Description
Technical field
The present invention relates to nuclear power station field, and in particular to a kind of anti-fall device of pressure vessel installation and debugging.
Background technology
Nuclear reactor pressure container is the closed container for disposing nuclear reactor and bearing its huge operating pressure, and also referred to as core is anti-
Heap pressure vessel is answered, is the key equipment in pressurized-water reactor nuclear power plant, with manufacturing technology standard is high, difficulty is big and the spy such as cycle length
Point, and be non-exchange equipment, it is necessary to assure it is perfectly safe reliable in lifetime of the nuclear power station more than 40 years.
Installed in the nuclear island of nuclear power station with debugging process, nuclear reactor pressure container is being installed, in-pile component, master are installed
When bolt hole cleaning, cold examination and heat examination etc., all there is very high requirement to cleannes.But, due to the flange face of pressure vessel
Drop away from pressure vessel bottom plate is very big, typically can all exceed 9m, if protection is not in place, is often fallen in the presence of pendant thing, personnel
Potential safety hazard.In current nuclear power station work progress, have no special equipment and ensure above-mentioned construction activities safety, it is necessary to which workman enters
Pressure vessel laid inside anti-drop net prevents the article, personnel from crashing into pressure vessel.But during practice of construction, nuclear reactor pressure
Force container volume is larger, and construction cost and the increase of anti-drop net cost can be brought by laying large-scale anti-drop net, while workman's laying is anti-fall
Hanging operation can be carried out during net, there is higher potential safety hazard.In addition, existing anti-drop net is network, lay anti-fall
It is less than the junk of its grid after net for volume, can not be accepted, junk still can be fallen to inside pressure vessel, is influenceed
Normally using after operation.
The content of the invention
It is an object of the invention to provide a kind of anti-fall device of pressure vessel installation and debugging, to solve in the prior art
When carrying out installation and debugging to pressure vessel there is potential safety hazard, while the undertaking of anti-drop net limited in one's ability is asked in laying anti-drop net
Topic, realizes the purpose for reducing potential safety hazard, improving undertaking ability.
The present invention is achieved through the following technical solutions：
A kind of anti-fall device of pressure vessel installation and debugging, including framework, the framework by the vertical support bar of N roots,
And the connecting rod composition of N root support bars is connected in bottom, the lower portion is provided with anti-drop net, and anti-drop net is connected to support bar
On, wherein N is the integer more than or equal to 3；Junk groove is additionally provided with immediately below the anti-drop net, the junk groove is also connected to
On support bar；The top of every support bar is fixedly connected with a suspension ring.
During for carrying out installation and debugging to pressure vessel in the prior art there is potential safety hazard, while anti-fall in laying anti-drop net
The problem of undertaking of net is limited in one's ability, the present invention proposes a kind of anti-fall device of pressure vessel installation and debugging, including by supporting
The framework that bar and connecting rod are constituted, connecting rod is in the bottom of support bar, for each support bar to be connected as into an overall structure, the branch
Strut is vertically arranged, for providing enough height, while being that anti-drop net and junk groove provide mount point and stress point for framework.

There is anti-drop net, anti-drop net is connected on support bar.Junk groove is additionally provided with immediately below the anti-drop net, junk groove is also connected to
On support bar, the junk of the small volume dropped from the grid on anti-drop net can be fallen to downwards in junk groove, so as to upper
The object that portion drops carries out final undertaking, it is to avoid the object dropped is dropped down onto inside pressure vessel, so as to solve existing face
When the anti-fall sieve bottom that hangs there is the problem of object of many mesh, small volume can drop from mesh.In addition, every branch
The top of strut is fixedly connected with a suspension ring, for whole framework to be lifted by crane.During use of the present invention, lifted by
Put and hook suspension ring framework is hoisted to inside pressure vessel, framework is being placed in pressure vessel installation and debugging operating area just
Lower section, carries out installation and debugging operation afterwards.The object dropped in operation process or the staff fallen can drop anti-
Pendant is online, and the object of small volume can also drop in junk groove, so as to realize protective action.The present invention is integral type knot
Structure, can repeat to use, while frame size can be arranged as required to as less structure, so that anti-fall web area
Also smaller, as long as ensure that the underface of operating area can be caught, solving traditional anti-drop net needs entirety
Laying, the problem of area is big, cost is high；The present invention only needs progress handling to use simultaneously, it is not necessary to which workman is vacantly in pressure vessel
The interior installation for carrying out anti-drop net, largely reduces the potential safety hazard of operating personnel.
It is preferred that, the support bar side is provided with vertically equally distributed hook, and the anti-drop net is set in
On hook.Be support bar side in the uniform multiple hooks of vertical short transverse, anti-drop net is set on hook, consequently facilitating
The height of anti-drop net is adjusted as needed, realizes that anti-drop net high flexible is adjustable, anti-drop net can be torn open from hook
The purpose unloaded.
It is preferred that, the support bar, connecting rod are made by solid metallic lead.Metallic lead has in common metal
Larger quality, therefore support bar and connecting rod are made using solid metal lead, it is that whole framework uses solid metal lead system
Into to improve frame mass, the intensity and bearing capacity of raising framework.
It is preferred that, the support bar, connecting rod are integrally formed, and the welding hook is on support bar.It is whole framework one
It is body formed, it is ensured that framework is consolidated.Simultaneously by welding hook, it is ensured that hook can carry anti-drop net, it is ensured that use safety.
It is preferred that, the bottom surface of the junk groove is equipped with sponge.Sponge material soft texture and flexible, falls to
Object in thing groove can be dropped on sponge, consumed the kinetic energy of junk by the soft and flexible characteristic of sponge,
So as to avoid junk from occurring fierce collision, it is to avoid outside object bullet to junk groove, avoid causing damage of colliding with to junk trench bottom
It is bad.
The present invention compared with prior art, has the following advantages and advantages：
A kind of anti-fall device of pressure vessel installation and debugging of the present invention, including the framework being made up of support bar and connecting rod,
Connecting rod is in the bottom of support bar, and for each support bar to be connected as into an overall structure, the support bar is vertically arranged, for for
Framework provides enough height, while being that anti-drop net and junk groove provide mount point and stress point.Lower portion is provided with anti-fall
Net, anti-drop net is connected on support bar.Junk groove is additionally provided with immediately below the anti-drop net, junk groove is also connected to support bar
On, the junk of the small volume dropped from the grid on anti-drop net can be fallen to downwards in junk groove, so as to be dropped to top
Object carry out final undertaking, it is to avoid the object dropped is dropped down onto inside pressure vessel, existing is hung temporarily so as to solve
Anti-fall sieve bottom there is the problem of object of many mesh, small volume can drop from mesh.In addition, every support bar
Top is fixedly connected with a suspension ring, for whole framework to be lifted by crane.
