Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a hoisting platform for installing a wind turbine. Background Art

[0002] The installation of fans usually requires the use of a lifting platform, which is a kind of working platform used to provide a safe and stable work platform. For the installation of fans, the lifting platform can provide a stable platform so that workers can safely enter the installation location of the fan and perform necessary operations. The lifting platform is usually made of steel structure and has sufficient strength and stability to support the weight of personnel and equipment.

[0003] Chinese patent CN213265418U discloses a wind turbine hoisting platform, comprising a base, a pressure cap disposed above the base, a mounting groove disposed on the top of the base, a protrusion fixedly connected to the bottom of the pressure cap, the protrusion corresponding to the mounting groove, and the utility model relates to the field of wind power generation technology. The wind turbine hoisting platform achieves the goal of placing the base on the ground, adding a counterweight block to the base to increase the overall gravity, and at the same time, a metal rod disposed at the bottom of the counterweight block corresponds to a through hole, and the metal rod is mechanically pressed into the soil layer to compact the soil between the piles, thereby compacting the soil between the piles. At the same time, the metal rod extends into the soil layer to form a pile structure, thereby improving the overall stability. The pressure cap is then added to the base for installation, thereby improving installation efficiency. A fixing device is provided above the pressure cap to facilitate the installation of sleepers, thereby ensuring that the heights of the various support platforms are consistent, thereby improving the working stability of the crane and meeting the purpose of use requirements.

[0004] However, it was discovered during actual use that the device was installed on the lifting platform through the base and the gland, so that the fan could be hoisted by the crane.

[0005] However, since the base is placed directly on the ground, when the crane on the lifting platform is carrying a heavy wind turbine for lifting, the force borne on one side will be relatively large, causing the base and the pressure cover to tilt during use. This tilt will cause the lifting platform to be unable to maintain a horizontal position, thereby affecting the accuracy and safety of the wind turbine lifting. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-4As shown, a hoisting platform for installing a wind turbine includes a bottom support 1, a middle adjustment plate 2, and a hoisting platform 3 arranged in sequence from bottom to top. A plurality of sleepers 4 are provided between the bottom support 1 and the middle adjustment plate 2, and between the middle adjustment plate 2 and the hoisting platform 3. A plurality of first adjustment devices 5 are provided on the sides of the bottom support 1 and the middle adjustment plate 2, and a plurality of second adjustment devices 8 are provided between the middle adjustment plate 2 and the hoisting platform 3; the plurality of first adjustment devices 5 cooperate with the plurality of second adjustment devices 8 to achieve fine-tuning of the flatness of the hoisting platform 3.

[0027] The bottom support 1, the middle adjustment plate 2 and the lifting platform 3 are all made of low-alloy high-strength steel plates, which have good strength, plasticity and weldability.

[0028] The first adjusting device 5 is arranged at both ends of the bottom support 1 and the middle adjusting plate 2 in the length direction; the second adjusting device 8 is arranged at both ends of the middle adjusting plate 2 and the lifting platform 3 in the width direction, so as to avoid the first adjusting device 5 and the second adjusting device 8 being arranged at both ends of the length direction or both ends of the width direction at the same time, which may cause the entire lifting platform 3 to become unstable in a certain direction.

[0029] The first adjusting device 5 also includes a first articulated seat 6 and a first hydraulic cylinder 7; the bottom of the first articulated seat 6 is fixed to the bottom support 1, one end of the first adjusting device 5 is hinged to the first articulated seat 6, and the bottom of the other end of the first adjusting device 5 is fixed to the telescopic end of the first hydraulic cylinder 7; part of the middle part of the first adjusting device 5 presses upward against the bottom of the middle adjustment plate 2.

[0030] The second adjusting device 8 also includes a second articulated seat 9 and a second hydraulic cylinder 10; the bottom of the second articulated seat 9 is fixed to the middle adjusting plate 2, one end of the second adjusting device 8 is hinged to the second articulated seat 9, and the bottom of the other end of the second adjusting device 8 is fixed to the telescopic end of the second hydraulic cylinder 10; part of the middle part of the second adjusting device 8 is pressed upward against the bottom of the lifting platform 3.

[0031] The bottom of the bottom support 1 is provided with multiple fixed cone rods 11 extending downward, and the fixed cone rods 11 are provided with multiple connecting hooks 12. When the bottom support 1 is installed on the ground, the fixed cone rods 11 and the connecting hooks 12 will be inserted into the ground, further improving the stability of the bottom support 1.

[0032] A plurality of circular connecting rings 13 are provided on the side of the hoisting platform 3 . Connecting rods or steel cables are passed through the circular connecting rings 13 and fixed to the ground using anchors, thereby further improving the stability of the hoisting platform 3 .

[0033] At least one level detection device 14 is provided on the hoisting platform 3. In this embodiment, the level detection device 14 is a level sensor. By setting the level detection device 14, it is convenient to detect the hoisting platform 3. When the hoisting platform 3 tilts, personnel can discover it in time.

[0034] The top surfaces of the first adjusting device 5 and the second adjusting device 8 are provided with reinforcement blocks 15 to reinforce the first adjusting device 5 and the second adjusting device 8 so that the first adjusting device 5 and the second adjusting device 8 will not be deformed when the first hydraulic cylinder 7 and the second hydraulic cylinder 10 are jacked up.

[0035] Specifically, the above-mentioned wind turbine installation hoisting platform is implemented in the following manner:

[0036] First, install the bottom support 1 in a suitable position to support the hoisting platform 3. When the hoisting platform 3 does not need to be adjusted, it can be supported by the sleepers 4 and the first and second hydraulic cylinders 7 and 10 to improve the stability of the hoisting platform 3 and facilitate the crane on the hoisting platform 3 to hoist the wind turbine.

[0037] When the hoisting platform 3 tilts during use, the inclination of the hoisting platform 3 can be detected by the level detection device 14. When the inclination of the hoisting platform 3 exceeds the set range, the personnel can remove the sleepers 4 and start a group of first hydraulic cylinders 7 to lift it, while the other group of first hydraulic cylinders 7 retracts it. In this way, the hinged middle adjustment plate 2 will drive the hoisting platform 3 to adjust the front and rear angles, so that the hoisting platform 3 remains in a horizontal position.

[0038] In addition, a group of second hydraulic cylinders 10 can be started for jacking, while another group of second hydraulic cylinders 10 retracts to adjust the left and right tilt angles of the lifting platform 3 in the articulated state to ensure that the left and right surfaces are also maintained in a horizontal state. The device uses the coordinated work of the first hydraulic cylinder 7 and the second hydraulic cylinder 10, which not only makes the entire device structure simple and easy to operate, but also when personnel remove the sleepers 4 on the bottom support 1 or the middle adjustment plate 2, the support is maintained through the adjustment of the first hydraulic cylinder 7 and the second hydraulic cylinder 10, ensuring that the lifting platform 3 can still remain stably horizontal after the support is removed. This design greatly improves the stability and horizontal maintenance ability of the lifting platform 3, and provides reliable protection for lifting operations.

[0039] The above-mentioned specific implementation methods are used to explain the present invention and are only preferred embodiments of the present invention, rather than limiting the present invention. Within the spirit of the present invention and the scope of protection of the claims, any modifications, equivalent replacements, improvements, etc. made to the present invention shall fall within the scope of protection of the present invention.
