Description
[technical field]
The utility model relates to nuclear power service technique field, in particular to a kind of taper lifting lug is oriented to column assembly.
[background technique]
Nuclear reactor Qinshan Phase II NPP second phase, refueling outage year, when reactor core in-pile component lifts, guide post is essential
, the generally circular in cross section lifting lug of the lifting lug of existing guide post hangs that in-pile component is especially difficult, and precision is difficult to slap in nuclear reactor
Hold, accidentally suspended object will directly weight pole on round lifting lug, cause equipment damage, industrial risk is especially big, in order to
Guarantee that in-pile component safely and smoothly lifts, it is necessary to propose a kind of taper lifting lug guiding column assembly.
[utility model content]
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of taper lifting lug guide post group
Part, the purpose is to solve the problems, such as to hang in-pile component difficulty in nuclear reactor in the prior art.
To achieve the above object, the utility model proposes a kind of taper lifting lug be oriented to column assembly, including taper lifting lug and
Guide post, the taper lifting lug are equipped with through-hole, and the bottom end of the taper lifting lug is equipped with stud, and the top of the guide post is equipped with
Screw hole corresponding with stud, the main body of the guide post are equipped with a groove, and the bottom end of the guide post is equipped with a step,
The bottom end of the step is equipped with sealing ring.
Preferably, the guide post is stainless steel products.
Preferably, the apex angle of the taper lifting lug is 60 °, the taper lifting lug is stainless steel products.
Preferably, the stud is equipped with left-handed external screw thread, left-handed internal screw thread is equipped in the screw hole.
Preferably, the cross section of the groove is semicircle.
Preferably, the diameter of section of the sealing ring is larger than the diameter of section of step bottom end.
The utility model has the beneficial effects that the utility model is bolted guide post and taper lifting lug composition
One entirety further assists hanging in-pile component in nuclear reactor by the apex angle on taper lifting lug, compared with prior art, this
Utility model structure is simple, and design rationally, can be convenient and efficiently carry out lifting work, task difficulty greatly reduces, and contracts
The short working time, reduce industrial risk.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of taper lifting lug guiding column assembly of the utility model embodiment.
In figure: 1- taper lifting lug, 11- through-hole, 12- stud, 2- guide post, 21- screw hole, 22- groove, 23- step, 24-
Sealing ring.
[specific embodiment]
To make the objectives, technical solutions and advantages of the present invention clearer, below by accompanying drawings and embodiments,
The present invention will be further described in detail.However, it should be understood that specific embodiment described herein is only used to solve
The utility model is released, the range being not intended to limit the utility model.In addition, in the following description, being omitted to known features
With the description of technology, to avoid the concept for unnecessarily obscuring the utility model.
Refering to attached drawing, the utility model embodiment provides a kind of taper lifting lug guiding column assembly, including taper lifting lug 1 and leads
To column 2, the taper lifting lug 1 is equipped with through-hole 11, and the bottom end of the taper lifting lug 1 is equipped with stud 12, the top of the guide post 2
End is equipped with screw hole 21 corresponding with stud 12, and the main body of the guide post is equipped with a groove 22, the bottom of the guide post 2
End is equipped with a step 23, and the bottom end of the step 23 is equipped with sealing ring 24, and the guide post 2 is stainless steel products, the taper
The apex angle of lifting lug 1 is 60 °, and the taper lifting lug 1 is stainless steel products, and the stud 12 is equipped with left-handed external screw thread, described
Left-handed internal screw thread is equipped in screw hole 21, the cross section of the groove 22 is semicircle, and the diameter of section of the sealing ring 24 is wanted
Slightly larger than the diameter of section of 23 bottom end of step.
Utility model works process:
A kind of taper lifting lug guiding column assembly of the utility model during the work time, is hung when needing to carry out reactor core in-pile component
When dress, first the stud 12 on taper lifting lug 1 can be screwed in screw hole 21, the lifting rope of loop wheel machine is then passed through into through-hole 11, then
Guide post 2 is transported to above guide post mounting groove by loop wheel machine, the step 23 in guide post 2 is then embedded into guide post peace
In tankage, the installation of guide post 2 is completed, the lifting of in-pile component is assisted finally by the taper lifting lug 1 in guide post 2, this
Utility model structure is simple, and design rationally, can be convenient and efficiently carry out lifting work, task difficulty greatly reduces, and contracts
The short working time, reduce industrial risk.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
