Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outrigger attached to a vehicle body such as a launcher or radar device,
Particularly, the present invention relates to an outrigger that is effective for stabilizing the vehicle body when used on soft ground.

[0002]

2. Description of the Related Art Conventionally, in launchers and radar devices, outriggers have been used for supporting the vehicle body side due to the impact of launching a missile and the rotational movement of a radar antenna.
This allows the gate-shaped frame to expand and contract in the width direction of the vehicle body, but also keeps the vehicle body stable by abutting the legs against the ground contact surface, ensuring stability of the vehicle body during missile launch and radar antenna rotation operation. It is a thing. The conventional outrigger has a telescopic structure and is expanded and contracted by hydraulic pressure, and is used with the legs directly abutting the ground. As a result, the vehicle body and the load on the vehicle body are supported, and the impact and the rotation moment generated by the launch of the missile and the rotation of the radar antenna are supported by the ground reaction force.

FIG. 15 shows a conventional outrigger. In the figure, an outrigger 1 is arranged at the front, rear, left and right positions of a vehicle (not shown) and is capable of expanding and contracting in the horizontal direction, and a girder portion 2 arranged at the end of the outrigger 1 in the vertical direction. It has leg portions 3 that can be expanded and contracted. Therefore, the legs are arranged at the four corners of the vehicle. A ground plate 4 that directly contacts the ground is provided at the lower end of the leg so as to receive a ground reaction force when the outrigger is used.

[0004]

In the conventional outrigger, since the size of the grounding plate is fixed, the grounding pressure to the ground is too large and the frictional force is small on the soft ground or slippery ground. There is a problem that the vehicle body sinks or the vehicle body shifts due to the impact of launching, the rotation operation of the radar antenna, etc. For this reason, in the conventional outrigger, it is difficult to increase the size of the grounding plate to reduce the grounding pressure due to the limitation of the vehicle body width due to the Road Traffic Law, etc., so that a large plate-shaped plate is manually laid under the grounding plate, There was a problem in operability because it was necessary to hammer the pile into the ground plate with a hammer or the like to fix it.

The present invention focuses on the above conventional problems,
It provides an outrigger that guarantees safe and stable operation of the launcher and radar device by automatically increasing the area of the grounding plate or automatically striking the pile on soft or slippery ground. is there.
