Description

Technical Field

[0001] The invention belongs to the technical field of supporting devices, and in particular relates to a stainless steel pipe weld supporting device. Background Art

[0002] Stainless steel pipe is a hollow long strip of steel. The wall of stainless steel pipe is thin. When processing the weld of the pipe, it is easy to have local cracking of the weld due to various reasons. At this time, it is necessary to repair the weld. The cross section of traditional stainless steel pipe is usually circular. In some specific occasions, stainless steel pipe with a rectangular cross section is also used. When the staff wants to weld two unconnected rectangular stainless steel pipes, they need to use a stainless steel pipe support device; The traditional stainless steel pipe support device is usually composed of a clamping structure and a supporting structure. The supporting structure can support the stainless steel pipe that is not connected at both ends, and the clamping structure can clamp the stainless steel pipe on the supporting structure, and at the same time, the two sections of stainless steel pipe that are not connected can be stably spliced ​​together. When this clamping structure is used in conjunction with the supporting structure, it can indeed achieve a good splicing effect on the two sections of stainless steel pipe that are not connected. However, this supporting structure is usually not provided with a good angle adjustment structure. When the staff wants to splice and weld two sections of stainless steel pipe that are not connected, they usually place other objects on the bottom of the stainless steel pipe, or fix the stainless steel pipe in a suspended manner, which easily leads to errors in the welding angle of the stainless steel pipe. At the same time, the existing stainless steel pipe support device is not yet provided with a cleaning structure, and other debris is easily adhered to the end of the stainless steel pipe.

The faster the speed, it can be understood that each group of spherical grooves 38 is distributed in a circular array, and the number of each group of spherical grooves 38 is the same. Imagine the distribution of each group of spherical grooves 38 as a complete circle, the circumference of the inner circle is smaller than the circumference of the outer circle. When the number of spherical grooves 38 is the same, the smaller the circumference of the circle, the smaller the spacing between the spherical grooves 38.
