The invention relates to a double-quick-opening-door multi-isolating switch cabinet locking mechanism which belongs to the technical field of explosion-proof switch cabinet locking systems. The invention provides a mechanism for locking an explosion-proof switch cabinet with double quick-opening doors and a plurality of isolating switches. The adopted technical scheme of the double-shutter multi-isolating switch cabinet locking mechanism is as follows: planes are both milled on the side surfaces of a first locking shaft and a second locking shaft; a first gear, a second gear and a transmission gear are all installed on a gear fixing plates by shafts; the first gear is meshed with the transmission gear, and the second gear is also meshed with the transmission gear; a first rack locking rod and a second rack locking rod are arranged on the inner wall of an explosion-proof shell by support columns; the first locking shaft is fixedly connected with the center of the first gear after penetrating through the explosion-proof shell; the first gear is meshed with the first rack locking rod; the second locking shaft is fixedly connected with the center of the second gear after penetrating through the explosion-proof shell; and the second gear is meshed with the second rack locking rod. The double-quick-opening-door multi-isolating switch cabinet locking mechanism disclosed by the invention is used for locking the double-quick-opening-door multi-isolating explosion-proof switch cabinet.
Description
technical field [0001] The invention relates to a locking mechanism for a double-fast opening multi-isolation switch cabinet, which belongs to the technical field of locking systems for flameproof switch cabinets. Background technique [0002] Various standards of explosion-proof switchgear for explosive gas atmospheres require that: when the explosion-proof switchgear is equipped with an isolating switch, each interlock between the isolating switch and the cover or door of the explosion-proof switchgear shall ensure that only when Covers and doors are only possible to open when the contacts of the isolating switch are completely cut off. This is an important means for the flameproof performance of the flameproof switchgear, the safety of on-site production and the personal safety of the operators. Now, some large explosion-proof switch cabinets usually have two quick-opening doors and 2, 4 or even more isolating switches, and may be installed in separate chambers. The loc...
