Description

The invention relates to mechanical engineering and can be used to install a tank of gas fuel, which I use liquefied natural gas (LNG) on a vehicle.

A KAMAZ gas-powered dump truck is known in which a liquefied natural gas cylinder is mounted on a lodgement for a standard fuel tank (see KAMAZ on liquid methane: all details. Internet page https://avtospravochnaya.com/avtomobili/7001 , publ. 05.24.2017).

This solution assumes that the engine runs only on gas fuel and does not allow the engine to run on a mixture of diesel and gas fuels. In addition, this solution is not intended for quick, multiple removal and installation on a vehicle. Therefore, to service such a vehicle, it is necessary to have boxes (garages) that are equipped with gas safety equipment.

A device is known for fastening a tank with liquefied gaseous fuel on a vehicle, containing lodgements fixed on the frame, and couplers for fixing the tank from below on lodgements (RU 36648 U1, 03/20/2004).

The disadvantage of this device is the low reliability of fastening the LNG tank of large weight and size from the bottom using screeds.

Closest to the proposed device is a device for attaching gas cylinders to a vehicle, containing transverse elements interconnected by a longitudinal coupler, mounted on the transverse elements of the lodgement and fixing elements of gas cylinders in the lodgement, while the transverse elements are made in the form of L-shaped brackets, having a U-shaped cross-section with outward-facing sides and hardened from the side of attachment to the vehicle frame by amplifiers, and gas cylinder fixation elements are clamps with gaskets (RU 167791 U1, 01/10/2017).

This device is designed to mount gas cylinders with clamps and does not provide the ability to quickly remove and install the LNG tank from the vehicle repeatedly.

The technical problem solved by the invention is to create a device for attaching the LNG tank, which allows you to quickly install and fix the tank, as well as quickly remove it.

The technical problem is solved by a device for attaching a tank for liquefied natural gas to a vehicle, comprising a carrier assembly for attachment to a vehicle frame and two consoles connected to it with mounting means located thereon in the form of a rotary lock, wherein the carrier assembly has in the middle part between the consoles have a protrusion, on which the fastening means in the form of a rotary lock is also located.

In a preferred embodiment, the supporting unit is made in the form of a frame with a central pillar, which is connected at one end to a beam, to which the consoles are connected, and at the other end, to two inclined elements, also connected to the consoles.

In this case, the protrusion with the fastening means is located at the junction of the central rack with the beam.

In addition, it is advisable that the guide plates are attached to the consoles at the place of their connection with the bearing assembly.

The invention is illustrated by drawings.

In FIG. 1 shows the proposed device, front view.

In FIG. 2 - the same, top view.

In FIG. 3 - same side view.

In FIG. 4 shows the proposed device when installing an LNG tank on it.

In FIG. 5 - the proposed device with a fixed LNG tank.

In FIG. 6 - a fragment of the LNG tank with a twistlock fixed on it.

The device for mounting the LNG tank on the vehicle frame is made in the form of a bracket, which includes a bearing unit 1 and two consoles 2 mounted on it (Fig. 1-3). The bearing unit 1 is a frame that includes a central post 3, to which a horizontal beam 4 is attached at the bottom, connected at its ends to the ends of the consoles 2, and at the top, inclined elements 5, which are connected at their ends through short vertical elements 6 sec the ends of the consoles 2. At the junction of the central rack 3 with the horizontal beam 4, a protrusion 7. A support assembly 1 is not limited to the described construction. It may have a different design adapted to the frame of a particular vehicle.

Fastening means are installed on the consoles 2 and on the protrusion 7, preferably in the form of rotary locks - twist blocks 8. The device for attaching the LNG tank is mounted on the vehicle frame by means of an adapter flange.

To the consoles 2 in the place of their connection with the bearing unit 1 are attached guide plates 9, which are slightly bent in opposite directions.

On the bottom of the LNG tank 10, response windows 11 are made for accommodating the conical heads 12 of the twist blocks 8 (FIG. 6). When installing the LNG tank 10, the forklift forks are inserted into the guides in the lower part of the tank 10 body until they stop in the limiters, raise the forks to the required height, bring the LNG tank 10 to the vehicle, lower the LNG tank 10 down to align the guides with the consoles 2. At the same time, the plates 9 ensure the correct orientation of the LNG tank 10 relative to the consoles 2. When lowering the LNG tank 10, the response windows 11 of the LNG tank body 10 and the conical heads 12 of the twistlocks 8 are combined. The screw clamps 13 of the twistlocks 8 are fixed, which rotate the conical heads 12 of the twistlocks 8.

The design of the device allows you to perform operations for multiple removal / installation of the LNG tank on the vehicle frame in the case, for example, of scheduled maintenance in rooms (garages) that are not intended for the presence of equipment with gas fuel. If the LNG tank is removed, it can be stored at a special site. The device can be used to install the LNG tank on various vehicles that are operated in the mixed fuel mode (for example, gas-diesel mode) and can only work on diesel fuel in case of removing the LNG tank.
