Description

Technical Field

[0001] This utility model relates to the field of safety and collision avoidance technology, and in particular to a bridge crane that can safely avoid collisions. Background Technology

[0002] With the acceleration of industrialization, cranes, as a common lifting equipment, are widely used in construction, ports, manufacturing, and other fields. However, during crane lifting, the lifting and lowering of goods, coupled with gravity, can subject cranes to impact forces, leading to equipment damage and reduced stability, thus affecting work efficiency and safety. Therefore, improving the service life and stability of cranes has become an important direction for current technological research and development. To address this issue, the bridge crane design has emerged. It possesses strong load-bearing capacity and stability. Through a rationally designed mechanical structure and anti-collision devices, it can effectively reduce the negative impacts of external impacts, thereby improving the overall performance of the crane and ensuring safety and reliability during lifting operations.

[0003] Currently, existing cranes typically rely on traditional mechanical structures to support heavy objects and complete lifting tasks. Existing technologies mainly consist of basic components such as steel cables, hydraulic systems, and steel beams, combined with the crane's power system for operation. Hydraulic systems are often used to lift or lower loads, and steel cables are used to traction and lift goods.

[0004] In the existing technology, although some crane equipment is equipped with basic shock absorption devices, it is still not possible to effectively solve the problem of damage to the crane structure caused by the impact force of gravity inertia during the hoisting process. Especially when the equipment reaches the limit position, the inertial force and impact force will directly act on the core components of the crane, causing damage to the equipment structure or even failure. This impact force not only affects the service life of the equipment, but also poses a threat to the operators and the surrounding environment. Therefore, a safe and collision-resistant bridge crane is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a safe and collision-resistant bridge crane, including a sliding frame, a traction component is provided inside the sliding frame, energy-absorbing components are provided on both the left and right sides of the sliding frame, a support component is provided below the energy-absorbing components, and both the left and right sides of the sliding frame are slidably connected to the top of the support component.

[0007] The energy-absorbing component includes a hollow frame and a baffle. The baffle is slidably connected inside the hollow frame.

[0018] As a further description of the above technical solution:

[0019] The side support assembly includes a rotating frame one and a rotating frame two, both of which are rotatably connected to the outer wall of the support frame.

[0020] As a further description of the above technical solution:

[0021] A hydraulic rod is rotatably connected to the outer wall of the support frame, and a support frame is fixedly connected to the output end of the hydraulic rod. The support frame is rotatably connected inside the rotating frame one and the rotating frame two, and a chassis is fixedly connected to the bottom of the support frame.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the support platform slides left and right on the sliding frame, it will impact both sides of the sliding frame when it reaches the maximum limit.

[0031] 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.

[0032] Reference Figure 1 - Figure 3 An embodiment of this utility model is provided: a safe and collision-proof bridge crane, including a sliding frame 4, a traction component is provided inside the sliding frame 4, energy absorption components are provided on both the left and right sides of the sliding frame 4, a support component is provided below the energy absorption components, and the left and right sides of the sliding frame 4 are slidably connected to the top of the support component.

[0033] The energy-absorbing assembly includes a hollow frame 11 and a baffle 15. The baffle 15 is slidably connected inside the hollow frame 11. A fixing component is provided on the outer wall of the hollow frame 11, and the bottom of the fixing component is fixedly connected to the top of the sliding frame 4. Telescopic columns 12 are symmetrically arranged inside the hollow frame 11. One end of the telescopic column 12 is fixedly connected to the inner wall of the hollow frame 11, and the other end of the telescopic column 12 is fixedly connected to the inner wall of the baffle 15. The function of the telescopic column 12 is to mitigate the impact and reduce the transmission of inertial force when the energy-absorbing assembly is subjected to impact force, thereby avoiding serious damage to the crane structure. A damping device is provided inside the hollow frame 11. The damper 14 and spring 13 are fixedly connected at one end to the center of the inner wall of the hollow frame 11. One end of the spring 13 is fixedly connected to the side wall of the baffle 15, and the output end of the damper 14 is fixedly connected to the side wall of the baffle 15. The function of the spring 13 and the damper 14 is to provide buffering and shock absorption. When the sliding frame 4 reaches its maximum limit, the spring 13 can provide a certain reaction force through elastic restoring force, while the damper 14 absorbs the impact energy to further reduce the impact speed of the baffle 15, ensuring that the entire energy absorption assembly can smoothly and effectively disperse the impact force and protect the crane from damage.

[0034] Reference Figure 1 - Figure 4The fixing component includes a fixing block 16, the inner wall of which is fixedly connected to the outer wall of the hollow frame 11. A fixing plate 6 is fixedly connected to the side wall of the fixing block 16, and the bottom of the fixing plate 6 is fixedly connected to the top of the sliding frame 4. The function of the fixing component is to stably connect the hollow frame 11 and the sliding frame 4 together, ensuring the overall stability of the structure and providing fixed support for the traction component. The fixing block 16 plays a supporting and fixing role, allowing the sliding frame 4 to slide reliably within the hollow frame 11 and preventing structural displacement. The traction component includes a support platform 5, which is slidably connected to the top of the sliding frame 4. A motor 7 is fixedly connected to the top of the support platform 5, and the output end of the motor 7 is fixedly connected to the top of the support platform 5. A rotating column 8 is fixedly connected, and a steel wire rope 9 is sleeved on the outer wall of the rotating column 8. One end of the steel wire rope 9 is fixedly connected to a hook 10. The function of the traction assembly is to drive the rotating column 8 to rotate through the motor 7, thereby driving the movement of the steel wire rope 9. The hook 10 is used for lifting or traction of objects. The motor 7 provides power support. The cooperation between the rotating column 8 and the steel wire rope 9 enables the hook 10 to achieve precise lifting and placement when needed. The support assembly includes a slide rail 3, a sliding frame 4 slidably connected to the top of the slide rail 3, a support frame 2 fixedly connected to the bottom of the slide rail 3, and a base 1 fixedly connected to the bottom of the support frame 2. The function of the support assembly is to provide a stable sliding track for the sliding frame 4. To ensure smooth movement of the sliding frame 4 and prevent jamming or instability, the support frame 2 and the base 1 together form a stable support foundation for the entire device, ensuring that the structure is not prone to tilting or collapse. Side support assemblies are provided on both outer walls of the support frame 2. These side support assemblies include a rotating frame 18 and a rotating frame 2 19, both rotatably connected to the outer walls of the support frame 2. The function of the side support assemblies is to provide additional support force through the rotation of the rotating frames 18 and 2 19, enhancing the stability of the overall structure. Through these rotating frames, the side support assemblies can adjust the support angle as needed, ensuring the device can operate smoothly in different working environments. To maintain balance, a hydraulic rod 17 is rotatably connected to the outer wall of the support frame 2. A support frame 20 is fixedly connected to the output end of the hydraulic rod 17. The support frame 20 is rotatably connected inside the rotating frame 18 and the rotating frame 29. A chassis 21 is fixedly connected to the bottom of the support frame 20. The function of the hydraulic rod 17 is to adjust the position and angle of the support frame 20 by controlling the extension and retraction of the output end, thereby optimizing the support effect of the entire device. Driven by the hydraulic rod 17, the support frame 20 can rotate freely between the rotating frame 18 and the rotating frame 29. The chassis 21 provides a more stable support foundation.

[0035] Working principle: When using a bridge crane for cargo lifting, as the support platform 5 slides on the sliding frame 4, the weight of the cargo causes the support platform 5 to generate an inertial impact force that strikes both sides of the crane. At this time, the support platform 5 contacts the baffle 15, causing the baffle 15 to slide inside the hollow frame 11. During the sliding process, the baffle 15 compresses the telescopic column 12 and the spring 13. Simultaneously, the damper 14 moves synchronously with the spring 13. Subsequently, the damper 14 controls the rebound speed of the spring 13, thereby... This achieves the purpose of buffering the impact force generated during the crane hoisting process. At the same time, during the crane hoisting process, the crane bridge swayed due to the large weight of the goods. This caused the support frame 20 to rotate by activating the output end of the hydraulic rod 17. During the rotation of the support frame 20, the rotating frame 18 and the rotating frame 29 also rotated. By adjusting the angles of the rotating frame 18, the rotating frame 29 and the support frame 20, the chassis 21 was finally supported on the ground, thus achieving the purpose of side wall support for the crane bridge.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
