Description

一种矿用电梯承接平台及承接方法 技术领域
本发明涉及一种矿用电梯承接平台及承接方法，尤其适用于柔性导轨矿用电梯，也适用于普通平台的搭接，可以起到安全保护、方便载荷进出电梯，同时使矿用电梯门槛尺寸符合电梯安全标准。
 背景技术
随着我国经济建设不断的高速发展，矿山机械和电梯技术的进步，作为矿用提升机和电梯结合的产物——矿用电梯作为一种新型人性化的提升设备也走入矿井提升系统中。矿用电梯是基于常规曳引电梯和绞车罐笼的基础上设计开发的，是将电梯技术引用到矿用提升系统中，采用特殊的钢丝绳做导轨，执行人员、货物等在井下和地面往复运输的新型矿井提升设备，其提升效率明显提高，而且安全可靠性的要求也更高。目前，电梯主要采用与导靴接触紧密的刚性导轨，使得地槛与层门间隙符合电梯安全标准的30mm的要求，但矿井恶劣的环境容易导致导轨倾斜、变形、倾斜或局部凸起，从而造成电梯轿厢卡轨等潜在危险，而且安装上井道壁的强度和施工条件也不允许，因此采用刚性比较大的钢丝绳做柔性导轨，轿厢和平层会有一定的安全距离，这就要求需要一种承接装置连接轿厢和平层满足电梯的安全标准，目前矿井提升系统所采用的承接装置如：罐座、承接粱、摇台和支罐机，都不符合多平台连接的要求，也不适用于柔性导轨矿用电梯的多平台连接。
 技术问题
本发明的目的是要克服现有的技术中的不足，提供一种结构简单、安全性高、动作准确、操作方便的矿用电梯承接平台与承接方法。
技术解决方案
本发明的矿用电梯承接平台，包括固定在轿厢上的动力系统和四连杆结构的承接装置，承接装置上设有与动力系统相连的转动杆；所述的动力系统包括依次固定在轿厢底梁上的防爆电机、上限位开关、下限位开关、主滑轮，防爆电机经缠绕在上面的主钢丝绳与主滑轮连接，主钢丝绳上设置有挡板，所述的主滑轮上开设有双绳槽，主滑轮经副钢丝绳与固定在轿厢侧梁上的副滑轮相连接，副钢丝绳上设有滑动板，滑动板上设有固定转动杆的滑杆；所述的承接装置包括固定在轿厢地槛支架上的支撑架，地槛支架的转轴转动的承接板、承接板的下部设有与支撑架相连的摇杆，摇杆上设有与承接板相连的连杆。
　　所述的转动杆中部开设有套装在滑杆上的条形缺口滑槽；所述的承接板下面设有加强筋，外端设有支撑在摇杆上的支撑板筋。
本发明的矿用电梯承接平台的承接方法：
当电梯轿厢平层时，通过防爆电机驱动主钢丝绳带动主滑轮转动，缠绕在主滑轮上的副钢丝绳带动副滑轮同时转动，滑动板通过上下的运动使滑杆在转动杆的条形缺口滑槽内移动，驱动转动杆和承接板做圆周运动，连杆带动摇杆绕支撑架转动；
当主钢丝绳上的挡板碰到上限位开关时，防爆电机停止转动，摇杆和承接板上的支撑筋板两者端面相贴合，承接板达到设定位置，形成自锁，人员和货物通过承接板进出入电梯轿厢；
当层门和轿厢门关闭时，防爆电机驱动主钢丝绳带动主滑轮向相反方向转动，当挡板碰到下限位开关时，防爆电机停止工作，承接板收回复位。
 有益效果
由于采用了上述技术方案，该承接平台和承接方法能够实现多水平面内搭接平台的可靠承接，保证了载荷进出电梯轿厢的安全，同时使得矿用电梯在层门与轿门结构上符合电梯安全标准，增加了荷载进出轿厢的安全与可靠性，具有结构简单，控制准确，安装维护方便，运行平稳，主要优点有：
(1) 实现了一个平面在不同高度时可以与相应的工作面进行连接，满足了多个水平工作面内与轿厢搭接平台的可靠连接,节省了每个工作水平面的初期投资费；
(2) 承接装置采用四连杆结构，具有自锁功能，增加了荷载进出轿厢的安全与可靠性。
(3) 动力系统采用钢丝绳进行牵引，布置方便，结构简单，使承接平台搭接和回收便捷。
(4) 控制准确，安装维护方便，运行平稳，使电梯运行更加安全可靠。
