Description

Technical Field

[0001] The utility model belongs to the technical field of assembled type bearing frames, and in particular relates to an assembled type bearing frame for assisting the maintenance of a wind turbine generator set. Background Art

[0002] The wind power source consists of a wind turbine generator set, a tower supporting the generator set, a battery charge controller, an inverter, an unloader, a grid-connected controller, a battery pack, etc. The wind turbine generator set includes a wind rotor and a generator; the wind rotor contains blades, a hub, reinforcements, etc. The wind turbine generator set may be damaged during use, and personnel are required to disassemble the damaged parts and place them in the carrier frame, and finally bring them back to the factory for repair.

[0003] For example, a Chinese patent with a publication number of CN218659033U discloses a maintenance tool carrier, comprising a main body, a universal wheel for movement is provided at the lower end of the main body, a placement platform is provided at the upper end of the main body for placing some larger tools that are inconvenient to hang and commonly used, a rectangular groove is provided in the main body, and evenly distributed slide grooves are provided in the groove, a drawer is provided at the rectangular groove of the main body, and evenly distributed slide grooves are provided at the foam pad, and an elastic component is provided in the slide groove, which is connected to the placement frame through the elastic component, so that the foam pad has a good elastic effect. When the tool is placed in the foam pad, the elasticity plays an elastic protection role on the tool, thereby reducing the rigid reaction force generated when the tool is placed, and playing an elastic protection role for the tool, and at the same time, a placement groove and a hook are provided at the outer end of the main body, and the placement groove and the hook are convenient for storing small or commonly used tools, so that it is easy to use.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when storing some parts that need to be repaired, it is inconvenient to take out the parts inside the carrier, and personnel need to reach in and take out the parts. At the same time, the above device is not convenient to assemble. When there are fewer parts to be stored, it cannot be freely assembled according to actual needs, and the structure or size cannot be changed, resulting in low space utilization of the carrier and increased manufacturing costs. In view of this, we propose an assembled carrier for auxiliary wind turbine maintenance. Utility Model Content

At this time, the two sliding bars are disengaged from the carrier three, and then the carrier three is taken out from above the top carrier two. At the same time, the cross protrusion under the rotating column in the carrier three will be disengaged from the cross groove of the rotating column in the top carrier two. Then, through the above operation, the four sliding bars on the lower carrier two are disengaged from the top carrier two, and then the top carrier two is taken out, and finally the carrier three is placed on the bottom carrier. A driving assembly is arranged above the carrier two. Under the action of the rebound force of several springs, the two springs on the lowest carrier two will slide in the corresponding sliding grooves and squeeze the corresponding two sliding bars to slide and move away from each other, so that the four sliding bars will all enter the carrier three, and the carrier three can be stuck. At the same time, the cross protrusion on the rotating column in the carrier three will enter the cross groove of the rotating column in the lowest carrier two, so that the personnel can turn the handle to drive the rotating column in the carrier three to rotate. The rotating column in the carrier three cooperates with the cross groove through the cross protrusion, so that the rotation of the rotating column in the carrier three can drive the rotation of the rotating column in the lowest carrier two.

[0020] In the technical solution, when the number of carriers needs to be reduced, first, the two extrusion blocks on the top carrier two are pushed downward, and at the same time, a number of springs on the top carrier two are squeezed and contracted. Under the tension of the four tension springs on the top carrier two, the two adjacent sliding bars on the top carrier two slide in the sliding groove and approach each other. At this time, the two sliding bars are disengaged from the carrier three, and then the carrier three is taken out from above the top carrier two. At the same time, the cross protrusion under the rotating column in the carrier three will be disengaged from the cross groove of the rotating column in the top carrier two.

At the same time, the cross protrusion under the rotating column 16 in the carrier frame 3 3 will be disengaged from the cross groove of the rotating column 16 in the top carrier frame 2 2. Then, through the above operation, the four sliding bars 6 on the lower carrier frame 2 2 are disengaged from the top carrier frame 2 2, and then the top carrier frame 2 2 is taken out, and finally Place the carrier three 3 above the bottom carrier two 2, then release the squeezing block 12, under the action of the rebound force of the springs 13, the two springs 13 on the bottom carrier two 2 will slide in the corresponding sliding grooves 5 and squeeze the corresponding two sliding bars 6 to slide and move away from each other, so that the four sliding bars 6 all enter the carrier three 3, and the carrier three 3 can be stuck. At the same time, the cross protrusion on the rotating column 16 in the carrier three 3 will enter the cross groove of the rotating column 16 in the bottom carrier two 2, so that the personnel can turn the handle 18 to drive the rotating column 16 in the carrier three 3 to rotate, and the rotating column 16 in the carrier three 3 cooperates with the cross groove through the cross protrusion, so that the rotation of the rotating column 16 in the carrier three 3 can drive the rotating column 16 in the bottom carrier two 2 to rotate.
