Described fuel tank 4 is arranged on fuel tank placement platform 28, higher than the first oil hydraulic cylinder 5 and the second oil hydraulic cylinder 6 at the bottom of the case of fuel tank 4, the lubricant oil in fuel tank 4 can be made like this to move to the first oil hydraulic cylinder 5 and the second oil hydraulic cylinder 6 under the effect of deadweight, energy spent when saving the first oil hydraulic cylinder 5 and the second oil hydraulic cylinder 6 oil suction.
Arranging of first oil-absorbing pipeline 9, second oil-absorbing pipeline 10 and point oily three-way valve 11 can simplified structure, reduces the quantity of parts and saves the length needing the oil-absorbing pipeline used, reducing costs.
Have toothed portion and the Locking arc part of three-way valve, one-way valve, the first link 32, second link 33, power input pad 31, partial gear all belong to related domain routine techniques, and its concrete structure no longer describes in detail.
During work, as shown in Figure 3, locking bar 3 drives power to input tooth bar 23 by power connecting rod 30 and power input pad 31 and moves to the left shown in arrow in Fig. 3, drive power input gear 17 to be rotated counterclockwise.Power input gear 17 drives initiatively partial gear 18 to be rotated counterclockwise by driving shaft 14.Because the circumferential length of power input gear 17 is equal with the length that power inputs the single direction stroke of tooth bar 23, therefore in a single direction stroke, driving shaft 14 just in time rotates a circle, and becomes one-period.
Initiatively partial gear 18 is before rotation in 1/4th cycles, it has toothed portion A to drive the first driven partial gear 19 to turn clockwise, and (meanwhile initiatively the Locking arc part B of the partial gear 18 and Locking arc part B of the second driven partial gear 21 is combined together, under the locking effect of Locking arc, second driven partial gear 21 can not rotate), first driven partial gear 19 drives the first coaxial power output gear 20 to turn clockwise, first power output gear 20 drives the first Power output tooth bar 24 to the right motion shown in Fig. 3, the piston rod that first Power output tooth bar 24 promotes the first oil hydraulic cylinder 5 moves right, thus make the first oil hydraulic cylinder 5 oil spout.During the first oil hydraulic cylinder 5 oil spout, the first oil sucting one-way valve 39 is closed, and prevents lubricant oil from passing through a point oily three-way valve and sprays into fuel tank 4 11 times.Initiatively partial gear 18 is in rear 3/4ths cycles of rotating, initiatively the Locking arc part B of the partial gear 18 and Locking arc part B of the first driven partial gear 19 is combined together, under the locking effect of Locking arc, first driven partial gear 19 can not rotate, simultaneously, from then on 3/4ths cycles at the beginning, and the first oil spout pipeline 7 closed by the first oil spout one-way valve 37.
Lubricant oil is sprayed onto the secondary root of external locking mechanism friction by the first oil-absorbing pipeline 9, first oil spout three-way valve 12 and the first oil spout pipeline 7 by the first oil hydraulic cylinder 5 successively, lubricant oil is progressively launched by friction pair in the friction stroke of follow-up 3/4ths, thus raising lubrication effect, and save the use amount of lubricant oil compared with lubricating oil spraying equal in whole single direction stroke.
Initiatively partial gear 18 is in rear 1/4th cycles of rotating, it has toothed portion A to drive the second driven partial gear 21 to turn clockwise, second driven partial gear 21 drives the second coaxial power output gear 22 to turn clockwise, second power output gear 22 drives the second Power output tooth bar 25 to the right motion shown in Fig. 3, the piston rod that second Power output tooth bar 25 promotes the second oil hydraulic cylinder 6 moves right, thus makes the second oil hydraulic cylinder 6 oil suction.During the second oil hydraulic cylinder 6 oil suction, the second oil spout pipeline 8 closed by the second oil spout one-way valve 38.
Like this, in one-period (single direction stroke of locking bar 3), achieve the first oil hydraulic cylinder 5 oil spout and the second oil hydraulic cylinder 6 oil suction two actions, and two actions all complete within 1/4th cycles, need not all carry out oil spout or oil suction action within the time in whole cycle.
When entering next contrary unidirectional movement cycle after the unidirectional movement end cycle of moving direction shown in arrow in figure 3, power input tooth bar 23 is to the opposite direction shown in arrow in Fig. 3 and right motion, in front 1/4th cycles of this cycle of motion, the second power output gear 22 drives the second oil hydraulic cylinder 6 to complete oil spout action, and in rear 1/4th cycles, the first power output gear 20 drives the first oil hydraulic cylinder 5 to complete oil suction action.
Locate each locking mechanism due to same track switch and all need lubrication, therefore each locking mechanism place all needs to install lubricating structure, and often locates lubricating structure at a distance of nearer.Adopt the present invention, then these can share a fuel tank 4 at a distance of nearer lubricating structure, and that fuel tank 4 can be designed is comparatively large, not only facilitates and refuels and observe, can also reduce refueling times, save human resources.
Fuel tank 4 shown in Fig. 1 is the shared fuel tank 4 of each lubricating structure (only providing place's lubricating structure in Fig. 1), can be distributed to inside each oil hydraulic cylinder by lubricant oil by setting up a point oily three-way valve.Fuel tank 4 is placed on the fuel tank placement platform 28 of about 0.5 meter high, and such lubricant oil can be sucked into oil hydraulic cylinder easily under the effect of deadweight.
