Triple valve, check valve, the first connector 32, second connector 33, power input pad 31, partial gear
Toothed portion and Locking arc part belong to this area routine techniques, and its concrete structure is no longer described in detail.
During work, as shown in figure 3, locking bar 3 drives power defeated by power connector bar 30 and power input pad 31
Enter left movement of the rack 23 into Fig. 3 shown in arrow, drive the rotate counterclockwise of power input gear 17.Power input gear 17
The rotate counterclockwise of active partial gear 18 is driven by driving shaft 14.Due to the circumferential length and power of power input gear 17
The equal length of the single direction stroke of rack 23 is inputted, therefore in a single direction stroke, driving shaft 14 just rotates a circle, and turns into
A cycle.
Active partial gear 18 is in the preceding a quarter cycle of rotation, and its toothed portion A drivings first are driven endless
All gear 19 turns clockwise（At the same time driven partial gears of Locking arc part B and second of active partial gear 18
21 Locking arc part B is combined together, and under the locking effect of Locking arc, the second driven partial gear 21 will not rotate）,
First driven partial gear 19 drives the first coaxial power output gear 20 to turn clockwise, the first power output gear
Right of 20 the first power output racks 24 of driving shown in Fig. 3 is moved, and the first power output rack 24 promotes first hydraulic cylinder 5
Piston rod move right so that the oil spout of first hydraulic cylinder 5.During 5 oil spout of first hydraulic cylinder, the first oil sucting one-way valve 39 is closed
Close, prevent lubricating oil from passing through point oily 11 times penetrating fuel tanks 4 of triple valve.Latter 3/4ths weeks in rotation of active partial gear 18
Interim, the Locking arc part B of the driven partial gears 19 of the Locking arc part B of active partial gear 18 and first coordinates one
Rise, under the locking effect of Locking arc, the first driven partial gear 19 will not rotate, meanwhile, from this 3/4ths cycle one
Start, the first oil spout check valve 37 closes the first oil spout pipeline 7.
First hydraulic cylinder 5 passes sequentially through the first oil-absorbing pipeline 9, the first oil spout triple valve 12 and the first oil spout pipeline 7 will profit
Lubricating oil is sprayed onto the secondary root of external locking mechanism friction so that friction pair in follow-up 3/4ths friction stroke by lubricating oil by
Step expansion, so as to improve lubricant effect, and has saved compared with the equal lubricating oil spraying in whole single direction strokes the use of lubricating oil
Amount.
Active partial gear 18 is in the rear a quarter cycle of rotation, and its toothed portion A drivings second are driven endless
All gear 21 turns clockwise, and the second driven partial gear 21 drives the coaxial dextrorotation of the second power output gear 22
Turn, the second power output gear 22 drives right of the second power output rack 25 shown in Fig. 3 to move, the second power output tooth
Bar 25 promotes the piston rod of second hydraulic cylinder 6 to move right, so that the oil suction of second hydraulic cylinder 6.During 6 oil suction of second hydraulic cylinder,
Second oil spout check valve 38 closes the second oil spout pipeline 8.
So, in a cycle（The single direction stroke of locking bar 3）In, realize the oil spout of first hydraulic cylinder 5 and the second hydraulic pressure
6 oil suction of cylinder, two actions, and two actions completion within a quarter cycle, are all carried out without within the time of whole cycle
Oil spout or oil suction action.
Enter next opposite one-way movement cycle after the one-way movement end cycle of the direction of motion shown in arrow in figure 3
When, it is that right is moved that power, which inputs opposite direction of the rack 23 into Fig. 3 shown in arrow, the preceding a quarter of the period of motion
The second power output gear 22 driving second hydraulic cylinder 6 completes oil spout action, the first power in the rear a quarter cycle in cycle
The driving first hydraulic cylinder 5 of output gear 20 completes oil suction action.
Because each locking mechanism is required to be both needed to install lubricating machine at lubrication, therefore each locking mechanism at same track switch
Structure, and often place's lubricating structure is nearer apart.Using the present invention, then these can share a fuel tank at a distance of nearer lubricating structure
4, can design fuel tank 4 is more larger, not only facilitates and refuels and observe, can also reduce refueling times, saves human resources.
Fuel tank 4 shown in Fig. 1 is each lubricating structure（Lubricating structure at one is only provided in Fig. 1）Shared fuel tank 4, Ke Yitong
Cross and set up point an oily triple valve lubricating oil is distributed to inside each hydraulic cylinder.Fuel tank 4 is placed on about 0.5 meter of high fuel tank placement
On platform 28, such lubricating oil can easily be sucked into hydraulic cylinder in the presence of deadweight.
