A transmission bracket for a small-diameter steel pipe inner wall shot blasting cleaning machine

Abstract

The invention relates to a conveying bracket of a small-diameter steel pipe inner wall shot blasting machine. The conveying bracket comprises multiple groups of bearing monomers, wherein each group of bearing monomers comprises two outer bending plates in bilateral symmetry; the two outer bending plates are connected through multiple spaced reinforcing plates; adjacent two groups of bearing monomers are connected through two inner bending plates in bilateral symmetry; the outer end of the bearing monomer at the leftmost end is fixedly connected with a first connecting piece; the outer end of the bearing monomer at the rightmost end is fixedly connected with a second connecting piece; a third connecting piece is arranged on the bearing monomer at the leftmost end; multiple upper support roller racks in bilateral symmetry are mounted on the two sides of the upper part of each group of bearing monomers; multiple lower support roller racks in bilateral symmetry are mounted on the two sides of the lower part of each group of bearing monomers; and support rollers are arranged on the upper support roller racks and lower support roller racks. The conveying bracket provided by the invention is reasonable in structure design and convenient to use, improves the rigidity and deflection and meets the requirement for inner wall shot blasting of a small-diameter steel pipe.

Description

technical field [0001] The invention relates to a transmission bracket of a shot blasting cleaning machine for the inner wall of a small-diameter steel pipe. Background technique [0002] The steel pipe inner wall shot blasting cleaning machine is suitable for shot blasting treatment of the inner surface of steel pipes and steel pipe products, and removes sundries such as oxide layer and welding slag to make it appear metallic luster, which is convenient for painting and coating of workpieces. When in use, the transmission bracket of the steel pipe inner wall shot blasting machine should be extended into the steel pipe to perform shot blasting on its inner wall. Due to the small diameter of the steel pipe, the length of the steel pipe is particularly long, so the structural size of the transmission bracket is small, and the size of the rod is long, which will cause the stiffness of the transmission bracket to be small and the deflection large, which affects the shot blasting...
