Description

Technical Field

[0001] The present application relates to the field of track cleaning, and in particular to a track cleaning device for rail transportation. Background Art

[0002] Subway is a fast, high-capacity, electric-powered rail transit system built in cities. Trains run on fully enclosed lines. Lines in the central urban area are basically located in underground tunnels, while lines outside the central urban area are generally located on viaducts or on the ground. Subway is a high-density, high-capacity urban rail transit system that covers all kinds of underground and above-ground road rights in urban areas.

[0003] When the train is running, there will be some natural sediments and human remains such as sand, dirt, leaves, garbage, etc. on the track. These debris may affect the normal contact between the train wheels and the track, causing increased driving noise, increased wear, and even affecting driving safety. Due to the complex internal environment of the subway track and the existence of safety hazards such as high voltage electricity and high-speed trains passing, it is not convenient to clean it manually. Therefore, it is necessary to use a track cleaning equipment to clean the track. A track cleaning equipment for rail transit is proposed.

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application embodiment discloses a track cleaning device for rail transportation. Figure 1-5 , a track cleaning device for rail transportation, comprising a mounting frame 1, a driving assembly is provided on the mounting frame 1, two cleaning brushes 6 for cleaning a track body 101 are connected to the driving assembly, the two cleaning brushes 6 are in contact with the surface of the track body 101, the driving assembly is used to drive the two cleaning brushes 6 to rotate on the surface of the track body 101 at the same time, two pre-cleaning frames 14 are provided on the mounting frame 1, the two pre-cleaning frames 14 are located in front of the two cleaning brushes 6, and a moving part is provided on the mounting frame 1;

[0023] It should be noted that one driving assembly drives two cleaning brushes 6 to rotate simultaneously, which can ensure that the two cleaning brushes 6 remain synchronized when working, and help to evenly distribute the cleaning force. Compared with two independently driven cleaning brushes 6, shared drive can more effectively utilize energy, reduce energy consumption, and improve energy efficiency during operation.

[0024] It should be further explained that the distance between the track bodies 101 is 1435 mm according to the standard track gauge;

[0025] By adopting the above technical solution, when in use, the moving part drives the mounting frame 1 to move along the track body 101, the two pre-cleaning frames 14 sweep away large particles of debris such as sand, gravel, leaves, garbage, etc. on the track body 101, and the driving component drives the two cleaning brushes 6 to clean the fine dust, oil stains, etc. on the surface of the track body 101, thereby reducing repeated operations and improving cleaning efficiency.

[0026] Reference Figure 1 , 2 The driving assembly includes a connecting shaft 2, a primary driven gear 3, a secondary driving gear 4, a secondary driven gear 5, a support frame 7, a primary driving gear 8, and a motor 9. The connecting shaft 2 is clearance-matched with the mounting frame 1. The primary driven gear 3 is fixed to the top of the connecting shaft 2. The support frame 7 is rotatably connected to the bottom end of the connecting shaft 2. The support frame 7 is fixed to the mounting frame 1. The secondary driving gear 4 is fixed to the connecting shaft 2. The secondary driving gear 4 is meshed with the secondary driven gear 5. The secondary driven gear 5 is fixedly connected to the cleaning brush 6. The primary driven gear 3 is meshed with the primary driving gear 8. The rotor end of the motor 9 is fixed to the primary driving gear 8.

[0027] By adopting the above technical solution, the starting motor 9 rotates the first-stage driving gear 8, which in turn drives the first-stage driven gear 3 to rotate. The first-stage driven gear 3 drives the connecting shaft 2 and the second-stage driving gear 4 and the second-stage driven gear 5 thereon to rotate, thereby causing the cleaning brush 6 to rotate on the surface of the track body 101 for cleaning.

[0033] It should be noted that a fixing plate is fixed on the mounting frame 1, a connecting frame is fixed at the bottom of the fixing plate, and the moving wheel 10 rotates in the connecting frame;

[0034] By adopting the above technical solution, the second motor 11 is started to rotate one of the moving wheels 10, thereby driving the other moving wheels 10 to rotate, thereby moving the mounting frame 1 and the cleaning brush 6 and the pre-cleaning frame 14 thereon on the track body 101 to perform cleaning operations.

[0036] By adopting the above technical solution, the fixed cooperation between the connecting column 12 and the supporting frame 13 makes the operation of the pre-cleaning frame 14 more stable. At the same time, the pre-cleaning frame 14 cleans up the large particles of debris on the track body 101 by moving. The pre-cleaning brush 15 cooperates with the pre-cleaning frame 14 to clean the large particles of debris on the side of the track body 101 to prevent the large particles of debris from affecting the normal operation of the train.
