Description

Technical Field

[0001] This utility model relates to the field of bridge grab cranes, and in particular to a unloading system for viscous materials. Background Technology

[0002] In existing technology, a bridge grab crane uses its grab bucket to grab bulk materials from the ship's hold and then dumps them into a hopper in the middle of the crane, from where they flow into the opening of a vibrating feeder at the bottom of the hopper. Powered by a vibrating motor at the tail of the vibrating feeder, the feeder opening pushes the bulk material into a chute. The bulk material then flows through the chute to a belt conveyor on the ground, and is subsequently transported to the stockyard by the belt conveyor.

[0003] In particular, for bridge grab cranes unloading bauxite, bauxite has a high water content, strong viscosity, and poor fluidity, making it easy to stick to the hopper and vibrating feeder, thus clogging the unloading channel and causing strong vibrations to the whole machine.

[0004] Figure 1 This is a schematic diagram of the unloading system of a conventional bridge grab crane. Figure 2 This is a schematic diagram showing the installation of the feeder in the unloading system of a conventional bridge grab crane. (For example...) Figure 1 and Figure 2 As shown, a suspended vibrating feeder 20 is installed at the lower part of the hopper 10. A buffer pad 40 is provided between the feeder 20 and the hanger 30. When unloading bulk materials such as iron ore or coal, the bulk material is unloaded from the grab bucket 50 into the hopper 10, and then vibrated and conveyed by the feeder 20 to the chute 60, reaching the ground conveyor belt. During normal operation, the feeder 20 needs to maintain a certain gap with the hopper 10, and the thrust generated by the motor pushes the bulk material in the feeder 20 into the chute 60.

[0005] When the bulk material is a free-flowing material such as iron ore or coal, the conveying process is very smooth. However, if the bulk material is a highly viscous material such as bauxite, it easily adheres to the wall of the hopper 10, clogging the discharge port. The accumulated bauxite slowly flows into the gap between the hopper 10 and the feeder 20, accumulating more and more. The feeder body, carrying material, impacts the hopper 10, causing the gap between the hopper 10 and the feeder 20 to become smaller and smaller. When the gap disappears, part of the feeder's thrust is transferred to the hopper, reducing the thrust on the bulk material.

[0006] Because the funnel 10 is rigidly connected to the frame structure, it is susceptible to resonance under high-frequency thrust, which can damage the welds of the steel structure and electrical components. Bauxite has poor flowability; with the same funnel discharge flow rate and feeder, its production capacity can only reach 50%-70% of that of bulk materials with better flowability and the same specific gravity.

[0007] In view of this, the inventor of this utility model has designed a discharge system for viscous materials in order to overcome the above-mentioned technical problems. Utility Model Content

[0050] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0051] like Figure 3 and Figure 4As shown, this utility model discloses a unloading system for viscous materials, including: a feeder 100, a feeder base 200, a first buffer structure 300, a structural support member 400, a door frame support portion 500, and a second buffer structure 600. The feeder 100 is connected to the feeder base 200 via the first buffer structure 300, and the feeder 100 is located above the feeder base 200. The structural support member 400 is fixed to the door frame support portion 500. The feeder base 200 is connected to the structural support member 400 via the second buffer structure 600, and the feeder base 200 is located above the structural support member 400. The feeder 100 forms a double-layer buffer structure through the first buffer structure 300 and the second buffer structure 600 to absorb vibration and impact received by the feeder 100.

[0052] The unloading system for viscous materials further includes a hopper 700, a grab bucket 710, and a chute 720. The hopper 700 is connected to and located above the feeder 100. The grab bucket 710 is installed above the hopper 700, and the outlet of the feeder 100 is connected to the chute 720 to push the bulk material into the chute 720.

[0053] Preferably, the first buffer structure 300 includes a plurality of first buffer pads 310, which are respectively installed between the feet of the feeder 100 and the feeder base 200.

[0054] For example, such as Figure 4 As shown, in this embodiment, the first buffer structure 300 includes eight first buffer pads 310. The feeder 100 has four feet, and two first buffer pads 310 are respectively installed between each foot of the feeder 100 and the feeder base 200.

[0055] In this embodiment, the first buffer pad 310 is preferably a rubber buffer pad.

[0056] More preferably, the second buffer structure 600 includes a plurality of second buffer pads 610, which are respectively installed between the respective feet of the feeder base 200 and the structural support member 400.

[0057] For example, in this embodiment, the second buffer structure 600 includes twelve second buffer pads 610, the feeder base 200 has four feet, and three second buffer pads 610 are respectively installed between the feet of each feeder base 200 and the structural support member 400.

[0058] In this embodiment, the second buffer pad 610 is preferably a spring buffer pad.

[0059] like Figure 4As shown, in this embodiment, the feeder base 200 may preferably include at least two strip-shaped first connecting plates 210, which are respectively located on both sides of the feeder 100. Similarly, the structural support member 400 may preferably include at least two strip-shaped second connecting plates 410, which are respectively located on both sides of the feeder 100, and the second connecting plates 410 and the first connecting plates 210 are vertically corresponding.

Other quantities and arrangements are also applicable, as long as they can absorb vibration. They are all within the protection scope of this application and will not be elaborated here.

[0061] According to the above structural description, in this embodiment, the four corners of the vibratory feeder base 200 are fixed to the structural support member 400 by multiple spring buffer pads (i.e., second buffer pads 610), and then fixed to the door frame support part 500. Multiple rubber buffer pads (i.e., first buffer pads 310) are also provided between the feeder base 200 and the upper feeder 100. The double-layer buffer pads on the feeder base 200 can completely absorb the force generated when the motor is working, thereby ensuring that the motor will not cause resonance of the entire machine during full-frequency operation.

[0062] The vibrating feeder 100 adopts an eccentric block vibration method, with the motor mounted on the feeder base 200. The two feeder bases 200 with sufficient strength are rigidly connected in the middle. A double-layer buffer pad is set between the feeder base 200 and the structural support 400, which can fully absorb the impact caused by motor operation and unloading, and avoid the whole machine resonance phenomenon that may be caused by the vibrating feeder at a certain operating frequency during operation.

[0063] In summary, this utility model provides a discharge system for viscous materials that employs eccentric block vibration. The motor is mounted on the base, and a double-layer buffer pad is installed between the feeder base and the gantry support, effectively absorbing the impact caused by motor operation and discharge. This discharge system reduces the likelihood of blockage by viscous materials, eliminates strong vibrations throughout the machine, improves the overall discharge efficiency of the crane, and reduces maintenance costs.
