Referring to fig. 1 to 3, fig. 1 illustrates a structure of a hoisting device and a transformer core in an embodiment of the present invention, and fig. 2 and 3 illustrate a structure of a hoisting device in an embodiment of the present invention;
the embodiment provides a hoisting device 200, where the hoisting device 200 includes a first hoisting platform 210, a fine adjustment mechanism 220, and a second hoisting platform 230;
the first hoisting platform 210 is used for connecting with the hoisting tool 10, and the second hoisting platform 230 is used for connecting with the transformer core 20; the first hoisting platform 210 is parallel to the second hoisting platform 230, the fine adjustment mechanism 220 is positioned between the first hoisting platform 210 and the second hoisting platform 230, and the fine adjustment mechanism 220 is movably connected with the first hoisting platform 210 and the second hoisting platform 230;
the fine adjustment mechanism 220 is configured to drive the second hoisting platform 230 to move along a first direction (as indicated by arrow a in fig. 2) and a second direction relative to the first hoisting platform 210; the first direction and the second direction are both located on the horizontal direction and are perpendicular to each other.
It should be noted that, in this embodiment, when the first hoisting platform 210 is connected to the hoisting tool 10 and the second hoisting platform 230 is connected to the transformer core 20, both the first hoisting platform 210 and the second hoisting platform 230 may be horizontal, and the motions in the first direction and the second direction both refer to displacements in the horizontal direction, that is, when the fine adjustment mechanism 220 drives the second hoisting platform 230 to move in the first direction and the second direction relative to the first hoisting platform 210, both the motions of the second hoisting platform 230 are motions in the horizontal direction, so that the position adjustment amount of the second hoisting platform 230 in the hoisting process is reduced in this way.
The working principle of the hoisting device 200 is as follows:
referring to fig. 1 to 3, the hoisting device 200 includes a first hoisting platform 210, a fine adjustment mechanism 220 and a second hoisting platform 230; the first hoisting platform 210 is used for being connected with the hoisting tool 10, and the second hoisting platform 230 is used for being connected with the transformer core 20; the first hoisting platform 210 is parallel to the second hoisting platform 230, the fine adjustment mechanism 220 is positioned between the first hoisting platform 210 and the second hoisting platform 230, and the fine adjustment mechanism 220 is movably connected with the first hoisting platform 210 and the second hoisting platform 230; the fine adjustment mechanism 220 is configured to drive the second hoisting platform 230 to move along a first direction and a second direction relative to the first hoisting platform 210; the first direction is perpendicular to the second direction. Therefore, during the hoisting process, since the first hoisting platform 210 is used for connecting with the hoisting tool 10 and the second hoisting platform 230 is used for connecting with the transformer core 20, the hoisting tool 10 can hoist the transformer core 20 through the hoisting device 200, and the first and second lifting platforms 210 and 230 are parallel to the horizontal plane during the lifting process, further, the fine adjustment mechanism 220 can drive the second lifting platform 230 to move along the first direction and the second direction relative to the first lifting platform 210, so as to adjust the position of the transformer core 20 connected with the second lifting platform 230, thereby adjusting the gap between the lifted transformer core 20 and the transformer housing, further, the transformer core 20 and the transformer oil tank shell are prevented from colliding in the hoisting process of the transformer core 20, so that accidents in the hoisting process of the transformer core 20 are avoided.
It should be noted that, in this embodiment, in the process of hoisting by the hoisting device 200, the fine adjustment mechanism 220 may drive the second hoisting platform 230 to move along one of the first direction and the second direction, or drive the second hoisting platform 230 to move synchronously along the first direction and the second direction, and the specific moving direction may be determined according to the gap between the transformer core 20 and the transformer housing in the actual hoisting process.
Further, referring to fig. 1-3, in the present embodiment, the fine adjustment mechanism 220 includes a movable block 221, a first movable member 222, and a second movable member 223; wherein, the first movable member 222 is movably connected with the first hoisting platform 210, and the movable block 221 is in transmission connection with the first movable member 222; the first movable piece 222 is used for moving relative to the first hoisting platform 210 under the action of an external force and driving the movable block 221 and the second hoisting platform 230 to move along a first direction; the second movable member 223 is movably connected with the movable block 221, and the second hoisting platform 230 is in transmission connection with the second movable member 223; the second movable member 223 is configured to move relative to the movable block 221 under the action of an external force, and drive the second lifting platform 230 to move along the first direction.
Therefore, by such an arrangement, the second lifting platform 230 can be driven to move along the first direction by controlling the movement of the first movable element 222 relative to the first lifting platform 210; similarly, by controlling the movement of the second movable member 223 relative to the movable block 221, the second hoisting platform 230 can be driven to move along the second direction; in addition, due to the arrangement mode, the movement of the movable block 221 relative to the first hoisting platform 210 and the movement of the second hoisting platform 230 relative to the movable block 221 are relatively independent, so that when the second hoisting platform 230 moves along the first direction and the second direction, the movements in the two directions do not interfere with each other, and the precision of displacement and the efficiency of displacement can be improved.
Further, referring to fig. 1 to fig. 3, in the present embodiment, when the first movable member 222 and the second movable member 223 are disposed, the first movable member 222 is rotatably connected to the first hoisting platform 210, and the movable block 221 is in threaded engagement with the first movable member 222; the second movable member 223 is rotatably connected to the movable block 221, and the second hoisting platform 230 is in threaded engagement with the second movable member 223. That is, the first movable member 222 and the second movable member 223 may be lead screws.
And the movable block 221 is slidably engaged with the first lifting platform 210 along the first direction, and the second lifting platform 230 is slidably engaged with the movable block 221 along the second direction.
It should be noted that, the hoisting device 200 is used to adjust the gap between the transformer core 20 and the transformer housing during the hoisting of the transformer core 20, so that the position is finely adjusted during the position adjustment process, and the adjustment amount is small, thereby the purpose of such an arrangement is to improve the adjustment accuracy of the displacement by means of screw transmission.
Further, referring to fig. 1-3, in the present embodiment, when the first hoisting platform 210 and the movable block 221 are disposed, since the movable block 221 is slidably engaged with the first hoisting platform 210 and the second hoisting platform 230 is slidably engaged with the movable block 221, a first sliding slot 224 is disposed along the second direction on a surface of the first hoisting platform 210 facing the second hoisting platform 230, and the movable block 221 is accommodated in the first sliding slot 224; the first movable member 222 crosses the first sliding slot 224 and is in threaded engagement with the movable block 221 accommodated in the first sliding slot 224; a second sliding groove is formed in the surface of the movable block 221 departing from the first hoisting platform 210 along the first direction, and the second hoisting platform 230 is accommodated in the second sliding groove; the second movable member 223 crosses the second sliding slot and is in threaded engagement with the second hoisting platform 230 accommodated in the second sliding slot.

It should be noted that, when the first sliding slot 224 and the second sliding slot are provided, since the first sliding slot 224 is opened along the second direction and the second sliding slot is opened along the first direction, the movement of the movable block 221 in the first sliding slot 224 is from one side of the first sliding slot 224 to the other side; similarly, the second lifting platform 230 moves in the second sliding groove from one side of the second sliding groove to the other side.
It should be noted that, when the first sliding slot 224, the movable block 221 and the second hoisting platform 230 are arranged, since the first sliding slot 224 is formed in the second direction on the surface of the first hoisting platform 210 facing the second hoisting platform 230, the movable block 221 is accommodated in the first sliding slot 224; a second sliding groove is formed in the surface of the movable block 221 departing from the first hoisting platform 210 along the first direction, and the second hoisting platform 230 is accommodated in the second sliding groove; therefore, at least a portion of the movable block 221 is received in the first sliding slot 224, and at least a portion of the second lifting platform 230 is received in the second sliding slot.
Further, referring to fig. 1 to 3, in order to limit the movement of the movable block 221 along the first direction and the movement of the second hoisting platform 230 along the second direction, the movable block 221 can be in surface contact with the bottom surface of the first sliding groove 224, and the second hoisting platform 230 can be in surface contact with the bottom surface of the second sliding groove, so that when the first movable member 222 and the second movable member 223 are both screw rods, the movement of the movable block 221 relative to the first hoisting platform 210 and the second hoisting platform 230 relative to the movable block 221 is guided by a surface contact manner.
Further, referring to fig. 1 to fig. 3, in this embodiment, in order to improve the hoisting stability, when the fine adjustment mechanism 220 drives the transformer core 20 to move along the first direction and the second direction, the hoisting device 200 and the transformer core 20 are prevented from swinging, so that a first hoisting portion 225 is disposed on a surface of the first hoisting platform 210 departing from the fine adjustment mechanism 220, and the first hoisting portion 225 is used for being connected to the hoisting device 10; a second hoisting part 226 is arranged on the surface of the second hoisting platform 230 departing from the fine adjustment mechanism 220, and the second hoisting part 226 is used for hoisting the transformer core 20; and, the first and second hoisting parts 225 and 226 each include a plurality of hoisting rings 227 arranged at uniform intervals.
