Description

Technical Field

[0001] The present invention belongs to the technical field of concrete poles, and more specifically, particularly relates to a concrete pole. Background Art

[0002] Concrete poles, also known as cement poles, are a type of supporting structure widely used in power, communication and lighting systems. They are mainly used for the installation of overhead lines. The core material is reinforced concrete. By combining the steel skeleton with concrete, a columnar component with compression resistance, bending resistance and durability is formed. In the early 20th century, with the development of the electric power industry, the problems of easy decay and low strength of traditional wooden poles became increasingly prominent. Concrete poles have gradually become the mainstream due to their economy and stability. At present, they have become one of the core infrastructures for urban and rural power grid construction.

[0003] After searching the Chinese patent with the announcement number "CN114658280B", it is disclosed that "a concrete pole and its installation method" is disclosed. When installing the concrete pole, it includes a plurality of cylindrical unit concrete poles and a plurality of connecting components that connect the unit concrete poles in series, which is convenient for quick docking and installation, simple and fast operation, and convenient for docking of each unit concrete pole, which can be more convenient to operate during loading and unloading, saving manpower and material resources, and improving work efficiency;

[0004] Based on the above search and combined with the prior art, it was found that the above patent has certain defects. However, when the bottom rod of the concrete pole is installed, the anchor flange lacks a self-locking structure. In the process of connecting and fixing the bottom rod to the foundation, the bottom rod may be slightly touched or shaken by external force or slightly uneven force during operation by the installer, causing the bottom rod to shift or rotate. This requires the installer to spend more time and energy to adjust the position of the bottom rod to ensure the accuracy of its installation, thereby extending the installation time and reducing the installation efficiency. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a concrete pole to solve the above problems.

[0006] A concrete pole comprises a concrete pole body, a foundation flange is arranged at the lower end of the concrete pole body, a plurality of grooves are arranged on the circumferential surface of the foundation flange, and a foundation bolt is threadedly installed inside each of the grooves:

[0007] The circumferential surface of the anchor flange is symmetrically provided with fastening structures;

[0008] The fastening structure includes a half-ring, both of which are made of flexible resetting metal material, and multiple embedded blocks are fixedly installed on the inner side of the two half-rings, each of which is made of flexible plastic material, each of which is located inside the partition groove, and each of which has a circular groove inside.

[0009] Preferably, each circular groove is provided with a one-way bearing, the outer ring of each one-way bearing is fixedly mounted on the inner wall of the circular groove, each embedded block is provided with a through groove, each through groove is communicated with the circular groove, and the inner ring of each one-way bearing is fixedly mounted with a rotating shaft.

[0010] Preferably, a slide groove is provided inside each of the rotating shafts, a slide column is slidably installed inside each of the slide grooves, a limiting groove is symmetrically provided on the side wall of each of the slide grooves, a magnetic strip is fixedly installed on the inner wall of each of the limiting grooves, and a magnetic block is symmetrically fixedly installed on the side wall of each of the slide columns.

[0011] Preferably, each of the magnetic blocks is located inside the limiting groove, each of the magnetic blocks is slidably installed with the limiting groove, each of the magnetic blocks is magnetically attracted to the magnetic strip, a cover plate is fixedly installed at the lower end of each sliding column, a hexagonal groove is opened inside each cover plate, a hexagonal head is provided at the upper end of each anchor bolt, each of the hexagonal groove is clamped with the hexagonal head, and a control rod cap is fixedly installed at the upper end of each sliding column.

[0012] Preferably, a rectangular piece is fixedly mounted on the lower end of each of the two semi-ring members, both of the two rectangular pieces are made of flexible reset metal material, and a stretchable flexible dustproof film is fixedly mounted on the inner side of each of the rectangular pieces.

[0013] Preferably, a threaded connector is symmetrically threadedly installed between the two semi-ring members, and the two semi-ring members and the rectangular member can be assembled and fastened to the circumferential surface of the anchor flange through the threaded connector.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, by setting a fastening structure, the staff can press down the control pole cap, so that the sliding column generates a radial force to drive the inner hexagonal groove on the cover plate to be actively embedded in the hexagonal head as a whole, thereby completing the clamping and fixing of the hexagonal head on the anchor bolt, thereby helping the staff to more accurately position and install the concrete pole body and the anchor flange, ensuring that the overall verticality and position of the concrete pole body meet the design requirements, avoiding subsequent problems caused by installation deviations, and improving efficiency;

[0016] In the present invention, since the rotation of the hexagonal head needs to be indirectly rotated through the rotating shaft, a one-way bearing is arranged inside the through groove, and the rotating shaft is connected to the one-way bearing, so that the rotation direction of the cover plate can be suppressed, so that the anchor bolt will not easily rotate in the opposite direction even if the concrete pole body is subjected to external forces such as vibration during use or installation, thereby enhancing the stability and reliability of the anchor bolt connection and ensuring the safety of the overall structure of the concrete pole body;

[0017] In the present invention, when the anchor bolt is installed on the concrete pole body, the height parallelism between the hexagonal heads on the anchor bolt is likely to have a certain difference. By providing a slide groove inside the rotating shaft, the staff can control the movement of the slide column and the cover plate by manipulating the pole cap, so that the cover plate can be adjusted to a certain height, thereby increasing its applicability and ensuring the clamping strength between the inner hexagonal groove in the cover plate and the hexagonal head.

[0018] In the present invention, by providing a magnetic block and a magnetic strip, when the staff operates the sliding column, the magnetic block can be driven to move on the magnetic strip, and auxiliary magnetic fixation can be performed, thereby facilitating the control of the sliding column;

[0019] In the present invention, a rectangular piece is arranged below the semi-ring piece, and a stretch-type flexible dust-proof film is arranged inside the rectangular piece. At the same time, since the semi-ring piece of the fastening structure is around the anchor bolt, when the staff puts the semi-ring piece on the circumferential surface of the anchor flange, the rectangular piece and the stretch-type flexible dust-proof film can naturally protect the anchor flange, reduce the entry of dust and other impurities into the gap between the anchor bolt and the anchor flange, reduce the possibility of rust, and improve the protection.

[0020] In the present invention, by setting the material of the semi-ring member and the rectangular member to a flexible reset metal material, and setting the material of the embedded block to a flexible plastic material, the fastening structure can be deformed to a certain extent, making it convenient to put the fastening structure on the anchor flange.

DETAILED DESCRIPTION

[0030] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] See also Figure 1 - Figure 8 The present invention provides a concrete pole, comprising a concrete pole body 11, a foundation flange 12 is provided at the lower end of the concrete pole body 11, a plurality of grooves 13 are provided on the circumferential surface of the foundation flange 12, and a foundation bolt 14 is threadedly installed inside each groove 13:

[0032] The circumferential surface of the anchor flange 12 is symmetrically provided with fastening structures;

[0033] The fastening structure includes a half ring 15, and the two half rings 15 are both made of flexible reset metal material (flexible reset metal material is a metal material with both elastic deformation ability and shape recovery characteristics, such as spring steel, stainless steel, etc.), and a plurality of embedded blocks 16 are fixedly installed on the inner side of the two half rings 15, and each embedded block 16 is made of flexible plastic material, and each embedded block 16 is located inside the partition groove 13, and a circular groove 17 is opened inside each embedded block 16, and a one-way bearing 18 is arranged inside each circular groove 17, and the outer ring of each one-way bearing 18 is fixedly installed with the inner wall of the circular groove 17, and a through groove 19 is opened inside each embedded block 16, and each through groove 19 is communicated with the circular groove 17, and the inner ring of each one-way bearing 18 (the inner ring of the one-way bearing 18 can rotate in the opposite direction to the loosening rotation direction of the anchor bolt 14) is fixedly installed with a rotating shaft 21;

[0034] Since the rotation of the hexagonal head 33 needs to be indirectly rotated through the rotating shaft 21, by arranging a one-way bearing 18 inside the through groove 19 and connecting the rotating shaft 21 to the one-way bearing 18, the rotation direction of the cover plate 27 can be suppressed, so that during the use or installation of the concrete pole body 11, even if it is subjected to external forces such as vibration, the anchor bolt 14 will not easily rotate in the opposite direction, thereby enhancing the stability and reliability of the connection of the anchor bolt 14 and ensuring the safety of the overall structure of the concrete pole body 11.

[0035] Each rotating shaft 21 is provided with a sliding groove 22, each sliding groove 22 is slidably provided with a sliding column 23, each sliding groove 22 is symmetrically provided with a limiting groove 24 on the side wall, each limiting groove 24 is fixedly provided with a magnetic strip 25 on the inner wall, each sliding column 23 is symmetrically fixedly provided with a magnetic block 26 on the side wall, each magnetic block 26 is located inside the limiting groove 24, each magnetic block 26 is slidably installed with the limiting groove 24, and each magnetic block 26 is magnetically attracted to the magnetic strip 25;

[0036] When the anchor bolt 14 is installed on the concrete pole body 11, the height parallelism between the hexagonal heads 33 on the anchor bolt 14 is likely to have a certain difference. By providing the slide groove 22 inside the rotating shaft 21, the staff can control the movement of the slide column 23 and the cover plate 27 by manipulating the pole cap 29, so that the cover plate 27 can be adjusted to a certain height, thereby increasing its applicability and ensuring the clamping strength between the inner hexagonal groove 28 in the cover plate 27 and the hexagonal head 33;

[0037] By providing the magnetic block 26 and the magnetic strip 25 , when the staff operates the slide column 23 , they can drive the magnetic block 26 to move on the magnetic strip 25 , and can perform auxiliary magnetic fixation, thereby facilitating the control of the slide column 23 .

[0038] A cover plate 27 is fixedly mounted on the lower end of each sliding column 23, and a hexagonal groove 28 is formed inside each cover plate 27. A hexagonal head 33 is formed on the upper end of each anchor bolt 14, and each hexagonal groove 28 is clamped with the hexagonal head 33. A control rod cap 29 is fixedly mounted on the upper end of each sliding column 23.

[0039] By setting up the fastening structure, the staff can press down the operating rod cap 29, so that the sliding column 23 generates a radial force to drive the inner hexagonal groove 28 on the cover plate 27 to be actively embedded in the hexagonal head 33 as a whole, thereby completing the clamping and fixing of the hexagonal head 33 on the anchor bolt 14, and then helping the staff to more accurately position and install the concrete pole body 11 and the anchor flange 12, ensuring that the overall verticality and position of the concrete pole body 11 meet the design requirements, avoiding subsequent problems caused by installation deviations, and improving efficiency.

[0040] A rectangular piece 31 is fixedly installed at the lower end of the two semi-ring members 15. The two rectangular members 31 are made of flexible reset metal material. A tensile flexible dust-proof membrane 32 is fixedly installed on the inner side of each rectangular member 31. A threaded connector 34 is symmetrically threadedly installed between the two semi-ring members 15. The two semi-ring members 15 and the rectangular member 31 can be assembled and fastened to the circumferential surface of the anchor flange 12 through the threaded connector 34.

[0041] By arranging a rectangular member 31 below the semi-ring member 15 and arranging a stretch-type flexible dust-proof film 32 inside the rectangular member 31, and at the same time, since the semi-ring member 15 of the fastening structure is around the anchor bolt 14, when the staff puts the semi-ring member 15 on the circumferential surface of the anchor flange 12, the rectangular member 31 and the stretch-type flexible dust-proof film 32 can naturally protect the anchor flange 12, reduce dust and other impurities from entering the gap between the anchor bolt 14 and the anchor flange 12, reduce the possibility of rust, and improve protection;

[0042] By setting the material of the semi-ring member 15 and the rectangular member 31 to be a flexible reset metal material, and setting the material of the embedded block 16 to be a flexible plastic material, the fastening structure can be deformed to a certain extent, making it convenient to put the fastening structure on the anchor flange 12.

[0043] Working principle:

[0044] The first step is that when carrying out the installation work, the staff first needs to use the anchor bolts 14 to firmly fix the concrete pole body 11 and the anchor flange 12 at the pre-selected installation position. After completing this step, the staff needs to slightly bend the semi-ring member 15 and the rectangular member 31 to both sides so that they can be smoothly sleeved on the circumferential surface of the anchor flange 12. In this process, special attention needs to be paid to accurately adjust each embedded block 16 on the semi-ring member 15 to the corresponding compartment 13. Then, the staff follows the same operation steps to install another semi-ring member 15 on the circumferential surface of the anchor flange 12. Finally, the two semi-ring members 15 are docked with each other using the threaded connector 34, and the operation is continued until the two semi-ring members 15 can tightly wrap and tighten the circumferential surface of the anchor flange 12;

[0045] In the second step, after the installation and docking of the semi-ring member 15 are completed, the staff needs to use the control rod cap 29 to press the slide post 23 downward. When the slide post 23 is pressed, a radial force will be generated. This radial force will drive the magnetic block 26 to move downward in the slide groove 22 and the limit groove 24 respectively. With the movement of the slide post 23, the cover plate 27 will be driven to be actively embedded in the hexagonal head 33 as a whole, thereby completing the fastening;

[0046] In the third step, if it is found that the hexagonal head 33 on the anchor bolt 14 and the inner hexagonal groove 28 inside the cover plate 27 are not parallel, the staff needs to rotate the control rod cap 29. When the control rod cap 29 rotates, it will drive the sliding column 23 to generate a radial force. This radial force will cause the rotating shaft 21 to rotate through the inner ring of the one-way bearing 18. Since the cover plate 27 is connected to the rotating shaft 21, the cover plate 27 will rotate synchronously when the rotating shaft 21 rotates. Then, when the inner hexagonal groove 28 inside the cover plate 27 is parallel to the hexagonal head 33, the rotation of the control rod cap 29 should be stopped immediately, and then the inner hexagonal groove 28 on the cover plate 27 is accurately aligned with the hexagonal head 33 and pressed down to complete the clamping operation, thereby achieving tightening.

[0047] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
