Abstract
The invention discloses a deformation-preventing device for an evanescent mode ductile iron pipe fitting bell mouth. The evanescent mode ductile iron pipe fitting bell mouth is in a cylindrical shape. The deformation-preventing device for the evanescent mode ductile iron pipe fitting bell mouth comprises a rotating shaft rod (3), sliding blocks (4) and multiple equally-divided sand rings (1), wherein the multiple equally-divided sand rings (1) are spliced to form a sand ring cylinder. The outer surface of the sand ring cylinder is tightly attached to the inner surface of the evanescent mode ductile iron pipe fitting bell mouth (2), and every two adjacent connected equally-divided sand rings (1) are clamped to each other through the corresponding sliding block (4). Opening grooves matched with the sliding blocks (4) are formed in the two sides of the equally-divided sand rings (1). The rotating shaft rod (3) is arranged in the equally-divided rings (1) in a tapping manner. First clamping teeth are arranged on the sliding blocks (4), and second clamping teeth engaged with the first clamping teeth are arranged on the rotating shaft rod (3) so that the sliding blocks (4) can be driven to slide in the length direction of the opening grooves. According to the deformation-preventing device for the evanescent mode ductile iron pipe fitting bell mouth, the defects that in the prior art, sand rings cannot be well fixed to the end face of a bell mouth, and the size can only be fixed are overcome, and the evanescent mode ductile iron pipe fitting bell mouth can be prevented from deforming.
