Description

The claimed invention relates to devices designed for long-term storage of car tires, and to a method for using it.

In accordance with GOST 24779-81 (ST SEV 1492-79) [1], the following requirements are imposed on long-term storage of car tires:

warehouses should provide the possibility of using lifting mechanisms;

- tires, tire packs, tubeless tires and tires should be stored in a vertical position on racks, pallets or a flat floor, the load-bearing surface of the rack should be flat, without sharp edges;

- when storing tubeless tires, conditions must be provided that exclude deformation of the sides and side walls of the tires;

- every 3 months of storage, the tires and tire packs are rotated, changing the support zone.

Known warehouse for storage of tires containing racks installed in pairs with aisles between them, having support elements for tires, mounted on horizontal guides mounted in each aisle, a stacker crane with a pin gripper fixed on a movable slider perpendicular to the aisle, a reloading device for feeding tires to the rack, bundling mechanism, lifting device for tires and discharge conveyor [2].

Tire racks of this warehouse do not have a mechanism for turning tires every 3 months of storage, changing the support area, which indicates a short storage of car tires, do not meet one of the requirements of GOST 24779-81 (ST SEV 1492-79) for tire storage.

Special racks are known, equipped not with shelves, but with double horizontal beams, on which automobile tires are placed horizontally.

The distance between the beams does not exceed the diameter of the tires, so the wheels can be stored on rails in a vertical position. The tires touch the support only at two points, so they deform and wear out less if the storage period does not exceed the established norms [3].

Racks of this type have significant drawbacks, since they do not comply with the requirements of GOST 24779-81 (ST SEV 1492-79):

- the load-bearing surface of the rack has sharp ribs;

- do not allow organizing long-term storage of car tires due to the lack of a mechanism for turning tires every 3 months of storage, changing the support area.

A device for storing spare automobile wheels and tires is known, which contains a base with longitudinal and transverse vertical planes of symmetry, a metal box, a means of protection against unauthorized extraction of the first pair of spare wheels and tires from it, and a means of protection against unauthorized extraction of the second from it having the same design. pairs of spare wheels and tires [4].

The disadvantages of such a device are:

- the device is not intended for the storage of car tires on an industrial scale, the possibilities for storing car tires are limited to one set of one car;

- do not allow organizing long-term storage of car tires due to the lack of a mechanism for turning tires every 3 months of storage, changing the support area.

Thus, from the known devices and methods for storing car tires, there are no devices and methods that provide long-term storage of car tires in full compliance with GOST 24779-81 (ST SEV 1492-79).

A device for suspension of automobile wheels or tires is known, including a longitudinal tape with fasteners at both ends, a plurality of transverse tapes attached to the longitudinal tape, with loops at both ends, and adjusting cables passing through the loops of the transverse tapes [5].

The disadvantages of such a device are:

- the device is individual, which requires additional labor costs for its manufacture for each car tire;

- the device does not allow organizing long-term storage of car tires due to the lack of a mechanism for turning tires every 3 months of storage, changing the support area.

A transformable plastic container for transportation and storage of automobile tires is known, consisting of a bottom, to which, using any available method, two folding side walls are attached at the corners and in the middle of which there are quadrangular hollow elements having holes in their walls of the same diameter at the same distance located from each other. friend. Plastic retractable rods of a slightly smaller diameter are inserted into the hollow quadrangular elements, having holes that coincide with the holes on the hollow elements. The role of the remaining two walls is played by plastic rods having a reinforcing plug at their ends and coinciding in diameter with the holes in the retractable rods [6].

The disadvantages of such a container are:

- the device does not allow organizing long-term storage of car tires due to the lack of a mechanism for turning tires every 3 months of storage, changing the support area.

The technical result of the proposed device and method for long-term storage of car tires is the fulfillment of the requirements of GOST 24779-81 (ST SEV 1492-79), namely:

- warehouses where the device is installed provide the possibility of using lifting mechanisms;

- tires, tubeless tires and tires are stored in a vertical position on racks, the load-bearing surface of the rack does not have sharp edges;

when storing tires, conditions are provided that exclude the deformation of the sides and side walls of the tires;

- every 3 months of storage, the tires and tire packs are rotated, changing the support zone.

Fulfillment of all the above requirements ensures the persistence of tires during long-term storage.

The technical solution is achieved due to a fundamentally new design of the rack, placing on it horizontal beams in the form of cylindrical rollers, on which automobile tires are supported, in conjunction with a tire turning mechanism, characterized by the presence of cylindrical rollers, which are the supporting elements of automobile tires, connected by a chain transmission with a mechanism of simultaneous turning the tires around its axis on the entire rack changing the support area.

In FIG. 1 shows a schematic diagram of the proposed rack device.

The device consists of support posts 1, cross beams 2 for stiffening the structure, cross beams 3, for installation of cross support rollers 4 with technological holes 5 for different diameters of car tires, driven sprockets of support rollers 6, roller drive chain 7, cross beam 8 for installation the drive sprocket of the turning mechanism 9, the lever of the turning mechanism 10 (Fig. 1).

The method of long-term storage of tires is implemented as follows (Fig. 2).

Car tires with an outer diameter of 491 to 1260 mm are installed on a rack in a vertical position using loading equipment, supported by transverse support rollers 4. It should be noted that when installing car tires with the largest diameter, transverse support rollers 4 are installed in the extreme technological holes 5 If it is necessary to store automobile tires of a smaller diameter, the transverse support rollers 4 are installed in the technological holes 5 closer to the central axis so that the distance between the tire support points on the rollers is not less than 2/3 of the diameter and not more than 3/4. In the process of long-term storage in accordance with GOST 24779-81 (ST SEV 1492-79) every 3 months of storage, it is necessary to change the support zone of automobile tires, in this case it is necessary to turn the crank mechanism lever 10 by 3-5 turns, which in turn will entail rotation of the drive sprocket of the turning mechanism 9. Using the roller drive chain 7, the torque is transmitted from the drive sprocket to the driven sprockets 6, which in turn transmit torque to the support rollers. Rotating around its axis, the support rollers transmit torque to the car tires resting on them, as a result of which they rotate and change their support zone, which makes it possible to fulfill one of the main requirements of GOST 24779-81 (ST SEV 1492-79) during long-term storage of car tires.

The proposed device and method for long-term storage of car tires allows you to meet the requirements of GOST 24779-81 (ST SEV 1492-79) for the storage of car tires:

- the design of racks allows to place them in the closed warehouse;

- multi-tiered design of racks allows you to store a larger number of tires in a smaller area of the room;

- allows you to store car tires in a vertical position;

- the load-carrying surface of the supporting rollers has no sharp edges; Tire turning mechanism allows simultaneous turning of tires around its axis on the entire rack every 3 months of storage by changing the support area.

This device and the way it is used is new and does not explicitly follow from the prior art.

The invention relates to industrially applicable and can be used in industry.
