Description

The claimed technical solution relates to devices for transporting packages with UF ₆ (hereinafter - packaging), made in accordance with the requirements of a single container transport system.

 A single container transport system provides for the transportation of goods in universal unified containers using unified methods of securing in rail, water or road transport.

A device for transporting packages is known (Collection of reports of the seminar "Uranium Transport: How it is done" March 10-14, 1994, Voronovo, annex to the report - drawing 3-470-027-00-00 of the German concern "Nuclear Cargo Service", FIG. .1), allowing the transport of one type 48 package (“package 48” - transport container with UF ₆ no ISO 7195 “Packaging of uranium hexafluoride for transportation”; payload -12.5 tons, total package weight up to 14.8 tons; hereinafter - "48 pack") or not more than four packages of 30 ( "30 pack" - the transport container of UF ₆ to ISO 7195 "packaging hexafluoro and uranium for transportation "and a protective cover, useful weight - 2.2 tons, the total mass of the package up to 4 tons; hereinafter - the" package 30 "). The device consists of a container platform with an incomplete superstructure (codes 61 and 62 according to ST SEV 3550-82), interchangeable support pads for packages, one-time stretch marks. As one-time stretch marks, both wire stretch marks and special ones - belts or tapes with locks are used.

 The transportation device is mounted on a railway platform and secured with fittings in accordance with the requirements of a single container transport system. Packages are installed on supporting linings (mainly wooden) and are fastened with one-time stretch marks.

The disadvantages of this device are:
1. Insufficiently efficient use of the loading area of vehicles (for example, when transporting “packages 48” on a container train platform for large containers, no more than three “packages 48” can be transported);
2. The need to use an individual set of fasteners and interchangeable support pads during transportation of various types of packages;
3. The need to replace stretch marks after one-time transportation of the package.

 The closest in technical essence to the claimed solution is a device for transporting packages of the German concern "Nuclear Cargo Service" (Collection of reports of the seminar "Uranium Transport: How it is done" March 10-14, 1994, Voronovo, annex to the report - drawing 3-470 -045-00-00, figure 2), selected as a prototype.

 The device consists of a platform container with an incomplete superstructure (codes 61 and 62 according to ST SEV 3550-82), a removable support device for one (for transportation of “packages 48”) or four (for transportation of “packages 30”) packages, bolted connections ( when transporting "packages 30") or multi-turn extensions, including chains, staples, turnbuckles (for transporting "package 48"). The interchangeable support device is a frame structure having seating surfaces for one “package 48” or for four “packages 30”.

 On a container platform with an incomplete superstructure, a removable support device is installed and fixed. Then this transportation device is mounted on a vehicle (for example, a container container train platform or a container container semitrailer) and secured with fittings in accordance with the requirements of a single container transport system. The packaging is mounted on the support fixture. The “packages 48” are attached to the removable support device by multi-turn extensions (the brackets go into the eyes of the “package 48”, the chain is pulled with a lanyard perpendicular to the longitudinal axis of the package) and the stops made in the removable support device (the edges of the “package 48” go between the stops support device). The fastening of the “packages 30” to the interchangeable support device is carried out by bolted connections.

The disadvantages of this device are:
1. Insufficiently efficient use of the loading area of vehicles (for example, when transporting packages 48 on a container carrier platform for large containers, no more than three “packages 48” can be transported).

2. When transporting various types of packages for each type, it is necessary to have an individual set of fastening means and a removable supporting device;
3. The high complexity of the process of fixing-removing the "packaging 30";
4. The lack of strict fixation of the "packages 48" in the axial direction by stops made in a removable support device. As the practice of operating such a method of fastening packages has shown, during transportation they periodically move along the longitudinal axis (within the guaranteed gap between the support rib and the stop groove). This leads to dynamic impacts of the supporting ribs of the package on the walls of the grooves of the stops and an increase in the axial load in one pair of stretch marks (fixed perpendicular to the longitudinal axis of the package) and weakening in the other.

The objective of the invention is:
- increasing the efficiency of using vehicles;
- increase the safety of transportation.

When implementing the invention, the following technical results are achieved:
- the ability to refuse to use a container platform with an incomplete superstructure and install on the vehicle a larger (compared to the prototype) number of packages, or use a smaller vehicle, thereby increasing the efficiency of use of vehicles;
- refuse to use interchangeable support devices, reduce the complexity of mounting packages;
- use universal multi-turn extensions for all types of packages, transport packages of various types without re-installing replacement parts (Fig.3,4);
- provide a more reliable fixation of packages, eliminate shock packages when driving a vehicle.

 The technical result is achieved by the fact that in the known device for transporting packages with uranium hexafluoride, the container platform and supporting devices are combined into a single frame (Fig. 5), made in the form of two spinal beams (Fig. 6) with transverse cantilever beams attached to them, and the corner cantilever beams contain fittings for mounting on a vehicle in accordance with the requirements of a single container transport system. Spinal beams are interconnected by spars. Wooden spacers are fixed on the side members, having seats for installing “packages 48”. Supporting elements for “packages 30” are attached to the spinal beams in the form of metal flanged platforms restricting the horizontal movement of packages during loading.

 The cantilever cross beams are equipped with brackets that allow using universal multi-turn stretch marks to fix the packaging. Universal multi-turn stretching consists of a lanyard, which, with a bracket fixed on a cantilever beam, is an integral movable connection, a chain and a detachable bracket attached to the packaging eye.

 For mounting in the so-called. transport position (the device is not loaded with packages) multi-turn extensions on the spine beam are provided with brackets.

 Figure 9 schematically depicts the placement of "packages 48" on an automotive container semi-trailer using the proposed device and using the prototype device.

 The device for transporting packages with uranium hexafluoride is a frame (Fig.6), containing two spinal beams 1 with transverse cantilever beams 2 attached to them, and the angular cantilever beams 3 contain fittings 4 for mounting on a vehicle in accordance with the requirements of a single container transport system. Spinal beams 1 are interconnected by side members 5. On the side members 5, wooden linings 6 are fixed, having seats for installing “packages 48”. Supporting elements for “packages 30” are attached to the spinal beams 1 in the form of metal flanged platforms 7, restricting the horizontal movement of the packages during loading.

 The transverse 2 and corner 3 cantilever beams are equipped with brackets 8 (Fig. 7), on which universal multi-turn extensions are fastened, consisting of a turnbuckle 9, comprising with a bracket 8 mounted on the cantilever beam, an integral movable connection, a chain 10 and a detachable bracket 11, which is attached to the packing eye.

 For mounting in the so-called. transport position (the device is not loaded with packages) multi-turn stretch marks on the spinal beam provided brackets 12.

 For fixing in the working position, the lanyard is equipped with a ratchet handle.

 The proposed device is used as follows.

 The transportation device is installed and fixed on the vehicle in accordance with the requirements of a single container transport system using fittings 4 located in the corner cantilever beams 3. Packages are installed on the appropriate seats: “packages 30” are installed on flanged metal platforms 7, and “packages 48 "- on wooden linings 6. Detachable staples 11 multi-turn stretch marks are fixed on the package. Turnbuckles 9 with the handle with ratchet are transferred to the position of their maximum length. The hooks of the turnbuckles 9 are engaged with the link of the chain 10, providing the maximum possible tightness of the entire extension. Ratchet ratchets 9 are reversed. Stretch marks are tensioned by moving the lanyard handles 9 until all gaps in the stretch marks are completely selected.

 The device is ready for transportation.

 The present invention is a universal design of a device for transporting packages, combining the functions of a container platform and supporting devices. The frame design includes supporting elements for all types of packages (and there are eight of them, subject to modifications).

 The overall length of the device allows the placement of two such devices with two “packages 48” (or five “packages 30”) each on a container train platform, while the device adopted for the prototype contains one “package 48”, and the railway platform can accommodate only three such devices (Fig. 8). Due to the more compact placement of packages on one railway platform, it is possible to transport four large “packages 48” at a time instead of three when using a prototype device, which significantly reduces the unit cost of transportation, increases the efficiency of use of vehicles. When placing packages (usually two “packages 48”) in automobile transport (Fig. 9), an automobile container semi-trailer is used that is shorter than necessary when transporting packages using the prototype device, which improves transport maneuverability and increases transportation safety.

 Since the brackets mounted on the cantilever beams are offset relative to the seats of the “packages (both 30 and 48),” the chains are pulled with a lanyard between the brackets and the eyes of the packages at an angle to the longitudinal and transverse axes of the packages. Therefore, the chains absorb all the loads that arise when the vehicle is moving, and securely fix the package.

 Fastening of packages is carried out only by universal multi-turn extensions (without the use of stops, bolt joints), moreover, once the extensions are fixed on the frame, they allow to fix both “packages 30 and 48”. The laboriousness of packaging fastening processes is reduced.

 The features of the proposed device should also include the fact that all its constituent elements are interconnected and are a single whole. Thus, the possibility of loss or theft of any element is negated.

As shown by the experience of using the first batch, the proposed device has worked well at all stages of transportation:
- transportation without packaging to the place of loading took place without loss of components and weakening their transport position;
- the process of loading and securing packages showed the ease of installation of packages in the seats (large clearance compared to the prototype), the simplicity of working with stretch marks and the absence of the need for additional tools (piles and crowbars for tensioning the lanyards ("package 48"), wrenches ( "packaging 30") for mounting packages on the prototype device;
- transportation of packages to the destination took place without weakening the stretch marks, showing a high degree of reliability of fastening of packages.
