Disconnecting switch overhauls anti-fall device

Technical field

The utility model is related to electric power overhaul field, more particularly to a kind of disconnecting switch maintenance anti-fall device.

Background technology

Disconnecting switch (abbreviation plug-in strip) runs that quantity is more in electric substation, and maintenance workload is big.When plug-in strip maintenance is carried out, Due to maintenance craft requirement, maintainer must carry out the service work of correlation on plug-in strip framework.《Electric power safety work rule Journey》Specified altitude difference is in 2m or more work sites, it is necessary to use of seat belts, and its use requirement is " height hangs low use ".And In the maintenance process of reality, due to without special hanging rack for safety belt is overhauled, so in maintenance, as used, " ladder is ascended a height, specially People helps " or after ladder is leaned against on plug-in strip, it is necessary to the side of the upper equipment of staff after first terraced string for binding a plait is fixed in equipment Formula, need frequently up and down or move ladder when place is converted in maintenance engineering, directly affect service work efficiency.And maintainer Directly when being worked on plug-in strip framework, then need not frequently up and down or mobile ladder, but due on plug-in strip without safety belt Hanging point, and maintainer when plug-in strip maintenance or debugging is carried out, it is necessary to three-phase fracture is moved, and the height of plug-in strip is equal More than two meters, according to《Electric power safety working regulation》Regulation, during work, it is necessary to use of seat belts.Therefore in present case Under, safety belt can tied up to and be operated on porcelain knob by maintainer in violation of rules and regulations, so as to cause porcelain knob damaged or be broken.If will Safety belt is hung on the operator link of plug-in strip, and the principle of " height hangs low use " is not met again, and maintainer moves between phase and phase When, can frequently dismount safety belt hanging point.If the fall impulsive force of generation of therefore slipping can bring injury to the person.While human body The acceleration of gravity for falling can cause the deformation of operator link.

It is therefore desirable to a kind of disconnecting switch maintenance anti-fall device, effectively improves staff aloft to disconnecting switch The security overhauled.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of disconnecting switch maintenance anti-fall device, effectively improves work Make the security that personnel are aloft overhauled to disconnecting switch.

Disconnecting switch of the present utility model overhauls anti-fall device, including framework platform and the safety that is connected on framework platform Bearing plate with fixed support and for supporting human body；The safety belt fixed support includes base and bumper；The insurance Thick stick includes overcoat and the coaxial interior bar being located in overcoat, and the interior bar can be along the axial movement of overcoat and solid by location structure Fixed, the interior bar is provided with the hook auxiliary section for coordinating with seat belt hanger；The overcoat is connected to framework by base Platform.

Further, the bottom of the overcoat rotates connected mode and is connected with base with single-degree-of-freedom.

Further, the safety belt fixed support also includes a set of sheath on the coat, and the sheath can be slided along overcoat It is dynamic, and the sheath limitation sheath and base when sliding into the connecting portion of overcoat and base rotation.

Further, length of the length of the interior bar more than overcoat.

Further, the location structure includes keeper, first location hole for being located at overcoat top and several edges Equally distributed second location hole of interior bar length direction, the keeper sequentially passes through the first location hole and any second location hole Slip of the interior bar along overcoat is limited afterwards.

Further, the bearing plate is grating board structure.

Further, the framework platform includes the entablature sill parallel with entablature and is located at entablature with lower horizontal stroke Rectangle load-bearing frame between beam, the bearing plate is connected on load-bearing frame, and the base is connected on entablature or sill.

Further, the hook auxiliary section is suspension ring structure.

The beneficial effects of the utility model：Disconnecting switch of the present utility model overhauls anti-fall device, puts down framework when using Platform is placed on disconnecting switch base, staff ascended a height using ladder etc. after by trample on bearing plate, with larger Moving range, easy access；Seat belt hanger is fixed by being buckled on hook auxiliary section, the effect of safety belt is sent out Wave, it is ensured that maintenance safety；Meanwhile, bumper is the telescopic structure of adjustable length, has both been easy to the staff of different heights Use, be easy to carry again and receive；The utility model security reliability is high, carry and convenient disassembly, live strong applicability, effectively Improve the security that staff is aloft overhauled to disconnecting switch.
