Bogie frame structure for traveling system of paver

Abstract

The invention relates to a bogie frame structure for a traveling system of a paver. The bogie frame structure comprises a box bend plate (2), and a speed reducer mounting seat (1) is connected to one end of the box bend plate (2) while a guide wheel mounting seat (6) is connected to the other end of the box bend plate (2). A hinge pin sleeve (3) is penetratingly connected to one end, close to the speed reducer mounting seat (1) of each of two side plates of the box bend plate (2). A mounting plate (5) is arranged at one end, close to the guide wheel mounting seat (6), of each of two side plates of the box bend plate (2) and provided with a plurality of screw holes. The bogie frame structure for the traveling system of the paver has the advantages of simple structure, low cost, convenience in machining, easiness in assembly and attractive 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
