Description

Technical Field

[0001] The utility model relates to the technical field of wire laying tools, in particular to a wire laying tool for lightning arresters of wind power blades. Background Art

[0002] Wind turbine blades are the most basic and critical components of wind turbines. Since wind turbine blades are installed in open and high areas, their position is high and the probability of being struck by lightning is greater. Therefore, lightning conductors are installed on the belly plate inside the wind turbine blades for current transmission.

[0003] In order to achieve the laying and storage of lightning conductors, the Chinese utility model patent with publication number CN213833953U discloses a wind turbine blade lightning conductor laying tool. The anti-drop plate can effectively prevent the lightning conductor from falling off. The rotating shaft drives the reel to rotate, which makes it easier to unfold the lightning conductor and effectively improves work efficiency. At the same time, the support frame is fixedly connected to the web mold, and the unfolded lightning conductor can be placed on the support frame, effectively avoiding damage and pollution caused by the lightning conductor falling to the ground. However, during the use of the lightning conductor laying tool, it is necessary to pull the lightning conductor forward. When the length of the lightning conductor is long, the deadweight of the lightning conductor will gradually increase, which requires greater pulling force. When a large pulling force is applied to pull the lightning conductor, it is easy to cause damage or breakage of the lightning conductor core, affecting the quality of the lightning conductor.

In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] like Figures 1 to 6 As shown, the wind turbine blade lightning conductor laying tool of the utility model embodiment includes a workbench 1, a support frame 2, two driving support mechanisms and two clamping and conveying mechanisms, wherein the workbench 1 is fixedly mounted on the upper end of the support frame 2, wherein the workbench 1 is a rectangular plate, and the workbench 1 is used for laying out the lightning conductor.

[0033] Among them, two driving support mechanisms are respectively arranged on the left and right sides of the support frame 2, and each driving support mechanism includes a synchronous belt 3 and a plurality of driving support components arranged at intervals. Each driving support component includes a fixed shaft 4, a driving cylinder 5 rotatably mounted on the fixed shaft 4, and a passive gear 6 fixed to one end of the driving cylinder 5, and the passive gear 6 is meshed and connected with the synchronous belt 3. That is, under the transmission action of the synchronous belt 3, the passive gear 6 of each driving support component can be driven to rotate, thereby driving each driving cylinder 5 to rotate.

[0034] Among them, two clamping and conveying mechanisms are respectively arranged on the left and right sides of the support frame 2, and each clamping and conveying mechanism is correspondingly arranged above each driving support mechanism. Each clamping and conveying mechanism includes a conveyor belt 7 and a plurality of rotating clamps 8, and the plurality of rotating clamps 8 are sequentially arranged at intervals on the outer surface of the conveyor belt 7. That is, under the transmission action of the conveyor belt 7, each rotating clamp 8 can be driven to move synchronously with the conveyor belt 7.

[0035] The wind turbine blade lightning conductor laying tool of the utility model embodiment, when in use, clamps the lightning conductor through the rotating clamp 8, and then drives the conveyor belt 7 to run, thereby driving the lightning conductor forward through the rotating clamp 8. The lightning conductor falls under the action of gravity and falls on the surface of the driving cylinder 5. The driving cylinder 5 can support the lightning conductor. At the same time, under the driving action of the synchronous belt 3, each driving cylinder 5 can be driven to rotate. The rotation of each driving cylinder 5 can provide driving force for the lightning conductor, thereby reducing the pulling force on the lightning conductor when the rotating clamp 8 drives the lightning conductor forward, which can enhance the protection of the lightning conductor and prevent the core of the lightning conductor from being damaged or broken due to excessive pulling force.

[0036] When the length of the lightning conductor reaches a predetermined length, it is cut off. The cut lightning conductor is located on the driving cylinder 5 and can be transferred to the surface of the workbench 1 for wiring.

Among the rotating fixtures 8 that are not selected for use, the rotating block 801 is in a vertical direction, and the opening of the threading clamp groove 802 is upward. When the rotating fixture 8 is selected for use, the rotating block 801 needs to be rotated so that the rotating block 801 is in a horizontal direction, and the rotating fixture 8 that is selected for use is used to clamp the lightning conductor. When the lightning conductor is laid out, since the rotating fixture 8 that is not selected for use is in a vertical state, it can avoid collision with the lightning conductor.

[0039] Furthermore, a locking screw 803 for locking the lightning conductor is also provided on the threading clamping groove 802. The threading clamping groove 802 adopts a U-shaped block, and semicircular grooves are provided on the inner walls of the two opposite sides of the U-shaped block.

By rotating the locking screw 803, the length of the end of the locking screw 803 can be adjusted, thereby achieving the purpose of locking the lightning conductor.

A connecting shaft 806 is fixedly installed in the U-shaped mounting plate 804, and a shaft sleeve 807 is provided at one end of the rotating block 801, and the shaft sleeve 807 is rotatably matched with the connecting shaft 806, so as to realize the rotation of the rotating block 801 relative to the connecting shaft 806.

[0041] In some embodiments of the present invention, the driving support mechanism further includes a synchronous motor 9 and a driving gear 10 fixedly connected to the driving shaft of the synchronous motor 9, and the driving gear 10 is meshed and connected with the synchronous belt 3. That is, the synchronous motor 9 can drive the driving gear 10 to rotate, thereby driving the synchronous belt 3 to run.

[0042] Among them, the driving support mechanism also includes a driving box 11, the driving box 11 is installed on the support frame 2, the synchronous motor 9 is installed on the outside of the driving box 11, and the synchronous belt 3, the driving gear 10 and the passive gear 6 are respectively installed in the driving box 11 to play a shielding and protective role.

[0043] Specifically, the synchronous motor 9 is arranged at the middle position of the synchronous belt 3. The driving support mechanism also includes two driven gears (not shown) arranged at both ends of the synchronous belt 3, and the driven gears are meshed and connected with the synchronous belt 3. Each driven gear is fixedly mounted on a driven shaft, and the two ends of the driven shaft are respectively rotated in correspondence with the left and right inner walls of the driving box 11. That is, the synchronous motor 9 can drive the driving gear 10 to rotate, and the rotation of the driving gear 10 can drive the synchronous belt 3 to run, and then the two driven gears are respectively driven to rotate under the action of the synchronous belt 3, so as to realize the stable and reliable operation of the synchronous belt 3.

[0044] Specifically, one end of the fixed shaft 4 is connected and fixed to the left inner wall of the driving box 11, and the other end of the fixed shaft 4 passes through the right wall of the driving box 11 and extends to the outside of the driving box 11. The driving cylinder 5 is arranged outside the driving box 11, and the driving cylinder 5 and the synchronous motor 9 are respectively located on opposite sides of the driving box 11.

[0045] Among them, an upwardly bent anti-detachment hook 12 is fixedly connected to the other end of the fixed shaft 4. The anti-detachment hook 12 is provided to limit the lightning conductor and prevent the lightning conductor from slipping off the driving cylinder 5.

[0046] In some embodiments of the utility model, the clamping conveying mechanism also includes a conveying motor 13, a driving pulley 14 and a driven pulley 15.

[0047] The working principle of the wind turbine blade lightning arrester laying tool in the embodiment of the utility model is as follows:

[0048] Rotate the rotating block 801 of the rotating fixture 8 to flip the rotating block 801 from the vertical direction to the horizontal direction, then insert the lightning conductor into the threading clamp groove 802, and lock the lightning conductor through the locking screw 803. Then start the transmission motor 13 and the synchronous motor 9, and the conveyor belt 7 runs under the driving action of the transmission motor 13, so that the lightning conductor is driven forward by each rotating fixture 8 set on the conveyor belt 7, and the lightning conductor falls under the action of gravity and falls on the surface of the driving cylinder 5, and the driving cylinder 5 can support the lightning conductor. At the same time, under the driving action of the synchronous motor 9, each driving cylinder 5 is driven to rotate through the synchronous belt 3, so that the driving cylinder 5 provides driving force for the lightning conductor, and then when the rotating fixture 8 drives the lightning conductor forward, the pulling force on the lightning conductor is reduced, and the protection of the lightning conductor is improved, and the lightning conductor core is prevented from being damaged or broken due to excessive pulling force. When the length of the lightning conductor reaches the predetermined length, it is cut off, and the cut lightning conductor is located on the driving cylinder 5, and then the lightning conductor can be transferred to the surface of the workbench 1 for wiring.
