The invention relates to the technical field of pipe fitting hoisting, in particular to special hoisting equipment for nodular cast iron pipes. Aiming at the problems of inconvenient hoisting and low pipe fitting butt joint efficiency in the prior art, the following scheme is proposed that the special hoisting equipment comprises a support, and the support comprises a top plate, a butt joint plate fixedly connected to the bottom of one end of the top plate, a moving plate slidably connected to the bottom of the top plate and a driving assembly installed at the bottom of the top plate and used for driving the moving plate to slide along the bottom face of the top plate. The special hoisting equipment for the nodular cast iron pipes is reasonable and stable in structure and easy to operate, nodular cast iron pipe fittings to be installed can be automatically clamped, automatic butt joint further can be performed on the nodular cast iron pipe fittings, installation of the nodular cast iron pipes is more convenient, and the special hoisting equipment is easy to popularize and use.
Description
technical field [0001] The invention relates to the field of pipe fitting hoisting, in particular to a special hoisting device for ductile iron pipes. Background technique [0002] Ductile iron pipe refers to the pipe made by high-speed centrifugal casting of centrifugal ductile iron machine after casting molten iron above No. 18 with the addition of nodularizer, referred to as ball pipe, ductile iron pipe and ductile cast pipe. Ductile iron has the essence of iron, the performance of steel, excellent anti-corrosion performance, good ductility, and easy installation. It is mainly used for water supply and gas transmission in municipal industrial and mining enterprises. It is an ideal material for tap water pipelines. [0003] Most of the ductile iron pipes in the prior art are socket-type structures. When in use, after the sealing ring is installed inside the socket end, the insertion end of another pipe fitting is inserted into the inside of the socket end, but the nominal ...
