Description

Round-link chain hydraulic safe clipper

Technical field

The utility model belongs to the hydraulic cutter facility, is mainly used in round-link chain is sheared.

Technical background

Drag conveyor is one of the main transporting equipment in mine, and its driving component is to connect the round-link chain that forms by some annular chain links.In order to adapt to the variation of mining geology condition and delivered length, drag conveyor traction chain link needs lengthening sometimes or shortens.Haulage chain lengthening or shorten except that carrying out with the adjusting chain needs sometimes chain link blocked and carries out.At present, the method for blocking chain link mainly still adopts artificial sawed-off method.Because the material of chain link is the very high alloy of hardness, the complex environment in mine in addition, so with artificial when sawed-off, efficient is low, dangerous, labour intensity is big.For example, a sawed-off φ 30mm chain link, two workmans need nearly two hours time, have seriously influenced mine production.Therefore, in order to shorten time to chopping or to reduce labour intensity, the colliery that has even pound or gas cutting blocks, the serious safety in production that is threatening the mine with hammering into shape.

Summary of the invention

The purpose of this utility model is a kind of safe and reliable, labour intensity is little, efficient is high and easy to operate round-link chain hydraulic safe clipper of design.

The structure of clipper is: it comprises anchor clamps, be processed with draw-in groove, chain annular groove, moving knife gathering sill and quiet cutter gathering sill on the anchor clamps, card has the hydraulic cylinder that has flange in the draw-in groove, plunger is arranged in the hydraulic cylinder, the left end of moving knife links by the right-hand member of backhaul dish and plunger, then hydraulic cylinder is snapped in by its flange in the draw-in groove of anchor clamps, moving knife is put into the moving knife gathering sill of anchor clamps, and quiet cutter is put into the quiet cutter gathering sill of anchor clamps.

During use, the chain link that will be cut is put into the chain annular groove earlier, injects highly pressurised liquid again in cylinder body, and under the effect of hydraulic coupling, plunger promotes moving knife and moves, and cooperates the formation shearing force that round-link chain is cut off with quiet cutter.

Its good effect is:

1, adopt this device after, no longer use artificial sawed-off round-link chain, and only round-link chain cut off with the effect of hydraulic coupling, safety, reliable, save time, laborsaving.For example, the chain link of cutting off a diameter and be 30mm only needs 5 minutes, than surplus having improved 20 with artificial sawing times, and has alleviated working strength of workers greatly.

2, anchor clamps and cylinder body connect by draw-in groove and flange circumference, and not only bearing capacity is big, and simplifies the structure, reduced cost;

3, the backhaul dish is housed on plunger, had both guaranteed the backhaul of moving knife, mutually noninterfere when plunger is rotated.

The specific embodiment

Now in conjunction with the accompanying drawings concrete enforcement of the present utility model is described:

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, it mainly is made up of cylinder body 1, plunger 2, anchor clamps 16, moving knife 14, quiet cutter 15, fairlead 9 and backhaul dish 12 etc.During assembling, guide ring 3,5 and cydariform sealing ring 4 are enclosed within the left end of plunger 2, again plunger 2 are put into cylinder body 1; After loading onto O-ring seals 6,7 and dust ring 10 on the fairlead 9, be sleeved on the right-hand member of plunger 2, and plunger be fixed on the cylinder body 1 with screw 8, the right-hand member of the left end of moving knife 14 by backhaul dish 12 and screw 11 and plunger 2 linked.Then, cylinder body 1 is snapped in by its flange in the draw-in groove s of anchor clamps 16, moving knife 14 is put into the square cutter groove a of anchor clamps 16, and quiet cutter 15 is put into the square cutter groove c of anchor clamps 16, the limit that is sheared of being cut chain link d is put among the square chain annular groove b again.

As Fig. 5, Fig. 6 and shown in Figure 7, the cutter hub of moving knife 14 is a square structure, and left end is rounded, and the right-hand member cutter head is a wedge structure, is cut the chain loop contacts with quilt, and tail end is the plane that contacts with plunger 2; The cutter head of quiet cutter 15 left ends is a wedge structure, and cutter hub is a square structure, and right-hand member is the plane that contacts with anchor clamps 16;

As Fig. 8 and shown in Figure 9, the backhaul dish is a dissection type loop configuration.Be processed into schematic structure before the processing earlier, and then cut open along the F-F face.During installation, earlier the left end of moving knife 14 is put into the right-hand member groove of plunger 2, again two semi-rings of backhaul dish 12 are sleeved on the moving knife, be fixed on the plunger with screw 11 then.

The using method of present embodiment:

1, before the shearing chain link, earlier protective cover 13 is taken off, chain annular groove b is put on the limit that is sheared of the chain link d that shear, and then cover protective cover;

2, tubing interface e and f and hydraulic pump are connected;

3, the reversal valve of hydraulic pump is got to the oil-feed position, shake the handle of hydraulic pump, hydraulic oil enters the g chamber of hydraulic cylinder, under the effect of hydraulic coupling, plunger is overhanging, promotes cutter 14, last under the acting in conjunction of moving knife 14 and quiet cutter 15 shearing forces, the chain link d that shear is cut off;

4, after chain link d is cut off, again the reversal valve of hydraulic pump is got to the oil return position, shake the handle of hydraulic pump, hydraulic oil enters the h chamber of hydraulic cylinder, and under the effect of hydraulic coupling, plunger is withdrawn, and returns by backhaul dish 12 drive moving knife 14;

5, take off protective cover, the upset chain link is put into chain annular groove b to the opposite side of chain link d, and then is covered protective cover;

6, repeating step 3 and 4 operation are cut off the opposite side of chain link d and cutter 14 are return.
