Description

Technical Field

[0001] This utility model relates to the field of drum structure technology, specifically an adjustable electric single-girder crane drum. Background Technology

[0002] Adjustable electric single-girder crane drums mainly refer to the drum system on electric single-girder cranes. This system is used to wind and unwind wire ropes, thereby driving the crane's hook or other lifting devices to perform vertical lifting operations. The design of adjustable drums is usually to improve the flexibility and operational accuracy of the equipment.

[0003] When using traditional devices, if the drum is a one-piece design, the structure may not be able to be adjusted according to different needs, resulting in the inability to customize or expand according to requirements during use.

[0004] Secondly, the lack of a locking mechanism may cause components to loosen during use due to vibration or load changes, affecting the stability of the equipment.

[0005] Finally, without the cooperation of the drive disc and driven gear, the rotation of the drum may become unstable, such as uneven power transmission, resulting in unstable lifting and lowering movements. Summary of the Invention

[0015] This invention, by incorporating a locking assembly, utilizes the cooperation of mating and positioning components to fix the assembled components in a fixed position, preventing loosening or deformation during operation and ensuring the stability and safety of the drum. This is particularly important for high-load operations, effectively preventing unexpected malfunctions caused by structural loosening.

[0016] In this invention, by setting up a running mechanism, the interaction between the drive disc and the driven gear, through the cooperation of components such as the motor and drive disc, enables the drum to rotate more smoothly and precisely. Gear transmission effectively reduces slippage or errors that may occur with other transmission methods (such as belts or chains), resulting in more precise load lifting and lowering.

[0021] In this embodiment, the installation mechanism includes an installation rod 2 and a rolling bearing 3. During use, the installation rod 2 is first installed onto the main body 1. The limiting groove 11 on the installation rod 2 engages with the first limiting block 12 on the rolling bearing 3. During installation, the installation rod 2 passes through the rotating cylinder 4, causing the second limiting block 16 on the rotating cylinder 4 to slide against the limiting groove 11. Furthermore, after the installation rod 2 is installed, the roller 14 on the limiting plate 13 of the installation rod 2 directly slides against the sliding groove 15 on the main body 1. In addition, the connector 5 can be installed on the mounting rod 2. The second limiting block 16 on the connector 5 is connected with the limiting groove 11. Then, when installing the connector 5, the mating part 6 is rotated so that the screw 18 on the mating part 6 is connected with the threaded hole 17. At the same time, the locking part is pulled in advance so that the locking part can slide in the mating part 6 and compress the spring 8. After the connector 5 and the mounting rod 2 are installed, the positioning part 7 is released so that the positioning part 7 is connected with the positioning hole 19, so that the connection between the connector 5 and the mounting rod 2 is fixed.

[0023] Example 2: In summary, during use, the device is first assembled. The mounting rod 2 is then installed onto the main body 1. The limiting groove 11 on the mounting rod 2 engages with the first limiting block 12 on the rolling bearing 3. During installation, the mounting rod 2 passes through the rotating cylinder 4, causing the second limiting block 16 on the rotating cylinder 4 to slide with the limiting groove 11. Furthermore, after the mounting rod 2 is installed, the roller 14 on the limiting plate 13 of the mounting rod 2 directly slides with the sliding groove 15 on the main body 1. Additionally, the connecting piece 5 can be installed onto the mounting rod 2, with the second limiting block 16 on the connecting piece 5 engaging with the limiting groove 11. Subsequently, the connection is further assembled. When connecting part 5 is installed, simultaneously rotate mating part 6 so that the screw 18 on mating part 6 engages with the threaded hole 17. At the same time, pull the locking part in advance so that the locking part can slide in mating part 6 and compress the spring 8. After connecting part 5 and mounting rod 2 are installed, release positioning part 7 so that positioning part 7 engages with positioning hole 19, thus fixing the connection between connecting part 5 and mounting rod 2. In use, motor 9 installed on main body 1 starts to drive, and drive teeth 21 on drive disk 10 directly engage with driven teeth 20 on connecting part 5, so that mounting rod 2 can rotate. Rotary drum 4 installed on mounting rod 2 also rotates on main body 1.
