Description

Technical Field

[0001] This utility model relates to the field of rotary speed reducer technology, specifically to a rotary speed reducer used for transporting wind turbine blades. Background Technology

[0002] A rotary reducer is a full-circumferential rotary speed reduction transmission mechanism that integrates a drive power source. It uses a slewing bearing as the driven component and attachment component. By attaching the driving component, drive source, and housing to one of the inner and outer rings of the slewing bearing, and using the other ring as both the driven component and the connecting base of the driven working part, it utilizes the characteristic of the slewing bearing itself as a full-circumferential rotary connecting component to efficiently configure the drive power source and main transmission components. This makes it a general-purpose speed reduction transmission mechanism that integrates rotation, speed reduction, and drive functions, while also being simple in structure and easy to manufacture and maintain.

[0003] However, existing rotary reducers, due to their enclosed structure, make it difficult to add lubricant to the internal transmission parts. When the internal transmission components operate for a long time, the meshing parts will wear severely, which will affect the normal use of the reducer.

[0004] In view of this, the present invention proposes a rotary speed reducer for transporting wind turbine blades. Utility Model Content

[0005] This utility model proposes a rotary reducer for transporting wind turbine blades, which solves the problem that existing rotary reducers, due to their enclosed structure, are not easy to lubricate the internal transmission parts. As a result, long-term operation of the internal transmission components leads to severe wear of the meshing parts, which in turn affects the normal use of the reducer.

[0006] The technical solution of this utility model is as follows: A rotary reducer for transporting wind turbine blades includes a base, a protective box fixedly connected to the top of the base, a transmission motor fixedly connected to the base on one side of the protective box, a meshing screw fixedly connected to the output end of the transmission motor and rotatably connected to the protective box, a gear rotatably connected to the base at one end of the meshing screw, a rotary table fixedly connected to the top of the gear, a slot on one side of the protective box, a retaining plate slidably connected inside the slot, an assembly plate fixedly connected to one end of the retaining plate, an oil injection hole on the top of the assembly plate, a sliding plate slidably connected inside the assembly plate, a stop bar fixedly connected to the top of the sliding plate, a spring fixedly connected to the assembly plate on the side of the stop bar, a fixing plate slidably connected to the assembly plate at the tail of the spring, a fixing strip inserted into the protective box at one end of the assembly plate, a second screw embedded in the fixing strip threadedly connected to one end of the protective box, and a first screw embedded in the assembly plate threadedly connected to the inside of the fixing strip.

[0007] Preferably, the protective box has heat dissipation holes on both sides, and a protective pipe fixedly connected to the protective box is provided on the side of the heat dissipation hole.

[0008] Preferably, the card plate has a "T" shaped structure, and the card plate fits tightly with the card slot.

[0009] Preferably, when the card plate is fully embedded in the card slot, the assembly plate can completely cover the top of the protective box, and when the fixing strip is embedded in the protective box, it can fit tightly with the assembly plate.

[0010] Preferably, the oil injection hole is located at the meshing part of the engagement screw and the gear, and there are two sets of oil injection holes.

[0011] Preferably, the fixing plate is located on the movement trajectory of the stop bar, and the fixing plate is tightly fitted to the stop bar by a spring.

[0012] Preferably, the heat dissipation holes are arranged in a straight line at equal intervals in several groups.

[0013] Preferably, the protective tube is bent downwards, and the protective tube completely blocks the heat dissipation holes.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting an assembly plate, when it is necessary to inspect the inside of the protective box, the first screw and the second screw can be removed, and finally the fixing strip can be pulled out to the side. At this time, the fixing strip no longer fixes the assembly plate, and then the assembly plate can be pulled off. By setting an oil injection hole, when it is necessary to add lubricant to the meshing point of the meshing screw and gear, the sliding plate can be slid to the left to expose the oil injection hole. At this time, lubricant can be added through the oil injection hole, and the lubricant will drip onto the meshing point of the meshing screw and gear, so as to play a lubricating role.

[0016] 2. By setting heat dissipation holes, the heat inside the protective box can be dissipated more easily. By setting a protective tube with the end of the protective tube tilted downward, the dust prevention effect is further achieved, preventing dust from entering the equipment through the heat dissipation holes.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] A preferred embodiment of the rotary speed reducer for transporting wind turbine blades provided by this utility model is, for example... Figures 1 to 5 As shown: A rotary reducer for transporting wind turbine blades includes a base 1, a protective box 2 fixedly connected to the top of the base 1, a drive motor 3 fixedly connected to the base 1 on one side of the protective box 2, a meshing screw 4 rotatably connected to the protective box 2 fixedly connected to the output end of the drive motor 3, a gear 5 rotatably connected to the base 1 meshing at one end of the meshing screw 4, a rotary table 6 fixedly connected to the top of the gear 5, a slot 7 on one side of the protective box 2, a retaining plate 8 slidably connected inside the slot 7, and an assembly plate 9 fixedly connected to one end of the retaining plate 8. The top of the assembly plate 9 is provided with an oil injection hole 10. The slide plate 11 is slidably connected inside the assembly plate 9. The top of the slide plate 11 is fixedly connected with a baffle 12. The side of the baffle 12 is provided with a spring 13 fixedly connected to the assembly plate 9. The tail of the spring 13 is fixedly connected with a fixing plate 14 slidably connected to the assembly plate 9. One end of the assembly plate 9 is fitted with a fixing strip 15 inserted into the interior of the protective box 2. One end of the protective box 2 is threadedly connected with a second screw 17 embedded in the fixing strip 15. The fixing strip 15 is threadedly connected with a first screw 16 embedded in the interior of the assembly plate 9.

[0028] In this embodiment, the card plate 8 has a "T" shaped structure, and the card plate 8 fits tightly with the card slot 7, which can improve the stability of the card plate 8 after installation.

[0029] In this embodiment, when the card plate 8 is fully embedded in the card slot 7, the mounting plate 9 can completely cover the top of the protective box 2. When the fixing strip 15 is embedded in the protective box 2, it can fit tightly with the mounting plate 9. The top of the protective box 2 can be sealed by the card plate 8 to protect the internal components.

[0030] In this embodiment, the oil injection hole 10 is located at the meshing part of the screw 4 and the gear 5. There are two sets of oil injection holes 10. When lubricant needs to be added to the meshing part of the screw 4 and the gear 5, the sliding plate 11 can be slid to the left to expose the oil injection hole 10. Lubricant can then be added through the oil injection hole 10, and the lubricant will drip onto the meshing part of the screw 4 and the gear 5, thus providing lubrication. Figure 4This is a cross-sectional view of assembly plate 9. The slide plate 11 is in the open state, and the oil injection hole 10 is exposed. The fixing strip 15 is used to limit the slide plate 11 when it is open, preventing it from sliding completely into the assembly plate 9 and making it inconvenient to remove. Figure 1 The exact location of the skateboard 11 can be determined, and when the skateboard 11 slides to the left, it will only be hidden inside the mounting plate 9 and will not collide with the fixing strip 15.

[0031] In this embodiment, the fixing plate 14 is located on the movement trajectory of the baffle 12. The fixing plate 14 is tightly attached to the baffle 12 by the spring 13, closing the upper slide plate 11. The spring 13 also makes the fixing plate 14 and the baffle 12 tightly attached, thereby fixing the slide plate 11 and preventing dust from entering the protective box 2 from the oil injection hole 10. The fixing plate 14 is in a sliding connection state with the assembly plate 9 and can only slide laterally. The spring 13 is fixedly connected to the assembly plate 9, so no matter how the spring 13 bends, the fixing plate 14 can only slide laterally and will not bend due to the bending of the spring 13. Secondly, when the fixing plate 14 is pushed open, the spring 13 will be in a contracted state, accumulating elastic potential energy. When the fixing plate 14 is released, the spring 13 can quickly push the fixing plate 14 to the position where it is attached to the baffle 12, and apply a pushing force to the fixing plate 14 through its own elasticity, so that the fixing plate 14 will not easily slide without the interference of external forces.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the rotary speed reducer for transporting wind turbine blades provided by this utility model is, for example... Figures 1 to 5 As shown: both sides of the protective box 2 are provided with heat dissipation holes 18, and the sides of the heat dissipation holes 18 are provided with protective pipes 19 that are fixedly connected to the protective box 2.

[0034] In this embodiment, several groups of heat dissipation holes 18 are arranged in a straight line at equal intervals. By setting the heat dissipation holes 18, the heat inside the protective box 2 can be dissipated more easily.

[0035] In this embodiment, the protective tube 19 is bent downwards and completely blocks the heat dissipation hole 18. By setting the protective tube 19 with its end tilted downwards, it further achieves the dustproof effect and prevents dust from entering the equipment from the heat dissipation hole 18.

[0036] The working principle and usage process of this utility model are as follows: First, by setting the assembly plate 9, when it is necessary to inspect the inside of the protective box 2, the first screw 16 and the second screw 17 can be removed. Finally, the fixing strip 15 can be pulled out to the side, at which point the fixing strip 15 no longer fixes the assembly plate 9. Then, the assembly plate 9 can be pulled off and removed. By setting the oil injection hole 10, when it is necessary to add lubricant to the meshing joint of the engagement screw 4 and the gear 5, the sliding plate 11 can be slid to the left to expose the oil injection hole 10. At this time, lubricant can be added through the oil injection hole 10. When the lubricant is added, it drips onto the meshing position of the screw 4 and gear 5, providing lubrication. Then, the upper slide plate 11 is closed, and the fixing plate 14 and the baffle 12 are tightly fitted by the spring 13, thus fixing the slide plate 11 and preventing dust from entering the protective box 2 from the oil injection hole 10. By setting the heat dissipation hole 18, the heat inside the protective box 2 can be dissipated more easily. By setting the protective tube 19, the end of the protective tube 19 is inclined downward, which further improves the dust prevention effect and prevents dust from entering the equipment from the heat dissipation hole 18.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
