Boom device and working machine
The invention relates to the technical field of operation machinery, and provides an arm support device and operation machinery, the arm support device comprises at least six arm supports which are sequentially connected, the arm supports can be sequentially folded into at least three rows in the width direction of the operation machinery, the first arm support is connected with a rotary table, and the first to fifth arm supports occupy two rows of spaces; and the sixth section of arm frame is a turning arm frame and occupies the second column of space and the third column of space. The space in the width direction of the operation machine can be effectively utilized, it is guaranteed that the overall height of the operation machine is not too high and the overall length of the operation machine is not too long, meanwhile, the extending arm of the arm support device can be longer, and therefore the conveying height of the operation machine is increased; besides, the width of the arm support does not need to be reduced, so that the section of the arm support is reduced to make space for arranging the added arm support, the rigidity of the arm support is guaranteed, the stress of the arm support is reduced, and therefore a longer arm support or more sections of arm supports can be arranged under the conditions that the rigidity of the arm support is not lost and the stress requirement of the arm support is met.
本发明涉及作业机械技术领域，并提供一种臂架装置及作业机械，包括依次连接的至少六节臂架、并能够沿作业机械的宽度方向依次折叠成至少三列，第一节臂架与转台连接，第一节至第五节所述臂架占据两列空间，且第六节臂架为拐弯臂架，第六节臂架占据第二列空间和第三列空间。可以有效利用作业机械宽度方向的空间，在保证作业机械整车高度不超高和整车长度不超长的同时，可以有利于使臂架装置的展臂更长，从而提高作业机械的输送高度；此外，还可以不用减小臂架的宽度使臂架的截面变小以让出空间来布置增加的臂架，有利于保证臂架的刚性和降低臂架的应力，从而在不损失臂架刚性和满足臂架应力需求的条件下，可以布置更长的臂架或者更多节臂架。
