DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier bed for a belt conveyor.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 9, a carrier bed 53 of a trough type belt conveyor, which supports a belt 52 by a pair of rollers 50 having inclined axes and a horizontal roller 51 located between them, Both ends of each roller 50, 51 are respectively supported by a stand 54, and the lower end portion of each stand 54 is fixed to a beam 55 extending in the width direction of the belt 52,
The beam 55 extends through the frame 5 in the length direction of the belt 52.
6 is detachably attached.

In the above carrier bed 53, when the rollers 50, 51 are damaged, the tension of the belt 52 is released, and then the height of both ends of the carrier bed 53 is increased as shown in FIGS. Lift the belt 52 above,
The connection between the beam 55 and the frame 56 is released, and the entire carrier bed 53 is removed from the frame 56 to remove the rollers 50, 5
Replace 1.

[0004]

However, in the case of a large conveyor for a long distance, since the belt and the carrier bed are very heavy, it is necessary to use a crane as shown in the figure, and it takes a great deal of labor to replace the rollers. It took time.

Therefore, an object of the present invention is to provide a carrier bed whose rollers can be easily replaced.

[0006]

In order to solve the above problems, the present invention provides a plurality of stands that support a belt with a plurality of rollers arranged in a trough type and that support both ends of each of the rollers. In a carrier bed of a belt conveyor, which is provided on a beam extending in the width direction of a belt, and the beam is supported by a frame extending in the belt length direction, the beam is an outer pipe, and an inner pipe slidably inserted into the outer pipe. The inner pipe is provided with a stand for supporting the roller whose axis is inclined to one side, the stand for supporting the other roller is provided for the outer pipe, and one end of the outer pipe and one end of the inner pipe are provided on the frame. This is because it is detachably attached.

[0007]

In the carrier bed according to the present invention, when the roller is replaced, the connection between the beam and the frame is released, and the outer pipe is pulled out from the inner pipe, so that the roller can be taken out from below the belt without lifting the belt. You can

Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIGS. 1 to 4, a carrier bed 1 according to the present invention supports a belt 5 by a pair of rollers 2 and 3 whose axes are inclined and a horizontal roller 4 located between them. Both ends of the roller 2 are on the stands 6 and 7, respectively, and both ends of the roller 3 are on the stands 8 and 9, respectively.
Both ends of the roller 4 are supported by stands 7 and 8, respectively. The lower ends of the stands 6, 7, 8 and 9 are supported by beams 10 extending in the width direction of the belt 5.

The beam 10 includes an outer pipe 11 and an outer pipe 1.
1 and the inner pipe 12 slidably inserted into the outer pipe 11.
Are connected by a tightening bolt 13 inserted from one end of the. The cross-sectional shape of the beam 10 is not limited to a quadrangle as shown in FIG. 3, and may be a circle or a triangle as shown in FIGS. 5 and 6.

A stand 9 for supporting the outer end of the roller 3 is provided on the inner pipe 12, and the other stands 6,
The outer pipes 7 and 8 are provided. It should be noted that the stand 8 may be divided into two, and the portion supporting the horizontal roller 4 may be provided in the outer pipe 11 and the portion supporting the roller 3 may be provided in the inner pipe 12.

A pair of facing engagement surfaces 15 are formed on the outer circumference of the shaft 14 projecting from both ends of each of the rollers 2, 3 and 4, and the shaft 14 is supported by the upper end portions of the stands 6, 7, 8 and 9. The shaft 14 is prevented from rotating and the rollers 2, 3 and 4 are positioned in the axial direction by dropping it into the notch 16 formed in the above and engaging the engaging surface 15 with the notch 16. Each roller 2, 3, 4 rotates about a shaft 14.

A connecting member 17 is attached to one end of the outer pipe 11 and one end of the inner pipe 12, and the connecting member 17 is detachably attached to a frame 18 extending in the length direction of the belt 5 with a fixing bolt 19. ing.

In the carrier bed 1 as described above, when the rollers 2, 3 and 4 are replaced, the tightening bolt 13 is loosened to disconnect the outer pipe 11 and the inner pipe 12. Then
As shown in FIG. 7, the fixing bolt 19 fixing the outer pipe 11 is removed, and the connection between the beam 10 and the frame 18 is released. When the outer pipe 11 is pulled out from the inner pipe 12, the rollers 2 and 4 can be taken out from below the belt 5 without lifting the belt 5. afterwards,
Fixing bolt 1 for fixing the inner pipe 12 as required
9 is removed, and the roller 3 is taken out.

Alternatively, as shown in FIG. 8, the fixing bolt 19 for fixing the inner pipe 12 may be removed first, the inner pipe 12 may be pulled out from the outer pipe 11, and the roller 3 may be taken out.

Even when the number of rollers is other than three, by providing a stand for supporting the roller whose axis is inclined to one side on the inner pipe 12 and a stand for supporting the other rollers on the outer pipe 11, Each roller can be taken out in the same manner as in the above embodiment.

[0016]

As described above, according to the present invention, the beam for supporting the roller is configured such that the inner pipe is slidably inserted into the outer pipe, and the outer pipe and the inner pipe are detachable from the frame. When exchanging the roller, the connection between the beam and the frame is released, and the outer pipe is pulled out from the inner pipe, so that the roller can be taken out from below the belt without lifting the belt and the roller can be easily exchanged.
