Description

Technical Field

[0001] The invention relates to the field of welding positioning platforms, in particular to an automatic welding positioning platform for a steel cage. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as the wild, underwater and in space. No matter where it is, welding may bring danger to the operator, so appropriate protective measures must be taken when welding. The possible harm caused by welding to the human body includes burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] The main role of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension. During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to requirements. The method is to use machine punching and water drilling, and the hole depth meets the design requirements. Then lower the steel cage into the pile hole, and insert the guide tube to pour concrete. In addition, when the concrete structure is a columnar or strip-shaped component, the center part does not need to be reinforced. Only steel bars are arranged under the surface of the concrete component that contacts the air. If this component is independent, the steel bars set around this component are pre-made. This is a steel cage. We usually call pre-made steel structures such as bored piles, excavated piles, and columns steel cages.

[0004] Based on the existing technology, when assembling the steel cage, it is necessary to use a positioning table to support the steel cage. However, the welding positioning table in the existing technology needs to rotate the steel cage when welding the steel cage. Since the steel cage is long, when the steel cage is flipped as a whole, the steel cage is easily twisted under the action of the gravity of the steel cage, and the welding quality of the steel cage is poor. Summary of the Invention

[0005] The present invention provides an automatic welding positioning table for a steel cage, which solves the problem in the prior art that the welding positioning table needs to rotate the steel cage when welding the steel cage. Due to the long length of the steel cage, when the steel cage is flipped as a whole, the steel cage is easily twisted under the action of the gravity of the steel cage, resulting in poor welding quality of the steel cage.
