Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a cab lifting device and lifting system. Background Technology

[0002] With the development of automotive manufacturing technology, automated lifting technology has gradually become an important direction in the industry. This technology, characterized by its high efficiency, safety, and precision, has been widely applied. In modern automobile manufacturing, the lifting and transfer of the cab is a crucial step, directly affecting production line efficiency and product quality.

[0003] In existing technologies, the hoisting of the cab mainly relies on manual operation and traditional lifting tools. The hoisting process is typically completed using simple lifting tools and equipment. Specific steps include using the lifting tools to lift the cab, manually adjusting its position, then transporting it to the designated location and securing it. Traditional hoisting equipment includes cranes, simple lifting tools, and manual adjustment devices, relying on the operator's experience and skill.

[0004] However, current traditional hoisting methods and equipment rely on manual operation, which is labor-intensive. Operators are required to work under high load for extended periods, leading to fatigue and increased operational risks. Manual operation makes it difficult to ensure precise positioning of the cab during hoisting, easily causing positional deviations that affect the cab's installation quality and subsequent assembly. Traditional hoisting equipment is prone to swaying and vibration during operation, causing instability in the cab and increasing operational difficulty and safety risks. Summary of the Invention

[0005] Therefore, it is necessary to provide a cab lifting tool and lifting system to address the aforementioned problem of instability in the cab during hoisting.

[0006] This application provides a cab lifting device, including a base frame, a positioning assembly and a locking assembly. The base frame includes two first longitudinal beams and several cross beams. The two first longitudinal beams are connected by the several cross beams. One end of the base frame also has a lifting structure for connecting a transfer device.

[0007] The positioning component includes a first positioning structure, which is disposed on the crossbeam and extends in a direction perpendicular to the plane of the base frame. The end of the first positioning structure away from the base frame is adapted to the shape of the cab to be hoisted, and is used to limit the displacement of the cab to be hoisted in the vertical direction.

[0008] The locking assembly is mounted on the crossbeam and includes a driving member and a rotatably mounted locking member. The locking member rotates along the crossbeam under the drive of the driving member to switch between a locked state that is close to the cab to be hoisted and an unlocked state that is away from the cab to be hoisted.

[0009] In one embodiment, the base frame further includes a second longitudinal beam disposed between two first longitudinal beams and connected to a plurality of the crossbeams;

[0010] The hoisting structure is mounted on the second longitudinal beam and extends in a direction perpendicular to the plane of the base frame.

[0011] In one embodiment, the hoisting structure includes a first hoisting beam and a second hoisting beam, the first hoisting beam being connected to one end of the second longitudinal beam, the first hoisting beam being slidably connected to the second hoisting beam, and the extension directions of the first hoisting beam and the second hoisting beam being parallel.

[0012] The hoisting structure also includes a connector, one end of which is connected to the second hoisting beam and the other end of which is connected to the transfer device.

[0013] In one embodiment, the positioning component further includes a second positioning structure disposed at the end of the first longitudinal beam away from the lifting structure, for limiting the horizontal displacement of the cab to be lifted.

[0014] In one embodiment, the locking assembly further includes a support and a pivot, the support being used to connect the pivot and the drive to the base frame;

[0015] The locking component includes a rotating plate and a locking block. The locking block is connected to the rotating shaft via the rotating plate. The locking block is adapted to the cab to be hoisted. The driving component drives the rotating shaft and the rotating plate to rotate, thereby driving the locking block to engage with the cab to be hoisted, further restricting the horizontal displacement of the cab to be hoisted.

[0016] In one embodiment, the first positioning structure includes a mounting bracket, a plurality of positioning blocks and a block frame, wherein the positioning blocks and the block frame are correspondingly connected, the positioning blocks are connected to the mounting bracket through the block frame, and the plurality of positioning blocks and the block frame are connected to the crossbeam through the mounting bracket.

[0017] The positioning block has a positioning groove adapted to the cab to be hoisted, which is used to limit the vertical displacement of the cab to be hoisted.

[0018] In one embodiment, the hoisting structure has a first reinforcing structure between itself and the second longitudinal beam, and the mounting bracket has a second reinforcing structure between itself and the crossbeam.

[0019] In one embodiment, the locking block is a locking block made of nylon, the positioning block is a positioning block made of nylon, and the second positioning structure is a second positioning structure made of nylon.

[0020] In one embodiment, the connector and the second lifting beam, as well as the connector and the transfer device, are all welded together, and stress is eliminated through aging treatment;

[0021] The positioning block and the block frame, the block frame and the mounting bracket, and the second positioning structure and the first longitudinal beam are all bolted together.

[0022] This application also provides a hoisting system, including the above-mentioned cab-mounted hoist, and further including a transfer device. The transfer device includes a guide component and a drive component. One end of the guide component is connected to a connector, and the other end is slidably connected to a track. The drive component is connected to the guide component and is used to drive the guide component to travel along the track.

[0023] The aforementioned cab-mounted spreader, with its frame structure consisting of two longitudinal beams and several transverse beams, provides excellent rigidity and strength, ensuring stable support of the cab's weight during lifting. The lifting structure allows for easy connection to various transfer devices, improving its applicability and flexibility. The first positioning structure is adapted to the cab's shape, effectively limiting its vertical displacement and ensuring stability and safety during lifting. The positioning structure design ensures the cab will not slide up and down during lifting, reducing potential safety hazards. The locking assembly controls the rotation of the locking element through a drive component, enabling rapid locking and unlocking of the cab and improving work efficiency. In the locked state, the locking element firmly abuts against the cab, preventing movement during lifting and enhancing the safety of the lifting operation. The locking element can switch between locked and unlocked states, facilitating adaptation to cabs of different sizes and shapes.

[0024] The design of the base frame, positioning components, and locking components achieves high stability, high safety, and ease of operation for the spreader. The base frame provides strength and stability, the positioning components ensure precise positioning and anti-slip properties of the cab, and the locking components provide convenient operation and reliable locking. These components work together to enable the spreader to efficiently and safely complete cab lifting tasks in practical use.

[0025] The aforementioned cab-mounted lifting system automates the lifting process through its drive components, reducing manual intervention and improving efficiency. The guide components ensure smooth sliding of the spreader along the track, providing a high-precision movement path, reducing operational errors, and enhancing the safety and reliability of the lifting process. Integrating the cab-mounted spreader and transfer device into a single system simplifies the operation process and enhances the coordination and consistency of all components. On production lines requiring high-frequency, continuous lifting operations, automated lifting systems can significantly improve production efficiency and reduce labor costs. The precise guidance and controllable movement functions of the lifting system are suitable for lifting tasks with high positioning accuracy requirements, ensuring the accuracy of each lifting operation. In environments requiring complex operations, automated lifting systems reduce operational difficulty by minimizing manual intervention, thereby improving the overall safety and stability of the operation.

[0042] See Figure 1 An embodiment of the present invention provides a cab lifting device, including a base frame 100, a positioning component 200 and a locking component 300. The base frame 100 includes two first longitudinal beams 110 and several cross beams 120. The two first longitudinal beams 110 are connected by several cross beams 120. One end of the base frame 100 also has a lifting structure 130 for connecting a transfer device 400.

[0043] The positioning assembly 200 includes a first positioning structure 210, which is disposed on the crossbeam 120 and extends in a direction perpendicular to the plane of the base frame 100. The end of the first positioning structure 210 away from the base frame 100 is adapted to the shape of the cab to be hoisted, and is used to limit the displacement of the cab to be hoisted in the vertical direction.

[0044] The locking assembly 300 is disposed on the crossbeam 120 and includes a drive member 310 and a rotatably disposed locking member 320. The locking member 320 rotates along the crossbeam 120 under the drive of the drive member 310 to switch between a locked state that is close to the cab to be hoisted and an unlocked state that is away from the cab to be hoisted.

[0045] The frame structure, consisting of two longitudinal beams and several transverse beams 120, provides excellent rigidity and strength, ensuring stable support of the cab's weight during hoisting. The hoisting structure 130 allows the spreader to be easily connected to different transfer devices 400, improving its applicability and flexibility. The first positioning structure 210 is adapted to the shape of the cab, effectively limiting its vertical displacement and ensuring stability and safety during hoisting. The positioning structure design ensures the cab will not slide up and down during hoisting, reducing potential safety hazards. The locking assembly 300 controls the rotation of the locking member 320 via the drive member 310, enabling rapid locking and unlocking of the cab and improving work efficiency. In the locked state, the locking member 320 firmly abuts against the cab, preventing movement during hoisting and enhancing the safety of the hoisting operation. The locking member 320 can switch between locked and unlocked states, facilitating adaptation to cabs of different sizes and shapes.

[0046] The design of the base frame 100, positioning assembly 200, and locking assembly 300 achieves high stability, high safety, and ease of operation for the spreader. The base frame 100 provides strength and stability, the positioning assembly 200 ensures precise positioning and anti-slip of the cab, and the locking assembly 300 provides convenient operation and reliable locking. These components work together to enable the spreader to efficiently and safely complete cab lifting tasks in practical use.

[0047] See Figure 1 and Figure 2 In one embodiment, the base frame 100 further includes a second longitudinal beam 140, which is disposed between two first longitudinal beams 110 and connected to a plurality of crossbeams 120.

[0048] The hoisting structure 130 is mounted on the second longitudinal beam 140 and extends in a direction perpendicular to the plane of the base frame 100.

[0049] The second longitudinal beam 140 connects with several cross beams 120, further enhancing the overall rigidity and structural stability of the base frame 100. This allows for a more even distribution of the load, reducing deformation of the base frame 100 during hoisting. The addition of the second longitudinal beam 140 enables a more even distribution of the load on the base frame 100, especially when bearing a heavy cab, effectively reducing the stress on a single longitudinal beam. The three longitudinal beams working together better resist torsional moments, improving the adaptability of the spreader in complex hoisting environments.

[0050] By placing the lifting structure 130 on the second longitudinal beam 140, the lifting force can be more evenly distributed across the entire base frame 100, reducing eccentric loads during lifting and improving overall stability. The lifting structure 130, designed perpendicular to the plane of the base frame 100, allows the lifting force to be directly transmitted to all connection points of the base frame 100 via the second longitudinal beam 140, optimizing the force transmission path and reducing stress concentration. The lifting structure 130's central location on the second longitudinal beam 140 enhances the structure's symmetry and further improves the balance and stability of the lifting equipment during lifting.

[0051] See Figure 2 In one embodiment, the hoisting structure 130 includes a first hoisting beam 131 and a second hoisting beam 132. The first hoisting beam 131 is connected to one end of the second longitudinal beam 140, and the first hoisting beam 131 and the second hoisting beam 132 are slidably connected. The extension directions of the first hoisting beam 131 and the second hoisting beam 132 are parallel.

[0052] The hoisting structure 130 also includes a connector 133, one end of which is connected to the second hoisting beam 132 and the other end is connected to the transfer device 400.

[0053] The sliding connection design allows for fine-tuning of the first lifting beam 131 and the second lifting beam 132 during commissioning, thereby precisely adjusting the position of the lifting structure 130. This design provides greater adjustment flexibility, ensuring that the spreader can adapt to cabs of different sizes and shapes. During actual processing and lifting, sliding adjustment and final locking ensure high-precision positioning of the spreader in actual operation, thus improving the accuracy and safety of the lifting process. The parallel design of the first lifting beam 131 and the second lifting beam 132 allows them to share the lifting force, enhancing the strength and load-bearing capacity of the entire lifting structure 130.

[0054] The connector 133 design makes the connection between the lifting structure 130 and the transfer device 400 simpler and faster, improving operational efficiency. Connector 133 provides a stable connection method, ensuring that the lifting structure 130 can be securely connected to the transfer device 400 during lifting and transportation, reducing the risk of accidental detachment. The design of connector 133 can adapt to different types of transfer devices 400, making the lifting equipment more versatile and increasing its applicability.

[0055] See Figure 1In one embodiment, the positioning component 200 further includes a second positioning structure 220, which is disposed at the end of the first longitudinal beam 110 away from the lifting structure 130, and is used to limit the horizontal displacement of the cab to be lifted. Specifically, in this embodiment, the second positioning structure 220 is a lower positioning block disposed at the lower end of the first longitudinal beam 110, and its side abuts against the cab, thereby preventing the cab from deflecting or horizontally displacing with the first positioning structure 210 as a fulcrum when it is fixed above by the first positioning structure 210.

[0056] The introduction of the second positioning structure 220, especially the lower positioning block located at the lower end of the first longitudinal beam 110, effectively restricts the horizontal displacement of the cab, enhancing the comprehensiveness of positioning. By adding a positioning block at the bottom of the cab, which abuts against the side of the cab, it prevents the cab from deflecting when using the first positioning structure 210 as a fulcrum. This design ensures that the cab maintains the correct position during hoisting, avoiding instability or accidents caused by deflection. The combined effect of the first positioning structure 210 and the second positioning structure 220 effectively restricts the cab in both the vertical and horizontal directions, greatly improving the stability and safety of the hoisting process. In practical applications, the shape and stress conditions of the cab may be complex; by adding the second positioning structure 220, it is possible to better adapt to these complex working conditions and ensure the reliability of hoisting operations.

[0057] The introduction of a second positioning structure 220 further enhances the positioning component 200, more effectively limiting the horizontal displacement of the cab, preventing deflection, and improving the stability and safety of the lifting process. The first positioning structure 210 handles vertical positioning, while the second positioning structure 220 handles horizontal positioning; their combination ensures the cab remains highly stable during lifting. The second positioning structure 220 is designed as a lower positioning block, simple in structure yet highly functional, significantly improving positioning performance without adding excessive complexity. This design is suitable not only for standard-sized and shaped cabs but also provides good positioning performance for irregularly shaped or complex-stressed cabs.

[0058] See Figure 4 In one embodiment, the locking assembly 300 further includes a support member 323 and a rotating shaft 340. The support member 323 is used to connect the rotating shaft 340 and the drive member 310 to the base frame 100. In this embodiment, the support member 323 is a mounted bearing, and the rotating shaft 340 passes through the mounted bearing, with the bearing housing connected to the base frame 100.

[0059] The locking component 320 includes a rotating plate 321 and a locking block 322. The locking block 322 is connected to the rotating shaft 340 via the rotating plate 321. The locking block 322 is adapted to the cab to be hoisted. The driving component 310 drives the rotating shaft 340 and the rotating plate 321 to rotate, thereby driving the locking block 322 to engage with the cab to be hoisted, further restricting the horizontal displacement of the cab. In this embodiment, the locking block 322 has a groove. After the rotating plate 321 rotates, the locking block 322 engages with the edge of the side wall at the middle position of the cab, improving the fixing effect of hoisting and preventing the cab from falling off during hoisting.

[0060] The mounted bearing 323 serves as a support component, providing a stable and low-friction connection that allows the rotating shaft 340 to rotate smoothly, improving the reliability of the locking assembly 300. The use of the mounted bearing reduces wear on the rotating shaft 340 during rotation, extending the service life of the locking assembly 300. The rotating shaft 340 is connected to the base frame 100 via the mounted bearing and is connected to the rotating plate 321, efficiently transmitting power to the drive component 310 and achieving stable rotation of the locking block 322. The combination of the rotating plate 321 and the rotating shaft 340 allows the drive component 310 to precisely control the rotation angle of the locking block 322, ensuring that the locking block 322 accurately engages in the predetermined position within the cab. The groove design of the locking block 322 allows it to engage more securely with the edge of the cab's side wall, providing stronger locking force and preventing the cab from sliding or falling off during hoisting. The groove matches the edge of the side wall in the middle of the cab, improving the fixing effect of the locking block 322 and ensuring the cab remains stable during hoisting.

[0061] The mounted bearing 323 serves as a support component, providing stable support for the rotating shaft 340, reducing friction and wear, and improving the durability of the locking assembly 300. The design of the rotating shaft 340 and the rotating plate 321 allows the drive component 310 to efficiently and precisely control the rotation of the locking block 322, achieving stable locking operation. The locking block 322 has grooves that can firmly engage with the edge of the cab side wall, preventing the cab from moving or falling off during hoisting, thus improving the safety and reliability of the overall hoisting process.

[0062] See Figure 3 In one embodiment, the first positioning structure 210 includes a mounting bracket 211, a plurality of positioning blocks 212 and a block frame 213, the positioning blocks 212 and the block frame 213 are correspondingly connected, the positioning blocks 212 are connected to the mounting bracket 211 through the block frame 213, and the plurality of positioning blocks 212 and the block frame 213 are connected to the crossbeam 120 through the mounting bracket 211.

[0063] The positioning block 212 has a positioning groove adapted to the cab to be lifted, which is used to limit the vertical displacement of the cab to be lifted.

[0064] The mounting bracket 211 serves as the basic structure, connecting the support block frame 213 and the crossbeam 120, thus realizing the modular design of the positioning component 200, facilitating installation and maintenance. The positioning support block 212 is correspondingly connected to the support block frame 213, and connected to the mounting bracket 211 via the support block frame 213. This modular design allows the positioning component 200 to be flexibly adjusted and replaced to adapt to different models and sizes of cabs. The positioning support block 212 has a positioning groove adapted to the cab, which can precisely limit the vertical displacement of the cab, ensuring the cab remains stable during hoisting. The positioning groove design effectively prevents the cab from sliding up and down during hoisting, providing reliable vertical positioning and improving the safety of hoisting operations. The connection between the mounting bracket 211 and the crossbeam 120 provides a solid foundation, ensuring the positioning component 200 remains stable under load. Multiple positioning supports 212 and support block frames 213 work together to distribute force evenly, reducing the risk of excessive force on a single support block and extending the service life of the component.

[0065] Through refined design of the first positioning structure 210, the positioning component 200 achieves a significant improvement in positioning accuracy and stability. The modular design of the mounting bracket 211, support block frame 213, and positioning support block 212 allows for flexible adjustment and replacement of the components, offering strong adaptability and facilitating maintenance and upgrades. The positioning groove design of the positioning support block 212 provides high-precision vertical positioning, preventing vertical displacement of the cab during hoisting and ensuring safety and stability. Multiple positioning support blocks 212 and support block frame 213 are connected to the crossbeam 120 via the mounting bracket 211, resulting in even force distribution, enhancing the overall structural stability, and reducing the risk of wear and failure of individual components.

[0066] See Figure 2 and Figure 3 In one embodiment, a first reinforcing structure is provided between the hoisting structure 130 and the second longitudinal beam 140, and a second reinforcing structure is provided between the mounting bracket 211 and the crossbeam 120. Specifically, in this embodiment, the first reinforcing structure is a reinforcing rib provided between the first hoisting beam 131 and the second longitudinal beam 140, and the second reinforcing structure is a support leg provided between the mounting bracket 211 and the crossbeam 120, forming a triangular structure.

[0067] The reinforcing ribs provide additional support between the first lifting beam 131 and the second longitudinal beam 140, significantly improving the load-bearing capacity of the lifting structure 130 and reducing beam deformation and stress concentration during lifting. The introduction of the reinforcing ribs increases the rigidity of the lifting structure 130, enabling it to remain stable under heavy loads and preventing structural deformation or instability.

[0068] The support legs form a triangular structure between the mounting bracket 211 and the crossbeam 120, providing extremely high structural stability. Triangular structures are commonly used stabilizing structures in engineering, effectively dispersing stress and preventing displacement or deformation of the support under load. By increasing structural rigidity, the support legs reduce vibrations that may occur during hoisting, improving operational smoothness and safety.

[0069] In scenarios requiring the hoisting of heavy-duty cabs, the reinforcing structure provides the necessary load-bearing capacity and rigidity, ensuring a safe and reliable hoisting process. The introduction of the reinforcing structure reduces structural deformation and improves the precision of hoisting operations, making it suitable for hoisting tasks requiring high positioning accuracy. The addition of the reinforcing structure effectively disperses stress, reduces structural fatigue and wear, and extends the service life of the lifting equipment, making it suitable for long-term, high-frequency use scenarios.

[0070] In one embodiment, the locking block 322 is a nylon locking block 322, the positioning support block 212 is a nylon positioning support block 212, and the second positioning structure 220 is a nylon second positioning structure 220.

[0071] The nylon locking block 322 boasts high strength and wear resistance, maintaining a stable locking effect over long-term use and preventing the cab from sliding or detaching during lifting. The softer nylon material, compared to metal, reduces damage to the cab surface, preventing scratches or indentations during locking. The nylon positioning block 212, with its high-strength and wear-resistant positioning grooves, precisely limits the vertical displacement of the cab, ensuring stability during lifting. Its self-lubricating properties and wear resistance allow the positioning block 212 to maintain good condition even with frequent contact and friction, reducing maintenance requirements. The nylon second positioning structure 220 (as in the lower positioning block) effectively limits horizontal displacement by contacting the side of the cab, preventing the cab from shifting during lifting. The shock-absorbing properties of nylon help absorb and cushion the impact forces generated during horizontal movement of the cab, improving the smoothness of the lifting process. Its corrosion and chemical resistance allows the lifting equipment to maintain excellent performance under various environmental conditions, expanding its applicability.

[0072] In one embodiment, the connector 133 and the second hoisting beam 132, as well as the connector 133 and the transfer device 400, are all welded together, and stress is eliminated through aging treatment.

[0073] The positioning block 212 and the block frame 213, the block frame 213 and the mounting bracket 211, the second positioning structure and the first longitudinal beam 110 are all bolted together.

[0074] The welded connection provides very high strength and rigidity, ensuring that the connection between connector 133 and the second lifting beam 132 and transfer device 400 can withstand large loads and external forces. Aging treatment eliminates internal stresses generated during welding, preventing material fatigue and fracture caused by stress concentration, thus improving the durability and reliability of the connection. The welded connection provides a high-strength joint, ensuring that connector 133 will not break or loosen due to excessive load during lifting. Aging treatment eliminates residual internal stresses from the welding process, reducing the risk of material fatigue and fracture, and extending the service life of the connection.

[0075] The bolted connections allow for more flexible connections between the positioning block 212 and the block frame 213, between the block frame 213 and the mounting bracket 211, and between the second positioning structure 220 and the first longitudinal beam 110, facilitating installation, disassembly, maintenance, and adjustment. The bolted connections provide reliable fixation, ensuring that components are not easily loosened or displaced under stress, thus guaranteeing the stability of the overall structure. Furthermore, the bolted connection design allows for positional adjustments of components as needed, adapting to cabs of different sizes and shapes, improving the applicability of the lifting equipment. The bolted connections also facilitate easier installation and disassembly of components, enabling regular maintenance and replacement, and reducing maintenance costs. Finally, the bolted connections provide reliable fixation, ensuring that components remain stable under stress, preventing loosening or displacement, and guaranteeing safety during the lifting process.

[0076] In scenarios requiring the lifting of heavy-duty cabs, welded connections provide the necessary high-strength joints, ensuring a safe and reliable lifting process. The flexibility and adjustability of bolted connections allow the spreader to adapt to cabs of different sizes and shapes, catering to diverse lifting needs. The durability of welded connections and the ease of maintenance of bolted connections make the spreader suitable for long-term, high-frequency use environments, ensuring operational continuity and stability.

[0077] See Figure 5 An embodiment of the present invention also provides a hoisting system, including the above-mentioned cab hoist and a transfer device 400. The transfer device 400 includes a guide component 410 and a drive component 420. One end of the guide component 410 is connected to the connector 133 and the other end is slidably connected to the track. The drive component 420 is connected to the guide component 410 and is used to drive the guide component 410 to move along the track.

[0078] Integrating the cab-mounted spreader and transfer device 400 into a single lifting system enables coordinated lifting and transfer operations, reducing the complexity of individual operations and improving efficiency. One end of the guide assembly 410 connects to the connector 133, while the other end slides along the track, ensuring precise movement of the spreader along the predetermined track during lifting and reducing operational errors. The sliding connection between the guide assembly 410 and the track provides a smooth movement path, reducing vibration and swaying during movement and improving the stability and safety of the lifting process.

[0079] The drive assembly 420 automates the lifting process, reducing manual intervention and improving lifting efficiency. The guide assembly 410 ensures the spreader slides smoothly along the track, providing a high-precision movement path, reducing operational errors, and enhancing the safety and reliability of the lifting process. Integrating the cab spreader and transfer device 400 into a single system simplifies the operation process and enhances the coordination and consistency of each component. On production lines requiring high-frequency, continuous lifting operations, automated lifting systems can significantly improve production efficiency and reduce labor costs. The precise guidance and controllable movement functions of the lifting system are suitable for lifting tasks with high positioning accuracy requirements, ensuring the accuracy of each lifting operation. In environments requiring complex operations, automated lifting systems reduce operational difficulty by minimizing manual intervention, thereby improving the overall safety and stability of the operation.
