[0028] Example 1
[0029] like Figure 1-Figure 7 As shown,
[0030] A wind turbine blade transport support device includes a base, a support assembly, a placement assembly and a binding and fixing device. The support assembly is arranged directly above the base 1. The support assembly includes a support plate 2. An elastic buffer device is arranged between the bottom of the support plate 2 and the base 1. The elastic buffer device includes hydraulic buffers arranged at the four corners of the bottom of the support plate 2 and a buffer spring arranged at the center of the bottom of the support plate 2. The base 1 is fixed on a transport vehicle. By arranging the hydraulic buffer and the buffer spring, when the support plate 2 is subjected to pressure, a safety buffer can be provided to prevent damage to the mechanism caused by a hard collision.
[0031] The placement assembly is arranged above the support plate 2, and the placement assembly includes a placement plate 7, a telescopic plate 6 and a connecting plate 5, one end of the telescopic plate 6 is fixedly connected to the connecting plate 5, and the other end of the telescopic plate 6 is slidably connected to the placement plate 7. Specifically, a sliding groove is provided inside the placement plate 7, and the telescopic plate 6 is inserted into the sliding groove of the placement plate 7 and can slide in the sliding groove.
[0032] Anti-slip blocks are fixedly connected to both sides of one end of the telescopic plate 6 connected to the placement plate 7, and the telescopic plate 6 is slidably connected to the placement plate 7. When the placement plate 7 and the connecting plate 5 are adjusted in inclination, the telescopic plate 6 automatically slides and adjusts with the placement plate 7. The anti-slip blocks can prevent the telescopic plate 6 from slipping out of the placement plate 7 when sliding, so as to ensure the stability of the angle adjustment of the connecting plate.
[0033] A pair of support rods 3 and a pair of hydraulic telescopic rods 4 are arranged between the placement assembly and the support plate 2. The bottoms of the two support rods 3 are fixedly connected to the support plate 2, the tops of the two support plates 3 are hingedly connected to the connecting plate 5, the bottoms of the two hydraulic telescopic rods 4 are fixedly connected to the support plate 2, and the tops of the two hydraulic telescopic rods 4 are hingedly connected to the placement plate 7.
[0034] The hydraulic telescopic rod 4 is located at the lower end of one end of the placement plate 7. The output ends of the two hydraulic telescopic rods 4 are respectively hingedly connected to the bottom surface of the placement plate 7. Starting the hydraulic telescopic rod 4 drives the placement plate 7 to tilt upward, and at the same time pulls the connecting plate 5 to adjust synchronously to adjust the support angle of the blade to facilitate subsequent transportation.
[0035] A groove for placing the fan blades is provided on the top of the placement plate 7, and fixing plates are provided on both sides of the placement plate 7. A binding and fixing device is provided on the placement plate 7, and the binding and fixing device includes a double-axis motor 8, a reel 11 and a binding rope 12 arranged on both sides of the placement plate 7. The double-axis motor 8 is fixed to the fixing plate on the placement plate 7. A transmission belt 10 is sleeved on both output ends of the double-axis motor 8, and one end of the two transmission belts 10 on the same side is sleeved with the same reel 11, and a group of binding ropes 12 is centrally arranged on the opposite surfaces of the two reel 11.
[0036] The winding shaft 11 is located inside the placement plate 7, and the winding shaft 11 is movably connected to the placement plate 7. The two ends of the binding rope 12 are respectively fixedly connected to the two winding shafts 11. One end of the blade is placed inside the groove on the top surface of the placement plate 7. Then, the two dual-axis motors 8 are started, and the transmission belt 10 is cooperated to make the two winding shafts 11 rotate synchronously in opposite directions. The rotation of the winding shaft 11 reels the binding rope 12, thereby achieving fixed limiting of the blade.
[0037] A ratchet 17 is also fixed on the output shaft of the dual-axis motor 8, and a pawl 18 cooperating with the ratchet is hingedly connected to the placement plate 7. The cooperation between the ratchet 17 and the pawl 18 can ensure that the dual-axis motor drives the binding rope 12 to contract and tighten the fan blades when rotating, and the binding effect of the binding rope 12 can be ensured by the action of the ratchet pawl 18. When the binding rope 12 needs to be loosened, the pawl 18 is manually pushed away from the ratchet 17, and the dual-axis motor 8 is turned on in the reverse direction to loosen the binding rope 12.
[0038] Two sets of guide mechanisms 9 are arranged on the inner side of the placement plate 7. The guide mechanisms 9 include a fixed block 13 fixedly connected to the inner side of the placement plate 7. A pair of movable shafts 14 are movably connected to the inner side of the fixed block 13. A guide groove 15 is provided in the middle of the movable shaft 14. A toothed ring 16 is fixedly connected to both ends of the movable shaft 14. In order to ensure the winding stability of the binding rope 12 and avoid the problem of winding and knotting, the guide mechanism 9 is arranged. The two toothed rings 16 located on the same side are meshed and connected. The guide groove 15 fits the surface of the binding rope 12. During the winding process, the binding rope 12 rubs against the guide groove 15, thereby rotating the movable shaft 14. The toothed ring 16 is matched to ensure the rotation stability of the corresponding two movable shafts 14, and guides the binding rope 12.
[0039] When the utility model is in use:
[0040] First, the base 1 is fixedly placed on the transport vehicle, and then one end of the blade is placed in the groove on the top surface of the placement plate 7 through the lifting equipment. Then, the two dual-axis motors 8 are started, and the transmission belts 10 are cooperated to make the two winding shafts 11 rotate synchronously in opposite directions. The rotation of the winding shaft 11 reels the binding rope 12, thereby achieving fixed positioning of the blade.
[0041] During the winding process, the binding rope 12 rubs against the guide groove 15, thereby rotating the movable shaft 14, and cooperating with the gear ring 16 to ensure the rotation stability of the two corresponding movable shafts 14, guiding the binding rope 12 and preventing it from being entangled and knotted.
[0042] Due to the large length of the blades, the space requirement during transportation is relatively high. At this time, the hydraulic telescopic rod 4 is started to drive the placement plate 7 to tilt upward, and at the same time, the connecting plate 5 is pulled to adjust synchronously to adjust the support angle of the blade to facilitate subsequent transportation. When the placement plate 7 and the connecting plate 5 are adjusted in inclination, the telescopic plate 6 automatically slides with the placement plate 7 to ensure the stability of the connecting plate angle adjustment.
[0043] The utility model sets a placing plate to be inclined and raised, and pulls the connecting plate for synchronous adjustment at the same time. When the placing plate and the connecting plate are adjusted in inclination, the telescopic plate automatically slides and adjusts with the placing plate, so that the supporting angle of the blades can be adjusted, so that the blades are arranged in an inclined state during transportation, reducing the space requirement during subsequent transportation and facilitating the transportation of the blades.
[0044] The utility model arranges a transmission belt to make the winding shaft rotate and reel in the binding rope, thereby achieving fixed limiting of the blades. During the winding process, the binding rope rubs against the guide groove, thereby causing the movable shaft to rotate, and cooperates with the gear ring to ensure the rotation stability of the corresponding two movable shafts. Compared with the prior art, irregularly shaped blades are fixed by binding, which improves the fixing effect of the blades and guides the binding assembly to avoid the problem of entanglement and knotting.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
