Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supporting a roller in a belt conveyor.

[0002]

BACKGROUND OF THE INVENTION Belt bearing rollers in conventional belt conveyors are supported on a bed which traverses the belt at right angles and secures the ends of the bed to opposite sides of a frame.

[0003] The method of fixing the bed to the frame is to match the through holes provided in the bed and the frame,
Then, a bolt is inserted through the through hole, and then a nut is screwed into the bolt.

[0004]

When the above-described roller supporting method is employed, when the belt discharging belt conveyor accompanying the excavation of the tunnel is mounted on one side of the drill hole, the side surface of the belt conveyor and the peripheral side surface of the drill hole are provided. Since there is no room for an operator to enter between the two, the operation of fixing the end of the bed on the peripheral side of the hole of the belt conveyor cannot be performed.

[0005] The same applies to a case other than a tunnel, for example, when one side of a belt conveyor approaches a wall surface of a factory.

Therefore, an object of the present invention is to provide a belt conveyor in which the end of the bed can be extremely easily attached to the conveyor frame even if there is no room for an operator to enter on one side of the belt conveyor. It is to provide a roller support device.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to extend an endless belt between the front and rear pulleys, and to attach both ends of the belt support rollers to both sides of the frame. In the belt conveyor, one end of the roller support bed is fitted into and engaged with an engagement portion provided on one side of the frame, and the other end of the bed is provided so as to coincide with the other side of the frame. A structure is adopted in which the fastening fitting is inserted through the through hole and the bed is fixed to the frame by fastening the fitting.

[0008]

After the bed is inserted so as to cross the frame, the engaging portion of the frame and the engaging portion of the bed are fitted and engaged.

Next, the through hole of the frame is made to coincide with the through hole of the bed, and the fastener is inserted through the matched through hole.
Attach the bed to the frame by tightening the bracket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the accompanying drawings.

A belt conveyor A shown in FIG. 1 is composed of an endless belt 1 which is passed between front and rear pulleys (not shown), and a roller 2 which supports a carrier side and a return side of the belt 1.

The roller 2 has a center roller on the bed 3 on the carrier side, and side rollers arranged on both sides of the center roller, each of which is inclined upward and outward (as shown in FIG. 2). And
On the return side, one roller is mounted on the bed 3 (as shown in FIG. 1).

Further, one side of the frame 4 of the belt conveyor A, ie, for example, a side close to the peripheral side wall when the belt conveyor A is disposed close to one side of the peripheral side wall of a tunnel excavation site, and a frame crossing the frame 4. At one end of the bed 3 to be inserted from the other side of the bed 4, there is provided an engaging portion 5 which is fitted and engaged.

The above-described engaging portion 5 is, in the illustrated case,
Of the support piece 6 fixed to one end of the support piece 6 by welding or the like and a fitting hole 8 of the projecting shaft 7 provided on the frame 4 provided in the frame 4. May be provided.

After the fitting engagement between the protruding shaft 7 and the fitting hole 8, the bed 3 is aligned with the other end of the bed 3 and the through hole 9 provided on the other side of the frame 4, and then matches the matching through hole. After inserting the bolt of the fastener 10 into the hole 9, a nut is screwed into the bolt and the bed 3 is attached to the frame 4 by tightening.

The belt conveyor A extends the belt in the digging direction as the tunnel is dug, inserts the bed 3 every time the belt is extended, and attaches the bed 3 to the frame 4.

[0017]

As described above, according to the roller supporting device in the belt conveyor according to the present invention, the bed is inserted so as to cross the belt, and the engagement provided at the insertion end of the bed and one side of the frame. And the other end of the bed is fastened to the other side of the frame by a fastener inserted into the corresponding through-hole, so that there is room for workers to enter one side of the belt conveyor. It is very easy to mount the roller bearing bed to the frame even in the field.
