The invention relates to engineering machinery, in particular to self-driven engineering machinery. The self-driven engineering machinery comprises traveling seats, component force lifting seats, topseats, pressure adjusting mechanisms, a compaction mechanism, flat drawing mechanisms and auxiliary supporting mechanisms. The lower ends of two connecting rods can be far away from each other until two limiting sliding seats respectively abut against the front end and the rear end of a pedestal body, so that triangular structure support is realized, the burden of bidirectional screws is reduced,and the service life of the bidirectional screws is prolonged; the height of the two traveling seats is adjustable, so that one side of the self-driven engineering machinery can ride on a table board,and the other side of the self-driven engineering machinery is positioned on a lower bottom surface, the occupied space of the table board is reduced, and the contact with green belts or trees is avoided; the distance between the two travelling seats is increased, so that the overall standing stability is improved; the distance between the two travelling seats is shortened, so that the travellingseat on one side is close to the travelling seat on the other side to avoid colliding with the green belts or trees; and when the table board with an inclined plane is flattened or compacted, wheelsII can be adjusted to contact with the ground, and supporting points are increased, so that the flattening operation is more stable.

    本发明涉及工程机械,更具体的说是自驱动工程机械。包括行走座、分力抬座、顶座、调压机构、压实机构、平收机构和辅撑机构,两个连杆的下端可相互远离直至两个限滑座分别抵在台座本体的前后两端,进而实现三角结构支撑,减轻双向螺杆的负担,提高其使用寿命;两个行走座的高度可调,便于本发明的一侧骑在台面上,另一侧位于较低的底面上,减少占台面的空间,避免与绿化带或树木接触;增加两个行走座之间的距离可增加整体站立的稳定性,缩短两个行走座之间的距离,进而使位于一侧的行走座向另一侧行走座靠近避免与绿化带或树木相撞;在对斜面的台面进行压平或压实时,可调节轮Ⅱ与地面接触,增加支撑点,使得压平作业更加稳定。
