Concrete mixing tank front cone and middle cylinder assembly welding device

Abstract

The invention discloses a concrete mixing tank front cone and middle cylinder assembly welding device. The device comprises a platform, a guide column, a circle supporting mechanism and a clamp, during assembly, a first shell ring is placed on an assembling mechanism firstly, the shell ring and the assembly mechanism are restrained to be coaxial through the circle supporting mechanism, then a second shell ring is placed on the first shell ring, the second shell ring is restrained to be coaxial with the assembling mechanism, after the two shell rings are coaxial, the top of the second shell ring is clamped and pressed downwards through a liftable guide shaft, and spot welding is started at the joint of the two shell rings after it is guaranteed that the two shell rings are attached in place. According to the concrete mixing tank front cone and middle cylinder assembly welding device, when two shell rings are subjected to assembly spot welding, the two shell rings are restrained to be coaxial and can adapt to assembly of multiple shell rings with different diameters and different heights, and a large number of special tools do not need to be replaced.

Description

technical field [0001] The invention relates to a butt welding device, in particular to a butt welding device suitable for the front cone and the middle barrel of a concrete mixing tank. Background technique [0002] During the production of the concrete mixing tank body, the butt welding process of the barrel joint and the barrel joint group needs to ensure the coaxiality and roundness of the final forming of the tank body. In actual production, one-to-one special tooling fixtures are used to round the bottom barrel section first, and then another barrel section is hoisted above the bottom barrel section for stacking, and finally at the joint between the barrel sections Do external spot welds. [0003] Most of the existing tooling is manual, huge in size and heavy in weight. The installation labor intensity of workers is high, the installation time is long, and the efficiency is low. Moreover, a large number of hoisting operations need to be carried out by driving during i...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing tooling is manual, with huge volume and heavy weight. The installation labor intensity of workers is high, the installation time is long, and the efficiency is low. Moreover, a large number of hoisting operations need to be carried out by driving during installation, and the risk factor is very high.

At the same time, most of the existing tooling is dedicated and cannot be changed in diameter. Therefore, it is necessary to prepare multiple sets of tooling in daily production to meet the demand. The increase in the number of tooling requires a large area for storage.

During butt welding, the tooling only stacks and positions the butt surface, and when the plane butt joint of the butt surface is poor, the coaxiality of the tank body cannot be guaranteed
