Embodiment:
Referring to Fig. 1-7, multi-way valve operation mechanism for fork lift comprises multiway valve 7, and described multiway valve 7 is located on the fork truck car body by multiway valve support 18.Also comprise rectangular frame cribbing 6, rectangular frame cribbing 6 is being connected hinge frame 3 with multiway valve 7 corresponding end by axle 11, the cross-sectional plane of hinge frame 3 is the angle steel shape, the horizontal side of hinge frame 3 is flexibly connecting two piston rods 2 by short pin 15 respectively, two piston rods 2 are respectively anteversion and retroversion piston rod and lifting piston connecting rod, the vertical side edge of hinge frame 3 is shipped and resell on another market by two respectively and 12 is being connected two connecting rods 4 respectively, the other end of two connecting rods 4 is connecting anteversion and retroversion joystick 10 and lift control lever 5 by connecting rod pin 13 respectively, anteversion and retroversion joystick 10 and lift control lever 5 be by control lever shaft 14 coaxial rectangular frame cribbing 6 middle parts that are installed in, and control lever shaft 14 and axle 11 are in the isoplanar and parallel; The other end of rectangular frame cribbing 6 is equipped with the attaching parts 8 of locking;
Rectangular frame cribbing 6 both sides are connecting multiway valve support 18 by bearing pin 17 respectively, and bearing pin 17 and axle 14, axle 11 are in the isoplanar and parallel.
Distance between above-mentioned control lever shaft 14 and the axle 11 is the 100-150 millimeter.
Be arranged with spring 9 on the above-mentioned rectangular frame cribbing 6 one side bearing pins 17, spring 9 one ends are fixed on the rectangular frame cribbing 6, and the other end is fixed on multiway valve support 18 outsides.
The length of above-mentioned anteversion and retroversion joystick 10 and lift control lever 5 is respectively the 200-250 millimeter.
Spacing between above-mentioned axle 11 and the bearing pin 15, spools 11 and the spacing between 12 of shipping and reselling on another market, control lever shaft 14 all equate with spacing between the connecting rod pin 13.
Multi-way valve operation mechanism for fork lift has two degree of freedom, realizes two kinds of motions, sees Fig. 1 and Fig. 2, be that F1 realizes that multiway valve spool up-and-down movement is to finish loading and unloading, F2 realizes that support rotatablely moves around the e point, i.e. the upset of the mechanism of realization own is seen Fig. 1 and Fig. 2 to dodge digging of battery box cover.Introduce the principle of work of multiway valve steering unit below: this mechanism has 6 members, and 7 hinges move by a narrow margin with 1 by a narrow margin, so its degree of freedom F=3n-2PL-PH=3x6-2x8-0=2.Illustrate respectively by two degree of freedom how member is realized moving below.At first be the up-and-down movement (F1 driving) that will realize part spool 1, this moment, rectangular frame cribbing 6 was lock constructions of fixing for the fork truck model.F1 puts on anteversion and retroversion joystick 10 or lift control lever 5, and anteversion and retroversion joystick 10 or lift control lever 5 and hinge frame 3 are done the equal angles rotation around a and 2 of d respectively, so the f point rotates around d, make spool 1 up-and-down movement by piston rod 2.Rectangular frame cribbing 6 rotates certainly because hinge frame 3, connecting rod 4, anteversion and retroversion joystick 10 or lift control lever 5 hinges are tied in rectangular frame cribbing 6 around the e point, also can rotate around the e point with rectangular frame cribbing 6, applies F2 on support, and it is rotated around e.In order to guarantee that steering unit piston rod 2 when e overturns can not have up-and-down movement, promptly guarantee when upset, hinge frame 3, connecting rod 4, anteversion and retroversion joystick 10 or lift control lever 5 are relative static with rectangular frame cribbing 6, so when design, just must allow valve handle structure part piston rod 2 overlap at initial position with hinge e with the hinge f of hinge frame 3, and the axial line that requires control lever shaft 14 in the mechanism, bearing pin 17 and axle 11 is in same plane, be a, d, 3 of e are in same plane, dc=de=ab, cd//ab.
Fig. 6, Fig. 7 medi-spring 9 one ends are fixed on the rectangular frame cribbing 6, and the other end is fixed on multiway valve 7 outside multiway valve supports 18, and are rotatable around hinge e.Because multiway valve 7 is Immobile, rectangular frame cribbing 6 will be realized upset around the e hinge under the effect of spring force, is turned to 89 spacing when spending as required at it.Need to prove that at this moment the F1 degree of freedom does not have other addition of constraints, but overcome joystick gravity, can not make spool 1 that downward motion is arranged by part multichannel spool 1 contained spring power.And when the needs return, under the effect of manpower, by the lock construction auto lock, can handle multiway valve valve core movement mechanism this moment to the position of setting.
