected with the turbulator fast and separate, be convenient for handling the turbulator, the special lifting appliance of middle package turbulator of facilitate the use, in order to overcome the not enough in the current practical application, satisfy current demand. Disclosure of utility model The utility model aims to provide a special lifting appliance for a tundish turbulator, which aims to solve the problems in the background technology. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a special hoist of middle package turbulator, includes base plate, pull rod, rings, interior tight mechanism and actuating mechanism that pushes up, four apex angles departments of base plate all are fixed with a pull rod, the upper end and the rings of pull rod are fixed mutually, the downside equipartition of base plate has four interior tight mechanisms that pushes up, install on the base plate and be used for driving four interior tight mechanism synchronous pivoted actuating mechanism that pushes up, interior tight mechanism includes lead screw, thread bush, extension bar, first tight board that pushes up, dead lever, second tight board that pushes up, sliding sleeve, bracing piece and first bevel gear, the lead screw rotates to be connected in the downside of base plate, install the thread bush on the lead screw, the thread bush is fixed mutually through two extension bars and first tight board that pushes up, the downside of lead screw is fixed mutually through dead lever and second tight board that pushes up, the second tight board that pushes up is located under the first tight board that pushes up, the upside of thread bush is fixed with the sliding sleeve, sliding sleeve slidable mounting is on the bracing piece, the bracing piece is fixed in the downside of base plate, the tip of first bevel gear that pushes up has the switch module, install on the lead screw. Preferably, the driving mechanism comprises a motor and a second bevel gear, wherein the motor is fixed on the base plate, the second bevel gear is fixed on an output shaft of the motor, and the first bevel gear is meshed with the second bevel gear. Preferably, the power module is electrically connected with the motor through a wire, and the motor is electrically connected with the switch button through a wire. Preferably, the base plate, the pull rod and the hanging ring are all made of stainless steel. The special lifting appliance for the tundish turbulator has the beneficial effects that when the special lifting appliance is used, the inner tightening mechanism is inserted into the turbulator, then the motor drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, the first bevel gear drives the screw rod to rotate, the screw rod rotates to drive the screw sleeve to move, the screw sleeve drives the first tightening plate and the second tightening plate to move outwards, the first tightening plate and the second tightening plate are tightened to the inner wall of the turbulator, and then the hook of the external lifting mechanism is hooked on the lifting ring to lift the turbulator. In conclusion, the utility model can be quickly connected with and separated from the turbulator, is convenient for lifting the turbulator and is convenient for use.
