Abstract
The utility model relates to a mine flameproof switch switch-on positioning device. A fixed contact mounting plate (7) is fixed inside a flameproof shell. A moving contact mounting plate (1) is provided with a moving contact (2) and a control loop plug (4). The fixed contact mounting plate (7) is provided with a fixed contact (5) and a control loop socket (8). The moving contact (2) is corresponding to the fixed contact (5). The control loop plug (4) is corresponding to the control loop socket (8). The mine flameproof switch switch-on positioning device is characterized in that the moving contact mounting plate (1) is provided with a guide sleeve (3); the fixed contact mounting plate (7) is provided with a guide column (6); and the guide sleeve (3) is matched with the guide column (6). According to the mine flameproof switch switch-on positioning device, guide positioning characteristics of the guide column and the guide sleeve are utilized, and a moving contact plate and a fixed contact plate are connected and combined with each other so as to be used, and therefore, effective components can be decreased. The mine flameproof switch switch-on positioning device has the advantages of simple process, no need for welding, easiness in machining precision control, accurate engagement of the moving contact and the fixed contact, reduced emitted heat and capability of prolonging the service life of a switch.
Description
Technical field
The utility model relates to flame-proof type switch under a kind of coal mine, is specifically related to a kind of mining explosion-proof switch combined floodgate positioner.
Background technology
Traditional flame-proof type Switch main body under coal mine (aggregate of electric elements in explosion-resistant enclosure) combined floodgate positioning and guiding adopts pulley slippage plug mode, because there is more transition annexation-be contained in contact plate by moving contact between the dynamic and static contact of closure, contact plate is contained on fixed mount, and fixed mount is loaded on pulley; And slippage guide rail is fixed on another fixed mount, fixed mount is fixed on flameproof enclosure again, shell is fixed upper static contact mounting panel again, and fixed contact is fixed on fixed contact mounting panel, like this because middle transition link is too much, cumulative errors are larger, cause switch dynamic/static contact to aim at closed difficulty, complex manufacturing technology, and because of the local contact of switch contact, be easy to heating, affect switch useful life.
Summary of the invention
The purpose of this utility model is the defect in order to overcome prior art, provide one efficiently, dynamic and static contact location closing device accurately.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of mining explosion-proof switch combined floodgate positioner, fixed contact mounting panel (7) is fixed in flameproof enclosure, moving contact mounting panel (1) is provided with moving contact (2) and control loop plug (4), fixed contact mounting panel (7) is provided with fixed contact (5) and control loop socket (8), moving contact (2) is corresponding with fixed contact (5), control loop plug (4) is corresponding with control loop socket (8), it is characterized in that: moving contact mounting panel (1) is provided with guide pin bushing (3), fixed contact mounting panel (7) is provided with guide pillar (6), and guide pin bushing (3) matches with guide pillar (6).
The beneficial effects of the utility model are: utilize the guide-localization characteristic of guide pillar, guide pin bushing, it is connected and is used in combination with dynamic and static contact plate, active component is less, technique is simple, and without welding, machining accuracy is easily controlled, dynamic and static contact coincide accurately, has reduced heating, and switch life is increased.
