Description

Technical Field

[0001] This invention relates to the field of railway bolt oiling equipment technology, and in particular to an automatic railway bolt oiling device. Background Technology

[0002] The daily maintenance and repair of railway line equipment is a demanding task, with limited working time and a shortage of personnel. Most of the time is spent on inspecting and repairing track smoothness, foundation stability, and geometric dimensions, leaving little time for lubricating fastener bolts. Moreover, the numerous and long lines of track maintenance equipment make manual lubrication difficult to resolve existing problems, leading to severe corrosion and even failure due to insufficient lubrication. Especially during major overhauls such as rail replacement, sleeper replacement, and track loosening, large-scale bolt tightening and loosening often results in multiple fasteners rusting and becoming stuck, requiring removal by force; or the threads may fail after loosening, necessitating re-anchoring, which delays construction progress and increases workload.

[0003] Currently, most lubrication devices are manual, requiring manual pushing to the fastener to dispense oil intermittently. This results in discontinuous operation, reliance on manual positioning and control, and low efficiency. Therefore, developing a rapid lubrication device to replace manual labor would enable continuous operation, improve efficiency, and solve the problem of severe corrosion due to insufficient lubrication of fasteners. This is extremely important for improving the quality of track maintenance equipment and saving time. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic oil spraying device for railway bolts to solve the above-mentioned problems.

[0023] like Figure 1-5 As shown, an automatic oil spraying device for railway bolts includes a traveling frame 1, on which a moving component is installed. The moving component includes steel wheels 8 mounted on the traveling frame 1. Two steel wheels 8 in the same row are connected by a rotating shaft 9. The steel wheels 8 are driven by a drive motor 10.

[0024] The steel wheel 8 is connected to the walking frame 1 via a mounting bracket 11, and the drive motor 10 is fixed to the mounting bracket 11. The output end of the drive motor 10 is connected to one of the steel wheels 8 at the rear of the walking frame 1.

[0025] Both sides of the walking frame 1 are equipped with oiling assemblies. The oiling assembly includes a second L-plate 12 installed on both sides of the walking frame 1 and a first cylinder 13 installed on the second L-plate 12. The first cylinder 13 is connected to a second air pump 14 fixed on the walking frame 1. The telescopic end of the first cylinder 13 passes through the second L-plate 12 and is connected to an oil nozzle 15. The oil nozzle 15 is connected to an oil tank 16 installed on the walking frame 1 through a hose.

[0026] Below the fuel injection assembly is a recovery assembly, which includes an fuel collection groove 17 located below the fuel injector 15 and a second cylinder 18 mounted on the inner wall of the second L-plate 12. The telescopic end of the second cylinder 18 is connected to the outer wall of the fuel collection groove 17. The recovery assembly collects the fuel dripping from the fuel injector 15 and connects it to the fuel tank 16 via a hose connected to the bottom of the fuel collection groove 17.

[0027] A cleaning component is provided in front of the oiling assembly. The cleaning component includes a first air pump 2 fixed on the walking frame 1 and a first L-plate 3 placed outside the first air pump 2. The first L-plate 3 is mounted on the walking frame 1, and a dust suction hood 4 is installed on the first L-plate 3. The top of the dust suction hood 4 passes through the top of the first L-plate 3 and is connected to the exhaust fan 5. The inside of the dust suction hood 4 is provided with four high-pressure jet nozzles 6. The heads of the high-pressure jet nozzles 6 are all offset towards the center, and the included angle between two adjacent high-pressure jet nozzles 6 is 90°. The high-pressure jet nozzles 6 are connected to a connecting pipe 7, and the other end of the connecting pipe 7 passes through the top of the dust suction hood 4 and is connected to the first air pump 2. The fastener bolts are cleaned by air jets from the high-pressure jet nozzles 6. The dust blown up is absorbed by the dust suction hood 4 and sent into the collection box connected to the exhaust fan 5, which is beneficial for the oil to penetrate after spraying.

[0028] Both the oiling assembly and the cleaning assembly are equipped with sensing components on their outer sides. The sensing components include an adjustment assembly and a sensor 19. One end of the adjustment assembly is connected to the sensor 19, and the other end of the adjustment assembly is connected to the first L plate 3 and the second L plate 12. The sensor 19 is located on the outer side of the first L plate 3 and the second L plate 12.

[0029] The adjusting assembly includes a connecting rod 20 and a sleeve 21. The sleeve 21 is fitted onto the connecting rod 20 and has a threaded hole. A set screw 22 is threaded into the threaded hole, and the end of the set screw 22 abuts against a groove 23 on the connecting rod 20. The top of the connecting rod 20 is connected to the first L-plate 3 and the second L-plate 12, and the bottom of the sleeve 21 is connected to the sensor 19. After placing the device on the rail, loosen the set screw 22 according to the position of the fastener bolts, adjust the position of the sleeve 21 on the connecting rod 20, and then tighten the set screw 22 to fix the position of the sensor 19.

[0030] The first air pump 2, the exhaust fan 5, the drive motor 10, the first cylinder 13, the second air pump 14, the second cylinder 18, and the sensor 19 are all controlled by a control box installed on the walking frame 1. The control box is existing technology and will not be described in detail here.

[0031] The operation process of this invention is as follows:

[0032] Place the equipment on the rails so that the steel wheels 8 can roll on the rails. Then, adjust the position of the sensor 19 according to the height of the fastener bolts. Then, turn on the equipment to move the walking frame 1 forward. When the sensor 19 on the cleaning component senses the position of the fastener bolts, the drive motor 10 stops working, causing the walking frame 1 to stop. Then, the high-pressure jet nozzle 6 sprays air to clean the fastener bolts. The dust blown up is absorbed by the dust suction hood 4 and sent into the collection box connected to the exhaust fan 5. Then, the drive motor 10 works to drive the walking frame 1 to continue moving forward until the sensor 19 on the oiling component senses the position of the fastener bolts and stops moving. Then, the second cylinder 18 drives the oil receiving tank 17 to move inward so that the oil spray nozzle 15 can spray oil onto the fastener bolts. Then, the first cylinder 13 drives the oil spray nozzle 15 to descend. After descending to the appropriate position, the oil spray nozzle 15 sprays oil onto the fastener bolts. Then, they reset, completing the oiling of the fastener bolts. Then, the above actions are repeated.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
