Description

Technical Field

[0001] This invention relates to the field of railway track maintenance equipment technology, specifically to a railway oiling machine. Background Technology

[0002] Concrete sleeper anchor bolts and fasteners on railway tracks are key components for securing rails and ensuring their stability, directly impacting track stability. Because these anchor bolts and fasteners are installed outdoors, they are highly susceptible to corrosion and failure due to wind, sun, and rain, affecting equipment quality and posing safety hazards. Corrosion of anchor bolts and fasteners is a serious equipment defect in railway tracks. Prolonged failure can lead to insufficient clamping force between the fasteners and the rails, creating "false torque," causing uncontrolled rail expansion and contraction, inaccurate rail temperature locking, and in severe cases, rail breakage, track scrambling, and other accidents. Therefore, track maintenance departments attach great importance to the lubrication and maintenance of anchor bolts, listing it as an essential part of track maintenance. Regulations stipulate that anchor bolts and fasteners must be lubricated annually after summer maintenance or in the spring.

[0003] Currently, existing oiling devices require a process of moving to a stop, which can lead to inaccurate oiling positions. Due to the different viscosities of machine oil and grease, grease can adhere to the oil cylinder, so the equipment cannot simultaneously adapt to the application of both machine oil and grease. The fixed position of the oiling components cannot meet the oiling requirements of rails of different specifications. The lack of monitoring methods for the use of the equipment on the track can cause the equipment to become stuck on the railway, requiring enhanced monitoring. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a railway oiling machine. By connecting an air supply line to the oil supply line, under the control of the electronic control system, the oil spraying process can be pressurized. The air pressure draws the grease out of the oil storage tank, avoiding the solidification of grease residue in the pipeline. Thus, the oiling machine can be used for both grease and machine oil. It has a fast oiling speed and good adhesion. Moreover, the oiling machine moves automatically under the control of the electronic control system, without dripping, pollution and waste. The dosage is controllable, saving material costs.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0006] A railway oiling machine includes a frame, a traveling assembly, an oil spraying assembly, and an electrical control system. The traveling assembly is located at the bottom of the frame, the oil spraying assembly is located on the frame, the oil spraying assembly is connected to an oil supply line and an air supply line, an air pump is provided on the air supply line, and the electrical control system is electrically connected to the traveling assembly, the oil spraying assembly, the oil supply line, and the air supply line.

[0007] According to the railway oiling machine of the present invention, the traveling component is first directly mounted on the rail. The traveling component is driven to roll along the rail by the electronic control system, thereby driving the entire oiling machine to move along the rail. When it moves to the sleeper bolt, the electronic control system controls the traveling component to stop and controls the oil spraying component to spray oil for lubrication. By connecting a pressurized air circuit to the traditional oil spraying pipeline, the oil spraying process can be pressurized, avoiding the solidification of grease residue in the pipeline. This allows the oiling machine to be used for both machine oil and grease. Under the control of the electronic control system, the oiling speed can be fast, the operation process can be precisely controlled, the adhesion can be good, there is no dripping, pollution and waste, the dosage can be controlled, and material costs can be saved.

[0008] The above technical solution can be further improved as described below.

[0009] In a preferred embodiment of the railway oiling machine according to the present invention, the railway oiling machine further includes a speed measuring device and a position measuring device respectively mounted on the frame. The speed measuring device and the position measuring device respectively collect travel speed data and position data and transmit them to the electronic control system. The electronic control system controls the opening and closing of the oil supply line, the air supply line and the oil injection assembly according to the travel speed data and the position data.

[0010] According to the railway oiling mechanism of the present invention, through the automatic control coordination between the speed measuring device, the position measuring device and the electrical control system, the traveling speed data and position data are collected, and the adaptive control algorithm is used to complete the calculation of speed variables and nozzle switch lag constant parameters, and calculate the opening time of the solenoid valve on the oil supply line, so that the entire oiling machine can stop more accurately at the bolt on the rail, and the oil spray is accurately positioned on the bolt head, thereby avoiding inaccurate oil spraying position of the oil spraying component.

[0011] Specifically, in a preferred embodiment, the speed measuring device includes a speed sensor disposed on the walking assembly, and the position measuring device includes a position sensor disposed on the frame.

[0012] The aforementioned speed and position sensors are easy to install and their data measurement and transmission are accurate and reliable.

[0013] Specifically, in a preferred embodiment, the fuel injection assembly includes an adjustment guide rail, a first support arm, an adjustment component, a contact foot, a fuel injection module, and a position switch. The first support arm is arranged opposite to both ends of the adjustment guide rail and is rotatably connected to the adjustment guide rail. The adjustment component is arranged opposite to both sides of the bottom of the adjustment guide rail and extends toward the first support arm. The contact foot is arranged opposite to the inner side of the first support arm. The fuel injection module is arranged opposite to the bottom end of the first support arm and the injection direction is toward the inner side. The position switch is arranged at the bottom of the first support arm and is electrically connected to the electronic control system.

[0014] Specifically, the adjusting guide rail in the above-mentioned oil spraying assembly can cooperate with the adjusting assembly to achieve vertical position adjustment. The position switch is triggered when passing the bolt or fastener to be oiled, giving an oil spraying position signal. The adjusting component is used to adjust the rotation angle of the oil spraying module, and the contact foot is used to contact the concrete sleeper vertical bolt and fastener equipment. During operation, the contact foot of the concrete sleeper vertical bolt and fastener equipment contacts and slides over the vertical bolt and fastener to be oiled. If the bolt or fastener is irregular, the contact foot automatically drives the support arm of the adjusting oil spraying module to rotate around the optical axis, thereby adjusting the oil spraying module to align with the irregular vertical bolt and fastener.

[0015] Specifically, in a preferred embodiment, the adjusting component includes a positioning bolt.

[0016] Using positioning bolts as adjustment components, the structure is simple and compact, easy to arrange and operate, and low in cost.

[0017] Specifically, in a preferred embodiment, the support arm is connected to the adjusting guide rail via an optical axis and a bushing sleeved on the optical axis.

[0018] The above-mentioned rotating connection structure is simple, compact, easy to operate, and stable and reliable in operation.

[0019] Furthermore, in a preferred embodiment, the support arms are interconnected by elastic connecting members.

[0020] Springs and other elastic connecting components are used to adjust the rotational force of the support arm, ensuring that the entire fuel injection assembly operates stably and reliably.

[0021] Furthermore, in a preferred embodiment, the fuel injection assembly is arranged on the vehicle frame via an adjustment assembly, wherein the adjustment assembly includes a second support arm, a support rod, and a locking handle. The support rod is arranged on the vehicle frame and connected to the second support arm. The locking handle is connected to the first and second support arms. The support rod is provided with a rack structure, and the locking tongue at the front end of the locking handle can engage or disengage from the tooth groove of the rack structure. The adjustment guide is sleeved on the support rod.

[0022] Specifically, the handle and the oil spraying assembly are connected together. The support rod has a rack and pinion structure. The locking tongue at the front of the locking handle enters the tooth groove of the support rod to lock it. When the locking handle is released, the locking tongue at the front of it disengages from the tooth groove and can move up and down to adjust the height of the oil spraying assembly, thereby effectively improving the applicability of the entire oiling machine.

[0023] Specifically, in a preferred embodiment, the walking assembly includes a motor, a reducer, a pulley, and a walking wheel, wherein the motor drives the pulley through the reducer, thereby causing the walking wheel to move.

[0024] The walking component with the above-described structure is simple in structure, easy to arrange, install and control, and its walking process is stable and reliable.

[0025] Furthermore, in a preferred embodiment, the traveling components are symmetrically arranged on both sides of the bottom of the frame along the direction parallel to the extension of the rails, and the traveling wheels symmetrically arranged on both sides along the direction parallel to the extension of the rails are connected to each other by a drive shaft.

[0026] The aforementioned walking assembly structure can further improve the structural stability and reliability of the entire oiling machine and ensure the stability and reliability of the working process.

[0027] Furthermore, in a preferred embodiment, the railway oiling machine is also equipped with a positioning device electrically connected to the electrical control system.

[0028] Specifically, due to the lack of monitoring methods for equipment use on the tracks, the equipment may become stuck on the railway. It is necessary to strengthen monitoring. By setting up positioning devices and adding geographic location positioning functions, the location of the oiling device can be monitored in real time, providing the equipment location and status, and providing alarm functions to prevent the equipment from becoming stuck on the tracks and affecting safe operation.

[0029] Compared with the prior art, the advantages of this invention are: by connecting a pressurized air circuit to the traditional oil injection pipeline, the oil injection process can be pressurized, avoiding the solidification of grease residue in the pipeline. This allows the oiling machine to be used for both engine oil and grease. Under the control of the electronic control system, it can achieve fast oiling speed, precise control of the operation process, good adhesion, no dripping, pollution and waste, controllable dosage, and save material costs.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection of the present invention.

[0038] Figure 1 The schematic diagram illustrates the frame control principle of the railway oiling machine 100 according to an embodiment of the present invention. Figure 2 The schematic diagram shows the front view of a railway oiling machine 100 according to an embodiment of the present invention. Figure 3 The schematic diagram shows a top view of the fuel injection assembly 30 in an embodiment of the present invention. Figure 4 The schematic diagram shows the side view of the fuel injection assembly 30 in an embodiment of the present invention. Figure 5 The schematic diagram shows the side view of a railway oiling machine 100 according to an embodiment of the present invention.

[0039] like Figures 1 to 5 As shown, the railway oiling machine 100 of this embodiment includes a frame 10, a traveling assembly 20, an oil spraying assembly 30, and an electronic control system 40. The traveling assembly 20 is disposed at the bottom of the frame 10, the oil spraying assembly 30 is disposed on the frame 10, the oil spraying assembly 30 is connected to an oil supply line 50 and an air supply line 60, and an air pump 62 is provided on the air supply line 60. The electronic control system 40 is electrically connected to the traveling assembly 20, the oil spraying assembly 30, the oil supply line 50, and the air supply line 60.

[0040] According to an embodiment of the railway oiling machine of the present invention, the traveling component is first directly mounted on the railway rail. The traveling component is driven to roll along the rail by an electronic control system, thereby moving the entire oiling machine along the rail. When it reaches the sleeper bolts, the electronic control system stops the traveling component and simultaneously controls the oil spraying component to spray oil for lubrication. By connecting a pressurized air circuit to the traditional oil spraying pipeline, the oil spraying process can be pressurized, preventing grease residue and solidification within the pipeline. This allows the oiling machine to be used with both machine oil and grease. Under the control of the electronic control system, it achieves fast oiling speed, precise control of the operation process, good adhesion, no dripping, pollution, or waste, controllable dosage, and savings in material costs. The machine oil and grease are pressurized and extruded by a compression pump, and then purged through the air circuit, resulting in uniform spraying and excellent coating effect.

[0041] like Figure 1As shown, specifically in this embodiment, the electronic control system uses a rechargeable high-efficiency lithium battery for power. Control is achieved using microcontroller technology. By collecting data such as position sensor signals and travel speed, an adaptive algorithm is used to calculate the timing of opening the solenoid valve, ensuring accurate oil injection onto the bolt head. Uniform travel speed allows for accurate calculation of lead time; the adjustable oil applicator adapts to the bolt's lateral position and vertical height; a unique air-purified oil delivery pipe prevents leakage; and the plunger pump pressurization mechanism is adaptable to engine oil, grease, and different oil qualities.

[0042] Lead time calculation:

[0043] L = ∨ * ΔT + l∨ --- Velocity ΔT --- Lead time l --- Fixed lead

[0044] To meet the needs of work efficiency and separate operations, the system is designed in a modular fashion according to function. The oiling module uses compressed air to compress and spray out the oil, emptying the oil chamber and preventing dripping. The switch uses a mechanical touch mechanism, which is simple and effective.

[0045] like Figure 2 As shown, specifically, in this embodiment, the oil supply circuit 50 includes an oil tank 51, an oil pump 52 located at the outlet of the oil tank 51, an oil pipe 53 connected to the oil pump 52 and the injection assembly 30 respectively, and an oil circuit solenoid control valve 54 located on the oil pipe 53 near the injection assembly 30. The oil pump 52 and the oil circuit solenoid control valve 54 are electrically connected to the electronic control system 40. Figure 2 As shown in Figure 6, specifically in this embodiment, the air supply path 60 includes an air tank 61, an air pump 62 located at the outlet of the air tank 61, an air pipe 63 connected to the air tank 61 and the fuel injection assembly 30 respectively, and a fuel injection solenoid valve 64 located on the air pipe 63 near the fuel injection assembly 30. The air pump 62 and the air valve 64 are electrically connected to the electronic control system 40. Specifically, in this embodiment, the oil pump draws grease from the oil tank and pressurizes it, then delivers it to the fuel injection assembly through the oil pipe and the fuel injection solenoid valve. Under the purging of compressed air, it is sprayed onto the fastener bolts, achieving the effect of coating them with grease. The air pump pressurizes air to the air tank, delivers it to the fuel injection assembly through the air pipe and the fuel injection solenoid valve, and purges the grease in the fuel injection assembly onto the fastener bolts to complete the grease spraying.

[0046] Specifically, in this embodiment, the traveling assembly 20 includes a motor, a reducer, a pulley, and traveling wheels. The motor drives the pulley through the reducer, thereby moving the traveling wheels. This type of traveling assembly is simple in structure, easy to arrange, install, and control, and provides stable and reliable movement. Furthermore, in this embodiment, the traveling assembly 20 is symmetrically arranged on both sides of the bottom of the frame 10 along the direction parallel to the rail extension, and the traveling wheels symmetrically arranged on both sides are interconnected via a drive shaft. This type of traveling assembly further improves the structural stability and reliability of the entire oiling machine and ensures stable and reliable operation. Specifically, in this embodiment, the electronic control system 40 controls a servo motor, which drives the pulley through the reducer, thereby moving the traveling wheels forward or backward.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the railway oiling machine 100 further includes a speed measuring device 70 and a position measuring device 80 respectively installed on the frame 10. The speed measuring device 70 and the position measuring device 80 collect travel speed data and position data respectively and transmit them to the electronic control system 40. The electronic control system 40 controls the opening and closing of the oil supply line, the air supply line and the oil injection assembly according to the travel speed data and position data.

[0048] According to an embodiment of the present invention, the railway oiling mechanism, through automatic control coordination between the speed measuring device, the position measuring device, and the electronic control system, collects travel speed data and position data. An adaptive control algorithm is used to calculate the speed variable and the nozzle switch hysteresis constant parameters, and to calculate the opening time of the solenoid valve on the oil supply line. This allows the entire oiling machine to stop more accurately at the bolts on the rail, ensuring precise oil spraying onto the bolt heads, thereby preventing inaccurate oil spraying positions of the oil spraying assembly. Specifically, in this embodiment, the speed measuring device 70 includes a speed sensor mounted on the traveling assembly, and the position measuring device 80 includes a position sensor mounted on the frame. These speed and position sensors are easy to install and provide accurate and reliable data measurement and transmission.

[0049] like Figure 3 and Figure 4As shown, specifically in this embodiment, the oil spraying assembly 30 includes an adjusting guide rail 31, a first support arm 34, a positioning bolt 35, a spring 36, a contact foot 37, an oil spraying module 38, and a position switch 39. The first support arm 34 is arranged opposite to both ends of the adjusting guide rail 21 and is rotatably connected to the adjusting guide rail 31 via an optical shaft 32 and a bushing 33 sleeved on the optical shaft 33. The positioning bolt 35 is arranged opposite to both sides of the bottom of the vertical strip adjusting guide rail 31, extending towards the first support arm 34. The spring 36 is arranged below the positioning bolt 35, with both ends connected to the inner side of the first support arm 34. The contact foot 37 is located below the spring 36 and is arranged opposite to the inner side of the first support arm 34. The oil spraying module 38 is arranged opposite to the bottom end of the first support arm 34, with the spray direction facing inward. The positioning bolt 35 is used to adjust the rotation angle of the oil spraying module 38, the spring 36 is used to adjust the rotation force of the first support arm 34, and the contact foot 37 is used to contact the concrete sleeper vertical bolts and fastening equipment. Position switch 39 is located at the bottom of the first support arm 34 and is electrically connected to the electrical control system 40. The position switch is triggered when it passes the bolt or fastener to be oiled, giving an oil spraying position signal. During operation, the contact foot 37 of the equipment that touches the concrete sleeper upright bolt and fastener contacts and slides over the upright bolt or fastener to be oiled. If the bolt or fastener is irregular, the contact foot 37 automatically drives the support arm 34 of the oil spraying module 38 to rotate around the optical axis 33, thereby adjusting the oil spraying module 38 to align with the irregular upright bolt or fastener.

[0050] like Figure 4 As shown, further, in this embodiment, the oil spraying assembly 30 is arranged on the frame 10 via an adjustment assembly 90. The adjustment assembly 90 includes a support rod 91, a locking handle 92, and a second support arm 93. The support rod 91 is arranged on the frame 10 and connected to the second support arm 93. The locking handle 92 is connected to the first support arm 34 and the second support arm 93. The support rod 91 is provided with a rack structure 94. The locking tongue at the front end of the locking handle 92 can engage or disengage from the toothed groove of the rack structure 94. The adjustment guide rail 31 is sleeved on the support rod 91. Specifically, the handle and the oil spraying assembly are connected together. The support rod has a rack structure, and the locking tongue at the front end of the locking handle probes into the toothed groove of the support rod, providing a locking function. By releasing or pressing the locking handle, the entire oil spraying assembly can be raised or lowered to adjust its height, adapting to the distance between the oil nozzle and the bolts and fasteners to be sprayed, thus achieving suitable operation and effectively improving the applicability of the entire oiling machine.

[0051] Furthermore, in this embodiment, the railway oiling machine 100 is also equipped with a positioning device electrically connected to the electrical control system 40. Specifically, due to the lack of monitoring methods for equipment use on the railway, the equipment may become stranded on the tracks. Therefore, enhanced monitoring is necessary. By setting up a positioning device and adding a geographic location positioning function, the location of the oiling device can be monitored in real time, providing the equipment's location and status, and providing an alarm function to prevent the equipment from becoming stranded on the tracks and affecting safe operation. Specifically, in this embodiment, a Beidou positioning module is installed on the railway oiling machine 100 to collect satellite positioning information in real time and send it to the data center and mobile APP. Before operation, an application must be submitted to use the oiling machine, and the usage time and location must be set. During operation, the data center and mobile APP monitor the usage time and location of the oiling machine in real time. When the positioning module sends a message indicating that the usage location or usage time exceeds the limit, an alarm signal is promptly issued to remind the staff to evacuate in time, preventing the equipment from becoming stranded on the railway and affecting safety.

[0052] As can be seen from the above embodiments, the railway oiling machine of the present invention, by connecting a pressurized air circuit to the traditional oil spraying pipeline, can pressurize the oil spraying process, avoid the solidification of grease residue in the pipeline, and make the oiling machine suitable for the use of both machine oil and grease. Under the control of the electronic control system, it can achieve fast oiling speed, precise control of the operation process, good adhesion, no dripping, pollution and waste, controllable dosage, saving material costs, and good spraying effect.

[0053] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
