Description

Technical Field

[0001] This utility model relates to the field of railway track maintenance technology, specifically a fastener oiling device for railway construction. Background Technology

[0002] Rail fasteners are intermediate components that connect rails and sleepers. They require reliable connection, simple structure, easy assembly and disassembly, and properties such as elasticity, vibration damping, and insulation. Different types of sleepers and ballastless tracks use different fasteners. Wooden sleeper fasteners include ordinary spikes and iron pads, while concrete sleeper fasteners include plate fasteners, arched spring clip fasteners, and spring bar fasteners.

[0003] Lubricating railway fasteners typically involves applying a paste-like lubricant to the fasteners. This is usually done manually by track inspectors using brushes, a process that requires bending over, which can lead to back fatigue. Therefore, a fastener lubrication device for railway construction is proposed to address this problem. Utility Model Content

[0025] Please see Figures 1-5In this embodiment of the present invention, a fastener oiling device for railway construction includes a sleeve 2 adapted to the fastener mounting screw 1. The inner top of the sleeve 2 is divided into an oiling chamber 3 and a transmission chamber 4 by a partition. A rotating shaft 5 is provided on the inner circumference of the oiling chamber 3. The rotating shaft 5 is rotatably connected to the oiling chamber 3. Brush bristles 6 are uniformly fixedly connected to the outer wall of the rotating shaft 5.

The upper part of the rotating shaft 5 is inserted into the transmission chamber 4 and is fixedly connected to a first gear 8. The first gears 8 are connected to each other by a second gear 9 that meshes with them. The second gear 9 is fixedly installed on the drive motor 1. At the output end of 0, the drive motor 10 is fixedly installed on the top surface of the sleeve 2 and its output shaft is inserted into the transmission cavity 4. An extension rod 11 is fixedly connected to the top surface of the sleeve 2. An electrical cavity 12 is provided on the inner bottom side of the extension rod 11. An oil storage cavity 13 is provided on the inner top side of the extension rod 11. The oil storage cavity 13 is filled with the lubricating oil to be applied. The electrical cavity 12 is covered on the outside of the drive motor 10. A mobile power supply 14 is fixedly installed on the inner upper part of the electrical cavity 12. The top end of the rotating shaft 5 is rotatably connected to a connecting pipe 15 through a rotating pipe joint 16. The rotating pipe joint 16 passes through the top of the sleeve 2. One end of the connecting pipe 15 is connected to the bottom of the oil storage cavity 13.

[0026] The drive motor 10, in conjunction with the first gear 8 and the second gear 9, drives the rotating shaft 5 to rotate. The connecting pipe 15, in conjunction with the hollow rotating shaft 5, guides the lubricating oil in the oil storage chamber 13 to the oil outlet 7, so that it can be easily brushed onto the fastener mounting screw 1 by the brush bristles 6. The sleeve 2 is extended downward by the extension rod 11, so that there is no need to bend over to operate, which greatly reduces back fatigue.

[0027] The bottom of the sleeve 2 is provided with an opening, and the extension rod 11 is provided with heat dissipation holes evenly distributed in the electrical cavity 12.

[0028] The top end of the extension rod 11 is connected to the oil reservoir 13 via an injection mechanism 17, which includes a threaded cap 18, an electric push rod 19, and an injection piston 20.

[0029] The threaded cap 18 is threaded to the top of the extension rod 11. The extension rod 11 has an external thread on the outer side of its top. The electric push rod 19 is fixedly connected to the top surface of the threaded cap 18. The telescopic end of the electric push rod 19 slides through the threaded cap 18 and is fixedly connected to the injection piston 20. The injection piston 20 is adapted to the oil storage chamber 13. The injection piston 20 can be inserted into the oil storage chamber 13 and is slidably connected.

[0030] The threaded cap 18, which is assembled by threads, allows the top of the oil reservoir 13 to be opened, thus facilitating the replenishment of lubricating oil.

[0031] The injection piston 20 is pushed by the electric push rod 19, so that the lubricating oil in the oil storage chamber 13 can be transported to the oil outlet 7 through the connecting pipe 15 and the rotating shaft 5 and then output to the brush bristles 6.

[0032] A protective sleeve 21 is fixedly connected to the top surface of the threaded cap 18, and the protective sleeve 21 is sleeved on the outside of the electric push rod 19.

[0033] A sliding sleeve 22 is slidably connected to the outer side of the protective sleeve 21. A handle 23 is symmetrically fixedly connected to the side wall of the sliding sleeve 22. A switch 24 is fixedly installed on the handle 23. A fixing bolt 25 is threadedly connected to the sliding sleeve 22. The fixing bolt 25 passes through the sliding sleeve 22 and abuts against the protective sleeve 21. A threaded hole for threaded connection of the fixing bolt 25 is opened on the sliding sleeve 22.

[0034] The protective sleeve 21 extends upward on the top surface of the threaded cover 18, and the handle 23 can be adjusted in position by sliding the sliding sleeve 22 on the protective sleeve 21 and locked in place by the fixing bolt 25. This allows the height of the handle 23 to be adjusted for user convenience.

[0035] Switch 24 is electrically connected to mobile power supply 14 via wires, and drive motor 10 and electric push rod 19 are both electrically connected to switch 24 via wires.

[0036] The working principle of this utility model is as follows:

[0037] In use, unscrew the threaded cap 18, fill the oil reservoir 13 with lubricating oil, then replace the threaded cap 18, allowing the injection piston 20 to insert into the oil reservoir 13, and tighten the threaded cap 18. Loosen the fixing bolt 25, allowing the handle 23 to be adjusted in position via the sliding sleeve 22 along the protective sleeve 21. After adjustment, tighten the fixing bolt 25 to fix the position of the sliding sleeve 22 and the protective sleeve 21. Then, use the handle 23 to lift the entire device and place the sleeve 2 onto the fastener mounting screw 1. At this point, the drive motor 10 and the electric push can be started via the switch 24. The electric push rod 19 pushes the injection piston 20, thereby squeezing the lubricating oil in the oil storage chamber 13 into the connecting pipe 15. The lubricating oil in the connecting pipe 15 enters the hollow rotating shaft 5 through the rotating pipe joint 16. After being squeezed out onto the rotating shaft 5, the lubricating oil is further squeezed onto the brush bristles 6. The drive motor 10 drives the second gear 9 to rotate. The second gear 9 drives the rotating shaft 5 to rotate through the first gear 8. The rotating shaft 5 drives the brush bristles 6 to rotate, thereby the rotating brush bristles 6 apply the lubricating oil onto the fastener mounting screw 1. At this time, the device can be rotated by the handle 23 to make the application more even.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
