Description

Technical Field

[0001] This utility model belongs to the technical field of compressor oiler oil pump device, specifically relating to an auxiliary oil injection device for a compressor oiler. Background Technology

[0002] Currently, natural gas compression operations generally employ reciprocating compressors. The oil injector in the compressor's high-pressure lubrication system provides lubricating oil to the cylinders and packing. During operation, the lubricating oil is pumped by the oil pump on the oil injector to the distributor, which then distributes the lubricating oil evenly to the cylinders and packing. Before each compressor start-up, lubricating oil is typically manually pumped into each lubrication line until all air is expelled and the lubricating oil reaches all lubrication points. This ensures sufficient lubrication of the compressor cylinders and packing, maintains unobstructed oil flow, and guarantees adequate lubrication of moving parts such as the piston and piston rod during compressor startup, reducing piston ring wear.

[0003] Current technology typically involves pumping oil by hand or using tools such as flathead screwdrivers and open-end wrenches. Due to the significant spring force of the oil injector, manual pumping is physically demanding and can easily lead to operator fatigue. Furthermore, the operating space is often quite confined, posing practical difficulties and safety hazards. When using incompatible tools like flathead screwdrivers or open-end wrenches, the oil cup in the pipeline is often used as a support point, which can easily cause tool slippage and result in hand injuries, posing a significant personal safety hazard.

[0004] To address the aforementioned issues, Chinese invention patent application CN116066327A discloses an oil pumping device for a compressor oil injector, comprising a fixing part and a clamping part (i.e., an operating lever). The fixing part is L-shaped, with one end of the L-shape being a snap-fit ​​end and the other end being a first connecting end. The snap-fit ​​end adopts a double-tooth structure for engaging with the oil inlet nut of the oil injector. One end of the clamping part is an operating end, and the other end is a second connecting end. The first connecting end is connected to the second connecting end. The clamping part abuts against the oil injector's oil injection rod.

[0005] However, in actual use, after prolonged use, the compressor surface will accumulate some oil stains. During oil pumping, slippage is likely to occur at the mating point between the snap-fit ​​end and the oil inlet nut, or at the contact point between the snap-fit ​​end and the compressor surface, making the fit between the snap-fit ​​end and the oil inlet nut unstable. In addition, the snap-fit ​​end with the double tooth structure needs to be precisely aligned with the oil inlet nut. If there is insufficient space between the oil inlet nut and the pump body of the oil injector, or if the space at the position of the oil inlet nut is narrow, the snap-fit ​​end will have difficulty achieving a snap-fit ​​fit with the nut. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary oil injection device for a compressor oiler to solve the problem that the snap-fit ​​end and the oil inlet pipe nut are prone to slippage when there is oil on the surface of the compressor.

[0007] To achieve the above objectives, the auxiliary oil injection device for the compressor oiler in this utility model adopts the following technical solution:

[0008] An auxiliary oil injection device for a compressor oiler includes an operating lever, an annular clamp and its fastening structure, the clamp having a clamping part for engaging with an oil injection line and ear plates extending from both ends of the clamping part, one of the ear plates being provided with a support structure for supporting the operating lever.

[0009] Furthermore, the support structure is a groove.

[0010] Furthermore, the opening direction of the groove is perpendicular or parallel to the force direction of the operating lever.

[0011] Furthermore, the support structure is a rotating shaft or a shaft hole, and the operating rod has a hinged end adapted to the rotating shaft or shaft hole, the hinged end being rotatably connected to the support structure.

[0012] Furthermore, the operating lever has an anti-detachment structure, which cooperates with the support structure to prevent the operating lever from detaching along its axial direction when force is applied.

[0013] Furthermore, the anti-detachment structure is one of a spherical structure, an arc-shaped structure, or a pin structure.

[0014] Furthermore, the length of the ear plate with the support structure is greater than the length of the other ear plate without the support structure.

[0015] Furthermore, the bottom wall of the groove is an arc structure.

[0016] Furthermore, the groove is a U-shaped groove.

[0017] Furthermore, the fastening structure is a bolt and nut, and each of the ear plates has a corresponding mounting hole. The bolt passes through the mounting hole and cooperates with the nut to make the clamp hold the oil injection line tightly.

[0018] The beneficial effects of this utility model are as follows: The auxiliary oil injection device for compressor oilers provided by this utility model is an improvement on existing technology. Through a fastening structure, the clamping part of the annular clamp is tightly engaged with the oil injection pipeline, firmly fixing the clamp to the oil injection pipeline. The operating lever, through the support structure on the ear plate extending from the clamping part, stably cooperates with the clamp, thus providing a stable support point for the operating lever during the oil injection process. This effectively avoids the influence of oil contamination on the stability of the support point, allowing operators to more accurately control the oil injection action and improving the reliability and stability of the oil injection operation.

[0022] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0023] To address the problems in the background technology, the core inventive concept of this utility model is as follows: The auxiliary oil injection device for compressor oiler provided by this utility model uses a fastening structure to engage the clamping part of the clamp with the oil injection pipeline. The operating lever cooperates with the support structure on the ear plate extending from the clamping part, thereby providing a stable and firm support point for the operating lever during the oil injection process, avoiding the influence of oil stains on the compressor surface on the stability of the support point.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] An embodiment of the compressor oiler auxiliary oil injection device of this utility model:

[0026] like Figure 1 and Figure 2 As shown, the compressor oiler auxiliary oil injection device provided in this embodiment includes an operating lever 2 and an annular clamp 1 for supporting the operating lever 2 during oil injection, as well as a fastening structure for clamping the clamp 1 onto the oil injection line 3. The clamp 1 has a clamping part 11 for engaging with the oil injection line 3 and ear plates extending from both ends of the clamping part 11, one of which is provided with a support structure for supporting the operating lever 2.

[0027] In the above embodiment, the compressor oiler auxiliary oiling device mainly consists of two parts: an operating lever 2 and a clamp 1. Compared with the prior art, it has a simple structure and is easy to manufacture and maintain. The clamping part 11 of the clamp 1 grips the oiling pipeline 3 through a fastening structure, thus firmly fixing the clamp 1 to the oiling pipeline 3. The operating lever 2 achieves stable cooperation with the clamp 1 through the support structure on the ear plate extending from the clamping part 11, thereby providing a stable support point for the operating lever 2 during the oiling process. This effectively avoids the influence of oil contamination on the stability of the support point, allowing the operator to control the oiling action more precisely and improving the reliability and stability of the oiling operation. Simultaneously, the clamping part 11 allows for convenient and quick fixing or removal of the clamp 1 from the oiling pipeline 3 without the need for complex installation tools and procedures.

[0028] In this embodiment, the clamping part 11 has an opening for inserting the oil injection line 3. The shape of the clamping part 11 is similar to the shape of the oil injection line 3 it is adapted to, and it has a shape that fits the oil injection line 3 to increase the contact area between the clamping part 11 and the oil injection line 3 and improve the stability of clamping and fixing. It should be understood that the clamping part 11 can be designed according to different specifications of oil injection lines 3, so as to be applicable to compressor oilers of different specifications and models.

[0029] The clamping part 11 has ear plates extending from both ends of its opening away from the clamping part 11. Each ear plate includes a first ear plate 12 and a second ear plate 13 disposed opposite to each other. The second ear plate 13 has a support structure for supporting the operating rod 2. Specifically, a groove 131 is provided at the end of the second ear plate 13 away from the clamping part 11. The groove wall of the groove 131 forms a support point for the operating rod 2, and the groove 131 constitutes the support structure for supporting the operating rod 2. In other embodiments, the support structure may only be provided on the first ear plate 12; a capping structure may also be provided at the opening of the groove 131 to simultaneously restrict the horizontal displacement of the operating rod 2.

[0030] In the above embodiments, during the oil injection and pressing operation, the positioning and relative fixation of the operating rod 2 can be completed simply by placing the operating rod 2 into the groove 131, without the need for additional fixing steps or tools, which reduces the difficulty of operation and improves work efficiency; the design of the groove 131 makes the connection between the operating rod 2 and the clamp 1 more compact, reduces the overall space occupied by the device, and can better adapt to the production site conditions.

[0031] In this embodiment, the opening direction of the groove 131 is perpendicular to the force direction of the operating lever 2, that is, the opening direction of the groove 131 is towards the centerline extension direction of the oil injection line 3. This can better limit the vertical displacement of the operating lever 2 and ensure the stability of the operating lever 2 during operation; at the same time, it also avoids interference between the operating lever 2 and the oil injection line 3 when pressed.

[0032] In other embodiments, the opening direction of the groove 131 is parallel to the force application direction of the operating rod 2, that is, the opening of the groove 131 faces a direction perpendicular to the horizontal plane. In this case, a matching cover structure can be provided at the opening of the groove 131 to limit the displacement of the operating rod 2 in the vertical and horizontal directions. Alternatively, the connection between the operating rod and the groove wall can be realized by a pin structure. Specifically, one possible implementation is to use a pin as a connector, which passes through a pre-machined hole on the operating rod and the groove. The rotation of the operating rod is realized by the cooperation between the pin and the hole, while the axial disengagement of the operating rod can be restricted when force is applied.

[0033] In this embodiment, the bottom wall of the groove 131 is an arc-shaped structure. Preferably, the groove 131 is a U-shaped groove with its opening direction perpendicular to the force direction of the operating rod 2. The arc-shaped groove 131 can better fit with the operating rod 2, forming good contact, making the operation of the operating rod 2 within the groove 131 more stable, and reducing the risk of the operating rod 2 getting stuck in the groove 131 during pressing operations; at the same time, the increased contact area between the bottom wall of the arc groove and the operating rod 2 helps to reduce wear between the operating rod 2 and the groove 131. The U-shaped groove structure can effectively limit the displacement of the operating rod 2 in the vertical direction and part of the horizontal direction, ensuring that the operating rod 2 is always in a stable working state. In other embodiments, the groove can be a semi-circular groove, or the bottom wall of the groove can be a rectangular or other non-arc-shaped structure. In this case, a cover structure that matches the groove can be configured as needed to limit the displacement of the operating rod in the vertical and horizontal directions.

[0034] It should be understood that the opening distance of the groove 131 is preferably such that it is convenient to insert the operating lever 2.

[0035] In this embodiment, the length of the ear plate with a support structure is greater than the length of the other ear plate without a support structure. Specifically, the length of the second ear plate 13 with a groove 131 is greater than the length of the first ear plate 12. The longer ear plate length provides ample space for the arrangement of the groove 131 and also provides a larger operating space for the operating lever 2, reducing the possibility of interference between the operating lever 2 and other components and improving the flexibility of operation.

[0036] In other embodiments, the two ear plates can be of equal length. In this case, when inserting the operating rod 2, the end of the operating rod 2 that contacts the groove 131 should not extend beyond the ear plate without the groove 131, that is, that end should be between the two ear plates.

[0037] In this embodiment, the fastening structure is a bolt and nut assembly. Mounting holes (not shown in the figure) for bolts 4 are provided at corresponding positions on the first ear plate 12 and the second ear plate 13. The bolt 4 passes through the mounting hole and engages with the nut 41 to tighten the clamp 1 onto the oil injection line 3. It should be noted that the size and position of the mounting hole must match the specifications of the bolt and nut assembly to ensure that the bolt 4 can pass smoothly through the mounting hole and engage tightly with the nut 41. The bolt and nut assembly, as a fastening structure, is simple in structure, easy to operate, and provides reliable fastening. It allows for convenient adjustment of the clamping force of the clamp 1 on the oil injection line 3. The corresponding mounting holes provide accurate positioning for the installation of the bolt 4 and nut 41.

[0038] In this embodiment, the central axis of the mounting hole for the bolt 4 is located between the oil injection line 3 and the supporting structure. When the clamp 1 is tightened, the tightening structure is closer to the oil injection line 3, which can reasonably distribute the tightening force to the clamping part 11 and the ear plate that clamp the oil injection line 3, so that the clamp 1 can fit tightly with the oil injection line 3. During the oil injection operation, the pressing pressure applied to the operating lever 2 can be reasonably transmitted to the oil injection line 3 through the ear plate. At the same time, the reaction force of the oil injection line 3 on the clamp 1 can also be effectively dispersed, avoiding excessive local stress and ensuring the stability of the clamp 1 structure. At the same time, it helps to achieve the compactness of the compressor oiler auxiliary oil injection device structure, which is convenient for arrangement and use in a relatively limited operating space.

[0039] In other embodiments, the central axis of the mounting hole is away from the clamping part 11, specifically, it is located on the side of the groove 131 away from the clamping part 11. In this case, the lengths of the two ear plates should be set to be equal.

[0040] It should be understood that a reasonable distance should be maintained between the groove 131 and the mounting hole so that the end of the operating rod 2 that contacts the groove 131 does not interfere with the bolt 4 during the oil filling operation and the overall structure is compact. The specific distance can be set as needed, and this embodiment does not impose any restrictions on it.

[0041] The operating lever 2 includes a gripping part 21 for the operator to hold during oil pumping operation and a clamping part 22 for cooperating with the oil injector's injection rod. Specifically, the gripping part 21 and the clamping part 22 are connected sequentially; the gripping part 21 has a circular cross-section, including a constant diameter section and a variable diameter section whose cross-sectional size gradually decreases from the gripping part 21 to the clamping part 22, wherein the two ends of the variable diameter section are connected to the constant diameter section and the clamping part 22, respectively; the clamping part 22 also has a circular cross-section, and its cross-sectional size gradually decreases from the gripping part 21 towards the end away from the gripping part 21. It should be understood that the gripping part 21 and the clamping part 22 can be integrally manufactured by casting or other methods; the gripping part 21 and the clamping part 22 can also be manufactured separately and connected as a whole by threaded engagement or welding.

[0042] In other embodiments, a separate grip portion is not provided; the cross-section of the operating lever is circular, and the cross-sectional size gradually decreases from the grip portion towards the end away from the grip portion; or, the operating lever is a cylindrical structure of uniform diameter. It should be understood that the shape, size, etc., of the operating lever 2 can be reasonably set according to actual needs to ensure the convenience and reliability of operation, and this embodiment does not limit this.

[0043] As a further embodiment, the operating lever 2 is provided with an anti-detachment structure, which cooperates with the support structure to prevent the operating lever 2 from detaching axially when force is applied. Specifically, the operating lever 2 is provided with an anti-detachment part 23 for anti-detachment cooperation with the groove 131 of the clamp 1. The anti-detachment part 23 is located at the end of the operating lever 2 away from the gripping part 21. Thus, the gripping part 21, the pressing part 22, and the anti-detachment part 23 are sequentially connected to form the operating lever 2. During the oil filling operation, the anti-detachment part 23 of the operating lever 2 cooperates with the groove sidewall of the groove 131 of the ear plate to effectively prevent the operating lever 2 from detaching axially, improving the safety of the oil filling operation and ensuring the personal safety of the operator.

[0044] In this embodiment, the anti-detachment part 23 is a spherical structure, specifically, an anti-detachment ball. Of course, in other embodiments, the anti-detachment part can be an arc-shaped structure, specifically, an arc-shaped plate, with the opening of the arc-shaped plate facing away from the gripping part 21. The anti-detachment ball or arc-shaped plate constitutes the anti-detachment structure of the operating lever 2. The spherical or arc-shaped structure allows the clamping part 22 to have multi-directional mobility within the groove 131 of the clamp 1, avoiding the risk of jamming due to angular deviation; simultaneously, the surface of the spherical or arc-shaped structure can automatically adjust the contact angle with the groove 131 to adapt to different installation environments.

[0045] In another embodiment, the end of the operating lever furthest from the grip can be hinged to the ear plate, allowing the operating lever to rotate around the hinge point to complete the pressing operation; in this case, the hinge structure forms an anti-disengagement structure for the operating lever. Accordingly, the end structure of the operating lever and the ear plate structure need to be adjusted accordingly. Specifically, the ear plate is provided with a pivot or shaft hole, and the operating lever has a hinge end adapted to the pivot or shaft hole, the hinge end being rotatably connected to the pivot or shaft hole; the pivot or shaft hole constitutes the support structure of the ear plate. The operating lever and the support structure are connected by a hinge, resulting in a relatively simple and reliable connection; at the same time, it ensures free rotation within a certain range during operation.

[0046] In this embodiment, to prevent slippage during operation, the outer surface of the grip 21 is provided with an anti-slip structure. Specifically, the anti-slip structure can be any one of heat shrink tubing, silicone sleeve, or knurled structure, or other effective anti-slip structures, so as to effectively increase the friction and grip stability of the grip 21 during operation.

[0047] The auxiliary oiling device for the compressor oiler provided by this utility model is used by clamping part 11 of clamp 1 to attach clamp 1 to the oiling line 3 of the oiler. The specific installation direction is preferably for easy pressing operation. Clamp 1 is tightened with bolts 4 and nuts 41. The end of the pressing part 22 of the operating rod 2 near the anti-disengagement part 23 is inserted into the groove 131 of the ear plate, and the pressing part 22 is aligned with the oiling rod of the oiler for pressing operation. If the pressing direction is deviated during operation, bolts 4 and nuts 41 should be loosened to adjust the direction of groove 131, or the position of the operating rod 2 should be moved appropriately so that the pressing part 22 of the operating rod 2 corresponds to the position of the oiler.

[0048] Of course, with the clamp 1 providing stable support, and on the premise of ensuring operational safety, auxiliary tools such as a flathead screwdriver can be used to replace the operating lever 2 for pressing operations.

[0049] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some technical features, or organically combine different specific implementation methods to create the specific implementation methods shown in the accompanying drawings. Of course, those skilled in the art can also create other specific implementation methods not shown in the accompanying drawings. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
