Description
Technical field
The utility model relates to a kind of lubricating fitting, particularly relates to a kind of lubricating fitting that is used for concrete pump.
Background technique
In the using process of concrete pump,, particularly, need the configuration lubricating fitting at present in order to guarantee lubricating between the moving elements such as transmission and concrete transmission cylinder and piston in order to guarantee lubricating between each moving element.Known lubricating fitting comprises grease case, unidirectional grease pump, pressure regulator valve, lubricant grease distributor, grease pipe.In the oil-absorbing process of unidirectional grease pump, the grease in the grease case is in the process of unidirectional grease pump pump oil, and grease is pumped in the lubricant grease distributor, and the lubricant grease distributor is assigned to the moving element lubricating point that all need lubricate to grease again.The effect of pressure regulator valve is a pressure of regulating the pumping grease.The shortcoming that adopts this lubricating fitting is that all lubricating points do not have lubricated in unidirectional grease pump pumping process; In lubricant grease pump pumping grease process, all lubricating points are simultaneously lubricated, and the lubricating point that has that have this moment does not need to lubricate, and causes the waste of lubricant grease.Patent documentation is found by retrieval, the patent No. 02277346.0, " a kind of lubricating fitting of concrete pump " by name, and the technological scheme that it is put down in writing is to rely on the two-way grease pump that surges to implement of fixed place and time lubricating.This scheme exists complex structure, cost height, is difficult for problems such as accurately control and waste grease.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of technological scheme that is used for the lubricating fitting of concrete pump, and exist with the solution background technique: in the unidirectional grease pump pumping process, all lubricating points do not have lubricated; In lubricant grease pump pumping grease process, all lubricating points are simultaneously lubricated, and the lubricating point that has that have this moment does not need to lubricate, and causes the waste of lubricant grease; Perhaps rely on the two-way grease pump that surges to implement lubricated existing complex structure of fixed place and time, cost height, be difficult for problems such as accurately control and waste grease.The technological scheme that solves this technical problem employing is: a kind of lubricating fitting that is used for concrete pump, the electronic grease pump of establishing the lubricant grease case in it is characterized in that is provided with two oil outlets, oil outlet connects filter, three-position four-way valve and concrete piston lubricating point successively by pipeline, and three-position four-way valve is communicated with the return opening of electronic grease pump.Wherein, another oil outlet connects the lubricant grease distributor through filter by pipeline, is connected with each lubricating point by pipeline again.Three-position four-way valve is three position four-way electromagnetic valve or 3-position 4-way hydraulic control valve.The beneficial effect that the utility model and background technique comparison are had is: owing to adopt technique scheme, oil outlet 5a with grease pump is connected with the filler opening of filter 3b with lubricant pipe and joint, and the oil outlet of filter 3b is connected with the filler opening of distributor 4.Six oil outlets that distribute 4 are connected with stirring shaft bearing, the big small bearing bracket of " S " pipe valve, each lubricating point of pendulum valve oil cylinder bearing respectively.Another oil outlet 5b is connected with the filler opening of filter 3a by lubricant pipe and joint.The oil outlet of filter 3a and the oil inlet P mouth of 3-position 4-way solenoid directional control valve 2 are joined.The A of solenoid directional control valve 2, B oil outlet link together with 2 lubricating point 7a, 7b of concrete piston respectively.The oil return inlet T of solenoid directional control valve 2 and the return opening of lubricant pump 6 join.Concrete control can manually or automatically be operated.
Manually lubricated promptly before the start pumping, after shutting down and shutdown when to be expected, grease pump supplies fat for each lubricating point.Press the manual profit button on the electric control cubicle, this moment, the circuit of electronic grease pump 1 was connected, and grease pump is started working.Oil outlet 5a, 5b go out fat simultaneously.The 5a oil outlet is by drier oil filter 3b, 6 point type progressive distributors.Can to stirring shaft bearing support, " S " manage big small bearing bracket, and each lubricating point of pendulum valve oil cylinder bearing be lubricated.Until all having seborrhea to go out to get final product everywhere.The 5b oil outlet enters 3-position 4-way solenoid directional control valve 2 by drier oil filter 3a.Selector valve (DT1 gets) grease when position, a left side advances the A mouth from the P mouth and goes out this moment lubricating point 7b to be lubricated.Selector valve (DT2 gets) grease when right position advances the B mouth from the P mouth and goes out (concrete piston can run to terminal point with piston by inching button) this moment lubricating point 7a to be lubricated.Selector valve when concrete piston need not lubricate when meta (DT1, DT2 be dead electricity simultaneously) grease advance the T mouth from the P mouth and go out the return opening 6 that enters grease pump by lubrication management.
Self oiling promptly is lubricated in the concrete pumping working procedure.Press the automatic profit button on the electric control cubicle, this moment, the circuit of electronic grease pump 1 was connected, and grease pump is started working.Oil outlet 5a, 5b go out fat simultaneously.The 5a oil outlet is by filter 3b, 6 point type progressive distributors.Can to stirring shaft bearing support, " S " manage big small bearing bracket, and pendulum valve oil cylinder bearing to carry out the edge work limit lubricated.The 5b oil outlet enters 3-position 4-way solenoid directional control valve 2 by filter 3a.Selector valve a when position left side (DT1 get electric and left cylinder commutation simultaneously) grease advance the A mouth from the P mouth and go out at this moment lubricating point 7b to be lubricated.Selector valve (DT2 get electric and right cylinder commutation simultaneously) grease when right position advances the B mouth from the P mouth and goes out (concrete piston can run to terminal point with piston by inching button) and at this moment lubricating point 7a is lubricated.Selector valve when concrete piston need not lubricate when meta (DT1, DT2 be dead electricity simultaneously) grease advance the T mouth from the P mouth and go out the return opening 6 that enters grease pump by lubrication management.
In sum, the utility model can inject the lubricating point injection grease of lubricant grease to needs, lubrication pressure grease this moment is except providing lubricated to piston, the moment negative pressure of also resisting the concrete material generation simultaneously prevents that concrete is to wearing for piston, and to temporarily not needing the lubricating point of lubricant grease not supply lubricant grease, reach the working life of having improved piston and transmission and concrete transmission cylinder, saved the lubricating grease consumption, reduce that lubricant grease injects water tank and the waste that causes lubricant grease.Avoided effectively simultaneously prior art 02277346.0 patent existing complex structure, cost height, be difficult for problems such as accurately control and waste grease.
