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
The present invention relates to a kind of hoist tool, particularly a kind of hoist tool for establishing reeded round work on the outer peripheral face.
Background technology
Some round works of sometimes will slinging in process of production, the structure of these round works have circumferential recess 11 more than the circle at the periphery cylinder of round work 10 as shown in Figure 1.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 affect 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 the mechanical erection assembling.
Summary of the invention
For 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 for reeded round work on the outer peripheral face, it comprises an internal diameter greater than the annulus of 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: should be used for the hoist tool of 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, then rotate the bolt in the tapped through hole, bolt head is extend in the circumferential recess of round work, and the head that the upper limb of round work circumferential recess is pressed in bolt when drawing annulus is like this realized 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 of mechanical erection.
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, the hoist tool that should be used for reeded round work on the outer peripheral face comprises an annulus 1, 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 larger, 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 at 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 the 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.
Should be used for the hoist tool of reeded round work on the outer peripheral face before use, first bolt 4 slightly be screwed out, and generally bolt 4 was threaded to its head and not expose from the annulus inner peripheral surface and get final product.Then this hoist tool of slinging 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 the upper side edge of round work circumferential recess by bolt and realizes 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 of mechanical erection.
More than the hoist tool that is used for reeded round work on the outer peripheral face that the embodiment of the invention is provided be described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; all will change in specific embodiments and applications; 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.
