Grinding device for nodular cast iron jacking pipe and using method thereof

Abstract

The invention discloses a grinding device for a nodular cast iron jacking pipe and a using method thereof. The grinding device comprises a conveying device and a machining platform, wherein the conveying device is arranged on one side of the machining platform, a primary grinding device, a material transferring device, a fine grinding device and a discharging device are arranged on the machining platform, and the conveying device is used for conveying the nodular cast iron jacking pipe to the machining platform for machining. According to the grinding device, the grinding process is continuously carried out, the grinding process does not need to be suspended, the clamping and fixing position of a fixing device on the nodular cast iron jacking pipe is changed, so that the production efficiency is obviously improved; and the nodular cast iron jacking pipe is finely ground through a dustproof grinding ring, after part of the nodular cast iron jacking pipe enters the dustproof grinding ring, the nodular cast iron jacking pipe is ground through a polishing belt, meanwhile, fine dust generated by grinding can be gathered in a hard outer ring, so that the effect that the dust generated bygrinding the surface of the nodular cast iron jacking pipe is greatly discharged from the two ends of the nodular cast iron jacking pipe to pollute the working environment is prevented.

Description

technical field [0001] The invention belongs to the technical field of cast iron processing, and in particular relates to a grinding device for ductile iron pipe jacking and a use method thereof. Background technique [0002] With the rapid progress of urbanization construction, a large number of underground pipelines are laid. Among them, ductile iron pipe jacking is a kind of pipeline mainly used for tap water transportation. It is prepared by welding jacking flanges on the sockets of ordinary ductile iron pipes, and then outsourcing concrete. It is mainly used for pipe jacking construction. [0003] After the ductile iron pipe jacking is fixed and shaped, the surface is rough, which is not convenient for the putty and painting operations in the subsequent process. Therefore, it is necessary to polish the surface of the cast iron pipe jacking to make the surface smooth. In the technology, when the surface of the cast iron pipe jacking is polished, its position needs to be...

Problems solved by technology

[0003] After the ductile iron pipe jacking is fixed and formed, the surface is rough, which is not convenient for the putty and painting operations in the subsequent process. Therefore, the surface of the cast iron pipe jacking needs to be polished to make the surface smooth. In the technology, when the surface of the cast iron pipe jacking is polished, its position needs to be fixed, but when the corresponding position on the surface of the cast iron pipe jacking is polished, the fixed position needs to be replaced to prevent the fixed clamping position from being polished. On the other hand, since the surface of the ductile iron pipe jacking is a concrete layer, a large amount of dust pollution will be generated during grinding, especially the light dust with small particles, which can easily float with the air and pollute the production space. To solve the above problems, the present invention provides the following technical solutions
