Abstract

The invention provides a welding heating device for a circular seam in the inner wall of a cylinder. The device includes an electric heating band and an elastic steel strip, the electric heating bandis spread on the inner wall of the cylinder along the circular seam, the elastic steel band is curled to form an annular shape and stacked on the electric heating band, and elastic force of the elastic steel strip makes the electric heating band tightly adhered to the inner wall of the cylinder. When the device is used, firstly the electric heating band is spread on the inner wall of the cylinderalong the circular seam, the elastic steel strip is curled to form the annular shape and is sent to the circular seam in the cylinder and is stacked on the electric heating band, the elastic steel strip in the curled state naturally produces a kind of elastic force returning to a straight state, the elastic force can make the electric heating band tightly adhered to the inner wall of the cylinder,so that the fixing problem of the electric heating band is solved very simply and ingeniously, and continuous heating of the cylinder circular seam is realized.

Description

technical field

[0001] The invention relates to a heating device for circumferential seam welding on the inner wall of a cylinder. Background technique

[0002] In the prior art, when welding the outer circumferential seam of a large cylinder such as a wind power tower, the welding machine is usually aligned with the position of the circumferential seam of the cylinder and then fixed, and then the rotating trolley is used to roll the cylinder, so that the external Circumferential seams are uniformly welded. In order to ensure the welding quality, it is also necessary to carry out comprehensive and continuous heating of the welding seam, and the cylinder in a rolling state is not conducive to comprehensive and continuous heating. SUMMARY OF THE INVENTION

[0003] The technical problem to be solved by the present invention is to provide a circumferential seam welding heating device for the inner wall of the cylinder, which can conveniently and continuously heat the cylinder...
