Overhead power transmission line laying device

Abstract

The invention discloses an overhead power transmission line laying device composed of a line laying table and a line laying frame. The line laying table is formed by a pedestal, a strand frame, a wire wheel group, and a driving mechanism. The upper surface of the pedestal is connected with the strand frame, the wire wheel group, and the driving mechanism. The driving mechanism is formed by a positioning board, a driving motor, a transmission device, and a driving wheel. The driving motor, the transmission device, and the driving wheel are all installed on the positioning board. The wire wheel group is composed of a frame and at least two wire-pressing wheels installed on the frame and distributed oppositely. The line laying frame is composed of a frame body, a positioning clamp, a line laying clamp, a hauling cable, a guiding wheel, a rope strand wheel, and a driving device. The frame body is a rectangular structure formed by sidewalls and a base plate. The overhead power transmission line laying device may hoist heavy cables, such as power cables, steel strand wires and the like from ground to an assigned height of a power transmission pole, may extend the laid cables, and assures the laid power cables of good sag degrees and tension force.

Description

technical field [0001] The invention relates to an online device for a suspended transmission line, which belongs to the field of transmission line erection tools and equipment. Background technique [0002] With the requirement of long-distance power transmission, a large number of high-voltage transmission lines need to be suspended and erected through power poles and towers. Due to the lack of professional construction equipment, in traditional construction, it is often necessary to use large-scale hoisting engineering machinery, or rely on construction personnel to manually lift it, resulting in high construction costs and low construction efficiency in traditional construction. In addition, personal and equipment injury accidents occur. At the same time, due to the heavy weight of the power cable, after it is suspended in the air, it will cause serious sagging due to its own weight, resulting in the distance between the power cable and the ground being less than the nat...

[0002] With the requirement of long-distance power transmission, a large number of high-voltage transmission lines need to be suspended and erected through power poles and towers. Due to the lack of professional construction equipment, in traditional construction, it is often necessary to use large-scale hoisting engineering machinery, or rely on construction personnel to manually lift it, resulting in high construction costs and low construction efficiency in traditional construction. In addition, personal and equipment injury accidents occur. At the same time, due to the heavy weight of the power cable, after it is suspended in the air, it will cause serious sagging due to its own weight, resulting in the distance between the power cable and the ground being less than the national safety regulations. At present, there is no professional response equipment in construction, and construction still needs to be carried out by manpower or large-scale construction machinery or vehicles. As a result, on the one hand, the construction cost is high, the construction efficiency is low, and personal and equipment injury accidents occur. It is also impossible to accurately and effectively ensure the accuracy of the power cable when adjusting the sagging height, resulting in poor construction quality and threatening the safety of electricity use
