At present, the digger engine arrangement is for to be surrounded by dividing plate, form the engine room of a sealing, only open heat elimination hole at machine overhead guard and bottom plate, be used for heat radiation, the hot blast that can avoid like this engine blower to blow out heats the hydraulic pressure components and parts, thus the phenomenon such as the shake of the equipment that can avoid occurring owing to hydraulic oil temperature is too high and complete machine be unable.This arrangement is conducive to the excavator normal operation under normal operation, but when cold in the winter time, the viscosity with temperature of the used hydraulic oil of hydraulic crawler excavator reduces and descends, cause the resistance increment that flows, hydraulic pump is inhaled the phenomenons such as sky, equipment shake, Hydraulic Elements clamping stagnation when thereby work occurring, affects the normal use of excavator.
When heat engine, the engine room closure solutions can effectively stop the engine room hot blast that hydraulic part is heated, but because engine room sealing, can't carry out preheating to hydraulic oil when cold in the winter time.When the preheating excavator, can use room heater that excavator is carried out preheating at present, and cover radiator with anti-cold cover, realize that the pre-heat effect of hydraulic oil is limited when said method is cold in the winter time.
Summary of the invention
For the problem of above-mentioned existence, the purpose of this invention is to provide a kind of device that strengthens pre-heating function of hydraulic oil, solved that winter is cold because hydraulic oil is difficult to carry out the problems such as excavator action clamping stagnation that preheating causes.
The objective of the invention is to be achieved through the following technical solutions:
A kind of device that strengthens pre-heating function of hydraulic oil, cooperatively interact with the motor that is positioned at engine room, radiator, fan, to realize pre-heating function of hydraulic oil, wherein, the folding window that comprises the tape-select switch that described engine room is provided with towards an end of hydraulic oil container, also comprise controller and temperature pick up, described controller connects respectively described temperature pick up and described selector switch, and described temperature pick up is located on the hydraulic oil container;
When described engine start, by described selector switch described folding window is opened, described fan with wind from the outside in described radiator sucks described engine room; Described motor is in running, and the heat of generation flows to hydraulic oil container through described folding window, and hydraulic oil container is carried out preheating; When the temperature of the hydraulic oil in the hydraulic oil container rose to the first temperature value, described temperature pick up feedback signal was to described controller, after described controller receives signal, process by internal processes, automatically described folding window is closed, stop hydraulic oil heating, shorten excavator preheating time.
The device of above-mentioned enhancing pre-heating function of hydraulic oil, wherein, the operating temperature that described hydraulic oil is suitable is 40 ℃ to 50 ℃.
The device of above-mentioned enhancing pre-heating function of hydraulic oil, wherein, after stopping the hydraulic oil heating, described controller continues to collect signal according to described temperature pick up, when hydraulic fluid temperature is lower than the second temperature value, automatically open described folding window by described selector switch.
The device of above-mentioned enhancing pre-heating function of hydraulic oil, wherein, described folding window is shutter.
The device of above-mentioned enhancing pre-heating function of hydraulic oil, wherein, described engine room is rectangular, and described folding window is positioned on the corner of described engine room.
The device of above-mentioned enhancing pre-heating function of hydraulic oil, wherein, described radiator overcoat has anti-cold cover.
Compared with the prior art, beneficial effect of the present invention is: by the open and close of shutter, the heat that utilizes extraneous wind energy to drive engine room flows to hydraulic oil container, hydraulic oil is carried out preheating, when cold in the winter time, can prevent effectively that hydraulic oil viscosity from increasing and when work occurring hydraulic pump inhale the phenomenons such as sky, equipment shake, Hydraulic Elements clamping stagnation.
Description of drawings
Fig. 1 is the structural representation that the present invention strengthens the device of pre-heating function of hydraulic oil.
The specific embodiment
The invention will be further described below in conjunction with schematic diagram and concrete operations embodiment.
As shown in Figure 1, the present invention strengthens the device of pre-heating function of hydraulic oil, cooperatively interact with the motor 4 that is positioned at engine room 3, radiator 1, fan 2, to realize pre-heating function of hydraulic oil, the folding window 5 that comprises the tape-select switch (not marking in the drawings) that engine room 3 is provided with towards an end of hydraulic oil container 7, also comprise controller 8 and temperature pick up 6, controller 8 connects respectively temperature pick up 6 and selector switch, and temperature pick up 6 is located on the hydraulic oil container 7.
Further, folding window 5 is shutter, specifically can be the dividing plate with shutter, and this shutter is easy to obtain for common on the market, is beneficial to realization of the present invention.
Further, engine room 3 is rectangular, and folding window 5 just is positioned on the corner of engine room 3.The position adjacent with hydraulic oil container 7 that be comparatively common engine room 3, this position.
When cold in the winter time, because temperature is extremely low, hydraulic oil viscosity increases, and hydraulic pump is inhaled the phenomenons such as sky, equipment shake, Hydraulic Elements clamping stagnation in the time of can work occurring.When motor 4 starts, by selector switch folding window 5 to be opened, fan 2 sucks wind in the engine room 3 from the outside through radiator 1.Motor 4 is in running, the heat that produces flows to hydraulic oil container 7 through folding window 5, hydraulic oil container 7 is carried out preheating, when the temperature of the hydraulic oil in the hydraulic oil container 7 rises to suitable operating temperature, temperature pick up 6 feedback signals are to controller 8, after controller 8 receives signal, process by internal processes, automatically folding window 5 is closed, stop the hydraulic oil heating, thereby form the engine room 3 that seals, stop hot blast further hydraulic oil to be heated, shorten excavator preheating time, save fuel oil, be beneficial to the excavator normal operation.
In addition, after stopping the hydraulic oil heating, described controller continues to collect signal according to described temperature pick up, when hydraulic fluid temperature is lower than the second temperature value, automatically opens the folding window by selector switch, realizes complete automatic switch shutter.
