Description

The invention relates to mechanical engineering, namely to heating by closed combustion, aggregates and units of construction machines (earth moving machines, road, hoisting and transporting machines and equipment) operating in the field.

The experience of operating machines in low negative temperatures, as well as the analysis of statistical data shows that about 70% of all failures occur in the components and parts of the hydraulic drive [Merdanov Sh.M. et al. Research and development of a thermal preparation system for the hydraulic drive of building and road machines // "Construction and road machines", 2013, No. 1], which is explained by an increase in the viscosity of the working fluid during parking. The hydraulic drive of machines operating in the field is ensured by heating the working fluid, and therefore, with a decrease in viscosity.

It is known [RF Patent No. 54499 IPC: A47J 37/06, F24C 1/16, publ. 07/10/2006] a device related to devices for preparing a variety of dishes on charcoal, with the functions of self-blowing, ventilation and temperature control. The brazier consists of a frying compartment and a lid with heat-resistant glass inserted and a box-shaped ash pan. The exhaust chamber is adjacent to one side. The device of the type grate allows the coals to burn evenly even with the lid open. The absence of smoke and open fire expands the possibilities of using this grill in closed and partially closed rooms. The model is suitable for a cafe and a country house (cottage).

Known invention Mangal [RF Patent No. 2402970, IPC: A47J 37/07, A47J 37/04, publ. 11/10/2010], which relates to devices for cooking on an open fire. The brazier contains a bottom 1, support elements made in the form of legs 2, and walls 3. At least two walls, as a rule, are mutually opposite longer walls - side walls 4 consist of at least three parts 5 connected to each other with the possibility of compensating for their thermal expansion.

A device is known for warming up a hydraulic tank and an SDM engine [RF Patent No. 2560767, IPC F02N 19/04 (2010.01), publ. 08/20/2015], which has a housing in the lower part (bottom) of which there are two or more channels. In the channels are transporting rods, one end of which is made with a place for a tablet, designed to light a fire, and the other end contains a handle for moving the rod along the channel. On top of the case is equipped with a fully removable cover with perforated heights with grooves for fastening the guide pipes. The guide pipes can be of different shapes and have the ability to be mounted on each other (due to different diameters, in the upper and lower parts of the guide pipe), for a more local, directed heating. On the front of the case, at the level with the handles for transporting the rods, there is a conveying arc. The device can be mounted on a means of transportation, such as skiing.

Common disadvantages of the device is the unsuitability of use for heating construction equipment when placed under construction equipment. It is necessary to remove the legs of the device for placement under the equipment, this reduces stability. There is no possibility of regulating air flow (when used under construction equipment). The cover is a heat-reflecting screen (direction of heat inside the device), low heat generation (prevention of open burning of fuel), in the absence of a cover, the formation of open burning is possible, which leads to failure of construction equipment.

The task to which the claimed technical solution is directed is to accelerate the process of the output of the device for heating the tank and the SDM engine to the working temperature of heating, depending on the weather conditions (temperature, wind) and work requirements associated with the need to change the rate of combustion of fuel ( warming), as well as the energy efficiency of its use. Reliable and comfortable device control is required.

The technical result of the proposed design of the device for regulating the heating intensity of construction vehicles is the regulated air supply to the housing of the device for heating the hydraulic tank and the SDM engine by changing the characteristics (shape, size, quantity) of the matching openings of the fixed and movable walls (the holes of the walls can be of various shapes and correspondingly formed when the holes from the two walls coincide, the holes can have a different shape). The characteristics of the holes vary depending on the relative position of the holes of the movable and fixed walls.

The specified technical result is achieved in that the device for regulating the intensity of heating of construction equipment consists of fixed and movable walls, each of which has holes of a given shape. When the movable wall is displaced relative to the fixed wall, the holes coincide and through holes are formed in the areas where the openings of the fixed and movable walls join. Holes of a new shape are formed. It is possible to adjust the amount of air supplied to the body of the device for heating the hydraulic tank and the SDM engine by changing the size and shape of the holes. There is a hook with a telescopic handle for easy adjustment.

The device consists of at least two fixed walls 1 and at least two movable walls 2, each of which has through holes 3, 4, respectively, located in a certain order. The fixed wall 1 and the movable wall 2 are mounted on a side opening cut out for them in the side walls. When considering the example of a device for heating the tank and the SDM engine [RF Patent No. 2560767, IPC F02N 19/04 (2010.01)], the side walls will be the walls parallel to the guide rods. Each pair of movable walls 2 and fixed walls 1 are fixed with two guides 5 located along the entire length of the lower and upper edges, fixed and movable walls 1, 2, which have an inner track 6 for fixed walls 1 and an outer track 7 for movable walls 2 In Fig. 2. at the opposite end from the front of the rails 5 there are latches 10 that fix the fixed and movable walls 1, 2 in the initial maximum retracted position (not a single hole 3 of the fixed wall 1 coincides with the holes 4 the wall 2). At the end of the movable walls 2, located closer to the front of the device for heating the hydraulic tank and the SDM engine, there is a fixing hole 8 for the ring 9.

To install a device for warming up the hydraulic tank and the SDM engine [RF Patent No. 2560767, IPC F02N 19/04 (2010.01)], it is necessary to cut the walls from the sides so that subsequently the fixed walls 1 can overlap the cut hole along the perimeter (shown in FIG. one). Guides 5 are mounted along the lower and upper part of the side hole.

The acceleration of the process of the output of the device for heating the hydraulic tank and the SDM engine to operating temperature, as well as increasing the intensity of combustion or energy-efficient combustion of fuel in the device for heating the hydraulic tank and the SDM engine, occurs by regulating the air supply to the device body by matching holes in the movable and fixed wall. Depending on different weather conditions, in different regions of operation (strong wind, temperature, discharged air) of the device and on the tasks set (quick warm-up or energy-saving), various options for the shape, size and number of openings of fixed and moving walls 1, 2 can be used.

In FIG. 1 shows a device for controlling the intensity of heating of construction vehicles, installed for example on a device for heating the hydraulic tank and the SDM engine.

In FIG. 2 - a fixed wall 1 fixed by the guides 5, the letter A indicates the attachment points (for example, a welded joint) of the guides 5 to the device for heating the hydraulic tank and the SDM engine (side and front views).

In FIG. 3 - the position of the fixed wall 1 and the movable wall 2 relative to each other. The coincidence of the holes of the fixed and movable walls 1, 2 are highlighted in black (a - there are no matches of the holes, b is the partial coincidence of the holes, c is the maximum coincidence of the area of the holes). In FIG. 3 in the bottom row of holes 3, 4, dotted lines indicate holes 3 of the fixed wall 1.

In FIG. 4 - fixing the ring in the hole.

In FIG. 5 shows the hook in three forms, the dashed line shows the retracted position of the telescopic handle.

In FIG. 6 shows the adjustment of the movable wall with respect to the fixed wall using a hook (top view). The white arrow - the extension of the movable wall relative to the stationary one - an increase in matching holes to the maximum area of matching holes. The black arrow - pushing the movable wall 2, along the outer track 7, the guides 5 relative to the stationary 1 - decrease matching holes until they are completely closed.

The device consists of a fixed wall 1 and a movable wall 2, each of which has its own holes 3, 4. The fixed wall 1 and the movable wall 2 are attached to the wall of the device to be upgraded from at least two sides using guides 5 (guides 5 are located below and above fixed, movable walls 1, 2), the guides 5 have inner tracks 6 for fixed walls 1 and external tracks 7 for movable walls 2 (Fig. 2). The fixed and movable walls 1, 2 have the same overall dimensions, so they can be interchanged. A movable wall 2 is a wall that is located on the outer track 7 of the guides 5. The guides 5 are located so that the lower edge and the upper edge of the movable wall 2 are in the inner tracks 6 of the guides 5, and the lower and upper edge of the fixed wall 1 is on the outer tracks 7 guides 5. At the opposite end from the front, on the guides 5 there are latches 10 for fixed and movable walls 1, 2. At the end of the fixed walls 1 and movable walls 2, a fixing hole 9 is located closer to the front part I am the ring 8. A ring 8 is inserted into the hole 9, into the movable walls 2 (located on the outer track 7) (Fig. 4). There is a hook 11, which has the ability to catch on the ring 8, inserted into the hole 9 of the movable wall 2 to adjust the position of the movable wall 2 relative to the fixed wall 1. The hook 11 at its end has a shape for easier hooking of the hook 11 and the ring 8. Hook 11 has a telescopic handle for ease of use (Fig. 5 dashed lines show the handle in the retracted position). The hook 11 has the ability to both pull and push the ring 8 of the movable wall 2 by engagement with the ring 8. Along with this, the matching holes 3, 4 of the fixed and movable walls 1, 2 are adjusted, or the holes 3, 4 coincide and the through holes are formed in the places of combining the holes 3, 4 of the fixed and movable wall 1, 2, or the overlapping of the holes 3, 4. The hook 11 for more convenient use for a person has a telescopic handle that can be extended to a certain length (for convenience).

The use of a device for regulating the intensity of heating of construction machines allows you to adjust the amount of air in the device for heating the tank and the SDM engine [RF Patent No. 2560767, IPC F02N 19/04 (2010.01)]. Regulation of the ratio of air and fuel allows you to speed up or slow down the heating process, depending on weather conditions, air temperature, humidity, timing of the heating time. To modernize the device for warming up the hydraulic tank and the SDM engine, it is necessary to cut out the side holes in the side walls so that subsequently the fixed walls 2 have the ability to overlap the cut out side hole around the perimeter. Guides 5 are mounted along the lower and upper part of the side hole.

The device operates as follows, before loading the device for heating the tank and the SDM engine [RF Patent No. 2560767, IPC F02N 19/04 (2010.01)] with fuel (coal, peat, dry wood, bark, ignition fluid), a selection is made (by quantity, the shape, size and frequency of the holes — some of the examples of holes are shown in Fig. 3) fixed walls 1 and movable walls 2 and their installation. The number, shape, size and frequency of the holes are selected depending on various conditions (for example, weather conditions, air temperature, humidity, heating time limit), which will be fixed walls 1 and moving walls 2, in accordance with this fixed walls 1 are installed in the inner tracks 6 of the guides 5, and the movable walls 2 are installed on the outer tracks 7. A ring 8 is inserted into the hole 9 of the movable walls 2. The fixed and movable walls 1, 2 are retracted to the original maximum inute position (Fig. 3 - there is no coincidence of the holes) until it stops in the latch 10.

After the complete preparation of the upgraded device for heating the hydraulic tank and the SDM engine and transporting it and installing it on the heating site, it is possible to hook the ring 8 with the hook 11 and to displace (pull / push) the movable wall 2 relative to the fixed wall 1, at the same time coincidence or overlapping of holes 3, 4.
