Description
Technical field
The utility model relates to a kind of pick-up unit of power construction seat belt hanger, belong to the safety detection technology field of power construction equipment.
Background technology
In the various accidents of electric system, falling accident is one of current topmost casualty accident.Therefore, ensureing the safety of high-rise working workmen, is the most important thing of safety in production.
In " State Grid Corporation of China's electric power safety working regulation ", (be called for short " safety " below), have corresponding strict regulations to high-rise working:
1) all operations carried out at height of fall reference field 2m and above eminence, all should regard as high-rise working ";
2) there is no framing scaffold or working not having on parapeted framing scaffold, time highly more than 1.5m, should use of seat belts, or take other reliable safety practices;
3) securing band should adopt the mode that high extension is low;
4) forbid be to hang on mobile or unstable object [as disconnector (disconnecting link) support insulator, porcelain pole arm, without fixing rotation cross-arm, circuit support insulator, lightning arrester support insulator etc.];
5) installation of framing scaffold, dismounting and use, should perform the relevant regulations stipulate of relevant regulations and country in " safety ".
From the above-mentioned relevant provision in " safety ", plug-in strip nearly all in transformer station, switch, circuit installation and maintenance work, be considered as high-rise working all.And wherein have more work, just can may complete in 1 to several hours, if adopt the mode of scaffolding to carry out work, when not only taking a lot of work, and will through operations such as loaded down with trivial details installation, examination, use, dismountings, careless slightly, just can bring new potential safety hazard; And the places such as plug-in strip, switch, circuit cross-arm lack the component that can supply firmly to hang securing band.Therefore, a kind of novel seat belt hanger arises at the historic moment, and formal name is fixed on single equipment pedestal during " single column inspection platform "-station, for hanging the pillar falling proof device (see figure 1) of securing band or safety catcher.
Since the nearly section time, the various seat belt hanger of domestic production, quality is very different, only has the test of strict science in addition, just can prevent the generation of security incident.
To the detection of single column inspection platform, main exist following difficulty:
