Abstract
The utility model relates to a bolt-on blocking mechanism of a main flameproof cavity body for an anti-explosion electric appliance. The blocking mechanism comprises a hinge, a sheltering frame, a bolt, a button rod, a spring, a copper sleeve, a steel sleeve, a blocking limit switch, a door cover and a main flameproof cavity; the steel sleeve and the hinge are arranged on the door cover of the main flameproof cavity; the button rod, the spring and the copper cover are embedded in the steel sleeve; the sheltering frame is connected with the door cover through the hinge; the blocking limit switch is arranged in the main flameproof cavity, the blocking limit switch contacts with one end of the button rod and the other end of the button rod contacts with the sheltering frame. Through the mechanical blocking mechanism, when an operation personnel is going to open and overhaul the main flameproof cavity, a mine electric appliance is totally power off, therefore the big loss which is caused by an unsafe accident when the operation personnel opens the door cover in an live environment is effectively avoided; the structure is simple, novel and reliable; the space of a box body and the material cost are reduced; the performance requirement can be met; and the blocking mechanism can be popularized and used on the products of the same type.
Description
Technical field
The utility model relates to a kind of mechanical lock of explosion-proof electric apparatus, the blocking mechanism of the bolt matable master flame proof cavity that uses on a kind of specifically mine anti-explosion electric equipment.
Background technology
At present, China's coal-mine down-hole employed bolt matable master flame proof cavity explosion-proof electric apparatus is mainly warned the operator by alarm plate and is forbidden charged uncapping.That have or increase an interlocking device again, make the operator have only under the situation that circuit breaker or reversing switch are disconnected, door closure could be opened, but the mains side of uncap back circuit breaker or reversing switch is still charged, does not have thoroughly to solve the problem of the electrified body that do not have in the main chamber.If the careless slightly person that will cause of operator gets an electric shock, and when gas density reached explosive range, the electric spark of generation can cause gas explosion accident.
The utility model content
The problem of electrified body does not have in the master chamber when opening door closure in order thoroughly to solve, the utility model provides a kind of blocking mechanism of bolt matable master flame proof cavity, when operating personnel desire to open door closure, can thoroughly cut off the power supply, can stop has electrified body in the main cavity, can effectively avoid causing the loss of personal injury and property.
The technical scheme that its technical problem that solves the utility model adopts is: this blocking mechanism comprises folding, blocks frame, bolt, button spindle, spring, copper sheathing, steel bushing, locking travel switch, door closure and main explosion-proof chamber; Steel bushing and folding are housed on the door closure of this main explosion-proof chamber; Wherein be embedded with button spindle, spring and copper sheathing in the steel bushing; Blocking frame is connected with door closure by folding; The locking travel switch is housed in the main explosion-proof chamber, an end in contact of locking travel switch and button spindle, the other end of button spindle with block bridge joint and touch.When operating personnel desire to open door closure, at first press stop button, main explosion-proof chamber inner control circuit outage this moment, but mains side is still charged, twists bolt then and will block frame and open, and button spindle ejects under the effect of spring, discharge the locking travel switch, make the interior mains side outage of main explosion-proof chamber, the bolt around the door closure can be twisted at last, thereby realize opening the state that cuts off the power supply fully in the preceding cavity of door closure.
In the drawings, the nut height of bolt equates with the interior spatial altitude that blocks frame around the main explosion-proof chamber, door closure, when bolt when screw-in is tightened fully, blocking frame is blocked, button spindle can't be depressed, the locking travel switch is in uncompressed state, the energising thereby switch can't close a floodgate.
The beneficial effects of the utility model are: this mechanical lock, can allow operating personnel desire to open mining electric equipment products switch is cut off the power supply 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.
Frame is 2. blocked in 1. foldings among the figure, 3. bolt, 4. button spindle, 5. spring, 6. copper sheathing, 7. steel bushing, 8. locking travel switch, 9. door closure, 10. main explosion-proof chamber.
Embodiment
In the drawings, this blocking mechanism comprise folding 1, block frame 2, bolt 3, button spindle 4, spring 5, copper sheathing 6, steel bushing 7, locking travel switch 8, door closure 9 and main explosion-proof chamber 10; Steel bushing 7 and folding 1 are housed on the door closure 9 of this main explosion-proof chamber; Wherein be embedded with button spindle 4, spring 5 and copper sheathing 6 in the steel bushing 7; Blocking frame 2 is connected with door closure 9 by folding 1; In the main explosion-proof chamber 10 locking travel switch 8 is housed, an end in contact of locking travel switch 8 and button spindle 4, the other end of button spindle 4 with block frame 2 and contact.When operating personnel desire to open door closure 9, at first press stop button, main explosion-proof chamber 10 inner control circuits outage this moment, but mains side is still charged, twists bolt 3 then and will block frame 2 and open, and button spindle 4 ejects under the effect of spring 5, discharge locking travel switch 8, main explosion-proof chamber 10 interior mains sides are cut off the power supply, the bolt 3 around the door closure 9 can be twisted at last, thereby realize opening the state that cuts off the power supply fully in the door closure 9 preceding cavitys.
In the drawings, the nut height of bolt 3 equates with the interior spatial altitude that blocks frame 2 around the main explosion-proof chamber 10, door closure 9, when bolt 3 when screw-in is tightened fully, blocking frame 2 is blocked, button spindle 4 can't be depressed, locking travel switch 8 is in uncompressed state, the energising thereby switch can't close a floodgate.
