Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wind power generation, in particular to a load basket for lifting objects at high altitude of a wind turbine generator set. Background Technique
[0002] During the operation and maintenance of a wind turbine generator set, relevant equipment and tools need to be hoisted into the nacelle of the wind turbine at high altitude. In the past, the hoisting method was to load the tools and equipment into a sling bag and then use a hoist to hoist them into the nacelle of the wind turbine. However, because the sling bag is usually made of canvas weaving, when hoisting relatively sharp objects, it is easy to scratch them. Due to the upward force of the hoist, the scratched part of the load bag will be enlarged, resulting in the risk of equipment and tools falling from high altitude and personnel being injured by falling objects.
[0003] If an ordinary iron basket is used for hoisting, although the material is hard and not easy to damage, the problem of large equipment and tools falling from high altitude can be solved. However, due to its heavy weight, it is inconvenient to carry in actual work, resulting in a low utilization rate. At the same time, the pores around the iron basket are relatively large, and there is also a risk of falling when placing small tools. Moreover, there is no cover plate on the top of the basket to block it, so there is a risk of tipping over.
[0004] The above two facilities are the conventional load-hoisting facilities in the daily operation and maintenance work of a wind farm. However, in the actual use process, there may be potential safety hazards such as equipment damage and falling objects from high altitude, which affect the safe and stable operation of the wind turbine generator set and the risk of personal safety accidents. Content of the Utility Model
[0005] The purpose of the utility model is to solve the disadvantages of conventional hoisting facilities, minimize the potential safety hazards of equipment damage and personal safety accidents caused by hoisting facilities, and at the same time facilitate the use of on-site maintenance personnel, improve the hoisting efficiency of equipment and the safety of hoisting work. The utility model provides a load basket for lifting objects at high altitude of a wind turbine generator set.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] A load basket for lifting objects at high altitude of a wind turbine generator set includes an aluminum alloy box body 16.

A tilt-proof cover plate 11 is arranged on the top of the aluminum alloy box body 16 in an openable and closable manner. Two hinge A's 12 are symmetrically arranged at intervals on one side of the tilt-proof cover plate 11. Two hinge B's 166 are symmetrically arranged at intervals on a top rod 163 of the aluminum alloy box body 16. A locking device 13 is also arranged at the edge of one side of the tilt-proof cover plate 11.
[0008] The utility model also has the following additional technical features:
[0009] As a further specific optimization of the technical solution of the present utility model: The aluminum alloy box body 16 includes four vertical columns 161 arranged at the four corners.

[0016] Figure 2 It is an assembled structure schematic diagram of the present utility model. EMBODIMENTS
[0017] Hereinafter, exemplary embodiments disclosed by the present utility model will be described in more detail with reference to the drawings.
[0018] A load basket for high-altitude lifting of a wind turbine generator set includes an aluminum alloy box body 16. The aluminum alloy box body 16 is made of aluminum alloy, and the main frame of the aluminum alloy box body 16 is 500mm * 490mm * 500mm, which can reduce the weight of the hanging basket and is convenient for handling at the same time.
[0019] The aluminum alloy box body 16 includes four vertical columns 161 located at the four corners. Four bottom bars 162 are welded to the bottoms of the four columns 161. After placing a wire mesh 14 between the four bottom bars 162, a bottom plate 165 is welded and arranged; four top bars 163 are welded to the tops of the four columns 161, and a number of vertical bars 164 are vertically welded between the top bars 163 and the bottom bars 162; the columns 161, bottom bars 162, top bars 163 and vertical bars 164 together form a frame structure; the bottom of the aluminum alloy box body 16 is closed and the top is open.
[0020] Lifting lugs 15 are respectively welded and arranged at the tops of the four columns 161 of the aluminum alloy box body 16. The four lifting lugs 15 can make the pulling force during lifting be in the central position, improving the overall stability of the load basket.
[0021] A wire mesh 14 in a cubic shape is installed inside the aluminum alloy box body 16. Both the bottom and the top of the wire mesh 14 are open. The wire mesh 14 is provided with smaller mesh holes, which can reduce the pores of the vertical bars 164 of the load basket, enabling small tools or utensils and relatively sharp items to be placed in the load basket. The wire mesh 14 can ensure that the items in the load basket will not fall.
[0022] An anti-tipping cover plate 11 is provided in a switchable manner at the top of the aluminum alloy box body 16. Two hinge A's 12 are symmetrically arranged at intervals on one side of the anti-tipping cover plate 11. Two hinge B's 166 are symmetrically arranged at intervals on one of the top bars 163 of the aluminum alloy box body 16. The two hinge A's 12 and the two hinge B's 166 are connected by a pin shaft and used in cooperation with each other, enabling the anti-tipping cover plate 11 to be flexibly opened.
[0023] A locking device 13 is further provided at one side edge of the anti-tipping cover plate 11. The locking device 13 can lock the anti-tipping cover plate 11 to prevent the items in the load basket from falling.
[0024] Usage method of the load basket for high-altitude lifting of wind turbine generators:
[0025] Step 1. When installing the wire mesh 14, the whole of the four columns 161 and the four bottom bars 162 can be turned over and placed, then the wire mesh 14 is placed into the openings of the four bottom bars 162, then the bottom plate 165 is placed between the four bottom bars 162 for welding, and finally the whole is turned back, and the wire mesh 14 can be placed inside the aluminum alloy box body 16. After the wire mesh 14 is placed inside the aluminum alloy box body 16, it can be used normally without taking it out. When carrying out high-altitude hoisting work of wind turbine generators, open the anti-tipping cover plate 11 at the top of the load basket and place large equipment and large tools to be hoisted into the aluminum alloy box body 16. It is also possible to open the anti-tipping cover plate 11 at the top of the load basket and place small equipment and small tools into the wire mesh 14.
[0026] Step 2. After the placement is completed, cover the anti-tipping cover plate 11 and lock the locking device 13. The locking device 13 is a bolt, which is the most common locking device. The bolt body A is installed on the side of the anti-tipping cover plate 11, and the socket B is installed on one side of the ejector rod 163, and the bolt body A and the socket B are installed correspondingly. When the bolt body A is pulled outwards, the locking device 13 is opened, and at this time, the anti-tipping cover plate 11 can be turned over and opened through the hinge member hinge A12. After the anti-tipping cover plate 11 is closed, push the bolt body A inwards, the locking device 13 is closed, and the anti-tipping cover plate 11 can be locked to prevent the items in the carrying basket from falling.
[0027] Step 3. Pass the sling through the four lifting lugs 15 provided on the carrying basket, and after confirming that the sling is fastened and balanced, use the hoist to complete the high-altitude hoisting work of the wind turbine generator.
