Problems solved by technology

Traditional articulated dump truck hydraulic oil tanks generally use high-precision oil suction filters to ensure the cleanliness of the oil sucked into the hydraulic system, and do not pay attention to the cleanliness of the interior of the hydraulic oil tank. In this case, the oil suction filter is easy to block, oil suction Increased pressure will have a great impact on the life of the hydraulic system and the oil suction filter. The filter element of the oil suction filter needs to be replaced frequently. It is labor-intensive and time-consuming to discharge all the oil in the hydraulic oil tank

Abstract

A hinge type dumper hydraulic oil tank comprises a hydraulic oil tank body. An oil return cavity is formed in the top face in a cavity body of the hydraulic oil tank body. An oil return pipe communicating with the oil return cavity is arranged on the side face of the oil return cavity. The other end of the oil return pipe communicates with an oil return port, wherein the oil return port is fixed to the side face of the hydraulic oil tank body and is close to the position of the bottom face, and the oil return port communicates with an outer hydraulic system. The hinge type dumper hydraulic oil tank further comprises a plurality of oil return filters. Oil inlets of the oil return filters are arranged in a cavity body of the oil return cavity, and after penetrating out of the bottom face of the oil return cavity, oil outlets of the oil return filters extend towards the cavity body of the hydraulic oil tank body; and the part between the radial outer circumferential face of each oil return filter and the oil return cavity is sealed. The novel hinge type dumper hydraulic oil tank is provided, the hydraulic system oil liquid cleanliness can be achieved, oil suction and return oil filter element replacement is simple, and stable running of the hydraulic system is guaranteed.

Description

technical field [0001] The invention relates to a novel hydraulic oil tank of an articulated dump truck, which belongs to the field of mining machinery. Background technique [0002] Articulated dump truck is a non-highway mining dump truck, which is suitable for harsh environments such as rugged, muddy and narrow roads. In order to meet the conditions of use, articulated trucks are generally six-wheel drive and three-axle brakes. The brakes are mostly wet hydraulic systems. The dynamic and steering systems are all hydraulic steering, so the hydraulic system controls the braking, steering and lifting of the vehicle, and its stability and reliability directly affect the performance and safety of the vehicle. The structure of the main valve and plunger pump used in the hydraulic system of the articulated dump truck is complex, and the precision of the hydraulic oil is very high. As the source of the hydraulic system, the oil tank must meet the requirements of the hydraulic sys...
