Description

Technical Field:

[0001] The present invention relates to the technical field of track cleaning, and particularly to a track sand burial monitoring device and a processing method. Background Art:

[0002] The railway consists of a subgrade, a roadbed, ballast, sleepers, and tracks from bottom to top, so it is generally higher than the ground. In the areas where the railway passes through desert regions, before the railway was built, the ground had no obvious undulations, and the wind and sand could blow through unobstructed. When the railway is built, due to the obstruction of the railway embankment, the wind and sand will slow down or form vortices near the railway, and the sand carried by the wind and sand will fall on the track, forming track sand accumulation.

[0003] After the track sand accumulation gradually accumulates, it will bury the track, causing potential safety hazards during driving. The existing track sand burial monitoring mostly uses cameras installed on trains for monitoring, and locates in areas with serious sand burial, and then manually cleans it later. In the situation where the sand burial situation is unclear, the train needs to stop and wait for manual cleaning, and there is no self-cleaning method, which greatly delays the journey and causes train delays; especially in stormy weather, the sand burial amount is small but accumulates rapidly, the information collected by the camera is imperfect, the manual cleaning amount is large, and there is no self-processing method. Summary of the Invention:

[0004] In view of this, it is necessary to design a track sand burial monitoring device and a processing method that can overcome the above problems, directly clear the areas with less sand burial, collect complete image information after clearing the areas with more sand burial, and allow the train to pass directly. And conduct positioning, and later manually clean the surrounding area.

[0005] In a first aspect, a track sand burial monitoring device includes: a moving vehicle body that is clamped to the train and travels along the track;

[0006] Guide wheel sets that are matched with the track are arranged on both sides of the moving vehicle body;

[0007] Each guide wheel set includes: an upper wheel that rotates in contact with the upper surface of the track, and a side wheel located on the inner side of the I-shaped track; wherein,

[0008] The side wheel is filled with magnetorheological fluid inside; when the magnetorheological fluid is in the Bingham fluid characteristic, the side wheel rotates in contact with the inner side of the I-shaped track;

[0009] Sand guiding mechanisms are symmetrically arranged on both sides of the moving vehicle body, and the two sand guiding mechanisms rotate away from each other; any one of the sand guiding mechanisms is synchronously rotated with the guide wheel set on the same side through a gear mechanism;

[0010] A shovel plate mechanism is also provided at the front end of the mobile vehicle body. The shovel plate mechanism is used to divert the buried sand covering the track and then introduce it onto two sand guiding mechanisms to be dispersed to both sides of the track.

[0011] A camera assembly and a GPS positioning device are also installed on the mobile vehicle body. Both the camera assembly and the GPS positioning device are connected to the manual monitoring platform.

[0012] Preferably, a hook is connected to the rear end of the mobile vehicle body through a shock absorber rod group, and the hook is connected to the train in a clamping manner.

[0013] Preferably, each set of guiding wheels includes at least two upper wheels and two side wheels.

[0014] Preferably, the gear mechanism includes: a gear box connecting the adjacent upper wheel and side wheel;

[0016] A third bevel gear meshed with the first bevel gear is also arranged inside the gear box;

[0017] Shaft rods are connected between the gear boxes on the same side, and both ends of the shaft rod are coaxially rotatably connected to the third bevel gears of the corresponding gear boxes;

[0018] The gear mechanism further includes a first sprocket sleeved on the shaft rod, and the first sprocket drives the corresponding sand guiding mechanism to rotate through a chain.

[0019] Preferably, each sand guiding mechanism includes: a plurality of guiding rollers distributed in a rectangular shape, and a conveyor belt sleeved on the outer periphery of the plurality of guiding rollers; wherein,

[0020] Rubber teeth are circumferentially arranged on the inner side of the conveyor belt;

[0021] Each sand guiding mechanism further includes a driving gear meshed with the rubber teeth, and a second sprocket matched with the chain is installed on the driving gear.

[0022] Preferably, a plurality of protrusions are circumferentially arranged on the outer side of the conveyor belt.

[0023] Preferably, the side wheel is a rubber wheel body that limits the deformation direction of the magnetorheological fluid;

[0024] An electromagnetic generating device electromagnetically connected to the magnetorheological fluid is arranged on the mobile vehicle body.

[0025] Preferably, the shovel plate mechanism includes a front shovel plate that extends in an arc to the top of the moving vehicle body and cooperates with the two sand guiding mechanisms;

[0026] The plane of the tip of the front shovel plate is higher than the upper surface of the track, and a diversion sharp angle is provided in the middle of the front shovel plate.

[0027] Preferably, side shovel plates are symmetrically and rotatably connected to both sides of the front shovel plate, and the side shovel plates are connected to the front shovel plate through an electric telescopic mechanism.

[0028] In the present invention, the train thrust is used to remove the buried sand, so that the camera assembly can collect clear images and obtain complete information of the track. For areas with severe buried sand or areas that will be buried again after cleaning, a GPS positioning device is used for positioning, and later manual cleaning is carried out around the track to enhance the monitoring effect, ensure high safety, and at the same time reduce shift delays caused by buried sand.

[0029] In a second aspect, a method for treating buried sand on a track includes the following steps:

[0030] Match the guiding wheel set of the moving vehicle body to the track and connect the moving vehicle body to the train;

[0031] The moving vehicle body moves on the track along with the train, and the camera assembly transmits the track condition to the manual monitoring platform;

[0032] When the camera assembly collects that the track is in a state of being buried by wind and sand, the manual monitoring platform prompts the train console to reduce the speed, the electromagnetic generating device controls the magnetorheological fluid to be in the Bingham fluid characteristic, and the side wheels rotate along the inner side surface of the I-shaped track; control the side shovel plates to fit the inner side surface of the I-shaped track to clean the buried sand;

[0033] When the moving vehicle body comes into contact with the buried sand on the track, the diversion sharp angle on the front shovel plate diverts the buried sand along the middle position of the track, and the tip of the front shovel plate lifts the buried sand and guides it along the arc extension onto the sand guiding mechanism for dispersion;

[0034] The two sand guiding mechanisms respectively clean the buried sand outward, and the moving vehicle body disperses the buried sand on both sides of the track synchronously during the forward movement;

[0035] The GPS positioning device sends the positioning information of the severely buried sand area to the manual monitoring platform, and later manual cleaning is carried out;

[0036] After passing through the buried sand section, the side shovel plates are retracted, and the electromagnetic generating device controls the magnetorheological fluid to be in the Newtonian fluid characteristic, which is convenient for the train to turn or change tracks.

[0037] In the present invention, by adopting the above method, areas with less sand burial and areas with more sand burial can both be cleared for the normal passage of trains; when the amount of sand burial is large, the front shovel plate diverts the sand burial and directly guides it to both sides of the track. Part of the remaining sand burial is upwardly guided and then divided and guided by the sand guiding mechanism. During the sand guiding process, the side wheels play a stabilizing role to prevent the moving vehicle body from derailing; at the same time, when turning or changing tracks, the side wheels elastically contract, passing through the gap of track change, and the overall reliability is strong, with the advantage of autonomously clearing sand burial.

Detailed Embodiments:

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0046] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by those of ordinary skill in the art to which this disclosure pertains.

Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0048] To facilitate the understanding of the track buried sand monitoring device and processing method provided in the embodiments of this application, first, its application scenario is described. After the track accumulated sand gradually accumulates, it will bury the track, posing a safety hazard during driving. Existing track buried sand monitoring mostly uses installing cameras on trains, etc. for monitoring, and positioning in areas with severe buried sand, followed by manual cleaning later. In the situation where the buried sand condition is unclear, the train needs to stop and wait for manual cleaning, without a self-cleaning method, which greatly delays the journey and causes train schedule delays; especially in stormy weather, the amount of buried sand is small but accumulates rapidly, the information collected by the camera is incomplete, and the amount of manual cleaning is large, without a self-processing method. In view of this, it is necessary to design a track buried sand monitoring device and processing method that can overcome the above problems, directly clear and pass through areas with less buried sand, collect complete image information after clearing areas with more buried sand, and let the train pass directly. And perform positioning, and later manually clean the surrounding area.

[0049] Refer to the attached Figure 1 attachment Figure 1 is a schematic structural diagram of the track buried sand monitoring device provided by the present invention. The track buried sand monitoring device and processing method include: a moving vehicle body 200 that is clamped to the train and travels along the track 100. When specifically clamping the moving vehicle body 200 to the train, in this application, the train is used to push the moving vehicle body 200 to move, and then the rear end of the moving vehicle body 200 is connected with a hook 201 through a shock absorber rod group 202, and the hook 201 is clamped and connected to the train.

[0050] Specifically, the train is connected to the moving vehicle body 200 by a hook 201 for propulsion. However, the train needs to be equipped with electric control components such as multi-axis robotic arms or lifting rods to provide downward pressure and forward thrust to the moving vehicle body 200, so as to prevent the moving vehicle body 200 from being unable to run stably on the track 100 due to its relatively light own weight. In the event of an external emergency, such as when the moving vehicle body 200 derails, the moving vehicle body 200 can be reinstalled on the track without the train stopping. Guide wheel sets matching the track 100 are provided on both sides of the moving vehicle body 200; each guide wheel set includes: an upper wheel 205 that rotates in contact with the upper surface of the track 100, and a side wheel 206 located on the inner side surface of the I-shaped track 100; and each guide wheel set includes at least two upper wheels 205 and two side wheels 206. The adjacent upper wheel 205 and side wheel 206 are vertically distributed; in the embodiment of the present application, the number of upper wheels 205 and side wheels 206 is two on each side.

[0051] The upper wheel 205 has a conical structure identical to that of a train wheel. The side wheel 206 is used to assist the moving vehicle body 200 in running on the track 100 to prevent derailment. However, when the train turns or changes tracks, the track 100 changes and the track change gap is small. The side wheel 206 needs to undergo a small amount of deformation before it can pass normally; for this reason, magnetorheological fluid is installed inside the side wheel 206; when the magnetorheological fluid is in the Bingham fluid characteristic, the side wheel 206 rotates in contact with the inner side surface of the I-shaped track 100. When the side wheel 206 rotates in contact with the inner side surface of the I-shaped track 100, it provides a greater stabilizing effect for the upper wheel 205 and prevents the moving vehicle body 200 from derailing after shaking up and down when shoveling buried sand.

[0052] The side wheel 206 is a rubber wheel body that limits the deformation direction of the magnetorheological fluid; the rubber wheel body has a hollow cavity and can undergo elastic changes according to the characteristics of the magnetorheological fluid. When passing through the gap during track change, the rubber wheel body deforms and rotates slowly with the train. Of course, a multi-axis robotic arm or a lifting rod can also be used to drive the moving vehicle body 200 to pass through a special section and then place it on the track 100. An electromagnetic generating device 208 that is electromagnetically connected to the magnetorheological fluid is provided on the moving vehicle body 200. The electromagnetic generating device 208 is used to generate different magnetic fields to change the characteristics of the magnetorheological fluid. During the movement of the moving vehicle body 200 along the track 100, the side wheel 206 is in a rotating state. Therefore, the electromagnetic generating device 208 can be optionally connected to its fixed shaft to conduct the magnetic field, or an electromagnetic coil can be provided inside the side wheel 206, and the characteristics of the magnetorheological fluid can be changed by wirelessly controlling the magnetic field change of the electromagnetic coil. These are all existing well-known technologies and will not be elaborated here.

[0053] The magnetorheological fluid used is a kind of "intelligent" fluid, which forms a suspension by uniformly dispersing and immersing micron-sized or nanometer-sized ferromagnetic particles in a non-magnetic mother carrier fluid and additives. Under the action of an external magnetic field, its fluid characteristics can be changed.

[0054] In a high magnetic field strength environment, it exhibits the characteristics of a Bingham fluid with low fluidity and high viscosity; in a weak magnetic field strength environment, it exhibits the characteristics of a Newtonian fluid with high fluidity and low viscosity. It can achieve a stepless change between high and low viscosities of the fluid within milliseconds, thereby realizing a stepless adjustment of the main spring stiffness damping.

[0055] Combined Figure 2 and Figure 3 As shown in

[0056] and

[0057] In Figure 2 it can be seen that the tip of the front shovel plate 211 is chamfered, effectively avoiding hard contact with the track 100. Of course, a small amount of buried sand remaining on the track 100 will not have any impact on the train passing. A diversion sharp corner 212 is provided in the middle of the front shovel plate 211.

[0058] Side shovel plates 210 are symmetrically and rotatably connected to both sides of the front shovel plate 211, and the side shovel plates 210 are connected to the front shovel plate 211 through electric telescopic mechanisms 224. From Figure 3As can be seen, the side shovel plate 210 has inner convex blocks 213 that match the I-shaped outer side surface of the track 100. When the electric telescopic mechanism 224 extends, the inner convex blocks 213 enter the I-shaped outer side surface of the track 100, causing the buried sand near the track 100 to move away. Since most of the buried sand is loose and the side wheels 206 rotate in a circumferential manner in the vertical state, multiple treads are provided on the outer surface of the rubber wheel body. Under the strong push and pull of the train, the buried sand on the I-shaped inner side surface of the track 100 can be quickly cleared. Of course, in another embodiment of the present application, in order to provide a smoother passage track 100 for the side wheels 206, a shovel plate opposite to the side shovel plate 210 can also be connected to the front shovel plate 211 through an electric telescopic rod to remove the buried sand on the I-shaped inner side surface of the track 100.

[0059] Continue to refer to Figure 4 and Figure 5 , sand guiding mechanisms 209 are symmetrically arranged on both sides of the moving vehicle body 200, and the two sand guiding mechanisms 209 rotate away from each other; it should be understood that the left sand guiding mechanism 209 rotates to guide sand to the left, and the right sand guiding mechanism 209 rotates to guide sand to the right.

[0060] Any one of the sand guiding mechanisms 209 rotates synchronously with the guide wheel set on the same side through a gear mechanism; the gear mechanism includes: a gear box 207 connected between the adjacent upper wheel and the side wheel 206; by adopting the synchronous rotation method and combining with the strong push and pull of the train, the application is more superior than that powered by a battery.

[0061] Inside the gear box 207, a first bevel gear 214 coaxially connected to the upper wheel and a second bevel gear 215 coaxially connected to the side wheel 206 are provided; the first bevel gear 214 and the second bevel gear 215 are meshed and connected; a third bevel gear 216 meshed with the first bevel gear 214 is also provided inside the gear box 207; a shaft rod is connected between the gear boxes 207 on the same side, and both ends of the shaft rod are coaxially rotatably connected to the third bevel gears 216 of the corresponding gear boxes 207; the gear mechanism further includes a first sprocket 222 sleeved on the shaft rod, and the first sprocket 222 drives the corresponding sand guiding mechanism 209 to rotate through a chain 223.

[0062] As Figure 5As shown in the figure, each sand guiding mechanism 209 includes: a plurality of guiding rollers 219 distributed in a rectangle, and a conveyor belt sleeved around the plurality of guiding rollers 219; wherein, rubber teeth 217 are circumferentially arranged on the inner side of the conveyor belt; each sand guiding mechanism 209 further includes a driving gear 220 meshing with the rubber teeth 217, and a second sprocket 221 fitted on the driving gear 220 and cooperating with a chain 223. A plurality of protrusions 218 are circumferentially arranged on the outer side of the conveyor belt. It can be seen from this that under the action of the gearbox 207, the rotational force of the upper wheel 205 and the side wheel 206 is reversed to drive the first sprocket 222 to rotate. Under the action of the first sprocket 222, the second sprocket 221 is driven to rotate, so that the driving gear 220 drives the corresponding rotation of the sand guiding mechanism 209. In areas with a large amount of buried sand, the diversion pointed plate separates the buried sand to both sides in advance, and makes the remaining buried sand on the track 100 be upwardly introduced into the sand guiding mechanism 209 for dispersed transportation.

[0063] The mobile vehicle body 200 is further equipped with a camera assembly 204 and a GPS positioning device 203, and both the camera assembly 204 and the GPS positioning device 203 are connected to the artificial monitoring platform. By cleaning the buried sand, the camera assembly 204 obtains complete and clear video information for transmission. In areas with a large amount of buried sand, the GPS positioning device 203 is used to locate this area, and after the train passes, it notifies the artificial to handle it in time to avoid burying the track 100 again.

[0064] In the present invention, the train thrust is used to remove the buried sand, so that the camera assembly can collect clear images and obtain complete information of the track. For areas with serious buried sand or areas that will be buried again after cleaning, the GPS positioning device is used for positioning, and later the artificial clears the periphery of the track, enhancing the monitoring effect, ensuring high safety, and at the same time reducing the shift delays caused by buried sand, etc.

[0065] In addition, the present invention also provides a method for treating buried sand on a track, including the following steps:

[0066] S1. Match the guiding wheel set of the mobile vehicle body to the track and connect the mobile vehicle body to the train;

[0067] S2. The mobile vehicle body moves on the track along with the train, and the camera assembly transmits the track conditions to the artificial monitoring platform;

[0068] S3. When the camera assembly collects that the track is in a state of being buried by wind and sand, the artificial monitoring platform prompts the train console to reduce the speed, the electromagnetic generating device controls the magnetorheological fluid to be in the Bingham fluid characteristic, and the side wheels rotate along the inner side surface of the I-shaped track; control the side shovel plate to fit the inner side surface of the I-shaped track for buried sand cleaning;

[0069] S4. When the moving vehicle body comes into contact with the buried sand on the track, the diversion sharp corners on the front shovel plate divert the buried sand along the middle position of the track, and the tip of the front shovel plate lifts the buried sand and guides it along an arc to be dispersed onto the sand guiding mechanism;

[0070] S5. The two sand guiding mechanisms respectively clean the buried sand outward, and the moving vehicle body disperses the buried sand on both sides of the track synchronously during the forward movement;

[0071] S6. The GPS positioning device sends the positioning information of the areas with serious buried sand to the artificial monitoring platform for later manual cleaning;

[0072] S7. After passing through the buried sand section, the side shovel plates are retracted, and the electromagnetic generating device controls the magnetorheological fluid to be in the Newtonian fluid characteristic, which is convenient for the train to turn or change tracks.

[0073] In the present invention, by adopting the above method, both the areas with less buried sand and the areas with more buried sand can be cleared for the normal passage of the train; when the amount of buried sand is large, the front shovel plate diverts the buried sand and directly guides it to both sides of the track, and part of the remaining buried sand is guided upward and then divided and guided by the sand guiding mechanism. The side wheels play a stabilizing role during the sand guiding process to prevent the moving vehicle body from derailing; at the same time, when turning or changing tracks, the side wheels generate elastic contraction and pass through the gap of the track change, and the overall reliability is strong, having the advantage of autonomously clearing the buried sand.
