抽出式功能单元的电操联锁机构

Electro-control interlocking mechanism of draw-out type functional unit

Abstract

本实用新型涉及低压抽出式功能单元技术领域,特别是一种抽出式功能单元的电操联锁机构。它包括基板、牵引板、解锁板、辅助开关和联锁板。该机构具有与抽屉推进机构的机械联锁,它通过解锁板带动牵引板、联锁板、锁定轴,实现了只要推进机构的操作摇手柄进入机构,辅助开关即失电,无法向电操机构提供合闸电源,只有在抽屉进入位置锁定,机构操作手柄拔出状态,机构操作孔堵死状态,才能给电操机构提供合闸电源,推进机构的摇手柄进入必须解锁,只要解锁,牵引板动作,辅助开关处于失电状态,可实现电操抽屉推进操作的安全防护,确保切断负载方可移动抽屉的防护操作技术要求。
The utility model relates to the technical field of a low-voltage draw-out type functional unit, in particular to an electro-control interlocking mechanism of a draw-out type functional unit. The mechanism comprises a base plate, a drawing plate, an unblocking plate, an auxiliary switch and an interlocking plate. The mechanism is mechanically interlocked with a drawer advancing mechanism, and drives the drawing plate, the interlocking plate and a locking shaft through the unlocking plate, so that as long as an operating cranking handle of the advancing mechanism enters the mechanism, the electricity of the auxiliary switch is cut, and power source for switching on can not be supplied to the electro-control interlocking mechanism, only the drawer enters the position and is locked, an operating handle of the mechanism is in a pulled out state, and an operating hole of the mechanism is in a closed state, power source for switching on can be supplied to the electro-control interlocking mechanism, if the cranking handle of the advancing mechanism is needed to enter the mechanism, unlocking is needed be performed, so long as unlocking is performed, the drawing plate moves, and the auxiliary switch is in a power failure state, the safety protection to the advancing operation of the electro-control drawer can be realized, and the protection operation technical requirement that the drawer can move by cutting a load is ensured.
