Description

Technical Field

[0001] This invention relates to the field of bearing waste oil collection technology, specifically to an alarm device for collecting bearing waste oil from a rotating trolley in an annular cooler. Background Technology

[0002] During normal production, as the annular cooler trolley moves, it tilts to unload material when it reaches the unloading port. At this time, the tilting bearing must be well lubricated to ensure smooth tilting of the trolley. Because this type of bearing cannot be lubricated online due to constant movement, manual periodic addition of dry grease has been used. After each lubrication, the waste oil can only be discharged slowly after running for a period of time. Waste oil is discharged from various parts of the tilting bearing end face, causing waste oil to overflow during actual operation, resulting in oil and dust accumulation at the bottom and around the tilting bearing. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a waste oil collection and alarm device for the rotating bearing of an annular cooling machine trolley.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a waste oil collection alarm device for a rotating bearing of a ring-cooled machine trolley, comprising an outer cover covering the outside of the bearing, a V-shaped guide waste oil groove provided below the bearing and corresponding to the inside of the outer cover, a support spring float plate vertically slidably connected to the bottom of the inner cavity of the outer cover, a collector for collecting waste oil in conjunction with the V-shaped guide waste oil groove placed above the support spring float plate, an observation hole corresponding to the oil injection hole opened on the surface of the outer cover, and a bearing side cleaning drive assembly and a deflecting scraper for cleaning waste oil above the bearing rotatably connected inside the observation hole;

[0005] A distance measuring and control mechanism is provided below the supporting spring float. The distance measuring and control mechanism includes a distance measuring device installed below the supporting spring float to monitor the displacement distance, and a controller to control the reciprocating rotation of the bearing side cleaning drive assembly based on the descending displacement. An alarm mechanism is provided below the supporting spring float.

[0006] In the above technical solution, since the bearing is located externally, oiling is convenient. However, prolonged exposure causes waste oil to combine with air dust, forming sludge. The lubricant viscosity is high. Therefore, a V-shaped guide waste oil trough is first installed below the bearing. Due to gravity, the waste oil accumulates at the bottom. The V-shaped guide waste oil trough collects the waste oil, allowing it to fall downwards for unified collection. The outer casing is fixedly connected to the outer wall of the annular cooling machine trolley to prevent dust from adhering to the bearing waste oil. With prolonged use, the amount of waste oil increases. The support spring float plate prevents cleaning problems caused by waste oil removal. The collection device is located on the support spring. Waste oil is collected above the float plate. As the collection volume increases, the weight of the receiver increases, compressing the spring below the supporting spring float plate and causing it to displace downwards. The collection status of the receiver can be determined based on the displacement of the supporting spring float plate. The side cleaning drive assembly and the deflecting scraper on the bearing side enable deflecting and tilting scraping, improving collection efficiency, solving adhesion problems, and making the collection detection of the supporting spring float plate more accurate. At the same time, the supporting spring float plate and the receiver work together to trigger an alarm mechanism. The distance measurement control mechanism, combined with the oil discharge status, controls the deflecting scraper to solve the problem of waste oil discharge collection during the operation of the tilting shaft.

[0007] Based on the above technical solutions, preferably, the alarm mechanism includes a trigger block disposed below the supporting spring float, a trigger switch disposed directly below the trigger block, and an alarm fixedly connected to the outside of the outer casing and corresponding to the trigger switch, the trigger switch triggering the alarm to be activated.

[0008] Based on the above technical solutions, preferably, the deflecting scraper includes a connecting rod, a scraper, several damping rotating rings and limiting pins. The scraper and the connecting rod are rotatably connected through several damping rotating rings. The surface of the damping rotating rings is provided with a rotation limiting groove. The limiting pins are fixedly connected to the surface of the connecting rod in pairs, and the limiting pins are located inside the rotation limiting grooves.

[0009] Based on the above technical solutions, preferably, two deflecting obstruction pins are fixedly connected to the inner wall of the bearing hole, and a spring telescopic rod is provided at the top of the connecting rod. When the spring telescopic rod is not elastically deformed, the scraper is in inclined contact with the bearing surface.

[0010] In the above technical solution, the scraper swings left and right above the bearing surface with the connecting rod, with each swing not exceeding two bearings and two side plates. Since the spring telescopic rod is not in an elastic deformation state, the scraper is in inclined contact with the bearing surface. When the scraper tilts and rotates to the deflection blocking pin, it continues to rotate. At this time, the spring telescopic rod undergoes a compression reaction. After the scraper rotates to vertical, it tilts to the other side under the influence of the deflection blocking pin. The damping rotating ring has a certain rotational damping. The bearing side cleaning drive assembly switches the rotation direction. At this time, the scraper tilts in the same direction as the rotation direction. The scraper separates from the deflection blocking pin, the spring telescopic rod resets, and the scraper naturally tilts and adheres to the bearing side. The deflection is achieved by the rotation limiting groove cooperating with the limiting pin. At this time, the tilted scraper sweeps the inclined surface. When rotating, it scrapes the waste oil above the bearing side. Affected by the reaction force, the waste oil is guided by the inclined surface of the scraper and falls into the V-shaped guide waste oil groove.

[0011] Based on the above technical solutions, preferably, the bearing side cleaning drive assembly includes a main ring, an extension rod, and a connecting ring. The main ring is rotatably connected to the inside of the observation hole on the outer casing. The main ring is fixedly connected to the connecting ring through several extension rods. The centers of the main ring and the connecting ring are both located on the same horizontal line as the center of the oil injection hole. The inner diameters of the connecting ring and the main ring are both larger than the inner diameter of the oil injection hole. The connecting ring does not contact the bearing sidewall.

[0012] Based on the above technical solutions, preferably, a toothed ring is fixedly connected to the periphery of the main ring, the outer casing has a transmission cavity inside to accommodate the rotation of the toothed ring, a drive motor is also provided at the bottom of the transmission cavity, a transmission belt is provided between the drive motor and the toothed ring, the drive motor and the toothed ring are connected by transmission through the transmission belt, and the controller is signal connected to the drive motor.

[0013] In the above technical solution, the rotation of the bearing side cleaning drive assembly should not affect the oil injection operation of the oil injection hole. The main ring is set on the outside and rotates in conjunction with the observation hole. The connecting ring extends to a position close to the bearing through the extension rod. The connecting rod is fixedly connected to the connecting ring, so that the scraper can act on the side of the bearing. However, the rotation of the main ring requires power. Therefore, the toothed ring is set on the outside of the main ring. A transmission cavity is opened on the outer wall of the outer casing so that the toothed ring rotates in the cavity. The output end of the drive motor is linked through gears, toothed rings and transmission belt. The angle of each left and right rotation of the drive motor can be adjusted by the controller.

[0014] Based on the above technical solutions, preferably, the outer casing is provided with an on / off counter for recording the number of times the drive motor is turned on.

[0015] Based on the above technical solutions, preferably, a recorder for recording maintenance cycles is fixedly connected to the outside of the outer casing.

[0016] In the above technical solution, the collection speed of waste oil can be calculated by the number of times the opening and closing counter is used, so as to facilitate the observation of the discharge status of waste oil. The recorder is mainly used to meet the equipment maintenance management record system and facilitate traceability.

[0017] Based on the above technical solutions, preferably, both sides of the outer casing are fixedly connected with fixing lugs for fixing, and the side of the outer casing is provided with a side door for collecting the storage device. The device is fixed to the outside of the bearing and surrounded by the fixing lugs, and the storage device can be replaced by opening the side door.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. While meeting the requirements for oil injection on the rotating shaft of the ring cooler trolley, the problem of waste oil collection has been solved. In addition, the problem of waste oil accumulation on the bearing sidewall caused by the protrusion of the rotating shaft is addressed by using a deflecting scraper to achieve deflecting and tilting scraping, thereby improving collection efficiency, solving the adhesion problem, and making the collection and detection of the support spring float plate more accurate.

[0020] 2. The alarm mechanism is activated by using a support spring float plate and a collection device. The special control of the deflector scraper is achieved by using a distance measurement control mechanism combined with the oil discharge status. This solves the problem of collecting waste oil discharge when the tilting shaft is working, improves the convenience of equipment maintenance, and increases the cleanliness of the working environment.

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, the present invention discloses a waste oil collection alarm device for a rotating bearing of a trolley in a ring-cooled machine. It includes an outer casing 1 covering the bearing, a V-shaped waste oil guide groove 4 located below the bearing and corresponding to the interior of the outer casing 1, a support spring float 5 vertically slidably connected to the bottom of the inner cavity of the outer casing 1, a collector 6 for collecting the waste oil in conjunction with the V-shaped guide groove 4 placed above the support spring float 5, an observation hole 12 corresponding to the oil injection hole on the surface of the outer casing 1, and a bearing side cleaning drive assembly 2 for cleaning waste oil above the bearing and a deflecting scraper 3 rotatably connected inside the observation hole 12. A distance measuring control mechanism 8 is located below the support spring float 5, including a distance meter 81 located below the support spring float 5 to monitor displacement distance and a controller 82 that controls the reciprocating rotation of the bearing side cleaning drive assembly 2 based on the descending displacement. An alarm mechanism 7 is located below the support spring float 5.

[0030] Because the bearing is located externally, lubrication is convenient. However, prolonged exposure causes waste oil to combine with airborne dust, forming sludge. Since the lubricant has a high viscosity, a V-shaped waste oil guide trough 4 is first installed below the bearing. Due to gravity, the waste oil accumulates at the bottom. The V-shaped guide trough 4 collects the waste oil, allowing it to fall to the bottom for unified collection. The outer casing 1 is fixedly connected to the outer wall of the annular cooling machine trolley to prevent dust from adhering to the bearing waste oil. With prolonged use, the amount of waste oil increases. A support spring float 5 is installed to prevent cleaning problems caused by waste oil removal. The collector 6 is located on the support spring float 5. Waste oil is collected above the container. As the amount collected increases, the weight of the container 6 increases, compressing the spring below the supporting spring float 5 and causing the supporting spring float 5 to move downwards. The collection status of the container 6 can be determined based on the displacement of the supporting spring float 5. The side cleaning drive assembly 2 and the deflecting scraper 3 are used to achieve deflecting and tilting scraping, improving collection efficiency, solving the adhesion problem, and making the collection detection of the supporting spring float 5 more accurate. At the same time, the supporting spring float 5 and the container 6 work together to trigger an alarm mechanism 7. The distance control mechanism 8 is used in conjunction with the oil discharge status to control the deflecting scraper 3, solving the problem of waste oil discharge collection when the flip shaft is working.

[0031] The rangefinder 81 is located below the support spring float 5. The rangefinder 81 is a laser rangefinder. Based on the maximum deformation of the spring in the support spring float 5, the maximum compression stroke of the spring is divided into n small segments. According to the data collected by the rangefinder 81, the controller 82 controls the bearing side cleaning drive assembly 2 and the deflecting scraper 3 to clean the upper part of the bearing side whenever the stroke is reduced by a small segment.

[0032] In a preferred embodiment, the deflecting scraper 3 includes a connecting rod 31, a scraper 32, several damping rotating rings 34, and limiting pins 35. The scraper 32 and the connecting rod 31 are rotatably connected through several damping rotating rings 34. The surface of the damping rotating rings 34 is provided with a rotation limiting groove 341. The limiting pins 35 are fixedly connected to the surface of the connecting rod 31 in pairs, and the limiting pins 35 are located inside the rotation limiting grooves 341. Two deflecting obstruction pins 36 are fixedly connected to the inner side wall of the bearing hole. A spring telescopic rod 33 is provided at the top of the connecting rod 31. When the spring telescopic rod 33 is not elastically deformed, the scraper 32 is in inclined contact with the bearing surface.

[0033] Scraper 32 swings left and right above the bearing surface with connecting rod 31, each swing not exceeding two bearings and two side plates. Since spring telescopic rod 33 is not in an elastically deformed state, scraper 32 is in inclined contact with the bearing surface. When scraper 32 rotates to the deflection blocking pin 36, it continues to rotate, at which point spring telescopic rod 33 undergoes a compression reaction. After scraper 32 rotates to vertical, it is affected by the deflection blocking pin 36 and tilts to the other side. Damping rotating ring 34 has a certain rotational damping, and the bearing side cleaning drive... When the rotating component 2 switches the rotation direction, the scraper 32 tilts in the same direction as the rotation direction. The scraper 32 separates from the deflection blocking pin 36, the spring telescopic rod 33 resets, and the scraper 32 naturally tilts and fits against the side of the bearing. The deflection is achieved by the rotation limiting groove 341 cooperating with the limiting pin 35. At this time, the inclined scraper 32 sweeps the inclined surface. When rotating, it scrapes the waste oil above the side of the bearing. Affected by the reaction force, the waste oil is guided by the inclined surface of the scraper 32 and falls into the V-shaped guide waste oil groove 4.

[0034] In a preferred embodiment, the bearing side cleaning drive assembly 2 includes a main ring 21, an extension rod 22, and a connecting ring 23. The main ring 21 is rotatably connected to the inside of the observation hole 12 on the outer casing 1. The main ring 21 is fixedly connected to the connecting ring 23 through several extension rods 22. The centers of the main ring 21 and the connecting ring 23 are both on the same horizontal line as the center of the oil injection hole. The inner diameters of the connecting ring 23 and the main ring 21 are both larger than the inner diameter of the oil injection hole. The connecting ring 23 does not contact the bearing sidewall. A toothed ring 211 is fixedly connected to the circumference of the main ring 21. The outer casing 1 has a transmission cavity 15 inside to accommodate the rotation of the toothed ring 211. A drive motor 25 is also provided at the bottom of the transmission cavity 15. A transmission belt 24 is provided between the drive motor 25 and the toothed ring 211. The drive motor 25 and the toothed ring 211 are connected by transmission through the transmission belt 24. The controller 82 is connected to the drive motor 25 by signal.

[0035] The rotation of the bearing side cleaning drive assembly 2 should not affect the oil filling operation of the oil filling hole. The main ring 21 is set on the outside and rotates in conjunction with the observation hole 12. The connecting ring 23 extends to a position close to the bearing through the extension rod 22. The connecting rod 31 is fixedly connected to the connecting ring 23, so that the scraper 32 can act on the side of the bearing. However, the rotation of the main ring 21 requires power. Therefore, a toothed ring 211 is set on the outside of the main ring 21. A transmission cavity 15 is opened on the outer wall of the outer cover 1 so that the toothed ring 211 rotates in the cavity. The output end of the drive motor 25 is linked through the gear, the toothed ring 211 and the transmission belt 24. The angle of each left and right rotation of the drive motor 25 can be adjusted by the controller 82.

[0036] In a preferred embodiment, the outer casing 1 is provided with an on / off counter 251 for recording the number of times the drive motor 25 is turned on, and a recorder 14 for recording the maintenance cycle is fixedly connected to the outer casing 1. The collection speed of waste oil can be calculated by the number of times the on / off counter 251 is turned on, so as to facilitate the observation of the discharge status of waste oil. The recorder 14 is mainly for the equipment maintenance management recording system to facilitate traceability.

[0037] In a preferred embodiment, the alarm mechanism 7 includes a trigger block 71 disposed below the supporting spring float 5, a trigger switch 72 disposed directly below the trigger block 71, and an alarm 73 fixedly connected to the outside of the outer casing 1 corresponding to the trigger switch 72. The trigger switch 72 triggers and activates the alarm 73. Although the scratch situation can be recorded by the on / off counter 251, the overflow alarm of the storage container 6 cannot be realized. Therefore, the trigger block 71 and the trigger switch 72 are disposed below the supporting spring float 5. After the supporting spring float 5 descends to its limit position, the trigger block 71 contacts the trigger switch 72 and activates the alarm. The alarm 73 then sounds, prompting maintenance personnel to come and clean the container. After cleaning, the maintenance cycle is recorded by the recorder 14.

[0038] In a preferred embodiment, both sides of the outer casing 1 are fixedly connected with fixing lugs 11 for fixing, and the side of the outer casing 1 is provided with a side door 13 for collecting the storage device 6. The device is fixed to the outside of the bearing by the fixing lugs 11 and can be replaced by opening the side door 13.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
