Description

Technical Field

[0001] The invention relates to the technical field of bulk cargo ship unloading equipment, in particular to a novel continuous chain bucket ship unloader. Background Art

[0002] There are many types of bulk materials, and their characteristics (such as bulk density, fluidity, particle size, etc.) vary greatly. Chain bucket continuous ship unloader is an ideal environmentally friendly ship unloader model. At present, the more mature model is the L-type continuous chain bucket ship unloader.

[0003] like Fig.13 The working characteristics of the L-type continuous chain bucket ship unloader are that the chain bucket lifting system rotates by itself, driving the L-type reclaiming head below to rotate and reclaim materials; the chain bucket lifting system lifts the materials and unloads them to the platform feeder; the platform feeder feeds the materials to the arm frame belt conveyor; the materials are conveyed to the wharf belt conveyor system via the internal belt conveyor. The arm frame can rotate and pitch, and the whole machine can walk along the wharf to adjust the spatial position of the L-type reclaiming head. The working characteristics of the L-type continuous chain bucket ship unloader cause the following problems:

[0004] 1. The chain bucket lifting system needs to be equipped with a slewing mechanism to realize the material retrieving operation by rotating relative to the boom; and the lifted materials must be unloaded to the platform feeder before they can be rotated to feed the boom belt conveyor. This system has a complex structure and heavy weight. Since this system is located at the front of the boom, it has a great impact on the weight of the whole machine, the wheel pressure of the dock, etc., and also makes the whole machine cost relatively high. When the productivity is high and the material particle size difference is relatively large, the platform feeder is prone to material blocking.

[0005] 2. If Fig.14 and Fig.15 As shown in the figure, the L-shaped chain bucket reclaiming head under the chain bucket lifting system realizes the reclaiming operation by rotating. Fig.14 This is a schematic diagram of the L-type chain bucket reclaimer structure. Fig.15 The left view of the L-shaped chain bucket reclaiming head is a schematic diagram. The chain bucket moves linearly under the traction of the chain and also rotates with the reclaiming head. The two directions of movement are perpendicular to each other, so the excavated material can only enter the hopper from the chain bucket corner. The impact of this operation mode is: (1) The effective width of the chain bucket cutting the material is narrow, the excavation force is small, and the unloading productivity is limited. (2) In order to ensure that the material can fill the hopper during the reclaiming stage, the hopper width H (see Fig.15 ) is relatively small. At the same time, in order to ensure productivity, that is, to ensure the volume of the hopper, the hopper depth D can only be increased (see Fig.15 ). As the hopper is relatively deep, it is not easy to unload completely during the unloading stage, and it is easy to generate material return. (3) The chains are on both sides of the hopper. When the reclaiming head rotates to reclaim materials, the chains come into contact with the materials and are easily worn, making the maintenance cost relatively high.

[0006] 3. If Fig.13, L-type continuous chain bucket ship unloader uses arm belt conveyor to transfer materials. When the water level difference of the dock or the ship type changes greatly, the arm downward angle increases accordingly (such as Fig.10 ), the material may slide down and cannot be transported upward. Therefore, the application scenarios of L-type continuous chain bucket ship unloader are limited.

[0007] The Chinese invention patent with the publication number of CN111606080A discloses a novel linear reciprocating high-efficiency intelligent environmentally friendly continuous chain bucket ship unloader, including a chain bucket material taking mechanism, which is fixed on the trolley assembly and moves along the track on the arm frame mechanism with the trolley assembly, and the arm frame mechanism is equipped with an arm frame belt connected to the discharge port of the chain bucket material taking mechanism and a transfer belt docked with the arm frame belt, and the output end of the transfer belt is docked with the unloading belt through the transfer hopper, and the output end of the unloading belt is docked with the dock belt conveyor arranged on the dock through the central hopper; it also includes a trolley walking system mechanism, a guide cylinder is vertically installed on the gantry, a slewing mechanism is installed on the arm frame mechanism and is sleeved on the guide cylinder and rotates around it, and the arm frame mechanism is also equipped with a lifting mechanism that controls it to slide up and down along the guide cylinder. The present invention meets the unloading requirements of different ship types and different working conditions, has high efficiency and low cost, is convenient to use and has a long service life, and improves the utilization rate of the unloading space on the dock shoreline. However, in this patent, the trolley is equipped with a chain bucket reclaiming mechanism, so the moving wheel pressure of the trolley on the boom is large, making the boom structure complex and the weight of the whole machine heavy; during the ship unloading operation, the trolley moves, and the discharge port of the chain bucket reclaiming mechanism moves back and forth relative to the boom, making material transportation complicated and prone to dust leakage; the boom lifting mechanism drives the boom to rise and fall along the guide cylinder to adjust the height direction of the working surface of the chain bucket reclaiming mechanism. This system is complex in composition and has a large load, which is the main factor for the heavy weight of the whole machine. Summary of the invention

[0008] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a continuous chain bucket ship unloader with a new operating mode and structural type, so that the bucket can face the material and take materials in a positive direction, with strong digging force; a shallow and wide bucket type is adopted, which is easy to fill and unload; the chain has less wear and long service life; the material conveying system is simple and the material is not easy to be blocked; the productivity is high and the application is wide; the whole machine is light in weight and low in cost.

[0009] The purpose of the present invention can be achieved by the following technical solutions:

[0010] A new type of continuous chain bucket ship unloader, including a chain bucket excavation and lifting system, a connecting rod system, an arm assembly, an arm buried scraper conveying system, an arm bracket, a discharge chute system, a slewing mechanism, a slewing platform, a slewing bearing, a fixed chute system and a dock belt conveyor;

[0011] The chain bucket excavation and lifting system is connected to the head of the boom assembly through a connecting rod system, and rotates with the boom assembly to drive the material taking head to move;

[0012] The arm assembly supports the arm bracket;

[0013] The arm support is located on the slewing platform, and the slewing mechanism is arranged on the slewing platform. When the slewing mechanism is working, it drives the slewing platform and all the components supported on the platform, including the unloading chute system, to rotate around the slewing center of the slewing bearing, so that the arm assembly drives the chain bucket excavation and lifting system and the arm buried scraper conveying system to rotate around the slewing center of the slewing bearing;

[0014] The chain bucket excavation and lifting system digs and lifts the materials from the cabin, and then drops the materials to the arm buried scraper conveying system, and then transports them to the wharf belt conveyor through the unloading chute system and the fixed chute system.

[0015] Furthermore, the arm-embedded scraper conveying system adopts a hollow scraper or a full-covered scraper type.

[0016] Furthermore, the boom assembly includes a lower hinge point of the chain bucket support, a boom structure, a front pull rod A, a front pull rod B, a tower, a rear pull rod, a counterweight and a boom hinge point.

[0017] Further, the boom assembly is supported on the boom bracket via the boom hinge;

[0018] The tower is located above the boom structure, and the counterweight is located at the land side tail of the boom structure.

[0019] Furthermore, on the seaward side of the boom assembly, the tower is connected to the boom structure via a front tie rod A and a front tie rod B;

[0020] On the side of the boom assembly close to the land, the tower is connected to the boom structure through a rear tie rod to balance the loads of the front tie rods A and B.

[0021] Furthermore, it also includes a gantry system and a trolley traveling mechanism. The gantry system is supported below the revolving platform and arranged above the trolley traveling mechanism. The trolley traveling mechanism drives the whole machine to move along the dock shoreline to adjust the position of the whole machine along the dock shoreline.

[0022] Furthermore, the boom assembly and the slewing platform are connected via a pitch cylinder, and when the pitch cylinder is extended and retracted along its own axis, the boom assembly rotates around the boom hinge.

[0023] Further, the connecting rod system includes an upper hinge point of a chain bucket bracket, a chain bucket bracket, a connecting rod, a connecting rod rear bracket and a connecting rod rear hinge point;

[0024] The chain bucket excavation and lifting system is installed on the chain bucket bracket;

[0025] The chain bucket bracket is rotatably connected to the arm structure through the lower hinge point of the chain bucket bracket, and is rotatably connected to the connecting rod through the upper hinge point of the chain bucket bracket;

[0026] The connecting rod is rotatably connected to the connecting rod rear bracket through the connecting rod rear hinge point;

[0027] The connecting rod rear bracket is fixedly installed on the rotating platform.

[0028] Furthermore, when the connecting rod system rotates with the boom assembly, the lower hinge point of the chain bucket bracket follows the boom structure to rotate around the boom hinge point; the upper hinge point of the chain bucket bracket rotates around the lower hinge point of the chain bucket bracket and follows the connecting rod to rotate around the rear hinge point of the connecting rod.

[0029] Furthermore, the chain bucket excavation and lifting system includes a chain bucket material taking head, which remains perpendicular to the main axis plane of the boom assembly. When the boom assembly rotates clockwise or counterclockwise, the chain bucket material taking head rotates with the boom assembly and excavates the material directly in front of its opening direction, thereby realizing two-way frontal material taking operation.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] (1) The chain bucket excavation and lifting system is installed on the boom head through a connecting rod system. The direction of the reclaiming head is kept perpendicular to the boom main axis plane and can always be perpendicular to the horizontal plane. During ship unloading operations, the chain bucket excavation and lifting system rotates with the boom to drive the reclaiming head to move. The chain bucket excavates the material in its direction of movement, and can realize two-way frontal backsweeping and reclaiming. The excavation force is large and the efficiency is high. The materials operated by the chain bucket excavation and lifting system can be directly dropped into the boom buried scraper conveying system without the need for feeding and switching. The materials are not easy to be blocked and the productivity is stable.

[0032] (2) When the chain bucket reclaiming head rotates clockwise or counterclockwise with the arm, the material is located in front of the chain bucket opening direction, and the bucket mouth can cut the material in both directions to realize material reclaiming. The bucket mouth is wide and the bucket depth is narrow, so the material is easy to fill and empty, with less return material and high productivity. The chain is behind both sides of the chain bucket to avoid direct contact with the material, with less wear and long service life.

[0033] (3) The boom material conveying system adopts buried scraper type; according to the different characteristics of the materials, hollow scraper or full-covered scraper type can be used. This system can ensure the stable and continuous conveying of materials along the boom under the condition of large changes in the pitch angle of the boom. This makes this model suitable for unloading operations of ships of different sizes at docks with large changes in water level differences.

[0034] (4) The whole machine has a novel structure, a reasonable material handling method, and a simple material conveying system, making the whole machine light in weight, low in energy consumption, high in productivity and stable. It is an environmentally friendly continuous ship unloading equipment that can be widely used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0052] Example 1

[0053] like Figure 1 As shown, a novel continuous chain bucket ship unloader comprises a chain bucket excavation and lifting system 1, a connecting rod system 2, a boom assembly 3, a boom buried scraper conveying system 4, a boom bracket 5, a discharge chute system 6, a slewing mechanism 7, a slewing platform 8, a slewing bearing 11, a fixed chute system 12 and a wharf belt conveyor 13; the chain bucket excavation and lifting system 1 is connected to the head of the boom assembly 3 through the connecting rod system 2, and rotates with the boom assembly 3 to drive the material taking head to move; the boom assembly 3 supports the boom bracket 5; the boom bracket 5 is located on the slewing platform 8, and rotates The mechanism 7 is arranged on the slewing platform 8. When the slewing mechanism 7 is working, it drives the slewing platform 8 and all the components supported on the platform, including the unloading chute system 6, to rotate around the rotation center of the slewing bearing 11, so that the arm assembly 3 drives the chain bucket excavation and lifting system 1 and the arm buried scraper conveying system 4 to rotate around the rotation center of the slewing bearing 11; the chain bucket excavation and lifting system 1 digs and lifts the materials from the cabin, and then drops the materials to the arm buried scraper conveying system 4, and then transports them to the wharf belt conveyor 13 through the unloading chute system 6 and the fixed chute system 12. During the unloading process, the materials are continuously transported in a closed space, and the transportation process is simple, dust-free, and the productivity is stable and the energy consumption is low.

[0054] The chain bucket excavation and lifting system 1 includes a chain bucket system discharge chute 101 and a chain bucket material taking head 102. The chain bucket material taking head 102 remains perpendicular to the main axis plane of the boom assembly 3. When the boom assembly 3 rotates clockwise or counterclockwise, the chain bucket material taking head 102 rotates with the boom assembly 3, and excavates the material just in front of its opening direction, and drops the material through the chain bucket system discharge chute 101 to the boom buried scraper conveying system 4, realizing a two-way frontal material taking operation with large excavation force and high efficiency.

[0055] like Figure 1-Figure 3 As shown, the arm support 5 is located on the slewing platform 8. When the slewing mechanism 7 is working, the slewing platform 8 and all the components supported on the platform, including the unloading chute system 6, can rotate around the slewing center of the slewing bearing 11. Therefore, the arm assembly 3 can drive the chain bucket excavation and lifting system 1 and the arm buried scraper conveying system 4 to rotate around the slewing center. When the arm rotates, the chain bucket material taking head 102 of the chain bucket excavation and lifting system 1 faces the material in its moving direction to perform bidirectional frontal material taking, which can form a horizontal plane as shown in the figure. Figure 6 The material taking operation surface is shown.

[0056] like Figure 3 As shown, the driver's cab 15 is arranged on one side of the boom assembly 3 for the driver to operate and control the ship unloader, and the machine room 16 is symmetrically arranged on both sides of the gantry system 9.

[0057] like Figure 7 As shown, in this embodiment, the arm buried scraper conveying system 4 uses a hollow scraper, which has a simple structure and light weight, and can convey various types of block, granular and powdery bulk goods with relatively uniform particles, ensuring that when the arm pitch angle changes greatly, such as Fig.10 and Fig.11 As shown, the material can be transported stably and continuously along the boom. Fig.10 D in the middle is the maximum downward angle of the boom. Fig.11 E in the middle is the maximum upward angle of the arm.

[0058] like Figure 4 As shown, the arm assembly 3 includes a lower hinge point 301 of the chain bucket support, an arm structure 302, a front tie rod A303, a front tie rod B304, a tower 305, a rear tie rod 306, a counterweight 307 and an arm hinge point 308. The arm assembly 3 is supported on the arm support 5 through the arm hinge point 308. The pitch cylinder 14 connects the arm assembly 3 and the slewing platform 8. When the pitch cylinder 14 is extended or retracted, the arm assembly 3 rotates around the arm hinge point 308, and the height of the lowest chain bucket reclaiming head 102 of the chain bucket excavation and lifting system 1 relative to the dock surface can be adjusted to achieve the adjustment of the reclaiming operation surface in the height direction, such as Fig.10 and Fig.11 As shown, the ship unloader can operate under different dock water level heights and cabin depths.

[0059] like Figure 4 As shown, the tower 305 is located above the boom structure 302, and the counterweight 307 is located at the land side tail of the boom structure 302. On the sea side of the boom assembly 3, the tower 305 is connected to the boom structure 302 through the front tie rod A303 and the front tie rod B304, which can improve the force of the boom structure 302 under the load of the chain bucket excavation and lifting system 1 located at the front end thereof. On the side of the boom assembly 3 close to the land, the tower 305 is connected to the boom structure 302 through the rear tie rod 306 to balance the load of the front tie rod A303 and the front tie rod B304, and can improve the force of the boom structure 302 under the action of the counterweight 307. The function of the counterweight 307 is to: make the combined center of gravity of all rotating parts close to the rotation center of the slewing bearing 11 to reduce the load of the slewing mechanism 7; balance the wheel pressure of the trolley running mechanism on the sea and land sides to reduce the load on the wharf; and improve the stability of the whole machine. The number of front tie rods can be adjusted according to the width of the unloaded ship, that is, the length of the boom structure 302 on the sea side. Only one front tie rod can be retained or more front tie rods can be added.

[0060] like Figure 6 As shown, when the arm assembly 3 rotates clockwise or counterclockwise, the chain bucket reclaiming head 102 rotates with the arm assembly 3, and the chain bucket excavates the material in front of its opening direction, so as to realize the bidirectional front reclaiming operation. The bucket mouth is wide, and the excavation force is large; the bucket is deep and narrow, and the material is easy to fill and empty. The chain is behind both sides of the chain bucket to avoid direct contact with the material, with less wear and long service life.

[0061] The gantry system 9 is supported on the trolley travel mechanism 10. Fig.12 As shown, the trolley travel mechanism 10 enables the whole machine to travel along the dock shoreline to adjust the position of the whole machine along the dock shoreline. Fig.12 In the figure, F is the angle at which the boom can rotate, and G is the direction in which the trolley moves. Fig.10 and Fig.11 As shown, with the cooperation of the pitch cylinder 14, the chain bucket excavation and lifting system 1 can enter various hatches of the ship to carry out ship unloading operations, and can also be lifted above the hatches so that the ship can leave the dock.

[0062] like Figure 5 As shown, the chain bucket excavation and lifting system 1 is installed on the chain bucket bracket 202. The chain bucket bracket 202 is connected to the arm structure 302 through the chain bucket bracket lower hinge 301, and is connected to the connecting rod 203 through the chain bucket bracket upper hinge 201. The connecting rod 203 is connected to the connecting rod rear bracket 204 through the connecting rod rear hinge 205, and the connecting rod rear bracket 204 is fixedly installed on the rotating platform 8. Fig. 9As shown in the figure, A is the motion trajectory of the upper hinge point 201 of the chain bucket support, B is the motion trajectory of the connecting rod 203, and C is the motion trajectory of the lower hinge point 301 of the chain bucket support. When the boom is pitched, the lower hinge point 301 of the chain bucket support follows the boom structure 302 to rotate around the boom hinge point 308; the upper hinge point 201 of the chain bucket support rotates around the lower hinge point 301 of the chain bucket support, and follows the connecting rod 203 to rotate around the rear hinge point 205 of the connecting rod. When the boom system 2 is pitched, this system can ensure that the installation surface of the chain bucket excavation and lifting system 1 on the chain bucket support 202 remains horizontal, that is, the chain bucket excavation and lifting system 1 is always perpendicular to the horizontal plane, so that it can realize the material removal operation in the warehouse and the adjustment operation of the warehouse in and out.

[0063] Example 2

[0064] In this embodiment, the arm-mounted scraper conveying system 4 adopts a full-spread scraper type, which can solve the problem of large-angle conveying of bulk cargo with large particle size differences and very good fluidity. If such materials are conveyed upward at a large angle using a hollow scraper, a part of them may be missed and the entire scraper cross-section cannot be filled, thereby affecting the conveying productivity. Figure 8 As shown in Figure 2, when the boom pitch angle changes greatly, such as Fig.10 and Fig.11 As shown, the material can be stably and continuously transported along the arm. The rest of the structure is the same as that of embodiment 1.
