Referring to fig. 1 to 5, the present invention provides a technical solution: the utility model provides a wind turbine generator system base hoisting structure, includes calibration mechanism and lower calibration mechanism, still including being used for installing the installation mechanism on the wind turbine generator system base with last calibration mechanism and lower calibration mechanism, go up calibration mechanism including installing the flange 19 on installation mechanism, lower calibration mechanism includes oil collar 01 of fixed connection on installation mechanism, installs oil tank 03 on the oil collar 01, installs buffer board 04 on the oil tank 03.
Most of the existing wind turbine generators are hoisted by a crane, but when the wind turbine generators are hoisted, the wind turbine generators are suspended by a hoisting rope of the crane and are not fixedly connected, so that the wind turbine generators can shake due to the deviation of the gravity center when moving, the butt joint between the wind turbine generator bases is inconvenient, and particularly when the wind turbine generators are in high altitude, the hanging wind turbine generator bases shake due to the action of air flow, so that the construction difficulty is increased;
the technology is characterized in that an upper calibration mechanism and a lower calibration mechanism are respectively arranged on two wind turbine bases to be butted through an installation mechanism, when a crane hangs an upper base above an installed wind turbine base, the upper base is controlled by the crane to approach the two bases, but the upper base and the lower base cannot be observed to be butted at a high altitude because a control working chamber of the crane is generally arranged on the ground, when the crane approaches the two bases, the correction wedge 13 gradually moves towards the buffer plate 04 at the moment, when the suspended base and the installed base are different in axis, the correction wedge 13 towards the offset side is positioned above the buffer plate 04 at the moment, when the correction wedge 13 moves downwards, the buffer plate 04 props against the correction wedge 13, and an inclined plane is arranged on the correction wedge 13, the correction wedge blocks 13 are arranged, so that the buffer plate 04 can enable the correction wedge blocks 13 to move towards the side far away from the buffer plate 04 by pushing the inclined surfaces of the correction wedge blocks 13, thereby achieving the function of correction, and because the correction wedge blocks 13 are arranged in a plurality of ways, no matter which side the suspended base is deviated, the function of automatic centering can be achieved, thereby ensuring that the suspended base is coaxial with an installed base, so that the installed wind turbine base can support the base suspended by the crane, thereby achieving the installation, and because the wind turbine base is heavier, a larger force is required to achieve the function of pushing the correction, the correction wedge blocks 13 are pushed by pushing the self weight of the wind turbine base through the buffer plate 04 when the crane releases the wind turbine base downwards, thereby achieving the correction, and no power mechanism is required, the correction function is automatically realized, so that the problem that power equipment is inconvenient to use in high altitude is also solved.
As a further scheme of the invention, the installation mechanism consists of a plurality of groups of supporting structures and also comprises a locking structure arranged between the two groups of supporting structures, the supporting structure comprises a supporting plate 02, a supporting foot 18 for supporting is fixedly connected to one side surface, far away from a convex plate 19, of the supporting plate 02, the locking structure comprises a winding box 12, the supporting foot 18 for supporting is arranged on the winding box 12, a rope drum 15 is rotationally connected to the winding box 12, a steel cable 16 fixedly connected with the supporting plate 02 is fixedly connected to the rope drum 15, a crank 17 for rotating is arranged on the rope drum 15, a locking wheel 14 is fixedly connected to the rope drum 15, a locking clamping block 26 is fixedly connected to the winding box 12, a clamping jaw 25 for limiting the locking wheel 14 is fixedly connected to the clamping jaw 25, a correction wedge 13 of the upper calibration mechanism is fixedly connected to the supporting plate 02, and an oil ring 01 of the lower calibration mechanism is fixedly connected with the supporting plate 02.
The steel cable 16 and the supporting plate 02 can be hung in a hook mode, so that one steel cable 16 and the supporting plate 02 can be hung for installation, the whole installation mechanism can be taken down only by disassembling one steel cable 16 when the wind turbine generator is disassembled, the disassembly is convenient, the whole installation mechanism is looped on the outer wall of the wind turbine generator base when the wind turbine generator is installed, after the steel cable 16 is hung, the crank 17 is rotated, the rope drum 15 is driven to rotate, the steel cables 16 on two sides are wound on the rope drum 15, then the steel cables are stretched into the locking wheel 14 through the clamping claw 25 to be clamped with the locking wheel 14, and the brake block 27 is clamped in the locking clamping block 26, so that the rope drum 15 is clamped through the clamping locking wheel 14, and the rope drum 15 cannot rotate; when the wind turbine generator is installed, the installation position angles of the installation mechanism on the hoisted wind turbine generator base and the installation mechanism on the installed wind turbine generator base are required to be consistent, so that the subsequent correction wedge 13 can be supported by the buffer plate 04.
As a further scheme of the invention, the lower calibrating mechanism further comprises a buffer mechanism, the buffer mechanism comprises a second piston plate 23 which is connected in the oil tank 03 in a sliding way, a second sliding rod 08 is fixedly connected to the second piston plate 23, the upper end of the second sliding rod 08 extends out of the oil tank 03 and is fixedly connected with the buffer plate 04, a flow limiting pipe 20 which is communicated with the oil ring 01 is communicated with the oil tank 03, the lower end of the oil tank 03 is fixedly connected with a first sliding rod 05 which penetrates through the oil ring 01, a first piston plate 22 which is fixedly connected with the first sliding rod 05 is connected in a sliding way in the oil ring 01, a spring which can enable the buffer plate 04 to reset is fixedly connected to the oil tank 03, and a spring which can enable the oil tank 03 to reset is arranged on the outer wall of the first sliding rod 05.
Because the dead weight of the wind turbine generator bases is large, when the wind turbine generator bases just start to contact, the two wind turbine generator bases are easy to directly collide by releasing the crane, so that the two wind turbine generator bases are damaged;
when the hydraulic oil buffer device is used, when the crane downwards releases the wind turbine generator base, firstly, the correction wedge 13 pushes the buffer plate 04 to enable the buffer plate 04 to push the piston plate II 23 to move downwards on the oil tank 03 through the sliding rod II 08, so that hydraulic oil in the piston plate II 23 can flow into the oil ring 01 through the flow limiting pipe 20, hydraulic oil in the oil tank 03 cannot quickly flow through the flow limiting pipe 20 in a short time due to the smaller caliber of the flow limiting pipe 20, the wind turbine generator base can be decelerated and buffered through the descending of the deceleration buffer plate 04, and the buffer plate 04 is provided with a plurality of buffer plates, so that the buffer can be realized no matter the correction wedge 13 leans towards the side, and the buffering process is realized through the movement of the buffer plate 04, so that the functions of protecting an upper calibration mechanism and a lower calibration mechanism can be also realized, and the device damage caused by direct contact of the wind turbine generator base can be prevented.
As a further scheme of the invention, the lower calibration mechanism further comprises a centering mechanism, the centering mechanism consists of two groups of symmetrical boosting mechanisms, the boosting mechanism comprises an oil pipe 11 communicated with the oil ring 01, the upper end of the oil pipe 11 is communicated with the two ends of a buffer plate 04, the upper end of the oil pipe 11 is arc-shaped, the upper end of the oil pipe 11 is slidably connected with a piston push rod 24, a boosting block 09 fixedly connected with the piston push rod 24 is slidably connected with the buffer plate 04, a limiting block 10 is fixedly connected in the buffer plate 04, the upper end of the oil pipe 11 is a hard pipe, and the lower end of the oil pipe 11 is a soft pipe.
The lower calibration mechanism can realize the butt joint between the two wind turbine bases in the horizontal plane direction, so that the two wind turbine bases are coaxially parallel, but when the lower calibration mechanism is used for mounting, screw holes on the wind turbine bases are not aligned;
after the buffer plate 04 moves completely onto the oil tank 03, the convex plate 19 is located on the buffer plate 04, the inclined surface of the correction wedge 13 is not in contact with the buffer plate 04, and cannot continuously descend relative to the oil tank 03, so that the oil tank 03 starts to descend and starts to push the piston plate I22 to descend through the slide rod I05, the piston plate I22 pushes hydraulic oil in the oil ring 01 into the oil inlet pipe 11, so that the piston push rod 24 slides in the oil pipe 11, the piston push rod 24 pushes the boosting block 09 to move towards the side close to the limiting block 10, the position of the convex plate 19 on the correction wedge 13 is pushed through the two boosting blocks 09, the correction wedge 13 is centered to the position of the limiting block 10, and the correction wedge 13 pushes the supporting plate 02 to enable rotation calibration of the hung wind turbine base, and bolt holes of the hung wind turbine base and the installed wind turbine base are aligned.

Because the two wind turbine generator bases can be butted with the bolt holes only after the two wind turbine generator bases are coaxially parallel, the correction of the bolt holes cannot be performed when the two wind turbine generator bases are not coaxially corrected;
therefore, when two wind turbine generator bases are in butt joint, firstly, the correction wedge 13 and the buffer plate 04 are in direct contact at one side of the inclination, so that the buffer function is firstly carried out until the buffer is finished, the correction is started, because the length of the convex plate 19 is long enough, when the correction wedge 13 descends along with the correction function, the buffer plate 04 is pushed by the other convex plates 19 to descend relative to the oil tank 03, but the buffer effect is not carried out, when the correction is finished, all the buffer plates 04 descend to be propped against by the oil tank 03, at the moment, the descending of the buffer plates 04 can push hydraulic oil in the oil tank 03 into the oil ring 01 through the piston plate two 23, and the capacity of the hydraulic oil in the oil ring 01 and the capacity of the oil box 06 are equal to the capacity of the oil tank 03, so that the hydraulic oil in the oil tank 03 is only completely fed into the oil ring 01 when the oil ring 01 is fully loaded, the limiting rod 07 is gradually pushed to slide outwards on the oil box 06, the limiting rod 07 is separated from the oil box 06 and the sliding rod 05, and only when the oil ring 01 is in the oil ring 01 is fully loaded, the wind turbine generator bases are in butt joint, and the butt joint can be completed.
