Description

Technical Field

[0001] This invention belongs to the field of sling manufacturing technology, and particularly relates to an adaptive undamped overturning device. Background Technology

[0002] Currently, for large finished products (such as extra-long rod-shaped components), lifting and turning operations typically require pre-designed dedicated lifting positions on the finished product and manual installation of lifting equipment. After lifting, the lifting equipment still needs to be unloaded manually. This traditional operating mode has significant drawbacks: firstly, frequent manual intervention leads to low work efficiency and increases labor costs and operational risks; secondly, the lifting equipment lacks adaptability, and when dealing with finished products of different sizes or center of gravity distributions, the inertia of the finished product during turning can easily cause jamming, swaying, or imbalance, resulting in damage to the finished product or the lifting equipment.

[0003] Given that existing lifting devices suffer from problems such as reliance on manual labor and poor adaptability, there is an urgent need for an adaptive undamped overturning device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive undamped flipping device to solve the above-mentioned problems.

[0014] Optionally, the fixed ends of the motor, the reducer, and the electromagnetic clutch are all fixed to the hanger by high-strength bolts.

Detailed Implementation

[0017] 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.

[0018] 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.

[0019] Reference Figures 1 to 3 This invention discloses an adaptive undamped flipping device, comprising: Clamping base 9; Hanger 4 is rotatably engaged with clamping base 9; The fixed end of the cable chain double compensation mechanism is connected to the hanger 4, and the movable end of the cable chain double compensation mechanism is connected to the edge of the clamping base 9. Dual compensation mechanisms for cable chains include: The end of the cable chain 5 is connected to the edge of the corresponding clamping base 9 via a buffer compensator 11; The sprocket 3 rotates with the hanger 4, and the sprocket 3 meshes with the middle of the drag chain 5, with the middle of the drag chain 5 wrapped around the upper part of the sprocket 3; The drive unit has its fixed end fixedly connected to the hanger 4, and the output shaft of the drive unit is connected to the sprocket 3 through a clutch structure.

[0020] In use, the operator provides initial power through the drive unit. When the device is unloaded, the clutch mechanism is closed, and the output shaft of the drive unit transmits power to the sprocket 3, causing it to rotate as the driving wheel. The sprocket 3 drives the moving cable chain 5, which is engaged with it. The cable chain 5 transmits traction force to the edge of the clamping base 9 through the buffer compensators 11 connected to its two ends. Since the clamping base 9 is rotatably engaged with the lifting frame 4 through the intermediate rotating shaft, under the traction of the cable chain 5, the clamping base 9 can be actively driven to rotate approximately 90 degrees, completing the preparatory posture adjustment of the lifting device.

[0021] Once the clamping base 9 holds a large rod-shaped object, the device enters the load-bearing working state. At this time, the clutch mechanism switches to the disengaged state, and the sprocket 3 disengages from the power output of the drive unit, becoming a driven wheel. The flipping process then relies on the change in the center of gravity of the suspended object itself for propulsion: the torque generated by the shift in the object's center of gravity is transmitted through the clamping base 9 to the drag chain 5 connected to its edge, thereby driving the sprocket 3 to rotate freely. During this passive flipping process, the buffer compensators 11 connected to both ends of the drag chain 5 play a crucial role. Their internal elastic elements can effectively absorb the length changes and impact loads caused by the irregular flipping path, providing necessary stroke compensation and buffering for the entire movement, thereby completely eliminating jamming and achieving truly "damped" smooth flipping.

[0022] This device, through a clutch-structure mode switching, can achieve both active and precise reset under no-load conditions and passive, flexible tilting under load, greatly expanding its application range, and is particularly suitable for large finished products such as ultra-long rods. The cable chain 5, wound around the sprocket 3 in the middle, combined with the buffer compensators 11 at both ends, forms a highly efficient dual-compensation system, ensuring the stability and safety of the tilting trajectory. The entire device has a compact structure, with core components such as the drive unit and sprocket 3 fixed to the lifting frame 4, forming a stable force transmission path. Ultimately, it achieves efficient, stable, and automated lifting and tilting operations for large finished products, effectively overcoming the technical bottlenecks of traditional lifting methods that rely on manual labor, have poor adaptability, and are prone to jamming.

[0023] As an optional implementation, the buffer compensator 11 includes a fixed sleeve 7, one end of a spindle 8 is elastically slidably fitted inside the fixed sleeve 7, and the other end of the spindle 8 extends out of the fixed sleeve 7 and is hinged to one end of the drag chain 5. The fixed sleeve 7 is hinged to the edge of the clamping base 9.

[0024] During the flipping process, the drag chain 5 pulls the spindle 8 through the hinge point, allowing it to slide elastically within the fixed sleeve 7. The internal compression spring absorbs length changes and impacts. The hinge between the fixed sleeve 7 and the edge of the clamping base 9 allows for angle self-adaptation, effectively compensating for the flipping stroke and achieving a smooth and unobstructed buffering effect.

[0025] As an optional implementation, the fixed sleeve 7 is provided with a cavity for sliding one end of the spindle 8. An end cap 12 is fixedly connected to one side of the cavity. The end cap 12 is in a limiting fit with one end of the spindle 8, and the other end of the spindle 8 passes through the center of the end cap 12. A compression spring 6 is provided inside the cavity, and the compression spring 6 is coaxially sleeved on the outside of the spindle 8; One end of the compression spring 6 is fixed to the end cap 12, and the other end of the compression spring 6 is fixed to one end of the spindle 8.

[0026] When the cable chain 5 applies tension, one end of the spindle 8 slides within the cavity of the fixed sleeve 7, compressing the compression spring 6 coaxially sleeved on its outer side. One end of the compression spring 6 is fixed to the end cap 12 within the cavity, and the other end is fixed to the spindle 8. Its elastic deformation effectively absorbs changes in chain length and impact energy. The limiting fit between the end cap 12 and the spindle 8 ensures the guidance and stability of the movement, making the buffering process smooth and controllable, ultimately achieving the undamped, adaptive compensation effect of the flipping device.

[0027] As an optional implementation, the bottom of the hanger 4 and the clamping base 9 are rotatably engaged by an intermediate pivot 10.

[0028] During the flipping operation, the clamping base 9 is rotatably engaged with the bottom of the hanger 4 via the intermediate pivot 10. This pivot serves as the core hinge point, allowing the clamping base 9 to rotate flexibly on the hanger 4. When the cable chain's dual compensation mechanism transmits tension or thrust, the clamping base 9 rotates smoothly around the intermediate pivot 10, completing the object's flipping action. This rotatable engagement structure not only ensures the stability of the support but also significantly reduces motion friction, ensuring a smooth and unobstructed flipping process. It is a key foundation for achieving adaptive, undamped flipping.

[0029] As an optional implementation, the clutch structure is an electromagnetic clutch 2. The fixed end of the electromagnetic clutch 2 is fixed to the hanger 4, the input end of the electromagnetic clutch 2 is connected to the output shaft of the drive unit, and the output end of the electromagnetic clutch 2 is connected to the sprocket 3 shaft. When the electromagnetic clutch 2 is energized, the input end and output end of the electromagnetic clutch 2 are separated, and the output end of the electromagnetic clutch 2 is in an idling state. When the electromagnetic clutch 2 is de-energized, the input and output ends of the electromagnetic clutch 2 are engaged, and the input and output ends of the electromagnetic clutch 2 rotate simultaneously.

[0030] The electromagnetic clutch 2, as the core clutch structure, has its fixed end fixed to the hanger 4, its input end connected to the output shaft of the drive unit, and its output end connected to the sprocket 3. When the device is unloaded and needs to be actively rotated, the electromagnetic clutch 2 is de-energized, its input and output ends are engaged, and the power of the drive unit is transmitted to the sprocket 3, making it the driving wheel to drive the entire rotation action. When the device needs to passively rotate an object, the electromagnetic clutch 2 switches to the energized state, the input and output ends separate, the output end enters the idling mode, and the sprocket 3 becomes the driven wheel. At this time, the rotation is completed naturally by the change in the center of gravity of the suspended object.

[0031] This design precisely switches between power transmission and interruption by controlling the on / off state of the electromagnetic clutch 2, enabling the device to operate in both active drive and passive follow-up modes. Its technical advantages significantly enhance the intelligence and adaptability of operation, ensuring both precise and rapid adjustment of the spreader's posture under no-load conditions and flexibility and safety during load flipping. It effectively avoids resistance and impact on the motor under passive operating conditions, making it a key control element for achieving the device's adaptive, undamped flipping function.

[0032] As an optional implementation, the drive unit includes a motor, the output shaft of which is connected to the input end of the electromagnetic clutch 2. The output shaft of the motor drives the input end of the electromagnetic clutch 2 to rotate, and the fixed end of the motor is fixed to the hanger 4.

[0033] The motor's fixed end in the drive unit is securely connected to the hanger 4, and its output shaft directly drives the input end of the electromagnetic clutch 2 to rotate. This structure ensures the stability of the power source, enabling the motor to precisely control the start, stop, and direction of the sprocket 3 via the electromagnetic clutch 2. Its effect is to provide a continuous and reliable power foundation for the tilting device. Combined with the clutch's on / off control, it achieves efficient power transmission during active tilting and rapid power separation during passive tilting, ultimately ensuring the device's smooth operation and responsiveness.

[0034] As an optional implementation, the drive unit also includes a speed reducer 1, the fixed end of which is fixed to the hanger 4, the input end of which is coaxially fixed to the output shaft of the motor, and the output end of which is coaxially fixed to the input end of the electromagnetic clutch 2.

[0035] The drive unit further integrates a reducer 1, whose fixed end is fixedly connected to the hanger 4, its input end is coaxially fixedly connected to the motor output shaft, and its output end is coaxially fixedly connected to the input end of the electromagnetic clutch 2. The reducer 1 converts the high-speed power of the motor into low-speed, high-torque motion suitable for the drive of the sprocket 3 by reducing the rotational speed and increasing the output torque. This structure effectively ensures the smoothness and control precision of the tilting start-stop process, avoiding impacts or jamming caused by insufficient instantaneous torque, thereby improving the reliability and adaptability of the device in heavy lifting operations.

[0036] As an optional implementation, a hinge seat is fixed to the edge of the clamping base 9, and the hinge seat is hinged to one end of the fixing sleeve 7.

[0037] As an optional implementation, the hinged seat is hinged to one end of the fixed sleeve 7 by a high-strength bolt.

[0038] As an optional implementation, the fixed ends of the motor, reducer 1 and electromagnetic clutch 2 are all fixed to the hanger 4 by high-strength bolts.

[0039] Compared to existing technologies, this device uses a lifting device power transmission system to quickly adjust to the required position, vertically clamp large rod-shaped items, lift them to the designated location, and then lower the rod to complete the flipping operation, after which the lifting device detaches. When no object is being lifted, the electromagnetic clutch in the power transmission system is de-energized and engaged, driving the double-compensation mechanism of the cable chain to rotate. The double-compensation mechanism of the cable chain drives the clamping base to achieve a 90° flip. During the rotation, the length of the double-compensation mechanism of the cable chain will change irregularly. By connecting the double-compensation mechanism, the length is adjusted to achieve a stable 90° flip. When clamping and flipping an object, the electromagnetic clutch in the power transmission system is energized and open, turning it into a driven wheel that rotates freely. Relying on the change in the center of gravity of the object, the clamping base changes to the required angle. The double-compensation mechanism of the cable chain cooperates to complete the length compensation and buffering during the flipping process.
