As mentioned above, in the transmission position, the flexible shaft is engaged between the cutting motor and the cutting disk, and in the separation position, the flexible shaft and the cutting disk are separated. By adopting the clutch mechanism of the coal shearer according to the embodiment of the present disclosure, the failure rate of the coal shearer can be reduced and the continuity of the operation can be improved.
下面描述本公开实施例的离合机构使用方法。The following describes how to use the clutch mechanism of the embodiment of the present disclosure.
本公开实施例的离合机构使用方法包括以下步骤：The method of using the clutch mechanism in the embodiment of the present disclosure includes the following steps:
S1：将柔性轴2切换至传动位置，并将顶推组件7固定在定位组件3上。例如，可以首先驱动底座6向左移动，并直接将底座6和定位盖31贴合，拉杆4会随着底座6同步移动，柔性轴2则可以在拉杆4的作用下被切换至传动位置。然后可以将顶推组件7的架体73与定位盘32安装固定。S1: Switch the flexible shaft 2 to the transmission position, and fix the push component 7 on the positioning component 3. For example, you can first drive the base 6 to move to the left, and directly fit the base 6 and the positioning cover 31. The pull rod 4 will move synchronously with the base 6, and the flexible shaft 2 can be switched to the transmission position under the action of the pull rod 4. Then, the frame 73 of the pushing assembly 7 and the positioning plate 32 can be installed and fixed.
S2：启动采煤机的截割盘。例如，可以驱动截割电机1低功率运行，从而可以提升作业的安全性，通过柔性轴2的传动可以实现截割电机1对截割盘的驱动。S2: Start the cutting disc of the shearer. For example, the cutting motor 1 can be driven to run at low power, thereby improving the safety of the operation. The cutting motor 1 can drive the cutting disk through the transmission of the flexible shaft 2 .

The rotation adjustment position of the push piece 72 can achieve quantitative adjustment, for example, the push piece 72 can be rotated with a wrench or the like. The overall length of 72 can be constant. After the pushing member 72 rotates to the left and moves into place, the leftward movement distance of the pushing member 72 can be determined by measuring the length of the right portion of the pushing member 72 located on the frame 73. This enables intuitive monitoring of the force between the push piece 72 and the pull rod 4 and the adjustment of the position of the bearing 5 between the pull rod 4 and the flexible shaft 2, thus facilitating the adjustment in place.
S4：待截割盘运行稳定后，将顶推件72固定。例如，可以驱动截割盘运行一段时间，在该时间段内，若截割盘运行稳定、无障碍即可。然后可以通过旋转螺母将顶推件72安装固定。S4: After the cutting disc runs stably, fix the pusher 72. For example, the cutting disk can be driven to run for a period of time. During this period, it is sufficient if the cutting disk operates stably and without any obstacles. Then the pushing member 72 can be installed and fixed by rotating the nut.
S5：待截割作业完成后，拆除顶推组件7并将柔性轴2切换至分离位置。从而可以避免误启动而容易造成安全事故的情况。 S5: After the cutting operation is completed, remove the push assembly 7 and switch the flexible shaft 2 to the separation position. This can avoid accidental starts that may easily cause safety accidents.
