Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminum electrolysis and aluminum processing technical field, concretely relates to a kind of hanging mechanism of correctable multi-dimension deviation of hoisting high-temperature aluminium liquid table package. BACKGROUND

[0002] In the aluminum electrolysis production process, the molten aluminum liquid produced by the electrolytic cell is in a molten state at a temperature above 900℃, and is loaded into a special aluminum liquid table package. The aluminum liquid table package is transferred to the casting and alloy processing workshop by a factory transport vehicle, and the aluminum liquid is handed over to the next process for production.

[0003] The schematic diagram of the aluminum liquid table package is shown in Fig. 1-2 During the transfer process of the aluminum liquid table package, the transfer and dumping mechanism between the transport vehicle and the transfer process will inevitably occur according to the layout and terrain of each factory. The aluminum liquid table package can generally load more than ten tons of aluminum liquid, and the self-weight of the table package also has more than ten tons. The total weight of the full load table package can reach about 30 tons or more. The transfer and handover link generally adopts a hoisting mode, i.e., when the transport vehicle transports the table package to a certain handover point, the hoisting equipment on the upper part of the point hoists the table package and transfers it to another transfer vehicle or equipment. The schematic diagram of the traditional hoisting table package is shown in Fig. 3 Due to the parking position of the transport vehicle, the placement angle of the previous handover point, etc., it is impossible to be very accurate, which causes the hoisting equipment to be inclined when hanging the hoisted table package, and the table package is also deviated and misaligned after transfer, etc., which makes the table package not flat and the angle incorrect, and in severe cases, it can cause the table package to tip over and fall, and the high-temperature aluminum liquid to spill, etc. The frequently occurring deviation and misalignment phenomenon is shown in Fig. 4 (a)- Fig. 4 (e).

[0004] At present, when the above deviation and misalignment occur in the industry, the hook position and angle of the hoisting equipment are manually adjusted on site, and the table package is manually pushed and supported on the ground to adjust its azimuth angle to the correct position during hoisting and lowering. This manual adjustment method has many defects, such as the need for multiple slow lifting and lowering to slowly compare and explore, low operation efficiency, poor safety with personnel close to high-temperature table package, the need for manual operation at all transfer and handover links, and the occupation of a large amount of human resources. In some high-altitude and narrow places, personnel are difficult to operate close to the operation, and the Chinese invention patent with publication number CN115583186A discloses a new energy full-towed aluminum package transport vehicle and a transport method. The aluminum package is provided on the full-towed vehicle, which not only can greatly reduce the aluminum liquid transport cost and improve the aluminum liquid transport efficiency, but also can greatly reduce the floor space of the new energy full-towed aluminum package transport vehicle in the workshop, and can improve the safety during the aluminum liquid transport process, and has obvious energy-saving and emission-reducing advantages. However, it is completely different from the function of the utility model, which is used when hoisting the table package. The patent is used when transporting the table package on the vehicle. The utility model discloses a kind of hanging mechanisms for hoisting high-temperature aluminium liquid platform ladle, which can correct multi-dimensional deviation.

[0005] To solve the above problems, the utility model provides a hanging mechanism for hoisting high-temperature aluminium liquid platform ladle, which can correct multi-dimensional deviation.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an outer frame, a horizontal adjustment frame arranged in the outer frame, a longitudinal adjustment frame arranged at the inner end of the horizontal adjustment frame, a rotary adjustment frame arranged at the center of the longitudinal adjustment frame, and double-sided hooks symmetrically arranged at the lower part of the rotary adjustment frame.

[0008] Further, the horizontal adjustment frame is nested and installed inside the outer frame, and the double sides adopt a guide rail and guide wheel structure. The horizontal driving assembly moves the horizontal adjustment frame horizontally inside the outer frame through a push-pull action.

[0009] Further, the longitudinal adjustment frame is nested and installed inside the horizontal frame, and the double sides adopt a guide rail and guide wheel structure. The longitudinal driving assembly moves the longitudinal adjustment frame vertically inside the horizontal frame through a push-pull action.

[0010] Further, the rotary adjustment frame is installed at the center of the longitudinal frame, the middle part of the rotary adjustment frame is a center bearing structure, and the rotary driving assembly rotates the rotary adjustment frame around the lifting center bearing in the longitudinal frame through a gear and tooth ring action.

[0011] Further, the double-sided hooks are symmetrically installed at the lower part of the rotary adjustment frame and adopt a guide rail and hooking guide wheel load-bearing structure. The hook opening and closing driving assembly moves the double-sided hooks horizontally in opposite directions below the rotary adjustment frame through a double-sided synchronous push-pull action.

[0012] Further, the hanging mechanism is a stable frame structure as a whole, and vertical guide wheels are additionally arranged at the side parts of the outer frame. Matching vertical fixed guide rails are additionally arranged in the lifting space of the hoisting equipment, and the side guide wheels of the outer frame are clamped in the fixed guide rails.

[0013] Further, the hanging mechanism is hung at the lower end of the hoisting equipment, the hoisting equipment hangs the outer frame, and the double-sided hooks below the hanging mechanism hang the platform ladle.

[0014] Further, the horizontal driving assembly, the longitudinal driving assembly and the hook opening and closing driving assembly realize linear adjustment actions, which include but are not limited to the driving devices of lead screws, worms, gear racks, electro-hydraulic push rods, oil cylinders and air cylinders.

[0015] The rotation driving assembly achieving the rotation adjustment action includes, but is not limited to, a driving device of gear ring rotation movement.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] (1) in the process of transferring and hoisting the platform, when the platform is taken, the mechanism can automatically adjust the horizontal position and the skew angle of the lower hook in the horizontal direction and the vertical direction, so as to adapt to the platform with the original azimuth angle deviation.
