Description

The utility model relates to the field of transport engineering and can be used in the design of a battery box for a diesel locomotive.

From the description of the patent US 6938553 B2, IPC B60D 11/00, publ. 09/06/2005, there is a known design of a battery box for a railway vehicle, including a housing, a pull-out trolley movably mounted in the housing, a battery tray located on a pull-out trolley, as well as cables of the pull-out trolley and cables of the battery box, connected by electrical pin-to-socket connectors. Simultaneously with the extension of the trolley, the cables mentioned above are disconnected.

This solution protects the cables from possible mechanical damage, however, it interferes with the use of rechargeable batteries during maintenance due to disconnection of them from the vehicle’s onboard network when the carriage is extended.

Movable plastic cable channels made of articulated joints and designed to protect the movable sections of power cables are known in the art.

The design of cable channels is known, for example, from the descriptions of patents SU 388423, IPC F16G 13/16, publ. 06/22/1973, US 5638672 A, IPC F16G 13/16, publ. 06/17/1997, US 6940019 B2 , IPC F16L 3/00, publ. September 6, 2005. The links of the cable channels are equipped with stops for limiting the angle of rotation, which ensure the movement of the cable channel around the circumference in only one direction. Because of this feature of cable channels, a significant amount of space is allocated in machine designs to enable them to be moved.

From the description of the patent US 6065278 A, IPC F16G 13/16, publ. 05/23/2000, a known type of cable channel, in which each link is equipped with a pair of holes for docking with adjacent links.

Manufacturers of battery boxes in conditions of limited internal space are forced to place a shorter cable inside the box than is necessary for convenient maintenance of the batteries in the battery box of the vehicle.

For the closest analogue of the claimed adopted battery box, known from patent RU 157084 U1, IPC B60R 16/04, publ. November 20, 2015, which includes a case with horizontal shelves installed in the upper part of the case, a retractable trolley with a pallet for rechargeable batteries, horizontally oriented cable channels resting on horizontal shelves and assembled from links equipped with stops to limit the rotation angle cable channel, and cables installed in cable channels.

The disadvantage of the closest analogue is the inconvenience of maintenance, due to the insufficient length of the cables with the fully extended position of the retractable trolley.

The task to which the utility model is directed is to increase the length of cables used in the battery box to increase the convenience of maintenance.

The technical results that the utility model aims to achieve consist in placing a cable protected by a cable channel having a long length in the battery box housing and increasing the convenience of servicing the batteries in the battery box of the diesel locomotive.

The above technical results are achieved in the battery box, which includes a case with horizontal shelves installed in the upper part of the case, a retractable trolley with a pallet for batteries, horizontally oriented cable channels resting on horizontal shelves and assembled from links equipped with stops for limiting the angle of rotation of the cable channel, and cables installed in the cable channels.

These technical results are achieved by the fact that the cable channels are made of two parts, connected mechanically and oriented so that these parts provide rotation of the cable in opposite directions. In this case, the extreme links of the connected parts of the cable channel can be provided with fixing holes and connected by two inserts made in the form of a plate with holes.

The utility model is illustrated by the following images.

In FIG. 1 shows the battery box assembly (trolley extended);

In FIG. 2 shows a part of the box with cable and cable channel (trolley pushed in).

In FIG. 3 shows a diagram of an embodiment for connecting parts of a cable channel.

With reference to FIG. 1-3 are indicated:

1 - battery box housing;

2 - means of attachment to the locomotive frame;

3 - retractable trolley;

4 - retractable trolley mechanism;

5 - a tray for rechargeable batteries;

6 - rechargeable batteries;

7 - cable;

8 - cable channel cable 7;

9 - cable;

10 - cable channel cable 9;

11 - horizontal shelf;

12 - insert for connecting parts of the cable channel.

The utility model can be successfully implemented in the design of the battery box, which includes (see Fig. 1) case 1 with means 2 for fastening to the locomotive frame and horizontal shelves 11 installed in the upper part of the case 1, a retractable trolley 3 with a frame and a front panel movably mounted in the housing 1 by means of a pull-out mechanism 4, a tray 5 for batteries 6 located on the pull-out trolley 3, as well as cables 7, 9 enclosed in horizontally oriented cable channels 8, 10, the links of which are provided with stops for restrictions on the angle of rotation of the cable channel. Cable channels are installed inside the housing 1 on the horizontal shelves 11 and are connected by opposite ends respectively to the rear wall of the housing and to the frame of the retractable trolley 3.

To implement the utility model, the following changes are made in the design of the battery box. Cables 7, 9 and cable channels 8, 10 are of increased length. In this case, the cable channels 8.10 are made up of two parts, the links in which are provided with stops to limit the angle of rotation, and mechanically connect the extreme links of the parts so that the parts provide the cable to rotate in opposite directions (see Fig. 2).

The mechanical connection of the extreme links of the cable channel parts can be implemented in different ways. For example, the extreme links can be connected by an adapter made in the form of a section of a profile of a closed section.

It is easiest to implement the claimed technical solution using cable channels, the links in which are provided with a pair of holes, for example, as described in US Pat. No. 6,065,278 A. In this case, the extreme links of the cable channel parts are connected using two connecting inserts 12 made in the form plates with mounting holes. To connect the extreme links with the inserts use pins made of plastic material or threaded fasteners (not shown in Fig. 3).

Boxing is used in a known manner.

As part of the diesel locomotive, the batteries 6 are located in the pallet 5 inside the housing 1 and are connected to the on-board network of the diesel locomotive by cables 7.9, which are located in the upper part of the housing 1 and are protected by cable channels 8.10, which are supported on horizontal shelves 11.

When conducting maintenance of the batteries 6 push the trolley 3 out of the housing 1 of the box. In this case, the cable channels 8.10, supported by horizontal shelves 11, are straightened, and the cables 7, 9 are pulled out, providing full extension of the trolley 3 with the rechargeable batteries 6. The rechargeable batteries 6 can be disconnected from the on-board if necessary vehicle network.

After completing the maintenance of the rechargeable batteries 6, the trolley 3 is pushed into the housing 1. In this case, the cable channels 8, 10 are folded along an S-shaped path along the horizontal shelves 11, providing a compact arrangement of cables 7, 9 having an increased length.

Conducted patent research confirmed the world novelty of the utility model.

Tests of the prototype battery box confirmed the industrial applicability of the utility model and its compliance with the stated technical results.
