Description

The invention relates to mechanisms for transferring a packaged load from the top to the bottom of a van of a van with a ring loading-unloading scheme.

A van is known with a ring-loading-unloading scheme, the body of which is equipped with guides parallel arranged in vertical planes and made in the form of rectangular frames. These guides accommodate crossbeams rolling in them, to which load 1 is placed.

The disadvantage of this design is the low loading density.

A van box for transporting packaged cargoes is also known, comprising guides arranged in two tiers, a device for transferring loads from guides of the upper tusk to guides of the lower tusk, fitted with vertical guides fixed in the front part of the wagon body moving along them frame carriage, on the sides of which the rollers and load-carrying elements are mounted with the possibility of rotation around its axis, and the stops fixed on the vertical rails at the level of the upper and lower 2. Body its tiers different constructive complexity and lack of reliability in operation. This is explained by the fact that the load (container) mounted on the load-carrying elements, creates significant friction when moving the latter in the shaped grooves, which is also enhanced by the impact of the stop of the lower tier. Friction in the elements makes axial movement and rotation of the rollers difficult, which

leads to increased wear of the fingers and shaped grooves and the hang of the carriage in the guides.

The aim of the invention is to increase reliability in operation.

This goal is achieved by the fact that cams are rigidly attached to the rollers, connected by a spring to the carriage and interacting with the stops, and grooves for the load-carrying elements are made on the lower rush guides.

FIG. 1 shows a box body, general view; in fig. 2 - the mechanism for moving the load from the upper to the lower rus, the upper position; in fig. 3 - the same, the lower position; in fig. 4 is a view A of FIG. 2;

in fig. 5 - swivel roller; in fig. 6,

7- phase rotation of the rotary roller when moving the carriage down; in fig. 8, 9 - the same, when moving the carriage up.

In the body of the van, horizontal guides 1 and 2 are placed in two wheels to install and move containers 3.

8 the rear part of the body is a lifting mechanism 4, designed to load containers in the upper rus and unload them from the lower rus.

In the front part of the body, the upper and the lower rus are connected by a device for reloading goods, intended for the piecewise movement of containers from the upper rusa to the lower one.

The overloading device (Figs. 2, 3, 4) consists of two channel-like vertical guides 5 in which the carriage 6 of the frame structure moves on the rollers and is connected to the lifting mechanism 7, which is any reciprocating mechanism, for example hydraulic cylinder. In the crossbars 8 of the carriage 6, pivotal pivots 9 are installed with load-carrying elements 10 with stops P. fixed on them. Each roller is provided with a cam 12 fixed on it, to which a spring 13 eccentrically attached, attached to the carriage 6.

In the upper position of the carriage 6, the load-carrying elements 10 are held in a horizontal position by springs 13 and stops 11, which cooperate with the crossbar 8. At the level of the upper arm there is a stop 14, designed to return the load-carrying elements 10 to a horizontal position.

In the guides 2 of the lower russ there are recesses 15 for the load-carrying elements 10, and stops 16 are installed to turn them. The movement of cargo from the upper tier to the lower is carried out as follows.

Under the action of the mechanism 7, the carriage 6, with the load sitting on the load-carrying elements 10, begins to fall down. When the latter reaches the lower rush level, the load remains on the guides 2, the carriage 6

moves further down, the load-carrying elements 10 and the stops 16 (Fig. 6) enter into interaction, as a result, as well as under the action of the springs 13 that have passed the dead point, the rollers 9 turn to the stop of the load-carrying elements 10 into the cross member 8 (Fig. 7) .

When lifting, the load-carrying elements 10 freely pass by the load standing on the guides 2. When the level of the upper tier (Fig. 8) is reached, the cams 12 interact with the stops 14 and, under the action of the springs 13 that have passed the dead point, begin to turn the rollers 9 with the load-carrying elements 10 before the contact of the stops 11 with the cross-pieces 8 (Fig. 9), which corresponds to the horizontal position of the load-carrying elements 10. The overload mechanism is ready for the next cycle.
