Description

Technical Field

[0001] This utility model relates to the field of flotation equipment technology, and in particular to a quick disassembly and maintenance structure for a direct-drive flotation machine. Background Technology

[0002] Flotation machines are key equipment widely used in industries such as mineral processing and wastewater treatment. Their operating status directly affects production efficiency and product quality. With technological development, direct-drive flotation machines are gradually replacing traditional belt-driven flotation machines due to their advantages such as high transmission efficiency and low energy consumption.

[0003] However, the motor and flotation mechanism of existing direct-drive flotation machines are usually fixedly connected. When the equipment needs to be repaired and maintained, a large number of connecting parts need to be disassembled, and the heavy direct-drive motor needs to be moved using hoisting equipment. This is not only complicated and time-consuming, but also poses safety hazards, which seriously affects the maintenance efficiency and production continuity of the equipment.

[0004] Therefore, how to design a structure that can quickly separate and connect the direct drive motor and the flotation mechanism has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a quick disassembly and maintenance structure for a direct-drive flotation machine, which solves the problems of difficult disassembly and low efficiency in the maintenance process of existing direct-drive flotation machines.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick disassembly and maintenance structure for a direct-drive flotation machine, comprising a direct-drive motor, a flotation mechanism, a moving mechanism, and a temporary placement mechanism. The direct-drive motor is bolted to the flotation mechanism via a coupling. The moving mechanism includes a support and a movable platform mounted on the support. The bottom of the support is hollow to accommodate the flotation mechanism. The movable platform is fixedly connected to the direct-drive motor. The direct drive motor moves away from the flotation mechanism along with the movable platform and is placed in the temporary placement mechanism; The direct drive motor moves closer to the flotation mechanism along with the movable platform, and is connected to the flotation mechanism via the coupling.

[0007] As a preferred embodiment of this utility model, the temporary placement mechanism has the same structure as the support and is disposed on one side of the support to form a second support.

[0008] Furthermore, the movable platform is bolted to the support, and the movable platform rotates horizontally around a bolt near the second support as a rotation point, and rotates to the second support, thereby enabling the direct drive motor to move away from the flotation mechanism.

[0009] As another preferred embodiment of this utility model, the second bracket is retractable and retractable, and the bracket is composed of several hollow steel pipes, with the second bracket retracting and retracting into the hollow steel pipes.

[0010] As another preferred embodiment of this utility model, the temporary placement mechanism is "⊥" shaped and fixedly installed on one side of the bracket, including a support body with a rounded top, for adapting to the direct drive motor.

[0011] Furthermore, the movable platform is connected to the bracket near the support body via a hinge, and to the side away from the support body via bolts. The movable platform is flipped away from the flotation mechanism via the hinge and placed on the support body.

[0012] Further optimization involves adding reinforcing ribs at the connection between the support body and the bottom of the temporary placement mechanism to improve support strength and stability.

[0013] The working process of this utility model is as follows: When the flotation machine needs to be repaired, firstly, the connecting bolts of the coupling between the direct drive motor and the flotation mechanism are removed. Then, by operating the moving mechanism, the movable platform is moved away from the flotation mechanism until the direct drive motor is placed stably on the temporary placement mechanism. At this time, the flotation mechanism is fully exposed, which facilitates comprehensive repair. After the repair is completed, the direct drive motor is moved back to its original position from the temporary placement mechanism by the moving mechanism. Then, the direct drive motor and the flotation mechanism are reconnected by the coupling bolts to complete the assembly. Beneficial effects

[0014] 1. By combining a mobile platform and a temporary placement mechanism, the direct drive motor and flotation mechanism can be quickly separated and connected, greatly shortening the maintenance preparation time and significantly improving maintenance efficiency.

[0015] 2. No large hoisting equipment is required. The direct drive motor can be moved by simple translation or flipping operations, which reduces the difficulty of operation and safety risks, making operation safe and convenient.

[0016] 3. The hollow design at the bottom of the support not only ensures the normal installation of the flotation mechanism, but also provides ample space for its maintenance; the multiple design options for the temporary placement mechanism can adapt to different usage scenarios, and the structural design is reasonable.

[0017] 4. The stability of the equipment during operation and movement is ensured by means of bolted connections and hinge connections. The addition of reinforcing ribs further improves the load-bearing capacity of the temporary placement mechanism, resulting in good stability.

[0018] 5. The retractable and foldable second stand design allows the device to be stored inside the stand when not in use, reducing the space occupied by the equipment and saving space. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0022] like Figures 1-5 As shown, a quick disassembly and maintenance structure for a direct-drive flotation machine includes a direct-drive motor 1, a flotation mechanism 2, a moving mechanism 3, and a temporary placement mechanism 4. The direct-drive motor 1 and the flotation mechanism 2 are bolted together by a coupling 5. The moving mechanism 3 includes a bracket 31 and a movable platform 32 mounted on the bracket. The bottom of the bracket 31 is hollow to accommodate the flotation mechanism 2. The movable platform 32 is fixedly connected to the direct-drive motor 1. The direct drive motor 1 moves away from the flotation mechanism 2 along with the movable platform 32 and is placed on the temporary placement mechanism 4; The direct drive motor 1 moves close to the flotation mechanism 2 along with the movable platform 32, and is connected to the flotation mechanism 2 via the coupling 5.

[0023] When the flotation machine needs maintenance, first remove the connecting bolts of the coupling 5 between the direct drive motor 1 and the flotation mechanism 2. Then, by operating the moving mechanism 3, the movable platform 32 is moved away from the flotation mechanism 2 until the direct drive motor 1 is placed stably on the temporary placement mechanism 4. At this time, the flotation mechanism 2 is fully exposed, which facilitates comprehensive maintenance. After the maintenance is completed, the direct drive motor 1 is moved back to its original position from the temporary placement mechanism 4 by the moving mechanism 3. Then, the direct drive motor 1 and the flotation mechanism 2 are reconnected by the bolts of the coupling 5 to complete the assembly.

[0024] like Figures 1-3 As shown, in this embodiment, the temporary placement mechanism 4 has the same structure as the bracket 31 and is set on one side of the bracket 31 to form a second bracket 41.

[0025] In this embodiment, the movable platform 32 is bolted to the support 31. The movable platform 32 rotates horizontally with a bolt 6 near the second support 41 as the rotation point, and rotates to the second support 41, so that the direct drive motor 1 moves away from the flotation mechanism 2.

[0026] In this embodiment, the second bracket 41 is retractable and retractable, such as... Figures 1-4 As shown, the support 31 is composed of a hollow steel pipe 310, and the second support 41 is telescopically stored inside the hollow steel pipe 310. Example 2

[0027] The difference from Example 1 is that: like Figures 4-5 As shown, the temporary placement mechanism 4 is shaped like a "⊥" and is fixedly installed on one side of the bracket 31, including a support body 42 with a rounded top, which is used to adapt to the direct drive motor 1.

[0028] In this embodiment, the movable platform 32 is connected to the support 31 on the side near the support body 42 by a hinge 7, and on the side away from the support body 42 by a bolt. The movable platform 32 is flipped away from the flotation mechanism 2 by the hinge 7 and placed on the support body 42.

[0029] In this embodiment, a reinforcing rib 43 is provided at the bottom connection between the support body 42 and the temporary placement mechanism 4 to improve the support strength and stability.

[0030] The above description is only used to more clearly describe the present utility model and should not be regarded as limiting the scope of protection covered by the present utility model. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present utility model.
