Description

Technical Field

[0001] This invention belongs to the field of container hoisting technology, specifically relating to a device for hoisting containers, and more particularly to a hoisting machine, a hoisting module, and a method for operating the same. Background Technology

[0002] Various lifting equipment are widely used in ports, logistics centers, and container yards to handle and stack containers. To achieve stable lifting, spreaders are usually equipped with multiple twist locks. These twist locks need to be synchronized by a synchronizing linkage to ensure that their rotation is synchronized, preventing safety accidents such as container tilting or falling off due to a single twist lock not being in place.

[0003] In related technologies, the connection between the synchronizing rod and the countershaft of the rotary lock is often achieved through key connections, pin connections, or other similar methods. When a rotary lock needs to be replaced individually due to wear, deformation, or damage, its connection to the synchronizing rod must first be disassembled. For bolt-fixed connections, multiple bolts need to be removed one by one, which is cumbersome and time-consuming. For pin or key connections, special tools are required for hammering or pressing, which affects the reliability and synchronization accuracy of subsequent connections.

[0004] Therefore, how to avoid damage to the synchronizing link and the turnlock caused by repeated disassembly is a technical problem that urgently needs to be solved.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0006] This disclosure provides at least one hoisting machine, a hoisting module, and a method for operating the same.

[0007] In a first aspect, embodiments of this disclosure provide a hoisting module, including:

[0008] support;

[0009] The support frame is slidably equipped with hoisting plates at both ends;

[0010] A driving component, which is mounted on the bracket, is used to drive the two hoisting plates to move relative to each other or away from each other;

[0011] The bottom of the hoisting plate is provided with rotatable locks at both ends;

[0012] The two rotary locks are connected by a synchronizing link;

[0013] The end of the synchronizing link is sleeved on the secondary shaft of the corresponding rotary lock and is rotatably connected to the secondary shaft of the corresponding rotary lock through a quick-release component.

[0014] When the two rotary locks rotate, the rotation of the two rotary locks is synchronized by the synchronizing linkage;

[0015] The quick-release component includes:

[0016] The pressure tube has multiple supporting members arranged along its circumference;

[0017] A lifting ring is sleeved on the pressure tube and threadedly connected to the outer wall of the pressure tube;

[0018] One end of each of the plurality of abutting members is connected to the lower part of the pressure tube, and the other end is slidably connected to the outer wall of the lifting ring;

[0019] When the end of the synchronous link is limited, the lifting ring is lowered by external force, thereby causing the abutment to abut against the top surface of the end of the synchronous link; when the turnlock needs to be replaced, the lifting ring is raised by external force, thereby releasing the abutment between the abutment and the top surface of the end of the synchronous link, and disassembly is completed.

[0020] In one alternative embodiment, the abutment includes:

[0021] A supporting arm, which is rotatably connected to the lower part of the pressure tube;

[0022] The connecting arm has one end rotatably connected to the supporting arm, and the other end slidably connected to the lifting ring via a slider;

[0023] When the lifting ring is lowered by external force, it causes the supporting arm and connecting arm to fold, so that the top surface of the supporting arm and the end of the synchronous link abuts against each other; when the lifting ring is raised by external force, it causes the supporting arm and connecting arm to flatten, so as to release the abutment between the supporting part and the top surface of the end of the synchronous link.

[0024] In one optional embodiment, the inner wall of the pressure tube is provided with internal threads;

[0025] The outer wall of the sub-shaft is provided with an external thread that is compatible with the internal thread;

[0026] The pressure tube is connected to the secondary shaft via internal and external threads.

[0027] In one optional embodiment, the pressure tube includes:

[0028] Pressure tube body;

[0029] Multiple pressure blocks are disposed below the pressure tube body and are inserted into the slots of the pressure tube body via connecting rods;

[0030] A return spring is provided between the connecting rod and the slot.

[0031] In one alternative embodiment, a rotary bearing is embedded at the end of the synchronizing link;

[0032] The inner sleeve of the rotating bearing is fitted onto the secondary shaft.

[0033] In one alternative embodiment, a support platform extends radially outward from the location where the secondary shaft is opposite to the inner sleeve of the rotary bearing;

[0034] The top surface of the support platform is lower than the top surface of the rotating bearing to form an annular groove for placing the pressure block.

[0035] In one optional embodiment, the two ends of the pressure block are inclined surfaces;

[0036] Furthermore, the outer wall of the pressure block abuts against the inner sleeve of the rotating bearing;

[0037] When the secondary shaft rotates, it drives the pressure block to rotate, so that the inner wall of the inner sleeve of the rotating bearing is cleaned through the two ends of the pressure block.

[0038] In one alternative embodiment, the height of the top surface of the pressure block is higher than the height of the top surface of the rotary bearing;

[0039] Furthermore, the side wall at the end of the synchronous connecting rod is provided with a chip removal hole, which is connected to the space where the top surface of the rotating bearing is located.

[0040] Secondly, this disclosure also provides a hoisting machine, comprising:

[0041] The hoist body;

[0042] Such as the hoisting module mentioned above;

[0043] The hoisting module is mounted on the hoisting machine.

[0044] Thirdly, this disclosure also provides a working method using the hoisting module as described above, the working method comprising:

[0045] When it is necessary to fix the synchronizing link, the working method includes:

[0046] The end of the synchronizing link is sleeved onto the secondary shaft of the corresponding rotary lock;

[0047] Rotate the pressure tube to connect it to the secondary shaft;

[0048] The lifting ring is lowered by rotating it with external force, thereby causing the top surface of the supporting part to abut against the end of the synchronous connecting rod;

[0049] When it is necessary to release the fixing of the synchronizing link, the working method includes:

[0050] The lifting ring is raised by rotating it with external force, releasing the top surface of the supporting part from the end of the synchronous connecting rod;

[0051] Rotate the pressure tube to disconnect it from the secondary shaft;

[0052] Separate the end of the synchronizing link from the secondary shaft of the rotary lock and replace the rotary lock.

[0053] The beneficial effects of this invention are that, through the cooperation of the pressure pipe, lifting ring and supporting parts, when replacing the twist lock, only the lifting ring needs to be rotated to release the support, without the need to disassemble the bolts or knock the pin, which greatly simplifies the operation steps, saves maintenance time, and fundamentally avoids the physical damage to the synchronous connecting rod and twist lock sub-shaft caused by repeated disassembly and assembly. It changes the traditional fixed connection method and realizes the rapid connection and separation between the synchronous connecting rod and the twist lock sub-shaft.

Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0067] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list.

[0070] Research has revealed that the synchronous connecting rod and the rotary lock sub-shaft are often connected by key or pin. When a rotary lock needs to be replaced due to wear, deformation, or damage, its connection to the synchronous connecting rod must be disassembled first. For bolt-fixed connections, multiple bolts need to be removed one by one, which is cumbersome and time-consuming. For pin or key connections, special tools are required for hammering or pressing, which affects the reliability and synchronization accuracy of subsequent connections.

[0071] Based on the above research, the present disclosure provides a hoisting machine, hoisting module and its working method. Through the cooperation of the pressure pipe 212a, lifting ring 212b and holding member 212c, when replacing the twist lock 210, only the lifting ring 212b needs to be rotated to release the holding, without disassembling bolts or knocking pins, which greatly simplifies the operation steps, saves maintenance time, and fundamentally avoids the physical damage caused to the synchronous connecting rod 220 and the twist lock 210 sub-shaft 211 by repeated disassembly and assembly. It changes the traditional fixed connection method and realizes the rapid connection and separation between the synchronous connecting rod 220 and the twist lock 210 sub-shaft 211.

[0072] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0073] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0074] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0075] Please see Figures 1-3At least one embodiment provides a hoisting module, including: a bracket 100; hoisting plates 200 slidably disposed at both ends of the bracket 100; a driving member 300 disposed on the bracket 100 and used to drive the two hoisting plates 200 to move relative to or away from each other; wherein, the bottom ends of the hoisting plates 200 are respectively rotatably disposed with turnlocks 210; the two turnlocks 210 are connected by a synchronous connecting rod 220; the end of the synchronous connecting rod 220 is sleeved on the sub-shaft 211 of the corresponding turnlock 210, and is rotatably connected to the sub-shaft 211 of the corresponding turnlock 210 by a quick-release member 212; when the two turnlocks 210 rotate, the rotation of the two turnlocks 210 is synchronized by the synchronous connecting rod 220; the quick-release member 300 is used to drive the two hoisting plates 200 to move relative to or away from each other; wherein, the bottom ends of the two turnlocks 210 are respectively rotatably disposed with turnlocks 210; ... Component 212 includes: a pressure tube 212a, which has a plurality of abutment members 212c arranged circumferentially; a lifting ring 212b, which is sleeved on the pressure tube 212a and threadedly connected to the outer wall of the pressure tube 212a; one end of the plurality of abutment members 212c is connected to the lower part of the pressure tube 212a, and the other end is slidably connected to the outer wall of the lifting ring 212b; when the end of the synchronous connecting rod 220 is limited, the lifting ring 212b is rotated by external force to descend, thereby causing the abutment members 212c to abut against the top surface of the end of the synchronous connecting rod 220; when the rotary lock 210 needs to be replaced, the lifting ring 212b is rotated by external force to rise, thereby releasing the abutment members 212c from the top surface of the end of the synchronous connecting rod 220, and completing the disassembly.

[0076] With the cooperation of the pressure tube 212a, the lifting ring 212b and the holding part 212c, when replacing the rotary lock 210, only the lifting ring 212b needs to be rotated to release the holding, without the need to remove the bolts or knock the pin. This greatly simplifies the operation steps, saves maintenance time, and fundamentally avoids the physical damage to the synchronous connecting rod 220 and the rotary lock 210 sub-shaft 211 caused by repeated disassembly and assembly. It changes the traditional fixed connection method and realizes the quick connection and separation between the synchronous connecting rod 220 and the rotary lock 210 sub-shaft 211.

[0077] Please see Figure 3 and Figure 4 The supporting member 212c includes: a supporting arm 212c1, which is rotatably connected to the lower part of the pressure tube 212a; a connecting arm 212c2, one end of which is rotatably connected to the supporting arm 212c1, and the other end is slidably connected to the lifting ring 212b through a slider 212c3; when the lifting ring 212b is rotated downward by external force, the supporting arm 212c1 and the connecting arm 212c2 are folded, so that the supporting arm 212c1 abuts against the top surface of the end of the synchronous connecting rod 220; when the lifting ring 212b is rotated upward by external force, the supporting arm 212c1 and the connecting arm 212c2 are flattened, so as to release the abutment between the supporting member 212c and the top surface of the end of the synchronous connecting rod 220.

[0078] The lifting and lowering movement of the lifting ring 212b precisely controls the folding and flattening of the supporting arm 212c1, ensuring the uniform application and complete release of the supporting force, making the quick-release operation more stable and convenient. At the same time, the supporting arm 212c1 limits the axial movement of the synchronous connecting rod 220.

[0079] It should be noted that when the supporting arm 212c1 and the connecting arm 212c2 are supported, the end of the synchronous link 220 can pass through the supporting member 212c to complete the separation of the rotary lock 210 and the synchronous link 220.

[0080] Please see Figure 3 and Figure 4 The inner wall of the pressure tube 212a is provided with an internal thread; the outer wall of the secondary shaft 211 is provided with an external thread that matches the internal thread; the pressure tube 212a and the secondary shaft 211 are connected by the internal thread and the external thread.

[0081] The initial locking or separation of the pressure tube 212a from the secondary shaft 211 can be achieved by rotating the pressure tube 212a, providing a stable foundation for the subsequent pressing operation of the holding member 212c.

[0082] Please continue reading. Figure 3 and Figure 4 The pressure tube 212a includes: a pressure tube body 212a1; a plurality of pressure blocks 212a2, which are disposed below the pressure tube body 212a1 and are inserted into the slot of the pressure tube body 212a1 via a connecting rod 212a3; wherein a return spring 212a4 is provided between the connecting rod 212a3 and the slot.

[0083] The pressure block 212a2 can automatically maintain or return to its position under the action of the return spring 212a4, which helps to quickly disengage when unlocking and improves the efficiency of replacing the rotary lock 210.

[0084] The synchronous connecting rod 220 has a rotary bearing embedded at its end; the inner sleeve of the rotary bearing is fitted onto the secondary shaft 211. A support platform 211a extends radially outward from the point opposite the inner sleeve of the rotary bearing on the secondary shaft 211; the top surface of the support platform 211a is lower than the top surface of the rotary bearing, forming an annular groove for placing the pressure block 212a2. This annular groove structure ensures that the pressure block 212a2 is fixed in position during operation and will not experience radial movement.

[0085] Please see Figure 3 and Figure 4The pressure block 212a2 has inclined surfaces at both ends; and the outer wall of the pressure block 212a2 abuts against the inner sleeve of the rotating bearing. When the secondary shaft 211 rotates, it drives the pressure block 212a2 to rotate, thereby cleaning the inner wall of the inner sleeve of the rotating bearing through the two ends of the pressure block 212a2. When the secondary shaft 211 drives the pressure block 212a2 to rotate, its inclined surfaces can scrape away dirt or rust that may accumulate on the inner wall of the inner sleeve of the rotating bearing, preventing impurities from affecting the rotational flexibility and further ensuring the reliability of long-term operation.

[0086] Please continue reading. Figure 3 and Figure 4 The height of the top surface of the pressure block 212a2 is higher than the height of the top surface of the rotating bearing; and the side wall of the end of the synchronous connecting rod 220 is provided with a chip removal hole 221, which is connected to the space where the top surface of the rotating bearing is located.

[0087] The top surface of the pressure block 212a2 is higher than the top surface of the rotating bearing, and the end side wall of the synchronous connecting rod 220 has a chip discharge hole 221. The scraped chips can pass through the space between the top surface of the pressure block 212a2 and the top surface of the bearing, and finally be discharged through the chip discharge hole 221, thus avoiding the accumulation of impurities in the critical connection parts.

[0088] At least one embodiment also provides a hoisting machine, including: a hoisting machine body; a hoisting module as described above; the hoisting module being disposed on the hoisting machine.

[0089] This disclosure also provides a working method using the hoisting module as described above. Through the cooperation of the pressure tube 212a, the lifting ring 212b, and the supporting member 212c, when replacing the rotary lock 210, only the lifting ring 212b needs to be rotated to release the support, without the need to disassemble the bolts or knock the pin. This greatly simplifies the operation steps, saves maintenance time, and fundamentally avoids the physical damage caused to the synchronous connecting rod 220 and the rotary lock 210 sub-shaft 211 by repeated disassembly and assembly. It changes the traditional fixed connection method and realizes the rapid connection and separation between the synchronous connecting rod 220 and the rotary lock 210 sub-shaft 211.

[0090] Specifically, the working method includes:

[0091] When it is necessary to fix the synchronizing link 220, please refer to Figure 5 The working method includes:

[0092] S110: The end of the synchronizing link 220 is sleeved on the secondary shaft 211 of the corresponding rotary lock 210;

[0093] S120: Rotate the pressure tube 212a to connect the pressure tube 212a with the secondary shaft 211;

[0094] S130: The lifting ring 212b is rotated by external force to descend, thereby causing the supporting member 212c to abut against the top surface of the end of the synchronous connecting rod 220;

[0095] When it is necessary to release the fixing of the synchronizing link 220, please refer to Figure 6 The working method includes:

[0096] S210: The lifting ring 212b is raised by rotating it with external force, releasing the abutment between the holding member 212c and the top surface of the end of the synchronous connecting rod 220;

[0097] S220: Rotate the pressure tube 212a to disconnect the pressure tube 212a from the secondary shaft 211;

[0098] S230: Separate the end of the synchronizing link 220 from the secondary shaft 211 of the rotary lock 210 and replace the rotary lock 210.

[0099] In summary, this invention provides a hoisting machine, hoisting module, and its operating method. Through the cooperation of the pressure pipe 212a, lifting ring 212b, and supporting member 212c, when replacing the twist lock 210, only rotating the lifting ring 212b is needed to release the support, eliminating the need to disassemble bolts or strike the pin. This greatly simplifies the operation, saves maintenance time, and fundamentally avoids physical damage to the synchronous connecting rod 220 and the twist lock 210 sub-shaft 211 caused by repeated disassembly and assembly. It changes the traditional fixed connection method, achieving rapid connection and separation between the synchronous connecting rod 220 and the twist lock 210 sub-shaft 211. In the description of the embodiments of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0100] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0101] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0102] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0103] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
