Description

Technical Field

[0001] The present invention relates to the technical field of container lifting, and in particular to a port container lifting device. Background Art

[0002] In the field of port logistics and transportation, container loading and unloading operations are extremely critical, and port container cranes, as the core equipment responsible for this task, play an indispensable role. With the continuous advancement of technology, the remote control system of port container cranes has brought new changes to port container loading and unloading operations. This remote control system realizes remote and precise control of the crane's spreader. With the help of sensors, cameras and other equipment, operators can obtain all-round, high-definition images of the crane operation site and relevant operating parameter information in real time from a control room far away from the crane, accurately judge the position and posture of the container, and realize the lifting of the container.

[0003] During container lifting operations at ports, the complexity of the container terminal environment and the relatively narrow port operating space mean that when multiple cranes operate simultaneously in the same area, the motion trajectories of the spreaders on each crane may intersect with each other. This intersecting motion trajectory increases the probability of collision accidents. Once a collision accident actually occurs, it often causes the surface of the container to suffer impact force, resulting in dent damage.

[0004] In order to solve the above problems, this application proposes a port container lifting equipment. Summary of the Invention

[0005] The present invention proposes a port container lifting equipment, which solves the problem in related technologies that port container terminals are complex and narrow, the movement trajectories of the spreaders intersect when multiple cranes are operating, the probability of collision increases, and the container surface is easily damaged by impact and dents.

[0006] The present invention provides a port container lifting device comprising a crane, a protection frame and a traction module;

[0007] The crane is provided with a sling via a steel rope;

[0008] The outer periphery of the sling is installed with a loading frame, and rod-type plug-ins are slidably connected on all four sides of the loading frame. The protective frame is installed at the bottom ends of the four rod-type plug-ins. Elastic buffer modules are installed on all four sides of the loading frame and are respectively mounted on the four rod-type plug-ins. V-shaped protective parts are hinged on all four sides between the loading frame and the protective frame, and an angle is formed on the V-shaped protective parts.

[0009] The V-shaped guard has a first position state and a second position state. When the V-shaped guard is in the first position state, it is in a folded position. When the V-shaped guard is in the second position state, it is in an expanded position. The traction module can drive the guard frame to move up and down, so that the V-shaped guard can freely switch the position state.

[0010] When the V-shaped protective member is hit, the deformation angle increases, and the protective frame is pushed to drive the rod-type plug-in on it to move downward, squeezing the elastic buffer module.

[0011] As a further optimization scheme of the present invention, the V-shaped protective member includes a first protective rod and a second protective rod, the adjacent ends of the first protective rod and the second protective rod are hinged to each other, and the ends away from the first protective rod and the second protective rod are hinged to the loading frame and the protective frame respectively, the first protective rod and the second protective rod form a V-shaped structure, and the angle is formed between the first protective rod and the second protective rod.

[0012] As a further optimization scheme of the present invention, the rod-type plug-in includes an insertion rod, and four insertion rods slide through the four sides of the loading frame respectively. The protective frame is installed at the bottom ends of the four insertion rods. The insertion rods are provided with end blocks located above the elastic buffer module, and the end blocks are threadedly connected with bolts that are tightly pressed against the insertion rods.

[0013] As a further optimization scheme of the present invention, the elastic buffer module includes a fixed tube, and fixed tubes are installed on all four sides of the loading frame. The four fixed tubes are respectively mounted on four insertion rods. The fixed tube is equipped with an elastic buffer that is slidably mounted on the insertion rod and located below the end block. The outer periphery of the fixed tube is equipped with a limiting part for limiting the elastic buffer.

[0014] As a further optimization scheme of the present invention, the elastic buffer includes a spring and a buffer disk. The spring is installed at the top end of the fixed tube and is sleeved on the insertion rod. The buffer disk is installed at the top end of the spring and is slidably sleeved on the insertion rod, and the buffer disk is located below the end block.

[0015] As a further optimization solution of the present invention, the limiting member includes a loading tube and a magnetic rod. The loading tube is installed on the outer periphery of the fixed cylinder. Magnetorheological fluid is provided in the loading tube. A magnetic rod inserted into the loading tube is installed at the bottom of the buffer tray.

[0016] As a further optimization solution of the present invention, a pressure warning component is installed on the buffer tray. When the insertion rod drives the end block to move downward and squeeze the buffer tray, an early warning can be given through the pressure warning component.

[0017] As a further optimization solution of the present invention, the pressure warning component includes a pressure sensor and an alarm. The pressure sensor is installed on the top of the buffer tray and located below the end block. The alarm is installed on the side of the loading frame. The pressure sensor is connected to the alarm.

[0018] As a further optimization scheme of the present invention, the traction module includes a fixed block, fixed blocks are installed on both sides of the loading frame, a motor is installed on the side of the fixed block, the output end of the motor is connected to a winding member, and the bottom end of the winding member is connected to the protective frame.

[0019] As a further optimization scheme of the present invention, the winding member includes a roller and a traction rope, the output end of the motor is connected to the roller, the traction rope is wound on the roller, two openings are symmetrically opened on the loading frame, the bottom ends of the two traction ropes pass through the two openings respectively, the bottom ends of the two traction ropes are connected to elastic ropes, and the two elastic ropes are respectively connected to the two sides of the protective frame.

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. Before lifting a container, the V-shaped guard between the loading frame and the protective frame is in a retracted position. The crane then drives the sling on the steel rope to lift the container. During the lifting process, to prevent the container from colliding with other objects, the traction module can be used to drive the protective frame downward along the container, so that the V-shaped guard between the protective frame and the loading frame switches to an extended position. Since the V-shaped guards are hingedly connected on all sides between the loading frame and the protective frame, protection can be formed on all sides of the container. This design can effectively prevent the container from directly colliding with other objects, reducing the probability of collision accidents, thereby ensuring the safety of port container lifting operations, reducing the risk of personal injury and equipment damage caused by collisions, and improving the overall safety of port operations.

[0022] 2. During the lifting process of the present invention, when a collision occurs, the V-shaped guards distributed on the outer periphery of the container can be pre-stressed for protection. After the force is applied to the V-shaped guards, the deformation angle increases, and the protective frame at the bottom thereof is pushed downward. When the protective frame moves downward, it can drive the rod-type plug-in thereon to move downward with it, squeezing the elastic buffer module. After being squeezed, the elastic buffer module deforms and elastically cushions, which can effectively absorb the impact force generated by the collision, prevent the impact force from directly acting on the container surface, avoid dents and damage to the container, ensure the integrity of the container, reduce maintenance costs, and increase the service life of the container, while also ensuring the safe transportation of goods;

[0023] 3. Driven by the protective frame, the rod-type plug-in of the present invention moves downward and compresses the elastic buffer on the fixed tube. When the elastic buffer is subjected to force, it pushes the magnetic rod downward in the loading tube. Because the loading tube is provided with magnetorheological fluid, the magnetorheological fluid gradually hardens as the magnetic rod moves downward, thereby limiting the elastic buffer and preventing excessive buffering. This mechanism can control the buffering process, ensuring that the buffering force is always within a reasonable range when a collision occurs. This buffering control not only improves the stability and reliability of the equipment in the event of a collision, but also extends the equipment's service life and reduces maintenance costs. It also provides safer and more reliable protection for port container lifting operations and enhances the adaptability and stability of the entire lifting equipment in complex operating environments.

[0024] 4. When the protective frame of the present invention moves downward, it can drive the surrounding insertion rods to move downward along with it. The insertion rods drive the end blocks thereon to squeeze the buffer plate. Since the buffer plate is equipped with a pressure warning component, an alarm can be issued in time through the pressure warning component. This warning function can remind the operators at the first time when a collision occurs, so that they can quickly take corresponding emergency measures, thereby further reducing the losses caused by the collision, improving the emergency handling capabilities of port operations, and enhancing the overall safety and reliability of port container lifting operations.

[0037] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0038] like Figure 1-11 As shown, a port container lifting device proposed by the present invention includes a crane 1, a protection frame 4 and a traction module 7;

[0039] A sling 102 is mounted on the crane 1 via a steel rope 101;

[0040] The outer periphery of the sling 102 is mounted with a loading frame 2, and rod-type plug-ins 3 are slidably connected to the four sides of the loading frame 2. A protective frame 4 is mounted on the bottom ends of the four rod-type plug-ins 3. Elastic buffer modules 5 are mounted on the four sides of the loading frame 2 and are respectively mounted on the four rod-type plug-ins 3. V-shaped protective members 6 are hinged on the four sides between the loading frame 2 and the protective frame 4, and an angle is formed on the V-shaped protective member 6.

[0041] The V-shaped guard 6 has a first position state and a second position state. When the V-shaped guard 6 is in the first position state, it is in a retracted position. When the V-shaped guard 6 is in the second position state, it is in an extended position. The traction module 7 can drive the protection frame 4 to move up and down, so that the V-shaped guard 6 can freely switch the position state.

[0042] When the V-shaped protective member 6 is hit, the deformation angle increases, and the protective frame 4 is pushed to drive the rod-type plug-in 3 thereon to move downward, thereby squeezing the elastic buffer module 5 .

[0043] During actual operation of the present invention, the crane 1 lowers the spreader 102 to the container position through the steel rope 101 to complete the grabbing of the container. Before grabbing, the V-shaped protective member 6 is in the first position of the folded state, which does not affect the normal grabbing operation of the spreader 102 on the container. When it is necessary to lift the container, the traction module 7 is started, and the traction module 7 drives the protective frame 4 to move down along the container. Since the protective frame 4 is slidably connected to the loading frame 2 through the rod-type plug-in 3 and the V-shaped protective member 6 is hinged on all sides, during the downward movement of the protective frame 4, the V-shaped protective member 6 gradually switches from the folded posture to the expanded posture, forming a protective barrier around the container. During the lifting process, if an object accidentally approaches the container, it will first hit the V-shaped protective member 6. After the V-shaped protective member 6 is hit, the angle becomes larger and deformed. Since its bottom is hinged to the protective frame 4, it will push the protective frame 4 to drive the rod-type plug-in 3 to move downward. The rod-type plug-in 3 moves downward to squeeze the elastic buffer module 5. The elastic buffer module 5 undergoes elastic deformation to absorb the impact force generated by the collision and avoid the impact force directly acting on the container, effectively protecting the container from being damaged. Through such a structural design, during the container lifting process, it can protect and buffer the impact force of the collision in advance, reduce the risk of damage to the container, and improve the safety and reliability of the lifting operation.

[0044] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in this embodiment, the V-shaped protective member 6 includes a first protective rod 61 and a second protective rod 62. The adjacent ends of the first protective rod 61 and the second protective rod 62 are hinged to each other, and the ends away from each other of the first protective rod 61 and the second protective rod 62 are hinged to the loading frame 2 and the protective frame 4 respectively. The first protective rod 61 and the second protective rod 62 form a V-shaped structure, and the angle is formed between the first protective rod 61 and the second protective rod 62.

[0045] Before lifting the container, the V-shaped guard 6 is in a retracted state. At this time, the angle between the first guard bar 61 and the second guard bar 62 is small. When the traction module 7 drives the guard frame 4 to move down and unfold the V-shaped guard 6, the first guard bar 61 and the second guard bar 62 rotate around the hinge points with the loading frame 2 and the guard frame 4 respectively, and the angle gradually increases and unfolds around the container. When hit, the impact force causes the angle between the first guard bar 61 and the second guard bar 62 to further increase. Since they are hinged to the loading frame 2 and the guard frame 4 respectively, this deformation will drive the guard frame 4 to move down, and then squeeze the elastic buffer module 5. This V-shaped structure composed of two hinged rods can flexibly adapt to the force conditions during collision, effectively transmit the collision force to the elastic buffer module 5, enhance the protection and buffering effects, and ensure the safety during container lifting.

[0046] like Figure 3 and Figure 6 As shown, in this embodiment, the rod-type plug-in 3 includes an insertion rod 31, and the four insertion rods 31 slide through the four sides of the loading frame 2 respectively, realizing a slidable connection between the protection frame 4 and the loading frame 2, and the protection frame 4 is installed at the bottom end of the four insertion rods 31, so that the protection frame 4 can stably follow the movement of the insertion rod 31, and the insertion rod 31 is provided with an end block 32 located above the elastic buffer module 5, whose function is to squeeze the elastic buffer module 5 when the insertion rod 31 moves downward, and the end block 32 is threadedly connected with a bolt 33 that is tightly pressed against the insertion rod 31. By tightening or loosening the bolt 33, the position of the end block 32 on the insertion rod 31 can be adjusted, thereby adjusting the initial compression degree of the elastic buffer module 5 to adapt to different lifting environments and protection requirements.

[0047] During the lifting process, when the V-shaped protective member 6 is hit and pushes the protective frame 4 downward, the insertion rod 31 moves accordingly, and the end block 32 squeezes the elastic buffer module 5 to achieve the buffering function. At the same time, the adjustable end block 32 improves the adaptability of the equipment, ensuring that the container can be effectively protected under various circumstances.

[0048] like Figure 6 and Figure 7 As shown, in this embodiment, the elastic buffer module 5 includes a fixed cylinder 51, and the fixed cylinders 51 are installed on all four sides of the loading frame 2. The four fixed cylinders 51 are respectively mounted on the four insertion rods 31. The fixed cylinder 51 is equipped with an elastic buffer member 52 that is slidably mounted on the insertion rod 31 and located below the end block 32. The outer periphery of the fixed cylinder 51 is equipped with a limiting member 53 for limiting the elastic buffer member 52.

[0049] The fixed cylinder 51 is installed around the loading frame 2 to provide an installation basis for the elastic buffer 52 and the limiter 53. The elastic buffer 52 is slidably sleeved on the insertion rod 31 and is located below the end block 32. When the insertion rod 31 drives the end block 32 to move downward, the end block 32 squeezes the elastic buffer 52. The elastic buffer 52 is elastically deformed under the force, absorbing the energy generated by the collision and playing a buffering role. The limiter 53 is installed on the outer periphery of the fixed cylinder 51 to limit the elastic buffer 52 to prevent the elastic buffer 52 from excessive deformation or separation from the fixed cylinder 51 during the buffering process, thereby ensuring the stable operation of the elastic buffer module 5. In actual lifting operations, this structural design enables the elastic buffer module 5 to maintain the stability of its own structure while buffering the impact force of the collision, thereby improving the buffering effect and the reliability of the equipment and effectively protecting the container from collision damage.

[0050] like Figure 7 As shown, in this embodiment, the elastic buffer 52 includes a spring 521 and a buffer disk 522. The spring 521 is installed at the top end of the fixed cylinder 51 and is sleeved on the insertion rod 31. The buffer disk 522 is installed at the top end of the spring 521 and is slidably sleeved on the insertion rod 31, and the buffer disk 522 is located below the end block 32.

[0051] When the end block 32 squeezes the buffer plate 522, the buffer plate 522 squeezes the spring 521 downward, and the spring 521 is compressed, converting the kinetic energy generated by the collision into elastic potential energy, which plays a buffering role. The buffer plate 522 is installed on the top of the spring 521 and slides onto the insertion rod 31, and is located below the end block 32. It can evenly transfer the pressure of the end block 32 to the spring 521, and at the same time ensure that the spring 521 remains stable during the compression process and will not deviate. During the lifting operation, the spring 521 and the buffer plate 522 cooperate with each other to effectively absorb the impact force of the collision, avoid damage to the container due to collision, and ensure the safe transportation of goods.

[0052] like Figure 7 and Figure 8 As shown, in this embodiment, the limiting member 53 includes a loading tube 531 and a magnetic rod 532. The loading tube 531 is installed on the outer periphery of the fixed cylinder 51. Magnetorheological fluid is provided in the loading tube 531. The bottom of the buffer tray 522 is installed with a magnetic rod 532 inserted into the loading tube 531.

[0053] When the elastic buffer 52 is squeezed and the buffer plate 522 moves downward, the magnetic rod 532 moves downward in the loading tube 531. Since the rheological properties of the magnetorheological fluid will change under the action of the magnetic field, the magnetic field change generated by the downward movement of the magnetic rod 532 causes the magnetorheological fluid to gradually harden, which limits the elastic buffer 52 and prevents excessive buffering. During the lifting process, this limiting mechanism based on magnetorheological fluid can automatically adjust the buffering force according to the size of the collision impact force, making the buffering process more stable and controllable, improving the stability and reliability of the equipment in the event of a collision, extending the service life of the equipment, and providing more reliable safety protection for container lifting operations.

[0054] like Figure 3 、 Figure 6 and Figure 7 As shown, in this embodiment, a pressure warning component 8 is installed on the buffer tray 522. When the insertion rod 31 drives the end block 32 to move downward to squeeze the buffer tray 522, an early warning can be given through the pressure warning component 8; the pressure warning component 8 includes a pressure sensor 81 and an alarm 82. The pressure sensor 81 is installed on the top of the buffer tray 522 and is located below the end block 32. The alarm 82 is installed on the side of the loading frame 2, and the pressure sensor 81 is connected to the alarm 82.

[0055] Pressure sensor 81, mounted on top of buffer tray 522 and below end block 32, precisely senses the pressure acting on buffer tray 522. When end block 32 compresses buffer tray 522 and the pressure reaches a set value, pressure sensor 81 converts the pressure signal into an electrical signal and transmits it to connected alarm 82, which is mounted on the side of loading frame 2. Upon receiving the electrical signal, alarm 82 issues an alarm signal through audible sounds, flashing lights, and other means. During lifting operations, remote operators can hear or see the alarm signal immediately, enabling them to react quickly, preventing further collisions and minimizing damage to containers, cargo, and equipment, thereby improving the safety and efficiency of port operations.

[0056] When the insertion rod 31 drives the end block 32 to move downward to squeeze the buffer plate 522, the buffer plate 522 is subjected to pressure, and the pressure sensor 81 in the pressure warning component 8 detects the pressure change on the buffer plate 522. When the pressure reaches the preset threshold, the pressure sensor 81 transmits the signal to the alarm 82. After receiving the signal, the alarm 82 issues an alarm to remind the operator that a collision has occurred. In actual operation, this early warning function can enable the operator to know the collision situation in time and take emergency measures quickly, such as stopping the lifting operation or adjusting the lifting path, etc., thereby reducing the losses caused by the collision, improving the emergency handling capabilities of port operations, and enhancing the overall safety and reliability of port container lifting operations.

[0057] like Figure 3 and Figure 10As shown, in this embodiment, the traction module 7 includes a fixed block 71, and the fixed blocks 71 are installed on both sides of the loading frame 2. A motor 73 is installed on the side of the fixed block 71, and the output end of the motor 73 is connected to the winding member 72, and the bottom end of the winding member 72 is connected to the protective frame 4.

[0058] After the motor 73 is started, its output end drives the winding member 72 to rotate, and the bottom end of the winding member 72 is connected to the protective frame 4. When the motor 73 rotates forward, the winding member 72 is wound, pulling the protective frame 4 up, so that the V-shaped protective member 6 is retracted. When the motor 73 reverses, the winding member 72 is unwound, and the protective frame 4 moves down along the container under the action of its own gravity or with the help of external force, driving the V-shaped protective member 6 to unfold. Before the lifting operation, the state of the V-shaped protective member 6 can be controlled by the motor 73. During the lifting process, the position of the protective frame 4 can also be flexibly adjusted according to actual conditions to ensure that the V-shaped protective member 6 can effectively protect the container and improve the safety and flexibility of the lifting operation.

[0059] like Figure 11 As shown, in this embodiment, the winding member 72 includes a roller 721 and a traction rope 722. The output end of the motor 73 is connected to the roller 721. The traction rope 722 is wound on the roller 721. Two openings are symmetrically opened on the loading frame 2. The bottom ends of the two traction ropes 722 pass through the two openings respectively. The bottom ends of the two traction ropes 722 are connected to elastic ropes 723. The two elastic ropes 723 are respectively connected to the two sides of the protective frame 4.

[0060] When the roller 721 rotates, the traction rope 722 is retracted and released accordingly. The opening on the loading frame 2 facilitates the passage of the traction rope 722. The bottom ends of the two traction ropes 722 are connected to the elastic rope 723, and the elastic rope 723 is then connected to the two sides of the protective frame 4. This structural design allows the traction rope 722 to smoothly drive the protective frame 4 up and down through the elastic rope 723 during the retraction and release process. The elastic rope 723 has a certain elasticity and can play a buffering role during the movement of the protective frame 4 to avoid damage to the equipment due to sudden force or movement. During the lifting operation, the motor 73 controls the rotation of the roller 721 to achieve precise control of the position of the protective frame 4, and then flexibly adjust the expansion and folding state of the V-shaped protective member 6 to effectively protect the container.

[0061] The specific working principle of the present invention is as follows:

[0062] Before the port container lifting operation begins, the crane 1 lowers the spreader 102 via the steel rope 101. At this time, the V-shaped guard 6 located between the loading frame 2 and the protective frame 4 is in a retracted position, which does not affect the spreader 102 from grabbing the container. After the grabbing is completed, according to the lifting requirements, the traction module 7 is started, and the motor 73 in the traction module 7 drives the winding member 72 to work. The roller 721 in the winding member 72 rotates, and the traction rope 722 is retracted. The traction rope 722 pulls the protective frame 4 down along the container through the elastic rope 723, so that the V-shaped guard 6 switches from the retracted first position to the extended second position. The V-shaped guard 6 is composed of a first protective rod 61 and a second protective rod 62 hinged together, and forms a protective barrier around the container when extended;

[0063] During the lifting process, if an object accidentally hits the container, it will first hit the V-shaped guard 6. After the V-shaped guard 6 is hit, the angle between the first guard bar 61 and the second guard bar 62 increases and deforms. Since they are hinged to the loading frame 2 and the guard frame 4 respectively, this deformation pushes the guard frame 4 downward, and the guard frame 4 drives the insertion rod 31 installed at its bottom end downward, and the end block 32 on the insertion rod 31 moves accordingly;

[0064] The end block 32 moves downward to squeeze the elastic buffer module 5. The spring 521 in the elastic buffer module 5 is squeezed by the buffer plate 522, causing elastic deformation, absorbing the impact force generated by the collision, preventing the impact force from directly acting on the container, and protecting the container from being damaged. At the same time, the downward movement of the buffer plate 522 drives the magnetic rod 532 to move downward in the loading tube 531. The magnetorheological fluid in the loading tube 531 gradually hardens due to the change in the magnetic field generated by the downward movement of the magnetic rod 532, which limits the elastic buffer 52, prevents excessive buffering, and ensures a stable and controllable buffering process.

[0065] In addition, when the insertion rod 31 drives the end block 32 to move downward to squeeze the buffer plate 522, the pressure sensor 81 in the pressure warning component 8 detects the pressure change on the buffer plate 522. When the pressure reaches the preset threshold, the pressure sensor 81 transmits the signal to the alarm 82. The alarm 82 sounds an alarm to remind the operator that a collision has occurred, so that the operator can take emergency measures in time to reduce the losses caused by the collision. Through the coordinated work of various components, the container lifting equipment of the present invention can effectively protect the container during the lifting process and improve the safety and reliability of the operation.

[0066] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or illustrative of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included within the scope of protection of the present invention. In addition, the appended claims are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
