State of the art

Known gravitational roller rack for piece goods [1], consisting of racks interconnected by bearing shelves, which are installed at an angle to the horizon. Each shelf consists of side profiles, front and rear traverses, intermediate supports transverse to the movement of the load, as well as roller strips that are installed in grooves evenly spaced along the length of the front and rear traverses.

The disadvantage of the described design is the discrete placement of the roller strips along the length of the traverse.

The prototype for the utility model is a gravitational scaffolding roller device [7], consisting of roller slats, which, with the help of special fasteners, are installed on horizontal load-bearing elements of the scaffold frame located at different heights.

The disadvantage of the described design is the lack of fixation of the displacement of the roller strips along the horizontal load-bearing elements of the scaffold frame.

Utility Model Disclosure

The objective of the utility model is to eliminate the shortcomings of the prototype and expand the possibilities of using the rack by fixing the roller strips and dividers anywhere along the width of the carrier frame.

The technical result of the proposed utility model is to increase the reliability of the gravitational roller rack for piece goods by simplifying the design of fixing the roller bars and separators from longitudinal and transverse displacement.

The problem is solved by the fact that the gravitational roller rack for piece cargo, contains a frame, a carrier frame, roller bars and a Z-profile, while the carrier frame contains an upper and lower traverse and has a gap between the traverses and the Z-profile for fixing the roller slats and dividers , provided to prevent shifting of the load and contact between adjacent loads when rolling in the transverse direction.

Preferred shelving options:

- shims are installed between roller slats, traverses and Z-profile;

- shims are installed between the divider, traverses and Z-profile;

- traverses and Z-profile have the same thickness;

- the number of rollers on the roller bar is at least two;

- the rollers on the roller bar are arranged in a "line", in a "chessboard" or "triangle".

In addition, to improve the reliability of the rack, it is proposed to evenly distribute pressure when connecting the roller bar and separator with traverses and Z-profile, choose the same thickness of traverses and Z-profile.

It is possible to simplify the design of the rack by using two or more rollers on the same axis, which reduces the number of roller bars and increases the stability of the load when rolling.

In addition, to expand the possibilities of using the rack, you can adjust the angle of inclination of the roller bar by installing adjusting shims between the bar, the lower traverse and the Z-profile, the number and thickness of which allows you to select the desired angle of inclination of the roller bar; adjust the height of the divider in relation to the roller bar by installing between the divider, the lower traverse and the Z-profile of adjusting shims, the number and thickness of which allows you to select the required height of the divider; and you can also choose the number of rollers on the axle and their location on the roller bars, taking into account the weight of the cargo and the material of the container.

Implementation of the utility model

Gravity roller rack for piece goods consists of three main elements (Fig. 1): frame 1, carrier frame 2 and roller slats 3.

The frame 1 is assembled from racks 4, beams 7, braces 5 and supports 6. The supporting frame 2, consisting of side profiles 8, upper and lower traverses 9, intermediate supports 10 is fixed on the frame 1.

A design feature of gravity roller racks for piece goods is the inclination of the roller slats 3 between the upper and lower traverses 9 of the carrier frame 2, due to which the load under the action of gravity rolls along the rollers 18 located in the roller slats 3.

The load rolls on roller bars 3, the number of which, for example, one, two or more, is selected taking into account the mass and dimensions of the load, the container material, and which are located symmetrically about its center of gravity. To prevent displacement of the load and contact between adjacent loads when rolling in the transverse direction, dividers 11 are provided, made, for example, in the form of a profile pipe.

Roller strips 3 and dividers 11 are installed on the upper and lower cross-beams 9 of the carrier frame 2 and are fixed to them, for example, using threaded rivets 13 (Fig. 2a and 3a), which are placed in the horizontal gap δ between the cross-beams 9 and the upper shelf Z- profile 12 and, for example, bolts 14, spring washers 15 and washers 16. The gap δ is designed to accommodate the fastener of the roller strip 3 and separator 11. The lower shelf of the Z-profile 12 is installed on the side profiles 8 and fixed to them, for example, using threaded rivets 13 (Fig. 4).

The fastening of the roller slats 3 and spacers 11 in the gap δ allows you to fix the roller slats 3 and spacers 11 from longitudinal and transverse displacement anywhere along the width of the carrier frame, and the gap δ between the traverses 9 and the Z-profile 12 allows you to move the roller slats 3 and spacers 11 on the width of the supporting frame 2 without restrictions.

To adjust the angle of inclination of the roller bar between the traverses 9, the Z-profile and the roller bar 3, shims 17 are installed (Fig. 2b), for example, washers or plates, the number and thickness of which allows you to select the desired angle of inclination of the roller bar for rolling piece cargo.

To adjust the height of the divider 11 in relation to the roller bar 3 between the divider 11, the traverses 9 and the Z-profile, adjusting shims 17 (Fig. 3b) are installed, for example, washers or plates, the number and thickness of which allows you to select the required height of the divider.

For uniform distribution of pressure in the connection of the roller strip 3 and separator 11 with traverses 9 and Z-profile 12, the thicknesses of traverses 9 and Z-profile must be the same.

To reduce the number of roller slats 3 and increase the stability of the load during rolling, it is possible to install, for example, two or more rollers 18 on one axis 19 (Fig. 5).

The design of the rack allows the number of rollers 18 on the axis 19 and their placement on the roller slats 3 to choose based on the weight of the cargo and the material of the container, for example, corrugated cardboard, plastic, wood, metal. Examples of options for the number of rollers 18 on the axis 19 and the location of the rollers 18 on the slats 3 are shown in Fig. 6.

The proposed gravitational roller rack for piece cargo allows you to obtain the claimed technical result, namely, to increase the reliability of the rack by simplifying the design of fixing the roller bars and dividers from longitudinal and transverse displacement, as well as expand the possibilities of its application by fixing the roller bars and dividers anywhere in the carrier frame .
