Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
Embodiment 1
Fig. 1 is the one-tenth block coal shovel excavating impulsion shovel guiding device described in embodiment 1.This device comprises the holder 11 being arranged on excavating impulsion shovel guide peg 7 outside.The front end of excavating impulsion shovel guide peg 7 is fixedly connected with excavating impulsion shovel 1, rear end is connected with drive unit, the front portion of excavating impulsion shovel guide peg 7 is provided with guide ring fixed head, guide ring fixed head comprises guide ring upper mounted plate 6 and guide ring bottom plate 9, wherein guide ring upper mounted plate 6 is arranged on the top of excavating impulsion shovel guide peg 7, guide ring bottom plate 9 is arranged on the below of excavating impulsion shovel guide peg 7, and guide ring upper mounted plate 6 is fixedly connected with holder 11 respectively by adpting flange 2 with guide ring bottom plate 9.The guide ring 3 that two axially spaced-aparts along excavating impulsion shovel guide peg 7 are arranged is provided with between guide ring upper mounted plate 6 and guide ring bottom plate 9, guide ring 3 is fixed on guide ring upper mounted plate 6 and guide ring bottom plate 9, and guide ring 3 is enclosed within the outside of excavating impulsion shovel guide peg 7.The thickness of guide ring 3 is not more than the diameter of excavating impulsion shovel guide peg 7, to ensure the guide effect of this guiding device.Guide ring 3 can be made up of hard materials such as carbide alloy, high-speed steel, tool steel or graphite materials, to improve the abrasion resistance of guide ring.The inner surface of guide ring 3 is provided with trapped fuel groove 4, has lubrication oil in trapped fuel groove 4, and when excavating impulsion shovel guide peg 7 drives excavating impulsion shovel 1 reciprocating impact to move, lubrication oil can reduce the friction between guide ring 3 and excavating impulsion shovel guide peg 7.The rear portion of excavating impulsion shovel guide peg 7 is provided with stop nut 8, to limit the stroke of excavating impulsion shovel 1 ballistic motion forward.
Excavating impulsion shovel guide peg 7 between guide ring upper mounted plate 6 and guide ring bottom plate 9 is provided with chute 10, and chute 10 is arranged along the axis of excavating impulsion shovel guide peg 7, and the length of chute 10 is greater than the impact stroke of excavating impulsion shovel.Corresponding is fixed with anti-turn bolt 5 between guide ring upper mounted plate 6 and guide ring bottom plate 9, the two ends of anti-turn bolt 5 are separately fixed on guide ring upper mounted plate 6 and guide ring bottom plate 9, and anti-turn bolt 5 is through the center of excavating impulsion shovel guide peg 7, and can slide along the chute 10 on excavating impulsion shovel guide peg 7.Spacing between two guide rings 3 is not less than the length of chute 10.
During the work of this device, first, when drive unit drives excavating impulsion shovel 1 to do front-rear reciprocation movement, when in excavating impulsion shovel 1 ballistic motion process forward, excavating impulsion shovel 1 realizes impact coal breakage to ore bed and clear face by the long teeth of the alternate layout of length and short teeth, and the punching of teeth head is cut and utilized teeth side to rush while sword impacts coal breakage to cut sword and mining face cleared up by side cutting edge, then, when excavating impulsion shovel moves backward, punching is shoveled and retracts, realize reciprocating impact next time.In the process that excavating impulsion shovel seesaws, serve support guide effect by guide ring 3, guide ring upper mounted plate 6 and guide ring bottom plate 9 pairs of excavating impulsion shovels 1 and excavating impulsion shovel guide peg 7, anti-turn bolt 5 can avoid excavating impulsion shovel guide peg 7 and excavating impulsion shovel 1 to rotate.When the stop nut that excavating impulsion shovel 1 moves forward on excavating impulsion shovel guide peg 7 contacts with holder 11, excavating impulsion shovel 1 cannot move forward, and now excavating impulsion shovel 1 is retracted under the induced effect of drive unit, thus realizes reciprocating impact next time.
In the present embodiment, the inner surface of described guide ring 3 can be inlaid with the hard materials such as carbide alloy, high-speed steel, tool steel, graphite material, in order to improve the abrasion resistance of guide ring 3 inner surface.Guide ring 3 can be integral structure with guide ring upper mounted plate 6 and guide ring bottom plate 9.The guide ring 3 of greater number also can be set in this device.
Embodiment 2
Fig. 2 is the one-tenth block coal shovel excavating impulsion shovel guiding device described in embodiment 2.As different from Example 1: one end of anti-turn bolt 5 is fixed on guide ring upper mounted plate 6, the other end, through the center of excavating impulsion shovel guide peg 7, slides along the chute 10 on excavating impulsion shovel guide peg 7, is not fixed on guide ring bottom plate 9.
In addition, described anti-turn bolt 5 also can only be fixed on guide ring bottom plate 9, and the other end through the center of excavating impulsion shovel guide peg 7, and can slide along the chute 10 of excavating impulsion shovel guide peg 7.
The other the same as in Example 1.
Embodiment 3
Fig. 3 is the one-tenth block coal shovel excavating impulsion shovel guiding device described in embodiment 3.As different from Example 1: be axially arranged with chute 10 along excavating impulsion shovel guide peg 7 on described guide ring upper mounted plate 6 and guide ring bottom plate 9, now anti-turn bolt 5 is fixed on excavating impulsion shovel guide peg 7, anti-turn bolt 5 can slide in the chute 10 of guide ring upper mounted plate 6 and guide ring bottom plate 9, drives excavating impulsion shovel guide peg 7 to slide along chute 10 simultaneously.
Described anti-turn bolt 5 also can with excavating impulsion shovel guide peg 7 in integral structure.
The other the same as in Example 1.
