Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of track maintenance, in particular to a cleaning device for track maintenance. BACKGROUND

[0002] Track usually refers to railway track, which is used to support the running of trains along the direction of the track laying, and is usually composed of two parallel tracks fixed on sleepers. The track is of an I-shaped structure, the end surface of the top of which is in contact with the wheels of the train and bears pressure, and the train travels by the friction between the wheels and the track.

[0003] Since the track is closely related to the safety of train travel, it needs to be maintained regularly. After long-term use of the track, a thin layer of rust (mainly brown iron oxide) and stubborn oil stains, metal powder mixture and other pollutants are usually generated on the surface of the track, which makes the surface of the track uneven or even changes the overall shape. In order to ensure the safe running of trains on the track, the pollutants on the surface of the track need to be removed during maintenance.

[0004] The existing track surface pollutants are usually removed by manual or mechanical polishing. Although manual polishing can remove the pollutants on the surface of the track more comprehensively, it is time-consuming and costly, and the removal effect is unstable. Moreover, the existing mechanical polishing, although more efficient and less costly, mainly polishes the top surface of the track, and the pollutants are not removed comprehensively, which still affects the service life of the track. SUMMARY

[0005] The present application provides a cleaning device for track maintenance, which can comprehensively remove the pollutants on the surface of the track, effectively improve the removal efficiency and effect, and effectively prolong the service life of the track, thereby effectively ensuring the safety of train travel along the track.

[0044] The following will be described in detail with reference to the accompanying drawings Figures 1-4 The present application will be further described in detail.

[0045] Reference will be made to Figure 1 and Figure 2The embodiment of the application discloses a cleaning device for track maintenance, which is used for overall polishing the surface of a rail 1, prolongs the service life of the rail 1 and improves the safety of train driving along the rail. In the embodiment, the track preferably comprises two mutually parallel rails 1, and the cross section of the rail 1 is in the shape of an I. The rail 1 has an arc surface on both sides of the width direction of the top, and the transition area between the top and the waist of the rail 1 is a bevel.

[0048] Referring to Figure 1 and Figure 4 , the driving mechanism 3 is installed at the bottom of the body 2, and comprises four wheels 31 and a first driving member 32 for driving the wheels 31 to rotate.

[0049] The wheel 31 is in the shape of a cylinder, and a groove matched with the top of the rail 1 is formed in the circumferential side of the wheel 31, so that the wheel 31 can keep the matching relationship with the rail 1 after being positioned and placed on the rail 1. The wheel 31 is rotationally connected with the body 2, the rotation axis of the wheel 31 coincides with the axis of the wheel 31 and is parallel to the width direction of the body 2, and the four wheels 31 are distributed at both ends of the width direction of the body 2 and at both ends of the length direction of the body 2. In the embodiment, the wheel 31 with the above function is a common prior art, so the wheel 31 is not described in detail, and only a brief representation of the wheel 31 is shown in the drawings.

[0050] The first driving member 32 is fixedly installed at the bottom of the body 2, and is used for driving the wheel 31 to rotate relative to the body 2. In the embodiment, the first driving member 32 is preferably a servo motor; and the first driving member 32 is used for driving the two wheels 31 located at the rear of the body 2 along the moving direction of the body 2 to rotate (i.e. the driving mechanism 3 drives the body 2 to move along the rail 1 in a rear-driven mode).

[0051] Referring to Figure 2 and Figure 3The polishing mechanism 4 comprises two first polishing assemblies 41 for polishing the top surface of the rail 1 and two second polishing assemblies 42 for polishing the waist surface of the rail 1, and the two first polishing assemblies 41 and the two second polishing assemblies 42 correspond to the two rails 1 respectively; the first polishing assembly 41 and the second polishing assembly 42 are located between the two front and rear wheels 31, and the first polishing assembly 41 is located in front of the second polishing assembly 42 (that is, the same area of the rail 1 will be polished on the top surface and then on the waist surface by the polishing mechanism 4).

[0052] The first polishing assembly 41 comprises a first polishing piece 411, the first polishing piece 411 is located above the corresponding rail 1, and the bottom of the first polishing piece 411 is used to abut and contact the surface of the top of the rail 1 (the top surface, the side surface and the arc surface between the two surfaces), at this time the first polishing piece 411 can polish the surface of the top of the rail 1 during the movement of the machine body 2 along the rail 1.

[0053] The second polishing assembly 42 comprises two second polishing pieces 421, the two second polishing pieces 421 are located on the two sides of the corresponding rail 1 respectively, and the second polishing piece 421 can move horizontally relative to the machine body 2 so that one side of the second polishing piece 421 abuts and contacts the surface of the waist of the rail 1, at this time the second polishing piece 421 can polish the surface of the waist of the rail 1 during the movement of the machine body 2 along the rail 1.

[0054] The water storage device comprises a water storage tank 51 for storing water, a cooling assembly 52 for cooling the surface of the rail 1, and a flushing assembly 53 for flushing the pollutants such as metal scraps on the surface of the rail 1.

[0055] The water storage tank 51 is fixedly installed on the top of the machine body 2, and has a space inside for storing the water required by the cooling assembly 52 and the flushing assembly 53.

[0056] The cooling assembly 52 comprises a water storage box 521 for storing cooling water and two cooling nozzles 522 for spraying water to cool the top of the rail; a lifting platform 21 is movably installed on the machine body 2 in the vertical direction above the first polishing piece 411, a plurality of elastic members 22 are connected and installed between the lifting platform 21 and the machine body 2, the top of the first polishing piece 411 is fixedly connected with the bottom of the lifting platform 21, and the water storage box 521 is fixedly installed on the top of the lifting platform 21.

[0057] The inside of the water storage box 521 has a space for storing the cooling water, and the inside space is much smaller than the inside space of the water storage tank 51; a pipeline for water transportation is connected between the water storage tank 51 and the water storage box 521, and the pipeline is controlled by the staff to drive the water in the water storage tank 51 to flow into the inside space of the water storage box 521 according to the demand. In this embodiment, a water pump for achieving the above effect is fixedly installed on the pipeline between the water storage tank 51 and the water storage box 521; since the water pump is a common prior art, it will not be described here, and it is only briefly indicated in the drawings.

[0058] The lifting platform 21 has a limit in the process of moving relative to the machine body 2, and the elastic member 22 has a tendency to drive the lifting platform 21 to move upward to the limit position; when the lifting platform 21 moves upward to the limit position, the first polishing member 411 keeps a certain distance from the surface of the top of the rail 1; after the lifting platform 21 moves downward, the first polishing member 411 is in contact with the surface of the top of the rail 1; the staff controls the amount of water in the inside space of the water storage box 521 to control the lifting platform 21 to move up and down relative to the machine body 2, and the first polishing member 411 moves up and down with the lifting platform 21 to adapt to the rail 1 of different height sizes. In this embodiment, the elastic member 22 is preferably a compression spring.

[0059] At this time, the staff can determine the degree of polishing required for the top surface of the rail 1 according to the pollution of the top surface of the rail 1, so as to determine the position of the first polishing member 411 relative to the rail 1 when the first polishing member 411 polishes the top surface of the rail 1, and then control the amount of water in the water storage box 521 to make the first polishing member 411 maintain the polishing degree of the top surface of the rail 1 during the polishing process; and when the first polishing member 411 is worn during the process of polishing the top surface of the rail 1, the polishing degree of the first polishing member 411 on the top surface of the rail 1 is insufficient, and the amount of water in the water storage box 521 is increased to make the lifting platform 21 move downward, so that the first polishing member 411 restores the previous polishing degree of the top surface of the rail 1. In this embodiment, the bottom of the machine body 2 is preferably fixedly installed with a monitoring instrument for monitoring the polishing effect of the rail 1 after polishing, and the amount of water in the water storage box 521 is controlled according to the monitoring result; since the monitoring instrument with the above function is a common prior art, it will not be described here, and it is omitted in the drawings.

[0060] The cooling nozzle 522 is fixedly installed at the bottom of the machine body 2, and is used for spraying water to the top of the rail 1 for cooling, and the water sprayed to the top of the rail 1 can flow down to the waist surface of the rail 1 under the action of its own gravity, so as to realize overall cooling of the surface of the rail 1. The cooling nozzle 522 is aligned with the adjacent first polishing member 411 along the length direction of the machine body 2, and is located between the adjacent first polishing member 411 and the second polishing member 421 and close to the first polishing member 411. A pipeline for water transmission is connected between the top of the cooling nozzle 522 and the water storage box 521, and a water pump for driving the water in the water storage box 521 to be sprayed out of the cooling nozzle 522 is fixedly installed on the pipeline. In the embodiment, the position of the cooling nozzle 522 between the adjacent first polishing member 411 and the second polishing member 421 and the speed of the traveling mechanism 3 for driving the machine body 2 to move along the rail 1 meet the following effects: for the same area on the rail 1, after the second polishing member 421 polishes the waist surface of the rail 1, the water previously sprayed by the cooling nozzle 522 to the top of the rail 1 will flow down to the waist surface of the rail 1. Since the cooling nozzle 522 with the above function is a common prior art, it will not be described here, and only a brief representation is made in the drawings.

[0061] Further, in order to facilitate installation of the track maintenance cleaning device on the track, meet the polishing requirements of rails 1 with different widths and effectively ensure the polishing degree of the waist surface of the rail 1, the second polishing assembly 42 further comprises two movable arms 422 for controlling the movement of the second polishing member 421, a rotating disc 423 for simultaneously controlling the movement of the two second polishing members, and a third driving member 424 for driving the rotating disc 423 to rotate.

[0062] The rotating disc 423 is in the shape of a disc, and is rotatably installed at the bottom of the machine body 2, with its rotation axis coinciding with its own axis and being vertical. After the track maintenance cleaning device is installed on the track, the rotating disc 423 is aligned with the rail 1 below along the axis direction of the rotating disc 423. The third driving member 424 is fixedly installed in the machine body 2, and is used for driving the rotating disc 423 to rotate relative to the machine body 2. In the embodiment, the third driving member 424 is preferably a servo motor.

[0063] The movable arm 422 is installed at the bottom of the rotating disc 423, and the two movable arms 422 are symmetrically distributed on the rotating disc 423; the movable arm 422 comprises a first arm body 4221, a second arm body 4222 and a second driving member 4223, and the first arm body 4221 and the second arm body 4222 are both in the form of a rod structure as a whole; one end of the first arm body 4221 in the length direction is fixedly connected with the rotating disc 423, one end of the second arm body 4222 in the length direction is rotatably connected with the other end of the first arm body 4221 in the length direction, the rotating axis thereof is parallel to the rotating axis of the rotating disc 423, and the second polishing member 421 is fixedly installed at the other end of the second arm body 4222 in the length direction; the second driving member 4223 is fixedly installed at the top of the first arm body 4221, and is used to drive the second arm body 4222 to rotate relative to the first arm body 4221. In the embodiment, the second driving member 4223 is preferably a servo motor.

[0064] The second arm body 4222 has a limit in the process of rotating relative to the first arm body 4221; when the second arm body 4222 rotates to the limit position in the direction away from the other second arm body 4222, the spacing between the two movable arms 422 is maximum at this time, which is convenient for the track maintenance cleaning device to be installed on the track, and prevents the movable arm 422 from colliding with the rail 1 during the installation process; when the second arm body 4222 rotates to the limit position in the direction close to the other second arm body 4222, the spacing between the two second polishing members 421 is minimum at this time, and at this time, adjusting the second arm body 4222 to rotate relative to the first arm body 4221 by a certain degree can make the second polishing assembly 42 meet the polishing requirements of the waist surface of the rail 1 (adapt to the polishing requirements of the waist surface of the rail 1 of different width sizes and be able to keep the polishing degree of the waist surface of the rail 1 during the polishing process by rotating the rotating disc 423).

[0065] Moreover, when the two second polishing members 421 are worn during the process of polishing the waist surface of the rail 1, resulting in that the polishing degree of the waist surface of the rail 1 is insufficient at this time, the two second polishing members 421 can restore the previous polishing degree of the waist surface of the rail 1 by controlling the rotating disc 423 to rotate. In the embodiment, the second polishing assembly 42 is preferably controlled by the corresponding monitoring instrument for monitoring the polishing effect of the rail 1 after being polished, like the first polishing assembly 41.

[0066] The flushing assembly 53 comprises two flushing nozzles 531 corresponding to the two rails 1. When the track maintenance cleaning device is installed on the track, the flushing nozzles 531 are located above the corresponding rails 1 and are used to spray water on the top of the rails 1. The flushing nozzles 531 are located on the side of the adjacent second grinding piece 421 away from the first grinding piece 411 and between the front and rear wheels 31. The flushing nozzles 531 are fixedly installed on the bottom of the body 2 and are connected to the water storage tank 51 through pipes. A water pump is also installed on the pipes to drive the water in the water storage tank 51 to be sprayed through the flushing nozzles 531.

[0067] At this time, when the flushing nozzles 531 spray water on the top of the rails 1, the pollutants generated after grinding on the top surface of the rails 1 can be washed away. Then, the water flowing down the top surface of the rails 1 can also flush the waist surface of the rails 1, thereby improving the cleanliness of the surface of the rails 1 after grinding and effectively preventing the pollutants from re-attaching to the surface of the rails 1.

[0068] Referring to Figure 3 and Figure 4 Furthermore, in order to speed up the drying of the top surface of the rails 1 after flushing, the rear wheel 31 is preferably provided with a water absorption piece 6 for contacting the top surface of the rails 1.

[0069] The water absorption piece 6 has water absorption property and expands after absorbing water and is squeezed to release water. When the track maintenance cleaning device is installed on the track, the bottom of the water absorption piece 6 contacts and fits the top surface of the rails 1, so that the water absorption piece 6 can absorb the water on the top surface of the rails 1 during the movement of the body 2 along the rails 1. After absorbing water, the water absorption piece 6 is rotated with the wheel 31 to contact the top surface of the rails 1 again and is squeezed to release water. The released water is used to directly flush the waist surface of the rails 1.

[0070] A plurality of water spraying holes 311 are formed on both sides of the rear wheel 31. The water spraying holes 311 are arranged in a circular array on the wheel 31 with the axis of the wheel 31 as the axis. One end of the water spraying hole 311 forms an opening on the surface of the wheel 31 contacting the side surface of the top of the rails 1 and is covered by the water absorption piece 6. The other end of the water spraying hole 311 forms an opening on the circumferential surface of the wheel 31 and sprays water in the direction close to the waist of the rails 1. At this time, when the water absorption piece 6 is squeezed to release water, the squeezed water mainly flows into the adjacent water spraying hole 311 and is finally sprayed in the direction close to the waist surface of the rails 1 under the guidance of the water spraying hole 311.

[0071] Further, in order to improve the effect of the water absorbing member 6 on the surface of the rail 1 after the water is squeezed out through the water injection hole 311, and to facilitate the installation of the track maintenance cleaning device on the track, two baffle plates 7 are preferably fixed on the rear wheels 31.

[0072] The baffle plate 7 is in the shape of a ring plate, and is fixed on both sides of the wheel 31. The space between the two baffle plates 7 is tapered away from the axis of the wheel 31. The baffle plate 7 is elastic, and the minimum distance between the two baffle plates 7 is less than the width of the top of the rail 1. The water injection hole 311 is directed towards the inner surface of the baffle plate 7. In this embodiment, the baffle plate 7 is preferably made of rubber. When the wheel 31 is engaged with the rail 1, the bottom of the baffle plate 7 is elastically deformed by the top of the rail 1. The bottom of the two baffle plates 7 will respectively contact the surface of the top of the rail 1, which can accelerate the drying of the water on the top of the rail 1. The water in the gap between the top of the rail 1 and the baffle plate 7 can flow along the baffle plate 7 towards the surface of the rail 1.

[0073] During the installation of the track maintenance cleaning device on the track, the staff can use the baffle plate 7 as a reference when engaging the rear wheel 31 with the corresponding rail 1. The elastic deformation of the baffle plate 7 can compensate for the position error during installation, and effectively guide the wheel 31 to engage with the corresponding rail 1. After the installation of the track maintenance cleaning device on the track, the bottom of the two baffle plates 7 will be located on both sides of the waist of the rail 1, and the baffle plate 7 will maintain a distance from the rail 1. At this time, part of the washing water sprayed by the water injection hole 311 can flow along the inner surface of the bottom of the baffle plate 7 towards the waist of the rail 1, thereby effectively washing the contaminants attached to the surface of the waist of the rail 1. In this embodiment, the track maintenance cleaning device is preferably installed on the track by hoisting. Since hoisting is a common prior art, it will not be described here.

[0074] The implementation principle of the track maintenance cleaning device according to the embodiment of the present application is as follows:

[0075] After the installation of the track maintenance cleaning device on the track, the running mechanism 3 will drive the body 2 to move along the rail 1. During the movement, the grinding mechanism 4 will simultaneously grind the surface of the rail 1. The water storage mechanism 5 will also cool and wash the ground rail 1. Finally, the water absorbing member 6 will absorb the excess water on the top of the rail 1 and use it to directly wash the surface of the waist of the rail 1.

[0076] In the process that the polishing mechanism 4 polishes the surface of the rail 1, the first polishing piece 411 polishes the top surface of the rail 1 first, then the two second polishing pieces 421 polish the surfaces on both sides of the waist of the rail 1 simultaneously, and the position of the first polishing piece 411 and the second polishing piece 421 can be adjusted according to the actual polishing requirement of the rail 1, so that more polishing requirements of different rails 1 can be met.

[0077] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
