Description

Technical Field

[0001] This utility model relates to the field of power tower base structure technology, and in particular to a metal frame for power tower base. Background Technology

[0002] The power tower base is an important component of the power tower foundation. The power tower base bears the weight of the power tower itself, including the weight of the tower body, crossarms, insulators, and conductors. At the same time, it must also withstand various external forces such as conductor tension, wind load, and seismic load, and evenly transfer these loads to the foundation to ensure the stability of the tower.

[0003] The construction of power transmission tower bases typically involves transporting the prefabricated metal frame to the construction site for installation after the foundation construction is completed. During installation, anchor bolts are first accurately embedded in the foundation concrete. Then, the metal frame columns are connected and fixed to the anchor bolts. Next, beams, diagonal braces, and other components are installed sequentially, assembling them into a unified whole through welding or bolting. During installation, it is crucial to control the verticality and horizontality of the metal frame to ensure that its installation accuracy meets design requirements. Finally, concrete is poured to form the power transmission tower base.

[0004] The existing metal frame of the power tower base consists of mounting plates, connecting rods, metal rings, and nuts. When the metal ring is wrapped around the outside of the connecting rod, the connecting rod and the metal ring are fixed together with iron wire. Since there are many intersections between the connecting rod and the metal ring, the iron wire binding method is time-consuming, difficult to operate, and inefficient.

[0005] Therefore, there is an urgent need for a metal frame structure that can quickly complete the fixed connection between the connecting rod and the metal ring. Utility Model Content

[0006] To address the above problems, this utility model provides a metal frame for power tower bases. By using a snap-fit ​​connection structure instead of wire binding, the connecting rod and metal ring are fixedly connected. This method is convenient to operate, highly efficient, and greatly reduces labor intensity.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A metal frame for a power tower base, comprising:

[0009] Mounting plate, connecting rod, metal ring and clips;

[0010] The mounting plates are symmetrically arranged in two sets. The mounting plates are arranged in a circular shape, and a number of mounting holes are equidistantly arranged on the mounting plates along their own axial circumference.

[0011] The connecting rod is provided in several sets, and the two ends of the connecting rod are respectively inserted into the corresponding mounting holes. The connecting rod is connected to the mounting plate by the threaded engagement of the nuts provided on both sides of the mounting plate.

[0012] The metal rings are arranged in several groups, forming a circular ring, and are arranged around the outside of the connecting rod. The metal rings are equidistantly arranged along the length of the connecting rod.

[0013] The buckle is provided in several sets, and the buckle is set at the intersection of the metal ring and the connecting rod, and the buckle connects the metal ring and the connecting rod.

[0014] As an improvement, the buckle includes a locking part and a fastening part;

[0015] Two sets of the engaging parts are arranged in parallel. The engaging parts are arc-shaped and can be elastically expanded. The engaging parts engage with the connecting rod.

[0016] The fastening part is disposed between the engaging parts, the fastening part is U-shaped and protrudes from the engaging part, and the fastening part is engaged with the metal ring.

[0017] As an improvement, the included angle α of the engagement part is greater than 180°, and the diameter of the engagement part is smaller than the diameter of the connecting rod.

[0018] As an improvement, the diameter of the semi-circular connecting part of the fastening part is set to be equal to the diameter of the metal ring.

[0019] As an improvement, the two ends of the buckle are provided with connecting parts that protrude upwards. Two sets of these connecting parts are symmetrically arranged, and each connecting part is provided with a connecting hole.

[0020] As an improvement, adjacent buckles installed on the same connecting rod are connected by a connecting strip.

[0021] As an improvement, the connecting strip includes a strip-shaped portion and an annular portion;

[0022] The strip-shaped portion is long and extends to both sides to form the annular portion, which is circular and is hinged to the connecting hole via a connecting shaft.

[0023] As an improvement, buckles are installed on the connecting rods spaced two sets apart along the circumference of the mounting plate.

[0024] As an improvement, the two ends of the connecting rod are respectively provided with a first thread and a second thread, and the nut includes a positioning nut and a tightening nut. The positioning nut is located at the inner end of the first thread or the second thread and is located between the mounting plates, while the tightening nut is located on the outer side of the mounting plate.

[0025] As an improvement, an auxiliary piece is also fitted onto the outer end of the first thread, and the auxiliary piece is fixed to the connecting rod by tightening nuts provided on both sides.

[0026] The beneficial effects of this utility model are as follows:

[0027] (1) This utility model uses a snap-fit ​​connection structure to replace the wire binding structure to fix the connecting rod and the metal ring. It is convenient to operate, has high work efficiency, and greatly reduces labor intensity. In addition, the snap-fit ​​connection method greatly improves the matching accuracy between the connecting rod and the metal ring, so that the metal frame is more evenly stressed and more stable when applied to the base of the power tower.

[0028] (2) When the metal ring and the connecting rod are connected by the buckle, the adjacent buckles are connected by the connecting strip, thereby controlling the metal rings to be arranged at equal intervals on the connecting rod. The original manual spacing is changed to mechanical spacing, which ensures the parallelism between the metal rings and further improves the matching accuracy between the connecting rod and the metal ring.

[0029] In summary, this utility model has the advantages of convenient installation, simple operation, high work efficiency, and high fitting accuracy, and is especially suitable for the field of power tower base structure technology. Attached Figure Description

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Example 1:

[0043] like Figures 1-7 As shown, a metal frame for a power tower base includes:

[0044] Mounting plate 1, connecting rod 2, metal ring 3 and buckle 4;

[0045] The mounting plate 1 is symmetrically arranged in two sets. The mounting plate 1 is arranged in a circular shape, and a number of mounting holes 11 are equidistantly arranged on the mounting plate 1 along its own axial circumference.

[0046] The connecting rod 2 is provided in several sets. The two ends of the connecting rod 2 are respectively inserted into the corresponding mounting holes 11. The connecting rod 2 is connected to the mounting plate 1 by the threaded engagement of the nuts 21 provided on both sides of the mounting plate 1.

[0047] The metal rings 3 are provided in several groups. The metal rings 3 are arranged in a circular shape and are wrapped around the outside of the connecting rod 2. The metal rings 3 are arranged at equal intervals along the length direction of the connecting rod 2.

[0048] The buckle 4 is provided in several sets, and the buckle 4 is provided at the intersection of the metal ring 3 and the connecting rod 2, and the buckle 4 connects the metal ring 3 and the connecting rod 2;

[0049] It is worth emphasizing that, in order to save costs, while ensuring connection strength, not every intersection of metal ring 3 and connecting rod 2 is equipped with a buckle 4. Instead, buckles 4 are installed on the connecting rod 2 at intervals of two sets along the circumference of the mounting plate 1.

[0050] The buckle 4 includes a locking part 41 and a fastening part 42;

[0051] Two sets of the engaging parts 41 are arranged in parallel. The engaging parts 41 are arc-shaped and can be elastically expanded. The engaging parts 41 engage with the connecting rod 2.

[0052] The fastening part 42 is disposed between the engaging parts 41. The fastening part 42 is U-shaped and protrudes from the engaging part 41. The fastening part 42 is engaged with the metal ring 3.

[0053] Furthermore, the diameter of the semi-circular connecting portion 421 of the fastening portion 42 is equal to the diameter of the metal ring 3.

[0054] Specifically, when the buckle 4 connects the metal ring 3 and the connecting rod 2, the engaging part 41 is first put onto the connecting rod 2. When the engaging part 41 is put onto the connecting rod 2, the engaging part 41 will expand elastically, thereby making the engaging part 41 firmly fixed on the connecting rod 2. Finally, the fastening part 42 fastens the metal ring 3 onto the connecting rod 2.

[0055] Furthermore, to ensure the secure connection between the engaging part 41 and the connecting rod 2, the included arc angle α of the engaging part 41 is preferably greater than 180°, so that the engaging part 41 can partially cover the connecting rod 2. Moreover, the diameter of the engaging part 41 is preferably smaller than the diameter of the connecting rod 2. For example, if the diameter of the connecting rod 2 is 5cm, then the diameter of the engaging part 41 is 4.95cm, so that after the engaging part 41 expands, it can be tightly fitted onto the connecting rod 2.

[0056] Example 2:

[0057] Referring to Example 1, the difference between Example 2 and Example 1 lies in the following:

[0058] like Figure 4 , Figure 8 and Figure 9 As shown, the two ends of the buckle 4 are provided with connecting parts 43 protruding upwards. Two sets of connecting parts 43 are symmetrically arranged, and connecting holes 431 are provided on the connecting parts 43.

[0059] Furthermore, adjacent buckles 4 installed on the same connecting rod 2 are connected by connecting strips 5.

[0060] Specifically, the connecting strip 5 includes a strip-shaped portion 51 and an annular portion 52;

[0061] The strip-shaped portion 51 is elongated and extends to both sides to form the annular portion 52. The annular portion 52 is circular and is hinged to the connecting hole 431 via a connecting shaft.

[0062] Currently, the metal rings 3 are manually fitted onto the connecting rod 2, and the spacing between the metal rings 3 is also manually adjusted. This results in a large error in the spacing between the metal rings 3. The spacing of the metal rings 3 is crucial for the uniform stress distribution on the metal frame. By using the connecting strip 5, the spacing between the metal rings 3 can be set to a fixed length. Furthermore, before installing the buckles 4, the buckles 4 are connected in series using the connecting strip 5. Then, when installing the buckles 4, the series of buckles 4 are snapped together one after another, making the operation more convenient.

[0063] Example 3:

[0064] Referring to Examples 1 and 2, the difference between Example 3 and Examples 1 and 2 is that:

[0065] like Figure 3 , 6 As shown, the connecting rod 2 has a first thread 22 and a second thread 23 at both ends. The nut 21 includes a positioning nut 211 and a tightening nut 212. The positioning nut 211 is located at the inner end of the first thread 22 or the second thread 23 and is located between the mounting plates 1. The tightening nut 212 is located on the outer side of the mounting plate 1.

[0066] Furthermore, an auxiliary piece 6 is also sleeved on the outer end of the first thread 22, and the auxiliary piece 6 is fixed to the connecting rod 2 by tightening nuts 61 provided on both sides.

[0067] It should be noted that the existing threads on the connecting rods 2 of the metal frame are all set to be too long. This results in a lack of positioning reference when the connecting rods 2 and the mounting plate 1 are assembled. In this application, the inner ends of the first thread 22 and the second thread 23 are pre-set so that when the positioning nut 211 rotates to the inner ends of the first thread 22 and the second thread 23, it can no longer rotate inward. Using the inner ends of the first thread 22 and the second thread 23 as the installation reference, when the positioning nut 211 and the mounting plate 1 are installed, the positioning nut 211 is used as the reference. After the mounting plate 1 abuts against the positioning nut 211, the tightening nut 212 is screwed in. This ensures that the mating position of the mounting plate 1 and the connecting rod 2 of each metal frame is consistent, thus ensuring the consistency of the finished metal frame.

[0068] In addition, the auxiliary plate 6 increases the contact area between the metal frame and the ground, effectively dispersing external loads such as wind and seismic forces transmitted from the power tower to the base, thus providing the power tower with overturning resistance.

[0069] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
