If the specific posture changes, the directional indication will also change accordingly.

[0019] If the description of "first" or "second" and the like is involved in the embodiments of the utility model, the description of "first" or "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features.Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.In addition, the technical features (including but not limited to structure, material or characteristics, etc.) of each embodiment can be combined arbitrarily, in order to make the description simple, each technical feature in the embodiments is not described all possible combinations, however, as long as the combination of these technical features does not exist contradiction, it should be considered that it is within the scope of the description.

[0020] As shown in Figures 1-3 A holding pole positioning device, comprising a pole body 2 vertically arranged in the tower body 1, the top of the pole body 2 is provided with a "Y" type of bifurcated pole 4 for supporting the guide sling 3, the bifurcated pole is provided with a sliding rail 5, and the bifurcated pole is provided with a buffer mechanism 6 between the pole body. As shown in Figure 4 The bifurcated part of the bifurcated pole 4 can also be directly connected with the buffer mechanism 6, and the opening angle of the bifurcated pole 4 is adapted to the opening of the uppermost tower body. The holding pole positioning device skillfully uses the symmetrical structure of the tower body frame, so that the sling connected to the tower body frame can quickly slide to the bifurcated part at the center of the bifurcated pole along the sliding rail when placed in the bifurcated pole, realizing rapid and accurate positioning, thereby improving the installation efficiency. At the same time, the buffer mechanism can play a buffering role in the process of installing the tower body frame structure, effectively avoiding the damage to the tower body structure and the installation equipment caused by the impact force generated by the sudden stress or release of the sling.

[0021] The buffer mechanism 6 is a gas pump or a hydraulic pump, which can effectively reduce mechanical impact and vibration and play an effective buffering protection role, and further, the hydraulic pump can be an oil pump.

[0022] The pole body 2 is assembled by a plurality of frame structures, so that the pole body can be flexibly adjusted according to actual needs, and the holding pole positioning device of the utility model is installed in the tower body during use, and the pole body of the device can also be raised synchronously with the gradual increase of the tower body, and the assembly process is simple and fast.

[0023] The rod body is fixed in the installed tower body frame through the upper pull line 7 and the lower pull line 8. Specifically, the upper pull line 7 is composed of four steel ropes, one end of which is fixed to the top of the rod body, and the other end of which is fixed to the installed tower body frame node. The lower pull line 8 is composed of four steel ropes, one end of which is fixed to the bottom of the rod body, and the other end of which is fixed to the middle of the installed tower body frame. The arrangement of the upper pull line and the lower pull line makes the rod body more stable in the tower body frame. The upper pull line is composed of four steel ropes, one end of which is fixed to the top of the rod body, and the other end of which is fixed to the installed tower body frame node, which can effectively prevent the rod body from tilting during lifting and ensure the stability of the lifting process. The lower pull line is composed of four steel ropes, one end of which is fixed to the bottom of the rod body, and the other end of which is fixed to the middle of the installed tower body frame, which makes the tower body main material and foundation bear force evenly, further enhances the stability of the whole structure, and ensures the safety and reliability of the rod body.

[0024] As shown in Figure 5 The tower construction method using the unmanned aerial vehicle modular transportation and hoisting of the pole holding device in place comprises the following steps:

[0025] S1, assemble the tower material into several frame structures constituting the tower body in advance at the unmanned aerial vehicle takeoff site;

[0026] S2, connect the frame structure of the tower body to the unmanned aerial vehicle through a sling, and transport it by the unmanned aerial vehicle;

[0027] S3, use the unmanned aerial vehicle to transport the frame structure at the bottom of the tower body to the designated installation position and fix and install it;

[0028] S4, set up a pole holding device in place inside the frame structure at the bottom of the tower body, which can rise with the tower body, the pole holding device in place comprises a rod body vertically placed inside the tower body, a "Y" type bifurcated rod at the top of the rod body for supporting and guiding the sling, a sliding rail mounted on the bifurcated rod, and a buffer mechanism between the bifurcated rod and the rod body;

[0029] S5, suspend the hanging point of the frame structure of the tower body to the bifurcated rod at the top of the pole holding device in place by means of the unmanned aerial vehicle, release the sling onto the bifurcated rod, slide to the center under the guidance of the sliding rail, and then slowly lower the two frame structures to be connected and installed through the buffer mechanism to fix and install them, so as to realize accurate installation of the tower body in place.

[0030] Further, the following steps are included: after the installation of the frame structure of one section of the tower body is completed, the height of the pole holding device in place is raised, and then the step S5 is repeated to assemble the frame structure of the next section of the tower body, until the installation of the whole tower body is completed. During the installation process, the verticality and the levelness of the tower body can be more accurately controlled by gradually raising the pole holding device in place and installing the tower body in sections, so as to ensure the stability and safety of the tower body structure.

[0031] Furthermore, in step S5, after the tower frame structure is smoothly placed on the gantry positioning device, the drone releases the slings via the automatic unhooking device and then returns to the takeoff site to prepare for the next tower frame structure lifting operation. The automatic unhooking device is a conventional existing structure that automatically releases the slings upon reaching the designated position without manual intervention, reducing operation time and improving the efficiency of tower material transportation and installation.

[0032] The tower assembly method utilizing modular transportation and hoisting by drones pre-assembles tower materials into several frame structures at the drone takeoff site, achieving modular assembly. This allows the tower materials to form relatively complete and stable units during the assembly stage, reducing the amount of assembly work on the construction site. Compared to traditional manual handling or large machinery transportation, drones offer greater flexibility and mobility, enabling them to quickly traverse complex terrain without being limited by ground conditions, significantly shortening transportation time and accelerating the overall construction progress. Simultaneously, the drone suspends the tower frame structure at the top of the gantry crane, achieving precise positioning, releasing the slings onto the gantry crane, and guiding it down the guide rails to achieve centered positioning. The tower frame structure is then slowly raised and lowered to its original position via a buffer mechanism, ensuring precise installation and avoiding repeated adjustments and corrections caused by inaccurate positioning in traditional construction. This saves a significant amount of time and further improves construction efficiency. Moreover, the buffer mechanism in the pole positioning device acts as a buffer during the installation of the tower frame structure, preventing damage to the tower structure and installation equipment caused by the impact force generated by the sudden stress or release of the slings. The buffer mechanism not only acts as a buffer when the drone places the tower frame structure onto the pole positioning device, but also enables the slow descent of the frame structure when two frame structures are connected and fixed in place, thus achieving more precise positioning. This invention reduces the time personnel spend working at heights by using drones for transportation and pole-mounting devices for installation assistance. This lowers the probability of falls due to human error or equipment malfunction, ensuring the safety of construction workers. Compared to traditional cableway, tracked vehicle, or helicopter transportation, drones have relatively lower purchase and maintenance costs. Modular assembly and drone transportation reduce the need for personnel on-site. This is especially beneficial in remote mountainous areas or areas with poor transportation where personnel travel and accommodation costs are high. By adopting the construction method of this invention, the number of construction workers can be effectively reduced, thereby lowering labor costs and achieving effective control of construction costs.
