Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead wire carrying device and an overhead wire routing method thereof, for example, related to a cording material of a hole back line or slack pulling line that contributes to carrying a carrier and a main line that contributes to lifting a carried object. Inter-drum interlock control for horsepower regeneration, efficient operation with low loss, easy laying, and optimal use for lumber harvesting in mountain forests To do.

  Conventionally, to collect timber harvested in slopes, valleys, rivers, concave parts, forests where there are obstacles such as tree stocks and rocks, the branches of timber are first used with a tool such as a chain saw. The paper was cut and then gathered in a certain place. At this time, for example, a running skyline method is used as a method of lifting and transporting timber in the air with overhead wires in order to collect timber collected on slopes where the scaffolding is unstable in mountain forests, etc. There is a method for transporting overhead wires (see Patent Document 1).

  That is, by driving a motor or the like, for example, a first and a second set of winch portions provided on a carriage, for example, so as to be rotatable at the same speed, and one end side of the winch portion is wound so that it can be wound and fed out. A base frame portion to which the other end of the hallback line is fixed via a two-line cable of a hallback line and a main line, and a fixed pulley for changing the direction attached to a fixed height such as a standing tree. The main frame frame is rotatably mounted on the upper part of the base frame part, and is movably mounted on the upper overhead line part of the hallback line. A structure comprising a carrier formed by a suspension pulley mounted below the base frame so as to be bound to a hoist line on the other end side of the line.

  In order to transport the wood, first, a desired one end side (root) of the wood or the like whose branches are removed by a tool such as a chain saw is bound to a hoist line at one end of the main line. After that, one end of each of the hall back line and the main line is wound and the first and second winch portions having different rotation directions are driven by a motor or the like to rotate the drum body, respectively. When the line and the main line are fed in the opposite directions at the same speed and lifted, the carrier having the base frame portion to which one end of the hall back line is bound is guided to the upper overhead line portion of the hall back line. Since it moves by receiving the tensile force of the main line, one end (root side) is bound by the (front end) of the hoist line that is wound around the suspension pulley installed in the lower part of this carrier. Wood is transported to a desired place while being lifted in the air along an inclined land or the like, and is collected.

Japanese Examined Patent Publication No. 6-61189

  However, the conventional running skyline method described in Patent Document 1 is a first method for scooping out or feeding out the hallback line and the main line when transporting a transported object such as wood. When the second winch part is driven by a motor or the like and operated, no mutual linking means is provided between the drum bodies of the first and second winch parts by an interlock mechanism. When the desired one end (base) of the timber is tied to one end of the hoist line suspended from the carrier, the anti-braking force associated with the load of the wood as the object to be transported is applied to the hole back line. It must be tied to one end of the hoist line to prevent the carrier from inadvertently running alone by hanging or preventing the wood from descending. In order to apply this anti-braking force to the hallback line, for example, hydraulic brakes, manual brakes, and slipping clutches are used, but the brakes are overheated, the lining wears out, and the life of the parts is reduced. It will be short-lived, and it will cause a great loss of horsepower, and fuel will be lost wastefully.

  In addition, it is difficult to adjust the anti-braking force in actual driving operation, and the carrier is inadvertently lowered or raised too much. For example, when unloading to transport and transport a transported object from the mountain side to the valley side along the slope of a mountainous area, routing the rope to bind the transported object to the hoist line suspended from the carrier However, if the load and the moving speed of the hole back line are not taken into consideration when transporting the transported object, the transported object is likely to fluctuate during transportation, or it may easily shake and become unstable. It will collapse. In addition, in the case of an overload that transports and transports the object to be transported from the valley side to the mountain side along the slope of the mountainous area, the hoist line is suspended from a carrier at a position where the overhead line is high on the valley side. After that, it took a lot of time and labor to draw the hoist line to bind the object to be loaded against one end of the hoist line suspended. And to transport and transport the objects to be transported, the installation height of the overhead line where the carrier is reciprocated, the main line and the hall back line along the slope of the mountain, and the scraping operation However, unless the anti-braking force against the hall-back line was controlled, it could not be transported and transported while considering the object to be transported. In addition, since the operation is performed while applying the anti-braking force to the hole back line as described above, high-speed operation is difficult and efficiency is low.

  Moreover, the main line for transporting and transporting the transporter and the laying work for the hall-back line have taken much time and labor. In addition, as described above, the hydraulic brake, manual brake, and slipping clutch need to be incorporated into the driving mechanism, and the cable tensioning uses a thick cord material that can withstand anti-braking force. Since the drum diameter of the drum body of the winch part 2 is increased, the apparatus itself is increased in size and weight.

  The present invention solves the above-mentioned conventional inconvenience, can be operated with a simple handling operation, can be operated at high speed, and the transporter can be moved without being lowered or raised carelessly. It can be transported at a stable lifting height, and there is little overheating of the brake or wear of the lining, so that the service life of the parts is extended, these devices are not required, and there is no loss of horsepower. Interlock control is used to regenerate horsepower, so there is no wasteful loss of fuel, efficient operation is possible, and laying is easy and reliable, and it is not necessary to use a cord that is thicker than necessary.
