Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment technology, specifically to a mobile dust suppression device for loading and unloading dry bulk cargo. Background Technology

[0002] Bulk cargo refers to bulk cargo loaded and unloaded at the dock. These goods typically include ores, coal, grains, cement, etc. Due to their shape, size, weight, or other characteristics, they are not suitable or can not be loaded into standard containers. Instead, they are directly loaded into the cargo hold or deck of the ship for transport. The storage method of bulk cargo at the dock is generally quite special. Loading and unloading are required using loaders or other specialized equipment, and they usually do not need to be stored in a fixed location. Instead, they are directly piled up on the dock waiting for shipment.

[0003] The traditional process for unloading cargo from a bulk cargo terminal yard involves manually controlling a loader bucket to pour the scooped material into dump trucks, which then transport the material horizontally to disperse it. This loading process is an open loading operation mode, which usually lacks relevant dust suppression measures. The dispersion of material dust is particularly noticeable to the eye, which is detrimental to yard operations and the surrounding environment, and will also bring serious negative impacts and losses to the company.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] See Figures 1-3 As shown, this utility model provides a mobile dust suppression device for loading and unloading dry bulk cargo, including a rectangular top frame 1, a canopy frame 2, and four support legs 3. The four support legs 3 are fixedly connected to the four corners of the bottom surface of the rectangular top frame 1. The lower ends of the two front support legs 3 are each equipped with a walking mechanism. A crossbeam 301 is fixedly connected above the two left and right support legs 3. A traction beam 303 is fixedly connected below the two rear support legs 3. The two front support legs 3 cooperate with the rectangular top frame 1 to form a loading channel for a loader, and the lower parts of the left and right crossbeams 301 cooperate with the support legs 3 to form a dump truck entry and exit channel. Dustproof structures are provided around the bottom of both the canopy frame 2 and the rectangular top frame 1.

[0022] As an optional implementation, the walking mechanism includes wheel axles 401 fixedly connected to the lower ends of the two front outriggers 3. Each wheel axle 401 is rotatably connected to a movable wheel 4. Wheel axle reinforcement members 402 are fixedly connected between each wheel axle 401 and the outrigger 3. The lower sides of the two movable wheels 4 are flush with the lower ends of the two rear outriggers 3. Large-volume equipment can be easily turned and moved using a forklift, meeting the needs of various site operations. The wheel axle reinforcement members 402 are triangular, which improves the support strength of the wheel axles 401.

[0023] Reference Figure 3 As shown, a diagonal bracing rod 302 is fixedly connected between the upper surface of the crossbeam 301 and the rectangular top frame 1. A triangular stabilizing rod 304 is fixedly connected between the upper surface of the traction beam 303 and the rectangular top frame 1. A sleeve hole 305 for connecting with a forklift is opened in the middle of the bottom surface of the traction beam 303. Diagonal bracing frames 306 are fixedly connected between the bottom ends of the two crossbeams 301 and the support legs 3. Diagonal bracing frames 307 are fixedly connected between the upper ends of the two front support legs 3 and the rectangular top frame 1. This makes the connection between the rectangular top frame 1 and the four support legs 3 more stable and improves the overall structural strength of the dust suppression shed. The traction beam 303 is no less than 2 meters above the ground. A matching fork disc can be inserted into the fork arm of the forklift. The protruding rod on the fork disc is inserted into the sleeve hole 305 from bottom to top. At this time, the dust suppression shed can be moved by the forklift.

[0024] As an optional implementation, the canopy frame 2 includes herringbone end plates 201 fixedly connected to both ends of the upper surface of the rectangular top frame 1. Several herringbone support plates 202 are evenly distributed between the two herringbone end plates 201, and the herringbone support plates 202 are all fixedly connected to the upper surface of the rectangular top frame 1. Several connecting rods 203 are fixedly connected between the two herringbone end plates 201, and the several connecting rods 203 simultaneously connect the several herringbone support plates 202 through them. A triangular stabilizing rod 204 is fixedly connected between the bottom of the two herringbone end plates 201 and the rectangular top frame 1. This can achieve a simple, lightweight, stable, and reliable structure. The canopy frame support structure of the loading shed steel structure bracket is designed in an inverted V shape to prevent dust accumulation.

[0025] Reference Figure 2As shown, the dustproof structure includes a dustproof top net 6 and three dustproof vertical nets 5. The dustproof top net 6 completely covers the area between the two herringbone end plates 201 and the area below the herringbone end plates 201. The three dustproof vertical nets 5 are located above the traction beam 303 and the two crossbeams 301, respectively, and completely cover the space between the rectangular top frame 1 and the traction beam 303 and the two crossbeams 301. The dustproof top net 6 and the three dustproof vertical nets 5 are all tied and fixed to the roof frame 2 and the outriggers 3 with cable ties. The dustproof top net 6 and the three dustproof vertical nets 5 are both double-layered designs, which can significantly reduce dust dispersion in all directions during loading operations. The equipment materials are windproof and breathable, avoiding the risk of overturning in strong winds.

[0026] Specifically, the dustproof structure also includes three dust suppression curtains 7. One dust suppression curtain 7 is fixedly connected to the lower front side of the rectangular top frame 1, and the other two dust suppression curtains 7 are fixedly connected to the lower side of the two crossbeams 301 respectively. The dust suppression curtain 7 is composed of several conveyor belt rubber sheets arranged in sequence, and the lower center of the dust suppression curtain 7 is concave. When dump trucks and loaders enter the dust suppression canopy, the dust suppression curtain 7 can fit the height and shape of the vehicle body, effectively preventing a large amount of dust from overflowing.

[0027] Working principle:

[0028] In use, a forklift is used to insert a docking tool into the sleeve hole 305 in the middle of the bottom surface of the traction beam 303. Then, the forklift arm is raised until the two rear outriggers 3 are off the ground. As the forklift moves, the two moving wheels 4 are used to move the suppression device. After it moves to the loading position, the two rear outriggers 3 are controlled to land, allowing the dump truck to dump into the dust suppression shed from under the crossbeam 301. Meanwhile, the loader dumps the goods into the dump truck bed inside the dust suppression shed from between the two front outriggers 3. At this time, the dust is covered in the dust suppression shed by the dust suppression curtain 7, the dustproof top net 6, and the dustproof vertical net 5, which plays a role in suppressing the drifting dust.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
