Abstract
The invention discloses a ductile iron pipe inner lining holding roller comprising a holding roller support and a roller body which is located on the holding roller support and which rotates freely. The holding roller is characterized by comprising an inner sleeve (3) and an outer sleeve (4) sleeved with the inner sleeve (3), a rubber layer (4-1) is fixed to the outer surface of the outer sleeve (4), and at least one V-shaped radiating groove (5) is formed in the surface of the rubber layer (4-1). Since at least one V-shaped radiating groove is formed in the surface of the rubber layer, the radiating area of the rubber layer is increased, and heat can be radiated through the V-shaped radiating grooves in the process that the rubber layer contacts with a ductile iron pipe rotating in the high speed; meanwhile, the problem of heat expansion deformation of the rubber layer can be solved through the space clearances of the V-shaped radiating grooves; thus, the problem that the rubber layer is damaged owing to the produced friction produced by the ductile iron pipe and the holding roller rotating in the high speed is solved.
Description
Technical field
The present invention relates to a kind of ductile iron pipe internally coated lining support roller.
Background technology
In ductile iron pipe production process, inwall will apply the certain thickness cement mortar coating of one deck.Coating procedure normally limits ductile iron pipe by two support roller groups, a press nips, drives ductile iron pipe High Rotation Speed, utilize centrifugal force that cement mortar is attached on ductile iron pipe inner wall by one of them support roller group as driving wheel.Here the support roller in said support roller group and press nips and the structure of pinch roller are identical.The outer surface of support roller have one deck play buffering and increase the rubber layer of frictional force effect, because the weight of ductile iron pipe is all heavier, and be High Rotation Speed, the frictional force that ductile iron pipe and support roller High Rotation Speed produce is easy to that rubber layer is generated heat and damages; Simultaneously because the rubber layer of support roller is that entirety is fixed in support roller and puts, after rubber layer damages, support roller maintenance is extremely inconvenient, therefore easily causes support roller to be scrapped when changing rubber layer; Again, the bearing rotated owing to making support roller is exposed in workshop condition, and bearing is easy to contaminated, shortens the service life of bearing.
Summary of the invention
The technical problem to be solved in the present invention is: the ductile iron pipe internally coated lining support roller providing a kind of good heat dissipation effect, thus it is damaged because of heating that rubber layer is not easy.
Meanwhile, a kind of easy accessibility is provided, keeps in repair ductile iron pipe internally coated lining support roller that is convenient, long service life.
For solving the problems of the technologies described above, ductile iron pipe internally coated lining support roller of the present invention comprises roller bracket and is positioned at the support roller that roller bracket freely rotates, it is characterized in that: described support roller comprises inner sleeve and is sleeved on the overcoat of lining the outer surface of, the outer surface of described overcoat is fixed with rubber layer, and described rubber layer surface is provided with at least 1 V-arrangement radiating groove.
By arranging the V-arrangement radiating groove of at least 1 on the surface of rubber layer, thus add the area of dissipation of rubber layer, and then make rubber layer in the process contacted with the ductile iron pipe of High Rotation Speed, timely heat can be shed by multiple V-arrangement radiating groove; Meanwhile, the problem of rubber layer expanded by heating distortion can be solved by the spatial joint clearance of V-arrangement radiating groove.Therefore, solving frictional force that ductile iron pipe and support roller High Rotation Speed produce makes rubber layer generate heat the problem damaged.
As a modification of the present invention, described overcoat also includes the outer sleeve between rubber layer and inner sleeve, and described outer sleeve is coordinated by key with between inner sleeve.After this mode utilizing key to coordinate of employing, overcoat can be easy to take out, instead of whole support roller or inner sleeve are pulled down, only need simple replacing and dismounting overcoat in maintenance process, easily and effectively.
As further improvement of the present invention, one end of described inner sleeve is provided with the stepped projection of annular, and the other end is provided with the hold-down ring of the annular that can freely dismantle, and described hold-down ring and male cooperation compress overcoat.Hold-down ring structure is utilized to be more convenient for dismounting and the assembling of overcoat; Be provided with the stepped projection of annular in one end of inner sleeve, overcoat just can fix by the parts not recycling other, and structure is more simple, firm.
Improve as another kind of the present invention, there are two bearings of fixing inner sleeve the centre of described inner sleeve, and described bearing is sealed in the middle confined space of inner sleeve by bearing cap.Utilize bearing cap by space airtight in the middle of inner sleeve for bearing seal, effectively separate with the environment in workshop, avoid the dust in workshop, floating thing etc. and enter the wearing and tearing increasing bearing in bearing, effectively raise the service life of bearing.
Described overcoat is 2-10, and whole overcoat is effectively divided into a few part, advantageously in maintenance by such structure.Change when rubber layer damages time instead of by whole overcoat, can selectively carry out changing or keeping in repair, and other can normally use.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Embodiment one
Fig. 1 shows the first embodiment of ductile iron pipe internally coated lining support roller of the present invention.As shown in Figure 1, whole ductile iron pipe internally coated lining support roller comprises roller bracket 1 and support roller 2 forms, and roller frame 1 fixes support roller 2 by supporting-roller shaft 7 and two bearings 8 be fixed in supporting-roller shaft 7.As shown in Figure 1, be arranged to ladder circular shaft in the middle of supporting-roller shaft 7, square shaft is arranged at two ends and supporting-roller shaft 7 is located by connecting by this square shaft and roller bracket 1.Wherein two bearings 8 are sealed in the confined space in the middle of inner sleeve 3 by the bearing cap 9 at two ends.Adopting this structure to make, two bearings 8 are effective effectively separates with extraneous working environment, prevent dust, particle enters in bearing 8 and accelerate it and wear and tear, thus effectively can improve the service life of bearing 8.As shown in Figure 1, wherein overcoat 4 is made up of outer sleeve 4-2 and the rubber layer 4-1 being fixed on outer sleeve 4-2 outer surface, and described outer sleeve 4-2 has keyway.Inner sleeve 3 outer surface known to Fig. 1 also has keyway, and outer sleeve 4-2 and inner sleeve 3 are connected by the key 6 be embedded in keyway.When the damage of ductile iron pipe internally coated lining support roller needs repairing, this structure is easy to just overcoat 4 to be dismantled and changed.Meanwhile, the right-hand member of inner sleeve 3 is provided with stepped protruding 10 of annular, and the other end is provided with the hold-down ring 11 of the annular that can freely dismantle, and this hold-down ring 11 coordinates with projection 10 and compresses overcoat 4, more convenient and swift.The outer surface of rubber layer 4-1 as shown in Figure 1 has the radiating groove 5 of 2 V-arrangements, in the present invention, this V-arrangement radiating groove 5 effectively adds the area of dissipation of rubber layer 4-1, can enable because fricative heat sheds timely and effectively, avoid because temperature constantly raises the danger damaging rubber layer 4-1; Meanwhile, V-arrangement radiating groove has certain spatial joint clearance, can meet the distortion that rubber layer 4-1 produces because of expanded by heating, prevents the squeezed bad danger of rubber layer 4-1 expansion.It should be noted that at this, although the quantity of the V-arrangement radiating groove shown in Fig. 1 is 2, as long as be provided with V-arrangement radiating groove for the present invention on the outer surface of rubber layer 4-1.
