[0001] The utility model relates to the technical field of bucket wheel locking for stackers and reclaimers, in particular to a bucket wheel locking device for stackers and reclaimers. Background Art
[0002] Bucket wheel stacker reclaimer is a large-scale bulk material loading and unloading equipment with high efficiency and continuous operation. It is mainly used in coal and ore storage yards in industries such as power, metallurgy, coal, building materials and chemical industry. Bucket wheel stacker reclaimer is mainly composed of bucket wheel mechanism, cantilever belt conveyor, boom, balance beam, slewing platform, door seat, tail car, slewing mechanism, pitching mechanism and walking mechanism. The bucket wheel mechanism is installed at the front end of the boom to dig materials.
[0003] The locking effect of the existing stacker-reclaimer bucket wheel locking device may be affected after long-term use or in harsh environments, causing the bucket wheel to loosen or fall off, affecting the normal operation of the stacker-reclaimer. In addition, the locking device cannot be adaptively locked, resulting in low locking efficiency and certain safety hazards. Utility Model Content

Then, as the two are close to each other, the locking auxiliary clamp will squeeze the connecting tube, and the expansion assembly will start to work. During the movement of the connecting tube, the squeezing plate is driven by the push rod to expand outward to adapt to the gap between the reinforcement blocks. The gaps between the multiple reinforcement blocks are filled with the squeezing plate, so that the extension tube and the bucket wheel are tightly fitted. The design of the expansion assembly and the reinforcement block enhances the stability and durability of the locking device, improves the efficiency and safety of the locking operation, and has a good adaptive locking effect.

By placing the disc-type locking disc 1 and the locking auxiliary clamp 2 on the base 6, and then fixing the top cover 5 and the base 6 by bolts, the locking seat 3 can share a part of the radial load at the connection between the bucket wheel shaft end and the output end of the reducer, and isolate the harsh external environment, thereby effectively reducing the locking wear.
[0025] The adaptive locking assembly includes an inner rod 7, which is fixedly connected to the disc-type locking disk 1. A connecting tube 8 is sleeved on the disc-type locking disk 1, and a spring 9 is sleeved on the inner rod 7 and located between the disc-type locking disk 1 and the connecting tube 8.
