Description

Technical Field

[0001] This utility model relates to the field of bucket wheel maintenance technology, specifically to a bucket wheel machine maintenance platform. Background Technology

[0002] Bucket wheel excavators, also known as bucket wheel stacker-reclaimers, are core equipment for efficient loading and unloading of large bulk materials in storage yards, widely used in ports, mines, power plants, and other industries. Their core structure includes a cantilever arm capable of tilting and swinging horizontally, a rotating bucket wheel at the front, a frame, and a running mechanism. They collect material through the rotating bucket wheel, and the bidirectional operation of the conveyor arm enables both stacking and reclaiming operations, featuring continuous operation, high efficiency, and strong adaptability. For example, in thermal power plants, bucket wheel excavators can accurately classify and store different types of coal and provide fuel to boilers through a conveying system; a single unit can handle tens of thousands of tons per day. The bucket wheel excavator maintenance platform is a crucial facility for ensuring the safe operation of the equipment. Taking a utility model patent as an example, it uses an electric guide rail to drive the platform to tilt, utilizing the lever principle to push the bucket wheel excavator to the center of the platform, avoiding the high risks and costs of traditional hoisting. The platform is equipped with jacks to support the platform, and the base adopts an X-shaped cross-reinforcement structure to ensure load-bearing stability. Some platforms also integrate casters for easy movement to different work points. This design significantly reduces the difficulty of maintenance, improves maintenance efficiency, and provides a reliable guarantee for the continuous operation of bucket wheel excavators.

[0003] CN205713020U discloses a bucket wheel excavator maintenance platform, including a base frame, a workbench mounted on the base frame, a moving track mounted on the workbench, a hinge seat slidably mounted on the moving track, and a rotating arm hinged to the hinge seat. The rotating arm houses a maintenance lift. The bottom of the base frame has multiple casters and multiple liftable legs. When the liftable legs are raised, they support the platform; when the liftable legs are lowered, the platform can be moved via the casters. When stored, the rotating arm can be rotated downwards along the hinge seat, making it parallel to the workbench, thus reducing the platform's height and storage space, facilitating storage.

[0004] The aforementioned bucket wheel excavator maintenance platform's rotating arm relies solely on limit pads and lacks a rigid locking mechanism; it is prone to swaying during personnel lifting and lowering, and poses a risk of overturning in strong winds. Utility Model Content

[0020] The rotary self-locking assembly 2 also includes a support frame 21, which is symmetrically and fixedly connected to the inner compartment of the main support 12. The rotary self-locking assembly 2 also includes a main rotating shaft 23, which is rotatably connected to the middle of the two sets of support frames 21. The rotary self-locking assembly 2 also includes a forward and reverse motor 22, which is fixedly installed on the outside of a set of support frames 21; The rotary self-locking assembly 2 also includes a worm gear 231, which is fixedly connected to the outside of the main shaft 23; The rotary self-locking assembly 2 also includes a secondary rotating shaft 24, which is rotatably connected to the main support 12, and the secondary rotating shaft 24 is fixedly connected to the secondary rod 25; The rotary self-locking assembly 2 also includes a worm gear 241, which is fixedly connected to the outside of the secondary rotating shaft 24. The worm gear 241 is in contact with the worm 231 and is meshed and rotated. When climbing ladder 251 is needed for maintenance work, the forward and reverse motor 22 can be started to drive the main shaft 23 and worm gear 231 to rotate inside the two sets of support frames 21. At this time, under the meshing action of worm gear 231 and worm wheel 241, the auxiliary shaft 24 located inside the worm wheel 241 can drive the auxiliary rod 25 and ladder 251 to rotate 90 degrees, thereby completing the work of erecting ladder 251 on the top of support platform 11.

The worm gear 231 and worm wheel 241 adopted in this design The meshing rotation can produce a self-locking effect, thereby preventing the ladder 251 from tilting or swaying. After the auxiliary rod 25 drives the ladder 251 to complete the erection work on the top of the support platform 11, the cylinder 31 can be activated to make the extension end of the cylinder 31 drive the wedge block 32 to move upward, thereby making the wedge block 32 insert into the wedge groove 34. Through this design, in conjunction with the worm gear 231 and the worm wheel 241, the ladder 251 can be double locked, thereby greatly improving the climbing safety of the ladder 251.
