Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shaft part transportation, and in particular to a lifting appliance for transporting shaft parts. BACKGROUND

[0002] The lifting appliance refers to a device for lifting heavy objects in hoisting machinery. In order to realize the mass and rapid transportation of shaft parts, a lifting device is usually used for transportation. Since the surface of the planet gear after preliminary processing does not have a lifting hole and a lifting lug and other lifting structures, it is not convenient to use a lifting hook to cooperate with the lifting device for lifting. The permanent magnet lifter is a kind of hoisting equipment that uses high-performance permanent magnet materials to generate strong magnetic force and can attract and transport steel workpieces without external power supply. It is widely used in mechanical manufacturing, steel processing, logistics transportation and other fields, and has the characteristics of energy saving, safety and high efficiency.

[0003] For the related technology in the above, the inventor believes that during the processing of the planet gear, the end face needs to be processed, and after being lifted onto the processing table, the planet gear needs to be adjusted to a vertical state. The above-mentioned permanent magnet lifter cannot guarantee that the shaft metal part is in a vertical state during lifting, and the magnetic force will be applied to the shaft part during transportation. The shaft part needs to be demagnetized during processing, otherwise it will affect the precision of the shaft part and increase the processing steps of the shaft part. In addition, the surface of the shaft part is in a smooth cylindrical shape, and the contact area with the permanent magnet lifter is small during adsorption, and the lifting process is unstable. Therefore, the permanent magnet lifter is only suitable for products with low precision processing requirements, reducing the lifting applicability of the shaft part. SUMMARY

[0004] In order to realize the vertical stable lifting of the shaft part, the present application provides a lifting appliance for transporting shaft parts.

[0005] The lifting appliance for transporting shaft parts provided by the present application adopts the following technical scheme: A lifting appliance for transporting shaft parts, comprising a base ring and a locking assembly, a lifting hole is formed on the circumference of the base ring, the lifting hole penetrates through the two sides of the base ring in the axial direction, a plurality of lifting holes are formed on the base ring, and the locking assembly for fixing the shaft part is arranged on the base ring.

The plurality of lifting holes are connected with the lifting device, and the columnar part can be lifted vertically during lifting, which facilitates the processing of the end face of the columnar part in the subsequent operation.

[0008] By adopting the above technical solution, the lifting ring is placed on the outside of the columnar part, and is threadedly connected to the first threaded hole and the second threaded hole using a locking bolt until the inner ring wall of the base ring is tightly pressed against the outer wall of the columnar part, thereby achieving stable clamping of the part.

When the two lifting half-rings are closed, the sliding pressure blocks on the two lifting half-rings contact each other, and the sliding pressure blocks squeeze the extrusion liquid sac. Under the squeezing action of the extrusion liquid sac, several stabilizing arc blocks move toward the direction close to the central axis of the lifting half-ring.

[0014] By adopting the above technical solution, when connecting the two lifting half rings, the rotating locking rod is rotated, and the rotating locking rod is rotated into the connecting side groove of the other connecting side plate.
