Abstract

本实用新型涉及一种刮板机用齿轨销,齿轨(3)与齿轨座(4)由齿轨销(1)定位连接,其特征在于:齿轨销(1)限位孔、限位插销(2)皆为螺纹结构,齿轨销(1)限位孔与限位插销(2)相匹配。使用时将齿轨销用限位插销固定在齿轨座上,让齿轨销与限位插销相互定位,即可以固定齿轨销不再脱落,同时通过螺纹固定了限位插销,简化了限位形式,提高了生产效率,降低了刮板机生产厂家的成本。

Description

刮板机用齿轨销
技术领域
    本实用新型属于煤矿机械设备领域,具体涉及一种刮板机用齿轨销。
背景技术
国内刮板机生产企业所用的齿轨与齿轨座连接主要靠齿轨销定位;在井下生产作业条件复杂恶劣,采煤机采煤时齿轨受冲击载荷大而不均匀,齿轨销若没有限位装置,极易滑动脱落;目前所用的限位装置多为插销限位,可是插销也易脱落,又需要其他的限位装置对它限位,无形中已将问题复杂化了;且井下空间有限,插销的限位实现起来难度很大,同时增加装配工序,给刮板机企业增加了生产成本。
发明内容
   本实用新型的目的是为了克服现有技术的缺陷,提供一种刮板机用齿轨销,从而有效解决了现有技术中存在的问题。
为实现本实用新型的目的采取的技术方案是:一种刮板机用齿轨销,齿轨(3)与齿轨座(4)由齿轨销(1)定位连接,其特征在于:齿轨销(1)限位孔、限位插销 (2)皆为螺纹结构,齿轨销(1)限位孔与限位插销 (2)相匹配。
本实用新型的有益效果是:齿轨销限位孔、限位插销皆为螺纹结构,使用时将齿轨销用限位插销固定在齿轨座上,让齿轨销与限位插销相互定位,即可以固定齿轨销不再脱落,同时通过螺纹固定了限位插销,简化了限位形式,提高了生产效率,降低了刮板机生产厂家的成本。
附图说明
图1为本实用新型示意图;
图2为本实用新型与齿轨座、齿轨装配示意图;
图中:1-齿轨销,2-限位插销,3-齿轨,4-齿轨座。
具体实施方式
以下结合附图对本实用新型的原理和特征进行描述,所举实例只用于解释本实用新型,并非用于限定本实用新型的范围。
实施例1:见图1、2,一种刮板机用齿轨销,齿轨3与齿轨座4由齿轨销1定位连接,其特征在于:齿轨销1限位孔、限位插销 2皆为螺纹结构,齿轨销1限位孔与限位插销 2相匹配。
以上所述仅为本实用新型的较佳实施例,并不用以限制本实用新型,凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。
