Description

Technical Field

[0001] The present invention relates to the field of welding positioning tables, and particularly to an automatic welding positioning table for steel reinforcement cages. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasonic waves. In addition to being used in factories, welding can also be carried out in various environments, such as in the wild, underwater, and in space. Wherever it is, welding may pose risks to operators. Therefore, appropriate protective measures must be taken during welding. The injuries that welding may cause to the human body include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc.

[0003] The main function of the steel reinforcement cage is the same as that of the longitudinal steel bars in the column, mainly playing a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a role in restraining the pile body concrete so that it can withstand a certain axial tensile force. During the construction of bridges, culverts or high-rise buildings, according to requirements, piling may be required for the foundation. The method is to use machines to punch holes and water mill drill holes, and the hole depth reaches the design requirements. Then, the steel reinforcement cage is lowered into the pile hole, and a conduit is inserted for concrete pouring. In addition, when the concrete structure is a columnar or strip-shaped member, no steel bars are required in the central part, and steel bars are only arranged under the surface of the concrete member in contact with the air. If this member is independent, the steel bars arranged around this member are prefabricated, and this is the steel reinforcement cage. Usually, the prefabricated steel bar structures such as bored cast-in-place piles, dug piles, and columns are called steel reinforcement cages.

[0004] Based on the prior art, when assembling the steel reinforcement cage, a positioning table is needed to support the steel reinforcement cage. However, when the existing welding positioning table welds the steel reinforcement cage, the steel reinforcement cage needs to be rotated. Due to the long length of the steel reinforcement cage, when the whole steel reinforcement cage is flipped, under the action of the gravity of the steel reinforcement cage, the steel reinforcement cage is prone to distortion, and the welding quality of the steel reinforcement cage is poor. Summary of the Invention

[0005] The present invention provides an automatic welding positioning table for steel reinforcement cages, which solves the problem that when the existing welding positioning table welds the steel reinforcement cage, the steel reinforcement cage needs to be rotated.
