The automatic normally-closed flexible car stopping device comprises a flexible car stopping net, a stay cord and a fixed plate, wherein the fixed plate is fixed on a top plate of the inclined drift; the flexible car stopping net is a steel wire net formed by connecting and fixing the middle parts of a plurality of parallel steel wire ropes through chains or ropes; the tail end of the steel wire rope is fixed on a rope clamp of the fixed plate; a net bag of the flexible car stopping net is fixedly connected with the top plate of the inclined drift through a suspension rope; two pulleys are fixed on the top plate of the inclined drift; and one end of the stay cord rounded on the two pulleys is connected with the flexible car stopping net, and the end of the stay cord is provided with a balancing weight. After the flexible car stopping net is arranged, a mine car slipping to the car stopping device is flexibly blocked by the car stopping device, so that unforeseen circumstances such as unreliable car stopping caused by a rigid car stopping device, road falling and deformation of the mine car and the like are avoided, hidden danger in collision damage to roadways, equipment facilities, pipelines and the like are avoided, and high safety and reliability are achieved; a semicircular buffer can prevent the steel wire rope from being separated from the rope clamp, so that a good buffer protection effect is achieved; and the car stopping device has a simple and flexible structure and a low cost, and is easy and convenient to operate.
Description
Technical field
The utility model relates to the flexible alley stopping device of the automatic normally closed in a kind of inclined gallery, belongs to the safety of coal mines apparatus field.
Background technology
Colliery scene has mine car usually and travels back and forth; therefore in order to guarantee the life security of field man; usually arrester can be set in the gradient tunnel lower end; arrester uses mining i beam; arrester is tilted to be installed in the middle of the inclined-drift rail; in order to stop disconnected rope, break off relations or not the mine car of the company of extension continue downward sport car, and open or close by M/C.But existing arrester and mine car area of contact are little, belong to the rigidity alley stopping device again, nonelastic and the buffering function, in case the generation sport car is too fast because of mine car speed, often causes unreliable, the unforeseen circumstancess such as mine car easily slides down, mine car distortion of keeping off a car easily, so hidden danger that exists quilts such as tunnel, installations and facilities, pipeline to break, safety problem can not guarantee, and the later stage repair time is very long, incurs loss through delay normal operation.
Summary of the invention
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of simple in structure, easy to operate and flexible alley stopping device of the automatic normally closed in inclined gallery that safe reliability is strong is provided.
The technical scheme that its technical matters that solves the utility model adopts is: the flexible alley stopping device of the automatic normally closed in a kind of inclined gallery, it is characterized in that: comprise the flexibility net of keeping off a car, stay cord and the adapter plate that is fixed on the top board of inclined gallery, the flexibility net of keeping off a car is to be connected and fixed the wire net that forms by the many steel ropes middle part that is parallel to each other by chain or rope, the steel rope end is fixed on the wire clips of adapter plate, flexibility keep off a car the net the string bag captive joint with the inclined gallery top board by suspension strop, also be fixed with two pulleys on the top board of inclined gallery, stay cord is walked around two pulleys, one end and is connected the flexibility net of keeping off a car, and the other end is provided with a clump weight.
Described steel rope two ends are equipped with semicircle energy disperser.When flexible alley stopping device is installed, the semicircle energy disperser at steel rope two ends is passed from the wire clips of adapter plate, when mine car collision flexibility is kept off a car net, the inertia of mine car may drive steel rope certain displacement takes place in wire clips, at this moment, if there are not the actv. safeguard procedures, steel rope may be deviate from from wire clips, has serious potential safety hazard.By at the steel rope two ends semicircle energy disperser being set, when steel rope was about to, semicircle energy disperser was stuck in the wire clips, thereby played good buffer protection effect, and safe reliability is strong.
For fear of many steel rope entanglements, available wire clips holds together to be incorporated into together with many steel ropes.In addition, above-mentioned suspension strop and the stay cord steel rope that is good toughness.
In addition, this alley stopping device is simple in structure flexibly, can select wirerope diameter and number of combinations to make the flexibility net of keeping off a car as required arbitrarily, and cost is low, uses leftover pieces to make.
Principle of work and process:
Under the normal condition, under the equilibrium activity of clump weight, the flexibility net of keeping off a car is positioned at the top of inclined gallery rail, alley stopping device is in closed condition, when mine car owing to disconnected rope, break off relations or when hanging the downward sport car of reason such as company and walking to the alley stopping device position, can be blocked by the flexibility net of keeping off a car, thereby play the effect that stops mine car to pass through, guarantee the life security of field man.When mine car will pass through, only need the clump weight of artificial pulling stay cord end, the flexibility net of keeping off a car is pulled to and does not hinder the height that mine car passes through, the flexible alley stopping device of the automatic normally closed in inclined gallery can be opened like this, mine car is passed through, after mine car passed through, the flexibility net of keeping off a car can revert to initial equilibrium conditions, the alley stopping device SELF CL under the effect of clump weight.
The beneficial effect that the utility model had is: provide the automatic normally closed in a kind of inclined gallery flexible alley stopping device, by the flexibility net of keeping off a car is set, when the mine car sport car can be stopped by flexibility during to alley stopping device, keeping off a car of having avoided that the rigidity alley stopping device causes is unreliable, mine car slides down and unforeseen circumstances such as distortion, stopped the hidden danger that quilts such as tunnel, installations and facilities, pipeline break, safe reliability is strong; The semicircle energy disperser that the steel rope two ends are provided with can prevent that steel rope from deviating from from wire clips, played good buffer protection effect; When mine car will pass through, the clump weight that only needs pulling stay cord end is pulled to the flexibility net of keeping off a car not hinder the height that mine car passes through and get final product, and after mine car passed through, the flexibility net of keeping off a car can revert to initial equilibrium conditions automatically under the effect of clump weight, work the effect of keeping off a car, simple to operation; In addition, this alley stopping device is simple in structure flexibly, can select wirerope diameter and number of combinations to make the flexibility net of keeping off a car as required arbitrarily, and cost is low, uses leftover pieces to make.
