Problems solved by technology

[0003] Some sewers can be seen in the existing highways and various communities. According to the type, the sewers can be divided into rectangular sewers and circular sewers. The circular sewers are used in a wide range, and the sewers need to be cleaned manually every time. Silt and sundries, otherwise the sewer may be blocked, which seriously affects the dredging functi

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of grabbing machinery, in particular to a radial locking device for a sewer decontamination grab bucket. Background technique [0002] The grab is a kind of spreader that mainly depends on the opening and closing of two left and right combined buckets or multiple jaw plates to grab and discharge bulk materials. The grab can be divided into two types: hydraulic grab and mechanical grab according to the driving mode. Large category, the hydraulic grab itself is equipped with an opening and closing structure, generally driven by a hydraulic cylinder, and the hydraulic grab is widely used in hydraulic special equipment, such as hydraulic excavators, hydraulic lifting towers, etc.; and the mechanical grab itself There is no opening and closing structure, and it is usually driven by the external force of a rope or a connecting rod. According to the operating characteristics, it can be divided into a double-rope gr...
