Description
Technical field
The invention belongs to forest zone cable traction logging technical field, and in particular to a kind of to avoid the light of barrier and grab
The wooden pawl.
Background technique
Winch cable traction logging technology has been widely used in southern abrupt slope forest zone, which is to mitigate work
People's labor intensity improves timber logging production efficiency and plays an important role.If China Patent No. is CN201410402987X
Disclose a kind of method for extending cable logging crane once mounting logging area, comprising the following steps: step 1, with carrying
Rope is projected as central axes perpendicular to the ground, and 20 meters of boundary lines are arranged at each 20 meters of width in central axes two sides；Step 2, two
A standing tree or stump are found on the inside of ten meters of boundary lines；A leading block is arranged in step 3 on standing tree or stump；Step 4 is adjusted
Whole sport car is to appropriate location；Hoisting rope is pulled at the leading block on standing tree or stump, opens leading block manually by step 5
Lock, hoisting rope is packed into pulley groove, and make the outside of hoisting rope end grabbed the wooden hook and be located at leading block, locks lock,
Start 20 meters of boundary lines with the skidding operation of exterior domain.This method is under the premise of meeting safety regulation for operations, to greatest extent
Ground reduces the dismounting number of cable logging crane, time saving and energy saving, can promote and apply in the skidding operation of forest zone.
However, there is also some technical problems urgently to be resolved at present for the logging technology: first is that using cable logging skill
When art carries out logging, obtains and first bundled end of lumber with choker, the hook on winch hauling rope is then caught on into bundle
The wooden rope just can be carried out hauling, operate time-consuming and laborious.Second is that because end of lumber is completely exposed during cable traction logging,
It the blocking of cutting areas barrier such as meets that object contact area is big, therefore is subjected to live standing tree, stump, bushes, earth steps and cannot smoothly drag
It is dynamic.Therefore have to that personnel is sent to follow wood all the way, help to remove barriers, it is not only dangerous to take a lot of work again laborious, it greatly influences to collect
Material production efficiency.To improve forest zone cable logging production efficiency, need a kind of to replace choker and wood capable of being made to avoid automatically
The wood grabber of barrier.
Summary of the invention
It is an object of the invention to be directed to the deficiencies in the prior art, for southern abrupt slope forest zone winch cable traction
Skidding operation provides a kind of not only alternative choker grasping wood, but also can avoid cutting area barrier automatically, realizes smooth logging
Practical wood grabber.
To achieve the goals above, the invention adopts the following technical scheme:
It is a kind of to avoid the light of barrier and grab the wooden pawl, mainly it is made of cage guide cone and lever clamp wood mechanism；The cage
Formula guide cone mainly by large circle, small circle ring and several guide post groups at；The large circle and small circle ring is parallel to each other, and
And guide rod is evenly arranged between large circle and small circle ring, is in cage circular cone columnar structure；The lever clamp wood mechanism is main
It is made of collet, clamp arm, pull ring, pull rod and lever；The medial surface of the collet is equipped with canine tooth and collet is fixedly mounted on
One end of clamp arm, the other end of clamp arm and one end of lever are rigidly connected, and the other end of lever and one end of pull rod are hinged, pull rod
The other end and pull ring one end it is hinged；The junction of the clamp arm and lever is equipped with circular hole；The large circle passes through circle
Hole, it is hinged with clamp arm.
In the present invention, lever clamp wood mechanism is the crossed-symmetrical arrangement using double lever duplex pull rod, can make to press from both sides
Arm and collet obtain enough chucking powers, improve the reliability of present invention grasping wood.Canine tooth is set, collet can be allowed good
Wood is bitten, avoids wood from being detached from during towing and grabs the wooden pawl, further increases the reliability of grasping wood.
The present invention further illustrates that the inner ring of above-described large circle is additionally provided with two struts, and the end of strut
The two sides of large circle Yu clamp arm hinged place are set.Setting strut can effectively provide support force, and lever clamp wood mechanism is avoided to exist
Carry out folder carpentery workshop industry when, large circle stress and deform.
Large circle in the present invention/can be adopted between small circle ring and guide rod, between collet and clamp arm, between clamp arm and lever
It is linked together with welding manner, or other rigid connections can also be used.
The working principle of the invention and application method:
The wooden pawl of grabbing of the invention is connect with winch hauling rope, i.e., is fixedly connected after the hauling rope of winch being passed through small circle ring
(through-hole can be set in the end of pull ring, connect on pull ring convenient for hauling rope), the wooden pawl then will be grabbed by cutting area Field Force
It is pulled to end of lumber, loosens hauling rope, clamp arm is with the hands opened, and collet is clamped into end of lumber, tenses hauling rope, pass through drawing
The boosting function of bar and lever makes both ends collet tentatively clamp wood.Then starting winch recycles hauling rope, further increases
The pulling force of hauling rope, makes collet further clamp wood, until dragging wood is mobile.When wood encounters living stand in dragging process
When the blocking of the barriers such as wood, stump, bushes, earth steps, by large circle, small circle ring and guide post group at conical head
It object contact area is met with minimum by the small circle ring in cone circumvents above-mentioned barrier and passed through.Wood is dragged to
Up to after the predetermined area, winch empties shelves and loosens hauling rope, and wood can be unloaded by manually pulling open clamp arm, then will be grabbed the wooden pawl and be taken down
The end of a piece wood is clamped, repeat the above steps carry out next period grab the wooden skidding operation.
Advantages of the present invention:
1. design is scientific and reasonable for structure of the invention, it is simple and practical, can effectively reduce winch cable traction logging during
Support staff can not only save labour, reduce cost of labor, but also can greatly improve cable logging efficiency, will be to winch
Important facilitation is played in the popularization and application of cable logging technology.
2. the present invention uses double lever duplex pull rod force-increasing mechanism arranged in a crossed manner, clamp arm and collet is made to obtain enough clampings
Power improves and grabs the reliability that the wooden claw clip holds wood.
3. the present invention will grab the wooden pawl Design of Main Structure into cage pyramidal structure, it can not only mitigate own wt convenient for taking
Band, and being acted on by the guiding of special pyramidal structure and the minimum evacuation for meeting object contact area makes to grab the wooden pawl to have and keep away automatically
Allow barrier function.
