Abstract
The utility model provides an overhauling bracket of a disconnector, relating to a safety device for aloft work on a power tower frame. The disconnector is arranged on the tower frame; the cross section of a transverse rod of the tower frame for supporting the disconnector is rectangular; the overhauling bracket consists of a suspension ring, a straight rod, a U-shaped clamping seat and a fastening bolt; an opening of the U-shaped clamp seat faces to the side surface; the distance between two side plates of the U-shaped clamping seat is slightly larger than the height of the transverse rod; a corresponding wall plate, which is near to the opening, is provided with a pair of holes; the straight rod is extended into the holes from an upper place; the distance between the straight rod and the bottom plate of the U-shaped clamping seat is slightly larger than the width of the transverse rod; the fastening bolt inwards and tightly supports the transverse rod from the outer part of the bottom plate of the U-shaped clamping seat; and the suspension ring is fixedly connected on the top end of the straight rod. The overhauling bracket is applicable to overhauling on the tower frame with the rectangular cross section; the U-shaped clamping seat and the straight rod which are transversely arranged can be conveniently carried with workers to the tower, so that one worker can fast and exactly install the U-shaped clamping seat and the straight rod on the transverse rod; and safe belt hooks on the workers can be suspended in the suspension ring immediately, thereby playing a part in safety protection.
Description
Technical field
The utility model relates to a kind of safety device of work high above the ground, relates in particular to the safety device that carries out work high above the ground on the electric tower.
Background technology
The isolating switch maintenance is that we are engaged in an important content of working in the substation equipment maintenance and repair, belong to the work high above the ground category, for effectively preventing the generation of personal injury and equipment breakdown, we adopt safety belt is directly tied up on the isolating switch support insulator in maintenance such as high voltage isolator in the past, but with in " the electric power safety working regulation " newly issued in June, 2005 about " use of safety belt is stipulated again in the high-rise working; " safety belt must not hang down and hang high using, forbid being to hang on the isolating switch supporter, should hang on the firm member or aim on the steelframe that hanging safety belt uses " the isotactic phasing conflicts; and we in time improve the method to set up of above-mentioned safety measure, and adopting the herringbone insulating ladder is to tie up safety belt.The method has met the rules requirement by the application of one-year age nearly though find the use of safety belt, and consuming time, effort has increased the workload that isolating switch overhauls greatly.
Though the method has met the requirement of rules defineds, in isolating switch maintenance, used a period of time after, we have still found many problems.With a GW4-110 type isolating switch maintenance is example, and we maintainer overhauled this type isolating switch in the past, needs 4 maintainers earlier double ladder to be carried to the working site, when carrying out service work, need 1 maintainer, 2 people help, and 1 people transmits the Work tool that inspection and repair shop needs.In addition, because of being subjected to the restriction of space for maintenance, an isolating switch has 3 phases, 6 contacts, needs mobile double ladder 6 times at least, just can finish the service work of an isolating switch.Need 4 maintainers to cooperate around here altogether, the time of wherein installing safety measure and being spent accounts for about 1/3 of the major overhaul time, expends more human and material resources.
The flow process of safety devices device is as follows during the isolating switch maintenance: 4 people are carried to the working site with double ladder and set up; 2 people help, and 1 people climbs up and fastens seat belts and work, and 1 people transmits object; An isolation switch contact maintenance is finished, and behind the Awaiting Overhaul personnel descending stair, 4 people adjust the ladder position; 4 people move away from the working site with double ladder behind the end-of-job; Finish.Find out thus, adopt double ladder to fasten the safety belt and carry out the method for isolating switch maintenance that can not improve the operating efficiency of maintenance really, the human and material resources that spent have accounted for very big ratio in the cost of overhaul.
Summary of the invention
The utility model provides a kind of easy for installation at above problem, the isolating switch maintenance support that reliability is high.
The technical solution of the utility model is: described isolating switch is installed on the pylon, and the cross bar cross section of described pylon carrying isolating switch is a rectangle, and it is made of suspension ring, straight-bar, U-shaped deck and trip bolt; Described U-shaped deck opening is towards the side, and distance is slightly larger than the height of described cross bar between U-shaped deck biside plate; Offering pair of holes near on the corresponding wallboard of described opening, described straight-bar stretches in the hole from the top, and spacing is slightly larger than the width of described cross bar between straight-bar and U-shaped deck base plate; Described trip bolt inwardly holds out against described cross bar by the outside of U-shaped deck base plate; Described suspension ring are fixedly connected on the top of straight-bar.
Described straight-bar bottom is provided with the step circle that is used for location, described hole, and the distance of described step distance of round straight-bar bottom is slightly larger than the width of described U-shaped deck.
Described straight-bar bottom is provided with the radial direction through hole that is used to be provided with split pin.
The utility model is applicable to when overhauling and uses that horizontal U-shaped deck, straight-bar can carry tower by personnel easily on the pylon with square-section cross bar, a people can attach it on the cross bar quickly and accurately; Be suspended in the suspension ring with being about to personnel's safety strap hook on one's body, play the effect of security protection.
