Abstract
The invention discloses a safety device for examining and repairing a tower, and relates to the safety device for aloft work on a power tower. The tower comprises a cross bar with a rectangular section, and consists of a hanging ring, a straight bar, a U-shaped clamping seat and a fastening screw, wherein an opening of the U-shaped clamping seat faces towards a side face; the distance between two side plates of the U-shaped clamping seat is slightly greater than the height of the cross bar; a corresponding wall plate close to the opening is provided with a pair of through holes which are coaxial with each other; the straight bar is inserted into the pair of through holes; axial positioning between the straight bar and the through holes on the clamping seat is realized by a positioning device; the fastening screw is tightly pressed against the cross bar inwards from the exterior of a bottom plate of the U-shaped clamping seat and is tightly pressed against the straight bar through the cross bar, so the cross bar, the straight bar and the clamping seat are fixedly connected with one another; and the hanging ring is fixedly connected to the top end of the straight bar. The safety device is suitable for the examining and repairing on the tower provided with the cross bar with the rectangular section, is convenient to carry, can be quickly and accurately arranged on the cross bar by one person, and then hooks a safety belt on the body of the person into the hanging ring for safety protection.
Description
Technical field
The present invention relates to a kind of safety device of work high above the ground, relate 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 present invention is directed to above problem, provide a kind of easy for installation, the safety device of the pylon maintenance that reliability is high.
Technical scheme of the present invention is: described pylon comprises that a cross section is the cross bar of 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; Offer the through hole of a pair of coaxial line on the approaching corresponding wallboard of described opening, described straight-bar inserts in this a pair of through hole, and realizes the axial location between through hole on straight-bar and the deck by positioner; Described trip bolt inwardly holds out against described cross bar by the outside of U-shaped deck base plate, holds out against described straight-bar by cross bar again, makes between cross bar, straight-bar and deck and fixedlys connected; Described suspension ring are fixedly connected on the top of straight-bar.
Described straight-bar bottom is provided with the step that is used for locating with the last through hole of described wallboard justifies, 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 present invention 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.
