Description

Tank lifting lug weldment

Technical Field

The utility model belongs to the technical field of welding, and particularly relates to a tank lifting lug weldment.

Background

The welding stress is stress generated by welding the welding members. Internal stress generated in the weldment during welding and shape and size changes of the weldment caused by welding thermal process. Welding stresses and deformations can under certain conditions affect the function and appearance of the weldment.

At present, as shown in fig. 5, the method for solving the stress is to pre-drill a plurality of through holes in the base in advance to solve the problem of stress concentration, so that the operation is simple, but the method has the defect that rainwater can enter from the through holes, thereby corroding weld scars and causing corrosion and welding removal of the weld.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a welding structure for releasing stress concentration, which is characterized in that a stress release groove is added at a position where stress concentration is easy to generate so as to release or release the stress concentration at the welding stress concentration position, thereby avoiding cracking caused by stress concentration or stress superposition and preventing rainwater corrosion.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a jar body lug weldment, includes the shell of jar body, the side or the top of shell are equipped with a plurality of weldments that are used for carrying, lift by crane, the weldment includes the base and welds the lifting lug at the base lateral surface, the welding face center department of base is equipped with the stress groove that is used for releasing stress, the cross-section in stress groove is the U-shaped, the opening in U-shaped groove is towards ground.

In the above technical scheme, the stress groove is in a strip structure, or in an annular structure or a semicircular structure.

The utility model has the beneficial effects that: the utility model effectively releases stress by improving the stress groove of the weldment, avoids the cracking of the welding part due to stress superposition, simultaneously prevents the welding scar from being corroded by rainwater, and reduces the probability of welding scar and welding-free. The utility model has the characteristics of simple structure, convenient processing and easy assembly, and has strong practicability.

Detailed Description

As shown in fig. 1-4, a tank lifting lug weldment comprises a tank shell 1, wherein a plurality of weldments for carrying and lifting are arranged on the side surface or the top of the shell 1, each weldment comprises a base 2 and a lifting lug 3 welded on the outer side surface of the base, a stress groove 4 for releasing stress is arranged in the center of a welding surface of the base 2, the section of each stress groove is of a U-shaped structure, and the opening of each U-shaped groove or M-shaped groove faces the ground.

In the above technical solution, the stress groove 4 is a bar structure, or is a ring structure or a semicircular structure.

In this embodiment, firstly, one surface of the iron square base 2 is milled to form a U-shaped or M-shaped stress groove 4 with a depth of 1-10mm and a width of 1-8mm, then the other surface of the base 2 is welded with the lifting lug 3, after the operation of the combined weldment is completed, three combined weldments are welded on the side surface or the top of the shell of the tank body, the notch of the stress groove 4 faces the ground, and the cross section of the stress groove can be in a circular structure.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be appreciated by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the utility model, and that simple modifications and substitutions by those skilled in the art are within the scope of the utility model without departing from the spirit and scope of the utility model.
