Abstract
The utility model discloses an over-speed protection device for a mine car in a mine inclined roadway, which comprises an over-speed triggering mechanism, a hanging connection device and a car stopping device; the over-speed triggering is connected with the top part of the car stopping device in a hanging manner by the hanging connection device. The over-speed protection device has simple structure and convenient use. When the mine car passes through below the over-speed triggering mechanism, if the mine car runs with over speed, the over-speed triggering mechanism is triggered and is led to automatically remove the connection with the car stopping device, and then the car stopping device falls off on the ground of the inclined roadway so as to stop the mine car in time and prevent harm brought by the over-speed of the mine car.
Description
Technical field
The utility model relates to a kind of mine inclined anti-mine car overdrive.
Background technology
Mine inclined range of lift is longer, and working link is more, if wire rope breaking takes place in the operational process of inclined gallery mine car, out of control mine car will be at full speed goes and the sport car phenomenon occurs to downslide, and is abnormally dangerous.For effectively preventing the sport car phenomenon, just need when overrunning, mine car in time it be blocked exactly.But the anti-overdrive of mine car does not appear in the market.
The utility model content
Technical problem to be solved in the utility model provides a kind of mine inclined anti-mine car overdrive, can in time mine car be blocked when mine car is overrun.
For solving the problems of the technologies described above, mine inclined anti-mine car overdrive of the present utility model includes the trigger mechanism of overrunning, hangs connecting device and alley stopping device, and the trigger mechanism of overrunning is hung with the alley stopping device top and is connected by hanging connecting device.
As a kind of improvement of the present utility model, the described trigger mechanism of overrunning includes the frame that is connected in the top, tunnel, the upper end that the frame lower surface is positioned at a higher side in tunnel and a drive link is hinged, the opposite side of frame lower surface vertically is inserted with safety plug, and the length of drive link is greater than the distance of drive link pin jointed end and safety plug bottom; Safety plug with hang connecting device and be connected.
As further improvement of the utility model, the described connecting device of hanging includes hanging rope and is connected in the pulley at top, tunnel, and hanging rope one end cover is hung on the safety plug, and the other end of hanging rope is hung with the alley stopping device top after by pulley and is connected.
As further improvement of the utility model, described alley stopping device is a car stopping rod; Described pulley series connection is provided with two.
As further improvement of the utility model, described hanging rope is a steel rope.
The utlity model has following advantage:
1. the sense of motion along mine car in the tunnel when the utility model uses is arranged, the trigger mechanism of overrunning is hung and is connected and alley stopping device is suspended in the top, tunnel by hanging connecting device and alley stopping device top, mine car by trigger mechanism when below of overrunning if the phenomenon of overrunning, automatically terminate after the trigger mechanism of the overrunning action and being connected of alley stopping device, make alley stopping device fall to ground, tunnel, thereby can in time block mine car.
2. the trigger mechanism of overrunning is simple in structure, easy to use, and cost is lower.
3. the hanging rope one end cover of hanging in the connecting device is hung on the safety plug, and the other end of hanging rope is hung with the alley stopping device top after by pulley and is connected and alley stopping device is suspended in tunnel top, and such being provided with is simple and reliable.Mine car can collide drive link by time below the utility model, and when mine car speed was not high, the amplitude of fluctuation of drive link was limited, can not clash into safety plug; When mine car was overrun, the drive link amplitude of fluctuation was big, and safety plug is subjected to upspringing behind the bump of lever, and the hanging rope that cover hangs on the safety plug is just thrown off automatically, thereby had discharged the alley stopping device of hanging rope other end suspention.
4. hanging rope adopts steel rope, and cost is lower, hangs firmly.
Description of drawings
Fig. 1 is car stopping rod structural representation of the present utility model when not falling;
Fig. 2 is that car stopping rod falls back structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, mine inclined anti-mine car overdrive of the present utility model includes the trigger mechanism of overrunning, hangs connecting device and alley stopping device.Hang the pulley 2 that connecting device includes hanging rope 1 and is connected in the top, tunnel; Alley stopping device is a car stopping rod 3; The trigger mechanism of overrunning includes frame 4, drive link 5 and the safety plug 6 that is connected in the top, tunnel, the upper end that frame 4 lower surfaces are positioned at a higher side in tunnel and a drive link 5 is hinged, the opposite side of frame 4 lower surfaces vertically is inserted with safety plug 6, and the length of drive link 5 is greater than the distance of drive link 5 pin jointed ends and safety plug 6 bottoms.Hanging rope 1 one end covers are hung on the safety plug 6, and the other end of hanging rope 4 is hung by pulley 2 back and car stopping rod 3 tops and is connected and car stopping rod 3 is suspended in above the tunnel.Wherein, pulley 2 can be connected as shown in Figure 1 and is provided with two, also can be arranged to one or the series connection be provided with a plurality of.
When mine car 7 moves, no matter uply or descending all can collide drive link 5 in mine inclined.Mine car 7 speed of a motor vehicle are hour less to the impulsive force of drive link 5, after drive link 5 is stressed amplitude of fluctuation limited, can not clash into safety plug 6; When mine car is overrun, drive link 5 is subjected to bigger impulsive force, amplitude of fluctuation is big, safety plug 6 is subjected to popping up behind the bump of drive link 5, the hanging rope 1 that cover hangs on the safety plug 6 is just thrown off automatically, thereby discharged the car stopping rod 3 of hanging rope 1 other end suspention, blocked the down going channel of mine car 7 after car stopping rod 3 falls, thereby in time block mine car 7.
