Description

Technical Field

[0001] This utility model belongs to the technical field of lifting equipment, specifically a crane end beam anti-collision device. Background Technology

[0002] The end beam is a structural component of a bridge crane. Its main function is to bear the load of the main beam and move along the track. Bridge cranes are typically used inside workshops and warehouses, with their running tracks adjacent to the building walls. During operation, bridge cranes need to maintain a certain level of stability. If not controlled in time, the running speed is too high, or the brakes fail, the end beam may collide with the wall. This collision can cause damage to the end beam, such as deformation, and may even damage the track and wheel bearings. Damaged components require shutdown for replacement or repair, impacting production efficiency.

[0003] The relevant reference CN205855816U discloses a crane end beam anti-collision device. The anti-collision device is fixed on a mounting base, with a fixed sleeve connected to the middle of the outer side of the mounting base. A hydraulic cylinder is installed inside the fixed sleeve, with a piston rod at the top. A slide rail is arranged around the outer side of the fixed sleeve, and a sliding sleeve is arranged around the outer side of the slide rail. A slider matching the slide rail is installed inside the sliding sleeve, and an anti-collision cap is installed at the top of the sliding sleeve. The hydraulic cylinder neutralizes the collision force transmitted from the anti-collision cap. The hydraulic cylinder requires a complete hydraulic system, including a hydraulic pump, hydraulic tank, hydraulic lines, and related control valves. These components not only increase the complexity of the system but also increase the difficulty of installation and maintenance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a crane end beam anti-collision device that significantly reduces the impact of collisions on the end beam, protects the crane structure from damage, and is easy to install and maintain.

[0005] To solve the above technical problems, this utility model provides a crane end beam anti-collision device, including a fixed sleeve and a sliding sleeve. The fixed sleeve is installed on a positioning seat. A spring cavity and a silicone damper are installed inside the fixed sleeve. The silicone damper is located in the center, and the spring cavity is located around the silicone damper. Both the spring cavity and the silicone damper are fixed on the positioning seat. A slide rail is axially symmetrically arranged on the outer wall of the fixed sleeve. A slide groove is provided on the inner wall of the sliding sleeve. The slide rail slides in the slide groove. An anti-detachment ring is provided at the end of the fixed sleeve. An anti-detachment step is provided on the inner wall of the sliding sleeve. The anti-detachment ring is locked by the anti-detachment step. A second spring cavity is installed on the inner bottom surface of the sliding sleeve. The first spring cavity and the second spring cavity are connected together by an alloy spring.

[0006] By adopting the above technical solution, a silicone damper serves as the main anti-collision component, surrounded by alloy springs. This results in a relatively simple structure and reduced maintenance difficulty. When the end beam collides, the sliding sleeve slides inward along the fixed sleeve via a guide rail. While the silicone damper directly absorbs and dissipates the impact energy through physical deformation, the alloy springs provide stable rebound energy. Both work together to withstand the impact, enabling the anti-collision device to better cope with collisions, significantly reducing the impact on the crane's end beam and protecting the crane structure from damage.

[0007] Preferably, the spring cavities are multiple springs that are evenly distributed circumferentially.

[0008] By adopting the above technical solution, the alloy spring is fixed by the spring cavity, preventing the alloy spring from shifting when it is impacted.

[0009] Preferably, the spring cavity 2 is a plurality of spring cavities evenly distributed in the circumference.

[0010] By adopting the above technical solution, the alloy spring is fixed by the spring cavity, preventing the alloy spring from shifting when it is impacted.

[0011] Preferably, the alloy springs are multiple springs that are evenly distributed circumferentially.

[0012] By adopting the above technical solution, the coordinated operation of multiple alloy springs can significantly improve the buffering capacity of the anti-collision device, so that the impact energy can be better absorbed and dispersed.

[0013] Preferably, the sliding sleeve consists of two halves assembled together, with positioning holes provided on the assembly surface of one half of the sliding sleeve and positioning posts provided on the assembly surface of the other half of the sliding sleeve.

[0014] By adopting the above technical solution, the design of the positioning post and positioning hole enables the two halves of the sliding sleeve to be positioned quickly and accurately during assembly, thereby improving assembly efficiency.

[0015] Preferably, a crash plate is installed at the top of the sliding sleeve, and a crash protrusion is fixedly installed on the crash plate.

[0016] By adopting the above technical solution, the anti-collision protrusion and the anti-collision plate are assembled together and then installed on the top of the sliding sleeve. The installation is convenient, and the anti-collision protrusion can absorb and disperse energy during impact, reducing the impact on the sliding sleeve.

[0017] Preferably, the anti-collision protrusion is a silicone block.

[0018] By adopting the above technical solution, the silicone block anti-collision protrusion has excellent elasticity and can quickly return to its original shape after being subjected to force. This characteristic enables the silicone block anti-collision protrusion to effectively absorb and disperse external impact force, protecting the impacted object from damage.

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

[0020] 1. This utility model uses a silicone damper as the main anti-collision component, surrounded by an alloy spring. The structure is relatively simple, reducing maintenance difficulty. When the end beam collides, the sliding sleeve slides inward along the fixed sleeve via a slide rail. While the silicone damper directly absorbs and dissipates the impact energy through physical deformation, the alloy spring provides stable rebound energy. Both components work together to withstand the impact, enabling the anti-collision device to better cope with collisions, significantly reducing the impact on the crane's end beam and protecting the crane structure from damage.

[0021] 2. This utility model relates to two sliding sleeves assembled in halves. One half of the sliding sleeve has a positioning hole on its assembly surface, and the other half has a positioning post on its assembly surface. The design of the positioning post and positioning hole enables the two halves of the sliding sleeve to be positioned quickly and accurately during assembly, improving assembly efficiency.

[0022] 3. The multiple alloy springs of this invention can work together to significantly improve the buffering capacity of the anti-collision device, so that the impact energy is better absorbed and dispersed. Attached Figure Description

[0031] Example 1

[0032] like Figure 4 As shown, the crane end beam anti-collision device includes a fixed sleeve 1 and a sliding sleeve 2. The fixed sleeve 1 is mounted on the positioning seat 3, and a spring cavity 4 and a silicone damper 5 are installed inside the fixed sleeve 1. Figure 1 As shown, slide rails 6 are symmetrically arranged axially on the outer wall of the fixed sleeve 1; an anti-detachment ring 8 is provided at the end of the fixed sleeve 1. Figure 2 As shown, the sliding sleeve 2 consists of two halves assembled together. One half of the sliding sleeve 2 has a positioning hole 14 on its assembly surface, while the other half has a positioning post 15 on its assembly surface. The design of the positioning post 15 and the positioning hole 14 allows for quick and accurate positioning of the two halves of the sliding sleeve 2 during assembly, improving assembly efficiency. A groove 7 is provided on the inner wall of the sliding sleeve 2, and a spring cavity 10 is installed on the inner bottom surface of the sliding sleeve 2. The slide rail 6 slides within the groove 7. An anti-detachment step 9 is provided on the inner wall of the sliding sleeve 2; the anti-detachment ring 8 is held in place by the anti-detachment step 9.

[0033] like Figure 3 As shown, the silicone damper 5 is located in the center, and the spring cavity 4 is located around the silicone damper 5; both the spring cavity 4 and the silicone damper 5 are fixed on the positioning seat 3. The spring cavity 4 and the spring cavity 10 are connected together by an alloy spring 11.

[0034] Four spring cavities, numbered 4 and 10, are evenly distributed circumferentially. The alloy springs 11 are fixed within these cavities to prevent displacement upon impact. The four alloy springs 11 work together to significantly improve the buffering capacity of the anti-collision device, allowing impact energy to be better absorbed and dispersed.

[0035] This application uses a silicone damper 5 as the main anti-collision device, surrounded by an alloy spring 11. The structure is relatively simple, reducing maintenance difficulty. When the end beam collides, the sliding sleeve 2 slides inward along the fixed sleeve 1 via the slide rail 6. While the silicone damper 5 directly absorbs and dissipates the impact energy through physical deformation, the alloy spring 11 provides stable rebound energy. Both work together to withstand the impact, enabling the anti-collision device to better cope with collisions, significantly reducing the impact on the crane end beam and protecting the crane structure from damage.

[0036] During operation, the end beam moves on the track via traveling wheels, and anti-collision devices are installed at both ends of the end beam. When the end beam collides, the top surface of the sliding sleeve 2 is subjected to the impact force. The sliding sleeve 2 slides inward along the fixed sleeve 1 on the slide rail 6, and the top surface contacts the silicone damper 5 and the alloy spring 11. The silicone damper 5 rebounds under the force, dissipating the impact energy, while the alloy spring 11 provides stable rebound performance. The silicone damper 5 and the alloy spring 11 work together to withstand the impact, significantly improving the reliability of the anti-collision device's rebound after impact. In summary, this utility model significantly reduces the impact of collisions on the crane's end beam, protecting the crane structure from damage.

[0037] Example 2

[0038] like Figure 5 , 6 As shown, the crane end beam anti-collision device includes a fixed sleeve 1 and a sliding sleeve 2. The fixed sleeve 1 is mounted on the positioning seat 3, and a spring cavity 4 and a silicone damper 5 are installed inside the fixed sleeve 1. Figure 1 As shown, slide rails 6 are symmetrically arranged axially on the outer wall of the fixed sleeve 1; an anti-detachment ring 8 is provided at the end of the fixed sleeve 1. Figure 2 As shown, the inner wall of the sliding sleeve 2 is provided with a groove 7; the slide rail 6 slides in the groove 7; the inner wall of the sliding sleeve 2 is provided with an anti-detachment step 9; the anti-detachment ring 8 is stuck by the anti-detachment step 9; a second spring cavity 10 is installed on the inner bottom surface of the sliding sleeve 2. The first spring cavity 4 and the second spring cavity 10 are connected together by an alloy spring 11. The sliding sleeve 2 consists of two halves assembled together. One half of the sliding sleeve 2 has a positioning hole 14 for positioning on its assembly surface, and the other half of the sliding sleeve 2 has a positioning post 15 on its assembly surface. The design of the positioning post 15 and the positioning hole 14 enables the two halves of the sliding sleeve 2 to be positioned quickly and accurately during assembly, improving assembly efficiency.

[0039] like Figure 3 As shown, the silicone damper 5 is located in the center, and the spring cavity 4 is located around the silicone damper 5; both the spring cavity 4 and the silicone damper 5 are fixed on the positioning seat 3.

[0040] The spring cavities 4 are four in number, evenly distributed around the circumference. The alloy spring 11 is fixed in place by the spring cavities 4 to prevent it from shifting when subjected to impact.

[0041] The second spring cavity 10 consists of four circumferentially evenly distributed spring cavities. The alloy spring 11 is fixed by the second spring cavity 10 to prevent the alloy spring 11 from shifting when it is impacted.

[0042] Four alloy springs 11 are evenly distributed circumferentially. The coordinated operation of multiple alloy springs 11 can significantly improve the buffering capacity of the anti-collision device, allowing impact energy to be better absorbed and dispersed.

[0043] like Figure 7 As shown, a crash plate 12 is installed at the top of the sliding sleeve 2, and a crash protrusion 13 is fixedly installed on the crash plate 12. The crash protrusion 13 and the crash plate 12 are assembled together and then installed at the top of the sliding sleeve 2. The installation is convenient. The crash protrusion 13 can absorb and disperse energy during impact, reducing the impact on the sliding sleeve 2.

[0044] The anti-collision protrusion 13 is made of silicone. The silicone anti-collision protrusion 13 has excellent elasticity and can quickly return to its original shape after being subjected to force. This property allows the silicone anti-collision protrusion 13 to effectively absorb and disperse external impact forces, protecting the impacted object from damage.

[0045] This application uses a silicone damper 5 as the main anti-collision component, surrounded by an alloy spring 11. The structure is relatively simple, reducing maintenance difficulty. When the end beam collides, the sliding sleeve 2 slides inward along the fixed sleeve 1 via the slide rail 6. While the silicone damper 5 directly absorbs and dissipates the impact energy through physical deformation, the alloy spring 11 provides stable rebound energy. Both components work together to withstand the impact, enabling the anti-collision device to better cope with collisions and significantly reducing the impact on the crane end beam, protecting the crane structure from damage. The silicone block anti-collision protrusion 13 further enhances the anti-impact effect.

[0046] During operation, the end beam moves on the track via wheels, and this anti-collision device is installed at both ends of the end beam. When the end beam collides, the silicone anti-collision protrusion 13 on the anti-collision plate 12 first absorbs the force, and then the anti-collision plate 12 pushes the sliding sleeve 2 under the action of the collision force. The sliding sleeve 2 slides inward along the fixed sleeve 1 on the slide rail 6, and its top surface contacts the silicone damper 5 and the alloy spring 11. The silicone damper 5 rebounds under the force, dissipating the impact energy, while the alloy spring 11 provides stable rebound performance. The silicone damper 5 and the alloy spring 11 work together to withstand the impact, significantly improving the reliability of the anti-collision device's rebound. The silicone anti-collision protrusion 13 has excellent elasticity and can quickly return to its original shape after being subjected to force, further enhancing the impact resistance. In summary, this utility model significantly reduces the impact of collisions on the crane end beam and protects the crane structure from damage.
