Technical field
The utility model relates to a kind of main iron hook operculum colpi.
Background technology
The blast-melted outflow from iron notch then discharges out of the furnace through main iron hook, has volume of smoke to produce in the blast furnace casting process.Be dedusting before the solution iron, generally the dedusting sealing cover be set at present,, operculum colpi (generally will be called the A lid near iron mouth place operculum colpi, and be called B lid, C lid outward successively) is set on main iron hook also simultaneously for guaranteeing good dust removing effects on the main iron hook side.On big-and-middle-sized blast furnace, near the iron mouth, lid-moving machine is set usually, utilize lid-moving machine that the A lid is removed before the blast furnace casting, after accomplishing, tapping outlet utilize lid-moving machine that the A lid is retracted again, and complex operation acquires a certain degree of difficulty and is consuming time more.In addition; On medium and small blast furnace, receive limitation in height between casting house platform and the tuyere platform, generally there are not enough spaces that lid-moving machine and A lid are set; Owing to the iron mouth with near outside tap drain is directly exposed near the iron mouth; Dust removing effects is poor when causing blast furnace casting, and flue dust overflows, and has influenced the casting house environment greatly.
The utility model content
The purpose of the utility model is in a kind of portable main iron hook operculum colpi of arranging and operating be convenient to is provided.
To achieve these goals; Adopt following technical scheme: a kind of portable main iron hook operculum colpi; Comprise operculum colpi, it is characterized in that: the down either side setting of said operculum colpi has the travelling car of wheel, and travelling car is provided with the brace table that supports operculum colpi; The main iron hook both sides have the track of the wheel walking of buying car in installments, and travelling car is through the motion of drive unit driving trolley.
Influence trolley travelling as further optimization in orbit in order to prevent that the splash scum from adhering to, said track is provided with shifting board near main iron hook one side.
As further optimization, for the molten iron that prevents overflow burns out track, said shifting board is provided with refractory masses near main iron hook one side.
Said shifting board extends upward earlier, tilts to the direction away from main iron hook one side then.
Said drive unit comprises motor and the step-down gear that is arranged at the travelling car outside; Cylinder connects with step-down gear; Wireline one end is connected with travelling car, walk around cylinder then successively and be fixed on the pulley on the iron notch platform, pulley with the wireline break-in after the other end link to each other with travelling car.
State drive unit and comprise motor and the step-down gear that is installed on the travelling car, the direct drive wheels of motor and step-down gear forms one from walking mechanism.
The utility model has been cancelled original lid-moving machine, and is simple in structure, easy to maintenance, and it is few to take the casting house platform space, is convenient to simplify casting house platform and tuyere platform and arranges.Simultaneously the utility model height is low, is applicable to each rank blast furnace, is particularly useful for the medium and small blast furnace that overhead clearance little or tap drain top in iron mouth top is not provided with tuyere platform; After adopting this device; The tap drain top obtains sealing basically, helps to improve dust removing effects, improves the casting house environment.
