Description

轨道式安全防坠器 技术领域
本发明涉及高空作业防护领域，具体涉及一种轨道式安全防坠器。
背景技术
高空作业，防止作业人员高空坠落为首要重点，防坠器因此产生。
传统技术存在以下技术问题：
市场现有防坠器主要有两类，一类是卡槽宽度固定的防坠器(CN204182046U-一种钢轨防坠器,CN204337548U-一种高空作业防坠落的钢轨防坠器)，其缺点是在过轨道对接处，因为轨道对接处尺寸偏差的缘故，导致具有固定槽宽度的防坠器容易被卡死，而影响作业人员移动，常在作业过程中被作业人员弃用而产生安全隐患。另一类为附带止位插销的活动槽宽防坠器，因止位插销有可能被意外拔出导致承重块弹开脱离轨道，而具有安全隐患。
发明内容
本发明要解决的技术问题是提供一种轨道式安全防坠器，对防坠器槽宽度进行调节的同时保证即使在人为调节槽宽度的过程中依然是安全可靠的，以此为作业人员提供全程不间断的人身安全保障。

具体实施方式
下面结合附图和具体实施例对本发明作进一步说明，以使本领域的技术人员可以更好地理解本发明并能予以实施，但所举实施例不作为对本发明的限定。
参阅图1到图3，一种轨道式安全防坠器，包括：
主承重块，所述主承重块的上端面上设有防坠卡舌通槽110，所述防坠卡舌通槽内设有防坠卡舌销120，所述防坠卡舌销上设有防坠卡舌130，所述防坠卡舌绕所述防坠卡舌销131旋转，所述防坠卡舌在弹性件140的作用下在非外力状态下对T型钢轨表面进行压紧，所述防坠卡舌对T型钢轨表面进行压紧的一端采用凸轮结构141，所述防坠卡舌远离对T型钢轨表面进行压紧的一端设 有挂环142；所述主承重块的下端面上设有第一夹持块150，所述第一夹持块的内壁上设有至少两个第一滚轮151；所述主承重块远离所述防坠卡舌的端面设有至少一个第二滚轮160；所述主承重块的侧壁设有两个导向通槽170；所述导向通槽内设有复位弹簧卡块180；
次承重块，所述次承重块的上端面上设有第二夹持块210，所述第二夹持块的内壁上设有至少两个第三滚轮211；所述次承重块的侧壁上设有两个插入臂220，所述插入臂插入所述导向通槽内；所述插入臂上设有复位弹簧凹槽221；所述复位弹簧凹槽内设有复位弹簧222，所述复位弹簧的一端抵触所述复位弹簧卡块，另一端抵触所述复位弹簧凹槽的侧壁；所述插入臂的自由端设有锁扣通槽223；以及
锁扣组件，所述锁扣组件包括两个锁扣件；所述锁扣件包括一体成型的阻挡块310和按压手柄320；所述阻挡块和按压手柄成L型分布；所述阻挡块和按压手柄的连接处与所述插入臂的自由端铰接；所述阻挡块的自由端是斜面；所述锁扣件还包括锁扣弹簧330；所述锁扣弹簧的一端设置在所述锁扣通槽的侧壁上，另一端设置在所述抵触块上；所述阻挡块在锁扣弹簧的作用下在非外力状态下抵触所述主承重块；所述阻挡块在所述按压手柄受到按压力时置于所述锁扣通槽内；
所述第一夹持块和所述第二夹持块共同夹持T型钢轨。
本发明的有益效果：
对防坠器槽宽度进行调节的同时保证即使在人为调节槽宽度的过程中依然是安全可靠的，以此为作业人员提供全程不间断的人身安全保障。参阅图4到图5，具体地，通过按压手柄受力时，锁扣件发生旋转，阻挡块置于所述锁扣通槽内，同时次承重块与主承重块之间的宽度变大，完成解锁。当按压手柄不受力时，在复位弹簧的作用下，次承重块与主承重块之间的宽度逐渐回到原位，当阻挡块不在导向通槽内时即次承重块与主承重块之间的宽度回到原位，所述 阻挡块在锁扣弹簧的作用下在所述主承重块，完成锁扣。
在其中一个实施例中，所述弹性件是拉紧弹簧。
在其中一个实施例中，所述弹性件是扭簧，所述扭簧被所述防坠卡舌销穿过。
拉紧弹簧的具体实现方式可以参考CN204337548U-一种高空作业防坠落的钢轨防坠器，本申请不再赘述。
由于该钢轨防坠器的防坠卡舌截面曲线采用凸轮结构，较优时采用渐开线式的凸轮结构，当佩戴者不慎跌落时会使防坠卡舌绕卡舌固定销发生旋转,从而使防坠卡舌的凸轮结构随旋转压紧到T型导轨上且愈转愈紧，形成一种通过增大摩擦来防坠的系统。由于为现有技术，可以参考背景技术的两篇专利的相关介绍，本申请不再赘述。
在其中一个实施例中，所述防坠卡舌对T型钢轨表面进行压紧的一端设有滚齿。可以进一步增加防坠卡舌对T型导轨的摩擦力。
在其中一个实施例中，所述两个锁扣件的按压手柄在受到按压力时两者接触。也就是说，所述两个锁扣件的按压手柄搭在一起，这样的话，通过一只手，就可以按压两个锁扣件的按压手柄，进行解锁。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为准。
