Detailed Description

The present invention will be described in detail with reference to the accompanying drawings, and as shown in fig. 1-2, a ladder for maintaining a wind turbine tower comprises a wind turbine tower 1 and an entrance door 2 disposed thereon. Both sides of the entrance door 2 are provided with guard plates 3, when workers rise, the guard plates 3 are arranged on both sides of the workers, and therefore the workers are protected. The guard plates 3 are fixed on the fan tower barrel 1, a support plate 4 is connected between the two guard plates 3 in a sliding mode, and a worker stands on the support plate 4 and then moves up and down under the driving of the power mechanism 5. The support plate 4 is fixedly connected with the output end of the power mechanism 5, and the power mechanism 5 drives the support plate 4 to move up and down.

One side of the guard plate 3, which is opposite to the fan tower barrel 1, is provided with a folding ladder stand 6. When the electric lifting device is used, the folding crawling ladder 6 is in a folding state and is in contact with the protection plate 3, so that ascending or descending workers are protected on one hand, and space is saved on the other hand.

The protective plate 3 extends downwards from the upper part of the entrance door 2 to the ground, so that workers can be protected all the way. Be provided with on the backplate 3 along vertical direction's spout 7, backup pad 4 middle part is provided with arch 8, arch 8 inlays in spout 7. The bulge 8 of the supporting plate 4 is embedded in the sliding groove 7, so that the supporting plate 4 can move up and down more stably.

The power mechanism 5 comprises two motors 9 fixed on the fan tower barrel 1, and the motors 9 drive the supporting plate 4 to move up and down. The two motors 9 are respectively arranged above the two guard plates 3, the output ends of the motors 9 are fixedly connected with one ends of steel wire ropes 10, and the other ends of the steel wire ropes 10 are fixed on the bulges 8. The steel cord 10 is in the vertical direction. The output end of the motor 9 rotates the steel wire rope 10 to be wound on the output end of the motor 9, and the supporting plate 4 rises. When the output end of the motor 9 rotates reversely, the steel wire rope 10 winds the output end of the motor 9, and the support plate 4 descends.

The fan tower barrel 1 is provided with a support frame 15, and the support frame 15 is arranged below the entrance door 2. When meeting unexpected circumstances such as power failure, can not use motor 9 to drive backup pad 4 and go up and down to realize during staff's lift, the staff need climb folding cat ladder 6, and support frame 15 is used for supporting footboard 14, and folding cat ladder 6's top and entrance door 2 are connected to footboard 14, and the staff steps on footboard 14 and gets into entrance door 2 when climbing to folding cat ladder 6 top.

The folding crawling ladder 6 comprises a crawling ladder upper main body 11 and a crawling ladder lower main body 12, wherein the crawling ladder upper main body 11 and the crawling ladder lower main body 12 are connected through a 180-degree lockable hinge 13. The 180-degree lockable hinge 13 can be used for ensuring that the ladder stand upper main body 11 and the ladder stand lower main body 12 can be folded or extended, the 180-degree lockable hinge 13 is in a locked state when the hinge is extended, and the ladder stand upper main body 11 and the ladder stand lower main body 12 cannot shake or shift when climbing.

The ladder lower body 12 is folded upwardly to be parallel to the ladder upper body 11. At this time, the ladder lower main body 12 is folded upward in parallel with the ladder upper main body 11, saving space and not blocking the way of the worker into the support plate 4.

The ladder lower body 12 is deployed downwardly at 180 ° to the ladder upper body 11. Folding cat ladder 6 is in the state of expanding this moment, and the staff can climb folding cat ladder 6 and get into entrance door 2.

The top of the ladder stand upper part main body 11 is hinged on the guard plate 3, and the top of the ladder stand upper part main body 11 is hinged with a pedal 14. The hinge that can lock is adopted between cat ladder upper portion main part 11 and the backplate 3, when guaranteeing that cat ladder upper portion main part 11 is parallel with backplate 3, cat ladder upper portion main part 11 is locked to guarantee that cat ladder upper portion main part 11 plays the effect of the staff of protection station in backup pad 4.

The ladder stand upper main body 11 is parallel to the guard plate 3, and the pedal 14 is parallel to the ladder stand upper main body 11. When the folding crawling ladder 6 is not needed, the crawling ladder upper main body 11 is parallel to the guard plate 3, and the upper part of the folding crawling ladder 6 is in a folding state.

The angle between the ladder stand upper main body 11 and the guard plate 3 is more than or equal to 20 degrees and less than or equal to 60 degrees, and the pedal 14 is turned over to be in contact with the support frame 15. When the folding crawling ladder 6 needs to be used, the crawling ladder upper main body 11 is separated from the guard plate 3, the folding crawling ladder 6 is in an inclined state, and therefore safety is high and operation is easy when workers climb.

In the embodiment, two motors 9 are adopted to drive the support plate 4 to move upwards, so that the movement process of the support plate 4 is more stable; the foldable crawling ladder 6 is adopted, so that the foldable crawling ladder is folded when not used, the space is saved, workers standing on the supporting plate 4 and ascending or descending can be protected, the foldable crawling ladder 6 is stretched when the foldable crawling ladder is used, the foldable crawling ladder 6 is in an inclined state, the workers can conveniently climb, and the safety is good; set up two backplate 3, the whole journey of in-process staff that backup pad 4 rises or descends is in between two backplate 3, and the security is higher, protect the staff.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
