Description
Technical Field
The utility model relates to a municipal works equipment technical field especially relates to nodular cast-iron pipe splicing apparatus.
Background
The spherical milling cast iron pipes are often required to be spliced in municipal engineering, and the technical means adopted at present is to push one section of the spherical milling cast iron pipe to the other section of the spherical milling cast iron pipe through a bulldozer for splicing, but the following defects exist: large equipment, that is, a bulldozer, is required. The bulldozer has the dislocation phenomenon of non-butt joint in the pushing process, a large amount of labor is consumed, the cost of the whole process is high, and the working efficiency is low. One end of each nodular cast iron pipe is relatively large, the other end of each nodular cast iron pipe is relatively small, and a port with a larger point and a port with a smaller point are spliced relatively between two adjacent nodular cast iron pipes. And the ductile iron pipe has larger volume and heavy weight, which can not be pushed by hands.
