Description

Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] As Figure 1 shown, the embodiment provides a stacking transport tool convenient for hoisting of wind power blades, which comprises a plurality of blade root support units 1 arranged in a matrix structure and a plurality of middle blade support units 2 arranged in a matrix structure, and the number of the blade root support units 1 and the middle blade support units 2 is consistent and one-to-one corresponding, and the blade root support units 1 and the middle blade support units 2 are respectively used for supporting the blade root part and the middle blade part of the blade 3. The embodiment takes the stacking transport tool stacked in 3*3 layers as an example.

[0031] As Figure 2 shown, the blade root support unit 1 comprises a blade root support 101, a blade root support assembly 102 and a first transmission mechanism 103. The blade root support assembly 102 is used for fixing the blade root part of the blade and is detachably installed on the first movable cross beam assembly at the bottom of the blade root support 101. The first transmission mechanism 103 is in transmission connection with the first movable cross beam assembly. The first transmission mechanism 103 drives the first movable cross beam assembly to drive the blade root support assembly 102 to overturn upward, so as to avoid affecting the hoisting operation of the lower blade. The middle blade support unit 2 comprises a middle blade support 201, a middle blade clamping assembly 202 and a second transmission mechanism 203. The middle blade clamping assembly 202 is used for clamping the middle blade part of the blade and is installed in the middle of the middle blade support 201. The second transmission mechanism 203 is in transmission connection with the second movable cross beam assembly at the bottom of the middle blade support 201. The second transmission mechanism 203 drives the second movable cross beam assembly of the middle blade support 201 to overturn upward, so as to avoid affecting the hoisting operation of the lower blade.

[0032] As Figure 3As shown, the blade root support 101 comprises four first vertical beams 1011, two first horizontal longitudinal beams 1012, a first horizontal cross beam 1013 and a first movable cross beam assembly. The four first vertical beams 1011 are arranged in pairs in a left-right symmetrical manner, and the bottom of each pair of first vertical beams 1011 is connected by a first horizontal longitudinal beam 1012. The bottom front sides of the two pairs of first vertical beams 1011 are connected by the first horizontal cross beam 1013. Each first horizontal longitudinal beam 1012 and first horizontal cross beam 1013 is connected to the corresponding first vertical beam 1011 by a sleeve. The first movable cross beam assembly is arranged between the bottom of the two pairs of first vertical beams 1011 and located at the rear side of the first horizontal cross beam 1013. One end of the first movable cross beam assembly is hinged to the first horizontal longitudinal beam 1012 on the left side, and the other end is detachably connected to the first horizontal longitudinal beam 1012 on the right side by a limiting pin. The first transmission mechanism 103 is installed on the first horizontal cross beam 1013 and is in transmission connection with the first movable cross beam assembly. When hoisting the blade, the limiting of the limiting pin is released, and then the first transmission mechanism 103 drives the first movable cross beam assembly to drive the blade root support assembly 102 to overturn upward to a vertical state, and the lower blade can be hoisted in turn.

The other end of the two first support cross beams 1014 is detachably connected to the first horizontal longitudinal beam 1012 on the right side by the two limiting pins. When the limiting pins are locked, the blade root support assembly 102 can be stably placed on the first movable cross beam assembly.

[0034] To facilitate personnel passage and installation work, walkways 1017 are arranged between the two first support cross beams 1014 and between the two first horizontal longitudinal beams 1012.

[0035] The blade root support assembly 102 comprises a shape-preserving ring body 1021 and a support base 1022. The support base 1022 is detachably installed on the first movable cross beam assembly, and the shape-preserving ring body 1021 is installed on the top of the support base 1022. The top surface of the shape-preserving ring body 1021 forms an arc-shaped structure that can be fitted with the outer periphery of the blade root, thereby protecting the blade from damage caused by unstable oscillation during transportation. The shape-preserving ring body 1021 can be installed on the blade root support 101 after the assembly of the shape-preserving ring body 1021 and the support base 1022 is completed in the workshop, thereby saving time consumption during the blade transportation and installation process.

[0036] As shown in the drawings, Figure 5As shown, the support 201 in the blade includes four second vertical beams 2011, two second horizontal longitudinal beams 2012, a support longitudinal beam 2013 and a second movable cross beam assembly, the two second vertical beams 2011 in each group are symmetrically arranged, the bottom of each group of second vertical beams 2011 is connected by a second horizontal longitudinal beam 2012, and the middle of the second vertical beams 2011 on the left is connected by the support longitudinal beam 2013, each second horizontal longitudinal beam 2012 is connected with the corresponding second vertical beam by a sleeve, the second movable cross beam assembly is arranged between the bottoms of the two groups of second vertical beams 2011, one end of the second movable cross beam assembly is hinged with the second horizontal longitudinal beam 2012 on the left, and the other end of the second movable cross beam assembly is detachably connected with the second horizontal longitudinal beam 2012 on the right through a limiting pin, a second transmission mechanism 203 is installed on the second horizontal longitudinal beam 2012 and is in transmission connection with the second movable cross beam assembly, when hoisting the blade, the limiting of the limiting pin is released, then the second movable cross beam assembly is driven upward by the second transmission mechanism 203 to avoid affecting the hoisting operation of the lower blade.

[0037] As shown in Figure 6 The second movable cross beam assembly includes two second support cross beams 2014, a second hinged rod 2015, two second one-way hinges 2016 and two limiting pins, one end of the two second support cross beams 2014 is connected with the second hinged rod 2015, the second hinged rod 2015 is hinged with the second horizontal longitudinal beam 2012 on the left through the two second one-way hinges 2016, and the second hinged rod 2015 is in transmission connection with the second transmission mechanism 203, the other end of the two second support cross beams 2014 is detachably connected with the second horizontal longitudinal beam 2012 on the right through the two limiting pins.

[0038] As shown in Figure 7As shown, the blade clamping assembly 202 includes a support crossbar 2021, a third hinge rod 2022, a third one-way hinge 2023, two hydraulic systems 2024, a conformal airfoil 2025, and a third transmission mechanism 2026. One end of the support crossbar 2021 is connected to the third hinge rod 2022. The third hinge rod 2022 is connected to the support longitudinal beam 2013 in the middle of the blade support 201 via the third one-way hinge 2023. The conformal airfoil 2025 is disposed at the other end of the support crossbar 2021. The conformal airfoil 2025 includes two clamping bodies that are hinged to each other. The two clamping bodies are arranged vertically, and each clamping body is hinged to a hydraulic system. System 2024, hydraulic system 2024 is hinged to the middle of support crossbar 2021. Two hydraulic systems 2024 drive the opening and closing of two clamping bodies. When the hydraulic rods of hydraulic system 2024 retract, due to the constraint of degrees of freedom, the clamping bodies of conformal airfoil 2025 gradually rotate around the hinge axis, that is, gradually open. Conversely, they gradually fit against the outer edge of the blade, realizing the clamping of the blade. The third transmission mechanism 2026 is set on the support longitudinal beam 2013 and is connected to the third hinge rod 2022. The design of the third transmission mechanism 2026 is to rotate the blade clamping assembly 202 as a whole, saving the space occupied by the design. The third transmission mechanism can be used as a backup system. If there are operational restrictions and space constraints when the clamping bodies on the lower side of conformal airfoil 2025 open downward, it can be considered to rotate the entire assembly out through the third transmission mechanism when the clamping bodies are open or re-fitted. In this way, the hoisting of the lower blade is not interfered with by the blade clamping assembly 202.

[0039] To facilitate the movement of people between different floors, escalators 400 are installed between two adjacent leaf root support units 1 and between two adjacent leaf middle support units 2.

[0040] In this embodiment, the first, second, and third transmission mechanisms have the same structure. Taking the first transmission mechanism 103 as an example, as follows: Figure 8 As shown, it consists of a rotary motor 1031, a rotary motor end gear 1032, a synchronous transmission belt 1033, and a hinge rod end gear 1034. The rotary motor rotates, driving the rotary motor end gear to rotate, which in turn drives the hinge rod end gear to rotate via the synchronous transmission belt, thereby realizing the rotation of the first movable crossbeam assembly, the second movable crossbeam assembly, and the leaf clamping assembly.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed in this utility model patent, based on the technical solution and utility model patent concept of this utility model patent, shall fall within the protection scope of this utility model patent.
