Abstract
The invention provides a viscous grease plectrum plate delivery mechanism in an oil tank. The structural principle is that one side of a hinge is fixedly connected in a lubrication oil tank, and the other side of the hinge is fixedly connected with a plectrum plate; a hinge shaft is enwound by a recovery spring; the upper end of an oil cylinder is connected with a main oil path through a duct; the oil cylinder body is fixed in the lubrication oil tank; a piston rod end which is extended out of the lower end of the oil cylinder is connected with a steel wire which is connected with the plectrum plate by the other end after passing through a guide hole along the axis direction close to the piston rod. Every time when the oil pump is in use, the oil pressure in the main oil path pushes the piston rod of the oil cylinder to stretch; the plectrum plate is pulled by the steel wire to rotate around the hinge shaft, and the grease which is in the oil tank and far away from the oil suction of a gear pump is delivered to the oil suction, which is convenient for pumping. Therefore, the medium range used for concentrated lubrication can be enlarged to viscous grease, then the lubrication effect can be improved, the grease can be saved, meanwhile, the invention effectively avoids that the grease is settled at the bottom of the oil tank for a long time and goes bad due to being not pumped.
Description
(1) technical field
The present invention relates to the grease lubrication technical field, relate in particular to a kind of vehicle centralized lubrication viscous grease dialing plate conveyer in fuel tank.
(2) background technique
The grease centralized lubrication system that adopts on the present vehicle, the gear pump at the bottom of adopting the rectangular cross-section fuel tank more and going deep into case etc. constitutes for the fatty oil pump.For example German good fortune bird KFU2-40, its fuel tank cross section is much larger than the gear pump inlet port, when using the higher grease of stickiness, because thickness grease flowability is very poor, the grease far away apart from the gear pump inlet port can not flow to the gear pump inlet port automatically and carry out repairing, and cause that oil pump supplies bad phenomenon such as fat deficiency, grease emulsifying and extraordinary noise, does medium so can only use rarer grease.And use the existing raising lubrication effect that is beneficial to of thickness grease, and save grease again, therefore, be necessary to develop the auxiliary Oil sucking device of a kind of gear pump, be beneficial to the thickness grease in the smooth pumping of centralized lubrication fuel tank.
(3) summary of the invention
The objective of the invention is to, take structural measure, the auxiliary gear pump oil suction provides a kind of viscous grease dialing plate conveyer in fuel tank that is used for vehicle and machinery centralized lubrication system.
The technical solution used in the present invention: a side of a hinge is fixedly connected in the lubricating oil tank, and fixedly connected group of plate of hinge opposite side is wound with return spring on the hinge hinge axis.An oil cylinder upper end connects main oil gallery by conduit, and cylinder body is fixed in the lubricating oil tank, and the piston rod end that stretch out the oil cylinder lower end connects a steel wire backguy, and the other end was bound up on group plate after guide hole was passed near piston rod axis direction in steel wire backguy edge.Each when oil pump is worked, the main oil gallery oil pressure promotes the piston rod elongation of oil cylinder, dials the hinge axis that plate wraps page or leaf by steel wire backguy pulling, and grease far away apart from the gear pump inlet port in the fuel tank is delivered to inlet port.After oil pump quits work, main oil gallery release, piston rod and dial plate return under return spring effect separately.
The present invention can reach following good effect: dial plate conveying grease owing to adopted oil cylinder to drive, make the interior thickness grease far away of fuel tank also can be pumped apart from the gear pump inlet port, so can be the expanded range of centralized lubrication used medium to grease than thickness, improve lubrication effect, save grease, the while is effectively avoided the long-term deposition of fuel tank bottom grease not to be pumped and goes bad.
(4) description of drawings
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is the part of Fig. 1 embodiment's plan view.
(5) embodiment
As shown in Figure 1, fix a support 2 on the valve body 1, support 2 is fixedlyed connected with hinge 4 left sides after extending to fuel tank 3 sidewalls; The fixedly connected group of plate 5 in hinge 4 right sides is wound with return spring 6 on the hinge axis of hinge 4; The main oil gallery that conduit 8 connects valve bodies 1 is passed through in oil cylinder 7 upper ends, and the lower end is fixed on support 2 the other ends with nut 9; Connect a steel wire backguy 11 in piston rod 10 end hole that stretch out oil cylinder 7 lower ends, steel wire backguy 11 is bound up on group plate 5 along pass the guide hole 12 back the other ends near piston rod 10 axial directions.
Figure 2 shows that when piston rod 10 is flexible, dial the inswept area of plate 5.
The present invention is not limited to above-mentioned arrangement, and the hinge axis of hinge also can lie low at the bottom of fuel tank with group plate that is connected, and dials plate during work around upwards inwardly upset of hinge axis; Perhaps hinge one side is fixed under the fuel tank cap, and the hinge axis of hinge can level place fuel tank interior than the upper part, dials plate during work around hinge axis inwardly upset downwards.Can make some little slotted hole and small sircle holes on the of the present invention group of plate.Piston rod end of the present invention can be provided with a pulley structure, and the steel wire backguy ties up on the support after passing the piston rod end pulley, forms pulley structure.
