Description

Technical Field

[0001] This utility model belongs to the technical field of port bulk cargo loading and unloading equipment, specifically, it relates to a hopper lifting and transfer vehicle. Background Technology

[0002] Currently, port hoppers (such as bulk cargo hoppers and overhead hoppers) are mainly transported using large forklifts or towed by rollers installed at the bottom during the transfer process. However, both of these methods have certain drawbacks in terms of efficiency and safety.

[0003] I. Disadvantages of using large forklifts for transportation:

[0004] 1. Efficiency issues and limited operating space: When forklifts operate in narrow areas of the port (such as between ships and storage yards), they require a large turning radius, which affects the overall transfer efficiency.

[0005] 2. Safety issues and overloading risks: Port hoppers are typically heavy, and overloading a forklift could lead to tipping accidents. Blind spot accidents: Forklift visibility is limited, increasing the risk of collisions with personnel and equipment in the complex port environment. Poor cargo stability: Hoppers may shift during forklift handling due to vibration or improper operation, causing cargo to slip.

[0006] II. Disadvantages of adding wheels to the bottom for dragging:

[0007] 1. Efficiency issues and poor ground adaptability: When the rollers are dragged on uneven or slippery surfaces in the port (such as the dock front), they may get stuck or slip, affecting transfer efficiency. Inaccurate positioning: The dragging method makes it difficult to precisely control the stopping position of the hopper, which may affect subsequent loading and unloading processes.

[0008] 2. Safety issues: Roller wear / malfunction: Rollers are prone to wear after prolonged use, which may cause the hopper to tilt or become uncontrollable. Uneven traction risk: Insufficient power or improper operation of the traction equipment (such as a trailer) may cause the hopper to tip over. Lack of securing measures: If the hopper is not effectively locked during towing, it may slip due to inertia, causing an accident.

[0009] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0010] Therefore, in order to solve the above problems, this utility model provides a funnel lifting and transfer vehicle. Utility Model Content

[0016] Furthermore, the hydraulic cylinder assembly includes a hydraulic cylinder barrel, which is fixedly connected to the lower support seat via a hydraulic cylinder pin. A hydraulic cylinder piston is movably connected to the hydraulic cylinder barrel, and one end of the hydraulic cylinder piston is connected to the movable frame assembly.

[0017] Furthermore, the movable frame assembly includes a lower connecting beam for the movable frame, with a movable frame inclined support A and a movable frame inclined support B connected to the top of the lower connecting beam. The movable frame inclined support A and the movable frame inclined support B are arranged crosswise.
