[0002] As a vertical transportation equipment, elevators are widely used in industrial production, especially in mining, metallurgy, construction, warehousing and other fields. Elevators are one of the main equipment for material handling. Its superior vertical transportation capacity makes it indispensable in scenarios where large amounts of materials need to be transported efficiently. The safety of elevators is crucial to ensure the smooth progress of production operations, especially measures to prevent materials from accidentally slipping during transportation.

[0003] In actual application, elevators are usually used to transport materials in various forms, including particles, powders, blocks, etc. However, when handling lightweight and smooth materials such as thin plates and plates, due to the characteristics of these materials, traditional methods of handling such as clamping and bundling can easily cause deformation of the material surface, thus affecting the appearance quality and performance of the product. Therefore, for such materials, lifting methods such as chains and gear conveyors that do not apply additional pressure are often used. However, there is a significant problem in the application of these lifting methods, that is, the materials are prone to slip due to factors such as gravity or equipment vibration. Especially when handling thin plate materials with smooth surfaces, the risk of slipping is more prominent. This not only poses a potential threat to the operators below, but may also damage the equipment or cause production interruptions, thereby affecting production efficiency.

[0004] Therefore, it is particularly important to design an anti-fall structure for a hoist. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-drop structure for a hoist, which can effectively prevent lightweight and smooth-surfaced materials such as thin plates and plates from slipping due to gravity or equipment vibration during the lifting process, thereby improving the safety of the lifting operation.

[0007] Preferably, the lifting component adopts a linear module, which includes a screw rod vertically connected to the frame and a driving motor driving the screw rod to rotate.

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] Example: See Figure 1 - Figure 4 In the present embodiment, an anti-fall structure for an elevator is provided, which is specifically used to solve the problem that the elevator is prone to slipping when transporting light and smooth materials such as thin plates and plates, and the safety of the lifting operation is significantly improved. The structure specifically includes a frame 11, and the frame 11 is symmetrically provided with two groups of lifting units 12. The lifting unit 12 is provided with a support portion 13 for carrying and lifting objects. The rear side of the frame 11 is slidably connected with an anti-fall component 14 along its vertical direction. The anti-fall component 14 is provided with a protective wing plate 15 that can be deployed and retracted. The anti-fall component 14 is also adapted to be equipped with a lifting component 16 for driving it to move up and down. The lifting component 16 drives the anti-fall component 14 so that the protective wing plate 15 is always located below the object when the object is lifted by the support portion 13.

[0023] Specifically, in the present embodiment, the lifting unit 12 adopts a synchronous belt transmission mechanism, which includes two sets of synchronous belts, the support part 13 is fixed between the two sets of synchronous belts, and the two sets of lifting units 12 share a motor. The two ends of the object are respectively placed on the support part 13 of a set of lifting units 12. The lifting unit 12 is driven by a synchronous belt transmission mechanism to ensure the stability and synchronization of the object during the lifting process. Through the coordinated work of the two sets of lifting units 12, the support part 13 can lift the object vertically. In this process, the anti-falling component 14 is moved up and down through the lifting component 16 to cooperate with the lifting operation of the object.

[0024] In actual application, when the support part 13 is in a low position, the protective wing plate 15 in the anti-falling component 14 is retracted to avoid interfering with the placement of the object and the initial lifting operation. When the support part 13 is lifted to a certain height, higher than the anti-falling component 14, the protective wing plate 15 is unfolded so that it is located below the object and lifted together with it to provide protection. This design ensures that when the object is lifted to a high position, no matter what reason it slides or falls, it can be caught by the protective wing plate 15 to prevent it from falling directly to the ground or hitting the subsequent lifted object. In particular, when the frame 11 of the hoist vibrates or other external forces act, which may cause the object to slide, the protective wing plate 15 can effectively play a protective role, firmly support the object in place or buffer the impact of its fall, and avoid equipment damage or personal injury caused by the falling of the object. The design of the anti-falling structure has high safety and reliability, especially when handling materials that are easy to slide, such as thin plates and smooth plates, it provides additional protection and reduces the risk of accidents.

[0025] In this embodiment, the lifting component 16 adopts a linear module, which includes a screw rod 21 connected to the frame 11 in a vertical rotation and a drive motor 22 driving the screw rod 21 to rotate. The anti-falling component 14 is sleeved on the screw rod 21 and threadedly matched with it. The rotation of the screw rod 21 drives the anti-falling component 14 to move along its axial direction, so as to achieve the up and down adjustment of the protective wing plate 15 to meet the protection requirements of objects at different heights. Specifically, the speed or direction of the drive motor 22 is adjusted so that the anti-falling component 14 can be accurately positioned according to the lifting height of the object. When the support part 13 brings the object up, the drive motor 22 drives the screw rod 21 to rotate, and the anti-falling component 14 rises accordingly, ensuring that the protective wing plate 15 is always under the object to provide real-time protection. On the contrary, when the support part 13 descends, the screw rod 21 rotates in the opposite direction, the anti-falling component 14 descends accordingly, and the protective wing plate 15 is retracted to a safe position to avoid interfering with the placement and transportation operation of the object.

[0026] In this embodiment, the anti-fall component 14 includes a slide 31 that is sleeved with the screw 21, and guide blocks 32 are provided on both sides of the slide 31, and guide holes 33 are provided on the guide blocks 32. Two groups of guide posts 34 are vertically provided on the frame 11, and the guide posts 34 are slidably connected and adapted to the guide blocks 32 through the guide holes 33, so as to ensure that the anti-fall component 14 can move smoothly in the vertical direction under the drive of the screw 21. Specifically, the sliding fit design between the guide posts 34 and the guide blocks 32 provides a dual guiding function of the anti-fall component 14, increases the stability and accuracy of the movement of the anti-fall component 14, and can effectively prevent the anti-fall component 14 from deviating from the predetermined track due to the vibration of the frame 11 or the influence of external forces, especially during the operation of the hoist.

[0027] In this embodiment, two groups of protection units 41 are arranged on both sides of the slide 31, and the protection units 41 include protection flaps 15 hinged on the slide 31, and the protection flaps 15 are adapted to be driven by a driving component 42 for driving them to swing around the hinge. Specifically, the driving component 42 adopts a double-shaft motor, and the motor shafts at both ends of the motor are threadedly sleeved with sliders 43. A guide shaft 45 is arranged on the slider 43 (the slider 43 is provided with a side rod 44, and the guide shaft 45 is arranged at the end of the side rod 44), and the guide shaft 45 is slidably connected and adapted to the protection flap 15 through a guide groove 46 on the protection flap 15. When the protection flap 15 needs to be unfolded, the driving component 42 drives the slider 43 to move, so that the protection flap 15 swings around the hinge and unfolds, and is located below the object; when protection is not needed, the driving component 42 retracts the protection flap 15 to both sides of the slide 31 through reverse operation, which does not affect the normal lifting and transportation of the object.

[0028] The guide block 32 is provided with a slide groove 47 that is slidably matched with the slider 43. Specifically, the slide groove 47 is provided on the guide block 32 and can be slidably connected with the slider 43. When the driving component 42 (such as a dual-axis motor) drives the slider 43 to move, the slider 43 slides along a specific track in the slide groove 47, ensuring that the protective wing 15 has precise control during the swinging process at the hinge. This sliding fit design allows the protective wing 15 to be more stable when deployed and retracted, and will not be offset or stuck due to external force or equipment vibration.

[0029] The upper surface of the protective wing plate 15 is provided with a flexible pad 48. Specifically, the flexible pad 48 is made of a soft and elastic material, which can effectively reduce the impact force when the object contacts the protective wing plate 15, and prevent the surface of the object from being scratched or damaged due to direct contact with the hard protective wing plate 15. In addition, the flexible pad 48 also has a certain anti-slip effect, which can increase the friction between the object and the protective wing plate 15, and prevent the object from sliding or moving again during the sliding process. The flexible pad 48 in this embodiment can be made of materials such as silicone and rubber to meet the protection requirements.

[0030] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
