Summary of the invention

The object of the present invention is to provide a kind of dress of both can having pitched to carry the goods having pallet fork to insert space below, the combination yoke in the mechanism of telescopic handler of the goods not having pallet fork insertion space below can be carried again.

The present invention is achieved in that the combination yoke in mechanism of telescopic handler, is arranged in mechanism of telescopic handler.Combination yoke in mechanism of telescopic handler joins jacking system by interdigital, yoke connection, yoke group, yoke, yoke joins propelling unit, fork box, blocking device, control system form.Yoke front end is provided with interdigital.A yoke connection is made up of a fork handle and one to four two 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, 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.Each installation yoke group on two pallet forks of a telescopic arm forklift.Advance on the support on slide plate both sides and be fixed with fork box.Fork box is provided with blocking device.When combination yoke wants operation, the pallet fork of telescopic arm forklift injects fork box, and locked device locks.The lifting of yoke connection, advance, retrogressing, interdigital rotation, is completed by control system control circuit and oil circuit.Fork loads limit when not having pallet fork to insert the goods in space, each yoke group is first inserted in the gap between goods and following object that will carry with the interdigital front end wedge mouth of yoke connection, interdigital upper turning is lifted a bit by any or yoke, pry open and expand some gaps, another yoke joins interdigital front end and injects this goods at once below by the gap that levers up, alternately lever up, inject, it is following that whole yoke front end is inserted into goods, so latter two yoke connection alternately rising to lift goods motionless, decline, proceed to setpoint distance, alternately to lift goods motionless in rising, 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.

Yoke is hollow metal cuboid.Yoke front end is provided with interdigital.Yoke front end dual-side has pin hole.There is pin hole at interdigital head center, is hinged in yoke front end shell interdigital with pivot pin.Interdigitally can to rotate.Interdigitally can to rotate clockwise, downwards, to turn round, namely receive backward.Interdigital can inhour to turn to interdigital upper plane concordant with plane on yoke, this is the end position upwards rotated forward, hereinafter referred to as " interdigital concordant ".Interdigital front end becomes wedge mouth shape.Corner angle are smooth, can insert in the narrow slit of 0.5 millimeter.

In the cavity of yoke front housing section, installed a small oil tank, its piston rod front end is connected with connecting rod.The connecting rod position corresponding to interdigital below is hinged.Small oil tank can control interdigital rotation direction and angle.Said yoke includes interdigital below.

Yoke connection is divided into single armed to join and both arms connection.Single armed connection is that a fork handle is connected with a yoke, and both arms connection is that a fork handle is connected with two yokes.

Single armed connection is the socle of vertical welding " ┓ " shape fork handle in plane on an interdigital yoke rear end up 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 lain 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.

Each installation yoke group on two pallet forks of a telescopic arm forklift.

Vertical balladeur train is connected with level and smooth frame, orthogonal, 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.Skateboard back-end is advanced to be fixed with pushing plate, and orthogonal.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, is arranged in the corresponding chute of pushing plate.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.Slide plate both sides are advanced to be fixed with support.Support is fixed with fork box.Fork box is provided with blocking device.Vertical balladeur train front is provided with camera.

Each yoke is associated with a set of independently jacking system and propelling unit.

Combination yoke principle of work in mechanism of telescopic handler: fork loads limit when not having pallet fork to insert the object in space, and two pallet forks of telescopic arm forklift inject combination yoke respectively and advance in the fork box on slide plate, and locked device locking.First insert with the interdigital front end wedge mouth on the yoke of each yoke connection in two yoke groups and be handled upside down object and below between object in gap.Turn a bit on interdigital, or 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 interdigital front end on the yoke 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, interdigital rotation is completed by control system control circuit and oil cylinder.Control system is Non-follow control and the mode automatically controlling to combine.

Combination yoke in mechanism of telescopic handler 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.Interdigital front end wedge mouth on yoke 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.The interdigital elder generation of yoke lifts from depths, inclined-plane, can pull open the space between two bags of objects 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.

After mechanism of telescopic handler having been installed combination yoke, can pitch and load the object that there is pallet fork insertion space on limit, can pitch again and load the object that limit does not have pallet fork insertion space.No matter whether not bery heavy object, have pallet fork to insert space below, directly with combination yoke fork dress.For very heavy object, telescopic arm forklift can take out pallet fork from fork box, with the object that pallet fork fork dress is very heavy.Greatly expand the range of use of telescopic arm forklift.

Detailed description of the invention

Accompanying drawing and following describing are all advance slide plate coventional type for example.

In Fig. 1, be that combination yoke is arranged in mechanism of telescopic handler and combination yoke integral structure figure.Two pallet forks 5 on the front door frame 2 of telescopic arm forklift 1, inject in fork box 3 fixing on combination yoke respectively.And locked device 4 locks.Namely combination yoke is arranged on the pallet fork of telescopic arm forklift.The vertical peaceful balladeur train 13 of balladeur train 8 is connected, and orthogonal.Fork handle 10 in yoke group 12, through vertical balladeur train 8 back side, is connected with vertical slide block 9.Level and smooth frame 13 is arranged on and advances on slide plate 15.Simultaneously see Fig. 5.Advance slide plate 15 both sides to be fixed with support 7, support 7 is fixed with fork box 3.Blocking device 4 is arranged on fork box 3.Blocking device is screwed on pallet fork in corresponding pit, in order to fixing pallet fork 5 with screw.

In Fig. 2, it is the constructional drawing that yoke structure and two single armed joint groups become a yoke group.In order to observe conveniently, in Fig. 2, take down yoke 17 leading portion front that piece of wall thickness.Yoke 17 is hollow cuboids.Yoke 17 seamed edge has fallen angle, very smooth.Interdigital 11 are hinged in yoke 17 front end shell with pivot pin.Interdigital 11 one-tenth wedge-likes, on it, plane can turn to concordant with plane on yoke.A small oil tank 18 has been installed in piece housing before yoke.Namely oil cylinder is hydraulic actuating cylinder, comprises piston rod.Piston rod 20 front end of small oil tank 18 has been hinged one section of connecting rod 22.Connecting rod 22 other end and interdigital 11 following company's blocks are hinged.Piston rod 20 is through guide section 19.Guide plate 21 is had above the right of guide section 19.Small oil tank 18 can control direction and the angle of interdigital rotation." ┓ " shape fork handle socle is vertically welded in plane on yoke 17 left end.Top fork handle points to the left side, parallel with yoke.

In Fig. 3, be that a single armed joins the yoke group constructional drawing become with a both arms joint group.The socle of difference vertical welding " ㄇ " shape fork handle 10 above two yoke 17 rear ends of both arms connection.On " ㄇ " shape fork handle, one section of fork handle 10 has been welded on the square frame block left side, concordant with plane on " ㄇ " shape fork handle, and vertically.A yoke 17 of single armed connection in the middle of the both arms di-root yoke 17, 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.Contrast Fig. 5 and Fig. 6 observes.In order to observe conveniently, in Fig. 6, take down in Fig. 5 the support 7 pitched box 3 and be connected with on propelling cylinder 14 and with vertical balladeur train 8.

One in two yoke connection of a yoke group can only be seen in Fig. 5.Vertical balladeur train 8 is connected as a single entity with level and smooth frame 13 and mutually vertical.Have notch in the middle of vertical balladeur train 8, notch both sides are slideways, are provided with vertical slide block 9 in slideway.The fork handle 10 of yoke group 12 is from the right through the notch in the middle of vertical balladeur train, and vertical slide block 9 lower end is fixed on above the termination of fork handle 10 through the vertical balladeur train left side.The upper end of hoist cylinder 6 is fixed on the support 7 that is connected with vertical balladeur train 8.Piston rod 20 lower end of hoist cylinder be connected to be fixed on vertical slide block lower end support 7 on.Propelling cylinder 14 is connected on fork handle 10 termination, and support 7 has anchor ear to fix propelling cylinder 14, in order to avoid beat.Piston rod 20 termination of propelling cylinder 14 is fixed with slide plate 23, is arranged in the respective slide slots of pushing plate 16.While hoist cylinder drives vertical slide block that fork handle is elevated, propelling cylinder 14 is also driven to move up and down.The piston rod 20 of propelling cylinder 14 is also along with moving up and down, and the slide plate 23 of its termination just slides up and down in the chute of pushing plate 16.Level and smooth frame 13 there is slide block, is arranged in the chute of propelling slide plate 15.Propelling cylinder 14 makes piston rod extend and shortens, but piston rod end is fixed in the chute of pushing plate by slide plate 23, 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 24 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. 8,1, 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 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, be that combination yoke is arranged on and mechanism of telescopic handler carries out fork and fill 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.

Insert in goods 25 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, telescopic arm forklift obtains signal, chaufeur 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.Telescopic arm forklift 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 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 1 to 2 time just.This structure, can reduce the length of propelling unit.

High pressure oil on combination yoke needed for hydraulic actuating cylinder, involves oil pipe supply from telescopic arm forklift.Corresponding control handle, button, keyboard is increased in telescopic arm forklift operator's compartment, in order to circuit and the oil circuit of control combination yoke, i.e. control combination yoke riser, propelling unit and interdigital action.

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.
