Description

Useless filter core is changed transfer container load measurement and overload protection device
Technical field
The utility model relates to the overload protection field that nuclear power plant and the useless filter core replacing transhipment of nuclear chemical industry radioactivation and similar weight promote, and more particularly, the utility model relates to a kind of useless filter core and changes transfer container load measurement and overload protection device.
Background technology
In systems such as boron recovery system, Liquid Radwaste Treatment, reactor and the cooling of spentnuclear fuel pond and disposal system, chemical volume control system, steam generator blowdown system; Usually utilizing useless filter core to change transfer container (being called for short " transfer container ") changes and falls with transport resistance or the useless filter core of radioactivation that radioactive dosage exceeds standard; Detailed process is: through special tool the cartridge chamber opening; Pick up the useless filter core of taking-up with the automatic grasper of transfer container; And be promoted to transfer container inside; Use again and drive a vehicle the transfer container handling to useless filter core decline passway, thereby following the useless filter core of shielding protection that is implemented in transfer container is transported on the useless filter core decline passway from the replacing of cartridge chamber; Then, the gripping apparatus of transfer container descends, and is sent to useless filter core in the container of its below barreling station through useless filter core decline passway, afterwards it is cured processing.
Change in the transport process at above-mentioned useless filter core; Transfer container is sometimes because different former thereby transship, as: the loam cake etc. that pushes up transfer container when clamping stagnation, useless filter core arrival transfer container top appear in useless filter core when the cartridge chamber begins to lift by crane because of position stroke switch failure.Overload protection for transfer container; Generally be to measure its load (making a concerted effort of gravity, automatic grasper gravity and the resistance of useless filter core) at present with weight sensor; And deliver to PLC (Programmable Logic Controller to result of a measurement; Programmable logic controller (PLC)) judges identification, carry out actions such as motor outage stall again according to judged result, thereby transfer container parts such as reducing motor are protected.
See also shown in Figure 1ly, existing useless filter core changes the transfer container load measurement and overload protection device is to utilize the cooperation of steel rope 10 and pulley 12,13 to promote or the useless filter core that descends.One end of steel rope 10 is fixed on the reel of reducing motor, and two pulleys 12,13 are walked around at the middle part, and the other end is provided for grasping the automatic grasper of useless filter core.The base of two pulleys 12,13 is separately fixed on the bearing plate 14, and a side of bearing plate 14 can rotate and transport hinge 16 rotations on the container cover plate, and opposite side then is pressed on the weight sensor 18.When filter core is given up in lifting or decline; The actual load of steel rope 10 is delivered on the bearing plate 14 through pulley 12,13; And then be delivered on the weight sensor 18 according to lever principle, weight sensor 18 converts force signal electric signal into and sends it to PLC, and PLC measures the electric signal that receives and judges; And then actual load measured and judge; If overload then control the reducing motor stall makes steel rope 10 and automatic grasper stop to rise, thereby parts such as protection reducing motor and automatic grasper exempt from overload destruction.
But; Can find out from above description; It is comparatively complicated that existing useless filter core is changed the loading transfer path of transfer container load measurement and overload protection device; Force value that weight sensor 18 receives and actual load value are also unequal, and there is the conversion relation of an approximately linear in the two, and the feasible numerical value of weighing of this conversion relation becomes inaccurate.In addition; In the prior art scheme, the force structure of bearing plate 14 is a lever construction, and this structure has amplification to vertical vibrations of pulley 12,13; The vibrations meeting of this amplification forms additional impact to weight sensor 18, causes the life-span of weight sensor 18 to be reduced greatly.
In view of this, the necessary accurate and long-lived useless filter core of a kind of load value measurement that provides is changed transfer container load measurement and overload protection device.
