Fig. 3 is a block diagram of the present utility model;
Fig. 4 is the right side view of Fig. 1;
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 to Fig. 4 shows an embodiment of the wide visual field of the utility model forklift door frame.It comprises with the inner upright mounting 1 of left and right inner column 11 and an outer mast 2 with left and right outer column 21.One hoist chain 4 and lift oil tank 3 respectively is set in the outside of the left and right outer column 21 of outer mast.
Outer mast is provided with outer mast guide rail 10, inner upright mounting is provided with inner upright mounting guide rail 9, inner upright mounting can move along described outer mast guide rail 10, the bottom of outer mast is provided with door frame supporting shaft 7, outer mast connects the goods shelf 5 of a belt track, the goods shelf track connects a pallet fork 6, and goods shelf can move along inner upright mounting track 9, shown in Fig. 1,2,3.
Door frame is provided with the lift oil tank 3 of interconnective band piston rod 13 and the chain 4 that hoists, and the chain 4 that hoists disposes sprocket wheel 14, and sprocket wheel 14 disposes chain pulley seat 12, and chain pulley seat 12 is fixedly installed on the crossbeam 15 of inner upright mounting 1.Chain pulley seat 12 is connected with the top of piston rod 13 again.
The vertical center line of the left and right outer column 21 of the vertical center line of supporting shaft 7 and outer mast, the vertical center line of lift oil tank 3 coincide, referring to shown in Figure 4.This design has solved the following deficiency that domestic and international forklift door frame in use exists preferably:
The problem that the manufacture difficulty of first inner upright mounting 1 and outer mast 2 is big makes technology simple, and productive costs reduces.
It two is the generations that solved inner upright mounting 1 and goods shelf 5 stuck phenomenon when zero load descends preferably, has improved the kinematic accuracy of door frame.
It three is improved door frame and oil cylinder when heavily loaded preferably stressed, has prolonged the service life of door frame guide rail and roller.Lift oil tank 3 and chain 4 are placed on the door frame both sides, have improved the stressing conditions of lift oil tank 3, reduced the wearing and tearing of lift oil tank, improved the lateral stability when goods hoists, widened operator's the visual field; With supporting base 7 design of door frame bottom centre at outer mast 2 columns, can be bigger reduce door frame and do the hypsokinesis campaign time pulling force, make the stressed ILS that reduces of dump ram.
The principle of work of the wide visual field of the utility model forklift door frame is: the goods shelf 5 that is connected with outer mast 2 is linked in together by roller 8 and inner upright mounting 1, and goods shelf can move along the inner orbit 9 of inner upright mounting 1.Roller 8 is equipped with in the upper end of the lower end of inner upright mounting 1 and outer mast 2, and inner upright mounting 1 can be moved along outer guide 10 directions of outer mast 2.Pallet fork 6 is contained on the track of goods shelf 5, but and direction along ng a path adjust distance between two pallet forks.
When the oil inlet of pressure oil below lift oil tank 3 of hydraulic efficiency pressure system enters oil cylinder, under the effect of pressure oil, promote piston rod 13 upward movements, both sides chain pulley seat 12 on the inner upright mounting 1 links to each other with the top of piston rod 13, this moment is under the promotion of piston rod 13, inner upright mounting 1 is along outer guide 10 upward movements of outer mast, and this moment, the lifting velocity of inner upright mounting 1 was consistent with the ascending velocity of piston rod.
The sprocket wheel 14 that drives on the crossbeam 15 that is contained in inner upright mounting 1 when inner upright mounting 1 rises rises together, chain 4 is on sprocket wheel 14, two of chain 4 two ends connect first end and link to each other with chain stays 51 on the goods shelf 5, the other end links to each other with the chain stays 22 of outer mast 2 upper ends, when rising with inner upright mounting 1, sprocket wheel 14 rotates simultaneously, drive chain stays 51 risings that chain links to each other with goods shelf 5, under the pulling of chain force, goods shelf 5 rises along inner upright mounting 1, pallet fork 6 together rises with goods shelf 5, and this moment, the speed of pallet fork 6 and goods shelf 5 was twices of piston rod 13 ascending velocity in the oil cylinder.
And the door frame column adopts rolling shaped material, do not need machinework, can enhance productivity, but door frame in the past is for improving the accuracy of manufacture of door frame, reduce welding deformation, cost-cutting must be innovated on the structure design of door frame, this design is to carry out under above technical background, has solved the problem that in the past existed preferably by trial-production and detection; Make the performance of fork truck that bigger improvement arranged.
The wide visual field fork lift door frame structure of the utility model compares with at present domestic and international similar forklift door frame, and difference is this The lift oil tank of door frame and hoisting chain are placed on the dual-side of door frame column; The supporting-point of door frame is in door frame column center Bottom, make the structure of door frame more succinct, stressed more reasonable, the easier assurance of the kinematic accuracy of door frame, production technology more Can reduce cost of manufacture simply again.
