Reset device for metal pipe surface damage recession

Abstract

The invention discloses a reset device for metal pipe surface damage recession, and relates to the technical field of metal pipe wall maintenance. The device comprises a base, wherein an end plate anda main supporting plate are arranged at the top end of the base, and an auxiliary supporting plate is in running fit with the end of the main supporting plate; telescopic rods are rotationally arranged on the main supporting plate and the auxiliary supporting plate, and pipe fitting fixing bases are fixed to the top ends of the telescopic rods; a cross rod is fixed to the top of the end plate andsleeved with a coupler, the two ends of the coupler are rotationally connected with a driven base and a reset extrusion head correspondingly, and a spiral notch is formed in the circumferential sideface of the reset extrusion head; and a sliding plate is slidably matched with the top end face of the base, a side plate is fixed to the upper surface of the sliding plate, and the top end of the side plate is in running fit with the driven base. According to the device, a metal pipe is fixed through cooperation between the main supporting plate and the auxiliary supporting plate, the sliding plate drives the reset extrusion head to slide, and the coupler drives the reset extrusion head to rotate, so that impact and extrusion on the wall of the metal pipe are conducted, recession reset of thewall of the metal pipe is achieved, and the quality of the metal pipe is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metal pipe wall maintenance, in particular to a reset device for damage and depression on the surface of metal pipes. Background technique [0002] Metal pipes are widely used in the field of mechanical engineering, and accidental dents cannot be avoided during use. In the prior art, dents in the metal pipes often affect the engineering quality of the metal pipes. In the field of construction and engineering, in order to facilitate construction and operation, people often use metal pipes to build temporary operating platforms. , some metal pipes will be dented due to the irresistible impact force; resulting in the metal pipes not meeting the requirements in terms of strength, and there will be bending phenomenon during use after construction. At this time, it is necessary to replace the original construction If no measures are taken to remove the metal pipe, it will inevitably bring hidden dangers to the...

[0002] Metal pipes are widely used in the field of mechanical engineering, and accidental depressions cannot be avoided during use. In the existing technology, metal pipes with depressions often affect the engineering quality of metal pipes

In the field of construction and engineering, in order to facilitate construction and operation, people often use metal pipes to build temporary operating platforms. , some metal pipes will be dented due to the irresistible impact force; resulting in the metal pipes not meeting the requirements in terms of strength, and there will be bending phenomenon during use after construction. At this time, it is necessary to replace the original construction If the metal pipe is removed, if no measures are taken, it will inevitably bring hidden dangers to the safety of construction personnel, and will also affect the quality of construction.

[0003] The traditional repair of the metal pipe wall depression is repaired by manpower. First, the metal pipe is placed on a metal rod, and the depression is forced to reset by artificially using a hammer body. This method is relatively primitive. It is time-consuming and labor-intensive, and the curvature of the metal pipe wall cannot be guaranteed. If the metal pipe repaired by this repair method is applied to the project, it will inevitably affect the quality of the project; moreover, the traditional method of repairing the metal pipe wall depression is not suitable for curved metal pipes
