具体实施方式:
下面结合附图对本发明做更进一步的解释。
如图 1和 2所示, 电梯防坠系统主要由制动钢丝绳 4构成, 制动钢丝绳 4设置在电 梯 10的两侧, 制动钢丝绳 4的下端通过钢丝绳张紧装置 12固定, 在电梯 10的下端设有 可卡紧制动钢丝绳 4的渐进式安全钳 11。 本发明的基于柔性导向的特种电梯防坠缓冲器 用于连接固定制动钢丝绳 4的上端。
如图 3至 7所示, 本发明的防坠缓冲器 7包括上支撑板 1、 滑轮组 2、 液压阻尼缓冲 器 3、 绳头组合装置 5和下支撑板 6。
下支撑板 6固定在井道 9的矿井顶层平台 8上, 上支撑板 1设置在下支撑板 6的上 方。 滑轮组 2包括设置在下支撑板 6上的一个下部转向滑轮和设置上支撑板 1上且分别 位于下部转向滑轮两侧的两个上部转向滑轮。 在下部转向滑轮一侧的下支撑板 6上开设 一个可使制动钢丝绳 4穿过的通孔, 在下部转向滑轮另一侧的下支撑板 6上设置绳头组 合装置 5。绳头组合装置 5—端通过带有弹簧的螺柱连接固定在下支撑板 6上,绳头组合 装置 5另一端设有滚动滑轮, 制动钢丝绳 4的上端绕过滑轮组 2的各个滑轮后通过绳卡 固定在滚动滑轮上。
液压阻尼缓冲器 3设置在上支撑板 1与下支撑板 6之间。 液压阻尼缓冲器 3包括套 接在一起内液压缸 3-1与外液压缸 3-5, 内液压缸 3-1的上端与上支撑板 1固定,外液压 缸 3-5的上端设置套圈 3-3,保护外液压缸 3-5上端可能因为受到内液压缸 3-1的作用而 产生的变形。 外液压缸 3-5的下端与底座 3-9固定, 底座 3-9与下支撑板 6固定。 内液 压缸 3-1的内腔设置内液压缸活塞 3-4,内液压缸活塞 3-4与内液压缸 3-1的内腔上端之 间设置弹簧 3-2。外液压缸 3-5内腔设置外液压缸活塞 3-6, 外液压缸活塞 3-6与内液压 缸 3-1的下端固定,在外液压缸活塞 3-6的中心穿设带阻尼孔的环形筒 3-7,带阻尼孔的 环形筒 3-7的下端与底座 3-9固定。外液压缸 3-5、外液压缸活塞 3-6和之间形成密封区 域一, 内液压缸 3-1、 内液压缸活塞 3-4和带阻尼孔的环形筒 3-7之间形成密封区域二, 密封区域一与密封区域二之间通过带阻尼孔的环形筒 3-7上的阻尼孔相通, 在密封区域 一和密封区域二内均注满液压油 3-8。
本发明的防坠缓冲器 7的工作原理为:
当电梯 10出现意外时,由于限速器的联动作用,渐进式安全钳 11卡住制动钢丝绳 4, 由于电梯 10的惯性作用, 会通过渐进式安全钳 11对制动钢丝绳 4产生很大的的惯性冲 击力。制动钢丝绳 4将电梯 10的惯性冲击力通过滑轮组 2转移到上支撑板 1上, 使上支 撑板 1挤压内液压缸 3-1向下运动。 内液压缸 3-1通过外液压缸活塞 3-6将密封区域一 内的部分液压油 3-8经带阻尼孔的环形筒 3-7上的阻尼孔挤压至密封区域二内, 动密封 区域二内的液压油 3-8再向上挤压内液压缸活塞 3-4使弹簧 3-2压缩。通过内液压缸 3-1 向下运动过程中阻尼孔的对液压油 3-8的摩擦阻尼作用和弹簧 3-2的进一步压缩, 将电 梯 10的惯性冲击能量转化为阻尼孔和液压油 3-8摩擦产生的热能和弹簧 3-2的弹性势能, 从而实现对制动钢丝绳 4的缓冲保护。而且在电梯 10制动过程中, 通过滑轮组 2使制动 钢丝绳 4的制动距离提高为支撑板 1最大下降距离的 4倍, 通过增加制动钢丝绳 4的制 动距离, 可以有效延长钢丝绳 4的使用寿命。
在电梯制动后, 防坠缓冲器 7的弹簧 3-2所受的力之和为电梯的重力, 其过程为: 电梯制动时, 电梯的速度逐渐减小, 弹簧 3-2收缩, 电梯的动能逐渐转化为液压油 3-8 的热能和弹簧 3-2的势能, 在此过程中, 弹簧 3-2受到的压力逐渐增大, 当弹簧 3-2受 到的力与电梯的重力平衡时, 电梯的动能完全转化为液压油 3-8的热能和弹簧 3-2的势 能, 电梯停止运动。 此时弹簧 3-2虽然还储存能量, 但是由于电梯的平衡作用和液压油 3-8的阻尼作用, 不会回复运动, 因此避免了对电梯造成巨大的反向冲击。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的普通技术人员 来说, 在不脱离本发明原理的前提下, 还可以做出若干改进和润饰, 这些改进和润饰也 应视为本发明的保护范围。
