Description

A positioning tool for welding crane parts

Technical Field

The utility model relates to the technical field of crane parts production, in particular to a positioning tool for welding crane parts.

Background Art

A crane is a multi-action lifting machine that can lift heavy objects vertically and move them horizontally within a certain range. It is widely used in logistics, construction and other industries. When welding crane accessories, the accessories need to be positioned to ensure the accuracy of the welding installation position. Most of the existing accessory positioning tools are fixed, and the accessories are directly mounted on the positioning blocks of the positioning tools for welding. During welding, the positioning device is likely to interfere with the connection between the accessories and other accessories of the crane.

In the prior art, a Chinese patent document with a publication number of CN214393048U is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: a crane counterweight sleeve welding positioning tool, including a base, four support columns are arranged on the top of the base, a fixed plate is connected between the tops of the four support columns, two drive cylinders are installed on the top of the base, a connecting plate is connected between the ends of the piston rods of the two drive cylinders, a positioning column is arranged on the top of the connecting plate, and the top of the positioning column extends to the top of the fixed plate, and two mounting plates are arranged on both sides of the top of the fixed plate. Two clamping cylinders are arranged on the inner side of each mounting plate, and a clamping block is connected between the ends of the piston rods of the two clamping cylinders. The crane counterweight sleeve welding positioning tool, when positioning, drives the positioning column to move upward to extend above the fixed plate by the driving cylinder, which is convenient for positioning. After positioning is completed, the driving cylinder drives the positioning column to move downward to below the top of the fixed plate to prevent the positioning column from affecting the connection between the counterweight sleeve and other accessories of the crane, which is convenient for welding.

In order to solve the problem that the positioning device is easy to interfere with the connection between the accessory and other accessories of the crane during welding when the accessory is directly mounted on the positioning block of the positioning tool. The prior art uses a driving cylinder in conjunction with a positioning column for positioning. However, the positioning tool cannot rotate after clamping the crane accessory, which results in a limited welding angle range and requires workers to perform surrounding processing, which is complicated to operate.
