In Fig. 4, it is the yoke group constructional drawing of an A both arms connection and a B both arms joint group synthesis.Two yoke connection combined crosswise, the yoke having another yoke to join in the middle of each yoke di-yoke.A yoke group has four yokes.

In Fig. 5, be jacking system and propelling unit constructional drawing.Simultaneously referring to the spatial structure in Fig. 1.

In Fig. 6, it is the birds-eye view of Fig. 5.Contrast Fig. 5 and Fig. 6 observes.In order to observe conveniently, in Fig. 6, take down the support 14 that hanger 11 in Fig. 5 is connected with on propelling cylinder 23 and with vertical balladeur train 16.

One in two yoke connection of a yoke group can only be seen in Fig. 5.Vertical balladeur train 16 is connected as a single entity with level and smooth frame 21 and mutually vertical.Have notch in the middle of vertical balladeur train 16, notch both sides are slideways, are provided with vertical slide block 17 in slideway.The fork handle 18 of yoke group 20 is from the right through the notch in the middle of vertical balladeur train, and vertical slide block 17 lower end is fixed on above the termination of fork handle 18 through the vertical balladeur train left side.The upper end of hoist cylinder 15 is fixed on the support 14 that is connected with vertical balladeur train 16.Piston rod 32 lower end of hoist cylinder be connected to be fixed on vertical slide block lower end support 14 on.Propelling cylinder 23 is connected on fork handle 18 termination, and support 14 has anchor ear to fix propelling cylinder 23, in order to avoid beat.Piston rod 32 termination of propelling cylinder 23 is fixed with slide plate 35, is arranged in the respective slide slots of pushing plate 25.While hoist cylinder drives vertical slide block that fork handle is elevated, propelling cylinder 23 is also driven to move up and down.The piston rod 32 of propelling cylinder 23 is also along with moving up and down, and the slide plate 35 of its termination just slides up and down in the chute of pushing plate 25.Level and smooth frame 21 there is slide block, is arranged in the chute of propelling slide plate 24.Propelling cylinder 23 makes piston rod extend and shortens, but piston rod end is fixed in the chute of pushing plate by slide plate 35, can not sway, so can only make the sway of propelling cylinder own, namely drives fork handle and yoke group advance or retreat.

Each yoke connection of a yoke group has independently jacking system and a propelling unit.As in Fig. 6, can find out that two yoke connection 36 of a yoke group respectively have a vertical balladeur train, vertical slide block, hoist cylinder and level and smooth frame, propelling cylinder, a propelling slide plate.The yoke connection drawn in Fig. 6 is a single armed connection, and namely a yoke connection only has a yoke.

Fig. 7, Fig. 8, Fig. 9 are principle of work instruction diagrams.Here carry out describing with in two yoke groups.Each yoke group is joined to become with a B both arms joint group by A both arms, totally four yokes.Do not draw the fork handle of each yoke connection, jacking system and propelling unit in Fig. 7, Fig. 8, Fig. 9, only depict yoke part and how to inject below goods, how co-operatively to rise, decline, the process such as advance.Convenient in order to describe, four yokes from bottom to top by 1,2,3,4 numberings.1, No. 3 is A yoke connection, and 2, No. 4 is B yoke connection.To pitch dress carrying casing type objects.

In Fig. 7, K-K vertical line is the initial that four yokes start to insert below casing.1, No. 3 yoke of 1, A yoke connection is motionless in initial position, and 2, No. 4 yokes of B yoke connection advance, and the interdigital wedge mouth in yoke front end injects institute and pitch the gap of lifting between casing and following object, and reeve a bit.Then these two interdigital on forward to and yoke flush position, pry open expand some gaps, keep motionless.Every yoke in advance, interdigital all oblique below.In 2, Fig. 8, the interdigital oblique below of 1, No. 3 yoke, advances at once, and interdigital front end wedge mouth inserts by the gap pried open, inserts darker.Then forward to and yoke flush position on interdigital, yoke is lifted suitable height, keep motionless.In 3, Fig. 9,2, No. 4 yokes interdigital under forward oblique below to.Then, 2, No. 4 yokes advance certain distance at once, and forward on interdigital and yoke flush position, whole yoke front is inserted below casing, and lift a bit suitably, lift at the bottom of case, reserving 1, No. 3 yoke has the space that suitably declines, and keeps motionless.Following process is, often organizes interdigital corresponding lower turn of yoke and above to turn, yoke alternately decline a bit to setting height, proceed to setpoint distance, rise to setting height and lift casing, until inserted through below whole casing.I.e. liftable tote box body.Yoke injects below casing and does not rub to below casing in process.

During unloading, casing is lifted and transports to suitable height above put position, the bigeminy yoke of each yoke group is alternately lifted casing, alternately declines, is retreated, until casing puts off placement location.

Often joining the rising of yoke, declining is that the jacking system that connected by fork handle completes.Often joining the advance of yoke, retrogressing, is that the propelling unit connected by fork handle completes.

Insert at first in the following a small amount of gap of casing at yoke and start one to three time, available Non-follow control operation, press autokeyer later, yoke inserts the overall process below whole casing, all controls hoist cylinder, propelling cylinder and small oil tank by autonomous cruise speed system follow procedure and controls the whole cycle event of yoke.Yoke group, inserted through stroke needed for goods, has just been twisted the turn-knob of yoke propelling stroke control panel before automatically controlling to start by operator.Yoke one completes this stroke, at once can automatically stop advancing.Lift goods later, transport goods, operate with Non-follow control.During unloading, goods is lifted to suitable height above rest area, presses autokeyer, yoke and automatic back alternately, until all exit below casing.

Fork is pretended when soft object, selects the yoke group of the six roots of sensation or eight yoke compositions, to expand area of thrust surface and field of load.

In Figure 10, be that yoke is not with interdigital constructional drawing.The yoke of composition yoke connection has to be with interdigital and not to be with interdigital two kinds of structures.Do not become wedge-like with interdigital yoke front end, pitch load limit do not have pallet fork to insert the goods in space time, first insert with the yoke front end wedge mouth of each yoke connection in two yoke groups and to be handled upside down between object and following object in gap.Yoke is lifted a bit, pry open and expand some gaps.This object is injected at once below by the gap that levers up in the yoke front end of another yoke connection.Alternately lever up, inject, it is following that whole yoke front end is all inserted into object.So latter two yoke connection alternately rising lift object motionless, decline, advance, rise, identical with above-mentioned principle of work, until following inserted through object, i.e. liftable carry an object.During unloading, goods is lifted and is transported to above placement location, and two yoke connection of each yoke group replace rising and lift goods, decline, retreat, until goods puts off in rest area.

In Figure 11, be that combination yoke light roadster carries out fork dress bag cargo handling situations figure.Be that directly top fork carries away several bags from the bag cargo of pile, 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 midway location of two yoke groups below vehicle frame 28, supports on the ground.Then, the fork dress of goods 37 is carried out.

In Figure 12, be that after fork loading thing, yoke group is placed on situation map when vehicle frame is walked.Principal arm, swing arm all shrink and shorten, and two groups of propulsive unitses of yoke group are placed on the both sides of rotating disk.Vehicle body entire length reduces, and center of gravity reduces, and go-cart walking is safer, convenient.

Insert under goods in crack approach at yoke, if propelling cylinder interval alternately advances fork handle to drive yoke to advance, until following inserted through goods.If vehicle body itself is motionless, so just cause and advance slide plate long, propelling cylinder is also long.Therefore can by two kinds of structure manufactures.One advances Lengthened slide plate type, and one advances slide plate coventional type.Extended type advances slide plate to be namely lengthen to advance slide plate, propelling cylinder peace balladeur train, and can disposablely provide yoke inserted through the following advance distance of goods, vehicle body is motionless.The propelling unit that this light roadster is installed and yoke total length, shorter than existing fork truck total length.Because fork dress bag cargo and casing class, combination yoke itself is not long.Another kind of structure advances slide plate coventional type, advances slide plate not lengthen.When advancing slide plate and propelling cylinder stroke to run low, send signal, operating personal go-cart is advanced a segment distance, and yoke is motionless.Vehicle body makes the oil pipe on propelling cylinder inner carrier both sides all communicate with oil extraction case before advancing, namely identical with barometric pressure.Vehicle body enters oil extraction case by pushing plate push piston bar the oil of right for oil cylinder section in advancing.Drop on following goods under yoke or ground, on yoke, the weight of goods is pressed on yoke, and the resistance that yoke advances is very large, can not advance.Level and smooth frame is inherently very little with the friction drag of propelling slide plate, so only have level and smooth frame to slide.So when vehicle body advances, yoke is motionless.Yoke repeatedly intermittent leaves this segment distance of pushing plate and is eliminated in advancing.Yoke can restart to advance.Vehicle body moves propelling 1 to 2 time just.This structure, can reduce the length of propelling unit.
