Description

[Detailed Description of the Invention] This invention relates to a winch control device for a transport vehicle equipped with a winch.

A simple type of transport vehicle equipped with a winch is often used for cutting and transporting timber in forests, but such transport vehicles require frequent repeated operation of the vehicle body and winch operation. However, because the ground conditions in forests are often poor, it requires considerable skill to perform both of the above operations properly.

On the other hand, the loading platform needs to be as wide as possible, and the partition that separates the loading platform from the cabin needs to be moved as far forward as possible. Therefore, there is not enough space to install levers for controlling the winch behind the seat, and even if they were installed, it would be undesirable in such a place because the driver's body could hit them and cause them to operate unexpectedly. .

Therefore, this invention solves this problem by arranging the levers for travel control and the levers for winch control at effective positions from the seat while taking these conditions into consideration.

Hereinafter, specific embodiments of this invention will be described with reference to the drawings.

Figure 1 is a side view of the transport vehicle, Figure 2 is a plan view, Figure 3 is a plan view of the main parts around the seat, Figure 4 is a side view showing the winch control system, and Figure 5 is a plan view of the main parts. However, the transport vehicle has a loading platform 2 built on top of a crawler-type traveling device 1, this loading platform 2 is partitioned by a partition 3, and a cabin 4 is arranged in the front.
A winch 5 is installed in the middle of the traveling device 1 below the loading platform 2.
It is equipped with.

The main operating tools in the cabin 4 that control travel control are two clutch levers 6, 6' and left and right brake pedals 7, 7' (these are referred to as levers for travel control). In other words, although the details will be omitted, this transmission is a side clutch/brake type used in combine harvesters, etc., and separate clutch levers 6, 6' are used to turn on/off the power to the left and right axles 8, 8' and apply braking. brake pedal 7,
7'. The driver performs these operations while sitting on a seat 9 provided on one side of the cabin 4, and the seat 9 is rotated along its vertical axis 10.
It is structured so that it can be rotated around.

On the other hand, the winch 5 is controlled by the clutch lever 1.
1, a brake lever 12 (these are referred to as winch operating levers), and a clutch pedal 1 that controls power transmission from the transmission to the winch 5.
It will be held in 3rd place. That is, since these are already known, the details will be omitted, but power is transmitted by pressing the cone formed on the drum 14 of the winch 5 against the conical plate formed on the transmission gear, and the surroundings of the drum 14 are Braking is achieved by tightening the brake band 15 wrapped around the vehicle. Note that the operating tool 16 for operating the cone is transmitted to the clutch lever 11 via the rod 17, but in this invention, the push/pull operation of the clutch lever 11 is converted into a movement in the left-right direction of the vehicle body. Similarly, the brake band 15 is also transmitted to the brake lever 12 via the rod 18, but this is also done by movement of the vehicle body in the left-right direction.

Next, power is transmitted from the engine to the gearbox 19 of the transmission and winch 5. First, the power is transmitted from the engine's output pulley 20 to the transmission's input pulley 22 via a belt 21, and then to the output pulley 23 provided coaxially with this input pulley 22. Similarly, the belt 24 transmits the information to the input pulley 25 of the gear box 19 of the winch 5. When the brake pedals 7, 7' mentioned above are depressed, the tension roller 26 which relaxes the belt 21 is actuated, and the clutch pedal 13 is depressed. When pushed in, the tension roller 27, which relaxes the belt 24, is actuated.

By the way, this invention, in addition to the above-mentioned configuration, installs the clutch lever 11 for winch operation and the brake lever 12 immediately in front of the partition 3 and on the side of the seat 9, while the center of rotation of the seat 9 is The vertical axis 10 is approximately the distance to the clutch levers 6, 6' when the seat 9 is facing the front, and the distance to the clutch lever 11 when the seat 9 is rotated to face the clutch lever 11 etc. The positions are set so that they are the same.

As a result, in order to drive and control the vehicle, seats 9
To operate the winch 5, move the seat 9 to the clutch lever 1 for controlling the winch.
If the winch 5 is rotated diagonally backward toward the 1st class, the winch 5 can be operated on the spot.

Since this invention is as described above, by rotating the seat 9, the driver can perform travel control and winch control simultaneously on the spot. Note that when the driver operates the winch, he or she faces diagonally backward; however, winch work is performed using winch 5.
Since the wire 28 unwound from the pulley 29 is not only stretched backwards by the pulley 29, but also stretched forward (so-called front pulling), even such cases can be handled, and with this posture. The clutch pedal 13, which cannot be installed along the line between the clutch lever 11 and the seat 9 due to its structure, can be depressed.

Next, the vertical axis 10 of the seat 9 is determined by the distance between the seat 9 and the clutch levers 6, 6' and the clutch lever 11.
By setting the distances to the brake levers 12 to be approximately the same, the distance that the arm or the like should be extended is the same no matter which one is operated, making it easier to operate.
Furthermore, this means that the space for placing the engine, etc. on the side of the seat 9 can be sufficiently extended to the side of the seat 9.

In addition, clutch lever 11, brake lever 1
By converting the push/pull operation in step 2 into a movement in the left-right direction of the vehicle body, that is, a movement along the partition body 3,
Since the distance between these levers 11, 12 and the partition body 3 only needs to be the minimum, there is an advantage that the partition body 3 can be brought forward as much as possible to make the loading platform 2 wider.
