Description
Technical field
The utility model relates to fork truck roll adjustment fork.
Background technology
The roll adjustment fork that fork truck is used need not manual shift pallet fork spacing, the driver can just can realize the two-way spacing adjustment of pallet fork by hydraulic control lever, the roll adjustment of domestic little tonnage fork truck fork oil cylinder guiding mechanism generally all is to lead by the special axis of guide at present, and the roll adjustment oil cylinder is used for doing roll adjustment specially and uses.The deficiency that existing roll adjustment is pitched technical existence has two aspects: the one, and, because the axis of guide has taken narrow and small inner space, in order normally to use common complex structure, huge; The 2nd, owing to have more 2 axis of guides, the deadweight of roll adjustment fork is bigger.
Summary of the invention
The purpose of this utility model is: provide a kind of little tonnage fork truck roll adjustment simple in structure, in light weight, that have self-lubricating function to pitch.
Concrete structural design scheme is as follows:
Little tonnage fork truck roll adjustment fork, comprise roll adjustment fork body, retaining shelf, about two pallet forks and two roll adjustment oil cylinders, and two roll adjustment oil cylinders are installed in parallel in retaining shelf inboard respectively, it is characterized in that: also comprise two shift forks, shift fork comprises fork body 8, axle sleeve 9 and connecting panel, and fork body 8 is the door font; Left side shift fork 2 is connected to form successively by fork body 8, axle sleeve 9 and connecting panel, and its axle sleeve 9 is set on the roll adjustment cylinder block in left side, and connecting panel is connecting the flexible end of right side roll adjustment oil cylinder; Right shift fork 5 is connected to form successively by fork body 8, connecting panel and axle sleeve 9, and its axle sleeve 9 is set on the roll adjustment cylinder block on right side, and connecting panel is connecting the flexible end of left side roll adjustment oil cylinder.
Be provided with coaxial self lubrication bearing in the axle sleeve 9 of described shift fork, the self lubrication bearing material is a spheroidal graphite iron, and 9 liang of axial ends of axle sleeve are respectively equipped with ring-type shrouding 7.
Useful technique effect of the present utility model is:
1, by improvement, need not the special axis of guide, the cylinder barrel of 2 roll adjustment oil cylinders respectively as the guide rail of shift fork, is simplified the structure, improved the kinematic accuracy height existing roll adjustment fork structure;
2, self lubrication bearing of the present utility model adopts, and to be spheroidal graphite iron QT450-10 omitted the work of daily grease lubrication as antifriction material, maintenance free.
3, owing to reduced by 2 axis of guides, the weight of whole device is also corresponding to be alleviated.
4, it is little to the utlity model has front overhang, and load-carrying capacity is big, the characteristics of compact conformation.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the lateral plan of Fig. 1,
Fig. 3 is left shift fork structural representation,
Fig. 4 is the lateral plan of Fig. 3,
Fig. 5 is right shift fork structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment 1:
Little tonnage fork truck roll adjustment fork comprise roll adjustment fork body 3, retaining shelf 4, about two pallet forks 10 and two roll adjustment oil cylinders 1, and two roll adjustment oil cylinders 1 are installed in parallel in retaining shelf 4 inboards respectively.
Also comprise two shift forks, shift fork comprises fork body 8, axle sleeve 9 and connecting panel, and fork body 8 is the door font.Left side shift fork 2 is connected to form successively by fork body 8, axle sleeve 9 and connecting panel, and its axle sleeve 9 is sleeved on roll adjustment oil cylinder 1 cylinder body in left side, and connecting panel is connecting the flexible end of right side roll adjustment oil cylinder; Right shift fork 5 is connected to form successively by fork body 8, connecting panel and axle sleeve 9, and its axle sleeve 9 is sleeved on roll adjustment oil cylinder 1 cylinder body on right side, and connecting panel is connecting the flexible end of left side roll adjustment oil cylinder.
Its principle of work is: roll adjustment oil cylinder 1 is under the oil pressure that the fork truck hydraulic efficiency pressure system provides, the roll adjustment that impeller left side shift fork 2 and right shift fork 5 are inwardly realized on the cylinder barrel of roll adjustment oil cylinder 1 simultaneously, outwards slided, the cylinder barrel conduct of the roll adjustment oil cylinder 1 of this moment the guide rail of left shift fork 2 and right shift fork 5.When left shift fork 2 and right shift fork 5 are promoted by roll adjustment oil cylinder 1, remove to promote left and right pallet fork 10 respectively and move along the guide rail notch on the roll adjustment fork body 3, realize just can realizing the function that the two-way spacing of pallet fork is adjusted by hydraulic control lever.
Embodiment 2:
In order to improve antifriction effect, in the axle sleeve 9 of left and right sides shift fork coaxial self lubrication bearing is installed all, the self lubrication bearing material is a spheroidal graphite iron, and 9 liang of axial ends of axle sleeve are equipped with ring-type shrouding 7 by tightening screw 6 respectively, self lubrication bearing is encapsulated in the axle sleeve 9, sees Fig. 3, Fig. 4 and Fig. 5.
Left side shift fork 2 contacts with the cylinder barrel outside face of roll adjustment oil cylinder 1 with right shift fork 5 Upper shaft sleeves 9 interior self lubrication bearings, plays the anti-attrition effect.
Other is with embodiment 1.
