Description

Technical Field

[0001] The utility model relates to the technical field of power transmission and distribution equipment, in particular to a base device of an iron tower. Background Art

[0002] The tower's base is the foundation of the entire structure. It not only bears the tower's own weight but also withstands the effects of natural forces such as wind and earthquakes. The base is typically embedded in a high-strength concrete foundation to ensure the tower's stability and safety.

[0003] During the construction process, when existing tower base assemblies are embedded in the concrete foundation, factors such as uneven concrete vibration, varying foundation settlement, and insufficient installation precision often cause the upper end surface of the base assembly to become inconsistent with the horizontal plane, resulting in deviations in the base assembly's levelness. This deviation not only affects the overall stability and safety of the tower but can also cause inconvenience to subsequent installation work, increasing construction difficulty and costs. Furthermore, once a level problem is discovered, adjustments are extremely cumbersome, requiring recalibration or even dismantling and reconstruction, which undoubtedly increases the time and financial burden of the project. Therefore, improvements are urgently needed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a base device for an iron tower.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] A base device for an iron tower includes a base body embedded in a concrete foundation during installation, a top plate, and stud bolts; three lower internally threaded tubes are evenly distributed and fixedly connected in an annular manner to the upper end of the base body; an upper internally threaded tube corresponding to the lower internally threaded tubes is fixedly connected to the lower end of the top plate; the threads at both ends of the stud bolts have opposite rotation directions, and the two ends are respectively threadedly connected to the corresponding lower internally threaded tubes and upper internally threaded tubes; a plurality of connecting bolts are fixedly connected to the upper end of the top plate.

[0007] Preferably, the base includes a base plate, side plates respectively located around the base plate and with upper ends fixed to the base plate, and a plurality of short rods fixed to the side plates; an exhaust hole is provided at the upper end of the base plate.

[0008] Preferably, a rubber shock-absorbing support for supporting the top plate is provided at the upper end of the seat body.

[0009] Preferably, a lower positioning ring for embedding a rubber shock-absorbing support is provided at the upper end of the seat body, and an upper positioning ring for embedding a rubber shock-absorbing support is provided at the lower end of the top plate.

[0010] Preferably, a clamping portion is provided in the middle of the stud bolt.

[0011] The above technical solution has the following advantages:

[0012] After the base assembly is embedded in the concrete foundation, the utility model uses stud bolts for leveling, enabling flexible and precise adjustment of the levelness of the upper end surface of the base assembly. This effectively solves the problem of the upper end surface of the base assembly not being able to align with the horizontal plane in traditional methods. This improvement not only effectively improves the accuracy and stability of the base assembly installation, but also significantly reduces the inconvenience and additional costs caused by level deviation during subsequent installation work, ensuring the safety and reliability of the tower's overall structure.

DETAILED DESCRIPTION

[0022] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0023] As shown in the accompanying drawings, a base device of an iron tower includes a base body 1, a top plate 2, and stud bolts 3 embedded in a concrete foundation (not shown in the figure, the same for the rest) during installation; three lower internally threaded tubes 4 are evenly distributed in a ring and fixed to the upper end of the base body 1; an upper internally threaded tube 5 corresponding to the lower internally threaded tube 4 is fixed to the lower end of the top plate 2; the thread rotation directions of the two ends of the stud bolt 3 are opposite, and the two ends are respectively threadedly connected to the corresponding lower internally threaded tube 4 and upper internally threaded tube 5, and internal threads compatible with the stud bolts 3 are arranged in the lower internally threaded tube 4 and the upper internally threaded tube 5; a plurality of connecting bolts 6 are fixed to the upper end of the top plate 2.

[0024] As a further improvement to this embodiment, the base body 1 comprises a base plate 7, side plates 8 positioned around the base plate 7 and fixedly connected to the base plate 7 at their upper ends, and a plurality of short rods 9 fixedly connected to the side plates 8. The base plate 7 is provided with vent holes 10 at its upper end. This structure of the base body 1, with the short rods 9 embedded in the concrete foundation, provides a more secure connection to the concrete foundation. The vent holes 10 also allow for the exhaust of internal air, ensuring the compactness of the concrete foundation. When the base body 1 is installed, the base plate 7 can be aligned with, or slightly lower than, the upper end of the concrete foundation.

[0025] As a further improved technical solution of this embodiment, a rubber shock-absorbing support 11 is provided on the upper end of the base body 1 for supporting the top plate 2. The rubber shock-absorbing support 11 can provide a certain bearing capacity and also achieve a certain degree of shock absorption.

[0026] As a specific technical solution for installing the rubber shock-absorbing support 11 in this embodiment, the upper end of the base body 1 is provided with a lower locating ring 12, into which the rubber shock-absorbing support 11 is embedded, and the lower end of the top plate 2 is provided with an upper locating ring 13, into which the rubber shock-absorbing support 11 is embedded. The ends of the rubber shock-absorbing support 11 are respectively embedded in the lower locating ring 12 and the upper locating ring 13. This structure is characterized by easy assembly, disassembly and maintenance, and it is obvious that bolt connection methods or other methods can also be used.

[0027] As a further improved technical solution of this embodiment, a clamping portion 14 is provided in the middle of the stud bolt 3. The clamping portion 14 in this embodiment is in the shape of a regular hexahedron. Obviously, the clamping portion 14 can also adopt other shapes that are convenient for tool clamping.

[0028] During use, the base body 1 is pre-buried in the concrete foundation, and then the top plate 2 is leveled by screwing the stud bolts 3, and then the frame of the tower can be connected by connecting bolts 6; when adjusting the stud bolts 3, the rubber shock-absorbing support 11 should be compressed to a certain extent to ensure the seismic effect.

[0029] After the base device of the present invention is embedded in the concrete foundation, the levelness is adjusted by adopting stud bolts 3, which can flexibly and accurately adjust the levelness of the upper end surface of the base device, thereby effectively solving the problem that the upper end surface of the base device cannot be kept consistent with the horizontal plane in the traditional method.

[0030] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
