Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge maintenance, in particular to a processing tool that can be used for centrifuge maintenance. Background Art

[0002] A centrifuge is a machine that uses centrifugal force as a driving force to separate or concentrate suspensions, emulsions and other materials. Centrifuges are widely used in many fields such as chemical industry, petroleum, food, pharmaceuticals, mineral processing, coal, water treatment, shipping, biochemistry, genetic engineering, agriculture and forestry, hospitals, etc.

[0003] Chinese patent CN202220777473.2 discloses a centrifuge accessory repair tool. The patent uses a rotating knob to control two arc-shaped pressure plates to push toward the side close to the accessory until the accessory is clamped. When the accessory has an irregular surface and is difficult to clamp, the angle of the arc-shaped pressure plate is adjusted by cooperating with the motor and gear to achieve stable tightening of the irregular accessory.

[0004] However, this patent only solves the problem of clamping accessories during centrifuge maintenance. The problem that maintenance workers need to bend over for a long time when repairing the centrifuge still exists. The maintenance workers will bend over for a long time when repairing the centrifuge, which will cause the waist muscles to be in a tense state for a long time, which is prone to occupational diseases such as lumbar muscle strain. Therefore, the maintenance workers of the centrifuge must stop to relieve waist discomfort after working for a period of time, which greatly reduces the maintenance efficiency. At the same time, it is easy to interrupt the maintenance process midway, resulting in poor maintenance quality. Therefore, there is an urgent need for a centrifuge processing tool that allows maintenance workers to perform maintenance at a comfortable angle. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-5 , a processing tool that can be used for centrifuge maintenance, including a base 7, a guide ring 1 is fixedly connected to the top of the base 7, a sliding groove 16 is opened inside the guide ring 1, and a rotating gear ring 9 is slidably connected inside the sliding groove 16, and the sliding groove 16 can provide support and guidance for the sliding of the rotating gear ring 9, and the outer wall of the rotating gear ring 9 is fixedly connected to a rack and distributed in a ring array along the outer wall, and the inner wall of the rotating gear ring 9 is fixedly connected to a bearing plate 13, which is used to fix the centrifuge to be repaired. The top of the base 7 is located on both sides of the guide ring 1 and is bolted to a drive motor 6. Since the size of the rotating gear ring 9 is relatively large and it needs to be continuously rotated forward and reversed during the maintenance process, it is confirmed according to actual work tests that it is unrealistic to use the rotating motor 6 to continuously rotate forward and reverse to adjust the forward and reverse rotation of the rotating gear ring 9. Therefore, the functions of the two drive motors 6 are not the same. The clockwise rotation of one of the drive motors 6 can make the rotating gear ring 9 rotate counterclockwise, while the counterclockwise rotation of the other drive motor 6 can make the rotating gear ring 9 rotate clockwise. The output end of the drive motor 6 is connected to the drive gear 2 through a coupling transmission. Both sides of the drive gear 2 are rotatably connected to the base 7 through gear brackets 8. The gear brackets 8 on both sides of the drive gear 2 provide support for the gear, wherein the drive gear 2 and the two gear brackets 8 are rotatably connected through a rotating shaft. The drive gear 2 passes through the guide ring 1 through a square groove 18 opened on one side of the guide ring 1, and the drive gear 2 is engaged with the teeth on the outer wall of the rotating gear ring 9 in the inner cavity of the guide ring 1 through the teeth on the surface wall. The two drive gears 2 are engaged with the teeth on the outer wall of the rotating gear ring 9, but no matter whether the rotating gear ring 9 rotates counterclockwise or clockwise, only one drive gear 2 drives the rotating gear ring 9.

[0024] Furthermore, a plurality of T-shaped limit grooves 12 are provided on the top of the supporting plate 13, and the plurality of T-shaped limit grooves 12 are provided parallel to each other. A trolley plate 3 is provided on the top of the supporting plate 13, and a plurality of T-shaped blocks 15 are fixedly connected to the bottom of the trolley plate 3, and the T-shaped blocks 15 are slidably connected to the T-shaped limit grooves 12. The bottom of the supporting plate 13 adopts a plurality of T-shaped blocks 15 to cooperate with the T-shaped limit grooves 12 because the T-shape can prevent the slider from deforming and shifting. Increasing the number of T-shaped blocks 15 can significantly improve the stability of the connection between the trolley plate 3 and the supporting plate 13, and the T-shaped limit grooves 12 are perpendicular to the rotation direction of the rotating gear ring 9. Since there is no force parallel to the T-shaped limit grooves 12, the trolley plate 3 does not need to be limited, and the trolley plate 3 can be firmly connected to the supporting plate 13.

[0025] Furthermore, an electromagnetic mounting plate 10 is installed on the top of the cart plate 3, and a number of electromagnets 11 are installed on the top of the electromagnetic mounting plate 10. The electromagnets 11 are distributed in a linear array. A battery box 5 is installed on the top of the cart plate 3, and the battery box 5 is electrically connected to the electromagnet 11. Installing the battery box 5 on the cart plate 3 can greatly increase the flexibility of the tooling and avoid the problem of the power cord getting tangled during rotation under the traditional power cord power supply method.

[0026] Furthermore, a trolley handle 4 is provided on the top of the trolley plate 3, and the trolley handle 4 and the trolley plate 3 are in transitional fit. The trolley handle 4 and the trolley plate 3 are set as a transitional fit so that the trolley handle 4 can be removed before the trolley plate 3 rotates, thereby preventing the trolley handle 4 from interfering with the maintenance personnel's repair work on the centrifuge during the rotation process. Universal wheels 14 are installed at the four corners of the bottom of the trolley plate 3. The addition of the universal wheels 14 greatly improves the convenience of the maintenance personnel in transferring the centrifuge they need to repair, which meets the actual production needs.

[0027] Furthermore, the cross-section of the sliding groove 16 is in an inverted T-shape, the horizontal section of the sliding groove 16 passes through the guide ring 1, the cross-section of the rotating gear ring 9 is also in an inverted T-shape, and the supporting plate 13 is fixedly connected to the horizontal section of the rotating gear ring 9. The horizontal section of the sliding groove 16 passes through the guide ring 1 so that the supporting plate 13 fixed to the horizontal section of the rotating gear ring 9 can rotate 360° without dead angles, which is convenient for maintenance personnel to adjust and use.

[0028] Furthermore, an operating platform 17 is fixedly connected to the top of the base 7. The operating platform 17 will provide maintenance personnel with a platform for maintenance operations and a space for placing relevant maintenance tools during the use of the tooling. The top of the supporting plate 13 is horizontal, and the supporting plate 13 and the vertical surface of the rotating gear ring 9 are perpendicular to each other. The vertical surfaces of the supporting plate 13 and the rotating gear ring 9 are perpendicular to each other, which can ensure that no matter to which angle the supporting plate 13 is rotated, the bottom of the supporting plate 13 will point to the center of the rotating gear ring 9, which is convenient for maintenance personnel to perform maintenance.

[0029] In summary:

[0030] When the centrifuge needs to be repaired and maintained, the centrifuge to be repaired is placed on the electromagnet 11 on the carrying plate 13, and the entire cart is pushed onto the carrying plate 13 through the operating platform 17, and the T-shaped block 15 is ensured to slide into the T-shaped limit groove 12. The power in the battery box 15 is turned on, and the electromagnet 11 tightly adsorbs the metal centrifuge on the cart plate 3. The cart handle 4 is pulled up vertically, and the drive motor 6 on one side is started to drive the drive gear 2, thereby causing the rotating gear ring 9 to rotate forward. When it rotates to the required angle, the drive motor 6 is turned off, and maintenance can begin. When further reversal is required, the drive motor 6 on the other side can be turned on to drive the entire rotating gear ring 9 to reverse. This tooling not only solves the problem in the prior art that the centrifuge can only be placed on the ground and cannot be fixed, but more importantly, it also solves the problem that in the traditional maintenance method, maintenance workers need to bend over for a long time and put their bodies into the centrifuge for maintenance, which greatly damages the health of the maintenance workers. In addition, by installing a battery box on the cart plate 3, the problem of traditional power cord being entangled when used in this tooling is prevented, thereby increasing the practicality and safety of the tooling.
