Technical field
The invention belongs to nuclear power plant's Measuring error technical fields, and in particular to a kind of high temperature gas-cooled heap-type reactor pressure holds
The quick-connect machanism of device inspection.
Background technology
High temperature gas cooled reactor is to make cooling agent, the high nuclear reactor of outlet temperature with helium.In the support of national " 863 " plan
Under, from last century the eighties mid-term, China has carried out the research of high-temperature gas-solid two-phase flow, exploitation, the advanced nuclear energy system of forth generation
One of technology of system.The heap-type equally exists the nuclear reactor pressure container of similar presurized water reactor
(reactorpressurevessel).Reactor pressure vessel is placement nuclear reaction and bears the closed of its huge operating pressure
Container is the key equipment in HTGR Nuclear Power Plant, has the characteristics that manufacturing technology standard is high, difficulty is big and the period is long,
And it is non-exchange equipment, it is necessary to assure it is perfectly safe reliable in lifetime of the nuclear power station more than 40 years.
In nuclear power station operational process, reactor pressure vessel is in high temperature, high pressure, the high environment radiated.With operation
The increase of time, the metallicity of container material can continuously decrease, and metal discontinuity can also generate, so very it is necessary to right
Pressure vessel is detected, and to find defect risk therein in time, can be handled as early as possible, so as to safeguard and protect
Hinder the safety of nuclear power facility, avoid the occurrence of serious safe operation and nuclear leakage accident.
It is high radioactivity region inside container after nuclear reactor pressure container is run in power station, since high temperature nuclear reactor uses helium
Gas makees cooling agent, and there is no the characteristics of opening container unloading shutdown.The inspection of high temperature gas cooled reactor reactor pressure vessel is from container
Implement in outside.
In view of cylinder core region, radioactive dosage is higher after operation, and when inspection forbids under personnel to the heap outside cylinder
Core region, therefore entire check device can only use the sealing flange face installation positioning in reactor cabin, mechanical device is from cylinder
Implement to check, automatically moved to probe scanning device at cylinder any bar girth joint or longitudinal seam by motion guide rail in outside.
When equipment installation, inspection and troubleshooting, operating personnel only need station above cabin, without entering cylinder core region.
Summary situation needs to design a set of device of reactor pressure vessel inspection that with remote control can implement,
The world needs independently to set for the heap-type not about high temperature gas cooled reactor commercialization power station reactor pressure vessel Examined effect at present
A kind of nuclear power plant reactor pressure vessel check device is counted out, which implements to check outside pressure vessel, according to this
It checks embodiment, designs a kind of mechanism that can quickly connect.
Invention content
The object of the present invention is to provide a kind of reactor pressure vessel inspection quick-connect machanisms, can be directed to from pressure

In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:The unlocking board is equipped with locking spiral shell
Female shifting chute, interior to be equipped with lock screw, the lock screw coordinates with lock screw shifting chute sidewall thread, by unlocking board
It is fastened on the top of connection strap cavity.
In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:The connection strap cavity is cuboid
Shape, head rounded corner.
In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:The unlock guide groove is symmetrical with unlock
The center line of plate length direction, and bend certain angle to center position.
In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:Including elevating lever, connection strap and connection
Slot, the connection strap and link slot have two groups, every group of end for being located at elevating lever.
In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:The elevating lever selects square to cut
The aluminium alloy extrusions in face is made.
In a kind of above-mentioned reactor pressure vessel inspection quick-connect machanism:Gear is equipped in the lifting rod end surface
Plate.
The remarkable result of the present invention is as follows:Quick-connect machanism is combined by elevating lever, connection strap assembly, link slot.With
The mode of more piece splicing, realization quickly connect into long guideway, can also fast quick-detach, operating personnel may be located remotely from radioactivity ring
Border;The structure of connection strap band elasticity movable lug realizes that connection strap is inserted into link slot and compresses automatically, into link slot, moves to connection
Automatic spring during the empty window of slot.Realize quick insertion locking connection, it is simple and reliable for structure;The design of link slot both sides Perforated window,
Realize that the movable lug on connection strap is clamped in link slot, under the weight effect on elevating lever, auto lock is not in simultaneously
Surprisingly come off;Unlocking board is slided in design on connection strap, which realizes the dismounting of quick-connect machanism, while the locking of unlocking board
Nut design can prevent maloperation.

Specific embodiment
Below by the drawings and the specific embodiments, the invention will be further described.
As shown in Figure 1, the quick-connect machanism is made of elevating lever 12, connection strap 11, link slot 13.Elevating lever 13 is selected
The aluminium alloy extrusions of square section makes, and assembles connection strap 11 and link slot 13 respectively at the both ends of elevating lever 13, simultaneously
In section bar end face equipped with baffle, it can prevent connection strap 11 and link slot 13 from moving axially.Connection strap 11 and link slot 13 are in every section
Two are respectively installed on elevating lever 12, connection strap 11 and link slot 13 are respectively at both ends, while this Liang Tao bindiny mechanism is arranged symmetrically
In section bar both sides.
Connection strap structure as shown in Figures 2 and 3, including connection strap cavity 6, for cuboid shape, head rounded corner.
Two sliding slots 9 are symmetrically processed on connection strap cavity 6, spring bearer plate 10,10 liang of spring bearer plate are installed in described two sliding slots 9
Spring 7 is installed in side respectively, 7 end of the spring connection movable lug 1 per side, installs pin 2 on the movable lug 1,2 lower end of pin is located at
In above-mentioned sliding slot 9.When external force inwardly squeezes movable lug 1 from outside, the pin 2 on movable lug 1 is along sliding slot 9 inward against shifting
It is dynamic.
Unlocking board 5 is installed in the top of connection strap cavity 6, which is rectangular slab, and upper end symmetrically processes two
Item unlocks guide groove 5, which is symmetrical with the center line of 5 length direction of unlocking board, and bends certain angle to center position
Degree.Lock screw shifting chute 8 is machined in the lower end of unlocking board 5, it is interior that lock screw 4, lock screw 4 and lock screw are installed
8 sidewall thread of shifting chute coordinates, and unlocking board 5 is fastened on to the top of connection strap cavity 6.
Movable lug 1 can be contracted in inside connection strap cavity 6, while under external force extruding in the cavity under the action of spring 7
Nature is stretched out.There is the unlocking board 5 of slip in 11 upper surface of connection strap, pull the pin 2 on movable lug and realize that movable lug 1 is squeezed into
In connection strap cavity 6.
When the movable lug 1 of connection strap 11 is inserted into link slot 13, movable lug 1 is shunk under the extruding of groove body inner wall, later, movable lug 1
It stretches out, is stuck in the eating dishes without rice or wine of link slot 13 under the effect of spring 7, realize that docking is completed.
