Abstract

The invention belongs to the technical field of cable mounting equipment, and particularly relates to a cable erecting device capable of compensating tension, which comprises a telegraph pole, a compensating device and an air inlet and outlet regulating valve group. Cross arms are symmetrically arranged on the telegraph pole, and the compensation devices are installed at the bottoms of the cross arms. The compensation device comprises a clamp, a fixing pipe and a side auxiliary pipe. The bottom of the clamp is provided with a notch used for placing a cable. And a mounting seat is arranged at the top end of the fixed pipe and is fixed below the cross arm. A main telescopic rod is movably inserted into the fixing pipe, and the bottom end of the main telescopic rod is rotationally installed in the middle of the top of the clamp. The device is erecting equipment which is designed for solving the problem of tension fluctuation in the cable erecting process and can dynamically compensate tension, and self-adaptive tension adjustment of the cable under the working conditions of wind disturbance, temperature deformation, load fluctuation and the like is achieved through a composite structure of mechanical elastic compensation and gas energy absorption assistance. The overall structure of the device is modularized, installation is convenient, and adjustment is flexible.
