Description

一种液压钳盘安全制动器 技术领域
本实用新型涉及起重、运输设备驱动装置的制动器，具体为一种液压钳盘安全制动器。
背景技术
目前，起重、运输设备驱动装置的制动器除了在高速端安装工作制动器外，通常要求在驱动装置的末端(低速端)安装紧急安全制动器，以保证设备的安全。(低速端)紧急安全制动器要求是失效制动，也就是要求在系统故障状态下，失效能自行制动，保证设备安全。目前采用弹簧实施制动是很有效的方法。由于是在驱动装置的末端(低速端)，则需要足够大的制动力，也就需要有足够大的驱动力源克服弹簧压力打开制动器。但在制动器领域，现在所采用的(低速端)安装紧急安全制动器，全部采用液压系统(气压系统)作为驱动动力源的液压(气动)缸钳式制动器。却无法采用电力液压推动器或电磁铁等作为制动器的驱动动力源，这样存在的技术问题有：
一、采用现有的电力液压推动器或电磁铁等作为制动器的驱动动力源的制动器制动力矩非常有限，无法满足大力矩的制动要求。
二、外形尺寸庞大，占用空间大。
三、采用液压系统(气压系统)作为驱动动力源的液压(气动)缸钳式制动器，存在系统复杂、控制点多、维护困难的问题。
四、系统容易泄漏，维护难度大，生产成本高。

本实用新型中，所述安装板和机架之间采用筋板焊接或销轴连接。所述上杠杆臂通过销轴固定在所述机架上，所述下杠杆臂通过销轴固定在下杠杆臂支座上，所述下杠杆臂支座固定在所述机架上。
有益效果
本实用新型利用较小的推动器推力，通过多级杠杆的巧妙组合，实现大的夹紧力。达到失效保护制动，保证起重、运输设备的安全。且结构简单、空间尺寸小，安装方便，维护简单，安全可靠，避免了带液压系统的钳盘制动器的电磁阀失效而导致的无法泄压制动的故 障和安全隐患。
