A trolley frame structure for a paver walking system

Abstract

The invention relates to a trolley frame structure for a paver walking system. The structure includes a box bending plate (2). One end of the box bending plate (2) is connected to a reducer mounting seat (1), and the other end The guide wheel mounting seat (6) is connected, and the two side plates of the bent plate (2) of the box are pierced with a pin sleeve (3) at the end close to the mounting seat (1) of the reducer. The side plate of the bent plate (2) is provided with a mounting plate (5) at one end close to the guide wheel mounting seat (6), and the mounting plate (5) is provided with a plurality of screw holes. The invention relates to a platform frame structure for a paver walking system, which has the advantages of simple structure, low cost, convenient processing, easy assembly and beautiful appearance.

Description

technical field [0001] The invention relates to a trolley frame structure, in particular to a trolley frame structure used on the walking system of a crawler paver, and belongs to the technical field of road surface machinery equipment. Background technique [0002] As the basic structural part of the paver (especially crawler paver) walking system, the trolley frame is the main force-bearing part in the paver. It bears the weight from the whole machine and the paving materials. Walking is realized by the travel drive motor and reducer drive sprocket installed at the rear of the trolley frame. Therefore, whether the structural form of the trolley frame is reasonable or not and whether the trolley frame and the chassis can be assembled directly affect the structure of the whole machine. and the stability of walking work, thus affecting the construction quality of the paver; [0003] At present, the conventional trolley frame generally includes a reducer mounting seat, a guid...

AI Technical Summary

Problems solved by technology

[0003] At present, the conventional trolley frame generally includes a reducer mounting seat, a guide wheel mounting seat, a body upper mounting plate, a body side mounting plate, side plates, left and right beam plates and rib plates, etc., as disclosed in Chinese patent ZL201110393820.8 " A trolley frame" or similar structure used for the walking system of a crawler-type multifunctional paver. The trolley frame of this type of structure has many welded parts, large welding deformation, and difficult to control the welding quality; at the same time, the mounting plate and The machining standard of the mounting plate hole on the side of the main body is not uniform, and it needs to be turned frequently. The machining is difficult and the machining accuracy is difficult to guarantee, which makes the assembly of the trolley frame and the paver frame difficult, which is not conducive to alignment assembly, and seriously affects the paving after assembly. machine construction quality
