Problems solved by technology

At present, there are two common methods in sea transportation. One is to use bulk carriers for transportation. The cost of this transportation method is relatively high, which will lead to an increase in the total cost of semi-trailer production; the other is to use container ships for transportation. , because the semi-trailer of the same specification is longer than the container, for example, the 20` and 40` semi-trailers are slightly longer than the 20` and 40` containers of the same specif

Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] As shown in Figure 2, a skeleton type semi-trailer 2 includes a gooseneck beam frame 20 located at its front end for connecting with the tractor, a beam frame body 21 for carrying goods, and a frame body 21 arranged on the frame body. The wheel 22 at the lower part of the rear end and the retractable supporting leg 23 arranged at the lower part of the front end of the beam frame body 21 . This car is supported by wheel 22 and retractable support leg 23 when parking, and during use, the traction pin 201 that will be positioned at gooseneck beam frame 20 bottoms is hung in the traction seat of tractor, and contraction support leg 12 gets final product.

[0036] Such as image 3 The beam frame body 21 shown includes a front beam frame 24 at its front end and a rear end beam frame 25 at its rear end.

[0037] The front beam frame ...

Abstract

The invention discloses a frame type semi-trailer, which comprises a beam frame body for carrying goods, a gooseneck beam frame for connecting a towing vehicle and wheels arranged on the lower part of the rear end of the beam frame body, wherein the beam frame body comprises a front end beam frame and a rear end beam frame which can slide longitudinally and oppositely; the front end beam frame comprises front end beams which are positioned on two sides of the front end beam frame and are arranged longitudinally; the rear end beam frame comprises rear end beams which are positioned on two sides of the rear end beam frame and are arranged longitudinally; the front section of the rear end beam is provided with a slide chute; the whole front end beam is of a linear type; the tail section of the front end beam is inserted into the slide chute along the longitudinal direction, and is converted between the elongated position and the shortening position; and a locking mechanism which can lock the tail section of the front end beam and the front section of the rear end beam in the elongated position or the shortening position is arranged between the rail section of the front end beam and the front section of the rear end beam. The frame type semi-trailer has the advantages that the structure is simple and reasonable, and the operation and use are convenient, and the semi-trailer can be loaded into a container by shortening the overall length of the semi-trailer, thereby improving the transportation efficiency.

Description

(1) Technical field [0001] The invention relates to a semi-trailer with driven ground wheels, in particular to a frame-type semi-trailer for carrying containers. (2) Background technology [0002] In the field of transportation, there is a device called a semi-trailer, which is a vehicle for inland long-distance dry cargo transportation widely used in Europe and the United States. [0003] The most commonly used semi-trailer is a skeleton semi-trailer (without tops) for carrying containers. As shown in Figure 1, this skeleton semi-trailer mainly includes a beam frame with a gooseneck-like front end (goose neck) 10. Set the wheel 11 at the lower part of the rear end of the beam frame body, and the retractable outrigger 12 arranged at the lower part of the front end of the beam frame body, and a traction pin (not shown) is also provided at the lower part of the front end of the beam frame body; when in use, hang the traction pin into the traction In the traction seat of car, ...
