The invention relates to a cleaning machine with overload protection. It includes a frame and a driving shaft. The two sides of the upper end of the frame are respectively installed with a tensioning bracket. The tensioning bracket is installed with a tensioning seat. The left and right ends of the driving shaft are installed on the tensioning seat through bearings. The front end of the tensioning bracket is installed with a pressure sensor. The tensioning seat is connected with the pressure sensor through a tensioning bolt. The lower end of the frame is installed with a driven shaft. The two ends of the driving shaft are respectively installed with a main shaft The driven sprocket is installed at both ends of the driven shaft. The driving sprocket and driven sprocket on the same side of the frame are connected by a chain. There are multiple evenly arranged tine mechanisms on the chain. One end of the driving shaft is connected with a drive motor, which is connected with a pressure sensor. The invention has the advantages of simple structure, the upper end of the frame is provided with the tensioning seat of the driving shaft, the tensioning seat is connected with the pressure sensor through the tensioning bolt, and the pressure sensor is connected with the driving motor, which can effectively prevent the motor from being burnt due to overload, can quickly resume normal operation, reduce the downtime and improve the working efficiency.
【技术实现步骤摘要】
一种具有过载保护的清污机
本专利技术涉及一种清污机,尤其涉及一种具有过载保护的清污机。
技术介绍
目前,回转式清污机作为一种高效、可靠的清污设备在水利工程中广泛应用,其中耙爪机构作为回转式清污机的主要作业部件,耙爪机构在回转中不断与污物、垃圾发生冲击和碰撞,耙爪机构承受较大拉力,而且部分体积大的垃圾会与入水口的墙壁或者清污机的机身摩擦甚至卡死,导致驱动耙爪机构回转的电机过载而烧毁,传统的过载保护装置是在电机连接的链轮上设置额定扭矩的剪断销,当扭矩过大则切断剪断销使得传动环节断开,避免电机因持续过载而烧毁,但是采用剪断销作为保护装置,在清理垃圾后要重新安装剪断销,而链轮拆卸麻烦,停机时间长,严重影响使用。
技术实现思路
针对上述缺陷,本专利技术的目的在于提供一种结构简单,操作方便,能够有效防止电机过载而烧毁,可快速恢复正常作业,减少停机时间,提高工作效率的一种具有过载保护的清污机。为此本专利技术所采用的技术方案是:包括机架和主动轴,所述机架上端两侧分别安装有张紧支架,所述张紧支架上安装有张紧 ...
