The present invention has overcome the defective of prior art, by original access lock design is revised, makes access lock all obtain improvement from safety, maintenanceability, ease for use and cost aspect.
In order to address the above problem, the present invention is achieved by the following technical solutions:
1. standard component such as motor and commutator reselects
What original access lock drive motors was selected for use is the servo buncher of brush DC.Its structure is complicated, and the also relatively more expensive and domestic motor that does not have similar model of price needs import.
The present invention is guaranteeing under the prerequisite that electric machine theory moment of torsion and rotating speed require, adopt asynchronous AC motor+frequency converter timing to replace original direct current generator, and, reduced alternating current generator heating and moment of torsion problem of unstable by increasing the means of forcing cooling, improved the reliability of motor.
Original access lock commutator is external buying, and the present invention has revised the interface of commutator in design on the basis of assurance function and reliability, selected homemade commutator for use.
By the type selecting again of motor and commutator, make original import equipment all adopt home equipment to substitute, thereby shortened the delivery cycle of equipment, greatly reduce purchase cost.
2. change relay and be controlled to be PLC control
Along with the fast development of electronic technology, programmable logic controller (PLC) (being called for short PLC) is widely applied at industrial control field.PLC is a kind of electronic system of digital operation operation, aims to use under industrial environment to manufacture and design.The operating principle of relay and PLC is different, and relay control device is the mode that adopts the hard logic parallel running, and no matter in which position of circuit, when the coil electricity or the outage of relay, all of this relay are got an electric shock can while action at once.The CPU of PLC (CPU) then adopts the method for operation of sequential logic scanning user program.Promptly when a logic coil was switched on or switched off, the contact of this coil can not moved at once, just can move in the time of must scanning this by the time.The main feature of PLC is that reliability height, abundant I/O interface, modular construction, installation are simple, easy to maintenance.At equipment debugging, when safeguarding, can utilize portable notebook computer to come the monitoring programme operation, or update routine, very directly perceived and convenient.
3. revise the equalizing valve hermetically-sealed construction
A flap type is all arranged on each doorframe of access lock, two valves are consistent with the seal request of hermatic door under the reactor operation operating mode, when door is opened, transmission mechanism is at first opened this valve, be that access lock cabin external and internal pressure balances each other, reduce the lateral force that produces because of pressure reduction, be convenient to the unlatching of door and prevent because pressure reduction damages personnel's health of turnover to door-plate.Originally the sealing surface of gate is a vertical plane, if the inside and outside pressure reduction greatly that exists of gate, sealing ring is easy to come off, thereby influences the sealing of gate.The present invention has revised the design of seal groove, has original rectangular seal groove to change dovetail groove into, guarantees that it can not come off, and is that the seal groove section area is more reasonable, and the sealing ring of having avoided the sealing ring excessive compression to cause lost efficacy.
4. revising positive coupling is yielding coupling
What original access lock was used to the connection of interior door drive mechanism by gate cabin intermediate solid drive shaft is rigid coupling, because the penetration piece place needs sealing, small misalign or angular deviation will cause and produces very big frrction load between sealing axle sleeve and the power transmission shaft between the diaxon, thus the operability of gate influenced.The present invention has selected the helical spring shaft coupling for use.Because use helical spring flexible joint, its allowable variation is good, allowing maximum parallel deviation is 3% of maximum axle journal, and maximum permission angular deviation is 3 °, and this will reduce the frrction load that axle seals out greatly, thereby reduce the operation moment of torsion of door.
5. increase universal coupling
The power transmission shaft of original access lock from interior gate interlock and main drive gear to inside door only designed a universal coupling, need pull down a lot of component of interlocking and main drive gear when changing axle envelope sealing ring like this, and the installation of component needs accurate the adjustment, and spended time is very long.The present invention has respectively increased a universal coupling at these two positions, and making the distance of two universal joints guarantee to run through axle can withdraw from from sealing axle sleeve, the easy maintenance of gate.
6. modification shaft seal structure
Whole access lock has everywhere, and axle seals as pressure-bearing boundary.Original shaft seal structure sealing ring is arranged on the axle, and sealing ring rotates with axle, and axle is bigger with the gap of sealing axle sleeve, and sealing ring might be squeezed in axle and the gap of overlapping and be rubbed and do not reach required seal request.The present invention has revised axle envelope, and amended sealing ring does not rotate with axle and the gap of axle and cover dwindles, and makes sealing ring be squeezed bad may diminishing greatly, has reduced fault rate, and sealing ring is with spool more stable with contacting of overlapping simultaneously, and airtight quality also is improved.
7. the improvement in pressure measxurement loop
The pressure measxurement loop of original access lock is made up of quick connector and flexible pipe, and the life-span is very short, needs often to change.The present invention adopts the nuclear grade stainless steel pipe and has the fast street corner of inserting of nuclear level authentication, has prolonged the application life of consumable accessory under the condition that guarantees the gate sealing, and has selected the valve of nuclear secondary, has fundamentally guaranteed the sealing of containment.
Access lock (seeing Fig. 1,2) mainly by interior shell ring 1, outer shell ring 2, run through shell ring 3, interlocking mechanism 4, pressure balance mechanism 5, hermatic door 6, retaining mechanism 7, linkage 8, lifting body 9, lifting doorsteps 10, parts such as transmission mechanism are formed, and concrete structure is seen Fig. 1 and Fig. 2.Inside and outside shell ring be installed in respectively containment vessel inside and outside, by welding mutually, form a closed in space with the shell ring that runs through that runs through, is anchored on the containment.The required transmission mechanism of opening and closing gate, linkage, retaining mechanism and relevant auxiliary body are housed in the gate.Mainly comprise following parts:
1. interlocking mechanism's (as shown in Figure 1)
Inside and outside hermatic door normal operating conditions is all in the closed position.When containment was in isolation, functions of the equipments required not allow to open simultaneously two doors, to guarantee the sealing of containment.The setting of interlocking mechanism is exactly to utilize mechanical means to reach this purpose.When wherein Yishanmen is opened, lock plunger is extracted out from lock bracket on the locking device, slide bar on the sliding rod rack loses restriction, so slide bar moves in sliding rod rack under the effect of spring restoring force, the promotion ratchet blocks ratchet to be made it and can not rotate, the drive link that ratchet links to each other passes doorframe (the external door ratchet is in the cabin) and pins the sprocket wheel synchronous with axle, this sprocket wheel pins the final drive shaft of other Yishanmen again, make the auto-manual of other Yishanmen all be under the restriction and can't operate, thereby reach the purpose of interlocking.If opened door is shut, lock plunger pushes up back slide bar, and slide bar promotes ratchet disengagement ratchet in the process of pushing up back, and ratchet can freely be rotated, and ratchet is driven in the power transmission shaft of other Yishanmen, has just removed interlocking, and Yishanmen just can be opened in addition.When two fan doors need be opened simultaneously, manually throw off the interlocking clutch and remove interlocking.Can operate by auto-manual, make two fan doors be in the optional position.
Pressure balance mechanism (as shown in Figure 6)
A flap type is all arranged on each doorframe, and two valves are consistent with the seal request of hermatic door under the reactor operation operating mode, for guaranteeing the sealing of containment, can not open them simultaneously, therefore this valve folding linked to each other with transmission mechanism.When door is opened, transmission mechanism is at first opened this valve, the pressure of pressure and the external space of opening the door in the access lock cabin is balanced each other, reduce the lateral force that produces because of pressure reduction, be convenient to the unlatching of door and prevent because pressure reduction damages the personnel's health that passes in and out to door-plate.
Retaining mechanism (as shown in Figure 7)
Retaining mechanism is mainly by the crank connecting link that is contained on the door, and leading screw, steering gear and the mechanisms such as lock bracket that are contained on the doorframe form.Four lock brackets that respectively are being symmetrically distributed about upper and lower turn-screw, the double output shaft output torque of steering gear is by upper and lower two cover chain wheel drive leading screws rotations, by the translation of crank-link mechanism drive lock plunger.Realize the locking of door.When the leading screw backward rotation, the nut on the leading screw moves to the middle part of door respectively up and down, and lock plunger is extracted lock bracket, unlocking.
Linkage (as shown in Figure 8)
Hermatic door is the axle center reaches door towards the inside and outside rotation of cylindrical shell opening and closing with the hinge axis.Inside door can be opened to 180 °, and external door is influenced by cylindrical shell in the cabin and reaches 100 ° only.Up and down two groups of hinges are arranged on the hinge axis, and bolt is fixed on door on the hinge bracket, the total weight of door by hinge effect in hinge axis.Self-aligning roller bearing is equipped with at the hinge axis two ends, and upper bearing (metal) bears the part radial load, and lower bearing bears axial load and part radial load.The last lower shaft end of hinge axis is fixed on the doorframe by board-like П type support.With hinge axis is coaxial one group of sprocket wheel is installed, gives lifting body the transmission of power of steering gear output, retaining mechanism, realize door jacking, unlatching and decline, close.
Lifting body (as shown in Figure 9)
Lifting body is fixed on the jacking support that welds mutually with hinge axis, and mechanism is by jacking driving support seat, transmission case, formations such as screw pair.Chain drives leading screw through steering gear, orders about transmission case and seesaws.Upper roller pushes against block when transmission case advances, and the horizontal sextant angle of support arm and leading screw adds senior general's door jack-up, and the horizontal sextant angle of support arm dwindled when transmission case retreated, and door is put down.The lifting distance of door is 60mm, and concrete structure is seen figure.
Lifting doorsteps (as shown in figure 10)
Access lock cabin base plate is the intermediate axle in attachment security shell inner platform and verandah aisle.For the ease of passing through of travelling bogie, three floors should be on the same horizontal plane, require the doorframe base (threshold) should be concordant with the cabin base plate.Because the position of doorframe sealing surface is lower than the cabin base plate, when the hermatic door lifting was opened, door shared space when fastening had just formed groove, and the effect of doorsteps is exactly to fill up this space, guarantees that passage is unblocked.Door drops on the doorsteps when closing, and doorsteps are descended.Hermatic door promotes two stage clips under the back release elevating stage, elevating stage rising packing space, unified plane.The stop nut of distance below the regulating spring mandrel that doorsteps rise realized.Falling what be in direct contact with it on the doorsteps when hermatic door is the roller at doorsteps two ends, and the setting of roller is in order to reduce door lock when tight and the friction of elevating stage.Concrete structure is seen figure.
Transmission mechanism
The driving of door has automatic and manual dual mode, on the transmission mechanism two pairs often open, the realization of normally closed electromagnetic clutch is automatic-manually operated switching.
