The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The formation and the quiescence thereof of the anti-automatic alley stopping device of sport car of the utility model have been shown among Fig. 1,2.This alley stopping device mainly is made of swinging gear, the mechanism of keeping off a car, leading sheave (5) and steel rope (3).
Swinging gear is by axle (6), swing span (7), holder rope sheave (4), active fork formations such as (10).Its structure is close with melon formula stop buffer, can be along the swing of mine car service direction but it does not work the effect of keeping off a car; Under the action of gravity of hoisting cable, one square neck is oblique to the down-hole.Swinging gear adopts cross weight hammer type tumbler structure; That is: swing span (7) connects firmly one, is criss-cross and connects with axle (6).Swing span (7) bottom is provided with counterweight, makes center of gravity be positioned at the bottom, can be with axle (6) around axis swing, and when static, swing span (7) is erectility.The top of swing span (7) is provided with the holder rope sheave (4) of rotation.One end of axle (6) stretches out track (13), and axle head is installed initiatively fork (10).Axle (6) is by the bearing block support that is fixed on the base (11).Swinging gear adopts the base (11) of fixed link framed structure, and base (11) is fixed on the interior sleeper of track (13), is higher than track 0.2m and vertical with track (13).Track (13) has swinging gear work nest (8), and the lower part of swinging gear places in the work nest (8).
Swinging gear is positioned at the top of the mechanism of keeping off a car, spacing (the L)＞distance of swing span (7) from bottom position to reseting period mine car sport car of the two.This device is applicable to the inclination angle greater than the upper and lower mountain of exploiting field rail transport more than 7 ‰, and the inclination angle, tunnel is during less than 12 °, and spacing (L) is: 20～25m; The inclination angle, tunnel is during greater than 12 °, and spacing (L) is: 25～30m.The holder rope sheave (4) of swinging gear plays the holder hoisting cable, and keeps off a car automatically by the pressure and the Tension Control of hoisting cable, so the utility model claims " rope pressure type alley stopping device " again.
Keep off a car mechanism comprise stop buffer (2) and the axle on driven fork (1).The two melon formula stop buffers of stop buffer (2) employing standard are transformed, and model can be selected A, B, C type for use, can form the product of different size respectively according to different places to use.Remodeling method is, with the end lengthening of the axle of stop buffer, stretch out outside the track, in axle head driven fork (1) is installed.
The mode that installs and fixes of mechanism of keeping off a car is identical with swinging gear, and the base of its fixed link framed structure (12) is fixed on the interior sleeper of track (13), is higher than track 0.2m and vertical with track (13), and track (13) has the mechanism's work nest (9) of keeping off a car.
Fig. 4,6 shows the steel rope (3), leading sheave (5) of interlock usefulness, the connection structure of fork (10) initiatively.Steel rope (3) or title oil thread rope, its lower end connects with the driven fork (1) of the mechanism of keeping off a car, and after the leading sheave (5) that is located at swinging gear axle top is walked around in its upper end, connects with the active fork (10) of swinging gear.By steel rope (3) and leading sheave (5), initiatively interlock between fork (10) and the driven fork (1), and then make the swinging gear and the mechanism of keeping off a car realize interlock.Leading sheave (5) is supported by its bearing seat (14).Initiatively fork (10) and driven fork (1) also can adopt the driving and driven STATEMENT OF FEDERALLY SPONSORED of other form to substitute, as: adopt driving and driven swing pulley.
Principle of work:
Operating state when Fig. 3,5 illustrates the utility model driving.Normally drive a vehicle with V
0Operation.
When mine car was up, through swinging, consistent with the service direction of mine car, mine car two mechanisms later reverted to normally open immediately with mine car for the mechanism of keeping off a car of this alley stopping device, swinging gear, does not influence normal lifting transportation.The normally open state of promptly keeping off a car, the closed condition state of promptly letting pass.
When mine car was descending, swinging gear is with the operation of mine car, swing downwards, and was consistent with the mine car service direction, after the mine car, under the effect of hoisting cable tension force and gravity, keep closed condition, interlock simultaneously keep off a car mechanism action, become closed condition by often opening; After the parking lot was transferred in the normal operation of mine car, swinging gear returned to normally open immediately under the effect of its swing span (7) counterweight, and the mechanism of keeping off a car of interlock simultaneously resets.
Install when above when mine car operation is positioned at this, if the mine car derailing accident takes place, mine car is with speed V
1Operation downwards, after mine car was crossed swinging gear, owing to there is not the pressure of hoisting cable, swinging gear was at t
1Time in reset rapidly, the mechanism of keeping off a car simultaneously is in normally open.Mine car is with V
2Speed is at t
2Time in, quicken to run to when keeping off a car mechanism, because spacing (the L)＞distance of swing span (7) of swinging gear and the mechanism of keeping off a car, so t from bottom position to reseting period mine car sport car
2＞t
1, mine car is blocked operation, thereby has played the effect of keeping off a car.
