Abstract
The utility model provides a primary device overhaul falling protector fixing rack of a transformer substation and aims at solving the fixing problem of a falling protector during primary device overhaul in the transformer substation. The primary device overhaul falling protector fixing rack is of a channel steel structure and is matched with a monopole rack of a primary device in the transformer substation through a U-shaped bolt assembly, wherein mounting holes matched with two ends of the U-shaped bolt assembly are formed in the channel steel bottom face. The primary device overhaul falling protector fixing rack is characterized in that the mounting holes are of long-hole structures, one long hole is an opened long hole, and the other long hole is the mounting hole for a connecting structure of a large-diameter round hole and a small-diameter long hole. The primary device overhaul falling protector fixing rack is simple in structure and convenient to dismount, ensures the construction safety of operation workers and improves the overhaul work efficiency of electric power facilities.
Description
Technical field
The utility model relates to a kind of high-lift operation fall-preventing device support, and especially a kind of transforming plant primary equipment maintenance fall-preventing device fixing frame that the one pole framework is supported that is applicable to belongs to generating, power transformation or distribution technique field.
Background technique
In the electric power facility maintenance process, often run into various challenges, and these problems can impact maintenance progress and operator's personal safety, such as when the isolation switch that the one pole framework is supported overhauls, owing to do not have the fall-preventing device immovable point on the framework, make the maintainer can't carry out proper functioning.Though adopt the one pole framework maintenance fall-preventing device fixing frame of on-the-spot disassembly and assembly structure to solve the fixation problem of fall-preventing device, but because the U bolt pilot hole 1-1 on this one pole framework maintenance fall-preventing device fixing frame 1 is borehole structure (referring to accompanying drawing 1), U bolt pilot hole and U bolt two ends quality of fit are had relatively high expectations, make the dismounting of fall-preventing device fixing frame bother very much, approximately need 8 fens clock times just can finish the disassemble and assemble work of fall-preventing device fixing frame, working efficiency is lower.
The model utility content
The purpose of this utility model is the drawback at prior art, a kind of simple in structure, easy accessibility is provided, can guarantees operator's construction safety, is conducive to the transforming plant primary equipment maintenance fall-preventing device fixing frame of increasing work efficiency again.
Problem described in the utility model realizes with following technical proposals:
A kind of transforming plant primary equipment maintenance fall-preventing device fixing frame, it is the channel-section steel structure, one pole framework by U bolt assembly and transforming plant primary equipment is equipped, be provided with two pilot holes that mate with U bolt in the channel-section steel bottom surface, its specialization is: described pilot hole is the slotted hole structure, one of them slotted hole is the open type slotted hole, and another slotted hole is the pilot hole of major diameter circular hole and small diameter long hole connection structure.
Above-mentioned transforming plant primary equipment maintenance fall-preventing device fixing frame, described open type slotted hole is positioned at the front end of channel-section steel bottom surface, and the pilot hole of described major diameter circular hole and small diameter long hole connection structure is positioned at the middle part of channel-section steel bottom surface.
Above-mentioned transforming plant primary equipment maintenance fall-preventing device fixing frame is installed the fall-preventing device fixed base, described fall-preventing device fixed base and fall-preventing device coupling in its back-end.
The utility model improves design on the one pole framework fall-preventing device fixing frame basis of original on-the-spot disassembly and assembly structure, it changes the U bolt pilot hole on the channel-section steel bottom surface into the slotted hole structure, the pilot hole that wherein is positioned at the utility model fall-preventing device fixing frame front end is the open type slotted hole, the pilot hole that is positioned at the utility model fall-preventing device fixing frame middle part is major diameter circular hole and small diameter long hole connection structure, like this when the U bolt assembly assembles, can earlier assembling end before the U bolt be inserted the opening of opening slotted hole, assemble behind the U bolt and correct in the major diameter circular hole that inserts the fixing frame middle part this moment; Then with the sliding backward of the utility model fall-preventing device fixing frame, enter the end of minor diameter slotted hole until the back assembling end of U bolt; By bolt fastener the two ends of U bolt are fixed at last, finished the assembling of the utility model fall-preventing device fixing frame and transforming plant primary equipment one pole framework.The utility model is simple in structure, easy accessibility, both guaranteed operator's construction safety, has improved the working efficiency of electric power facility maintenance again.
