Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, in particular to a lifting equipment for heavy lifting and movement. Background Art

[0002] Hoisting equipment is electromechanical equipment used to transport or move heavy objects. It is widely used in various fields, including construction, port loading and unloading, factory handling, logistics and warehousing. Port lifting equipment utilizes powerful lifting and moving mechanisms to efficiently complete the loading and unloading of containers and other cargo. Port lifting equipment is an indispensable and important tool in port loading and unloading operations. It comes in a variety of types, each with its own unique characteristics, suitable for different cargoes and operating environments. A port container crane remote control system typically includes key components such as the crane body, wire rope, pulley block, hook, motor, and electrical or hydraulic control system. These components work together to achieve various functions such as lifting, translation, and rotation of cargo. It is widely used in various ports and terminals, including coastal ports, inland ports, and container terminals. When selecting port lifting equipment, it is necessary to consider factors such as cargo type, weight, size, and operating environment.

[0003] When the port's lifting equipment is in use, containers are lifted and moved. After arriving at the destination, the containers need to be stacked in an orderly manner. When the container needs to be lowered vertically after the move is completed, the swing amplitude of the lifted container should not be too large, otherwise it will be difficult to place the container in the specified position. If the swing amplitude is allowed to decrease naturally, the time to complete the handling of a container will increase, which may affect the efficiency of the equipment handling. Therefore, during this process, it is necessary to ensure the stability of the lifted and loaded container as much as possible. In the actual remote lifting and moving process of the port container crane remote control system, the hook of the lifting equipment is connected to the lifting ring of the load. If it encounters external factors such as wind, it is difficult to ensure the stability of the load during lifting by simply hanging the hook. Since the lifting ring is generally a ring structure, the connection between the lifting ring and the hook may produce a certain amount of rotation or swing during the movement of the load after lifting. The deflection of the lifting ring will cause the lifted load to rotate, which is not conducive to the accurate placement of the load. The swing of the load also easily causes the risk of center of gravity shift. In addition, remote control generally cannot detect dangerous factors in time and deal with them in a timely manner, which is prone to accidents.

[0004] Therefore, the present invention provides a heavy-duty lifting and moving lifting equipment that is more suitable for a remote control system of a port container crane to compensate for the defect that it is difficult to timely discover dangerous factors during remote control.

[0016] Beneficial effects of the present invention:

[0017] (1) The present invention relates to a lifting device for heavy lifting and movement.

The top of the counterweight block 64 is fixedly connected to a first steel wire rope 63 An auxiliary mechanism 8 is provided at the upper end of the hook 4, which includes a connecting rod 83 fixedly connected to the upper end of the hook 4, and a second sliding sleeve 85 slidingly engaged with the connecting rod 83, and a limiting component 88 is provided at the bottom of the second sliding sleeve 85; a driving mechanism 5 is equipped to drive the hook 4 to rotate and adjust the direction of the hook; an adjusting mechanism 6 is equipped to cooperate with the fixing mechanism 7 to fix the hook 4 when the hook 4 hangs a weight; an auxiliary mechanism 8 is equipped to limit the connection between the weight and the hook 4 after the hook 4 hangs the weight, so as to reduce shaking during movement.

[0034] When the lifting rod 3 is lifted up, the lifting hook 4 is lifted up and the lifting device 5 is in a state of being lifted and lowered, thereby the lifting device 5 is in a state of being lifted and lowered, and the lifting device 5 is in a state of being lifted and lowered, thereby the lifting device 5 is in a state of being lifted and lowered, thereby the lifting device 5 is in a state of being lifted and lowered,

[0035] like Figure 1-Figure 3As shown, slide grooves 11 are provided on both sides of the opposite lower end of the connecting frame 1, and the slide grooves 11 are slidably connected to the counterweight block 64. The top of the support seat 2 is fixedly connected to the first fixed seat 21, and a driving motor is installed on the top of the first fixed seat 21. A group of guide rods 23 are fixedly connected to the top of the support seat 2, and the guide rods 23 are respectively located on both sides of the first fixed seat 21. The bottom of the support seat 2 is fixedly connected to the second fixed seat 22, and a through groove 24 is provided at the center of the support seat 2, and the through groove 24 cooperates with the movable rod 3; a first clamping groove 31 is provided at the top of the movable rod 3, and a second clamping groove 32 is provided at the lower end of the movable rod 3; the driving mechanism 5 includes a connecting sleeve 51 rotatably connected to the top of the first fixed seat 21, and a first fixed tooth 52 is fixedly connected to the inner wall of the connecting sleeve 51. The bottom of one of the teeth of the first fixed tooth 52 is extended, and the lower end is a pointed end. The first fixed tooth 52 cooperates with the first clamping groove 31.

[0036] When the lifting lever 4 is unloaded, the bottom of the counterweight 64 is in contact with the top of the support seat 2. Under the pull of the first wire rope 63, the first slot 31 at the upper end of the movable rod 3 is engaged with the first fixed tooth 52 in the connecting sleeve 51. When the driving motor is remotely started, the connecting sleeve 51 can drive the movable rod 3 to rotate, and the direction of the hook 4 is adjusted so that the hook 4 can lift the heavy object. After adjusting to the appropriate position, the driving motor is turned off. When the hook 4 carries the heavy object and lifts it, the movable rod 3 moves downward due to gravity and slides in the through slot 24. During this process, the guide rod 23 can maintain the stability of the movement of the adjustment plate 61. When the movable rod 3 cannot move further downward, only the extended tip of the first fixed tooth 52 overlaps with the first slot 31. The tooth width at the tip of the first fixed tooth 52 is narrowed, so that the movable rod 3 has a certain rotation space to facilitate the engagement of the second fixed tooth 71 and the third fixed tooth 72.

[0037] like Figure 2-Figure 5 As shown, the adjusting mechanism 6 also includes an adjusting plate 61 located at the bottom of the fixed plate 33, the adjusting plate 61 is movably connected to the movable rod 3, the guide rod 23 passes through the adjusting plate 61 and is slidably connected to the adjusting plate 61, one end of the wire rope away from the counterweight block 64 is fixedly connected to the adjusting plate 61, a pulley 62 is provided on the top of the counterweight block 64, the pulley 62 is fixedly connected to the connecting frame 1, and the first wire rope 63 cooperates with the pulley 62; the weight of the counterweight block 64 is greater than the weight of the movable rod 3 and the hook 4; the fixing mechanism 7 includes a second fixed tooth 71 fixedly connected to the outer wall of the movable rod 3, and a third fixed tooth 72 is fixedly connected to the inner wall of the through groove 24, the third fixed tooth 72 cooperates with the second fixed tooth 71, the top of the third fixed tooth 72 is a pointed end, and the bottom of one of the teeth of the second fixed tooth 71 is extended, and the lower end is a pointed end; when the bottom of the counterweight block 64 contacts the support seat 2, the second fixed tooth 71 and the third fixed tooth 72 are completely separated.

[0038] In this embodiment, when the movable rod 3 moves downward, the fixed plate 33 pulls the adjustment plate 61 downward, and at the same time pulls the first steel wire rope 63, so that the first steel wire rope 63 pulls the counterweight 64 to slide upward in the slide groove 11. When the adjustment plate 61 contacts the support seat 2, the counterweight 64 stops sliding, and the second fixed tooth 71 on the movable rod 3 moves downward to approach the third fixed tooth 72. The tip tooth of the second fixed tooth 71 cooperates with the third fixed tooth 72 to play a guiding role, so that the second fixed tooth 71 It engages with the third fixed tooth 72, so that the hook 4 cannot rotate after loading, thereby enhancing the stability of the lifting equipment. When the hook 4 is separated from the weight, the counterweight block 64 moves downward due to its own weight, pulling the first steel wire rope 63, so that the adjustment plate 61 drives the movable rod 3 and the hook 4 to move upward, and the tip of the first fixed tooth 52 is always located in the first slot 31. Therefore, when the movable rod 3 moves upward, it can guide the movable rod 3 to adjust its direction, so that the first slot 31 is completely re-engaged with the first fixed tooth 52.

[0039] like Figure 5-Figure 9 As shown, the auxiliary mechanism 8 also includes a first sliding sleeve 81 located at the top of the hook 4, the inner wall of the first sliding sleeve 81 cooperates with the second card groove 32, and an annular limiting groove 811 is opened at the lower end of the first sliding sleeve 81, and the limiting groove 811 cooperates with the bottom plate of the second fixed seat 22. A group of tooth plates 82 are fixedly connected to the bottom of the first sliding sleeve 81, and the tooth plates 82 slide through the top of the hook 4. The upper end of the connecting rod 83 is fixedly connected to a fixed block 84, and the two ends of the fixed block 84 are respectively rotatably connected to a transmission wheel 86, and the two ends of the transmission wheel 86 are meshed with the tooth plate 82. The transmission wheel 86 is fixedly connected It is connected to a second steel wire rope 87, and one end of the second steel wire rope 87 away from the transmission wheel 86 is fixedly connected to the lower end of the second sliding sleeve 85; the limiting assembly 88 includes a first limiting plate 881 and a second limiting plate 882, the first limiting plate 881 is fixedly connected to the bottom of the second sliding sleeve 85, and a rotating groove 883 is provided at the bottom of the second sliding sleeve 85 near the opening direction of the hook 4, and a fixed shaft 884 is fixedly connected in the rotating groove 883, and the fixed shaft 884 is rotatably connected to the top of the second limiting plate 882, and the lower end of the rotating groove 883 is inclined near the first limiting plate 881.

[0040] When the movable rod 3 is rotated, the first sliding sleeve 81 is driven to rotate, so that the first sliding sleeve 81 and the hook 4 rotate synchronously. Therefore, the two tooth plates 82 and the hook 4 always rotate synchronously. When the movable rod 3 moves downward, the first sliding sleeve 81 slides on the second slot 32, so that the transmission wheel 86 moves to the lower end of the tooth plate 82. During this process, the transmission wheel 86 rotates, so that the second steel wire rope 87 wound on the transmission wheel 86 is released, and the second sliding sleeve 85 drives the limiting assembly 88 to slide downward on the connecting rod 83. The first limiting plate 881 and the second limiting plate 882 are respectively located on both sides of the heavy object lifting ring. The second sliding sleeve 85 is slidably engaged with the connecting rod 83. After the movable rod 3 is restricted from rotating, the connecting rod 83 cannot rotate. The second sliding sleeve 85 engaged with the second sliding sleeve 85 is also unable to rotate, and when the second sliding sleeve 85 slides on the connecting rod 83, its upper end always remains engaged with the connecting rod 83. When the weight is moved to the designated location and put down, the sling between the hook 4 and the weight is bent, and the load of the hook 4 disappears, causing the counterweight 64 to slide down, pulling the first steel wire rope 63, so that the other end of the first steel wire rope 63 pulls the adjustment plate 61, driving the fixed plate 33 together with the movable rod 3 and the hook 4 to move upward. When the hook 4 moves upward, the teeth of the transmission wheel 86 move on the toothed plate 82, causing the transmission wheel 86 to reel in the second steel wire rope 87 again, pulling the second sliding sleeve 85 to drive the limit assembly 88 to move upward, releasing the restriction on the weight ring, separating the weight from the hook 4, and completing the movement of the weight.

[0041] In this embodiment, if Figure 8 and Figure 9 As shown, when the heavy object lifting ring is hung on the hook 4, if it is in conflict with the second limit plate 882, the second limit plate 882 will rotate toward the first limit plate 881 with the fixed axis 884 as the center. When the heavy object lifting ring reaches the lowest point of the hook 4, it separates from the second limit plate 882, and the second limit plate 882 automatically resets and becomes parallel to the first limit plate 881. The side of the rotating groove 883 close to the first limit plate 881 is inclined, so that the second limit plate 882 can only flip toward the side close to the first limit plate 881. When the two are parallel, the second limit plate 882 cannot flip toward the side away from the first limit plate 881. When the second sliding sleeve 85 drives the limit assembly 88 to move downward, the first limit plate 881 and the second limit plate 882 limit the moving range of the heavy object lifting ring, reducing the rotation amplitude of the heavy object lifting ring, thereby reducing the shaking of the heavy object during the lifting and movement process.

[0042] Working principle: When in use, adjust the direction of the hook 4 according to the position of the weight before lifting, start the drive motor during adjustment, so that the connecting sleeve 51 drives the movable rod 3 to rotate, and after adjusting to a suitable angle, turn off the drive motor, so that the hook 4 is connected to the lifting ring of the weight, and when the lifting ring abuts against the second limit plate 882, the second limit plate 882 is pushed to tilt and rotate, and when the lifting ring is at the lowest point of the hook 4, it separates from the second limit plate 882, and the second limit plate 882 is reset. After the hook 4 lifts the weight, pull the hook 4 and When the movable rod 3 moves downward, the first latch groove 31 and the first fixed tooth 52 begin to separate, and the second fixed tooth 71 and the third fixed tooth 72 begin to approach each other. When the adjustment plate 61 abuts against the top of the support base 2, the first latch groove 31 and the first fixed tooth 52 only overlap at the extended tip, so that the movable rod 3 has a certain rotation space to facilitate the engagement of the second fixed tooth 71 and the third fixed tooth 72. After the second fixed tooth 71 and the third fixed tooth 72 are engaged, the movable rod 3 is restricted and cannot rotate.

[0043] During the rotation of the movable rod 3, the first sliding sleeve 81 drives the two tooth plates 82 to rotate synchronously. When the movable rod 3 moves downward, the first sliding sleeve 81 slides on the second slot 32, and the height remains unchanged. The tooth plate 82 slides on the hook 4, and the transmission wheel 86 on the connecting rod 83 approaches the lower end of the tooth plate 82, causing the transmission wheel 86 to rotate and release the wound second wire rope 87, so that the second sliding sleeve 85 slides downward on the connecting rod 83 and drives the limit assembly 88 to move downward, so that the first limit plate 881 and the second limit plate 882 limit the heavy object lifting ring from both sides. When the equipment lifts and moves the heavy object, the rotation range of the lifting ring is limited, thereby reducing the shaking of the heavy object.

[0044] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
