Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] refer to figure 1 , figure 2 , which is a structural schematic diagram of the first embodiment of the segmented main beam of the present invention. In this embodiment, the segmented main beam 1 is to cut off the existing integrated main beam at a distance of 11000 mm to 12000 mm from the front end of the chassis The two parts are detachably connected by a connecting structure, which includes: a first part 11, a second part 12 and a connecting part 13, and the first and second parts 11 and 12 each include an upper wing Plates 111 , 121 , lower wings 112 , 122 and a web 113 , 123 vertically connected between the upper and lower wings 111 , 121 , 112 , 122 . The connecting part 13 detachably connects the first and second parts 11, 12 together, so that the segmented main girder 1 can be cut into two sections in the length direction and loaded into stand...

Abstract

The invention provides a sectional-type main beam and a semitrailer underframe with the same. The sectional-type main beam comprises a first part, a second part and a connecting part for detachably connecting the first part with the second part, wherein, the first part and the second part respectively comprise an upper wing plate, a lower wing plate and a web plate which is vertically connected between the upper wing plate and the lower wing plate. In the invention, the sectional-type main beam and the semitrailer underframe with the main beam can be loaded in a standard container in sections for transport and riveted after reaching a destination, thus effectively solving the problem that the semitrailer underframe is transported through the standard shipping container, and improving the transportation efficiency.

Description

technical field [0001] The invention relates to a semi-trailer, in particular to a beam structure on the bottom frame of the semi-trailer. Background technique [0002] The semi-trailer mainly includes: an underframe, a supporting device installed at the front of the underframe, and a running mechanism installed at the rear of the underframe (including tires, rims, axles, suspensions and brakes, etc.), and the underframe includes: respectively arranged on the front , a front crossbeam and a rear crossbeam at the rear end, two side beams arranged on both sides, two main beams arranged along the length direction, and multiple crossbeams arranged along the width direction. The main beam is the main load-bearing mechanism of the semi-trailer, which runs through the entire length of the underframe. Due to the limitation of the size of the standard shipping container and the overall size of the underframe, the underframe cannot be transported in a standard shipping container, but ...
