[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 3 The modular blade main beam rapid positioning device shown is arranged on a mounting frame at the tip of the blade, and includes a positioning component 1 and a calibration component 2. The positioning component 1 is arranged at the lower part of the blade tip; the calibration component 2 is arranged at the upper part of the blade tip; wherein, the positioning component 1 includes a base 11 and a positioning column 12 for rapid positioning, and the positioning column 12 is arranged on the top of the base 11; the calibration component 2 includes two parallel brackets 21, a beam 22 connecting the brackets 21, and a calibration tube 23 arranged in the middle of the beam 22 and perpendicular to the beam 22, and is coaxially arranged with the positioning column 12 through the calibration tube 23.

[0028] The implementation process of this utility model is as follows Figure 2 As shown, after the crossbeam is opened around the bracket, the blade main beam is installed and positioned according to the positioning posts on the base. When positioning is complete, the crossbeam is closed around the bracket and the calibration tube on the crossbeam is coaxially arranged with the positioning posts to achieve dual positioning. The beneficial effect of this utility model is that the precise alignment of the positioning posts and the calibration tube can ensure high-precision positioning of the blade main beam during installation, reduce errors, and improve overall manufacturing quality.

[0029] In the present invention, the bottom of the positioning post 12 is embedded in the top of the base 11, and a retaining ring 121 extends around the bottom of the positioning post 12. This embedding of the positioning post 12 into the top of the base 11 creates a tight, embedded connection that is more stable than simple support or fixation, effectively resisting deformation or displacement under external forces. The design of retaining ring 121 further strengthens the connection between the positioning post 12 and the base 11. Even under external forces, the positioning post 12 is unlikely to fall off the base 11, ensuring the overall stability of the device.

[0030] As a preferred embodiment of the above embodiment, an end cap 3 is further provided on the top of the base 11, and a through hole is provided in the center of the end cap 3 to accommodate the passage of the positioning column 12. The fixed connection between the end cap 3 and the base 11 provides additional support and fixation for the positioning column 12, forming a double guarantee with the embedded connection method, making the position of the positioning column 12 on the base 11 more stable. The design of the end cap 3 helps to reduce the loosening of the positioning column 12 due to long-term use or external forces, thereby ensuring the long-term stable operation of the device. The end cap 3 is usually designed to be detachable. When the positioning column 12 needs to be maintained or replaced, the end cap 3 can be easily removed for operation, reducing the difficulty and cost of maintenance.

[0031] As a preference of the above embodiment, the diameter of the through hole is smaller than the diameter of the fixing ring 121 , which can prevent the positioning column 12 from falling off in the base 11 and effectively provide protection.

[0032] As a preferred embodiment of the above, a support assembly 4 is further provided on the periphery of the base 11 and at the lower part of the end cover 3; the support assembly 4 includes a support plate 41 and two L-shaped connecting plates 42, the L-shaped connecting plates 42 are fixedly connected to the support plate 41 by bolts, and the two L-shaped connecting plates 42 are fixed to the side walls of the base 11 by long bolts passing through the inside of the base 11. The addition of the support assembly 4 provides an additional support point for the base 11, which helps to disperse the load-bearing pressure generated by the device during operation and reduce the risk of deformation and damage to the base 11. The design of the support assembly 4 helps to reduce the vibration generated by the device during operation, protect internal parts from vibration damage, and improve the stability and reliability of the device. At the same time, since the long bolts pass through the inside of the base, they can also play a certain supporting role on the bottom of the positioning column 12.

[0033] In the present invention, a positioning slot 122 is further provided on the upper surface of the positioning post 12. The presence of the positioning slot 122 enables more precise positioning of the positioning post 12 when coupled with a mating component, enabling rapid positioning while also ensuring repeatable positioning accuracy. The presence of the positioning slot 122 also simplifies and speeds up the installation process. Operators simply align the mating component with the positioning slot 122 and insert it, eliminating the need for complex adjustments and calibration.

[0034] In the present invention, one end of a crossbeam 22 is movably connected to one of the brackets 21, allowing crossbeam 22 to rotate about bracket 21. Within a limited space, adjusting the angle of crossbeam 22 allows for more efficient use of space, avoids interference with other components or equipment, and improves the rationality of the overall layout. This also prevents interference with crossbeam 22 during main beam installation.

[0035] As a preferred embodiment of the above, the other end of the crossbeam 22 is connected to the other bracket 21 via bolts. This bolted connection simplifies and expedits the installation of the crossbeam 22. Operators simply align the crossbeam with the bolt holes on the bracket and tighten the bolts to complete the connection, reducing installation difficulty and time. If the crossbeam 22 needs to be rotated, simply remove the bolts to perform the operation.

[0036] In the present invention, the calibration tube 23 is fixedly connected to the crossbeam 22 via a connecting ring 6 disposed in the middle of the crossbeam 22. This central location provides a stable and precise mounting position for the calibration tube 23, helping to maintain a constant relative position between the calibration tube 23 and the crossbeam 22, thereby improving calibration accuracy and reliability. This fixed connection prevents positional drift of the calibration tube 23 during use due to factors such as vibration and loosening, thereby reducing calibration errors caused by positional variations.

[0037] In the present invention, the two brackets 21 are connected to other components via the support frame 5. When subjected to external forces, the support frame 5 can provide additional support and fixation to prevent the brackets 21 and beams and other components from deformation or displacement, thereby maintaining the stability and shape accuracy of the overall structure.

[0038] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
