Each yoke connection of one yoke group has independent a lowering or hoisting gear and propulsion plant., can be with as in Fig. 6 Finding out two yokes connection 36 of a yoke group respectively has a vertical balladeur train, vertical sliding block, hoist cylinder and smooth frame, a propulsion oil Cylinder, propulsion slide plate.The yoke connection drawn in Fig. 6 is a single armed connection, i.e., one yoke connection only has a yoke.

Fig. 7, Fig. 8, Fig. 9 are operation principle explanation figures.Here described with one in two yoke groups.Each fork Arm group is all into totally four yokes by A both arms connection and a B both arms joint group.Each yoke connection is not drawn into Fig. 7, Fig. 8, Fig. 9 Fork handle, lowering or hoisting gear and propulsion plant, only depict how yoke part is injected below goods, how to cooperate on the ground The processes such as liter, decline, advance.In order to describe conveniently, four yokes from bottom to top by 1,2,3,4 numberings.1st, No. 3 are A yokes Connection, 2, No. 4 be B yokes connection.Exemplified by pitching dress and carry casing type objects.

In Fig. 7, K-K vertical lines are the initials that four yokes are initially inserted into below casing.1, A yoke connection 1, No. 3 forks Line position is motionless starting for arm, B yokes connection 2, No. 4 yokes advance, yoke front end interdigital wedge mouthful inject pitch lift casing and Gap between following object, is injected a bit.Then this two it is interdigital on go to yoke flush position, pry open expansion some seam Gap, is remained stationary as.Every yoke is in advance, interdigital all oblique lower section.In 2, Fig. 8,1, the interdigital oblique lower section of No. 3 yokes, Advance at once, it is more extending deeper in the gap that interdigital front end wedge mouthful insertion is pried open.Then gone on interdigital concordant with yoke Appropriate height is lifted on position, yoke, is remained stationary as.In 3, Fig. 9,2, No. 4 yokes it is interdigital under go to oblique lower section.Then, 2,4 Number yoke horse back advance certain distance, it is interdigital on go to yoke flush position, in front of whole yoke below insertion casing, suitably Upper lift a bit, lifts bottom, reserve 1, No. 3 yokes have it is appropriate decline space, remain stationary as.Procedure below is, every group of yoke Interdigital corresponding lower turn and it is upper turn, yoke alternately decline a little to setting height, proceed to setpoint distance, rise to setting height and lift Firmly casing, until being inserted through below whole casing.I.e. liftable tote box body.Yoke is injected during casing lower section to below casing Do not rub.

During unloading, appropriate height above put position is transported in casing lift, the bigeminy yoke of each yoke group is alternately lifted Casing, alternately decline, retrogressing, until casing puts off placement location.

Often rising, the decline of connection yoke is that the lowering or hoisting gear connected by fork handle is completed.Often connection yoke advance, after Move back, be that the propulsion plant connected by fork handle is completed.

Insert and start one to three time in the following a small amount of gap of casing at first in yoke, manual control operation can be used, pressed later Lower autokeyer, the overall process that yoke is inserted below whole casing, all by automatic control system by programme-control hoist cylinder, Propelling cylinder and the whole do actions of small oil tank control yoke.Yoke group is inserted through the required stroke of goods, by operator automatic Control has just twisted the turn-knob that yoke promotes Stroke Control disk before starting.Yoke one completes this stroke, can be automatically stopped at once Promote.Lift goods later, transport goods, using manual control operation.During unloading, goods is lifted to appropriate high above rest area Degree, presses autokeyer, yoke is automatic back alternately, until all exiting below casing.

Fork is when filling relatively soft object, from the six roots of sensation or the yoke group of eight yoke compositions, with expand lifting surface area and by Power scope.

It is yoke without interdigital structure chart in Figure 10.The yoke of composition yoke connection has with interdigital and without interdigital two kinds Structure.Without interdigital yoke front end into wedge-like, when fork loads side and do not have the goods of pallet fork insertion space, first with two yokes The yoke front end wedge mouthful insertion of each yoke connection in group is handled upside down between object and following object in gap.One is lifted on yoke Point, pries open some gaps of expansion.The yoke front end of another yoke connection is injected in the gap that the object is levered up below at once.Hand over For levering up, injecting, it is following that whole yoke front end is all inserted into object.Right latter two yoke connection alternately rising lift object it is motionless, under Drop, advance, rising, it is identical with above-mentioned operation principle, it is following until being inserted through object, you can to lift carry an object.During unloading, goods Lift is transported to above placement location, and alternately goods is lifted in rising to two yokes connection of each yoke group, is declined, is retreated, until goods Put off in rest area.

It is that combination yoke light roadster carries out fork dress bag cargo handling situations figure in Figure 11.It is directly from the packed of pile Top fork carries away several bags in goods, and the situation map of the direct pile of another placement location can be transported to again.Before fork loading thing 37, Support 26 first reaches the centre position of two yoke groups from the lower section of vehicle frame 28, and support is on the ground.Then, goods 37 is carried out Fork dress.

It is to pitch yoke group after loading thing to be placed on situation map when walking on vehicle frame in Figure 12.Principal arm, swing arm, which all shrink, to shorten, Two groups of propulsive unitses of yoke group are placed on the both sides of rotating disk.Vehicle body entire length reduce, center of gravity reduction, stroller walking it is safer, It is convenient.

During yoke insertion goods is following, if propelling cylinder alternates propulsion, fork handle drives yoke to advance, It is following until being inserted through goods.If vehicle body is motionless in itself, thus cause propulsion slide plate it is long, propelling cylinder is also long.Cause This can be manufactured by two kinds of structures.One kind is to promote Lengthened slide plate type, and one kind is to promote slide plate plain edition.Extended type promotes slide plate It is to lengthen to promote the peaceful balladeur train of slide plate, propelling cylinder, yoke can be disposably provided and be inserted through the following advance distance of goods, Vehicle body is motionless.The propulsion plant and yoke total length installed on this light roadster, it is shorter than existing fork truck total length.Because fork pack Loading thing and casing class, combination yoke is not long in itself.Another structure is to promote slide plate plain edition, promotes slide plate not lengthen.When When propulsion slide plate and propelling cylinder stroke run low, signal, operating personnel's stroller one segment distance of advance are sent, and yoke is motionless. Before vehicle body advances, the oil pipe on propelling cylinder inner carrier both sides is all communicated with oil extraction case, i.e., it is identical with atmospheric pressure.During vehicle body advances The oil of right section of oil cylinder is discharged into by pushing plate push piston bar by oil extraction case.Dropped under yoke on following goods or ground, yoke The weight of upper goods is pressed on yoke, and the resistance that yoke advances is very big, it is impossible to advance.Frictional resistance of the smooth frame with promoting slide plate Inherently very little, so only smooth frame can be slided.So, when vehicle body advances, yoke is motionless.The multiple intermittent of yoke is promoted In leave pushing plate this segment distance and be eliminated.Yoke can restart to promote.Vehicle body movement promotes 1 to 2 time just.This knot Structure, it is possible to reduce the length of propulsion plant.
