Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
It shown in Fig. 1, is the schematic diagram of the utility model one embodiment's lubrication system.This embodiment's lubrication system comprises grease pump 1, at least two branch roads that are set up in parallel and control valve 2.Wherein grease pump 1 is for pumping lubricating grease from depot fat bucket 6, and it can be hand pump, can be also motor-drive pump or other structure, and the utility model is not limited to this.
Each branch road is connected in the outlet of grease pump 1 side by side, and when lubricated, lubricating grease can flow out to lubricating point from the outlet of each branch road.In the embodiment shown in fig. 1, be provided with 4 branch roads (should be understood that, branch road can also be other multiple possible quantity).Correspondingly, the quantity of control valve 2 is consistent with the quantity of branch road, is also 4.Each control valve 2 is arranged on each branch road, for controlling respectively the break-make of each branch road.
This embodiment is because one control valve of route 2 is controlled its break-make, therefore easier on controlling, and is convenient in an orderly manner each lubricating point is lubricated to processing.Each branch road can be arranged on corresponding structure member, and pipe-line layout is comparatively simple.The outlet of each branch road can be the outlet on grease tube road, by this outlet, directly to corresponding lubricating point, provides lubricating grease.The outlet of each branch road can be only one, and preferably its quantity is a plurality of, so that every branch road all can be realized the lubricated of a plurality of lubricating points.
Preferably, be provided with distributing valve 3 on each branch road, the entrance of this distributing valve 3 connects the outlet of control valve 2, and the outlet of distributing valve 3 can be flowed out lubricating grease.This distributing valve 3 can have multiple possible structure, and preferably as shown in Figure 1, this distributing valve 3 is multi-layer structure, and lubricating grease can pass through each layer of distributing valve 3 successively, and each layer of distributing valve 3 is provided with outlet.Aforementioned distributing valve 3 is laddering distributing valve, and each layer is preferably provided with two outlets, and each outlet can connect the structures such as oil nozzle.
Those skilled in the art can be according to lubricating point quantity in concrete application and the required number of plies of lubricating grease amount choose reasonable distributing valve 3 and the latus rectum of each outlet of each lubricating point.Be connected in pipeline between aforementioned grease pump 1, control valve 2 and distributing valve 3 according to actual needs choose reasonable be lubricating grease steel pipe or flexible pipe.
This control valve 2 can be for comprising electromagnet cut off valve, fluid-controlled cut-off valve or the pneumatic stopping valve etc. of on state and cut-off state.In the embodiment shown in fig. 1, control valve 2 is electromagnet cut off valve (two position two-way valve), can realize the first state of conducting and the second state of cut-off.The break-make of this solenoid valve can be controlled by artificial command signal, also can realize automatic control.In the embodiment shown in Figure 2, this control valve 2 is fluid-controlled cut-off valve, can control by independent hydraulic control oil circuit the state of this control valve 2.
Further, in order to improve lubrication effect, can realize motion and lubricated synchronizeing, need lubricated and when the moving element associated with lubricating point moves, control valve 2 is realized on state.
Such as, take concrete mixer as example, lubrication system can comprise the first branch road, the second branch road, the 3rd branch road and the 4th branch road, each branch road is arranged at respectively on first segment arm, second section arm, the 3rd joint arm and the 4th joint arm.
When monitoring the concrete of construction institute pumping, reached after certain side's amount, now pump truck need to be lubricated processing.If first segment arm swing only detected, initial lubrication fat pump 1, and the first branch road is communicated with, other branch road is cut-off state, now can to first segment arm swing associated to hinged place be lubricated processing, because jib carries out the lubricated of respective hinge place when swinging, when static with respect to jib, for lubricated technological scheme, can improve the lubrication effect of hinged place.
In addition, in the embodiment shown in Fig. 1 and Fig. 2, lubrication system also comprises filter 4, and filter 4 is connected between the outlet of grease pump 1 and the import of each branch road.The quantity of this filter 4 is preferably 1, before lubricating grease enters each branch road, lubricating grease is carried out to filtration treatment, and the turbidity test that improved lubricating grease are good, and impurity is sneaked into the probability of stopping up of oil channel and greatly reduced.
In this lubrication system, relief valve 5 can also be set, the entrance of relief valve 5 connects the outlet of grease pump 1, and the outlet of relief valve 5 connects depot fat bucket 6.This relief valve 5 is Normally closed type structure, and when the pressure of grease pump 1 outlet is greater than the cracking pressure of relief valve 5, lubricating grease leaks into depot fat bucket 6, thereby has avoided the damage that system caused because pressure is excessive.
Except the lubrication system of previous embodiment, the utility model also provides a kind of multistage beam mechanism that is provided with aforementioned lubrication system.This multistage beam mechanism comprises at least two joint joint arms, and between adjacent segments arm, head and the tail are hinged, and the outlet of each branch road is connected in the hinged place of multistage beam mechanism.Between adjacent segments arm, oil cylinder and connecting rod can also be set, to drive the relative swing between joint arm.The hinged place of aforementioned multistage beam mechanism can be the hinge on oil cylinder, connecting rod or joint arm.
Preferably, the joint quantity of arm and the quantity of branch road are consistent.According to the concrete application of multistage beam mechanism, the quantity of joint arm is preferably 3-6 joint.On each joint joint arm, be provided with a branch road, thus can be so that the pipe-line layout of lubrication system.
Oil cylinder on multistage beam mechanism generally comprises a plurality of, and the action of oil cylinder is controlled by multi-way valve, and multistage beam mechanism also comprises with multi-way valve and be connected controller with control valve 2, and controller, according to the state of multi-way valve, is controlled the break-make of each control valve 2.As previously mentioned, if according to the state of multi-way valve, judge only first segment arm swing, by controller, automatically control each control valve, the first branch road is communicated with, other branch road is cut-off state, thereby realizes jib motion and lubricated the synchronizeing of hinge.
The utility model also provides a kind of engineering machinery, and this project machinery is provided with lubrication system or the multistage beam mechanism of previous embodiment.This project machinery can be provided with the equipment of multistage jib for concrete mixer, concrete placing boom, wet-spraying machine etc., with a plurality of lubricating points to wherein, be lubricated processing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
