Abstract

The technical objective of the utility model is the introduction and use of a device of variable length for loading and unloading operations in road transport when carrying out loading and unloading operations with portable weapons and military equipment (mortars, anti-aircraft guns), missiles, ammunition, military equipment and other materiel . The technical problem is solved due to the fact that it is used: a device of variable length for loading and unloading operations in road transport, consisting of several elements of the first, second, third sections, interconnected by connecting loops and with the loading platform of the car in place of the tailgate using fasteners articulated type with roller bearings. A device of variable length for loading and unloading operations in road transport consists of several elements: sections, first, second, third 1, hinges 2, connecting loops 3, roller bearings 4. The operation of the device is ensured by its attachment to the cargo platform of the car in place of the rear sides, which, depending on the conditions of loading and unloading operations, makes it possible to change the length of the device of variable length for loading and unloading operations in road transport, the required position of the sections is fixed using connecting loops, the sections have the ability to change the angle of inclination and transfer to the working position by tilting sections that are made of different lengths.

Description

A device of variable length for loading and unloading operations in road transport belongs to the field of loading and unloading devices, in particular to auxiliary equipment, and is intended for loading (unloading) transportable weapons and military equipment (mortars, anti-aircraft guns, small arms, military equipment ), rockets, ammunition and other materiel both in stationary warehouses and on non-equipped sites, railway platforms, railway tracks, both public and non-public.

A device for loading (unloading) military equipment and containers with potentially hazardous products in road transport is known. (Patent of the Russian Federation No. 2677431 for 2019 [1]).

Known overpass for loading and unloading monocargoes and wheeled vehicles during transportation in aircraft such as heavy transport aircraft AN-124-100. (Patent of the Russian Federation No. 2172708 for 2001 [2]).

Known mobile overpass for unloading vehicles. (USSR author's certificate No. 1659333 for 1991 [3]).

Known airfield cargo ladder. (USSR author's certificate No. 247800 for 1969 [4]).

The disadvantages of known inventions are:

lack of mobility;

constructive and technological complexity of manufacturing;

cumbersome structures;

for installation and start of work, it is required to attract additional vehicles both for transporting elements of products and for delivering a rigging team to the installation site of the structure;

in a real combat situation, it is difficult to move product elements to places of loading (unloading);

a time period is required before starting work for the installation and adjustment of structural elements.

The purpose of the utility model is to create a device of variable length for loading and unloading operations in road transport, containing in its composition a loading and unloading three-section ladder of variable length, consisting of several elements of the first, second, third sections, interconnected by connecting loops and with the cargo platform of the car in place of the tailgate using hinge-type fasteners with roller bearings, characterized in that the required position of the sections is fixed with the help of connecting loops, the sections have the ability to change the angle of inclination and transfer to the working position by tilting the sections, which are made of different lengths.

The technical task of the utility model is the introduction and use of a device of variable length for loading and unloading operations in road transport when carrying out loading and unloading operations with portable weapons and military equipment (mortars, anti-aircraft guns), missiles, ammunition, military equipment and other materiel .

The technical problem is solved due to the fact that it is used: a device of variable length for loading and unloading operations in road transport, consisting of several elements of the first, second, third sections, interconnected by connecting loops and with the loading platform of the car in place of the tailgate using fasteners articulated type with roller bearings.

A variable length device for loading and unloading operations in road transport consists of several elements: sections, first, second, third 1, hinges 2, connecting loops 3, roller bearings 4.

The operation of the device is ensured by its attachment to the cargo platform of the car at the place of the tailgate, which, depending on the conditions of loading and unloading operations, makes it possible to change the length of the device of variable length for loading and unloading operations in road transport, the required position of the sections is fixed with the help of connecting hinges, sections have the ability to change the angle of inclination and transfer to the working position by tilting the sections, which are made of different lengths.

In FIG. 1 shows a variable length device for loading and unloading operations in road transport during loading and unloading operations with portable weapons and military equipment (mortars, anti-aircraft guns), missiles, ammunition, military equipment and other materiel, consisting of several elements: sections, first, second, third 1, hinges 2, connecting loops 3, roller bearings 4.

In FIG. 2 shows a device of variable length for loading and unloading operations in road transport, in the stowed position, ready for the car to march, consisting of several elements: sections, first, second, third 1, hinges 2, connecting loops 3, roller bearings 4, cargo car platform 5.

In FIG. 3 shows a device of variable length for loading and unloading operations in road transport, in working condition for carrying out work as intended, consisting of several elements: sections, first, second, third 1, hinges 2, connecting loops 3, roller bearings 4, cargo platform car 5.

The principle of operation of the variable length device for loading and unloading operations in road transport is as follows: a three-section ladder of variable length, consisting of several elements of the first, second, third sections 1, interconnected by connecting loops 3 and with the cargo platform of the car in place of the tailgate with with the help of hinged type mounts 2, having roller bearings 4, depending on the particular conditions of carrying out loading and unloading operations, with the help of sections that can change the angle of inclination and transfer to the working position by tilting the sections, which are made of different lengths, allows through little physical effort move reloaded material in accordance with the required task. In private conditions, it is possible to use only the first section 1 of the device of variable length for loading and unloading operations in road transport, if necessary, use two or three sections 1 of the device of variable length for loading and unloading operations in road transport, the required position of the sections is fixed using connecting loops (Fig. 1, p. 3).

Thus, the use of a device of variable length for loading and unloading operations in road transport can significantly reduce the time of loading and unloading operations, reduce the number of personnel involved in these works. Due to the specifics of the design, a variable length device for loading and unloading operations in road transport is convenient to use in various ways of loading (loading) a car, reloading cargo and other material means into various types of transport, including using rigging equipment and other improvised means.
