Abstract
The utility model relates to a mechanical locking mechanism of an easy-opened main explosion-proof chamber, which comprises a locking block, a locking rod, a guide block, a steel sleeve, a button rod, a spring, a copper sleeve, a locking travel limit switch and a power switch with a handle. The locking block is installed on a door of the main explosion-proof chamber, and the guide block, the locking rod, the steel sleeve and the power switch with a handle, corresponding to the locking block, are installed on a side plate of the main explosion-proof chamber. A cone body which is big at one end and small at the other end is installed in the middle part of the locking rod, the two ends of the locking rod respectively corresponds to the locking block and a locking hole on the power switch, and the button rod is installed in the steel sleeve and one lateral end of the button rod is contacted with the cone body. With the adoption of the mechanical locking mechanism, big loss due to the electrified door opening of the operators can be efficiently avoided. The mechanical locking mechanism has a simple, new and reliable structure, saves the space in the chamber, reduces the cost of materials, meets the performance requirements, and can be applied to the similar products.
Description
Technical field
The utility model relates to a kind of mechanical lock, the mechanical lock of the fast opening type master flame proof cavity that uses on a kind of specifically mine anti-explosion electric equipment.
Background technology
At present, the interlock form of China's coal-mine down-hole employed fast opening type master flame proof cavity explosion-proof electric apparatus mainly contains two kinds: a kind of is that main flame proof cavity is provided with interlocking device, promptly have only under the situation with circuit breaker or reversing switch disconnection, door closure could be opened, but the mains side of circuit breaker or reversing switch is still charged, just adorn the alarm plate of " having ", do not had thoroughly to solve the problem of the electrified body that do not have in the main chamber.Another kind is to have increased a travel switch under above-mentioned situation, the mains side outage of promptly in opening the process of door closure, circuit breaker or commutation being opened, but this kind mode must be controlled the position of door closure and travel switch well, otherwise the electric spark that travel switch produces when opening door closure can reach concentration the gas of certain limit to ignite, and the set travel switch of this kind situation this moment has but become ignition source.
The utility model content
Desire to open the door the problem of electrified body of not having in the master chamber when covering in order thoroughly to solve, the utility model provides a kind of mechanical lock of fast opening type master flame proof cavity, when operating personnel desire to open door closure, electric body can be stopped to have in the main cavity, the loss of personal injury and property can be effectively avoided causing.
The technical scheme that its technical problem that solves the utility model adopts is: this blocking mechanism comprises Breech block, deadlock lever, guide pad, steel bushing, button spindle, spring, copper sheathing, locking travel switch and mains switch with handles; On the door closure of this main blast chamber, be provided with a Breech block, the guide pad corresponding with Breech block, deadlock lever, steel bushing are housed on the side plate of main explosion-proof chamber and the mains switch of obturator hernia handle is arranged, the deadlock lever middle part is provided with one the one little tapering body of the big end of end, the two ends of deadlock lever match corresponding with the obturator hernia of Breech block and mains switch respectively, be provided with the button spindle that a horizontal end contacts with cone in the steel bushing, the other end of button spindle and locking travel switch Contact Transmission; When operating personnel desire to open door closure, at first the handle with mains switch forwards " outage " position to, main flame proof cavity control circuit outage this moment, but mains side is still charged, rotating deadlock lever then falls back in the obturator hernia of mains switch handle away from the Breech block on the door closure, this moment is because the cone on the deadlock lever cuts off the power supply the mains side in the main explosion-proof chamber by button spindle motion compresses locking travel switch, thus the state that has cut off the power supply fully in the cavity before having realized uncapping.
The beneficial effects of the utility model are: this mechanical lock, can allow operating personnel desire to open when main explosion-proof chamber overhauls cuts off the power supply mining appliance switch fully, can effectively avoid charged the uncapping of operating personnel that the massive losses that dangerous accident caused takes place, and it is simple in structure, novel, reliable, cabinet space and material cost had both been saved, can satisfy performance requirement again, and can on product of the same type, promote the use of.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is a structural principle schematic diagram of the present utility model.
1. Breech blocks among the figure, 2. deadlock lever, 3. guide pad, 4. steel bushing, 5. button spindle, 6. spring, 7. copper sheathing, 8. locking travel switch, 9. mains switch.
Embodiment
In the drawings, this blocking mechanism comprises Breech block 1, deadlock lever 2, guide pad 3, steel bushing 4, button spindle 5, spring 6, copper sheathing 7, locking travel switch 8 and mains switch 9 with handles; On the door closure of this main blast chamber, be provided with a Breech block 1, the guide pad corresponding with Breech block 3, deadlock lever 2, steel bushing 4 are housed on the side plate of main explosion-proof chamber and the mains switch 9 of obturator hernia handle is arranged, deadlock lever 2 middle parts are provided with one the one little tapering body of the big end of end, the two ends of deadlock lever 2 match corresponding with the obturator hernia of Breech block 1 and mains switch respectively, be provided with the button spindle 5 that a horizontal end contacts with cone in the steel bushing 4, the other end of button spindle 5 and locking travel switch 8 Contact Transmission; When operating personnel desire to open door closure, at first the handle with mains switch 9 forwards " outage " position to, main flame proof cavity control circuit outage this moment, but mains side is still charged, rotating deadlock lever 2 then falls back in the obturator hernia of mains switch 9 handles away from the Breech block on the door closure 1, this moment is because the cone on the deadlock lever 2 cuts off the power supply the mains side in the main explosion-proof chamber by button spindle 5 motion compresses locking travel switches 8, thus the state that has cut off the power supply fully in the cavity before having realized uncapping.
