Description
Technical field
The invention belongs to forest zone cable traction logging technical field, and in particular to the wooden pawl is grabbed in a kind of mountainous region logging.
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 solve existing abrupt slope mountainous region high lead yarding to tie the wooden time-consuming and laborious, wood easily by barrier
The problems such as blocking provides a kind of light, simple, cheap, high-efficient, good reliability, the mountainous region logging that can avoid barrier is grabbed
The wooden pawl.The use for grabbing the wooden pawl of the invention is conducive to winch cable logging technology and answers in the popularization in southern abrupt slope mountainous region forest zone
With for reducing personnel labor intensity and production cost, raising forexry mechanization level and logging efficiency have great importance.
To achieve the goals above, the invention adopts the following technical scheme:
The wooden pawl is grabbed in a kind of mountainous region logging, is mainly made of conical ring, pawl leaf, central pull ring and pull rod；One end of the pawl leaf with
Conical ring is hinged, and the medial surface of the other end is equipped with canine tooth；The pawl leaf is by connection blade triangular in shape and trapezoidal grabs wood
Blade composition, and connecting blade and grabbing the interconnecting piece of the wooden blade is in that bent outward is curved；One end of the pull rod and pawl leaf
The medial surface of connection blade and the interconnecting piece for grabbing the wooden blade is hinged, and the other end is hinged with central pull ring.
The present invention further illustrates, there are three above-described pawl leaf is set, and is uniformly distributed and is hinged on conical ring.
The present invention further illustrates that the center of circle of above-described conical ring and the center of circle of central pull ring are in same horizontal line
On.Conical ring, central pull ring are sequentially passed through convenient for the end of hauling rope, and when carrying out skidding operation, central pull ring can be made
The pawl leaf uniform force of surrounding, provides relatively reliable bite force.
The present invention further illustrates that above-described pawl leaf sets fanged end face as arc surface.The circle of canine tooth is set
Cambered surface can more preferably match wood, preferably be engaged wood, avoid wood from being detached from during towing and grab the wooden pawl.
The working principle of the invention and application method:
First the hauling rope for grabbing the wooden pawl and winch of the invention is connected, i.e., the end of hauling rope is sequentially passed through into conical ring, center
After pull ring, hauling rope end is knotted or one annulus of bind, central pull ring is blocked；Then wood will be grabbed by cutting area Field Force
Pawl is pulled to end of lumber, loosens hauling rope, breaks three pawl leaves into two with one's hands with hand, and pawl leaf is allowed to clamp end of lumber, tenses hauling rope, makes pawl
Leaf tentatively clamps wood, then starts winch, and the pulling force for increasing hauling rope clamps pawl leaf further, can drag wood.
Wood reach the predetermined area after, loosen hauling rope, wood can be unloaded by moving central pull ring with hand push, then will grab the wooden pawl take it is next
The end of root wood, carry out next period grabs carpentery workshop industry.
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 draws three pawl leaves using a pull ring, keep power symmetrical, mechanical movement more reliable performance.
3. the present invention will grab the wooden pawl Design of Main Structure into three valve pyramidal structures, not only make to grab the wooden pawl with obstacle evacuation function
Can, and weight can also be mitigated, it is easy to carry.
