Abstract

This utility model relates to the technical field of compressor pre-lubrication auxiliary tools, specifically to an auxiliary oil injection device for compressor pre-lubrication, including a support mechanism, a drive mechanism, and a controller. The support mechanism has a rotating rod, and a cam is fitted onto the rotating rod. The drive mechanism is kinetically connected to the rotating rod and drives the rotating rod to rotate. The controller is connected to the drive mechanism for control. This auxiliary oil injection device for compressor pre-lubrication uses the drive mechanism to power the rotating rod, causing the cam on the rotating rod to rotate synchronously.

Description

Technical Field

[0001] This utility model relates to the technical field of compressor pre-lubrication auxiliary tools, specifically to an auxiliary oil injection device for compressor pre-lubrication. Background Technology

[0002] Manual pre-lubrication of large compressors before startup is an important step to ensure safe operation and reduce wear. Existing CNG reciprocating compressors may start and stop intermittently according to natural gas dispatch instructions. Before startup, it is necessary to use an oiler to pre-lubricate key components such as cylinders, pistons, and bearings to effectively reduce friction loss and ensure reliable operation of the equipment. A single reciprocating compressor is generally equipped with one or more manual oiler pumps. The oiler pump is connected to the corresponding lubrication point through pipelines and is connected to the oil tank assembly. The oiler pump is equipped with a manual oiling handle and a stroke adjustment knob. After pressing the stroke adjustment before starting the compressor, the manual oiling handle needs to be pressed a certain number of times, such as 100 times, until the indicator on the oil flow display flashes to achieve pre-lubrication.

[0003] However, due to the large number of presses required for a single start-up, the existing manual operation of the oil injection handle greatly increases the workload of the staff, and the small operating space makes the pre-lubrication operation time-consuming and laborious, which is not conducive to the smooth pre-lubrication of the compressor. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the need for manual operation of the oil injection handle for pre-lubrication before starting the compressor, which is time-consuming and laborious and not conducive to the smooth pre-lubrication of the compressor. This invention provides an auxiliary oil injection device for compressor pre-lubrication.

[0005] This utility model provides an auxiliary oil injection device for compressor pre-lubrication, comprising:

[0006] A support mechanism, wherein a rotating rod is provided on the support mechanism, and a cam is fitted on the rotating rod;

[0007] A drive mechanism is connected to the rotating rod in a transmission manner, and the drive mechanism is used to drive the rotating rod to rotate;

[0008] A controller, which is connected to the drive mechanism.

[0009] This utility model discloses an auxiliary oil injection device for compressor pre-lubrication. The drive mechanism provides power to drive the rotating rod to rotate, and the cam on the rotating rod rotates synchronously. The cam performs a reciprocating pressing operation on the oil injection handle at the appropriate position, realizing the mechanized pressing of the compressor oil injection handle. This eliminates the need for manual operation to press the oil injection handle during the compressor pre-lubrication process, reducing workload and making the pressing more uniform, which helps to reduce pre-lubrication time.

[0010] Preferably, the rotating rod is provided with at least two cams, with adjacent cams arranged opposite each other on their major axis sides. This allows the auxiliary lubrication device to accommodate repeated pressing and pre-lubrication operations of at least two lubrication handles.

[0011] Preferably, the rotating rod has a threaded section, and the cam is threadedly connected to the threaded section. The threaded section has a limiting element for restricting the movement of the cam. This ensures that the cam is stably positioned on the rotating rod and allows for adaptive position adjustment of the cam according to the position of the oil filling handle.

[0012] Preferably, the support mechanism includes two opposing bracket portions, with the rotating rod passing through the bracket portion and rotatably engaging with it. The two independent bracket portions allow for convenient adjustment of the support mechanism's position according to installation conditions.

[0013] Preferably, the support unit includes a base plate and an upright plate. The rotating rod passes through the upright plate. The base plate is provided with a height adjustment part. The upright plate and the height adjustment part are detachably connected by a height adjustment structure. The height adjustment structure includes a slotted hole and a limiting bolt, and the limiting bolt can pass through the slotted hole. This allows the support unit to adaptively adjust its height according to the height of the oil filling handle.

[0014] Preferably, the base plate is provided with fixing holes. The fixing holes enable stable installation of the bracket.

[0015] Preferably, the base plate is equipped with a magnetic suction structure. This magnetic suction structure enables stable installation when it is inconvenient to fix the bracket.

[0016] Preferably, the system further includes a limiting frame, which includes a limiting rod. The bottom end of the limiting rod is hinged to the base plate, and the top end is provided with a retaining part. The rotating rod has a prism segment adapted to the retaining part. The limiting frame temporarily restricts the rotation of the rotating rod when oiling is not required, keeping the cam disengaged from the oiling handle and preventing the cam from affecting the up-and-down movement of the oiling handle driven by the internal power of the compressor.

[0017] Preferably, the controller signal is connected to the metering mechanism, which is linked to the drive mechanism. The metering mechanism includes a counter and / or a flow meter. The metering mechanism enables accurate measurement of the amount of oil injected during pre-lubrication.

[0018] Preferably, the controller is connected to an alarm mechanism. The alarm mechanism can remind workers that pre-lubrication is complete.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model provides an auxiliary oil injection device for compressor pre-lubrication. The drive mechanism provides power to drive the rotating rod to rotate, so that the cam on the rotating rod rotates synchronously. The cam performs a reciprocating pressing operation on the oil injection handle at the appropriate position, realizing the mechanized pressing of the compressor oil injection handle. This eliminates the need for manual operation to press the oil injection handle during the compressor pre-lubrication process, reducing workload and making the pressing more uniform, which helps to reduce pre-lubrication time.

[0037] Example 1

[0038] like Figures 1-5 As shown, an auxiliary oil injection device for compressor pre-lubrication includes a support mechanism, a drive mechanism 4, and a controller 5. The support mechanism is provided with a rotating rod 2, and a cam 3 is mounted on the rotating rod 2. The drive mechanism 4 is connected to the rotating rod 2 for transmission and is used to drive the rotating rod 2 to rotate. The controller 5 is connected to the drive mechanism 4 for control.

[0039] The support mechanism is the main structure of the auxiliary oil injection device. It is used to support the rotating rod 2 and keep the cam 3 on the rotating rod 2 and the oil injection handle in a stable relative position.

[0040] In an optional embodiment, at least two cams 3 may be provided on the rotating rod 2, and two adjacent cams 3 may be arranged opposite to each other on the long axis side.

[0041] Multiple cams 3 are arranged at intervals along the axis of the rotating rod 2 to accommodate the pre-lubrication operation of compressors with multiple oil injection handles. At the same time, by restricting the installation orientation of adjacent cams 3, two cams 3 on the same compressor can be pressed alternately in a cycle, so that the two oil injection handles are pressed repeatedly in a cycle, which is consistent with the pre-lubrication operation requirements of existing compressors with multiple oil injection handles.

[0042] In an optional embodiment, a threaded section 21 may be provided on the rotating rod 2, and the cam 3 may be threadedly connected to the threaded section 21. The threaded section 21 may be provided with a limiting member 6 for restricting the movement of the cam 3.

[0043] Cam 3 is threadedly connected to rotating rod 2 and limited by limiting member 6, so that cam 3 is stably set on rotating rod 2 and the position of cam 3 can be adaptively adjusted according to the position of oiling handle.

[0044] In an optional embodiment, the limiting member 6 may be a nut.

[0045] In an optional embodiment, the limiting member 6 may be a pin that passes through the cam 3 and the rotating rod 2.

[0046] In an optional embodiment, the support mechanism may include two opposing bracket parts 1, through which a rotating rod 2 passes and rotatably engages with the bracket parts 1. The two independent bracket parts 1 allow for convenient adjustment of the support mechanism's position according to installation conditions. By moving the two bracket parts 1 relative to each other, the distance between them can be changed, allowing the bracket parts 1 to be positioned in different locations to facilitate stable fixation of the support mechanism.

[0047] In an optional embodiment, a bearing may be provided on the support part 1, and the rotating rod 2 may pass through the bearing to achieve smooth rotation of the rotating rod 2.

[0048] In an optional embodiment, the support unit 1 includes a base plate 11 and an upright plate 14. The rotating rod 2 passes through the upright plate 14. The base plate 11 is provided with a height adjustment part 13. The upright plate 14 and the height adjustment part 13 are detachably connected by a height adjustment structure. The height adjustment structure may include a slotted hole 15 and a limiting bolt 16, which can pass through the slotted hole 15. This allows the support unit 1 to adaptively adjust its height according to the stroke of the oil filling handle.

[0049] In optional implementations, such as Figure 2 The right-side support 1 shown in the diagram has a height adjustment part 13, which can be a sleeve structure mounted on the base plate 11. The sleeve structure can be a rectangular tube section mounted on the base plate 11. The upright plate 14 can be a plate-shaped, tubular, or rod-shaped structure that can be inserted into the rectangular tube section. The sleeve structure can be fixedly and vertically connected to the base plate 11. Slot holes 15 can be provided on both the sleeve structure and the upright plate 14. By using a limiting bolt 16 passing through the slot hole 15 and a conventional nut, the relative position of the upright plate 14 and the sleeve structure can be limited. By adjusting the relative position of the upright plate 14 and the sleeve structure, the overall height of the upright plate 14 and the sleeve structure after being stacked can be changed, thereby adjusting the height of the rotating rod 2 and adjusting the relative position of the cam 3 and the oil injection handle. This further ensures that the oil injection stroke of the cam 3 and the oil injection handle are matched.

[0050] In optional implementations, such as Figure 2 The left support part 1 shown in the figure, the height adjustment part 13 can also be a plate-shaped structural component with strip holes 15 or multiple round holes. The upright plate 14 can be partially attached to the plate-shaped structural component, and the overall height of the upright plate 14 can be adjusted by the limiting bolts 16 passing through different positions.

[0051] In an optional embodiment, the base plate 11 may be provided with fixing holes 12. The fixing holes 12 enable stable installation of the bracket part 1.

[0052] In an optional embodiment, the fixing hole 12 can be a through hole, equipped with a bolt. The number, shape and size of the fixing holes 12 can be structurally adjusted according to the actual state of the position on the compressor that can be used to install the fixing support mechanism. Preferably, it can be adapted to the position and hole diameter of the locking bolt on the compressor that is used to install the oiler pump.

[0053] In an optional embodiment, the base plate 11 is provided with a magnetic attraction structure. This magnetic attraction structure enables stable installation when the support portion 1 is inconvenient to fix. The magnetic attraction structure can be a fixed connection or an embedded component within the base plate 11. Through its magnetic characteristics, it can magnetically connect to the compressor, thus achieving stable installation of the support mechanism.

[0054] In one or more implementations, such as Figure 1As shown, the auxiliary oiling mechanism may also include a limiting frame 7, which is used to limit the rotation of the rotating rod 2. The limiting frame 7 may include a limiting rod 71, the bottom end of which is hinged to the base plate 11, and the top end of which is provided with a retaining part 72. The rotating rod 2 is provided with a prism section 22 that is adapted to the retaining part 72. By using the limiting frame 7, the rotation of the rotating rod 2 can be temporarily restricted when oiling is not required, so that the cam 3 is kept disengaged from the oiling handle, and the cam 3 is prevented from affecting the up-and-down movement of the oiling handle under the power of the compressor during the normal oiling process.

[0055] In an optional embodiment, the prism segment 22 on the rotating rod 2 can be a quadrangular prism segment 22, and the holding part 72 can hold the quadrangular prism segment 22 to restrict the rotation of the rotating rod 2.

[0056] In an optional implementation, the limiting rod 71 can adopt a multi-segment structure with hinged connection according to the actual situation, so as to realize the length adjustment of the limiting rod 71 and adapt to the pressing stroke matching under different oil injection strokes.

[0057] In one or more embodiments, the controller 5 may also be signal-connected to a metering mechanism, which is linked to the drive mechanism 4. The metering mechanism may include a counter and / or a flow meter. The metering mechanism enables accurate measurement of the amount of oil injected during pre-lubrication.

[0058] In an optional implementation, a counter is used to record the number of rotations of the drive mechanism 4. The number of rotations of the drive mechanism 4 is the same as the number of rotations of the rotating rod 2, which is consistent with the number of rotations of the cam 3. By obtaining the number of rotations of the cam 3 through the counter, the number of pre-lubrication presses of the oiling handle can be obtained, thus ensuring the smooth progress of pre-lubrication.

[0059] In an optional implementation, the flow meter is used to monitor the amount of lubricating oil injected during the pre-lubrication process, thereby achieving quantitative oil injection for the pre-lubrication operation and facilitating the automated control of the auxiliary oil injection device.

[0060] In an optional implementation, the drive mechanism 4 may be a motor, the metering mechanism may be an electronic component with a corresponding function, and the controller 5 may be an electronic component that works in conjunction with the corresponding function and component.

[0061] In an optional implementation, the controller 5 is connected to an alarm mechanism. The alarm mechanism can alert staff that pre-lubrication is complete.

[0062] In an optional implementation, the alarm mechanism can be an audible and visual alarm, such as a buzzer, which can be used in combination with a conventional PLC or microcontroller 5.

[0063] This embodiment provides an auxiliary oil injection device for compressor pre-lubrication. When in use, as follows: Figures 3-4As shown, the auxiliary oiling device can be installed above the oiler pump of the compressor. Its support mechanism is adapted to the locking bolts on the compressor for installing the oiler pump. The cam 3 is in contact with the top surface of the oiling handle. The motor is used as the drive mechanism 4 to drive the rotating rod 2 to rotate, which in turn drives the cam 3 to rotate. Combined with the large and small head structure of the long axis of the cam 3, the oiling handle can be repeatedly pressed to realize the mechanical operation of pre-lubrication of the compressor, thereby improving the pre-lubrication effect and efficiency.

[0064] This embodiment provides an auxiliary oil injection device for compressor pre-lubrication. The drive mechanism 4 provides power to drive the rotating rod 2 to rotate, causing the cam 3 on the rotating rod 2 to rotate synchronously. The cam 3 then performs a reciprocating pressing operation on the oil injection handle at the appropriate position, realizing the mechanized pressing of the compressor oil injection handle. This eliminates the need for manual operation to press the oil injection handle during the compressor pre-lubrication process, reducing workload and ensuring more uniform pressing, which helps to reduce pre-lubrication time.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
