【0014】
前記支持アーム13は、基端を前記回動体12に連結固定されると共に前端に接地板13aが設けられ、台車4の外方へ向けて八の字状に張り出し自在で、且つ、それぞれの先端に設けられた接地板11aが接地自在な形状に形成されている。
【0015】
つぎに、接地高さ自動調整機構14の構成について説明する。
【0016】
この接地高さ自働調整機構12は、図4〜図7に示すように、前記取付ブラケット13と前記回動体12との間に配設されている。
【0017】
回動体12には、支持アーム13を収納位置に固定する収納位置決めテーパー孔15と、支持アーム13の接地板13aの地面への接地高さの位置を自動的に調整して台車4の平行出しを行う調整位置決めテーパー孔16とが設けられ、取付ブラケット11の両側板11b,11c間に支持軸17を介して回動自在に軸支されている。

[0026]
If the ground on which the cart 4 is to be placed has irregularities, the ground plate 13a of one support arm 13 is grounded at the position of S1 (recess on the ground) shown in FIGS. The grounding plate 13a is grounded at the position of S2 (convex portion of the ground) shown in FIGS. 5 and 6, and the position of the grounding height of the grounding plate 13a of the left and right support arms 13 on the ground is automatically adjusted. The mechanism 14 automatically adjusts and the carriage 4 is parallelized. Thereby, the chassis 4 is set on the ground in a stable state.
[0027]
As shown in FIG. 7A, the automatic ground contact height adjusting mechanism 14 in this state has an adjustment positioning taper in which the taper locking body 18 of the locking device 19 is formed on the rotating body 12 as shown in FIG. The other support arm 13 is completely inserted into the hole 16, and the other support arm 13 is moved upward via the support shaft 17 by the upward movement of the support arm 13 as shown in FIG. The taper locking member 18 of the locking device 19 is supported by a taper portion 24 in the lower half of the adjustment positioning taper hole 16 formed in the rotating body 12.
[0028]
When the unevenness of the ground on which the carriage 4 is installed is further large, the ground plate 13a of one support arm 13 is grounded at the position of S1 (recess on the ground) shown in FIGS. The ground plate 13a of the support arm 13 is grounded at the position of S3 (convex portion of the ground) shown in FIGS. 5 and 6, and the position of the ground plate 13a of the left and right support arms 13 at the ground height is determined by the ground height. Then, the automatic adjustment mechanism 14 automatically adjusts and the carriage 4 is parallelized. Thereby, the cart 4 is set on the ground in a stable state.
[0029]
As shown in FIG. 7A, the automatic ground contact height adjusting mechanism 14 in this state has an adjustment positioning taper in which the taper locking body 18 of the locking device 19 is formed on the rotating body 12 as shown in FIG. The other support arm 13 is completely inserted into the hole 16, and the other support arm 13 moves the support shaft 17 by the upward movement of the support arm 13 as shown in FIG. The taper locking member 18 of the locking device 19 is further rotated upward through the lower portion of the adjusting positioning taper hole 16 formed in the rotating body 12 and is supported by the taper portion 24 of the outer half.
[0030]
As described above, according to the bogie outrigger device of the present invention, the position of the grounding height of the grounding plates 13a of the left and right support arms 13 on the ground is automatically adjusted by the grounding height automatic adjustment mechanism 14. Since the cart 4 is set in parallel, even when the support arm 13 is grounded on the ground, the ground plate 13a of the support arm 13 can be reliably grounded on the ground even if the ground has irregularities. Paralleling can be performed easily and easily, so that the cart 4 can be stably placed on the ground.
[0031]
Further, according to the bogie outrigger device of the present invention, the structure of the automatic grounding height adjustment mechanism can be simplified, and the manufacturing cost can be reduced.
[0032]
【The invention's effect】
As is clear from the above description, according to the invention of claim 1, a pair of right and left mounting brackets respectively fixed to the outside of the bogie on the left and right sides of the rear end of the bogie are provided. A semicircular rotating body rotatably supported by each of the mounting brackets; and right and left support arms having base ends connected and fixed to the rotating bodies, and having a ground plate at a distal end. The height position of the ground plate at the tip of the support arm disposed between the bracket and the rotating body and fixedly connected to the rotating body is automatically adjusted according to the height of the ground, and the bogie is parallelized. The grounding height automatic adjustment mechanism ensures that the grounding height automatic adjustment mechanism automatically adjusts the grounding height position of the support arm when the support arm is grounded to the ground, even if the ground has irregularities. So, set the cart parallel Single, can be easily performed, thereby a stable state the dolly may be placed on the ground.
[0033]
According to the invention of claim 2, the automatic ground contact height adjusting mechanism is provided between the mounting bracket and the rotating body, and the storage positioning tapered hole for fixing the support arm to the storage position in the rotating body. And, an adjustment positioning taper hole for automatically adjusting the ground height position of the ground plate of the support arm to parallelize the carriage is provided, while the mounting bracket has a storage positioning taper hole formed in the rotating body. By providing a locking device having a tapered locking member that can be removably engaged with the adjustment positioning taper hole, the locking device is provided regardless of the level of unevenness of the ground on which the truck 4 is installed. Is supported by the adjustment positioning taper hole formed in the rotating body, so that the truck can be stably placed on the ground.
[0034]
According to the third aspect of the present invention, the locking device connects the tapered locking body to the operating shaft and connects the tapered locking body to the housing positioning taper hole and the adjustment positioning taper hole of the rotating body via the operating shaft. Since it is composed of an urging member for urging toward the head and a case in which the tapered locking member, the operating shaft and the urging member are accommodated, the structure of the automatic adjustment mechanism of the contact height can be simplified. In addition, the manufacturing cost can be reduced.
