A horizontal rotary device for a conical cylinder

Abstract

The invention discloses a horizontal rotating device for a conical barrel body. The horizontal rotating device comprises support rings and hinged supports installed on the support rings, each support ring is a disc-shaped member, through holes are evenly distributed at the periphery of each support ring, and each group of through holes comprises a plurality of pairs of equidistant through holes distributed radially along the support ring. The support surfaces of lower hinged supports are uniformly in contact with the periphery of the outer circular conical surface of the conical barrel body at the same time, the horizontal rotating device is guaranteed to clamp the conical barrel body coaxially, the connection positions of upper hinged supports and the radial through holes of the support rings are adjusted, and then the distances from the lower hinged supports to the axes of the support rings are changed to adapt to clamping of the conical barrel bodies of different diameters. The horizontal rotating device is novel and simple in structure, and when the rotating device clamps the conical barrel body to roll on an idler wheel, the various operations like automatic welding for the butted joint of the long conical barrel body, multi-directional mounting on a cone body, and welding parts inside and outside the cone body are completed.

Description

technical field [0001] The invention relates to the field of pipeline and pressure vessel manufacture, in particular to a welding manufacture of a cone skirt cylindrical body of a tower vessel. Background technique [0002] The tower container is a vertical container with a large length in the petrochemical container. The cone-shaped skirt cylinder is widely used in tower containers with small inner diameter, high height and large wind load. Through the advantage of increasing the diameter of the large mouth end of the cone, the number of anchor bolts and the bearing area of ​​the foundation plate are increased. The standard The half-cone vertex angle of the cylinder body of the upper conical skirt seat should not exceed 15°. [0003] The cone-shaped skirt cylinder is spliced ​​by multi-section cones according to the length. Since it is difficult to rotate along the axis, the butt weld of the cone-shaped cylinder cannot be welded by an automatic welding machine. The cone-sh...

AI Technical Summary

Problems solved by technology

[0005] At present, the crane is used to turn over the conical cylinder for measurement work, but if the crane is used for a long time, there are many difficulties and disadvantages, such as: 1. It is easy to cause deformation of the clamping position of the cone; 2. There is a bump on the outer wall of the cone The risk of parts; 3. Unable to install the connection accurately; 4. Frequent operation of the crane is required, which is time-consuming and labor-intensive
