Brief Description of the Drawings

The drawing shows a vehicle for transportation of trucks and self-propelled machinery, a general view.

The implementation of the invention

A vehicle for transporting trucks and self-propelled vehicles contains a frame 1 made of two trusses reinforced with trusses (not shown) of the spars 2 connected by transverse beams 3 for a zigzag deck 4 with guide tracks 5, which are mounted in the seat part of the frame 1 with a lift, and in the back - with a slope, a hydraulic system 6, entrance ramps 7, support 8 and chassis 9 parts.

In the rear part of the frame 1, a movable platform 10 with a slope repetition is installed with rollers 11 in the lower part with the possibility of moving in the horizontal and vertical plane in the guides 12 installed under the deck 4. On the sides of the platform 10, levers 13 are pivotally mounted with the possibility of lifting the upper part platforms 10, the middle part of which is pivotally connected to the rods of hydraulic cylinders 14 of the hydraulic system 6, and the lower one with the frame 1.

In the upper part of the platform 10, on the sides, it is provided with folding adjustable rods 15 of the transport position, and on the platform 10 there are mounted wheel stops 16, and the guide tracks 5 are raised raised in front of the platform 10 to its level.

Entrance ladders 7 are pivotally mounted on the rear transverse beam 3, each of which is provided on the inside with a spring 17, which is installed to facilitate lifting and lowering, and with an external folding hinged rod 15 for fixing the transport position. The spring 17 is mounted on a guide rod 18, the lower end of which with a stop (not shown in the drawing) is pivotally mounted on the bracket 19 of the rear transverse beam 3, forming an angle with the entry ladder 7, and the top passes with the possibility of compression and extension of the spring 17 through the hole 20 of the stop installed on the entrance ladder 7 when transferring each ladder to the loading, and then to the transport position.

In the rear part of the frame 1 under the deck 4 there are additional supports 21 of the loading position with the possibility of lowering and lifting using the hydraulic system 6.

A vehicle for transporting trucks and self-propelled machinery is operated as follows.

A vehicle containing a supporting 8 and a running gear 9 is loaded as follows (loading option with three tractor units).

At the entry ramps 7, the rods 15 are unlocked and tilted and each ramp 7 is lowered one at a time, with a spring 17 mounted on the guide rod 18, the lower end of which rotates in the hinge of the bracket 19, and the upper end moves through the hole 20 of the limiter, works for compression.

Using the hydraulic system 6, the additional supports 21 are lowered, installed in the rear of the frame 1 under the deck 4.

On the platform 10, the wheel stops 16 are lowered.

The 1st car reverses along the entry ramps 7 of the lowered platform 10, the zigzag deck 4, mounted on the side members 2 with transverse beams 3, onto the guide tracks 5, which are lifted in the seat part of the frame 1.

The 2nd car enters the vehicle in the usual way, similar to the first with a minimum clearance between the cars. The upper part of the platform 10 with the help of levers 13 and the rods of the hydraulic cylinders 14 is lifted and mounted above the chassis of the 2nd a / m, while the lower part of the platform 10 with rollers 11 moves along the rails 12. The hinged rods 15 are mounted and fixed. The stops on the platform 10 are raised wheels 16.

The 3rd car backs up along the entry ramps 7 onto the platform 10 to the wheel stops 16.

Entrance ladders 7 are lifted and fixed in the transport position by the rods 15. Additional supports 21 are lifted using the hydraulic system 6.

All cars are additionally fixed with removable stops (not shown in the drawing).

Unloading in the reverse order.

Thus, the use of a mobile platform 10 allows you to increase the number of truck tractors being transported from two to three, which increases the profitability of transportation when using a vehicle, while this vehicle can also be used to transport various self-propelled equipment (construction vehicles - rollers) without using a mobile platform 10, which is versatility.

Additional support 21 of the loading position is used when loading the vehicle for stability, since the loaded equipment has a significant mass, as well as levers pivotally mounted on the sides of the platform, and folding arms fix the transport position with the possibility of regulation.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- simplification of loading and unloading;

- increase in the number of transported equipment;

- increase operational safety;

- reliability of fastening;

- stability during loading and unloading.
