Belt tensioning automatic control device of belt conveyer

带式输送机皮带张紧自动控制装置

Abstract

本发明公开了一种带式输送机皮带张紧自动控制装置,属带式输送机技术领域。包括卸载滚筒、传动滚筒、动力装置、下托辊、自动感应装置、改向滚筒、张紧滚筒、尾部滚筒、若干组上槽形托辊、拖动装置和皮带;传动滚筒于动力装置连接;张紧滚筒与拖动装置连接;皮带装在尾部滚筒、上槽形托辊、卸载滚筒上,再通过两个传动滚筒、下托辊、改向滚筒和张紧滚筒;自动感应装置装在靠近下皮带处。带式输送机运行中当皮带松弛时,接触自动感应装置下部触点发出信号,启动拖动装置,使张紧滚筒向左移动皮带张紧。当皮带张紧后皮带接触到自动感应装置上部触点,切断拖动装置的电源使拖动装置停止工作,皮带恢复到正常状态。优点是:结构简单,容易安装、调整和拆卸,运行可靠。
The invention discloses a belt tensioning automatic control device of a belt conveyer, belonging to the technical field of belt conveyers. The belt tensioning automatic control device comprises an unloading drum, transmission drums, a power device, a lower supporting roller, an automatic induction device, a turnabout drum, a tensioning drum, a tail drum, a plurality of groups of upper trough supporting rollers, a dragging device and a belt, wherein the transmission drums are connected with the power device; the tensioning drum is connected with the dragging device; the belt is installed on the tail drum, the upper trough supporting rollers and the unloading drum and then passes through the two transmission drums, the lower supporting roller, the turnabout drum and the expansion drum; and the automatic induction device is installed near the lower belt. When the belt is loosened in the running of the belt conveyer, the belt contacts lower contact points of the automatic induction device to give a signal and the dragging device is started so that the tensioning drum moves left and the belt is tensioned; and after the belt is tensioned, the belt contacts upper contact points of the automatic induction device and the power supply of the dragging device is cut so that the dragging device stops working and the belt restores to the normal state. The invention has the advantages of simple structure, easy installation, adjustment and dismounting and reliable running.
