Description

Technical Field

[0001] This utility model relates to the technical field of cargo loading and unloading equipment, specifically to an automatic disassembly and assembly device for suspended lifting gear. Background Technology

[0002] Assembly and disassembly equipment is an automated or semi-automated industrial device used in industrial production, equipment maintenance and other scenarios. Its core function is to realize two-way operation of assembling and disassembling workpieces, parts or components. It usually integrates drive mechanism, execution component, positioning component and control module, and some are equipped with safety protection structure. It can complete efficient and precise assembly and disassembly operations, and has high-frequency operation requirements. It is commonly found in fields such as machinery manufacturing, logistics handling, automobile assembly and so on.

[0003] After the product is processed in the previous process, it is transported to this workstation by an anti-detachment lifting device. The unloading operation requires manual removal of the connecting bolts of the lifting device by hand with a wrench. This operation method is not only labor-intensive, but the bolts will also generate a large reaction force on the wrench during the disassembly process, which can easily cause safety risks. At the same time, the manual disassembly and assembly operation mode also leads to low overall unloading efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic assembly and disassembly device for suspension lifting equipment to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides an automatic suspension and disassembly device, including an anti-detachment suspension device, a suspension device body, a first bolt, a retaining ring, a first spring, and a bushing; the first bolt passes through the suspension device body and has threads at its bottom for detachable connection with the product; the bushing is fixedly installed inside the suspension device body and sleeved on the outer wall of the first bolt; the retaining ring is fixedly sleeved on the middle of the first bolt and located above the suspension device body; the first spring is sleeved on the outer wall of the first bolt and located between the retaining ring and the suspension device body.

[0006] Furthermore, it also includes a displacement assembly, which comprises an anti-detachment lifting device, a lateral drive, a frame, a vertical drive, a horizontal drive, and a tightening wrench; the frame provides support for the overall equipment, the lateral drive is fixedly installed on the crossbeam of the frame, and the vertical drive is fixedly connected to the output end of the lateral drive; the horizontal drive is installed on the output end of the vertical drive, and the output end of the horizontal drive is fixedly connected to the tightening wrench; the working end of the tightening wrench is adapted to the first bolt on the anti-detachment lifting device.

[0007] Furthermore, the lateral drive, vertical drive, and horizontal drive are all electric actuator structures, and the signal input terminals of all three are electrically connected to an external control system.

[0008] Furthermore, the bottom of the frame is provided with a plurality of triangular support pieces, and a support plate is installed on the support pieces and the bottom of the frame.

[0009] Furthermore, the frame is made of high-strength steel, and the support plate has multiple mounting holes. The support plate is fixedly connected to the support member by expansion bolts.

[0010] Furthermore, the first bolt is made of high-strength alloy steel with an anti-rust coating on its surface; the bushing and retaining ring are both made of wear-resistant cast iron, and the first spring is a stainless steel compression spring.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, during disassembly, the external control system controls each drive mechanism to align the tightening wrench with the first bolt. The tightening wrench rotates in the opposite direction to loosen the first bolt. The compressed first spring rebounds, pushing the retaining ring and the first bolt upward to reset. The retaining ring limits the maximum height of the first bolt to prevent it from detaching from the lifting device body until the first bolt is completely detached from the product, thus completing the disassembly. This process greatly reduces manual operation and force application, shortens disassembly and assembly time, adapts to the product conveying rhythm to improve work efficiency, meets continuous production needs, reduces the labor intensity of workers, avoids fatigue, and at the same time avoids the hidden danger of reaction force injury, thus improving work safety.

[0012] 2. In this utility model, the frame provides stable support for the equipment, preventing swaying during horizontal and vertical drive operations. The horizontal drive is fixed to the frame beam and can drive the vertical drive to move horizontally. The vertical drive can drive the horizontal drive to adjust up and down, and the horizontal drive pushes the tightening wrench closer to the first bolt of the anti-dislodgement lifting device. The three work together to achieve flexible movement of the tightening wrench in three directions: horizontal, vertical, and horizontal. Without manual handling or adjustment of the wrench, the tightening wrench can be precisely aligned with the first bolt, reducing manual operation steps, lowering labor intensity, avoiding operational errors due to inaccurate alignment, making the lifting device assembly and disassembly smoother and improving work efficiency. It also reduces direct contact between personnel and equipment / bolts, lowering the risk of safety accidents caused by improper operation. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: See Figures 1-4 As shown, an automatic suspension lifting device includes an anti-detachment lifting device 1, a lifting device body 9, a first bolt 7, a retaining ring 8, a first spring 10, and a bushing 11. The first bolt 7 passes through the lifting device body 9 and has threads at its bottom for detachable connection with the product. The bushing 11 is fixedly installed inside the lifting device body 9 and sleeved on the outer wall of the first bolt 7. The retaining ring 8 is fixedly sleeved in the middle of the first bolt 7 and located above the lifting device body 9. The first spring 10 is sleeved on the outer wall of the first bolt 7 and located between the retaining ring 8 and the lifting device body 9.

[0017] The operator drives the horizontal drive 5 to move the tightening wrench 6 horizontally towards the first bolt 7 on the anti-detachment lifting device 1, ensuring that the working end of the tightening wrench 6 precisely engages with the head of the first bolt 7. The tightening wrench 6 then activates, causing the first bolt 7 to rotate downwards. The thread at the bottom of the first bolt 7 then connects with the product. During this process, the first bolt 7 moves downwards along the inner wall of the bushing 11, and the retaining ring 8 moves downwards synchronously with the first bolt 7, compressing the first spring 10 until the bushing 11 restricts the first bolt 7 from further downward movement, thus completing the installation of the lifting device and the product.

[0018] When disassembly of the lifting device is required, the external control system controls each drive mechanism to precisely align the tightening wrench 6 with the first bolt 7 again. The tightening wrench 6 rotates in the opposite direction to loosen the first bolt 7. At this time, the compressed first spring 10 rebounds, pushing the retaining ring 8 and the first bolt 7 upward to reset. The retaining ring 8 limits the maximum height of the first bolt 7 when unloaded, preventing the first bolt 7 from detaching from the lifting device body 9, until the first bolt 7 is completely detached from the product, completing the disassembly of the lifting device. This significantly reduces manual operation steps and force requirements, greatly shortens the single disassembly and assembly time, and can quickly coordinate with the product conveying rhythm to complete the disassembly and assembly of the lifting device, effectively improving overall work efficiency, meeting the needs of continuous production at the workstation, effectively reducing the labor intensity of workers, avoiding fatigue caused by long-term manual work, and avoiding the safety hazard of reaction force injury, significantly improving operational safety.

[0019] See Figure 1-2 It also includes a displacement assembly, which includes an anti-detachment lifting device 1, a horizontal drive 2, a frame 3, a vertical drive 4, a horizontal drive 5, and a tightening wrench 6. The frame 3 provides support for the overall equipment. The horizontal drive 2 is fixedly installed on the crossbeam of the frame 3. The vertical drive 4 is fixedly connected to the output end of the horizontal drive 2. The horizontal drive 5 is installed on the output end of the vertical drive 4. The output end of the horizontal drive 5 is fixedly connected to the tightening wrench 6. The working end of the tightening wrench 6 is adapted to the first bolt 7 on the anti-detachment lifting device 1.

[0020] Frame 3 provides stable support for the overall equipment, ensuring that components such as the horizontal drive 2 and vertical drive 4 do not shake during operation. The horizontal drive 2, fixed to the crossbeam of frame 3, can drive the vertical drive 4 to move horizontally. The vertical drive 4 can drive the horizontal drive 5 to adjust its position up and down. The horizontal drive 5 can also push the tightening wrench 6 and the first bolt 7 on the anti-dislodgement lifting device 1. The three work together to enable the tightening wrench 6 to move flexibly in the horizontal, vertical and horizontal directions. The tightening wrench 6 can be precisely aligned with the first bolt 7 without manual handling or adjustment of the wrench position, reducing manual operation steps, reducing labor intensity, and avoiding operational errors caused by misalignment when the wrench is held manually. This makes the disassembly and assembly of the lifting device smoother, further improving work efficiency, and also reducing direct contact between humans and equipment and bolts, reducing the risk of safety accidents caused by improper operation.

[0021] See Figure 1-2 The horizontal drive 2, vertical drive 4, and horizontal drive 5 are all electric push rod structures, and the signal input terminals of all three are electrically connected to the external control system.

[0022] The horizontal drive 2, vertical drive 4, and horizontal drive 5 adopt an electric push rod structure, which ensures stable operation and uniform power output. This allows the tightening wrench 6 to move more smoothly in the horizontal, vertical, and horizontal directions, avoiding misalignment with the first bolt 7 due to movement and shaking. The signal input terminals of the three are electrically connected to an external control system, which can precisely set the travel and speed of each drive without the need for manual operation of each drive component, reducing manual intervention and the probability of operational errors. At the same time, the horizontal drive 2, vertical drive 4, and horizontal drive 5 can work together to quickly complete the position adjustment of the tightening wrench 6 and the docking with the first bolt 7, further improving the efficiency of lifting and disassembling, and also making it easier to adapt to the production rhythm of the work station and ensure the continuity of the work process.

[0023] See Figure 1-2 The bottom of frame 3 is provided with multiple triangular support pieces, and support plates are installed on the support pieces and the bottom of frame 3.

[0024] Multiple triangular support plates at the bottom of frame 3 enhance the structural stability of the bottom of frame 3, distribute the weight of frame 3 and the upper horizontal drive 2, vertical drive 4 and other components, and prevent frame 3 from deforming or tilting due to concentrated force. The support plates and the support plate installed at the bottom of frame 3 further expand the contact area between frame 3 and the support surface, making frame 3 more stable when placed, reducing the impact of vibration generated by the operation of horizontal drive 2 and vertical drive 4 on the stability of frame 3, and ensuring that the tightening wrench 6 will not have alignment deviation due to the shaking of frame 3 during the movement and disassembly of the first bolt 7, thus ensuring the smooth progress of lifting tool disassembly and assembly operations.

[0025] See Figure 1 The frame 3 is made of high-strength steel, and the support plate has multiple mounting holes. The support plate is fixedly connected to the support component by expansion bolts.

[0026] Frame 3 is made of high-strength steel, capable of bearing the weight of components such as the horizontal drive 2, vertical drive 4, and tightening wrench 6. It also resists external forces and vibrations generated during equipment operation, preventing frame 3 from bending or breaking and extending the overall service life of the equipment. Multiple mounting holes on the support plate allow for easy adjustment of the fixing position of the expansion bolts according to actual installation needs, adapting to different support installation scenarios. The support plate is fixedly connected to the support components through expansion bolts, which can stably transfer the weight of frame 3 and the components above it to the support components, further enhancing the stability of frame 3 and preventing the equipment from shifting or shaking during lifting and disassembly operations. It also ensures the alignment accuracy of tightening wrench 6 and the first bolt 7, guaranteeing smooth operation.

[0027] See Figure 1 The first bolt 7 is made of high-strength alloy steel with an anti-rust coating on the surface; the bushing 11 and the retaining ring 8 are both made of wear-resistant cast iron; and the first spring 10 is a stainless steel compression spring.

[0028] The first bolt 7 is made of high-strength alloy steel, which can withstand the external force when the lifting device is connected to the product, and avoid breakage during long-term use. The anti-rust coating on the surface can prevent the bolt from rusting due to contact with sewage, dust and other environmental factors, ensuring smooth and non-jamming threads during disassembly and assembly. The bushing 11 and the retaining ring 8 are made of wear-resistant cast iron, which is not easy to wear during repeated movement and friction of the first bolt 7, extending the service life of the components and reducing the trouble of frequent replacement. The first spring 10 is a stainless steel compression spring, which is not easy to rust and fail due to long-term compression or contact with a humid environment, and can stably provide the return spring force, ensuring that the first bolt 7 can be reset in time after disassembly. With the improved durability of each component, the frequency of equipment maintenance can be reduced, ensuring the continuous and stable operation of lifting device disassembly and assembly.
