Problems solved by technology

In some occasions, especially when these circular workpieces are assembled, it is required to hoist the circular workpiece horizontally, that is, the end face of the circular workpiece is in a horizontal position, and the sling cannot contact the lower surface of the circular workpiece, nor can it Affects the contact between the lower surface of the circular workpiece and the mating surface, and most of the circular workpieces cannot be provided with lifting holes on the outer peripheral surface, so how to lift these circular workpieces has become a difficult problem in mechanical installation and assembly

Embodiment Construction

[0014] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 2 , 3 As shown, the hoisting tool for the circular workpiece with grooves on the outer peripheral surface includes a ring 1, the inner diameter of the circular ring 1 should be greater than the outer diameter of the circular workpiece, when the size of the circular workpiece is small, the The circular ring 1 can be designed as an integral structure. When the size of the circular workpiece is large, the circular ring 1 can be welded by several arc-shaped plates or welded by multiple thin plates to form a combined structure. Two cylindrical main lifting lugs 2 and two plate-shaped auxiliary lifting lugs 3 are arranged on the ring 1, the two main lifting lugs 2 are arranged oppositely, and the two auxiliary lifting lugs 3 are arranged oppositely, A hoisting hole 31 is provided. The main lifting lug 2 is used as the main...

Abstract

The invention discloses a hoist tool for a round piece with a groove on a periphery surface, which comprises a ring with an inner diameter larger than the outer diameter of the round piece, wherein the periphery surface of the ring is provided with more than two radial thread through holes; and a bolt is arranged in the thread through hole. The hoist tool of the structure realizes the supporting of the round piece through extending the bolt into the peripheral groove of the round piece, thereby achieving the aim of horizontally slinging the round piece; the hoist tool can not contact to the lower surface of the round piece and can not cause influence on the assembly of the lower surface of the round piece and the coordinated surface of the round pieces, and quickens the speed of assembling and mounting machinery.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a hoisting tool for circular workpieces with grooves on the outer peripheral surface. Background technique [0002] In the production process, sometimes it is necessary to lift some circular workpieces. The structure of these circular workpieces is as follows: figure 1 As shown, there are more than one circle of circumferential grooves 11 on the outer cylindrical surface of the circular workpiece 10 . In some occasions, especially when these circular workpieces are assembled, it is required to hoist the circular workpiece horizontally, that is, the end face of the circular workpiece is in a horizontal position, and the sling cannot contact the lower surface of the circular workpiece, nor can it It affects the contact between the lower surface of the circular workpiece and the mating surface, and most of the circular workpieces cannot be provided with lifting holes on the outer peripheral surfa...
