Abstract
The utility model discloses a manual emergency device is transported to fuel. The steel wire rope of the manual emergency device is transported through fuel and is connected with the tail plate of the transport trolley, and the steel wire rope moves along with the transport trolley. The device comprises a lower fixed pulley arranged on one side of the trolley, an upper fixed pulley is arranged above the lower fixed pulley, a manual winch is arranged on one side of the upper fixed pulley, a movable pulley is arranged below the upper fixed pulley and the manual winch, and a balance weight is arranged on the movable pulley. The trolley, the lower fixed pulley, the upper fixed pulley, the movable pulley and the manual winch are sequentially connected through a steel wire rope. Through the manual emergency device, when the fuel transfer device normally operates, the problems of movement and placement of the steel wire rope are solved; when the transport trolley breaks down, the trolley can be pulled back to a specified position through the device.
Description
Technical field
The utility model relates to fuel for nuclear power plant transhipment field, is specifically related to a kind of fuel transhipment manual-operated emergent device.
Background technology
In the fuel transport process of nuclear power station, the manual-operated emergent device is dolly while breaking down, device emergency requirement, that can manually drag dolly, and the emergency wire rope need to be followed moving of car.In dolly transhipment scheme, in existing emergency set, dolly, fixed pulley are connected by wire rope successively with windlass, and in the motionless situation of windlass, the rope capacity needed during operation changes at any time, can't solve the placement of wire rope and drag problem.
The utility model content
For the defect existed in prior art, the purpose of this utility model is to provide a kind of fuel transhipment manual-operated emergent device, solves motion and the Placement Problems of wire rope.When carriage fault occurs, make dolly be back to assigned address.In addition, by detecting the position of counterweight, immediately detect the positional information of dolly.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of fuel transhipment manual-operated emergent device, comprise the dolly be arranged on fuel transfer tube, one side of dolly is provided with the bottom fixed pulley, the stand of fixed pulley top, bottom is provided with the top fixed pulley, one side of top fixed pulley is provided with manual hoist, the below of top fixed pulley and manual hoist is provided with travelling block, and travelling block is provided with counterweight, and dolly, bottom fixed pulley, top fixed pulley, travelling block are connected by wire rope successively with manual hoist.
Further, a kind of fuel transhipment manual-operated emergent device as above, also be provided with on described stand for surveying the scrambler of balance position.
Further, a kind of fuel transhipment manual-operated emergent device as above, described manual hoist comprises reel, turbine and worm and handle.
The beneficial effects of the utility model are: manual-operated emergent device provided by the utility model, when fuel transfer device normally moves, solved motion and the Placement Problems of wire rope, when travelling bogie breaks down, by this device, dolly can be withdrawn into to assigned address.In addition, can also in the situation that can't survey easily little truck position, obtain the position of dolly by the position of measuring counterweight by this device.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of fuel transhipment manual-operated emergent device in the utility model embodiment.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is described in further detail.
Fig. 1 shows the structural representation of a kind of fuel transhipment manual-operated emergent device in the utility model embodiment, this manual-operated emergent device comprises that the dolly 1 be arranged on fuel transfer tube, a side of dolly 1 are provided with bottom fixed pulley 2, the stand of bottom fixed pulley 2 tops is provided with top fixed pulley 3, one side of top fixed pulley 3 is provided with manual hoist 5, the below of top fixed pulley 3 and manual hoist 5 is provided with travelling block 4, and travelling block 4 is provided with counterweight 7.Dolly 1, bottom fixed pulley 2, top fixed pulley 3, travelling block 4 and manual hoist 5 are connected successively by wire rope 6, and the wire rope of transporting the manual-operated emergent device by this fuel is connected with the tailgate of travelling bogie, and wire rope moves with travelling bogie.In addition, on the stand of this device, also be provided with for surveying the scrambler of counterweight 7 positions.
Manual hoist 5 comprises reel, turbine and worm and handle etc.When fuel transfer device normally moves, manual hoist 5 self-lockings, travelling block 4(is containing counterweight 7) can be with dolly 1 motion.When dolly 1 advances, travelling block 4 rises with counterweight 7, and when dolly 1 retreats, counterweight 7 descends thereupon, and counterweight 7 strokes are half of dolly 1.When implementing to arrange manual-operated emergent device of the present utility model, top fixed pulley 3 is arranged on the support of dolly 1 and bottom fixed pulley 2 tops with manual hoist 5.
When dolly breaks down, can shake manual hoist 5, travelling block 4 and counterweight 7 are shaken to assigned address and fixed, make travelling block 4 change fixed pulley into, then be rotated further manual hoist 5, by wire rope 6 tractions, dolly 1 is retracted to the position of appointment.Simultaneously, by manual-operated emergent device of the present utility model, when operation, because the stroke of counterweight is half of dolly stroke, in the situation that can't survey easily little truck position, can survey the position that obtains counterweight 7 by scrambler, thereby obtain the position of dolly 1.
Of the present utility model focusing on counterweight 7(containing travelling block 4) be incorporated into transporter, during normal operation, counterweight 7 can and can be judged little truck position by it with dolly 1 motion, when fault, counterweight 7(is containing fixed pulley 4) can be fixed again, realize by manual the little assigned address that retracts.
Obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technology thereof, the utility model also is intended to comprise these changes and modification interior.
