Description

Technical Field

[0001] The utility model relates to the field of pipe lubrication equipment, in particular to a grease accumulation prevention device. Background Art

[0002] To prevent corrosion, lubricate, and extend service life, many pipe fittings require lubrication on their inner surfaces, which can be accomplished by applying grease to the inner surface of the pipe. However, since many pipe fittings are relatively slender, direct oiling is difficult. To improve production efficiency, pipe inner wall lubrication equipment has emerged, which can quickly and evenly apply grease to the inner wall of the pipe.

[0003] like Figure 9 As shown, an existing lubrication device includes a machine and an oiling portion 11 on the machine, the pipe 2 to be lubricated is sleeved on the oiling portion 11, and the bottom end of the pipe 2 to be lubricated is in contact with the table 1 of the machine; the oiling portion 11 can extend into the interior of the pipe 2 to be lubricated for lubrication; specifically, an oil outlet is provided on the oiling portion 11, and an oil pipeline is connected to the bottom end of the oiling portion, and an oiling piece is provided on the oiling portion 11. During lubrication, the oiling portion 11 rises to the top of the pipe 2 to be lubricated, and then the oil outlet starts to discharge oil, so that the grease forms an adherent oil layer on the inner wall of the pipe 2 to be lubricated, and at this time the oiling portion 11 starts to descend toward the bottom end of the pipe 2 to be lubricated, and at the same time the oiling piece evenly spreads the adherent oil layer on the inner wall of the pipe 2 to be lubricated to form a lubricating oil layer 2a; however, this device has certain problems.

[0004] When the greasing portion 11 moves to the bottom end of the pipe to be lubricated 2, the oil outlet stops discharging oil. Since the opening at the bottom end of the pipe to be lubricated 2 is in contact with the table 1, accumulated grease 2b that is difficult to discharge will be formed at the bottom end of the pipe to be lubricated 2. As a result, after the pipe to be lubricated 2 is lubricated, the accumulated grease 2b needs to be manually cleaned.

[0005] When manually cleaning the accumulated grease 2b, it is difficult to maintain the uniformity of the grease on the inner wall of the lubricated pipe 2, and it is easy to destroy the lubricating oil layer 2a in the uniform position; affecting the performance of the lubricated pipe 2. At the same time, for the lubricated pipes 2 to be lubricated after large quantities of lubrication, the efficiency of manual cleaning is low, affecting the subsequent use process of the lubricated pipes 2 to be lubricated. Summary of the Invention

[0006] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a grease accumulation prevention device, which arranges a gasket between the table top of the machine and the bottom end of the pipe to be lubricated, so that the oiling part can apply grease to the pipe wall downward while the oiling part passes through the junction position of the gasket and the pipe to be lubricated and retracts downward into the gasket, and scrapes excess grease into the gasket, thereby avoiding grease accumulation at the bottom end opening of the pipe to be lubricated, eliminating the manual cleaning process of the pipe to be lubricated, ensuring the lubrication effect of the pipe to be lubricated, and making the pipe to be lubricated can be lubricated in place at one time, thereby improving the lubrication efficiency of the pipe to be lubricated.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A grease accumulation prevention device, comprising:

[0009] The machine table is provided with an oiling part that can be extended up and down;

[0010] The washer tube is matched with the cross-sectional shape and diameter of the pipe to be lubricated; the lower end of the washer tube is supported on the table, and the upper end of the washer tube is used to support the pipe to be lubricated; and the position of the washer tube corresponds to the position of the oiling part;

[0011] The device has an initial state and a working state. In the initial state, the oiling part is located close to the table top and in the enclosed space of the pad tube. When the device switches from the initial state to the working state, the oiling part can extend upward from the pad tube. When the device switches from the working state back to the initial state, the oiling part retracts and crosses the supporting end of the pad tube and returns to the enclosed space of the pad tube, and the top end of the oiling part retracted into the pad tube is not higher than the supporting end of the pad tube.

[0012] Preferably, a positioning seat is provided on the table, which can fix the position of the pipes to be lubricated and the gaskets; after the position is fixed, the state of the pipes to be lubricated and the gaskets is more stable, and there will be no offset or misalignment.

[0013] Preferably, the positioning seat is provided with a positioning hole that matches the outer diameter and cross-sectional shape of the gasket tube, and the positioning hole passes through the positioning seat; the gasket tube is in the positioning hole, and the supporting end of the gasket tube passes through the positioning hole and rests against the bottom end of the pipe to be lubricated, and the top of the positioning seat is provided with a plurality of protrusions arranged around the positioning hole, the inner side surface of the protrusion matches the outer wall surface of the gasket tube, and the height of the protrusion is greater than the height of the supporting end of the gasket tube; the inner side surface of the protrusion is in close contact with the outer wall of the pipe to be lubricated and the outer wall of the gasket tube to fix the position of the pipe to be lubricated and the gasket tube to avoid misalignment of the pipe to be lubricated and the gasket tube.

[0014] Preferably, the positioning seat is provided with a positioning hole that matches the outer diameter and cross-sectional shape of the gasket tube, and the positioning hole passes through the positioning seat; the pipe to be lubricated and the gasket tube are located in the positioning hole and are tightly attached to the inner wall of the positioning hole; the positioning hole forms an embracing effect on the pipe to be lubricated and the gasket tube that are against each other, thereby avoiding misalignment of the pipe to be lubricated and the gasket tube.

[0015] Preferably, at least one oil drain port is provided at a position of the gasket tube close to the table top, and an avoidance notch corresponding to the position of the oil drain port is provided on the positioning seat, and the avoidance notch is communicated with the positioning hole; so that excess grease scraped into the gasket tube can be discharged through the oil drain port and the avoidance notch, thereby avoiding excessive accumulation of grease in the gasket tube.

[0016] Preferably, the positioning seat is detachably fixed to the table; the detachable design allows the positioning seat to be removed from the table after lubrication of the lubricated pipe fittings is completed, so as to facilitate centralized cleaning of excess grease.

[0017] Preferably, a plurality of screw holes are provided on the table top, and a through hole corresponding to the position of the screw hole is provided on the positioning seat. The screws are passed through the through holes and screwed into the screw holes to fix the positioning seat on the table top. The screw connection method has a good connection effect, so that the positioning seat can form a stable positioning effect for the lubricated pipe fittings and the gasket pipe, and the screws are also easy to remove, so that the positioning seat can be quickly removed from the table top.

[0018] Preferably, the positioning seat is made of nylon or plastic; nylon or plastic has low hardness, which can avoid damage when the lubricated pipe collides with the positioning seat during assembly and disassembly.

[0019] Preferably, the length of the gasket is in the range of 20mm-80mm; a gasket of reasonable length can raise the pipe to be lubricated, and can ensure that the retracted oiling portion can completely return to the gasket, so that the lubricating oil layer on the inner wall of the pipe to be lubricated is more uniform.

[0020] The utility model provides a device for preventing grease accumulation, which has the following advantages compared with the prior art:

[0021] 1. Since the gasket separates the bottom of the pipe to be lubricated from the table of the machine, it makes room for the downward-retracted oiling part, so that the oiling part can lubricate the pipe to be lubricated at one time and scrape the excess grease into the gasket, eliminating the need for manual cleaning of excess grease and not damaging the lubricating oil layer formed on the inner wall of the pipe, thus ensuring the lubrication effect of the pipe.

[0022] 2. Since the process of manually cleaning excess grease is omitted, the lubrication efficiency of the lubricated pipe fittings is improved, ensuring the subsequent use of the lubricated pipe fittings.

[0023] 3. The oil drain port on the gasket and the avoidance notch on the positioning seat can allow the excess grease scraped into the gasket to be discharged and cleaned separately, avoiding excessive accumulation of excess grease in the gasket.

[0024] 4. Excess grease discharged through the oil drain port and the avoidance gap will adhere to the table top. Since the positioning seat and the table top are detachably connected, the positioning seat can be removed from the table top to facilitate manual centralized cleaning of the grease attached to the table top to ensure the cleanliness of the table top.

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figure 1-8 As shown, the present invention has multiple implementation modes, and the specific implementation modes are as follows:

[0038] Example 1: Figure 1-7 As shown, the utility model provides a grease accumulation prevention device, which can evenly apply grease to the inner wall of the lubricated pipe 2 while preventing excess grease from accumulating at the opening of the lubricated pipe 2. The lubricated pipe 2 is usually a steel pipe, and the cross-sectional shape of the lubricated pipe 2 can be circular or square. The device includes:

[0039] The machine platform has a table 1 on which an oiling portion 11 that can be extended and retracted upward and downward is provided. Specifically, the bottom end of the oiling portion 11 is connected to an oil delivery pipe, and the oil delivery pipe is connected to a power mechanism that drives the oil delivery pipe to move up and down. The oiling portion 11 is provided with corresponding oil outlets and oiling members. The oiling members have various structures and can be an oiling ring that is sleeved on the oiling portion 11 and contacts the inner wall of the pipe 2 to be lubricated, or a rotating roller that is rotatably connected to the side wall of the oiling portion 11 and contacts the inner wall of the pipe 2 to be lubricated.

[0040] The washer tube 4 is matched with the cross-sectional shape and diameter of the pipe 2 to be lubricated; the lower end of the washer tube 4 is supported on the table 1, and the upper end of the washer tube 4 is used to support the pipe 2 to be lubricated; the device is also provided with a pressure plate for pressing the top of the pipe 2 to be lubricated so that the bottom end of the pipe 2 to be lubricated is tightly against the supporting end of the washer tube 2; and the position of the washer tube 4 corresponds to the position of the greasing part 11;

[0041] The device has an initial state and a working state. In the initial state, the oiling part 11 is located near the table 1 and in the enclosed space of the gasket tube 4; when the device switches from the initial state to the working state, the oiling part 11 can extend upward from the gasket tube 4; thereby forming a uniform lubricating oil layer 2b on the inner wall of the pipe 2 to be lubricated; when the device switches from the working state back to the initial state, the oiling part 11 retracts and crosses the supporting end of the gasket tube 4 and returns to the enclosed space of the gasket tube 4, and the top of the oiling part 11 retracted into the gasket tube 4 is not higher than the supporting end of the gasket tube 4; compared with the background technology in which the accumulated grease 2a accumulates at the bottom end opening position of the pipe 2 to be lubricated, the present device can form a uniform lubricating oil layer 2b on the inner wall of the pipe 2 to be lubricated while the oiling part 11 completely returns to the gasket tube 4, and scrapes the excess grease into the gasket tube 2, eliminating the process of manually cleaning the accumulated grease 2a.

[0042] Furthermore, although the device is provided with a pressure plate, which presses the top end of the pipe to be lubricated 2 so that the bottom end of the pipe to be lubricated 2 abuts against the top end of the gasket 4, in order to prevent the two abutting pipes from being offset and misaligned when the oiling portion 11 is lubricated, the device also includes a positioning seat 3 provided on the table 1, which can fix the position of the pipe to be lubricated 2 and the gasket 4; specifically, the positioning seat 3 is provided with a positioning hole 34 that matches the outer diameter and cross-sectional shape of the gasket 4, and the positioning hole 34 passes through the positioning seat 3; the gasket 4 is in the positioning hole 34, and the supporting end of the gasket 4 passes through the positioning hole 34 and abuts against the pipe to be lubricated. The bottom end of the lubricating pipe fitting 2 and the top end of the positioning seat 3 are provided with a plurality of protrusions 31 arranged around the positioning hole 34, the inner side surface of the protrusion 31 matches the outer wall surface of the gasket tube 4, and the height of the protrusion 31 is greater than the height of the supporting end of the gasket tube 4; the plurality of protrusions 31 that are higher than the supporting end of the gasket tube 4 can form a guiding effect, which is convenient for the installation and positioning of the bottom end of the pipe fitting 2 to be lubricated, so that when the bottom end of the pipe fitting 2 to be lubricated is against the supporting end of the gasket tube 4, the inner side surface of the protrusion 31 is close to the outer wall of the pipe fitting 2 to be lubricated and the outer wall of the gasket tube 4, so as to fix the position of the pipe fitting 2 to be lubricated and the gasket tube 4, thereby avoiding misalignment of the pipe fitting 2 to be lubricated and the gasket tube 4.

[0043] Furthermore, excess grease will be scraped into the gasket tube 4 by the oiling portion 11, but the internal space of the gasket tube 4 is limited. After lubricating multiple pipes, although excess grease will not accumulate at the bottom opening of the pipe 4 to be lubricated, it will accumulate in the gasket tube 4. Therefore, in order to avoid this situation, at least one oil drain port 41 is provided at a position of the gasket tube 4 close to the table 1, and an avoidance notch 33 corresponding to the position of the oil drain port 41 is provided on the positioning seat 3, and the avoidance notch 33 is connected to the positioning hole 34; so that the excess grease scraped into the gasket tube 4 can be discharged through the oil drain port 41 and the avoidance notch 33, thereby avoiding excessive accumulation of grease in the gasket tube 4.

[0044] Furthermore, excess grease discharged through the oil drain port 41 and the avoidance gap 33 will adhere to the table top 1. In order to clean the grease, the positioning seat 3 is detachably fixed to the table top 1. Specifically, a plurality of screw holes (not shown) are provided on the table top 1, and a through hole 32 corresponding to the position of the screw hole is provided on the positioning seat 3. The screw passes through the through hole 32 and is screwed into the screw hole to fix the positioning seat 3 on the table top 1. The screw connection method has a good connection effect, so that the positioning seat 3 can form a stable positioning effect for the lubricated pipe fitting 2 and the gasket 4, and the screw is also easy to remove, so that the positioning seat 3 can be quickly removed from the table top 1. This detachable design allows the positioning seat 3 to be removed from the table top 1 after the lubrication of the lubricated pipe fitting 2 is completed, so as to facilitate centralized cleaning of excess grease.

[0045] Furthermore, when the lubricated pipe 2 is installed or disassembled, it will inevitably collide with the positioning seat 3. In order to avoid damage to the lubricated pipe 2 due to collision, the positioning seat 3 is made of nylon or plastic; nylon or plastic has low hardness, which can prevent the lubricated pipe 2 from being damaged when it collides with the positioning seat 3 during assembly or disassembly.

[0046] Furthermore, the length of the gasket tube 4 refers to the distance from the supporting end of the gasket tube 4 to the lower end of the gasket tube 4, and the length of the gasket tube 4 is much smaller than the pipe fitting 2 to be lubricated; specifically, the length range of the gasket tube 4 is 20mm-80mm, and this length range is relatively reasonable, so that the gasket tube 4 can raise the pipe fitting 2 to be lubricated, and can ensure that the retracted oiling part 11 can be completely returned to the gasket tube 4, so that the lubricating oil layer on the inner wall of the pipe fitting 2 to be lubricated is more uniform.

[0047] Example 2: Figure 8 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, a protrusion 31 that is higher than the supporting end of the gasket tube 4 is not provided on the positioning seat 3, but a positioning hole 34 that matches the outer diameter and cross-sectional shape of the gasket tube 4 is provided on the positioning seat 3, and the shape of the positioning hole 34 matches the cross-sectional shape of the pipe 3 to be lubricated; the positioning hole 34 passes through the positioning seat 3; the pipe 2 to be lubricated and the gasket tube 4 are located in the positioning hole 34 and are tightly attached to the inner wall of the positioning hole 34; the positioning hole 34 forms an embracing effect on the pipe 2 to be lubricated and the gasket tube 4 that are against each other, so as to avoid misalignment of the pipe 2 to be lubricated and the gasket tube 4, and can achieve the same positioning effect as in the above embodiment.

[0048] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
