Embodiment Construction

[0021] The embodiment of pay-off block among the present invention is such as Figure 5~7 As shown: including a lifting mechanism, the lifting mechanism includes a reel 10 driven by a geared motor. When in use, the reel needs to be installed on the iron tower, and the front side stay rope 11 and the back side stay rope 12 of synchronous lifting action are wound on the reel. The front side stay cord 11 and the rear side stay cord 12 constitute the action output end of the hoisting mechanism, and the action output end is connected with a tackle bracket, and the tackle bracket is provided with an unwinding mechanism, and the tackle bracket includes a left side bracket plate 13 and a right side bracket plate 14, the pay-off mechanism also includes a front-side first pay-off rolling body 15 and a rear-side second pay-off rolling body 20 arranged at intervals between the left side bracket plate and the right side bracket plate, and the front side first The rotation axes of the pay-o...

Abstract

The invention relates to a pay-off pulley, a pulley support, a pay-off mechanism arranged on the pulley support, the pay-off mechanism comprising at least three rotating axes extending along the left and right directions for the pay-off rolls arranged in the circumferential sequence during the pay-off process Each pay-off rolling body has an outer rolling surface for contacting and rolling with the corresponding split wire. The invention adopts the form of a plurality of pay-off rolling bodies distributed in the circumferential direction to replace the large-diameter pulley in the prior art, which ensures that the split wire has a large bending radius when passing through, and also saves the space on the lower side of the pay-off pulley. , reducing the structural size of the product.

Description

technical field [0001] The invention relates to a pay-off pulley in the field of wire tower erection. Background technique [0002] The existing iron tower wiring structure such as Figure 1~2 As shown, an insulator string 1 is suspended on the iron tower, and the lower end of the insulator string 1 is connected to a connecting plate 2, and a plurality of suspension clamps 4 are connected to the connecting plate 2 through bolts 3, and each split wire 5 is respectively connected to the corresponding suspension clamps. 4 connected. [0003] The pay-off process of the split wire is as follows: Figure 3~4 As shown, first connect the pay-off pulley 7 on the insulator string 1, after the split conductor 5 is released through the pulley 8 on the pay-off tackle, the corresponding split conductor 5 is hooked by the lifting mechanism 6, and the height of the split conductor is raised , then connect the suspension wire clamp 4 at the corresponding position of the split wire, the lif...
