Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technology for preventing a vehicle such as a truck, a car, a special transport vehicle, or the like running using tires from moving or running away due to rolling when the vehicle is stopped, and particularly to effectively preventing the vehicle from moving when the vehicle is stopped on a slope. It is a technology to do.
[0002]
[Prior art]
Conventionally, when stopping a vehicle on a slope, the tire brake is operated, but when the slope of the slope is large, when the vehicle loading weight is large, or when the braking force is weak, the braking force is lost and the tire rolls. Or there was a danger of slipping and moving on a slope.
As a method of preventing this movement of the truck 1 of the vehicle, as shown in FIG. 6, a wedge-shaped (triangular) wood piece tire stopper 30 is placed on the downhill side of the front and rear tires 9, 10. If the tire comes off, or if the tire stopper 30 is pushed by the front and rear tires 9 and 10 to move, the effect of preventing the movement is lost, and there is a risk of rolling movement of the vehicle.
In addition, a plurality of tire stoppers 30 are stored in a vehicle, and it takes time and effort to remove, install, and store them.
[0003]

[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The horizontal hydraulic cylinder that advances and retracts the cylinder rod and wedge toward the front wheel tire and the horizontal hydraulic cylinder that advances and retracts toward the rear wheel tire are connected and integrated so as to be in a horizontal line, This is preferable because the horizontal reaction force from the tire can be offset and the load on the mounting strength can be reduced.
In addition, as a configuration in which a horizontal hydraulic cylinder is vertically suspended below the vehicle body, a vertical hydraulic cylinder that moves the cylinder rod up and down is attached to the lower part of the vehicle body, and the horizontal hydraulic cylinder is mounted using the vertical hydraulic cylinder. A structure in which the cylinder casing of the cylinder is moved up and down is simple and preferable.
Further, the lifting means may be a mechanical lifting mechanism that is manually operated without using a cylinder or electric motor.
