The invention relates to loading and unloading and transporting tons of large-sized oversized cargo, in particular to vehicles such as semi-trailers for transportation, such as block boxes for the construction of oil and gas companies.

The closest technical solution to the invention is a semi-trailer, comprising a frame with horizontal and inclined guides rigidly mounted on its front part, a platform with roller supports and rear guides, as well as a linear motion drive 1.

A disadvantage of the known device is that it requires a drive of considerable power, since in the initial stage the platform is pulled out at a minimum and the tilt takes place immediately to a significant angle, which requires the use of a powerful drive.

The aim of the invention is to reduce the energy consumption for moving the moving frame elements and reduce the consumption of materials.

To achieve this goal, in the semi-trailer for transportation of heavy-weight heavy goods, containing a frame with horizontal and inclined guides rigidly fixed on its front part, a platform with roller supports and rear guides, as well as a linear movement drive, the platform is made in the form of two hinges interconnected sections with separate roller supports, with the front section roller bearing located in horizontal rails, the rear section roller bearing located near the 1-hinged Connections sections with possibility of reacting se with inclined nagfavl yuschimi frame and the rear part of the platform mounted guide and abutment) with the Interaction of carrying rollers mounted at the rear of the frame.

FIG. 1 shows a semitrailer in the graded position, side view; in fig. 2-4 - then; at different stages of unloading; in fig. 5 shows the node I in FIG. one; in fig. 6 is a view A of FIG. one; in fig. 7 - section bb pa fig. five; in fig. 8 is a section bb of FIG. five.

On the frame 1 of the semi-trailer there is a hydro-cylinder 2 for the drive of the loading platform. P1TOK 4 which through ti gi 5 is connected to

a platform section 6, arnirno connected with the second section 7, provided with a stop 8, cooperating with roller bearings 9 mounted on frame I.

Sections 6 and 7 are provided at the ends facing the trap 10, respectively with rollers 11 and 12. Horizontal guides 13 for rollers 11 and inclined 14 for rollers 12 are mounted on the frame. Horizontal guides 12 are located between the inclined guides 14 and in parallel last one. The load 15 is mounted on the load platform 3.

The device works as follows.

In the transport position, the semi-loaded cargo platform 3 is in the E leftmost position, the cargo 15 lies on both sections 6 and 7. When unloaded, the hydraulic cylinder 2 turns on and the platform 3 moves to the right, the rollers 11 roll along the guides 13, and the rollers 12 fall on the inclined guides 14, which causes the platform 3 to fracture in place of the cross-section of sections 6 and 7. Upon further movement of the rod 4 of the hydraulic cylinder 2, section 7 is tilted with a load 15, section 6 plays the role of a supporting lever. When the section 7 is subsequently tilted, the rollers 12 are detached from the inclined guides, the stop 8 comes into contact with the roller supports 9. In this case, the end of the platform 3 touches the ground and the load 15 slides away. The semi-trailer leaves to the left until the load is completely on the ground.

For loading, the cargo is installed by special means (not shown) on the platform section 7 and by moving the cylinder 4 of the hydraulic cylinder 2 to the left, the platform is unfolded and returned to the transport position.

The use of the proposed semi-trailer construction will allow replacing the well-known more complex structures, in which several hydraulic cylinders are used to move the cargo platform, as well as devices requiring a powerful drive, made with telescopic sliding platforms and a retaining lever. In addition, the use of the proposed design will increase the load capacity of the semitrailer by using a drive of much lower power and, therefore, of less weight.
