The invention discloses a safety-type operating mechanism used for a grounding knife gate. The safety-type operating mechanism is provided with an operation box. A bearing block A and a rolling bearing A are installed at the top part of the operation box. An output shaft is installed in the rolling bearing A. A bevel gear wheel A is installed at the bottom end of the output shaft. A bearing block C and a bearing block B are installed at the front and rear ends of the operation box respectively. Rolling bearings C and B are installed in the bearing blocks C and B respectively. An input shaft is installed between the rolling bearing C and the rolling bearing B. A bevel gear wheel B which engages with the bevel gear wheel A is also installed on the input shaft. One end of the input shaft, extending out of the rolling bearing B, is provided with a square head. The mechanism is characterized in that a connection plate is installed at the right end of the operation box; a protective cover is hinged with the connection plate; the protective cover is provided with a groove which covers the bearing block B; an angle steel is also installed at the left side of the protective cover on the operation box; and the angle steel and the protective cover are locked together through a safety lock. The safety-type operating mechanism used for the grounding knife gate is simple in structure and capable of preventing people without authorization from operating the grounding knife gate randomly so that use security is improved significantly.
Description
technical field [0001] The invention relates to an operating device for a grounding switch in a substation, in particular to a safe operating mechanism for a grounding switch. Background technique [0002] The grounding knife switch is composed of an operating mechanism, a connecting rod mechanism, and a grounding movable contact installed on the tower. When the grounding knife switch is grounded, the input shaft in the operating mechanism drives the output shaft to rotate, and the output shaft passes through the The connecting rod mechanism makes the grounding movable contact rotate 90° and overlap with the maintenance line to realize grounding. [0003] The operating mechanism on the traditional grounding knife switch has an operating box. The top of the operating box is equipped with a bearing seat A, and an output shaft is installed in the bearing seat A through a rolling bearing A. One end of the output shaft extending into the operating box is equipped with a Bevel ge...
