Description

Technical Field

[0001] This utility model relates to the technical field of cargo baskets for generator set non-climbing devices, specifically a cargo basket for wind turbine generator set non-climbing devices. Background Technology

[0002] When transporting items to the wind turbine nacelle, the non-climbing trolley has no safety protection measures. The trolley shakes and bumps slightly during operation, and items placed on the trolley's footboard are prone to falling and causing damage to the equipment and items. Although tool bags and hanging bags can serve a loading function, there are no safety protection measures during transportation, and the trolley's footboard needs to be retracted. If they are not properly suspended, they can easily fall and injure people or damage equipment. Therefore, using a cargo basket placed on the trolley's footboard can improve the safety of transporting goods.

[0003] Existing cargo baskets also lack fixing devices. If the trolley encounters shaking or bumps during the crawling process, the cargo basket may fall off. Moreover, the upper part of the cargo basket has an open structure, and goods or equipment can easily fall out of the cargo basket, causing damage to the goods and equipment. Therefore, this utility model provides a cargo basket for a wind turbine generator without crawling to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cargo basket for a wind turbine generator without a climbing device, so as to solve the problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cargo basket for a wind turbine generator without a crawler, comprising a crawling trolley and a placement box. The upper end of the crawling trolley is provided with a placement groove, and the placement box is placed in the placement groove. A box cover is hinged to the rear side of the top of the placement box via a built-in hinge. First connecting blocks are welded to both sides of the front face of the box cover. A second connecting block is welded to the placement box below the first connecting blocks. Bolts are threadedly connected to the first connecting blocks and the second connecting blocks.

[0006] Connecting seats A are welded to the middle of both sides of the crawling trolley, and connecting bolts A are threaded onto connecting seats A. Connecting seats B are welded to the upper side of the middle of both sides of the placement box, and connecting bolts B are threaded onto connecting seats B. A detachable connecting device is installed between connecting bolts A and connecting bolts B.

[0007] The connecting device includes a first hook that is hung on a connecting bolt A, and a lower screw is welded to the top of the first hook. A threaded cylinder with a threaded connection is fitted onto the upper end of the lower screw, and an upper screw is threadedly connected to the upper end of the threaded cylinder. A second hook welded to the upper end of the upper screw is hung on a connecting bolt B.

[0008] In a preferred embodiment of this invention, the threads on the lower screw and the upper screw have opposite structures.

[0009] In a preferred embodiment of this invention, nuts are installed on both the lower screw and the upper screw.

[0024] Example 1: As Figure 1-4The present invention provides a technical solution: including a crawling trolley 1 and a placement box 3. The crawling trolley 1 has a placement groove 2 at its upper end, and the placement box 3 is placed in the placement groove 2. The top rear side of the placement box 3 is hinged to a box cover 4 by a built-in hinge. The front sides of the box cover 4 are welded with first connecting blocks 5. The placement box 3 is welded with a second connecting block 7 below the first connecting block 5. The first connecting block 5 and the second connecting block 7 are threadedly connected with bolts 6.

[0025] Connecting seats A8 are welded to the middle of both sides of the crawling trolley 1, and connecting bolts A9 are threaded onto the connecting seats A8. Connecting seats B12 are welded to the upper side of the middle of both sides of the placement box 3, and connecting bolts B11 are threaded onto the connecting seats B12. A detachable connecting device 10 is installed between the connecting bolts A9 and B11.

[0026] The connecting device 10 includes a first hook 1001, which is hung on the connecting bolt A9. A lower screw 1002 is welded to the top of the first hook 1001. A threaded cylinder 1005 is fitted on the upper end of the lower screw 1002. An upper screw 1006 is threadedly connected to the upper end of the threaded cylinder 1005. A second hook 1007 welded to the upper end of the upper screw 1006 is hung on the connecting bolt B11.

[0027] The threads on the lower screw 1002 and the upper screw 1006 have opposite structures.

[0032] Working principle:

[0033] In use, place the placement box 3 in the placement slot 2, with the four limiting blocks 14 at the bottom of the placement box 3 positioned in the limiting slot 13. Then, thread the connecting bolt A9 into the connecting seat A8 and thread the connecting bolt B11 into the connecting seat B12. Next, hook the first hook 1001 at the bottom of the lower screw 1002 onto the connecting bolt A9 and hook the second hook 1007 on the upper screw 1006 onto the connecting bolt B11. By rotating the threaded cylinder 1005, the upper screw 1006 and the lower screw 1002 are screwed into the threaded cylinder 1005, thus securing the placement box 3 firmly. Then, place the goods and equipment into the placement box 3, and then close the box cover 4. Connect the first connecting block 5 and the second connecting block 7 with the bolt 6 to secure the box cover 4.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
