Description

Technical Field

[0001] This utility model belongs to the field of centrifuge maintenance technology, and specifically relates to a device that facilitates the maintenance of centrifuge drive components. Background Technology

[0002] Centrifuges, as key equipment capable of solid-liquid separation and particle classification at high speeds, play an irreplaceable role in many industrial fields, such as petrochemicals, biopharmaceuticals, environmental wastewater treatment, and food processing. The bearing housing in its drive assembly is one of the core hubs of the entire centrifuge system.

[0003] During the long-term continuous operation of a centrifuge, the high-speed rotation generated during centrifuge operation causes the main bearing to be subjected to enormous centrifugal force. At the same time, mechanical vibration and alternating stress under complex working conditions also continuously act on the main shaft. Over time, the main shaft is prone to wear, fatigue cracks and other damage, so it is necessary to regularly remove the main shaft from the bearing housing for inspection and maintenance.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a device that facilitates the maintenance of centrifuge drive components, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a device for facilitating the maintenance of a centrifuge drive assembly, comprising a base, a connecting frame fixedly mounted at one end of the base, an angle rotation mechanism within the connecting frame, multiple screws fixedly mounted on the top of the angle rotation mechanism, a pull rod slidably mounted on the side of the base away from the connecting frame, a bidirectional drive mechanism mounted on the pull rod, and spindle clamps symmetrically threaded onto the bidirectional drive mechanism, two spindle clamps slidably mounted on the pull rod, the two spindle clamps forming a ring, multiple circular holes on each of the two spindle clamps, and hydraulic cylinders symmetrically mounted at one end of the pull rod, both hydraulic cylinders being fixedly mounted on the base.

[0008] Furthermore, the angle rotation mechanism includes a drive motor, which is fixedly mounted on the connecting frame, and a rotating shaft is fixedly mounted on the output end of the drive motor.

[0009] Furthermore, the rotating shaft passes through the top of the connecting frame and extends upwards, and an angle turntable is fixedly installed on the top of the rotating shaft and above the connecting frame.

[0010] Furthermore, the bidirectional drive mechanism includes a servo motor, which is fixedly mounted on the pull rod, and the output shaft of the servo motor is fixedly mounted with a bidirectional threaded rod.

[0011] Furthermore, the threads on the bidirectional threaded rod are symmetrical and opposite, and the other end of the bidirectional threaded rod is rotatably mounted on the pull rod.

[0012] Furthermore, the two spindle clamps are respectively threaded onto the two threads of the bidirectional threaded rod, and semi-circular washers are fixedly installed on the inner rings of the two spindle clamps.

[0013] Furthermore, support seats are fixedly installed at both ends of the bottom of the base, and sliding grooves are provided on the base for the pull rod to slide.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a bidirectional drive mechanism. Since two spindle clamps are slidably mounted on the pull rod, the bidirectional drive mechanism simultaneously moves the two threaded spindle clamps toward the spindle of the bearing housing, ensuring a tight grip on the spindle. Then, two hydraulic cylinders are activated, pulling the pull rod away from the connecting frame. The pull rod then moves the two spindle clamps. Because the spindle clamps are already tightly gripping the spindle, the sliding of the pull rod separates the bearing housing from the spindle, allowing for maintenance of the bearing housing's spindle. This significantly improves maintenance efficiency and reduces the workload of maintenance personnel.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0027] Please see Figures 1-5 As shown, this utility model is a device for facilitating the maintenance of centrifuge drive components, including a base 1. A connecting frame 2 is fixedly installed at one end of the base 1. An angle rotation mechanism 3 is provided inside the connecting frame 2. Multiple screws 4 are fixedly installed on the top of the angle rotation mechanism 3. A pull rod 5 is slidably provided on the side of the base 1 away from the connecting frame 2. A bidirectional drive mechanism 6 is provided on the pull rod 5. A spindle clamp 7 is symmetrically threaded on the bidirectional drive mechanism 6. Two spindle clamps 7 are slidably installed on the pull rod 5. The two spindle clamps 7 can form a ring. Multiple circular holes 701 are opened on both spindle clamps 7. Hydraulic cylinders 8 are symmetrically installed at one end of the pull rod 5. Both hydraulic cylinders 8 are fixedly installed on the base 1.

[0028] When the bearing housing needs to be repaired, first place the bearing housing as a whole on the angle rotation mechanism 3, then align the multiple mounting holes on the bearing housing with the multiple screws 4, and pass them through the screws 4. Then use nuts to tighten them one by one onto the multiple screws 4, thereby fixing the bearing housing to the angle rotation mechanism 3 with nuts and screws 4.

[0029] During maintenance, if the main shaft on the bearing housing needs to be disassembled for maintenance, first, the angle rotation mechanism 3 is activated to rotate, causing the angle rotation mechanism 3 to rotate and drive the bearing housing, which is already fixed on it, to rotate. Rotation is stopped when the main shaft on the bearing housing is aligned with the midpoint between the two main shaft clamps 7. Then, the two hydraulic cylinders 8 are simultaneously activated to push the pull rod 5 on the base 1 towards the connecting frame 2. The pull rod 5 then moves the two slidingly mounted main shaft clamps 7 until they reach the main shaft on the bearing housing. At this point, the two hydraulic cylinders 8 stop working. Then, the bidirectional drive mechanism 6 rotates. Since the two main shaft clamps 7 are slidably mounted on the pull rod 5, the bidirectional drive mechanism 6 drives the two threaded main shaft clamps 7 to move simultaneously towards the main shaft of the bearing housing, allowing them to... The spindle is tightly gripped, and multiple bolts are passed through the multiple round holes 701 on the two spindle clamps 7 one by one, and then tightened to the bolts with nuts. This makes the two spindle clamps 7 more secure. It is important to note that since the two spindle clamps 7 are threaded onto the bidirectional drive mechanism 6, the two spindle clamps 7 will no longer move relative to each other. The bolts and nuts are added to make the pulling direction of the two spindle clamps 7 more secure when pulling the spindle of the bearing housing. Then, the two hydraulic cylinders 8 are activated to pull the pull rod 5 away from the connecting frame 2. The pull rod 5 will drive the two spindle clamps 7 to move. Since the spindle clamps 7 have gripped the spindle, as the pull rod 5 slides, the bearing housing can be separated from the spindle, thereby allowing the spindle of the bearing housing to be inspected and repaired. This greatly improves the inspection efficiency and reduces the workload of maintenance personnel.

[0030] In one embodiment, the angle rotation mechanism 3 includes a drive motor 301, which is fixedly mounted on the connecting frame 2, and a rotating shaft 302 is fixedly mounted on the output end of the drive motor 301.

[0031] The rotating shaft 302 passes through the top of the connecting frame 2 and extends upwards. An angle turntable 303 is fixedly installed on the top of the rotating shaft 302 and above the connecting frame 2.

[0032] When maintenance requires disassembling the spindle on the bearing housing, first start the drive motor 301. The drive motor 301 will rotate, causing the connected rotating shaft 302 to rotate, which in turn causes the angle turntable 303 to start rotating, causing the bearing housing, which is securely mounted on it, to rotate together. During this process, when the spindle on the bearing housing is accurately aligned with the middle position between the two spindle clamps 7, immediately stop the drive motor 301. At this time, the angle turntable 303 and the bearing housing will stop rotating.

[0033] In one embodiment, the bidirectional drive mechanism 6 includes a servo motor 601, which is fixedly mounted on the pull rod 5, and the output shaft of the servo motor 601 is fixedly mounted with a bidirectional threaded rod 602.

[0034] The threads on the bidirectional threaded rod 602 are symmetrical and opposite, and the other end of the bidirectional threaded rod 602 is rotatably mounted on the pull rod 5.

[0035] The two main shaft clamps 7 are respectively threaded onto the two threads of the bidirectional threaded rod 602, and a semi-circular washer 702 is fixedly installed on the inner ring of each of the two main shaft clamps 7.

[0036] Both ends of the base 1 are fixedly installed with support seats 101, and the base 1 is provided with sliding grooves 102 for the pull rod 5 to slide.

[0037] The support seats 101 fixedly installed at both ends of the bottom of the base 1 provide stable support for the entire equipment. Based on the above working principle, the two hydraulic cylinders 8 installed on the base 1 are then activated simultaneously. The base 1 has a sliding groove 102 for the pull rod 5 to slide. The hydraulic cylinders 8 start working, generating thrust to push the pull rod 5 to slide in the sliding groove 102 towards the connecting frame 2. During the movement of the pull rod 5, the two main shaft clamps 7 slidably installed on it move forward synchronously. When the two main shaft clamps 7 move to the position of the main shaft on the bearing box... Immediately stop the operation of the two hydraulic cylinders 8, then start the servo motor 601. Its output shaft is fixedly connected to the bidirectional threaded rod 602. The threads on the bidirectional threaded rod 602 are symmetrical and opposite, and the other end is rotatably mounted on the pull rod 5. The two spindle clamps 7 are respectively threaded onto the two threads of the bidirectional threaded rod 602 with different directions of rotation. When the servo motor 601 starts running, it drives the bidirectional threaded rod 602 to rotate, so that the two spindle clamps 7 can simultaneously move towards the spindle of the bearing housing. Furthermore, both inner rings of the two spindle clamps 7 are... A semi-circular washer 702 is fixedly installed. The semi-circular washer 702 increases the friction between the spindle clamp 7 and the spindle, helping to grip the spindle more tightly and stably. After the two spindle clamps 7 tightly grip the spindle, multiple bolts are sequentially passed through the multiple round holes 701 on the two spindle clamps 7 and tightened with nuts, making the connection between the two spindle clamps 7 more stable. Moreover, since the two spindle clamps 7 are threaded onto the double-threaded rod 602, the two spindle clamps 7 will not move relative to each other during subsequent operations, increasing the thread... The bolts and nuts ensure that the two spindle clamps 7 are more secure in the pulling direction when the spindle of the bearing housing is pulled. Finally, the two hydraulic cylinders 8 are activated again to pull the pull rod 5 away from the connecting frame 2 and move it in the sliding groove 102. The pull rod 5 drives the two spindle clamps 7 to move synchronously. Since the spindle clamps 7 have tightly gripped the spindle, the bearing housing can be separated from the spindle as the pull rod 5 slides, thereby enabling the maintenance of the spindle of the bearing housing. This greatly improves maintenance efficiency and reduces the workload of maintenance personnel.
