Description
Technical field
The present invention relates to nuclear energy equipment technical field, specifically a kind of gravity self-locking type storage vertical suspender of sleeve.
Background technology
Nuclear fuel storage screen work is the nucleus equipment in nuclear fuel cycle, is widely used in spentnuclear fuel in heap storage, centre
AFR storage and reprocessing plant storage.In recent years, with the Large scale construction of domestic nuclear power generating sets, China is to nuclear fuel storage
The demand of screen work is very big, but the domestic screen work used now relies on external import mostly, and not only the product supply of material is expensive,
And it is restricted on technology and delivery cycle.Therefore the production domesticization research work of nuclear fuel storage screen work, purchased for reducing
Cost, the construction of China's nuclear power engineering project is promoted to have great importance.
Nuclear fuel storage screen work, by the hollow square of tens of to up to a hundred individual 5 meters, section 229*229,2~2.5mm of thickness of length
Pipe storage sleeve composition, not only requires each spacing stored between sleeve, assembling sequence strict with the degree control of bottom plate
Strict installation requirement is wanted to perform.Assembling process will keep storing sleeve vertical state, and conventional method is to tie sleeve one with the rope made of hemp
Head, slowly lifting, bottom also need to personnel and helped at any time upwards, and operating efficiency is low, and has very big potential safety hazard.Therefore set
The gravity self-locking type storage vertical suspender of sleeve has been counted, has realized that storage sleeve is safely and reliably lifted by crane and loaded and unloaded.
Existing method is to tie one, sleeve with the rope made of hemp, and slowly lifting, bottom also need to personnel and helped at any time upwards, actual
Using mainly there is following three big shortcomings：
1. because rope made of hemp binding is not firm, lifting, movement can only be carried out slowly very much, and position the artificial tune of out of plumb needs
Whole, operating efficiency is low.
2. position inaccurate is assembled, it is difficult to ensure that the perpendicularity of assembling positioning requirements.
3. sleeve surface is very smooth, the rope made of hemp is bundled with possible loosening, and in order to keep vertical, bottom wants someone to help at any time
Hold, if operating personnel may be injured by a crashing object by coming off, there is very big potential safety hazard.
The content of the invention
It is an object of the invention to provide a kind of gravity self-locking type to store the vertical suspender of sleeve, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical scheme：
A kind of gravity self-locking type stores the vertical suspender of sleeve, including square tube, and the square tube is respectively installed with fixed company up and down
Joint chair, spreader assembly is provided between two fixed connecting base, the spreader assembly includes claw and movable rocking bar；Claw,
Movable rocking bar and two fixed connecting bases form four groups of slider-crank mechanisms；Moving up and down for upside fixed connecting base drives claw to receive
Contracting or tensioner.
As the further scheme of the present invention：Spring, the bullet are set with square tube between two fixed connecting base
Spring and fixed connecting base form spring_slide structure, realize the automatic dismantling function of suspender.Lifting state, claw is by storage sleeve
Action of Gravity Field, slider-crank mechanism makes fixed connecting base be made spring-compressed by downward active force；Covered when putting down storage
Cylinder, gravity release, and compression spring produces upward active force to upper fixed connecting base, and slider-crank mechanism makes claw inwardly receive
Tightly, tensioner is released.
As further scheme of the invention：Rocking bar is provided with square tube above the upside fixed connecting base, is shaken
Bar bottom is provided with cam, and the rocking bar is arranged in square tube by connecting rod and movable latch and forms cam mechanism, the side
Cam mechanism is corresponded on pipe and is provided with movable backing pin, ensure during the cam peak contact activity backing pin of cam mechanism on fixed connect
Joint chair will not upwards activity and drive claw inwardly to release tensioner state, so as to realize insurance function.
As further scheme of the invention：The square tube bottom endoporus tensioner and locking nut is provided with, and locked
Nipple heads are provided with monkey wrench, make square tube naturally vertical by gravity, positioning convenient for assembly.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention provides a kind of gravity self-locking type storage vertical suspender of sleeve, and structure is novel；The present invention uses crank block
Mechanism and spring_slide structure make suspender, and very easily tensioner and loose unloading, labor intensity of operating staff drop significantly in square tube
Low, operating efficiency greatly improves；The square tube bottom endoporus tensioner and locking nut is provided with, there is monkey wrench on head, passes through
Gravity makes square tube naturally vertical, positioning convenient for assembly；Other invention cam mechanism makes suspender in lifting shape vertically
State auto lock, prevent from conveniently dropping caused by miscellaneous part defect is possible, security greatly improves.
Brief description of the drawings
Fig. 1 is the structural representation that gravity self-locking type stores the vertical suspender of sleeve.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of gravity self-locking type storage vertical suspender of sleeve, including square tube, the square tube cover respectively up and down
Equipped with fixed connecting base 2, spreader assembly is provided between two fixed connecting base 2, the spreader assembly includes claw 4 and lived
Shake bar 5；Claw 4, the fixed connecting base 2 of movable rocking bar 5 and two form four groups of slider-crank mechanisms；Upside fixed connecting base 2
