Abstract
The present invention relates to a 25 tons hoister of an empty box stacker, which needs to solve the problem of providing a lengthened oil cylinder which can be stably used and largely prolong the service life. The present invention is characterized in that a strip-shaped guide plate is arranged on an outer mast assembly on one side adjacent to a hoisting oil cylinder, and two guiding slide blocks which are matched with both sides of the guide plate in the vertical direction are respectively arranged on the head of the hoisting oil cylinder. The present invention can effectively guide the movement of the head of the hoisting oil cylinder, the operating stability of the oil cylinder is enhanced, and the service life of the oil cylinder is prolonged. The present invention has the advantages of simple structure and convenient maintenance.
Description
Technical field
The present invention relates to 25 tons of empty van Forklifts, specifically 25 tons hoister of ampty box stacker.
Background technology
At present, be used for the 25T empty van Forklift of harbour or container production producer, be specifically designed to the empty freight container of loading and unloading.The height of container stacking can reach 2.6 meters surplus 20 rice do not wait, require the lift oil tank of Forklift to rise like this and be raised to this height, then can operation.Because lifting altitude is bigger, require lift oil tank that the stroke of sufficient length is arranged, and to guarantee that oil cylinder normally moves bias free, and guarantee that the freight container that is hoisted does not produce inclination, like this lift oil tank and the small size flexural deformation of piston rod are required to reach a higher level.Now lift oil tank (shorter) usefulness of fork truck industry all is movable oil cylinder cylinder head, if 25T empty van Forklift lift oil tank also adopts movable cylinder head, its amount of deflection will be very big so, can have a strong impact on to use and the shortening life-span.25T empty van Forklift lift oil tank will face an acid test as with existing movable cylinder head.
Summary of the invention
The objective of the invention is: 25 tons hoister of ampty box stacker that provide a kind of oil cylinder that extends to stablize use, increase the service life significantly.
Concrete structural design scheme is as follows:
1,25 tons hoister of ampty box stacker comprise outer mast assembly, inner upright mounting assembly, lift oil tank and suspender, it is characterized in that:
On the outer mast assembly door frame sidewall of an adjacent side with lift oil tank, vertically be fixed with strip guide plate 3 from top to bottom, two guide runners 7 that cooperate with guide plate 3 vertical direction both sides are located at respectively on the oil cylinder cylinder head 4 of lift oil tank 5;
Guide runner 7 is a n type fitting surface with the fitting surface of guide plate 3 vertical direction both sides.
2, described guide runner 7 is provided with the groove that cooperates with guide plate 3 vertical direction sidewalls, is provided with the wear-resisting pasting board 9 that coats its inside face in the groove.
3, the material of described wear-resisting pasting board is a high molecule plastic.
Useful technique effect of the present invention is embodied in several aspects:
1, the present invention has overcome existing movable cylinder head oil cylinder as the flexible limitation that extends, on the oil cylinder cylinder head, increase guide runner, and this guide runner is moved along the guide plate that fixes, Yun Hang oil cylinder does not almost have flexural deformation like this, can effectively guide the motion of lift oil tank cylinder head.
2, the present invention not only makes the oil cylinder lengthening become possibility, and has improved the oil cylinder operation stability greatly, and also prolong significantly the service life of oil cylinder.
3, this apparatus structure is simple, and is easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the F-F cutaway view of Fig. 1,
Fig. 3 is the partial enlarged drawing of Fig. 2,
Fig. 4 is guiding slope mass structure enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described by embodiment.
Embodiment 1:
25 tons hoister of ampty box stacker comprise outer mast assembly 1, inner upright mounting assembly 2, lift oil tank 5 and suspender 6.
With on the door frame sidewall of the outer mast assembly 1 of lift oil tank 5 adjacent sides, vertically be installed with strip guide plate 3 by contiguous block 8 from top to bottom, two guide runners 7 that cooperate with guide plate 3 vertical direction both sides are installed on respectively on the oil cylinder cylinder head 4 of lift oil tank 5.
Guide runner 7 is a n type fitting surface with the fitting surface of guide plate 3 vertical direction both sides.
During work, coat lubricating oil, adjust the gap of guide runner 7 and guide plate 3, guide runner 7 and guide plate 3 can slide relative be got final product freely on the surface of guide plate 3.
Embodiment 2,
Have the groove that cooperates with guide plate 3 vertical direction sidewalls on the guide runner 7, the groove internal fixation has the wear-resisting pasting board 9 that coats its inside face.The material of wear-resisting pasting board 9 is a high molecule plastic.
Claims (3)
1,25 tons hoister of ampty box stacker comprise outer mast assembly, inner upright mounting assembly, lift oil tank and suspender, it is characterized in that:
On the outer mast assembly door frame sidewall of an adjacent side with lift oil tank, vertically be fixed with strip guide plate (3) from top to bottom, two guide runners (7) that cooperate with guide plate (3) vertical direction both sides are located at respectively on the oil cylinder cylinder head (4) of lift oil tank (5);
Guide runner 7 is a n type fitting surface with the fitting surface of guide plate (3) vertical direction both sides.
2,25 tons hoister of ampty box stacker according to claim 1 is characterized in that: described guide runner (7) is provided with the groove that cooperates with guide plate (3) vertical direction sidewall, is provided with the wear-resisting pasting board (9) that coats its inside face in the groove.
3,25 tons hoister of ampty box stacker according to claim 2 is characterized in that: the material of described wear-resisting pasting board is a high molecule plastic.
