[0045] Compared with the prior art, the present invention has the following advantages:

[0046] (1) The trolley wheel running rails of the present invention carrying the vertical flight reclaimer are on the outer sides of the two main booms, and the trolley is externally hung on the main boom; the horizontal wheels roll along the outer sides of the two rails, which can ensure the horizontal position between the trolley and the main boom; the anti-rollers roll against the anti-roller rails to prevent the trolley wheels from disengaging from the running rails; the main structure of the trolley is below the main boom, and the vertical flight reclaimer on the trolley is between the two main booms. The large tie rods are on the outer sides of the two main booms, and the boom flight conveyor is supported above one main boom through a support frame, avoiding the large tie rods at the inner side and providing a running passage for the vertical flight reclaimer. The trolley traction mechanism is located on the guiding boom, and the trolley traction steel wire rope enables the trolley to travel through the trolley traction pulley mechanism. The trolley is light in weight and simple in structure to reduce the moving load acting on the main boom assembly. This new layout form of the trolley, main boom and boom flight conveyor enables the functions required for the trolley to travel, the vertical flight reclaimer to lift materials and transfer them to the boom flight conveyor and other ship unloading operations to be realized.

[0047] (2) The double-layer boom unit provided by the present invention can be raised and lowered according to the water level and the ship condition, so that the travel height of the trolley is always close to the hatch, so as to reduce the material lifting height during the ship unloading operation, with high efficiency and low energy consumption. The guide boom assembly can ensure the lifting and lowering movement of the double-layer boom unit along the truss column under the action of the boom lifting wire rope. The balance boom assembly can balance the overturning moment of the vertical buried scraper feeding arm, the trolley and the main boom assembly, so that the combined center of gravity of the double-layer boom unit and all the components that follow the lifting is within the column range of the truss column, ensuring that all the boom lifting wire ropes are subjected to tension at the same time. The vertical buried scraper feeding arm can be lifted to solve the problem of changing warehouses or unloading warehouses of the ship unloader under high water level conditions when the ship is lightly loaded or empty.

[0048] (3) The arm lifting mechanism and the material reclaiming arm lifting mechanism provided by the present invention are located in the machine room, below the truss-type column and on the land side, for balancing. The center of gravity of all rotating parts can be located within the diameter of the large rotating bearing, thereby reducing the load on the large rotating bearing and the driving power of the rotating mechanism, and lowering the center of gravity of the whole machine. The truss-type column adopts an open structure, and pulleys and wire ropes can be arranged inside, so that the mechanism located in the machine room can realize the control of the double-layer arm unit and the vertical buried scraper reclaiming arm.

[0049] (4) When the ship unloader provided by the present invention is in operation, the trolley moves, and the materials extracted by the vertical buried scraper feeding arm are unloaded along the way to the arm scraper. After being transferred by the arm scraper, the materials are transferred to the swing buried scraper through the arm scraper unloading trough and the swing buried scraper feeding trough. The materials transported by the swing buried scraper are transferred to the rotating chute through the swing buried scraper unloading trough and the rotating chute feeding trough. The materials are then unloaded to the dock conveyor belt through the rotary hopper, the center hopper, and the forked chute. The swing buried scraper conveyor uses buried scrapers to transport materials, which can solve the problem of lifting materials at large inclination angles. The rotary hopper can rotate around the rotation center of the whole machine with the upper structure; the volume of the center hopper is sharply enlarged, which can reduce the material flow rate and reduce the impact of the materials on the dock conveyor belt; the forked chute can realize the material separation of the dock conveyor belt. All material lifting, transportation, and transfer are carried out continuously in a closed space, with high efficiency, low energy consumption, and good environmental performance.

[0050] (5) When the double-layer boom unit provided by the present invention is lifted or lowered, the rotating chute rotates around the rotation center of the rotating chute to perform fixed-point rotation; the swinging flight conveyor is installed on the bridge, and the feeding chute of the front swinging flight conveyor follows the lifting and lowering of the boom flight conveyor, and the discharging chute of the rear swinging flight conveyor follows the rotation of the rotating chute. To ensure the continuous conveyance of materials while maintaining the relative motion relationship among the boom flight conveyor, the swinging flight conveyor, and the rotating chute, the connection between the above three is set to be rotatable relative to each other. The feeding chute of the swinging flight conveyor is connected to the discharging chute of the boom flight conveyor and can rotate around the center of the discharging chute of the boom flight conveyor; the feeding chute of the rotating chute is connected to the discharging chute of the swinging flight conveyor and can rotate around the center of the discharging chute of the swinging flight conveyor. The connection interfaces of the boom flight conveyor, the swinging flight conveyor, and the rotating chute are adjacent and staggered in the horizontal direction, and there is a sufficient height difference in the height direction, which can ensure the smooth self-flow of materials and prevent blockage.

[0051] (6) When the ship unloader of the present invention is not in operation, it is driven by the slewing mechanism, and the truss-type column drives the double-layer boom unit, the boom flight conveyor, the swinging flight conveyor, the rotating chute, and the slewing hopper to slewing. The double-layer boom unit is parallel to the quay shoreline, and the vertical flight reclaiming boom can be placed for maintenance.

[0052] (7) When the bulk density of the material is large and the particles are uneven, the vertical flight reclaiming boom provided by the present invention can be replaced with a chain bucket elevator, the boom flight conveyor can be replaced with a belt conveyor form, and the swinging flight conveyor can also adopt a full-paved flight form, so that the application of this model is more extensive.

The slewing mechanism 24 drives the double-deck boom unit 18 and all the components located thereon to rotate through the truss-type column 5. The central chute 16 includes a rotary hopper 1601, a central hopper 1602, a bifurcated chute 1603, and a central chute support frame 1604. The central hopper 1602 and the bifurcated chute 1603 are fixedly installed on the gantry 12 through the central chute support frame 1604. The rotary hopper 1601 is connected to the central hopper 1603 and can rotate around the center of the whole machine.

[0121] The double-deck boom unit 18 moves up and down, and the rotating chute 11 and the swinging scraper conveyor unit move accordingly.

[0122] The swinging scraper conveyor unit includes a swinging scraper conveyor 17, a swinging scraper conveyor feed chute 1701, a bridge 1702, and a swinging scraper conveyor discharge chute 1703.

[0123] The swinging scraper conveyor 17 is installed on the bridge 1702. The swinging scraper conveyor feed chute 1701 is connected to the boom scraper conveyor 21, and the swinging scraper conveyor discharge chute 1703 is connected to the rotating chute 11.

[0124] The boom scraper conveyor 21, the swinging scraper conveyor 17, and the rotating chute 11 rotate relative to each other. The swinging scraper conveyor feed chute 1701 is connected to the boom scraper conveyor discharge chute 2102. The rotating chute feed chute 1101 is connected to the swinging scraper conveyor discharge chute 1703.

[0125] On one side of the gantry 12, there is a cable reel 25, and on the other side, there is a high-voltage electrical room 26; the trolley 13 moves along the quay shoreline.

[0126] During the specific implementation process:

[0127] The trolley track 180403 of the trolley 20 carrying the vertical scraper grabbing arm 19 is on the outside of the two main booms 180402, and the trolley 20 is hung on the main booms 180402; the double-layer boom unit 18 can be raised and lowered according to the water level and the ship condition, so that the travel height of the trolley is always close to the hatch, so as to reduce the material lifting height during the ship unloading operation, with high efficiency and low energy consumption. The arm lifting pulley mechanism 6, the arm lifting wire rope 4, the material head lifting pulley mechanism 3 and the material head lifting wire rope 7 can be arranged on the inner side of the truss column 5, so that the mechanism in the machine room located at the rear of the land side can realize the control of the vertical scraper grabbing arm 19 and the double-layer boom unit 18; the on-board material conveying mechanism can adapt to the relative position changes caused by the lifting of the double-layer boom unit, and the material is continuously conveyed and the transfer is smooth. The ship unloader model provided by the present invention solves the key problems of the material conveying mechanism and the difficulty in the arrangement of the mechanism of the trolley-propelled continuous ship unloader. The overall structure of the machine is reasonable, and the operation is environmentally friendly, energy-saving and efficient.

[0128] The boom lifting mechanism 9 controls the movement of the boom lifting wire rope 4. The boom lifting wire rope 4 passes through the boom lifting pulley mechanism 6 arranged on the truss column 5 and the double-layer boom unit 18, so that the double-layer boom unit 18 can move up and down along the truss column 5 to adjust the height of the main boom assembly 1804, and the number of large pull rods 1801 can be increased or decreased according to the length of the main boom assembly 1804. There is an unobstructed space between the two main booms 180402 and the large pull rods 1801, which can be used to arrange a continuous conveying mechanism and provide a walking channel for the trolley 20 with a vertical buried scraper grabber arm 19.

[0129] The horizontal wheel 2004 rolls along the outer sides of the two trolley rails 180403 to ensure the horizontal position between the trolley 20 and the main boom 180402; the trolley reverse roller 2002 rolls against the reverse roller rail 180405 to prevent the upward lifting force from causing the wheel 2001 to separate from the trolley rail 180403 when the vertical scraper feeding arm 19 is operating.

[0130] The vertical arm 180210 is connected to the main arm 180402 through the main arm frame hinge shaft 1806. The reinforcing rod 180208 adds horizontal support to the vertical arm 180210 to reduce the bending moment at the connection between the vertical arm 180210 and the guide arm frame 180201. The upper crossbeam 180203, the front tie rod 180202, the guide arm frame rear tie rod 180205, the support frame 180204 and the guide arm frame 180201 together form a stable structural system to bear the load of the main arm frame assembly 1804 and the balance arm frame assembly 1807. Four sets of guide rollers 180207 are installed on the guide arm frame 180201 and the guide frame 180206, see Figure 11 , Figure 12 .See Figure 18, the truss - type column 5 is composed of 4 columns 502 and connecting rods 503. The boom lifting track 501 is welded to the outside of the column 502. See Figure 19 , the guiding roller 180207 presses against the boom lifting track 501 from the outside to limit the horizontal displacement of the guiding boom 180201 and ensure the relative position between the double - layer boom unit 18 and the truss - type column 5. When the double - layer boom unit 18 ascends and descends along the truss - type column 5, the guiding roller 180207 rolls along the boom lifting track 501, which can reduce the frictional force and make the lifting movement flexible. As Figure 12 , the front of the guiding frame 180206 is open to reserve the space required for the movement of the swinging flight conveyor 21. See Figure 29 .

[0131] The counterweight 180704 is located at the tail of the balance boom 180702, which can balance the weights of the trolley 20, the vertical flight - type material - taking boom 19 and the main boom assembly 1804, so that the combined center of gravity of the double - layer boom unit 18 and all the lifting components located thereon is between the 4 columns 502 of the truss - type column 5, to ensure that the boom lifting steel ropes 4 between all the truss - type columns 5 and the double - layer boom unit 18 bear tension simultaneously.

[0132] The truss - type column 5 is supported on the gantry mechanism 12 through the slewing bearing 27. The driver's cab 28 is located at the lower part of the truss - type column 5, offset to one side, so that the driver can observe the operation of the vertical flight - type material - taking boom 19. The low - voltage electrical room 23 is located on both sides of the lower part of the truss - type column 5. When the slewing mechanism 24 is driven, the truss - type column 5 can drive the double - layer boom unit 18 and all the components located thereon to rotate around the rotation center of the whole machine, making the double - layer boom unit 18 parallel to the quay shoreline. As Figure 32 . In the non - operating condition, the vertical flight - type material - taking boom 19 can be placed and maintained on the quay. Below the truss - type column 5, there is space left between the 4 columns 501 in the front - to - back direction. When the double - layer boom unit 18 ascends and descends, the rotating chute 11 and the swinging flight conveyor 17 can move in this space. As Figure 29 、 Figure 30 .

[0133] The cable reel 25 and the high - voltage electrical room 26 are on both sides of the gantry to reduce the center of gravity of the whole machine. The trolley 13 travels along the quay shoreline to adjust the operation position of the whole machine on the quay.

[0134] The boom lifting mechanism 9 and the material - taking boom lifting mechanism 10 are in the machine room 8, located below the truss - type column 5 and biased towards the land side for use as counterweights. The purpose is to make the center of gravity of all the rotating parts within the diameter of the slewing bearing 27, so as to reduce the load on the slewing bearing 27 and the driving power of the slewing mechanism 24, and also to reduce the center of gravity of the whole machine.

[0135] The boom lifting wire rope 4 controlled by the boom lifting mechanism 9 enables the double-layer boom unit 18 to achieve lifting movement through the boom lifting pulley mechanism 6 arranged on the truss column 5 and the guide boom 180201. Figure 29 , Figure 30 When the water level at the dock and the loading capacity of the ship change, the main boom assembly 1804 is always close to the hatch, so that the lifting height of the material extracted from the cabin by the vertical buried scraper arm 19 on the trolley 20 is minimized, which can improve the unloading efficiency and reduce energy consumption.

[0136] When the water level is high and the ship is light and unloaded, the double-layer boom unit 18 can be lifted to the highest position, and then combined with the vertical scraper arm 19 to be lifted, the vertical scraper arm 19 can be unloaded to facilitate warehouse replacement operations or to allow the ship to leave the dock.

[0137] The trolley 20 is of traction type, light in weight, and simple in structure, and can reduce the moving load acting on the main boom 180402.

[0138] The materials transported by the arm scraper 21 are transferred to the swing buried scraper 17 through the arm scraper discharge chute 2102 and the swing buried scraper feed chute 1701. The materials transported by the swing buried scraper 17 are transferred to the rotating chute 11 through the swing buried scraper discharge chute 1703 and the rotating chute feed chute 1101. The materials are then discharged to the wharf belt conveyor 14 through the rotary hopper 1601, the central hopper 1602 and the forked chute 1603. The materials are continuously lifted, transported and transferred in a closed space, with high efficiency, low energy consumption and good environmental performance.

[0139] The central hopper 1602 and the forked chute 1603 are fixedly mounted on the gantry 12 through the central chute support frame 1604. The rotary hopper 1601 is connected to the central hopper 1603 and can rotate around the rotation center of the whole machine. When the rotary mechanism 24 is driven, the truss column 5 drives the double-layer arm unit 18, the arm scraper 21, the swing buried scraper 17 and the rotating chute 16 to rotate, and the rotary hopper 1601 can rotate with it. The volume of the central hopper 1603 is rapidly enlarged, which can reduce the material flow rate and reduce the impact of the material on the terminal belt conveyor 14.

[0140] When the double-layer arm unit 18 is raised or lowered, the lower part of the rotating chute 11 rotates at a fixed point around the rotating center of the rotating chute; the swinging scraper 17 is installed on the bridge 1702, and the front swinging scraper feeding chute 1701 follows the arm scraper 21 to rise and fall, and the rear swinging scraper discharge chute 1703 follows the rotating chute 11 to rotate. The swinging scraper 17 uses a buried scraper to transport materials, which can solve the problem of material lifting at a large inclination angle, see Figure 29。To achieve continuous material transportation while ensuring the relative motion relationship among the boom scraper conveyor 21, the swing flight conveyor 17, and the rotating chute 11, the connection between the above three is set to be rotatable relative to each other. The feed chute 1701 of the swing flight conveyor is connected to the discharge chute 2102 of the boom scraper conveyor and can rotate around the center of the discharge chute of the boom scraper conveyor; the feed chute 1101 of the rotating chute is connected to the discharge chute 1703 of the swing flight conveyor and can rotate around the center of the discharge chute of the swing flight conveyor. As Figure 28 , the connection ports of the boom scraper conveyor 21, the swing flight conveyor 17, and the rotating chute 11 are adjacent and staggered in the horizontal direction, and there is a sufficient height difference in the vertical direction, which can ensure smooth self-flow of materials and prevent blockage.

[0141] When the bulk density of the material is large and the particles are uneven, the vertical flight feeder arm 19 can be replaced with a bucket elevator (such as Figure 33 ), the boom scraper conveyor 21 can be replaced with a belt conveyor form (such as Figure 34 ), and the swing flight conveyor 17 can also adopt a full-laying scraper form (such as Figure 35 ).

[0142] The above description of the embodiments is to enable those of ordinary skill in the art to understand and use the invention. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative efforts. Therefore, the present invention is not limited to the above embodiments, and all improvements and modifications made by those skilled in the art without departing from the scope of the present invention should be within the protection scope of the present invention.
