Special tool jig for combining and hoisting end beams of multifunctional aluminum electrolysis crane

Abstract

The invention relates to a special tool jig for combining and hoisting end beams of a multifunctional aluminum electrolysis crane. The invention provides the special tool jig for combining and hoisting the end beams of the multifunctional aluminum electrolysis crane, which is simple structure, safe and reliable, high in efficiency and good in quality. The special tool jig comprises a positioning base, a connection device, a hoisting carrying pole and at least two locking clips. The special tool jig is characterized in that the positioning base is provided with a positioning rail corresponding to walking wheels of the end beams; the hoisting carrying pole comprises a carrying pole body; hoisting shafts are arranged on the two sides in the carrying pole body; hoisting holes opposite to the hoisting shafts are formed in the carrying pole body; each locking clip comprises two symmetrical clip bodies; a clamping frame matched with the carrying pole body is arranged between the two clip bodies; a clamping hook is arranged at the lower end of each clip body in a manner of being opposite to the upper end of each end beam; the two clip bodies are connected by a connection piece; the connection device comprises a connection beam; connectors connected with the end parts of the end beams are arranged at the two ends of the connection beam.

Description

Technical field [0001] The invention belongs to the technical field of hoisting tooling and fixtures. Specifically, the invention relates to a special tooling and fixture for hoisting an aluminum electrolytic multifunctional crane end beam combination. Background technique [0002] The aluminum electrolysis multifunctional crane can complete the shelling, pole change, supplementary covering material, slag removal, aluminum tapping, lifting the anode bus, lifting the upper and lower structures of the electrolysis cell and other basic operations. It is mainly composed of carts, tool carts, and aluminum tapping carts. The cart is the main frame part of the aluminum electrolysis multifunctional crane, which is mainly composed of main beams (main beam I, main beam II, and main beam III), The end beams (two left end beams and two right end beams), wheels and other components are composed. Before leaving the factory, the whole machine must undergo a simulation test run of the main frame...

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.
