Manual oiling is time-consuming and labor-intensive, and sometimes trains pass by when working on the railway, which has time limitations; the existing oiling cart needs to stop for oiling, which is inefficient, and there are problems such as unstable oiling (oil injection) effect and possible omission of oil injection positions. At the same time, the oiling cart cannot change due to changes in the environment. For example, when there are foreign objects such as stones on the rails and bolts, it often causes obstacles to the operation of the oiling cart, making the oiling cart unable to work normally.

A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] In a first aspect, the present invention provides an intelligent rail fuel injection vehicle, referring to Figure 1-2 , the rail fuel injection vehicle includes a running device 1-10, a fuel injection device, a regulating device, a detection device and a control device;

[0042] The fuel injection device, the regulating device, the detecting device and the control device are installed on the traveling device 1-10. The fuel injector 1-2 in the fuel injection device is installed on the traveling device 1-10 through the fuel injector adjusting module in the regulating device. The inductive sensor 1-7 in the detecting device is installed on the traveling device 1-10 through the inductive sensor adjusting mechanism 1-8 in the regulating device. The control device is respectively connected to the fuel injector adjusting module, the inductive sensor 1-7, the inductive sensor adjusting mechanism 1-8 and the laser distance sensor 1-18 in the detecting device. The laser distance sensor 1-18, the inductive sensor 1-7 and the fuel injector 1-2 are arranged in sequence on the rail fuel injection vehicle in the driving direction of the rail fuel injection vehicle.

[0043] Among them, the laser distance sensor 1-18 is used to measure the height of the object on the track, and the inductive sensor 1-7 is used to determine whether the object is a bolt and detect the position of the bolt. The objects on the track include foreign objects and bolts. The foreign objects are mainly irregular ballast, other non-track objects, etc.; the injector adjustment module and the inductive sensor adjustment mechanism 1-8 can adjust the height of the injector 1-2 and the inductive sensor 1-7 according to the height detected by the laser distance sensor 1-18. The height of the inductive sensor 1-7 is relatively appropriate to that of the foreign object or the bolt. The height of the injector 1-2 should be greater than the height of the foreign object and when encountering the bolt Keep a certain distance from the top of the bolt; the laser distance sensor 1-18, the inductive sensor 1-7 and the fuel injector 1-2 are arranged in sequence on the rail fuel injection vehicle in the direction of travel of the rail fuel injection vehicle. For example: the laser distance sensor 1-18 is arranged on the front end of the rail fuel injection vehicle, the fuel injector 1-2 is arranged on the rear end of the rail fuel injection vehicle, and the inductive sensor 1-7 is arranged between the laser distance sensor 1-18 and the fuel injector 1-2. In other words, if there is an object on the track, when the rail fuel injection vehicle passes the object, the laser distance sensor 1-18 passes first, followed by the inductive sensor 1-7, and finally the fuel injector 1-2.

[0044] Specifically, the rail fuel injection vehicle moves on the rail through the walking device 1-10. During the movement, the laser distance sensor 1-18 first scans and measures the height of the object on the rail and records it, and adjusts the height of the inductive sensor 1-7 and the fuel injector 1-2 according to the height of the object. When the inductive sensor 1-7 passes the object, it detects whether the object is a bolt. If it is a bolt, the height of the fuel injector 1-2 is adjusted so that it can spray normally. For example, when the laser distance sensor 1-18 detects that the height of the object is too high, the inductive sensor adjustment mechanism 1-8 controls the inductive sensor 1-7 to rise to avoid the inductive sensor 1-7 from colliding with the object. At the same time, the fuel injector adjustment module controls the fuel injector 1-2 to rise to avoid the fuel injector 1-2 from colliding with the object. When the inductive sensor 1-7 detects a bolt, the height of the bolt detected by the laser distance sensor 1-18 is adjusted according to the height of the bolt through the fuel injector adjustment module to keep a fixed distance from the top of the bolt so that the fuel injector can spray the bolt normally.

[0045] It should be noted that during the operation of the rail fuel injection vehicle, the distance between the fuel injection nozzle 1-2 and the top of the bolt is determined according to the oil quality.

[0046] In this embodiment, by designing the inductive sensor 1-7 and the laser distance sensor 1-18 to jointly monitor the bolt position, it is possible to effectively avoid accidental injection of foreign objects, improve the efficiency of the rail fuel injection vehicle, and reduce the impact of the environment on the operation of the rail fuel injection vehicle. At the same time, since the laser distance sensor 1-18, the inductive sensor 1-7 and the fuel injector 1-2 are arranged in sequence on the rail fuel injection vehicle in the direction of travel of the rail fuel injection vehicle, the three work together to enable the rail fuel injection vehicle to perform non-stop fuel injection operations.

[0047] In one embodiment, referring to Figure 1-2 The detection device also includes a camera 1-3, which is used to obtain the injection effect of the injector 1-2, and the camera 1-3 is connected to the control device.

[0048] The camera 1-3 is arranged near the fuel injector 1-2 so as to obtain the fuel injection result of the fuel injector.

[0049] In this embodiment, cameras 1-3 are set to capture the effect after oil injection, and the control device is used to screen bolts with poor oil injection effect for easy rework. At the same time, the oil injection time and posture are corrected and adjusted in real time to realize the intelligent oil injection process.

[0050] In one embodiment, referring to Figure 1-2 The rail fuel injection vehicle includes a power device, which is respectively connected to the walking device 1-10, the adjusting device, the detecting device and the controlling device.

[0051] Among them, the power unit provides electricity for the entire vehicle.

[0052] In this embodiment, the power device includes a power battery 1-11, and the power battery 1-11 is installed on the walking device 1-10.

[0053] In one embodiment, referring to Figure 1-2 The rail fuel injection vehicle also includes a lighting device, which is installed on the walking device 1-10.

[0054] The lighting device is used to illuminate the track. Generally, the lighting device is installed at the front and rear ends of the track spraying vehicle. The lighting device is usually set to 1-14 lighting lamps.

[0055] In this embodiment, the lighting device is provided to make the rail fuel injection vehicle suitable for rail fuel injection in multiple time periods, and can also serve as a reminder to others.

[0056] In one embodiment, referring to Figure 1-2 , the control device includes an electric control box 1-13 and a controller.

[0057] Among them, the controller can analyze the injection effect diagram obtained by the camera 1-3, record the object height and bolt position data recorded during the movement of the rail injection vehicle, and the electric control box 1-13 can control the selection parameters.

[0058] In one embodiment, referring to Figure 1-2 The oil injection device also includes a time relay, which is connected to the oil injection valve 1-1. When the inductive sensor 1-7 detects the bolt, the distance between the inductive sensor 1-7 and the laser distance sensor 1-18 is fixed; when the trolley moves forward a certain displacement, the laser distance sensor 1-18 detects the height of the bolt, and adjusts the height of the oil injection nozzle 1-2 in real time, starts the pneumatic pump to spray the oil onto the bolt, and calculates the duration of the oil injection according to the speed of the equipment. After the time is reached, the time relay controls the automatic shutdown of the oil injection. After the oil injection, the camera 1-3 records the injection position and effect, and uploads the data to the controller, which solves the problems of the existing oil injection method, such as low oil injection efficiency and the inability to guarantee the oil injection effect.

[0059] In one embodiment, referring to Figure 1-2 The walking device 1-10 includes a chassis 1-17, wheels and a driving motor. Two pairs of wheels are arranged under the chassis 1-17. Each pair of wheels is connected by a rolling shaft. The rolling shaft of one pair of wheels is transmission-connected to the driving motor, and the driving motor is connected to the power device.

[0060] Among them, you can refer to Figure 1-2 The chassis 1-17 is a rectangular frame, and two pairs of wheels are connected to the bottom surface of the chassis 1-17 through rolling shafts. The wheels match the track so that the rail injection vehicle can run on the track without hitting the bolts on the track. The drive motor is arranged in the rectangular frame, and the drive rear motor is connected to one of the rolling shafts.

[0061] In one embodiment, referring to Figure 1-2 The oil injection device includes an oil filling barrel 1-15 and an oil filling valve 1-1. The oil filling barrel 1-15 and the oil filling nozzle 1-2 are connected by a pipeline. The oil filling valve 1-1 is arranged on the pipeline. A cavity for storing grease is arranged in the oil filling valve 1-1.

[0062] Among them, the injection valve 1-1 can control the opening and closing of the oil in the oil filling barrel 1-15 when it flows to the injection nozzle 1-2, as well as the adjustment of the oil flow rate. In this embodiment, the injection valve 1-1 directly controls the oil output through the cavity. For example, the capacity of the cavity can be adjusted according to the scale. When quantitative oil injection is required, the cavity scale is adjusted to a specified position; in other embodiments, the injection valve 1-1 can adjust the oil output by controlling the time; Figure 4 and Figure 5They are respectively non-quantitative valve and quantitative valve, both of which can be applied in this application.

[0063] In this embodiment, the cavity is set to control the oil output, so that the rail spraying vehicle can use the grease more accurately and reduce the waste of grease.

[0064] In one embodiment, referring to Figure 4-5 The oil injection device also includes an air compressor 1-12, a pneumatic pump and a pressure reducing valve 1-16. The pneumatic pump is arranged on the pipeline connecting the oil filling barrel 1-15 and the oil filling valve 1-1. The pressure reducing valve 1-16 is arranged on the pipeline connecting the pneumatic pump and the oil filling barrel 1-15. The air compressor 1-12 provides an air source for the pneumatic pump.

[0065] Among them, the connection relationship is oil filling barrel 1-15, pressure reducing valve 1-16, pneumatic pump, oil filling valve 1-1 and oil injection nozzle 1-2 in sequence.

[0066] Specifically, when the rail spraying vehicle starts operating, the air compressor 1-12 works to provide an air source for the pneumatic pump, the pneumatic pump extracts the grease in the oil filling barrel 1-15 and transports it through the oil pipe, passes through the pressure reducing valve 1-16 to the injection valve 1-1, and the oil is atomized and sprayed out from the injection nozzle 1-2 through the compressed gas from the oil filling valve 1-1; during the injection interval, the grease transported through the oil filling barrel 1-15 in the cavity fills the cavity, and when it arrives at the designated spraying location, the oil inlet of the injection valve 1-1 is closed, and the injection port is opened, and the grease enters the injection nozzle 1-2 through the oil injection port and is mixed with the high-pressure gas and atomized and sprayed out.

[0067] In this embodiment, the operation of the rail fuel injection vehicle is made more convenient by providing a pneumatic pump, a pressure reducing valve 1-16, etc.

[0068] In one embodiment, referring to Figure 3 The injector adjustment module includes an injector transverse movement mechanism 1-5 and an injector lifting mechanism 1-4. The injector transverse movement mechanism 1-5 is fixed on the walking device 1-10. The injector lifting mechanism 1-4 is connected to the injector transverse movement mechanism. The injector 1-2 is connected to the injector lifting mechanism 1-4.

[0069] Among them, the fuel injector transverse movement mechanism 1-5 is used to control the left and right movement of the fuel injector 1-2, and the fuel injector lifting mechanism 1-4 is used to control the up and down movement of the fuel injector 1-2.

[0070] In one embodiment, referring to Figure 1-2 The regulating device also includes an regulating motor 1-6, and the regulating motor 1-6 is connected to the fuel injector regulating module.

[0071] Wherein, the regulating motor 1-6 is connected to the control device, and the regulating motor 1-6 can control the injector lateral movement mechanism 1-5 and the injector lifting mechanism 1-4.

[0072] In one embodiment, referring to Figure 1-2 The fuel injection device includes two groups of the fuel injectors 1-2, each group is provided with two fuel injectors 1-2, and each fuel injector 1-2 corresponds to a fuel injector adjustment module. The detection device includes four laser distance sensors 1-18 and four inductive sensors 1-7. The laser distance sensors 1-18 are symmetrically arranged on the walking device 1-10, and the inductive sensors 1-7 are symmetrically arranged on the walking device 1-10.

[0073] As is well known, a track comprises two steel rails, each of which is fixed to the ground by bolts and sleepers on both sides, and the gauge between the rails is fixed.

[0074] Specifically, the rail fuel injection vehicle travels on a track, which includes four bolted routes parallel to the travel direction, wherein each route includes a laser distance sensor 1-18, an inductive sensor 1-7 and a fuel injection nozzle 1-2.

[0075] In one embodiment, referring to Figure 1-2 , the regulating device also includes a travel switch 1-9, and the travel switch 1-9 is connected to the inductive sensor 1-7.

[0076] The travel switches 1-9 are used to directly contact and detect an object and determine whether its height exceeds a limit, which is a physical safety mechanism.

[0077] Specifically, when there are higher debris on the track, the inductive sensor 1-7 swings through the travel switch 1-9, and the travel switch 1-9 is closed and energized. If the laser distance sensor 1-18 fails to determine the height of the raised position due to failure or detection error, the higher debris will activate the travel switch 1-9 in a direct contact manner and send out an electrical signal to lift the injector 1-2 as a whole to prevent the injector 1-2 from colliding with the raised point.

[0078] In one embodiment, the rail fuel injection vehicle includes a running device 1-10, a fuel injection device, an adjustment device, a detection device, a control device, a lighting device and a power device. The running device 1-10 includes a chassis 1-17, wheels and a drive motor. The chassis 1-17 is a rectangular frame, and two pairs of wheels are connected to the bottom surface of the chassis 1-17 through rolling shafts.

[0080] In a second aspect, the present invention provides an intelligent rail injection method, referring to the figure, the rail injection method comprises:

[0081] S110, when the rail fuel injection vehicle moves forward on the rail, obtaining and recording the height of an object in front of the rail fuel injection vehicle detected by the laser distance sensor, and adjusting the height of the inductive sensor and the fuel injection nozzle according to the height of the object, wherein the rail fuel injection vehicle is the rail fuel injection vehicle described in any one of the first aspect;

[0082] Among them, the objects detected by the laser distance sensor 1-18 include foreign objects and bolts on the track. The height is adjusted this time to avoid the objects. The height of the inductive sensor 1-7 should be just larger than the object to facilitate the inductive sensor 1-7 to detect whether the object is a bolt, and there is no other requirement for the height of the injector 1-2.

[0083] S120, when the inductive sensor detects that the object is a bolt, the height of the fuel injector is adjusted according to the recorded height of the bolt, and the fuel injector sprays fuel to the bolt.

[0084] Among them, the height of the injector 1-2 adjusted this time should be at a fixed distance from the top of the bolt to facilitate the injector 1-2 to spray oil on the bolts on the track, and the distance is determined according to the oil quality; at the same time, according to the embodiment of the first aspect, it can be known that the laser distance sensor 1-18, the inductive sensor 1-7 and the injector 1-2 will pass by the bolts on the track in turn, and these three cooperate to enable the track injection vehicle to spray oil without stopping.

[0085] It should be noted that when the viscosity of the oil used is high, the injection response time is long, and the actual injection opening time needs to increase the advance amount. The specific advance time is related to the viscosity of the oil used, the vehicle speed, and the height of the injector 1-2. The time required for the oil flow to reach the specified flow from speed 0 is t1, and the time for the oil to reach the target surface from the injector 1-2 is t2. Since the designed injection device has an adjustment function, the distance between the injector 1-2 and the target surface is fixed, that is, t2 is fixed. Since the injector 1-2 has a certain inclination angle θ with the vertical, the advance amount required for the height is t h :

[0086]

[0087] The time required for the oil flow to reach the specified flow from speed 0 is t1, which is related to the oil viscosity, nozzle structure, etc. The total lead time is: t 总 =t h +t1

[0088] In this embodiment, by designing the inductive sensor 1-7 and the laser distance sensor 1-18 to jointly monitor the bolt posture, it is possible to effectively avoid the accidental injection of foreign objects, improve the efficiency of the rail fuel injection vehicle, and reduce the impact of the environment on the operation of the rail fuel injection vehicle.

[0091] Specifically, the camera obtains the image of the bolt after oil injection and transmits it to the control device, which performs effect analysis on the image.

[0092] S140, when the injection effect does not meet the preset effect, the location is recorded, and when the injection of the interval section is completed, the rail injection vehicle performs rework injection according to the location.

[0093] During rework, the position of the fuel injector 1-2 will be adjusted according to the fuel injection effect.

[0094] In this embodiment, cameras 1-3 are set to capture the effect after oil injection, select bolts with poor oil injection effect and rework them, and at the same time, the oil injection time and posture are corrected and adjusted in real time to realize the intelligent oil injection process.

[0095] In one embodiment, referring to Figure 8-9 The step of analyzing the fuel injection effect of the image comprises:

[0096] S131, acquiring the degree of displacement of the oil in a direction parallel to the track and a degree of displacement in a direction perpendicular to the track according to the image;

[0097] Specifically, Fig. 9 As shown in the figure, the coordinates are established on the injection target bolt, and the displacement degree of the oil in the parallel direction of the track is taken as a according to the reference injection projection profile and the actual injection projection profile. x , the vertical offset is a y .

[0098] S132: When the offset degree in the parallel direction or the offset degree in the vertical direction exceeds a preset value, the oil injection effect does not meet the expected effect.

[0099] Specifically, Fig. 9 As shown, the degree of deviation of the oil in the direction parallel to the rail is detected. x And the degree of displacement of the oil in the vertical direction of the rail a y , if a x or a y If it exceeds the preset value, the position is recorded and the rail fuel injection vehicle returns to this point after completing the work of the section, and adjusts the movement of the fuel injection nozzle 1-2 in the parallel direction of the track -a x , vertical movement -ay , and then spray oil on the bolt at that point.
