Description

Technical Field

[0001] The utility model relates to the technical field of power towers, and in particular to a bottom fixing device of a power tower. Background Art

[0002] The power tower is a kind of supporting equipment for the power line and is a steel structure product. The power transmission tower is generally set up outdoors or even in the wild. Before installing the power transmission tower, the construction workers will generally dig a foundation pit at the location where the power transmission tower is to be installed, and then pour concrete in the foundation pit, and pre-embed a number of bolts for installing the power tower in the poured concrete. This concrete structure is called the installation foundation of the power transmission tower. The power tower is assembled on the foundation, so that the stability of the power tower can be guaranteed through the base to prevent the power tower from being damaged by external forces during strong winds or earthquakes. Therefore, fixing devices are required when installing the power tower.

[0003] In the existing technology, a communication tower bottom fixing device with the publication number of CN215485053U is proposed, which relates to the field of communication tower bottom fixing technology. The communication tower bottom fixing device includes a base, a fixing plate, a tower base and a vertical plate. A fixing assembly is arranged inside the base. The fixing assembly includes a sleeve and two screw rods. The sleeve is rotatably connected to the inside of the base. Limiting grooves are provided on both sides of the sleeve. The two screw rods are arranged inside the sleeve. One end of the two screw rods is fixedly connected to the limiting blocks. The two limiting blocks are respectively slidably connected to the inside of the two limiting grooves. The two screw rods respectively penetrate the two side walls of the vertical plate and are threadedly connected to the vertical plate. Limiting assemblies are arranged on both sides of the base. The communication tower bottom fixing device is conducive to fixing the side plates and the tower base, improving the stability of the tower base fixation, and facilitating installation and disassembly.

[0004] In order to solve the problems that the fixing structure at the bottom of most towers is inconvenient and the installation and disassembly are troublesome, which greatly limits the scope of use of the fixing structure at the bottom of the tower, and the fixing structure of the fixing legs at the bottom of the tower is not stable enough and the fixing bolts are easy to loosen, the existing technology uses fastening bolts to connect with threads to limit and fix the base of the tower. However, the power towers generally have poor seismic resistance, which causes the power towers to be damaged due to vibration, thereby affecting the working efficiency and service life of the power towers. In addition, the fixing device is not easy to adjust and is not stable enough, resulting in poor practicality of the device, which in turn leads to the problem of reduced utilization efficiency of the fixing device.

[0005] The purpose of the utility model is to provide a bottom fixing device of a power tower to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
