SUBSTANCE: invention relates to the field of mechanical engineering, and more specifically, to containers. The universal shipping container consists of a main body and roll-out racks. At least one of the sides of the container is easily collapsible, representing protective shutters. Racks are divided by walls into cells. Non-adjacent side walls of the cells are made folding. The racks are installed in at least four retractable telescopic rails spaced in pairs along the height of the container. The racks are equipped with limiters for forward and reverse movement, made in the form of pawls of a bidirectional linear ratchet mechanism.

Description

The invention relates to devices representing an enlarged cargo unit, designed for storing material assets, such as military equipment, as well as for transportation by various modes of transport.

A mobile multifunctional module is known (RF patent No. 198716), including a main body containing a frame, characterized in that the module is made with the possibility of placing the bottom on the ground, the frame has a lattice structure, openings are made in the sides of the frame, and holes are made in its ceiling part . The mobile multifunctional module is equipped with a lifting mechanism from the ground, made in the form of cylindrical rods, placed in the inner space of the side walls of the frame. The mobile multifunctional module is equipped with a telescopic section installed with the possibility of extension away from the main body, while the width of the mobile multifunctional module in the folded state does not exceed 2.5 m, length - 7 m, height - 2.5 m [1].

The disadvantages of such a device are:

- the impossibility of a quick search for the necessary property, with a maximum load of the internal space, as well as prompt issuance, unloading of the necessary property;

- the impossibility of organizing an orderly placement of property, as well as its accounting with reference to any groups, for example, by car brands.

Known universal unified containers designed for the carriage of goods mainly without shipping containers by rail, water and road transport, including large-capacity containers, as well as universal low-capacity containers, automobile containers for direct transportation of these goods by road [2], of which are closer to the declared the technical solution is a metal large-capacity container 1CX. The container includes two longitudinal lower beams with forklift pockets, two longitudinal roof beams, two lower and two upper cross beams, two side and one end walls, a roof and two end doors with a locking mechanism.

The disadvantage of such a container is:

- the impossibility of organizing the orderly placement and storage of property;

- the impossibility of searching, promptly issuing, unloading the necessary property, with the maximum load on the internal space of the container.

It is also known a device for storing and transporting automotive property (RF patent No. 208609) [3], which has roll-out racks that can be pulled out when the doors are open, located on one of the sides of the main body, along guide rails installed on the floor, ceiling of the main body and on folding doors. This device has the following disadvantages:

- the need to tilt the door, which adds to the overall size of the device the maximum length of the roll-out of the rack, even if it is required to provide access to the rack cell closest to the hinged door;

- the vertical stability of the rack decreases when it is rolled out, because it is provided (on folding doors) that only the rail guides located on the floor of the housing are continued - the upper guides do not have a continuation.

The purpose of the invention is the creation of a universal transport container for transportation, temporary storage and issuance of a sorted range of material assets with the possibility of its prompt partial issuance, regardless of location and distance from the housing wall.

This is achieved by the fact that the container consists of a main body and roll-out racks, while at least one of the sides of the container is easily collapsible, representing protective shutters, the racks are divided by walls into cells, non-adjacent side walls of which are made folding, the racks are installed at least in four retractable telescopic guides spaced in pairs along the height of the container, and the racks are equipped with forward and reverse motion limiters made in the form of pawls of a bidirectional linear ratchet mechanism. The length of any cell is a multiple of the pitch of the gear rack of the linear ratchet mechanism, and the pitch of the gear rack teeth is no more than the length of the smallest cell.

The declared features are essential:

Separation of the cells of the racks by the walls contributes to the safety of material assets during the longitudinal and transverse accelerations of the container, the occurrence of heels during its transportation or reloading, the extension of the racks during unloading.

Installing the rack in retractable telescopic guides, spaced in pairs along the height of the container, ensures vertical stability of the rack when it is rolled out.

The implementation of telescopic sliding guides allows you to roll out the rack to its full length, providing access to the most distant cells.

The execution of the container wall is easily collapsible and the use of retractable telescopic guides of high load capacity allows to reduce the additional overall size of the container caused by the roll-out of the rack to the limit necessary for access to the required cell with material assets. Thus, an increase in the speed of bypassing the container by the loading and unloading operator (PRR) or bypassing by automated means of the LRR, including robotic means for ensuring the LRR process, is achieved. The introduction of forward and reverse motion limiters into the design and their implementation as part of a bidirectional linear ratchet mechanism in the form of pawls allows not only limiting the rack rollout to the limit necessary to access the required cell with material assets, but also fixing the installed rollout with a backstop. Rolling up the rack is accompanied by the reverse process. The degree of discreteness of fixing the roll-out of the rack can be increased by reducing the distance between the teeth of the rack.

The use of a bi-directional linear ratchet mechanism provides for facilitating the process of pulling out racks in case of transverse distortions of the container, when the forward and reverse stroke limiters will be anti-recoil devices.

The multiplicity of the length of any cell to the pitch of the gear rack teeth of the linear ratchet mechanism, limiting the maximum pitch of the gear rack teeth to the length of the smallest cell ensures the accuracy of rolling out the rack cells.

At the same time, the introduction of forward and reverse motion limiters to perform the above functions has an additional effect: preventing rack vibrations during container transportation, which can cause damage to the walls and locking devices (locks, shutter drives) of the container, leading not only to a violation of the integrity of the container and a threat to the safety of the cargo, but also to the fundamental impossibility of unloading due to a malfunction of the locking devices.

On FIG. 1 shows a diagram of one of the design options for a universal shipping container.

The container consists of a body 1 with protective shutters 2, has roll-out racks 3, consisting of cells with dividing walls 4 and folding side walls 5; the racks are installed in retractable telescopic guides 6. The bidirectional linear ratchet mechanism includes two gear racks 7 with opposite directions of oblique teeth (for forward and reverse rack movement), spring-loaded pawl limiters are controlled by rods 8 driven by shafts 9, the rotation of which is carried out with the help of handles 10. On each shaft, there are only one type of limiter rods at the same time - forward or reverse motion, while on a pair of shafts there are limiters of both types. Pawls are located under the opposite ends of the length of the racks to ensure the restriction of movement in the entire range of extension lengths to both sides of the container.

On FIG. 2 shows the layout of the pawl limiter in one of the design options for a bidirectional linear ratchet mechanism. The pawl 11 is spring-loaded by the spring 12 for transferring the pawl to the next tooth of the gear rack 7 and the spring 13 for retracting the pawl to remove the stroke limiter by means of a rod 8.
