Description
Technical field
The utility model relates to a kind of hydraulic support reversal valve locking device.
Background technology
At present, most of underground hydraulic support frame action of domestic use is controlled by hand-operated direction valve group, and during the inoperation of reversal valve group, reversal valve group operating grip is outside exposed, without any latch-up protection measure.Because coal mine fully-mechanized mining working operating space environment is narrow, reversal valve group requires again the position being arranged on convenient operation, so in coal mining process reversal valve group operating grip because unexpected to collide with, the form such as extruding easily produces misoperation, thus damage equipment impact is produced, What is more there is personal safety accident.
Utility model content
The purpose of this utility model be to provide a kind of prevent the misoperation of hand-operated direction valve group appearance, the hydraulic support reversal valve locking device that reduces contingency occurrence probability.
For achieving the above object, the utility model adopts following technical scheme: hydraulic support reversal valve locking device, comprise two valve plates being installed in hand-operated direction valve group two ends respectively, two close lock bar is connected with between two valve plates, described deadlock lever comprises straight bar part and is separately positioned on the two upwards bending parts at straight bar part two ends, the straight bar part of deadlock lever is positioned at the below of two valve plates, every root deadlock lever two upwards hinged with two valve plate the bottoms respectively and straight bar part of deadlock lever of bending part can upwards overturn, two straight bar parts of two close lock bar are that parallel interval is arranged, gap is provided with between two straight bar parts of two close lock bar, the all operations bar of hand-operated direction valve group all stretches out downwards from the gap between two straight bar parts, buckle is provided with between two straight bar parts of two close lock bar, described buckle is provided with jack and draw-in groove, buckle also can be rotated around this deadlock lever straight bar part by the straight bar part grafting of its jack and one of them deadlock lever, and the draw-in groove of buckle is that notch down be located on the straight bar part of another deadlock lever.
Described buckle arranges two.
Hydraulic support reversal valve locking device described in the utility model, has that structure is simple, the advantage of flexible operation, the hand-operated direction valve group not used time, buckle connects two close lock bar, realize the locking of reversal valve group, prevent the appearance of reversal valve group misoperation, reduce contingency occurrence probability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of buckle and two close lock bar.
Detailed description of the invention
By the hydraulic support reversal valve locking device shown in Fig. 1-Fig. 2, comprise two valve plates 2 being installed in hand-operated direction valve group 1 two ends respectively, the reversal valve group that described hand-operated direction valve group 1 is underground hydraulic support frame, hand-operated direction valve group 1 comprises one group of hand-operated direction valve, hand-operated direction valve comprises valve body and action bars 8, in hand-operated direction valve group 1, the valve body of hand-operated direction valve is fixedly connected sequentially, and in hand-operated direction valve group 1, all operations bar 8 of hand-operated direction valve is to downward-extension under idle closed condition.Hand-operated direction valve group 1 is existing common equipment on underground hydraulic support frame, therefore does not describe in detail.
Two valve plates 2 are installed in the both ends of the surface of hand-operated direction valve group 1 respectively, and valve plate 2 is connected by bolt 5 with the end face of hand-operated direction valve group 1, and valve plate 2 is vertical extension, and valve plate 2 bottom extends to the downside of hand-operated direction valve group 1 valve body part.
Two close lock bar is connected with between two valve plates 2, described deadlock lever comprises straight bar part 7 and is separately positioned on the two upwards bending parts 3 at straight bar part 7 two ends, whole deadlock lever is in " U " font, every root deadlock lever two upwards bending part 3 is hinged with two valve plate 2 bottoms respectively, the upwards bending part 3 of every root deadlock lever is all hinged by pin 6 and corresponding valve plate 2 bottom, on same deadlock lever, two two pins 6 that upwards bending part 3 connects are conllinear setting, and the straight bar part 7 of deadlock lever upwards can overturn around this deadlock lever pin 6 that upwards bending part 3 connects, when the straight bar part 7 of deadlock lever upwards overturns, action bars 8 rotatable of hand-operated direction valve group 1.
The straight bar part 7 of deadlock lever is positioned at the below of two valve plates 2, and the straight bar part 7 of deadlock lever is positioned at the below of hand-operated direction valve group 1 valve body part, two straight bar parts 7 of two close lock bar are parallel interval setting, be provided with gap between two straight bar parts 7 of two close lock bar, all operations bar 8 of hand-operated direction valve group 1 all stretches out downwards from the gap between two straight bar parts 7.
Be provided with buckle 4 between two straight bar parts 7 of two close lock bar, buckle 4 is plate body, and buckle 4 is provided with jack 9 and draw-in groove 10, and draw-in groove 10 is arranged on the bottom side of plate body, and draw-in groove 10 is longitudinally penetrating along deadlock lever straight bar part 7.Buckle 4 also can be rotated around this deadlock lever straight bar part 7 by straight bar part 7 grafting of its jack 9 with one of them deadlock lever, the diameter of buckle 4 jack 9 is greater than the diameter with its grafting deadlock lever, and the straight bar part 7 of this deadlock lever can realize buckle 4 after being inserted through from the jack 9 of buckle 4 and rotates around this deadlock lever like this; The draw-in groove 10 of buckle 4 is that notch down be located on the straight bar part 7 of another deadlock lever, and namely another root deadlock lever straight line portion passes from the draw-in groove 10 of buckle 4.
Described buckle 4 arranges two, two buckles 4 all with same deadlock lever grafting.Certainly, the utility model is not limited to above-mentioned form, and the quantity of buckle 4 can arrange multiple; In addition, each buckle 4 is plugged on arbitrary deadlock lever, all can reach goal of the invention.
Hydraulic support reversal valve locking device described in the utility model, when hand-operated direction valve group 1 uses, manually buckle 4 is opened, rotating buckle 4 makes the draw-in groove 10 of buckle 4 depart from from corresponding deadlock lever, the straight bar part 7 of the deadlock lever departed from from draw-in groove 10 around this deadlock lever upwards bending part 3 connects pin 6 and upwards rotates, realize reversal valve group and operate freely; During the inoperation of reversal valve group, locked by two groups of deadlock levers by buckle 4, two close lock bar is all immovable, the action bars 8 not rotatable of manual operation method, realizes the locking of reversal valve group operating grip thus.
