Description

Title: Liquid gas container frame assembly and method for manoeuvring said assembly

FIELD OF THE INVENTION

The present invention relates to a liquid gas container frame assembly and to a method for manoeuvring said assembly.

SUMMARY OF THE INVENTION

Liquid gas for mid to high range use is generally transported in tanks with a volume of 1000 liters or more. These large tanks are only allowed to be transported empty. Once the tank is placed at its desired location, the tank needs to be filled by means of a separate tank vehicle. When the tank needs to be moved, it needs to be emptied first, for example by the tank vehicle which removes the gas before the tank can be moved by means of for example a crane vehicle. Also, only trained personnel is allowed to handle the tanks and connect gas lines to them. The transport and installation of the tanks Is cumbersome, costly and time consuming. This is especially a drawback when the tank is intended for short time use, such as at festivals, weekend events, one time gatherings, for example a music festival held in a large field or in situation wherein only for a short period of time gas is needed, for example as temporary gas supply during building or renovation of a house. Providing liquid gas to festivals or houses is particularly difficult since these festivals are often hosted at outdoor locations, far removed from roadways, and houses are located in residential areas for which certain environmental and restrictions apply. Neither trucks transporting the tanks nor tank vehicles are then able drive up to the installation location, where the tank is to be connected to a gas powered utility. Regulations prohibit refilling by a tank vehicle in the presence of crowds, preventing refilling during the festival. Alternatively, smaller gas bottles can be used, but regulations require these to be fastened. At festivals there is often no fixed structure to affix the bottles to. Also the volume of these bottles is limited (less than circa 115 liter) requiring continuous changing and (dis)connecting of the bottles, resulting in an increased risk.

It is therefor an object of the present invention to provide an improved liquid gas container assembly wherein at least some of the abovementioned disadvantages are resolved.

More in particular, is it an object of the present invention to provide an improved liquid gas container assembly which can be safely and conveniently maneuvered and installed, especially for temporal use in hard to reach locations.

According to a first aspect of the present invention, a liquid gas container frame assembly is provided. The assembly comprises a container for liquid gas with an internal volume circumscribed by a circumferential wall. The internal volume of the container is at least 150 liter. The wall is substantially parallel to a central axis of the substantially longitudinal container. On the container fittings are provided for connecting a gas line thereto for use and filing of the gas in the container, when the assembly is installed on a installation location.

The assembly further comprises a frame for transporting the container in a secure manner. The frame comprises a plurality of longitudinal beam elements which extend substantially parallel to the central axis of the container during use. During use here indicates the assembled state of the container, wherein the frame surrounds and protects the container. The longitudinal beam elements are positioned spaced apart from one another circumferentially around the container during use. The frame further comprises reinforcing beam elements which are connected to the longitudinal beam elements, such that during use the longitudinal beam elements and the reinforcing beam elements form a frame enclosing the container. The surrounding frame is arranged to protect, to a certain degree, the container from impact by other objects or the ground. Securing elements are provided in the frame to fasten the container to the frame. The frame supports and stabilizes the container to prevent it from falling over. This intrinsic stability of the assembly eliminates the need to secure the container to a fixed structure, such as a wall, and makes the assembly safe to use.

Finally the frame comprises manoeuvring means which allow a user to manoeuver the assembly with the container filled with liquid gas. The manoeuvring means are arranged to move the container a limited distance after the container has been transported to an offloading location by a transport vehicle. This offloading location is usually near a road, whereas the installation location, where the container is to be connected to an installation, is some distance away from the road and cannot be reached by the transport vehicle. This is for example the case when the installation location is a festival tent located in some grassy or muddy field. The user can manoeuver the container in the assembly the short distance to the installation location by the manoeuvring means. Thus, hard to reach locations can conveniently be reached with the assembly according to the present invention. Due to the frame protecting the container, the manoeuvring proceeds in a safe manner. Thereby the object of the present invention has been achieved.

In an embodiment the length of the longitudinal beam elements exceeds the length of the container along the central axis, such that the frame extends beyond and around the fittings for protecting the fittings from impacts. Preferably the frame is substantially rectangular to optimize packing of multiple assemblies on a transport vehicle.

In an embodiment the manoeuvring means are arranged for manually manoeuvring the assembly. A user can thus manoeuver the assembly by hand, without the need for additional transport devices such as forklifts or carts. Preferably the manoeuvring means comprise at least two wheel axis openings, each of which is provided in a different longitudinal beam element. Each opening forms a bore through a longitudinal beam element and the bores are aligned with respect to another. A wheel axis can thus be inserted through the at least two wheel axis openings/bores. During use the wheel axis extends substantially perpendicular to the central axis. The wheel axis is spaced apart from the container. Thus a user can quickly and easily assemble the frame into a manoeuvring device for moving the container a short distance. This allows for an easy and fast installation or repositioning of the container for example when a container runs out of liquid gas.

In an advantageous embodiment the position of the wheel axis openings corresponds to the position of the centre of mass of the assembly, or in an alternative embodiment the position of the wheel axis openings are located near the centre of mass of assembly. The centre of mass can correspond to the assembly with either the filled or empty container. During manoeuvring the centre of mass of the assembly is thus located above (or optionally below) the wheel axis, such that the assembly is evenly balanced on either side of the wheel axis, similar to a seesaw. The weight the assembly exerts on a user is then greatly reduced, allowing for easy manoeuvring of the wheeled assembly.

In an embodiment the wheel axis openings are disposed at the top and/or bottom side of the frame. When the wheel axis is provided at solely the top or bottom side, the assembly can be transported by lifting up the other side of the assembly, similar to a wheelbarrow. By providing wheel axes at both the top and bottom side a balanced wheeled assembly is achieved. This latter assembly can comprise at least three or four wheels. Optionally one or more wheels can be pivotably connected to the wheel axis or frame for increasing the manoeuvrability of the frame. Additionally stearing means can be provided. In an embodiment the assembly further comprises the wheel axis which is provided with one or more wheels.

In an advantageous embodiment the manoeuvring means further comprise at least one lever. This lever is slideably connected to the frame by bearings, such that the lever is able to move parallel to the central axism e.g. as a sliding bar. The at least one lever is moveable between an inner position positioned substantially within or against the frame or container. In the inner position the lever is stored and does not extend substantially beyond the frame. For use the lever is translated to an outer position wherein the bar extends partially outside the frame. The lever extends from the frame in the longitudinal direction (parallel to the central axis), such that a user can easily grip the lever. The lever thus provides a handle which allows the user to manoeuver the assembly. This embodiment is especially advantageous when combined with the embodiments applying a single wheel axis (the seesaw and wheelbarrow embodiments). The lever allows a single user to manually manoeuver and steer the assembly in an efficient manner. Preferably two levers are applied symmetric with respect to one another,allowing a user to grip one with each hand. In an embodiment lever securing elements are provided for securing the at least one lever to the frame. The bar is thus unable to move in at least the inner and outer positions to improve the safety of the assembly.

In advantageous embodiment the longitudinal beam elements are connectable to the reinforcing beam elements in a detachable manner, and fixed by locking means/elements. For example bolts can be used to affix the longitudinal beams to the reinforcing beams during use. In this manner the frame can easily be disassembled when the container requires maintenance or inspection. Alternatively, the longitudinal beam elements can be fixed to the reinforcing beam elements to provide a sturdy construction. Welding or other known permanent bonding methods can be applied.

In an embodiment the frame further comprises hoisting elements, e.g. hoisting eyes, for easy (off)loading of the assembly. Preferably the frame further comprises recesses or openings in the longitudinal beams for forklift forks. This allows the assembly to be easily loaded of the transport vehicle at the offloading location.

In an embodiment the frame further comprises vehicle securing elements. During transport on the transport vehicle the frame needs to be affixed to the vehicle for safety. To this end arrester hooks and/or locking pin openings can be provided in the frame. The arrester hooks and the locking pin openings are arranged to engage a corresponding locking element on the transport vehicle. The hooks can engage a pin or opening while the openings are affixed via a pin connected to the vehicle. This allows for a quick and secure attachment of the assembly to the transport vehicle. Preferably the positions and dimensions of the vehicle securing elements on the frame correspond to standardized dimensions of commonly used securing elements on transport vehicles.

From the state of the art generally two types of liquid gas containers are known: bottles with maximum volume of 115 liters and tanks with a volume of at least 1000 liters. The ADR treaty (Accord européen relatif au transport international des marchandises Dangereuses par Route) of 2013 prescribes strict regulations for the transport of large volumes of gas. The ADR (specifically paragraph 1.1.3.6 the ADR treaty published by the Dutch government on 19-2-2013) yields an exception for the transport regulations of dangerous (liquid) gasses with limited volumes. This is generally known as the “1000 point rule”.

The container according to the present invention has an internal volume of at least 150 liters. The container is designed to comply with the “1000 point rule” and is thus allowed to be transported while containing (liquid) gas. Preferably the internal volume is between 150 liters and 333 liters. For liquid gasses specifically the internal net volume is around 325 or 333 liters, which is close to the maximum volume allowed by the ARD treaty. Thus the container according to the present invention distinguishes itself from the commonly known tanks in that the container is allowed to be transported while containing liquid or gas, according to the ADR. The container distinguishing itself, amongst others features, from the commonly known gas bottles by its internal volume, which makes the container suited for mid to large scale operations, whereas the bottles are meant for limited use. Due to the frame the assembly needn’t be affixed to a fixed structure, unlike the gas bottles. After positioning the assembly into the installation position, the assembly is stabilized and as such immediately ready for connecting a gas line thereto. Thus the installation time and effort for the assembly is reduced with respect to the use of gas bottles or tanks.

In an embodiment the container further comprises a contents gauge. The gauge indicates the remaining volume of liquid gas contained in the container. Liquid gas inside the container continually vaporizes and thus the container is kept at the vapour pressure of the liquid gas. Hence, a simple pressure meter cannot be used to determine the volume of liquid gas remaining in the container. A contents meter as generally applied in the tanks can be applied to the container according to the present invention. Preferably the container comprises an ullage valve or a pressure relief valve. Specifically a manually operated 80% ullage valve is used in a preferred embodiment. Ullage valves are commonly known from e.g. LPG applications.

In an embodiment the container is arranged for use in a substantially horizontal orientation, while the assembly is arranged for transport in a substantially horizontal orientation. Horizontal here indicates the orientation of the central axis of the container. Preferably the container is a pressure container, preferably for propane or LPG. The container is conform the regulations of the ADR, e.g. provided with a test pressure of 30 bar.

The invention further relates in a second aspect, to a frame or a container for use in a liquid gas container frame assembly according to the present invention. Such a container or frame have been described in the previous paragraphs.

The invention further relates, in a third aspect, to a method for transporting a liquid gas container frame assembly according to the present invention. In a step of the method the assembly with the filled container is offloaded from a transport vehicle at the offloading location. The assembly can be hoisted off the vehicle by the hoisting eyes or by means of a forklift. In a next step the assembly is manoeuvred from the offloading location to an installation location by means of the manoeuvring means. Preferably prior to the manoeuvring step an additional step of inserting the wheel axis through the at least two wheel axis openings of the manoeuvring means is performed. The wheel axis is then oriented substantially perpendicular to the central axis and spaced apart from the container. At the installation location the gas line is connected to the fittings. By applying the method according to the present invention a hard to reach gas powered facility can be easily provided with gas.

Preferably the method comprising the further steps of sliding the at least one lever from an inner position positioned substantially within the frame to an outer position wherein the bar extend partially outside the frame. In another step the at least one lever is affixed in the outer position.

DETAILED DESCRIPTION OF THE DRAWING

Fig. 1 schematically shows a side view of a liquid gas container frame assembly 1 according to the present invention. The assembly 1 in Fig. 1 comprises a container 10 for liquid gas and a frame 20 for secure/safe transport of the container 10 in the frame 20.

The container 10 is a longitudinal container 10 with a circular cross-section. A circumferential wall 11 runs substantially parallel to a central axis A of the container 10 and circumscribes the inner volume of the container 10. The net volume is between 150 and 333 liter to comply with the “1000 point rule”. For liquid gasses the internal volume is preferably around 325 or 333 liter. The container 10 is designed as a pressure container 10, and is preferably designed according to the common standards for LPG or propane containers. Metal such as steel can be used for producing the container 10. The container 10 preferably has a test pressure of 30 bar and is designed in accordance with the P200 packaging instruction of the ADR treaty. An ullage valve or a pressure relief valve is provided on the container 10 in Fig. 1. By means of a contents meter a user can determine the remaining liquid gas volume in the container 10. Fittings 12 are provided on the top side of the container 10 for connecting a gas line, so that gas can be transported from the container 10 to a desired gas powered utility. The bottom side 13 of the container 10 in Fig. 1 is curved outwards. In Fig. 1 the container 10 is enclosed in a frame 20, which allows for a stable positioning of the container 10. The frame 20 also protects the container 10 from impacting with other objects and makes stacking of multiple containers 10 possible.

The frame 20 further comprises a plurality of longitudinal beam elements 21 which extend substantially parallel to the central axis A of the container 10. The longitudinal beams 21 are spaced apart from one another circumferentially around the container 10 by reinforcing beam elements 22. The longitudinal beam elements 21 and the reinforcing beam elements 22 form a rectangular frame 20 enclosing the container 10. In Fig. 1 the longitudinal beam elements 21 are longer than the container 10, while the reinforcing beam elements 22 are wider. The container 10 is thus fully enclosed by the beam elements 21, 22. Preferably the beam elements 21, 22 are steel beams, preferably massive bars, with a rectangular or circular cross-section. Alternatively the beam elements 21, 22 can be provided with a profile, such as I, H, U, or other profiles.

Locking elements 23 are provided near the corners of the frame 20 in Fig. 1. The locking elements 23 affix the beam elements 21,22 to one another to form the rigid frame 20. By unlocking the locking elements 23 the frame 20 can be disassembled and removed from the container 10. This allows simple access to the container 10 for maintenance, inspection, testing and certification. In Fig. 1 the locking elements 23 are bolts and nuts 23, but other commonly known locking mechanisms such as locks, latches, or clamps, can be applied within the scope of the present invention.

Fastening means 30, e.g. securing elements, tie down straps, lashing straps, are connected to the frame 20 to affix the container 10 to the frame 20. In Fig. 1 the securing elements 30 are ring-shaped clamps surrounding the container 30. The frame 20 protects the container 10 from tilting over. Tensioning means are provided to properly fix the container 10 in the frame 20. There is no need to affix the assembly to a wall, since the frame 20 provides sufficient support and protection for the safety of the container 10.

Manoeuvring means 24, 25, 26, 32 are provided on the frame 20. This allows a user to manually move the container frame assembly 1 without requiring an additional lifting vehicle. The manoeuvring means 24, 25, 26, 32 can be comprised of at least two wheel axis openings/bores 24, 25, 26. A first opening 24, 25, 26 of a pair of openings 24, 25, 26 is provided on a different longitudinal beam element 21 than a second opening 24, 25, 26 of the pair, such that both openings 24, 25, 26 are aligned with another. As such a wheel axis 34, 36, 38 can be inserted through the at least two aligned wheel axis openings 24, 25, 26. One pair of openings 34 is positioned in correspondence with the centre of mass of the assembly 1. This can be either the centre of mass of the assembly 1 with a fully filled container 10 or completely empty container 10. Openings 36 are provided near the edge between the top and bottom (left and right respectively in Fig. 1) side of the frame 20, while openings 38 are provided near the lower corners of the frame 20 in Fig. 1. Top and bottom here are in reference to the central axis A. Top side is defined as the end of the frame 20 near the fittings 12, while the bottom side is the end of the frame 20 near the bottom side 13 of the container 10.

For conveniently lifting the assembly 1 on or off a transport vehicle, the frame 1 is provided with hoisting means, such as hoisting eyes 29 and/or openings 28 for forklift forks. The hoisting eyes 28 are connected to the upper side of the frame 20 in Fig. 1, whereas the openings 28 are provided near the under side in Fig. 1. Preferably the hoisting eyes 29 are arranged to allow stacking of multiple assemblies 1 according to the present invention by for example positioning the hoisting eyes 29 slightly inward of the upper side beams elements 21, 22 in Fig. 1. The rectangular forklift openings 28 are positioned on either side of the centre of the assembly 1 to improve stability during lifting. Not shown in Fig. 1 is that forklift openings 28 in opposite beam elements 22 are aligned with one another.

On the bottom side the frame 20 further comprises vehicle securing elements 27, 39 for securing the frame 20 to a transport vehicle. In Fig. 1 so called Trio openings 27 are provided in the lower beam elements 21. The openings 27 correspond to locking elements on the transport vehicle. The frame 20 is locked to the vehicle by engaging the opening 27 with the locking element, for example by sliding a pin through the opening and securing the transport vehicle.

Fig. 2 schematically shows a side view of a liquid gas container frame assembly 1 according to the present invention with a wheel axis 33 inserted in wheel axis opening 34 in the frame 20. The wheel axis 33 runs substantially perpendicular to the central axis A. The container 10 is located at a distance from the wheel axis 33, so that rotation of the wheel axis 33 can proceed unhindered. Opening 34 is positioned below the centre of mass of the assembly, such that the assembly 1 can be balanced on the wheel axis 33, like a seesaw.

Assembly 1 further comprises a lever 32 as part of the maneuvering means 32, 33, 34. The lever 32 is moveable from an inner position 32’ to an outer position, as indicated by 32 in Fig. 2. Bearings 31 connect the bar 32 to the frame 20 and allow its sliding motion. Preferably the bar 32 is shorter than the frame 20, such that it 32 can be stored inside the frame 20 along the container 10. Hereto the bearings 31 are positioned on the beam elements 21 on the inside of the frame 20. Lever securing elements (not shown) are provided for securing the one or two levers to the frame 20. A pin for example can be slid through the bar 32 into the frame 20 or bearing 31 to affix the bar 32 in at least the inner (32’) and outer position (32). The lever 32 or bars 32 can be easily gripped by a user for manoeuvring the assembly 1. Since the centre of mass is located above the wheel axis 33 the user requires little effort to lift the assembly 1. The lever 32 can be used to easily steer the assembly 1 in a desired direction.

Fig. 3 schematically shows a side view of a liquid gas container frame assembly 1 according to the present invention with a wheel axis 35 inserted in wheel axis opening 36 in the frame 20 at the top side of the container 10. Similar to Fig. 1 the lever 32 is extended for conveniently handling the assembly 1. The wheel on the wheel axis 36 is smaller than the wheel in Fig. 1 and located on the top side of the frame 20. The wheel axis 36 can also be provided at the bottom side of the assembly 1. The assembly in Fig. 2 can be handled similar to the commonly known wheelbarrow, allowing for easy maneuvering by the user.

The assembly 1 thus comprises wheels at its top and bottom side, such that the assembly 1 is supported by the wheels 38 in a stabilized manner. The number of wheels 38 at the top can be equal to that at the bottom of the assembly 1. Alternatively, two wheels 38 can be present at the bottom side and one wheel 38 at the top or vice versa. In am embodiment one or more wheels 38 are pivotable to easily steer the assembly 1.

Figure 5 schematically shows a bottom view of a liquid gas container frame assembly 1 according to the present invention. Fig. 5 illustrates the rectangular shape of the frame 20, enclosing the circular container 10 with bottom side 13. The length of the reinforcing beam elements 22 in Fig. 5 is longer than the diameter of the container 10. The securing elements 30 with the tensioning elements fixes the container 10 to the frame 20. The securing elements 30 comprise a strip running over the top side of the container 10 from a tensioning element on the left side to a tensioning element on the right side of the container 10. The securing elements further comprise profiles which support the circumferential wall of the container 10.

Fig. 5 demonstrates the rectangular outer shape of the assembly 1 which allows multiple assemblies to be stacked and packed in an efficient manner. The hoisting eyes 29 are positioned inwards of the beam elements 21, while the bearings 31 for the lever 32 are located on the inside of the frame 20.

Fig. 6 schematically shows a top view of a liquid gas container frame assembly 1 according to the present invention. Fig. 6 demonstrates the rectangular shape of the frame 20 and the positioning of the bearing 30 of the lever 32. The vehicle securing elements further comprise arrester hooks 39, which are arranged to be slid over securing bars on the transport vehicle. This allows the assembly 1 to be affixed to the vehicle.
