Description

Technical Field

[0001] The present invention relates to a logging equipment, and particularly to an overhead logging equipment for collecting trees felled in mountains.

Background Art

However, in the case of a hydraulic grapple, cost increase and weight are problems. On the other hand, a wire-type hook has been developed (Patent Document 1), but it is difficult to use in mountainous areas, which is a problem.

Embodiments for Carrying Out the Invention

[0011] Hereinafter, the overhead logging device 1000 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 17. In all the following drawings, for ease of understanding, the dimensions, ratios, etc. of each component are shown differently as appropriate.

[0012] Figure 1 is a schematic front view of a cable-type logging device 1000 according to an embodiment of the present invention. As shown in Figure 1, the cable-type logging device 1000 consists of a mobile unit that moves along a wire cable and a logging machine 1. The logging machine 1 is broadly composed of a clamp unit that grasps felled trees and a relay unit that relays between the clamp unit and the mobile unit. The mobile unit in this embodiment is an existing device shown in Figure 1, but it may also be an existing self-propelled or fixed crane, or a flying device such as a helicopter or drone.

[0013] Figure 2 is a schematic front view showing the state in which the logging machine 1 is gripping a log 10. The intermediate section has a winch section 200 containing a winch (not shown), a rotation control unit 240 that controls the rotation of the clamp section, and a connecting section 301 that connects the winch and the clamp section. The winch is configured to be remotely operated by remote control. Wire connection sections 412 and 413 are provided at both lower ends of the winch section 200, and wires 420 and 421 are provided at wire connection sections 410 and 411 provided at the upper ends of the claws 401 and 402 of the clamp section, respectively. In addition, the wire wound on the winch is connected to the center of the connecting section 301, and wires 310 and 311 are provided at wire connection sections provided from both ends of the connecting section 301 approximately midway between the claws of the clamp section (below the rotation axis 430). In this way, the logging machine 1 closes the claws 401 and 402 of the clamp section by the weight of the log 10. When the timber 10 is moved to the desired location and lands on the ground, winding up the winch causes the claws 401 and 402 to be lifted upward around the rotating shaft 430, and the clamp section opens (see Figure 5). In this way, when the winch of the logging machine 1 is wound up, the claws 401 and 402 are lifted upward around the rotating shaft 430, and the clamp opens. At the same time, the rotation control unit 240 controls the rotation horizontally, allowing it to rotate to an angle that can grasp trees that have fallen in various directions. Lowering the winch wire closes the claws 401 and 402 of the clamp section. Furthermore, by providing a winch in the intermediate section that controls the opening and closing operation of the clamp section, it becomes possible to open and close the clamp section remotely, improving the efficiency and safety of the work.

[0014] The horizontal rotation control mechanism of the clamp section of the logging machine 1 will be explained using Figures 3 and 9 to 11. The horizontal rotation control unit 240 of the logging machine 1 is located directly below the center of the winch 200. The horizontal rotation control unit 240 is formed of two cylinders (see the cross-sectional view in Figure 11). The two cylinders of the horizontal rotation control unit 240 are connected via cam connecting parts 251 and 252. The inner cylinder is configured to slide vertically, and the inner cylinder rotates as the cam connecting parts 251 and 252 move along two guide grooves 241 provided in the outer cylinder. A roughly bowl-shaped opening is provided at the lower end of the inner cylinder. The central part of the connecting part 301 fits into this opening. When the winch is wound up, the central part of the connection part 301 moves upward, causing the inner cylinder of the rotation control unit 240 to move upward. As the cylinder rotates, the connection part 301 rotates in conjunction with this rotation, and the clamp part rotates horizontally in conjunction with the rotation of the connection part 301.

[0015] Figure 4 shows the clamp in the closed position. The rotation of the claw 402 is controlled by a projection 440 provided on the surface of the claw 401. The projection 440 restricts the clockwise rotation of the claw 402.

[0016] Figure 5 shows the clamp in the open position. The rotation of the jaw 402 is controlled by a projection 441 provided on the surface of the jaw 401. The projection 441 restricts the counterclockwise rotation of the jaw 402.

[0017] By providing these protrusions 440 and 441, the opening and closing state of the clamp is restricted.

[0018] The logging device 1000 according to this embodiment provides the following effects. (a) Cost reduction can be achieved by using an electric winch. (i) The opening and closing of the clamp section is performed by a winch, allowing for remote operation, which reduces the amount of manual labor required and enables safe timber harvesting. (c) Because the winch moves together with the clamp, the wire can be shortened. As a result, the winch can be made smaller, which reduces the manufacturing costs of the wire and the winch. In addition, malfunctions during wire winding are less likely to occur, improving the responsiveness and reliability of the opening and closing operation of the clamp. (e) The winch's hoisting control allows for horizontal rotation control of the clamp section, enabling efficient gripping of felled trees. (O) The claws close due to the weight of the wood being gripped, so even if the power supply is lost, the gripped wood will not fall, making it safe.

[0019] The logging machine 2 used in the logging apparatus 1000 of this embodiment will be explained with reference to Figures 12 to 17. Note that components identical to those of logging machine 1 may be given the same reference numerals, and their explanation may be omitted.

[0020] As shown in Figures 12 to 17, the logging machine 2 is equipped with pulleys 410 and 411 at the upper ends of the claws 401 and 402 of the clamp section, and is connected to the winch section 200 by a wire 420. Furthermore, by lifting the intermediate section, the claws 401 and 402 of the clamp section are closed more firmly by the weight of the timber 10 and the wire using the pulleys. By lifting the intermediate section and moving the existing device that moves the overhead line, the timber can be easily released by winding up the winch at the unloading site. In this embodiment, the logging machine 2, by providing pulleys 410 and 411, has the effect of allowing the opening and closing operation of the claws 401 and 402 of the clamp section to be performed smoothly and gripping more strongly.

[0021] The embodiments described above are preferred examples of the present invention and are subject to various technically preferred limitations; however, the scope of the present invention is not unduly limited by the above description. Furthermore, not all of the configurations described in the embodiments described above are essential components of the present invention. Moreover, the configurations described in the embodiments described above may be added to or combined with each other. [Industrial applicability]

[0022] The present invention is widely applicable to logging equipment, and in particular to cable-type logging equipment used to collect timber felled in the mountains. [Explanation of Symbols]
