Auxiliary device for power system overhaul
The invention relates to power overhaul auxiliary equipment, and in particular relates to an auxiliary device for power system overhaul. The technical problem that an opening device of an existing underground power distribution room overhaul channel is difficult to open is solved. A channel outer cover body can be fixed through connecting rods and extension springs which are rotatably connected with the two sides of the channel outer cover body and a cover body fixing block. When the channel outer cover body is opened from the inside, only a channel inner cover body needs to be inwards pulledopen, the channel outer cover body can be opened through cooperation of an inner cover body ejector block and an outer cover body ejector block according to the lever principle, the height of a secondrotating screw is higher than that of a first fixing screw, and therefore the channel outer cover body is pulled up through the extension springs. The device is simple in structure, the overhaul channel does not need to be opened through a thrust mechanism, and the problems that the thrust mechanism is complex in structure, high in failure rate and high in maintenance cost are solved on the basisof solving potential safety hazards.
本发明涉及电力检修辅助设备，具体为一种用于电力系统检修的辅助装置。解决了目前地下配电房检修通道的开启装置较难开启的技术问题。本发明利用通道外盖体和盖体固定块两侧转动连接的连杆和拉伸弹簧，可将通道外盖体固定。在从内部打开通道外盖体时，只需向内拉开通道内盖体，就可以通过内盖体顶块和外盖体顶块的配合，利用杠杆原理顶开通道外盖体，使第二转动螺钉的高度高于第一固定螺钉的高度，从而使拉伸弹簧将通道外盖体拉起。本装置结构简单，无需通过推力机构进行检修通道的打开，在解决了安全隐患的基础上避免了推力机构结构复杂，故障率高和维护成本高的问题。
