Oil sump and a walking construction machine

Abstract

The utility model discloses an oil pan and walking engineering machinery belong to engine technical field, the upper surface of oil pan is equipped with structure outer ring, is equipped with bolt hole on structure outer ring, and the front of left and right sides of oil pan is equipped with bolt bolster, and the rear of oil pan is equipped with bolt bolster, oil pan is metal material and is integrally equipped with longitudinal main reinforcing rib along the extension of oil pan front and back direction and transverse main reinforcing rib along the extension of oil pan left and right direction in the inside corresponding engine cylinder body main bearing cover place, the upper end of longitudinal main reinforcing rib and transverse main reinforcing rib is flush with the upper surface of oil pan, and the lower part of longitudinal main reinforcing rib and transverse main reinforcing rib all is equipped with oil flow passageway, thereby forms the whole and is the upper surface opening and presents honeycomb type structure, and the cavity structure of other each surface closure. The utility model can solve the problem that the engine cylinder body lower end surface design is thick and heavy, and the appearance design of oil pan is complex but the strength is insufficient.
