Description

{Structure for Open Carrier rack of Lentinula timbers}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rack structure for transporting and transporting logs, which can be opened and closed, and more particularly, to a rack structure for transporting and transporting logs.

Generally, a log transport vehicle uses a plurality of splints and ropes when loading logs in the loading section. That is, after the splints are vertically arranged parallel to the loading portion of the vehicle, the lower ends of the splints are connected to each other by using a rope, and the first logs are formed by mounting the logs on the ropes between the splints, Using the rope on the floor, the vertically installed splints are tied together again.

If the split is again bundled by the rope as described above, the second bundle of wood is loaded on the bundled rope, the bundle is bundled again on the second bundle of wood using the rope, and the third bundle of wood is loaded on the rope , The rope is bundled with the rope again, and then the fourth layer is placed on the rope in such a manner that the roots and the roots are alternately stacked to secure the roots. When the roots are stacked together, ropes are spliced on the roots As a bundle, secure the rope up to the best log floor.

When the loading of the log is completed in the loading part of the log transportation vehicle, the log transporting vehicle moves to the loading area of the log, and when it arrives at the loading area, the loading operation starts. After a predetermined position of the splint is horizontally cut at the lower end of the uppermost wood layer, the uppermost wood layer is pushed out toward the cut splint, and after cutting the predetermined position of the splint corresponding to the lower end of the lower wood layer, Are unloaded by pushing them toward the severed splint, and the lower layer is sequentially unloaded in this manner.

However, the above-mentioned conventional timber loading and unloading operations require a large number of operators, and it takes much time for loading and unloading operations, and splints and ropes used for loading can not be used again, Since the purchase of the rope is expensive, the cost of labor and materials is expensive, but the workability is significantly lowered. In addition, since large-scale logging is performed in the mountainous region in order to secure a large number of splints required for loading the wood, There is a problem in that a splint is often broken when a timber transportation vehicle is moved, thereby causing a large traffic accident.

Therefore, as a conventional technique, logarithmic loading and unloading devices for log transport vehicles of Registration Utility Model No. 0314246 (registered on May 5, 2003) have been proposed.

As shown in Figs. 1 and 2, the log loading and unloading apparatus 10 for a log conveying vehicle has a structure in which the lengthwise direction of the loading section is set on the loading section of the log conveying vehicle 30 The assembled body 20 of the side support 22 is assembled oppositely to each of the actuating parts 12 and 13 of the plurality of pedestals 11 fixedly spaced apart from each other at predetermined intervals, 19 are pivoted upward and then the release lever 17a of the first operating rod 17 which is provided opposite to both sides of the pedestal 11 in opposite directions is pivoted and rotated downward so as to engage the engaging recesses 12e Each of the first and second actuating rods 17 and 17 has an engaging projection 17b which engages with the engaging projections 17a and 17b of the first actuating rod 17, In order to prevent the end portion on the side of the portion 17b from rising upward, When the rod 17 is pulled out, the second actuating rod 18 is also interlocked and pulled in the longitudinal direction so that the actuating plate 16 is rotated clockwise (hereinafter referred to as the right actuating part 130) The bottom surface of the fastening groove 15a of the fastening shaft 15 abuts against the upper surface 20b of the fastening protrusion 20a of the assembly 20 so that the assembly 20 is rotated in the clockwise direction, 12) 13, respectively.

When the stacking of the log 31 is completed by using the forklift in the assembled state as described above, the connecting means 21 is fastened to the upper end of the side support 22, Is completed.

The log transport vehicle 30 having been loaded with the log 31 as described above moves to the unloading place and unloads the log 31. The log of the log 31 is first determined as to which of the logs is unloaded The stopper portion 17b is rotated in the upward direction by holding the release lever 17a of the first operation rod 17 after the stopper 19 is rotated upward in the direction opposite to the loading direction of the rear wood 31, The first and second operation rods 17 and 18 are pushed together so that the operation plate 16 is rotated in the counterclockwise direction by pushing the release lever 17b after the first and second operation rods 17 and 18 are detached from the latch recesses 12e and 13e, So that the coupling shaft 15 is also rotated in the counterclockwise direction so that the bottom surface of the coupling groove 15a is separated from the upper surface 20b of the coupling protrusion 20a of the assembly 20, The assembled body 20 in which the stationary state is released is dismounted by the load of the loaded log 31, The assembly 20 is removed from the operating portion 13 by the load of the log 31 and the lower end of the side support 22 is pushed outwardly by the detachment of the assembly 20. [ The lumber 31 loaded on the side support 22 is pushed out to the side supported by the load by the load and is unloaded and the side support 22 pushed outward is connected to the connecting means 21 The assembly 20 is placed on the upper part of the log 31 unloaded without being laid under the unloaded log 31 so that the assembly 20 is again assembled to the operation part 13 by the above- So that the unloading operation can be completed simply and quickly.

However, the conventional timber carrier and loading and unloading device for the timber carrier constructed as described above are connected by several parts to load the timber 31 in the timber carrier 30, The wood logs 31 are pushed down toward the outer side support 22 by their own weight and are lifted and dropped down to the ground so that the damage of the logs is inevitable and many There is a problem that the manufacturing cost is high owing to the coupling structure between the parts and easily broken and broken by the collision of the logs during use.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rack structure for transporting, transporting, and unloading and storing a log (timber) to be opened and closed.
