Problems solved by technology
[0004] The disadvantages of this structure are: 1. The main material replacement support frame and the tower correction bracket are of high quality and difficult to transport
2. The main material replacement support frame is bulky and not easy to carry
3. There are gears for the length adjustment of the main material replacement support frame. If the length to be adjusted is between the two gears, the installation of the main material replacement support frame will be laborious, and the main material replacement support frame will be stressed after installation. In the process, it is easy to break and cause an accident
4. When the ground is uneven, the tower correction bracket is tilted, and it is difficult to correct the transmission line tower

A principal material replacing support assembly of an electric transmission line tower comprises a principal material replacing supporting frame and a tower straightening support. The principal material replacing support assembly is characterized in that the principal material replacing supporting frame is provided with a first lead screw, a first handle is fixedly connected to the first lead screw, casing pipes are connected to the two sides of the first lead screw through threads, and the casing pipes are fixedly and respectively connected with a connecting vertical board. Two supporting rods are arranged on the tower straightening support, one end of one supporting rod is connected with one end of the other supporting rod through a cardan joint, the cardan joint is provided with a connection transverse board, the other end of each supporting rod is connected with a second lead screw through a thread, a second handle is fixedly connected to each second lead screw, and the lower ends of the second lead screws are respectively connected with a base through threads. The principal material replacing support assembly of the electric transmission line tower has the advantages of being light in mass, convenient to transport, small in size, convenient to carry, high in adjusting precision, good in safety performance, and suitable for different terrain conditions.
Description
technical field [0001] The invention relates to a support assembly for replacing the main material of a power transmission line tower. Background technique [0002] After a long time of use, the transmission line tower will tilt. If it cannot be corrected in time, it will cause the tower to topple, cause a safety accident, and cause a large-scale and long-term power outage, causing losses to people's property. In addition, when a main material component on the transmission line tower is damaged, it must be replaced. The component cannot play a supporting role during the replacement, which will also lead to the occurrence of the tower toppling accident. [0003] The existing power transmission line tower main material replacement support assembly includes two parts, respectively the main material replacement support frame and the pole tower correction support. Wherein the main material replacement bracket is composed of a telescopic rod and connectors affixed to both ends of...
