Abstract

PROBLEM TO BE SOLVED: To develop and provide an engine oil pumping device for a working car working at hillside capable of supplying engine oil to an engine even when the working car inclines, and running the engine continuously. SOLUTION: This engine oil pumping device of the civil engineering working car used for the inclined land work constitutes its characteristic feature of a bottom part of an oil pan 1 of the engine of a working car main body formed in a pyramid shape, a longitudinal oil tank 2 is provided separately from the engine. A hydraulic pump 4 pumps engine oil to an upper part of the oil tank from a pyramid shaped end part 1a of the bottom part of the oil pan through a by-pass 3, and to a pump 7 in the engine through a by-pass 3' through a strainer 6 from a delivery port 5 on the bottom part of the oil tank.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine oil pumping device for a work vehicle used for work on a slope. 2. Description of the Related Art Conventionally, a work vehicle used for work on an inclined ground is suspended from a wire, and moves on a work surface while traveling on an inclined surface within the range, thereby performing work. [0003] However, the work place is a considerable slope, and when the inclination angle is 15 ° or more, the operation of the engine of the work vehicle is stopped, so that it is impossible to continuously operate the work vehicle. . [0004] Originally, engine oil supplied to the engine is stored in a flat oil pan below the engine, and the stored engine oil is pumped and circulated to the engine by a pump to cool the engine. Is what you do. [0005] However, there are 15 working vehicles used for work on slopes.
If it tilts more than °, the suction port of the pump that pumps the oil in the oil pan to the engine comes out above the oil level and sucks air, and the engine oil cannot be pumped and circulated to the engine, causing the engine to burn. (See the dashed line in FIG. 2). [0006] Accordingly, the present invention provides
In order to eliminate these drawbacks, the invention has been invented and is capable of supplying engine oil to the engine even when the inclination angle of the work vehicle is tilted, and the engine oil of the work vehicle used for sloping work where the engine can be continuously operated. Developed pumping equipment
To provide. SUMMARY OF THE INVENTION Accordingly, the present invention provides an oil pan located at a lower portion of an engine in a pyramid shape.
An engine and an engine oil tank are provided separately, and the oil returning to the oil pan is sucked by the oil pump from the bottom of the pyramid-shaped oil pan and pumped to the engine oil tank to enable continuous operation. . DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be described with reference to FIG. 1. FIG. The bottom of the located oil pan (1) is formed in a pyramid shape, and a vertically long oil tank (2) is provided separately from the engine, and the pyramid-shaped end portion (1a) of the bottom of the oil pan (1) is provided. To the upper part of the oil tank (2) via the bypass (3) by the hydraulic pump (4), and from the outlet (5) at the bottom of the oil tank (2) via the strainer (6) to the bypass (3 '). ) And a pump (7) in the engine. According to the present invention, when a work vehicle is working on a slope such as a slope, the vehicle body is greatly inclined, the engine of the work vehicle is inclined, and the oil pan is inclined even if the oil pan is inclined. Since the bottom of the pan (1) is located at the end formed in a pyramid shape, it is always located below the level of engine oil,
The oil tank (2) can be reliably pressure-fed to a separately provided oil tank (2), and since the oil tank (2) has a vertically long shape, even if the vehicle body is greatly inclined, the delivery port (5) is located at the lower part. Since the oil tank is located below the level of the engine oil in the oil tank, it is possible to perform an extremely advantageous effect, such as being able to feed under pressure.
