Description
Technical Field
The invention relates to the technical field of forklift parts, in particular to a high-lift portal frame of a forklift.
Background
At present, a forklift uses a large number of three-stage fully-free gantries. Namely, the door frame comprises an outer door frame, a middle door frame and an inner door frame which are sequentially clamped together and arranged from inside to outside. Wherein, this well portal can rise for this outer portal, this interior portal can rise for this well portal to the portal that can tertiary rise has higher rise height.
Generally, there are two arrangements adopted by the three-stage portal. The outer door frame, the middle door frame and the inner door frame are arranged by adopting C + J + J combined channel steel, the three channel steel are same in height, the front end faces of the three channel steel sequentially protrude forwards, and the upper ends and the lower ends of the matched left channel steel and the right channel steel are welded and connected by cross beams in a pairwise correspondence manner; and the outer door frame, the middle door frame and the inner door frame are arranged by adopting channel steel of C + I + I combination, the channel steel specifications of the middle door frame and the inner door frame are the same, the heights of the three channel steels are basically the same, the front end faces are sequentially protruded, and the upper ends and the lower ends of the left channel steel and the right channel steel which are matched are all formed by welding and connecting cross beams in a pairwise correspondence manner.
However, the front end faces of the channel steels in the two aforementioned 2 door frames are all protruded in sequence, which results in a larger front suspension distance of the door frame assembly and poorer cargo carrying capacity.

Detailed Description
Example, see figure 1: the forklift high-lift gantry comprises an outer gantry, a middle gantry and an inner gantry which are sequentially arranged from back to front (in the embodiment, the direction close to the forklift body 100 is the back, the direction far away from the forklift body 100 is the front, and the same is used below).
Furthermore, the left side and the right side of the outer door frame are respectively provided with a left channel steel 11 and a right channel steel 12 which are vertical. The opening of the left channel steel 11 faces to the right, the opening of the right channel steel 12 faces to the left, and the upper and lower ends of the left channel steel 11 and the upper and lower ends of the right channel steel 12 are connected with each other through the welded first steel beams 13. I.e. the outer gantry is square-frame shaped, seen from the front to the back.
The left side and the right side of the middle portal frame are respectively provided with a first left I-shaped steel 21 and a first right I-shaped steel 22 which are vertical. The 2 openings of the first left i-steel 21 face left and right respectively, the 2 openings of the first right i-steel 22 face left and right respectively, and the upper and lower ends of the first left i-steel 21 and the upper and lower ends of the first right i-steel 22 are connected by the welded second steel beam 23 correspondingly. That is, the center frame is shaped like a square frame when viewed from the front to the rear.
The left side and the right side of the inner gantry are respectively provided with a second left part I-steel 31 and a second right part I-steel 32 which are vertical. The 2 openings of the second left i-beam 31 face left and right respectively, the 2 openings of the second right i-beam 32 face left and right respectively, and the upper and lower ends of the second left i-beam 31 and the upper and lower ends of the second right i-beam 32 are connected by the welded third steel beam 33 correspondingly. That is, the inner door frame is square frame-shaped when viewed from the front to the rear.
The left channel steel 11 and the right channel steel 12 have the same specification; the first left I-beam 21, the first right I-beam 22, the second left I-beam 31 and the second right I-beam 32 have the same specification. That is, the sections of the left channel 11 and the right channel 12 are the same; the first left I-beam 21, the first right I-beam 22, the second left I-beam 31 and the second right I-beam 32 have the same section.
And the distance between the inner side surfaces of the two legs of the left channel steel 11 is not less than the distance between the outer side surfaces of the two legs of the first left I-steel 21, and 2 legs on the left side of the first left I-steel 21 are clamped between the two legs of the left channel steel 11. Preferably, the distance between the inner sides of the two legs of the left channel 11 refers to the average distance between the inner sides of the two legs of the left channel 11. The distance between the inner sides of the two legs of the right channel steel 12 is not less than the distance between the outer sides of the two legs of the first right I-steel 22, and 2 legs on the right side of the first right I-steel 22 are clamped between the two legs of the right channel steel 12. Also, preferably, the distance between the inner sides of the two legs of the right channel 12 refers to the average distance between the inner sides of the two legs of the right channel 12. The rear leg of the 2 left legs of the second left I-beam 31 is clamped between the 2 right legs of the first left I-beam 21; the rear leg of the 2 legs on the right side of the second right section h-bar 32 is clamped between the 2 legs on the left side of the first right section h-bar 22.
Obviously, for assembly, the first steel beam 13, the second steel beam 23, and the third steel beam 33 are preferably in a U shape with a front opening, as viewed from top to bottom.
In conclusion, the channel steel used by the outer door frame uses C-shaped channel steel with slightly larger leg spacing, the middle door frame and the inner door frame use I-shaped steel with the same model, the I-shaped steel (namely, the first left I-shaped steel and the first right I-shaped steel) of the middle door frame is contained in the channel steel (namely, the left channel steel and the right channel steel) of the outer door frame in a pairwise correspondence manner, the I-shaped steel (namely, the second left I-shaped steel and the second right I-shaped steel) of the inner door frame is staggered with the I-shaped steel of the middle door frame, the front side surface of the I-shaped steel of the inner door frame is flush with the front side surface of the channel steel of the outer door frame, and therefore the front suspension distance is reduced, and the cargo.
