Description

TECHNICAL FIELD

[0001] The utility model relates to oiler technical field, concretely is an oiler with old oil function of automatic recovery. BACKGROUND

[0002] Among numerous industrial equipment and mechanical systems, steel wire ropes play a crucial role. For example, in scenarios such as cranes, elevators, cable cars, and various material conveying equipment, steel wire ropes bear key functions such as carrying and traction. Taking cranes as an example, the frequent lifting operations have very high performance requirements for steel wire ropes. Ensuring good lubrication on the surface of steel wire ropes is a key factor in guaranteeing normal operation and prolonging service life.

[0003] Traditional steel wire rope lubrication methods have many drawbacks. On the one hand, during the lubrication operation, it is often difficult to achieve full and uniform coverage of the lubricating oil on the surface of the steel wire rope. For example, the stacker requires very strict full lubrication of the steel wire rope surface during the test running stage, but conventional oilers cannot guarantee that the lubricating oil effectively penetrates every part of the steel wire rope, especially the internal core part, resulting in poor lubrication effect, increased risk of steel wire rope wear, and reduced stability and safety of equipment operation.

[0004] On the other hand, the problem of old oil treatment has been plaguing the relevant industry. When the steel wire rope is used for a period of time, the original oil on the surface will mix with impurities, dust, and other pollutants, causing performance degradation and the need for timely replacement. However, old oil often drips or remains around the equipment, causing environmental pollution and potentially affecting other parts of the equipment. Moreover, if old oil accumulates in the steel wire rope cavity, it may seep out during equipment operation due to temperature changes and steel wire rope movement, potentially causing safety accidents, and it takes a lot of manpower and time to identify and clean up these hidden dangers.

[0005] In addition, existing oilers mostly only have a single oil injection function and lack a recycling mechanism for old oil, making it impossible to form a closed-loop management of lubrication operations. This not only hinders the effective use of resources but also makes equipment maintenance work complicated. Therefore, developing an oiler that can efficiently lubricate steel wire ropes and automatically recycle old oil has important practical significance and urgent needs, and it plays an important role in improving the overall performance of equipment, reducing maintenance costs, improving operational safety, and achieving environmental protection goals.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0034] Please refer to Figures 1-4 In the embodiments of the utility model, an oil injector with automatic old grease recovery function comprises:

[0035] Shell 1, the shell 1 inside is equipped with the channel 2 for steel wire rope to pass through;

[0036] Oil storage cavity 3, the oil storage cavity 3 is arranged in the shell 1, is used to store lubricating oil, and is communicated with the channel 2, so that the lubricating oil can act on the steel wire rope from the oil storage cavity 3;

[0037] Old grease recovery cavity 4, the old grease recovery cavity 4 is arranged in the shell 1, and is communicated with the channel 2, for collecting the old grease overflowed from the steel wire rope.

[0038] In the technical scheme of the utility model, the oil storage cavity 3 is arranged in the shell 1 and is communicated with the channel 2 for steel wire rope to pass through, when the steel wire rope passes through, it is just like soaking in the lubricating oil in the oil storage cavity 3, when the equipment runs, the steel wire rope continuously moves, and it produces dynamic contact with the lubricating oil, by virtue of the operation of the steel wire rope, the lubricating oil is uniformly distributed on the surface of the steel wire rope from the outer surface to the inner core, realizing all-round and deep lubrication, for example, in the process of frequent up and down running of the elevator, the steel wire rope always runs in the lubricating oil in the oil storage cavity 3, and constantly evenly applies the lubricating oil to itself, guaranteeing good lubrication state and continuously providing support for stable operation of the equipment;Or based on the fluidity and gravity of the liquid and other factors, the lubricating oil can gradually flow to the surface of the steel wire rope along the part where the oil storage cavity 3 contacts the steel wire rope, and with the movement of the steel wire rope in the equipment running, the lubricating oil is evenly covered on the surface of the steel wire rope under the action of friction, so that the comprehensive lubrication of the steel wire rope is realized, the friction loss of the steel wire rope during running is effectively reduced, and stable operation is ensured;

[0039] The old grease recovery cavity 4 is also arranged in the shell 1 and is communicated with the channel 2. During operation of the equipment, the original old grease on the surface of the steel wire rope will gradually lose viscosity and lubricating performance due to continuous operation, stress and environmental factors, and overflow from gaps and inter-strands of the steel wire rope. Since the recovery cavity is communicated with the channel 2, the overflowed old grease flows into the old grease recovery cavity 4 under the action of gravity, air flow and slight vibration generated during operation of the equipment, so that automatic collection of the old grease is realized, and the old grease is prevented from being scattered around the equipment; in some cases, such as when the moving speed of the steel wire rope is relatively high, the old grease recovery cavity 4 generates negative pressure, so that automatic recovery of the old grease is facilitated.

[0040] The oil injector innovatively integrates lubrication and old grease recovery functions, forms a complete lubrication operation closed-loop management system, fully meets the lubrication demand of the steel wire rope, reasonably recovers and processes the old grease, realizes effective utilization of resources, avoids adverse effects of overflow of the old grease on other components of the equipment, greatly simplifies the equipment maintenance work process and reduces maintenance cost compared with a traditional oil injector with only single oil injection function, and fully meets urgent requirements of modern industry for high efficiency, environmental protection and sustainable development, and provides a new and better solution for lubrication management of industrial equipment.

[0041] In the shell 1, a first isolation wall 5 for the oil storage cavity 3 and the old grease recovery cavity 4 is arranged, so that the oil storage cavity 3 and the old grease recovery cavity 4 are independent of each other.

[0042] The first isolation wall 5 arranged in the shell 1 physically separates the oil storage cavity 3 and the old grease recovery cavity 4 in structure, the first isolation wall 5 is designed to block a direct communication path between the oil storage cavity 3 and the old grease recovery cavity 4, and ensure that the two are independent in space; through the isolation design, the lubricating oil stored in the oil storage cavity 3 is not affected by impurities and pollutants that may exist in the old grease recovery cavity 4; in the same way, the old grease separated from the steel wire rope and collected in the old grease recovery cavity 4 is also limited in the old grease recovery cavity 4 and cannot flow reversely into the oil storage cavity 3, so that independent storage environments of the lubricating oil and the old grease are ensured.

[0043] Specifically, the first isolation wall 5 is provided with a first sealing ring 6 sleeved on the steel wire rope, and the first sealing ring 6 is located in the channel 2.

[0044] The design purpose is to further strengthen the isolation effect between the oil storage cavity 3 and the old grease recovery cavity 4, the first sealing ring 6 is made of fluororubber material, the fluororubber has excellent oil resistance, can effectively resist the erosion of lubricating oil and old grease, ensures that the performance is stable for a long time, meanwhile, it has high elasticity, can be closely surrounded around the steel wire rope, fills the gap between the steel wire rope and the first isolation wall 5, and the good high temperature resistance of the fluororubber enables it to maintain elasticity and sealing property in the high temperature environment generated by equipment operation; when the steel wire rope runs in the channel 2, the fluororubber first sealing ring 6 can adaptively adjust with the movement of the steel wire rope, and always maintains effective sealing of the gap; this design effectively prevents the lubricating oil from flowing from the oil storage cavity 3 into the old grease recovery cavity 4 through the gap between the steel wire rope and the isolation wall, and also prevents the pollutants in the old grease recovery cavity 4 from entering the oil storage cavity 3 in the opposite direction, further ensuring the independence and purity of the environments of the two cavities.

[0045] In the embodiment of the utility model, the first isolation wall 5 is further provided with a guide sleeve 7 sleeved on the steel wire rope, and the guide sleeve 7 is located in the channel 2.

[0046] The first sealing ring 6 is located on the side close to the oil storage cavity 3, the guide sleeve 7 is adjacent to the first sealing ring 6 and is located on the side close to the old grease recovery cavity 4.

[0047] The guide sleeve 7 is made of nano PTFE fluoropolymer, which has excellent wear resistance and can effectively cope with the frequent friction between the steel wire rope and the inner wall of the guide sleeve 7 when the steel wire rope moves at high speed, greatly prolonging the service life of the guide sleeve 7; its extremely low friction coefficient can significantly reduce the resistance of the steel wire rope when running in the channel 2, providing a smooth environment for the movement of the steel wire rope and ensuring the stability of the running track of the steel wire rope; at the same time, since the guide sleeve 7 is closely adjacent to the first sealing ring 6, it can to some extent share the lateral force from the steel wire rope borne by the first sealing ring 6, helping the first sealing ring 6 to better maintain close contact with the steel wire rope and further improve the sealing effect of the first sealing ring 6; in addition, the chemical stability of nano PTFE fluoropolymer is excellent, which can resist the erosion of complex chemicals in the old grease recovery cavity 4, and its smooth surface can prevent the attachment and accumulation of larger particle impurities that may appear in the old grease recovery cavity 4, avoiding the direct impact of impurities on the first sealing ring 6 and protecting the integrity of the first sealing ring 6, thereby ensuring the isolation effect between the oil storage cavity 3 and the old grease recovery cavity 4.

[0048] In the embodiment of the utility model, a plurality of old grease recovery cavities 4 are arranged along the direction in which the steel wire rope passes through the shell 1, and the plurality of old grease recovery cavities 4 are symmetrically distributed on both sides of the oil storage cavity 3, so that the oil storage cavity 3 is located in the middle position of the plurality of old grease recovery cavities 4.

[0049] During the operation of the device, old grease on the surface of the steel wire rope spills from different parts due to various factors, and the symmetrically distributed old grease recovery cavities 4 can collect the old grease spilled from the steel wire rope in all directions and in a balanced manner, thereby greatly improving the collection efficiency of the old grease; in addition, regardless of the movement of the steel wire rope, there is always a corresponding old grease recovery cavity 4 in a suitable position on both sides of the oil storage cavity 3 corresponding to the movement path of the steel wire rope, so that the old grease spilled from each part of the steel wire rope can be collected in a timely and effective manner.

[0050] In the embodiment of the utility model, the second isolation wall 8 is arranged in the shell 1 and acts on the adjacent old grease recovery cavities 4.

[0051] The second sealing ring 9 is arranged on the second isolation wall 8 and is sleeved on the steel wire rope and located in the channel 2.

[0052] The second isolation wall 8 is arranged in the shell 1 and acts on the adjacent old grease recovery cavities 4, which aims to effectively separate the old grease collected in different areas. Since the working conditions of the steel wire rope are different at different parts during the operation of the device, the composition and properties of the old grease are different. The second isolation wall 8 reduces the mutual mixing of the old grease in the adjacent recovery cavities through physical separation, maintains the relative simplicity of the properties of the old grease collected in each recovery cavity, and provides convenience for subsequent targeted treatment of the old grease.

[0053] The second sealing ring 9 is arranged on the second isolation wall 8 and is sleeved on the steel wire rope and located in the channel 2, which is to further strengthen the isolation effect. The second sealing ring 9 is made of a material with high elasticity and good oil resistance (such as nano PTFE fluoropolymer of the first sealing ring 6), tightly surrounds the steel wire rope, fills the gap between the steel wire rope and the second isolation wall 8, and self-adaptively adjusts with the movement of the steel wire rope when the steel wire rope runs in the channel 2, thereby always maintaining a good sealing state. This not only effectively prevents the old grease from penetrating through the gap between the steel wire rope and the wall between the adjacent old grease recovery cavities 4, prevents the mutual contamination of old grease with different properties, but also avoids the entry of external impurities into the recovery cavity, thereby ensuring the purity of the old grease recovery process.

[0054] In the embodiment of the utility model, the shell 1 is provided with an oil inlet 10 and an oil outlet 11, and the oil inlet 10 and the oil outlet 11 are in communication with the oil storage cavity 3.

[0055] The oil injection port 10 is connected with a high-pressure pump, when the equipment needs to be supplemented with lubricating oil, the high-pressure pump is started to inject the lubricating oil into the oil storage cavity 3 at a high speed through the oil injection port 10, the high-speed injected lubricating oil forms a negative pressure area in the oil storage cavity 3, which promotes the lubricating oil in the oil storage cavity 3 to be rapidly mixed and uniform, and further reduces the local pressure in the oil storage cavity 3, and accelerates the fusion of the new lubricating oil and the original lubricating oil in the cavity; the oil discharge port 11 is used to discharge the old lubricating oil in the oil storage cavity 3 when it is necessary to replace the lubricating oil or clean the oil storage cavity 3.

[0056] In the embodiment of the utility model, the shell 1 is divided into the upper shell 12 and the lower shell 13 which are detachably connected.

[0057] The internal oil storage cavity 3, the old grease recovery cavity 4, the first isolation wall 5, the second isolation wall 8 and various components thereon, such as the first sealing ring 6, the guide sleeve 7 and the second sealing ring 9, may need to be inspected, repaired or replaced due to long-term use, and by splitting the shell 1 into two parts, the internal structure can be directly exposed, greatly reducing the maintenance difficulty.

[0058] In the embodiment of the utility model, the shell 1 is provided with a visible window 14 at a position corresponding to the old grease recovery cavity 4.

[0059] Through the visible window 14, the equipment maintenance personnel can directly observe the liquid level height, color change and presence or absence of impurities of the old grease without disassembling the equipment, which helps the maintenance personnel to judge the equipment running state and whether the old grease recovery system is working normally according to the observed phenomena; for example, when the old grease liquid level in the old grease recovery cavity 4 is found to be abnormally high, it may indicate that the old grease overflow amount of the steel wire rope increases, and the wear condition of the steel wire rope needs to be further checked; if the old grease color is found to be abnormal or there are a large amount of impurities, it may indicate that the equipment running environment is poor or internal components have faults, affecting the normal recovery of the old grease.

[0060] In the embodiment of the utility model, the shell 1 is provided with a visible assembly at a position corresponding to the old grease recovery cavity 4, the visible assembly comprises a mounting frame 15 and a transparent piece 16 embedded in the mounting frame 15, the mounting frame 15 is detachably connected with the shell 1, and a sealing structure 17 is arranged between the mounting frame 15 and the shell 1 and between the mounting frame 15 and the transparent piece 16.

[0061] The mounting frame 15 and the transparent piece 16 cooperate to form the visible window 14.

[0062] The design of the visual assembly enables the equipment to maintain good operation state monitoring function in different working conditions and use environments, whether in harsh environments such as high temperature and high humidity, or in occasions with high requirements for equipment sealing, the sealing structure 17 can effectively play a role to guarantee the normal use of the visual window 14, and the detachable connection design facilitates flexible replacement of transparent pieces 16 of different specifications or materials according to actual needs to adapt to different observation needs and use conditions, thereby improving the adaptability and universality of the equipment.

[0063] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
