Abstract

The invention discloses a line stringing tightening mechanism for capital construction engineering. The line stringing tightening mechanism comprises a rack, a line pulling device, a warning device, aquick adjustment device, a fine adjustment device and a tightening device. The quick adjusting device, the fine adjusting device and the tightening device are connected through a transmission shaft,and the transmission shaft is rotationally fixed to the rack. A pull rope is wound on the tightening device, the stringing tightening speed can be slowly adjusted by the fine adjustment device throughgear transmission, and the stringing tightening speed can be quickly adjusted by the quick adjustment device through gear transmission. The wire pulling device comprises a pull hook and a pull rod, alimiting cavity is formed in the pull rod, a sliding block, a connecting rod and a compression spring are arranged in the limiting cavity, one end of the connecting rod is fixed to the sliding block,the other end of the connecting rod penetrates through the side wall of the pull rod to be fixed to the pull rope, the connecting rod is sleeved with the compression spring, the upper portion of thesliding block penetrates out of the limiting cavity and is connected with the warning device through the sliding rod, and the movement of the sliding rod can make the warning device rotate. The mechanism can accurately judge that the stringing is just tensioned, the service life of the stringing is prolonged, and the stringing tightening efficiency is improved.

Description

technical field [0001] The invention belongs to the field of wiring for infrastructure projects, and relates to a line stringing tightening mechanism for infrastructure projects. Background technique [0002] When laying lines in infrastructure projects, it is necessary to tighten the overhead lines. During the use of the current stringing tightening device, the construction personnel cannot accurately judge whether the line is just tightened. Once the stringing wire is pulled too tightly, it is easy to be pulled, which reduces the service life of the stringing wire. In addition, the existing stringing tightening device has a slow tightening speed in the process of tightening the stringing, the tightening speed is low, and the practicability is poor. Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a line stringing tightening mechanism for infrastructure projects, which can accurately jud...
