Abstract

FIELD: transport.

SUBSTANCE: invention relates to vehicles cargo handling mechanisms. Design of self-unloading body comprises mounted on wheels chassis, on which body and tipping mechanisms are installed. Body frame is made so, that in unloaded state it is raised and connected with energy accumulation mechanism in form of pneumatic cylinders and receiver. Receiver is actuated at moment of loading, and at moment of unloading body is capable to shift aside along guide beams by gravity. Guide beams are installed inclined, and body is tipping due to accumulated energy, and using pneumatic cylinders it is returned into initial position.

EFFECT: enabling unloading mechanism operation increasing.

Description

The invention relates to mechanisms for moving goods of vehicles. It can be used for any vehicle moving bulk and bulk materials. Known mechanisms and body structures for unloading and tipping. The copyright certificate RU 2106985 describes a body structure with a sheet of flexible material. This design is inconvenient for transportation and unloading of large stone blocks. There are designs of self-unloading cars like Dumkar. For example, the design is described in patent RU 2461479. In all structures, an external energy source is mainly required for unloading.

A self-unloading body design using the potential energy of the transported cargo is proposed. The structure consists of a frame (2) of FIG. 1, 3, 4, which is mounted on the chassis (1) of FIG. 1, 4. The frame includes guide beams (14) of FIG. 2, 3 in which the rollers (3) of FIG. 3 and the rollers (3.1, 3.2, 3.3) of FIG. 1, 4. The beams at the ends have a locking mechanism (9) of FIG. 1, 2. Along the beam from above there is a slot (11) of FIG. 2 for the free movement of the body frame supports mounted on rollers. In the center of the beams is a window (10) of FIG. 3, 4 exceeding the size of the roller. On the rollers (3) of FIG. 3, the body frame (5) of FIG. 1, 3 and the body itself (4) of FIG. 1. On the body frame (5) of FIG. 1, a movable counterweight (12) of FIG. 1, 4. In addition, there are several extendable supports (7) of FIG. 1, 4 to prevent tipping of the chassis and the tipping limiter of the body (6) of FIG. 4. Between the frame (2) of FIG. 1, 4 and the chassis (1) of FIG. 1, 4, the pneumatic cylinders (8) of FIG. 1, 4 and the receiver (13) of FIG. fourteen.

The principle of construction

When unloaded, the frame with the body is in a raised position. After loading by gravity, the body (4) of FIG. 1, 4 with the frame (2) of FIG. 1, 4 are lowered to the stops (15) of FIG. 1 and air from the pneumatic cylinders (8) of FIG. 1, 4 enters the receiver (13) of FIG. 1, 4. At the time of unloading, the supports (7) of the FIG. 1, 4 towards unloading; the locking mechanism (9) of FIG. 1, 2, freeing the roller (3.3) of FIG. 1, 4 for free movement; limiter (15) of FIG. 1 from the unloading side goes down and the frame (2) of FIG. 1, 4 takes an inclined position, as a result of which under the influence of gravity the body frame (5) of FIG. 1, 4 on the rollers (3.1, 3.2) of FIG. 1, 4 rolls down towards unloading; after the roller (3.3) of FIG. 1, 4 went beyond the beam (14) of FIG. 2, 3, the locking mechanism (9) of FIG. 1, 2 is initialized, obstructing the roller (3.2) of FIG. 1, 4 go beyond the beam (14) of FIG. 2, 3; the roller (3.2) of FIG. 1, 4 comes to the stop and the roller (3.1) of FIG. 1, 4 is opposite the window (10) of FIG. 2, 4, and the counterweight (12) of FIG. 1, 4 is shifted towards unloading, changing the center of gravity of the body, as a result of which the body capsizes under the action of gravity, and the limiter (6) of FIG. 4 prevents its full overturn; after the discharge is completed, air from the receiver (13) of FIG. 1, 4 is fed into the pneumatic cylinders (8) of FIG. 1, 4 from the discharge side, which raise the frame (2) of FIG. 1, 4, bringing it into a horizontal position and thereby freeing the body (4) of FIG. 1 from the blockage of bulk cargo; counterweight (12) of FIG. 1, 4 by means of a pneumatic system moves to the opposite position, the center of gravity changes, as a result of which the body (4) of FIG. 1 comes into a horizontal position, and the roller (3.1) of FIG. 1, 4 enters the window (10) of FIG. 2, 4; limiter (15) of FIG. 1 on the opposite side of the discharge drops down, the frame (2) of FIG. 1, 4 takes an inclined position and under the influence of gravity the body (4) of FIG. 1 takes a starting position; the retainer (9) of FIG. 1, 2 from the unloading side is removed from the locking position, freeing up access to the roller (3.3) of FIG. 1, 4 into the beam (14) of FIG. 2, 3; the roller (3.1) of FIG. 1, 4 comes to a stop, and the roller (3.3) of FIG. 1, 4 is fixed; supports (7) of FIG. 1, 4 are reset; compressed air from the receiver (13) of FIG. 1, 4 enters the pneumatic cylinders (8) of FIG. 1, 4, which raise the frame, bringing it to its original position. To actuate all the mechanisms, the energy of compressed air is used to the maximum.

This invention can be used in vehicles for the transport of bulk and bulk cargo in the agricultural industry, for work in quarries, in road construction. The invention allows maximum use of the potential energy of the transported cargo to ensure the operation of the unloading mechanism.

Claims (1)

A self-unloading body structure comprising a chassis mounted on wheels, a body mounted on the latter and tipping mechanisms, characterized in that the body frame is raised and connected to the energy storage mechanism in the form of pneumatic cylinders and a receiver, which is actuated at the moment loading, and at the time of unloading, the body is able to shift to the side under the influence of gravity along the guide beams, which are placed at an angle, and capsize, after which due to lennoy energy by means of pneumatic cylinders is returned to the original position.
