Paying off pulley apparatus

Abstract

The invention discloses a paying off pulley apparatus. The apparatus comprises a pedestal. The pedestal is provided with a support. A top of the support is provided with a pulley in a fixed-axis rotation mode. An axis of the pulley is consistent with a horizontal direction. A central section of the pedestal is provided with an adjusting component. The adjusting component possesses a long hole which is extended along a vertical direction. An adjusting bolt which is cooperated with the long hole passes through the pedestal. The adjusting bolt moves properly along a length direction of the long hole and moves the support along the vertical direction so as to adjust a height of the pulley to be a proper position. During a subsequent paying off process, a traction output direction of a cable and correlation facilities of a cable well and the like do not generate a structure interference. When adjustment is enough, the adjusting bolt is locked so as to ensure that a relative position of the support and the pedestal is locked and then ensure that position stabilization of the pulley and the cable during the paying off process. By using the paying off pulley apparatus, a whole paying off process is stable and high-efficient, the cable does not generate friction or other structure interferences with correlation construction equipment and the cable is guaranteed not to be damaged during the paying off process.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for power transmission and transformation equipment, in particular to a wire-releasing pulley device. Background technique [0002] During the laying construction process of general power transmission and transformation lines, a pay-off pulley device is usually used to pull and lay cables. [0003] In the prior art, the pay-off pulley device is usually directly installed in the cable wells of the line construction, etc., but limited by the structure of the existing pay-off pulley device itself, the height specification of the pay-off pulley device must be fixed during the pay-off process. , When the construction process is not standardized or the working environment is relatively special, it is easy to cause frequent non-working contact between the cable and the cable well or manhole cover and other related working surfaces, resulting in damage to the cable and seriously affecting the...
