Specific embodiment

This utility model is described in detail below with reference to specific embodiment shown in the drawings.But these embodiment party Formula is not intended to limit this utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or Conversion functionally is all contained in protection domain of the present utility model.

Referring to Fig. 1 to Fig. 2, one embodiment of this utility model provides a kind of belt conveyor's pulley 100, cylinder 100 With axis X.

For the ease of describing and illustrating, it is defined as radially, being radially away from the direction of axis X perpendicular to the direction of axis X Be defined as it is outer, be radially defined as near the direction of axis X in, axis X place plane definition is vertical section, perpendicular to axis X Plane definition be cross section.

Cylinder 100 includes roll body 10, and is coated on the wearing plate 20 on 10 surface of roll body, by roll body 10 Surface coating wearing plates 20, when making ribbon conveyer work, belt is contacted with wearing plate 20, increases the wearability of cylinder 100 Can, extend the life-span of cylinder 100.

Wearing plate 20 is formed at some welding beads 23 on its outer surface 201, some welderings during being included in its welding fabrication Road 23 constitutes non-slip texture structure.So, the frictional force between belt and cylinder 100 can be increased by non-slip texture structure, is prevented Only belt slippage, be easy to draining；And, non-slip texture structure is made up of welding bead 23, makes granule materials because of 23 hardness of welding bead height Cannot be stuck between welding bead 23 and belt, it is to avoid damage belt, so as to extend the service life of belt；And welding bead 23 is wear-resisting Formed in 20 forming process of plate, without the need for extra processing technique, generation type simple and fast, reduce manufacture difficulty and be easy to scale Production.

Specifically, the non-slip texture structure may be configured as vertical bar stricture of vagina, horizontal stripe, inclined stripe, chevron or check.Attached In figure embodiment, the non-slip texture structure is horizontal stripe, namely the welding bead 23 is parallel to the axis X.

In the non-slip texture structure, in indent at 230 of having a common boundary, namely wearing plate 20 is in boundary for adjacent two welding beads 23 Thickness of the thickness at 230 compared with wearing plate 20 at welding bead 23 is little, wherein, at boundary 230, thickness is less than 23 interior thickness of welding bead 1mm or so.

Further, the width of welding bead 23 is set to 15 ~ 50mm.So, the functional contact face of belt and welding bead 21 can be made Product increase.

It is 3 ~ 5.5%, Cemented chromium carbide of chromium content 18 ~ 35% that the material of wearing layer 22 is set to carbon content, so, Its hardness can be made to be more than HRC 50.Further, the Cemented chromium carbide also include the nonmetalloid such as boron, nitrogen or titanium, One or more of the metallic elements such as niobium, vanadium, molybdenum, tungsten, zirconium, rare earth, to promote hard particles in wearing layer 22 to generate or refine, Wearability is improved further.

In addition, wearing plate 20 by stiff dough Welding make molding, in forming process can synchronous forming go out welding bead 23.

Further, in one embodiment of this utility model, wearing plate 20 may be configured as integrally formed sheet material and roll up System is coated on roll body 10, or may also be configured to be formed by splicing and combining after two and the sheet metal bending of the above.

In one embodiment of this utility model, wearing plate 20 is by being fixedly welded on roll body 10.Further, After roll body 10 is welded in, wearing plate 20 can also be fixed on roll body 10 by way of perforate plug welding, with further Strengthen the bonding strength between wearing plate 20 and roll body 10.Specifically, wearing plate 20 is provided with some welding holes 202, passes through Welding hole 202 is filled and led up in sealing weld, wearing plate 20 is welded with 10 surface of roll body, it is to avoid while coming off can mode wearing plate 20 break Split.

In other embodiments, wearing plate 20 can be also fixed on by screw connection manners such as such as countersunk head screw, plant oncomelania bolts On roll body 10.

Further, referring to Fig. 3 to Fig. 5, in one embodiment of this utility model, on the outer surface 201 of wearing plate 20 It is additionally provided with some dispersion welding beads 21.Dispersion welding bead 21 protrudes out outer surface 201 to disperse between welding bead 21 in adjacent two Groove is formed, granule materials are placed in groove, so as to or seldom will not compress belt energetically, protect belt not frayed, can Further enhance the non-skid property and drainage performance of cylinder.

Specifically, some dispersion welding beads 21 include some first welding beads 211 being parallel to each other and spacing is equal, mutually put down Row and equal some second welding beads 212 of spacing, the first welding bead 211 are 30 ~ 60 ° with the angle of axis X, the second welding bead 212 with The angle of axis X is 120 ~ 150 °, and the spacing of adjacent two the first welding beads 211 is equal to the spacing of adjacent two the second welding beads 212.

Referring to Fig. 3, further, the cross section of welding bead 21 is disperseed to be set to arch per bar, to strengthen dispersion welding bead 21 Structural strength.

Those listed above is described in detail and is only for illustrating for feasibility embodiment of the present utility model, it And be not used to limit protection domain of the present utility model, all equivalence enforcement sides made without departing from this utility model skill spirit Formula or change are should be included within protection domain of the present utility model.
