Abstract
The utility model belongs to airport lifting device field discloses a lifting mechanism big arm section bar structure, two fixed cross supports on the frame, and the support is including lifting big arm, and its characterized in that lifts big arm both ends and is the arc structure, lifts and has seted up a plurality of through-holes on the big arm. The volume is obviously reduced, and the requirement of operation intensity is met.
Description
The technical field is as follows:
the utility model belongs to airport lifting device field, concretely relates to lifting mechanism forearm section bar structure.
Background art:
the existing trip of people is mostly realized by adopting airplane flight, a large-arm section bar is a main section bar of a lifting mechanism of airport equipment, a fork frame type structure formed by the section bars is fixed on a frame, and the opening angle of the fork frame type structure is changed by utilizing an oil cylinder so as to achieve the lifting effect. The box on the large arm and the load thereof have relatively large weight, so the requirements on the strength and the stability of the large arm are relatively high. As shown in fig. 1 and 2, the existing large arm section bar is generally of a hollow structure, and has unreasonable structure and poor strength, so that the lifting requirements of airports are difficult to load.
The utility model has the following contents:
the utility model aims at overcoming prior art's defect, provides a lifting mechanism forearm section bar structure, relates to lifting equipment, specifically is a structure based on section bar structure's change self is strengthened, makes the section bar of lifting usefulness at the apparent reduction in volume, and reaches the requirement of operation intensity.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a lifting mechanism big arm section bar structure, two crossing supports of fixing on the frame, the support is including lifting big arm 1, its characterized in that, lifts big arm both ends and is the arc structure, lifts to have seted up a plurality of through-holes on the big arm.
Preferably, the lifting boom 1 is of an integral middle-shaped structure and is composed of flat plates with channel steel fixedly welded on both sides.
Preferably, the flat sheet width is greater than the channel width.
Preferably, the channel steel is a bent groove type plate.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model adopts the material to be folded into the channel steel type, and the structure is utilized to strengthen the first step; two bending groove type panels are fixed on a flat plate, and the integral structural strength is further improved.
Drawings
FIG. 1 shows a normal profile used in the past;
figure 2 is a cross-sectional view of a normal profile.
FIG. 3 is a plan view of the boom section of the lifting mechanism of the present invention;
FIG. 4 is a sectional view of a boom section of the lifting mechanism of the present invention;
Detailed Description
For a better explanation of the invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
The embodiment is shown in fig. 3-4, a profile structure of a large arm of a lifting mechanism, which comprises two crossed brackets fixed on a frame, wherein each bracket comprises a lifting large arm 1, two ends of each lifting large arm are of arc structures, and a plurality of through holes are formed in each lifting large arm. The lifting boom 1 is of an integral middle-shaped structure and is composed of flat plates with channel steel fixedly welded on two sides. The width of the flat plate is larger than that of the channel steel, and the channel steel is a bent groove type plate.
This novel combined section bar self intensity, in addition the reinforcing combination welding of muscle board-like for holistic intensity, rigidity obtain promoting.
The above description is only for the purpose of illustrating embodiments of the present invention and should not be taken as limiting the invention, and any modifications, equivalents, improvements and the like made by those skilled in the art within the spirit and principle of the present invention should be included in the scope of the present invention.
Claims (4)
