Pipeline dredging device

The invention relates to a radial locking device special for a blowdown grab for a sewer, and belongs to the technical field of grabbing and lifting machines. The radial locking device comprises a top cover, a locking box, a first hydraulic cylinder, a flange, a fixed block and four locking branched chains, wherein the top cover comprises a cross-shaped cover plate, an upper T-shaped installation column and four first sector blocks; the locking box comprises a cross-shaped box body, a lower T-shaped installation column and second sector blocks; the lower end of the first hydraulic cylinder is installed on the locking box, and a piston rod of the first hydraulic cylinder is connected with the flange through threads; the fixed block is connected with the flange through bolts; the four locking branched chains are installed on the locking box. Each locking branched chain comprises a hollow slideway, a linear sliding rail, an ejector rod, an adjusting rod, a limiting spring, a sliding chute and a sliding column. The radial locking device can assist in existing blowdown grab equipment in rapidly cleaning the sewer and cleaning away sludge and dirt, and has the advantages of being easy and convenient to operate, high in cleaning speed, high in working efficiency and the like.
