Description

Technical field

The invention relates to the field of loading and unloading operations and can be used to heat frozen cargo in a car at the places of rolling stock unloading.

State of the art

From the prior art, a device is known for heating frozen cargo in cars, containing a base, a rail track located on the base, a thermal chamber installed on the base and covering with its internal cavity a car with frozen cargo, upper sources of thermal energy installed on the upper, inner surface of the thermal chambers above the frozen cargo in the car, side sources of heat energy installed outside the overall dimensions of the car with frozen cargo, on the right and left sides, along the longitudinal axis of the car with frozen cargo and lower sources of heat energy installed outside the overall dimensions of the car with frozen cargo, on the right and left sides, along the longitudinal axis and obliquely to the outer surface of the bottom of the wagon with frozen cargo, characterized in that the upper, side and lower sources of thermal energy are made in the form of flat electric heaters (RU 137022, U1, B65G 69/20, publication date 27.01.2014).

The disadvantage of this device is the lack of mobility, as it is in a stationary state, which leads to additional operations for the delivery of rolling stock to the places of heating of frozen cargo.

A device for heating frozen cargo in a wagon is known. In a device for heating frozen cargo in a car, containing a base and an alternating voltage source with a converter, a working chamber is introduced, in the upper part of which vertical perforated panels, upper and lower rotating metal blades and upper rows of heating elements with microwave generators are installed on the sides and ends air-cooled, connected to a microwave path with irradiating waveguides and outputs in the form of slot antennas. Air-cooled microwave generators are made on the lower rows of heating elements. The car is equipped with non-contact temperature gauges for the outer surface of the car and frozen cargo, connected to the automatic control unit. The invention improves energy efficiency, reduces the duration of heating of frozen cargo in the car, improves safety (RU 2571678, C1, B65G 69/20, publication date 12/20/2015).

The disadvantage of this device is the lack of mobility, the complexity of the design, which leads to additional operations for the delivery of the rolling stock to the places of heating of frozen cargo and an increase in the cost of unloading the rolling stock with frozen cargo.

As the closest analogue, a device was adopted for heating frozen cargo in a car, consisting of side walls of the floor and heating elements, additionally introduced heat-insulating (penofol, cork, pelopropylene, glass wool or the like) and shielding (foil or fine mesh) materials that are different behind the other are fixed on the sides and floor of the car, and heating elements in the form of an electric heating cable are fixed to the shielding material (RU 2395444, C1, B65G 69/20, publication date 27.07.2010).

The disadvantage of the closest analogue is the lack of mobility, the high cost of equipment, powered by stationary power sources.

The technical problem of the claimed invention is to overcome the technical disadvantages inherent in analogues, which leads to the need to create a mobile overhead defroster for cars with frozen inert cargo.

Disclosure of the essence of the invention

The technical result of the claimed invention is the provision of mobility, the possibility of application at any railway stations where unloading of frozen inert cargo is required, as the use of an overhead defroster for cars with frozen inert cargo.

The technical result of the claimed invention is achieved due to the fact that the mobile invoice defroster for wagons with frozen inert cargo, consisting of a metal frame made of a square steel pipe, to the corners of which metal sling eyes made of a rod are welded, is characterized in that the device is configured to its installation on the wagon by a light-duty crane, the structure contains two transverse and two longitudinal beams made of similar materials of the main frame, with the formation of a seat for mounting a diesel-fueled air heater with a power of at least 134 kW, to which a flexible hose is connected for blowing hot air, the device contains a tarpaulin fire-resistant awning, larger than the dimensions of the car body by 1 meter and with a density of at least 800 g/m ² hot air, in the fire-resistant tarpaulin there is a technological hole for a flexible hose, on the opposite side of which an iris valve with a diameter of at least 200 mm is installed to relieve excess pressure from under the fire-resistant tarpaulin.

Brief description of the drawings

The claimed invention is illustrated by the drawing, which shows the following:

Fig. 1 is a plan view of a mobile defroster for wagons with frozen inert goods, FIG. 2 - side view.

Positions in the drawings indicate the following elements:

1 - metal frame,

2 - air heater,

3 - flexible hose for hot air supply,

4 - sling eyes,

5 - tarpaulin fire-resistant awning,

6 - eyelets,

7 - iris valve.

Implementation of the invention

A mobile consignment note defroster for wagons with frozen inert cargo is used to warm up frozen cargo in a wagon at railway stations where rolling stock is unloaded and not equipped with vibro-loosening equipment or greenhouses for hangar-type wagons.

The mobile consignment note defroster for wagons with frozen inert cargo works as follows:

on the gondola car with frozen inert cargo, a mobile invoice defroster for cars with frozen inert cargo is installed, consisting of a metal frame 1, to the corners of which metal slinging eyes 4 are welded. To reinforce the structure, two transverse and two longitudinal beams are made, which forms a seat for the air heater 2 , running on diesel fuel and having a power of at least 134 kW, to which a flexible hose 3 is connected for blowing hot air.

In order to save the heat of the supplied hot air for defrosting inert cargo in the car, a fire-resistant tarpaulin awning 5 is used, which is attached to the car frame through the eyelets 6 installed on the fire-resistant tarpaulin 5.

On the opposite side of the connected flexible hose 4, an iris valve 7 is installed to relieve excess pressure from under the fire-resistant tarpaulin.

Claims (1)

A mobile invoice defroster for wagons with frozen inert cargo, consisting of a metal frame made of a steel square tube, to the corners of which metal slinging lugs made of a bar are welded, characterized in that it is made with the possibility of its installation on a wagon by a low-capacity crane, the design contains two transverse and two longitudinal beams made of similar materials of the main frame with the formation of a seat for mounting a diesel-fueled air heater with a power of at least 134 kW, to which a flexible hose is connected for inflating hot air, the device contains a tarpaulin fire-resistant awning, exceeding the dimensions of the car body by 1 meter and with a density of at least 800 g / m ² , which is attached to the frame of the car with the help of a grommet made on a tarpaulin fire-resistant awning, a technological hole is made to supply hot air in a fire-resistant tarpaulin awning not under a flexible hose, on the opposite side of which an iris valve with a diameter of at least 200 mm is installed to relieve excess pressure from under a fire-resistant tarpaulin awning.
