Description

Technical Field

[0001] The invention belongs to the field of single-point lubrication of mechanical equipment, and specifically relates to a single-point lubrication device for mechanical equipment. Background Art

[0002] The cement industry has high requirements for equipment lubrication, especially for rotating equipment such as bearings and motors of mechanical equipment involved in rotary kilns and coal mills. In the existing technology, the lubrication status of cement companies on equipment is very poor. More than 60% of equipment failures are caused by poor lubrication, and more than 80% of abnormal parts loss is caused by abnormal wear caused by poor lubrication.

[0003] The reason for the above situation is that most of the lubrication points in the cement industry are still manually filled by operators. Operators add lubricating grease by manually applying or using grease pumps and grease guns. The manual application method also requires the equipment to be dismantled for filling lubricating grease. There are many lubrication points on the production site, and the workload of manual lubrication is large, which increases the cost of manual production. In high places, dangerous areas and rotating equipment areas, operators are highly dangerous and risky when filling, and safety accidents are prone to occur. There is a lack of effective supervision on the use of oil according to quality in different lubrication parts. It all depends on the experience and responsibility of the operators. It is impossible to ensure timely and effective lubrication of the equipment and the strict implementation of lubrication tasks. As a result, the use of manual filling mode often results in insufficient lubrication and excessive lubrication problems. Grease is often missed, which leads to increased bearing loss, and then causes bearing failure, downtime or even kiln shutdown accidents, causing huge losses to the normal production of the cement plant.

[0049] like Fig.12 As shown, the single-point lubrication device for mechanical equipment provided by the present invention also includes a locking ring 30, which is used to lock and connect the oil cup body 11 and the base 21. A threaded groove 31 adapted to the threaded protrusion 112 is provided on the inner wall of the locking ring 30, and the locking ring 31 is connected to the oil cup body 11 through threaded cooperation between the threaded groove 31 and the threaded protrusion 112. A second locking flange 32 adapted to the first locking flange 211 is provided on the edge of one side of the locking ring 31 close to the base 21. The second locking flange 32 is annular. When the locking ring 30 is connected to the oil cup body 11, the threaded protrusion 112 is screwed into the threaded groove 31, and the second locking flange 32 abuts against the first locking flange 211, thereby pressing the base 21 onto the oil cup body 11, which can avoid relative rotation between the base 21 and the oil cup body 11, and ensure the stability and reliability of the lubricating grease filling process. The oil cup body 11 and the base 21 are connected by the locking ring 30, which facilitates assembly and disassembly, and facilitates replenishing the lubricating grease in the oil cup body 11 after the lubricating grease stored in the oil cup body 11 is exhausted.

The counting gear 41 is provided with a ratchet 44, and eight ratchet teeth 44 are evenly arranged on the counting gear 41. When the counting gear 41 rotates, the ratchet 44 abuts against the driving rod 43 and triggers the micro switch 42. Every time the counting gear 41 rotates one circle, the rotating screw 23 rotates 360°, driving the push seat 12 to move downward a fixed distance. During the process of the counting gear 41 rotating one circle, the eight ratchets 44 trigger the micro switch 42 once respectively. The micro switch 42 uploads an electrical signal every eight times it is triggered, thereby facilitating the control of the filling amount and filling cycle of the lubricating grease, avoiding the situation of over-filling or under-filling of the lubricating grease, avoiding the waste of lubricating grease, and reducing the labor cost of filling the lubricating grease.

[0056] Fig.16 It is a structural schematic diagram of a power supply, a PCB control circuit board and a connection module in an oil injection structure in an embodiment of the present invention.

[0057] like Fig.16 As shown, the oil filling structure 20 also includes a power supply 24, a PCB control circuit board 25 and a connection module 26. The power supply 24 is connected to the PCB control circuit board 25, and the PCB control circuit board 25 is connected to the drive motor 22, so that the power supply 24 can provide power for the drive motor 22 and the PCB control circuit board 25, ensuring that the drive motor 22 and the PCB control circuit board 25 can work normally. The power supply 24 uses a dry battery, which is convenient for replacement. The PCB control circuit board 25 is connected to the micro switch 42, and the PCB control circuit board 25 can receive the electrical signal uploaded by the micro switch 42.

One end of the clamping spring 28 is connected to the pressure cover 27, and the other end is connected to the protective cover 50. The clamping spring 28 is in a compressed state, thereby pressing the pressure cover 27 against the base 21, further preventing dust and other impurities from entering the interior of the base 21 and damaging components, thereby further improving the reliability and service life of the structure.

[0061] like Fig.12 As shown, the locking ring 30 is provided with an alignment flange 33, the alignment flange 33 is provided with an alignment notch 34, the inner wall of the protective cover 50 is provided with an alignment protrusion 51 adapted to the alignment notch 34, and the alignment protrusion 51 is clamped in the alignment notch 34, so that the protective cover 50 is clamped on the locking ring 30 for easy disassembly.

[0062] like Figure 4 As shown, a first mounting groove 114 is provided on the oil cup body 11, and a first sealing ring 60 is provided in the first mounting groove 114. The first sealing ring 60 is located between the oil cup body 11 and the protective cover 50, which can further enhance the sealing performance, prevent dust and other impurities from entering and damaging components, and improve the reliability and service life of the structure.

[0063] like Figure 6 As shown, a second mounting groove 124 is provided on the push seat 12, and two second mounting grooves 124 are distributed on the edge of the push seat 12. A second sealing ring 70 is provided in each of the two second mounting grooves 124. The second sealing ring 70 is located between the push seat 12 and the inner wall of the oil cup body 11, which can enhance the sealing between the push seat 12 and the oil cup body 11, prevent the lubricating grease from leaking from between the push seat 12 and the oil cup body 11, ensure that the lubricating grease can be smoothly pressed out from the threaded connector 111, and improve the stability of the lubricating grease filling.

[0064] like Figure 1 and 3 As shown, a connecting seat 80 is provided on the end of the oil cup body 11 away from the oil filling structure 20. The connecting seat 80 is funnel-shaped and is connected to the threaded connector 111 by threaded cooperation. An extension joint 81 is provided on the connecting seat 80. The connecting seat 80 is installed on the lubrication point of the production equipment through the extension joint 81, so as to facilitate the connection between the single-point lubrication device for mechanical equipment provided by the present invention and the lubrication point of the production equipment, and facilitate disassembly and assembly.

[0065] When the single-point lubrication device for mechanical equipment provided by the present invention is used to add lubricating grease, the lubricating grease is added into the oil cup body 11, the push seat 12 is pressed into the oil cup body 11, the rotating screw 23 is screwed into the threaded hole 122 of the push seat 12, the base 21 is installed, and the hexagonal protrusion 231 at one end of the rotating screw 23 is connected to the second connecting groove 412 of the counting gear 41, thereby connecting the rotating screw 23 and the motor shaft of the driving motor 22, the positioning protrusion 214 on the base 21 is clamped in the positioning groove 113 on the edge of the oil cup body 11, and the locking ring is fixed. 30 is sleeved on the oil cup body 11 from one end of the base 21, and the threaded protrusion 112 is screwed into the threaded groove 31, so that the first locking flange 211 of the base 21 and the second locking flange 32 of the locking ring 30 are abutted, thereby pressing the base 21 onto the oil cup body 11, and installing the protective cover 50 on the locking ring 30. After assembling the single-point lubrication device for mechanical equipment, it is connected to the connecting seat 80 through the threaded connector 111 on the oil cup body 11, thereby connecting the lubrication points of the production equipment, facilitating automatic filling of lubricating grease, and helping to reduce labor costs.

[0066] During the process of filling lubricating grease, the PCB control circuit board 25 controls the driving motor 22 to start, and the driving motor 22 drives the rotating screw 23 to rotate through the counting gear 41. The counting gear 41 and the rotating screw 23 rotate synchronously, and the rotational motion of the rotating screw 23 is converted into the linear motion of the push seat 12, thereby squeezing the lubricating grease in the oil cup body 11 out of the threaded connector 111. When the counting gear 41 rotates, the ratchet 44 abuts against the driving rod 43 and triggers the micro switch 42. Every time the counting gear 41 rotates one circle, the rotating screw 23 rotates 360°, driving the push seat 12 to move downward a fixed distance. During the process of the counting gear 41 rotating one circle, the eight ratchets 44 trigger the micro switch 42 once respectively. The micro switch 42 uploads an electrical signal every eight times it is triggered. The PCB control circuit board 25 can receive the electrical signal uploaded by the micro switch 42. Since the rotating screw 23 rotates 360° every time the counting gear 41 rotates one circle, the downward distance of the push seat 12 is fixed, and the diameter of the oil cup body 11 is also fixed. Therefore, every time the counting gear 41 rotates one circle, the amount of lubricating grease squeezed out is certain, thereby facilitating the control of the lubricating grease filling amount and filling cycle.

[0067] The actual daily lubricant consumption of the production equipment is determined through the actual situation at the production site and the specifications of the production equipment, so that the operation of the drive motor 22 can be controlled conveniently through the PCB control circuit board 25, so that the drive motor 22 can start rotating at a fixed time every day, and drive the counting gear 41 and the rotating screw 23 to rotate a fixed number of circles, so as to control the lubricant filling amount and filling cycle, avoid the situation of too much or too little lubricant filling, avoid lubricant waste, and reduce the labor cost of filling lubricant.

[0070] When the single-point lubrication device for mechanical equipment provided by the present invention is used to add lubricating grease, the lubricating grease is added into the oil cup body 11, the push seat 12 is pressed into the oil cup body 11, the rotating screw 23 is screwed into the threaded hole 122 of the push seat 12, the base 21 is installed, and the hexagonal protrusion 231 at one end of the rotating screw 23 is connected to the second connecting groove 412 of the counting gear 41, thereby connecting the rotating screw 23 and the motor shaft of the driving motor 22, the positioning protrusion 214 on the base 21 is clamped in the positioning groove 113 on the edge of the oil cup body 11, and the locking ring is fixed. 30 is sleeved on the oil cup body 11 from one end of the base 21, and the threaded protrusion 112 is screwed into the threaded groove 31, so that the first locking flange 211 of the base 21 and the second locking flange 32 of the locking ring 30 are abutted, thereby pressing the base 21 onto the oil cup body 11, and installing the protective cover 50 on the locking ring 30. After assembling the single-point lubrication device for mechanical equipment, it is connected to the connecting seat 80 through the threaded connector 111 on the oil cup body 11, thereby connecting the lubrication points of the production equipment, facilitating automatic filling of lubricating grease, and helping to reduce labor costs.

[0071] During the process of filling lubricating grease, the PCB control circuit board 25 controls the driving motor 22 to start, and the driving motor 22 drives the rotating screw 23 to rotate through the counting gear 41. The counting gear 41 and the rotating screw 23 rotate synchronously, and the rotational motion of the rotating screw 23 is converted into the linear motion of the push seat 12, thereby squeezing the lubricating grease in the oil cup body 11 out of the threaded connector 111. When the counting gear 41 rotates, the ratchet 44 abuts against the driving rod 43 and triggers the micro switch 42. Every time the counting gear 41 rotates one circle, the rotating screw 23 rotates 360°, driving the push seat 12 to move downward a fixed distance. During the process of the counting gear 41 rotating one circle, the eight ratchets 44 trigger the micro switch 42 once respectively. The micro switch 42 uploads an electrical signal every eight times it is triggered. The PCB control circuit board 25 can receive the electrical signal uploaded by the micro switch 42. Since the counting gear 41 rotates one circle, the rotating screw 23 rotates 360°, the downward distance of the push seat 12 is fixed, and the diameter of the oil cup body 11 is also fixed. Therefore, every time the counting gear 41 rotates one circle, the amount of lubricating grease squeezed out is certain, which facilitates the PCB control circuit board 25 to control the number of rotations and the rotation timing of the counting gear 41 and the rotating screw 23 according to the electrical signal uploaded by the micro switch 42, thereby facilitating the control of the lubricating grease filling amount and filling cycle.

[0072] The actual daily lubricant consumption of the production equipment is determined through the actual situation at the production site and the specifications of the production equipment, so that the operation of the drive motor 22 can be controlled conveniently through the PCB control circuit board 25, so that the drive motor 22 can start rotating at a fixed time every day, and drive the counting gear 41 and the rotating screw 23 to rotate a fixed number of circles, so as to control the lubricant filling amount and filling cycle, avoid the situation of too much or too little lubricant filling, avoid lubricant waste, and reduce the labor cost of filling lubricant.

[0073] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
