Description

Technical Field

[0001] This utility model relates to the field of hoisting vehicles, and more specifically, to a wind power hoisting machine suitable for hoisting wind turbine generators at a height of 160 meters or more. Background Technology

[0002] This machine is a specialized hoisting device designed specifically for wind turbine installation, addressing inherent safety and efficient hoisting during the process. It contributes to the development of green energy.

[0003] Globally, wind turbine installation primarily relies on crawler cranes, truck cranes, and modified tower cranes. These three types of machinery are traditionally used for lifting in other industries, and none of them adequately address the inherent safety and efficiency requirements of wind turbine installation. Truck cranes can quickly move the turbine to a location and rapidly deploy and retract themselves to mitigate the impact of sudden wind upswings, but their low safety factor has led to the toppling of many large and extra-large truck cranes during wind turbine installations. Crawler cranes offer a higher safety factor than truck cranes, but they cannot provide timely wind protection during installation and require large assembly areas. The turbines also need to be disassembled and reassembled during relocation, significantly impacting installation efficiency.

[0004] To address the technical problems existing in the prior art, this application provides a wind turbine hoisting machine, which includes a tracked walking mechanism (1), outriggers (20), a traveling underframe (13), a vertical tower (15), a boom vertical sliding platform (6), a telescopic boom (8), a hydraulic system (7), and a torque balancing system (16). The four tracks (12) of the tracked walking mechanism (1) drive the main unit to move as a whole. The four tracks (12) are hydraulically independently suspended, and each track (12) can be controlled individually or in combination to achieve small-radius turning and crab-like movement of the track (12). When passing through inclined roads, the independent suspension system can ensure that the upper body of the machine is in a horizontal state, ensuring the safety of the overall movement of the equipment. The slewing platform (14) is used for rotating the vertical tower (15) and installing the winch (21). The boom vertical sliding platform (6) adopts a rapid up-and-down movement as a whole, and then uses the traction energy of the winch (21) to drive the boom and the upper platform to move up and down. The vertical tower (15) is quickly installed and disassembled by the self-lifting of the rear boom. The boom and the upper platform move up and down quickly as a whole, and the hydraulic system (7) completes the boom luffing.

[0005] However, traditional hoisting and installation equipment has a low safety factor. Raising and lowering the tower requires coordinated machinery and cannot be done independently, resulting in the toppling of many large and super-large truck cranes during wind turbine installation. Existing technology cannot provide timely wind protection during hoisting and requires large assembly sites. The turbine needs to be disassembled and reassembled during relocation, significantly impacting hoisting efficiency. Existing technology also requires substantial manpower and resources for site relocation, is time-consuming, and incurs excessive costs. Summary of the Invention

[0023] In some embodiments, the boom is placed on a sliding platform fitted on the vertical tower (15). The sliding platform is raised or lowered rapidly by a hoisting mechanism consisting of the boom placed on the top of the vertical tower (15) and the pulley block on the sliding platform, using a winch (21) provided on the slewing platform (14).

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The present application is described in detail below. In the following paragraphs, different aspects of the embodiments are more specifically defined. Such defined aspects may be combined with any other aspect or combinations thereof, unless expressly stated that they are not combined. In particular, combinations of features considered preferred or advantageous are noted.

[0043] In the description of this application, it should be understood that the terms "inner," "outer," "upper," "lower," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0044] Combination Figures 1 to 8 As shown, the wind turbine hoisting machine includes: a crawler walking mechanism (1), outriggers (20), a traveling base frame (13), a slewing platform (14), a vertical tower (15), a boom vertical sliding platform (6), a telescopic boom (8), a hydraulic system (7), and a torque balancing system (16).

[0045] The tracked traveling mechanism (1) includes four tracks (12), each track (12) is equipped with an independent suspension hydraulic system (7); outriggers (20); a traveling underframe (13) connected to the tracked traveling mechanism (1); a slewing platform (14) for fixing the winch (21) and counterweight; a vertical tower (15); a boom vertical sliding platform (6) connected to the vertical tower (15); a telescopic boom (8) including a first boom (10) erected on the boom vertical sliding platform (6) and connected to the boom vertical sliding platform (6) to swing the boom vertical sliding platform (6) in the vertical plane, and a second boom (9) hinged to the end of the first boom (10) away from the boom vertical sliding platform (6); a hydraulic system (7); a torque balancing system (16); wherein the wind turbine hoisting machine includes two telescopic booms (8) that complete the rapid installation and dismantling of the vertical tower (15) through self-lifting.

[0046] In this practical example, the boom hinge point is located at the rear, allowing the boom to lift and dismantle its own tower, and enabling the upper platform and boom to move up and down quickly as a whole. This improves upon the time-consuming and labor-intensive dismantling and long relocation times found in related technologies.

[0047] The wind turbine hoist is characterized by a two-section telescopic boom (8) that can quickly install and dismantle the vertical tower (15) by self-lifting. The boom vertical sliding platform (6) is moved vertically to a suitable position for dismantling. Each section of the vertical tower (15) is placed on the boom vertical sliding platform (6) by a hook and temporarily fixed. The boom vertical sliding platform (6) can be connected to the vertical tower (15) by a pin.

[0048] The tracked walking mechanism (1) is equipped with four tracks (12). The four tracks (12) are hydraulically independently suspended. Each track (12) can be controlled individually or in combination to achieve small-radius turning and crab-walking of the track (12). When passing through inclined roads, the independent suspension system (30) can ensure that the upper body is in a horizontal state, ensuring the safety of the overall movement of the equipment.

[0049] A winch (21) is installed on the traveling base frame (13) to control the rapid vertical movement of the rotary table (14) and the telescopic boom (8), eliminating the need for additional manpower to climb the tower for operation.

[0050] The telescopic boom (8) has its hinge point positioned behind the center of rotation for quick disassembly and installation of the vertical tower (15) with a self-installation / disassembly function.

[0051] The counterweight system at the rear of the traveling base (13) uses a front and rear torque balancing system (16) to achieve torque balance between the front and rear of the equipment, thereby ensuring that the front and rear torques are balanced when hoisting wind power equipment, ensuring that the tower body is not affected by bending moment, and achieving free height.

[0052] The boom vertical sliding platform (6) is connected to the two-section telescopic boom (8) by a pin.

[0053] The telescopic boom (8) and the boom vertical sliding platform (6) move up and down quickly as a whole. When moving, the boom is pulled up and down quickly as a whole by the winch (21) through the boom vertical sliding platform (6) and the vertical tower (15) above the telescopic boom (8).

[0054] The telescopic boom (8) uses hydraulic cylinders for luffing.

[0055] The wind turbine hoisting machine proposed in this application is mainly used for hoisting wind power equipment under high safety factor, easily relocating the site, and can quickly install and dismantle a 150-meter vertical tower (15) through self-hoisting, and hoist wind turbine generators at a height of 160 meters or more. In a specific practical example, the wind turbine hoisting machine consists of a crawler (12) traveling mechanism (1), a slewing platform (14), a boom vertical sliding platform (6), a vertical tower (15), a boom vertical sliding platform (6), a telescopic boom (8), and a hydraulic system (7).

[0056] The hoist in this embodiment has four tracks (12) welded to the vehicle chassis for relocation. It is suitable for traveling on complex roads and has a short relocation time and high efficiency.

[0057] Specifically, four retractable outriggers (20) are welded to the vehicle chassis and consist of vertical outriggers (20) and horizontal outriggers (20). They are used to provide support during operation and are retracted to both sides of the track (12) crane when moving to different locations.

[0058] Secondly, the traveling frame (13) is fixed to the vehicle chassis by bolts, and the vertical tower (15) is connected to the traveling frame (13) by bolts, so that the entire vertical tower (15) can rotate relative to the hoisting machine; a torque balancing system (16) is installed on the traveling frame (13), which can automatically adjust the weight of the counterweight when the working crane is hoisting, so that the overall torque is balanced, the tower body is not affected by bending moment, and safety is guaranteed; a winch (21) is also installed on the traveling frame (13) to control the rapid rise and fall of the boom.

[0059] The vertical tower (15) is fixed on the traveling base frame (13), and the vertical tower (15) and the traveling base frame (13) rotate simultaneously.

[0060] In some real-world examples, the boom can be quickly lowered to the bottom when the wind is strong.

[0061] In some practical examples, the outriggers (20) support the entire fuselage for a fixing function, and the boom vertical sliding platform (6) is fitted onto the vertical tower (15). Through the lifting mechanism consisting of the boom at the top rear of the vertical tower (15) and the pulley block on the boom vertical sliding platform (6), and the winch (21), the boom vertical sliding platform (6) and the telescopic boom (8) are moved up and down, realizing the rapid rise and fall of the boom. The boom vertical sliding platform (6) is used to place the individual towers removed during the self-lifting of the telescopic boom (8). After the self-lifting is completed, the height and position of the telescopic boom (8) are adjusted by swinging and raised to different heights by the vertical movement of the boom vertical sliding platform (6). When raised to a suitable height, the vertical tower (15) is temporarily fixed with pins and the hinge point is placed at the rear. The telescopic boom (8) lifts the first section of the tower removed and places it on the boom vertical sliding platform (6). When lowered to a suitable height, the vertical tower (15) is quickly disassembled section by section. Similarly, it can also be quickly installed.

[0062] In some practical examples, before the wind turbine hoisting machine is moved, the telescopic boom (8) moves vertically to quickly disassemble the vertical tower (15) section by section from top to bottom. Finally, the telescopic boom (8) is retracted, the torque balance system (16) is manually disassembled, and then the relocation is carried out. The outriggers (20) are raised and retracted, and the machine body moves through the tracks (12) of the traveling frame (13). The four tracks (12) can extend and rotate flexibly and are equipped with hydraulic independent suspension. Each track (12) can be controlled individually or in combination to achieve small-radius turning and crab-walking of the track (12). When passing through inclined, muddy or irregular road surfaces, the independent suspension system () can ensure that the upper body is in a horizontal state. It can be used on both narrow and wide roads at the same time, with fewer road requirements and fewer traffic restrictions. The disassembled vertical tower (15) is transferred at the same time using other transportation tools to achieve rapid relocation. Figures (5) and (6) show the different forms of the track sections of the wind turbine hoisting machine on different road surfaces.

[0063] In some embodiments, after reaching the working area, the wind turbine hoist extends its outriggers (20) to fix the body, and at the same time installs the disassembled torque balancing system (16). The boom vertical sliding platform (6) is lowered to the appropriate position at the bottom, and a section of vertical tower (15) is lifted by the hook of the telescopic boom (8) and installed in the appropriate position. After the pin is fixed, the vertical tower section is installed in the same way multiple times so as to quickly and with less manpower to be put into the construction process.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above examples. The examples and descriptions indicate the principles of this application, and various changes and modifications can be made without departing from the spirit and scope of this application. All such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
