Description
Technical field
The utility model relates to a kind of coal mine shaft lining S. A. tank curtain door, especially a kind of coal mine shaft lining S. A. tank curtain door closing appliance.
Background technology
At present, the pass automatic cage curtain using in coal mine shaft lining, is to transfer by the gravity of tank curtain door, and tank curtain door both sides drive it to move up and down along guide rail by steel rope, when point hook work is opened tank curtain door, and effort, the labour intensity of some hook work is large.Meanwhile, in the time relieving lifting personnel, when point hook workman work is opened tank curtain door, often there is the phenomenon of safety cap, be unfavorable for a safety of hook work.Secondly, in cage operational process, as fault, braking suddenly, tank curtain door is easily upspring, and the safety that is unfavorable for taking advantage of tank personnel He transports material is unfavorable to the safety of pit gear, the existing weak point of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model, is exactly for the existing deficiency of prior art, and provides a kind of locking property coal mine shaft lining S. A. tank curtain door closing appliance good and that easily open.
This programme is achieved by the following technical measures: this coal mine shaft lining S. A. tank curtain door comprises the flute profile erecting frame being fixedly connected with tank curtain door lower end with closing appliance, in described erecting frame, middle part is provided with two latchs, two latchs are the sketch plate of form fit, the abutting end of two latchs is hinged, the other end is hinged with respectively locking lever, the other end of two locking levers stretches out respectively erecting frame, in described erecting frame, be provided with the supporting seat coordinating with the two ends of locking lever, on one of them supporting seat, be fixedly connected with horizontal reset spring, the other end of spring is fixedly connected with drive block, drive block is fixedly connected with locking lever.
On the end face at the two ends of above-mentioned erecting frame, be provided with through hole, the diameter of through hole is greater than the diameter of locking lever, can guarantee that like this horizontal reciprocating that erecting frame can not affect locking lever moves.
Above-mentioned two latchs are in the time of horizontality, through hole 2-3cm is stretched out in the end of locking lever, so both can guarantee the normal locking of tank curtain door, and after release, erecting frame still can be stretched out in the end of locking lever, prevents that locking lever is fully retracted the end of erecting frame after erecting frame and can stops stretching out of locking lever.
Above-mentioned two sketch plates are along both hinge-point Central Symmetries, are opening tank curtain behind the door, and two sketch plates can be superimposed, can be that two locking levers are abdicated enough spaces locking lever is retracted like this, realize the smooth disengagement of locking lever and vertical framework.
The cross-sectional plane of above-mentioned flute profile erecting frame is the U-lag of opening upwards, both can realize the normal mounting of latch and locking lever, also the operation of convenient some hook work.
Above-mentioned spring fitting is on the close supporting seat of through hole.
The beneficial effect of this programme can be learnt according to the narration to such scheme, this coal mine shaft lining S. A. tank curtain door is with in closing appliance, point hook work upwards lifts two latchs, and two latchs drive two locking lever parallel motions, and two locking levers are retracted in erecting frame, make the release smoothly of tank curtain door, after release, unclamp two latchs, under the effect of horizontal reset spring, two locking lever returns, and drive the synchronous return of two latchs.The locking property of this closing appliance is good, and locking and open operation easy, can alleviate a labour intensity of hook work by actv., can avoid a hook work to fall the phenomenon of safety cap when firmly opening tank curtain door simultaneously, guaranteed the safety of some hook work.As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
