Description

Technical Field

[0001] This utility model belongs to the field of crane technology, specifically the end beam of a high-load-bearing European-style crane. Background Technology

[0002] The end beam of a European-style crane is an important component of the crane bridge structure, primarily bearing the weight of the main beam and the load being lifted, and serving to support and guide the crane's movement. It spans across rails at both ends of the factory building, enabling lifting and lowering. The trolley can travel along the load-bearing main beam, while the main beam can travel longitudinally along the side rails, utilizing the space below for material handling. Existing European-style crane end beams typically use rectangular tubing as the main material, making maintenance of the traveling mechanism relatively cumbersome.

[0003] The relevant reference CN205838361U discloses an end beam structure for a European-style double-girder crane. The end of the end beam body is provided with an arc-shaped bearing seat, and the traveling device is fixed by bolt holes through the arc-shaped bearing seat. The open bearing seat installation structure makes the design and manufacturing of the end beam body relatively complex. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a high-load European-style crane end beam that enables the crane to bear greater loads, has a simple design and manufacturing process for the end beam body, and is easy to maintain.

[0005] To solve the above technical problems, this utility model provides a high-load-bearing capacity European-style crane end beam, including an end beam body, which is mainly composed of two web plates and one end plate, forming a U-shape; an arc plate is provided on the end plate, and the top surface of the arc plate has a main beam platform, on which a base is fixedly installed; shaft holes are opened at both ends of the web plates, bearings are installed in the shaft holes, and rotating shafts pass through the bearings, with traveling wheels installed on the rotating shafts; one of the rotating shafts is installed on a reducer, and a rotary motor is installed on the reducer, with the rotary motor installed on the outer side of one of the web plates.

[0006] By adopting the above technical solution, the end beam body is designed in a U-shape, and an arc plate structure is set on the end plate. This effectively disperses stress, reduces stress concentration, and enables the crane to withstand greater loads, ensuring the crane's safety and stability during heavy-duty operations. The shaft holes are directly opened on the web plate, eliminating the need for complex open arc-shaped shaft seats on the end beam body. This simplifies the design and manufacturing of the end beam body, streamlines the installation, maintenance, and disassembly of the traveling wheels, facilitates inspection, and improves manufacturing efficiency.

[0007] Preferably, the arc plate is in the shape of a circular arch.

[0008] By adopting the above technical solutions, the arched design can more effectively distribute and transfer loads, providing better support for the main beam. Its excellent structural performance and load-bearing capacity extend the service life of the crane.

[0009] Preferably, the outer surface of the structure formed by the base, the arc plate, the two web plates and the end plate is covered with carbon fiber cloth.

[0010] By employing the above-mentioned technical solution, the carbon fiber cloth, bonded with a specialized adhesive, can significantly improve the load-bearing capacity of the end beam structure. Simultaneously, the carbon fiber cloth also possesses excellent durability and fatigue resistance, maintaining stability even in harsh environments and extending the service life of the end beam structure.

[0011] Preferably, a baffle is fixedly installed on the side of the arc plate.

[0012] By adopting the above technical solution, the baffle can provide additional support for the arched plate. When subjected to lateral force, the baffle can disperse and bear part of the pressure, thereby further enhancing the stability of the entire end beam structure.

[0013] Preferably, the outer surface of the structure formed by the base, the arc plate, the baffle, the two web plates and the end plate is covered with carbon fiber cloth.

[0014] By employing the above-mentioned technical solution, the carbon fiber cloth, bonded with a specialized adhesive, can significantly improve the load-bearing capacity of the end beam structure. Simultaneously, the carbon fiber cloth also possesses excellent durability and fatigue resistance, maintaining stability even in harsh environments and extending the service life of the end beam structure.

[0015] Preferably, the surface of the carbon fiber cloth is coated with a waterproof layer.

[0016] By adopting the above technical solution, the waterproof layer can effectively prevent water from penetrating the end beam structure through the carbon fiber cloth. The combination of carbon fiber cloth reinforcement and waterproof layer coating provides double protection for the end beam structure, which not only improves the load-bearing capacity, but also protects the end beam structure from water erosion, thereby extending the service life of the end beam structure.

[0017] Preferably, arc-shaped push plates are provided at both ends of the end beam body.

[0018] By adopting the above technical solutions, the arc-shaped push plate design allows for smoother sliding when pushing away debris compared to flat, right-angled, or V-shaped designs, thereby improving the stability and comfort of the end beam body running on the track.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model designs the end beam body into a gate shape and sets a circular arc plate on the end plate, which can effectively disperse stress, reduce stress concentration, enable the crane to bear greater loads, and ensure the safety and stability of the crane in heavy-duty operations.

[0021] 2. This utility model directly opens the shaft hole on the web plate, eliminating the need to specially set a complex open arc-shaped shaft seat on the end beam body. The design and manufacturing of the end beam body is simple, which simplifies the installation, maintenance and disassembly process of the traveling wheel and improves production efficiency.

[0022] 3. Compared with flat, right-angled, or V-shaped push plates, the arc-shaped push plate of this utility model allows for smoother sliding when pushing away debris, thereby improving the stability and comfort of the end beam body running on the track. Attached Figure Description

[0028] like Figure 1 and 2 As shown, the end beam of a high-load-bearing European-style crane includes the end beam body 1, which is mainly composed of two web plates 2 and one end plate 3. Figure 3 As shown, the two web plates 2 and the end plates 3 form a U-shape, and each web plate 2 has two shaft holes 7. Figure 4As shown, an arc plate 4 is provided on the end plate 3. A section of the arc plate 4 is cut off horizontally to form the main beam platform 5. A base 6 is fixedly installed on the main beam platform 5. A bearing 8 is installed in the shaft hole 7, and a rotating shaft 9 passes through the bearing 8. A retaining ring groove is provided at the end of the rotating shaft 9, and a shaft retaining ring is installed in the retaining ring groove. The retaining ring fits against the end face of the bearing 8 (not shown in the figure) and is used to prevent the rotating shaft 9 from moving axially. A traveling wheel 10 is installed on the rotating shaft 9. One of the rotating shafts 9 is slightly longer and has a keyway at the end that protrudes from the web plate 2. This rotating shaft 9 is installed in the rotating shaft hole of the reducer 11 by a key. A rotary motor 12 is installed on the reducer 11, and the rotary motor 12 is installed on the outer side of one of the web plates 2. This application designs the end beam body 1 as a portal frame and provides an arc plate 4 on the end plate 3. This structure can effectively disperse stress, reduce stress concentration, enable the crane to bear greater loads, and ensure the safety and stability of the crane in heavy-duty operations. The shaft hole 7 is directly opened on the web plate 2, eliminating the need to specially set a complex open arc-shaped shaft seat on the end beam body. The design and manufacturing of the end beam body is simple, which simplifies the installation, maintenance and disassembly process of the traveling wheel, makes maintenance convenient, and improves production efficiency.

[0029] Arc-shaped push plates 14 are respectively installed at both ends of the end beam body 1. Compared with flat, right-angled, or V-shaped push plates, the arc-shaped push plates can slide more smoothly when pushing away debris, thereby improving the stability and comfort of the end beam body running on the track. The straight edge of the push plate 14 is directly installed on the end face of the web plate 2.

[0030] like Figure 4 As shown, the arc plate 4 is in the shape of a circular arch. The circular arch design can more effectively distribute and transfer the load, providing better support for the main beam. Its excellent structural performance and load-bearing capacity extend the service life of the crane.

[0031] The structure formed by the base 6, the arc plate 4, the two web plates 2, the end plate 3, and the push plate 14 is covered with carbon fiber cloth. The carbon fiber cloth is bonded using a specialized adhesive, which significantly improves the load-bearing capacity of the end beam structure. Simultaneously, the carbon fiber cloth also possesses excellent durability and fatigue resistance, maintaining stability in harsh environments and extending the service life of the end beam structure.

[0032] A waterproof layer is coated on the surface of the carbon fiber cloth. The waterproof layer effectively prevents moisture from penetrating the end beam structure through the carbon fiber cloth. The combination of carbon fiber cloth reinforcement and waterproof coating provides double protection for the end beam structure, eliminating the need for painting the end beam structure. This not only improves the load-bearing capacity but also protects the end beam structure from water erosion, thereby extending the service life of the end beam structure.

[0033] During assembly, the end beam body 1 and the arc plate 4 are welded together. The base 6 is welded to the top surface of the arc plate 4. Then, carbon fiber cloth is pasted onto the surface of the structural plates, and a waterproof layer is applied. The traveling wheel 10 is placed in the shaft hole 7, and the rotating shaft 9 passes through the shaft hole 7 and the traveling wheel 10. The rotating shaft 9 and the traveling wheel 10 are limited by a key. The bearing 8 and the rotating shaft 9 are coaxial. The bearing 8 is hammered into the shaft hole 7 and installed in place with the rotating shaft 9. The end of the slightly longer rotating shaft 9 that protrudes from the web plate 2 has a keyway and is connected to the reducer 11. A rotary motor 12 is installed on the reducer 11. Finally, the main beam is bolted to the base 6. The rotary motor 12 is started, and the end beam of this application begins to move on the track. Example 2

[0034] like Figure 1 and 2 As shown, the end beam of a high-load-bearing European-style crane includes the end beam body 1, which is mainly composed of two web plates 2 and one end plate 3. Figure 3 As shown, the two web plates 2 and the end plates 3 form a U-shape, and each web plate 2 has two shaft holes 7. Figure 4 As shown, an arc plate 4 is provided on the end plate 3. A section of the arc plate 4 is cut off horizontally to form a main beam platform 5. A base 6 is fixedly installed on the main beam platform 5. A bearing 8 is installed in the shaft hole 7, and a rotating shaft 9 passes through the bearing 8. A retaining ring groove is provided at the end of the rotating shaft 9, and a shaft retaining ring is installed in the retaining ring groove. The retaining ring fits against the end face of the bearing 8 (not shown in the figure) and is used to prevent axial movement of the rotating shaft 9. A traveling wheel 10 is installed on the rotating shaft 9. One of the rotating shafts 9 is slightly longer and has a keyway at the end that protrudes from the web plate 2. This rotating shaft 9 is installed in the rotating shaft hole of the reducer 11 by a key. A rotary motor 12 is installed on the reducer 11, and the rotary motor 12 is installed on the outer side of one of the web plates 2.

[0035] A baffle 13 is fixedly installed on the side of the arc plate 4. The baffle 13 provides additional support for the arc plate 4. This application designs the end beam body 1 as a U-shape, and the structure of the arc plate 4 on the end plate 3 effectively disperses stress, reduces stress concentration, and allows the crane to withstand greater loads, ensuring the crane's safety and stability during heavy-duty operations. The baffle 13 provides additional support for the arc plate 4; when subjected to lateral forces, the baffle 13 can disperse and bear some of the pressure, thereby further enhancing the stability of the entire end beam structure. The shaft hole 7 is directly opened on the web plate 2, eliminating the need for a complex open arc-shaped shaft seat on the end beam body. This simplifies the design and manufacturing of the end beam body, simplifying the installation, maintenance, and disassembly of the traveling wheels, facilitating inspection, and improving manufacturing efficiency.

[0036] like Figure 4As shown, the arc plate 4 is in the shape of a circular arch. The circular arch design can more effectively distribute and transfer the load, providing better support for the main beam. Its excellent structural performance and load-bearing capacity extend the service life of the crane.

[0037] Arc-shaped push plates 14 are respectively installed at both ends of the end beam body 1. Compared with flat, right-angled, or V-shaped push plates, the arc-shaped push plates can slide more smoothly when pushing away debris, thereby improving the stability and comfort of the end beam body running on the track. The straight edge of the push plate 14 is directly installed on the end face of the web plate 2.

[0038] The structure formed by the base 6, the arc plate 4, the baffle 13, the two web plates 2, the end plate 3, and the push plate 14 is covered with carbon fiber cloth. The carbon fiber cloth is bonded using a special adhesive, which significantly improves the load-bearing capacity of the end beam structure. Simultaneously, the carbon fiber cloth also possesses excellent durability and fatigue resistance, maintaining stability in harsh environments and extending the service life of the end beam structure.

[0039] A waterproof layer is coated on the surface of the carbon fiber cloth. The waterproof layer effectively prevents moisture from penetrating the end beam structure through the carbon fiber cloth. The combination of carbon fiber cloth reinforcement and waterproof coating provides double protection for the end beam structure, eliminating the need for painting the end beam structure. This not only improves the load-bearing capacity but also protects the end beam structure from water erosion, thereby extending the service life of the end beam structure.

[0040] During assembly, the end beam body 1 and the arc plate 4 are welded together. A baffle 13 is welded to the side of the arc plate 4, and a base 6 is welded to the top surface of the arc plate 4. The two straight edges of the push plate 14 are welded to the ends of the two web plates 2 on the same side. Then, carbon fiber cloth is pasted onto the surface of the structural plates, and a waterproof layer is applied. The traveling wheel 10 is placed in the shaft hole 7, and the rotating shaft 9 passes through the shaft hole 7 and the traveling wheel 10. The rotating shaft 9 and the traveling wheel 10 are limited by a key. The bearing 8 and the rotating shaft 9 are coaxial. A hammer is used to drive the bearing 8 into the shaft hole 7 and into place with the rotating shaft 9. The slightly longer rotating shaft 9 has a keyway at its end protruding from the web plate 2 and connects to the reducer 11. A rotary motor 12 is installed on the reducer 11. Finally, the main beam is bolted to the base 6. The rotary motor 12 is started, and in this embodiment, the end beam begins to move on the track. This application increases the structural strength of the end beam and provides greater load-bearing capacity.
