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

The hoist tool that is used for reeded round work on the outer peripheral face
Technical field
The present invention relates to a kind of hoist tool, particularly a kind ofly be used for the hoist tool that outer peripheral face is provided with the round work of groove.
Background technology
Some round works of sometimes will slinging in process of production, the structure of these round works as shown in Figure 1, in the circumferential recess 11 that has on the periphery cylinder of round work 10 more than the circle.In some occasion, particularly when these round works assemble, requirement level this round work of slinging, be that the round work end face is horizontal, and suspender can not contact with the lower surface of round work, therefore how can not influence the lower surface of round work and contacting of mating surfaces, and lifting hole(eyelet) can't be set on the outer peripheral face of most round work, these round works be lifted by crane a difficult problem when becoming machinery assembling being installed.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provide a kind of can the very convenient hoist tool that reeded round work on the outer peripheral face is lifted by crane.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of hoist tool that is used for reeded round work on the outer peripheral face, it comprises the annulus of an internal diameter greater than the round work external diameter, the outer peripheral face of described annulus is provided with plural radially tapped through hole, is provided with bolt in the described tapped through hole.
Preferably, described annulus is provided with two columned main hangers, and described two main hangers are oppositely arranged.
Preferably, described annulus is provided with two tabular auxiliary hangers, and described two auxiliary hangers are oppositely arranged, and described auxiliary hanger is provided with hole for hoist.
Preferably, the head of described bolt is round table-like.
Preferably, the afterbody of described bolt is provided with square toes.
Technique scheme has following beneficial effect: this hoist tool that is used for reeded round work on the outer peripheral face in use, at first annulus is passed round work, and circumferentially the position of groove is corresponding on the position that makes tapped through hole and the round work, rotate the bolt in the tapped through hole then, bolt head is extend in the circumferential recess of round work, like this last when drawing annulus the upper limb of round work circumferential recess be pressed on the head of bolt and realize lifting.The hoist tool of this structure is by stretching into bolt the support that realizes in the round work circumferential recess round work, thereby the purpose that is up to the standard and slings this round work, this hoist tool can not touch the lower surface of round work, can the assembling of round work lower surface and mating surfaces not impacted yet, accelerated the speed that mechanical assembling is installed.
Description of drawings
Fig. 1 is the structural representation of round work.
Fig. 2 is the front view of the embodiment of the invention.
Fig. 3 is the birds-eye view of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
Shown in Fig. 2,3, this is used for, and the hoist tool of reeded round work comprises an annulus 1 on the outer peripheral face, the internal diameter of this annulus 1 should be greater than the external diameter of round work, when the round work size hour, this annulus 1 can be designed to integral structure, when the round work size was big, this annulus 1 can be welded or be become unitized construction by the polylith light gauge welding by the several piece arc.Be provided with two columned main hangers 2 and 3, two main hangers 2 of two tabular auxiliary hangers are oppositely arranged on annulus 1, two auxiliary hangers 3 are oppositely arranged, and auxiliary hanger 3 is provided with hole for hoist 31.As the main stress hanger, auxiliary hanger 3 generally is used for non-productive operations such as position adjustment to main hanger 2 when handling.
The outer peripheral face of annulus 1 is provided with plural tapped through hole, tapped through hole is evenly distributed on the outer peripheral face of this annulus 1, be provided with bolt 4 in the tapped through hole, the head car of bolt 4 becomes than smaller round table-like of the core diameter of thread, round platform is as the position of bearing pressure, round work can not be pressed in the screw position of bolt, avoids screw thread to be damaged by pressure.The afterbody of bolt 4 is provided with square toes, is convenient to the rotation of bolt 4.The size of bolt 4 depends on the width of round work circumferential recess, and the quantity of bolt 4 depends on the quality of round work and the intensity of bolt itself.
This hoist tool that is used for reeded round work on the outer peripheral face screws out bolt 4 earlier before use slightly, generally bolt 4 is threaded to its head and does not expose from the annulus inner peripheral surface and get final product.This hoist tool of slinging then makes annulus 1 pass round work from top to bottom, adjusting position to bolt 4 aims at the circumferential recess of round work, then bolt 4 is screwed out, bolt 4 is stretched in the circumferential recess of round work, and back-out length can fully contact with the upper limb of round work circumferential recess with bolt 4 head round platforms and be as the criterion.This moment, whole hoist tool was stuck in the round work circumferential recess by bolt 4, at last by driving, draw main hanger 2 on the steel rope, the upper limb of round work circumferential recess is pressed on the head round platform of bolt 4 can realizes lifting.
The hoist tool of this kind structure mainly supports realization by bolt to the upper side edge of round work circumferential recess the level of this round work is sling, this hoist tool can not touch the lower surface of round work, can the assembling of round work lower surface and mating surfaces not impacted yet, accelerated the speed that mechanical assembling is installed.
More than be used for to the embodiment of the invention provided that the hoist tool of reeded round work is described in detail on the outer peripheral face; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
