Summary of the invention
A kind of dress of can pitching is the object of the present invention is to provide to carry the combination yoke not having pallet fork to insert the telescopic arm forklift of the goods in space below.
The present invention is achieved in that the combination yoke of telescopic arm forklift, and every root pallet fork is made up of several yokes, and the carrying of fork dress does not have pallet fork to insert the object in space below.The combination yoke of telescopic arm forklift is made up of yoke connection, yoke group, yoke connection jacking system, yoke connection propelling unit, pallet fork hanging block, control system.A yoke connection is made up of a fork handle and one to four yoke.Yoke connection jacking system by founding balladeur train, vertical slide block, hoist cylinder, fork handle form.Yoke connection propelling unit is made up of level and smooth frame, propelling slide plate, pushing plate, pallet fork hanging block, propelling cylinder.A yoke group is joined to combine by two yokes and forms, and the fork handle of each yoke connection is in same direction.A telescopic arm forklift installs two yoke groups.Pallet fork hanging block is arranged on the front door frame of telescopic arm forklift.Combine the both sides of propulsive units in the telescopic boom front end of telescopic arm forklift of yoke.The lifting of yoke connection, advance, retrogressing, come by control system control circuit and oil circuit.Pitch load limit do not have pallet fork to insert the goods in space time, each yoke group is first inserted in the gap between goods and following object that will carry with the yoke front end wedge mouth of yoke connection, yoke is lifted a bit, pry open and expand some gaps, this goods 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 inserted into goods, two yokes connection alternately rising to lift goods motionless, alternately decline, proceed to setpoint distance, rising, it is motionless to lift goods, alternately advance, until following inserted through goods, namely liftablely to transport goods.During unloading, goods is lifted and transports to above placement location, each yoke connection alternately rising is lifted goods, alternately declines, is retreated, and all exit goods following, namely goods puts off in rest area.Slide plate is advanced to have extended type and coventional type two kinds of structures.
Two yoke groups replace two pallet forks of telescopic arm forklift.Vertical balladeur train front is provided with camera.
Yoke is associated with single armed connection, both arms connection and multi-arm connection.The yoke be made up of a fork handle and yoke joins and makes single armed join.The yoke be made up of a fork handle and two yokes joins and makes both arms join.The yoke be made up of a fork handle and three or four yokes joins and makes multi-arm join.
Single armed connection is the socle of vertical welding " ┓ " shape fork handle in plane on a yoke rear end kept flat.Frame block direction above " ┓ " shape fork handle is contrary with yoke direction, and with yoke not at same plane, but its extended line is parallel with yoke.
What both arms joined is welded with two kinds of structures.A kind of is three same yokes are placed on steel plate draw close.Left, yoke two ends are concordant in yoke rear end, push down the yoke on both sides, take that yoke middle away, support between two yoke rear ends with one section and the contour wide square box block of yoke, concordant with yoke rear end, and concordant with plane on yoke.Soldering frame block.Then use above-mentioned " ┓ " shape fork handle, its socle is vertically welded on square box, on fork handle, square frame block points to left, and its extended line is still parallel with two yokes.This structure joins hereinafter referred to as A both arms.The another kind of structure of both arms connection is: as stated above two identical yokes are pressed on steel plate, yoke rear end left, take down that yoke middle, two socles of " ㄇ " shape fork handle are vertically welded on two yoke rear ends in plane respectively, concordant with yoke rear end.Again with the left side of one section of frame block butt welding on " ㄇ " shape fork handle square frame block identical with the cross-sectional plane that above-mentioned A yoke joins that section of fork handle left, concordant with plane on " ㄇ " shape frame block, and vertically.This section of frame block on butt welding also points to the left side.This structure is called that B both arms join below.
Fork handle alleged is below all that special fourchette handle points to this section of the left side.Fork handle on single armed connection also refers to and points to that section of contrary frame block with yoke above fork handle.
According to the characteristic of fork loading thing, the yoke connection of above-mentioned different structure can be applied, form the yoke group of different purposes to be arranged on telescopic arm forklift.For pitching dress carrying casing class goods, carton, wooden case, vegetable melon and fruit case, not bery soft at the bottom of case, two single armed joint groups can be selected to become a yoke group, and a yoke group only has two yokes.Or select single armed connection, a B both arms joint group to become yoke group, a yoke of single armed connection is placed between two yokes of both arms connection, and a yoke group has three yokes.
For pitching dress bag cargo, grain sack, fertilizer bag, bag of cement, various raw material bag etc., all softer on inner bag face, be suitable for selecting two both arms connection, become yoke group with an A both arms connection with a B both arms joint group, a yoke group has four yokes.
A telescopic arm forklift installs two yoke groups.For pitching the quite soft packed object of dress carrying, the suitable yoke joint group of three yoke compositions of selecting becomes yoke group, six roots of sensation yoke altogether, or selects the yoke joint group of four yoke compositions to become yoke group, totally eight yokes.
Vertical balladeur train is connected with level and smooth frame, mutually vertically, becomes " ┛ " shape.Vertical is vertical balladeur train, and centre has notch.There is slideway on notch both sides, slideway are provided with vertical slide block.Fork handle passes the notch in the middle of vertical balladeur train from " ┛ " shape frame right side.Vertical slide block lower end is fixed on fork handle head.Hoist cylinder upper end is fixed on the fixing support in vertical balladeur train upper end, and piston rod is fixed on the support of vertical slide block lower end.Level and smooth frame is arranged on and advances on slide plate.Pallet fork hanging block is connected and fixed with being fixed on to advance above the support on slide plate both sides.Together with propelling slide plate is vertically fixed on pushing plate.Advance on slide plate and have chute.Level and smooth frame there is corresponding slide block be arranged in the chute advancing slide plate.Propelling cylinder is fixed on fork handle head.Propelling cylinder piston rod front end is provided with slide plate, pushing plate has corresponding chute.When hoist cylinder drives vertical slide block and fork handle lifting, propelling cylinder also will along with horizontal rise and fall, and the slide plate on its piston rod end can upper and lower slip in the chute of pushing plate, is consistent with propelling cylinder.
Each yoke is associated with a set of independently jacking system and propelling unit.
The combination yoke principle of work of telescopic arm forklift: the combination yoke fork of telescopic arm forklift loads limit when not inserting the object in space, first inserts 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.Then to lift object motionless for the rising of yoke connection, and another yoke connection declines, and proceeds to setpoint distance, and rising again, it is motionless to lift object.Previous yoke connection declines again, advances, rises, and so alternately lifts object, alternately advances, until following inserted through object, i.e. and liftable carry an object.During unloading, goods is lifted and is transported to above placement location, and two yokes of each yoke group join alternately rising and lift goods, and alternately decline, retreat, all exit goods below, namely goods puts off in rest area.The lifting of yoke, advance, retrogressing are completed by control system control circuit and oil cylinder.Control system is Non-follow control and the mode automatically controlling to combine.
The combination yoke of telescopic arm forklift has propelling Lengthened slide plate type and advances slide plate coventional type two kinds of structures.Advance Lengthened slide plate type corresponding propelling cylinder peace balladeur train also will lengthen.In yoke advances, telescopic arm forklift can keep motionless, advance slide plate peace balladeur train can once provide yoke after repeatedly alternate intervals advances can inserted through pitch and lift the following advance distance of object.This model, propulsive units is long, but still can be no more than existing mechanism of telescopic handler length, because combination yoke is often short than existing mechanism of telescopic handler.Advance slide plate coventional type to inject in casing or the following process of packed object at yoke, telescopic arm forklift wants driven forward one to three time, during the level and smooth frame advanced on slide plate is pushed ahead several times, leaves this segment distance elimination of pushing plate.During telescopic arm forklift advances, yoke has dropped on following goods or on the ground, pushed down by top goods, resistance is very large, can not advance, and only has level and smooth frame can slide on propelling slide plate.Telescopic arm forklift pushes ahead cooperation, can reduce the length advancing slide plate, propelling cylinder peace balladeur train.
The present invention is applicable to pitch the not bery heavy case kind article body of dress.Carton, wooden case, plastic box, braiding case etc., the seamed edge of case kind article body top and bottom is not acute angle, has fillet more or less.Yoke front end wedge mouth can inject in the narrow slit of 0.5 mm wide, as long as inject a bit, second time is inserted darker.Packed object better pitches dress because every bag of packed object fill rear bulging high be in the middle of sack, sack dual-side has contraction-like inclined-plane.After bagged articles is stacked, be very close to each other in the middle of between every two bags.Yoke is first lifted from depths, inclined-plane, can pull open the space between two bags gradually.Yoke alternately injects, and does not rub to bag surface.Fork pack dress object, according to circumstances, once fork does not fill four to seven layers not etc.
The invention has the beneficial effects as follows: can pitch and load the object that pallet fork space is not inserted on limit, as casing class, packing bundling class, packed type objects.The storehouse of now small-sized socially dispersion, case class, the packed type objects of stacking are many especially.These goods are all in layer piles, and telescopic arm forklift cannot pitch dress at all.Especially get on and off, the overwhelming majority is a dead lift.Labour intensity is very large, and workman is very arduous, and efficiency is also very low.The invention solves above-mentioned stack goods by a difficult problem for machinery fork dress, the labour intensity of workman to be alleviated, and improve work efficiency.

Detailed description of the invention
Accompanying drawing and following describing are all advance slide plate coventional type for example.
In Fig. 1, be the combination yoke integral structure of telescopic arm forklift and the situation map be arranged on telescopic arm forklift.The front door frame 2 of telescopic arm forklift 1 hangs pallet fork hanging block 3.Pallet fork hanging block 3 is parts that pallet fork is connected with telescopic arm forklift, can sway, the distance between adjustment pallet fork.Slide plate 13 both sides are advanced to be fixed with support 5.Pallet fork hanging block 3 is connected and fixed with being fixed on to advance above the support 5 on slide plate 13 both sides.Advance that slide plate 13 is vertical with pushing plate 4 fixes, found balladeur train 7 and be connected with level and smooth frame 11, mutually vertically.A telescopic arm forklift is installed two yoke groups 10.Relevant mark is see Fig. 5.
In Fig. 2, be that two single armed joint groups become a yoke group constructional drawing.Yoke 14 front end becomes wedge-like.Yoke 14 seamed edge has fallen angle, very smooth." ┓ " shape fork handle socle is vertically welded in plane on yoke 14 left end.Top fork handle points to the left side, parallel with yoke.
In Fig. 3, be that a single armed connection becomes a yoke group constructional drawing with a both arms joint group.The socle of difference vertical welding " ㄇ " shape fork handle 9 above two yoke 14 rear ends of both arms connection.On " ㄇ " shape fork handle, one section of fork handle 9 has been welded on the square frame block left side, concordant with plane on " ㄇ " shape fork handle, and vertically.A yoke 14 of single armed connection in the middle of the both arms di-root yoke 14, can before and after, move up and down freely.
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.It is the yoke group that two single armed joint groups of picture become.Contrast Fig. 5 and Fig. 6 observes.In order to observe conveniently, the support 5 having taken down pallet fork hanging block 3 in Fig. 5 in Fig. 6, be connected with vertical slide block 8 with vertical balladeur train 7.
One in two yoke connection of a yoke group can only be seen in Fig. 5.Vertical balladeur train 7 is connected as a single entity with level and smooth frame 11 and mutually vertical.Have notch in the middle of vertical balladeur train 7, notch both sides are slideways, are provided with vertical slide block 8 in slideway.The fork handle 9 of yoke group 10 is from the right through the notch in the middle of vertical balladeur train, and vertical slide block 8 lower end is fixed on above the termination of fork handle 9 through the vertical balladeur train left side.The upper end of hoist cylinder 6 is fixed on the support 5 that is connected with vertical balladeur train 7.Piston rod 16 lower end of hoist cylinder be connected to be fixed on vertical slide block lower end support 5 on.Propelling cylinder 12 is connected on fork handle 9 termination, and support 5 has anchor ear to fix propelling cylinder 12, in order to avoid beat.Piston rod 16 termination of propelling cylinder 12 is fixed with slide plate 15, is arranged in the respective slide slots of pushing plate 4.While hoist cylinder drives vertical slide block that fork handle is elevated, propelling cylinder 12 is also driven to move up and down.The piston rod 16 of propelling cylinder 12 is also along with moving up and down, and the slide plate 15 of its termination just slides up and down in the chute of pushing plate 4.Level and smooth frame 11 there is slide block, is arranged in the chute of propelling slide plate 13.Propelling cylinder 12 makes piston rod extend and shortens, but piston rod end is fixed in the chute of pushing plate by slide plate 15, 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 17 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.
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.1,1, No. 3 yoke is motionless in initial position.2, No. 4 yokes advance, and the wedge mouth of yoke front end injects institute and pitch the gap of lifting between casing and following object, and reeve a bit.Then these two yokes are lifted a bit, pry open and expand some gaps, keep motionless.In 2, Fig. 8,1, No. 3 yoke advances at once, and front end wedge mouth inserts by the gap pried open, inserts darker.Then lift suitable height on, keep motionless.In 3, Fig. 9,2, No. 4 yokes advance at once, and 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 organize 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 two to three times, available Non-follow control operation, press autokeyer, yoke inserts the overall process below whole casing later, all controls hoist cylinder by autonomous cruise speed system follow procedure, propelling cylinder 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, by existing telescopic arm forklift operating mode operation.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, the combination yoke be mounted on telescopic arm forklift is carrying out fork dress carrying bag cargo flow diagram.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.
Insert in goods 18 times crack approach at yoke, if propelling cylinder interval alternately advances fork handle to drive yoke to advance, until following inserted through goods.Telescopic arm forklift 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, telescopic arm forklift is motionless.The propelling unit that this telescopic arm forklift is installed and yoke total length, still can be no more than original mechanism of telescopic handler length.Because fork dress bag cargo and casing class, combination yoke itself is not long, and the half of not enough existing mechanism of telescopic handler is 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, chaufeur obtains signal, driving advance one segment distance, and yoke is motionless.Telescopic arm forklift makes the oil pipe on propelling cylinder inner carrier both sides all communicate with oil extraction case before advancing, namely identical with barometric pressure.During telescopic arm forklift advances, push piston bar enters oil extraction case the oil of right for oil cylinder section.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 telescopic arm forklift advances, yoke is motionless.Yoke repeatedly intermittent leaves this segment distance of pushing plate and is eliminated in advancing.Yoke can restart to advance.Telescopic arm forklift moves propelling, in 1 to 3 underrange just.This structure, can reduce the length of propelling unit.
Corresponding control handle, button, keyboard is increased, in order to circuit and the oil circuit of control combination yoke in telescopic arm forklift operator's compartment.Control system is Non-follow control and the mode automatically controlling to combine.
Vertical balladeur train front is provided with camera, attached not shown in FIG..Make chaufeur can observe goods gap, telescopic arm forklift front end situation, be convenient to yoke and accurately inject gap.
