The utility model relates to transport engineering, mainly to self-propelled self-loading loaders-dump trucks.

A self-loading vehicle is known comprising a tractor connected to a towing hitch with a trailer, a crane comprising a column with a drive rotatable around a vertical axis mounted on a tractor, an articulated boom mounted on the column with a possibility of rotation in a vertical plane, and a load gripping device mounted on the arrow . Moreover, the center of rotation of the column is located on a vertical line passing through the center of rotation of the hitch, and on the longitudinal axis of the tractor (see USSR AS 1594016, IPC 5 V 60 P 1/54, 6.35 / 90).

The closest set of essential features to the claimed technical solution is a vehicle with a device for self-loading and self-unloading, containing a self-propelled chassis with a cab, the frame of which is made of two longitudinally connected longitudinal members, a platform (body), articulated with a possibility of rotation with a drive in a vertical plane, a column mounted on a frame between the rear wall of the cab and the front wall of the platform in a niche with the possibility of turning the hydraulic cylinder horizontally of the natural plane, a lifting boom mounted on the column with the possibility of rotation in the vertical plane by means of a hydraulic cylinder, a handle on the end of which is pivotally mounted with the possibility of turning by hydraulic cylinders in the vertical plane, a gripping body in the form of a bucket and hydraulic control system of hydraulic cylinder 1i (see RF patent 208S631, IPC 6 B 60 P 1 / 48.1 / 54, 6.18 / 97).

The known device is not safe enough, since in the inoperative position, the load gripping body lies freely on top of the load on the platform, and the platform does not have a sufficiently reliable fixation when it is tilted.

The task was to ensure the safe operation of the vehicle with devices for self-loading and self-unloading.

The problem is solved due to the fact that in a vehicle with devices for self-loading and self-unloading, which contains a self-propelled chassis with a cab, the frame of which is made of two longitudinal longitudinal members rigidly interconnected, a platform articulated with the possibility of rotation by the drive in a vertical plane, a column, mounted on a frame between the rear wall of the cab and the front wall of the platform with the possibility of turning the hydraulic cylinder in a horizontal plane, a lifting boom mounted on columns f with the possibility of rotation in the vertical plane by means of a hydraulic cylinder, a handle at the end of which a load-gripping body is pivotally rotated by hydraulic cylinders in the vertical plane, and the hydraulic control system of the hydraulic cylinders, the column is installed at a certain distance from the front base of the car, and the frame is equipped with a subframe mounted on it with the help of brackets, the platform is mounted on a subframe and is equipped with a support rigidly fixed to it, having a bracket and a fixing device for loads In order to limit the tilt angle of the platform, the vehicle is equipped with a cable, which is attached at one end to the subframe and the other to the platform, and the column is installed behind the cab at a distance of 1/3 1/4 from the front base of the vehicle .

- 2 The analysis of the prior art, including searching for patent and scientific and technical sources of information, made it possible to establish that an analogue characterized by and identical to all the essential features of the claimed technical solution was not found. The determination from the list of identified analogues of the closest in the set of essential features of the prototype allowed us to establish a set of distinctive features that are significant in relation to the technical result in the claimed technical solution, set forth in the formula of the utility model. Therefore, the claimed technical solution meets the condition of novelty.

The proposed technical solution is illustrated by drawings, which depict a vehicle with devices for self-loading and self-unloading:

figure 1 is a side view;

figure 2 - view a in figure 1.

A vehicle with devices for self-loading and self-unloading comprises a self-propelled automobile chassis 1, a dumper platform 2 of bucket type, a column 3, a lifting boom 4, a handle 5 and a load gripping member 6.

These mechanisms have the ability to rotate with the help of drives and hydraulic cylinders in the respective planes: platform 2 is pivotally mounted with the possibility of rotation in a vertical PLANE; column 3 - in horizontal; load-lifting boom 4, handle 5 and load-gripping body 6 - in a vertical plane.

The hydraulic cylinders of the actuators 2-6 are controlled from a common hydraulic control system.

- 3 On the frame 7, the subframe 8 is rigidly fixed. The subframe 8 consists of duh spars, fastened together by cross-members, and has a cruciform amplifier in the rear part.

Brackets for attaching it to the frame 7, support plates and brackets 9 of the tilt axles of the platform 2 are welded to the side members of the subframe 8.

Column 3 is located between the rear wall of the cab of the chassis 1 and the front wall of the platform 2. Column 3 is installed behind the cab at a distance of 1 / 3-1 / 4 from the front base of the vehicle using six steps 10.

A lifting boom 4 with a handle 5 and a load gripping member 6 is pivotally fixed to the column 3.

The gripping body 6 is made clamshell. While the vehicle is moving, the load-gripping member 6 is fixed on the support 11, which is rigidly fixed in the rear part of the platform 2. The support 11 is made in the form of a trapezoid, in the upper part of which a bracket is fixed with a lock in the form of a removable finger 12, mounted on a chain.

From excessive tilting during unloading, the platform 2 is held by the safety cable 13, which is fixed at one end to the nozzle 8 and the other end to the platform 2.

A vehicle with devices for self-loading and self-unloading works as follows.

When approaching the place of cargo pick-up, the self-propelled chassis 1 is installed, if necessary, on outriggers.

When the column 3 is rotated by an angle approximately equal to 90 degrees, and by manipulating the lifting boom 4, the handle 5 and the load-gripping body b, the cargo is taken, then it is lifted above the platform 2, the column 3 is reversed to the required angular position and the cargo is unloaded to the desired site point

- 4 - 5

platforms 2. After filling the platform 2, the outriggers are removed, and the load gripping body 6 is laid on the support 11 and fixed with a removable finger 12,

Unloading the platform 2 is carried out with the load gripping body 6. In case of freezing of the cargo in the platform 2, you can use the load gripping body 6 when unloading with the corresponding manipulations with the column 3, the lifting boom 4 and the handle 5.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using modern technologies.
