Description
Technical field
The utility model belongs to mine equipment technical field, relates to a kind of sealing arrangement, is specifically related to a kind of preventing side running of belt conveyer carrying roller.
Background technology
Belt feeder is the abbreviation of belt conveyer, and it is the continuous conveyor making material carrying and driving component with flexible load-transfer device.Belt feeder is with an end to end load-transfer device around head roll and bend pulley, and the upper inferior division between two cylinders is respectively with some idler stands, and material is placed in top set, utilizes the friction force traction load-transfer device between head roll and band and material to run.At present, conventional deflection preventing support roller is generally the straight carrying roller of a joint, the triple belt service direction of belt feeder is inconsistent, the straight carrying roller of one joint cannot meet its requirement, thus the damage causing carrying roller regular, more can not meet the requirement preventing belt deviation, greatly have impact on the fortune coal efficiency of underground belt conveyor, and bring very large potential safety hazard to the safety in production in colliery.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provide a kind of preventing side running of belt conveyer carrying roller, it is reasonable in design, structure is simple, has the cylinder that more piece is free to rotate, stable and reliable operation, long service life, productive costs is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of preventing side running of belt conveyer carrying roller, comprising at least two for the cylinder of back-up belt machine belt conveyor and the rotating shaft for installing described cylinder, it is characterized in that: also comprising multiple for preventing coal ash from entering the seal ring of driving surface and multiple back-up ring for preventing described seal ring from getting loose; Described rotating shaft is rotatablely equipped with at least two described cylinders, the bearing for reducing rotary resistance is provided with between each described cylinder two ends and described rotating shaft, described rotating shaft is positioned at outside described bearing and is set with described seal ring and described back-up ring all successively, all being installed with the jump ring for preventing described back-up ring from getting loose outside each described back-up ring, between adjacent described jump ring and described back-up ring, being provided with pad.
Above-mentioned preventing side running of belt conveyer carrying roller, is characterized in that: described bearing is antifriction-bearing box.
Above-mentioned preventing side running of belt conveyer carrying roller, is characterized in that: described jump ring is fixedly mounted in described rotating shaft by the draw-in groove be arranged in described rotating shaft.
Above-mentioned preventing side running of belt conveyer carrying roller, is characterized in that: described seal ring is O type rubber seal.
The utility model compared with prior art has the following advantages:
(1) design of this preventing side running of belt conveyer carrying roller is very reasonable, simple and compact for structure, has the cylinder that three joints are free to rotate, meets the requirement of preventing side running of belt conveyer.
(2) this preventing side running of belt conveyer carrying roller makes carrying roller operation stability and reliability all be greatly improved, long service life.
(3) production technology of this preventing side running of belt conveyer carrying roller is simple, and requirement on machining accuracy is not high, and a lot of parts are convenient to produce and buy all very much, and thus its productive costs is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
A kind of preventing side running of belt conveyer carrying roller as shown in Figure 1, comprising at least two for the cylinder 5 of back-up belt machine belt conveyor and the rotating shaft 1 for installing described cylinder 5, also comprising multiple for preventing coal ash from entering the seal ring 6 of driving surface and multiple back-up ring 4 for preventing described seal ring 6 from getting loose; Described rotating shaft 1 is rotatablely equipped with at least two described cylinders 5, cylinder 5 quantity preferably three.The bearing 7 for reducing rotary resistance is provided with between each described cylinder 5 two ends and described rotating shaft 1, described rotating shaft 1 is positioned at outside described bearing 7 and is set with described seal ring 6 and described back-up ring 4 all successively, all being installed with the jump ring 2 for preventing described back-up ring 4 from getting loose outside each described back-up ring 4, between adjacent described jump ring 2 and described back-up ring 4, being provided with pad 3.
In the present embodiment, described seal ring 6 is O type rubber seal, and described bearing 7 is antifriction-bearing box.
In the present embodiment, described jump ring 2 is fixedly mounted in described rotating shaft 1 by the draw-in groove be arranged in described rotating shaft 1.
The working process of the utility model preventing side running of belt conveyer carrying roller is: first this preventing side running of belt conveyer carrying roller is arranged on control position, and more piece independently cylinder 5 freely can be rotated in rotating shaft 1, and the rotation direction often saving cylinder 5 is determined by the belt conveyor of belt feeder.Seal ring 6 can effectively prevent coal ash from entering bearing 7 inside simultaneously, and seal ring 6 also can effectively prevent the lubricating grease of bearing 7 inside from leaking, thus effectively prevents bearing 7 premature failure.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
