Abstract

The invention discloses a device for removing a cement lining of a spherical-graphite cast-iron pipe and relates to the technical field of casting-pipe cleaning equipment. The device comprises a traveling trolley, wherein a supporting rod is fixed on the traveling trolley; a pneumatic device is fixed at the left end of the supporting rod and is provided with an alloy radial hammering cylinder head; the left side of the traveling trolley is provided with a power supporting wheel group of the spherical-graphite cast-iron pipe; the supporting rod is parallel to the axis of the spherical-graphite cast-iron pipe. The device disclosed by the invention has the advantages that the cement lining can be removed without need of damaging the spherical-graphite cast-iron pipe, so that the production cost is greatly reduced.

Description

A kind of removing ductile iron pipe cement lining device
Technical field
The present invention relates to cast tube cleaning equipment technical field, relate in particular to a kind of for ductile iron pipe removing cement lining device.
Background technology
The molten casting iron of use more than No. 18, after adding nodulizer, through the fluid origin tubing of centrifugal ductile pig machine high speed centrifugation, is referred to as " ductile iron pipe ", referred to as bulb, ductile iron pipe and ductile iron pipe etc.The cement mortar liner of ductile iron pipe mainly contains the effect of two aspects: being the decay resistance that can improve ductile iron pipe on the one hand, is the effect that can play protection water quality on the other hand.Therefore, the cement mortar liner of ductile iron pipe not only its thickness and surperficial quality will meet relevant technical standard, and must not produce any injurious effects to water quality.The current factory of centrifugal cast iron pipe at home, stream in ductile iron pipe inner wall liner cement occurs, pitting, the mass defects such as fritter, ordinary circumstance is crushed ductile iron pipe exactly, the mud that anhydrates, and then melt down casting again.So just because of the cement defect, ductile iron pipe is also destroyed simultaneously, wasted raw material, caused cost to increase greatly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of removing ductile iron pipe cement lining device, uses described device just cement lining can be removed without destroying ductile iron pipe, greatly reduces production cost.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of removing ductile iron pipe cement lining device, it is characterized in that comprising walking dolly, be fixed with support bar on walking dolly, the left end of support bar is fixed with aerophor, and aerophor is provided with alloy and radially knocks cylinder head; The left side of walking dolly is provided with ductile iron pipe power support roller group, and support bar is parallel with the axis of ductile iron pipe.
Preferably, described support bar is metal tube, and the right-hand member of support bar is provided with air inlet, and compressed air enters metal tube through air inlet and provides power for alloy radially knocks cylinder head.
Preferably, the left side of aerophor is provided with support wheel.
Preferably, be provided with support roller station below described support bar, described support roller station fixes on the ground.
The beneficial effect that adopts technique scheme to produce is: the present invention includes support bar, walking dolly, ductile iron pipe power support roller group and aerophor etc., ductile iron pipe is placed on ductile iron pipe power support roller group, the support roller group drives ductile iron pipe and rotates, aerophor is under the drive of dolly, slowly enter the inside of ductile iron pipe for clearance, compressed air drive alloy radially knocks cylinder head and beats cement lining.Along with the movement of walking dolly and the rotation of ductile iron pipe, beat by forming line, line forms face, in dolly advances slowly, clean out the cement lining that intensity is very high, can not destroy ductile iron pipe, reach the purpose of recycling ductile iron pipe, greatly reduce production cost.In addition, described device simple in structure, easy to use, low cost of manufacture, remove effectively, has and promote preferably and prospect of the application.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
Wherein: 1, walking dolly 2, air inlet 3, support bar 4, aerophor 5, ductile iron pipe 6, ductile iron pipe power support roller group 7, support roller station 8, alloy radially knock cylinder head 9, cement lining 10, support wheel.
The specific embodiment
As shown in Figure 1, a kind of removing ductile iron pipe cement lining device, comprise walking dolly 1, support bar 3, aerophor 4, ductile iron pipe power support roller group 6 and support roller station 7.Be fixed with support bar 3 on walking dolly 1, the left end of support bar 3 is fixed with aerophor 4, and aerophor 4 is provided with alloy and radially knocks cylinder head 8, and it is vertical with the inwall of ductile iron pipe that alloy radially knocks cylinder head.Preferably, described support bar 3 is used metal tube, and the right-hand member of support bar 3 is provided with air inlet 2, and compressed air enters metal tube through air inlet 2, for alloy radially knocks cylinder head 8, provides power.The left side of walking dolly 1 is provided with ductile iron pipe power support roller group 6, and the support roller group is used four, and support bar 3 is parallel with the axis of ductile iron pipe 5, and ductile iron pipe can rotate under the drive of ductile iron pipe power support roller group.The left side of aerophor 4 is provided with support wheel 10, and support wheel can rotate with the rotation of ductile iron pipe, plays a supporting role.Be provided with support roller station 7 below described support bar 3, described support roller station 7 fixes on the ground, and support roller station plays the effect of further supported bar.
Aerophor 4 is positioned at ductile iron pipe 5, ductile iron pipe 5 is along with ductile iron pipe power support roller group 6 is rotated, support wheel 10 and then rotates, compressed air makes aerophor 4 work by the pipeline on support bar 3 or support bar, compressed air drive alloy radially knocks cylinder head and moves up and down, the cement lining 9 of rattle balls graphite cast iron pipe 5 inwalls, walking dolly 1 slowly motion forward simultaneously, support roller station 7 is asking support bar 3 slowly to travel forward, after cement lining 9 is all removed, support roller station 7 raises, and walking dolly 1 drives support bar 3 and exits fast.The size of support wheel 10 can change according to the ductile iron pipe specification; Alloy radially knocks cylinder head 8 and makes for alloy material, has enough hardness, can reuse; Support roller group and walking dolly speed can be used automatic control equipment to realize on regulating.
Along with the movement of walking dolly and the rotation of ductile iron pipe, beat by forming line, line forms face, in dolly advances slowly, clean out the cement lining that intensity is very high, can not destroy ductile iron pipe, reach the purpose of recycling ductile iron pipe, greatly reduce production cost.In addition, described device simple in structure, easy to use, low cost of manufacture, remove effectively, has and promote preferably and prospect of the application.
Applied specific case herein principle of the present invention and embodiment thereof are set forth, the explanation of above embodiment is just with helping understand method of the present invention and core concept thereof.It should be pointed out that for the person of ordinary skill of the art, can also carry out some improvement and modification to the present invention under the premise without departing from the principles of the invention, these improvement and modification also fall in the protection domain of the claims in the present invention.
