Description

The utility model relates to transported means providing gas supply to consumers, in particular compressed natural gas, with refueling without a booster compressor.

Known transported gas filling units from RF patents for utility models No. 53634, No. 79499 and inventions No. 2381920, No. 2383453.

Each technical solution from the listed patents contains a mobile gas refueling unit - a semitrailer transported by truck. Such a gas refueling unit turns off the carrier frame with cassettes with gas cylinders located on it, while the frame rests on the support posts (in their working position), made with the possibility of bringing into transport position. Cassettes are structures formed by power racks and horizontal elements on which gas cylinders are laid.

When using the known mobile transported gas refueling units, disadvantages are found.

In particular, a semitrailer with gas cylinder cartridges refers to complex devices due to the design of the semitrailer itself, which contains a wheel module with suspension, braking means, a coupling unit with a tractor.

As the closest analogue to the claimed utility model selected technical solution according to the patent of the Russian Federation No. 2383453.

The problem, which the utility model is aimed at, is to expand the arsenal of tools for this purpose while simplifying the device.

The objective is achieved by the fact that the transported gas filling unit includes a supporting frame with spars, cross members and support legs in a working vertical position, adapted to bring into a transport position, cassettes with gas cylinders also installed on the supporting frame, while the supporting frame is intended for installation on chassis of the truck.

In the proposed gas refueling unit:

- each cartridge is made in the form of a box-like frame with walls located along the edge of the corresponding side member, gas cylinders are installed so that the body of each gas cylinder rests on the surface of the holes that are present in the walls and are located as close as possible to each other, and the cartridges are interconnected from above by bolted connection fastening the upper belt of the frame.

- the cross-pieces are intermediate cross-members located between two end cross-members, to which four support legs are connected, and the end cross-members are made with protruding parts extending beyond the side members and having a trough-like profile open towards the edge, a housing is installed on the outside of each protruding part the corresponding worm gear, providing vertical rotation of the support rack between the working vertical position and the transport vertical position, the connection of the support posts with the cross member is organized through the L-shaped connecting elements, each of which is a continuation of the corresponding support post and enters with its free end into the indicated open profile of the protruding part, the output shaft of each worm gearbox extending across the protruding part is connected to the free the end of the corresponding connecting element.

- support racks are made with the possibility of height adjustment.

- the distance between the support racks in the upright working position is selected from the condition of ensuring free entry / exit of the truck chassis under the carrier frame and from under the specified frame.

The essence of the utility model is explained as follows.

The installation of cassettes with gas cylinders on a supporting frame with support racks made with the possibility of bringing them into a working vertical position and transport position, determines a new design and layout solution of the transported gas refueling unit, expanding the range of well-known mobile gas tankers.

As a cartridge for gas cylinders, any known means can be used, including a cartridge with a frame and walls having openings for installing gas cylinders, described in RF patent No. 159348 for a utility model. The use of such cassettes in the inventive device brings the benefits due to its design. Thus, the implementation of cartridges in the form of a box-shaped frame with parallel walls having openings located as close as possible to each other, makes it possible to place the body of each gas cylinder on the surface of two opposing openings. The condition for the closest possible location of the holes on one wall follows from the need for storage and transportation of gas cylinders separated by spacers. Based on this need, continuous fragments of the surface of the walls between the holes act as spacers.

The orientation of the interconnected cartridges with gas cylinders with the arrangement of the walls of the cartridges along the side members determines the formation of a raft, which can be considered as an integrated cartridge. In this case, the frame of each cartridge is a traditional metal construction with uprights, longitudinal and transverse crossbars (relative to the elements of the supporting frame); there are lateral connections on the sides of the frame for rigidity.

The length of the supporting frame is calculated to accommodate two or more cassettes with a size of 2000 × 2000 × 2500 mm, corresponding to its length, width and height.

Thus, interconnected cartridges with gas cylinders mounted on a supporting frame create a single power system with strength and spatial rigidity, capable of withstanding static and dynamic loads.

In addition, the inventive device has a simple and reliable design in comparison with the prototype device, eliminating the need for a semi-trailer equipped with appropriate means, in particular, a wheel module, braking means, a hitch with a tractor.

The disclosure of the essence of the utility model is complemented by some design features.

To perform the function of gas filling, the claimed device occupies the so-called working position on the supporting posts of the supporting frame. In this case, the support legs are connected with the end cross members of the supporting frame, i.e. for a stable position of the entire structure of the gas filling unit, the support posts support it at four angles.

The end cross members are made with protruding parts (protrusions) having a trough-shaped profile open to the side of the edge for constructive connection of the support posts with end cross members, if it is possible to bring the support posts to the working / transport position using a mechanical drive.

The mechanical drive is made in the form of four worm gears (in terms of the number of support posts), which ensure that the support posts are rotated in a vertical plane between the working vertical position and the transport vertical position. The housing of the respective worm gearbox can be mounted on the outside of each protruding portion of the end cross members.

The presence of L-shaped connecting elements, which are a continuation of the support struts and protruding into the open profile of the protrusions of the end cross members, determine the possibility of the working position of the support struts at an optimal distance (in the transverse direction), selected from the condition of placing a truck chassis between them. This condition corresponds to the need to transport a gas refueling unit with the possibility of entry / exit of the truck chassis to and from the indicated unit.

The connection of the worm gearbox passing through the protruding part of the output shaft cross member with the L-shaped element determines the rotation of the support posts around an axis that coincides with the axis of the output shaft, and at the same time, the location of the support posts in the transport vertical position, which are inverted (relative to the working position) and located along the cassette

Means for bringing racks into working or transport position does not complicate the proposed device due to the possibility of performing a traditional mechanical drive and the optimal number of connections.

The presence of intermediate cross members is necessary for the structural rigidity of the supporting frame.

The implementation of the support posts adjustable in height brings its advantages, namely: the convenience and reliability of using the utility model, manifested when it is necessary to place the gas filling unit on an uneven and / or level surface of the site.

In more detail, the transported gas filling unit is illustrated in the drawings. Figure 1 shows a General view of the device, figure 2 is a rear view of the device relative to the truck.

The inventive device contains, for example, three cassettes 1 with gas cylinders 2 mounted on a supporting frame with spars 3, edge cross members 4, located between them by an intermediate cross member 5 and supporting posts 6.

Each cassette 1 is made in the form of a metal structure, which is a box-shaped frame with parallel walls 7 having openings 8; the walls 7 are attached to the uprights and longitudinal beams relative to the direction of the side members 3; the frame contains transverse crossbars, side connections that can be made inclined (not shown in the drawings). Cases of gas cylinders 2 are placed in the holes 8 with support on their surface. The closest possible location of the openings 8 is explained by the need to perform a gas filling unit for its function: to ensure the maximum capacity of transported gas cylinders (subject to safety conditions during transportation and storage of gas cylinders).

Cassettes 1 are installed on the side members 3 and attached to them around the perimeter using a bolted connection (not shown in the drawing). Between themselves, the cassettes 1 are also connected from above using a bolted connection fastening the adjacent (upper) crossbeams of the frame.

The spar 3 in cross section consists of two channels facing the shelves in different directions and connected by plates from above and below (figure 2). Between the side members 3, guides 9 are arranged for sliding the rollers 10 along them, which can be equipped with the frame 11 of the truck 12 for the convenience of entering under the gas filling unit on the supporting posts 6, and leaving it.

For transportation of the gas refueling unit, the truck frame is equipped with means for fastening the carrier frame of the refueling unit (not shown in the drawings).

In figures 1, 2, the supporting posts 6 are depicted respectively in a transport vertical position and in a working vertical position; using a manual drive in the form of a worm gear 13 of the rack 6 rotate in a vertical plane between the working position with the support on the platform and the transport vertical position.

To connect the support posts 6 with the end cross members 4, the latter are made with protruding parts (protrusions) 14 having a trough-like profile open towards the edge of the cross member 4, and each support post 6 is provided with a corresponding L-shaped connecting element 15, which is its continuation, when this free end of each connecting element 15 is installed with the entry into the "own" ledge 14. The housing of the worm gear 13 is mounted on the outside of the protruding part 14 of the end cross members 4 with the possibility of control using the handle 16, while the output shaft (not shown) of the actuator 13 is located across the protrusion 14 and passes through the setting end of the connecting element 15.

When the support posts 6 are in the transport position, the connecting element 15 rests on the bottom of the trough-like profile of the protruding part 14, while the inverted support column 6 is as close as possible to the cassette 1, thereby ensuring the compactness of the device during transportation in compliance with the transport dimensions (figure 1).

In the working and transport positions, the support posts are fixed.

Each end cross member 4 in the middle part located between the side members 3 has a box section, which is the most durable.

The implementation of height-adjustable support racks 6 may be similar, for example, to the technical solution described in patent SU No. 1532382 "Support device of the semi-trailer" or other known solutions.

In this example, telescopic support posts 6 are used, each with a support foot 17; Racks 6 are selected from the catalog of purchased products under the number 5205-2700035-03 as a structure with the possibility of smooth adjustment in height, achieving alignment of the supporting frame in order to eliminate torsional-bending loads.

Support racks 6 are housing elements; the length of each rack 6 is regulated by a spindle (not shown in the drawing) located inside the rack. The helical gear drive is made, for example, in the form of a bevel gear controlled by a handle (not shown in the drawings).

The gas refueling transporting unit is equipped with shut-off and control valves (not shown in the drawing) and a control unit 18, designed to account for released gas and control technological parameters.

The control unit 18 is mounted on the rear end cross member 4 (relative to the position of the gas refueling unit on the truck).

The device operates as follows.

In the transport position with the support legs 6 retracted, the gas refueling unit is delivered to the consumer’s platform by truck 12. The support legs 6 from the transport vertical position by means of a mechanical drive 13 are set to the working position based on the platform. If necessary, the support posts 6 are height-adjustable to achieve a stable horizontal position of the carrier frame with cartridges 1. After installing the gas refueling unit on the site, the truck 12 moves out from under it.

Further preparation of the gas filling unit for operation is carried out by adjusting the shut-off and control valves together with the control unit 21.

To remove a unit with empty gas cylinders from the consumer’s platform, the truck in the position that ensures the rollers 10 of the frame 11 of the car 12 slide along the guides 9, drives under the gas filling unit, after which the support posts 6 are rotated to the transport position. The filling unit is ready for transport again.

The transported gas filling unit expands the range of known similar means and makes it possible to use it as a replaceable unit in the well-known “swap body” system (swap body); This unit is designed for delivery to the consumer by a MAZ-6312B5 truck with a frame structure adapted to the supporting frame of the unit itself, and can be used to serve compressed gas consumers in vehicles with gas equipment, at mini-gas stations as a fuel power unit , for small boiler houses for temporary meals.
