Convenient wood gripper capable of avoiding obstacles

Abstract

The invention discloses a convenient wood gripper capable of avoiding obstacles. The convenient wood gripper mainly consists of a cage-shaped guide cone and a lever wood gripping mechanism, wherein the cage-shaped guide cone mainly consists of a large circular ring, a small circular ring and guide rods; the large circular ring is parallel with the small circular ring; the guide rods are uniformlydistributed between the large circular ring and the small circular ring; the lever wood gripping mechanism mainly consists of a gripping head, a gripping arm, a pull ring, a pull rod and a lever; thegripping head is fixedly arranged at one end of the gripping arm, the other end of the gripping arm is rigidly connected with one end of the lever, the other end of the lever is hinged to one end of the pull rod, and the other end of the pull rod is hinged to one end of the pull ring; a circular hole is formed in the connecting part of the gripping arm and the lever; the large circular ring penetrates through the circular hole, and is hinged to the gripping arm. The convenient wood gripper has the advantages that the number of auxiliary persons in the cable traction and skidding process of a winch machine can be effectively reduced, the labor is saved, the labor cost is reduced, the cable skidding efficiency is greatly improved, and the important promotion function is realized on the popularization and application of the cable skidding technique of the winch machine.

Description

technical field [0001] The invention belongs to the technical field of cable traction skidding in forest areas, and in particular relates to a portable wooden claw that can avoid obstacles. Background technique [0002] The winch cable traction skidding technology has been widely used in the southern steep slope forest area. This skidding technology has played an important role in reducing the labor intensity of workers and improving the production efficiency of wood skidding. For example, the Chinese patent No. CN201410402987X discloses a method for expanding the one-time installation of a cable skidding crane, including the following steps: Step 1, taking the vertical ground projection of the load-carrying cable as the central axis, with a width of 20 meters on both sides of the central axis Set a 20-meter boundary line at the 20-meter boundary line; step 2, look for a standing log or felling root inside the 20-meter boundary line; step 3, set a guide pulley on the standin...

Problems solved by technology

[0003] However, there are still some technical problems that need to be solved urgently in this logging technology: first, when using cable logging technology to log, you must first bind the ends of the wood with a tying rope, and then tie the end of the wood on the winch machine tow rope. The hook hooks the bundled wooden rope to carry out traction and skidding, and the operation is time-consuming and laborious

The second is that in the process of cable traction and skidding, because the end of the wood is completely exposed and the contact area is large, it is often blocked by obstacles in the cutting area such as living trees, felling roots, bushes, and ridges, and cannot be dragged smoothly.

Therefore, it is necessary to send additional personnel to follow the wood all the way to help remove obstacles, which is dangerous and labor-intensive, which greatly affects the efficiency of skidding production.
