Description
Technical Field
The invention relates to a power equipment maintenance device, in particular to a safety belt suspension device for maintenance of an isolating switch.
Background
GW4 type and GW5 type disconnecting switches are widely applied to substations, GW4 type disconnecting switches are mainly used for 10kV, 35kV and 110kV systems, GW5 type disconnecting switches are mainly used for 35kV, 66kV and 110kV systems, and various defects may occur after the disconnecting switch equipment runs for a long time and need to be overhauled. According to the regulation of national grid company electric safety work regulations, when the height of the safety belt works on a scaffold without a scaffold or a scaffold without a railing and exceeds 1.5m, a safety belt is used, a hook or a rope of the safety belt is hung on a firm component or a steel wire rope specially used for hanging the safety belt, and a mode of hanging the safety belt at a high position and hanging the safety belt at a low position is adopted.
In the maintenance process, in order to ensure the safety of the operating personnel, a hanger is usually required to be installed for fixing a safety belt. In the single-phase maintenance work, a seat belt hanger is generally provided on a frame channel on the side of a defective phase, and as shown in fig. 1, a seat belt hook is hung on a hanging ring at the upper end of the hanger, taking a GW5 type isolating switch as an example. When two-phase or three-phase maintenance operation is carried out, the personal safety of a maintainer is considered, the length of the safety belt is limited, and two hangers are generally required to be matched for use, namely, a hanger (called a hanger I) is installed on a framework channel steel between an A phase and a B phase and used for completing the operation of the A phase or the B phase, then a hanger (called a hanger II) is installed on the framework channel steel between the B phase and the C phase and used for completing the maintenance operation of the B phase or the C phase, for example, a GW5 type isolating switch is still taken as an example, as shown in figure 2, when the maintainer shifts from the position of the hanger I to the position of the hanger II in work, the safety belt needs to be taken down from the hanger ring I and moved to the position between the B phase and the C phase, then the safety belt is hung on the hanger ring II, and in the process, the maintainer can lose safety protection temporarily; when the hanger is transferred from the position of the hanger II to the position of the hanger I, no safety protection measures are taken. As can be seen from fig. 1 and 2, the structure of the isolating switch determines that the movable space at the upper part of the framework is very limited, so that when the maintainers transfer the operation position, the disconnecting switch is easy to trip, and the high-altitude falling accident is very easy to cause under the condition that no safety protection measures or incomplete safety protection measures exist, so that great potential safety hazards exist.
At present, a safety belt hanging device for overhauling high-safety isolating switches with various voltage levels of GW4 type and GW5 type does not exist, how to guarantee the personal safety of operating personnel is an urgent safety requirement in the field of overhauling of GW4 type and GW5 type isolating switches.
Chinese patent No. CN201862167U discloses a suspension frame for maintenance of safety belt of isolating switch, which comprises a pair of fixing clip bodies formed by connecting an upper clip plate and a lower clip plate through a connecting bolt, wherein screw thread connecting seats are respectively arranged on the upper clip plate of each fixing clip body, vertical upright posts are connected through screw thread connecting seats, a cross bar for assembling a safety belt suspension ring is arranged between the two upright posts, and open bolt fastening clamps connected with the upright posts are respectively arranged at two ends of the cross bar. However, the safety risk that the fixing clamp body and the channel steel are not firmly clamped exists in the safety belt hanging frame, and meanwhile, the application limitation of the safety belt hanging frame is large due to the fact that the length of the cross rod is not adjustable.
Notice No. CN206934480U discloses a 110kV isolator overhauls safety belt linkage, including two unable adjustment bases, two hack levers and safety belt suspension rope, two hack levers are adorned admittedly respectively on two unable adjustment bases, safety belt suspension rope both ends connect respectively in two hack lever tops, its characterized in that: the safety belt hanger comprises a frame rod, and is characterized in that a tension bolt is installed at the top of the frame rod, a fastening device is installed at one end of the tension bolt, and a safety belt hanging rope is connected with the fastening device. However, when the suspension rope adopted by the safety belt suspension device is stressed, the left frame rod and the right frame rod are easy to contract towards the middle, so that the suspension device loses the protection effect, and the safety is not high enough.
