The winch machine provided by the utility model overcomes the disadvantages of the existing winch machine, and can well adapt to the actual condition of the wood production operation in current forest zones, has the overload protection function and orderly rope arranging function; and moreover, the security of the winch machine used for forestry is enhanced at the same ofwhile prominently improving the skidding operation efficiency in the forest zones is improved prominently.
Description
Technical field
The utility model relates to a kind of forestry machinery for forest operation and orest management, relates in particular to a kind of forestry skidding machinery that twists collection to interspersing among former of operating location or log after the timber production operation that can be used in.
Background technology
At present, Northeast Forest Areas forestry with yarder be mostly by original large-scale log tractor such as the machineries such as J-50, J-80 with the capstan engine repacking, these large-scale capstan enginees can not adapt to existing timber production operation condition.The at present timber production operation of Northeast Forest Areas has that operating location disperses, the gradient is large, forest is sparse, the equal new characteristics such as lower of hectare logging amount and higher mill run.If continue to adopt original large-scale capstan engine, will produce " cart draws little goods " phenomenon, cause the wasting of resources.
In the course of the work, forestry also is faced with various problems with capstan engine.Because the Northeast's timber production operation concentrates on winter mostly, thereby former or log often are frozen in the soil.When adopting capstan engine to carry out logging, can produce larger impact to capstan engine.In addition, in the process of capstan engine, they often run into the interference of cutting down rear remaining stump, stub or being subject to other deadwood foreign material etc. at former or log collection, block easily the timber of strand collection, cause capstan engine to produce " vexed car " phenomenon, make capstan engine be in a kind of serious " overload " state.This overload phenomenon is very large to the infringement of capstan engine driving engine, or even destructive, and in case the generation overload is stopped to adjust and expended time in very much, this has also had a strong impact on logging efficient.
Forestry is that steel rope twines easily with another persistent ailment of capstan engine, is easy to fracture.Forestry with capstan engine in the course of the work, steel rope is easy to twine at the capstan engine reel uneven, the phenomenons such as rope, disorder cable appear stinging, this can cause the damage that steel rope is too early, potential safety hazard occurs easily, in case steel rope weares and teares suddenly, the rope body disconnects capstan engine moment generation impulsive force, cause easily log tractor moment preshoot, the steel rope that flies that jumps hurts workman and forest on every side easily.
Therefore, need to explore the novel forest zone that is more suitable for and produce actual small-sized, safe yarder.
Summary of the invention
Based on the existing problem of above-mentioned prior art, the utility model is that a kind of small-sized, safe New Forestry yarder will be provided.This capstan engine has overcome the existing deficiency of existing capstan engine; can adapt to preferably current forest zone timber production operation actual condition; have overload protection function and arrange in order the rope function, when significantly improving forest zone skidding operation efficient, strengthened the safety performance of forestry with capstan engine.
This New Forestry yarder provided by the utility model mainly comprises the parts such as overload protective device, driving gear, ring gear, messenger chain, retarder, reel, drum shaft, shift fork, power-transfer clutch, rope processing device and steel rope.

Among the figure: 1. retarder 2. drum shaft 3. steel ropes 4. reels 5. draw-in grooves 6. shift forks 7. splines 8. bodies 9. power-transfer clutchs 10. are pressed rope roller 11. springs 12. anchor fittings 13. driving gears 14. tractor rear axle power take-off shafts 15. messenger chains 16. ring gears 17. overload protective devices 18. worm gears 19. reducer shafts 20. pressurization disk 21. latch segments 22. friction linings 23. belleville springs 24. setting nuts 25. axle sleeves
The specific embodiment
1 to 4 pair of present embodiment describes by reference to the accompanying drawings.Power take-off shaft 14 at the log tractor back axle is installed driving gear 13 and overload protective device 17.Utilize the position of 24 pairs of latch segments 21 of setting nut of overload protective device 17 to regulate, and then belleville spring 23 is exerted pressure, again pressure is passed to pressurization disk 20.Pressurization disk 20 passes to friction lining 22 to pressure again, makes friction lining 22 and driving gear 13 close contacts.
When the operation of the driving engine of trac., power take-off shaft 14 transmission of power to overload protective device 17.By the friction lining 22 of overload protective device 17 and the rubbing effect between the driving gear 13, transmission of power is to driving gear 13.13 of driving gears by messenger chain 15 transmission of power to ring gear 16.Ring gear 16 to reducer shaft 19, is carved with screw thread to transmission of power above the reducer shaft 19, meshes with worm gear 18, and transmission of power to worm gear 18, and realize is slowed down.Reducer shaft 19 and worm gear 18 consist of retarder 1 together.Worm gear 18 turning handle transmission of powers are to drum shaft 2, and band dynamic clutch 9 rotates.Power-transfer clutch 9 is connected with drum shaft 2 by spline, and can carry out sway in the spline 7 on drum shaft 2.6 of shift forks are used for control clutch 9 in the sway of spline 7, so the combination of control clutch 9 and reel 4 with separate.When power-transfer clutch 9 and reel 4 in conjunction with the time, power-transfer clutch 9 can be stuck in draw-in groove 5 the insides on the reel 4, power then is delivered to reel 4, band movable reel 4 rotates, simultaneously control is wrapped in steel rope 3 operations on the reel 4.When power-transfer clutch 9 separated with reel 4, reel 4 did not rotate.
When steel rope 3 operation, the pressure rope roller 10 of rope processing device is under the elastic force effect of spring 11, be pressed in tightly above the steel rope 3, guarantee that steel rope 3 can carry out in order rope closing and put rope, prevent that steel rope 3 from twining uneven at capstan engine reel 4, occur stinging the phenomenons such as rope, disorder cable, improved simultaneously logging efficient.
In the process of former of capstan engine strand collection or log, if run into the interference of cutting down rear remaining stump, stub or being subject to other deadwood foreign material etc., when making capstan engine be in a kind of serious " overload " state, driving gear 13 imposes on the reaction torque of friction lining 22 will be greater than the nominal torque of friction lining 22, then can produce relative sliding between driving gear 13 and the friction lining 22 this moment, power will can be by effective communication, thereby guaranteed that also capstan engine can not produce " vexed car " phenomenon, can not produce infringement to output shaft of tractor rear axle.
The above; be the better specific embodiment of the utility model; protection domain of the present utility model is not limited to the listed specific embodiment; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
