Abstract
The utility model discloses a semi-trailer groove type longitudinal beam and a semi-trailer frame utilizing the same. The cross section of the semi-trailer groove type longitudinal beam is a vertical groove type structure, the width of the top of the longitudinal beam is equal to that of the bottom of the longitudinal beam or the widths of the tops of all the longitudinal beams are identical, the width of the front portion of a gooseneck portion of the bottom of the longitudinal beam is larger than the width of the top of the longitudinal beam, the size of the rear portion of the gooseneck portion is equal to the width of the top, and the gooseneck portion is wide in front portion and narrow in rear portion and transits gradually. The semi-trailer frame comprises two semi-trailer groove type longitudinal beams which are arranged in parallel, and the two longitudinal beams are arranged oppositely with outward groove openings. The utility model is simple in structure and easy in manufacturing, increases production efficiency, reduces labor intensity of workers, reduces production cost and increases profits of manufacturers.
Description
Technical field
The utility model belongs to the superimposed trailer manufacturing technology field of large-scale transport trolley, relates in particular to a kind of superimposed trailer grooved longeron and uses the semi-trailer frame of this longeron.
Background technology
At present, semi-trailer frame is general all to be formed by two longerons and some crossbeam manufacturings being located between two longerons, wherein two longerons generally all use the three block length bar steel plates crossbeam of cross-sectional plane for " worker " font that be welded, this manufacturing course of longeron is loaded down with trivial details, technology bothers, labour intensity is big, production efficiency is low, particularly when three block length bar steel plates weld, need welding four roads, yielding distortion, and steel plate is thicker, weight is bigger, increase the overall weight of vehicle frame, strengthened manufacturing cost virtually.
The utility model content
The utility model is in order to solve weak point of the prior art, provides that a kind of manufacturing process is simple, production efficiency is high, lightweight superimposed trailer grooved longeron and use the semi-trailer frame of this longeron.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: superimposed trailer grooved longeron, the cross-sectional plane of described longeron are vertical trench structure.Adopt this structure, two longerons can disposable punch forming, and manufacturing process is simple, has saved this road program of welding, makes longeron straight non-warping, and weight saving, and productive costs reduces.
Described longeron top and bottom width dimensions is equal, more saving in material.
Described longeron top width unanimity, bottom gooseneck place previous section width dimensions are greater than the top width size, and gooseneck place aft section size equates with the top width size, the front wide and rear narrow progressively transition of gooseneck place size, and this structure can be more quick in the time of punching press.
Semi-trailer frame, it comprises two above-mentioned superimposed trailer grooved longerons that be arranged in parallel, is provided with some crossbeams between two longerons, the cross-sectional plane of described two longerons is vertical trench structure.
Described longeron top and bottom width dimensions equates.
Described longeron top width unanimity, bottom gooseneck place previous section width dimensions are greater than the top width size, and gooseneck place aft section size equates with the top width size, the front wide and rear narrow progressively transition of gooseneck place size.
Described two longerons are back to setting, and notch is outside.
Adopt said structure, the utility model is simple in structure, easy to manufacture, improved production efficiency, alleviated working strength of workers, reduced productive costs, increased the profit of manufacturer.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, superimposed trailer grooved longeron 1 of the present utility model, the cross-sectional plane of longeron 1 is vertical trench structure, by the punch forming of steel plate overall time, there is one section upwards part of transition formation likeness in form gooseneck 4 bottom on the direction from back to front.
Superimposed trailer grooved longeron 1 embodiment one: with reference to Fig. 1 and Fig. 3, the top and bottom width dimensions of longeron 1 equates.
Superimposed trailer grooved longeron 1 embodiment two: with reference to Fig. 2 and Fig. 3, longeron 1 top width unanimity, bottom gooseneck 4 place's previous section width dimensions are greater than the top width size, and gooseneck 4 place's aft section sizes equate with the top width size, the front wide and rear narrow progressively transition of gooseneck 4 place's sizes.
As Fig. 4, Fig. 5 and shown in Figure 6, semi-trailer frame of the present utility model, comprise the longeron 1-1 and the longeron 1-2 that be arranged in parallel, the cross-sectional plane of longeron 1-1 and longeron 1-2 is vertical trench structure, welding is provided with some crossbeams 3 between longeron 1-1 and the longeron 1-2, back to setting, notch is outside by the punch forming of steel plate overall time for longeron 1-1 and longeron 1-2, and there is one section upwards part of transition formation likeness in form gooseneck longeron 1-1 and longeron 1-2 bottom on the direction from back to front.
Semi-trailer frame embodiment one: with reference to Fig. 4 and Fig. 6, the top and bottom width dimensions of longeron 1-1 and longeron 1-2 equates.
Semi-trailer frame embodiment two: with reference to Fig. 5 and Fig. 6, longeron 1-1 is consistent with longeron 1-2 top width, gooseneck place, bottom 4 previous section width dimensions are greater than the top width size, and gooseneck place 4 aft section sizes equate with the top width size, the front wide and rear narrow progressively transition of gooseneck place 4 sizes.
