Description

Technical Field

[0001] The invention belongs to the field of construction machinery and equipment, and particularly relates to a mobile pile head steel bar automatic straightening device. Background Art

[0002] In recent years, construction projects have placed higher demands on construction equipment and machinery, and stricter energy conservation and environmental protection requirements have increased costs for construction companies. Construction companies are also pursuing refined management, demanding efficiency and effectiveness from management, reducing the workload of construction workers, improving operational efficiency, and promoting high-quality development. Furthermore, they are also demanding that environmental pollution be reduced and protected during construction. Most importantly, this requires improving worker efficiency and safety. Currently, concrete is removed from the pile head using jackhammers, electric picks, or hammers. This concrete breakage causes deformation and bending of the main reinforcement around the pile head, requiring alignment before further construction. This alignment relies on several workers using rebar wrenches to pry and adjust the reinforcement. This makes access difficult for workers inside the pile cage, and the small, inconvenient location directly impacts construction quality and progress, increasing costs. Currently, there is no mobile, simple, fast, and efficient automatic straightening device for pile head reinforcement. Summary of the Invention
