Description

Forklift door frame
Technical field
The utility model relates to the fork truck technical field, particularly a kind of forklift door frame.
Background technology
Fork truck is an industrial transportation vehicle; Be meant to the member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short-distance transportation operation; Belong to material handling machinery; Being widely used in places such as station, harbour, airport, factory, warehouse, is the high-efficiency appliance of mechanized handling, stacking and short-distance transportation.At present, mostly the fork truck of producing and using is the two-stage portal-framed structure, comprises outer mast and inner upright mounting, and inner upright mounting has only one-level, and door frame is registered one's residence and highly is 2080mm, and the maximum lifting height is 3100mm.The fork truck application place of this two-stage portal-framed structure is limited, for example highly is lower than 2080mm registering one's residence, and the place that the maximum lifting height is higher than 3100mm just can not meet the demands, and can't use, and has had a strong impact on the range of use of fork truck.
The utility model content
The utility model purpose is in order to overcome above-mentioned deficiency, a kind of lift height wide ranges to be provided, and makes fork truck application place forklift door frame widely.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of forklift door frame; Comprise outer mast, said outer mast inner slide is provided with inner upright mounting, and first engine installation that is used to promote said inner upright mounting is installed between said outer mast and the said inner upright mounting; Said inner upright mounting comprises one-level inner upright mounting and secondary inner upright mounting; Said first engine installation is installed between said outer mast and the said one-level inner upright mounting, and said secondary inner upright mounting slides and is arranged at the inboard of said one-level inner upright mounting, between said secondary inner upright mounting and the said one-level inner upright mounting second engine installation that is used to promote said secondary inner upright mounting is installed; The top of said secondary inner upright mounting is provided with the prong assembly.
As a kind of improvement, said first engine installation and second engine installation are hydraulic ram.
The beneficial effect of the utility model is: because the said forklift door frame of the utility model comprises outer mast; Said outer mast inner slide is provided with inner upright mounting; First engine installation that is used to promote said inner upright mounting is installed between said outer mast and the said inner upright mounting; Said inner upright mounting comprises one-level inner upright mounting and secondary inner upright mounting, and said first engine installation is installed between said outer mast and the said one-level inner upright mounting, and said secondary inner upright mounting slides and is arranged at the inboard of said one-level inner upright mounting; Between said secondary inner upright mounting and the said one-level inner upright mounting second engine installation that is used to promote said secondary inner upright mounting is installed; Registering one's residence of the fork truck of this three grades of portal-framed structures highly can design highly lowlyer than registering one's residence of existing secondary mast forklift truck, is designed to 1780mm, can satisfy the low user of entry door height and use; Under the effect of first engine installation, can one-level inner upright mounting and secondary inner upright mounting be promoted simultaneously, when being promoted to the vertex of one-level inner upright mounting, the ground-surface relatively height of prong assembly can rise to 2490mm; Under the effect of second engine installation, can the secondary inner upright mounting be promoted; When being promoted to secondary inner upright mounting vertex; It is 3780mm that the ground-surface relatively height of prong assembly is promoted by 2490mm; Highly hang down 300mm so the registering one's residence of the existing fork truck of aspect ratio of registering one's residence of the fork truck of the utility model has been installed, the highest hoisting depth has enlarged the application place of fork truck greatly than the high 680mm of the highest hoisting depth of existing fork truck.
Description of drawings
Accompanying drawing is the structural representation of the utility model;
Among the figure: 1, outer mast, 2, the one-level inner upright mounting, 3, the secondary inner upright mounting, 4, the prong assembly, 5, the first moving device, 6, second engine installation.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.
Shown in accompanying drawing; A kind of forklift door frame; Comprise outer mast 1, outer mast 1 inner slide is provided with inner upright mounting, and first engine installation 5 that is used to promote inner upright mounting is installed between outer mast 1 and the inner upright mounting; Inner upright mounting comprises one-level inner upright mounting 2 and secondary inner upright mounting 3; First engine installation 5 is installed between outer mast 1 and the one-level inner upright mounting 2, and secondary inner upright mounting 3 slides and is arranged at the inboard of one-level inner upright mounting 2, and second engine installation 6 that is used to promote secondary inner upright mounting 3 is installed between secondary inner upright mounting 3 and the one-level inner upright mounting 2; The top of secondary inner upright mounting 3 is provided with prong assembly 4.Registering one's residence of the fork truck of this three grades of portal-framed structures highly can design highly lowlyer than registering one's residence of existing secondary mast forklift truck, is designed to 1780mm, can satisfy the low user of entry door height and use; Under the effect of first engine installation 5, can one-level inner upright mounting 2 and secondary inner upright mounting 3 be promoted simultaneously, when being promoted to the vertex of one-level inner upright mounting 2, the ground-surface relatively height of prong assembly 4 can rise to 2490mm; Under the effect of second engine installation 6, can secondary inner upright mounting 3 be promoted; When being promoted to secondary inner upright mounting 3 vertexs; It is 3780mm that the ground-surface relatively height of prong assembly 4 is promoted by 2490mm; Highly hang down 300mm so the registering one's residence of the existing fork truck of aspect ratio of registering one's residence of the fork truck of the utility model has been installed, the highest hoisting depth has enlarged the application place of fork truck greatly than the high 680mm of the highest hoisting depth of existing fork truck.
First engine installation 5 and second engine installation 6 are hydraulic ram.First engine installation 5 and second engine installation 6 are not confined to hydraulic ram this are a kind of, can also wait to substitute with motor hoist, and those skilled in the art is easy to make the embodiment of replacement, so be not described in detail in this.
Mentioned in the present embodiment register one's residence the height and the hoisting depth equidimension be a kind of embodiment of the best; Do not represent the embodiment that has only this a kind of size; What the utility model was mainly protected is this three grades of portal-framed structures that comprise outer mast 1, one-level inner upright mounting 2 and secondary inner upright mounting 3; Just different with present embodiment dimensionally, and the same or analogous forklift door frame of structure still falls into the scope of the utility model protection.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
