Grinding device for ductile iron pipe jacking

Abstract

The invention discloses a polishing device for a nodular cast iron ejection pipe. The polishing device comprises a polishing unit and a dedusting unit. The polishing unit comprises a polishing wheel and a movable rack. The movable rack can move freely, and the grinding wheel is fixed to the movable rack. The dedusting unit is also fixedly connected to the movable rack. The polishing wheel and the dedusting unit both can move along with the movement of the movable rack. According to the polishing device, the polishing position of the polishing wheel can be adjusted according to the size dimension of a polished piece, and meanwhile the position of a dust hood is correspondingly changed so as to be matched with the polishing unit for synchronous dust removal, and thus the good dust removal effect can be achieved.

Description

technical field [0001] The invention relates to the field of cast iron processing, in particular to a grinding device for ductile iron pipe jacking. Background technique [0002] The surface of the ductile iron pipe jacking is affected by factors such as secondary pouring and the use of molds. After the concrete is poured and the formwork is removed, horizontal and vertical bosses or burrs will appear on the surface between the molds and the joints, which will affect the putty on the surface. , painting and other follow-up processes; therefore, the surface of the ductile iron needs to be polished until the surface is smooth and flat. [0003] At present, the dust pollution generated when grinding the ductile iron pipe jacking is very large, and the traditional grinding method is that the grinding unit and the dust removal mechanism are independent and fixed; The problem of dust pollution generated during grinding of cast iron jacking pipes. And the dust that long-term grin...

Problems solved by technology

[0003] At present, the dust pollution generated when grinding the ductile iron pipe jacking is very large, and the traditional grinding method is that the grinding unit and the dust removal mechanism are independent and fixed; Dust Pollution Produced During Grinding of Cast Iron Pipe Jacking

However, the dust produced by long-term grinding treatment has great damage to the physical and mental health of operators; therefore, it is necessary to provide a grinding device for ductile iron pipe jacking with good dust removal effect
