技术领域technical field
本发明涉及作业机械技术领域，尤其涉及一种作业机械。The invention relates to the technical field of working machines, in particular to a working machine.
背景技术Background technique
作业机械是装备工业当中的重要组成部分，主要用于土石施工、路面养护、起重装卸、消防作业等，从而作业机械按照类别可分为起重机械、桩工机械、路面机械、压实机械、消防车等。Working machinery is an important part of the equipment industry. It is mainly used for earth and stone construction, road maintenance, lifting and loading, fire fighting, etc., so the working machinery can be divided into lifting machinery, pile machinery, road machinery, compaction machinery according to categories. , fire trucks, etc.
对于需要回转作业的作业机械而言，转台是其重要组成部分，转台的上部与臂架的端部铰接，转台的下部与回转支承结构固定，回转支承结构则安装于固定转塔上。在回转作业时，转台及回转支承结构在驱动机构的驱动下相对于固定转塔在水平面上回转，从而可使得臂架的末端到达不同作业位置。与此同时，转台的上部还铰接变幅机构的固定端，变幅机构的伸缩端铰接于臂架上，从而可通过控制变幅机构的伸缩来改变臂架的俯仰角度。For the work machinery that needs to be rotated, the turntable is an important part. The upper part of the turntable is hinged with the end of the boom, and the lower part of the turntable is fixed with the slewing support structure, which is installed on the fixed turret. During the slewing operation, the turntable and the slewing support structure are driven by the drive mechanism to rotate on the horizontal plane relative to the fixed turret, so that the end of the boom can reach different working positions. At the same time, the upper part of the turntable is also hinged to the fixed end of the luffing mechanism, and the telescopic end of the luffing mechanism is hinged to the boom, so that the pitch angle of the boom can be changed by controlling the telescoping of the luffing mechanism.
如图1所示，现有的转台通常包括底板101与侧板102，侧板102安装于底板101上，在侧板102上设置用于与臂架的一端相铰接的臂架铰接孔103，及设置用于与变幅机构的固定端相铰接的变幅机构铰接孔104，并在侧板102上焊装有用于连接底板101的前封板105。然而，这种转台结构设计不合理，臂架铰接孔相对于回转轴线的偏心距离过小，而在将臂架铰接孔相对于回转轴线以较大的偏心距离设置时，前封板与底板之间连接处的受力将发生恶化。As shown in FIG. 1, the existing turntable usually includes a bottom plate 101 and a side plate 102, the side plate 102 is installed on the bottom plate 101, and the arm frame hinge hole 103 for hinged with one end of the arm frame is provided on the side plate 102, A luffing mechanism hinge hole 104 is provided for hinged connection with the fixed end of the luffing mechanism, and a front sealing plate 105 for connecting the bottom plate 101 is welded on the side plate 102 . However, the structure design of this turntable is unreasonable, and the eccentric distance of the hinge hole of the boom relative to the rotation axis is too small. The stress at the connection will deteriorate.
由此可见，现有转台的机械强度差，对转台的偏心设置受到限制，难以充分利用作业机械驾驶室上方的空余空间进行转台的布置，导致严重影 响到臂架的可布长度。It can be seen that the mechanical strength of the existing turntable is poor, the eccentric setting of the turntable is limited, and it is difficult to make full use of the spare space above the cab of the working machine to arrange the turntable, which seriously affects the clothable length of the boom.
