Description

The invention relates to roadless vehicles, in particular, to long-haul road trains.

The purpose of the invention is to increase productivity.

FIG. 1 shows a road train farm truck, side view, transport position; in fig. 2 - the same at the time of unloading; in fig. 3 - the same, top view; in fig. 4 is a section A-A in FIG. 2

Shifting as they go down, they take a horizontal position, which allows the fingers 10 to freely exit from the grippers 8.

After the installation of the cassette 9 with the load on the ground and the release of the undercarriage 5, the truck leaves forward. Before the return flight, the driver plunges an empty cassette 9 onto the semi-trailer.

The road train contains a tacho 1 and a semi-tO so that the cassette 9 falls between the branches of the scraper with the load-carrying sliding U-image-moving U-shaped frame of the semi-trailer to the frame consisting of the front section 2, the stop of the fingers 10 in the front wall of the mouth dropping onto the fifth wheel hitch assist 8. The driver then again slows down the tacho 1 of the insert 3 and the rear section 4, lives the undercarriage 5 and turns on the hydraulic trolley 5, which rests against the undercarriage 5. 1 In the cavity of the front 2 and rear 4 seconds - feeds back. This reduces the length of the sliding frame of the semi-trailer, and the approach of the lower points of attachment of the levers 7 causes the grippers 8 to rise together with the load-bearing element 9 into the transport position, with the walls of the throat grips 8,

of the sliding frame are located and pivotally fixed at one end of four hydraulic cylinders b, which are oppositely pivotally attached to intermediate element 3. To the upper part of the front section 2, intermediate element 3 and the rear section 4 of the sliding frame are attached by hinges top of the pair and fitted with grippers 8, motionless

turning together with the front lever 7, fix the load.

The stoppers 11 placed on the element 9 fit into the grooves of the lower front 2 and rear 4 frame sections, both frame sections

attached to the front arms 7. For 25 stops m. Stopping the sliding sections for placing cargo between the frame sections has a load-bearing element 9, in the upper part of which fingers 10 are fixed, and in the lower part, on brackets, stoppers 11 for securing the sliding frame in the transverse direction . To ensure that the load-carrying element 9 is placed between the frame sections when the vehicle is moving in reverse, the levers 7 of the rear pairs can be made shorter than the levers 7 of the front pairs, or, in the shifted position, are made, for example, by hydraulic stop.

Claims (1)

Invention Formula A vehicle containing a tacho, semi-trailer with a frame made of two sections movably interconnected by means of an intermediate element and a lifting mechanism, characterized in that, in order to improve performance The position between the attachment points of the rear 35 labor, the lifting mechanism made in the form of pairs of levers to the frame must be greater than the corresponding distance of the front pairs of levers. Accordingly, the fingers 10 are fixed in the front and rear parts of the element 9 at different heights. 40 The device works as follows. After the cargo has been delivered to the object, the driver slows down the undercarriage 5 and, by turning on the hydraulic cylinders 6 for expansion, moves the speed sensor 1 forward in the direction of travel. At the same time, the sliding U-45 frame extends, which causes an increase in the distance between the points of attachment of the levers 7 and, as a result, the lowering of the grips 8 to the lower position, and the element 9 to the ground level, and arms, the upper ends of which are hingedly and pairwise connected to each other; the specified ends are hingedly connectable to the upper ends of the brackets, the lower ends of which are rigidly fixed on the load bearing support located between the frame sections and made movable in a vertical direction. m direction, and the lower ends of the arms are pivotally connected to the sections joined to them and the intermediate frame element, while the frame sections are connected to one ends of the horizontal hydraulic cylinders. in, other ends which are connected to the intermediate frame element. Shifting as they go down, they take a horizontal position, which allows the fingers 10 to freely exit from the grippers 8. After the installation of the cassette 9 with the load on the ground and the release of the undercarriage 5, the truck leaves forward. Before the return flight, the driver plunges an empty cassette 9 onto the semi-trailer. so that the cassette 9 gets between the branches of the mobile U-shaped frame of the semi-trailer up to the stop of the fingers 10 into the front wall of the grips 8. Then the driver again brakes the undercarriage 5 and switches on the hydraulic cylinders 6 for displacement, and t gives back. This reduces the length of the sliding frame of the semi-trailer, and the approach of the lower points of attachment of the levers 7 causes the grippers 8 to rise together with the load-bearing element 9 into the transport position, with the walls of the throat grips 8, so that the cassette 9 gets between the branches of the mobile U-shaped frame of the semi-trailer up to the stop of the fingers 10 into the front wall of the grips 8. Then the driver again brakes the undercarriage 5 and switches on the hydraulic cylinders 6 for displacement, and t gives back. This reduces the length of the sliding frame of the semi-trailer, and the approach of the lower points of attachment of the levers 7 causes the grippers 8 to rise together with the load-bearing element 9 into the transport position, with the walls of the throat grips 8, turning together with the front lever 7, fix the load. The stoppers 11 placed on the element 9 fit into the grooves of the lower front 2 and rear 4 frame sections, both frame sections stopper t. Locking sections sliding stopper t. Locking sections sliding the frames in the shifted position are produced, for example, by hydroscopes. Invention Formula A vehicle containing a tacho, semi-trailer with a frame made of two sections movably interconnected by means of an intermediate element and a lifting mechanism, characterized in that, in order to improve performance labor, the lifting mechanism is made in the form labor, the lifting mechanism is made in the form arms, the upper ends of which are hingedly and pairwise connected to each other; the specified ends are hingedly connectable to the upper ends of the brackets, the lower ends of which are rigidly fixed on the load bearing support located between the frame sections and made movable in a vertical direction. m direction, and the lower ends of the arms are pivotally connected to the sections joined to them and the intermediate frame element, while the frame sections are connected to one ends of the horizontal hydraulic cylinders. in, other ends which are connected to the intermediate frame element. and . u.
