Description
Technical field
The utility model belongs to design and the manufacturing technology field of the anti-race device of narrow gauge slope vehicle.
Background technology
Narrow gauge slope vehicle travels in orbit all without anti-race device at present.When so-called anti-race refers to narrow gauge slope vehicle along the acclive rail running of tool, its haulage cable is pulled off for a certain reason, and do not allow mine car bolt along down ramp, with the brake of related device buffering.Thereby prevent the generation of equipment or fatal accident.As mentioned above, narrow gauge slope vehicle is general without anti-race device at present.
Summary of the invention
The purpose of this utility model is to provide narrow gauge slope vehicle anti-race device.
Its technical scheme is: be made up of the contact mechanism on controlling machine and railway roadbed on mine car.
Control mechanism: be welded with two of left and right on the buffing pad of mine car and support otic placode, the axle at eccentric shaft two ends is put in the hole of otic placode.Eccentric shaft is equipped with left and right claw hook, positioning ring is fixed on claw hook left and right.Pusher dog wheel is equipped with in axle one end, is fixed by locking key and keyway.Pin-and-hole in buffing pad is inserted with hauling rope latch, and on this latch, cover has haulage cable.Eccentric shaft vertex stage casing is plane, is called vertex plane, coordinates with the contraposition of hauling rope latch.
Contact mechanism: contact case is welded on base plate, has upper and lower side respectively through the flexible contact stem of upper cover and base plate in contact case, contact stem cover has spring, spring lower end to be fixed on base plate, and base plate is bolted on railway roadbed.
Principle of work of the present utility model and using method:
Principle of work: in the time that hauling rope latch is subject to rope traction, pin body can abut against on the facet of eccentric shaft, claw hook on eccentric shaft is tightly withstood on buffing pad bottom surface, when mine car passes through contact mechanism on ramp, because tractive force is considerably beyond the elastic force of contact, pusher dog on pusher dog wheel can be oppressed the contact stem of contact mechanism and be retracted downwards, and in the situation that eccentric shaft action does not occur, mine car passes through contact mechanism; When drawing, latch loses traction state (while breaking rope sport car) towing pin and eccentric shaft can produce loosening or gap, eccentric shaft can be under contact effect, along with pusher dog wheel clickwise, eccentric moves on to below by horizontal surface center, produces very large gap with towing pin.Now the eccentric of eccentric shaft can be under eccentric Action of Gravity Field, is automatically slipped to the below of axle.Claw hook, under own wt nutating action, is fallen nadir and is started to arrest.When mine car moves on level line, when particularly empty wagons go-cart moves, because hauling rope latch is near the plane of eccentric vertex, control eccentric falls, and forces the cambered surface of claw hook to abut against on the bottom surface of buffing pad, and eccentric shaft drives the turning radius of claw hook, be greater than the distance between axle center and buffing pad bottom surface, therefore the pawl point of claw hook is more sagging, and it is tighter that cambered surface and buffing pad bottom surface can be leaned on, so there will not be to fall pawl phenomenon to occur.
Using method, contact mechanism is contained on the middle section or section on the lower side of inclined shaft railway roadbed, contact stem and pusher dog wheel will be on same line of centerss, contact and pusher dog will be adjusted collapsing length, in the time that mine car passes through contact mechanism, the pusher dog of control mechanism is depressed contact stem can make control mechanism not work, and mine car passes through smoothly.Control mechanism on mine car, under the hauling rope latch effect being subject to after tractive force, firmly withstands on the bottom surface of mine car buffing pad the cambered surface of two claw hooks on eccentric shaft, makes claw hook and tramcar chassis keeping parallelism state.No matter mine car upstream and downstream, claw hook can not fall to arresting.Once the disconnected rope of winch, mine car loses traction meeting and bolts to down-hole along track, there is gap in the hauling rope latch and the eccentric shaft that lose traction, in the time that the contact of contact mechanism is encountered the pusher dog of pusher dog wheel, contact can be stirred pusher dog wheel clickwise, drive the eccentric of eccentric shaft to be rotated down, now the eccentric of eccentric shaft loses the control of traction latch, under the effect of laying particular stress on, be slipped to axle below, two claw hooks also fall thereupon, and under own wt effect, be automatically slipped to nadir, the bill of claw hook can catch on sleeper, along with mine car is to underground moving, due to sleeper and railway roadbed friction force very big, mine car is slowly stopped, realize the anti-race of buffer-type.
The utility model has the advantages that structure is tight, stable and reliable for performance, easily manufacture, easy to use, has good economic benefit and social benefit.
