Description

Technical Field

[0001] This utility model belongs to the field of crane construction technology, specifically relating to a crane anti-collision alarm device. Background Technology

[0002] Crane anti-collision alarm devices are safety systems designed to prevent cranes from colliding with surrounding objects (such as buildings, other lifting equipment, and goods) during operation through real-time monitoring and early warning mechanisms, thereby protecting the safety of the crane itself, the goods, and the surrounding environment. The working principle of crane anti-collision alarm devices is mainly based on real-time monitoring and data analysis of the crane's operating status.

[0003] However, traditional devices lacking anti-collision buffer mechanisms cannot effectively mitigate the impact force when a collision occurs, which may cause serious damage to cranes, goods and surrounding facilities, or even cause personal injury or death. Devices without alarm functions cannot provide timely warnings before or during a collision, making it difficult for operators and people around to take timely evasive or emergency braking measures, increasing the possibility and severity of accidents.

[0004] Therefore, a crane anti-collision alarm device is designed to solve the above problems. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides a crane anti-collision alarm device. By absorbing some of the impact energy through anti-collision components, it reduces or avoids direct damage to the crane itself, the hoisted object, or surrounding facilities. This not only protects expensive equipment from damage but also prevents downtime and increased maintenance costs due to equipment malfunctions. The alarm triggering device immediately issues an alarm when a potential collision risk is detected or a collision actually occurs, reminding operators to take timely measures to prevent the accident from escalating. This instant feedback mechanism significantly enhances the safety awareness of operators and reduces the accident rate caused by human negligence. In the crane operation environment, personnel safety is paramount. The presence of anti-collision components effectively reduces the risk of collisions between the crane and personnel, protecting on-site workers from injury. Simultaneously, the timely audible alarm from the alarm triggering device guides personnel to quickly evacuate to a safe area, thereby reducing equipment damage and maintenance time caused by collisions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a crane anti-collision alarm device, including a connector and an anti-collision component disposed on the outer side of the end of the connector;

[0007] The anti-collision assembly includes a first rotating arm, a second rotating arm, and a connecting frame. Two first rotating arms are rotatably connected to one side of the connecting member, and a second rotating arm is rotatably connected to the outer end of the first rotating arm. A connecting frame is fixedly connected to one side of the connecting member. The outer end of the second rotating arm is slidably connected to the inner side of the connecting frame. The outer ends of the two springs are fixedly connected to the outer ends of the two second rotating arms, respectively. A slider is rotatably connected to the inner end of the second rotating arm, and a top plate is slidably connected to one side of the slider.

[0008] As a preferred embodiment of the crane anti-collision alarm device of this utility model, an alarm triggering device is installed on one side of the connecting frame, and one end of the alarm triggering device is fixedly connected to one side of the top plate.

[0009] As a preferred embodiment of the crane anti-collision alarm device of this utility model, two hydraulic buffer rods are installed on one side of the connecting frame, and the outer side of the end of the hydraulic buffer rod is fixedly connected to one side of the top plate.

[0010] As a preferred embodiment of the crane anti-collision alarm device of this utility model, an anti-collision box is fixedly connected to one side of the top plate.

[0011] As a preferred embodiment of the crane anti-collision alarm device of this utility model, a plurality of anti-collision wheels are rotatably connected to the inner side of the end of the anti-collision box, and the anti-collision wheels are made of rubber.

[0012] As a preferred embodiment of the crane anti-collision alarm device of this utility model, the anti-collision box has a fan-shaped structure and is made of carbon fiber.

[0013] As a preferred embodiment of the crane anti-collision alarm device of this utility model, anti-collision strips are fixedly connected to both outer ends of the top plate, and the anti-collision strips are made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The addition of anti-collision components absorbs some of the impact energy, thereby reducing or avoiding direct damage to the crane itself, the hoisted object, or surrounding facilities. This not only protects expensive equipment from damage but also avoids downtime and increased maintenance costs due to equipment malfunctions. The alarm triggering device can immediately issue an alarm when a potential collision risk is detected or a collision actually occurs, reminding operators to take timely measures to prevent the accident from escalating. This instant feedback mechanism can significantly enhance the safety awareness of operators and reduce the accident rate caused by human negligence. In the crane operation environment, personnel safety is paramount. The presence of anti-collision components can effectively reduce the risk of collisions between the crane and personnel, protecting on-site workers from injury. Simultaneously, the timely alarm sound from the alarm triggering device can guide personnel to quickly evacuate to a safe area, thereby reducing equipment damage and maintenance time caused by collisions.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] like Figure 1 As shown;

[0026] A crane anti-collision alarm device includes a connector 1.

[0027] In this implementation plan: However, traditional devices lacking anti-collision buffer mechanisms cannot effectively mitigate impact forces when a collision occurs, which may cause serious damage to cranes, goods and surrounding facilities, or even cause personal injury or death. Devices without intelligent alarm functions cannot provide timely warnings before or during a collision, making it difficult for operators and surrounding personnel to take timely avoidance or emergency braking measures, increasing the possibility and severity of accidents. To solve this technical problem, anti-collision component 2 is added on this basis.

[0028] Furthermore:

[0029] like Figures 1 to 5 As shown:

[0030] Based on the above: the anti-collision component 2 includes a first rotating arm 21, a second rotating arm 22, and a connecting frame 23. Two first rotating arms 21 are rotatably connected to one side of the connector 1. The second rotating arm 22 is rotatably connected to the outer side of the end of the first rotating arm 21. The connecting frame 23 is fixedly connected to one side of the connector 1. The outer side of the end of the second rotating arm 22 is slidably connected to the inner side of the connecting frame 23. The outer sides of both ends of the spring 24 are fixedly connected to the outer sides of the ends of the two second rotating arms 22 respectively. A slider 211 is rotatably connected to the inner side of the end of the second rotating arm 22. A top plate 25 is slidably connected to one side of the slider 211. An alarm triggering device 26 is installed on one side of the connecting frame 23. The outer side of one end of the alarm triggering device 26 is fixedly connected to one side of the top plate 25. The anti-collision box 28 has a fan-shaped structure and is made of carbon fiber. Anti-collision strips 210 are fixedly connected to the outer sides of both ends of the top plate 25. The anti-collision strips 210 are made of rubber.

[0031] In this implementation scheme: When using the device, the user can fix it to the front of the crane or the load-bearing arm via the connector 1. Upon collision, the top plate 25 will be compressed. Under the action of the top plate 25, the second rotating arm 22 will push the slider 211 to slide on one side of the top plate 25. Simultaneously, the other end of the second rotating arm 22 will slide inside the connecting frame 23. The ends of both second rotating arms 22 will simultaneously compress towards the center, compressing the spring 24 and storing elastic potential energy. This will also compress the alarm triggering device 26. When the alarm triggering device 26 is compressed to a certain extent, it will trigger the alarm system. Meanwhile, the anti-collision strip 210 can increase the anti-collision range of the device, further increasing its practicality. By absorbing some of the impact energy through the anti-collision component 2, direct damage to the crane itself, the suspended object, or surrounding facilities can be reduced or avoided. This not only protects the expensive crane... The device protects equipment from damage and avoids downtime and increased maintenance costs due to equipment failure. The alarm triggering device 26 can immediately issue an alarm when a potential collision risk is detected or a collision actually occurs, reminding operators to take timely measures to prevent the accident from escalating. This instant feedback mechanism can significantly enhance the safety awareness of operators and reduce the accident rate caused by human negligence. In the lifting operation environment, personnel safety is of paramount importance. The presence of the anti-collision component 2 can effectively reduce the risk of collision between the crane and personnel, protecting on-site workers from injury. At the same time, the timely alarm sound of the alarm triggering device 26 can also guide personnel to quickly evacuate to a safe area. By reducing equipment damage and maintenance time caused by collisions and avoiding downtime caused by accidents, this device indirectly improves the efficiency and continuity of lifting operations. Reducing unexpected downtime means more production time and lower operating costs.

[0032] Furthermore:

[0033] In an optional embodiment, a crash box 28 is fixedly connected to one side of the top plate 25, and a plurality of crash wheels 29 are rotatably connected to the inner side of the end of the crash box 28. The crash wheels 29 are made of rubber.

[0034] In this implementation plan, integrating the anti-collision box 28 and anti-collision wheel 29 into the crane anti-collision alarm device can bring multiple significant benefits. As flexible contact components, the anti-collision box 28 and anti-collision wheel 29 can form a buffer zone between the crane and the obstacle, effectively reducing the impact force during collision, thereby further protecting the crane itself, the hoisted object and surrounding facilities from direct impact damage. Secondly, the anti-collision wheel 29 will rotate to a certain extent when it is hit by a collision, which can further absorb the impact force generated during the collision.

[0035] Furthermore:

[0036] In an optional embodiment, two hydraulic buffer rods 27 are installed on one side of the connecting frame 23, and the outer ends of the hydraulic buffer rods 27 are fixedly connected to one side of the top plate 25.

[0037] In this implementation plan, installing two hydraulic buffer bars 27 in the crane anti-collision alarm device can bring many significant advantages. With its excellent energy absorption capacity, the hydraulic buffer bar 27 can effectively reduce the impact when a collision occurs, thereby greatly reducing the damage to the crane structure, the suspended object and the surrounding environment.

[0038] Working principle: When using this device, the user can fix it to the front of the crane or the load-bearing arm via the connector 1. Upon collision, the top plate 25 will be compressed. Under the action of the top plate 25, the second rotating arm 22 will push the slider 211 to slide on one side of the top plate 25. Simultaneously, the other end of the second rotating arm 22 will slide inside the connecting frame 23. The ends of both second rotating arms 22 simultaneously compress towards the center, compressing the spring 24 and storing elastic potential energy. This also compresses the alarm trigger device 26. When the alarm trigger device 26 is compressed to a certain extent, it will trigger the alarm system, simultaneously preventing collisions. Clause 210 can increase the collision protection range of the device, further enhancing its practicality. By absorbing some of the impact energy through the collision protection component 2, direct damage to the crane itself, the hoisted object, or surrounding facilities can be mitigated or avoided. This not only protects expensive equipment from damage but also prevents downtime and increased maintenance costs due to equipment malfunctions. The alarm triggering device 26 can immediately issue an alarm when a potential collision risk is detected or a collision actually occurs, reminding operators to take timely measures to prevent the accident from escalating. This instant feedback mechanism can significantly enhance the safety awareness of operators and reduce the accident rate caused by human negligence in the lifting operation environment. Personnel safety is paramount. The presence of the anti-collision component 2 effectively reduces the risk of collisions between the crane and personnel, protecting on-site workers from injury. Simultaneously, the timely alarm sound triggered by the alarm trigger device 26 guides personnel to a safe area. By reducing equipment damage and repair time caused by collisions, and avoiding downtime due to accidents, this device indirectly improves the efficiency and continuity of crane operations. Reduced unexpected downtime translates to more production time and lower operating costs. Integrating the anti-collision box 28 and anti-collision wheel 29 into the crane anti-collision alarm device offers multiple significant benefits. As a flexible contact component, the impact wheel 29 can form a buffer zone between the crane and the obstacle, effectively reducing the impact force during the collision, thereby further protecting the crane itself, the hoisted object and surrounding facilities from direct impact damage. Secondly, the impact wheel 29 will rotate to a certain extent when it is hit by a collision, which can further absorb the impact force generated during the collision. Installing two hydraulic buffer bars 27 in the crane anti-collision alarm device can bring many significant advantages. With its excellent energy absorption capacity, the hydraulic buffer bar 27 can effectively reduce the impact when a collision occurs, thereby greatly reducing the damage to the crane structure, the hoisted object and the surrounding environment.
