Description

Technical Field

[0001] The present invention relates to the technical field of port equipment, and particularly to a bulk cargo ship loading device for direct unloading and direct loading. Background Art

[0002] A ship loader is a special port machinery used in the ship loading operation of a bulk cargo terminal. Currently, the commonly used ship loaders basically use fixed belt conveyors for feeding and cannot accept direct unloading from trucks. The materials transported by trucks need to be unloaded to the yard first, and then taken to the fixed conveyor by a single-bucket reloader, a stacker-reclaimer, etc. to feed the ship loader for loading. Or the truck materials are unloaded to the fixed conveyor through a fixed truck unloading platform machine and a discharge hopper to feed the ship loader. In actual projects, some terminals do not have the conditions to set up a rear yard or install a fixed belt conveyor. For this reason, Chinese Patent No. 201910695893.9 discloses a mobile ship loader for truck unloading, which can accept direct truck unloading, but the truck needs to turn around before unloading, resulting in a large requirement for the terminal operation space, and is not conducive to the traffic organization of terminal vehicles and equipment. There is a traffic flow intersection, affecting safety and effectiveness. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a direct unloading and direct loading bulk cargo ship loading device with a simple and compact structure, rapid movement, safety and environmental protection, where the truck does not need to turn around for unloading, and has a small requirement for the terminal operation space, aiming at the defects existing in the prior art.

[0004] To solve the above technical problem, the present invention adopts the following technical solution: A direct unloading and direct loading bulk cargo ship loading device, including a walking platform, characterized in that: a telescopic ship loading mechanism and a vertical lifting mechanism are installed on the walking platform. The vertical lifting mechanism forms a vertical ring structure. At the bottom of the vertical lifting mechanism, there is a receiving area that can directly receive truck unloading. The vertical ring structure of the vertical lifting mechanism forms a passage for the truck to directly pass through. After the truck passes through this passage, the truck hopper is aligned with the receiving area for unloading; the telescopic ship loading mechanism is horizontally arranged on the walking platform and extends outward from the walking platform to above the ship to be loaded to form a structure for loading materials onto the ship; a material transfer passage is provided between the vertical lifting mechanism and the telescopic ship loading mechanism to form a structure for transferring materials from the vertical lifting mechanism to the telescopic ship loading mechanism.

[0005] Furthermore, the vertical lifting mechanism includes a vertical conveyor, a grille plate, and a discharge chute that can circulate along the vertical ring structure. The vertical conveyor is installed on the walking platform. The grille plate is arranged above the bottom of the vertical conveyor, and the car receiving hopper is formed by the grille plate and the lower part of the vertical conveyor. The discharge chute is arranged at the discharge opening above the vertical conveyor, and is docked with the telescopic ship loading mechanism to realize the conveyance of materials to the telescopic ship loading mechanism. After the materials are unloaded into the receiving hopper (i.e., the receiving area), they are lifted by the vertical conveyor along the feeding channel inside it. After being lifted to the top, they are then conveyed to the telescopic ship loading mechanism for ship loading.

[0006] Furthermore, the walking platform is of a gantry structure. The telescopic ship loading mechanism is installed on the upper part of the gantry. Walking wheels are arranged at the bottom of the gantry, and the walking wheels are made of rubber wheels or steel wheels. The entire device can be flexibly moved through the walking wheels, and can also be automatically moved by installing a power device. The specific implementation process is prior art and will not be elaborated here.

[0007] Furthermore, the telescopic ship loading mechanism includes a fixed boom, a telescopic boom, and a ship loading chute. The fixed boom is installed on the walking platform. The telescopic boom is installed inside the fixed boom to form a structure that can extend and retract along the length direction of the fixed boom. Conveyor belts are installed on both the fixed boom and the telescopic boom to convey the ship loading materials. The ship loading chute is connected to the end of the telescopic boom. After the telescopic boom extends, the ship loading chute is extended above the ship to be loaded.

[0008] Furthermore, the vertical conveyor is a chain bucket elevator, an en masse conveyor, or a corrugated sidewall conveyor. A vibrator for accelerating the falling of materials is installed on the grille plate to prevent sticking and blockage.

[0009] Furthermore, mobile car unloading platforms are arranged on the front and rear sides of the vertical lifting mechanism. A guiding channel for the car to reach the receiving area is formed through the mobile car unloading platforms, so that the car can drive onto the receiving area through the mobile car unloading platforms for unloading. The mobile car unloading platforms are fixedly connected to the walking platform.

[0010] Furthermore, the mobile car unloading platform is in the form of a ramp, with a higher middle part and lower front and rear ends. The slopes of the two side mobile car unloading platforms are 1:8 to 1:12. Walking tires are arranged at the bottom of the mobile car unloading platform to move along with the walking platform.

[0011] Furthermore, a sealing cover is arranged around the receiving area. The sealing cover is installed on the walking platform and forms a door frame shape along the receiving area so that the car can directly pass through. A dust removal device is installed on the sealing cover to absorb and remove the dust generated during the car unloading process, so that the dust during the entire car unloading process can be effectively controlled.

[0012] Preferably, the ship loading chute is connected to the telescopic boom through a hinge joint to form a rotatable structure, and the ship loading chute is a telescopic structure so that the position can be locally adjusted according to the loading situation.

[0013] By integrating the vertical conveying mechanism and the truck unloading mechanism into one, the present invention solves the problem of direct truck unloading for ship loading. At the same time, the vertical conveying mechanism is set as a vertical ring structure, which matches the gantry-type walking platform. The truck can directly pass through under the gantry of the walking platform and in the middle of the vertical conveying mechanism. When unloading the truck, the truck does not need to turn around and can directly drive through for unloading. The requirement for the terminal operation space is small, and a circular traffic flow can be formed in the terminal area, and the traffic organization is extremely convenient. In addition, the unloading mechanism is provided with a dust-proof seal cover and dust removal equipment, and the dust generated during the entire truck unloading process can be effectively controlled. The ship loading uses a telescopic loading chute, which can effectively reduce the dust during ship loading. The entire truck unloading and ship loading process is basically carried out in a closed environment, and the environmental protection performance is good. It has high popularization value and economic benefits for bulk cargo loading terminals with limited terminal space, inconvenient to set up fixed belt conveyors and requiring self-unloading and direct loading.

Detailed Embodiments

[0017] The present invention will be further described below with reference to specific embodiments in conjunction with the drawings:

[0018] In this embodiment, refer to Figure 1 and Figure 2, the direct unloading and direct loading bulk cargo ship loading device includes a walking platform 1, on which a telescopic ship loading mechanism 2 and a vertical lifting mechanism 3 are installed. The vertical lifting mechanism 3 forms a vertical ring structure. At the bottom of the vertical lifting mechanism 3, there is a receiving area that can directly receive the unloading of a vehicle 4 (such as a dump truck). The vertical ring structure of the vertical lifting mechanism 3 forms a passage for the vehicle 4 to directly pass through; the telescopic ship loading mechanism 2 is horizontally arranged on the walking platform 1 and extends outward from the walking platform 1 above the receiving ship 5 to form a structure for loading materials onto the ship 5; a material transfer passage is provided between the vertical lifting mechanism 3 and the telescopic ship loading mechanism 2 to form a structure for transferring materials from the vertical lifting mechanism 3 to the telescopic ship loading mechanism 2.

[0019] The vertical lifting mechanism 3 includes a vertical conveyor 32 that can circulate along the vertical ring structure, a grid plate 31, and a discharge chute 33. The vertical conveyor 32 is installed on the walking platform 1 and has a feeding passage 34 inside. The grid plate 31 is arranged above the bottom of the vertical conveyor 32 to facilitate the dispersion of materials and fall onto the vertical conveyor 32. The grid plate 31 and the lower part of the vertical conveyor 32 form a vehicle receiving hopper; the discharge chute 33 is arranged at the discharge opening above the vertical conveyor 32, and the discharge chute 33 is docked with the telescopic ship loading mechanism 2 to realize the conveyance of materials to the telescopic ship loading mechanism 2. After the materials are unloaded into the receiving hopper (i.e., the receiving area), they are lifted by the vertical conveyor 32 along the feeding passage 34 inside it, and after being lifted to the top, they are then conveyed to the telescopic ship loading mechanism 2 for ship loading.

[0020] The walking platform 1 is of a gantry structure. The telescopic ship loading mechanism 2 is installed on the upper part of the gantry, and walking wheels 11 are arranged at the bottom of the gantry. The walking wheels 11 are rubber wheels or steel wheels. The entire device can be flexibly moved through the walking wheels 11, and automatic movement can also be realized by installing a power device. The specific implementation process is prior art and will not be elaborated here.

[0021] The telescopic ship loading mechanism 2 includes a fixed boom 21, a telescopic boom 22, and a ship loading chute 23. The fixed boom 21 is installed on the walking platform 1, and the telescopic boom 22 is installed inside the fixed boom 21 to form a structure that can extend and retract along the length direction of the fixed boom 21; conveyor belts are installed on both the fixed boom 21 and the telescopic boom 22 to convey the ship loading materials; the ship loading chute 23 is connected to the end of the telescopic boom 22. After the telescopic boom 22 extends, the ship loading chute 23 will be extended above the receiving ship 5.

[0022] The vertical conveyor 32 is a chain bucket elevator, a submerged scraper conveyor, or a corrugated side conveyor. A vibrator (not shown) that can accelerate the falling of materials is installed on the grid plate 31 to prevent sticking and blockage.

[0023] On the front and rear sides of the vertical lifting mechanism 3, there are mobile car unloading platforms 6. Through the mobile car unloading platforms 6, a guiding channel for the vehicle to access the receiving area is formed, so that the vehicle 4 can drive onto the receiving area through the mobile car unloading platforms 6 for unloading. The mobile car unloading platforms 6 are fixedly connected to the walking platform 1.

[0024] The mobile car unloading platform 6 is in the form of a ramp, with a higher middle part and lower front and rear ends. The slopes of the two side mobile car unloading platforms 6 are 1:8 to 1:12, such as 1:10. The bottom of the mobile car unloading platform 6 is provided with walking tires to move along with the walking platform 1.

[0025] A sealing cover 7 is arranged on the periphery of the receiving area. The sealing cover 7 is installed on the walking platform 1 and forms a door frame shape along the receiving area so that the vehicle 4 can directly pass through. A dust removal device 8 is installed on the sealing cover 7 to absorb and remove the dust generated during vehicle unloading, so that the dust during the entire vehicle unloading process can be effectively controlled.

[0026] The ship loading chute 23 is connected to the telescopic boom 22 through a hinge joint 24 to form a rotatable structure, and the ship loading chute 23 is a telescopic structure, so that local position adjustment can be made according to the loading situation.

[0027] Working process: When ship loading operation is carried out, after the whole device walks along the wharf to the designated ship loading position, the walking wheels 11 are fixed. The self-unloading vehicle 4 loaded with bulk materials drives in from one end of the mobile car unloading platform 6, enters the receiving area surrounded by the sealing cover 7, passes through the vertical lifting mechanism 3, stops behind the mobile car unloading platform 6 on the other side, raises the hopper to unload the materials onto the grid plate 31, and then falls onto the hopper of the vertical lifting mechanism. The feed inlet of the vertical conveyor 32 is below the hopper. After the materials enter the vertical conveyor 32, they are lifted to the upper discharge port by the vertical conveyor 32, and then unloaded onto the conveyor belt of the telescopic ship loading mechanism 2 through the discharge chute 33, conveyed to the end, and then unloaded onto the ship 5 through the ship loading chute 23. The telescopic boom 22 of the telescopic ship loading mechanism can be telescoped to adjust the ship loading position to meet the requirements of different ship widths. After the vehicle 4 finishes unloading, the hopper is lowered. After getting off the mobile car unloading platform 6, it can directly drive away from the wharf operation area.

[0028] When it is necessary to change the operation position, the walking platform 1 can directly move straight along the wharf front line. The vehicle 4 does not enter for unloading temporarily and then unloads after the position is fixed.

[0029] Therefore, through the present invention, no vehicle turning is required during vehicle unloading operation, there is no need to set up a turning operation area in the wharf area, the requirement for wharf space is small, it is convenient for the traffic organization of the wharf, and at the same time, the civil construction cost of the wharf can be effectively reduced. The unloading hopper, the ship loader feeder and the ship loading device are integrated into one, and the whole machine can quickly shift the operation position. The process from vehicle unloading to ship loading is fully enclosed, effectively avoiding dust, and is green and environmentally friendly.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and cannot limit the scope of implementation of this application. That is, all equivalent changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
