Description
Technical field
The present invention relates to flame-proof type multi-loop combined switch equipment technical field, particularly a kind of lever type mechanical interlocked mechanism of multi-loop combined switch.
Background technology
Underground coal mine electrical equipment is clearly emphasized regulation, and in down-hole, main chamber great Gai in service can not open electric equipment.Opening the large lid in main chamber must first cut off the electricity supply, and forbids energising when the large Gai Wei in main chamber closes simultaneously.At present, mining underground coal mine electrical equipment is for guaranteeing safe operation, and a kind of is bolted mechanism, as shown in Figure 1, existing bolted mechanism adopts fastening bolt 13, the large lid 12 in main chamber is fixed on switchgear 11 by fastening bolt 13, and alarm plate 14 is attached on the large lid 12 in main chamber, and isolating switch 15 is arranged on switchgear 11, this bolted mechanism simple in structure, but install and maintenance inconvenience, and not too safe, must there is the assurance of strict management system.Another kind is quick door opener structure, mostly adopt hoisting type and left-right movable type mechanism, electric and mechanical interlocking is mostly designed to gear and adds tooth bar, slide block adds the mode ，Ci mechanism processing such as spring, installs complicated, once spring is malfunctioning, will there is slide block malfunctioning, after slide block is malfunctioning, just there will be main chamber great Gai not open or main chamber great Gai open can Guan Bushang, the effect of final loss of interlocking.Simultaneously also can only be for the switchgear below two large lids in main chamber.If feeder number is many, need three above main chamber great Gai ，Ci mechanisms just helpless.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of lever type mechanical interlocked mechanism of multi-loop combined switch, and it has adopted lever operation principle and has been suitable for installing and using in multi-loop combined switch equipment.
For solveing the technical problem, the invention provides a kind of lever type mechanical interlocked mechanism of multi-loop combined switch, it is characterized in that, it comprises isolating switch main shaft, isolating switch, linkage block, the first lever rotating type mechanism, connecting rod, the second lever rotating type mechanism, interlocking segment, the first main chamber great Gai, the second main chamber great Gai, the 3rd main chamber great Gai, door-opening mechanism, isolating switch main shaft is fixed on isolating switch and through linkage block, linkage block is connected with rod slide, the second lever rotating type mechanism and interlocking segment are slidably connected, the first lever rotating type mechanism is connected with rod slide, the first main chamber great Gai, the second main chamber great Gai, the 3rd large lid in main chamber is sequentially arranged, the first main chamber great Gai, the 3rd large lid in main chamber and interlocking segment are fixed, door-opening mechanism and the first main chamber great Gai, the second main chamber great Gai, the 3rd large lid in main chamber connects.
Preferably, the two ends, left and right that are shaped as of described isolating switch main shaft are curve, and upper and lower two ends are straight line.
Positive progressive effect of the present invention is: multi-loop combined switch, when work operation, can not be opened main chamber great Gai; Open main chamber great Gai, must first cut off the electricity supply; Power connection, just can carry out after the large lid in main chamber that must first close, and has guaranteed safe operation and the maintenance of multi-loop combined switch.

Embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
As shown in Figure 2, lever type mechanical interlocked mechanism of multi-loop combined switch of the present invention comprises isolating switch main shaft 1, isolating switch 2, linkage block 3, the first lever rotating type mechanism 4, connecting rod 5, the second lever rotating type mechanism 6, interlocking segment 7, the first large lid 8 in main chamber, the second large lid 9 in main chamber, the 3rd large lid 10 in main chamber, door-opening mechanism 21, isolating switch main shaft 1 is fixed on isolating switch 2 and through linkage block 3, linkage block 3 is slidably connected with connecting rod 5, the second lever rotating type mechanism 6 and interlocking segment 7 are slidably connected, the first lever rotating type mechanism 4 is slidably connected with connecting rod 5, the first large lid 8 in main chamber, the second large lid 9 in main chamber, the 3rd large lid 10 orders in main chamber are arranged, the first large lid 8 in main chamber, the 3rd large lid 10 in main chamber and interlocking segment 7 are fixing, the large lid 8 of door-opening mechanism 21 and the first main chamber, the second large lid 9 in main chamber, the 3rd large lid 10 in main chamber connects.The two ends, left and right that are shaped as of isolating switch main shaft 1 are curve, and upper and lower two ends are straight line.
The first lever rotating type mechanism 4 be closing of interlocking isolating switch and minute, together with linkage block 3, connecting rod 5 all form with the first lever rotating type mechanism 4, linkage block 3 can be isolated switch 2 and connect and pin and can not move left and right.The second lever rotating type mechanism 6 is Push And Releases of the large lid in the main chamber of interlocking, and the first large lid the 8, second large lid 9 in main chamber in main chamber, the 3rd large lid 10 in main chamber are because being pinned by the second lever rotating type mechanism 6, and such the second lever rotating type mechanism 6 is also lockable.Three main chamber great Gai can not open because pinning, and this can not uncap and safe operation under energising operation working condition with regard to having guaranteed multi-loop combined switch.
When multi-loop combined switch need to be uncapped maintenance, first must be by isolating switch disjunction, isolating switch main shaft 1 is in position shown in Fig. 3, at this moment just release of isolating switch.Turn clockwise 4 to 90 °, the first lever rotating type mechanism, the linkage block 3 interconnecting and connecting rod 5 40mm that just can move right, now the second lever rotating type mechanism 6 is all unlocked.As long as 6 to 90 °, up time the second lever rotating type mechanism, more just can be moved to the left 40mm by rotating the large lid 8 in the main chamber of door-opening mechanism 21, the first, the second large lid 9 in main chamber, the 3rd large lid 10 in main chamber just can move right 40mm and open.
After three main chamber great Gai open, as shown in Figure 4, because isolating switch is lockable, just can not turn to again closing position, guarantee can not switch on after isolating switch is uncapped.Want the work of again switching on, all exactly main chambeies of unique method large lid Men Douyi shuts and puts in place, more again by being rotated counterclockwise the second lever rotating type mechanism 6 to zero-bit position, so the large cover lock in all main chambeies is lived.Untie the linkage block 3 that interconnects and the interlocking of connecting rod 5, just can be rotated counterclockwise the first lever rotating type mechanism 4 to zero-bit position, drivening rod 5, linkage block 3 is moved to the left 40mm, and now isolating switch main shaft just can rotate to the position of closing.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, do not deviating under the prerequisite of principle of the present invention and essence, can make various changes or modifications to these execution modes.Therefore, protection scope of the present invention is limited by appended claims.
