Description

The inventive utility model relates to devices for placing equipment on vehicles, mainly for placing batteries under a railroad car, and can be used in the construction of vehicles containing batteries, for example, in locomotives.

Widely known various designs of devices for placing batteries on vehicles.

So, it is known a device for placing batteries (Zorokhovich A.E., Libman A.Z. Electrical and radio equipment of passenger cars. M .: Transport., 1977, p. 102), located in the middle of the frame of the car in the fuel tank area, containing battery compartments with covers placed at a small height above the level of the rail head (300 mm in the open position). The lid is installed so that it opens downward, and the hinges are located on the lower bottom of the battery compartment, while the locks are located on the upper level of the battery compartment.

This device has several disadvantages due to the following reasons.

This is a known device with batteries located in it, due to the fact that it is located in the middle of the frame above the fuel tank, it works under difficult conditions. During operation, the device is subject to significant dynamic forces resulting from vibration of the power plant (diesel generator), which can lead to damage to both the walls and all components of the device, and the batteries (failure). In other words, the known device is fragile in design as a whole, as well as the low strength of its elements. So, the cover locks located in the upper part of the battery compartment, made in the form of an arcuate spring. They are unreliable in operation, since arcuate springs quickly lose their elastic properties during operation, and this leads to a lack of tension between the parts to be connected, and consequently to arbitrary lock release, creating an emergency situation when the car moves, as well as creating a threat to maintenance personnel.

Thus, the disadvantages of this known device are the low operational reliability and low strength of the device, leading to its rapid destructibility due to the fragility of all components of the structure. The disadvantage of this device is the inconvenience in the maintenance of the batteries, as structurally not provided easy access to the battery compartment. This known design does not solve the problems associated with the ingress of dust, moisture, dirt from the wheels into the internal volume of the device, which causes corrosion of the metal parts of the battery boxes and reduces the reliability of the batteries, increases the risk of explosion.

Known devices for placing batteries, the designs of which solve the problem of increasing reliability and ease of maintenance. For example, it is known a device for placing batteries on vehicles, mainly in locomotives (Author's certificate. SU No. 1791 206, class B60R 16/04, publ. 30.01.1993), containing battery compartments, placed under the level of the upper deck of the vehicle bodywork, each of which it is formed by the side, lower and upper walls and a hinged lid with locks having rotary handles and an element for keeping the lid open. The reliability of the device is enhanced by attaching the cover in the upper part of the battery compartment and its tight fit under the influence of its own weight to the walls of the compartment around the perimeter, as well as by placing the lock in the lower part of the battery compartment.

Ease of maintenance of the device is ensured by fixing the cover in the open position above the head of the person performing the maintenance. This known device has several disadvantages. The design of the device is not strong enough due to the presence of many interconnected parts that collapse under the action of constant vibrations when the car moves. The design does not provide sufficient amenities for the maintenance of batteries, since they are permanently placed in compartments. When servicing such devices, explosive situations are likely.

Known designs of devices for placing batteries in which increased operational reliability and ease of maintenance. For example, it is known a device for installing batteries on a vehicle, mainly a car, (Aut. St. SU No. 1388336, class B60R 16/04, publ. 04/15/1988) containing guides for rollers placed on a fixed base, and a retractable frame equipped with rollers. The device is equipped with a pallet mounted on a sliding frame, and made with the upper side edge bent outward with the possibility of overlapping around the perimeter of the sliding frame, and the pallet is made with at least two drain holes in the bottom, equipped with rods that are brought out. The pallet and rollers are made of dielectric material. The lower and upper base, walls and hinged lid are made of wood.

The batteries collected in the battery are installed in the tray of the retractable carriage.

For charging and technical inspection of the battery, the sliding frame along the rails is rolled out onto the hinged lid of the car box until it contacts the stop. The batteries are inspected or replaced, and then the sliding frame along the rails is put in place inside the car box for operation.

During the movement of the car or in the case of boiling, the electrolyte overflows over the edge of the battery jars and flows to the bottom of the pallet, from where it flows out through the drain holes through the tubes out under the car.

This device has improved operational reliability by eliminating the ingress of electrolyte on metal and wooden parts of the frame and car box. However, the known device has several significant disadvantages.

The presence of wooden parts - the entire car box and its lid - significantly increases the fire and explosion hazard of the device. This device provides great ease of maintenance due to the presence of a retractable frame, but operational reliability is insufficient: the battery is exposed to dust, dirt, atmospheric precipitation. In addition, when using batteries with a large number of elements in vehicles, a large degree of rolling out the frame from the box is required, and a large isolation of the battery from metal structures is also required.

Known battery box locomotive (Patent for utility model RU No. 157084, class B60R 16/04, publ. 11/20/2015), comprising a housing, a retractable trolley, movably mounted in the housing and a tray for batteries located on a retractable trolley. The pull-out trolley is equipped with a lock for the fully extended position of the trolley. The latch is made in the form of a spring-loaded pin and mounted on the rear of the frame of the trolley, and the body is equipped with a strip designed to slide the pin head when moving the trolley, while in the strip there is a hole for recessing the pin head.

Information:

1) - pin - (German, stier - motionless). A special cylindrical rod with a tapered end, used to center and guide the connected detachable parts of the structures. ("The Big Explanatory Dictionary of the Russian Language", edited by S. A. Kuznetsov, St. Petersburg. "Norint", 2000, p. 1507)

2) - strip - a thin long piece of any material (metal, paper, fabric). ((“The Big Explanatory Dictionary of the Russian Language”, edited by S. A. Kuznetsov, St. Petersburg. “Norint”, 2000, p. 906)

The disadvantages of this known battery box due to the following. Obviously, the design of this box can allow the extension of the trolley with batteries (total weight of about 500 kg) not more than ½ the length of the box, eliminating the risk of the battery falling with the trolley down. If you try to push the trolley fully, the guides that hold the trolley will bend or break badly and the trolley with batteries will fall down.

The latch for the fully extended position of the trolley is not reliable, since the pin may slide off the strip, and the locking may not be possible. Thus, this known design of the battery box is unreliable during operation, inconvenient for maintenance, since it does not provide sufficient access to the batteries.

Known battery boxes, the design of which increases its operational qualities: facilitates access to batteries, provides ease of maintenance. So the car’s battery box is known (ed. St. S4 No. 680.930, class B60P 1/52, publ. 08.25.1979), containing a bottom with rollers, a lid pivotally attached to the bottom, which carries a locking device for fixing it in a closed and open positions, and hinged brackets connected coaxially by hinges to the end part of the cover.

The disadvantages of this device are as follows. The design of the device is complicated by many interconnected nodes and parts, and this leads to a decrease in reliability during operation.

The closest in technical essence to the claimed object is the design of the car battery module according to the patent of the Russian Federation No. 2104182, B60R 16/04, publ. 02/10/1998 (Prototype). This module contains a housing and a withdrawable trolley, movably connected to each other by installing rollers on the trolley and guides located on the housing, a front hinged lid with guides fixed to it, the trolley made in the form of a frame with a battery installed in it and equipped with insulating elements, the module is equipped with a battery mount fixture. Additionally, the movable guide bodies and covers are inserted into the module with the possibility of their rotation relative to the fixed respective guides and installation in the horizontal plane, the guide bodies are additionally equipped with fastening and fixing units made in the form of a brace, a finger and a groove on the guides and a support element with an inclined and vertical platforms - on the case, the fixture for fixing the trolley in the case is formed by a movable guide of the case and elements of the fastening and fixing unit of the guides - about Aulnay groove finger and ramp support member. The insulating elements are made in the form of plates of dielectric material and mounted on the inner lower and side surfaces of the frame on the pins.

This design of the known device allows folding and unfolding the movable rails in a horizontal plane so that folding rails are formed with a length that ensures the cart is fully rolled out of the housing to a sufficient distance for convenient maintenance.

In this design, the guides do not have rigidity, so smoothness and accuracy of movement are not guaranteed.

Thus, known from the patent of the Russian Federation No. 2104182, the movable battery module has a complex structure, including many interacting with each other nodes and parts, while the design does not have sufficient rigidity, strength and reliability. In this known design, the time for servicing the battery packs is significantly increased, since additional time is required for folding and folding the guides.

The task to which the claimed technical solution is directed is to create a highly reliable battery box for placing batteries under a railroad car, the design of which differs from the known solutions in increased strength and rigidity, compactness and long trouble-free operation resource, convenient conditions for quick service.

These qualities are ensured due to the fact that the claimed design solves the problem of creating strong blocks of the device, which ensured the creation of a rigid construction of the displacement block, due to which sliding contact is ensured when working with heavy loads, the problem of tight closure of the box is structurally solved.

When creating the design of the claimed device for solving the tasks, the developed technical solution for operation in adverse conditions should have:

- optimal compactness, manufacturability and simplicity of design with severe restrictions on weight, dimensions and technical parameters,

- stability of technical data,

- increased strength and endurance of both the main blocks and their elements,

- increased resistance to mechanical shock,

- must be resistant to high humidity.

The claimed technical solution can be recognized as meeting the requirements of novelty, since no analogue has been found that is characterized by features identical to all the essential features of the proposed object of protection.

The claimed technical solution meets the requirement of industrial applicability, since it is manufactured and used (see the attached advertisement on one sheet).

A battery box for accommodating batteries under a railroad car is proposed, comprising a box-shaped housing with a movable carriage housed therein with a cassette holder for the battery, a carriage moving unit including paired first stationary guides mounted on the inside of each side wall of the housing, paired middle movable guides, paired second fixed guides and elements for connecting the guides, block for fixing the carriage outside and inside the housing, insulating elements tion of the battery from the housing, the front cover and the block circuit box.

The block 6 for moving the carriage 3 includes paired first fixed guides 11 (Fig. 2, 6), mounted on the inner side of each side wall of the housing 2, paired middle movable guides 12 (Fig. 3, 4, 6, 7), paired second non-movable guides (pos. 13 of Fig.) and connecting elements of the guides. The connecting elements of the guides are made in the form of two pairs of linear ball bearings 14 (in Fig. 6, 7). each of the middle movable guides is made in the form of an I-beam 12 (Fig. 6, 7) with radial grooves 16 located on the inner faces of its shelves (Fig. 7). The second fixed guides 13 are fixed on the outer sides of the carriage 3 (Fig. 3, 4). At the ends of the first and second fixed guides (pos. 11 and 13 in Fig. 6, 7), longitudinal radial grooves (17, Fig. 7) are made, on top of which on each free side of the fixed guide there is a linear ball bearing 14 (Fig. 7) . Each fixed guide along with a linear ball bearing is telescopically connected to the corresponding side of the middle movable guide, made in the form of an I-beam 12 (Fig. 6, 7). With such a connection of the guides, the linear ball bearings are mounted for movement in the longitudinal channels 18 (Fig. 6, 7) formed by the longitudinal radial grooves 16 of the I-beams 12 and the same grooves of the adjacent stationary guides 11 and 13.

The block 7 (Fig. 5, 8) for fixing the carriage outside and inside the housing 2 has a protective frame 19 installed on the rear wall of the carriage 3 (Fig. 5, 8), in the upper and lower bases of which are made two holes placed opposite one another, in which with the possibility of free movement, a latch (Fig. 7) is installed in the form of a spring-loaded cylinder 20 (Fig. 8). The working part of the locking cylinder 20 is placed under the frame 19 and is rigidly fastened to the lever - the strap 21 (Fig. 5, 8), on the other end of which an anti-jamming element 22 is installed (Fig. 8), for example, in the form of an axial cylinder. Block 7 is also equipped with limiters of the external and internal fixation of the carriage, each limiter made in the form of a U-shaped springboard 25 and mounted obliquely at the beginning and end of the brackets 26 located inside the housing 2 at the level of the said protective frame 19 (Fig. 5).

The battery isolation elements from the housing are made in the form of fiberglass plates 8 (Fig. 2), (for example, grade STEF-1.V.S-2, GOST 12652-74) monolithically bonded to the supporting pads 37 of the battery holder 4 of the battery 5. The front cover 9 is fixedly attached to the front wall of the movable carriage 3 and is provided with a protrusion 23 (Fig. 9) fixed around the perimeter of its inner side, over which a seal 24 (Fig. 9) is made, made of ethylene - propylene copolymer (rubber), for example, grades 401 0102 Gista Selection (EPDM), (seal 9.8 × 27 KLB1- 3).

Block 10 closure of the box is made in the form of a system of four cylinder mortise locks 24 (see Fig. 10), located on the front cover, and on its outer side each lock contains a trihedral larva 25 for installing the key, and from the inside of the cover 9 on one fixed axles 27 with protruding hook 28 and associated movable segment cam 29 with arcuate-wedge tightening element 30, placed with the possibility of gradual approach under the locking angle 31 on the housing 2. with this lock mechanism dense, with gain compression pull the sealing element on the perimeter and locks the lid to the opening of the housing. This ensures reliable, tight and durable closing of the lid by a system of four original locks, which excludes accidental opening of the box. On the outside, the cover 9 has two loopback handles 32 for rolling out and rolling the carriage 3.

Ventilation air enters the housing 2 through special openings in the cover, and exits through the holes in the rear wall of the housing 2.

The inventive battery box 1 for placing batteries under a railway carriage operates as follows.

The batteries collected in the battery 33 are installed in a cassette holder 4, fastened with ties and installed in an extended movable carriage 3. the battery 33 is isolated from the carriage 3 due to the fact that the inner sides of the support pads 37, on which the battery 33 is located, are equipped with fiberglass insulating plates 8, monolithically fastened with the supporting platforms 37 of the cassette holder 4.

The weight of the batteries is about 400 kg. This increased load on the movable carriage 3 allows the construction of a double-tee beam to reinforce the structure and giving it additional rigidity without bending the guides, since this increased load on the movable carriage 3 allows the proposed design of the movable guides 12 to be perceived without bending as guiding beams in the form of I-beams reinforcing the strength of the structure and giving it additional rigidity. Due to the rigid structure with minimal deflection, the appearance of high static strength (a new property) is provided, which allows to increase the reliability of the device, simplify the design, increase the speed and safety of service. The loaded carriage 3 is smoothly moved inside the housing 2 and is fixed in this design using the block 7 for fixing the carriage inside the housing 2. Moving the carriage 3 is carried out by the block 6 for moving the carriage, including the first fixed guides 11 mounted on the housing 2, the second fixed guides 13, mounted on the carriage 3 and the movable guides 12 in the form of I-beams, as well as the elements of the connection of all the guides in the form of linear ball bearings. The proposed design of the block for moving the carriage 3 due to the rigid structure of the telescopically assembled guides with linear ball bearings allows you to save smoothness, ease and accuracy of movement of a large load throughout the course.

In this case, in a retracted position inside the housing, the carriage 3 with the loaded battery pack is securely suspended on stationary and movable rails with the formation of a gap around the carriage 3, which completely eliminates the electrical closure of the battery on the housing in operation. This ensures the explosion safety of the device.

The carriage 3 is extended by the carriage moving unit easily, accurately and quickly to a distance sufficient for convenient maintenance. The proposed design of the device provides convenient and safe conditions for maintenance in a short time.

Thus, the claimed technical solution is an original battery box for placing batteries under a railway carriage, which differs from the known solutions in high reliability, durability, endurance and explosion safety when operating in adverse conditions (vibration, temperature, pressure, dust, pollution, rain snow).

The inventive device is structurally solved the problem of creating a simple, but reliable and explosion-proof battery box for placing batteries under a railroad car. Moreover, in the claimed design of the device, the following technical and economic results are achieved:

- optimal compactness, manufacturability and simple design with severe restrictions on weight, dimensions and technical parameters;

- increased strength and endurance of both the main blocks and the means connecting them;

- increased explosion safety when exposed to vibration, high and low temperature, high humidity;

- Convenient and safe conditions for quick maintenance.
