Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and in particular to an anti-collision device for material handling machines. Background Technology

[0002] Material handling machines are widely used in many fields to realize the loading, unloading, transportation, lifting, stacking and storage of materials. The use of material handling machines can reduce labor intensity, reduce product damage, protect worker health, improve labor productivity and product quality, and reduce production costs.

[0003] Material handling machines may collide with other objects during operation, causing damage. Therefore, protection is necessary. Currently, common protective mechanisms are protective fences that shield the material handling machine, thus providing protection. However, these fences are bulky and inconvenient for loading and unloading materials. Furthermore, they do not provide adequate cushioning in the event of a collision, and both the protective mechanism and the material handling machine are prone to damage.

[0004] Therefore, to address the aforementioned problems of inconvenience in loading and unloading materials and insufficient buffering effect, anti-collision devices for material handling machines can be designed. Utility Model Content

[0005] This addresses the technical problems of inconvenience in loading and unloading materials and insufficient buffering effect.

[0006] The technical solution of this utility model is as follows: a material handling machine protective anti-collision device, including a base; and a magnetic buffer assembly. The upper end of the base is fixedly connected to a guide rail symmetrically distributed front and rear. The guide rail is equipped with a magnetic buffer assembly, which includes a first magnet and a second magnet. A guide post is inserted into the second magnet. A special shock-absorbing damping spring is installed on the outside of the guide post. A movable plate is fixedly connected to the lower ends of the second magnet and another second magnet. A spring damping shock absorber and a mounting seat are fixedly connected to the right end of the movable plate in sequence. A primary buffer seat is fixedly connected between the mounting seat and another mounting seat. Buffer rollers distributed at equal intervals are rotatably connected to the opening at the right end of the primary buffer seat. A buffer plate is fixedly connected to the right end of the base. Contact switches are fixedly connected to the recesses on both the front and rear sides of the right end of the base. A protrusion corresponding to each contact switch is fixedly connected to the left end of the movable plate.

[0007] Preferably, the base is installed around the material handling machine, and the contact switch is connected to the controller of the material handling machine to control the emergency stop of the material handling machine. When a collision occurs, the buffer roller in the first-stage buffer seat provides first-stage buffering of the force. If the force is large, after being buffered by the buffer roller, part of the force is transmitted to the spring damping shock absorber between the mounting base and another mounting base for second-stage buffering. Then, the spring damping shock absorber pushes the moving plate to the left, and the second magnet moves to the left along the direction of the guide column. The damping spring is compressed. At the same time, due to the attraction of the first and second magnets, it is more difficult for the second magnet to move, resulting in third-stage buffering. Finally, the moving plate hits the buffer plate, resulting in fourth-stage buffering. If all the force still cannot be eliminated, the moving plate continues to move, and the protrusion squeezes the contact switch. The contact switch enables the emergency stop operation of the material handling machine, thereby protecting the material handling machine.

[0008] Preferably, a shock-absorbing pad of the same width and height is fixedly connected to the left end of the base.

[0009] Preferably, the first magnet is fixedly connected to the lower top of the guide rail, and the first magnet and the second magnet are magnetically connected.

[0010] Preferably, the guide post is fixedly connected between the inner walls of the left and right sides of the guide rail, and the shock-absorbing damping spring is fixedly connected between the inner wall of the left side of the guide rail and the second magnet.

[0011] Preferably, the buffer roller is made of rubber, and the diameter of the buffer roller is larger than the opening width of the primary buffer seat.

[0012] Preferably, the buffer plate adopts an arc-shaped structure that protrudes to one side of the moving plate, and the length of the buffer plate is greater than half the length of the moving plate. The buffer plate is made of shape memory metal.

[0013] The beneficial effects of this utility model are as follows: It is equipped with a multi-stage buffer mechanism, which absorbs the force during impact in multiple stages, thereby preventing a large impact on the material handling machine and playing a good anti-collision protection role. This is crucial for extending the service life of the material handling machine and ensuring its integrity and safety. The multi-stage shock absorption structure can absorb the impact energy in stages, allowing the impact force to be dispersed and released over a longer period of time, effectively reducing the impact intensity on the material handling machine. Moreover, the overall size is small, and it can be installed around the material handling machine without affecting the loading and unloading of materials, making it convenient to use.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-4 This utility model provides an embodiment of an anti-collision device for material handling machine protection, including a base 1; it also includes a magnetic buffer assembly. The upper end of the base 1 is fixedly connected to a guide rail 2 symmetrically distributed front and rear. The guide rail 2 is provided with a magnetic buffer assembly, which includes a first magnet 31 and a second magnet 32. A guide post 33 is inserted into the second magnet 32. A special shock-absorbing damping spring 34 is installed on the outside of the guide post 33. The lower ends of the second magnet 32 ​​and another second magnet 32 ​​are fixedly connected to a movable plate 4. The right end of the movable plate 4 is sequentially fixedly connected to a spring damping shock absorber 5 and a mounting seat 6. A primary buffer seat 7 is fixedly connected between the mounting seat 6 and another mounting seat 6. The right end opening of the primary buffer seat 7 is rotatably connected to buffer rollers 8 distributed at equal intervals. The right end of the base 1 is fixedly connected to a buffer plate 9. The front and rear recesses of the right end of the base 1 are fixedly connected to contact switches 10. The left end of the movable plate 4 is fixedly connected to a protrusion 11 corresponding to the contact switches 10.

[0021] Please see Figures 2-3 In this embodiment, a shock-absorbing soft pad 12 of the same width and height is fixedly connected to the left end of the base 1. The first magnet 31 is fixedly connected to the lower end of the top of the guide rail 2. The first magnet 31 and the second magnet 32 ​​are magnetically connected to increase the resistance of the second magnet 32 ​​sliding in the guide rail 2, thereby effectively absorbing the force generated by the collision. The guide post 33 is fixedly connected between the inner walls of the left and right sides of the guide rail 2. The shock-absorbing damping spring 34 is fixedly connected between the inner wall of the left side of the guide rail 2 and the second magnet 32.

[0022] Please see Figure 2 and Figure 4In this embodiment, the buffer roller 8 is made of rubber, and the diameter of the buffer roller 8 is greater than the opening width of the primary buffer seat 7. The buffer plate 9 adopts an arc-shaped structure that protrudes to one side of the moving plate 4, and the length of the buffer plate 9 is greater than half the length of the moving plate 4. The buffer plate 9 is made of shape memory metal to buffer the force, and after deformation, it can return to its original shape, making it more durable.

[0023] The steps for performing the work are as follows:

[0024] The base 1 is installed around the material handling machine. The contact switch 10 is connected to the controller of the material handling machine and is used to control the emergency stop of the material handling machine. When it is hit by a collision, the buffer roller 8 in the first-level buffer seat 7 performs first-level buffering. If the force is large, after being buffered by the buffer roller 8, part of the force is transmitted to the spring damping shock absorber 5 between the mounting seat 6 and another mounting seat 6 for second-level buffering. Then the spring damping shock absorber 5 pushes the moving plate 4 to move to the left. The second magnet 32 ​​moves to the left along the direction of the guide column 33. The damping spring 34 is compressed. At the same time, due to the attraction of the first magnet 31 and the second magnet 32, it is more difficult for the second magnet 32 ​​to move, thus performing third-level buffering. Finally, the moving plate 4 hits the buffer plate 9, and the buffer plate 9 performs fourth-level buffering. If it still cannot eliminate all the force, the moving plate 4 continues to move. The protrusion 11 squeezes the contact switch 10, and the emergency stop operation of the material handling machine is realized through the contact switch 10, thereby protecting the material handling machine.

[0025] Through the above steps, a multi-stage buffer mechanism is set up. By absorbing the force of impact in multiple stages, the material handling machine is not subjected to a large impact force, thus playing a good anti-collision protection role. This is crucial for extending the service life of the material handling machine and ensuring its integrity and safety. The multi-stage shock absorption structure can absorb impact energy in segments, allowing the impact force to be dispersed and released over a longer period of time, effectively reducing the impact intensity on the material handling machine. Moreover, the overall size is small, and it can be installed around the material handling machine without affecting the loading and unloading of materials. It is convenient to use and solves the technical problems of inconvenient material loading and unloading and insufficient buffering effect.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
