Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to an interlocking device for a clutch lever and an accelerator lever of a winch in a transport vehicle mainly used for shipping lumber or the like.

(B) Conventional Technology Conventionally, such transport vehicles have usually been equipped with a winch in order to facilitate the collection and loading of their cargo such as wood.

By the way, these winches require a considerable amount of space to install, so normally,
It cannot be installed in the same location as the engine or control parts.
Therefore, they were distributed and installed at appropriate locations, and each operating member was also provided separately.

(c) Problems to be solved by the invention Therefore, when using a winch, one usually gets out of the vehicle, goes to the place where it is installed, and operates it there.

Therefore, the installation location of this winch and the accelerator lever (usually
(installed in the control section) are located far apart,
In some cases, you may have to travel between both locations.

This is because winches are used at relatively low engine speeds (usually 1000~
1500 rpm), while the engine is used at almost full speed when driving.

This means that when you try to use the winch immediately after driving at full speed, unless you have released the accelerator lever (which is the case in most cases),
This is because you have to return to the original location and perform the operation again.

In particular, in order to be able to load long objects, the platform frame is divided into left and right sides, and one side is made into a flat loading area with no obstacles in front or behind.
In the case of a transport vehicle that has all the equipment gathered on the other side, a winch is mounted on the front due to weight distribution.
Because the engine and control members (accelerator levers, etc.) were located at the rear, it was necessary to travel a very long distance.

(d) Means for solving the problems In order to solve these problems, the present invention takes the following measures.

That is, in a transport vehicle in which a winch, an engine, and an accelerator lever for operation are arranged in this order, the clutch lever for turning on and off the power of the winch and the accelerator lever are made to correspond to their on/off positions and low and high positions, In addition, a regulator handle of the engine with the high-speed side facing the accelerator lever is inserted in the middle and connected with a connecting cable, and a cable that extends and contracts into the connecting cable connecting the regulator handle and the accelerator lever. It is characterized by having a body interposed.

(e) Effect As a result, even if the accelerator lever is located on the high speed side, if the winch clutch lever is operated to the on position, the engine regulator handle will be moved to the low speed side by the connecting cable. At the same time, since the connecting cable between the regulator handle and the accelerator lever is equipped with a telescoping body, the telescoping body expands at this time, lowering the engine speed without changing the position of the accelerator lever. It is possible.

(F) Embodiment Hereinafter, a case where an embodiment of the present invention is applied to the above-mentioned transport vehicle for long objects will be explained with reference to the drawings. Figure 2 is a side view of a transport vehicle to which this invention is applied;
4 are a side view and a front view of the transport vehicle.

First, regarding the transport vehicle, as shown in FIGS. 3 and 4, this transport vehicle is equipped with a partition plate (tilt) 2 in the front and back direction on the loading platform frame 1, which is a horizontal plate. This partitions the loading platform frame 1 into left and right sides. and,
One side (for example, the left side in the direction of travel) is a flat cargo loading area 3 that is free from obstacles in the front, rear, and sideways (left side), and the other side (also the right side) is an equipment loading area 4. It is. Note that a traveling section 8 having a structure in which a crawler 7 is wound between a driving wheel 5 and a driven wheel 6 is suspended below the platform frame 1.

The equipment loading section 4 is equipped with a winch 9 at the front and an engine 1 at the rear.
0 and a control member 11 consisting of various control levers and the like. Furthermore, engine 10
Nearby, a transmission case 12 with a lower output shaft connected to the drive wheel 5 is attached to the chassis frame 1.
Install it diagonally above and below.

As for the winch 9, it has a drum 13 and an auxiliary drum 14 at the forefront of the equipment mounting section 4.
A clutch lever 16 for controlling power on/off to the winch 9 is arranged behind it, and also controls the rotational speed of each drum 13, 14. A shift lever 17, a clutch lever 18, and a brake lever 19 are provided in an operating section 20. At this time, the operating member 11 is brought to the rear of the equipment loading section 4, and there is no seat for the operator to sit on (therefore, this transport vehicle is a walking type), thereby making the vehicle as easy as possible. , the engine 10 is placed at the rear.

On the other hand, a winch pole 21 is erected from the equipment mounting section 4 near the partition plate 2 near the operation section 20, and a jib 22 is extended from the upper end of this winch pole 21 in a left and right T shape, and a pulley 23 is suspended from this. Then, the wire 2 unwound from the drum part 15
4.

Further, a guard device 26 is installed between the winch pole 21 and the machine frame 25 of the winch 9, etc. to protect the operator standing in front of the operating section 20. That is, a grid-shaped guard 27 is diagonally hung between the winch pole 21 and the machine frame 25 to cover the operating section 20 with a constant width.

In addition, side poles 28 are appropriately installed on the platform frame 1 at the side ends of the cargo loading section 3 to prevent the cargo from falling, and the winch poles 21 are prevented from falling due to the tensile force of the wires 24. At the opposite position, a reinforcing cable 29 is stretched between the partition plate 2 and the like.

By the way, in the present invention, in the transport vehicle having the above configuration, first, as shown in FIGS. 1 and 2, the clutch lever 16 of the winch 9 and the accelerator lever 30 of the control member 11 are connected. , by matching each on/off position and low/high position,
and a regulator handle 3 of the engine 10 with the high-speed side facing the accelerator lever 30 side in the middle.
1 is inserted and connected with a semi-rigid operating cable 32 such as a wire made of a combination of an outer and an inner wire.

Next, an elastic body 33 such as a spring is interposed between the regulator handle 31 of the connecting cable 32 and the accelerator lever 30.

In this case, since the operating section 20 consisting of the clutch lever 18 of the winch 9 and the brake lever 19 is present between the clutch lever 16 and the regulator handle 31, the connecting cable 32 should be placed in a place where it will not get in the way. It is necessary to pass through the operating section 20, and generally the operating section 20 allows the operating section 20 to pass through the operating section 20 below. Further, the portion where these connecting cables 32 are linked to the regulator handle 31 is connected to the engine 1.
0 side, this also needs to be covered with a suitable cover 34.

(G) Effects of the Invention As described above, the present invention provides a transport vehicle having the above-mentioned configuration, in which the clutch lever 16 of the winch 9 and the accelerator lever 30 are made to correspond to their respective on/off positions and low and high positions, and are arranged in the middle. The regulator handle 31 of the engine 10 with its high-speed side facing the accelerator lever 30 side is inserted and connected with a connecting cable 32, and an elastic body 33 is inserted into the connecting cable 32 between the regulator handle 31 and the accelerator lever 30. Even if the accelerator lever 30
Even if the clutch lever 16 of the winch 9 remains in the high-speed position, if the clutch lever 16 of the winch 9 is operated to the engaged position, the two 30, 16 are connected by the connecting cable 32, and the accelerator lever 30 and the regulator are connected. Since the elastic body 33 is interposed in the connecting cable 32 connecting the handle 31, only the regulator handle 31 can be positioned on the low speed side.

Therefore, the trouble of having to go to the place where the accelerator lever 30 is installed and operate it to the low speed side is not only eliminated, but also the drum part 15 of the winch 9 suddenly starts at high speed. This means that winch work is easy and safe.

Furthermore, when the clutch lever 16 is returned to the disengaged position, the regulator handle 31 is also returned to the high speed side, so from this point of view as well, there is no need to operate the accelerator lever 30 again.
