Description

Technical Field

[0001] The utility model relates to the technical field of scrap steel transport vehicles, in particular to a scrap steel transfer vehicle which is convenient for unloading. Background Art

[0002] At present, the molten steel produced by the converter or electric furnace of a steel plant generally needs to be smelted by adding scrap steel raw materials into the furnace first and then adding molten iron for smelting. Scrap steel refers to the waste steel that is eliminated or damaged in production and life projects and is recycled. It generally includes steel ingots, continuous castings and bars, steel pipe processing production waste and purchased scrap iron blocks. The weight, size and shape of these scrap steel raw materials are not consistent, and a transport cart is needed to transfer these scrap steels over short distances during production.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN220180868U discloses a transport vehicle for scrap steel transfer, including a vehicle body and a vehicle leg connected to the bottom of the vehicle body, a universal wheel connected under the vehicle leg, and a vehicle body including a horizontal first bottom plate, a side plate connected to the edge of the top surface of the first bottom plate, and a flap hinged on the side of the first bottom plate. When the flap is flipped to a first state, i.e., vertical, the flap and the side plate form a storage space with an opening at the top. When the flap is flipped to a second state, the side away from the hinged end contacts the ground, and the flap is in a tilted downward posture. The top surface of the first bottom plate is also provided with an inclined top surface, which is tilted downward from the side plate to the flap. After the transport vehicle in the utility model transfers the scrap steel, the scrap steel can be quickly unloaded by using its inclined slope and flap, which solves the problem of inconvenience in unloading after the previous transport vehicle transports the scrap steel, greatly improves the operation efficiency, has a simple structure, and is ingeniously designed.

[0004] In order to prevent scrap steel from falling from the bucket during the transfer process, the scrap steel transfer truck generally has a rectangular frame structure with an openable baffle at the rear end of the bucket. This structure requires manual unlocking of the baffle during unloading, which is very inconvenient. After the baffle is unlocked, the scrap steel above the bucket may fall and injure the staff. At the same time, due to the weight of the scrap steel, the friction between the scrap steel and the bucket is relatively large. During the unloading process, the scrap steel may not slide out of the bucket, affecting the unloading efficiency. Utility Model Content
