Description

Technical Field

[0001] The invention relates to the technical field of steel pipe tower accessories, in particular to a bottom supporting structure of a steel pipe tower. Background Art

[0002] As a common supporting structure, steel pipe tower is widely used in the fields of power transmission, communication base stations, etc., among which both power transmission and communication base stations are in demand in coastal areas. Steel pipe tower is composed of steel pipes and other components. It can meet the distance requirements between the conductor and the ground and the ground objects, and can withstand the load of the conductor, lightning conductor and its own load as well as external loads. It has been widely used. In the existing steel pipe tower structure, the bottom is directly fixed to the underground structure with expansion screws. This structural design is easy to cause the bottom of the steel pipe tower to loosen, and when used in coastal areas, the connection is prone to rust. The fixing method of expansion screws is more troublesome to maintain, and the safety risks also increase with the increase of service time.

[0003] For example, the bottom support structure of a steel pipe tower disclosed in Publication No. CN220580676U does not require the use of expansion screws for fixing, but still requires the use of bolts. Over time, they are not only prone to rust and loosening, but may also cause thread slippage, making maintenance more difficult. The bottom support structure of a steel pipe tower disclosed in Publication No. CN113863764A, although it not only uses bolts for fixing, but also has a method of fixing by fitting between irregular grooves, requires the use of a large threaded sleeve, which is still prone to rust and thread slippage.

[0004] Therefore, a bottom support structure of a steel tube tower is proposed. Summary of the Invention

[0055] The present invention provides a bottom support structure for a steel pipe tower. Compared with the prior art, it has the following advantages:

[0056] (1) The bottom support structure of the steel pipe tower is used to limit the steel pipe tower body by turning over and fixing in an annular manner, so that the steel pipe tower can adjust its angle according to the terrain or specific needs during installation, ensuring its verticality and overall stability, further strengthening this stability, and preventing the tower body from moving or tilting unnecessarily due to external factors. When the steel pipe tower needs to be repaired, the detachable feature of the annular fixation provides great convenience. Compared with the traditional fixing method, it can be disassembled and reinstalled more quickly, reducing downtime and reducing maintenance costs. At the same time, the addition of adsorption connection can significantly increase the friction and contact area between the steel pipe tower and the clamp, making the connection more firm and reliable, especially in coastal areas with high humidity, it can effectively prevent the intrusion of rain and seawater, prevent the connection from being rusted, and increase the service life of the steel pipe tower body.

[0057] (2) The bottom support structure of the steel pipe tower can be cleaned and repaired through remote control maintenance components, which can greatly reduce the risk of personal injury. Once the anti-corrosion layer is detected to have signs of peeling, the maintenance components can be immediately started for processing without waiting for manpower to be arranged. This helps prevent further spread of corrosion and extend the service life of the steel pipe tower. Although the initial investment may be high, in the long run, it reduces the labor cost of maintenance and the large-scale repair costs caused by corrosion, improves maintenance efficiency and safety, and can effectively prevent the development of corrosion problems and protect the safe and stable operation of infrastructure.

[0058] (3) The bottom support structure of the steel pipe tower integrates the cleaning and re-spraying functions into one system, realizing one-stop treatment of damage to the anti-corrosion layer, simplifying the maintenance process, reducing repeated positioning and preparation time, and greatly improving the overall efficiency of the maintenance operation. Re-spraying the anti-corrosion layer in time after cleaning the debris can effectively prevent further corrosion of the exposed metal surface, protect the steel pipe tower structure from erosion by environmental factors, and extend its service life. Combined with the remote control system, the operator can monitor the entire maintenance process without being on site, and adjust the operating parameters according to the actual situation to ensure the quality of maintenance.

[0059] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0073] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0074] See also Figures 1 to 12 , the present invention provides the following technical solutions:

[0075] Example 1: A bottom support structure of a steel pipe tower, comprising a steel pipe tower body 1 to be installed and a bottom plate 11 for supporting the steel pipe tower body 1. A fixing assembly for supporting the steel pipe tower body 1 is provided within the bottom plate 11. The fixing assembly includes: a movable shaft 2, a support rod 21, a fixing plate 25, a piston 26, a sliding rod 27, a power plate 28, a threaded rod 29, a positioning plate 210, a guide column 211, and a spring 212.

[0076] Both ends of the movable shaft 2 are movably mounted in the base plate 11 through bearings;

[0077] The support rod 21 is fixedly sleeved outside the movable shaft 2. The support rod 21 is rotated with the movable shaft 2 as the axis under the squeezing of the steel pipe tower body 1;

[0078] The side wall of the fixing plate 25 is slidably abutted against the outside of the steel pipe tower body 1, and the fixing plate 25 supports and limits the steel pipe tower body 1;

[0079] The side wall of the piston 26 is slidably mounted in the fixed plate 25. A seal is provided between the piston 26 and the fixed plate 25. Under the action of an external force, the piston 26 creates a negative pressure between the fixed plate 25 and the steel pipe tower body 1, thereby enhancing the support and limiting degree.

[0080] One end of the sliding rod 27 is slidably inserted into the fixed plate 25 , and one end of the sliding rod 27 located in the fixed plate 25 is fixedly mounted on the side wall of the piston 26 , so that the sliding rod 27 provides support for the piston 26 ;

[0081] The side wall of the power plate 28 is fixedly mounted on the end of the sliding rod 27 away from the piston 26. The power plate 28 is used to transmit the power required for the movement of the piston 26.

[0082] One end of the threaded rod 29 is threadedly inserted into the power plate 28, and the other end of the threaded rod 29 is movably mounted on the side wall of the vertical plate through a bearing. The bottom of the vertical plate is fixedly mounted on the top of the fixed plate 25;

[0083] The side wall of the positioning plate 210 abuts against the threaded rod 29, and the positioning plate 210 is used to limit the rotation of the threaded rod 29;

[0084] One end of the guide post 211 is fixedly mounted on the side wall of the power plate 28, and the other end of the guide post 211 slides out of the positioning plate 210. The guide post 211 is used to limit the moving direction of the positioning plate 210.

[0085] One end of spring 1 212 is fixedly mounted on the side wall of the power plate 28 , and the other end of spring 1 212 is fixedly mounted on the side wall of the positioning plate 210 . Spring 1 212 provides elastic force for resetting the positioning plate 210 .

[0086] When in use, the steel pipe tower body 1 is hoisted to the bottom plate 11. During the process of inserting the steel pipe tower body 1 into the bottom plate 11 from above, the bottom of the steel pipe tower body 1 will slide and abut against the support rod 21, thereby applying a force to the support rod 21. At the same time, the support rod 21 is provided with a supporting force through the movable shaft 2, so that the support rod 21 can be turned around the movable shaft 2 as the axis. The guide rod 24 is driven to move synchronously by the support rod 21, and the guide rod 24 drives the fixed plate 25 to move, so that the fixed plates 25 on both sides of the steel pipe tower body 1 can be turned synchronously, thereby limiting the position of the steel pipe tower body 1 and preventing the steel pipe tower body 1 from tilting during the installation process.

[0087] After the fixing plate 25 is in close contact with the steel pipe tower body 1, the positioning plate 210 is pulled to the side away from the steel pipe tower body 1, and the positioning plate 210 and the guide column 211 are slidably matched, so that the positioning plate 210 can only move linearly along the guide column 211 under the action of external force, thereby causing the positioning plate 210 to move out of the threaded rod 29. At this time, the threaded rod 29 can be rotated, and the threaded rod 29 is provided with a supporting force by the vertical plate. The threaded rod 29 and the power plate 28 are threadedly matched, and the power plate 28 drives the sliding rod 27 to move synchronously. The sliding rod 27 and the fixing plate 25 are slidably matched, so that the sliding rod 27 can move linearly along the fixing plate 25 under the drive of the threaded rod 29 and the power plate 28. During the movement of the sliding rod 27, the piston 26 is simultaneously driven to move, so that the piston 26 sucks out the air between the fixing plate 25 and the steel pipe tower body 1, thereby generating negative pressure, so that the steel pipe tower body 1 can be firmly connected to the fixing plate 25.

[0088] Then, the positioning plate 210 is released, and the positioning plate 210 moves into the threaded rod 29 under the action of spring 1 212, thereby limiting the threaded rod 29 and preventing the threaded rod 29 from rotating, so that the piston 26 remains in its position, allowing the steel pipe tower body 1 to maintain a stable connection with the fixed plate 25.

[0089] Embodiment 2: This embodiment differs from the embodiment 1 in that: a maintenance component for extending the service life is provided in the base plate 11, and the maintenance component includes: a moving electromagnet 22, a moving magnet 23, and a guide rod 24;

[0090] The movable electromagnet 22 is fixed in the support rod 21;

[0091] The movable magnet 23 is slidably mounted in the support rod 21 and is magnetically coupled with the movable electromagnet 22;

[0092] A guide rod 24, one end of which is slidably inserted into the support rod 21 and the other end of which is fixed to the bottom of the fixing plate 25;

[0093] The maintenance assembly also includes: a support plate 3, a compensation push rod 31, a limit rod 32, a connecting plate 1 33, a mounting plate 34, a maintenance plate 35, a scraping electromagnet 36, a scraping magnet 37, a spring 2 38, a fixing rod 39, and a scraping plate 310;

[0094] The bottom of the support plate 3 is fixedly mounted on the top of the base plate 11;

[0095] One end of the compensation push rod 31 is fixedly mounted on the side wall of the support plate 3, and the compensation push rod 31 is used to drive the maintenance component to move;

[0096] One end of the limiting rod 32 is fixedly mounted on the side wall of the support plate 3;

[0097] The side wall of the connecting plate 1 33 is fixedly mounted on the output end of the compensating push rod 31 , and the connecting plate 1 33 is slidably sleeved outside the limiting rod 32 , which is used to limit the moving direction of the connecting plate 1 33 ;

[0098] One end of the mounting plate 34 is fixedly mounted on the side wall of the connecting plate 1 33, and the other end of the mounting plate 34 is fixedly mounted on the side wall of the maintenance plate 35. The mounting plate 34 is used to provide support for the maintenance plate 35.

[0099] The maintenance plate 35 is located above the fixing plate 25 and is used to support the steel pipe tower body 1 when removing anti-corrosion layer debris;

[0100] The bottom of the scraping electromagnet 36 is fixedly mounted on the top of the maintenance plate 35;

[0101] The scraping magnet 37 is located above the scraping electromagnet 36, and the scraping magnet 37 and the scraping electromagnet 36 are magnetically matched;

[0102] One end of the second spring 38 is fixedly mounted on the top of the maintenance plate 35, and the other end of the second spring 38 is fixedly mounted on the bottom of the scraping magnet 37;

[0103] One end of the fixing rod 39 is fixedly mounted on the bottom of the scraping magnet 37, and the other end of the fixing rod 39 is slidably inserted into the maintenance plate 35. The bottom of the fixing rod 39 is fixedly mounted on the top of the scraping plate 310 to provide support for the scraping plate 310.

[0104] The scraping plate 310 is located inside the maintenance plate 35 , and the scraping plate 310 scrapes off the anti-corrosion layer debris on the surface of the steel pipe tower body 1 under the action of external force.

[0105] During use, when the anti-corrosion layer at the connection of the steel pipe tower body 1 falls off after being used for a period of time, the remote control center controls the compensation push rod 31 to start, and the compensation push rod 31 drives the connecting plate 1 33 to move, the connecting plate 1 33 drives the installation plate 34 to move, and the installation plate 34 drives the maintenance plate 35 to move, so that the maintenance plate 35 abuts against the side wall of the steel pipe tower body 1, thereby supporting the steel pipe tower body 1;

[0106] Then, the remote control center controls the moving electromagnet 22 to be energized, causing the magnetic attraction between the moving electromagnet 22 and the moving magnet 23, causing the moving magnet 23 to slide toward the side where the moving electromagnet 22 is located. The moving magnet 23 drives the guide rod 24 to move synchronously, causing the guide rod 24 to drive the fixed plate 25 to move, causing the fixed plate 25 to move a short distance away from the steel pipe tower body 1;

[0107] At this time, the scraping electromagnet 36 is energized through the remote control center, so that the magnetism of the scraping electromagnet 36 is first attracted to the scraping magnet 37, so that the scraping magnet 37 drives the fixing rod 39 to move in the vertical direction under the action of the magnetic attraction force, so that the fixing rod 39 drives the scraping plate 310 to move vertically, thereby cleaning the area on the steel pipe tower body 1 that is in contact with the fixing plate 25 and where the anti-corrosion layer has fallen off, and causing the debris that is still partially adhered near the fallen anti-corrosion layer to fall off;

[0108] Then the magnetism of the scraping electromagnet 36 changes to mutual repulsion with the magnetism of the scraping magnet 37, so that the scraping magnet 37 is reset upward under the combined action of the repulsive force and the elastic force of the spring 2 38, so that the fixed rod 39 drives the scraping plate 310 to reset upward until it leaves the area where the anti-corrosion layer falls off, and then the magnetism of the scraping electromagnet 36 is changed again, and this is repeated 5-8 times, and then the anti-corrosion layer spraying operation is carried out again. After the spraying operation is completed, the magnetic repulsion between the moving electromagnet 22 and the moving magnet 23 is controlled to make the fixed plate 25 support and limit the steel pipe tower body 1 again.

[0109] Embodiment 3: This embodiment differs from the embodiment 2 in that the technical solution includes: an auxiliary component for spraying the anti-corrosion coating is provided in the bottom plate 11, and the auxiliary component includes: a storage box 4, a feeding pipe 41, a feeding box 42, an upper slide bar 43, a lower slide bar 44, a moving rod 45, a spring 451, a guide plate 46, and a driven rod 47;

[0110] The bottom of the storage box 4 is fixedly mounted on the top of the mounting plate 34, and the storage box 4 is used to store the anti-corrosion coating;

[0111] The bottom of the supply box 42 is fixedly mounted on the top of the maintenance plate 35. The supply box 42 supplies the anti-corrosion coating into the scraping plate 310 under the change of pressure. One of the side walls of the supply box 42 is made of a movable flexible material.

[0112] One end of the feed pipe 41 is fixedly connected to the storage box 4, and the other end of the feed pipe 41 is fixedly connected to the supply box 42. The feed pipe 41 is used to transport the anti-corrosion coating from the storage box 4 to the scraping plate 310 through the supply box 42.

[0113] One end of the upper slide bar 43 is fixedly mounted on the side wall of the scraping magnet 37, and the bottom of the upper slide bar 43 is provided with an inclined surface;

[0114] The lower slider 44 is located directly below the upper slider 43. The top of the lower slider 44 is provided with an inclined surface that matches the inclined surface of the upper slider 43. The lower slider 44 changes the pressure in the feed box 42 under the squeezing of the upper slider 43.

[0115] One end of the moving rod 45 is fixedly mounted on the side wall of the lower slider 44;

[0116] One end of the third spring 451 is fixedly mounted on the side wall of the moving rod 45, and the other end of the third spring 451 is fixedly mounted on the guide plate 46. The third spring 451 provides the elastic force required for the moving rod 45 to reset.

[0117] The bottom of the guide plate 46 is fixedly mounted on the top of the maintenance plate 35, and one end of the moving rod 45 is slidably inserted into the guide plate 46;

[0118] One end of the driven rod 47 is fixedly mounted on the side wall of the moving rod 45 , and the other end of the driven rod 47 is fixedly mounted on the side wall of the feeding box 42 .

[0119] When in use, after the maintenance component has completed the operation to clean up the partially fallen anti-corrosion layer, the magnetic change between the scraping electromagnet 36 and the scraping magnet 37 is controlled by the remote control center, so that when the scraping magnet 37 drives the upper slide bar 43 to move, the upper slide bar 43 can squeeze the lower slide bar 44 to move, and the lower slide bar 44 drives the moving rod 45 to move. The moving rod 45 and the guide plate 46 slide together, so that the moving rod 45 can only move horizontally along the guide plate 46. When the moving rod 45 moves, it drives the driven rod 47 to move synchronously, so that the driven rod 47 can move horizontally. The movable portion on the side wall of the feed box 42 is driven to move to one side. When the upper slide bar 43 is separated from the lower slide block 44, the lower slide block 44 moves to the side away from the feed box 42 under the action of the spring 3 451. The movable portion moves back and forth, so that the pressure in the feed box 42 changes, and the anti-corrosion coating stored in the storage box 4 is transported to the feed box 42 through the feed pipe 41, and finally transported to the scraping plate 310, and the anti-corrosion coating is sprayed onto the surface of the steel pipe tower body 1 through the nozzle, thereby covering the surface of the steel pipe tower body 1 that has fallen off.

[0120] At the same time, the anti-corrosion coating is evenly spread by the scraping plate 310 that moves back and forth, so that the anti-corrosion coating can re-cover the surface where the fixed plate 25 and the steel pipe tower body 1 are in contact with the edge area where the coating has fallen off. After the covering is completed, the moving electromagnet 22 and the moving magnet 23 are controlled to reset, so that the fixed plate 25 is again in contact with the surface of the steel pipe tower body 1, thereby performing support and limiting.

[0121] The auxiliary assembly also includes a connecting mechanism, which includes: an expansion rod 5, an extrusion plate 51, a rotating shaft 52, a driven plate 53, and a second connecting plate 54;

[0122] One end of the extension rod 5 is fixedly mounted on the side wall of the connecting plate 1 33;

[0123] The side wall of the extrusion plate 51 slides against the end of the extension rod 5 away from the connecting plate 1 33;

[0124] One end of the rotating shaft 52 is fixedly installed in the extrusion plate 51, and the bottom of the rotating shaft 52 is movably installed on the top of the horizontal plate through a bearing. One end of the horizontal plate is fixedly installed on the side wall of the bottom plate 11;

[0125] The side wall of the driven plate 53 slides against the side wall of the extrusion plate 51;

[0126] The bottom of the second connecting plate 54 is fixedly mounted on the top of the driven plate 53 , and the side wall of the second connecting plate 54 is fixedly mounted on one end of the mounting plate 34 on the other side.

[0127] Furthermore, the connecting plate 1 33 provides a supporting force for the extension rod 5, so that when the compensation push rod 31 is started, the extension rod 5 is synchronously driven to move, so that the extension rod 5 can squeeze the extrusion plate 51 to move, and the extrusion plate 51 flips around the rotating shaft 52, so that the extrusion plate 51 can squeeze the driven plate 53 to move, and the driven plate 53 drives the connecting plate 2 54 to move, so that the maintenance plate 35 on the other side is synchronously moved toward the side where the steel pipe tower body 1 is located. Only one power element is needed to complete it, saving equipment costs.

[0128] In another embodiment different from the aforementioned embodiment, a heating block is fixedly installed on the top of the scraping plate 310 parallel to the bottom plate 11, so that after the anti-corrosion layer coating is sprayed onto the steel pipe tower body 1, the heating block heats and dries the anti-corrosion layer coating to accelerate the curing speed of the anti-corrosion layer coating.

[0129] In another embodiment different from the aforementioned embodiment, a flattening assembly is provided on the top of the scraping plate 310 parallel to the base plate 11. The flattening assembly includes a flat plate, a limiting column, and a power element. The power element drives the flat plate to move back and forth, and the limiting column limits the flat plate so that the limiting column limits the moving direction of the flat plate, so that the flat plate can fully smooth the anti-corrosion pool paint attached to the surface of the steel pipe tower body 1 on the steel pipe tower body 1.

[0130] In another embodiment different from the aforementioned embodiment, a group of electromagnets and magnets are also arranged between the positioning plate 210 and the threaded rod 29, and a driving element is connected to the threaded rod 29. When it is necessary to form a negative pressure between the fixing plate 25 and the steel pipe tower body 1 for adsorption, the group of electromagnets is first energized to separate the electromagnets and the magnets, thereby moving the positioning plate 210 out from one end of the threaded rod 29. At this time, the threaded rod 29 is driven to rotate by the driving element. After the end, the group of electromagnets is energized again to make the electromagnets and the magnets adsorbed together, thereby causing the positioning plate 210 to be stuck in one end of the threaded rod 29 again for limiting.

[0131] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0132] Prolong the service life of the steel pipe tower body 1;

[0133] Reduce maintenance costs;

[0134] Ensure the verticality and overall stability of the steel pipe tower body 1;

[0135] Reduce the difficulty of maintenance operations;

[0136] Improved maintenance efficiency and usage safety.
