Improved more than half circle welding support of diverter

The utility model relates to the technical field of machinery, in particular to an improved more than half circle welding support of a diverter, comprising a left base, a right base, a front side support and a rear side support, wherein the front side edge of the left base is fixed with the left bottom end of the front side support; a ring of the front side support takes a shape of more than half circle; the right bottom end of the front side support is fixed with the front side edge of the right base; the rear side edge of the right base is fixed with the right bottom end of the rear side support; a ring of the rear side support takes a shape of more than half circle; and the left bottom end of the rear side support is fixed with the rear side edge of the left base. Compared with the prior art, the improved large semi-circle welding support has the following advantages: the front and rear side supports respectively adopt a more-than-half-circle-shaped ring structure, so that the utilization range of welding
