Abstract
The invention discloses a belt roller, and relates to the technical field of manufacture for mechanical equipment. The belt roller comprises a cylindrical base layer. An abrasion-resistant plate layer covers the outside of the cylindrical base layer; the abrasion-resistant plate layer is a composite steel plate with a surface layer made of chromium carbide hard alloy; the abrasion-resistant plate layer comprises two half cylinders and is firmly welded on the surface of the cylindrical base layer; weld holes are formed in the abrasion-resistant plate layer, plug welding can be performed on the cylindrical base layer via the weld holes, and the weld holes are filled by means of seal welding, so that the abrasion-resistant plate layer can be firmly welded with the surface of the cylindrical base layer, can be further fixedly connected with the cylindrical base layer and can be prevented from being broken. The belt roller has the advantage that problems of poor abrasion resistance of the surface of an existing roller and short service life of the existing roller can be solved.
Description
Technical field
The present invention relates to mechanical equipment manufacturing technology field, especially a kind of for delivery of the cylinder on belt feeder.
Background technology
Belt conveyer is iron and steel enterprise's significant transportation equipment, is widely used in the conveying of lump ore, sintering deposit, coke (powder).Cylinder is one of belt feeder major part, generally is divided into drive roll, driven cylinder, bend pulley.The resistance to abrasion of cylinder be to affect the in-use performance of cylinder and the key factor in life-span, and resistance to abrasion generally is decided by the cylinder surface material.According to material and processing mode, the cylinder main Types has at present: (1) cast iron, cast steel class: this class cylinder is after casting, by being machined to as finished product; (2) general steel plate class: this class cylinder is with carrying out surface finish after the steel plate roll-forming or by being machined to as finished product; (3) compound type: the outside face parcel one deck elastomeric material in above-mentioned three kinds of materials becomes finished product.
There is following problem in the cylinder of above-mentioned three types:
1) the material resistance to abrasion is all poor, and the cylinder life-span is very short, as is used in iron and steel enterprise, and the life-span only has 3-6 month usually.
2) belt roller of compound type, although after the damage of encapsulate layer, the off-line repair time is shorter, be splashed to the material of belt inside face in the Belt Conveying process, easily be bonded on the encapsulate layer, destroys the belt inside face, reduces the service life of belt.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of belt roller, and it can solve cylinder surface and wear no resistance, cylinder short problem in service life.
In order to address the above problem, technical scheme of the present invention is: this belt roller includes cylinder basic unit, in described cylinder basic unit, is coated with wear-resisting flaggy.
In technique scheme, more specifically scheme can also be: described wear-resisting flaggy is the clack steel plate that top layer has hard alloy; This wear-resisting flaggy is comprised of two semicircular cylinders and welds on described cylinder substrate surface.
Further: on described wear-resisting flaggy, be provided with for the access hole with the plug welding of described cylinder basic unit.
Further: described clack steel plate is the clack steel plate that top layer has the chrome carbide hard alloy.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1, the present invention adopts steel plate cylinder outer cladding top layer that the wear-resisting steel plate of chrome carbide hard alloy wear-resisting layer is arranged, and during belt roller work, hard alloy abrasion-resistant layer contact with belt, makes cylinder extend to 8-10 times of other material belt rollers service life; Alleviate the abrasion of belt simultaneously.
2, the present invention adopts semicircular cylinder wear plate and belt roller body contact portion additionally to have welding hole, for plug welding, the welding hole sealing weld is filled and led up, and further fixedly wear-resistant sleeve is connected with belt roller basic unit, prevents the wear-resistant sleeve fracture; Therefore stable and reliable for performance.
The accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Fig. 2 is A-A generalized section in Fig. 1.
Fig. 3 is that in the present invention, wear-resisting flaggy launches schematic diagram.
Number in the figure is denoted as: 1, cylinder basic unit; 2, wear-resisting flaggy; 3, bevel for welding; 4, access hole.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
The belt roller of Fig. 1, include cylinder basic unit 1, in cylinder basic unit 1, is coated with wear-resisting flaggy 2; There are the clack steel plate of chrome carbide hard alloy, the high-abrasive material that at the wear-resisting flaggy 2 of other embodiment, can also adopt surface to contain one or more layers other abrasion resistant alloys in wear-resisting flaggy 2 employing top layers; Wear-resisting flaggy 2 is comprised of two semicircular cylinders, and junction, two semicircular cylinder both sides offers bevel for welding 3, by bevel for welding 3 places welding, wear-resisting flaggy 2 is welded on cylinder basic unit 1 surface; On wear-resisting flaggy 2, offer for the access hole 4 with 1 plug welding of cylinder basic unit simultaneously, fill and lead up access hole by sealing weld, its layer 1 surface of wear plate 2 and cylinder is welded, further to fix the connection of wear-resisting flaggy 2 and its layer of cylinder 1, can prevent wear-resisting flaggy 2 fractures simultaneously.
The present invention carries the belt conveyer of the materials such as lump ore, sintering deposit, coke (powder) for iron and steel enterprise, because the belt roller surface is wear-resisting clack steel plate, one or more layers abrasion resistant alloy is contained on the clack steel plate surface, during work, the abrasion resistant alloy face contacts with belt, having solved cylinder surface wears no resistance, cylinder short problem in service life, also alleviated belt abrasion simultaneously.
