Description

建筑工程墙体3D打印机系统 技术领域
本发明涉及3D打印机技术领域，尤其涉及一种建筑工程墙体3D打印机系统。
背景技术
目前墙体主要采用砌筑和砼浇筑方式，尚无适用于3D打印建筑墙体的设备。由于楼层之间的距离不等，整体的楼高不等且楼高较高，如何通过一套设备就可满足任意距离墙体的打印要求，成为要解决的关键问题。
现有3D打印机的打印头均在3D设备内部，对于超出打印设备范围的位置无法按设计进行打印；另外，由于打印头的设计原因，在打印墙体转角时不够美观。
发明内容
本发明为解决上述的不足问题，提供一种建筑工程墙体3D打印机系统。为解决上述技术问题，本发明的技术方案是：建筑工程墙体3D打印机系统，包括打印滑轨、打印头、滑轮小车、反复提升装置和架体；所述反复提升装置安装于所述架体上，与滑轮小车固定连接；两个滑轮小车之间固定有打印滑轨；打印滑轨上滑动安装有打印头。
进一步的，所述反复提升装置包含：丝杆a、丝杆b、电机a、电机b、丝母a、丝母b；两侧的架体均安装有丝杆b，丝杆b的上端连接有电机b，电机b固定在架体上，丝杆b上连接有丝母b，电机a固定在丝母b上，丝杆a的底端与电机a连接，丝杆a上连接有丝母a，丝母a与滑轮小车固定连接，两个滑轮小车之间固定有打印滑轨，打印滑轨上滑动安装有打印头。
进一步的，所述打印头为可旋转打印头。
进一步的，所述可旋转打印头包括支架a和固定于其顶部的支架b，打印头供料装置位于支架a内，并通过支架a底部的轴承a和支架a上侧部的轴承b与支架a转动连接，所述打印头供料装置内固定设有螺旋旋转轴，螺旋旋转轴顶端固定连接于支架b上的旋转电机c，螺旋旋转轴底端穿过位于打印头供料装置底部的齿轮a和轴承a，并延伸至支架a底部，所述齿轮a与设置在旋转电机b上的齿轮b啮合，所述旋转电机b固定于支架a外底部，打印头供料装置底部连接连接管，所述软管上部位于连接管内，旋转电机a固定在支架c的固定板上，所述支架c上部固定于连接管上，所述旋转电机a连接转盘，所述转盘通过固定装置固定于软管上。
进一步的，两侧的架体底部均通过支板安装有丝杆b。
进一步的，电机b通过电机板固定在架体上。
进一步的，电机a通过电机板固定在丝母b上。
进一步的，打印头下端连接刮板。
本发明仅通过一套设备就可满足楼层之间任意距离墙体的打印要求，提高了墙体强度和各项物理指标，提高了施工效率，改善了劳动环境，降低了建筑成本。当打印建筑物或构件超出框架范围时，程序控制旋转电机带动打印头上的软管向里或者向外动作，进行打印建筑物或构件，达到超出框架范围也可以正常打印的目的。同时，旋转的打印头可以在墙体转角时打出圆弧形墙角，使打印出的墙体转角更加美观。

具体实施方式
如图1-图4所示，建筑工程墙体3D打印机系统，包括打印滑轨1、打印头2、滑轮小车3、丝杆a4、丝杆b7、电机a6、电机b5、丝母a10、丝母b9和架体；两侧的架体底部均通过支板8安装有丝杆b7，丝杆b7的上端连接有电机b5，电机b5通过电机板固定在架体上，丝杆b7上连接有丝母b9，电机a6通过电机板固定在丝母b9上，丝杆a4的底端与电机a6连接，丝杆a4上连接有丝母a10，丝母a10与滑轮小车3固定连接，两个滑轮小车3之间固定有打印滑轨1，打印滑轨1上滑动安装有打印头2；打印头2包括支架a18和固定于其顶部的支架b20，打印头供料装置17位于支架a18内，并通过支架a18底部的轴承a14和支架a18上侧部的轴承b19与支架a18转动连接，所述打印头供料装置17内固定设有螺旋旋转轴21，螺旋旋转轴21顶端固定连接于支架b20上的旋转电机c22，螺旋旋转轴21底端穿过位于打印头供料装置17底部的齿轮a15和轴承a14，并延伸至支架a18底部，所述齿轮a15与设置在旋转电机b13上的齿轮b16啮合，所述旋转电机b13固定于支架a18外底部，打印头供料装置17底部连接连接管26，所述软管12上部位于连接管26内，旋转电机a11固定在支架c25的固定板28上，所述支架c25上部固定于连接管26 上，所述旋转电机a11连接转盘27，所述转盘27通过固定装置24固定于软管12上，软管12下端连接刮板23。
打印头2在打印滑轨1上移动打印墙体，电机b5带动丝杆b7旋转，丝杆b7带动丝母b9上升，丝母b9带动电机a6上升到设计位置时，电机b5停止旋转；再由电机a6带动丝杆a4旋转，丝杆a4带动丝母a10上升，丝母a10带动滑轮小车3上升，滑轮小车3带动打印滑轨1继续上升打印直到满足墙体设计高度处停止打印。
支架a18与支架b20连接成为框架并固定在滑轮小车3上，正常在框架范围内的打印时旋转电机a11不动作使打印头处于垂直状态进行打印；当打印建筑物或构件超出框架范围时，程序控制旋转电机a11运转，旋转电机a11带动转盘27转动，从而带动软管12转动，使软管12运动到框架范围以外进行打印。
当打印到墙体转角时，程序控制软管12垂直沿圆弧轨迹运动，在墙体转角处打印出圆弧墙体，同时，旋转电机b13运转，带动软管12以及软管12上的刮板23转动，刮板23的运动轨迹与打印墙体的圆弧转角相同，刮板23对墙体圆弧转角的外表面进行修整，使圆弧形墙角表面更加平整美观。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明披露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
