Abstract
Description
Technical Field
[0001] This utility model relates to the field of cableway construction for power transmission lines, and in particular to a prefabricated gantry support for cableways for power transmission lines. Background Technology
[0002] The Tibetan region has a vast area, complex terrain and geology, high altitude, and long winters. The construction quality of high-voltage transmission lines is a key factor in ensuring stable and effective power transmission. Therefore, it is necessary to solve the technical challenges of constructing high-voltage transmission lines in the Tibetan region.
[0003] Cableway transportation addresses the significant difficulties in transporting materials for power transmission line construction in Tibetan areas, where traditional methods are insufficient. Cableway transportation, with its advantages of low cost, high efficiency, convenient construction, and immunity to weather conditions, plays a crucial role in power transmission line construction. During cableway erection and installation, transporting various components up the mountain manually is extremely difficult. In the Qinghai-Tibet Plateau region, with its high altitude and thin air, carrying heavy components is even more challenging. Therefore, the design of cableway components should minimize the weight of individual components to facilitate manual transport, easy assembly, and shorten construction time.
[0004] A gantry is an auxiliary device for supporting ropes and is an important component of power transmission line cableways. The overall weight of the gantry is relatively large, making transportation difficult. Utility Model Content
[0005] The present invention aims to provide a prefabricated gantry support for power transmission line cableways to solve the problem of difficulties in manpower and transportation of large items during cableway construction in high-altitude mountainous areas.
[0006] This solution includes a prefabricated gantry support for a power transmission line cableway, comprising a column, a base plate fixedly connected to the bottom of the column, and a base plate detachably connected to the base plate.
[0007] Furthermore, the base includes a detachably connected main board and wing plates.
[0008] Furthermore, reinforcing ribs are welded between the base plate and the column.
[0009] Furthermore, the column and the base plate are welded together.
[0010] Furthermore, two bolt holes are provided on both sides of the motherboard and on the wing plate, and the motherboard and the wing plate are connected by a first connecting bolt.
[0011] Furthermore, the base plate is circular, with four bolt holes arranged in a circular array on the base plate, two bolt holes on the main plate, and one bolt hole on each of the two wing plates. The four bolt holes on the base plate are connected to the two bolt holes on the main plate and the bolt holes on the two wing plates respectively by a second connecting bolt.
[0012] Furthermore, the main board and wing plates are machined from channel steel. The base made of channel steel is lightweight, high-strength, stable, and easy to assemble.
[0013] The working principle and beneficial effects of this solution: This solution has a simple structure, is easy to disassemble and install, and can be transported to the high-altitude area in sections before use. It is lightweight and easily transported to the work area, where it can be assembled using the first connecting bolt and the second connecting bolt. The basic solution's base structure is simple, rationally designed, low-cost, and easy to manufacture; construction is simple and quick, requiring no maintenance period; the components are connected by bolts, making assembly convenient and efficient.
