Frame-type semi-trailer

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, ...

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 specification, which makes it necessary to design a unique container for the transportation of the semi-trailer instead of using a general-purpose container. 20`, 40` or 53` containers, and because container ships are designed according to the specifications of standard containers, even if a unique container is used, although the problem of lifting can be solved, the semi-trailer cannot be placed on the In the cabin and cannot be placed in rows continuously, resulting in low transportation efficiency
