Abstract

The invention relates to the field of ship engineering welding, in particular to a jig frame used for cylindrical pile leg barrel submerged-arc welding. The jig frame comprises base universal wheels, a base, a height-adjustable support, an operation platform, height adjustment holes, locking sleeves, a crawling ladder and a platform guardrail. The base is arranged on the base universal wheels. The base is fixedly connected with the height-adjustable support. The height-adjustable support is fixedly connected with the operation platform through the height adjustment holes and the locking sleeves. The height-adjustable support and the operation platform are welded and fixed. By means of the jig frame, hoisting of welding devices can be effectively reduced while the welding quality is ensured, and collision of the welding devices is avoided; a submerged-arc welding machine is placed on the operation platform with the guardrail, and safety of welding personnel and the welding devices is ensured.

Description

technical field [0001] The invention relates to the field of shipbuilding engineering welding, in particular to a tire frame used for submerged arc welding of cylindrical leg cylinders. Background technique [0002] The manufacture of cylindrical pile legs is composed of a cylinder and a rack plate. The butt ring seam of the cylinder needs to be welded on the roller frame. Due to the large diameter of the cylinder, the welding position of the cylinder is relatively high during the butt joint. The support device is usually used to place the submerged arc welding machine at a designated position for welding work, but the support device cannot guarantee the stable and stable welding work at present, and the welding quality of the butt joint of the cylinder is also unstable. Contents of the invention [0003] The present invention provides a tire frame for submerged arc welding of cylindrical leg cylinders to solve the above-mentioned problems in the background technology. The...
