Embodiment Construction

[0020] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0021] A method for accurately laying out the initial lead rope of a transmission line ground wire into a pulley groove, characterized in that: the steps of the method are:

[0022] 1) Installation of the reserved connection rope at the top of the tower: after the iron tower 1 is assembled, while hanging the porcelain vase 3, fix the two ends of the reserved connection rope 2 at the top of the tower to the lower end of the porcelain vase;

[0023] 2) Installation and transportation of the connecting rope reserved for the pulley: Before lifting the pulley 7 on the ground, bundle the initial rope fixed groove rope 9 on the middle pulley 10, fix the end of the fixed groove rope on the pulley spoke 11 of the edge pulley, and pre-install the pulle...

Abstract

The invention relates to a method for accurately setting out the initial lead rope of a power transmission line into a pulley groove, characterized in that: the steps of the method are: 1) installation of the connecting rope reserved on the top of the tower; 2) installation of the reserved rope of the pulley 3) Installation of the reserved rope; 4) The initial lead rope enters the inner groove of the pulley. The present invention has scientific and reasonable design, simple operation, and personnel do not need to manually operate on the block for the initial lead rope to pass through the block, which saves labor costs, significantly improves construction safety, and the initial lead rope is evenly stressed and can be used repeatedly. Safe, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of construction operation of transmission lines, relates to the construction of primary ropes for the construction of transmission lines, and in particular to a method for accurately setting out the primary ropes of the grounding wires of transmission lines into pulley grooves. Background technique [0002] At present, in the construction and setting out of power transmission lines, it is a common construction method to use the initial guide rope of the artificial tower and the electric aircraft to release the ground wire. In these methods, the initial guide rope cannot directly pass through each block, and must be used Manually stand on the pulley to complete the process of threading the rope. It is also a problem that the initial rope enters the pulley groove. It cannot realize continuous pay-off in the true sense, which increases safety hazards and requires labor. The currently commonly used "wrapping met...
