An oil return pipe (7) is connected between the main oil tank and the secondary oil tank, the oil return pipe is provided with the temperature control electromagnetic valve and connected with the filtering net arranged in the main oil tank, an oil conveying pipe (1) is connected between the main oil tank and the secondary oil tank, the oil conveying pipe is provided with an oil pump, the oil conveying pipe is connected with the filtering net arranged in the secondary oil tank, a heating device (9) is arranged in the main oil tank and a cooling device (10) is arranged in the secondary oil tank. The compressed self-circulating device of the oil tank of the ballast raking machine not only can ensure the continuous work of the oil tank of the ballast raking machine for a long time in a normal environment, but also can ensure the work of the oil tank of the ballast raking machine for a long time in a low temperature and high temperature environment. The invention can ensure that a hydraulic system of the ballast raking machine keeps hydraulic oil still working at the setting temperature at any condition, thereby prolonging the service life of hydraulic components, improving the efficiency of the ballast raking machine and reducing the maintenance cost of the ballast raking machine.
Description
Technical field
The present invention relates to the fuel tank circulation means, especially relate to and be used for the compressed self-circulating device that oil tank of ballast raking machine work is used.
Background technique
Ballast scarifier (having another name called loader-digger or bucket loader) generally mostly adopts hydraulic oil to carry out transmission work, for being suitable for, oil tank of ballast raking machine takes off the requirement that quarrel works long hours continuously, the interior hydraulic fluid temperature of oil tank of ballast raking machine prevents owing to can raise gradually, cause the hydraulic actuator enhance faster wear, the seal element season cracking damages, and causes the problem of hydraulic actuator damage and hydraulic system leakage of oil.Oil tank of ballast raking machine mostly is made up of major and minor fuel tank, utilizes major and minor fuel tank circulation, reaches the temperature of the hydraulic oil that reduces main fuel tank.As everyone knows, ballast scarifier is except the operating time is long, ballast scarifier also often will be worked under the rugged environment of high and cold high temperature, when ballast scarifier when psychro-environment is worked, hydraulic fluid temperature is low and become sticky, thereby the hydraulic oil speed that flows can occur and reduce the compression-expansion reduction, cause the transmission pressure of hydraulic system to descend, influence the ability to work of ballast scarifier; When ballast scarifier when hot environment is worked, hydraulic fluid temperature raises, and causes easily that hydraulic element are aging, cracking damages, and causes hydraulic actuator to damage and the hydraulic system leakage of oil.
Summary of the invention
Can not be suitable for the problem that ballast scarifier is worked at oil tank of ballast raking machine in the above-mentioned prior art under high and cold high-temperature severe environment, the invention provides a kind of oil tank of ballast raking machine compressed self-circulating device of oil tank of ballast raking machine that the energy continuous high-efficient works long hours under high and cold high-temperature severe environment of guaranteeing.
The technological scheme that the technical problem to be solved in the present invention is taked is: described compressed self-circulating device of oil tank of ballast raking machine, it comprises main fuel tank, drop tank, temperature control electromagnetic, filter screen, oil pump and connecting pipeline, described connecting pipeline comprises return tube, transport pipe and working tubing, between main fuel tank and drop tank, be connected with return tube, return tube is provided with temperature control electromagnetic, return tube links to each other with the filter screen that is positioned at main fuel tank, between main fuel tank and drop tank, be connected with transport pipe, transport pipe is provided with oil pump, transport pipe links to each other with the filter screen that is positioned at drop tank, in main fuel tank, be provided with heating equipment, in drop tank, be provided with cooling unit.
Described main fuel tank and drop tank can be structure or up-down structure setting side by side, can design main fuel tank and drop tank amount of capacity according to the ballast scarifier of different model, and the capacity of general drop tank is greater than the main fuel tank capacity.
When compressed self-circulating device of oil tank of ballast raking machine of the present invention, when (5 ℃-40 ℃) work under general environment, owing on main fuel tank, be connected with drop tank, and supply with hydraulic actuator hydraulic oil by main fuel tank, the hydraulic oil in the drop tank only with main fuel tank in hydraulic oil filter closed circulation.Utilize the temperature difference of hydraulic pressure, make hydraulic oil exchange automatically mutually in the major and minor fuel tank, when hydraulic oil true temperature in the main fuel tank reaches the hydraulic working oil temperature of setting, temperature control electromagnetic starts work automatically, flow into drop tank after making the interior high temperature hydraulic oil of main fuel tank by strainer filtering, oil pump also starts work simultaneously, and the low temperature hydraulic oil in the drop tank is input in the main fuel tank; When hydraulic oil in the main fuel tank reaches the minimum temperature of setting, temperature control electromagnetic quits work automatically, close return tube, hydraulic fluid temperature meets the setting requirement in the main fuel tank, and ballast scarifier hydraulic system executive component is worked in the hydraulic fluid temperature scope of setting all the time.When oil tank of ballast raking machine compressor self-circulation cold radiator cooler, when under the psychro-environment below-5 ℃, working, because the hydraulic fluid temperature in the major and minor fuel tank all is significantly less than setting temperature, should open the main fuel tank inner heating device this moment, and hydraulic oil in the main fuel tank is heated to more than the setting temperature; When oil tank of ballast raking machine is worked under hot environment more than 40 ℃, because hydraulic fluid temperature is higher than setting temperature in the major and minor fuel tank, the interior cooling unit of open auxiliary fuel tank this moment, hydraulic oil in the drop tank is cooled in the setting temperature, utilize the mutual automatic cycle exchange of major and minor fuel tank hydraulic oil, the interior hydraulic fluid temperature of main fuel tank is reached in the setting temperature.
Compressed self-circulating device of oil tank of ballast raking machine of the present invention, can not only be suitable for oil tank of ballast raking machine long time continuous working under general environment, and can also satisfy the requirement that oil tank of ballast raking machine works long hours under high and cold hot environment, can guarantee that oil tank of ballast raking machine under any circumstance is under the normal state all the time and work, improved hydraulic actuator working life, increase the ballast scarifier working efficiency, reduced the ballast scarifier maintenance cost.
