Description

Technical Field

[0001] The utility model relates to the field of wind power blade manufacturing, in particular to a main beam hanging beam tooling with a self-unloading function. Background Art

[0002] As the global demand for clean energy continues to grow, wind power generation, as a renewable energy technology, has been rapidly developed and widely used. In recent years, the unit power of wind turbines has continued to increase, and the size of blades has also increased significantly to capture more wind energy and improve power generation efficiency. Large wind turbine blades can be tens of meters or even hundreds of meters long, and their manufacturing process is complex, which places higher requirements on production accuracy and efficiency.

[0003] Wind turbine blades are usually made of composite materials, and their main beam is the core structure that bears the main load of the blade. During the blade shell laying process, the prefabricated main beam needs to be accurately hoisted into the mold, which places high demands on the safety, efficiency and positioning accuracy of the hoisting equipment.

[0004] In order to solve the problem of hoisting large wind turbine components, there are some hanging beam structures in the prior art. For example, Chinese patent document CN114148888A discloses a lifting hanging beam for installing a wind turbine nacelle. The technical solution of the hanging beam (hereinafter referred to as "Document 1") is: a plurality of pin holes are arranged at the bottom of the main beam, and the positive secondary beam and the lateral secondary beam are fixed to the main beam through the pins to form a stable frame structure. The hanging beam is suspended on the hook through the lifting ears and slings arranged at both ends of the main beam.

[0005] However, the solution in Document 1 mainly solves the problem of lifting large components. Its structural design does not fully consider the requirements of accurate positioning of the main beam in the mold and safe and fast unloading. It has the following technical problems:

[0006] Insufficient safety: In the solution of Document 1, both the fixing and unloading of the main beam require manual operation of shackles or other connecting mechanisms, which requires workers to operate under the hanging beam, posing a major safety hazard.

[0007] Low efficiency: Due to the lack of automatic unloading mechanism, the unloading process of the main beam is cumbersome, requiring more time and manpower, reducing production efficiency.

[0008] Limited positioning accuracy: In the solution of Reference 1, the positioning accuracy of the main beam mainly depends on manual operation and visual inspection, which is difficult to meet the needs of high-precision positioning. Since the main beam is connected to the hanging beam only by pins and lifting ears, it is easy to shake during the lifting process, which will affect the positioning accuracy. Utility Model Content

[0009] In order to overcome the defects existing in the prior art, the utility model provides a main beam lifting beam tooling with a self-unloading function, which utilizes a vacuum suction cup to assist in fixing the main beam, thereby achieving safe, efficient and precise lifting of the main beam.

[0010] The utility model solves the above technical problems through the following technical solutions:

[0011] A main beam lifting beam tooling with a self-unloading function, comprising a frame body, a vacuum suction cup arranged on the frame body, and a vacuum pipeline connected to the vacuum suction cup, characterized in that it also comprises: a protective sling, the two ends of which are respectively connected to the protective sling electric-controlled hooks on both sides of the frame body; a vacuum control device, the vacuum control device comprising a vacuum pump and a ventilation electromagnetic switch connected to the vacuum pipeline; wherein the protective sling electric-controlled hook and the ventilation electromagnetic switch can respectively control the opening of the protective sling and the closing of the vacuum suction cup by remote control. Remote control operation can realize remote control, avoid personnel operating under the lifting beam, improve safety, and the operation is convenient and quick, which improves the unloading efficiency.

[0012] Preferably, the protective sling comprises a sling body and an electric shackle arranged on the sling body. By arranging the electric shackle on the sling body, the protective sling can be quickly and reliably disengaged.

[0013] Preferably, the frame body is provided with a plurality of mounting holes for mounting the vacuum suction cup, and the vacuum suction cup is arranged on the frame body through the mounting holes. By providing mounting holes on the frame body, the vacuum suction cup can be flexibly installed and removed, adapting to main beams of different sizes and shapes, and enhancing the flexibility of the structure.

[0014] Preferably, the vacuum suction cup includes a suction cup body and a vacuum cavity provided on the suction cup body, wherein the vacuum cavity is connected to a vacuum pipeline. By providing the vacuum cavity on the suction cup body and connecting it to the vacuum pipeline, the negative pressure generated by the vacuum pump can be transferred to the suction cup surface to achieve vacuum adsorption, so that it can be effectively connected to the vacuum pipeline to form a vacuum adsorption force.

[0015] Preferably, the ventilation electromagnetic switch is connected to the vacuum chamber of the vacuum chuck to control the connection between the vacuum chamber and the vacuum pipeline and the outside gas. By connecting the ventilation electromagnetic switch to the vacuum chamber of the vacuum chuck, the vacuum chamber can be selectively connected to the vacuum pipeline or the outside atmosphere by controlling the opening and closing of the ventilation electromagnetic switch, thereby realizing the control of the suction and release of the vacuum chuck.

[0016] Preferably, the electric hooks of the protective sling are arranged on both sides of the frame body and outside the vacuum suction cup. The electric hooks of the protective sling are arranged outside the vacuum suction cup to avoid interference with the vacuum suction cup when operating the protective sling, while ensuring a safe distance for the operator.

[0017] Preferably, the frame body includes a plurality of interconnected cross beams and a plurality of interconnected vertical beams, and the vacuum suction cup is mounted on the cross beams. The structure in which the cross beams and the vertical beams are interconnected can improve the strength and stability of the frame body, so that it can withstand the weight of the main beam and various stresses during the hoisting process.

[0018] The utility model realizes safe, efficient and accurate lifting of the main beam by setting up components such as protective slings, vacuum suction cups, and vacuum control devices. In particular, the coordinated use of protective slings and vacuum suction cups can not only provide reliable load-bearing capacity, but also control their separation by remote control, thus avoiding the risk of personnel operating under the beam, and effectively solving the problems of insufficient safety, low efficiency, and limited positioning accuracy in the prior art.

[0021] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] Figure 1 This is a structural schematic diagram of a main beam hanging beam tooling with a self-unloading function according to an embodiment of the utility model. Figure 2 This is a schematic structural diagram of a main beam hanging beam tooling with a self-unloading function after being rotated 90° along a horizontal plane in one embodiment of the utility model.

[0023] like Figure 1-2 As shown, the main beam lifting beam tooling with self-unloading function of the utility model comprises a frame body 1 , a vacuum suction cup 3 arranged on the frame body 1 , and a vacuum pipeline 2 connected to the vacuum suction cup 3 .

[0024] Among them, the frame body 1 is the main load-bearing structure of the beam lifting fixture, and its structural strength and stability are directly related to the safety of lifting. In this embodiment, the frame body 1 includes a plurality of interconnected cross beams and a plurality of interconnected vertical beams, and the cross beams and vertical beams can be made of steel structures or other high-strength materials to ensure their load-bearing capacity. The vacuum suction cup 3 is arranged on the cross beam of the frame body 1, and is used to adsorb the main beam, provide auxiliary load-bearing capacity and positioning function, and further improve the safety of lifting. The vacuum pipeline 2 is used to connect the vacuum suction cup 3 and the vacuum control device, which can adopt a flexible pressure-resistant pipeline, such as a rubber tube or a plastic tube.

[0025] In order to realize safe and reliable lifting of the main beam, the utility model is further provided with a protective lifting belt 5 and a vacuum control device.

[0026] The function of the protective sling 5 is to provide additional safety protection to prevent the main beam from accidentally falling when the vacuum suction cup 3 has not been firmly adsorbed or an unexpected situation occurs. The vacuum control device includes a vacuum pump 6 and a ventilation electromagnetic switch 4 connected to the vacuum pipeline 2. The vacuum pump 6 is used to generate negative pressure, and the negative pressure is transmitted to the vacuum suction cup 3 through the vacuum pipeline 2, so that it is adsorbed on the surface of the main beam. The ventilation electromagnetic switch 4 is used to control the connection between the vacuum chamber and the vacuum pipeline 2 and the external gas, so as to realize the control of the adsorption and release of the vacuum suction cup 3.

[0027] Furthermore, in order to improve the convenience and safety of operation, the electric hook 7 of the protective sling and the ventilation electromagnetic switch 4 can be controlled by remote control. The operator can control the opening of the protective sling 5 and the closing of the vacuum suction cup 3 respectively by remote control from a safe distance, avoiding the risk of personnel operating under the hanging beam, improving the safety of operation, simplifying the operation process, and improving work efficiency.

[0028] The two ends of the protection strap 5 are respectively connected to the protection strap electric-controlled hooks 7 on both sides of the frame body 1 .

[0029] Furthermore, the protective sling 5 includes a sling body and an electric shackle arranged on the sling body. By arranging the electric shackle (not shown in the figure) on the sling body, the protective sling 5 can be quickly and reliably disengaged. The sling body can be made of high-strength fiber materials, such as nylon slings or steel wire ropes, to ensure its load-bearing capacity. The electric shackle can be electromagnetic or motor-type, which can be controlled by a remote control signal, thereby realizing remote and rapid disengagement of the protective sling 5.

[0030] Furthermore, the frame body 1 is provided with a plurality of mounting holes (not shown in the figure) for mounting the vacuum suction cup 3. The vacuum suction cup 3 is arranged on the frame body 1 through the mounting holes. By providing mounting holes on the frame body 1, the vacuum suction cup 3 can be flexibly installed and removed, adapting to main beams of different sizes and shapes, and enhancing the flexibility of the structure.

[0031] Furthermore, the vacuum suction cup 3 includes a suction cup body and a vacuum cavity (not shown in the figure) arranged on the suction cup body, and the vacuum cavity is connected to the vacuum pipeline 2. By arranging the vacuum cavity on the suction cup body and connecting it to the vacuum pipeline 2, the negative pressure generated by the vacuum pump 6 can be transferred to the suction cup surface to achieve vacuum adsorption, so that it can be effectively connected to the vacuum pipeline 2 to form a vacuum adsorption force.

[0032] Furthermore, the ventilation electromagnetic switch 4 is connected to the vacuum chamber of the vacuum suction cup 3 to control the connection between the vacuum chamber and the vacuum pipeline 2 and the outside gas. By connecting the ventilation electromagnetic switch 4 to the vacuum chamber of the vacuum suction cup 3, the vacuum chamber can be selectively connected to the vacuum pipeline 2 or the outside atmosphere by controlling the opening and closing of the ventilation electromagnetic switch 4, thereby realizing the control of the adsorption and release of the vacuum suction cup 3.

[0033] Furthermore, the electric hook 7 of the protective sling is arranged on both sides of the frame body 1 and outside the vacuum suction cup 3. The electric hook 7 of the protective sling is arranged outside the vacuum suction cup 3 to avoid interference with the vacuum suction cup 3 when operating the protective sling 5, while ensuring a safe distance for the operator, thereby improving the safety of the operation.

[0034] Furthermore, the frame body 1 includes a plurality of interconnected cross beams and a plurality of interconnected vertical beams, and the vacuum suction cup 3 is mounted on the cross beams. The structure in which the cross beams and the vertical beams are interconnected can improve the strength and stability of the frame body 1, so that it can withstand the weight of the main beam and various stresses during the hoisting process, thereby ensuring the safety of the hoisting process.

[0035] The working process of the utility model is as follows:

[0036] The beam lifting fixture is hoisted above the main beam, and the position of the beam lifting fixture is adjusted so that the vacuum suction cup 3 is aligned with the predetermined suction position of the main beam.

[0037] The vacuum pump 6 is started, and the vacuum suction cup 3 is adsorbed on the surface of the main beam under the action of negative pressure.

[0038] The two ends of the protection strap 5 are respectively hung on the protection strap electric control hooks 7 on both sides of the frame body 1.

[0039] Lift the main beam and move it over the mold.

[0040] When the main beam is about to be placed in the mold, the electric hook 7 of the protective sling is controlled by the remote controller to open the electric shackle and loosen the protective sling 5.

[0041] Continue to slowly lower the beam until it is precisely positioned in the mold.

[0042] The vacuum pump 6 is turned off, and the ventilation electromagnetic switch 4 is controlled by the remote controller to connect the vacuum cavity of the vacuum suction cup 3 with the outside atmosphere, thereby releasing the adsorption state of the vacuum suction cup 3.

[0043] Remove the lifting beam tooling and complete the lifting of the main beam.

[0044] In summary, the utility model provides a main beam lifting beam tooling with a self-unloading function, which realizes safe, efficient and accurate lifting of the main beam by setting components such as protective slings, vacuum suction cups, and vacuum control devices, and adopting remote control. In particular, the coordinated use of protective slings and vacuum suction cups can not only provide reliable carrying capacity, but also control their separation separately by remote control, avoiding the risk of personnel operating under the lifting beam, and effectively solving the problems of insufficient safety, low efficiency and limited positioning accuracy existing in the prior art.
