Abstract
The utility model relates to a container, which discloses a bottom frame for a container which can be suitable for a telescopic trailer. The utility model comprises bottom lateral beams 5 which are positioned on both sides in the longitudinal direction and a group of bottom cross beams 6 which are mutually parallel and are vertically connected with the two bottom lateral beams. The utility model is characterized in that a local reinforcement part is arranged within the range of the length of the bottom frame. When a container of the bottom frame load and unload goods on a telescopic trailer, because the bottom frame which is positioned at the part of a telescopic segment of the trailer is reinforced, the safety and the service life of the container can be improved.
Description
Technical field
The utility model relates to freight container, is specifically related to a kind of chassis of container that is applicable to telescopic trailer (extendable chassis).
Technical background
The length dimension specification of most of freight container is a standard, and the most commonly used have 40 feet and 20 feet iso standard freight containers.Correspondingly, the trailer's length that is used for delivery container generally is 40 feet.
But in recent years, having occurred length specification in succession is 45 feet, 48 feet, 53 feet freight container.Transport the trailer of these non-ISO casees, length must become exclusive trail car above 40 feet.Like this, the transportation company trailer kind that must be equipped with can increase.And, because can not be general between the trailer, the freight volume of different case kinds is also unbalanced, thereby makes the trailer of transportation company the unbalanced of use occur.For Applicable scope and the commonality that improves trailer, in America and European market, a kind of trailer of adjustable in length has appearred, as shown in Figure 2.When receiving hour, can load and transport 40 feet and 20 forty equivalent unit 40s.When moving to when the longest, can load and transport 45 feet, 48 feet or 53 forty equivalent unit 40s.This telescopic trailer is with respect to the trailer of regular length, owing to using the more flexible extensive welcome that is subjected to.Also the safety of loading and transporting on trailer for freight container has brought hidden danger but simultaneously.
Shown in Fig. 2 a and Fig. 2 b, the underframe of telescopic trailer is provided with Collapsible structure 4.When being used to transport overproof length freight container, with the underframe elongation so that the total length of freight container be supported.But after the elongation of this trailer, some areal of support of its telescopic section 4 is lower than other parts, so just makes the freight container of putting thereon, and the bottom cross beam of its appropriate section can not get support.For the ISO freight container, partly or entirely bottom cross beam can not get supporting, and does not influence normal and transports safely.And, owing to pursue big internal volume, and make container bottom cross beam weak many than the ISO case for 48 feet and 53 feet inland container depots.Therefore, when transportation and lade, its end crossbeam must be supported on the longitudinal girder 9 of trailer.Obviously, during lade, owing to do not support the scope of a section very long (such as 5 feet) in, there is the possibility of being out of shape in the underframe of freight container to this freight container, has a strong impact on the safe in utilization and life-span of freight container on telescopic trailer.
The utility model content
The technical problems to be solved in the utility model is, a kind of freight container is provided, and makes it can be applicable to telescopic trailer, improves freight container safety in utilization and service life during handling goods on telescopic trailer.
Technical matters of the present utility model is to solve like this: a kind of chassis of container that is suitable for telescopic trailer (extendable chassis) comprises in the bottom side beams of vertical both sides and is vertically connected at one group of bottom cross beam that is parallel to each other between described two bottom side beams; It is characterized in that, in the length range of described underframe, be provided with a local reinforcing section; Described local reinforcing section comprises three continuous bottom cross beams at least.
According to the utility model, the bottom cross beam upper surface of described local reinforcing section, with adjacent other bottom cross beam upper surfaces in same horizontal surface.
According to the utility model, described local reinforcing section can be the bottom cross beam arranging density part closeer than other parts.
According to the utility model, the structure of described local reinforcing section can for, be provided with in this part and be no less than two longerons that the bottom cross beam of this part position is connected as a single entity, described longeron is distributed between two bottom side beams.
According to the utility model, described longeron can for the cross connection of at least one foundation crossbeam.
According to the utility model, the connection mode of longeron and bottom cross beam also can for: every longeron is connected between the two adjacent foundation crossbeams, and the longeron of same foundation crossbeam both sides is staggered mode and arranges.
Implement the chassis of container that the utility model provides, can strengthen the intensity of chassis of container, be applicable to the telescopic container trailer of length, can improve the anti-ability of destroying of chassis of container, prolong the service life of freight container corresponding to the trailer telescopic section.Below in conjunction with drawings and Examples the utility model is described in further detail.

The specific embodiment
The utility model chassis of container as shown in Figure 3 comprises in the bottom side beams 5 of vertical both sides and is vertically connected at one group of bottom cross beam that is parallel to each other 6 between described two bottom side beams; In the described chassis of container, be provided with a local reinforcing section 7.In the present embodiment, local reinforcing section 7 is the bottom cross beam arranging density part closeer than other parts.By the arrangement of local density bottom cross beam, the deadweight of freight container and cost increase few like this, but owing to make the intensity of key position obtain reinforcement, have increased its safety in utilization, also can increase the service life.During use, this local reinforcing section just in time is positioned on the flexible position of trailer.
Fig. 4 is the scheme drawing of another embodiment of the utility model chassis of container.The structure of local reinforcing section is in the present embodiment, is provided with the longeron 8 that the bottom cross beam with this part position is connected as a single entity in this part, and described longeron 8 is distributed between two bottom side beams 5.Longeron 8 generally is no less than two, and present embodiment is three.In the present embodiment, longeron 8 and 6 cross connections of a middle foundation crossbeam, the two ends of longeron 8 are connected with the sidepiece of the bottom cross beam of both sides respectively.
Longeron 8 also can adopt mode shown in Figure 5 with the connection mode of bottom cross beam 6, and promptly every longeron 8 is connected between the two adjacent foundation crossbeams 6, and the longeron of same foundation crossbeam both sides is staggered mode and arranges.
As shown in Figure 6, the local reinforcing section in the utility model chassis of container also can improve intensity by adopt the bottom cross beam 6 of suitable cross sectional shape in this part, as being shown in following any one: C type, I type, L type, Ω type.By adopting such cross sectional shape, strengthen the bottom cross beam cross sectional moment of inertia, thereby improve the bending strength of this part.Longeron 8 also can adopt cross sectional shape listed above.
The purpose of this utility model also can be used the bottom cross beam of high strength material by at the local reinforcing section of need, makes intensity higher realize of the material of this place's bottom cross beam than the bottom cross beam of other parts.If use Q235 (GB700-88) as the underframe base portion, the bottom cross beam of local reinforcing section can adopt the 16Mn high steel of Material Strength such as (GB1591-88).Play the longeron of local booster action, also can adopt the higher steel of this intensity.
