Description

导轨承载式直驱提升装置 技术领域
本实用新型涉及一种导轨承载式直驱提升装置,属于升降装置技术领域。
背景技术
现有的传动方式基本有液压传动、螺杆传动、曳引式传动等,结构复杂,占用空间多,安装复杂,需要配重装置、液压缸体及缆绳传动装置等。目前液压传动需要油缸及泵站,油缸需要较高加工质量,需要较多液压油,一般速度较低,且提升高度不高;螺杆传动需要较高加工精度,螺杆对接难度较高,速度较慢,也无法达到较高高度;曳引传动需要配重装置,传动缆绳,主机机房,提升高度越高自身总重量越大,能量损耗越多,提升重量越大需曳引部分静摩擦力越大,因此只能增加曳引绳数量及两侧重物重量,造成能量损耗过多,制造成本增加。目前使用的直齿齿条与齿轮传动,带动箱体运行,滚轮在导轨上滚动,这种曳引方式布局分散,安全性较低,运行噪声,晃动较大,无调速装置只能运行速度较低,一般速度小于0.5m/s,不适合频繁及高精度情形下的提升运行。

优选的,所述的驱动电机为永磁同步电机,向上运行时提供驱动力,并不会上行超速,向下运行驱动电机提供制动力并对外提供电力,因特殊原因,如制动装置失灵,本装置未通电快速下滑时同步电机反向励磁,也防止本装置失速坠落。
优选的,所述的齿槽为连续的波浪线型半圆槽;传动齿为连续的波浪线型半圆凸起,连续的波浪线型半圆槽与连续的波浪线型半圆凸起相配合。齿槽和传动齿均为连续的波浪线型,因此传动过程较为平稳,相对于传统的齿轮齿条传动,本装置的传动噪音更小,不易晃动。
