Further scheme is installed with Rubber shock-absorbing pad 7 between lower sheave group 5 and track 6.
Since subject hydraulic oil container 11 is welded on fuel tank mounting bracket 10, fuel tank mounting bracket 10 is mounted by means of bolts on
It rolls on trolley 8.Fuel tank mounting bracket 10 and roll angle (A, B both direction in Fig. 1 that 45 degree of adjustment can be controlled between trolley 8
Respectively 45 degree angles of adjustment), operating mode during for simulating vehicle respectively to left sharp turn and sharp right-hand bend is illustrated in figure 4 to A turns
45 ° of simulation vehicles are illustrated in figure 5 to B to left sharp turn and turn 45 ° of simulation vehicle sharp right-hand bends.
1st, the present apparatus can simulate hydraulic oil in subject hydraulic oil container in the real motion situation brought to a halt, specifically
It is as follows：
When compressed gas enters the rodless cavity of cylinder 13 from the air admission hole of rodless cavity, cylinder rod 13.1 will be pushed out,
Cylinder rod drives lifting hook device 12 to be moved to the direction for rolling trolley 8.Drag hook 12.2 is connected to fixed plate by shaft 12.4
12.5 top, drag hook 12.2 can be rotated freely around shaft 12.4.Due to the left side ratio right side weight of drag hook 12.2, so drawing
The trend rotated counterclockwise around shaft 12.4 is carved with during hook.Limited post 12.3 is mounted on by thread forms on drag hook 12.2,
It can arbitrarily be adjusted by rotary stopper column 12.3 and stretch out the length (length of H in such as Fig. 2) of 12.2 bottom of drag hook, so as to
It can ensure parallel with track 6 at the time of the upper plane of drag hook 12.2.
When cylinder 13 reaches range, drag hook 12.2 is contacted with positioned at the stay hook 12.1 for rolling 8 rear end of trolley, and
Automatically into the inside of stay hook 12.1 under the action of arc-shaped transition plate 12.6 on the right side of it, and in drag hook 12.2 from recast
Reach again under parallel with track 6.When cylinder 13 carries out next action, when compressed gas enters the rod chamber of cylinder 13,
Drag hook 12.2 will pull roll trolley 8 move right, then roll trolley 8 drive rope 9 will fall rack 3 and fall object 4 together with draw
It rises, the height being pulled up is equal to the stroke of cylinder 13.
When cylinder rod 13.1 is withdrawn and approaches the tripping gear 15 being fixed on cylinder casing wall, the right end circle of drag hook 12.2
Block 12.7 will be contacted with unhook baffle 15.2, since unhook baffle 15.2 and track 6 have certain angle, can force drag hook
12.2 12.4 are rotated clockwise around the shaft, and the left side so as to cause drag hook 12.2 is lifted, and when lifting to a certain extent, are drawn
Hook 12.2 departs from stay hook 12.1, that is, rolls trolley 8 and depart from cylinder 13, fast under the gravity of pendant rack 3 and pendant object 4
Speed declines, and passes through rope 9 and pull rolling trolley 8, makes subject hydraulic oil container 11 that the left side to track 6 be accelerated to move, and final
Fiercely bump against with Rubber shock-absorbing pad 7 and stop rapidly, complete a test cycle at this time.
Then compressed air repeats in the case where solenoid directional control valve adds pulse signal control or under PLC controls, discontinuously enters gas
The rodless cavity and rod chamber of cylinder, so as to act more than repeating, subject hydraulic oil container 11 is with rolling the shock rubber of trolley 8 again
Glue beam 7 so as to simulate the hydraulic oil in subject hydraulic oil container 11 in the real motion situation brought to a halt, and is examined
Survey the sealing performance of each parts in subject hydraulic oil container 11.
Ibid, when along A, B both direction, respectively 45 degree of adjustment carries out bump tests between fuel tank mounting bracket 10 and rolling trolley 8
When, the motion conditions of fork truck hydraulic oil in hydraulic oil container in the case of the left and right zig zag can be simulated respectively.
2nd, this experimental rig be also emptied with hydraulic oil moment, moment oil return and heating function, for simulating fork truck in height
Fast lifting under warm oil, hurtle down action.As shown in Figure 3：
Before being tested, it is tested in hydraulic oil container 11 and heating fuel tank 17 and all fills hydraulic oil, while heating fuel tank 17
Interior hydraulic oil is heated by heater 16, and is maintained at the temperature of setting.When testing progress, motor 21 drives oil pump 20
Start, oil can be entered by the A mouths of fuel sucking pipe into the first two-position three way magnetic valve 18.1 by being tested the hydraulic oil of hydraulic oil container 11
Then the oil inlet C of pump 20 enters the G mouths of the second two-position three way magnetic valve 18.2, then from it by the oil outlet D of oil pump 20
H mouthfuls out enter in heating fuel tank 17.This action will simulate the fork truck situation that hydraulic oil is emptied by moment under raising operating mode.
The power source of first two-position three way magnetic valve 18.1 and the second two-position three way magnetic valve 18.2 is in intermediate relay
22, intermediate relay 22 plays provides alternate working power signal for two solenoid valves.When 22 alternate change of intermediate relay
During the power supply of two solenoid valves, the first two-position three way magnetic valve 18.1 and the second two-position three way magnetic valve 18.2 commutate simultaneously, this
When, hydraulic oil will enter oil pump 20 by the B mouths of the fuel sucking pipe of heating fuel tank 17 into the first two-position three way magnetic valve 18.1
Oil inlet C, then from D mouthfuls of oil pump out after enter the G mouths of the second two-position three way magnetic valve 18.2, finally come out from its I mouthfuls
After return to subject hydraulic oil container 11 in.The operating mode of fuel tank moment oil return is tested so as to simulate fork truck in lowering action.
Keep each oil suction identical with the amount of oil return under the control of intermediate relay 22 simultaneously and less than subject hydraulic oil
The volume of case 11.Oil suction each time and oil return are a test cycle, and the high temperature oil after each Xun Huan in heating fuel tank 17 will
It is tested by injection in hydraulic oil container 11, it is identical so as to reach oil temperature in whole system.In addition overflow is added in this hydraulic circuit
Valve 19 when the first two-position three way magnetic valve 18.1 and asynchronous the second two-position three way magnetic valve 18.2 appearance commutation, will make
System pressure is excessive in this oil circuit, and when pressure is excessive in system, hydraulic oil can return to heating oil by the E-F mouths of overflow valve 19
In case 17, that is to say, that overflow valve 19 plays system pressure protective effect.When cycling according further to total time on test and every time
Between it is estimated that total test number (TN), according to above action can investigate hydraulic oil container assembly and parts in forklift lifting and
Whereabouts operating mode seal performance energy.
Above example is not limited only to protection scope of the present invention, all to be repaiied based on basic thoughts of the invention
Change or what is changed belongs to protection scope of the present invention.
