Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed description:
As shown in Figures 1 to 4, the Ore Explosion Suppression Switch Two-Door Blocking Device that provides for the utility model, two-door locking device comprises the first activity orientation part and the second activity orientation part that is installed on the explosion-proof switch body 1, be located at an explosion-proof switch left side respectively, driving first guide vane end stop 21 that the first activity orientation part moves and driving second guide vane end stop 31 that the second activity orientation part moves on the door body of right chamber, and the locating piece 32 that fastens with the first activity orientation part after moving, the second activity orientation part after described the moving matches with described first guide vane end stop 21 and locatees first guide vane end stop 21.
As shown in Figure 1, in the present embodiment, locking device of the present utility model is installed on the explosion-proof switch, and explosion-proof switch comprises explosion-proof switch body 1, with the left and right chamber door of explosion-proof switch body 1 flexible connection.Close the locked instrument of left and right chamber door, and insulating phase-change switch handle 5.The chamber door is the parallel-moving type double door.Left and right chamber door can rotate with respect to explosion-proof switch body 1, but the while move left and right.Because explosion-proof switch belongs to existing mature technology, concrete internal structure is not shown here in the drawings, only explanation can realize the structure of parallel-moving type double door, that is: left and right chamber door and explosion-proof switch body 1 are hinged by two jointed shafts respectively, have the chute of ccontaining driving eccentric shaft on jointed shaft.This structure just can make left and right chamber door not only can rotate with respect to the explosion-proof switch body, and can move left and right.
As shown in Figure 4, the locked instrument on the explosion-proof switch comprises the fastener of being located at respectively on left chamber door 2 and the right chamber door 34, and opens the draw-in groove 4 ' that fastens at the fastener 4 with on left chamber door 2 and the right chamber door 3 on the explosion-proof switch body 1.
In addition, be provided with the controller that is used to control and/or regulate external electrical equipment in the explosion-proof switch body 1, in the present embodiment, controller is programmable PLC controller.
As Fig. 2, locking device shown in Figure 3, wherein, the first activity orientation part comprises slide block 61, and the pull bar 62 that is connected with slide block 61 is with spring 63 on the pull bar 62, and pull bar 62 is placed in the housing 64, and pull bar 62 front ends stretch out in housing 64.Housing 64 is fixed on the explosion-proof switch body 1, and an end of spring 63 relies on the inwall of housing 64, and the other end relies on 61 slide blocks.On slide block 61, have the groove a of ccontaining locating piece 32, the slide block 61 after moving, its groove a is just in time corresponding with the position of locating piece 32, and locating piece 32 stretches in the groove a under the drive of right chamber door 3 and fastens.
First guide vane end stop 21 has a wedge shape projection 211, has the wedge shape projection 211 of a lozenges that matches with wedge shape projection 211 611, the first guide vane end stops 21 on the slide block 61 and matches with lozenges 611 on the slide block 61.When after left chamber door 2 is closed, being moved to the left, driving lozenges 611 by the projection of the wedge shape on it 211 when first guide vane end stop 21 is moved to the left and slide, move up thereby drive slide block 61.
The second activity orientation part comprises positioning sliding block 71, the push rod 72 that is connected with positioning sliding block 71, be with spring 73 on the described push rod 72, push rod 72 melts and places in the shell 74, push rod 72 front ends stretch out in shell 74, shell 74 is fixed on the explosion-proof switch body 1, and an end of spring 73 relies on the inwall of shell 74, and the other end relies on the positioning sliding block 71.Have a breach 212 on first guide vane end stop 21.Second guide vane end stop 31 has a wedge shape projection 311, has the lozenges 711 that matches with described wedge shape projection 311 on the described positioning sliding block 71, and the wedge shape projection 311 of described second guide vane end stop matches with the lozenges 711 on the described positioning sliding block.Close when right chamber door 3 and to move right, when driving second guide vane end stop 31 and moving right, wedge shape projection 311 drives lozenges 711 and slides, and moves up thereby drive positioning sliding block 71, makes the front end of push rod 72 snap in breach 212.So just, also just located left chamber door 2, left chamber door 2 can't have been moved under the situation that right chamber door is not opened open first guide vane end stop, 21 location.
As shown in Figure 1, on explosion-proof switch body 1 and chamber door, also be provided with the electrical interlock stop button 8 that makes the vacuum contactor outage, make the interior six side's latch shaft and the lining 9 of described insulating phase-change switch handle 5 lockings, with interior six side's latch shaft and lining 9 corresponding locking bearings 10.Because this part-structure belongs to existing mature technology, can implement for a person skilled in the art, propose here just in order to describe the integrality of the explosion-proof switch that the utility model locking device is installed.So no longer its internal structure and connected mode are given unnecessary details here.
The explosion-proof switch of the utility model locking device is installed, it opens and closes a left side, the process of right chamber door as shown in Figures 1 to 4, explosion-proof switch is being opened a left side, during right chamber door, at first press electrical interlock stop button 8, make the vacuum contactor outage, under the state of no-load, the control crank 5 of insulating phase-change switch is placed center-off position again, thereby, rotate lining and latch shaft 9 with interior six side's spanners, make it can not rotate combined floodgate 5 lockings of insulating phase-change switch handle by connecting rod and interlinked mechanism, with the flat side of lining, be horizontal level simultaneously, aim at the breach of right chamber door 3 locking bearings 10, so right chamber door 3 just can be opened to left.With the locking of 5 on the locking of 1 of the locking of upper right chamber door and insulating phase-change switch handle 5 and explosion-proof switch body, latch shaft and insulating phase-change switch handle, kept existing design basically.
Description by said structure, the locking process of explosion-proof switch is: when left chamber door 2 is closed to left, be fixed on first guide vane end stop 21 on the left chamber door 2 with left chamber door to left, wedge shape projection 211 provided thereon is with the slide block on the first activity orientation part 61 jack-up upwards, after the left-hand door translation puts in place fully, fastener 4 snaps in the draw-in groove 4 ', can close right chamber door.At this moment, the locating piece 32 that is fixed on the door of right chamber can embed in the groove a of slide block 61, then right chamber door is to right translation, second guide vane end stop 31 is the wedge shape projection 211 of below, with positioning sliding block 71 jack-up upwards, and then the push rod that will be connected 72 jack-up upwards with positioning sliding block 71, thereby extend in the breach 212 of first guide vane end stop 21, the door locking of left chamber is fixed and can not translation can not be opened, at this moment operation sequence must be to close earlier just can close right chamber door after left chamber door puts in place, otherwise slide block 21 is with the groove a of the locating piece 32 embedding slide blocks 21 of the right chamber of overslaugh door, and right chamber door does not just close.
Releasing process is: interior six side's latch shaft on explosion-proof switch body 1 and lining 9 flat horizontals are in horizontal level, and when just insulating phase-change switch handle 5 was open position, the locking bearing 10 on the door of right chamber was unlocked, and can open.After the translation left of right chamber door was opened, push rod 72 was at the breach 212 that breaks away under the effect of spring 73 on first guide vane end stop 21, and left chamber door 2 also just can have been opened in release.
