SU1238991A1 - Container semitrailer with loading and unloading devices - Google Patents

Description

The invention relates to automobile vehicles, and more specifically to container semi-trailers with devices for self-loading and self-unloading.

Closest to the invention is a container semi-trailer with devices for loading and unloading, each of which includes a boom with a telescopic telescopic part and a container gripping device hinged on a loading platform with swinging capability in a transverse vertical plane connected by means of a hydraulic cylinder on the unloading side, with the outboard support pivoting in the same vertical plane, one end of which is hinged on the load platform, and stroystvo for locking the boom 1.

However, the known device is unreliable in operation due to the large number of hydraulic cylinders and locking devices.

The aim of the invention is to improve the reliability of the semi-container carrier in operation.

This goal is achieved by the fact that in a container semi-trailer with devices for loading and unloading, each of which includes a boom with a telescopic sliding part and a container gripping device, hinged on a cargo platform with the possibility of swinging in a transverse vertical plane and pivotally connected by means of a hydraulic cylinder mounted on the unloading side, with an outboard support rotating in the same vertical plane, one end of which is hinged on the load platform, and the device for fixing the boom, the boom is curved so that its telescopic part in the lowering position of the container on the platform is perpendicular to the latter, and the hinge point of the boom to the loading platform is mixed relative to the longitudinal axis of symmetry in the direction opposite to the unloading side, while the gripping device is fixed directly at the end of the retractable telescopic part.

FIG. 1 schematically shows a container semi-trailer, rear view (at the time of unloading); in fig. 2 - the same at the time of installation of the outrigger; in fig. 3 - the same, at the moment of lifting the container over the platform; in fig. 4 - the same.

at the time of installation of the container on the earth; in fig. 5 - lower part of the boom with retainer.

The container semi-trailer contains a cargo platform 1 with two devices for loading and unloading, consisting of a curved boom 2 hinged on the platform with a telescopic sliding part 3, at its free end a lifting device 4

0 (for example, slings or chains) for the container 5, the outrigger support 6, the hydraulic cylinder 7 pivotally connected to the boom, and the device for fixing the boom in the form of the stop 8 mounted on the platform from the side opposite to the unloading side, the latch 9 fixed inside the boom and springs 10.

A hydraulic cylinder 11 is mounted inside the boom 2 to move the telescopic portion.

0 The work on unloading a semi-trailer container carrier is carried out as follows.

The outriggers 6 are installed on the ground by means of a hydraulic cylinder 7, then the container 5 is lifted above the cargo platform 1 by extending the telescopic part 3 by a hydraulic cylinder 11. In this case, the latch 9 is removed from the stop 8 by the action of the spring 10. After the working fluid is discharged from the piston cavities

0 of the hydraulic cylinder 7, while the boom 2, due to the fact that its pivot point is shifted relative to the longitudinal axis of symmetry, will begin to tilt under the action of the weight of the container 5 and transfer it to the place of unloading. After the container 5 is placed on the ground and released from the gripping device 4, the working fluid is supplied to the piston cavity of the hydraulic cylinder 7 and the boom 2 returns to the transport position. When lowering the telescopic part 3, the latch 9 is fixed on the support 8. Then the working fluid is fed into the rod cavity of the hydraulic cylinder 7 and the outrigger support also comes into the transport. position.

The container is loaded onto the semi-trailer in reverse order, with the container 5 being lowered onto the loading platform 1 at the moment when the telescopic part 3 of the curved boom is perpendicular to the loading platform 1.

The use of the invention allows

 to increase the reliability of work when loading and unloading a semi-container carrier.
