Description

[Detailed description of the invention] The present invention relates to a pedal locking device for a work vehicle that is provided with a pedal that can be depressed forward or backward across the stop position, and is designed to allow the pedal lock to be configured and operated easily and reliably. The purpose is to

More specifically, in a work vehicle, it is extremely dangerous if the stop pedal is accidentally operated while the vehicle is moving, or if the travel pedal is accidentally operated while the vehicle is in motion. This invention is intended to fully satisfy such demands.

Next, embodiments of the present invention will be described with reference to illustrative drawings.

As shown in FIG. 1, a swivel platform 5 equipped with a backhoe device 2, a boarding and driving section 3, and a driving section 4, and a dozer device 6 are attached to a wheeled vehicle body 1, and excavation work and dozer work can be selectively performed. The work vehicle is configured to carry out the work.

In the boarding operation section 3, as shown in FIG. 2, an accelerator pedal 8 and a brake pedal 9 for driving are arranged side by side on the right side of the rotating steering wheel 7, and a dozer device 6 is installed on the left side of the steering wheel 7. A pedal 10 that operates the hydraulic cylinder 6a for raising and lowering the
is provided so that it can be stepped forward or reversely across the stop position, and a speed change lever 12 for traveling is provided on the left side of the driver's seat 11. A lever 13 for selecting a mode and an accelerator lever 14 are arranged side by side on the left and right, and a forward/reverse switching lever 15 is attached to the post of the handlebar 7 so as to protrude to the left, and a lever that also functions as a turn signal and a horn is attached to the post of the handle 7. 16 is attached, and two control levers 17a and 17b for the backhoe device 2, which are swingable in two-dimensional directions, are distributed to the left and right with respect to the driver's seat 11.

As shown in FIG. 3, the dozer pedal 10
The member 18 that locks the
The lock device is provided so as to be swingable around an axis P ₂ which is different in direction from P ₁ , preferably approximately at right angles, and can be freely switched between a locking position and an unlocking position. In this position, the plate-like acting portion 18a of the locking member 18 is configured to be close to the tread surface of the pedal 10 across the front and back of the pivot axis _P1 , so that the plate-like acting portion 18a of the locking member 18 can be moved forward or backward from the rest position of the pedal 10. The locking member 18 is constructed so as to be prevented from swinging, and the locking member 18 is constructed so that it can be used as a footrest in the locking position.

The present invention can be applied to various construction vehicles, agricultural vehicles, etc., and the pedals can be operated on any object.

In addition, the operating portion 18a of the pedal lock member 18
Various configuration changes are possible, for example, rod-like or framework-like.

In summary, the present invention provides the pedal locking device for the work vehicle described above, in which the pedal locking member ₁₈ is provided so as to be swingable around an axis _P2 which is different in direction from the swinging axis P1 of the pedal 10. The pedal lock member 18 is characterized in that the operating portion 18a of the pedal lock member 18 is formed so as to come into contact with the pedal 10 in the operating position at positions distributed forward and backward with respect to the swing axis _P1 .

That is, the operating portion 18a, which is made of, for example, a plate-shaped body, a rod-shaped body, etc., and which is configured to come into contact with the pedal 10 at the locking position as described above, is simply aligned with the uniaxial center P _{2 .}
Since it is simply swung around the dozer, the configuration and operation are simple, and the pedal 10, which can be depressed in either direction or reverse, can be reliably locked. We have been able to provide an extremely effective means for preventing various possible dangerous situations on work vehicles.
