Description

The utility model relates to a device for protecting the automatic combi steamer from vibration and shock during transportation and during operation in a box body.

Known combi steamer (http://www.parokonvektomat.ru/techno/tehnicheskoeopisanie) [1], designed for heat treatment of food, containing a housing, a camera, a control unit. As a result of experimental studies, it was found that the main disadvantage during the operation of this heat apparatus during its transportation and during operation in a van body while moving the base chassis of a field technical device on its own over rough terrain is a decrease in the duration of working capacity.

The prototype of the technical solution is a field kitchen (RF Patent 123502, Field kitchen, application No. 2011132489/03, prior 02.08.2011, published on 27.12.2012. Bull. 36) [2], intended for cooking in the field, consisting of an established on the car trailer of the brew unit. The disadvantage of the prototype is the inability to provide an increase in the performance of the heat device under conditions of single and repeated mechanical shocks when moving the base chassis of the field technical means over rough terrain on its own.

The technical task of the utility model is to reduce vibration and shock loads on the automation of the combi steamer during operation inside the van body.

The technical problem is solved due to the fact that the device for protecting the automatic equipment of the combi steamer from vibration and shock effects during its transportation and during operation in the van body contains a ZhTA-25 shock absorber for attachment to the niche of the van body, which is rigidly fixed on a fixed platform , on which the legs of the combi steamer are attached, while the platform is made of high-strength alloys based on aluminum (aluminum alloy) with the addition of copper, magnesium and manganese, on the end side of which a pillow is fixed, made of rubber.

The technical solution is illustrated in FIG. 1, which shows a device for protecting the automation of the combi steamer from vibration and shock effects during transportation and during operation in a box body, where pos. 1 - shock absorber; pos. 2 - combi steamer; pos. 3 - leg; pos. 4 - thrust bearing; pos. 5 - niche; pos. 6 - platform; pos. 7 - pillow; pos. 8 - floor; pos. 9 - retainer; pos. 10 - bolt; pos. 11 - holder.

The essence of the technical solution is that the combi steamer is rigidly fixed on a special mounting platform, which is fixed flush on the cable shock absorbers in the floor recess of the van body (Fig. 1).

The platform on cable shock absorbers consists of shock absorber 1 (optionally, four, brand ZhTA-25 ("rigid" cable shock absorber of vertical stress for a nominal weight of 25 kg) (Cable shock absorbers (vibration isolators) with a nanocomposite polymer-metal cable [Electronic resource] www.rusnanonet. ru) [3] with an additional spring element, which reduces vibration and shock loads in all directions (dynamic characteristics of Fig. 2, which shows pos. 12 - vertical compression; pos. 13 - tension at an angle of 45 °; pos. 14 - compression at an angle of 45 °; pos. 15 - horizontal compression; pos. 16 - vertical stretching). The shock absorber 1 is fixedly fixed on one side of the holder 11 (as an option, several, in the shape of a pin with a threaded connection at the top point), in a niche 5 , to the floor 8 of the box body, and the second side through a threaded hole in the platform 6 (as an option, from high-strength alloys, based on aluminum (aluminum alloy) with the addition of copper, mag and manganese), rigidly by a bolt 10 is connected through with a thrust bearing 4, fixed at the end of the leg 3 of the combi steamer 2. On the end wall of the platform 6, the pillow 7 is rigidly fixed (as an option, made of rubber). On the end wall of the niche 5, a retainer 9 is fixedly fixed (as an option, frost-resistant rubber 50 mm thick).

Operation of the platform on cable shock absorbers is as follows. The combi steamer 2 is fixed, through the leg 3 and the thrust bearing 4, with a bolt 10 through the platform 6 to the shock absorber 1. When the base chassis moves, not shown in the figure, sharp oscillatory movements occur over rough terrain, the effect of which on the automation of the combi steamer 2 is reduced due to the operational properties shock absorber 1, providing stability in conditions of prolonged static and dynamic loading. The presence on the end wall of the platform 6 of a rigidly fixed cushion 7 and on the end wall of the niche 5 of the retainer 9 provides additional protection of the automation of the combi-steamer 2 from vibration and shock effects.

Experimental studies at the Proektintertekhnika LLC plant to test the performance of the proposed device inside the van body during the period of movement of the base chassis over rough terrain made it possible to establish that the vibration and shock effects on the automation of the combi steamer are reduced by 1.4-1.5 times, and the duration its exploitation increases 1.3-1.42 times.

Thus, the proposed device has a novelty and significant differences from the prototype, provides a decrease in vibration and shock loads on the automation of the combi steamer during its operation inside the van body. The technical solution can be used in the technological block of field technical means for cooking and in galleys.
