Description

Technical Field

[0001] This invention belongs to the technical field of railway maintenance equipment, specifically, it relates to a rapid oiling device for railway concrete sleeper vertical bolts without disassembly. Background Technology

[0002] To ensure a secure connection between the rails and concrete sleepers and prevent derailment due to rail loosening, vertical bolts are typically used to connect the rails and sleepers. Then, threaded nuts are tightened onto the vertical bolts until the rails and sleepers are firmly secured. However, both the vertical bolts and nuts are exposed, and over time, environmental factors cause them to corrode, reducing their connection strength and lifespan. Therefore, regular maintenance is necessary. Current maintenance methods involve using an electric or pneumatic wrench to remove the nuts one by one, applying grease to the vertical bolts and nuts, and then tightening the nuts back onto the vertical bolts. This provides better oxidation resistance and prevents damage from friction. However, this method is labor-intensive and inefficient. Furthermore, frequent disassembly and reassembly of the fastening nuts can easily cause the bolts or fastening nuts to strip. Moreover, after the fastening nuts are loosened, the rails will also become somewhat loose. After subsequent tightening, the rails are prone to slight misalignment and deformation, all of which will affect the service life of the bolts, fastening nuts, and rails. Summary of the Invention

[0003] This invention provides a quick oiling device for railway concrete sleeper vertical bolts without disassembly, which reduces labor intensity, improves work efficiency, and enables cleaning and grease application without removing the fastening nuts on the vertical bolts, thereby extending the service life of the vertical bolts, fastening nuts, and rails.

[0010] Furthermore, the lifting drive mechanism includes an adapter seat with a fourth connecting ear. The first connecting ear and the fourth connecting ear are connected by a second connecting pin.

Specifically, the lifting drive mechanism is controlled to descend, causing the cleaning-type oiler to move towards the aligned vertical bolt. The cleaning-type oiler first cleans away debris from the vertical bolt. After cleaning, the cleaning-type oiler presses against the fastening nut on the vertical bolt, creating an oiling space at the upper end of the bolt. Then, a reciprocating pumping mechanism is controlled to extract grease from the oil storage tank, which is then pressurized and supplied to the oiling space via a distributor and oil hose. Since the vertical bolt and the fastening nut are connected by threads, a helical gap exists between them. Under high pressure, the grease is continuously applied from the upper part of the vertical bolt to the lower part through this helical gap, thus completing the oiling operation. After the oiling is completed, the lifting drive mechanism drives the cleaning-type oiler back to its original position. Then, the track-mounted trolley is controlled to move on the rail to the next position and perform the next cleaning and oiling operation. In summary, this invention can effectively reduce labor intensity, improve work efficiency, and achieve cleaning and grease application without disassembling the fastening nuts on the vertical bolts, thus extending the service life of the vertical bolts, fastening nuts, and rails.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0019] This invention discloses a rapid oiling device for railway concrete sleeper vertical bolts without disassembly, such as... Figure 1-12 As shown, the invention includes an oil storage tank 100, an adjustable assembly frame 700, a reciprocating pumping mechanism, a distributor 400, and a lifting drive mechanism 800. The oil storage tank 100 and the adjustable assembly frame 700 are both mounted on a rail-mounted vehicle. The reciprocating pumping mechanism and the distributor 400 are both located at the lower end of the oil storage tank 100, with the outlet of the oil storage tank 100 connected to the inlet of the reciprocating pumping mechanism, and the outlet of the reciprocating pumping mechanism connected to the inlet of the distributor 400. The invention employs at least one lifting drive mechanism 800, which is connected to the adjustable assembly frame 700. At least one cleaning-type oil injector 900 is connected to each lifting drive mechanism 800, and each cleaning-type oil injector 900 is used for cleaning and oiling the corresponding vertical bolts. Furthermore, the number of oil delivery hoses 500 is the same as the number of cleaning-type oilers 900. Each cleaning-type oiler 900 is connected to the outlet of the distributor 400 via its corresponding oil delivery hose 500. A control valve 501 is installed on each oil delivery hose 500. The working principle and advantages of this invention are as follows: By adjusting the shape of the adjustable assembly frame 700 and adding or removing the lifting drive mechanism 800 and the cleaning-type oiler 900, this invention enables oiling operations on single or multiple vertical bolts of the railway rails on one or both sides. Specifically, by controlling the lifting drive mechanism 800 to descend, the cleaning-type oiler 900 moves towards the aligned vertical bolt. The cleaning-type oiler 900 first brushes off debris and other contaminants from the vertical bolt. After cleaning, the cleaning-type oiler 900... The grease is pressed against the fastening nut on the vertical bolt, creating an oiling space at the upper end of the bolt. A reciprocating pumping mechanism then extracts grease from the oil reservoir 100 and supplies it to the oiling space via a distributor 400 and an oil hose 500 under pressure. Because the vertical bolt and fastening nut are threaded, a helical gap exists between them. Under high pressure, the grease is continuously applied from the upper part of the vertical bolt to the lower part through this gap, completing the oiling operation. After oiling, the lifting drive mechanism 800 drives the cleaning-type oiler 900 back to its original position. Then, the railcar moves on the rail to the next position for the next cleaning and oiling operation. In summary, this invention effectively reduces labor intensity, improves work efficiency, and achieves cleaning and grease application without disassembling the fastening nut on the vertical bolt, thus extending the service life of the vertical bolt, fastening nut, and rail.

[0020] As a preferred embodiment of the present invention, such as Figure 2 , 3As shown, the oil storage tank 100 includes an oil tank body 101, a hopper 102, and an oil tank cover 103. Two connecting seats 107 are symmetrically installed on the outer peripheral wall of the oil tank body 101, and these two connecting seats 107 are connected and fixed to a track-mounted vehicle. In this embodiment, the hopper 102 is constructed at the lower end of the oil tank body 101. The hopper 102 has a conical structure, and its small-diameter end is connected to the inlet of a reciprocating pumping mechanism. The oil tank cover 103 is located at the upper end of the oil tank body 101 and seals the upper port of the oil tank body 101. A top shell 104 protrudes upwards in the middle of the oil tank cover 103. An oil replenishment connector 106 is constructed at the center of the top shell 104. An exhaust connector 105 is constructed on the oil tank cover 103, located outside the top shell 104. Both the oil replenishment connector 106 and the exhaust connector 105 are connected to the inner cavity of the oil storage tank 100. In this embodiment, when the reciprocating pumping mechanism draws oil, the oil in the oil drum body 101 enters the reciprocating pumping mechanism through the small-diameter end of the hopper 102. When it is necessary to replenish the oil drum body 101, the oil replenishment pipe is connected to the oil replenishment connector 106, and then the oil is pressurized to smoothly enter the oil drum body 101. At the same time, the air in the oil drum body 101 is discharged through the exhaust connector 105. In this embodiment, when a large amount of oil needs to be replenished or the oil drum body 101 needs to be cleaned, the oil drum cover 103 is removed, thus opening the upper port of the oil drum body 101, which facilitates large-scale oil replenishment or cleaning operations.

[0021] As a preferred embodiment of the present invention, such as Figure 2-5As shown, the reciprocating pumping mechanism includes a pumping section 200 and a driving section 300. The inlet of the pumping section 200 is connected to the outlet of the oil storage tank 100, and the outlet of the pumping section 200 is connected to the inlet of the distributor 400. The output end of the driving section 300 is connected to the pumping section 200. In this embodiment, both the pumping section 200 and the driving section 300 are mounted on a fixed base 600. A fixed connector 601 is constructed at the upper end of the fixed base 600, and the fixed base 600 is connected and fixed to the rail-mounted vehicle through the fixed connector 601. In this embodiment, the driving section 300 drives the pumping section 200 to operate, so that the pumping section 200 draws oil from the oil storage tank 100 into the pumping section 200. Then, the oil in the pumping section 200 is pressurized and supplied to the cleaning-type oil injector 900 through the distributor 400 and the oil delivery hose 500. Specifically, the pumping unit 200 includes a sleeve-shaped end cap 207, a mounting kit 201, a piston 205, and a connecting rod 206, with all four components having coincident axes. The sleeve-shaped end cap 207 is detachably mounted on one end of the mounting kit 201, and the two are interconnected. The inner diameter of the sleeve-shaped end cap 207 is the same as that of the mounting kit 201. In this embodiment, an oil extraction pipe 208 is constructed on the peripheral wall of the sleeve-shaped end cap 207, which is connected to the small-diameter end of the discharge hopper 102 of the oil storage tank 100. An oil discharge pipe 209 is constructed at the end of the sleeve-shaped end cap 207 away from the mounting kit 201, and this oil discharge pipe 209 is connected to the inlet of the distributor 400. A first one-way valve 210 and a second one-way valve 211 are respectively installed on the oil extraction pipe 208 and the oil discharge pipe 209. When the oil flows downward through the suction pipe 208, the first one-way valve 210 opens; when the oil flows upward, the first one-way valve 210 closes. When the oil moves towards the distributor 400 within the discharge pipe 209, the second one-way valve 211 opens; when the oil moves away from the distributor 400 within the discharge pipe 209, the second one-way valve 211 closes. In this embodiment, the movable part is located within the mounting assembly 201. The outer diameter of the piston 205 is equal to the inner diameter of the mounting assembly 201. One end of the connecting rod 206 is fixed to the center of the piston 205, and the other end of the connecting rod 206 extends out of the mounting assembly 201 along its axis away from the end cap. The end of the connecting rod 206 away from the piston 205 is connected to the output end of the drive unit 300. In this embodiment, the drive unit 300 is generally a transverse cylinder or a transverse hydraulic cylinder. The drive rod of the drive unit 300 and the corresponding ends of the connecting rod 206 are coaxially connected together. The working principle and advantages of this embodiment are as follows: when the drive rod pulls the connecting rod 206 outward, the piston 205 moves toward the drive part 300. Under negative pressure, the first one-way valve 210 opens and the second one-way valve 211 closes, allowing the oil in the oil storage tank 100 to smoothly enter the sleeve-shaped end cap 207 and the fitting 201 through the oil extraction pipe 208, thereby realizing the oil extraction operation.When the drive rod pushes the connecting rod 206 inward, the piston 205 moves toward the sleeve-shaped end cap 207. Under positive pressure, the first one-way valve 210 closes and the second one-way valve 211 opens, allowing the oil to smoothly enter the distributor 400 through the oil drain pipe 209. The distributor 400 then evenly supplies the oil to each cleaning-type injector 900. In this embodiment, to improve the fluidity of the oil and enable it to be efficiently injected into the vertical bolts and fastening nuts through the cleaning-type injectors 900, the following measures are taken: an electric heating wire 203 is spirally wound around the outer side of the mounting 201, and a heat insulation shell 202 is fitted over the electric heating wire 203. The heat insulation shell 202 consists of two half-shells, which are joined together and detachably connected to the mounting 201. A seat 204 is constructed on the upper end of the outer wall of the heat insulation shell 202, and this seat 204 is detachably connected to the fixed seat 600. In this embodiment, the oil in the assembly 201 is heated by the electric heating wire 203, thereby reducing the viscosity of the oil and improving its fluidity, so that it can be smoothly injected into the connection between the bolt and the fastening nut under a predetermined pressure.

[0022] As a preferred embodiment of the present invention, such as Figure 4 , 5 As shown, the distributor 400 includes a distribution box 401 with a distribution chamber. The diameter of the distribution box 401 gradually expands along the oil conveying direction. Multiple oil outlet connectors 402 are spaced apart at the outlet end of the distribution box 401. Each oil outlet connector 402 is connected to a corresponding cleaning-type oiler 900 via an oil delivery hose 500. In this embodiment, the diameter of the distribution box 401 gradually expands along the oil conveying direction, which facilitates the rapid and uniform distribution of oil into each oil outlet connector 402 after it enters the distribution chamber, ensuring that each oil delivery hose 500 supplies oil to each cleaning-type oiler 900 at the same pressure and flow rate.

[0023] As a preferred embodiment of the present invention, such as Figure 6-8As shown, the adjustable assembly frame 700 includes an assembly base 701 and two telescopic arms. The assembly base 701 is connected and fixed to the track vehicle. A first connecting pin 702 is constructed at the lower end of the assembly base 701, and the first connecting pin 702 extends downward in the vertical direction. The telescopic arm in this embodiment includes a sleeve 703 and an arm body 708. One end of the arm body 708 is inserted into the sleeve 703, and the other end of the arm body 708 is constructed with a first connecting ear 710, which is connected to the lifting drive mechanism 800. A plurality of connecting holes 707 are spaced apart along the length direction on the sleeve 703, and a plurality of strip holes 709 are spaced apart along the length direction on the arm body 708. Each strip hole 709 extends along the length direction of the arm body 708, and multiple connecting bolts pass through the corresponding connecting holes 707 and strip holes 709. A connecting nut is threaded onto each connecting bolt. By tightening the connecting nut, the sleeve 703 and the arm body 708 are connected and fixed. In this embodiment, when the length of the telescopic arm needs to be adjusted, the connecting nuts are loosened, the connecting bolts are removed, and the length of the arm body 708 inserted into the sleeve 703 is adjusted. After adjustment, the connecting bolts are installed between the sleeve 703 and the arm body 708. Finally, the connecting nuts are installed on the connecting bolts one by one and tightened. In this embodiment, a second connecting lug 704 and a third connecting lug 705 are respectively constructed at the ends of the two telescopic arms that are close to each other. The lower end of the first connecting pin 702 passes vertically through the second connecting lug 704 and the third connecting lug 705. A first locking nut 706 is threaded onto the first connecting pin 702, thereby locking the first locking nut 706 onto the corresponding end face of the second connecting lug 704 or the third connecting lug 705. This embodiment adjusts the connection angle between the telescopic arm and the lifting drive mechanism 800, and adjusts the connection angle between the two telescopic arms, so that the multiple cleaning oilers 900 connected to the multiple lifting drive mechanisms 800 are spaced apart on the same rail or on two parallel rails, thereby realizing the cleaning and oiling operation of the vertical bolts on a single rail, or the synchronous cleaning and oiling operation of the vertical bolts on two rails.

[0024] As a preferred embodiment of the present invention, such as Figure 9As shown, the lifting drive mechanism 800 includes an adapter 801, a mounting plate 804, and a vertical drive component 806. A fourth connecting ear 802 is constructed on the adapter 801. The first connecting ear 710 and the fourth connecting ear 802 are connected by a second connecting pin 711. A second locking nut 712 is threaded onto the second connecting pin 711, locking the second locking nut 712 to the corresponding end face of the first connecting ear 710 or the fourth connecting ear 802. When it is necessary to adjust the connection angle between the telescopic arm and the lifting drive mechanism 800, first loosen the second locking nut 712 to adjust the angle between the first connecting ear 710 and the fourth connecting ear 802. Then adjust the angle between the adapter 801 and the telescopic arm. After adjustment, tighten the second locking nut 712 to lock the first connecting ear 710 and the fourth connecting ear 802. In this embodiment, a guide rail 803 is constructed on the adapter 801, extending vertically. A sliding seat 805 is constructed on the mounting plate 804, slidably connected to the guide rail 803. A vertical drive component 806 is mounted on the adapter 801. This vertical drive component 806 is generally a cylinder or hydraulic cylinder. A movable rod 807 is coaxially connected to one end of the cylinder rod of the vertical drive component 806. The lower end of the movable rod 807 movably passes through the mounting plate 804. A connecting spring 808 is fitted around the movable rod 807, with both ends of the connecting spring 808 connected to the movable rod 807 and the mounting plate 804, respectively. The working principle and advantages of this embodiment are as follows: When it is necessary to drive the cleaning-type oiler 900 to move vertically, the vertical drive component 806 is controlled to move, causing the movable rod 807 to move vertically. The movable rod 807 drives the mounting plate 804 to move vertically via the connecting spring 808, thereby causing the cleaning-type oiler 900 connected to the mounting plate 804 to move vertically. This allows the cleaning-type oiler 900 to complete the cleaning and oiling operations. After completing the cleaning and oiling operations, the cleaning-type oiler 900 is lifted away from the vertical bolt. Furthermore, because this embodiment uses the connecting spring 808, it avoids hard contact between the cleaning-type oiler 900 and the vertical bolt, preventing damage to the corresponding components. In this embodiment, to achieve simultaneous cleaning and lubrication of the vertical bolts on both sides of a single rail, an adapter plate 809 is installed on one side of the mounting plate 804. Another cleaning-type lubricator 900 is installed on the adapter plate 809, and the distance between the two cleaning-type lubricators 900 is equal to the distance between the vertical bolts on both sides of the rail. In this way, the lifting drive mechanism 800 can drive the two cleaning-type lubricators 900 to lift and lower synchronously, thereby achieving cleaning and lubrication of the corresponding vertical bolts on both sides of a single rail.

[0025] As a preferred embodiment of the present invention, such as Figure 10-12As shown, the cleaning-type oiler 900 includes an oil injection pipe 901, a pneumatic drive assembly, and a cleaning component connected vertically downwards in sequence. The oil injection pipe 901 is connected to the lifting drive mechanism 800, and the cleaning component is fitted onto the outside of the vertical bolt. Specifically, in this embodiment, a connecting flange 902 is constructed on the upper part of the oil injection pipe 901, and the oil injection pipe 901 is connected and fixed to the mounting plate 804 of the lifting drive mechanism 800 through the connecting flange 902. A mounting base 903 is constructed at the lower end of the oil injection pipe 901. The pneumatic drive assembly in this embodiment includes an impeller housing, a conical wheel 911, an assembly pipe 907, and a pressure seat 913. The conical wheel 911 is fitted and fixed onto the outside of the assembly pipe 907, with the large-diameter end of the conical wheel 911 facing downwards. Multiple pneumatic blades 912 are evenly constructed around the conical wheel 911 along its circumference, and the impeller housing is fitted onto the conical wheel 911. The impeller housing in this embodiment includes a first impeller half-shell 904 and a second impeller half-shell 906 that are interlocked. An air inlet connector 905 is constructed on the first impeller half-shell 904. A connector pipe 908 is constructed at the upper end of the assembly pipe 907. A bearing 910 is assembled outside the connector pipe 908. A mounting base 903 is fitted and fixed outside the bearing 910, and the mounting base 903 is detachably connected to the upper end of the impeller housing. In this embodiment, the pressure seat 913 is constructed at the lower end of the assembly pipe 907. Multiple air guide holes 909 are spaced apart on the pressure seat 913, each air guide hole 909 connecting the inner cavity of the impeller housing to the cleaning component. At least two sealing rings 914 are assembled at the lower end of the pressure seat 913. When the pressure seat 913 is driven down to its lowest position, it presses against the upper surface of the fastening nut on the vertical bolt. Under the action of the sealing rings 914, the oil injection pipe 901 is separated from the lower part of the vertical bolt by the fastening nut. Specifically, the cleaning component in this embodiment includes a connecting outer sleeve 915 and a connecting inner sleeve 916. The connecting outer sleeve 915 is constructed at the lower end of the pressure seat 913, and its axis coincides with that of the pressure seat 913. The connecting inner sleeve 916 is coaxially constructed inside the connecting outer sleeve 915, and an air chamber 917 is formed between the connecting outer sleeve 915 and the connecting inner sleeve 916. In this embodiment, bristles 918 are constructed on the peripheral wall of the connecting inner sleeve 916. The bristles 918 extend spirally along the axis of the connecting inner sleeve 916. Furthermore, a plurality of air holes 919 are constructed at intervals on the peripheral wall of the connecting inner sleeve 916. These air holes 919 are all connected to the air chamber 917.The working principle and advantages of this embodiment are as follows: When the cleaning-type oiler 900 is driven to move downwards, the cleaning brush gradually covers the outside of the vertical bolt. At the same time, high-pressure gas is introduced into the impeller housing, which then drives the conical wheel 911 to rotate through the pneumatic blades 912. The conical wheel 911 drives the cleaning brush to rotate through the pressure seat 913, thereby causing the bristles 918 on the cleaning brush to clean the vertical bolt from top to bottom. Simultaneously, the gas in the impeller housing enters the air chamber 917 through the air guide hole 909, and then is ejected from the air chamber 917 through the air blowing hole 919, so that the airflow blows onto the vertical bolt, working with the bristles 918 to completely remove the debris from the vertical bolt. In this embodiment, because the bristles 918 adopt a spiral arrangement, the debris brushed off gradually moves downwards away from the vertical bolt and is discharged from the lower end of the cleaning brush under the drive of the airflow. When the pressure seat 913 abuts against the fastening nut, the high-pressure gas supply is stopped, and then the cleaning-type oiler 900 continues to move downward until the pressure of the pressure seat 913 on the fastening nut reaches a predetermined range. Then, the reciprocating pumping mechanism is controlled to pressurize the oil and inject it into the oil injection space through the oil injection pipe 901. Under high pressure, the oil enters the helical gap between the vertical bolt and the fastening nut, achieving the purpose of oil injection. In this embodiment, a rubber seat 920 is constructed at the lower end of the connecting sleeve 915, which coincides with its axis. The diameter of the rubber seat 920 gradually expands downward in the vertical direction. The rubber seat 920 serves two purposes: protecting the lower end of the cleaning component and guiding the flow, allowing debris to be smoothly discharged from the cleaning component. In this embodiment, the connecting inner sleeve 916 can be made of rubber material. After the high-pressure gas enters the air chamber 917 through the air guide hole 909, the connecting inner sleeve 916 expands, thereby bringing the connecting inner sleeve 916 closer to the vertical bolt. This allows the brush bristles 918 to fully contact the vertical bolt and the fastening nut, and clean the debris attached to their surfaces. Moreover, the airflow ejected from the air blowing hole 919 can more fully and powerfully blow away the cleaned debris.
