Description
Technical field
The utility model belongs to forest zone cable traction logging technical field, and in particular to a kind of cutting area logging is with grabbing wood
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.
Utility model content
The purpose of this utility model is that the deficiencies in the prior art are directed to, for southern abrupt slope forest zone winch cable
Hauling operation provides a kind of not only alternative choker grasping wood, but also can avoid cutting area barrier automatically, realizes smooth collection
The practical wood grabber of material.
To achieve the goals above, the utility model uses following technical scheme:
A kind of cutting area logging is mainly made of cage guide cone and lever clamp wood mechanism with the wooden pawl is grabbed；The cage is led
To 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 leads
It is evenly arranged between large circle and small circle ring to bar, is in cage circular cone columnar structure；The lever clamp wood mechanism is mainly by pressing from both sides
Head, clamp arm, pull ring, pull rod and lever composition；The collet is fixedly mounted on one end of clamp arm, the other end and lever of clamp arm
One end rigid connection, the other end of lever and one end of pull rod are hinged, and the other end of pull rod and one end of pull ring are hinged, pull ring
The other end be equipped with through-hole；The junction of the clamp arm and lever is equipped with circular hole；The large circle passes through circular hole, with clamp arm
It is hinged.
In the present invention, lever clamp wood mechanism is the crossed-symmetrical arrangement using double lever duplex pull rod, can
So that clamp arm and collet is obtained enough chucking powers, improves the reliability of the utility model grasping wood.
The utility model further illustrates that the inner ring of above-described large circle is additionally provided with two struts, and strut
The two sides of large circle Yu clamp arm hinged place are arranged in end.Setting strut can effectively provide support force, avoid lever clamp wood machine
Structure carry out folder carpentery workshop industry when, large circle stress and deform.
The utility model further illustrates that above-described collet is equipped with canine tooth.Canine tooth is set, collet can be allowed fine
Bite wood, avoid wood from being detached from during towing and grab the wooden pawl.
Large circle in the utility model/between small circle ring and guide rod, between collet and clamp arm, between clamp arm and lever
Welding manner can be used to link together, or other rigid connections can also be used.
The operation principle and using method of the utility model:
The wooden pawl of grabbing of the utility model is connect with winch hauling rope, i.e., after the hauling rope of winch being passed through small circle ring
It is fixedly connected on the through-hole of pull ring, the wooden pawl then will be grabbed by cutting area Field Force and be pulled to end of lumber, loosen hauling rope, with double
Hand opens clamp arm, and collet is clamped end of lumber, tenses hauling rope, makes both ends collet by the boosting function of pull rod and lever
It is preliminary to clamp wood.Then starting winch recycles hauling rope, further increases the pulling force of hauling rope, clamps collet further
Wood, until dragging wood is mobile.When wood encounters the barriers such as live standing tree, stump, bushes, earth steps in dragging process
When blocking, by large circle, small circle ring and guide post group at conical head, object can be met with minimum by the small circle ring in cone and connect
Contacting surface product circumvents above-mentioned barrier and is passed through.Wood is dragged to up to after the predetermined area, and winch, which empties shelves, to be loosened
Hauling rope, wood can be unloaded by manually pulling open clamp arm, then the end for grabbing the wooden pawl and taking next wood is clamped, in repetition
That states that step carries out next period grabs the wooden skidding operation.
The advantages of the utility model:
1. the utility model scientific structure design is reasonable, it is simple and practical, winch cable traction logging can be effectively reduced
Support staff in the process can not only save labour, reduce cost of labor, but also can greatly improve cable logging efficiency, will
Important facilitation is played to the popularization and application of winch cable logging technology.
2. the utility model uses double lever duplex pull rod force-increasing mechanism arranged in a crossed manner, obtain clamp arm and collet enough
Chucking power improves and grabs the reliability that the wooden claw clip holds wood.
3. the utility model will grab the wooden pawl Design of Main Structure into cage pyramidal structure, it can not only mitigate own wt and be convenient for
It carries, and is acted on by the guiding of special pyramidal structure and the minimum evacuation for meeting object contact area, make to grab the wooden pawl with automatic
Avoid barrier function.
