Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to a lifting tool for a flywheel assembly of a small press, which can lift the flywheel assembly that needs maintenance from a small press in a space-constrained environment. Background Technology

[0002] Presses are widely used in processes such as cutting, punching, blanking, bending, riveting, and forming due to their versatility and high production efficiency. They process metal parts by applying strong pressure to metal blanks, causing plastic deformation and fracture. Some presses are equipped with flywheel assemblies, which are typically quite heavy and require lifting equipment for transport, assembly, and maintenance.

[0003] In actual after-sales maintenance, some customers using small presses face numerous challenges. Due to limited factory space, low ceilings, and cramped space around the press, many factories cannot install overhead cranes. In such cases, customers often have to build their own simple lifting devices to lift the flywheel assembly. Common simple lifting devices include... Figure 1 As shown, the T-shaped seat 100, support beam 101, and fixed seat 102 are assembled and fixed to the platform of a small press. The cantilever beam 103 is then inserted into the T-shaped seat 100, and its tail end is secured with a locking ring 104. In use, the flywheel assembly is detached from the platform by pushing the cantilever beam 103 to move it left and right and by applying a lever arm to its tail end for rotation. However, this simple lifting device has significant drawbacks. Due to the cantilever structure, the farther the lifting position, the greater the bending moment applied to the cantilever beam 103 and its connecting components (such as the T-shaped seat 100, support beam 101, and fixed seat 102). For the flywheel assembly in a dry clutch, its weight is relatively light, allowing for easy lifting. However, for the flywheel assembly in a wet clutch, its weight is greater. Under long cantilever and heavy working conditions, the platform steel plate is prone to exceeding its strength limit, posing a serious safety hazard.

[0004] To address the issue of the flywheel assembly in wet clutches being unable to be lifted using a cantilever structure, the current approach is to disassemble the flywheel assembly into multiple parts and then remove each part using additional tools. This method reduces the weight of individual components by disassembling the flywheel assembly, thus simplifying the removal of the flywheel assembly from the workbench. However, this method not only increases the complexity and time cost of maintenance but also risks damaging components during disassembly and reassembly, further increasing maintenance costs.

[0005] In summary, existing technologies have significant limitations in the lifting of flywheel assemblies from small presses. On one hand, simple lifting devices pose safety hazards when supporting heavy flywheel assemblies in wet clutches; on the other hand, disassembling the flywheel assembly before lifting it not only increases maintenance complexity and time costs but may also damage components. Therefore, a new type of lifting tool is needed to safely and efficiently lift flywheel assemblies from small presses in space-constrained environments, thereby improving maintenance efficiency and reducing maintenance costs. Summary of the Invention

[0006] For customers using small presses whose factory space is limited and cannot accommodate overhead cranes, this utility model provides a flywheel assembly lifting tool for small presses. This tool can safely and efficiently lift the flywheel assembly from the small press, thereby improving the maintenance efficiency of the flywheel assembly and reducing maintenance costs.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a small press flywheel assembly lifting device, characterized in that it includes:

[0008] Support base, used to be clipped onto the main board of a small press;

[0009] A triangular bracket, distributed parallel to the support base, is used to be placed directly behind the platform of a small press.

[0010] A crossbeam is erected between the top of the support base and the top of the triangular bracket, and is supported by the triangular bracket;

[0011] The hoist, which is slidably mounted on the crossbeam via pulleys, is used to hoist the flywheel assembly.

[0012] The bottom of the support base is designed with a U-shaped groove for engagement, which is adapted to the main platen of the small press. A locking device is provided on one or both sides of the engagement portion to secure the main platen. The U-shaped groove design, adapted to the main platen, further enhances the connection stability between the support base and the main platen, providing a more reliable support foundation for the hoisting process. The locking device ensures that the main platen is firmly locked within the U-shaped groove, effectively preventing loosening or detachment of the support base from the main platen during hoisting, thus ensuring the safety of the flywheel assembly during hoisting.

[0013] The locking device is a locking screw located on the side wall of the snap-fit ​​part. Using a locking screw (such as an internal hex screw) as the locking device, the screw head presses against the main plate of the platform to achieve locking. This design is simple and reliable, effectively ensuring a tight connection between the support base and the main plate of the platform, further enhancing the stability of the hoisting process.

[0014] The top of the support base is equipped with a position adjustment mechanism that allows the support base to move on the crossbeam to adapt to hoisting operations in different spaces. The design of the position adjustment mechanism enables the support base to move on the crossbeam, thereby adapting to different spatial requirements and hoisting positions, improving the flexibility and versatility of the lifting equipment, and enabling it to better adapt to various complex hoisting environments.

[0015] The position adjustment mechanism includes a lower support plate, an upper pressure plate, and screws. The lower support plate is fixed to the top of the support base. The upper pressure plate is distributed parallel to the lower support plate directly above it and connected as a whole by multiple screws, forming a through hole for the crossbeam to pass through. Loosening the screws adjusts the fixed position of the support base on the crossbeam. This position adjustment mechanism, consisting of the lower support plate, upper pressure plate, and screws, allows for precise adjustment of the fixed position of the support base on the crossbeam, improving the adaptability of the lifting device.

[0016] The upper part of the triangular bracket is provided with diagonal bracing to enhance the supporting force on the crossbeam. This diagonal bracing strengthens the support for the crossbeam, further improving the load-bearing capacity and stability of the entire lifting device. This helps ensure that the crossbeam does not deform or break under excessive load when lifting heavy flywheel assemblies, thus extending the service life of the lifting device.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1) By combining the support base, triangular bracket, crossbeam and hoist, a stable hoisting structure is formed, which can effectively support and hoist the flywheel assembly and ensure the stability of the hoisting process.

[0019] 2) The support seat is clamped on the main board of the small press, and the triangular bracket is placed on the ground directly behind the small press. That is, there is support on both sides of the crossbeam, which enables the lifting device to bear the heavy flywheel assembly.

[0020] 3) The triangular bracket design enhances the stability and load-bearing capacity of the lifting device, making it suitable for heavier flywheel assemblies.

[0021] 4) The overall design enables the lifting device to safely and efficiently lift the flywheel assembly in space-constrained environments, improving maintenance efficiency and reducing maintenance costs.

[0022] 5) The hoist is slidably mounted on the crossbeam via pulleys, which makes it easy to adjust the hoisting position according to hoisting requirements, improving the convenience of operation. Moreover, the operator can carry out hoisting operations within a safe distance, reducing the risk of direct contact with heavy objects. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] This utility model proposes a small press flywheel assembly lifting device, such as... Figure 2 , Figure 3 and Figure 4 As shown, it includes: a support base 1, used to be clamped onto the main board 9 of the small press; a triangular bracket 2, distributed parallel to the support base 1, used to be placed directly behind the platform of the small press; a crossbeam 3, erected between the top of the support base 1 and the top of the triangular bracket 2, the top of the triangular bracket 2 and the crossbeam 3 are fixed together by hexagonal screws, one end of the crossbeam 3 is supported by the triangular bracket 2, and the other end of the crossbeam 3 is supported by the support base 1 clamped onto the main board 9 of the small press; a hoist (not shown in the figure), slidably mounted on the crossbeam 3 by a pulley 4, used to hoist the flywheel assembly, the pulley 4 is detachably mounted on the crossbeam 3 and can be inserted from the middle position of the crossbeam 3.

[0029] Further specifying, the bottom of the support base 1 is designed as a snap-fit ​​part 12 with a U-shaped groove 11. The U-shaped groove 11 is adapted to the main plate 9 of the small press. A locking device for locking the main plate 9 is provided on one or both sides of the snap-fit ​​part 12. The locking device is a locking screw 13 provided on the side wall of the snap-fit ​​part 12. The U-shaped groove 11 is designed to adapt to the main plate 9, which further enhances the connection stability between the support base 1 and the main plate 9, providing a more reliable support foundation for the hoisting process. The locking device can ensure that the main plate 9 is tightly locked in the U-shaped groove 11, effectively preventing the support base 1 from loosening or separating from the main plate 9 during the hoisting process, and ensuring the safety of the flywheel assembly hoisting process. Using a locking screw 13 (such as an internal hex screw) as the locking device, the locking is achieved by the head of the locking screw 13 pressing against the main plate 9. This design is simple and reliable, and can effectively ensure the tight connection between the support base 1 and the main plate 9, further enhancing the stability of the hoisting process.

[0030] Further, the top of the support base 1 is equipped with a position adjustment mechanism 5 that allows the support base 1 to move on the crossbeam 3 to adapt to hoisting operations in different spaces. The design of the position adjustment mechanism 5 enables the support base 1 to move on the crossbeam 3, thereby adapting to different spatial requirements and hoisting positions, improving the flexibility and versatility of the lifting equipment, and enabling it to better adapt to various complex hoisting environments. The position adjustment mechanism 5 includes a lower support plate 51, an upper pressure plate 52, and screws 53. The lower support plate 51 is fixed to the top of the support base 1, and the upper pressure plate 52 is distributed parallel to the top of the lower support plate 51 and connected as a whole by multiple screws 53 to form a through hole for the crossbeam 3 to pass through. The fixed position of the support base 1 on the crossbeam 3 can be adjusted by loosening the screws 53, and the screws 53 can be tightened after the position is adjusted. Through the position adjustment mechanism 5 composed of the lower support plate 51, the upper pressure plate 52, and the screws 53, the fixed position of the support base 1 on the crossbeam 3 can be precisely adjusted. This design improves the adaptability of the lifting equipment.

[0031] Furthermore, the upper part of the triangular support 2 is provided with a diagonal brace 21 to enhance the supporting force on the crossbeam 3. The diagonal brace 21 on the upper part of the triangular support 2 strengthens the supporting force on the crossbeam 3, further improving the load-bearing capacity and stability of the entire lifting device. This helps ensure that the crossbeam 3 will not deform or be damaged due to excessive load when lifting heavy flywheel assemblies, thus extending the service life of the lifting device.

[0032] When it is necessary to lift the flywheel assembly from the small press, first tie the flywheel assembly together, then use a hoist to connect the flywheel assembly to the pulley 4, and then pull the pulley 4 to slowly lift the flywheel assembly away from the small press. After it is completely lifted away, use a hoist to put the flywheel assembly on the ground.
