如图1所示，本发明所述的升降测试装置使用M12膨胀螺栓通过定位孔8将底座1固定在水泥地面上，保证测试过程的安全。底座1上设有对射传感器4，升降平台9上固定设有马桶坐垫6和高度检测装置7；液压升降支撑前臂2和液压升降支撑后臂3的中间部位通过升降支撑轴10连接，液压升降支撑前臂2的下端与底座1铰接，液压升降支撑前臂2的上端与升降平台9的下表面轨道配合，液压升降支撑后臂3的上端与升降平台9的下表面铰接，液压升降支撑后臂3的下端与底座1轨道配合，液压气缸5的一端与底座1中间的固定轴通过轴承配合，液压气缸5的另一端与升降支撑轴10铰接；液压升降支撑前臂2和 液压升降支撑后臂3形成剪刀差，当液压气缸5伸缩时，液压升降支撑前臂2和液压升降支撑后臂3的夹角会发生变化，起到将升降平台9上升或下降的目的。As shown in Figure 1, the lifting test device of the present invention uses M12 expansion bolts to fix the base 1 on the concrete floor through the positioning holes 8 to ensure the safety of the test process. The base 1 is equipped with a through-beam sensor 4, and the lifting platform 9 is fixed with a toilet seat 6 and a height detection device 7; the middle part of the hydraulic lifting support forearm 2 and the hydraulic lifting support rear arm 3 are connected by a lifting support shaft 10, which is hydraulically lifted The lower end of the supporting forearm 2 is hinged with the base 1, the upper end of the hydraulic lifting support forearm 2 is matched with the lower surface track of the lifting platform 9, the upper end of the hydraulic lifting support rear arm 3 is hinged with the lower surface of the lifting platform 9, and the hydraulic lifting support rear arm 3 The lower end of the hydraulic cylinder 5 is matched with the track of the base 1, one end of the hydraulic cylinder 5 is matched with the fixed shaft in the middle of the base 1 through a bearing, and the other end of the hydraulic cylinder 5 is hinged with the lifting support shaft 10; the hydraulic lifting support forearm 2 and the hydraulic lifting support rear arm 3 are formed There is a difference in scissors. When the hydraulic cylinder 5 expands and contracts, the angle between the hydraulic lifting support forearm 2 and the hydraulic lifting support rear arm 3 will change to achieve the purpose of raising or lowering the lifting platform 9.
对射传感器4、高度检测装置7以及身高测量装置的输出端分别与控制柜的输入端连接，控制柜的输出端与液压气缸5的输入端连接。对射传感器4位于底座1的相对两面，一个发射信号，一个接收信号，当升降平台9的高度发生改变时，液压升降支撑前臂2与底座1的夹角会发生改变，当液压升降支撑前臂2阻挡住对射传感器4的信号时，对射传感器4会立刻通知控制柜，控制柜判断升降平台9的高度达到了极限值最低值，然后控制切断液压气缸5的回路，起到保护作用。升降平台9的高度达到最高值时，就是液压气缸5的活塞伸出到极限最大值时。The output ends of the through-beam sensor 4, the height detection device 7 and the height measurement device are respectively connected to the input end of the control cabinet, and the output end of the control cabinet is connected to the input end of the hydraulic cylinder 5.

When the height of the lifting platform 9 changes, the angle between the hydraulic lifting support forearm 2 and the base 1 will change, when the hydraulic lifting support forearm 2 When the signal of the on-beam sensor 4 is blocked, the on-beam sensor 4 will immediately notify the control cabinet. The control cabinet judges that the height of the lifting platform 9 has reached the lowest limit value, and then controls and cuts off the circuit of the hydraulic cylinder 5 for protection. When the height of the lifting platform 9 reaches the maximum value, it is when the piston of the hydraulic cylinder 5 extends to the maximum limit.
在升降平台9的上表面的高度测量传感器7，可以实时测量升降平台9的高度，发送到控制柜进行显示和记录。The height measuring sensor 7 on the upper surface of the lifting platform 9 can measure the height of the lifting platform 9 in real time, and send it to the control cabinet for display and recording.
