滑动摩擦机构还包括曲柄滑块机构，曲柄滑块机构包括伺服调速电动机三16、偏心圆盘15、连杆14和外部机架37。外部机架37与机架18固定连接，且外部机架37位于机架18的外侧。伺服调速电动机三16、偏心圆盘15和连杆14设置在外部机架37上，偏心圆盘15的中心与伺服调速电动机三16的输出轴固定连接。偏心圆盘15上开设有多个距离圆心距离不同的螺栓孔，螺纹孔一方面可以通过螺栓连接连杆14和偏心圆盘15，另一方面可以调节刮板6来回滑动的行程。连杆14一端通过螺栓铰接偏心圆盘5，连杆14另一端也以铰接的方式连接有圆柱滑杆一13，保证各构件之间能够在竖直平面内相对转动，以实现该曲柄滑块机构的正常运转。圆柱滑杆一13远离连杆14的一端连接有圆柱滑杆二10，且圆柱滑杆一13与圆柱滑杆二10之间安装有拉压力传感器12。
圆柱滑杆二10固定连接有刮板6，刮板6位于衬板8上，且刮板6底端通过螺栓紧固有刮板试块39，拉压力传感器12的测量值就是刮板6与衬板8往复滑动时的摩擦力。刮板6上端对称设置有两个平面膜盒传感器7，平面膜盒传感器7的测量值就是刮板6所受到的冲击力，平面膜盒传感器7上装有冲击板38以保护传感器，防止传感器损坏。刮板6下端开设有凹槽，且凹槽两端开设有螺纹孔，刮板试块39设置于凹槽中，且刮板试块39通过螺母穿设于螺纹孔中进行夹持。外部机架37上固定安装有滑块一25，圆柱滑杆一13与滑块一25滑动连接。机架18上固定安装有滑块二11，圆柱滑杆二10与滑块二11滑动连接。

一种刮板输送机自检测中部槽装置的检测方法，包括以下步骤：
(1)用天平称量出刮板试块39和衬板8在实验前的重量。
(2)将衬板8水平固定安装在短杆32上，将刮板试块39安装于刮板6的凹槽内并进行固定。
(3)启动伺服调速电动机一22及伺服调速电动机二29，通过调节变频器的频率调节挡板提升输送机2及水平输送机17的运行速度。
(4)在上料料斗1中加入足够的冲击煤料，启动伺服调速电机三16，使整个曲柄滑块机构运转，完成刮板6与衬板8在冲击工况下摩擦运动的模拟。通过拉压力传感器12测得冲击摩擦过程中的摩擦力，通过平面膜盒传感器7测得冲击摩擦过程中的冲击力。
(5)完成参数测量后，停止各伺服调速电机，结束试验，收集试验煤料，并分别用天平称量刮板试块39和衬板8在实验后的重量，就可以计算出冲击摩擦运动的磨损率。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
