Description

Technical Field

[0001] The utility model relates to a hoop device, in particular to a multi-stage flipping hoop device. Background Art

[0002] At present, for the rolling operation of some large objects in the market, it is mainly carried out by placing them on a rolling frame, and the shapes of these objects are basically standard circular objects. When rolling operations need to be carried out on some irregular objects, due to the non-circular outer contour shape, they cannot be placed on the roller frame for rolling operations.

[0003] For some large objects with high requirements for the outer surface, when placed on the rolling frame for rolling, due to direct contact with the rollers of the rolling frame, it is inevitable to leave rolling marks or even cause damage to the outer surface. Later, it is necessary to remove the marks or repair the objects, resulting in a waste of human resources.

[0004] Since the hoop device is generally used on large objects, its own volume is also large. In terms of transportation, large vehicles are required for transportation, resulting in a waste of transportation resources; in terms of storage, it also occupies a large amount of space; on narrow roads, it is not convenient to pass through. Summary of the Utility Model

[0005] Aiming at the problems in the background art, the utility model provides a multi-stage flipping hoop device, which can wrap irregular objects into a circular shape and roll them on a rolling frame, and can be applicable to different working conditions.

[0006] The technical solution for achieving the purpose of the utility model is: a multi-stage flipping hoop device, including a lower hoop, a right middle hoop, an upper right hoop, a left middle hoop, an upper left hoop and a flipping adjustment structure. One end of the lower hoop is hinged to one end of the right middle hoop, and the other end is hinged to one end of the left middle hoop. The other end of the right middle hoop is hinged to one end of the upper right hoop, and the other end of the left middle hoop is hinged to one end of the upper left hoop. The flipping adjustment structure is used to adjust the right middle hoop to flip around the lower hoop, the upper right hoop to flip around the right middle hoop, the left middle hoop to flip around the lower hoop, and the upper left hoop to flip around the left middle hoop. When the hoop device is closed, the other end of the upper right hoop contacts the other end of the upper left hoop to wrap the object into a circular shape.

[0007] Further, the flipping adjustment structure includes a lift and a motor.

[0008] Further, the lift adopts a worm and worm gear lift.

[0009] Further, there are 4 sets of the flipping adjustment structures, which are respectively installed between the lower hoop and the right middle hoop, the right middle hoop and the upper right hoop, the lower hoop and the left middle hoop, and the left middle hoop and the upper left hoop.

[0010] Furthermore, the worm and worm gear lift includes a base and a telescopic rod. The base is hinged to one of the hoops, and the telescopic rod is hinged to the other hoop. Driven by the motor, the corresponding telescopic rod is controlled to extend and retract, so that one hoop makes a flipping motion relative to the other hoop.

[0011] Furthermore, the hinge is a pin hinge.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: This device can wrap irregular objects into a circular shape and roll on a rolling frame; when used on large objects with high requirements for the outer surface, the hoop device is used to isolate the outer surface of the object from the rolling frame, and at the same time, the purpose of rolling on the rolling frame can be achieved; by designing a multi-stage flipping mechanism, after folding the hoop, the volume is reduced to facilitate transportation and storage, and at the same time, it has good passability (easy to pass through the door frame).
