Hoisting mechanism main body generally prismatoid, the hole for hoist on top as described above opens up in the horizontal direction, lower part Guide groove opens up from bottom to top in lower end surface;Locking pin connecting hole is opened up in the horizontal direction in the arranged on left and right sides of guide groove, is used for Across check lock lever.
The generally hollow cuboid of cylinder block as described above, left end are fixed on hoisting mechanism main body locking pin connection The right end in hole, for fixing cylinder.
Cylinder as described above is fixed on cylinder block right end, and cylinder rod protrudes into the inside of cylinder block, for driving check lock lever Movement.
Check lock lever generally cylindrical as described above, right end are fixed on cylinder rod, left under the drive of cylinder rod, Right movement.
Side guide plate as described above is rectangle tabular, altogether there are two, before hoisting mechanism main body guide groove is set, Two sides afterwards, for playing the guiding role to pressure vessel check device lifting part and being lifted to check lock lever and pressure vessel check device Part is protected.
Check lock lever, hoisting mechanism main body, cylinder block, cylinder and side guide plate as described above are all made of stainless steel material It is made.
The beneficial effects of the utility model are:
Using 1 structure feature of lifting part, by hoisting mechanism main body 4 be processed into lifting part 1 can fit structure, in hoisting machine 4 two sides of structure main body are equipped with side guide plate 7.Cooperated by the two, realizes that crane and the remote of pressure vessel check device are determined Position.It is remotely located quick and precisely, provides safety guarantee for subsequent locking connection.
The long-range connection of hoisting mechanism 20 and pressure vessel check device is realized by remotely controlling cylinder 6.It is easy to operate, Securely and reliably, reduce working time of the operator under radiation environment, improve lifting efficiency.
Detailed description of the invention
Fig. 1 is the three-dimensional structure diagram of the utility model;
Fig. 2 is the front sectional view of the utility model;
Fig. 3 is the right view of the utility model;
Fig. 4 is the right side view of the utility model;
Wherein: 1. pressure vessel check device lifting parts, 2. check device hoisting mechanisms, 3. check lock levers, 4. hoisting mechanisms Main body, 5. cylinder connection pieces, 6. cylinders, 7. side guide plates.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples.
As shown in Figures 1 to 4, a kind of nuclear reactor pressure container check device hoisting mechanism, including check lock lever 3, lifting Mechanism body 4, cylinder block 5, cylinder 6 and side guide plate 7.The shape and structure of hoisting mechanism main body 4 are examined according to pressure vessel The decision of 1 structure feature of device lifting part is looked into, the hole for hoist connecting with suspension hook is machined on 4 top of hoisting mechanism main body, is lifting 4 lower part of mechanism body processes the guide groove matched with pressure vessel check device lifting part 1, and one is machined at guide groove Locking pin connecting hole.Cylinder 6 is connect by cylinder block 5 with hoisting mechanism main body 4, installation locking bar 3 on cylinder rod, in hoisting machine 4 lower section guide groove two sides of structure main body are equipped with two pieces of side guide plates 7.
The generally prismatoid of hoisting mechanism main body 4, the hole for hoist on top open up in the horizontal direction, the guiding of lower part Slot opens up from bottom to top in lower end surface.Open up locking pin connecting hole in the horizontal direction in the arranged on left and right sides of guide groove, for across Check lock lever 3.
The generally hollow cuboid of the cylinder block 5, left end are fixed on 4 locking pin connecting hole of hoisting mechanism main body Right end, for fixing cylinder 6.
The cylinder 6 is fixed on 5 right end of cylinder block, and cylinder rod protrudes into the inside of cylinder block 5, for driving check lock lever 3 Movement.
The generally cylindrical of check lock lever 3, right end is fixed on cylinder rod, left and right under the drive of cylinder rod Movement.
The side guide plate 7 be rectangle tabular, altogether there are two, the forward and backward of 4 guide groove of hoisting mechanism main body is set Two sides, for playing the guiding role to pressure vessel check device lifting part 1 and being lifted to check lock lever 3 and pressure vessel check device Part 1 is protected.
