The invention aims at providing a tension pay-off pulley, which comprises a rim, a rotating wheel assembly and an installation plate assembly, wherein the rim comprises an outer ring and an inner ring provided with wheel teeth; the outer ring is provided with a guide groove through which a guide wire passes; the outer wall of the guide groove is provided with a round limiting groove symmetrical about the guide groove; the rotating wheel assembly comprises a bearing wheel in the middle and two driving wheels; the two driving wheels are symmetrically arranged at two sides of the bearing wheel and are meshed with the wheel teeth; the installation plate assembly comprises a pair of fixed plates which is symmetrically arranged at two sides of the rotating wheel assembly; installation shafts of the bearing wheel and the driving wheels all are parallel to one another; the end parts, located on the same side, of the installation shafts all are fixedly connected to the same fixed plate; and a plurality of limiting idler wheels are evenly distributed on each fixed plate and are inserted into the limiting groove. The structure is novel; the components of a spoke plate, a main driving shaft, a carrier bearing and the like of a traditional pulley are omitted; the lengths of support frames at two sides of the pulley are reduced; and the overall weight of the pulley can be significantly reduced.
Description
technical field [0001] The invention belongs to the technical field of power transmission line stringing equipment, and in particular relates to a tension pay-off pulley. Background technique [0002] At present, in the construction of power transmission lines, nylon rubber tackles are often used when laying out the wires, and large-tonnage cast steel rubber tackles are used when turning. Substantial increase, construction laying out transportation and on-site handling and installation are more difficult. Contents of the invention [0003] The object of the present invention is a tension pay-off tackle with a novel structure, which saves components such as the spoke plate, main drive shaft and bearing bearing of the traditional tackle, and reduces the length of the supporting frames on both sides of the tackle, which can significantly reduce the overall weight of the tackle. Lightweight, easy to install on the construction site. [0004] The present invention adopts foll...
