Gravity centre adjustment mechanism for spreader

Abstract

The invention belongs to road engineering machinery and relates to a regulating mechanism for the centre of gravity of a spreading machine. The mechanism includes a pair of sliding tracks longitudinally arranged on a chassis of the spreading machine; and a clump weight which can move backward or forward along the sliding track is arranged between the two sliding tracks, and is driven by a hydraulic cylinder. The hydraulic cylinder is driven by a hydraulic driving device which is controlled by a controller, and a detection signal input part of the controller is connected with a plurality of pressure sensors, which are distributed at the different positions of the caterpillar of the spreading machine. The invention changes the center of gravity of the whole spreading machine by driving the clump weight to move by the hydraulic cylinder, the center of gravity of the spreading machine can be adjusted at any moment according to the spreading width and the change of an ironing board, the adjustment process can be controlled by the controller according to the real-time signal of the pressure sensor, therefore, the adjustment is convenient and reliable.

Description

technical field [0001] The invention belongs to road construction machinery, and relates to a paver center-of-gravity adjustment mechanism. Background technique [0002] The paver is the equipment used for road base and surface paving. It includes a screed installed at the rear of the fuselage. When the width of the paved road changes, it is necessary to increase If the extension screed is installed, the center of gravity of the paver will change accordingly. If the center of gravity is not adjusted, it will cause indentations on the road surface when the paver is stopped to wait for materials, which will seriously affect the quality of the road surface. In this regard, the usual solution is to add corresponding counterweights on the front beam of the paver according to different screed widths, which makes it very labor-intensive and time-consuming to pave roads with variable diameters, and increases the construction cost.
