Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transmission equipment technology, and in particular to an assembled power transmission tower. Background Technology
[0002] Power transmission and transformation towers are steel structures used in power transmission and transformation projects to directly or indirectly support or fix conductors such as high-voltage cables and overhead lines. With the continuous development and progress of economy and technology, power transmission and transformation towers have been widely used in the power industry as an important power equipment.
[0003] Currently, power transmission towers mainly adopt angle steel welded structures or bolt-fixed truss structures. Although they are widely used, the following significant problems still exist in actual engineering:
[0004] Traditional angle steel towers require extensive welding work at high altitudes, are greatly affected by weather (such as rain, snow, and strong winds), and have a long construction period (taking a 110kV tower as an example, the average installation time is 5 to 7 days).
[0005] In addition, angle steel components are produced on a customized basis, and parts for different tower types cannot be interchanged. If there is local damage (such as rust or deformation), on-site cutting and welding are required, which is time-consuming and costly.
[0006] Therefore, this application provides modular power towers to meet the requirements. Utility Model Content
[0007] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose an assembled power tower.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] An assembled power transmission tower includes: a foundation, a pre-embedded sleeve, main columns, flanges, fixed joints, trusses, and fixed seats. The pre-embedded sleeve is built into the upper part of the foundation. Four main columns are installed in the upper part of the pre-embedded sleeve. Flanges are welded to both ends of the main columns. The mating surfaces of the flanges are integrally provided with positioning grooves and positioning bosses. Fixed joints are installed on the upper side of the main columns. A support is provided at one end of the fixed joint. A truss is installed on the side of the main columns. A fixed seat is welded to the other end of the truss.
[0010] Preferably, the flange is embedded inside the pre-embedded sleeve, and the main column is fixed to the pre-embedded sleeve by high-strength bolts passing through the bolt holes of the flange.
[0011] Preferably, the positioning groove is annular, the positioning boss is cylindrical, and the positioning groove and the positioning boss fit together.
[0012] Preferably, flanges are welded to both ends of the main column, and the two sets of main columns are connected by positioning grooves and positioning bosses, and fixed by high-strength bolts passing through the bolt holes of the flanges.
[0013] Preferably, the support is rectangular, and bolt holes are provided at all four ends of the support on the outside of the fixed joint.
[0014] Preferably, the fixed joint is installed on the surface of the main column by screwing high-strength bolts onto the support.
[0015] Preferably, the inner side of the fixing joint is provided with a rectangular groove, and the front and top of the fixing joint are provided with rectangular openings.
[0016] Preferably, the fixed joint is rectangular, the fixed seat fits into the groove of the fixed joint, the fixed seat is embedded in the groove of the fixed joint, and the truss is installed in the fixed joint on the side of the main column through the fixed seat.
[0017] Preferably, bolt holes are provided on both sides of the fixed joint and the fixed seat, and the bolt extends from the fixed joint inward through the fixed seat and outward to the other end of the fixed joint, so that the fixed seat is installed in the fixed joint.
[0018] Preferably, the truss is an I-beam structure.
[0019] Compared with the prior art, this utility model has at least the following beneficial effects:
[0020] In the above scheme, the main column can be quickly installed with the pre-embedded sleeve. The main columns are connected to each other through positioning grooves and positioning bosses. The fixed joint can be flexibly installed on the surface of the main column according to the usage requirements through the support for lateral connection. The front and top of the fixed joint are provided with rectangular openings to facilitate the installation of the fixed seat and truss on the fixed joint from top to bottom, making disassembly and assembly more convenient. By setting several sets of splicing steel structure components, the tower can be modularly assembled. Modular installation greatly improves the installation efficiency of the tower compared with traditional construction methods, effectively improving the construction progress of the tower.
[0021] In the above scheme, the main column can be quickly installed with the pre-embedded sleeve. The main columns are connected by positioning grooves and positioning bosses, and fixed by high-strength bolts through the bolt holes of the flange. The main column adopts an inner flange nesting structure, which can realize the transmission of torsional force between tower sections. The double positioning design of the flange makes the wind load resistance strong.
[0022] In the above scheme, the main columns used for vertical support and the trusses for horizontal connection are both modular. Damaged tower sections can be replaced individually without the need for overall dismantling, making tower maintenance more convenient. Attached Figure Description
