The molten iron ladle is widely used in the casting industry; After receiving molten iron in front of the furnace, it is transported to the mold by crane for pouring. The molten iron ladle is mainly composed of 6 parts

I. The hanger assembly

is composed of three parts, namely, the hanger, beam and hanger (hook). Lifting device: the lifting device on the top of the ladle. The safety factor of its design is greater than the national machinery industry standard, and the crane produced by our company. Q235-A round steel with less than 5 tons, and

with more than 10 tons are multi-layer steel plate overlapping combination. Flaw detection shall be conducted for each layer of steel plate and NDT report shall be issued to ensure safe and reliable use. The center of gravity of the ductile iron ladle is offset due to the reason that the reduction box is on one side. In order to ensure the smooth pouring, the method to solve the center of gravity offset is to reasonably calculate the center of gravity position of all factors acting on the beam during the operation of the ladle, that is, the center of gravity position of the lifting and climbing

Cross beam: it is the connecting beam of the lifting rod and the lifting rod, and its material is channel steel or steel plate welding, and the appropriate form is selected according to the bearing capacity. Ensure that the safety factor of the design is greater than the national machinery industry standard

suspender: Q235-A carbon structural steel, all plates are from regular manufacturers, and double guarantee is realized for materials. Our company adopts multi-layer steel plate combination splicing for the casting ladle suspender of more than 5 tons, and its production process is as follows: CNC unified blanking to reduce the longitudinal stress of the material, NDT for each layer of steel plate, 60 ° full welding for the groove on both sides of the two welded suspenders, to ensure that the weld is free of sand holes, air holes and cracks. This structure is better than the forging as a whole: it avoids the stress existing in the forging, the material of the forging is difficult to guarantee, and some defects of the

multi-layer plate welding do not affect the normal use of the equipment, while the forging can have serious problems. Therefore, under normal working conditions, there is no problem with the use of splicing suspender, and the safety of use is also higher than that of forged parts (which can be found outside before damage). This form is also accepted by most manufacturers

II. Safety device

The safety card, namely the fork type safety device, is set at the position of the ladle bar. During the lifting process of the ladle, the safety card must be clamped on the suspender to ensure the safety during the lifting process, to avoid the relative movement of the gearbox and the ladle due to the inertia force during the lifting process of the ladle, so that the final self-locking worm gear is protected. Therefore, the safety card has two functions: the first is to protect the self-locking transmission mechanism in the gearbox. The second is to protect the smooth transportation of the ladle and prevent the pouring of molten iron

III. The can body

is made of Q235-A carbon structural steel, and the plates are all from the regular manufacturers, realizing double guarantee for the materials. The can body shall be uniformly cut by CNC, the weld shall be inspected, and the NDT report shall be provided. No defect affecting the strength is allowed. The position of the wrapped shaft is reasonably designed and calculated to ensure safety. Perforations are drilled on the barrel body to facilitate the drying of the bag after laying

IV. The bearing capacity of the transmission part of the reducer

is designed according to the maximum tilting moment (tilting hanger part). Because the tilting moment of the hanger is greater than the working moment, it is safer and more reliable. The reducer produced by our company has the following structural forms

First, the 5-ton ductile iron ladle reduction mechanism is a two-stage drive, the first-stage bevel gear and the first-stage worm gear pair drive, and the 10-ton ductile iron ladle reduction mechanism is also a two-stage drive, which is a two-stage worm gear pair drive, and the last stage worm gear pair has self-locking stop

Second, the 15-30t ductile iron ladle reduction mechanism is a three-stage drive, the first stage sprocket and the second stage worm gear are driven by eight pairs, and the last stage worm gear pair has self-locking brake

V. The electric part

is driven by the motor and sprocket or pulley. The products produced by our company with the weight of less than 30 tons are driven by the sprocket and those with the weight of more than 30 tons are driven by the pulley. Customers can also select sprocket or pulley according to their own needs, which is convenient and flexible to operate and adjust

VI. The clutch part

consists of two-way clutch sleeve, positioning seat, positioning handle, etc. Working principle: the two-way clutch sleeve is equipped with clutch jaws on both sides, which can move axially on the handwheel shaft, move the jaws forward to connect with the pulley or sprocket base, and position them on the handwheel shaft through the positioning handle. In this way, the electric transmission line is transmitted to the pulley or sprocket seat by the motor, and is connected to the clutch through the base. Because the sliding clutch is positioned with the shaft, it is transmitted to the reducer. The end of the hand wheel shaft is a hand wheel. The hand wheel is sleeved on the hand wheel shaft through a copper sleeve, and the clutch is moved backward. After the clutch is disengaged from the electric clutch, it is pinched by the claw at the other end and the claw of the hand wheel, and the positioning handle of the clutch is positioned on the hand wheel shaft, so that the hand wheel and the hand wheel shaft can be connected through the clutch.
