Drainage ditch excavating device for railway bridge and operation method thereof
The invention discloses a drainage ditch excavating device for a railway bridge and an operation method thereof. The drainage ditch excavating device comprises a vehicle body, wherein a bracket is fixedly mounted at one end of the vehicle body; the bottom of the bracket is fixedly connected with one end of a long hydraulic rod; the other end of the long hydraulic rod is fixedly connected with a cross beam; mounting plates are arranged on the outer walls of the two sides of the cross beam; a moving mechanism is mounted between the mounting plates and the cross beam; a fixed frame is fixedly mounted on the outer sides of the mounting plates; one end of an extension arm is mounted in an inner cavity of the fixed frame; and an excavating wheel is mounted at the other end of the extension arm.The vehicle body is driven to the railway bridge, the cross beam is placed under the bridge by the long hydraulic rod, and the vehicle body moves to the middle part of the bridge surface, so that thecross beam extends into the bottom of the bridge; the moving mechanism drives the mounting plates to horizontally move, so that the extension arm moves to an excavating point and drives the excavatingwheel to vertically extend, and therefore, a drainage ditch is conveniently excavated comprehensively; and the extension arm extends, so that the transmission ratio is low, and therefore, the position of the excavating wheel is controlled more precisely.
本发明公开了一种铁路桥用排水沟挖掘装置及其操作方法，包括车体，车体的一端固定安装支架，支架的底部固定连接长液压杆的一端，长液压杆的另一端固定连接横梁，横梁的两侧外壁均设有安装板，安装板与横梁间安装移动机构，安装板的外侧固定安装固定框，固定框的内腔安装伸展臂的一端，伸展臂的另一端安装挖掘轮。将车体开至一种铁路桥上，长液压杆将横梁放置桥下，车体向桥面中部移动，使得横梁伸入桥底，移动机构带动安装板水平移动，使得伸展臂移动至挖掘点伸展臂带动挖掘轮竖直伸展，便于对排水沟进行全面挖掘，通过伸展臂伸展使得低传动比使得挖掘轮位置控制更精确。
