Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for a roller conveyor that floats and supports frames on both sides of a ladder-like roller conveyor to convey the same.

Roller conveyors are often used while being placed on the ground, and when they are moved, they are lifted and carried directly by human power. However, roller conveyors are quite heavy and require an extremely bent position to lift them, which puts a heavy burden on the lower back and causes lower back pain.

The present invention was developed by focusing on the above-mentioned conventional problems.The lever is swung in an almost upright position, and the cams integrated with this lever push up and levitate the frames on both sides of the roller conveyor. The purpose of the present invention is to solve the above-mentioned problems by providing a transportable structure.

Embodiments of the present invention will be described below with reference to the figures. Two casters 2, 2 are attached to the lower portions of the pair of opposing bases 1, respectively, so as to be freely pivotable. Support plates 3, 3 are vertically fixed to the insides of both bases 1, respectively. And both bases 1, 1 support plate 3,
They are connected by a connecting bar 4, which is a connecting member installed between the upper parts of the parts 3 and 3.

The pair of levers 5, 5 have lower ends pivotally attached to the inside of each support plate 3 by a shaft 6, and upper ends connected by a handle 7. The lever 5 is swingable, but is stopped by contacting the stopper 8 on the base 1 in the upright position shown by the solid line in FIG. It will be done.

A pair of cam plates 9, 9 are provided at the inner end of the bearing sleeve 10 supporting the shaft 6 at the lower end of each support plate 3, parallel to the lever 5, and spaced apart therefrom. It is fixed. The cam plate 9 swings together with the lever 5.

When the lever 5 is in the upright state, the cam plate 9 is inverted, as shown by the solid line in FIG. It can be inserted from the end of the frame 21. Further, when the lever 5 is in the collapsed state, the cam plate 9 is in the upright state shown by the imaginary line in FIG. Supportable.

When the cam plate 9 is in the upright state, the first and second protrusions 9a and 9b are arranged substantially horizontally, and the first protrusion 9a is positioned beyond the perpendicular line A passing through the center of the shaft 6. It is located.

Next, the action will be explained. This conveyance device is installed and used at both ends of the roller conveyor 20 in the longitudinal direction. With the lever 5 erected as shown by the solid line in FIG. 2 and the cam plate 9 laid down as shown by the solid line in FIG. 9 is inserted into the lower part of the protruding piece 21a of the frame 21. Next, the lever 5 is swung down to a position where it contacts the connecting bar 4, as shown by the phantom line in FIG. 2, and the cam plate 9 is simultaneously raised to the position shown by the phantom line in FIG. As the cam plate 9 rises, the frame 21 of the roller conveyor 20 rests on the protrusions 9a and 9b and rises from the ground. At this time, the first protrusion 9a reaches a position beyond the perpendicular line A passing through the center of the shaft 6, so the cam plate 9 does not reverse rotation even if left alone due to the rotational moment. For safety, lock screws 11 are screwed into each support plate 3.
This also makes it possible to lock the lever 5 from swinging.

As explained above, in the present invention, a cam is inserted into the lower part of the projecting piece 21a on the outside of the frame of the roller conveyor by the swinging of the lever 5 which is pivotably mounted on the base 1 equipped with the caster 2. Since the roller conveyor 20 is configured so that it can be transported in a state in which the plate 9 is rotated upright and the roller conveyor 20 is floated, the roller conveyor 20 can be transported with extremely simple and effortless operation.
The effect is that it can be floated and easily transported.

Claims (1)

[Scope of Claim for Utility Model Registration] A pair of opposing bases each having a caster at the bottom thereof, spaced apart from each other on the outside of both frames of a roller conveyor, and connected by a connecting member; a pair of levers connected to each other, the lower ends of which are pivotally connected to the levers; and a projecting piece of the frame on both sides of the roller conveyor, which is located coaxially with the pivot axis of these levers and is fixed to the inside of each lever at a spaced interval. A roller conveyor conveyance device comprising a pair of opposing floating cams which can be inserted into the lower part and whose tops can be raised by swinging of the lever to push up and hold protrusions on both sides of the roller conveyor.
