うな配慮を必ずしも必要としない。 The loose pivot parts 7 and 8 shown in the figure are positioned above the center of gravity in FIG. In the free state of the cylinder, the telescopic cylinder 4 is always horizontal beam 3
However, when the telescoping cylinder 4 is extended within a range where the ground plate 6 does not touch the ground, the loose pivoting portion of the telescoping cylinder including the ground plate is located above the center of gravity of the telescoping cylinder. You can also do it like this. The upper end of the illustrated pin hole 7 is formed into a V-shaped hole wall 7a as shown in FIG. However, if a roller is attached coaxially to the tip of the pin 8 and the roller loosely fits into the pin hole, such consideration is not necessarily required.

０，１１の間には僅少の隙間が形成されている。 According to the above configuration, the horizontal beam 3 is connected to the horizontal base tube 2.
While the horizontal beam is extended to the side to activate the outrigger and the telescopic cylinder 4 is extended from the retracted state to the point just before the ground plate 6 touches the ground, the telescopic cylinder is moved by the loose pivot portion 7, 8, the engagement plate 1 is held vertically as shown in FIG.
A slight gap is formed between 0 and 11.

シリンダ４が傾動するため、該水平ビームと伸縮
シリンダ間の連動は円滑に行われる。 When the telescopic cylinder 4 is further extended in this state, the ground plate 6 first reaches the ground surface as shown by the solid line in FIG.
The male and female arcuate engaging surfaces 10a and 11a engage with each other while compressing the elastic member 12, and the pin hole 7 rises relative to the pin 8 as shown by the chain line in FIG. A gap is formed between the two to allow the telescopic cylinder 4 to tilt in conjunction with the deflection of the horizontal beam 3. For this reason, the subsequent extension of the telescopic cylinder 4 pushes up the tip of the horizontal beam 3 through the female and male circular arc-shaped engagement surfaces, lifting the truck crane from the ground.
As it bends as shown in FIG.
The telescopic cylinder tilts as shown by the chain line 4' with 0 as the center while slipping between 0 and 4'. In this case, as the horizontal beam is deflected, the telescopic cylinder 4 tilts in the direction of the frictional force exerted by the female arc-shaped engagement surface 10a on the male arc-shaped engagement surface 11a, so that the interlock between the horizontal beam and the telescopic cylinder can be smoothly performed. be exposed.

ド５に曲げ力が作用しないようにするためであ
る。 The reason why the centers of the male and female circular arc-shaped engagement surfaces are aligned with the rotation center 0 of the ball joint 9 during outrigger operation is so that the line of action of the load acting on the male circular arc-shaped engagement surface 11a all passes through the center 0. This is to prevent bending force from acting on the piston rod 5.

対的回動が作用してもピン８にピン孔７が係合し
て該両者の相対的回動を阻止するから、安全上の
問題はない。 When the truck crane is lifted and supported from the ground G and the outriggers are in operation, the rotation of the telescopic cylinder 4 with respect to the horizontal beam 3 is prevented by the friction between the male and female arcuate engagement surfaces. There is almost no possibility that the telescopic cylinder will rotate relative to each other, and even if a relative rotation that exceeds the frictional force is applied, the pin hole 7 will engage the pin 8 and the relative rotation between the two will be prevented. There is no safety issue since it will be prevented.
以上一実施例について説明したが、水平ビーム
軸線と伸縮シリンダ軸線を正確に交叉させたい場
合は雌雄の円弧状係合面を球面の一部とすること
ができ、こうすれば水平ビームに直角に作用する
水平方向の力に対する抵抗性も増大し得る。 Although one embodiment has been described above, if it is desired that the horizontal beam axis and the telescopic cylinder axis intersect accurately, the male and female arcuate engaging surfaces can be made part of a spherical surface, and in this way, they can be aligned at right angles to the horizontal beam. Resistance to applied horizontal forces may also be increased.

る効果がある。 According to the present invention, when the ground plate is not in contact with the ground, the loose pivot portion functions to support the telescopic cylinder by the horizontal beam, position the center of the telescopic cylinder, maintain the vertical posture, and engage the male and female in an arcuate manner. When the outriggers, whose surface slides to touch the ground, are activated, the loose pivoting part does not interfere with the tilting of the telescopic cylinder that is linked to the deflection of the horizontal beam, so even if the horizontal beam is deflected greatly when the outriggers are activated, the male and female Due to the contact pressure between the arcuate engagement surfaces, almost no bending force is applied to the piston rod, which has the effect of reducing the weight of the outrigger without causing oil leakage or shortening the life of the telescopic cylinder. .
