Description

The utility model relates to the field of transport engineering and can be used in the construction of a container for storage and transportation of cylinders with compressed natural gas.

From the description of patent RU 2155681 C1, IPC B60P 3/22, publ. September 10, 2000, the construction of a container for storage and transportation of cylinders with compressed natural gas, which is part of a mobile automobile gas refueling unit (hereinafter - PAGZ), is known. The container is designed for longitudinal (relative to the chassis of the semitrailer) placement of cylinders made in the form of cylinders of considerable length, equipped with two necks.

The container is equipped with a base, coupling clamps holding the cylinders in the transverse direction, as well as front and rear thrust walls to limit the movement of the cylinders in the longitudinal direction. In the thrust walls made holes for the neck of the cylinder.

Cylinders pressed by clamps to the base form a three-dimensional figure in the form of a triangular prism lying on the side face.

The design of the container described above has the following disadvantages.

One of the significant drawbacks of the container design is the possibility of axial rotation of the container during transportation. When the cylinder is axially rotated, there may be a leak in the connection between the cylinder and the process pipe, which is constantly connected to the neck of the cylinder, and, therefore, an uncontrolled gas outlet.

Another significant drawback is the uneven load applied to the cylinders during storage and transportation. The greatest loads are on cylinders located at the bottom of the container. Excessive loads during transportation can lead to deformation of the body of the cylinders and their failure. The service life of the upper and lower cylinders is significantly different.

The disadvantage of the container design is also the inconvenience of maintenance, due to the significant mass of the front and rear thrust walls, which must be removed when replacing the cylinders.

Finally, the design drawback is the increased mass of the container, due to the implementation of the solid walls.

From the description of US patent US 5040933, IPC B60P 3/22; B61D5 / 02 publ. 08/20/1991, the known design of the vertical modules for storage and transportation of cylinders with compressed natural gas that are part of the PAGZ. Each module includes vertical front and rear stop bulkheads with openings for the neck of the cylinders, two vertical rows of cylinders fixed between the stop bulkheads, and devices for protecting the gas cylinder against rotation, including two lock nuts screwed to the threads of each neck of the cylinder on both sides opposite holes in each bulkhead. The modules are mounted close to each other and attached to the frame of the PAGZ semi-trailer; bulkheads are interconnected by their flanges. Replacement of cylinders during operation is performed by disconnecting the module with cylinders from the frame of the semi-trailer and neighboring modules and lifting it together with the cylinders using a lifting device.

Numerous disadvantages of the above-described vertical modules are due to the features of their design.

In particular, the disadvantage of vertical modules is the inconvenience of servicing PAGZ when replacing individual cylinders, due to the need to lift the module with cylinders up to a height exceeding the height of the module. In severe climatic conditions, the dismantling of modules in the open air is not always advisable, and rooms with a ceiling height of at least two times the installation height may not be available.

Another disadvantage of the vertical modules is the inconvenience of service due to the significant mass of the modules, as well as the significant mass of the front and rear stop bulkheads, which must be removed when replacing the cylinder.

Another disadvantage of the vertical modules is the inconvenience of their maintenance as part of the PAGZ, which is due to the impossibility of removing the lock nuts located inside the module and inaccessible to the mounting tool without dismounting the modules.

The most significant drawback of the vertical modules is the fastening of the cylinders only by their necks, which is why the cylinders experience significant loads during storage and transportation, leading to a reduction in the life of the cylinder.

The disadvantage of PAGZ, which includes vertical modules, is the lack of protection against external influences of equipment included in the PAGZ (cylinders, pipelines, etc.).

From the description of US patent US 4784399, IPC B60P 3/22, B61D 5/02, publ. November 15, 1988, the design of horizontal modules for storing and transporting compressed natural gas cylinders that are part of the PAGZ is known. Each module includes horizontal front and rear stop bulkheads with openings for the neck of the cylinders, a horizontal row of cylinders fixed between the stop bulkheads, and gas cylinder protection devices from turning, including two lock nuts screwed onto the thread of each neck of the cylinder on both sides opposite the hole in each bulkhead. The modules are mounted close to each other and attached to the frame of the PAGZ semi-trailer; bulkheads are interconnected by their flanges. Replacement of cylinders during operation is performed by disconnecting the module with cylinders from the frame of the semi-trailer and neighboring modules and lifting it together with the cylinders using a lifting device.

The disadvantages of the modules are due to the features of their design.

The disadvantage of horizontal modules is the inconvenience of their maintenance as part of the PAGZ, which is due to the impossibility of without tightening the modules of tightening the lock nuts located inside the container and inaccessible to the mounting tool.

The most significant drawback of the design of horizontal modules is the fastening of the cylinders only by their necks, which is why the cylinders experience significant loads during storage and transportation, leading to a reduction in the operating life.

The disadvantage of PAGZ, which includes horizontal modules, is the lack of protection against external influences of equipment included in the PAGZ (cylinders, pipelines, etc.).

From the international application WO 2009102168 A2, IPC B60P 3/24, publ. 08/20/2009, the known version of the device to prevent axial rotation of the cylinder, which is part of the PAGZ. The device includes: a persistent bulkhead with a hole for the neck of the container and several small holes for bolts made around the specified hole; a locking nut with a flange screwed onto the thread of the neck of the container, and small holes for bolts are also made in the flange of the above locking nut; bolts and nuts for fixing the flange nut to the thrust bulkhead.

For the closest analogue of the claimed utility model adopted container for transporting cylinders with natural gas, known from the description of patent RU 57687 U1, IPC B60P 3/00, F17C 1/00, publ. 10/27/2006, which includes a metal frame with uprights, walls, doors, as well as cartridges and clamps horizontally located inside the container for holding the cylinders in the transverse direction. Beams of cassettes and coupling clamps in places of contact with cylinders are equipped with gaskets made of elastic polymer material.

One of the significant drawbacks of the design of the container-analogue is the lack of a device to prevent axial rotation of the container and the associated possibility of axial rotation of the container during transportation. When the cylinder is axially rotated, there is a violation of the tightness of the connection between the cylinder and the process pipe connected to the neck of the cylinder, and an uncontrolled gas outlet associated with this.

Another significant drawback of the analogue is the absence of persistent bulkheads restricting the longitudinal movement of the cylinders during transportation of the container. A massive vehicle with sharp accelerations of the vehicle is like a ram.

The disadvantages of the analogue are also the inconvenience of assembling the container and the inconvenience of servicing the container, in particular, the inconvenience of removing the cylinders from the container when they are replaced during operation. The design of the container does not involve the removal of the roof or side metal walls during its operation; installation and fixing of cylinders on cartridges is possible only before installing cartridges in a container, and removal of cylinders only after removing cartridges from a container.

The technical result, which the utility model aims to achieve, is to increase the convenience of servicing a container for storing and transporting compressed natural gas cylinders.

The above technical result is achieved in a container that includes a frame with vertical struts, side walls and doors, rows of horizontal beams and tie clamps to hold the cylinders in the transverse direction, and the beams and tie clamps in places intended to fit to natural gas cylinders equipped with gaskets made of elastic material.

The technical result is achieved by the fact that the container roof is made in the form of a removable tensioning panel, the horizontal beams are made removable, and the container is equipped with front removable and rear vertical persistent bulkheads provided with openings for the neck of the cylinders, and there are gaps between the bulkheads for the installation tool.

The utility model is illustrated by the following images.

In FIG. 1 shows a container assembly with cylinders, with the side walls, roof and doors removed;

In FIG. 2 shows a container frame with vertical struts, horizontal beams and vertical thrust bulkheads;

In FIG. 3 shows a container assembly with side walls and doors.

The positions in the images are indicated by:

1 - cylinder with compressed natural gas;

2 - a coupling collar;

3 - container frame;

4 - a vertical rack;

5 - removable side wall;

6 - a door;

7 - horizontal beam;

8 - front removable vertical thrust bulkhead;

9 - back vertical persistent bulkhead;

10 - the gap between the bulkheads.

The utility model can be implemented in the design of the container, which includes (see Fig. 1-3) a frame 3, vertical posts 4, horizontal beams 7, tie clamps 2, walls 5 and doors 6, and beams 7 and tie clamps 2 in places intended for contact with natural gas cylinders are provided with gaskets made of elastic material.

To implement the utility model, the following changes are made in the design of the container.

The side walls 5 are composite and removable.

Horizontal beams 7 are removable.

The roof of the container (Fig. 1-3 is not shown) is made in the form of a removable stretch panel of a dense waterproof synthetic material. This allows you to install and remove individual containers from the container using a lifting device, such as a hoist.

The container is equipped with front removable 8 and rear 9 vertical thrust bulkheads, in which openings are made for the neck of the cylinders.

Between the bulkheads, gaps are made to establish the installation tool when fixing the neck of the cylinders from axial rotation and to check the quality of the fixing of the neck during operation of the container.

The Assembly of the container and the installation of cylinders with natural gas in the container is as follows.

A welded frame of the container is made of metal beams.

To the frame are connected, for example, by welding, vertical posts 4 and rear vertical persistent bulkheads 9.

Depending on the embodiment of the device for preventing axial rotation of the cylinder, the first lock nuts (for an embodiment of the device with two lock nuts are described, for example, in US Pat. No. 5,040,933), or nuts with flanges (for an embodiment of a device for preventing axial rotation of a cylinder given in WO 2009102168 A2).

Install and connect with the racks 4 the bottom row of removable horizontal beams 7.

Install cylinders 1 (4 pieces) on the bottom row of removable horizontal beams 7, so that the neck of the cylinders go into the corresponding openings of the bulkheads 9, and fix the cylinders 1 with coupling clamps 2.

Check the accuracy of the installation of the cylinders 1 of the bottom row.

Then install and connect with the uprights 4 the second row of horizontal beams 7.

Install on the second row of horizontal beams the next tier of cylinders 1 (4 pieces) so that the neck of the cylinders go into the corresponding holes of the bulkheads 9, and fix them with tie rods 2.

Check the accuracy of the installation of cylinders 1 of the second row.

Then perform the same operations for the third and fourth tier of cylinders 1.

Install the front vertical thrust bulkheads 8 and connect them to the frame of the container with removable threaded connecting elements.

Fix the neck of the cylinder 1 from the rotation. Depending on the used embodiment of the device for preventing axial rotation of the cylinder, the necks are fixed by screwing the second lock nuts onto them or by screwing the flange to the thrust bulkhead using threaded bolt-nut pairs.

Pipes are connected to the necks of the cylinders 1.

Install removable side walls 5 and the roof of the container, made in the form of a removable tension panel.

Attach to the frame of the container door 6.

The container is ready for transportation of natural gas cylinders as a part of any vehicle adapted for its placement. In particular, the container can be used as part of PAGZ.

The container assembly with cylinders is operated in a known manner.

If it is necessary to replace the cylinder, remove the roof and side walls 5, open the doors 6, disconnect the pipelines, remove the vertical thrust bulkheads 8, then disconnect the clamps and first remove the upper level cylinders through the top of the container, then removable horizontal beams 7, then the cylinders of the next level and etc.

The manufacture and operation of a prototype container confirmed the industrial applicability of the utility model and its compliance with the claimed technical result.

Improving the convenience of servicing the container is achieved, in particular, due to the presence of removable side walls, which allows to improve access to the internal parts of the container - places of attachment of horizontal beams, tie clamps. Performing gaps between bulkheads simultaneously reduces the mass of bulkheads (and thereby facilitates assembly of the container and removing the cylinders during operation) and allows visual access and access of the mounting tool to the device nuts to prevent axial rotation of the cylinder located inside the container behind the bulkheads.

Improving the convenience of replacing cylinders during operation is achieved by making the roof in the form of a removable tension panel, as well as by making removable side walls, horizontal beams and front thrust partitions.

The advantages of the container design are increased operational safety and increased cylinder life. The conducted patent studies confirm the world novelty of the utility model.
