Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1, the present invention provides a workpiece transportation device, which comprises a traveling mechanism, a bottom plate 21, a lifting mechanism, a top plate 22 and a slewing bearing 3, which are connected in sequence from bottom to top. The running mechanism drives the conveying device to move front and back, left and right, the lifting mechanism drives the top plate 22 and the rotary bearing 3 to move up and down, the outer ring of the rotary bearing 3 is installed on the top plate 22, and the inner ring of the rotary bearing is connected with a connecting part required by workpiece carrying according to requirements and used for adjusting the direction of the workpiece to be conveyed.

As shown in fig. 1 and 2, the traveling mechanism includes a crawler belt 1, a driving wheel 11, a rotation driving device 12, a guide wheel 13, a thrust wheel 14, and a frame 15, the rotation driving device 12 is preferably a rotating motor, and an output shaft of the rotating motor is connected to the driving wheel 11 through a reducer to rotate the driving wheel 11. Preferably, the running mechanism further comprises a battery 4, and the battery 4 supplies power to the rotating motor to meet the cruising requirement of the running mechanism. The driving wheels 11 and the guide wheels 13 are respectively provided at both ends of the crawler 1, and the bogie wheels 14 are provided below the frame 15. The person skilled in the art can also adopt structures such as wheels and axles which can also realize the walking function as the walking mechanism according to the needs.

The lifting mechanism comprises a lifting support 2 with a scissor fork mechanical structure and a hydraulic cylinder 24, and the scissor fork mechanical structure can enable the lifting of the lifting support 2 to have high stability and increase the bearing capacity of the lifting support, so that workpieces with large mass can be safely and stably transported. Specifically, a bottom plate 21 is arranged between the walking mechanism and the lifting mechanism, a hinge seat 23 is arranged on one side of the bottom plate 21, and the bottom of the lifting support 2 is arranged on the bottom plate 21. The lifting mechanism further comprises a hydraulic cylinder 24, the cylinder body of the hydraulic cylinder 24 is hinged with the hinge seat 23, and the output end of the hydraulic cylinder is connected with the connecting rod on the inner side of the lifting support 2.
