Transmission line iron tower pile wire releasing device and its construction method

Abstract

The invention discloses a paying-off device for an iron tower pile of a transmission line and a construction method of the paying-off device. The paying-off device comprises a bottom plate. Dovetail grooves are formed in the bottom plate. Supporting plates are installed on the bottom plate in the manner that bottom connecting pieces are clamped into the dovetail grooves. The paying-off device is characterized in that pin clamps are installed on the supporting plates, and first connecting rods, second connecting rods and third connecting rods form triangular frames to be installed on the supporting plates; a shaft bracket is installed at the joint of each first connecting rod and the corresponding second connecting rod; and the bottom of each second connecting rod is provided with a fourth pin which penetrates in the corresponding supporting plate; and each first connecting rod is connected with the corresponding third connecting rod through a second pin, and each third connecting rod penetrates in the corresponding pin clamp to be fixed through an adjusting pin. The paying-off device has the beneficial effects that the paying-off device is fixed to a transportation vehicle and is driven by the vehicle to move forwards to conduct paying-off; a coiling cylinder is convenient to demount, little labor force is needed, and the wire outlet speed of the device is high; and wire outlet circuits are not twined with one another, and the paying-off device is suitable for being used and popularized.

Description

technical field [0001] The invention relates to a power grid construction device, in particular to a power transmission line iron tower pile wire releasing device and a construction method thereof, which belong to the technical field of electric power construction. Background technique [0002] Electric power engineering refers to engineering related to the production, transmission, and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. The bubbling area is composed of angle steels juxtaposed with each other, and the arrangement direction of the angle steels is parallel to the direction of liquid flow. The sharp edge of the angle steel of the tower pile is at the lower part, and the cross section is "V" shaped. There is a certain gap between two adjacent angle steels, and the downcomer is the same as the general tower plate. The liquid on the previous plate flows into the "V"-shaped an...

AI Technical Summary

Problems solved by technology

[0005] At present, the line erection work between the tower piles of the transmission line is too heavy. Due to the relatively thick diameter and heavy weight of the high-voltage line, it is necessary to manually push the reel forward during the erection process, and it is also necessary to manually tighten it when tightening it, and the speed is slow. , the workload of construction workers is heavy

At the same time, when the wires are coming out, it is difficult to arrange the wires due to the heavy weight of the reel
