specific Embodiment approach

[0065] As a specific embodiment of the installation method of a split type power tower group provided by the present invention, after positioning the tower body 2 on the top of the tower leg 1, it also includes:

[0066] Remove the fixed pulley 8 and the swing arm from the tower leg 1, and install them on the corresponding position of the tower body 2, install the auxiliary rail on the same side where the tower body 2 is located on the guide rail, install the tower head through the auxiliary rail and the guide rail, and install the second A traction rope 3 and a second traction rope 4 are respectively connected to both sides of the tower head.

[0067] In order to reduce the use of materials, the reinforcement bar, the swing arm and the fixed pulley 8 can all be detachably connected in this application. After the tower body 2 is installed, the swing arm and the fixed pulley 8 can be installed at the pre-specified position on the top of the tower body 2. On, for the installatio...

Abstract

The invention provides a split type electric power tower group installation method, and belongs to the technical field of tower group assembly. The split type electric power tower group installation method comprises the steps that tower legs are erected, wherein anchor rods are installed at the centers of the tower legs; and a tower body is assembled, and limiting pieces which are in sliding fit with guide rails are installed on the tower body. One end of a first traction rope is connected to the bottom end of the tower body, and the other end of the first traction rope bypasses a guide wheel from the top ends of the tower legs and is finally connected with a first traction machine; a second traction rope is connected to the bottom end of the tower body, the second traction rope and the first traction rope are arranged at intervals, and the other end of the second traction rope bypasses a swing arm and a second traction machine; and the tower body slides along the guide rails through the first traction machine and the second traction machine, when the tower body moves to the top ends of the guide rails, one side of the tower body is connected to enable the other side of the tower body to swing and be buckled on the tower legs, the tower body is positioned on the tower legs, and a tower head and a cross arm are installed. According to the split type electric power tower group installation method, the installation steps of the tower body are simplified, the material and labor cost required by installation is reduced, and the installation efficiency of the tower body is improved.

Description

technical field [0001] The invention belongs to the technical field of tower group assembly, and more specifically relates to a split-type power tower group installation method. Background technique [0002] The transmission line tower group is a structure that supports the conductors and lightning protection lines of high-voltage or ultra-high-voltage overhead transmission lines. The transmission line tower group mainly bears wind load, ice load, line tension, constant load and the weight of personnel and tools during installation and maintenance. equal load. The number of transmission line towers is large, the distribution area is wide, and the natural conditions and terrain conditions are complex and changeable, which is not conducive to the use of large machinery for transportation and installation. [0003] The existing tower groups are usually installed in the way of holding poles, pulling wires or hoisting, but this way requires a large space and the cost of the enti...
