Description

Technical Field

[0001] This utility model relates to the technical field of lubrication equipment, and more specifically to a wire rope grease filling device. Background Technology

[0002] Currently, container terminals generally employ dedicated bridge cranes or gantry cranes for container handling, while liquid handling terminals typically use grease-coated booms for loading and unloading. The spreader cable system, grease-coated boom drive cable system, and boarding ladder floor lifting drive cable system, as core transmission components, usually require grease application for lubrication and surface protection. However, it is worth noting that in these high-altitude operation scenarios where equipment heights generally exceed 15 meters, traditional manual grease application methods pose significant safety risks. Specifically, operators must perform high-altitude grease application while in a dynamically suspended state or climbing, which not only makes it difficult to ensure operational safety but also, due to the randomness of manual operation, often results in uneven grease application, urgently requiring improvement. Utility Model Content

[0003] The purpose of this invention is to solve the problem that in the existing technology, manually applying grease to cables not only makes it difficult to ensure the safety of the operation, but also often results in uneven application of grease due to the randomness of manual operation, which urgently needs improvement.

[0004] To address the aforementioned problems, this utility model provides a wire rope grease filling device, comprising a lubrication seat, a grease reservoir, and a drive assembly. The lubrication seat has a vertical grease injection hole through which the cable can pass. The grease reservoir is connected to the outside of the lubrication seat and has an upward-opening grease storage chamber. A piston is installed inside the grease storage chamber, and the piston is driven by the drive assembly to move up and down within the grease storage chamber. The grease reservoir has a grease delivery hole located below the piston, and the grease delivery hole connects the grease storage chamber and the grease injection hole.

[0005] In the above-described solution, the lubrication seat is attached to the cable requiring lubrication via a grease injection hole, and then moves along the cable by its own weight or traction. During this movement, the drive assembly lowers the piston, causing the grease in the grease reservoir to flow continuously and stably through the grease inlet to the grease injection hole, thus lubricating the cable within the injection hole. Compared to existing technologies, this solution only requires attaching the lubrication seat to the cable to apply grease, offering better safety. Furthermore, the drive assembly provides stable control over the amount of grease applied, ensuring more even application and improving practicality.

[0006] In an improved embodiment, the drive assembly includes a motor connected to a lubrication seat. Guide wheels are rotatably connected above and below the grease reservoir about a transverse axis. An annular receiving wire is wound between the two guide wheels. The lower end of the grease reservoir has a small hole through which the receiving wire can pass. The output end of the motor acts on either guide wheel, causing the guide wheel to drive the receiving wire to move. The piston is connected to the receiving wire and is driven by the receiving wire to achieve lifting and lowering. The above structure has good reliability and is easy to maintain.

[0007] In an improved embodiment, half of the receiving line is located inside the grease reservoir and the other half is located outside the grease reservoir, so that the position of the piston can be determined by observing the receiving line located outside the grease reservoir.

[0008] In an improved embodiment, the lower end of the grease reservoir is provided with a sealing ring arranged around the fine hole, the sealing ring abutting against the receiving line to achieve a seal, thereby improving the sealing performance between the fine hole and the receiving line through the sealing ring.

[0009] In an improved embodiment, there are two grease reservoirs connected to opposite sides of the lubrication seat, thereby increasing the grease loading capacity, and the two grease reservoirs can respectively deliver grease to both sides of the grease injection hole through the grease delivery hole.

[0010] In an improved embodiment, the drive assembly includes a motor, a first bevel gear, and a second bevel gear. The motor is connected to a lubrication seat. Guide wheels are rotatably connected above and below the grease reservoir about a transverse axis. An annular receiving wire is wound between the two guide wheels of the same grease reservoir. The lower end of the grease reservoir has a small hole through which the receiving wire can pass. One guide wheel of one grease reservoir is rotatably connected to the corresponding grease reservoir via a first rotating shaft, and the first bevel gear is connected to the first rotating shaft. One guide wheel of the other grease reservoir is rotatably connected to the corresponding grease reservoir via a second rotating shaft. The first and second rotating shafts... The shafts are coaxially arranged, and the opposite ends of the first and second rotating shafts are provided with meshing parts. The second rotating shaft can move axially to realize the meshing parts of the first and second rotating shafts closing or separating. The output end of the motor is connected to the second bevel gear. The first and second bevel gears mesh with each other. When the meshing parts of the first and second rotating shafts separate, only the first rotating shaft rotates under the action of the motor, that is, only one grease reservoir supplies grease to the grease injection hole. When the meshing parts of the first and second rotating shafts close, the first and second rotating shafts rotate synchronously, and both grease reservoirs supply grease to the grease injection hole at the same time.

[0011] In an improved embodiment, the lubrication seat includes a left housing and a right housing. The grease injection hole is formed by the opposing surfaces of the left and right housings. The rear sides of the left and right housings are hinged to each other. The front sides of the left and right housings are controlled to open and close by a locking mechanism. When the locking mechanism opens the front sides of the left and right housings, the cable can be easily attached. After closing the front sides of the left and right housings, the locking mechanism locks the lubrication seat securely attached to the cable.

[0012] In an improved embodiment, a receiving sleeve is provided on the front side of the left housing, and a locking sleeve is provided on the front side of the right housing. The locking sleeve and the receiving sleeve are arranged vertically and coaxially with each other. The locking element is a pin, which is used to slide into the locking sleeve and the receiving sleeve. The upper end of the pin has a first bend for resting on the upper side of the locking sleeve, thereby locking the front sides of the left and right housings can be achieved by means of the pin, making the operation simple and convenient.

[0013] In an improved embodiment, the locking sleeve and the receiving sleeve are spaced apart vertically. The side wall of the locking sleeve has a vertically penetrating opening through which a first bend of the pin can pass. The locking element also includes a spring. The lower end of the pin has a second bend extending to the underside of the receiving sleeve. The spring is sleeved on the lower end of the pin and abuts against the receiving sleeve and the second bend, thereby applying a downward force to the pin. By incorporating a spring, the frictional resistance when the first bend abuts against the upper side of the locking sleeve can be effectively increased, preventing the pin from accidentally dislodging.

[0014] In an improved embodiment, the upper side of the lubrication seat is provided with a hook, so that a traction rope can be connected to the hook from the outside, and the lubrication seat can be raised by pulling the traction rope. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1-4 The present invention provides a wire rope grease filling device, including a lubrication seat 1, a grease reservoir 2 and a drive assembly. The lubrication seat 1 has a vertical grease filling hole 11 through which the cable can pass. The grease reservoir 2 is connected to the outside of the lubrication seat 1. The grease reservoir 2 has a grease storage cavity 21 with an upward opening. A piston 22 is provided in the grease storage cavity 21. The piston 22 is driven by the drive assembly to move up and down in the grease storage cavity 21. The grease reservoir 2 has a grease delivery hole 23 located below the piston 22. The grease delivery hole 23 connects the grease storage cavity 21 and the grease filling hole 11.

[0026] In the above-described solution, the lubrication seat 1 is fitted onto the cable requiring lubrication via the grease injection hole 11, and then moves along the cable by its own weight or traction. During this movement, the drive assembly lowers the piston 22, causing the grease in the grease reservoir 21 to flow continuously and stably through the grease delivery hole 23 to the grease injection hole 11, thus lubricating the cable within the grease injection hole 11. Compared to existing technologies, this solution only requires fitting the lubrication seat 1 onto the cable to apply grease, offering better safety. Furthermore, the drive assembly provides stable control over the amount of grease applied, ensuring more uniform application and practicality.

[0027] In this embodiment, the drive assembly includes a motor 31 connected to the lubrication seat 1. Guide wheels 4 are rotatably connected above and below the grease reservoir 2 with the transverse axis as the axis. An annular receiving wire 5 is wound between the two guide wheels 4. The lower end of the grease reservoir 2 is provided with a fine hole 24 through which the receiving wire 5 can pass. The output end of the motor 31 acts on either guide wheel 4 so that the guide wheel 4 drives the receiving wire 5 to move. The piston 22 is connected to the receiving wire 5 and is driven by the receiving wire 5 to achieve lifting and lowering. The above structure has good reliability and is easy to maintain.

[0028] Furthermore, half of the receiving line 5 is located inside the grease reservoir 21 and the other half is located outside the grease reservoir 2, so the position of the piston component 22 can be determined by observing the receiving line 5 located on the outside of the grease reservoir 2. Of course, the receiving lines 5 can also be located inside the grease reservoir 2, in which case it is only necessary to provide two small holes 24 at the lower end of the grease reservoir 2.

[0029] Furthermore, the lower end of the grease reservoir 2 is provided with a sealing ring 25 arranged around the fine hole 24. The sealing ring 25 abuts against the receiving line 5 to achieve a seal, thereby improving the sealing performance between the fine hole 24 and the receiving line 5 through the sealing ring 25.

[0030] As an improvement to this embodiment, there are two grease reservoirs 2, which are respectively connected to opposite sides of the lubrication seat 1, thereby increasing the grease loading capacity. The two grease reservoirs 2 can respectively deliver grease to both sides of the grease injection hole 11 through the grease delivery hole 23. The drive assembly includes a motor 31, a first bevel gear 32, and a second bevel gear 33. The motor 31 is connected to the lubrication seat 1. Guide wheels 4 are rotatably connected to the top and bottom of the grease reservoirs 2 about the transverse axis. An annular receiving wire 5 is wound between the two guide wheels 4 of the same grease reservoir 2. The lower end of the grease reservoir 2 is provided with a fine hole 24 through which the receiving wire 5 can pass. One guide wheel 4 of one grease reservoir 2 is rotatably connected to the corresponding grease reservoir 2 via a first rotating shaft 41, and the first bevel gear 32 is connected to the first rotating shaft 41. One guide wheel 4 of the other grease reservoir 2 is rotatably connected to the corresponding grease reservoir 2 via a second rotating shaft 42. The first rotating shaft 41 and the second rotating shaft 42 are coaxially arranged. The first shaft 41 and the second shaft 42 are provided with a meshing part 43 at their opposite ends. The second shaft 42 can move axially to allow the meshing parts 43 of the first shaft 41 and the second shaft 42 to close or separate. The output end of the motor 31 is connected to the second bevel gear 33. The first bevel gear 32 and the second bevel gear 33 mesh. When the meshing parts 43 of the first shaft 41 and the second shaft 42 are separated, only the first shaft 41 rotates under the action of the motor 31, that is, only one grease reservoir 2 supplies grease to the grease injection hole 11. When the meshing parts 43 of the first shaft 41 and the second shaft 42 are closed, the first shaft 41 and the second shaft 42 rotate synchronously, and both grease reservoirs 2 supply grease to the grease injection hole 11 simultaneously. In this embodiment, the meshing part 43 of the first shaft 41 is a key, and the meshing part 43 of the second shaft 42 is a keyway.

[0031] In this embodiment, the lubrication seat 1 includes a left housing 12 and a right housing 13. The grease injection hole 11 is formed by the opposing surfaces of the left housing 12 and the right housing 13. The rear side of the left housing 12 and the rear side of the right housing 13 are hinged to each other. The front side of the left housing 12 and the front side of the right housing 13 are controlled by a locking member. When the locking member controls the front side of the left housing 12 and the front side of the right housing 13 to open, the cable can be easily connected. After the front side of the left housing 12 and the front side of the right housing 13 are closed, they are locked by the locking member, and the lubrication seat 1 is stably connected to the cable.

[0032] More specifically, a receiving sleeve 14 is provided on the front side of the left housing 12, and a locking sleeve 15 is provided on the front side of the right housing 13. The locking sleeve 15 and the receiving sleeve 14 are arranged vertically and coaxially with each other. The locking element is a pin 6, which is used to slide into the locking sleeve 15 and the receiving sleeve 14. The upper end of the pin 6 has a first bend 61 for resting on the upper side of the locking sleeve 15. Thus, the front sides of the left housing 12 and the right housing 13 can be locked by means of the pin 6, which is simple and convenient to operate.

[0033] Furthermore, the locking sleeve 15 and the receiving sleeve 14 are spaced apart vertically. The side wall of the locking sleeve 15 has a vertically penetrating opening through which the first bend 61 of the pin 6 can pass. The locking element also includes a spring 63. The lower end of the pin 6 has a second bend 62 extending to the bottom of the receiving sleeve 14. The spring 63 is sleeved on the lower end of the pin 6 and abuts against the receiving sleeve 14 and the second bend 62, thereby applying a downward force to the pin 6. By providing the spring 63, the frictional resistance when the first bend 61 abuts against the upper side of the locking sleeve 15 can be effectively increased, preventing the pin 6 from accidentally dislodging.

[0034] Of course, the left housing 12 and the right housing 13 can also be connected in other ways, such as designing the left housing 12 and the right housing 13 to be independent of each other, and connecting them by setting bolts on the left housing 12 and screw holes on the right housing 13.

[0035] In this embodiment, a hook 17 is provided on the upper side of the lubrication seat 1, so that a traction rope can be connected to the hook 17 from the outside, and the lubrication seat 1 can be raised by pulling the traction rope.
