Description

Temporary safety belt hanging point device for maintenance inspection of indoor switch cabinet Technical Field The utility model relates to the technical field of safety belt hanging point fixing devices, in particular to a temporary safety belt hanging point device for maintenance and inspection of an indoor switch cabinet. Background In the daily maintenance of power equipment, the maintenance operation of indoor cubical switchboard often needs the operating personnel to climb to cabinet body top and carries out the high altitude construction. The safety belt is required to be hung and prevented from falling during operation, and the safety belt hanging point position is unavailable due to the fact that the upper part of the switch cabinet is quite open due to the fact that the appearance of the indoor switch cabinet is regular, and potential safety hazards exist in maintenance work. In order to ensure safety, the hanging of the anti-falling safety belt is indispensable, and at present, a conventional solution is to build a fixed insulating scaffold, and provide hanging points for the safety belt by erecting a temporary supporting structure. However, such scaffolds are assembled from a large number of parts, the construction process is cumbersome and time-consuming, and because of their fixed dimensions, it is difficult to adapt to the layout requirements of the switch cabinets of different specifications. More prominently, the scaffold assembly itself often needs the operation of climbing high by operators, which not only has low efficiency, but also increases the risk of falling from high altitude. Furthermore, the scaffolding that has been built is often heavy and difficult to move, especially in small spaces or complex environments. On the other hand, because the switch cabinet top area is open and lacks fixed anchor point, the supporting structure coverage of temporarily putting up is limited, and buffering shock-absorbing function is not enough, in case the accident falls, is difficult to effectively absorb the impact force, further threatens the operating personnel safety. In view of the foregoing, a need exists for a dedicated belt hitch that addresses the above-described issues.
