Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and in particular to an oil injection device. Background Technology

[0002] The invention patent with authorization announcement number CN 200999949Y discloses a downhole wire rope lubricator, which injects grease into an oil tank consisting of a top cover and a housing. As the wire rope passes through the oil tank, the grease is evenly distributed inside the wire rope. However, during use, although the grease covers the surface of the wire rope, it only lubricates and prevents corrosion on the surface. Most of the grease cannot penetrate into the interior of the wire rope, making internal wear between strands unavoidable and reducing the load-bearing capacity of the wire rope. Therefore, a lubrication device should be designed to lubricate both the inside and outside of the wire rope. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies where grease cannot fully penetrate into the interior of the wire rope, and to propose an oil injection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an oil injection device, including an oil tank, with oil seal devices at both ends of the oil tank. The surface of the oil tank has several through grooves along the circumference. The inner wall of the oil tank is fixed with several compression cylinders that correspond one-to-one with and communicate with the through grooves along the circumference. The end of the compression cylinder away from the through groove is covered and fixed with a flexible membrane. A compression plate is installed inside the compression cylinder. The compression plates are all connected to the same drive module. The drive module is used to drive the compression plates to reciprocate inside the compression cylinder, so that the compression plates can repeatedly compress the gas between the flexible module and the compression plate.

[0006] Preferably, the drive module includes a first magnetic chuck, a second magnetic chuck, and a ring motion mechanism. Each compression plate has a first magnetic chuck fixed to it, and a plurality of second magnetic chucks are arranged around the central axis of the oil tank. The first magnetic chuck and the second magnetic chuck are arranged in a one-to-one correspondence and repel each other. The second magnetic chucks are all connected to the ring motion mechanism, which drives all the second magnetic chucks to synchronously perform reciprocating circular motion around the central axis of the oil tank.

[0007] Preferably, a vibrating plate is provided between every two compression cylinders. The vibrating plate, together with the outer walls of the two compression cylinders and the inner wall of the oil tank, forms a sealed cavity. A vibration mechanism is provided in the sealed cavity to vibrate the vibrating plate.

[0008] Preferably, the vibration mechanism includes a vibrating plate and a third magnetic attractor. A plurality of vibrating plates are provided in the sealed cavity. One end of each vibrating plate is connected to a vibrating plate, and the other end of each vibrating plate is bent to one side and fixed with a third magnetic attractor. The third magnetic attractor and the second magnetic attractor attract each other.

[0009] Preferably, both the vibrating plate and the vibrating sheet are made of metal.

[0010] Preferably, the fuel tank is made of fiber-reinforced plastic material.

[0011] Preferably, the oil sealing device includes a tubular body, a first sealing element, and a second sealing element. The first sealing element and the second sealing element are embedded in the inner wall of the tubular body. The first sealing element consists of two semi-circular sealing rings, and the second sealing element consists of two semi-circular sealing air bladders. Both sealing air bladders are connected to any one of the compression cylinders through an air supply pipeline, so that when the gas in the compression cylinder is compressed, some of the gas can enter the sealing air bladders.

[0012] The oil injection device proposed in this invention has the following advantages: By setting up a pressurizing device, the operator can intermittently pressurize the grease in the oil tank by reciprocatingly pressing the handle. Combined with the intermittently moving steel wire rope, the pressurized grease can better penetrate into the core of the steel wire rope in the oil tank, so that both the inside and outside of the steel wire rope can be lubricated and protected against corrosion. At the same time, a vibration mechanism linked to the drive module in the pressurizing device is also set up. The vibration mechanism causes the grease in the oil tank to vibrate. The vibrating grease can open up the gaps on the surface of the steel wire rope, further improving the penetration rate of the grease into the steel wire rope. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1

[0026] Reference Figure 1-10An oil filling device includes an oil tank made of fiber-reinforced plastic. Fiber-reinforced plastic can be made of fiberglass, which has high strength and does not reduce magnetic fields. The tank body 2 adopts a split design, comprising a tank body 2 and a top cover 1. The tank body 2 and the top cover 1 are fixedly connected together by bolts, nuts, or other fasteners. An oil inlet pipe and an exhaust pipe, communicating with the interior of the tank body 2, are provided on the surface of either the tank body 2 or the top cover 1. The oil inlet pipe is used for adding lubricating grease, and the exhaust pipe is used to expel internal gases during the filling process. Oil seal devices are provided at both ends of the oil tank to seal the ends of a steel wire rope passing through the tank, reducing grease leakage during the rope's movement. The oil seal device is cylindrical in shape, with two semi-circular arc plates forming a tubular main body 23, which is connected to the tank body 2 and the top cover 1 respectively. The surface of the oil tank has several through slots 3 circumferentially oriented. Several compression cylinders 4, corresponding one-to-one with and connected to the through slots 3, are fixedly installed circumferentially on the inner wall of the oil tank. A flexible membrane 5 is covered and fixed to the end of each compression cylinder 4 away from the through slots 3. Compression plates 6 are installed inside the compression cylinders 4, and all compression plates 6 are connected to the same drive module. The drive module drives the compression plates 6 to reciprocate within the compression cylinders 4, allowing the compression plates 6 to repeatedly compress the gas between the flexible module and the compression plates 6. Several springs are installed between the compression plates 6 and the flexible membrane. One end of each spring is fixedly connected to the compression plate 6, and the other end is fixedly connected to the inner wall of the compression cylinder via a connecting plate 7. By using these springs, the compression plates 6 can be automatically reset.

[0027] The drive module includes a first magnetic chuck 8, a second magnetic chuck 9, and a ring motion mechanism. Each compression plate 6 has a first magnetic chuck 8 fixed to it. Several second magnetic chucks 9 are arranged around the central axis of the oil tank. The first magnetic chuck 8 and the second magnetic chuck 9 are arranged in a one-to-one correspondence, and they repel each other. All second magnetic chucks 9 are connected to the ring motion mechanism, which drives all the second magnetic chucks 9 to synchronously reciprocate in a circular motion around the central axis of the oil tank. (Refer to...) Figure 8-10The ring motion mechanism includes a fixed ring 11, a ring track 12, a movable ring 13, an incomplete toothed ring 10, a gear 14, a rotating shaft 15, a pressure rod 16, and a limiting mechanism. A fixed ring 11 is coaxially fixed at each end of the housing 2. A ring track 12 is coaxially fixed to the inner side of each fixed ring 11. A movable ring 13 is coaxially inserted into each ring track 12. The two ends of the second magnetic suction member 9 are fixedly connected to the corresponding movable ring 13. An incomplete toothed ring 10 is coaxially fitted on the housing 2. The second magnetic suction member 9 is connected to the incomplete toothed ring 10. A rotatable mechanism is installed between the two fixed rings 11. A rotating shaft 15 has a drive gear 14 coaxially fixedly mounted on it. The drive gear 14 meshes with an incomplete gear 14. A pressure rod 16 is fixed at one end of the rotating shaft 15. A limit mechanism is provided on the pressure rod 16 to limit the swing range of the pressure rod 16. The limit mechanism includes a limit plate 17, a limit groove 18, and a limit shaft 19. The limit plate 17 is fixedly connected to any one of the fixed rings 11. An arc-shaped limit groove 18 coaxially opened on the limit plate 17 is provided, and a limit shaft 19 is inserted into the arc-shaped limit groove 18. The limit shaft 19 is fixedly connected to the pressure rod 16. The function of this limiting mechanism is to allow the operator to make only a small range of swings during the reciprocating pressing of the pressure rod 16. When the operator pushes the pressure rod 16 upward to the uppermost end of the limiting groove 18, the entire drive module can drive each second magnetic block to move to the position where it interacts with the first magnetic block. The operator only needs to maintain this posture, and the first magnetic block will push the compression plate 6 to continuously compress the gas. When the operator pushes the pressure rod 16 downward to the lowermost end of the limiting groove 18, the first magnetic block and the second magnetic block can be misaligned and do not interact.

[0028] In use, after securing the entire oil tank, open the top cover 1, then place the steel wire rope into the tank body 2, and then close the top cover 1. Finally, add grease through the oil filling pipe on the oil tank. After the grease is added, the operator presses down on the pressure rod 16. The pressure rod 16 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the gear 14 to rotate, the gear 14 drives the incomplete gear ring 10 to rotate, and the incomplete gear ring 10 drives multiple second magnetic suction components 9 to rotate synchronously. When each second magnetic suction component 9 rotates to the position corresponding to the first magnetic suction component 8, the first magnetic suction component 8 pushes the compression... Plate 6 moves toward the flexible membrane 5, thereby squeezing the gas inside the compression cylinder 4, causing the flexible membrane 5 to expand. The expansion of the flexible membrane 5 squeezes the grease in the oil tank. The synchronous expansion of multiple flexible membranes 5 increases the pressure of the grease in the oil tank due to the compression. The increased pressure allows the grease to better penetrate into the core of the wire rope. Then, the operator lowers the pressure rod 16 to reset it. At this time, the grease pressure returns to normal. Then, the cooperating operator pulls the wire rope to remove the greased wire rope. The above operation is repeated until all the wire ropes have been greased.

[0029] Example 2

[0030] Reference Figure 6-7 In another preferred embodiment of the present invention, the difference from Embodiment 1 is that a vibrating plate 20 is provided between every two compression cylinders 4. The vibrating plate 20, the outer wall of the two compression cylinders 4, and the inner wall of the oil tank form a sealed cavity. A vibration mechanism is provided in the sealed cavity to vibrate the vibrating plate 20. By providing a vibration mechanism, the vibrating plate 20 is vibrated, and the vibration plate 20 transmits the vibration to the grease in the oil tank, causing the grease in the oil tank to vibrate. The vibrating grease can clear the gaps on the surface of the wire rope, further improving the grease's penetration rate into the wire rope.

[0031] The vibration mechanism includes vibrating plates 21 and a third magnetic chuck 22. Several vibrating plates 21 are arranged within the sealed cavity. One end of each vibrating plate 21 is connected to the vibrating plate 20, and the other end of each vibrating plate 21 is bent to one side and fixed with a third magnetic chuck 22. The third magnetic chuck 22 attracts the second magnetic chuck 9. By using the third magnetic chuck 22, whenever the second magnetic chuck 9 moves, when the second magnetic chuck 9 reaches the position corresponding to the third magnetic chuck 22, the third magnetic chuck 22 is attracted by the second magnetic chuck 9, thus pulling the bent end of the vibrating plate 21 outward. When the second magnetic chuck 9 and the third magnetic chuck 22 are misaligned, the third magnetic chuck 22 is pulled back by the restoring force of the vibrating plate 21. The entire vibrating plate 21 thus generates high-frequency vibration, which is further transmitted to the vibrating plate, causing it to vibrate. This vibration mechanism can be synchronously driven by the drive module, making it more convenient to use. Both the vibrating plate 20 and the vibrating plates 21 are made of metal.

[0032] Example 3

[0033] Traditional oil seal devices require a very tight seal to prevent grease leakage under increased pressure. This results in high frictional resistance between the wire rope and the seal, making the removal process slow. (Refer to...) Figure 4-5In another preferred embodiment of the present invention, the difference from Embodiment 1 is that the oil sealing device includes a tubular body 23, a first sealing element 24, and a second sealing element 25. The first sealing element 24 and the second sealing element 25 are embedded in the inner wall of the tubular body 23. The first sealing element 24 consists of two semi-circular sealing rings, and the second sealing element 25 consists of two semi-circular annular sealing air bladders. Both sealing air bladders are connected to any one of the compression cylinders 4 through an air supply pipe 26, so that when the gas in the compression cylinder 4 is compressed, some of the gas can enter the sealing air bladders. This oil sealing device adds a sealing air bladder to the traditional sealing rings. Whenever the pressure in the oil tank increases, since the sealing air bladder is connected to the compression cylinder 4, some of the compressed gas enters the sealing air bladder, causing the sealing air bladder to expand. The expanded sealing air bladder further improves the sealing performance between the tubular body 23 and the wire rope. In this way, when the pressurizing module pressurizes, the expanding sealing bladder can prevent the grease from leaking due to increased pressure. When the pressurizing module stops, the sealing bladder contracts. This reduces the frictional resistance between the wire rope and the sealing bladder during the removal of the wire rope after oil injection, allowing it to be removed more smoothly.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
