Description

一种地面找平研磨机 技术领域
本发明涉及一种地面研磨施工装置，具体涉及一种地面找平研磨机。
 背景技术
地面找平机是集快速密封固化剂地坪、硬化地坪、环氧地坪处理、石材翻新、混凝土整平、打磨，抛光等不同工艺的于一体的多功能机器设备，具有轻便、灵活，工作效率高等特点。
现有技术中，多组研磨盘的研磨机大都采用了皮带传动带动多个研磨盘，如中国专利CN107073672B，采用皮带传动，在研磨阻力较大的地面时，皮带容易打滑，造成地面研磨不均匀，这就导致了研磨效率较低，甚至需要二次研磨，并且三个研磨盘的周向公转为垂直电机直接带动研磨盘边缘转动，由于垂直电机安装在边缘，可造成研磨盘重力不均衡，研磨偏斜的问题。
另外，现有技术中采用独立驱动装置带动多个研磨盘自转与公转，在研磨地面时独立驱动装置扭矩较小，不适宜地面研磨阻力较大的环境。
 技术问题
本发明的目的就是针对现有技术存在的缺陷，提供一种地面找平研磨机，解决了现有技术中多盘研磨皮带打滑，三个研磨盘周向公转受力不均衡，且扭矩小、动力不足的问题。
 技术解决方案
其技术方案是：一种地面找平研磨机，包括主电机连接盘，所述的主电机连接盘的盘面垂直中心位置设有圆形通道，所述的圆形通道的中段垂直设有主动轴，所述的主动轴上部与主电机连接盘形成相对旋转连接，所述的主动轴外套设有可相对其转动的空心轴套，所述的空心轴套的中段外围固定安装蜗轮，所述蜗轮上部与下部的空心轴套外围与主电机连接盘形成相对旋转连接，所述的空心轴套的下表面与齿轮箱的上表面固定安装，所述的主电机连接盘的下部设有蜗杆传动箱，所述的蜗杆传动箱内水平安装蜗杆，所述的蜗轮与所述的蜗杆相啮合，所述的蜗杆传动箱上安装第二电机，所述的第二电机驱动蜗杆转动，所述的主动轴的上端设有盲孔，所述的主电机连接盘的上部表面安装第一电机，所述的盲孔内安装第一电机输出轴，所述的主动轴的下端同轴固定主动齿轮，所述主动齿轮上部与下部的主动轴外围与齿轮箱形成相对旋转连接，所述的主动齿轮与中间齿轮啮合，所述中间齿轮的中轴与齿轮箱形成相对旋转连接，所述的中间齿轮与从动齿轮啮合，所述从动齿轮的中轴与齿轮箱形成相对旋转连接，所述的从动齿轮输出轴上安装研磨盘。齿轮箱的转动采用独立式驱动，并且采用蜗轮蜗杆的传动方式，在不影响单个研磨盘自转的情况下，增大了三个研磨盘公转的扭矩，并且可实现齿轮箱任意方向的旋转。
进一步，所述的主动轴上部安装第三轴承，所述的第三轴承与主电机连接盘形成相对旋转连接；所述蜗轮上部的空心轴套外围安装第一轴承，所述蜗轮下部的空心轴套外围安装第二轴承，所述的第一轴承、第二轴承分别与主电机连接盘形成相对旋转连接；所述主动齿轮上部与下部分别安装主动齿轴承，所述的主动齿轴承与齿轮箱形成相对旋转连接；所述中间齿轮上部与下部分别安装中间齿轴承，所述的中间齿轴承与齿轮箱形成相对旋转连接；所述从动齿轮上部与下部分别安装从动齿轴承，所述的从动齿轴承与齿轮箱形成相对旋转连接。转动连接部位采用轴承连接，减小转动阻力。
进一步，所述的轴承为圆锥滚子轴承。齿轮由圆锥滚子轴承夹持，即可以承受径向负荷，又可以承受轴向负荷。
进一步优选，以所述的主电机连接盘为中心，所述的蜗杆传动箱径向对称位置设有配重安装装置，所述的配重安装装置上设有与第二电机安装位置相反的配重块。采用配重安装装置，蜗杆传动箱用于安装驱动装置，配重安装装置用于安装配重块，使蜗杆传动箱与配重安装装置重力相同，最终使齿轮箱的整体转动的配重均衡。
进一步优选，所述的从动齿轮为三个，周向均匀安装在齿轮箱内。采用三个从动齿轮，每个从动齿轮安装研磨盘，每个研磨盘之间的角度呈120°均匀分布在齿轮箱内，对地面均匀磨削。
本发明与现有技术相比较，具有以下优点：设计合理，动作可靠，公转与自转分别采用不同的电机驱动，扭矩大；研磨盘采用齿轮传动，对于研磨阻力大时不会打滑；第二电机径向对称位置设有配重块，使齿轮箱整体配重均衡，不会偏向一侧研磨，并且可实现齿轮箱任意方向的旋转。
