DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0033] Example 1:

[0034] Reference Figure 3-Figure 5 , a transmission tower that is easy to install, includes a first tower body 1 with an isosceles trapezoidal cross-section, and also includes: a second tower body 2 with an isosceles trapezoidal cross-section, which is sleeved on the upper end of the first tower body 1, wherein the upper end of the second tower body 2 is sleeved on a third tower body 3 with an isosceles trapezoidal cross-section, the side walls of the first tower body 1, the second tower body 2 and the third tower body 3 are parallel to each other, and the lower end of the second tower body 2 and the upper end of the first tower body 1, as well as the lower end of the third tower body 3 and the upper end of the second tower body 2 are connected by a snap mechanism; two pairs of cantilevers 4 are fixedly connected to the outer wall of the third tower body 3, wherein the upper ends of the second tower body 2 and the first tower body 1 are both provided with slots 12, and the outer walls of the first tower body 1 and the second tower body 2 are both fixedly connected to metal rails 5 coplanar with their outer walls; two groups of supporting beams 10 are respectively fixedly connected to the lower ends of the first tower body 1 and the second tower body 2, wherein the upper ends of the two groups of supporting beams 10 are both fixedly connected to positioning tubes 11.

[0035] During assembly, the third tower body 3 is placed inside the second tower body 2, and the lower end of the third tower body 3 is clamped in the positioning tube 11 of the supporting beam 10. Then, the second tower body 2 is placed inside the first tower body 1, and the lower end of the third tower body 3 is clamped in the positioning tube 11. In this way, the entire transmission tower can be condensed into a whole, which is convenient for later transportation and installation. During installation, first fix the lower end of the first tower body 1 to the ground, and then use the lifting equipment to lift the second tower body 2 upward to the upper port of the first tower body 1, and then lift the third tower body 3 to the upper port of the second tower body 2. The snap mechanism can automatically fix the second tower body 2 to the upper port of the first tower body 1, and the third tower body 3 will be automatically fixed to the upper port of the second tower body 2. The installation efficiency of the entire transmission tower is greatly improved.

[0036] In practice, the transmission tower may further include a fourth tower body on the upper end of the third tower body 3 and a fifth tower body on the upper end of the fourth tower body, and so on, as needed.

[0037] Example 2:

[0038] Reference Figure 3 、 Figure 4 、 Figure 6 as well as Figure 8, which is basically the same as Example 1, and further discloses a specific implementation scheme of the snap mechanism.

[0039] The snap-fit ​​mechanism includes a slide groove 6 arranged on the inner wall of the upper end of the first tower body 1 and the second tower body 2, and a wedge block 7 is slidably connected in both sets of slide grooves 6, wherein the wedge block 7 is elastically connected to the inner wall of the slide groove 6 by a tightening spring 8, and the lower ends of the second tower body 2 and the first tower body 1 are provided with a snap-fit ​​groove 9 that cooperates with the wedge block 7.

[0040] During installation, the second tower body 2 is lifted upward, and the second tower body 2 will drive the third tower body 3 inside it to move upward synchronously. When the outer wall of the lower end of the second tower body 2 moves to the inner wall of the upper port of the first tower body 1, the outer wall of the second tower body 2 will push the wedge block 7 on the inner wall of the first tower body 1 into the slide groove 6. When the slot 9 on the outer wall of the lower end of the second tower body 2 is aligned with the wedge block 7, the wedge block 7 will push its end into the slot 9 under the action of the tightening spring 8. At this time, the pre-fixing work of the second tower body 2 can be completed, and then the screws fixing the second tower body 2 can be manually tightened. The transmission tower can be fixed efficiently and conveniently, and then the third tower body 3 can be fixed in the same way.

[0041] Example 3:

[0042] Reference Figures 1-8 , a transmission tower that is easy to install, includes a plate-shaped remote-controlled vehicle 13 with wheels 14, and also includes a circular electromagnet fixedly installed in the wheel 14; a reel 23 is rotatably connected to the top of the remote-controlled vehicle 13 through a rotating shaft 22, wherein a pull belt 28 is fixedly wound around the reel 23, and a hook 29 is fixedly installed at the end of the pull belt 28, and a driving part for driving the reel 23 to rotate is provided on the outer wall of the remote-controlled vehicle 13; two sliding holes 21 are both provided on the side walls of the remote-controlled vehicle 13, wherein a horizontal plate 19 is slidably connected in the two sliding holes 21, and a downward-inclined hook plate 40 is fixedly connected to one end of the two horizontal plates 19 near the wheel 14, and a telescopic part for driving the horizontal plate 19 to move horizontally is provided on the remote-controlled vehicle 13;

[0043] During installation, first fix the lower end of the first tower body 1 to the ground, then fit the wheels 14 of the remote control car 13 to the metal track 5 of the first tower body 1. At this time, the electromagnet in the wheel 14 is energized, and the wheel 14 can be adsorbed on the outer wall of the metal track 5. Then, the two remote control cars 13 located on both sides of the first tower body 1 are moved synchronously along the metal track 5 to the top of the first tower body 1 (as shown in FIG. Figure 5As shown), the two horizontal plates 19 and the hook plates 40 are driven to move synchronously by the telescopic portion, so that the two hook plates 40 are just moved to the upper ends of the two slots 12 at this time, and then the remote control car 13 is moved downward, so that the two hook plates 40 driven by the remote control car 13 are stuck in the slots 12, and the fixing work of the remote control car 13 can be completed quickly and conveniently, thereby facilitating the subsequent installation of the transmission tower. Then, the reel 23 is driven to rotate by the driving portion, and the reel 23 will start to unload the pull belt 28 of the outer wall, and the hook 29 will fall to the inner bottom of the first tower body 1. When the hook 29 When reaching the bottom of the first tower body 1, the hooks 29 on both sides are manually hooked onto the beams on both sides of the bottom of the first tower body 1, and then the drive motor 24 drives the reel 23 to reverse, and the two reels 23 will begin to wind the pull belt 28. The two sets of pull belts 28 will lift the second tower body 2 upward through the two hooks 29, and the second tower body 2 will drive the third tower body 3 inside it to move upward synchronously, so that the lifting work of the second tower body 2 and the third tower body 3 can be achieved without the use of cranes and helicopters, the installation level is greatly reduced, and the installation process is not easily affected by the environment.

[0044] In practice, in order to ensure the movement stability and accuracy of the remote control car 13, more than three sets of wheels 14 can be installed on the remote control car 13, and a camera can be installed to remotely monitor the real-time picture.

[0045] Furthermore, a strip groove is provided in the metal track 5, and a permanent magnet is fixedly connected to the strip groove. When the remote control car 13 rolls in the metal track 5 through the wheels 14, the wheels 14 can be stuck in the strip groove, so that the remote control car 13 is well guided, and the permanent magnet in the strip groove can make the wheels 14 more firmly adsorbed on the metal track 5.

[0046] Example 4:

[0047] Reference Figure 1-Figure 2 as well as Figure 5-Figure 7 , which is basically the same as Example 3, further discloses a specific implementation plan of the driving unit.

[0048] The driving part includes a bracket 16 fixedly connected to the outer wall of the remote control car 13, and a transmission shaft 25 is rotatably connected to the bracket 16. One end of the transmission shaft 25 is connected to the rotating shaft 22 through a worm gear 26. A driving motor 24 is also fixedly mounted on the bracket 16, and the output shaft of the driving motor 24 is connected to the transmission shaft 25 through two meshing gears 27.

[0049] When it is necessary to drive the reel 23 to rotate, the drive motor 24 is started. The drive motor 24 drives the transmission shaft 25 to rotate through two meshing gears 27. The transmission shaft 25 drives the reel 23 to rotate through the worm gear 26. The reel 23 will start to unload the drawstring 28 on the outer wall, and the hook 29 will fall to the inner bottom of the first tower body 1. When the hook 29 reaches the bottom of the first tower body 1, the hooks 29 on both sides are manually hooked onto the beams on both sides of the bottom of the first tower body 1, and then the drive motor 24 drives the reel 23 to reverse. The two reels 23 will start to wind the drawstring 28, and the two sets of drawstrings 28 will lift the second tower body 2 upward through the two hooks 29, and the second tower body 2 will drive the third tower body 3 inside it to move upward synchronously.

[0050] Example 5:

[0051] Reference Figure 1-Figure 2 as well as Figure 5-Figure 7 , which is basically the same as Example 4, and further discloses a specific implementation plan of the telescopic part.

[0052] The telescopic portion includes an electric telescopic rod 17 fixedly mounted on the bracket 16, wherein the telescopic end of the electric telescopic rod 17 is fixedly connected to a limit plate 18 parallel to the outer wall of the remote control car 13, and two horizontal plates 19 are fixedly connected to the side walls of the limit plate 18;

[0053] When the remote control car 13 needs to be fixed to the second tower body 2 and the third tower body 3, the electric telescopic rod 17 drives the limit plate 18 to press against the outer wall of the remote control car 13. The limit plate 18 will then drive the two cross plates 19 and the hook plate 40 to move synchronously, so that the two hook plates 40 will just move to the upper ends of the two slots 12. Then the remote control car 13 is moved downward, so that the remote control car 13 drives the two hook plates 40 to be stuck in the slots 12. The fixing work of the remote control car 13 can be completed quickly and conveniently, thereby facilitating the subsequent installation of the transmission tower.

[0054] Furthermore, an air blowing nozzle 36 is provided at the end of the hook plate 40, and a device groove 37 is provided on the remote control car 13. An air supply portion for supplying air to the air blowing nozzle 36 is provided in the device groove 37. The air supply portion includes an elastic airbag 38 fixedly installed in the device groove 37. The telescopic end of the elastic airbag 38 is pressed against the outer wall of the limit plate 18. The elastic airbag 38 is fixedly connected to the air intake pipe 15 and the pressing wheel 32 connected thereto. A one-way valve is fixedly installed in both the air intake pipe 15 and the exhaust pipe 39. The end of the exhaust pipe 39 is fixedly connected to the input end of the air blowing nozzle 36.

[0055] When the limit plate 18 approaches the outer wall of the remote control car 13, the limit plate 18 will press the elastic airbag 38, and the elastic airbag 38 will discharge the air inside it through the exhaust pipe 39. The blowing nozzle 36 will blow the air into the slot 12, thereby blowing out the dust in the slot 12, preventing the second tower body 2 and the first tower body 1 from being contaminated by dust in the slot 12 during transportation, thereby ensuring installation efficiency. When the limit plate 18 moves in the opposite direction, the elastic airbag 38 will elastically reset and inhale outside air through the suction pipe 15.

[0056] Example 6:

[0057] Refer to the figure Figure 1-Figure 2 as well as Figure 5-Figure 8 , which is basically the same as Example 5, and further, a specific implementation plan for preventing the second tower body 2 and the third tower body 3 from shaking is specifically added.

[0058] A threaded rod 31 is rotatably connected to the bracket 16, and an internally threaded tube 30 is threadedly connected to the outer wall of the threaded rod 31. A guide hole is provided on the outer wall of the remote control car 13, and the internally threaded tube 30 is slidably connected to the guide hole. A clamping wheel 32 is installed on the end of the internally threaded tube 30 near the wheel 14. The threaded rod 31 is connected to the drive shaft 25 through a chain drive 33;

[0059] When the drive shaft 25 drives the hook 29 to move upward, that is, when the second tower body 2 is lifted upward, the drive shaft 25 drives the threaded rod 31 to reverse, and at this time the locking wheel 32 will slowly move in the direction away from the second tower body 2. Since the outer wall of the second tower body 2 is inclined, the locking wheel 32 will always be pressed against both sides of the second tower body 2 when the second tower body 2 is lifted upward, thereby preventing the upper end of the second tower body 2 from swaying left and right due to natural wind, thereby improving the safety and installation efficiency during the installation of the power tower.

[0060] Furthermore, a buffer hole 34 is provided at the end of the threaded rod 31, and a buffer column 35 is slidably connected to the buffer hole 34. The buffer column 35 and the inner wall of the buffer hole 34 are elastically connected by a buffer spring 20, and the clamping wheel 32 is rotatably mounted on the buffer column 35; when the second tower body 2 slides left and right due to natural wind, the second tower body 2 sliding left and right can drive the buffer column 35 to slide back and forth in the buffer hole 34. At this time, the buffer spring 20 can offset the impact force of the second tower body 2 on the clamping wheel 32, thereby providing buffering protection for the clamping wheel 32 and the second tower body 2, and reducing the chance of damage to the second tower body 2.

[0061] During assembly, the transmission tower, which is easy to install, is assembled by placing the third tower body 3 inside the second tower body 2, and allowing the lower end of the third tower body 3 to be clamped in the positioning tube 11 of the supporting beam 10. Then, the second tower body 2 is placed inside the first tower body 1, and the lower end of the third tower body 3 is clamped in the positioning tube 11. In this way, the entire transmission tower can be condensed into a whole, thereby facilitating subsequent transportation and installation.

[0062] During installation, first fix the lower end of the first tower body 1 to the ground, then fit the wheels 14 of the remote control car 13 to the metal track 5 of the first tower body 1. At this time, the electromagnet in the wheel 14 is energized, and the wheel 14 can be adsorbed on the outer wall of the metal track 5. Then, the two remote control cars 13 located on both sides of the first tower body 1 are moved synchronously along the metal track 5 to the top of the first tower body 1 (as shown in FIG. Figure 5 As shown), the electric telescopic rod 17 then drives the limiting plate 18 to press against the outer wall of the remote control car 13. The limiting plate 18 then drives the two horizontal plates 19 and the hook plate 40 to move synchronously, so that the two hook plates 40 are just moved to the upper ends of the two slots 12. Then, the remote control car 13 is moved downward, so that the remote control car 13 drives the two hook plates 40 to be stuck in the slots 12. This can quickly and conveniently complete the fixing work of the remote control car 13, thereby facilitating the subsequent installation of the transmission tower.

[0063] After the remote control car 13 is fixed, the drive motor 24 is started. The drive motor 24 drives the transmission shaft 25 to rotate through two meshing gears 27. The transmission shaft 25 drives the reel 23 to rotate through the worm gear 26. The reel 23 will start to unload the drawstring 28 on the outer wall, and the hook 29 will fall to the inner bottom of the first tower body 1. When the hook 29 reaches the bottom of the first tower body 1, the hooks 29 on both sides are manually hooked to the beams on both sides of the bottom of the first tower body 1, and then the drive motor 24 drives the reel 23 to reverse, and the two reels 23 will start to wind the drawstring 28. The two sets of drawstrings 28 will pass through the two hooks. 29 Lift the second tower body 2 upward, and the second tower body 2 will drive the third tower body 3 inside it upward synchronously. When the outer wall of the lower end of the second tower body 2 moves to the inner wall of the upper end of the first tower body 1, the outer wall of the second tower body 2 will push the wedge block 7 on the inner wall of the first tower body 1 into the slide groove 6. When the slot 9 on the outer wall of the lower end of the second tower body 2 is aligned with the wedge block 7, the wedge block 7 will push its end into the slot 9 under the action of the tightening spring 8. At this time, the pre-fixing work of the second tower body 2 can be completed. Then, the screws fixing the second tower body 2 can be manually tightened, and the transmission tower can be fixed efficiently and conveniently.

[0064] After the installation of the second tower body 2 is completed, the hook 29 is removed from the crossbeam of the second tower body 2, and the remote control car 13 is moved to the upper outer wall of the second tower body 2. Then, the third tower body 3 is fixed to the top of the second tower body 2 using the same principle as above, and the fixing of the third tower body 3 is completed. Then, the lighter cantilever 4 is manually fixed to the outer wall of the third tower body 3. The entire fixing process does not require the use of cranes and helicopters, which greatly reduces the installation cost and greatly improves the installation efficiency. Moreover, since the second tower body 2 and the third tower body 3 are both located inside the first tower body 1, it is difficult for natural wind to blow the second tower body 2 and the third tower body 3 crooked, which indirectly improves the installation efficiency and safety of the transmission tower.

[0065] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
