Description

The utility model relates to the field of transport engineering and can be used in the design of a device for attaching compressed gas cylinders to a car when retrofitting a car with gas equipment.

From the prior art, for example, from the description RU 180697U1, IPC B60K 15/07, publ. 06/21/2018, the known design of a device for attaching a compressed gas cylinder to a car, including a support frame formed by two longitudinal and two transverse beams.

The design is not designed to hold two compressed gas cylinders.

From the prior art, see the description of patent application CN 102941804 A, IPC B60K 15/07, publ. 02/27/2013, the known design of a device for attaching two compressed gas cylinders to a car, including a welded support frame formed by 4 longitudinal and 4 transverse beams and 16 posts. Welded to the longitudinal beams are two lower arcuate metal strips in plan, which form a bed for compressed gas cylinders.

Disadvantages of the design are:

- high labor intensity of manufacturing due to the use of welding of frame elements;

- the use of massive square pipes for the manufacture of beams;

- low reliability of fastening of cylinders, due to the absence of means of limiting the longitudinal movement of cylinders.

For the closest analogue of the claimed utility model, the design of a device for attaching a compressed gas cylinder, known from the patent description CN 206465773 U, IPC V60K 15/07, publ. 05.09.2017, including two vertical steel walls 2.5 mm thick and two longitudinal steel beams of square cross-section, installed in square holes of vertical steel walls and welded to the vertical walls. Two lower metal strips, arched in plan, are welded to the longitudinal beams, which form a cradle for a compressed gas cylinder.

In contrast to the design known from patent application CN 102941804 A, the analog device is equipped with means for limiting the longitudinal movement of the balloons, made in the form of holes in the walls with a diameter smaller than the outer diameter of the cylindrical part of the balloon. The disadvantages of the analog design are:

- high labor intensity of manufacturing, due to the need to weld vertical steel walls with beams and a large range of parts;

- low manufacturability of the structure, due to the use of closed-section pipes;

- low reliability of the cylinder attachment due to poor fit of the longitudinal beams to the cylindrical part of the cylinder body with compressed gas;

- excess thickness of vertical steel walls;

- the use of square pipes for the manufacture of beams;

- impossibility of placing two cylinders with compressed gas.

The task to be achieved by the utility model is to create a design of a device for attaching two compressed gas cylinders to a car, which is characterized by reduced labor intensity and increased manufacturability.

The technical results to be achieved by the utility model consist in reducing the labor intensity of manufacturing, increasing the manufacturability of the device design and increasing the reliability of fastening compressed gas cylinders to a car.

The above technical results are achieved in a device for attaching compressed gas cylinders to a car, which includes vertical walls connected by longitudinal beams.

The specified technical results are achieved by the fact that the beams are made in the form of a section of a steel U-shaped cross-section, the ends of which are provided with central protrusions bent at right angles to the inside of the profile, mounting holes are made in these central protrusions and vertical walls, and the beams are connected to vertical walls with threaded fasteners. In this case, the longitudinal beams are oriented with the outer surface of the middle part inside the device and form cradles for the cylindrical parts of the cylinder bodies. In this case, the mounting holes in the vertical plates are oval in shape. The utility model is illustrated by the following pictures.

FIG. 1 shows a device for attaching a compressed gas cylinder, selected for the closest analogue.

FIG. 2 shows the inventive device for attaching two compressed gas cylinders.

FIG. 3 shows a longitudinal beam with rectangular central projections.

FIG. 4 shows the device assembled with cylinders.

Positions in the Figure indicate:

1 - device for fastening compressed gas cylinders;

2, 3 - vertical wall;

4, 5, 6, 7 - the lower longitudinal beam of the U-shaped cross-section;

8, 9 - upper longitudinal beam of U-shaped cross-section;

10 - threaded fastener;

11, 12 - compressed gas cylinder.

The utility model (see Fig. 2) can be implemented in the structure of the device 1, which includes vertical walls 2, 3, connected by longitudinal beams.

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

The longitudinal beams 4-9 are made in the form of a section of a steel U-shaped cross-section.

At both ends of the section of the steel U-shaped cross-section, central protrusions are formed, which are then bent at right angles to the inside of the profile.

In the simplest case, the central protrusions are rectangular in shape, which does not exclude the possibility of their implementation in another shape other than rectangular (for example, in the shape of an isosceles trapezoid).

In the central protrusions of the longitudinal beams 4-9, as well as in the vertical walls 2, 3, in the places provided for joining the walls with the longitudinal beams, mounting holes are made. To regulate the pressure of the cylinders 11, 12, the mounting holes in the vertical walls, intended for fixing the longitudinal beams, are oval in shape.

Beams 4-9 are connected to vertical walls 2, 3 using threaded fasteners 10.

The longitudinal beams 4-9 are divided into two groups 4, 5, 8 and 6, 7, 9, oriented with the outer surface of the middle part of the U-shaped profile inside the device 1 and attached to the vertical walls 2, 3 so that each of these groups of longitudinal beams formed a lodgement for the cylindrical part of the body of the corresponding cylinder 11, 12 with compressed gas.

Reducing the complexity of manufacturing, increasing the manufacturability of the device design are achieved due to:

- rejection of welded connection of longitudinal beams with vertical walls;

- using a bent profile instead of a pipe, making vertical walls and longitudinal beams using cold stamping on universal equipment;

- making oval mounting holes in vertical walls by stamping;

- reducing the range of parts (replacing arched metal strips with longitudinal beams, making all longitudinal beams the same).

At the same time, the proposed change in the design of the device makes it possible to increase the reliability of fastening the cylinders, since due to the execution of mounting holes in the vertical walls of an oval shape and the refusal of welding to connect the vertical walls and longitudinal beams, when assembling the device, a tight fit of the longitudinal gas.

The device is used as follows.

The upper longitudinal beams 8, 9 are removed by unscrewing the corresponding threaded fasteners 10.

In the internal cavity of the device 1, limited by vertical walls 2, 3 and longitudinal beams 4-7, two cylinders 11, 12 with compressed gas are placed successively.

Install the upper longitudinal beams 8, 9 and screw them to the walls 2, 3 using threaded fasteners 10. In this case, the cylinders 11, 12 are clamped between the corresponding three longitudinal beams.

The longitudinal movement of the balloons is limited by the edges of large-diameter holes made in the vertical walls of the device.

The creation and operation of prototypes of the device confirmed the possibility of achieving the declared technical results and the industrial applicability of the utility model.
