Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0023] Example 1

[0024] like Figure 1 and Figure 2As shown in the figure, this embodiment discloses an automatic loading and unloading hook fixture for large wind turbine blades, which is applied in the blade industry. It is a device that is fixed on large equipment and fixtures for lifting equipment and fixtures.

[0025] The automatic loading and unloading hook tooling for large wind turbine blade equipment includes an outer base plate 5, on which a guide sleeve 4 is provided.

[0026] This embodiment has two spaced-apart outer substrates 5. The two outer substrates 5 are connected as a whole by a fixed side plate 10, and a receiving space 502 is formed between the two outer substrates 5. The receiving space 502 is used to accommodate a crane hook 9, and the crane hook 9 can descend into the receiving space 502. Specifically, the outer substrate 5 is a thin plate with an outer surface, an inner surface, a top edge, a bottom edge, and two side edges 501. In this application, the surfaces of the two outer substrates 5 facing each other are referred to as the inner surface.

[0027] The guide sleeve 4 extends outward from the outer substrate 5 and penetrates the outer substrate 5 vertically to communicate with the receiving space 502.

[0028] The fixed side plate 10 is welded to the two sides 501 of the two outer substrates 5. Because the sides 501 extend at an angle, the fixed side plate 10 is also in an angled state. The two sides 501 of the two outer substrates 5 are connected by the two fixed side plates 10.

[0029] Multiple connection holes 11 are arranged at the bottom of the outer substrate 5. The connection holes 11 are connected to the intelligent end milling machine through pins. The center of gravity of the equipment is controlled by adjusting the position of the pins.

[0030] The automatic loading and unloading hook fixture for large wind turbine blade equipment in this embodiment also includes a pin 1, a connecting rod 2, a lifting shaft 3, and an electric push rod 12. The electric push rod 12, also known as a linear actuator, is a new type of linear actuator mainly composed of a motor push rod and a control device.

[0031] The connecting rod 2 is welded to the guide sleeve 4 or the outer base plate 5. The connecting rod 2 is connected and fixed to the electric push rod 12 by a pin 1. Specifically, the connecting rod 2 is perpendicular to the outer surface of the outer base plate 5. The electric push rod 12 is also perpendicular to the outer surface of the outer base plate 5. The pin 1 is perpendicular to the connecting rod 2 and the electric push rod 12. The electric push rod 12 is connected to the lifting shaft 3 by bolts. The lifting shaft 3 is also perpendicular to the outer base plate 5 and passes through the guide sleeve 4. The electric push rod 12 can drive the lifting shaft 3 to reciprocate along the guide sleeve 4. The lifting shaft 3 can move forward into the receiving space 502 to engage with the crane hook 9, or the lifting shaft 3 can move backward out of the receiving space 502 to disengage from the crane hook 9.

[0032] This embodiment also includes a guide assembly for guiding the overhead crane hook 9 and a height adjustment assembly for adjusting the height of the overhead crane hook 9. The guide assembly makes it easy for the overhead crane hook 9 to enter a preset position that mates with the lifting shaft 3. For overhead crane hooks 9 of different types and sizes, the height of the overhead crane hook 9 needs to be adjusted by the height adjustment assembly to ensure reliable mating with the lifting shaft 3.

[0033] Specifically, the automatic loading and unloading hook fixture for large wind turbine blade equipment in this embodiment also includes a threaded plate 6, an adjusting screw 7, and a guide plate 8.

[0034] The threaded plate 6 is horizontally positioned within the accommodating space 502. The threaded plate 6 is a rectangular plate structure. It is welded to the inner surface of the outer base plate 5. An adjusting screw 7 is threaded onto the threaded plate 6; rotating the adjusting screw 7 changes its height. The top surface of the adjusting screw 7 serves as a contact surface, used to contact and support the overhead crane hook 9. When the overhead crane hook 9 descends to touch the top surface of the adjusting screw 7, it signifies that the overhead crane hook 9 has reached the preset position for engagement with the lifting shaft 3. At this point, the lifting shaft 3, driven by the electric push rod 12, moves towards the overhead crane hook 9 to engage with it, enabling reliable lifting.

[0035] This embodiment includes two inclined guide plates 8, which are located in the receiving space 502 and welded to the inner side of the outer base plate 5. The two guide plates 8 are located above the threaded plate 6 to guide the descent of the crane hook 9 so that the crane hook 9 can reach the top surface of the adjusting screw 7 and be in a preset position that can cooperate with the lifting shaft 3.

[0036] The operator slowly places the overhead crane hook 9 along the guide plate 8, with the bottom of the overhead crane hook 9 flush with the top surface of the adjusting screw 7. The electric push rod 12 is operated by the button, and the electric push rod 12 drives the hoisting shaft 3 to move along the guide sleeve 4 toward the overhead crane hook 9, so as to achieve the connection with the overhead crane hook 9.

[0037] In this embodiment, the overhead crane hook 9 has a hook-shaped structure, and the hoisting shaft 3 can be inserted into the hook-shaped area of ​​the overhead crane hook 9.

[0038] In this embodiment, the width of the outer substrate 5 gradually decreases and then gradually increases from top to bottom. The outer substrate 5 also has a perforated structure to reduce its weight.

[0039] Example 2

[0040] The difference between this embodiment and embodiment 1 is that the structure of the crane hook 9 in this embodiment is different from that in embodiment 1.

[0041] like Figure 3As shown, the crane hook 9 in this embodiment has a plug-in hole. Under the drive of the electric push rod 12, the hoisting shaft 3 enters the plug-in hole of the crane hook 9 to achieve hooking with the crane hook 9.

[0042] Compared to existing technologies, the automatic loading and unloading hook fixtures for large wind turbine blade equipment disclosed in Embodiments 1 and 2 are more automated, eliminating the need for personnel to climb and ensuring operator safety. The cooperation between the lifting shaft 3 and the overhead crane hook 9 is more reliable, thereby improving lifting safety.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
