Description
Technical field
The present invention relates to fork truck roll adjustment fork.
Background technology
Fork truck be mainly with pallet fork for mainly getting the thing instrument, rely on the hydraulic lifting oil cylinder to realize dragging of goods got and lifting, realize the loading and unloading vehicle of goods level carrying by the tire traveling gear, in can carrying out, short-range transportation and loading and unloading, stacking.
Fork truck mainly contains power system, driving system, steering swivel system, brake system, hoisting system, car body and operator's compartment, hydraulic efficiency pressure system, electric system etc. and partly forms.Can lifting, inclination, can be widely used in cargo handing, stacking and the transportation of departments such as wood working, harbour, station, warehouse, oil field, metallurgy, machinery, building, improved work efficiency greatly.Various countries' stock production is one of the logistics of recoverable amount maximum in the world and loading-unload machine.
When fork truck carried out the handling operation, hoisting system directly bore entire cargo weight, and the equipment of operation such as the fork of finishing goods is got, carrying, lifting, piling.Hoisting system mainly is made up of parts such as outer mast, inner upright mounting, goods shelf, pallet fork, chain, lift oil tank and dump rams.
Since the fork truck use occasion, the difference of handling goods, and common pallet fork is got the unicity of function because of fork, and can't satisfy the needs in all many operating environments.Lift truck attachment is the part of fork truck equipment, its rational Application fork truck is become have fork, folder, liter, rotation, sidesway, push-and-pull or tumble etc. high-mobility, multipurpose, wheeled vehicle, dynamical material handling instrument, enlarged the range of use of fork truck widely, improve the handling efficiency of fork truck, promoted the raising of the automation development level of material handling industry.
The lift truck attachment kind be a lot of and function different, to adapt to the different work environment requirement, its sorting technique also is not quite similar.Often the relation according to the required oil circuit of accessory is divided into mechanical type accessory and fluid pressure type accessory with accessory, and the former need not additional oil circuit, and the former fork truck equipment two class oil circuits that only hoist, tilt are joined two plate valves; As: boom, crane arm, folding pallet fork etc.But the latter need add in addition and join (one group or two groups) additional oil circuit, join one group of additional oil circuit be commonly referred to three plate valve accessories, accessory possesses a kind of simple function; Join the four plate valve accessories that are commonly referred to of two groups of additional oil circuits, accessory possesses two kinds of simple functiones; By that analogy, a kind of simple function of every increase just need add one group of additional oil circuit, and multichannel valve block number also can increase a slice.As: sideshifter (three plate valve accessories), rotating clamp (four plate valve accessories), pusher (three plate valve accessories) etc.
The sidesway roll adjustment of large-tonnage fork truck fork generally all is split type in the world at present, because what the goods shelf of some large-scale fork truck used is that the screw mandrel formula is regulated, even cause the product of foremost in the world accessory producer can not be applied to this type of goods shelf, because such integral type accessory has certain degree of difficulty on structure design, so no matter still all are barren grounds at home abroad.
Technically there is following deficiency in existing split type sidesway roll adjustment fork: (1) can only be supporting on the coupling type goods shelf; (2) need the pedestal of the goods shelf of complete machine producer as accessory; (3) front overhang of split type sidesway roll adjustment fork is bigger than integral side displacement range regulation roll adjustment fork.
Summary of the invention
The objective of the invention is: provide a kind of before function, the roll adjustment fork of goods shelf with sidesway be superimposed upon before integral side displacement range regulation fork of large tonnage fork lift on the goods shelf.
Concrete structural design scheme is as follows:
Integral side displacement range regulation fork of large tonnage fork lift comprises interior goods shelf, preceding goods shelf and two pallet forks, and preceding goods shelf is for falling the door shape, its middle part level is provided with pallet fork load-bearing axle, two pallet fork tops socket respectively pallet fork load-bearing axle, and interior goods shelf vertically is positioned at preceding goods shelf rear portion, it is characterized in that:
Interior goods shelf 1 top is fixedly connected with horizontal axle sleeve 4, load-bearing axle 2 is plugged in the axle sleeve 4, the both sides upright arm of goods shelf 6 before load-bearing axle 2 two ends difference captive joint, load-bearing axle 2 parallel beneath are provided with sidesway oil cylinder 5, one end of sidesway oil cylinder 5 is connecting preceding goods shelf 6 one side upright arms, and the other end is connecting axle sleeve 4 outsides;
The afterbody of the roll adjustment oil cylinder that the upright arm inboard, both sides of preceding goods shelf 6 is connecting respectively, head one end of left side roll adjustment oil cylinder 10 is connecting right fork, and head one end of right side roll adjustment oil cylinder 3 is connecting left pallet fork;
Interior goods shelf 1 is installed on the inner upright mounting of fork truck.
Integral side displacement range regulation fork of large tonnage fork lift according to last is characterized in that: the head end captive joint of described sidesway oil cylinder 5 preceding goods shelf 6 one side upright arm inboards, and the afterbody end axle sleeve 4 outsides by the contiguous block captive joint.
Integral side displacement range regulation fork of large tonnage fork lift according to claim 1 is characterized in that: goods shelf 1 is located on the inner upright mounting of fork truck by main roller 9 in described.
Useful technique effect of the present invention is embodied in several aspects:
1, this integral side displacement range regulation roll adjustment fork is the stack of first sideshifter, roll adjustment fork and goods shelf product on the present large-tonnage fork truck by existing four plate valve accessory improvement are obtained, and directly is contained in the inner upright mounting by roller.It is little to have front overhang, and load-carrying capacity is big, the advantage of compact conformation.
2, this device pipeline system trend is reasonable, stable performance; Product is finished 40 hours industrial intensive tests.
3, the present invention is two fork interlocks, whole sidesway, four plate valve settings; Simple in structure, reasonable in design.
4, this device also can with the supporting use of screw mandrel formula goods shelf.
