The invention provides a simple structure, safe and reliable, high efficiency and good quality aluminum electrolysis multifunctional crane end beam combination hoisting special fixture. The invention includes a positioning base, a connecting device, a hoisting shoulder pole and at least two locking clips, and is characterized in that: the positioning base is provided with a positioning track corresponding to the walking wheel of the end beam; Both sides are provided with hoisting shafts, and a hoisting hole is provided above the shoulder pole body corresponding to the hoisting shaft; the locking clips include two symmetrical card bodies, and a card frame that matches the shoulder pole body is arranged between the two card bodies. The lower end is provided with a hook corresponding to the upper end of the end beam, and the upper ends of the two card bodies are connected by a connecting piece; the connecting device includes a connecting beam, and the two ends of the connecting beam are provided with connectors capable of connecting with the ends of the end beam.

Description

technical field [0001] The invention belongs to the technical field of hoisting fixtures, in particular, the invention relates to a special tooling fixture for hoisting combined aluminum electrolytic multifunctional crane end beams. Background technique [0002] The aluminum electrolysis multifunctional crane can complete the shell breaking, pole changing, covering material replenishment, slag cleaning, aluminum tapping, lifting of the anode busbar, lifting the upper and lower structures of the electrolytic cell and other basic operations of the prebaked anode aluminum electrolytic cell. It is mainly composed of carts, tool trolleys, and aluminum tapping trolleys. The cart is the main frame part of the aluminum electrolysis multifunctional crane, mainly composed of: main beam (main beam Ⅰ, main beam Ⅱ, main beam Ⅲ), It is composed of end beams (two left end beams and two right end beams), wheels and other components. Before the whole machine leaves the factory, it must carry...

AI Technical Summary

Problems solved by technology

During the hoisting process, since the length of a single end beam is 6-7m, the weight is 2-3t, and the end beam is suspended in the air for 5-6m, it is difficult to accurately determine the center position of each end beam with a single rope binding method, which needs to be repeated. Find the balance position to determine the center point, and the sequence of lifting can only be carried out after the lifting is balanced. There are many potential safety hazards

[0004] 2. The end beam structure is composed of various plate frame structures, and the edges are mostly angular structures. When using: crane + wire rope + binding method for hoisting, the steel wire rope is in contact with the edge of the end beam. Due to the angular There is a shear force on the steel wire rope, which seriously affects the service life of the steel wire rope; at the same time, due to the weight of the end beam, it is easy to scratch the surface of the finished end beam at the contact point between the steel wire rope and the end beam, which affects the appearance quality of the product

[0006] 4. Due to the high-altitude operation, there are great potential safety hazards. At the same time, due to the constraints of assembly local conditions, it is very difficult to adjust manually at high altitudes. Repeated adjustments and assembly time are long and the efficiency is very low.
