Description

Technical Field

[0001] The utility model relates to the technical field of bulk material conveying and loading / unloading, and particularly relates to a cantilever type unloading truck. Background Art

[0002] In the field of bulk material loading, unloading and transportation, traditional unloading devices mostly adopt fixed or simple track type conveying structures. When applied to material transfer scenarios such as coal mines, ports, steel plants, and building materials, there are problems such as poor adaptability, large structural rigidity, and limited unloading range. Especially in working conditions that require multi-angle, long-distance or off-center batching, existing fixed unloading equipment often fails to meet the actual use requirements.

[0003] At present, the cantilever type unloading device is a conveying equipment with a certain flexible adjustment ability. Typical structural forms include directly setting a conveyor on a mobile trolley, and it can only adjust the inclination angle and cannot achieve rotation. Moreover, its cantilever is short. Another type is directly set on a slewing support, and a multi-directional unloading is achieved through a conveying mechanism connected to the slewing structure. Although such structures improve the batching range of the equipment to a certain extent, there are still the following deficiencies in actual applications: There is no effective buffer or stable tensioning structure between the slewing component and the suspended conveying section. When the load is large or the batching direction changes frequently, the stability of the connection part is insufficient, affecting the overall unloading accuracy and safety. For example, Chinese Patent Application No. 202310990905.7 discloses an intermediate support structure for a large-slope continuous conveyor in an open-pit mine. By slewing the intermediate support structure, the flexibility of unloading is improved; the pitching mechanism is installed at the lower part of the unloading arm, reducing the overall volume. The conveyor is directly set on the slewing support. Due to the lack of an effective buffer or stable tensioning structure, the operation is unstable. Once the angle changes, the position of the feed inlet also changes accordingly, affecting the feeding of the feeding equipment.

[0004] Chinese Patent Application No. 201510976986.0 discloses a cantilever type hydraulic lifting belt two-way conveyor, including a mobile support and a conveying mechanism. Rollers are installed at the lower end of the support, which can effectively extend the belt conveyor into the railway car body and can load and unload railway car bodies. When the inclination angle of the conveyor becomes larger, the conveyed materials are not easy to slip. This structural form is to directly set the conveyor on a mobile trolley, with a short cantilever and unable to achieve multi-angle adjustment. Therefore, how to provide a cantilever type unloading truck with a safe and reliable structure, capable of flexibly adjusting the unloading direction and conveying length, and having a strong load adaptability has become one of the key technical problems urgently to be solved in this field.
