Description

The carrying roller of Novel belt conveyor

Technical field

The utility model belongs to the accessory technical field of the belt conveyor for material transmission, more particularly to a kind of novel The carrying roller of belt conveyor.

Background technique

Belt conveyor is low with manufacturing cost, easy for installation, conveying distance is long and the advantages such as maintenance is easy are widely used in The materials transportation art such as mine, metallurgy, harbour and storage.Belt is held up in belt conveyor as the long-term continuous operation of needs Numerous carrying rollers be belt conveyor core component, the service life of carrying roller and realize that quick-replaceable is that can belt conveyor The principal element of safe operation.

Currently, most of mine carrier roller of belt conveyer are all made of following structures, including carrying roller ontology, central axis and bearing Seat and bearing, bearing block include outer end face and end face, include inner ring and outer ring in bearing, generally between bearing block and outer retaining ring It is provided with sealing ring.Since the both ends of central axis extend to carrying roller outer body, in the connection of central axis and idler shell Place has gap, and dust or liquid material is easy to cause to enter, and the service life of the carrying roller of this metal structure is shorter, if mill Damage is serious when needing to overhaul or update, it is necessary to and it is that conveyer is out of service, with directly affecting mine haulage system production efficiency.

In addition, since sealing ring with central axis does not stop to rub, so that causing to generate gap between sealing ring and mandrel quickly And dust or steam is caused to enter Bearing inner, the function of rotation is just lost after bearing rust so that entire carrying roller is scrapped.

Summary of the invention

In order to overcome existing carrying roller not wear-resisting, it is easy to damage the defects of, the utility model provides a kind of conveying of novel band The carrying roller of machine, which can not only improve the wear-resisting property of carrying roller, corrosion-resistant, also mitigation carrying roller weight, be easily installed, extend support Roller service life.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel band of the utility model is defeated Send the carrying roller of machine, including carrying roller ontology, central axis and bearing block, central axis is through in carrying roller ontology and extending to carrying roller ontology Outer surface left and right ends, bearing block are mounted between carrying roller ontology and support shaft, and bearing block includes outer end face and inner face, It is characterized in that: being coaxially provided with the roller set of polyethylene wearproof complex abrasion-proof in carrying roller body outer surface, the polyethylene wearproof is multiple It closes wear-resisting roller set to be made of roller set I and roller set II, the roller set I is designed to knot compatible with carrying roller outer body Structure, top are mutually fastened with carrying roller body upper part, lower end be inserted between carrying roller ontology and bearing block inner face interconnecting piece it is rear with Central axis is mutually abutted against, and is equipped with locating piece between roller set I and central axis and bearing block；

Positioning sleeve is equipped on the outer end face of the bearing block, the roller set II is designed to the outer end face with bearing block I fixed company is covered with the roller of bending structure compatible outside positioning sleeve, and the outer end face top of the upper end and bearing block of roller set II It connects, the lower end of roller set II is mutually abutted against with central axis.

The central axis use it is intermediate be it is hollow, both ends are solid central axis, and at both ends apart from end 200mm It is a to be equipped with groove 7.

The ditch groove width is 35mm, thickness 2mm.

The utility model has the beneficial effects that since in carrying roller body outer surface to be coaxially provided with polyethylene resistance to for the utility model Grind the roller set I of complex abrasion-proof, can while guaranteeing carrying roller pressure-bearing, meanwhile, improve carrying roller wear-resisting property, production structure is simple It is single and light-weight, it is easily installed construction.Simultaneously as being provided with the roller of polyethylene wearproof complex abrasion-proof in bearing block outer end face Set II, two axle sleeves form new sealing structure to central axis and carrying roller ontology, to greatly prolong the service life of carrying roller.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1, a kind of carrying roller of Novel belt conveyor of the utility model, including carrying roller ontology 1, central axis 8 With bearing block 4, central axis 8 through in carrying roller ontology 1 and carrying roller body outer surface left and right ends are extended to, install by bearing block 4 Between carrying roller ontology 1 and central axis 8, bearing block 4 includes outer end face 9 and inner face 10, it is characterised in that: in carrying roller ontology 1 Outer surface is coaxially provided with the roller set of polyethylene wearproof complex abrasion-proof, and the roller set of the polyethylene wearproof complex abrasion-proof is by roller set I 2 It is formed with roller set II 3, the roller set I 2 is designed to compatible structure, top and carrying roller ontology 1 with 1 outside of carrying roller ontology Top mutually fastens, lower end insertion carrying roller ontology and 10 interconnecting piece of bearing block inner face between it is rear be abutted against with 8 phase of central axis, and Locating piece 6 is equipped between roller set I 2 and central axis 8 and bearing block 4；

Positioning sleeve 5 is equipped on the outer end face 9 of the bearing block, the roller set II 3 is designed to outer with bearing block The compatible bending structure in end face 9 and 5 outside of positioning sleeve, and the roller set on 9 top of outer end face of the upper end and bearing block of roller set II 3 I 2 are fixedly welded, and the lower end of roller set II 3 is abutted against with 8 phase of central axis.

Further, central axis 8 described in the utility model uses intermediate to be hollow, and both ends are solid central axis, this The central axis of kind structure is light-weight, is easily installed construction, meanwhile, cost is also reduced, and at central axis both ends apart from end 200mm are equipped with groove, and the ditch groove width is 35mm, thickness 2mm, are conducive to bearing block positioning in this way.

The design of the utility model polyethylene wearproof complex abrasion-proof roller set not only overcomes bearing sealed ring in the prior art With itself wear problem of central axis, also have extremely strong dustproof and waterproof function, reliable guarantor is provided to bearing guard block Card, to also greatly improve the protecting effect to bearing.
