Abstract
The utility model relates to a mine round link chain clipping device which can be used for shearing other round link chains, bar stocks, bolts, etc. The mine round link chain clipping device is composed of a U-shaped block, a cylinder part, a shearing tool, etc. and uses a separate type structure. The utility model has the advantages of convenient transportation and simple operation. The service life of the shearing tool is as long as more than 50 times shearing, and one mine round link chain can be sheared within 15 minutes. The utility model overcomes the defects of large labor strength of a manual saw, low efficiency, and poor safety conditions for flame cutting.
Description
The utility model relates to a kind of circle chain of mine service kit, can be used for shearing circle chain of mine, also can be used for shearing other round-link chains, bar, bolt etc.
In coal production, mining face under mine needs circle chain of mine is disconnected when handling the chain rupture fault or adjusting scraper chain length.Circle chain of mine adopts high strength alloy steel, and heat treatment hardness is higher, has in the down-hole under the specific condition of requirement of explosion proof, and chain rupture has certain difficulty.Understand according to us, present domestic coal master will adopt manual sawed-off, and some low gaseous mine adopts is strengthening flame cutting under the ventilation condition.Flame cutting safety condition is poor, and has increased the ventilation expense.The hand saws labor strength is big, and efficient is low, and sawed-off φ 30 * 108 circle chain of mine need 2 hours approximately.Along with the development of fully-mechanized mining working, circinal loop chain in large specification in use for mine is used more and more widely aborning, and the hand saws difficulty will be bigger.The chain rupture difficulty is restricting the raising of coal production efficient.
Newly find following three kinds of utility model patents and a scientific and technological achievement through looking into:
Patent 2 multi-functional hand cutter Chinese patents 96242696
Achievement JL-30 type circle chain of mine cutter Chinese science and technology achievement 90208516
The object that is sheared that first three piece content is related is mainly steel plate, round steel, steel wire rope etc., and hardness is low, and intensity is little, and required shearing force is less.The 4th piece of scientific and technological achievement of finishing for our unit is sheared object and is mainly circle chain of mine, but it adopts and squeeze scissors shearing mechanism (see figure 10), and need cut off circle chain of mine two straight flanges respectively could chain rupture, and efficient is low; Cutter life is lower; Change cutter and must dismantle oil cylinder.
The purpose of this utility model is to provide a kind of circle chain of mine shearing equipment.Once shear and to realize chain rupture, shear φ 30 * 108 circle chain of mine and need 15 minutes approximately, and hand saws needs 2 hours approximately, shortened greatly and handled the chain rupture required off-time of fault.The shearing tool life-span reaches more than 50 shearings, has satisfied the requirement of using, and has solved low this technical barrier of cutter life.

Among the figure: 1-screw rod, 2-U shape piece, 3-be cutter head, the movable cutter head of 4-, 5-oil cylinder, 6-piston, 7-Si Lai Quan, 8-Glais ring, 9-cylinder bottom, 10-card key, 11-porous plug, 12-alignment pin, 13-circle chain of mine fixedly
Below in conjunction with description of drawings the utility model.
The circle chain of mine cutter adopts handlance to make high-voltage power supply, hydraulic coupling acts on movable cutter head 4 by piston 6, circle chain of mine 13 1 straight flanges between the cutter head 3 and movable cutter head 4 cut a breach with placing fixedly, notch length is greater than circle chain of mine 13 straight flange diameters, from then on breach will be sheared circle chain of mine 13 and the disengagement of adjacent round-link chain, continuous chain is disconnected, convenient maintenance and replacing.
The circle chain of mine cutter adopts split-type structural, is made of U-shaped piece 2 and oil cylinder 5 parts.Can separately carry assembling uses.During assembling oil cylinder 5 coupling parts are put into U-shaped piece 2 breach, with respect to U-shaped piece 2 half-twists, alignment pin 12 automatic positioning instants can.After the use alignment pin 12 is lifted, U-shaped piece 2 can be thrown off U-shaped piece 2 and oil cylinder 5 with oil cylinder 5 relative half-twists.(seeing Fig. 1,2,3)
One trapezoidal thread hole is arranged at U-shaped piece 2 bottoms, piston 6 can be resetted by the screw rod 1 that rotates in this hole.U-shaped piece 2 and oil cylinder 5 coupling parts adopt the circle-arc tooth engaging structure.(seeing Fig. 4,5)
A screwed hole that is used to assemble porous plug 11 is arranged on oil cylinder 5 walls, and cylinder tube and cylinder bottom 9 are assembled together by circular card key 10.Sealing between oil cylinder 5 and the piston 6 is adopted and is enclosed the combination sealing that 7 guidance tapes constitute by Glais ring 8 sealing rings and Si Lai.(seeing Fig. 6,7)
Adopt pure shear formula shearing mechanism (seeing Figure 11), shear two sections simultaneously, spacing is d+3mm, (wherein d is for being sheared round-link chain 13 straight flange diameters), the cutter blade adopts and is sheared the arc surface structure that the object diameter is complementary, and the arc surface cornerite is 90 °.Shearing force is distributed on the whole arc surface, the stressed symmetry of cutter, and cutter is difficult for taking place damages such as tipping, conquassation, cutter life height.Fixedly cutter head 3 and movable cutter head 4 front ends have targeting part, guarantee shear gap.Movable cutter head 4 rear ends are useful on the step axle that connects with piston 6, and movable cutter head 4 coupling parts are put into piston 6 stepped holes and half-twist can be connected to together with piston from the oil cylinder front end, need not dismantle oil cylinder.Fixedly cutter head 3 is put into from U-shaped piece 2 openends, locatees automatically on U-shaped piece 2 by following outstanding step.(seeing Figure 12,13,14,15)
