Problems solved by technology
At present, the general transmission method is to use a rope buckle and a steel wire sleeve to suspend the transmission block below the insulator (see figure 1 ), this construction method has a low hanging point of the transfer rope, and requires the operators on the line to lean over and tilt, and lift laboriously to complete the tool transfer, which increases the labor intensity of the online operators, and the work efficiency is low, accompanied by high Whether it is the personal safety of the operators or the proper use of tools, it is difficult to guarantee the operation risks, and it may even delay the maintenance of the transmission line, resulting in major economic losses.

The invention provides a transmission line insulator string maintenance pass pulley which is characterized in that the transmission line insulator string maintenance pass pulley is formed by the buckle connection of a semi-circular upper clamping ring (5) and a semi-circular lower clamping ring (7) (in figure 4), one end is hinged by using a pin shaft (6), the other end is connected to a nut (11) by using a T screw (10), and thus a T screw connection end can be tightened or loosened. The transmission line insulator string maintenance pass pulley has the advantages that the pass pulley can be fixedly mounted on an insulator steel cap easily and stably, the operation is simple, the disassembly is easy, the safety factor of a high attitude working is improved, the tool lifting distance by an operator is shortened or even eliminated, the labor intensity is reduced, the work efficiency is improved, the pulley hanging point pass limit is broken, the pass pulley is light, flexible, safe and reliable, the overall weight is small, and the pass pulley is convenient to carry.
Description
technical field [0001] The invention belongs to an auxiliary tool for overhauling a high-voltage transmission line, and relates to a tool for transferring tools and appliances used to high altitude during the overhauling of an insulator string of a transmission line. Background technique [0002] The maintenance work of the transmission line is completed at high altitude, and there are many kinds of line maintenance tools. During the maintenance, these maintenance tools need to be passed to the high altitude. At present, the general transmission method is to use a rope buckle and a steel wire sleeve to suspend the transmission block below the insulator (see figure 1 ), this construction method has a low hanging point of the transfer rope, and requires the operators on the line to lean over and tilt, and lift laboriously to complete the tool transfer, which increases the labor intensity of the online operators, and the work efficiency is low, accompanied by high Whether it i...
