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 function of the sewer. There are also a small amount of decontamination grab equipment in the prior art, but because the sewer mouth is small, the existing decontamination grab is difficult in the sewer. operation, resulting in defects such as complex operation, slow cleaning speed and low work efficiency in the existing decontamination grab equipment during the working process

Embodiment Construction
[0017] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict.
[0018] Such as Figure 1 to Figure 7 As shown, a special radial locking device for sewer decontamination grabs includes a top cover 1, a locking box 2, a hydraulic cylinder 3, a flange 4, a fixing block 5 and four locking branches 6. The The top cover 1 includes a cross-shaped cover plate 11, an upper T-shaped mounting column 12 and four No. 1 sector blocks 13. The upper T-shaped mounting column 12 is a hollow cylindrical structure, and the upper end surface of the upper T-shaped mounting column 12 is along the top cover 1. Four upper mounting holes are provided symmetrically on the central axis...

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 grab and lift machinery, in particular to a radial locking device for a sewer decontamination grab. Background technique [0002] Grab is a spreader that mainly relies on the opening and closing of two left and right combined buckets or multiple jaws to grab and unload bulk materials. According to the driving mode, the grab can be divided into hydraulic grab and mechanical grab. Large category, the hydraulic grab itself is equipped with an opening and closing structure, and is generally driven by a hydraulic cylinder. The hydraulic grab is widely used in hydraulic special equipment, such as hydraulic excavators, hydraulic crane towers, etc.; and the mechanical grab itself There is no opening and closing structure, usually driven by rope or connecting rod external force. According to the operating characteristics, it can be divided into double rope grab and single rope grab. The most commonly used is double rop...
