Description

Technical Field

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

[0002] Lifting and hoisting equipment is an electromechanical device used to transport or move heavy objects. It is widely used in many fields such as construction, port loading and unloading, factory handling, logistics warehousing, etc. The lifting equipment in port loading and unloading operations efficiently completes the loading and unloading operations of containers and other goods through powerful lifting mechanisms and moving mechanisms. Port lifting and hoisting equipment is an indispensable and important tool in port loading and unloading operations. It has various types and characteristics, and is suitable for different goods and operating environments. The remote control system of port container cranes usually includes key components such as crane body, wire rope, pulley block, hook, motor, and electrical or hydraulic control system. These components work together to realize the lifting, translation, rotation and other functions of goods. They are widely used in various ports and terminals, including coastal ports, inland ports and container terminals. When selecting port lifting and hoisting equipment, it is necessary to comprehensively consider factors such as the type, weight, size and operating environment of the goods.

[0003] When the lifting equipment of the port is in use, the container is lifted and transported. After arriving at the destination, the container needs to be stacked in an orderly manner. When it needs to be lowered vertically to complete the movement, the shaking amplitude of the lifted container should not be too large, otherwise it is difficult to place the container in the specified position. If the shaking amplitude is naturally reduced, the time to complete the handling of a container will increase, which may affect the efficiency of equipment handling. Therefore, in this process, it is necessary to try to ensure the stability of the lifted container. 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 heavy object. If it encounters the influence of external factors such as wind, it is difficult to ensure the stability of the heavy object when lifting it by hanging the hook alone; because the lifting ring is generally a ring structure, during the process of lifting and moving the heavy object, it may produce a certain rotation or swing at the connection with the hook, and the deflection of the lifting ring will cause the lifted heavy object to rotate, which is not conducive to the accuracy of the placement of the heavy object. The swing of the heavy object is also prone to the danger of center of gravity shift, and remote control is generally difficult to detect dangerous factors in time and deal with them in time, which is prone to accidents.

[0034] The second sliding sleeve 85 drives the limit assembly 88 to move downward, and the lifting ring at the connection between the weight and the hook 4 is restricted from both sides, thereby reducing the shaking of the weight during the lifting and moving process, so as to facilitate the stacking of the weight.

[0035] like Figure 1-Figure 3As shown, two opposite sides of the lower end of the connecting frame 1 are provided with slide grooves 11, and the slide grooves 11 are slidably connected to the counterweight block 64.

A second fixed seat 22 is fixedly connected to the bottom of the support seat 2, 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, and the bottom of one of the teeth of the first fixed tooth 52 is extended, and the lower end is a pointed end, and the first fixed tooth 52 cooperates with the first clamping groove 31.

[0036] In this embodiment, when the hook 4 is not loaded, the bottom of the counterweight block 64 is in contact with the top of the support seat 2. Under the pulling of the first steel 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 drive 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 a suitable position, the drive 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, at this time, only the extended tip of the first fixed tooth 52 overlaps with the first slot 31, and the tooth width at the tip of the first fixed tooth 52 becomes narrower, 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 fixing 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, the end of the wire rope away from the counterweight block 64 is fixedly connected to the adjusting plate 61, a pulley 62 is arranged 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, 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, 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 is completely separated from the third fixed tooth 72.

[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 block 64 to slide upward in the slide groove 11. When the adjustment plate 61 contacts the support seat 2, the counterweight block 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 teeth of the second fixed tooth 71 cooperate with the third fixed tooth 72 to guide, 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 slot 32, the lower end of the first sliding sleeve 81 is provided with an annular limiting groove 811, 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, 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 fixing block 84, the two ends of the fixing block 84 are respectively rotatably connected to a transmission wheel 86, the two ends of the transmission wheel 86 are meshed with the tooth plates 82, and the transmission wheel 86 is fixedly connected A second steel wire rope 87 is connected, 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] In this embodiment, when the movable rod 3 rotates, it drives the first sliding sleeve 81 to rotate, so that the first sliding sleeve 81 and the hook 4 rotate synchronously, so the two tooth plates 82 and the hook 4 always keep rotating synchronously, when the movable rod 3 moves downward, the first sliding sleeve 81 slides on the second clamping groove 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, and the connecting rod 83 cannot rotate after the movable rod 3 is restricted from rotating, so it is connected to the connecting rod 8 The second sliding sleeve 85 which is engaged with the connecting rod 83 is also unable to rotate, and when the second sliding sleeve 85 slides on the connecting rod 83, its upper end always keeps the engagement with the connecting rod 83. When the weight is moved to the designated place 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 block 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 tooth 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 Fig. 9 As shown, when the heavy object lifting ring is hung on the hook 4, if it is against 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 is 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, reduce the rotation amplitude of the heavy object lifting ring, and thus reduce the shaking of the heavy object during the lifting and moving process.

[0042] Working principle: When in use, the direction of the hook 4 is adjusted according to the position of the heavy object before lifting. When adjusting, the drive motor is started so that the connecting sleeve 51 drives the movable rod 3 to rotate. After adjusting to a suitable angle, the drive motor is turned off to connect the hook 4 with the lifting ring of the heavy object. When the lifting ring abuts against the second limit plate 882, the second limit plate 882 is pushed to tilt and rotate. When the lifting ring is at the lowest point of the hook 4, it is separated from the second limit plate 882, and the second limit plate 882 is reset. After the hook 4 lifts the heavy object, the hook 4 and The movable rod 3 moves downward, at which time the first slot 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 seat 2, the first slot 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, so that the transmission wheel 86 rotates and releases the wound second steel 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 above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
