Description

Technical Field

[0001] This utility model relates to the field of grease injection equipment technology, and more specifically to a single-point automatic lubricator. Background Technology

[0002] Currently, most grease injection for factory equipment maintenance is done manually, either by hand or using a grease gun. Manual grease application is costly, and the timing and amount of grease added cannot be accurately controlled. Adding too much grease can cause overheating and damage to the equipment, wasting grease without providing adequate lubrication. Human error can also lead to forgetting to add grease, resulting in severe bearing wear; statistics show that 90% of bearing failures are caused by improper lubrication.

[0003] In addition, in some working conditions (such as in chemical plants), the equipment is too scattered; in some working conditions (such as in cement plants and power plants), the equipment is too large; and in some working conditions (such as in coal mines), it is very difficult to manually add grease to many parts of the equipment, so the workload is large and the management is difficult.

[0004] Based on the above, there is an urgent need to remotely control the lubricator to achieve controlled grease injection on specific equipment and monitor the status of the lubricator for better management. Utility Model Content

[0005] To address the technical problems existing in existing automatic lubricators, the first aspect of this utility model proposes a single-point automatic lubricator, comprising:

[0006] The housing includes a first housing and a second housing, wherein the second housing is detachably connected to the first housing;

[0007] A piston component is disposed inside the first housing, and the interior of the first housing is divided into a first space and a second space. The first space is used to contain grease, and the first housing is provided with a grease injection port communicating with the first space.

[0008] A driving component is disposed in a third space within the second housing. The driving component is used to drive the piston component to move closer to or away from the grease injection port, causing the piston component to squeeze the first space, and the grease in the first space to flow out controllably from the grease injection port.

[0009] The control circuit board is located in the third space inside the second housing, and its surface is integrated with a communication module, a sensor interface and a motor drive circuit.

[0012] The angular displacement detector is used to detect the number of rotations of the drive component.

[0013] Preferably, the piston component is connected to a piston rod that passes through the second space and extends into the third space, and the driving component is used to drive the piston rod.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] This utility model's single-point automatic lubricator uses a drive component and screw thread transmission to drive an internal piston to move axially, causing grease to be extruded in a measured amount. Through a built-in remote communication module, remote grease injection can be achieved, and an angular displacement detector can monitor the angular displacement of the drive component.

[0029] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0030] Combination Figure 1 and Figure 2 As shown, the first aspect of this utility model proposes a single-point automatic lubricator, including a housing, a piston component 20, a drive component 30, a control circuit board 40, a power supply module 50, and a sensor component.

[0031] like Figure 1 and Figure 2 As shown, the housing includes a first housing 11 and a second housing 12, with the second housing 12 being detachably connected to the first housing 11.

[0032] Combination Figure 3 and Figure 4 As shown, the piston component 20 is disposed inside the first housing 11, and the interior of the first housing 11 is divided into a first space 101 and a second space 102. The first space 101 is used to contain grease, and the first housing 11 is provided with a grease injection port 14 that communicates with the first space 101.

[0033] It should be understood that the piston component 20 is designed to divide the space in the first housing 11 into two independent parts to prevent grease from entering the second space 102 from the first space 101. Furthermore, by moving the piston component 20, the size of the first space 101 can be changed, that is, the first space 101 is squeezed toward the grease injection port 14, so that the grease flows out from the grease injection port 14.

[0034] Furthermore, the drive component 30 is disposed in the third space 103 within the second housing 12. The drive component 30 is used to drive the piston component 20 to approach or move away from the grease injection port 14, so that the piston component 20 squeezes the first space 101, and the grease in the first space 101 flows out controllably from the grease injection port 14.

[0035] Specifically, during lubrication, the grease inlet 14 is connected to the grease inlet of the device. At this time, the first space 101 is in its largest state and is filled with grease. The drive component 30 drives the piston component 20 to move along its axial direction, changing the size of the first space 101 and squeezing out the grease.

[0036] To enable remote control, the control circuit board 40 is located in the third space 103 within the second housing 12, and its surface integrates a communication module, a sensor interface, and a motor drive circuit. Furthermore, the power supply module 50 is located in the third space 103 within the second housing 12 and is electrically connected to the drive component 30 and the control circuit board 40.

[0037] Thus, the driving status of the motor can be remotely controlled through the communication module, and the driving status of the motor can also be recorded and monitored. That is, according to the characteristics of the equipment to be lubricated, the driving component 30 can be remotely controlled in a timely manner, so that the grease in the first space 101 can be controlled to flow out through the grease injection port 14.

[0038] In a specific embodiment, if a predetermined amount of grease is extruded each time, the drive component 30 is controlled to run for a predetermined duration and rotate a predetermined number of times each time. For example, the drive component 30 can be remotely controlled to run continuously for 1 second or rotate 20 times using a mobile phone or computer. At this time, the grease is extruded in a fixed quantity.

[0039] Meanwhile, the backend can record this data to obtain information such as the remaining amount and usage of grease. If the remaining amount of grease is lower than the minimum threshold, this information can be visualized through the backend.

[0040] Furthermore, the sensor component is mounted inside or on the surface of the housing, and the sensor component includes an angular displacement detector electrically connected to the sensor interface; wherein the angular displacement detector is used to detect the number of rotations of the drive component 30.

[0041] Thus, the angular displacement detector can actually detect the operating status of the drive component 30 within a unit of time. For example, if the drive component 30 is remotely controlled to rotate 20 times in 1 second, but in reality it only rotates 10 times in 1 second and does not rotate 20 times, it indicates that the extrusion resistance of the grease injection port 14 is high and blockage may occur. Therefore, when the angular displacement detector detects that the operating status of the drive component 30 does not match the target drive status, the background can issue an alarm for the user to check.

[0042] If the target number of rotations of the drive motor is N, but the actual detected value of the angular displacement detector is less than N, it is determined that the grease injection port 14 is blocked.

[0043] Combination Figure 3 and Figure 4 As shown, a piston rod 21 is connected to the piston component 20, which passes through the second space 102 and extends to the third space 103. The drive component 30 is used to drive the piston rod 21.

[0044] In this way, the space where the grease is located on the piston rod 21 is isolated, preventing the transmission structure from contaminating the grease.

[0045] Furthermore, the first housing 11 is provided with a bracket 15 on the side facing the second housing 12, and a gear set 31 is provided on the bracket 15. The driving component 30 includes a drive motor, the output end of the drive motor is connected to the gear set 31, and the output end of the gear set 31 is connected to the piston rod 21.

[0046] Specifically, the transmission process is as follows: the drive motor rotates, which drives the small gear at its output end to rotate. The small gear drives the gear set 31 to rotate. A large gear 22 is fixed on the outer wall of the piston rod 21. The gear set 31 drives the large gear 22 to rotate. At the same time as the large gear 22 rotates, the piston rod 21 rotates. The piston rod 21 and the bracket 15 are connected by a threaded transmission, which causes the piston component 20 to move axially.

[0047] In an optional embodiment, the angular displacement detector includes an infrared sensor, and the bracket 15 is provided with an opening 151 for the infrared sensor to pass through. The infrared sensor is used to detect the number of rotations of the gears in the gear set 31.

[0048] Thus, after the light emitted by the infrared sensor passes through the opening 151, the number of rotations of the gear set 31 can be obtained by judging the number of teeth, since the teeth of the gear set 31 are discontinuous.

[0049] In other embodiments, the angular displacement detector includes a rotary encoder, which is coaxially connected to the output shaft of the drive component 30. Thus, by directly monitoring the number of rotations of the drive motor output shaft, the number of rotations of the drive component 30 can be directly determined.

[0050] In an optional embodiment, the sensor component further includes a temperature sensor electrically connected to the sensor interface, wherein the temperature sensing end of the temperature sensor contacts the position of the first housing 11 corresponding to the first space 101 to detect the temperature of the grease in the first space 101.

[0051] Thus, if the temperature of the grease is too high, it can easily cause blockage or prevent effective extrusion or lubrication. When the temperature sensor detects that the temperature exceeds the threshold, it also transmits the information remotely to a mobile phone or computer through the communication module.

[0052] Furthermore, a signal indicator light 41 is connected to the control circuit board 40. The signal indicator light 41 is embedded in the second housing 12 and includes multi-color LED lights.

[0053] The system can control the multi-color LEDs to be in different lighting states based on the lubricator's status information. For example, if the grease temperature is abnormal, the control circuit board can light up a yellow light at 40 points; if a blockage occurs, the control circuit board can light up a red light at 40 points; if there is a lack of grease, the control circuit board can light up a yellow light at 40 points and flash it; if the remote module is offline, the control circuit board can light up a red light at 40 points and flash it; if the status is normal, the control circuit board can light up a green light at 40 points; and if the power supply module 50 points are low, the LEDs will turn off.

[0054] In the above embodiments, the communication module includes a 4G / 5G module or a WiFi module soldered to the control circuit board 40. Thus, remote communication can be achieved using the 4G / 5G module or the WiFi module.

[0055] In the above embodiment, a cover 13 is provided at the end of the second housing 12 away from the first housing 11. The cover 13 is used to close the third space 103. When the cover 13 is opened, it can be used to replace the power supply module 50.

[0056] In an optional embodiment, the first housing 11 and the second housing 12 are threaded together by a threaded connection structure 121. When the device is under maintenance, the circuit board, motor, and gear set can be exposed by separating the first housing 11 and the second housing 12 to facilitate repair.

[0057] In conjunction with the above embodiments, the single-point automatic lubricator of this utility model drives the internal piston to move axially through the threaded transmission between the drive component and the screw, so that the grease is extruded in a metered manner. Through the built-in remote communication module, remote grease injection can be realized, and the angular displacement detector can monitor the angular displacement of the drive component. The angular displacement can be used to determine the amount of grease used, the remaining amount, and whether the grease injection port is blocked. As mentioned above, the grease injection of all equipment can be uniformly managed and monitored through the remote control device.

[0058] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
