Adjusting device of trowelling plate of ground trowelling machine and ground trowelling machine comprising same
The invention relates to an adjusting device of a trowelling plate of a ground trowelling machine and the ground trowelling machine. The adjusting device comprises a three-degree-of-freedom parallel mechanism and a rack, wherein the parallel mechanism is arranged on the rack and is provided with a movable platform which has two rotational degrees of freedom around an x axis and a y axis and one translational degree of freedom along a z axis; the rack is rotatably connected with an input shaft; one end of the input shaft is provided with a power input unit; a trowelling plate shaft of the trowelling plate positioned below the movable platform penetrates through the movable platform and then is connected with the other end of the input shaft; the trowelling plate shaft is connected with themovable platform in a sliding manner by a sliding bearing; a trowelling plate adjusting sleeve is sheathed outside the trowelling plate shaft positioned at the lower part of the movable platform; andone end of the trowelling plate adjusting sleeve is fixedly connected with the movable platform, and the other end of the trowelling plate adjusting sleeve is connected with a trowelling piece of thetrowelling plate by a trowelling piece inclination adjusting rod. The adjusting device can realize real-time automatic adjustment on swinging of the trowelling plate in two directions and the inclination angle of the trowelling piece on the trowelling plate simultaneously, has the advantages of simple structures, adjustment and decoupling of all degrees of freedom and the like, is easy to controland has wide application prospect.
本发明涉及一种地面抹平机抹盘的调整装置及地面抹平机，该调整装置包括三自由度并联机构和机架；并联机构安装在机架上，其上具有绕x轴和绕y轴的两转动自由度以及沿z轴的一平动自由度的动平台；机架上转动连接一输入轴，输入轴的一端安装有动力输入单元；位于动平台下方的抹盘的抹盘轴穿过动平台后与输入轴的另一端连接，且抹盘轴通过滑动轴承与动平台滑动连接；在位于动平台下部的抹盘轴外套设有抹盘调整套筒，抹盘调整套筒的一端与动平台固定连接，另一端通过抹片倾斜调整杆与抹盘的抹片连接。本发明能够同时实现对抹盘两个方向摆动和抹盘上抹片倾斜角度的实时自动调整，具有结构简单，各自由度调整解耦，控制容易等优点，具有广泛的应用前景。
