JPH07172765A - Roller frame structure of rope type carrier - Google Patents

Abstract

PURPOSE:To make the position of an engine so as not to be changed inso far as possible in enabling a load-hanging rope alone to be inclined by supporting an interval between a front part lift-supporting drum of a roller frame and a guide roller of a roller frame rotatably with a support shaft attached to a machine body toward the drawing direction of a main rope. CONSTITUTION:A connecting plate 36 is attached to the vicinity of a front end of an arm 20, and a support shaft 38 is attached to a machine body toward the drawing direction of a main rope 10 from the center of this connecting plate 36. In addition, a roller frame 40 is rotatably attached to this support shaft 38, and a front part lift-supporting drum 16 is attached to an upper part of the support shaft 38 of this roller frame 40 and a guide roller 34 to the lower part, respectively. With this constitution, if a winch drum is driven by power of an engine, a load is hung down by a load-hanging rope 32. Simultaneously, if the power is transmitted to a travel drum, the machine body shifts along the main rope as drawing in a running rope 12 toward itself. At this time, the load-hanging rope 32 is drawn sideways, but at that time the roller frame 40 rotates centering on the support shaft 38, whereby it corresponds to this motion, so that a position of the machine body is not changed so much.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope-type carrier for use in cutting out timber, etc., in which a roller frame for attaching a suspension drum for suspending the main body to a main rope and a guide roller for guiding a load rope. It is about structure.

[0002]

2. Description of the Related Art In order to carry wood cut out in forests with poor scaffolding, use a rope-type carrier that moves along a main rope stretched between two points such as trees, Suspend and transport. In this case, the load line is not only extended in the vertical direction but may be extended in the lateral direction in some cases (so-called lateral pulling). If you pull it sideways, the machine body will tilt, and the engine will also tilt accordingly, so there is a risk that the lubrication oil will not rotate properly and may cause seizure.

Therefore, a means for preventing this is required, but in the conventional one, a winch device is provided independently so that it can be tilted separately from the machine body, or a winch is fixed to the machine body and the machine body itself is tilted. There are things that are difficult to do.

[0004]

However, in the former case, the structure is complicated and the cost is high, and
The latter type has a drawback that the range in which horizontal drawing can be performed is narrowed. The present invention solves such a problem. Although the winch device is fixed to the machine body to simplify the structure, the cargo line can be tilted.

[0005]

Under the above problems, according to the present invention, a main rope and a traveling rope are stretched between two points, and a front suspension drum and a rear suspension drum are attached to the main rope. A rope-type transporter that suspends a vehicle and drives the traveling drum around which the traveling rope is wound to move the machine body along the main rope, and also drives the winch drum around which the rope is wound to suspend the cargo. In the above, the front suspension drum and the guide roller for guiding the cargo line are attached to the roller frame in a vertical arrangement, and the space between the front suspension drum of the roller frame and the guide roller is extended in the main body in the extending direction of the main rope. It is characterized in that it is rotatably supported by a support shaft that is attached toward.

[0006]

By taking the above means, even if the roller frame is pulled laterally, the roller frame rotates around the support shaft, the guide roller faces the load direction, and the machine body hardly tilts.
Even if the roller frame is tilted, the posture of the front suspension drum hardly changes, so that the suspension function and the traveling function of the machine body are not hindered.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 5 is an explanatory diagram showing the usage state of the rope-type carrier, but this rope-type carrier is used for the main rope 10 and the traveling rope between two fixed points (for example, strong trees) in a forest or the like. 12 and 12 are laid on top of each other, the main body 10 suspends the body 14, and the traveling rope 12 is manually moved.

FIG. 3 is a side view of the rope-type carrier, and FIG. 4 is a plan view. The front suspension drum 16 and the rear suspension drum 18 are attached to the machine body 14 in a state of extending upward. The body 14 is movably suspended by suspending the suspension drums 16 and 18 on the main ropes 10. Although the rear suspension drum 18 is fixed to the machine body 14, the front suspension drum 16 is provided with an extendable and retractable arm 20 extending horizontally from the machine body 14 and attached to this arm 20.

Further, a traveling drum 26, to which power is transmitted by the engine 22 and the transmission 24, is also attached to the machine body 14, and the traveling rope 12 is wound around the traveling drum 26 two to three times. As a result, when the traveling drum 26 is driven, the machine body 14 can move. A cord drum 28, which is used when the main rope 10 is first tensioned, is provided along with the traveling drum 26. Furthermore, Aircraft 1
4 is also provided with a winch drum 30,
The rope 32 unwound from the winch drum 30 is the arm 2
It is guided by a guide roller 34 attached to the tip of 0 and is extended downward.

FIG. 1 is a partial sectional side view showing the attachment of the front suspension drum 16 and the guide roller 34, and FIG. 2 is a front view of the same. The support shaft 38 is attached from the center of 36 to the front (the extending direction of the main rope 10). The roller frame 40 is rotatably attached to the support shaft 38, and the front suspension drum 16 is provided above the support shaft 38 of the roller frame 40.
The guide rollers 34 are attached below.

At this time, the support shaft 38 is provided with its shaft center slightly raised rearward, and its extension line is directed to the contact point A between the main rope 10 and the rear suspension drum 18. A guide drum 42 for guiding the traveling rope 12 and the like are also attached to the roller frame 40.

As described above, when the winch drum 30 is driven by the power of the engine 22, the load is suspended by the load line 32. At the same time, if the power is transmitted to the traveling drum 26,
The machine body 14 moves along the main rope 10 by handing the traveling rope 12. Although such an operation is controlled by a radio control, its details are omitted here.

By the way, as described above, at this time, the cargo line 32 may be pulled laterally, that is, so-called lateral pulling may be performed. In such a case, the roller frame 40 is rotated around the support shaft 38. The posture of the body 14 does not change so much in response to the movement. In this case, when the extension line of the support shaft 38 is directed to the contact point A between the main rope 10 and the rear suspension drum 18, the rotation of the roller frame 40 becomes smoother.

[0014]

As described above, since the present invention is as described above, the roller frame faces in that direction even when individual drawing is performed, and the attitude of the machine body, that is, the engine does not change so much.
Therefore, seizure of the engine can be prevented. Further, it is possible to expect an effect that no excessive force is applied to each part of the machine body and the wire is not damaged.
