Description

The utility model relates to the bodies of tipper vehicles - trailers and semi-trailers of tractor transport and can be used for transporting various types of wet sticky goods. Usage: for tractor transport of wet rock, which is loaded directly into the body, and unloaded by tipping the body.

A dump truck is known (patent RU No. 86534, publ. 10.09.2009), containing a chassis, a tilting body mounted on the chassis with hinged sides, hinged on the lower hinges. Folding side boards are made folding in the plane of the board.

The disadvantage is the presence of detachable connections around the perimeter of the rectangular body, which leads to insufficient reliability of the body during the transportation and unloading of wet rock and its sticking of wet cargo to the bottom of the body, especially at the joints between the side walls and the bottom of the body.

A dump trailer is known (patent RU No. 2703698, publ. 10/21/2019), containing a chassis, a body with basic rectangular body contours, the outer surface of the side walls of the body is equipped with structural reinforcement jumpers, and the edges of the tailgate are supplemented with side restraints to prevent spillage of cargo to the sides , hydraulic cylinders for lifting the body are located on the outriggers. The advantage of this invention is the high reliability in the transportation of long and heavy loads.

The disadvantage is the large weight of the trailer body due to the strengthening of the structure with stiffeners along the perimeter of the body.

Known dump truck with a rotary design of the lifting mechanism for tipping the body on the left, right and rear sides (patent RU No. 2710960, publ. The advantage of this utility model is three-sided unloading by the body.

The disadvantages include the rectangular shape of the body, which is prone to sticking of wet cargo to the bottom of the body, especially at the joints between the side walls and the bottom of the body.

A semitrailer dump truck is known (patent BR 202014003358, publ. 10/20/2015), containing a body with folding sides, detachably connected around the perimeter of the flaps and allowing unloading when tipping the body sideways using the flaps with the lower and upper hinges. The side wall of the body can be opened in a hinged way on the upper and lower hinges and according to the principle of hinged doors.

The disadvantage is the presence of detachable connections around the perimeter of the rectangular body for folding and folding openings of the side walls of the body, which leads to insufficient reliability of the body during the transportation and unloading of wet rock and its sticking of wet cargo to the bottom of the body in the joints between the side boards and the bottom of the body. Also, the disadvantage is the opening of the body during lateral unloading on the upper hinges, located significantly below the edge of the body, which limits the opening for the passage of cargo, which can cause an increased load on the edge of the body.

Known tipper body as part of a dump truck, containing the front and side walls, the bottom of a semi-elliptical shape in cross section and fixed on the axis of the rotary mechanism for tipping the body on its side (Shiryaev S.A., Gudkov V.A., Mirotin L.B. Transport and loading and unloading means: textbook for universities, edited by Shiryaev SA - M.: Hotline-Telecom, 2007. - 847 p.), adopted as a prototype. The semi-elliptical steel bottom is rigidly connected at the ends with the front and rear steel walls, forming a rigid spatial structure in the form of a box with a semi-elliptical bottom.

The disadvantage of the known tipper body is a small usable volume of the body. Due to the semi-elliptical shape of the bottom, a high center of gravity is provided, which violates the stability of the dump truck when unloading on its side.

EFFECT: increased efficiency of loading, unloading and transportation of wet rock.

The technical result is achieved by the fact that the front and side boards are rigidly connected to each other and to the bottom, which is made in the form of two half-cylinders of constant cross section, from bent solid sheets, along the profile of the steepest descent curve - brachistochrones, and are rigidly connected to each other and in front with the front board , which is installed at an inclination to the axis of the body, and is rigidly connected to the connecting plate, and on the other hand to the side boards, while forming a stiffening rib in the form of a hollow triangular section between the bottom and the connecting plate, in the lower part of the front board and along the axes of the bottom half-cylinders holes are made.

The body of a dump vehicle is illustrated by the following figures:

fig. 1 - general view of the device;

fig. 2 - front wall of the body;

fig. 3 is a side view of the device, where:

1 - front side;

2 - bottom;

3 - side boards;

4 - stiffener;

5 - hole;

6 - connecting plate.

Body tipper vehicle consists of rigidly interconnected front board 1 (Fig. 1-3), side boards 3 bottom 2, which are made of sheets, such as steel. The bottom 3 is made in the form of two semi-cylinders of constant cross section, bent from solid sheets, for example, from steel along the profile of the steepest descent curve - a brachistochrone, and rigidly connected to each other and in front with the front side 1. The front side 1 is installed at an angle to the axis of the body and is rigidly connected to connecting plate 6, and on the other side with side boards 3, forming a stiffener 4 of a hollow triangular section between the bottom 2 and the connecting plate 6. Holes 5 are made in the lower part of the front board 1. Holes 5 are made along the axes of the half-cylinders of the bottom 2.

The body of the tipper vehicle works as follows. The body is mounted on the chassis of a vehicle equipped with a lifting mechanism, for example in the form of a hydraulic cylinder with a retractable rod. The body can be loaded with various types of cargo, including heavy and wet bulk cargo. When loading the body, for example, with a single-bucket excavator, the first buckets with wet rock are unloaded into the front of the body on the stiffener 4. The water that got into the excavator bucket when excavating the rock enters the body and drains through holes 5 in the front side 1 and the bottom 2. The rock material is distributed in the body evenly into two parts between the semi-cylinders of the bottom of the body. When lifting the body for unloading, the rock, divided by the stiffener 4 into two parts, slides more easily along the bottom of the body, formed from two half-cylinders.

When using a body with a bottom formed from two rigidly connected semi-cylinders of constant cross section, the efficiency of loading and unloading bodies of dump trailers increases when transporting wet rock and, as a result, the productivity of rock removal on soft soils increases.
