A method of auxiliary trolley for overhead busbar hoisting

Abstract

The invention provides an auxiliary trolley for overhead busbar hoisting. The trolley comprises a base, at least two pulleys, supporting arms used for fixing the pulleys, limiting plates and clamping arms fixed to the lower end of the base, wherein the supporting arms are arranged at the upper end of the base, each pulley is installed between the two corresponding supporting arms, the limiting plates are connected with the outer sides of the supporting arms and located on the two sides of each pulley, the top ends of the limiting plates are higher than the top ends of the circumferential surfaces of the round wheels of the pulleys, and the line connecting the clamping arms is parallel to the line connecting the top ends of the pulleys. The trolley is safe, reliable, highly practical and capable of improving construction efficiency. The trolley can be applied to different types of frameworks for flexible busbar hoisting, is capable of achieving one-step hooking and effectively avoiding the contact and friction between a drag rope and the frameworks during hoisting, can not cause potential safety hazards of high-altitude falling on aerial working staff and equipment below, and can be widely popularized in high-voltage and ultrahigh-voltage transformer stations.

Description

technical field [0001] The invention relates to an auxiliary device for electric power construction, in particular to a method for an auxiliary trolley hoisting a busbar (especially a soft busbar). Background technique [0002] In the process of electric power construction, the construction of busbar (especially soft busbar) is an important project of substation electrical installation engineering, and its quality and safety process control has always been the focus and difficulty of installation management. Especially for large-scale high-voltage or ultra-high-voltage substations, as the voltage level increases, the safety distance between the equipment and the frame increases exponentially, and the height and span of the soft busbar hoisting also increase continuously, so the difficulty of hoisting increases. At the same time, the hidden dangers of construction and the quality risks of construction will continue to increase. [0003] According to the traditional hoisting ...

AI Technical Summary

Problems solved by technology

This kind of construction process not only has risks in the suspension mode of the fixed pulley and the quality of the fixed pulley itself, but also the suspended fixed pulley will easily swing during the construction process, making it difficult to realize the fitting ring 9 and the mounting plate 10 on the beam. The butt joint faces of the flexible busbar 11 need to be shaken several times or adjusted by pressing the relative positions of the fitting ring 9 and the articulated plate 10 to complete the hoisting of the soft busbar 11, which not only takes time and effort, but also reduces the construction cost efficiency, and adds an additional safety risk to workers working at heights

Moreover, during the construction process, there is friction between the traction rope 7 and the frame, and the long-term construction causes the traction rope to wear and tear, which also increases the safety hazards of construction.
