Description

Technical Field

[0002] Currently, ships are equipped with various lifting devices, including those for loading and unloading cargo, lifting crew supplies, and hoisting lifeboats. Among these, the lifting devices for crew supplies are generally tower cranes mounted on the deck at the ship's side, which are driven by motors to lift supplies. These devices often use fixed or simple articulated structures, and their inherent design results in a large size when not in operation, significantly encroaching on the effective deck area. Especially for equipment with a large load on the stern frame, the external dimensions often need to be increased to meet lifting requirements, further compressing the already limited ship operating space.

[0003] Because of the non-foldable nature of fixed booms, the equipment still occupies valuable space when not in operation, forcing ships to sacrifice some cargo area. In addition, the deployment and retrieval of traditional booms mostly rely on complex manual operation or separate hydraulic systems, which increases the labor intensity and operational difficulty of the crew.

[0015] The present invention achieves the following technical effects compared to the prior art: The folding crane device for material transfer provided by this invention uses a lifting assembly mounted on a support base for lifting materials.

The storage mechanism drives a ring transmission component to rotate via a drive assembly.

After the telescopic frames are retracted into place... The insert rod, fixed on it, extends into the through hole of the fixing component. When the movable component moves in the sliding groove, it drives the rotating end to rotate and causes the pressing component to perform a radial clamping action inside the through hole, forming a preliminary lock on the insert rod.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The purpose of this invention is to provide a foldable crane arm device for material transfer, which solves the problems existing in the prior art, occupies little space, reduces labor intensity and operation difficulty, and improves the response speed and efficiency of logistical support.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 This embodiment provides a folding crane device for material transfer, such as... Figures 1-9 As shown, it includes: The support base 100 is equipped with a hoisting assembly; multiple support plates 101 are fixed circumferentially on the outer side of the support base 100; a support plate 105 is provided between two adjacent support plates 101; each support plate 101 is rotatably provided with a telescopic frame 108 at its end, and the end of the telescopic frame 108 is provided with a detachable support leg; the end of the support plate 105 is provided with a locking plate 106. The storage mechanism 200 includes a drive assembly, a ring transmission component 202, and multiple linkage components 203. The drive assembly is mounted on the support base 100. The ring transmission component 202 is coaxially rotatably mounted on the outside of the support base 100. The linkage components 203 correspond one-to-one with the telescopic frames 108. The ring transmission component 202 is connected to the corresponding telescopic frame 108 via the linkage components 203. The drive assembly drives the ring transmission component 202 to rotate, and the ring transmission component 202 drives the corresponding telescopic frame 108 to rotate via the linkage components 203, so that each telescopic frame 108 is simultaneously folded into the slot of the corresponding card plate 106 or unfolded from the slot of the corresponding card plate 106. The positioning mechanism 300, corresponding to the support plate 105, includes a fixing member 301, a movable member 302, and a pressing member 303. The support plate 105 has a slot 301a that communicates with the slot of the clamping plate 106. The top of the support plate 105 has a sliding groove communicating with the slot 301a. The movable member 302 is located within the sliding groove and the slot 301a. The fixing member 301 has a fixed end and a rotating end that are coaxially rotatably connected. The fixed end and the rotating end have internal... The cavity together forms a through hole 301d; the fixed end is fixed in the slot 301a, the movable part 302 is connected to the rotating end via a mating part, and the extrusion part 303 is set on the fixed part 301; the annular transmission part 202 drives the movable part 302 to move in the sliding groove, and this movement can drive the rotating end to rotate, and the rotation of the rotating end can drive the extrusion part 303 to perform a radial clamping action in the through hole 301d; the telescopic frame 108 is fixed with an insertion rod 301g that can extend into the through hole 301d; The auxiliary mechanism 400, which corresponds one-to-one with the positioning mechanism 300, includes a positioning member 401, a contact member 402, and an auxiliary member 403. The positioning member 401 is fixed in the through hole 301d corresponding to the fixed end, and the positioning member 401 is located at the end of the pressing member 303 away from the bearing seat 100. The positioning member 401 is provided with a plurality of elastically deformable recesses 401b in the circumferential direction. The rotating end can be connected to each recess 401b in sequence through the auxiliary member 403 and the contact member 402. The rotation of the rotating end can squeeze each recess 401b in sequence through the auxiliary member 403 and the contact member 402, so that each recess 401b retracts inward to clamp the insertion rod 301g in the inner hole of the positioning member 401.

[0023] The lifting assembly is mounted on the support base 100 for lifting materials. The support plate 101 and support plate 105 arranged circumferentially on the outer side of the support base 100 form a support frame. The telescopic frame 108 rotatably mounted at the end of each support plate 101 can be synchronously retracted or extended under the drive of the storage mechanism 200. The storage mechanism 200 drives the ring transmission component 202 to rotate through the drive component. The ring transmission component 202 transmits power to the corresponding telescopic frame 108 through each linkage component 203, so that all telescopic frames 108 simultaneously retract into the slot of the card plate 106 or extend outward, thereby significantly compressing the volume of the equipment that originally occupied a lot of space. After the telescopic frame 108 is retracted into place, the insertion rod 301g fixed on it... When the movable part 302 moves within the sliding groove, it extends into the through hole 301d of the fixing part 301, driving the rotating end to rotate and causing the pressing part 303 to perform a radial clamping action inside the through hole 301d, thus initially locking the insertion rod 301g. At the same time, the positioning part 401 fixed in the through hole 301d in the auxiliary mechanism 400 retracts inward and hugs the insertion rod 301g through its circumferentially set elastic recess 401b, driven by the auxiliary part 403 and the abutting part 402 at the rotating end, thus achieving secondary positioning and locking. The entire folding, unfolding and locking process is completed through mechanical linkage, without relying excessively on separate hydraulic systems or complex manual operations, which reduces the difficulty of operation and ensures the stability and reliability of the structure after folding.

[0024] Working principle: During use, the telescopic part 103 and the boom part 104 work together to transfer materials. Due to the large structure and the large storage space occupied by the extended parts, this device uses the ring transmission component 202 and the linkage component 203 to achieve an integrated mechanical retraction structure, which significantly compresses the volume of the equipment that originally occupied a large area. It achieves orderly folding through mechanical linkage, ensuring that the key components of the equipment are protected during storage. Since all moving parts are systematically stored and fixed, the working state can be quickly restored by reversing the operation when used again, which effectively improves the response speed of logistics. Furthermore, the auxiliary mechanism 400 and the positioning mechanism 300 achieve the initial alignment of the telescopic frame 108, reducing the difficulty and physical consumption of manual operation. The locking part 109 and the telescopic frame 108 are fixed by bolts to ensure that the device is aligned and tightly locked, forming a rigid connection that is stable, safe and reliable, and avoiding equipment damage caused by deviation.

[0025] Among them, such as Figures 1-4 As shown, the relevant settings for the support base 100 are as follows: Specifically, the main body of the device provided in this embodiment (such as the support 100, hoisting components, etc., which can be reasonably set according to actual needs) is made of high-strength gray metal.

[0026] In the optional embodiments of this example, the preferred hoisting assembly includes a rotating plate 102, a telescopic part 103, and a boom part 104; the rotating plate 102 is coaxially rotatably connected to the upper end face of the support base 100; the telescopic part 103 is disposed on the rotating plate 102 (the telescopic part 103 is located in the middle position of the rotating plate 102), and the telescopic part 103 is a frame that can be extended and folded in the vertical direction; the boom part 104 is disposed on the upper end of the telescopic part 103.

[0027] Specifically, each bearing plate 101 is evenly distributed on the circumferential outer wall of the bearing seat 100.

[0028] Specifically, the telescopic part 103 and the hoisting part (a column is fixed at the center of the rotating plate 102, and a crossbeam is rotatably connected to the column. One end of the crossbeam is connected to the rotating plate 102 through a folding frame. The upper end of the telescopic part 103 is hinged to one end of the crossbeam, and the lower end of the telescopic part 103 is hinged to the rotating plate 102; the telescopic part 103 can extend and retract on its own; a boom is provided above the crossbeam, and the hoisting end of the boom has a hoisting part. A corresponding fixed pulley is provided on the side of the crossbeam near the hoisting part; a rope retractor is provided on the rotating plate 102 near the boom 104 for retracting and releasing the hoisting rope. The hoisting rope from the retractor passes through the fixed pulley, the boom 104, and the boom and hangs down from the end of the boom. A hoisting component is provided at the end of the hoisting rope; a storage slot for holding the hoisting component is provided on the rotating plate 102 at the position corresponding to the hoisting component) work together to transfer materials.

[0029] Specifically, the rotating plate 102 is used to support the weight of the wing and provide a center of rotation.

[0030] Among them, such as Figures 1-5 As shown, here are the setup instructions for storage mechanism 200: In the optional solutions of this embodiment, a more preferred embodiment is that the annular transmission component 202 includes an annular plate 202a and an annular plate 202c; the annular plate 202a is coaxially rotatably disposed on the outer side of the support seat 100; the annular plate 202c is coaxially disposed on the outer ring of the annular plate 202a; the annular plate 202a is fixedly connected to the annular plate 202c via multiple auxiliary parts 202b; a gear ring 202d is fixedly disposed on the inner side of the annular plate 202a; the output end of the drive component meshes with the gear ring 202d for transmission; the linkage component 203 includes a rotating shaft 203a, a gear 203b, and a gear ring 203c; the telescopic frame 108 is rotatably disposed at the end of the support plate 101 via the rotating shaft 203a; a gear 203b is fixedly disposed on the rotating shaft 203a; the gear ring 203c is fixedly disposed on the outer ring of the annular plate 202c; and the gear 203b meshes with the gear ring 203c for transmission.

[0031] Specifically, a second card plate 107 is fixed to the end of the bearing plate 101, and one end of the telescopic frame 108 is rotatably connected to the slot of the second card plate 107 via a rotating shaft 203a. The rotating shaft 203a is rotatably connected to the slot of the second card plate 107 via a bearing.

[0032] Specifically, a locking part 109 is fixed on the outer wall of the second card plate 107. The locking part 109 has a locking groove, and the retracted end of the telescopic frame 108 can be fixed in the locking groove by bolts.

[0033] Specifically, due to the large size of the structure and the outward extension of the components, the storage space occupied is huge and the handling is difficult. This embodiment uses the ring transmission component 202 and the linkage component 203 to achieve an integrated mechanical shrinkage structure, which significantly compresses the volume of the equipment that originally occupied a large area, turning parts into a whole, optimizing storage efficiency, minimizing the space occupied by the equipment in the warehouse, alleviating the space pressure of limited space, avoiding the risk of component damage caused by scattered storage, and improving the safety and standardization of equipment management. At the same time, the orderly folding is achieved through mechanical linkage, ensuring that the key components of the equipment are protected during the storage process. Since all moving parts are systematically stored and fixed, they can be quickly restored to working state by reversing the operation when used next, effectively improving the response speed and operational efficiency of logistical support.

[0034] In the optional solutions of this embodiment, more preferably, the storage mechanism 200 further includes a moving unit, which includes a plurality of rollers 201d, and the rollers 201d are respectively disposed on the bottom of the support plate 101.

[0035] Specifically, the roller 201d is a universal wheel structure. After the transfer is completed, the main body of the device is moved into the warehouse by the roller 201d.

[0036] Specifically, the drive components and the moving unit together constitute the support component 201 of the storage mechanism 200.

[0037] In the optional solutions of this embodiment, the preferred drive component includes a motor 201b, a support 201a, and a gear 201c; the support 201a is fixedly disposed on the bottom side wall of the bearing seat 100, and the motor 201b is fixed on the support 201a; the output end of the motor 201b is fixed with a gear 201c that meshes with the gear ring 202d.

[0038] Specifically, the motor 201b is detachably mounted on the support 201a. The motor 201b is regulated by an external controller. In use, the motor 201b drives the gear 201c to rotate. The ring transmission component 202 and the linkage component 203 work together to realize an integrated mechanical shrink structure, which significantly compresses the volume of the equipment that originally occupied a large area. It achieves orderly folding through mechanical linkage, ensuring that the key components of the equipment are protected during storage.

[0039] Working principle: In use, the motor 201b is started via an external controller. Motor 201b drives gear 201c to rotate. Gear 201c meshes with gear ring 202d, thereby driving the annular plate 202a to rotate. Simultaneously, the rotation of annular plate 202a drives the four auxiliary parts 202b to rotate. These auxiliary parts 202b drive annular plate 202c to rotate simultaneously. Annular plate 202c drives gear ring 203c to rotate synchronously, with gear 203b meshing with gear ring 203c. The rotating shaft 203a is driven to rotate, and the rotating shaft 203a drives the telescopic frame 108 to rotate around the rotating shaft 203a. During use, the telescopic frame 108 and the support plate 101 are in the same horizontal direction. After the transfer is completed, the motor 201b drives the gear 201c to reverse, thereby causing the telescopic frame 108 to be locked in the locking part 109. In this way, the volume of the equipment that originally occupied a large area is significantly compressed. It achieves orderly folding through mechanical linkage, ensuring that the key components of the equipment are protected during the storage process.

The rod 302b is slidably disposed within the inclined groove 302a, the sliding groove, and the slot 301a. The movable cylinder 302d is located within the slot 301a and is fixed to the movable rod 302b (specifically, a stop rod 302e is fixed inside the movable cylinder 302d, and a docking cylinder extends from the fixed cylinder 301c to the inside of the rotating cylinder 303a, allowing the stop rod 302e to be located within the docking cylinder, ensuring a stable docking connection between the fixed component 301 and the movable component 302). A limiting block 302f is fixed on the outer wall of the movable cylinder 302d; the limiting block 302f is located within the arc-shaped groove 303g; the movable cylinder 302d, the limiting block 302f, and the arc-shaped groove 303g together form a mating component.

[0041] Specifically, the rotating cylinder 303a is rotatably connected to the outside of the fixed cylinder 301c. The fixed cylinder 301c has multiple sets of auxiliary ports on its outer circumference. The auxiliary ports are not shown in the figure. The circular protrusions 303b are fixedly installed in the auxiliary ports.

[0042] In a preferred embodiment, the fixing member 301 further includes an auxiliary ring 301f, which is coaxially fixed inside the fixing cylinder 301c. The extrusion member 303 includes an annular groove 303c, and the auxiliary ring 301f is provided with an annular groove 303c. Multiple through movable openings 303d are provided in the annular groove 303c, and the movable openings 303d communicate with the inner side of the fixing cylinder 301c. Each movable opening 303d is evenly distributed circumferentially around the axis of the auxiliary ring 301f. An extrusion block 303e is provided in the movable opening 303d, and a rubber ring 303f is provided in the annular groove 303c. The rubber ring 303f is fixedly connected to each extrusion block 303e. Multiple round protrusions 303b for extruding the corresponding extrusion blocks 303e are fixed on the inner wall of the rotating cylinder 303a. The round protrusions 303b correspond one-to-one with the extrusion blocks 303e. Each extrusion block 303e can perform a radial clamping action inside the fixing cylinder 301c.

[0043] In the optional solutions of this embodiment, it is more preferred that the outer wall of the fixed cylinder 301c is fixedly connected to the inner wall of the slotted 301a via multiple linkage parts 301b.

[0044] In the optional solutions of this embodiment, it is more preferred that the auxiliary ring 301f is coaxially fixed inside the fixed cylinder 301c by a plurality of fixing parts 301e.

[0045] Specifically, through its precise auxiliary mechanism 400 and positioning mechanism 300, the telescopic frame 108 is initially aligned, reducing the difficulty and physical exertion of manual operation; at the same time, its high-precision positioning mechanism 300 plays a role when approaching the final position, making fine adjustments to ensure that the device is aligned and tightly locked, forming a rigid connection that is stable and reliable.

[0046] Working principle: During use, the telescopic frame 108 rotates around the pivot 203a. At this time, the insertion rod 301g on the telescopic frame 108 corresponds to the slot 301a. When the insertion rod 301g abuts into the slot 301a, the gear 201c drives the annular plate 202a to rotate. Due to the deflection of the inclined groove 302a, the movable rod 302b moves within the sliding groove 302c. Its movable cylinder 302d drives the limiting block 302f to move linearly in the horizontal direction within the slot 301a. The corresponding sliding connection of 02f is in the arc groove 303g, thereby driving the outer rotating cylinder 303a to rotate. While the rotating cylinder 303a rotates, it drives the internal circular protrusion 303b to rotate synchronously. The circular protrusion 303b abuts against the extrusion block 303e. The rubber ring 303f limits the extrusion block 303e. The extrusion block 303e abuts against the insertion rod 301g in the movable opening 303d, thereby ensuring the stability of the insertion rod 301g. In this way, the initial alignment of the telescopic frame 108 is achieved.

[0047] Among them, such as Figures 1-4 and Figures 6-9 As shown, the relevant settings instructions for auxiliary mechanism 400 are as follows: In a preferred embodiment, the positioning member 401 includes a positioning ring 401a coaxial with both the fixed end and the rotating end; the positioning ring 401a is fixedly disposed on the fixed end, and the sidewall of the positioning ring 401a has a plurality of circumferentially distributed recesses 401b; the abutting member 402 corresponds one-to-one with the recesses 401b; the abutting member 402 includes an abutting plate 402a and an abutting portion 402b, the abutting plate 402a and the abutting portion 402b are T-shaped connected, one end of the abutting portion 402b is fixedly connected to the outer sidewall of the recess 401b, and the abutting plate 402a is fixedly disposed at the end of the abutting portion 402b away from the recess 401b; the inner sidewall of the rotating end Multiple auxiliary components 403 are fixed on the upper part, and each auxiliary component 403 corresponds to a contact component 402. Each auxiliary component 403 includes a vertical part 403a and a pressing part 403b. One end of the vertical part 403a is fixed to the inner wall of the rotating end, and the pressing part 403b is fixed to the free end of the vertical part 403a. The pressing part 403b has guide surfaces on both sides of the positioning ring 401a in the circumferential direction. When the rotating end rotates around the axis of the positioning ring 401a, the pressing part 403b can be pressed against the corresponding contact plate 402a through the corresponding guide surfaces, so that the corresponding recessed part 401b is pushed inward towards the axis of the positioning ring 401a and clamped.

[0048] Working principle: When the rotating drum 303a rotates, it drives the vertical part 403a to rotate simultaneously. When the vertical part 403a rotates, it drives the pressing part 403b to contact the contact part 402b, thereby causing the contact plate 402a to retract inward. At this time, the contact part 402b on the contact plate 402a contacts the recessed part 401b, thus causing the recessed part 401b on the positioning ring 401a to deform and further position the insertion rod 301g. Then, the locking part 109 and the telescopic frame 108 are fixed by bolts. After the two-stage positioning is completed, a gapless rigid fixation is formed, which prevents navigation swaying and deviation, ensures that the device is aligned and tightly locked, forms a rigid connection, is stable and safe and reliable, and avoids equipment damage caused by deviation.

[0049] Regarding other relevant supplementary explanations: Specifically, the integrated mechanical shrink structure is achieved by the cooperation of the ring transmission component 202 and the linkage component 203, which significantly compresses the volume of the equipment that originally occupied a large area. It achieves orderly folding through mechanical linkage. Since all moving parts are systematically stored and fixed, the space occupied is greatly reduced. When used again, it can be quickly restored to working state through reverse operation, which effectively improves the response speed and efficiency of logistics support.

[0050] Specifically, the gear 201c drives the annular plate 202a to rotate. Due to the deflection of the inclined groove 302a, the movable rod 302b moves within the sliding groove 302c. Since the limiting block 302f is correspondingly slidably connected within the arc groove 303g, the rotating cylinder 303a rotates. The rotating cylinder 303a drives its internal circular protrusion 303b to rotate synchronously, causing the pressing block 303e to abut against the insertion rod 301g within the movable opening 303d, thereby ensuring the stability of the insertion rod 301g. In this way, the initial alignment of the telescopic frame 108 is achieved.

[0051] Specifically, the vertical part 403a is rotated simultaneously by the rotating drum 303a, and its pressing part 403b comes into contact with the contacting part 402b, so that the contacting part 402b on the contact plate 402a comes into contact with the recessed part 401b. This causes the recessed part 401b on the positioning ring 401a to further position the insertion rod 301g. Then, the locking part 109 and the telescopic frame 108 are fixed by bolts to ensure that the device is aligned and tightly locked, forming a rigid connection that is stable, safe and reliable, and avoids equipment damage caused by deviation.

[0052] Specifically, the telescopic part 103 is rotatably connected to the rotating plate 102 via a hinge. The telescopic part 103 is a telescopic component, which drives the position of the boom part 104 to change through related connecting parts. The bearing seat 100 has a rotating plate 102 in the center as a pivot to support the weight of the wing and provide a center of rotation. In use, the telescopic part 103 and the boom part 104 cooperate to transfer materials, which is suitable for use in multiple scenarios.
