Abstract
The utility model relates to a forerake up-down roller device for a V-shaped belt. The utility model is composed of a hanger, a roller supporting seat, a roller, and a cross beam. An included angle is formed between the axis of the roller and the horizontal plane of the cross beam at a vertical direction, and a front rake is formed between the axis of the roller and the vertical plane of the cross beam at a horizontal direction, which reduces the tension when the groove type for a belt is changed to the flat type, or the flat type is changed to the groove type, generates the acting force of the deviation rectifying for the belt, and stabilizes the normal running for the belt. The utility model has the advantages of simple structure, convenient maintenance, low cost, and good deviation rectifying effect.
Description
The utility model belongs to belt transporter belt deviation rectifying device.
At present, the method for correcting error of belt transporter is a lot, carrying roller lifts roller, V-type carrying roller, self-centering idler, groove profile carrier roller etc. up and down, the method of portion and swelling device place automatic deviation correction is rare end to end but to being used for belt transporter, above-mentioned carrying roller is used for belt transporter, and the effect of portion and swelling device place correction is not good yet end to end, and belt tension force when taking turns end to end is bigger.
The purpose of this utility model be to provide a kind of reduce belt when taking turns end to end tension force and to the belt transporter V-shape belt of portion and the swelling device place automatic deviation correction upper and lower supporter roller arrangement that leans forward end to end.
The technical solution of the utility model be achieved in that the utility model comprise hang, idler stand seat, carrying roller, crossbeam form, hang, the idler stand seat is welded on the crossbeam, its structural feature is in the bayonet socket on the unsettled idler stand seat that is installed in the crossbeam outside of carrying roller, the axis of carrying roller and the horizontal surface of crossbeam have an angle in vertical direction, and the axis of carrying roller and the vertical surface of crossbeam have a front rake in the horizontal direction.
After adopting such structure, the utility model is installed in the position of taking turns end to end near belt transporter, has reduced belt and has become the tension force that flat pattern or flat pattern become grooved by grooved.Because carrying roller has a front rake and at vertical surface one angle arranged at the horizontal surface of belt, produced a application force again, stablized belt and normally moved belt deviation rectifying.The utility model is simple in structure, and is easy to maintenance.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is that the lean forward master of snub pulley device of the utility model V-shape belt looks scheme drawing.
Fig. 2 is that the utility model V-shape belt snub pulley device that leans forward is removed the birds-eye view of carrying roller.
Fig. 3 is the lean forward left view of snub pulley device of the utility model V-shape belt.
Fig. 4 is the lean forward structural representation of upper supporting roller device of the utility model V-shape belt.
Fig. 5 is the utility model V-shape belt stressed scheme drawing of upper and lower supporter roller arrangement that leans forward.
The utility model V-shape belt shown in Figure 1 lean forward the snub pulley device comprise hang 1, idler stand seat 2 and 4, carrying roller 3, crossbeam 5 form, the utility model V-shape belt snub pulley device that leans forward is fixed on the frame of belt transporter by hanging 1, hang 1, idler stand seat 2 and 4 is welded on the crossbeam 5, the horizontal surface of the axis of carrying roller 3 and crossbeam 5 has an angle in vertical direction, and angle b is 5 degree.Carrying roller shown in Figure 23 is unsettled to be installed in the bayonet socket 7 on the idler stand seat 2 and 4 in crossbeam 5 outsides,, the vertical surface of the axis of carrying roller 3 and crossbeam 5 has a front rake in the horizontal direction, and angle a is 3 degree.Shown in Figure 3 hanging has arrow mark 6 on 1, the direction of arrow mark 6 is consistent with the direction that belt advances when installing to show.Figure 4 shows that the lean forward structure of upper supporting roller device of the utility model V-shape belt, this device is fixed on the frame of belt transporter by adapter plate 8.When belt shown in Figure 5 moved, belt drove the carrying roller uniform rotation to the friction force F of carrying roller, and carrying roller also has an antagonistic force F to belt
Instead, F
InsteadCan be decomposed into F
Instead* Cosa and F
Instead* Sina (a is the carrying roller front rake), F
InsteadThe direction of * Sina is pointed to the line of centers (being centering thrust) of belt, when belt to the left during sideslip, because the area of contact of left side carrying roller and belt is greater than the area of contact of right side carrying roller and belt, this moment, belt equated the pressure of left and right sides carrying roller, so propelling thrust left that the propelling thrust to the right that the left side carrying roller produces belt produces belt greater than the right side carrying roller, under the effect of this thrust difference, belt moves right automatically, when the propelling thrust that belt is produced up to left and right sides carrying roller equates, belt will stably move.At belt self tension force and carrying roller under the double action to the thrust difference of belt, realized belt feeder self can be at any time to the running state correction of belt.
