Abstract
The utility model discloses a kind of heap core shell upper backup pad and lift special 3 hanging beam structures.3 hanging beam structures are fixing by high-strength bolt docking by two semicircle welding box body mechanisms, and inside is reinforced by bearing pin, and 3 three, hanging beam structure bottom otic placodes are connected with the lifting earclip bearing pin above upper backup pad in heap core shell by adjustable drawbar.This utility model uses sectional type attachment structure form; two semi-circular structure are attached by high-strength bolt; sufficiently large frictional force is provided to bear shear-type load; and semi-circular structure internal connection uses bearing pin to connect; play the purpose of Redundancy Design; even if connecting bolt destroys due to external condition, the internal bearing pin that connects plays a protective role without there is lifting accident.Box-type section structure be conducive to carrying upper and lower suspension centre is inconsistent and the local bending moment that produces.And the design of semicircle split meets the dimensional requirement of highway transportation.
Description
Technical field
This utility model relates to nuclear industry mechanized construction technical field, particularly relates to the lifting of heap core shell upper backup pad special
3 hanging beam structures.
Background technology
Along with the development of China's nuclear power technology, technology is the most ripe, and current Construction of Nuclear Electricity is the most in the world
Carry out.In Construction of Nuclear Electricity engineering, the lifting of pressure vessel metal stack inner member heap core shell is the heaviest of nuclear industry mechanization process
The step wanted, and the lifting of heap core shell upper backup pad is also related to quality and the safety of whole engineering.Patent of the present invention is according to mesh
Front practical situation, the whole intensity of hanging beam structure, the requirement of stability and hanging beam group when meeting lifting heap core shell upper backup pad
The highway transportation of part requires to set out, and designs 3 hanging beam structures of a kind of new structure form, it is achieved heap core shell upper backup pad
Lift in place.
Utility model content
This utility model is in Construction of Nuclear Electricity needed for pressure vessel metal stack inner member heap core shell upper backup pad lifting operation
Hanging beam structure, for main supporting body.Its 3 hoisting structures meet 3 lifting ears above heap core shell upper backup pad
The layout of button, intensity when box-structure itself strengthens lifting and stable, sectional type design meets the highway of each parts
Movement requirement.
This utility model provides a kind of heap core shell upper backup pad and lifts special 3 hanging beam structures.3 hanging beam structures by
Two semicircle welding box body mechanisms are fixing by high-strength bolt docking, and inside is reinforced by bearing pin, 3 hanging beams knots
Three, structure bottom otic placode is connected with the lifting earclip bearing pin above upper backup pad in heap core shell by adjustable drawbar.
Wherein, four otic placodes of 3 hanging beam structure upper are connected with the suspension hook of crane with steel wire rope by shackle,
Wherein, four, top otic placode with four, bottom otic placode not on vertical straight line.
Beneficial effect: this utility model uses sectional type attachment structure form, and two semi-circular structure pass through high-strength bolt
It is attached, it is provided that sufficiently large frictional force bears shear-type load, and semi-circular structure internal connection uses bearing pin to connect, and rises
To the purpose of Redundancy Design, even if connecting bolt destroys due to external condition, internal connect bearing pin play a protective role and
Lifting accident will not occur.Box-type section structure be conducive to carrying upper and lower suspension centre is inconsistent and the local bending moment that produces.And half
Circle split design meets the dimensional requirement of highway transportation.
Accompanying drawing explanation
The heap core shell upper backup pad that Fig. 1 provides for this utility model embodiment lifts special 3 hanging beam structure charts.
Fig. 2 this this utility model embodiment lifting heap core shell upper backup pad figure.
Accompanying drawing identifies: 1, bearing pin；2, semicircle welding box body mechanism；3, adjustable drawbar；4, heap core shell upper backup pad.
Detailed description of the invention
For making this utility model solve the technical problem that, the technical scheme that uses and the technique effect reached clearer,
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.It is understood that it is described herein
Specific embodiment is used only for explaining this utility model, rather than to restriction of the present utility model.It also should be noted that, for
It is easy to describe, accompanying drawing illustrate only the part relevant to this utility model rather than full content.
Special 3 the hanging beam structures of heap core shell upper backup pad lifting that the present embodiment provides use integral ring-shaped box-type section
Version designs, and whole hanging beam considers transportation clearance, is divided into two semicircle welding box body mechanisms, two semicircle casing welderings
Being attached by high-strength bolt before connection mechanism, the semicircle in-house junction of welding box body uses bearing pin to connect, and rises
To the purpose (playing the effect of shear stress of bearing when the frictional force deficiency that high-strength bolt is formed) of Redundancy Design, bearing pin
It is designed to meet single bearing capacity.Owing to top is that four-point structure is connected with suspension hook, bottom use bikini structure with
Heap core shell upper backup pad connects, it is impossible to transmit point-to-point for load, and designed box-structure possesses carrying due to suspension centre
The inconsistent and local bending moment that produces, it is achieved lifting operation.
With reference to Fig. 1-2,3 hanging beams are docked together by two semicircle welding box body mechanisms 2 by high-strength bolt, interior
Portion is additionally added bearing pin 1 and reinforces.Four, hanging beam top otic placode is connected with the suspension hook of crane with steel wire rope by shackle, bottom
Three otic placodes are connected with upper backup pad in heap core shell 4 lifting earclip bearing pin above by adjustable drawbar 3.Each connection member connects
After completing, by crane running, whole 3 hanging beams and heap core shell upper backup pad 4 are lifted by crane, adjust reactor core by adjustable drawbar 3
The degree of balance of shell upper backup pad 4, lifting is installed to specifying position.
Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand: the technical scheme described in foregoing embodiments is modified by it, or to the most some or all of technical characteristic
Carry out equivalent, do not make the essence of appropriate technical solution depart from the scope of this utility model each embodiment technical scheme.
