Description

Technical Field

[0001] The invention relates to the technical field of ship loaders, and in particular to an operation method of a ship loader. Background Art

[0002] Ship loaders are large bulk material machines used for loading at bulk material terminals. They play a vital role in modern ports and industrial logistics. Among them, container ship loaders are the most widely used, with the advantages of high efficiency, large load capacity, precise positioning and high degree of automation. The existing container ship loaders' operation methods mainly include the steps of clamping containers, moving containers, placing containers and repeated loading and unloading. Among them, clamping containers is the most important step. Clamping containers mainly relies on container spreaders for clamping operations. Container spreaders are crucial to the clamping degree of containers and the stability of the moving process.

[0003] However, currently, containers are mainly lifted by interlocking the tongue plate on the sling with the buckle on the container. The connection method of the sling to the container is relatively single. During long-term use, the tongue plate and the buckle will gradually wear out due to repeated opening and closing, friction and load-bearing, which reduces the reliability of the connection and increases the possibility of failure. Moreover, the single connection method may not be able to evenly distribute the pressure when carrying heavy objects, resulting in excessive force at certain points, further increasing the risk of failure of the connection. Summary of the invention

[0004] The present invention provides a ship loader operation method, which solves the technical problem that the current lifting equipment is mainly lifted by a single clamping method of a tongue plate and a container buckle. During long-term use, the tongue plate and the buckle are worn due to repeated opening and closing, friction and load-bearing, which reduces the connection reliability and increases the risk of failure. In addition, the single connection method cannot evenly distribute the pressure when carrying heavy objects, resulting in excessive local force, further exacerbating the possibility of clamping failure.

[0005] The present invention provides a ship loader operation method, and the specific steps of the ship loader operation method are as follows:

[0006] S1. Clamping the container: The multi-stage clamping spreader is controlled by the ship loader to clamp the container.

[0007] S2. Moving containers: The loader controls the multi-stage clamping sling to lift the container from the ground to an appropriate height, and then moves it smoothly toward the ship.

[0008] S3. Placing the container: When the multi-stage clamping spreader approaches the placement position of the ship, the loader controls the multi-stage clamping spreader to slowly place the container to the required placement position, and the container spreader releases the container.

[0009] S4. Repeat loading and unloading: Complete the loading operation for all required containers according to the above steps.

[0022] In the present invention, the auxiliary card mechanism and the additional card mechanism provide additional locking and support after the initial clamping of the container, thereby improving the connection firmness between the container and the sling and reducing the risk of cargo falling due to unstable clamping. At the same time, the additional card mechanism clamps the container from the side to distribute the weight to more connection points, reducing the stress pressure on a single connection point, effectively preventing excessive local stress, reducing the risk of premature wear or failure of the existing tongue plate and buckle, and further improving the stability of the container connection.

[0023] In the present invention, a plurality of linkage mechanisms are linked together by a positioning locking mechanism. When any one of the latches fails to engage with the container successfully, the remaining latches will be automatically locked to prevent safety hazards caused by incomplete connection, and can effectively prevent the container from falling due to partial engagement failure. It can ensure that all the latches can engage with the container correctly, and avoid loose or unstable connections caused by incorrect engagement of some of the latches, thereby improving the accuracy of the overall operation.

DETAILED DESCRIPTION

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] See also Figure 1 , Figure 2 and Figure 5 The present invention provides a technical solution: a ship loader operation method, and the specific steps of the ship loader operation method are as follows:

[0040] S1. Clamping the container: The multi-stage clamping spreader 100 is controlled by the ship loader to clamp the container.

[0041] S2. Moving container: The ship loader controls the multi-stage clamping spreader 100 to lift the container from the ground to a proper height, and then moves it steadily toward the ship.

[0042] S3. Placing the container: When the multi-stage clamping spreader 100 approaches the placement position of the ship, the ship loader controls the multi-stage clamping spreader 100 to slowly place the container to the required placement position, and the container spreader releases the container.

[0043] S4. Repeat loading and unloading: Complete the loading operation for all required containers according to the above steps.

[0044] The ship loader operation method steps in the above steps S1-S4 need to be completed by the cooperation of the multi-stage clamping sling 100, the rectangular frame 10, the pull block seat 20, the alignment mechanism 30, the rotating column 40, the latch tongue 50, the linkage mechanism 60, the positioning locking mechanism 70, the auxiliary card mechanism 80 and the card adding mechanism 90.

[0045] The multi-stage clamping sling 100 includes a rectangular frame 10 with a hollow inner cavity, a fixing frame 101 fixedly connected to the rectangular frame 10, a block seat 20 arranged directly above the fixing frame 101, a main cable 102 fixedly connected to the upper end surface of the fixing frame 101 and penetrating and slidingly connected to the block seat 20, and a secondary cable 201 fixedly connected to the upper end surface of the block seat 20. The middle of the upper end surfaces of the front and rear ends of the rectangular frame 10 and the upper end surfaces of the left and right sections are provided with a positioning mechanism 30 for positioning itself to ensure that the rectangular frame 10 can be accurately connected to the container. There are two positioning mechanisms 30 located on the left and right sections of the rectangular frame 10, and there are two symmetrical left and right ... A latch tongue 50 is fixedly connected to the lower end of the column 40, and latch holes are symmetrically provided on the latch tongue 50. A coupling mechanism 60 is provided between the rotating column 40 and the alignment mechanism 30 for driving the latch tongue 50 to rotate so as to facilitate the container to be connected together. A positioning locking mechanism 70 is provided on the outside of the rotating column 40 for limiting the latch tongue 50 so that it can be fully connected with the container and can rotate normally. An auxiliary clamping mechanism 80 is provided between each latch tongue 50 and the rectangular frame 10 for further enhancing the clamping stability between the latch tongue 50 and the container. An additional clamping mechanism 90 is provided on the opposite sides of the rectangular frame 10 for clamping the left and right sides of the container to further enhance the stability when the container is connected.

[0046] See also Figure 2 and Figure 3 In this embodiment, the alignment mechanism 30 includes a support plate 301 fixedly connected to the upper end surface of the rectangular frame 10 and a rotating drum 302 hinged on the support plate 301 through a rotating shaft and a torsion spring. A pull rope 303 is fixedly connected to the outside of the rotating drum 302. The end of the pull rope 303 away from the rotating drum 302 is fixedly connected to the outside of the pull block seat 20. A folding guide plate 304 is fixedly connected to the outside of the rotating drum 302. The lower part of the folding guide plate 304 is symmetrically provided with inclined grooves 305. A guide roller 306 is slidably connected between the two inclined grooves 305 through a sliding column. A top spring 307 is fixedly connected to the upper part of the inclined groove 305.

[0047] The folding guide plate 304 is initially in a vertical downward position. When hoisting a container, the rectangular frame 10 is first moved to the top of the container, and then the main cable 102 and the secondary cable 201 are synchronously lowered through the external winding device. The rectangular frame 10 drives the folding guide plate 304 to move downward synchronously, and then the folding guide plate 304 located on the long section and the short section of the rectangular frame 10 respectively drives the guide roller 306 to move downward, and then contacts the side end surface of the container. When the guide roller 306 moves downward and contacts the upper end surface of the container, the guide roller 306 is pushed up to drive the slide column to move in the inclined groove 305, In order to avoid the rigid collision of the guide roller 306 directly hitting the container, the alignment correction of the rectangular frame 10 and the container can be completed when the folding guide plate 304 is completely moved down so that the lower part of the rectangular frame 10 hits the container, and then the secondary cable 201 is wound and rolled up through the external winding equipment, and the secondary cable 201 then drives the rotating drum 302 to rotate, and then drives the folding guide plate 304 to rotate, and the folding guide plate 304 then flips upward, and during the rotation of the rotating drum 302, the connecting mechanism 60, the auxiliary card mechanism 80 and the card adding mechanism 90 are respectively triggered to operate, so as to perform multi-level connection of the container.

[0048] See also Figure 5 and Figure 6 In this embodiment, the positioning and locking mechanism 70 includes a limiting combination groove 701 opened on the outside of the rotating column 40 and an L-shaped limiting slide plate 702 that penetrates and slides on the lower bottom plate of the rectangular frame 10 and is slidably arranged in the limiting combination groove 701. The limiting combination groove 701 is composed of a vertical groove opened along the axis of the rotating column 40 and an annular groove opened on the outside of the rotating column 40 and connected to the vertical groove. The transverse section of the L-shaped limiting slide plate 702 is slidably connected in the limiting combination groove 701. A linkage component 703 is commonly arranged on the outside of the rotating column 40. The linkage component 703 includes an open ring sleeve 7031 fixedly connected to the outside of the rotating column 40, and a transmission belt 7032 is rotatably connected to the outside of the open ring sleeve 7031.

[0049] The L-shaped limiting slide plate 702 is initially in a naturally drooping state, the transverse section of the L-shaped limiting slide plate 702 is located in the vertical groove in the limiting combination groove 701, and the rotating column 40 is in a locked state. When the rectangular frame 10 moves down to its lower part and abuts against the container, the vertical section of the L-shaped limiting slide plate 702 also abuts against the container and is pushed up until the transverse section of the L-shaped limiting slide plate 702 is completely moved up and enters the annular groove of the limiting combination groove 701. At this time, the rotating column 40 can rotate normally. When the rectangular frame 10 is not completely aligned with the container, the transverse section of the L-shaped limiting slide plate 702 is not pushed up and moves into the limiting combination groove. In the annular groove in 701, the rotating column 40 is in a stuck state, and the transmission belt 7032 and the open ring sleeve 7031 can prevent the remaining rotating columns 40 from rotating normally, and then the connecting mechanism 60 cannot be triggered to run, and then the rotating drum 302 cannot be rotated normally by the secondary cable 201, so that when the rectangular frame 10 is not fully aligned with the container, the subsequent latching tongue 50, auxiliary latching mechanism 80 and additional latching mechanism 90 cannot be normally engaged with the container, avoiding the situation where the rectangular frame 10 is not fully aligned with the container and then connected, resulting in the container falling due to the inadequate engaging points during lifting.

[0050] See also Figure 4 and Figure 6 In this embodiment, the linkage mechanism 60 includes a door-shaped inner frame 601 slidably connected to the upper end surface of the rectangular frame 10 by connecting a telescopic column, a spiral groove 602 is rotationally symmetrically opened on the outside of the rotating column 40, and the opposite sides of the vertical section of the door-shaped inner frame 601 are fixedly connected with a lifting column 603 slidably set in the spiral groove 602, and a pulling component 604 is jointly set between the door-shaped inner frame 601 and the rotating drum 302, and the pulling component 604 includes a vertical section of the door-shaped inner frame 601. There are a slide groove 6041 on the opposite side of the segment, a slider 6042 slidably connected in the slide groove 6041, and a door-type outer frame 6043 fixedly connected to the upper end surfaces of the two sliders 6042 and slidably sleeved on the outside of the door-type inner frame 601, the upper end surface of the door-type outer frame 6043 is hinged with a connecting rod 6044 through a lug, and the end of the connecting rod 6044 away from the lug is hinged to the rotating drum 302 through a connecting column, and the upper groove wall of the slide groove 6041 is fixedly connected to a limiting spring 6045.

[0051] When the rotating drum 302 is pulled and rotated, the door-shaped outer frame 6043 is pulled upward through the connecting rod 6044, and the door-shaped outer frame 6043 then drives the slider 6042 to move upward, and the slider 6042 then contacts the limit spring 6045 and pushes the door-shaped inner frame 601 upward, and the door-shaped inner frame 601 then drives the lifting column 603 to move upward and squeezes the spiral groove 602 to rotate the rotating column 40, and the rotating column 40 then drives the latch tongue 50 to rotate, and after the latch tongue 50 rotates, it drives the external latch mouth of the latch tongue 50 to engage with the latch buckle on the container, so that the container can be connected in the first step, and then the rotating column 40 stops rotating, and the door-shaped outer frame 6043 continues to move upward under the pulling of the connecting rod 6044, and drives the slider 6042 to move upward and push the limit spring 6045 to be compressed.

[0052] See also Figure 7 and Figure 8 In this embodiment, the auxiliary card mechanism 80 includes two installation grooves 801 symmetrically opened in the tongue 50 and connected to the bayonet, a V-shaped card frame 802 is slidably connected in the installation groove 801, a compression spring 803 is fixedly connected between the V-shaped card frame 802 and the installation groove 801, and a push-up assembly 804 for driving the V-shaped card frame 802 to move is jointly arranged between the tongue 50 and the rectangular frame 10, and the push-up assembly 804 includes two Z-shaped grooves 8041 symmetrically opened on the tongue 50 corresponding to and connected to the installation groove 801, a Z-shaped push rod 8042 is slidably connected in the Z-shaped groove 8041, and an arc protrusion 8043 cooperating with the Z-shaped push rod 8042 is symmetrically fixedly connected to the lower end surface of the rectangular frame 10.

[0053] When the latch tongue 50 rotates, it will also drive the Z-shaped push rod 8042 to rotate synchronously. The Z-shaped push rod 8042 rotates and hits the arc-shaped protrusion and is pushed downward by the arc-shaped protrusion. The Z-shaped push rod 8042 moves downward and hits the inclined surface on the upper part of the V-shaped frame 802. The V-shaped frame is then pushed to move away from the axis of the rotating column 40. After moving, the V-shaped frame 802 tightly hits the buckle on the container, thereby further enhancing the stability of the connection between the latch tongue 50 and the container, completing the second step of snap-on connection of the container.

[0054] See also Fig. 9 , Fig.10 and Fig.11In this embodiment, the card adding mechanism 90 includes an installation box 901 fixedly connected to the side end surface of the rectangular frame 10, and the front and rear cavity walls of the installation box 901 are provided with guide grooves 902, and the guide groove 902 is composed of a vertical section and an inclined section connected to the lower end of the vertical section. A card plate 904 is slidably connected between the two guide grooves 902 through a sliding column 903. A through groove is provided at the lower part of one side of the installation box 901 close to the rectangular frame 10, and a pressing and shifting group for pushing the card plate 904 to move is provided between the installation box 901 and the rotating drum 302 located on the front and rear sections of the rectangular frame 10. Part 905, the pressure-shifting assembly 905 includes a sliding rod 9051 that is slidably connected to the installation box 901, a return spring 9052 is fixedly connected between the sliding rod 9051 and the upper cavity wall of the installation box 901, the rotating cylinder 302 located on the front and rear sections of the rectangular frame 10 is fixedly connected to the outside with an arc gradual squeezing block 9053 that cooperates with the sliding rod 9051, a U-shaped groove is opened on the clamping plate 904, and the front and rear groove walls of the U-shaped groove are both opened with transverse grooves 9054, and the sliding rod 9051 is symmetrically fixedly connected to the outside with a sliding bar block 9055 that is slidably set in the transverse groove 9054.

[0055] When the rotating drum 302 located on the front and rear sections of the rectangular frame 10 rotates, it also drives the position of the arc-shaped gradually squeezing block to change continuously. The arc surface of the arc-shaped gradually squeezing block then contacts the upper end of the sliding rod 9051 and pushes the sliding rod 9051 downward. The sliding rod 9051 then drives the card plate 904 to move downward through the sliding bar block 9055. During the downward movement of the card plate 904, the sliding column 903 is driven to slide down in the guide groove 902. When the sliding column 903 moves down to the inclined section position of the guide groove 902, it will be squeezed and move toward the container. The sliding column 903 drives the card plate 904 to move until the card plate 904 touches the container. At this time, the card plate 904 contacts the edge of the container side, so that the container can be clamped and limited from the side, and the third step of the container clamping connection can be completed. The multiple clamping of the container greatly enhances the connection between the multi-stage clamping spreader 100 and the container, ensuring the stability of the container lifting.

[0056] Finally, after the container is moved to the designated position, the secondary pull rope 201 is released, and the erected folding guide plate 304 droops to drive the rotating drum 302 to reverse, and the rotating drum 302 then respectively triggers the connecting mechanism 60, the auxiliary card mechanism 80 and the card adding mechanism 90 to run in the opposite direction, so that the tongue 50 is separated from the buckle, the V-shaped card frame 802 is separated from the buckle, and the card plate 904 is removed from the container, which can facilitate the rapid separation of the rectangular frame 10 from the container.
