For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] As mentioned in the background technology, during the hoisting process, the upper tower section shakes due to interference from factors such as wind. In order to achieve the positioning and docking of the bottom end of the upper tower section and the top end of the lower section, it is necessary to manually correct the falling direction of the upper tower section, but the correction effect is poor and there are great safety hazards.

[0048] To improve the above problems, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a tower hoisting and positioning device is provided, comprising a first deviation-correcting assembly 110, a second deviation-correcting assembly 120 and a third deviation-correcting assembly 170. The first deviation-correcting assembly 110 is suitable for being detachably mounted on the top of the lower cylinder section 200 and the bottom of the upper cylinder section 300 of the tower, and is used to correct the falling direction of the upper cylinder section 300. The second deviation-correcting assembly 120 is suitable for being detachably mounted on the top of the lower cylinder section 200, and is used to correct the falling direction of the upper cylinder section 300. The third deviation-correcting assembly 170 is suitable for being detachably mounted on the top of the lower cylinder section 200 and the bottom of the upper cylinder section 300, and is used to correct the falling direction of the upper cylinder section 300. When the upper cylinder section 300 is hoisted, during the falling process of the upper cylinder section 300, first, the second deviation-correcting assembly 120 works to correct the falling direction of the upper cylinder section 300, and can reduce the left and right shaking amplitude of the upper cylinder section 300. Then, the third deviation correction component 170 works again to correct the falling direction of the upper cylinder section 300 and reduce the swing amplitude of the upper cylinder section 300. When the distance between the bottom end of the upper cylinder section 300 and the top end of the lower cylinder section 200 gradually decreases to a certain distance, the first deviation correction component 110 participates in the deviation correction task, and cooperates with the second deviation correction component 120 and the third deviation correction component 170 to correct the falling direction of the upper cylinder section 300 and reduce the swing amplitude of the upper cylinder section 300. On the whole, it can assist or replace manual labor to correct the falling direction of the upper cylinder section 300, and the deviation correction effect is good, which greatly reduces safety hazards and reduces labor intensity and difficulty. Moreover, the second correcting assembly 120 and the third correcting assembly 170 are respectively connected to the cylinder sections in a detachable manner. After the lower cylinder section 200 and the upper cylinder section 300 are assembled, the second correcting assembly 120 and the third correcting assembly 170 can be removed, so that the second correcting assembly 120 and the third correcting assembly 170 can be recycled during the entire tower assembly process, thereby reducing the assembly cost.

[0049] It should be noted that, generally, a lower flange is provided on the inner side of the top end of the lower barrel section 200, and a plurality of upper mounting holes are evenly provided on the lower flange along the circumferential direction. An upper flange is provided on the inner side of the bottom end of the upper barrel section 300, and a plurality of lower mounting holes are evenly provided on the upper flange along the circumferential direction. The lower flange and the upper flange can be fixedly connected by bolts through the upper and lower mounting holes, so as to fix the lower barrel section 200 and the upper barrel section 300.

[0050] Specifically, in the exemplary embodiment, the first deviation correction component 110 includes a lower electromagnet 112 and an upper electromagnet 111. The lower electromagnet 112 is installed at the top of the lower barrel section 200. The upper electromagnet 111 is installed at the bottom of the upper barrel section 300, and the polarity of the bottom surface is opposite to the polarity of the top surface of the lower electromagnet 112. For the upper electromagnet 111 and the lower electromagnet 112, when powered, there is magnetic force; when powered off, the magnetic force disappears. When the distance between the bottom end of the upper barrel section 300 and the top end of the lower barrel section 200 gradually decreases to a certain distance, the upper electromagnet 111 and the lower electromagnet 112 are powered, and the falling direction of the upper barrel section 300 is corrected by means of magnetic force. When the bottom end of the upper barrel section 300 abuts against the top end of the lower barrel section 200, the upper electromagnet 111 and the lower electromagnet 112 lose power.

[0051] In some embodiments, there are multiple lower electromagnets 112, which are uniformly embedded in the lower flange along the circumference of the top of the lower barrel section 200. There are multiple upper electromagnets 111, which are uniformly embedded in the upper flange along the circumference of the bottom of the upper barrel section 300.

[0052] In other embodiments, the lower electromagnet 112 is a ring structure and is embedded in the lower flange. The upper electromagnet 111 is a ring structure and is embedded in the upper flange.

[0053] In some other embodiments, there are multiple lower electromagnets 112 and multiple upper electromagnets 111. Each lower electromagnet 112 includes a lower bolt and a coil wound around the lower bolt. Each upper electromagnet 111 includes an upper bolt and a coil wound around the upper bolt. An upper electromagnet 111 is inserted into one of each two adjacent upper mounting holes. A lower electromagnet 112 is inserted into one of each two adjacent lower mounting holes.

[0054] Preferably, there are multiple second deviation-correcting assemblies 120 suitable for being detachably mounted on multiple sides of the top of the lower cylinder section 200 to correct the falling direction of multiple sides of the upper cylinder section 300 and reduce the shaking amplitude of the upper tower section when it falls.

[0055] In some of these embodiments, reference Figure 1 and Figure 2Each second deviation-correcting assembly 120 includes a base 121 and a guide portion 122. The base 121 is detachably mounted on the inner wall of the lower barrel section 200 to support the guide portion 122. The guide portion 122 is swingably mounted on the top surface of the base 121. The swinging guide portion 122 can abut against the inner wall of the upper barrel section 300 to correct the falling direction of this side of the upper barrel section 300. After the upper barrel section 300 is assembled with the lower barrel section 200, the swinging guide portion 122 can be separated from the inner wall of the upper barrel section 300. Each second deviation-correcting assembly 120 also includes a first support rod 123, a second support rod 124 and an electric push rod 125. One end of the first support rod 123 is rotatably connected to the top surface of the base 121, and the other end is rotatably connected to the bottom surface of the guide portion 122. One end of the second support rod 124 is rotatably connected to the top surface of the base 121, and the other end is rotatably connected to the bottom surface of the guide portion 122. The cylinder of the electric push rod 125 is rotatably connected to the top surface of the base 121, and the telescopic rod is rotatably connected to the middle part of the first support rod 123. The telescopic rod of the electric push rod 125 can be extended or retracted to make the first support rod 123 and the second support rod 124 move, thereby making the guide portion 122 abut against the inner wall of the upper cylinder section 300 or separate from the inner wall of the upper cylinder section 300. The base 121 includes a base plate 1211 and a support beam 1212. The top surface of the base plate 1211 is equipped with a swingable guide portion 122, a first support rod 123, a second support rod 124 and an electric push rod 125. One side of the base plate 1211 is detachably connected to the inner wall of the lower barrel section 200 by screws or by a connecting plate. The axis of the support beam 1212 is tilted, and the higher end is detachably connected to the bottom surface of the base plate 1211, and the lower end is detachably connected to the inner wall of the lower barrel section 200, so that the base 121 is detachably connected to the lower barrel section 200, and then each second deviation correction component 120 is detachably connected to the inner wall of the lower barrel section 200, so as to facilitate the installation, use and disassembly of the second deviation correction component 120. The support beam 1212 can improve the stability of the position of the base plate 1211, and when the second deviation correction component 120 participates in the deviation correction task, it is not easy to fall over, thereby improving the stability of the deviation correction work. Each guide part 122 includes a swing block 1221, two buffer springs 1222 and a pressing block 1223. The swing block 1221 is swingably mounted on the top surface of the base 121, and the bottom surface is rotatably connected to the other end of the first support rod 123 and the other end of the second support rod 124. The axes of the two buffer springs 1222 are arranged in parallel, and one end is fixedly connected to one side of the swing block 1221. One side of the pressing block 1223 is fixedly connected to the other end of the two buffer springs 1222, and the other side is projected from top to bottom into an arc structure. The arc structure enables the pressing block 1223 to be in close contact with the inner wall of the upper barrel section 300, thereby increasing the contact area and improving the deviation correction effect.The material of the pressing block 1223 is rubber, which can effectively reduce the wear degree of the pressing block 1223 when it contacts the upper barrel section 300. The buffer spring 1222 can further reduce the shaking amplitude of the upper barrel section 300.

[0056] In other embodiments, referring to Figure 3 and Figure 4Each second deviation-correcting assembly 120 includes a base 121 and a guide portion 122. The base 121 is detachably mounted on the inner wall of the lower barrel section 200 to support the guide portion 122. The guide portion 122 is swingably mounted on the top surface of the base 121. The swinging guide portion 122 can abut against the inner wall of the upper barrel section 300 to correct the falling direction of this side of the upper barrel section 300. After the upper barrel section 300 is assembled with the lower barrel section 200, the swinging guide portion 122 can be separated from the inner wall of the upper barrel section 300. Each second deviation-correcting assembly 120 also includes a first support rod 123, a second support rod 124 and an electric push rod 125. One end of the first support rod 123 is rotatably connected to the top surface of the base 121, and the other end is rotatably connected to the bottom surface of the guide portion 122. One end of the second support rod 124 is rotatably connected to the top surface of the base 121, and the other end is rotatably connected to the bottom surface of the guide portion 122. The cylinder of the electric push rod 125 is rotatably connected to the top surface of the base 121, and the telescopic rod is rotatably connected to the middle part of the first support rod 123. The telescopic rod of the electric push rod 125 can be extended or retracted to make the first support rod 123 and the second support rod 124 move, thereby making the guide portion 122 abut against the inner wall of the upper cylinder section 300 or separate from the inner wall of the upper cylinder section 300. The base 121 includes a base plate 1211, and the top surface of the base plate 1211 is mounted with a swingable guide portion 122, a first support rod 123, a second support rod 124 and an electric push rod 125. Each guide portion 122 includes a swing block 1221. The swing block 1221 is swingably mounted on the top surface of the base 121, and the bottom surface is rotatably connected to the other end of the first support rod 123 and the other end of the second support rod 124 respectively. The tower hoisting positioning device also includes a guide rail 130 of a circular ring structure, a drive motor 140, a driving gear 150 and a driven ring gear 160. The outer wall of the guide rail 130 is detachably connected to the inner wall of the top of the lower barrel section 200. One side of the base plate 1211 of the base 121 of each second deviation correction component 120 is slidably mounted on the guide rail 130. Each base 121 can slide along the guide rail 130. The drive motor 140 is detachably mounted on the floor of the lower barrel section 200, and the output shaft is arranged upward. The driving gear 150 is sleeved on the output shaft of the drive motor 140. The outer wall of the driven gear ring 160 is detachably connected to the other side of the base plate 1211 of the base 121 of each second deviation-correcting assembly 120, and the inner wall is meshedly connected to the side wall of the driving gear 150. The driving motor 140 can drive the driving gear 150 to rotate, thereby driving the driven gear ring 160 to rotate, thereby driving each base 121 and each second deviation-correcting assembly 120 to rotate along the circumferential direction of the guide rail 130. Before the bottom end of the upper barrel section 300 abuts against the top end of the lower barrel section 200, the upper mounting hole and the lower mounting hole may be misaligned up and down.Each second deviation-correcting assembly 120 rotates along the circumference of the guide rail 130 , thereby driving the upper barrel section 300 to rotate around its own axis, so that the upper mounting hole and the lower mounting hole are vertically aligned, thereby facilitating the assembly of the upper barrel section 300 and the lower barrel section 200 .

[0057] Preferably, the guide rail 130 is formed by splicing a plurality of arc-shaped rail segments, so as to facilitate the disassembly and assembly of the guide rail 130 and facilitate the position transfer of the guide rail 130 .

[0058] Preferably, the driven gear ring 160 is formed by splicing a plurality of rack segments of arc-shaped structures, so as to facilitate the disassembly and assembly of the driven gear ring 160 and facilitate the position transfer of the driven gear ring 160 .

[0059] Specifically, in the exemplary embodiment, the third deviation correction assembly 170 includes two rope transmitters 171 and two rope head receivers 172. The two rope transmitters 171 are detachably mounted on opposite sides of the upper flange at the bottom of the upper barrel section 300, and can respectively launch ropes. The two rope head receivers 172 are detachably mounted on opposite sides of the lower flange at the top of the lower barrel section 200. The two rope head receivers 172 correspond to the two rope transmitters 171 one by one, and can respectively receive the rope heads of the ropes launched by the corresponding rope transmitters 171, and reel in the ropes. When the upper mounting hole and the lower mounting hole are aligned vertically, the two rope transmitters 171 respectively launch ropes. The two rope head receivers 172 respectively receive the rope heads of the ropes launched by the corresponding rope transmitters 171, and reel in the ropes to pull the upper barrel section 300 to fall. After the upper and lower barrel sections are assembled, the two rope head receivers 172 release the ropes respectively.

[0060] The working process and principle of the tower hoisting positioning device are as follows:

[0061] First, the guide parts 122 of the second deviation-correcting assemblies 120 swing to respectively contact the inner walls of multiple sides of the upper barrel section 300 to correct the falling direction of the corresponding sides of the upper barrel section 300. Then, the driving motor 140 drives the driving gear 150 and the driven gear ring 160 to rotate, thereby driving the guide parts 122 of each second deviation-correcting assembly 120 to rotate along the circumference of the guide rail 130, and the guide parts 122 of the second deviation-correcting assemblies 120 drive the upper barrel section 300 to rotate around its own axis so that the upper mounting hole and the lower mounting hole are aligned vertically. When the upper mounting hole and the lower mounting hole are aligned vertically, the two rope launchers 171 respectively launch ropes. The two rope head receivers 172 respectively receive the rope heads of the ropes launched by the corresponding rope launchers 171, and reel in the ropes to pull the upper barrel section 300 to fall. When the distance between the bottom end of the upper barrel section 300 and the top end of the lower barrel section 200 gradually decreases to a certain distance, the upper electromagnet 111 and the lower electromagnet 112 are powered to correct the falling direction of the upper barrel section 300 with the help of magnetic force. When the bottom end of the upper barrel section 300 abuts against the top end of the lower barrel section 200, the upper electromagnet 111 and the lower electromagnet 112 lose power. At the same time, the guide parts 122 of the multiple second deviation correction components 120 swing to separate from the inner wall of the upper barrel section 300 respectively. The driving gear 150 and the driven gear ring 160 also stop rotating. The two rope head receivers 172 release the ropes respectively.
