The invention relates to the field of steel pipe reinforcement, in particular to a fatigue reinforcement device for steel pipe straightening. The invention provides the fatigue reinforcing device for steel pipe straightening. The fatigue reinforcing device aims to solve the problem that the overall bending resistance of the steel pipe is reduced due to fatigue of the material after the steel pipe is straightened. The fatigue reinforcing device for steel pipe straightening comprises a workbench, a working box is fixedly arranged on the end face of the side, away from the ground, of the workbench, a traction cavity is formed in the working box, and a traction device for conducting traction on a steel pipe through rolling wheels is arranged in the traction cavity. A marking cavity is formed between the inner wall of the side, close to the steel pipe entering side, of the traction cavity and the end face of the corresponding side of the workbench in a penetrating mode, and a marking device for conducting fluorescent marking on the bent position of the steel pipe is arranged in the marking cavity.
Description
technical field [0001] The invention relates to the field of steel pipe reinforcement, in particular to a fatigue reinforcement device for straightening steel pipes. Background technique [0002] The steel pipe straightening machine is a kind of maintenance machine for steel pipe scaffold steel pipes of construction fasteners. It is mainly used for straightening and repairing scaffold steel pipes and other pipes that are bent and deformed during construction. [0003] After the steel pipe is straightened, its strength is greatly reduced. The main reason is that the material of the steel pipe is fatigued after many times of bending, resulting in a decrease in the overall bending resistance of the steel pipe. In the subsequent use of the steel pipe, its working performance cannot be obtained. Guaranteed, there are safety hazards such as fracture and bending during work. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the presen...
