Description

Technical Field

[0001] The invention belongs to the field of stacker oilers, and in particular relates to a used grease recovery bin. Background Art

[0002] In the field of modern industrial warehousing, stacker cranes, as key equipment in automated warehousing systems, are responsible for the storage and handling of goods. Their efficient and stable operation is crucial to the operation of the entire warehousing system. The lubrication system of the stacker crane, as a key subsystem to ensure its normal operation, directly affects the service life, operating efficiency and maintenance cost of the equipment.

[0003] At present, although some existing automatic lubrication systems have improved the degree of automation of lubrication to a certain extent, there are still some problems. For example, during the lubrication process, oil leakage from the oiler is relatively common. This is because during the test and running-in process of the stacker, the surface of the wire rope is required to be fully lubricated with oil, but the capacity of the old oil recovery bin in the original design is too small. When the wire rope cavity is full of oil, it is easy to have the hidden danger of oil leakage. Oil leakage will not only cause waste of grease, but may also pollute the storage environment and affect the quality and safety of the goods. At the same time, for the recycling and treatment of old grease, traditional systems often lack effective measures and cannot realize the automatic recycling and reuse of old grease, resulting in waste of resources and environmental pollution. Summary of the invention

[0004] The purpose of the present invention is to address the shortcomings of the existing old grease recovery bin proposed in the above background technology, especially when the wire rope cavity is full of oil, oil leakage is likely to occur. The oil leakage will not only cause waste of grease, but also pollute the storage environment and affect the quality and safety of the goods. At the same time, for the recycling of old grease, traditional systems often lack effective measures and cannot realize the automatic recovery and reuse of old grease, resulting in waste of resources and environmental pollution.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a used grease recovery bin, including an oiler body and an oil guide mechanism, the oiler body including a bottom shell and a top shell, an oil inlet bin, two first used grease recovery bins and two second used grease recovery bins are arranged between the bottom shell and the top shell, a negative pressure mechanism is arranged below the bottom shell, wherein the oil inlet bin is located between the two first used grease recovery bins, the two first used grease recovery bins are located between the two second used grease recovery bins, and the three bin bodies are interconnected, a first sealing ring is installed between the oil inlet bin and the two first used grease recovery bins, a second sealing ring is installed on both side walls of the two second used grease recovery bins, drainage tubes are installed at both ends of the negative pressure mechanism, the two drainage tubes are installed at the bottom of the bottom shell, and the drainage tubes are connected to the corresponding second old grease recovery bin internal space.

[0006] Furthermore, two wire rope guide sleeves are installed between the bottom shell and the top shell, and the wire rope guide sleeves are located between the first used grease recovery bin and the first sealing ring.

[0007] Furthermore, the wire rope guide sleeve is made of nano-PTFE fluoropolymer material to reduce friction loss between the wire rope and the guide sleeve.

[0008] Furthermore, two visible transparent window panels are installed on the top of the top shell, and the two visible transparent window panels correspond to the positions of the first used grease recovery bin and the second used grease recovery bin.

[0009] Furthermore, the oil guide mechanism is detachably connected to the top shell, and a pressure detection mechanism is installed on the oil guide mechanism to monitor the oil pressure inside the oil guide mechanism and the oil inlet bin.

[0010] Furthermore, a grease filter housing is installed at one end of the oil guide mechanism, an inner filter cover is installed in the grease filter housing, the inner filter cover is composed of a filter cylinder and a filter hemisphere, a storage box is installed at the bottom of the grease filter housing, and a baffle is detachably connected to the bottom of the storage box.

[0012] Furthermore, a support rod for supporting and reinforcing the rotating rod is installed on the inner side of the grease filter housing, and the rotating rod is rotatably connected to the inner wall of the support rod.

[0013] Compared with the existing technology, the advantages of this old grease recovery bin are:

[0014] 1. The present invention uses the pressure increased by the first old grease recovery bin and the internal booster device to allow the grease to fully penetrate and wrap the wire rope to achieve sufficient lubrication. The negative pressure mechanism is connected to the old grease recovery bottle on the base of the stacker through the drainage tube, so that a negative pressure environment is formed inside the second old grease recovery bin. Excess grease will flow continuously into the old grease recovery bottle along the drainage tube and the catheter under the attraction of the negative pressure for collection.

DETAILED DESCRIPTION

[0022] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0023] The waste grease recovery bin according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the used grease recovery bin of the embodiment of the present invention may include an oiler body 1 and an oil guide mechanism 2, the oiler body 1 includes a bottom shell 11 and a top shell 12, an oil inlet bin 13, two first used grease recovery bins 14 and two second used grease recovery bins 15 are arranged between the bottom shell 11 and the top shell 12, and a negative pressure mechanism 4 is arranged below the bottom shell 11.

[0025] The oil inlet bin 13 is located between the two first used grease recovery bins 14, the two first used grease recovery bins 14 are located between the two second used grease recovery bins 15, and the three bins are interconnected.

[0026] It should be noted that the steel wire rope described in this embodiment passes through the bottom shell 11 and the top shell 12, and a booster device is provided in the first waste grease recovery bin 14.

[0027] A first sealing ring 16 is installed between the oil inlet bin 13 and the two first used grease recovery bins 14 , and a second sealing ring 17 is installed on both side walls of the two second used grease recovery bins 15 .

[0028] It should be noted that the first sealing ring 16 and the second sealing ring 17 described in this embodiment are both made of open-type fluororubber material, wherein the two second sealing rings 17 are located at the end positions of the bottom shell 11 and the top shell 12 .

[0029] Drainage pipes 41 are installed at both ends of the negative pressure mechanism 4 . The two drainage pipes 41 are installed at the bottom of the bottom shell 11 , and the drainage pipes 41 are connected to the internal space of the corresponding second waste grease recovery bin 15 .

[0030] It should be noted that the negative pressure mechanism 4 described in this embodiment is connected to the old grease recovery bottle installed on the stacker base through a bottom conduit.

[0031] Specifically, when the automatic lubrication system of the stacker is running, the high-pressure pressure pump releases grease into the oil inlet bin 13 through the oil guide mechanism 2. After the grease lubricates the wire rope, the excess grease will flow through the oil inlet bin 13 and the first old grease recovery bin 14 to the second old grease recovery bin 15 under the action of gravity and system pressure, so as to achieve the preliminary collection of the old grease. In the first old grease recovery bin 14, the pressure increased by the internal booster device allows the grease to fully penetrate and wrap the wire rope to achieve full lubrication. A first sealing ring 16 is installed between the oil inlet bin 13 and the two first old grease recovery bins 14, which can play a sealing role to prevent grease leakage and ensure that the grease can flow according to the designed path. Second sealing rings 17 are installed on both side walls of the two second old grease recovery bins 15 to further enhance the sealing effect and prevent external impurities from entering the recovery bin to affect grease recovery and grease To prevent leakage, drainage pipes 41 are installed at both ends of the negative pressure mechanism 4. The drainage pipes 41 are installed at the bottom of the bottom shell 11 and are connected to the corresponding internal space of the second old grease recovery bin 15. The negative pressure mechanism 4 is connected to the old grease recovery bottle on the base of the stacker through the drainage pipe 41, so that a negative pressure environment is formed inside the second old grease recovery bin 15. Excess grease will flow into the old grease recovery bottle continuously along the drainage pipe 41 and the catheter under the attraction of negative pressure and be collected. This automatic recovery process can effectively collect the old grease and solve the safety hazards of oil dripping and oil seepage during normal operation of the stacker, so that the high-pressure pressure pump can extract it and put it into lubrication work again to achieve recycling. After the optimized design of the oiler, there is no need to worry about the problem of old oil leakage, and no manual intervention and wiping maintenance are required. Long-term safe, stable and automatic lubrication is achieved. The old grease is automatically recovered to the base of the stacker and an old grease recovery bottle is set to achieve a long-term maintenance-free solution.

[0032] In one embodiment of the present invention, Figure 1-Figure 5 As shown, two wire rope guide sleeves 18 are installed between the bottom shell 11 and the top shell 12 , and the wire rope guide sleeves 18 are located between the corresponding first old grease recovery bin 14 and the first sealing ring 16 .

[0033] It should be noted that the axial positions of the two wire rope guide sleeves 18 described in this embodiment correspond to each other, and the steel wire passes through the middle apertures of the two wire rope guide sleeves 18 .

[0034] Specifically, when the steel wire rope passes through the bottom shell 11 and the top shell 12 for lubrication operation, the steel wire rope guide sleeve 18 can guide the steel wire rope, so that the steel wire rope remains stable during movement and avoids unnecessary friction or collision with other parts of the recovery bin. Moreover, the steel wire rope guide sleeve 18 is located between the first old grease recovery bin 14 and the first sealing ring 16, which can block the splash of grease to a certain extent, ensuring that the grease flows into the first old grease recovery bin 14 in a more orderly manner, thereby improving the grease recovery efficiency.

[0035] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the wire rope guide sleeve 18 is made of nano-PTFE fluoropolymer material to reduce the friction loss between the wire rope and the wire rope.

[0036] Specifically, the wire rope guide sleeve 18 is made of nano-PTFE fluoropolymer material, which has the characteristic of low friction coefficient. During the operation of the wire rope, the friction loss between the wire rope guide sleeve 18 and the wire rope is significantly reduced. On the one hand, the wear on the surface of the wire rope is reduced, and the service life of the wire rope is extended; on the other hand, the heat generated by friction is reduced, and the degradation of grease performance due to overheating is avoided, thereby ensuring the stability of the lubrication system and improving the overall operation effect of the old grease recovery bin.

[0037] In one embodiment of the present invention, Figure 1-Figure 5 As shown, two visible transparent window panels 19 are installed on the top of the top shell 12 , and the two visible transparent window panels 19 correspond to the positions of the first old grease recovery bin 14 and the second old grease recovery bin 15 .

[0038] It should be noted that the visible transparent window plate 19 described in this embodiment enables the adjacent first used grease recovery bin 14 and the second used grease recovery bin 15 to be visualized at the same time.

[0039] Specifically, the recovery of old grease in the first old grease recovery bin 14 and the second old grease recovery bin 15, such as the liquid level of the grease, the color of the grease and the impurities, can be directly observed through the visible transparent window panel 19. The operator can judge in time whether the recovery bin needs to be cleaned or whether there is an abnormal problem in grease recovery based on the observed information, so as to take corresponding measures in time to ensure the normal operation of the old grease recovery bin.

[0040] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the oil guide mechanism 2 is detachably connected to the top shell 12 , and a pressure detection mechanism 21 is installed on the oil guide mechanism 2 to monitor the internal oil pressure of the oil guide mechanism 2 and the oil inlet tank 13 .

[0041] Specifically, during the operation of the lubrication system, oil pressure is an important parameter. The pressure detection mechanism 21 monitors the oil pressure in real time. When the oil pressure rises or falls abnormally, it may mean that there are blockages, leakages and other faults in the lubrication system. Through the oil pressure information fed back by the pressure detection mechanism 21, the operator can promptly discover the problem and conduct investigations and repairs to ensure the normal operation of the lubrication system and the old grease recovery bin.

[0042] In one embodiment of the present invention, Figure 1-Figure 5As shown, a grease filter housing 3 is installed at one end of the oil guide mechanism 2, an inner filter cover 31 is installed in the grease filter housing 3, the inner filter cover 31 is composed of a filter cylinder and a filter hemisphere, a storage box 32 is installed at the bottom of the grease filter housing 3, and a baffle 321 is detachably connected to the bottom of the storage box 32.

[0043] It should be noted that the oil guide mechanism 2 described in this embodiment is connected to the oil delivery pipeline of the high-pressure pressure pump through the grease filter housing 3.

[0044] Specifically, the grease conducted from the high-pressure pressure pump to the oil guide mechanism 2 will flow into the grease filter housing 3, and the grease will be filtered by the inner filter cover 31. The filter cylinder and the filter hemisphere can effectively intercept impurities in the grease, such as metal debris, dust particles, etc. A storage box 32 is installed at the bottom of the grease filter housing 3, and a baffle 321 can be detachably connected to the bottom of the storage box 32. When the impurities filtered by the inner filter cover 31 accumulate to a certain extent, the baffle 321 can be removed to clean the impurities in the storage box 32, thereby ensuring the filtering effect of the inner filter cover 31 and preventing impurities from entering the subsequent recovery bin and lubrication system to affect the normal operation of the equipment.

[0045] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the inner wall of the inner filter cover 31 is rotatably connected to a rotating rod 33, one end of the rotating rod 33 is equipped with a plurality of rotating cleaning frames 34, and the other end of the rotating rod 33 is equipped with a plurality of liquid-driven blades 35. The plurality of rotating cleaning frames 34 are rotatably connected to the outer side of the inner filter cover 31, and the liquid-driven blades 35 are not in contact with the grease filter housing 3 and the inner filter cover 31.

[0046] It should be noted that the rotating cleaning frame 34 described in this embodiment is adapted to the outer shape of the inner filter cover 31, so as to achieve close scraping cleaning.

[0047] Specifically, when grease flows in the inner filter cover 31, the impact force of the grease will drive the rotating rod 33 to rotate. During the rotation of the rotating rod 33, the rotating cleaning frame 34 will rotate accordingly to clean the outside of the inner filter cover 31 to prevent impurities from adhering to the outer wall of the inner filter cover 31 and affecting the filtering effect; the liquid drive blades 35 do not contact the grease filter housing 3 and the inner filter cover 31, thereby avoiding mutual interference.

[0048] In one embodiment of the present invention, Figure 1-Figure 5 As shown, a support rod 36 for supporting and reinforcing the rotating rod 33 is installed on the inner side of the grease filter housing 3 , and the rotating rod 33 is rotatably connected to the inner wall of the support rod 36 .

[0049] Specifically, the support rod 36 provides a stable support structure for the rotating rod 33. When the rotating rod 33 rotates under the impact force of grease, the support rod 36 can prevent the rotating rod 33 from shaking or deflecting, thereby ensuring the stability of the rotation axis of the rotating rod 33. This helps the rotating cleaning frame 34 to better clean the outside of the inner filter cover 31, while also extending the service life of the rotating rod 33 and its related components, and improving the working reliability of the grease filter.

[0050] In summary, the old grease recovery bin of the embodiment of the present invention solves the problem of oil leakage after the wire rope cavity is full of oil in the prior art. By using the first old grease recovery bin 14 and the pressure increased by the internal booster device, the grease fully penetrates and wraps the wire rope to achieve full lubrication. The negative pressure mechanism 4 is connected to the old grease recovery bottle on the stacker base through the drainage pipe 41, so that a negative pressure environment is formed inside the second old grease recovery bin 15. Excess grease will flow into the old grease recovery bottle continuously along the drainage pipe 41 and the catheter under the attraction of negative pressure for collection. This automatic recovery process can effectively collect old grease and solve the safety hazards of oil dripping and oil leakage during normal operation of the stacker.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
