Abstract
The utility model relates to a longitudinal beam of a trailer and a trailer comprising same. The longitudinal beam of the trailer comprises an upper wing plate, a lower wing plate and a web plate fixedly connected between the upper wing plate and the lower wing plate, wherein a groove is arranged on the upper surface and/or the lower surface of at least one of the upper wing plate and the lower wing plate, and is distributed in the length direction of the groove. The longitudinal beam of the trailer effectively reduces the dead weight of the longitudinal beam on the basis of guaranteed strength, further reduces the dead weight of the entire trailer, saves oil consumption, simultaneously reduces waste gas generation, and protects environment.
Description
Technical field
The utility model relates to trailer, and is especially relevant with the girder work of trailer.
Background technology
Longeron is the main load-supporting part of cargo trailer, and it vertically is arranged on the underframe of trailer, and as shown in Figure 1, longeron comprises: upper flange 11, lower wing plate 13 and be connected web 12 between the upper and lower wing plate 11,13.Upper and lower wing plate 11,13 adopts the band steel usually, thickness is that 10mm-16mm does not wait, the straight plate structure of this entire body equal thickness has also produced some weight more than needed when satisfying intensity, cause the longeron deadweight bigger, thereby cause car load deadweight excessive, this disagrees satisfying the requirement that reduces the deadweight of trailer under the situation of load bearing requirements as far as possible for the laws and regulations that adapt to current state treatment and overload with the user.
Summary of the invention
The technical problems to be solved in the utility model is: under the prerequisite that guarantees longeron intensity, effectively reduce the longeron deadweight, and then reduce the car load deadweight, cut down the consumption of energy, reduce waste gas, the protection environment.
For solving the problems of the technologies described above, the utility model provides a kind of trailer longeron, comprise: upper flange, lower wing plate and be fixedly connected on web between the upper and lower wing plate, in described upper flange and the lower wing plate one of at least upper surface and/or the lower surface setting along himself length direction grooves distributed.
Described trailer longeron, wherein, described groove connects the length direction of described upper flange or lower wing plate.
Described trailer longeron, wherein, described groove is positioned at the middle part of the Width of described upper flange or lower wing plate.
For solving the problems of the technologies described above, the utility model also provides a kind of trailer, comprising: underframe and the two above-mentioned trailer longerons along the setting of length over end sills direction.
Useful technique effect of the present utility model is: because the upper flange and/or the lower wing plate of longeron are provided with groove, so, the deadweight that has alleviated longeron; and then the car load that has reduced trailer is conducted oneself with dignity; and the reduction of trailer car load deadweight can effectively reduce oil consumption, reduces waste gas and produces, the protection environment.And through facts have proved of contriver, though the deadweight of the longeron of this kind structure has reduced, intensity lacks not to be had therefore to weaken, and on the contrary, has also strengthened resistance to bending and lear energy to a certain extent.

Fig. 1 is the structural representation of longeron in the prior art;
Fig. 2 is the structural representation of first embodiment of longeron of the present utility model;
Fig. 3 is that longeron shown in Figure 2 is arranged on the structural representation on the trailer underframe;
Fig. 4 is for second embodiment of longeron of the present utility model and be arranged on structural representation on the trailer underframe;
Fig. 5 is for the 3rd embodiment of longeron of the present utility model and be arranged on structural representation on the trailer underframe.
The specific embodiment
Consult Fig. 2, it is the structural representation of the utility model longeron 1 first embodiment, longeron 1 comprises: upper flange 11, lower wing plate 13 and be fixedly connected on web 12 between the upper and lower wing plate 11,13, lower surface at lower wing plate 13 is provided with a groove 131, and groove 131 distributes along the length direction of lower wing plate 13.Groove 131 can connect lower wing plate 13 also can not connect lower wing plate 13, preferred: groove 131 connects lower wing plate 13 along the length direction of lower wing plate 13, to simplify the implementing process of lower wing plate 13, makes things convenient for production and processing.Groove 131 is positioned at the middle part of lower wing plate 13 Widths, thus the each several part that makes lower wing plate 13 all with respect to its longitudinal central axis line or laterally the axis be centrosymmetric, balance lower wing plate 13 each several parts stressed, the service life of having improved lower wing plate 13.
Consult Fig. 3, it is that longeron 1 shown in Figure 2 is arranged on the structural representation on the trailer underframe, as shown in the figure, underframe be vertically arranged with longeron 1 and side bar 2, being horizontally arranged with of underframe runs through beam 3 and main beam 4, side bar 2 is positioned at the lateral edges of underframe, run through beam 3 and run through the whole Width that is arranged on underframe, longeron 1 roughly is positioned at the middle part of Width of underframe shouldering main load-bearing effect, and base plate 5 is laid on longeron 1, side bar 2, runs through the top of beam 3 and main beam 4 to form the loading platform.Because the lower wing plate 13 of longeron 1 is provided with groove 131, so, alleviated the deadweight of longeron 1, and then reduced the car load deadweight of trailer, and the reduction of trailer car load deadweight has reduced oil consumption effectively, has reduced the waste gas generation, has protected environment.And through facts have proved of contriver, though longeron 1 deadweight of this kind structure has reduced, therefore intensity do not weaken, and on the contrary, also strengthened resistance to bending and lear energy to a certain extent.
Fig. 4 shows the structural representation of longeron 1 second embodiment, in the present embodiment, longeron 1a not only is provided with groove 131 at the lower surface of lower wing plate 13, also the upper surface at upper flange 11 is provided with groove 111, groove 111,131 can connect upper and lower wing plate 11,13 along the length direction of upper and lower wing plate 11,13, also can not connect upper and lower wing plate 11,13, preferred: groove 111,131 connects upper and lower wing plate 11,13.Longeron 1a compares the longeron 1 of above-mentioned first embodiment in the present embodiment, and its deadweight is littler.
Fig. 5 shows the structural representation of longeron 1 the 3rd embodiment, in the present embodiment, the upper and lower surface of the upper flange of longeron 1b is provided with groove 111, the upper and lower surface of lower wing plate 13 also is provided with groove 131, groove 111,131 can connect upper and lower wing plate 11,13 along the length direction of upper and lower wing plate 11,13, also can not connect upper and lower wing plate 11,13, preferred: groove 111,131 connects upper and lower wing plate 11,13.Longeron 1b is littler than the deadweight of the longeron 1 of above-mentioned first, second embodiment, 1a in the present embodiment.
In sum; in the upper flange 11 of longeron 1,1a, 1b and lower wing plate 13 one of at least upper surface and/or the lower surface setting along himself length direction grooves distributed 111,131; make longeron 1,1a, 1b when guaranteeing its intensity, effectively reduce its deadweight; and then reduce car load and conduct oneself with dignity; save oil consumption; reduce waste gas and produce, the protection environment.
The above only is a preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, and the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content have been done changes, and all is included in the protection domain of the present utility model.
