Wire pole traction steel cable fastening device for electric power transmission and installing method of wire pole traction steel cable fastening device

Abstract

The invention discloses a wire pole traction steel cable fastening device for electric power transmission and an installing method of the wire pole traction steel cable fastening device. A shell is included. The upper portion of the side wall of the interior of the shell is fixedly connected with a fixing rod. A rotation rod is fixedly connected to the lower portion of the side wall of the interior of the shell. The outer side wall of the rotation rod is in cup joint with a winch and a first gear. A steel stranded wire is wound around the outer side walls of the winch and a guiding wheel in aconnecting manner. A guiding groove is formed in the top of the shell. A protection cover is hinged to the top of the shell. A limiting base is welded to the side wall of the interior of the shell. The limiting base is internally in sliding connection with a fixing base. The top of the shell is evenly provided with four fixing assemblies with the tops penetrating through the bottom, the problems that when a cement stay wire disc and other heavy objects need to be placed, personal injuries can be caused to operation personnel or the traction effect cannot be achieved due to the insufficient dead load are prevented, and the work efficiency and safety guarantee of the operation personnel are effectively improved.

Problems solved by technology

[0002] With the needs of the development of science and technology and industrial production, electric power technology has gradually been widely used in communication, transportation, power, etc., and the demand for electric power in society has also increased sharply. It gradually evolved into AC transmission. AC transmission has many advantages, such as reducing the loss in power transmission, increasing the speed and transmission length. Electricity poles were one of the important infrastructures in early China. All kinds of early electric poles were made from wood The poles started, even including high-voltage electric poles with low voltage levels. Later, due to the development of steel and reinforced concrete, and technical requirements, these two materials replaced most of the wooden poles, and the applicable wood was gradually scarce. It is basically difficult to see wooden poles inside. Later, due to the development of steel bars and concrete, combined with technical research, and using the principle of centrifugal force to manufacture, reinforced concrete conical cement poles and equal-diameter cement poles replaced most of the wooden poles. The pole is durable, corrosion-resistant, temperature-resistant, high-strength, and crack-resistant. For this reason, although cement poles have replaced wooden poles, the weight of the cement pole itself is relatively large. After installation, most traction cables need to be added, but most traction lines now One end of the cable is fixed to the electric pole, and the other end is fixed on the ground with the gravity of the cement cable tray itself for traction or pre-buried and then concrete poured. Because the length of the traction cable is pre-cut, the length of the traction cable to the electric pole There are certain limitations. The traction device and the traction steel cable are not easy to remove after concrete pouring. It is extremely inconvenient to install the cement cable reel to pull the utility pole due to the self-weight of the cement cable reel, and when installing the cement cable reel There are also some potential safety hazards. For this reason, a power transmission pole traction cable fastening device and its installation method are proposed.
