Abstract
The present invention relates to an automatic bidirectional offset-correcting carrier roller controlled by a brake, which is composed of a carrier roller and at least one brake arranged on one end of the carrier roller, wherein the brake is composed of a sliding shaft, a sliding bearing, a dynamic friction sheet, a free friction plate and a static friction sheet, the sliding shaft is formed by extending a carrier roller shaft, the dynamic friction sheet, the free friction plate and the static friction sheet are orderly sheathed on the sliding shaft, and a offset-correcting thruster supported by the bearing is arranged on a sliding shaft sleeve. The present invention has the advantages of compact structure, sensitive response, reliable motion and automatic offset-correcting of belts running in a reciprocating way.
Description
One, technical field
The present invention relates to a kind of belt load transfer device, especially a kind of automatic bidirectional offset-correcting carrier roller that is used on the band conveyor.
Two, background technology
Belt deviation is to hinder the normal key of using of band conveyor always, also is the difficult point that engineering staff need study and solve for a long time.Traditional method for correcting error is that upright shelves roller is set in the belt both sides of conveyer, prevents belt deviation passively.Recently also the someone proposes the power of the sideslip belt felt by upright shelves roller, drives roller rack and rotates an angle, reaches the purpose of correction.Above-mentioned various scheme is normally used guaranteeing the belt load transfer device, has brought into play many effects, but has also had some problems really, by the passive sideslip that prevents of upright shelves roller, very easily quickens the wearing and tearing of belt edge, reduces belt service life, very easily draws bad belt in the time of seriously.The transmission by power of thirty years of age grade of roller drives roller rack and rotates an angle, though can in time rectify a deviation, because the transmission device complexity, reaction is sensitive inadequately, and because of long term exposure in the dust pollution serious environmental, very easily be stuck.
Three, summary of the invention
1, goal of the invention: the objective of the invention is to: at the present situation that prevents the belt deviation technology at present, propose a kind of compact conformation, the automatic bidirectional offset-correcting carrier roller of sensitive drg control.
2, technical scheme: the object of the present invention is achieved like this: a kind of automatic bidirectional offset-correcting carrier roller of drg control, form by carrying roller, it is characterized in that: the end at carrying roller is provided with drg at least, and the concrete structure of drg is as follows: roller carrier shaft is stretched to the outer vertically, formed slide shaft; Slide shaft is suit sliding shaft sleeve, dyanainic friction sheet, free Friction disk, static Friction disk successively from inside to outside; The sliding shaft sleeve center is provided with and the identical hole of slide shaft section geometric figure, and slide shaft is provided with the correction propelling unit of bearings.
3, beneficial effect: the invention has the advantages that: compact conformation, be quick on the draw, reliable in action, no matter belt both forward and reverse directions operation all can realize automatic deviation correction.
Four, description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the embodiment that an end is equipped with drg;
Fig. 3 is the application of embodiment in flute profile carrying roller group that an end is equipped with drg;
Fig. 4 is the embodiment that two ends are provided with drg;
Fig. 5, Fig. 6 are several slide shaft section embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the invention is further described.
As seen from Figure 1, the present invention is made up of carrying roller 1, at least the end at carrying roller 1 is provided with drg, the structure of drg is: roller carrier shaft is stretched out vertically, form slide shaft 2, outwards be set with sliding shaft sleeve 3, dyanainic friction sheet 4, free Friction disk 5, static Friction disk 6 on the slide shaft 2 from the lining successively.The correction propelling unit 8 that bearing 7 supports is housed on sliding shaft sleeve 3.
As seen from Figure 2, in order to prevent the stuck drg of dust, present embodiment is being done further technical finesse on the basis of Fig. 1: carrying roller is taken over 9 running-fits between carrying roller 1 and correction propelling unit 8, in the present embodiment, and catcher 9 and carrying roller 1 synchronization action.In addition, add dust boot 10, dyanainic friction sheet 4, free Friction disk 5, static Friction disk 6 are covered in wherein.In order to make belt edge promote the propelling unit 8 of rectifying a deviation like a cork, present embodiment is set up a spring 11 between carrying roller 1 axle center and sliding shaft sleeve 3.
Fig. 3 is the application of embodiment in groove profile carrier roller that an end is provided with drg.In addition, the deviation-adjusting carrier roller of this structure can also use in " V " type carrying roller.
As seen from Figure 4, the brake structural of this embodiment is identical with the embodiment that Fig. 2 provides, its difference only is: with spring shown in Figure 2 11 by moving on between carrying roller 1 axle center and the sliding shaft sleeve 3 between friction of rest sheet 6 and the sliding shaft sleeve 3, this be because: the automatic bidirectional offset-correcting carrier roller that two ends are provided with drg generally is used in the flat idler, in case belt deviation, after the propelling unit of will rectifying a deviation is pushed outer ledge to, impossible return, can only be by the power of spring 11, make its return (in the embodiment shown in Figure 2, its return is the gravity by correction propelling unit 8 and sliding shaft sleeve 3).
Fig. 5 and Fig. 6 have provided the geometric embodiment of section of two kinds of slide shafts 2 respectively.
The present invention is in real work, in case belt deviation, must promoting to rectify a deviation, the edge is close laterally for propelling unit 8, and dyanainic friction sheet 4, free Friction disk 5 and static Friction disk 6 be squeezed in one, friction increases, correction propelling unit 8 rotary resistances on the drg are strengthened, under the belt effect that is in operation, directly drive angle of deviation-adjusting carrier roller rotation the correction of the belt of sideslip is come.
In the various embodiments described above, dyanainic friction sheet 4 is and is installed on the correction propelling unit 8, and in addition, dyanainic friction sheet 4 also can be a smooth operation face of correction propelling unit 8.
