The invention provides a rotary encoder protection device. The rotary encoder protection device comprises a rotary encoder body, a mounting part and a protection part, wherein the protection part is of a cylindrical structure formed by welding a hollow seamless steel tube and an end cover in a sealed mode, and the mounting part comprises two fixing plates which are symmetrically welded to the twoends of the side, which is away from the end cover, of the protection part respectively; the rotary encoder body is located in the cylindrical body structure, and the protection device is mounted on acoal mining machine through the fixing plates. According to the rotary encoder protection device provided by the invention, the rear cavity rotary encoder of the coal mining machine is protected andisolated, so that the operation of an electric control element under complex working conditions is ensured, the normal use of the rotary encoder is protected, the service life is prolonged, and the continuity and reliability of automatic mining of the coal mining machine are ensured; and the problems that an existing mounting means does not protect the rotary encoder, the rotary encoder is mountedin a rear cavity of the coal mining machine body, the daily maintenance and overhaul are difficult, the potential safety hazards are large, the wiring positions are prone to damage, and faults are generated are solved.

    本申请提供的旋转编码器保护装置,包括旋转编码器本体、安装部和防护部;防护部为内部中空的无缝钢管与端盖密封焊接而成的柱状体结构,安装部包括两张固定板,分别对称焊接在防护部远离端盖一侧的两端;旋转编码器本体位于柱状体结构中,保护装置通过所述固定板安装在采煤机上。本申请提供的旋转编码器保护装置,通过对于采煤机后腔旋转编码器进行防护、隔离,确保了电控元件在复杂工况下的运行,保护了旋转编码器的正常使用,延长了使用寿命,保证了采煤机自动开采的连续性、可靠性;解决了现有的安装手段没有对旋转编码器进行防护,旋转编码器安装在采煤机机身的后腔,日常维护、检修困难,安全隐患大,接线处容易造成损坏,产生故障的问题。
