The oil-receptacle of building machinery

Technical field

The present invention relates to the oil-receptacle of building machinery.

Background technology

As Fig. 6～shown in Figure 8, be the oil-receptacle that example illustrates existing building machinery with the hydraulic excavator.Fig. 6 is that side view, Fig. 7 of hydraulic excavator is the vertical view of the local section of explanation motor and oil strainer position.

In Fig. 6, hydraulic excavator 1 is equipped with lower running body 4, and the top rotary frame 11 that can rotate freely is installed at substantial middle place, the top of lower running body 4.Be provided with cabin 20 at the rear portion of top rotary frame 11.In Fig. 7, the substantial middle place in cabin 20 is provided with motor 50.The oil strainer of installing in the side of motor 50 (vehicle front side) 55 is installed on the top rotary frame 11 by support 56.

Fig. 8 is the stereogram of the major part seen by arrow P direction among Fig. 6.In Fig. 8, below cabin 20, be provided with the end cover 26 that can form inspection hole 26a.On the inspection hole 26a of end cover 26, but bottom inspection panel 27 is installed as the structure of free switch by hinge 27a.Form by bolt hole 27b on the opposite of the hinge 27a of bottom inspection panel 27 in addition and cover 26 and is connected and the structure of closing at the end.Inspection hole 26a is arranged on can the take apart the engine food tray 51 of bottom and the position of the below of oil strainer 55.

When changing engine oil, the oil tray 80 that maintaining is used is arranged on the ground of the below of release plug 51a and oil strainer 55, and oil that will flow out will pull down the releasing plug 51a of food tray 51 and the oil that flows out among the installing hole 55c from be located at oil strainer cap 55a when pulling down oil strainer 55 are regained together.At this, oil strainer 55 is that filter element and housing are made the device that is integral.

But, when changing above-mentioned existing oil strainer, some problems below existing.

(1) changing the building machinery engine oil often carries out in the very short time of hesitation when the nooning of working site; the oil of heat hangs down through the shell of oil strainer 55 from installing hole 55c when pulling down oil strainer 55 in this case; rotation is also taken off the oil strainer 55 of the heating of this state, and delivering to the oil tray 80 of safeguarding usefulness on the ground must be through very long distance.For this reason, in the time of oil strainer 55 being unscrewed and removing fully, be easy to the clothes of making dirty from installing hole 55c to the oil that oil tray 80 streams of safeguarding usefulness spill, also must hold the oil strainer 55 of heat for a long time, operability is very poor.

(2) pull down after the oil strainer 55 oil (oil that takes out for replacing is called waste oil, and is as follows) that flows out from installing hole 55c till stop to drip, these oil are accepted by the oil tray 80 of safeguarding usefulness.But, because distance from installing hole 55c to the oil tray 80 of safeguarding usefulness, some wind a little, oil just allows wind fall the outside from the oil tray 80 of safeguarding usefulness easily.In addition, will spend long time when the waste oil of having collected is transplanted on the waste oil recycling can of regulation in the oil tray 80 of safeguarding usefulness, this also is a problem.

Summary of the invention

The present invention is conceived to the problems referred to above and develops, and its purpose is to provide a kind of building machinery oil-receptacle of pulling down oil strainer 55 easily and finishing the waste oil recovery of this moment simultaneously at an easy rate in the short time.

In order to achieve the above object, first aspect present invention provides a kind of oil-receptacle of building machinery, when the oil strainer of more reengining, reclaim the waste oil of discharging from the strainer installing hole, its structure is included in the oil tray that cover at the end and end cover is provided with above of the bottom setting of oil strainer.

According to the structure of above-mentioned first aspect,, therefore remove the oil strainer operation and be very easy to owing to can make the oil strainer of dismounting fall into the oil tray that end cover thereunder is provided with above immediately.In addition, since short from the oil of oil strainer installing hole outflow to the distance of fall of oil tray, therefore be not easy the clothes of making dirty, and operability is very good.In addition, because the oil droplet that flows out from the oil strainer installing hole is accepted leaning on than end cover, so be not vulnerable to the influence of wind.Even wind is arranged also because the distance of fall of oil is short, oil droplet can be fallen in the oil tray.In the time that stops to drip up to the oil that flows out, can also carry out other operation simultaneously.Can finish the work of reclaiming waste oil so at an easy rate effectively.

Second kind of structure of building machinery oil-receptacle is to make the structure that escape orifice is set in first kind of structure on oil tray.

If use second kind of structure, at first the ground below escape orifice is provided with the waste oil recycling can, inserts or be screwed into joint at escape orifice.Connect an end of flexible pipe on this joint, the other end of flexible pipe is connected the preparation of carrying out the waste oil recovery with the waste oil recycling can.Then, when oil strainer being pulled down when making its oil tray under directly falling into, the oil that flows out from the oil strainer installing hole just flows into the oil tray, is directly reclaimed by the waste oil recycling can through described joint and flexible pipe.For this reason, just do not need waste oil has been moved on to the work of waste oil recycling can from oil tray.And waiting for that oil flows out in the time that stops to drip from described installing hole, can also carry out other operation simultaneously.This result adds the action effect of first kind of structure, can finish the work of reclaiming waste oil more easily, effectively at short notice.

The third structure of building machinery oil-receptacle is the structure that the controlled valve of disassembled and assembled freely is installed on escape orifice in second kind of structure.

If use the third structure, take off oil strainer in the controlled valve closed condition, make in the oil tray of waste oil under flowing into.Then in this time, in the moment that connects with flexible pipe between with the outlet of controlled valve and waste oil recycling can, open controlled valve and can directly reclaim waste oil.Preparation (oil tray of configuring maintenance maintenance and the be connected the waste oil recycling can) whichever that makes the work of pulling down oil strainer like this and reclaim waste oil is finished earlier, outside oil can not flow to, two operations is carried out simultaneously.This result adds the action effect of second kind of structure, can finish the work of reclaiming waste oil more easily, at short notice.

At first first embodiment is described according to Fig. 1 and Fig. 2 (A), Fig. 2 (B).The stereogram of Fig. 1 for seeing from the motor below of present embodiment, corresponding with the arrow P of Fig. 6 to view.Fig. 2 (A), Fig. 2 (B) are the major part side cross-sectional view, and Fig. 2 (A) is that arrow Q is to view among Fig. 1, and Fig. 2 (B) is the M-M sectional view of Fig. 2 (A).Identical with Fig. 8 in addition building block adopts same sequence number, omits explanation afterwards.

In Fig. 1 and Fig. 2 (A), Fig. 2 (B), below oil strainer 55, extend end cover 26 be set, inspection hole 26a end cover 26 avoid form on the position below the oil strainer 55.In addition, be provided with oil tray 30 above the cover of the end under oil strainer 55 26.When the gib head 31a cards that oil tray 30 forms the upper end at gib headed bolt 31 end around the outer wall at oil tray 30, butterfly nut 32 is threaded in the threaded portion that gib headed bolt 31 bottoms are provided with, thereby oil tray 30 can be installed on the end cover 26 disassembled and assembled freely.

According to first embodiment, when pulling down oil strainer 55, at first pull down oil strainer 55, make simultaneously in its oil tray 30 under falling, so it is short to hold the time of oil strainer 55, remove the good operability of work.Secondly, the oil droplet that flows out from installing hole 55c under end cover 26 above oil tray 30, can in littler distance of fall, finish oily collection.Like this, just be not vulnerable to the influence of wind, thereby can positively in oil tray 30, contain oil.In addition, after oil droplet stops following, butterfly nut 32 unclamped gib headed bolt 31 is pulled down from oil tray 30, can transfer waste oil to the waste oil recycling can from this oil tray 30.Its result makes replacing oil strainer and waste oil at this moment reclaim operation and does not pollute clothes, is easy to finish.

Followingly second embodiment is described according to Fig. 3 and Fig. 4.

Fig. 3 is the major part side cross-sectional view of present embodiment, is arrow Q direction view among Fig. 1.Adopt same sequence number with Fig. 2 (A), structure member that Fig. 2 (B) is identical in addition, omit explanation afterwards.Oil tray 30 becomes one above being fixed on end cover 26 in Fig. 3.On oil tray 30, form escape orifice 30a, be inlaid on the escape orifice 30a in the disassembled and assembled freely mode by the cock 33 that handle has an O RunddichtringO 34 such as screwing togather.

The following describes the effect of present embodiment.At first the escape orifice 30a from oil tray 30 removes cock 33, as shown in Figure 4, joint 35 1 ends is screwed into escape orifice 30a.One end of flexible pipe 36 is installed by clip 37 at the other end of joint 35.The other end of flexible pipe 36 is directly inserted waste oil recycling can (not showing among the figure).Pull down oil strainer 55 then, it is fallen in the oil tray 30.Therefore dismounting work can be carried out very like a cork.Waste oil is short from the distance that installing hole 55c falls in addition, just can not allow in the waste oil inflow oil tray 30 so do not pollute clothes, and not wind-engaging influence and finish oily recovery.

After this, in a single day the oil that flows out from installing hole 55c stops following, and waste oil is recovered to the waste oil recycling can and promptly finishes.Such work before needn't carrying out thus promptly will move on to it waste oil recycling can again behind the oil tray reception waste oil with maintenance usefulness.Can carry out at short notice easily thereby change oil strainer 55 and waste oil recovery operation, improve operation.

In addition, because filling in the oil of 51a (with reference to Fig. 8) outflow from releasing of food tray 51 also flows in the oil tray 30 simultaneously, so can carry out simultaneously from the waste oil recovery of food tray 51 with from two operations of waste oil recovery of oil strainer 55, can finish recovery at short notice, improved operation.

Below in conjunction with Fig. 5 the 3rd embodiment is described.Fig. 5 is the major part side cross-sectional view of present embodiment, be among Fig. 1 arrow Q to view.Identical with Fig. 4 in addition structure member adopts same sequence number, omits explanation afterwards.

As shown in Figure 5, at escape orifice 30a controlled valve 39 (in the drawings for ball valve) is installed, it is designed to: controlled valve 39 closures when control lever 39a is in level (state of representing with solid line); Controlled valve 39 is opened when control lever 39a is in plumbness (state of representing with double dot dash line).One end of flexible pipe 36 is installed in the exit of controlled valve 39 with clip 37, is supporting flexible pipe 36 pars intermedias by the clamp of installing below end cover 26 38, prevents that its leading section is sagging.

According to present embodiment, add the action effect of above-mentioned second embodiment, make the operation of dismounting oil strainer 55 and flexible pipe 36 is taken off insertion waste oil recycling can (not having expression among the figure) from clamp 38, no matter which carries out earlier to open the work of controlled valve 39, and waste oil can be to outflow yet.Thus, described two work just can parallel work-flow, and operation is very good.Its result can finish conscientiously more easily, at short notice and change oil strainer and the waste oil recovery operation of this moment.

Just as described above, according to the present invention,, the distance under the oil droplet is shortened owing to above the cover of the end under oil strainer 26 oil tray 30 is set.Can not pollute clothes like this, pull down oil strainer at an easy rate.And owing to be difficult for the influence of wind-engaging waste oil is flowed in the oil tray 30 effectively, more easily finish waste oil and reclaim.In addition, because oil tray 30 is provided with escape orifice, can be on this escape orifice by disassembled and assembled freely mode jointing and controlled valve, so waste oil can directly be delivered to the recovery of waste oil recycling can via the flexible pipe that is installed on this joint and the controlled valve, can more easily finish the work of reclaiming waste oil at short notice.

At this is that example describes the present invention with the hydraulic excavator, but the present invention is not limited only to hydraulic excavator, and it is widely used in having the building machinery with above-mentioned same oil strainer, can obtain same effect and effect.
