Description

Technical Field

[0001] The utility model relates to the technical field of bucket fixing of port stacker reclaimers, and specifically discloses a bucket fixing device for port stacker reclaimers. Background Art

[0002] A bucket wheel stacker reclaimer is an efficient loading and unloading machine for continuous conveying that can both stack and reclaim materials in large dry bulk yards. It consists of a belt conveyor arm that can pitch and swing horizontally, a bucket wheel at its front end, a frame, and a running mechanism, and the belt can run in both directions. When reclaiming materials, the bucket wheel reclaims materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown onto the yard through the conveyor arm. It is widely used in ports, power plants, steel mills, cement plants and other places that require large-scale stacking and reclaiming of bulk materials.

[0003] During the maintenance of the bucket wheel of a port stacker reclaimer, maintenance personnel must fix the bucket wheel to prevent the bucket wheel from suddenly rotating under the action of strong winds and external forces, causing harm to the maintenance personnel during the operation.

[0004] At present, due to the lack of fixing tools for the bucket wheel, welding is usually used to fix the rotation of the bucket wheel. When maintaining the next bucket wheel after maintaining one bucket wheel, the bucket wheel also needs to be hoisted and pulled, and at this time, the welded part must be cut with gas welding. Repeated welding and gas cutting easily cause damage to the bucket wheel, reduce its service life, and greatly increase the maintenance labor intensity. Summary of the Utility Model

[0005] Aiming at the above deficiencies of the prior art, the utility model provides a bucket fixing device for a port stacker reclaimer to solve the problems that repeated welding and gas cutting easily cause damage to the bucket wheel, reduce its service life, and greatly increase the maintenance labor intensity.

When in use, fix the chain block, connect the bucket connection fixture to the bucket wheel, tighten the chain block to fix the bucket wheel, and then fix the anti-detachment fixture; welding and gas cutting operations are avoided, damage to the bucket wheel is avoided, the service life is prolonged, and the labor intensity is reduced. Through the setting of the anti-detachment fixture, when the connection between the bucket connection fixture and the bucket wheel accidentally detaches, it can prevent the bucket connection fixture from falling, reducing potential safety hazards.

[0008] Preferably, the bucket connection fixture includes a first concave-shaped plate; a first screw is threadedly provided on one side wall of the first concave-shaped plate; a U-shaped hook is fixedly provided on the first concave-shaped plate and is disposed on the opposite side of the first screw; one end of a flexible belt is detachably connected to the first concave-shaped plate. The first concave-shaped plate can be used to place at the edge of the bucket, and the first screw is used to clamp the bucket.
