Description

Technical Field

[0001] This utility model relates to the technical field of oiling track fasteners, specifically to an oiling device for track fasteners. Background Technology

[0002] Track fasteners are the main components providing elasticity in railway track systems, and railway sleeper bolts are an important part of railway track fasteners. As the line operates for a long time, due to long-term exposure to the atmosphere and cyclical climate changes such as wind, rain, frost, and snow burial, the fastener bolts on the track sleepers will experience varying degrees of oxidation and corrosion. Some bolts will develop necking. The cumulative corrosion from these factors affects the torque of the fasteners. Bolts that have not been moved for a long time will develop false torque or the elastic clips will not be properly tightened, which seriously affects the safety of train operation. Therefore, the fastener system must be periodically lubricated and periodically oiled every year.

[0003] Early anti-corrosion maintenance of fastener bolts involved manual oiling, which was costly, inefficient, and labor-intensive. Currently, auxiliary oiling devices are used, such as the one disclosed in Chinese Patent No. ZL202022183463.X, which describes an oiling device for railway track fasteners. This device includes a mounting block with a push rod fixedly mounted on its surface. A connecting rod is fixedly connected to the inner side of the mounting block, and a first bearing is mounted on the surface of the connecting rod. A pulley is mounted on the surface of the first bearing, and mounting plates are fixedly connected to both ends of the connecting rod. A second bearing is mounted on the surface of the mounting plate, and an application roller is fixedly connected to the inner side of the second bearing. When using this device, the pulley... This device, mounted on the rail surface and pushed along the rail, lifts a push rod when it encounters a fastener, causing the mounting plate and coating roller to press downwards against the fastener surface. The coating roller rotates along the fastener surface, applying oil-absorbing cotton to protect the fastener. This facilitates oiling the fasteners. However, this oiling device can only oil one side of the track. Since railway tracks are typically double-rail, this means that when using this device to oil track fasteners, the same section of track requires two separate applications, resulting in low oiling efficiency. Chinese Patent No. ZL201921075469.6 discloses an oiling trolley for railway fasteners, including a fixed frame. The system consists of a frame and track wheels. Two oil tanks are fixed to the fixed frame, each with an oiling assembly below it. The oiling assembly includes a U-shaped rod at the bottom of the fixed frame and oiling terminals at both ends of the U-shaped rod. The lower surface of each oiling terminal has an oiling base with a receiving groove. An oil outlet pipe is located on the oil tank, extending to the top of the oiling terminal and sealed with a sealing plate. An oil suction assembly is installed between the oil tank and the oil outlet pipe. Multiple branch pipes are inserted into the oil outlet pipe, connecting to the oil drain holes of the oiling terminal. An oil valve is also installed on the oil outlet pipe. A drive assembly is installed on the U-shaped rod to engage the fasteners on both sides of each track. The oiling process is relatively easy to operate; one person can push the trolley to apply oil to the fasteners on both sides of the railway, saving a lot of manpower. However, the device still requires manual operation to push and control the oiling position, making it inconvenient to use. In addition, the device is large and heavy, and it is time-consuming and laborious to move it onto the track before or after oiling. Furthermore, the timing of oiling the fasteners on both sides of each track needs to be controlled individually. When the track curves, the timing of oiling the fasteners on both sides of the two tracks may be inconsistent, requiring manual operation of the push rod one by one, resulting in low oiling efficiency and high labor intensity. Summary of the Invention

[0004] The technical problem to be solved by this utility model is how to improve the efficiency of applying oil to rail fasteners and how to reduce the labor intensity of operators. The purpose of this utility model is to provide a self-propelled rail fastener oiling device that automatically senses rail fasteners through sensors and automatically sprays anti-rust oil from multiple directions.

[0005] The technical solution adopted by this utility model is as follows: a track fastener oiling device, including an oiling frame and a power frame. The tail end of the oiling frame is detachably connected to the front end of the power frame. Four first track wheels are distributed at the four corners of the bottom of the oiling frame. The first track wheels on the left and right sides are symmetrically arranged along the virtual central axis of the oiling frame and are located on two tracks. The first track wheels at the front and rear ends are fixedly connected by two first axles perpendicular to the tracks. Extension frames are provided on both the left and right sides of the oiling frame, and multiple proximity sensors are provided at the bottom of each extension frame. The oiling frame is equipped with an oiling assembly, which includes multiple oil nozzles. The multiple oil nozzles are symmetrically distributed on the extension frames on both sides of the oiling frame. The oiling frame is also equipped with two pumps symmetrically distributed along the middle of the oiling frame. The bottom of the power frame has four second track wheels distributed at the four corners. The second track wheels on the left and right sides are symmetrically arranged along the virtual central axis of the power frame and are located at the top of the two tracks. The second track wheels at the front and rear ends are fixedly connected by two second shafts perpendicular to the tracks. The power frame is equipped with a power assembly.

[0006] The rail fastener oiling device provided by this utility model can achieve the following beneficial effects:

[0007] (1) Extension racks are provided at both ends of the oiling rack, and each extension rack is equipped with multiple oil spray nozzles, which can simultaneously spray anti-rust oil on both sides of the track. It is convenient to use, has high oiling efficiency, simplifies the maintenance process of track fasteners, shortens the time required for oiling track fasteners, and also reduces the time required to transport the oiling device.

[0008] (2) The oiling rack used for oiling can be detachably connected to the self-propelled power rack, which is convenient for separate handling and installation on the track, saving effort and making disassembly and assembly convenient.

[0009] (3) Using a pump as the power source for oiling ensures stable pressure and flow rate. The oiling area and amount will not be reduced due to insufficient capacity of the rust-preventive oil, which would lead to a decrease in the flow rate and velocity of the rust-preventive oil. This ensures the quality and effect of the rust-preventive oil spraying.

[0010] Preferably, the oiling rack is also equipped with an oil tank mounting bracket, the oil tank mounting bracket is equipped with a clamp, and the oil tank is detachably installed in the clamp. The bottom of the oil tank is equipped with a T-shaped oil outlet, and the openings at both ends of the T-shaped oil outlet are respectively connected to two pumps. Each pump is connected to multiple oil nozzles through an oil injection pipe.

[0011] By detachably mounting the oil tank on the oil tank mounting frame, the weight of the device can be reduced during installation before oiling and disassembly after oiling. By connecting the T-shaped oil outlet at the bottom of the oil tank to two pumps, the two pumps can simultaneously pump rust-preventive oil to the inner and outer sides of each track. Finally, the oil is sprayed onto the track fasteners on the inner and outer sides of the track through multiple spray nozzles. The spraying work of the two tracks does not affect each other.

[0012] Preferably, a solenoid valve is installed on the fuel injection pipe between the pump and the fuel injector.

[0013] The solenoid valve is used as the switch for oil injection. The solenoid valve opens when oil injection is needed and closes when oil injection is not needed, thus avoiding waste and pollution of rust-preventive oil.

[0014] Preferably, there are four nozzles on each side of the oiling rack. The four nozzles are symmetrically distributed in pairs along the track and are tilted back and forth, so that the virtual extension lines of the nozzles on the front and back sides intersect at the top of the fasteners on both sides of the track.

[0015] By aligning the four spray nozzles on each side of the oiling rack with the front and rear ends of the top of the fasteners on both sides of the track, the oiling rack moves forward so that each fastener can be sprayed with anti-rust oil from the front and rear top at the same time, ensuring even spraying and reducing dead corners.

[0016] Preferably, at least two proximity sensors are provided at the bottom of the extension frame on each side of the oiling rack, with the bottom of the proximity sensors aligned with the top of the fasteners on both sides of the track.

[0017] The opening and closing of the solenoid valve is controlled by a proximity sensor. When the proximity sensor detects the track fastener, it generates an electrical signal to control the solenoid valve to open quickly, allowing the rust-preventive oil to be sprayed onto the track fastener under the action of the pump. As the oiling frame and the power frame move, when the proximity sensor detects that the track fastener has left the track fastener, the proximity sensor controls the solenoid valve to close the circuit, and the oil nozzle stops spraying the rust-preventive oil, reducing the waste and pollution of the rust-preventive oil. By using at least two proximity sensors to simultaneously detect the track fasteners on both the inner and outer sides of a single track, the detection accuracy is further improved, and it is prevented that debris on both sides of the track will affect the detection effect of the proximity sensors.

[0018] Preferably, the top of the oil tank is provided with a dust cover.

[0019] By using a dust cover to prevent external debris from entering the oil tank, and at the same time to keep the air pressure inside and outside the oil tank consistent, the pump can ensure that the pressure inside and outside the oil tank remains consistent when it draws out the anti-rust oil from the bottom of the tank, thereby keeping the flow rate of the pump stable.

[0020] Preferably, a magnetic level gauge is provided on the side wall of the oil tank.

[0021] The magnetic level gauge allows for a clear and intuitive understanding of the remaining amount of rust-preventive oil in the tank, enabling operators to replenish the oil in a timely manner and thus increasing the completion rate of track oiling.

[0022] Preferably, the power frame is equipped with a protective frame and a seat.

[0023] The seat allows the operator to sit comfortably on the power frame, while the safety frame helps protect the operator.

[0024] Preferably, safety doors are hinged to both sides of the protective frame.

[0025] Safety doors protect operators from falling off the seats.

[0026] Preferably, the oiling rack has a first connecting hole at its tail end, and the power frame has a second connecting hole at its front end that is adapted to the first connecting hole on the oiling rack. The protective frame also has a pin bracket with a pin detachably inserted into it. The pin is used to simultaneously insert into the first connecting hole and the second connecting hole after the first connecting hole and the second connecting hole are aligned, so that the bracket and the power frame are connected to each other.

[0027] The first connecting hole and the second connecting hole, along with the pin, facilitate the connection between the oiling rack and the power frame. After placing both the oiling rack and the power frame on the track, position the oiling rack at the front end of the power frame, ensuring that the first connecting hole at the rear of the power frame and the second connecting hole at the front end of the power frame are close together and overlap. Finally, secure them with the pin, thus connecting the oiling rack and the power frame during use. When disassembly is required after the oiling operation, pull out the pin and place it on the pin holder on the protective frame to prevent loss. Then, the oiling rack and the power frame can be lifted off the track in sequence. By detachably connecting the oiling rack and the power frame, the intensity of lifting the device onto or off the track is reduced, thus reducing the labor intensity of the operators.

[0028] Preferably, the power assembly includes a geared motor and a transmission assembly. A transmission assembly mounting bracket is fixedly connected to the power frame. Both the geared motor and the transmission assembly mounting bracket are fixedly connected to the power frame. The transmission assembly is mounted on the transmission assembly mounting bracket. The geared motor is driven by the transmission assembly, and the transmission assembly is driven by the second shaft.

[0029] The second shaft is driven to rotate by a geared motor and transmission components, which provides power for the self-movement of the power frame. The power frame pushes the oiling frame forward, realizing the device's self-movement and automatic oiling, reducing the difficulty of operation, labor intensity and labor costs.

[0030] Preferably, a control panel is installed on the top of the protective frame, and a battery is installed under the seat. The pump, solenoid valve, and geared motor are all electrically connected to the control panel, and the control panel is electrically connected to the battery.

[0031] By connecting the oiling rack to the power source, the pump, solenoid valve, and geared motor are electrically connected to the control panel, and the control panel is electrically connected to the battery. This allows for easy control of the pump to draw out rust-preventive oil, the opening and closing of the solenoid valve, and the opening and closing of the geared motor. As the device moves along the track, it can simultaneously and precisely apply oil to the inner and outer track fasteners on each side of the track. This makes operation convenient, significantly improves the efficiency of track oiling, and reduces labor costs. Attached Figure Description

[0045] Example 1

[0046] The following description, in conjunction with specific embodiments, provides further details. Figure 1-9As shown, this embodiment is a track fastener oiling device, including an oiling frame 1 and a power frame 2. The tail end of the oiling frame 1 is detachably connected to the front end of the power frame 2. Four first track wheels 11 are distributed at the four corners of the bottom of the oiling frame 1. The first track wheels 11 on the left and right sides are symmetrically arranged along the virtual central axis of the oiling frame 1 and are located on two tracks. The first track wheels 11 at the front and rear ends are fixedly connected by two first shafts 111 perpendicular to the tracks. Extension frames 14 are provided on both the left and right sides of the oiling frame 1. Multiple proximity sensors 141 are provided at the bottom of each extension frame 14. An oiling assembly is provided on the oiling frame 1. The oiling assembly includes multiple oil nozzles 143. The multiple oil nozzles 143 are symmetrically distributed on the extension frames 14 on both sides of the oiling frame 1. Two pumps 13 are also installed on the oiling frame 1, which are symmetrically distributed along the middle of the oiling frame 1. The power frame 2 has four second track wheels 21 distributed at its four corners. The second track wheels 21 on the left and right sides are symmetrically arranged along the virtual central axis of the power frame 2 and are located at the top of the two tracks. The second track wheels 21 at the front and rear ends are fixedly connected by two second shafts 22 perpendicular to the tracks. The power frame 2 is equipped with a power assembly. Extension frames 14 are provided at both ends of the oiling frame 1, and each extension frame 14 is equipped with multiple oil spray nozzles 143, which can simultaneously spray anti-rust oil on the track fasteners on the inner and outer sides of the two tracks. It is convenient to use, has high oiling efficiency, and reduces the time for transporting the oiling device. The oiling frame 1 used for oiling is detachably connected to the self-propelled power frame 2, which is convenient for separate transport and installation on the tracks. The pump 13 is used as the power source for oiling, and the pressure and flow are stable, ensuring the quality and effect of anti-rust oil spraying.

[0047] Reference Figure 1 or Figure 5 or Figure 7 or Figure 8 As shown, in this embodiment, the oiling rack 1 is further provided with an oil tank mounting rack 12, and the oil tank mounting rack 12 is provided with a clamp 121. An oil tank 122 is detachably installed in the clamp 121. The bottom of the oil tank 122 is provided with a T-shaped oil outlet 1223. The two ends of the T-shaped oil outlet 1223 are respectively connected to two pumps 13. Each pump 13 is connected to multiple oil nozzles 143 through an oil injection pipe 131. By detachably installing the oil tank 122 on the oil tank mounting rack 12, The device can distribute its weight during installation before oiling and disassembly after oiling. By connecting the T-shaped oil outlet 1223 at the bottom of the oil tank 122 to two pumps 13, the two pumps 13 can simultaneously pump rust-preventive oil to the inner and outer sides of each track. Finally, the oil is sprayed onto the track fasteners on the inner and outer sides of the track through multiple spray nozzles 143. The spraying work of the two tracks does not affect each other, so that the track fasteners under the two tracks can be accurately oiled at the same time even on curved tracks.

[0048] Reference Figure 2 or Figure 6 or Figure 9 As shown in this embodiment, a solenoid valve 142 is installed on the oil injection pipe 131 between the pump 13 and the oil injector 143. The solenoid valve 142 is used as the switch for oil injection. When oil is being injected, the solenoid valve 142 is opened, and when oil injection is not required, the solenoid valve 142 is closed to avoid waste and pollution of rust-preventive oil.

[0049] Reference Figure 2 or Figure 6 or Figure 9 As shown, in this embodiment, there are four oil spray nozzles 143 on each side of the oiling rack 1. The four oil spray nozzles 143 are symmetrically distributed in pairs along the track and are tilted back and forth, so that the virtual extension lines of the oil spray nozzles 143 on the front and rear sides intersect at the top of the fasteners on both sides of the track. By aligning the four oil spray nozzles 143 on each side of the oiling rack 1 with the front and rear ends of the top of the fasteners on the inner and outer sides of the track, when the oiling rack 1 moves forward, each fastener can be sprayed with anti-rust oil from the front and rear top at the same time, so that the spraying is uniform and dead corners are reduced.

[0050] Reference Figure 2 or Figure 3 or Figure 7 As shown, in this embodiment, at least two proximity sensors 141 are provided at the bottom of each side extension frame 14 on the oiling rack 1. The bottom of the proximity sensor 141 is aligned with the top of the fasteners on both sides of the track. The proximity sensor 141 controls the opening and closing of the solenoid valve 142. When the proximity sensor 141 detects the track fastener, it generates an electrical signal to control the solenoid valve 142 to open quickly, so that the rust-preventive oil is sprayed onto the track fastener under the action of the pump 13. As the oiling rack 1 and the power rack 2 move, when the proximity sensor 141 detects that it has left the track fastener, the proximity sensor 141 controls the solenoid valve 142 to close the circuit, and the oil nozzle 143 stops spraying the rust-preventive oil, reducing the waste and pollution of the rust-preventive oil. By having at least two proximity sensors 141 simultaneously detect the track fasteners on both sides of the track, the detection accuracy is further improved, and the debris on both sides of the track is prevented from affecting the detection effect of the proximity sensor 141.

[0051] Reference Figure 3 or Figure 5 or Figure 7 As shown, in this embodiment, the top of the oil tank 122 is provided with a dust cover 1221. The dust cover 1221 prevents external debris from entering the oil tank 122 and keeps the internal and external air pressure of the oil tank 122 consistent. This ensures that the internal and external pressure of the oil tank 122 remains consistent when the pump 13 draws out the anti-rust oil from the bottom of the oil tank 122, thereby keeping the flow rate of the pump 13 when it draws oil stable.

[0052] Reference Figure 3 or Figure 8 As shown in this embodiment, a magnetic level gauge 1222 is provided on the side wall of the oil tank 122. The magnetic level gauge 1222 makes it easy to intuitively understand the remaining amount of rust-preventive oil in the oil tank 122, so that the operator can replenish the rust-preventive oil in time, thereby increasing the completion rate of track oiling.

[0053] Reference Figure 1 or Figure 3 or Figure 5-9 As shown in any figure, in this embodiment, the power frame 2 is provided with a protective frame 23 and a seat 25. The seat 25 facilitates the operator to sit on the power frame 2, and the protective frame 23 facilitates the protection of the operator.

[0054] Reference Figure 1 or Figure 3-9 As shown in any figure, in this embodiment, safety doors 24 are hinged to both sides of the protective frame 23, and the safety doors 24 can prevent the operator from falling from both ends of the seat 25.

[0055] Reference Figure 7-8 As shown in Figure 9, in this embodiment, the tail of the oiling rack 1 is provided with a first connecting hole 15, and the front end of the power frame 2 is provided with a second connecting hole 231 that is adapted to the first connecting hole 15 on the oiling rack 1. The protective frame 23 is also provided with a pin bracket 233, and a pin 232 is detachably inserted into the pin bracket 233. The pin 232 is used to simultaneously insert into the first connecting hole 15 and the second connecting hole 231 after the first connecting hole 15 and the second connecting hole 231 are aligned, so that the bracket and the power frame 2 are connected to each other. Through the first connecting hole 15, the second connecting hole 231 and the pin 232, it is convenient to connect the oiling rack 1 and the power frame 2 together. 2. After being placed on the track, the oiling rack 1 is positioned at the front end of the power frame 2, and the first connecting hole 15 at the tail end of the power frame 2 and the second connecting hole 231 at the front end of the power frame 2 are brought close to each other and overlapped. Finally, it is fixed with the pin 232, so that the oiling rack 1 and the power frame 2 are connected together during use. When disassembly is required after the oiling operation is completed, the pin 232 is pulled out and placed on the pin holder 233 on the protective frame 23 to prevent the pin 232 from being lost. Then, the oiling rack 1 and the power frame 2 can be lifted off the track in sequence. By detachably connecting the oiling rack 1 and the power frame 2, the strength of lifting the device onto or off the track is reduced, and the labor intensity of the operator is reduced.

[0056] Reference Figure 3 or Figure 8As shown, in this embodiment, the power assembly includes a geared motor 27 and a transmission assembly 271. A transmission assembly mounting bracket 26 is fixedly connected to the power frame 2. Both the geared motor 27 and the transmission assembly mounting bracket 26 are fixedly connected to the power frame 2. The transmission assembly 271 is mounted on the transmission assembly mounting bracket 26. The geared motor 27 is driven to drive the transmission assembly 271. The transmission assembly 271 is driven to drive the second shaft 22. The geared motor 27 and the transmission assembly 271 drive the second shaft 22 to rotate, providing power for the self-movement of the power frame 2. The power frame 2 pushes the oiling rack 1 forward, realizing the device's self-movement and automatic oiling, reducing the difficulty of operation, labor intensity, and labor costs.

[0057] Reference Figure 5 or Figure 7 or Figure 8 As shown, in this embodiment, a control panel 241 is installed on the top of the protective frame 23, and a battery is installed under the seat 25. The pump 13, solenoid valve 142, and geared motor 27 are all electrically connected to the control panel 241, and the control panel 241 is electrically connected to the battery. By connecting the oiling rack 1 to the power source, the pump 13, solenoid valve 142, and geared motor 27 are electrically connected to the control panel 241, and the control panel 241 is electrically connected to the battery. This facilitates the control panel 241 to control the pump 13 to draw out rust-preventive oil, the opening and closing of the solenoid valve 142, and the opening and closing of the geared motor 27. This allows the device to simultaneously and accurately oil the inner and outer track fasteners on each side of the track while moving on the track. This is convenient to operate, greatly improves the efficiency of track oiling, and reduces labor costs.

[0058] Example 2

[0059] When using this utility model, the operator needs to move the oiling rack 1 and the power rack 2 onto the track, place the first track wheel 11 and the second track wheel 21 on the track, and position the oiling rack 1 in front of the power rack 2. Then, bring the first connecting hole 15 on the oiling rack 1 and the second connecting hole 231 on the power rack 2 close together and fix them with the pin 232 to connect the oiling rack 1 and the power rack 2. This does not affect the movement on the curved rail. After the oiling rack 1 and the power rack 2 are installed, the oil tank 122 filled with rust-preventive oil is installed on the oil tank mounting bracket 12 on the oiling rack 1. The two pipes on the T-shaped oil outlet 1223 at the bottom of the oil tank 122 are connected to the two pumps 13 respectively. When oiling begins, the reduction motor 27 and the two pumps 13 are turned on through the control panel 241. The reduction motor 27 drives the power rack 2 to move at a constant speed on the track through the transmission component 271, while simultaneously pushing the oiling rack 1 to move at a constant speed. The pumps 13 pump the oil tank... The rust-preventive oil in 122 is drawn into the spray pipe 131. As the oiling frame 1 moves on the track, when the proximity sensor 141 at the bottom of the extension frame 14 begins to approach the track fastener, it generates an electrical signal, opening the solenoid valve 142. This allows the rust-preventive oil in the spray pipe 131 to be sprayed onto the track fastener from the front and rear top of the track fastener through multiple spray nozzles 143. Under the action of different angles and high-pressure spraying, the rust-preventive oil forms a uniform oil film on the track fastener. As the oiling frame 1 and the power frame 2 move at a constant speed, the proximity sensor 141 detects that the track fastener has been sprayed and closes the solenoid valve 142, stopping the spraying of rust-preventive oil. This allows the spray nozzles 143 to only apply oil to the track fastener, reducing waste and pollution. The oiling frame 1 and the power frame 2 continue to move until the proximity sensor 141 detects that the track fastener is approaching again. Then, the solenoid valve 142 opens again, and the spray nozzles 143 apply oil to the bone carving fastener again, and this process is repeated.

[0060] Since the oiling frame 1 has extension frames 14 on both sides, and each extension frame 14 has at least four oil nozzles 143, and the four oil nozzles 143 are symmetrically distributed in pairs along the track and tilted back and forth, the virtual extension lines of the oil nozzles 143 on the front and rear sides intersect at the top of the fasteners on both sides of the track. This allows the oiling frame 1 to be pushed forward by the power frame 2 during spraying, so that a total of four track fasteners on the inner and outer sides of the two rails can be oiled at the same time. Compared with the traditional single-sided oiling, the oiling efficiency is greatly improved. At the same time, by making the power frame 2 and the oiling frame 1 detachably connected, the labor intensity required for handling during installation and disassembly is reduced. The installation is convenient and quick. During use, the operator can sit on the seat 25. Compared with the traditional method where the operator has to follow the oiling trolley at all times, the labor intensity is greatly reduced. Oiling is convenient, quick, time-saving and labor-saving.
