Abstract
The utility model discloses a hydraulic oil tank for a cantilever type development machine, composed of a main oil tank and an auxiliary oil tank. The auxiliary oil tank is arranged above the tail portion of the main oil tank and is communicated, an oil suction opening is arranged at one side of the auxiliary oil tank, an oil return opening is arranged at the bottom of the main oil tank, and the tops of the main oil tank and the auxiliary oil tank are separately provided with a main refill opening and an auxiliary refill opening. According to the utility model, oil can be supplied normally to a hydraulic system when going downhill; the adaptive ability of the development to the environment is improved; the structure is novel and unique, the use effect is superior; and the structure is simple and the manufacture cost is low.
Description
Technical field
The utility model relates to a kind of boom-type roadheader, the hydraulic oil container that a kind of specifically boom-type roadheader is used.
Technical background
Boom-type roadheader is a kind of efficient heading equipment that integrates cutting, loading, transhipment rock ballast etc., is widely used in fields such as traffic, tunnel, mining.Compare with large-scale development machine, little, the lightweight characteristics of volume are arranged, be applicable to the operation of medium and small colliery, improve the mechanization level.Common boom-type roadheader has only a hydraulic oil container, because fuel tank is flat and long, is difficult to fuel tank is filled it up with fully.The hydraulic system inlet port is located at the fuel tank rear portion usually, and when the development machine descending, because the weight effect, hydraulic oil converges to the fuel tank front portion, and it is empty that the rear portion can become.If the gradient of descending is bigger, can cause can't normal fuel injection, influences the proper functioning of development machine.
Summary of the invention
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, the hydraulic oil container that provides a kind of boom-type roadheader that can guarantee normal fuel injection when descending to use.
The utility model is the deficiency that solves the problems of the technologies described above, the technological scheme that is adopted is: the hydraulic oil container that a kind of boom-type roadheader is used, form by main fuel tank and drop tank, drop tank is arranged on the afterbody top of main fuel tank and communicates, inlet port is arranged on a side of drop tank, return opening is arranged on the main fuel tank bottom, and main fuel tank and drop tank top are respectively equipped with main oil filler and secondary oil filler.
The utility model, because drop tank exceeds and main fuel tank, oil filler from drop tank can add more oil in fuel tank, improve fuel tank liquid level, and the drop tank width is little, little when descending tilts to the influence of drop tank fuel head, can continue to the hydraulic system normal fuel injection, guarantee the development machine proper functioning.Main fuel tank is generally covered by the miscellaneous equipment on the development machine, and oiling is inconvenient, and its main oil filler that is provided with above only uses more for a long time at the fuel tank oil starvation, refuels and can satisfy the demand from secondary oil filler usually.
The beneficial effects of the utility model are:
1, can guarantee when descending to the hydraulic system normal fuel injection.
2, improved the adaptive capacity of development machine to environment.
3, novel structure, uniqueness, using effect is good.
4, simple in structure, low cost of manufacture.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Mark among the figure: 1, main fuel tank, 2, drop tank, 3, inlet port, 4, return opening, 5, main oil filler, 6, secondary oil filler.
Embodiment
As shown in the figure, the hydraulic oil container that a kind of boom-type roadheader is used, form by main fuel tank 1 and drop tank 2, drop tank 2 is arranged on the afterbody top of main fuel tank 1 and communicates, inlet port 3 is arranged on a side of drop tank 2, return opening 4 is arranged on main fuel tank 1 bottom, and main fuel tank 1 and drop tank 2 tops are respectively equipped with main oil filler 5 and secondary oil filler 6.
The utility model, fuel tank oil starvation refuel from main oil filler 5 more for a long time, and normal conditions are refueled from secondary oil filler 6, main fuel tank 1 thoroughly can be filled it up with.Drop tank 2 width are little, and are little to the influence of drop tank 2 fuel heads when descending tilts, and can continue to the hydraulic system normal fuel injection, guarantee the development machine proper functioning.
