Abstract
Description
Technical Field
[0001] This invention relates to the field of lubrication technology, specifically to a lubrication station for irregularly shaped steel bars and its lubrication method. Background Technology
[0002] In the entire process of winding and armoring marine flexible hoses, in order to reduce the frictional resistance between irregularly shaped steel strips, prevent surface scratches, and ensure molding quality, it is usually necessary to continuously and uniformly lubricate the surface of the steel strips during winding.
[0003] Currently, the most common lubrication solution used in this industry is a fixed centralized lubrication station. These stations are typically located beside the equipment or on the foundation, using fixed pumping units, storage tanks, valve assemblies, and pipelines to deliver the lubricating medium to a relatively stationary distribution point on the equipment or an adjacent lubrication area. However, when dealing with irregularly shaped steel bar locking and armoring machines, the traditional fixed centralized lubrication station exhibits significant limitations.
[0004] Specifically, the core working components of the shaped steel bar locking and armoring machine typically require continuous or intermittent rotational motion during operation to spirally wind the shaped steel bars onto the core. However, the spray system of traditional fixed centralized lubrication stations struggles to keep pace with the rotational movement of the shaped steel bar winding point. This results in the nozzles failing to continuously and accurately align with the dynamically changing surface area of the shaped steel bar, leading to uneven lubrication coverage, wasted lubricating medium, or insufficient lubrication at critical friction points. Summary of the Invention
[0005] The purpose of this invention is to provide a lubrication station for irregularly shaped steel bars and its lubrication method, which solves the problem that the spray system of traditional fixed centralized lubrication stations is difficult to follow the rotational movement of the winding point of irregularly shaped steel bars, resulting in the nozzle being unable to continuously and accurately align with the dynamically changing surface area of the irregularly shaped steel bars, thus causing problems such as uneven lubrication coverage, waste of lubricating medium, or insufficient lubrication at key friction points.
[0006] The objective of this invention can be achieved through the following technical solutions: A special-shaped steel bar lubrication station is applied to a special-shaped steel bar locking and armoring machine.

The external storage station is used to replenish the medium in the buffer station, while the lubrication pipeline is responsible for delivering the lubricating medium in the buffer station to the spraying system. The nozzles in the spraying system correspond to the winding position of the shaped steel bars when the shaped steel bar locking and armoring machine is working. As the equipment rotates, it can continuously and accurately spray the lubricating medium onto the corresponding surface area of the shaped steel bars, effectively solving the problems of uneven lubrication coverage, waste of lubricating medium, or insufficient lubrication at key friction points in traditional lubrication methods.

Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0026] The inventors need to further elaborate on the research and development background of this application as follows: With the continuous deepening of marine oil and gas resource development and the increasing number of deep-sea scientific research activities, marine flexible hoses are playing an increasingly crucial role as an important transmission hub connecting seabed wellheads, offshore platforms and scientific research equipment.
[0027] The superior performance of marine flexible hoses relies on their multi-layered composite structure. Among these, the pressure-bearing armor layer, composed of high-strength steel strips spirally wound, is the core component that withstands internal and external pressures. The quality of its winding directly determines the hose's final mechanical properties and service life. Currently, this pressure-bearing armor layer is typically wound using a specialized armoring machine, continuously and tightly winding shaped steel strips at a specific angle onto a polymer inner tube that is moving at a uniform speed. Throughout the entire winding and armoring process, to reduce frictional resistance between the shaped steel strips, prevent surface scratches, and ensure forming quality, continuous and uniform lubrication of the steel strip surface is usually required during winding.
[0028] Currently, the most common lubrication solution used in this industry is a fixed centralized lubrication station. These stations are typically located beside equipment or on the foundation, using fixed pumping units, storage tanks, valve assemblies, and pipelines to deliver the lubricating medium to a relatively stationary distribution point on the equipment or an adjacent lubrication area. However, when dealing with shaped steel bar locking armoring machines (the shaped steel bar locking armoring machine used for processing marine flexible hoses can be a common armoring machine, or it can be the high-efficiency pressure-bearing shaped steel bar locking armoring machine previously applied for by the applicant with application number 2025114174990, such as...), Figures 4-5 As shown, the aforementioned armored machine requires rotational movement during operation, and traditional fixed centralized lubrication stations used for lubrication have revealed significant limitations.
[0029] Specifically, the core working components of the shaped steel bar locking and armoring machine (such as the winding disc and forming head) typically require continuous or intermittent rotation during operation to spirally wind the shaped steel bar onto the core. However, the spray system of traditional fixed centralized lubrication stations struggles to keep pace with the rotation of the shaped steel bar winding point, resulting in nozzles failing to continuously and accurately align with the dynamically changing surface area of the shaped steel bar. This leads to uneven lubrication coverage, wasted lubricating medium, or insufficient lubrication at critical friction points. (Even when the inventors directly mounted the end-effectors of the lubrication system (such as nozzles) onto the rotating components during development, a series of new technical challenges arose: First, the lubricating medium supply pipeline needs to connect the rotating and stationary parts. Traditional rigid pipelines or ordinary flexible hoses are difficult to operate under continuous rotation, easily leading to kinking, wear, or even breakage, posing a risk of leakage. Second, providing pressurized lubricating medium to the rotating components usually requires complex rotary joints, increasing system cost, complexity, and potential failure points.)
[0030] like Figures 1-3 As shown, an embodiment of the present invention provides a special-shaped steel bar lubrication station applied to a special-shaped steel bar locking and armoring machine, including a storage system, a pipeline system and a spraying system. The storage system is connected to the spraying system through the pipeline system. The storage system, pipeline system and spraying system rotate as the special-shaped steel bar locking and armoring machine operates to lubricate the special-shaped steel bar. The storage system includes a buffer station 5; the pipeline system includes an inlet / outlet pipeline 4 and a lubrication pipeline 7; the spraying system includes a nozzle 8; the buffer station 5 is connected to the inlet / outlet pipeline 4, the other end of the inlet / outlet pipeline 4 is connected to the lubrication pipeline 7, and the other end of the lubrication pipeline 7 is connected to the nozzle 8, the nozzle 8 corresponding to the shaped steel strip winding position when the shaped steel strip locking armor machine is working.
[0031] In this embodiment, the buffer station 5 in the storage system is used to store the lubricating medium. When the special-shaped steel bar buckle armoring machine stops, it can be pressurized and flushed with the lubricating medium to ensure a sufficient supply of lubricating medium. The inlet and outlet pipes 4 in the pipeline system are used for the medium transfer between the buffer station 5 and the external storage station 1. The external storage station 1 is used to replenish the medium to the buffer station 5, and the lubrication pipeline 7 is responsible for transporting the lubricating medium in the buffer station 5 to the spraying system. The nozzles 8 in the spraying system correspond to the special-shaped steel bar winding position when the special-shaped steel bar buckle armoring machine is working. As the equipment rotates, the nozzles can continuously and accurately spray the lubricating medium onto the corresponding special-shaped steel bar surface area, effectively solving the problems of uneven lubrication coverage, waste of lubricating medium, or insufficient lubrication at key friction points in traditional lubrication methods.
[0032] Furthermore, the buffer station 5 adopts an internally preset initial pressure technology. This preset initial pressure method can effectively avoid unnecessary impact and damage to the pipeline system and injection system caused by excessive pressure fluctuations, extend the service life of the entire lubrication station, and improve its operational stability and reliability. The lubrication pipeline 7 uses a flexible high-pressure hose, which is reasonably laid out and fixed along the rotation radius of the armored machine to avoid shaking or tangling during high-speed rotation. At the same time, a pulsation damper can be installed on the lubrication pipeline 7 to reduce pressure fluctuations caused by rotation and ensure that the lubricating medium is continuously and stably delivered to the nozzle 8.
[0033] Since the buffer station 5 has internal pressure in its initial state, when pressurizing and replenishing the lubricating medium, the external storage station 1 needs to provide a higher injection pressure. It should be understood that as the amount of lubricating medium injected increases, the internal pressure of the buffer station 5 will increase. Therefore, the external injection pressure needs to be greater than the internal pressure when the storage capacity is set. At the same time, the internal pressure of the buffer station 5 can be preset according to the actual required storage space to adapt to different lubrication needs.
[0034] Furthermore, in this embodiment, lubricating medium can be replenished via an external storage station 1 without disassembling the buffer station 5. Specifically, the external storage station 1 is simply connected to the buffer station 5 via inlet / outlet pipes 4, and the delivery pump of the external storage station 1 is started to safely and efficiently deliver the lubricating medium to the buffer station 5. This design greatly improves the convenience and efficiency of lubricating medium replenishment, reducing downtime and maintenance costs caused by disassembling the buffer station 5. Moreover, the output pipe 2 and the inlet / outlet pipes 4 are connected quickly using a quick-connect structure, enabling rapid replenishment of the buffer station 5. This quick-connect structure eliminates the need for complex operating procedures when replenishing lubricating medium, significantly saving time and labor costs.
[0035] Furthermore, the aforementioned quick-connect structure can employ a rotary quick-change connector with a self-sealing function, which automatically opens the flow path when connected and closes bidirectionally when disconnected, preventing lubricant leakage and air ingress. It also accommodates residual attitude deviations that may exist in rotating components after shutdown, thereby improving connection reliability.
[0036] Meanwhile, since the entire lubrication station system (including the storage system, pipeline system, and spray system) is installed on the rotating parts of the special-shaped steel bar locking armor machine, it can rotate with the operation of the special-shaped steel bar locking armor machine. Therefore, there is no need to worry about problems such as kinking, wear, or breakage of the pipeline during rotation, which effectively avoids leakage of lubricating medium and improves the stability and reliability of the system.
[0037] The rotary lubrication scheme in this embodiment can also be extended to other industrial equipment that requires fixed-point lubrication while rotating, demonstrating high versatility and adaptability.
[0038] Preferably, the buffer station 5 includes a media storage device, and at least two sets of the media storage device are provided. Multiple sets of the media storage device are fixedly installed on the special-shaped steel bar buckle armoring machine, and the multiple sets of the media storage device are symmetrically distributed about the rotation center axis of the special-shaped steel bar buckle armoring machine.
[0039] In this embodiment, the setting of multiple media storage devices can, on the one hand, increase the storage capacity of lubricating media to meet the needs of the special-shaped steel bar locking armor machine for long-term continuous operation, reduce downtime caused by frequent replenishment of lubricating media, and improve production efficiency; on the other hand, it can adapt to the point-to-point lubrication requirements of winding different special-shaped steel bars (C-type, T-type, K-type, etc.).
[0040] Furthermore, the symmetrical distribution of multiple media storage units around the rotating center axis of the irregular steel bar locking armor machine ensures that the entire storage system maintains good balance during rotation, reduces vibration and eccentric force caused by uneven mass distribution, minimizes the impact on the overall operational stability of the equipment, and also reduces wear on rotating parts, extending the service life of the equipment.
[0041] Preferably, the internal pressure of the medium storage is preset to be 0.8MPa-1.0MPa.
[0042] In this embodiment, by utilizing the preset internal pressure, the internal lubricating medium can be completely discharged at the end of the lubrication process (i.e., when there is little lubricating medium in the medium storage tank), preventing residue and solidification. Furthermore, controlling the internal pressure within the range of 0.8MPa to 1.0MPa has been verified through extensive experiments and practice. This ensures that the lubrication requirements are met (the flow rate of nozzle 8 is 2L / h; due to the viscosity of the lubricating medium, the flow rate should not be too fast or too slow) without causing additional load to the equipment components due to excessive pressure, effectively balancing the lubrication effect with the safe and stable operation of the equipment.
[0043] Preferably, the media storage device is provided with an air bladder, and the internal pressure of the media storage device is adjusted by injecting nitrogen gas into the air bladder.
[0044] In this embodiment, the airbag not only facilitates precise adjustment of the internal pressure but also buffers pressure fluctuations within the media storage device to a certain extent, ensuring internal pressure stability. Nitrogen, as an inert gas, is chemically stable and will not react chemically with the lubricating medium, thus avoiding any impact on the lubricating medium's performance and ensuring reliable lubrication. Furthermore, using nitrogen to regulate internal pressure offers the advantage of high safety, reducing safety hazards caused by the instability of the gas's properties.
[0045] Furthermore, the airbag and nitrogen combination system can more proactively and precisely maintain or adjust the system working pressure, unaffected by slight changes in the lubricating medium level, and can effectively buffer pressure pulsations caused by rotation, temperature changes or injection, ensuring that the injection pressure of nozzle 8 is constant.
[0046] Preferably, this embodiment further includes an external storage station 1, which is connected to an output pipeline 2, and the inlet / outlet pipeline 4 is connected to an input pipeline 3, which is connected to the output pipeline 2; the external storage station 1 is used to replenish the medium for the cache station 5.
[0047] In this embodiment, the use of external storage station 1 enables the replenishment of lubricating medium without disassembling cache station 5, which greatly improves the convenience and efficiency of lubricating medium replenishment and reduces downtime and maintenance costs caused by disassembling cache station 5.
[0048] Preferably, a gear metering pump assembly 6 is provided between the lubrication pipeline 7 and the inlet / outlet pipeline 4, and the gear metering pump assembly 6 is used to control the flow rate of the medium flowing into the lubrication pipeline 7.
[0049] In this embodiment, the gear metering pump unit 6 is existing technology and can be of the JRG1X2.4CC type. The gear metering pump unit 6 achieves a stable output of viscous lubricating media, avoiding output instability caused by the lubricating media's inherent physical properties (viscosity). This ensures that the lubricating media can be delivered to the lubrication pipeline 7 at a stable and appropriate flow rate, and then precisely sprayed onto the surface of the irregularly shaped steel strip through the nozzle 8, meeting the precise lubrication flow rate requirements of different winding processes. Furthermore, this gear metering pump unit 6 has high metering accuracy and reliability, maintaining stable performance during long-term operation, reducing the adverse effects of flow rate fluctuations on lubrication, and improving the overall working quality and stability of the lubrication station.
[0050] Preferably, the gear metering pump assembly 6 includes a motor and a bulk pump, wherein the speed ratio of the motor to the bulk pump is 1:(50-55).
[0051] In this embodiment, the motor typically operates at a high speed to achieve efficient power output. The 1:(50-55) transmission ratio configuration enables the bulk pump to smoothly deliver fluid, establish stable pressure, and prevent wear and cavitation.
[0052] Preferably, a pressure gauge 9 is provided in the input pipeline 3, and the pressure gauge 9 is located in the middle of the connecting pipeline between the input pipeline 3 and the inlet / outlet pipeline 4.
[0053] In this embodiment, a pressure gauge 9 is added to display the pressure injected from the external storage station 1 into the buffer station 5, so that the operator can monitor the injection pressure in real time. When the pressure exceeds the preset threshold, measures can be taken in time to adjust it, ensuring the stability and safety of the injection process and avoiding the impact of abnormal pressure on the storage of lubricating medium in the buffer station 5 and subsequent normal lubrication work.
[0054] Furthermore, pressure gauge 9 can be connected to a controller (such as a PLC controller) to achieve intelligent control.
[0055] Preferably, the lubrication pipeline 7 is arranged along the axial direction of the special-shaped steel bar locking armor machine, and multiple sets of branches are provided on the side of the lubrication pipeline 7 away from the buffer station 5. Multiple sets of nozzles 8 are provided, and the multiple sets of nozzles 8 correspond one-to-one with the multiple sets of branches.
[0056] In this embodiment, nozzle 8 can be an adjustable-angle and adjustable-flow nozzle. By adjusting the spray angle and flow rate on-site, it can adapt to the lubrication requirements of different specifications of special-shaped steel bars and different winding processes, further improving lubrication accuracy and media utilization. While ensuring winding quality, it reduces the consumption of lubricating media and the impact on the environment. Furthermore, the nozzles 8 on each branch can be independently controlled, precisely adjusting the flow rate and angle of the lubricating media according to the actual needs of different parts of the special-shaped steel bar locking and armoring machine. This ensures that every location requiring lubrication receives sufficient and appropriate lubrication, effectively improving the lubrication effect, reducing equipment wear and malfunctions caused by uneven lubrication, and extending the service life of the special-shaped steel bar locking and armoring machine.
[0057] Preferably, a lubrication method for a special-shaped steel bar lubrication station, using the above-mentioned special-shaped steel bar lubrication station, includes the following steps: When the special-shaped steel bar locking armoring machine is stopped, connect the output pipe 2 of the external storage station 1 to the input pipe 3 using a quick connector. Pressurize the buffer station 5 with lubricating medium through the delivery pump on the external storage station 1 and monitor it with pressure gauge 9. After the lubricating medium injection is completed, disconnect the quick connector and fix the input pipe 3 on the armoring machine. When the shaped steel bar locking armor machine is working, the entire lubrication station system (including the buffer station 5 in the storage system, the inlet and outlet pipes 4 and lubrication pipes 7 in the pipeline system, and the nozzles 8 in the spraying system) will rotate. The flow rate of the lubricating medium flowing into the lubrication pipe 7 is controlled by the gear metering pump group 6, and then sprayed onto the outer surface of the wound shaped steel bar through the nozzles 8 at a set angle and flow rate.
[0058] The nozzle 8 corresponds to the winding point of each group of irregular steel strips. After being sprayed on the surface of the irregular steel strips, it is evenly flattened on the surface of the irregular steel strips by the pressure roller at the winding disc of the armoring machine.
[0059] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
