Description

Technical Field

[0001] This utility model relates to the field of transportation device technology, and in particular to an auxiliary device for transporting metal materials. Background Technology

[0002] In fields such as industrial production, construction, and machinery manufacturing, the transportation of metal materials such as steel pipes, steel plates, and structural steel is a key link connecting production and application. The safety and efficiency of the transportation process directly affect the overall work progress and cost control.

[0003] Current methods for transporting metal materials mostly rely on simple clamping, such as rope binding. Metal materials are tied to transport frames or lifting equipment using steel wire ropes, nylon ropes, etc. This method requires manual and repeated adjustment of rope tension, which is not only cumbersome, but also prone to slippage due to the smooth surface of the material and bumpy transport, causing the material to shift or even fall. Especially in high-altitude lifting scenarios, if the rope breaks or loosens, it can easily lead to safety accidents such as equipment damage and personal injury. Utility Model Content

[0004] The purpose of this invention is to solve the problems of cumbersome operation and poor safety of clamping methods in the existing technology for transporting metal materials, and to provide an auxiliary device for transporting metal materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a metal material transportation auxiliary device, comprising a metal material body, a hook mechanism engaged with the outer surface of the metal material body, the hook mechanism including a lifting hook, the inner wall of the lifting hook having a rounded corner, the outer surface of the lifting hook having a bevel, a clamping mechanism fixedly connected to the outer surface of the lifting hook, the clamping mechanism including a slider, the outer surface of the slider being slidably connected to a housing, the inner wall of the housing having a first sliding groove, the inner wall of the slider having a second sliding groove, the inner wall of the second sliding groove being slidably connected to a limit block, the outer surface of the limit block being fixedly connected to a connector, the outer surface of the slider having a bevel, and the outer surface of the connector being fixedly connected to two fixing members.

[0006] In a preferred embodiment, the inner walls of the two fixing members are rotatably connected to a transmission mechanism, the transmission mechanism including a connecting block, a connecting rod fixedly connected to the outer surface of the connecting block, a spring slidably sleeved on the outer surface of the connecting rod, and a pull ring fixedly connected to the outer surface of the connecting rod.

[0007] In a preferred embodiment, the inner wall of the housing has a through hole, and the outer surface of the connecting rod is slidably connected to the inner wall of the housing.

[0008] In a preferred embodiment, the inner wall of the lifting hook is engaged with the outer surface of the metal material body.

[0009] In a preferred embodiment, the outer surface of the connecting block is rotatably connected to the inner wall of the fixing member.

[0010] In a preferred embodiment, the outer surface of the slider is slidably connected to the outer surface of the connector.

[0011] In a preferred embodiment, a slider is fixedly connected to the outer surface of the lifting hook.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention utilizes a spring-driven transmission mechanism to provide elastic preload. During clamping, the spring force pushes the connecting rod, causing the lifting hook to quickly engage and maintain a stable clamping state. Even with slight bumps during transport, the spring's cushioning effect prevents a sudden decrease in clamping force, effectively preventing material from falling off. Furthermore, the weight of the metal material is transferred to the connecting rod via the lifting hook, and the resulting tension further maintains the hook's clamping position, preventing material from slipping off. The clamping process eliminates the need for manual judgment of tightness; the device automatically clamps upon reaching the desired position using a mechanical structure, avoiding inconsistent clamping results due to operational differences and significantly improving work efficiency.

[0024] 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.

[0025] Example 1

[0026] like Figures 1-5 As shown, this utility model provides a technical solution: a metal material transportation auxiliary device, including a metal material body 1, a hook mechanism 2 engaged with the outer surface of the metal material body 1, the hook mechanism 2 including a lifting hook 21, the inner wall of the lifting hook 21 engaged with the outer surface of the metal material body 1, the inner wall of the lifting hook 21 having a rounded corner 22, the outer surface of the lifting hook 21 having a bevel 23, and a clamping mechanism 3 fixedly connected to the outer surface of the lifting hook 21, the clamping mechanism 3 including a slider 31, and the lifting hook 21 The outer surface of the slider 31 is fixedly connected to the outer surface of the slider 31. The outer surface of the slider 31 is slidably connected to the outer surface of the housing 32. The inner wall of the housing 32 is provided with a first groove 34. The inner wall of the slider 31 is provided with a second groove 35. The inner wall of the second groove 35 is slidably connected to a limit block 36. The outer surface of the limit block 36 is fixedly connected to a connector 33. The outer surface of the slider 31 is slidably connected to the outer surface of the connector 33. The outer surface of the slider 31 is provided with an angle 37. The outer surface of the connector 33 is fixedly connected to two fasteners 38.

[0027] In this embodiment, the lifting hooks 21 are designed such that their hook openings match the cross-sectional shape of the metal material body 1, facilitating the engagement and connection of the two lifting hooks 21 with the two sides of the metal material body 1. The beveled openings 23 on the outer surface of the lifting hooks 21 allow the metal material body 1 to slide into the inner walls of the two lifting hooks 21. The rounded corners 22 make the connection smoother. The two lifting hooks 21 are fixed to two sliders 31, and the sliders 31 have lugs on both sides. The cross-section of the sliders 31 matches the shape of the first groove 34 on the inner wall of the outer shell 32. The slider 31 is slidably connected to the inner wall of the outer shell 32. The second groove 35 opened on the inner wall of the two sliders 31 facilitates the sliding of the limiting block 36 inside the slider 31. The limiting block 36 is fixed on both sides of the connector 33. The two sides of the connector 33 have an inclined angle, which is consistent with the inclined angle of one side of the slider 31. This facilitates the two sliders 31 to be slidably connected to both sides of the connector 33. The longitudinal movement of the connector 33 is converted into the lateral sliding of the two sliders 31, thereby causing the lifting hook 21 fixed on the slider 31 to retract towards the middle and clamp the metal material body 1.

[0028] Example 2

[0029] like Figures 1-5 As shown, the inner walls of the two fixing members 38 are rotatably connected to a transmission mechanism 4. The transmission mechanism 4 includes a connecting block 41. The outer surface of the connecting block 41 is rotatably connected to the inner wall of the fixing member 38. A connecting rod 42 is fixedly connected to the outer surface of the connecting block 41. A spring 43 is slidably sleeved on the outer surface of the connecting rod 42. A pull ring 44 is fixedly connected to the outer surface of the connecting rod 42. A through hole is opened in the inner wall of the outer shell 32. The outer surface of the connecting rod 42 is slidably connected to the inner wall of the outer shell 32.

[0030] In this embodiment, by designing a connecting block 41, in conjunction with a fixing member 38, radial power is transmitted to the connecting member 33. The connecting block 41 is fixed on the connecting rod 42, and the connecting rod 42 slides on the inner wall of the outer shell 32. A pull ring 44 is fixedly connected to the other end of the connecting rod 42. The pull ring 44 is matched with the existing lifting chain. Pulling the pull ring 44 drives the connecting rod 42 to pull the connecting member 33, causing the two sliders 31 to move closer to the middle. The spring 43, which is slidably sleeved on the outer surface of the connecting rod 42, pushes the connecting rod 42 by the elastic force of the spring 43, causing the two lifting hooks 21 to quickly engage and clamp the two sides of the metal material body 1.

[0031] Working principle:

[0032] like Figures 1-5As shown, when workers need to transport the metal material body 1, it is necessary to lift and transfer the metal material body 1. Then, the device needs to be installed on the chain of the existing lifting equipment. Then, the bevel 23 on the outer surface of the lifting hook 21 plays a guiding role. The outer surface of the metal material body 1 first contacts the bevel 23. The angle of inclination of the bevel 23 guides the material to slide along the bevel into the inner wall of the lifting hook 21. The rounded corner 22 of the inner wall of the lifting hook 21 reduces frictional resistance and avoids jamming due to sharp corners when the material slides in, ensuring that the material slides in smoothly. When the lifting hook 21 is engaged, the spring force of the spring 43 pushes the connecting rod 42 in the opposite direction. The reset of the connecting piece 33 pushes the slider 31 laterally closer through the oblique angle 37, so that the lifting hook 21 is quickly tightened and finally firmly engaged on the outer surface of the metal material body 1, completing the clamping action. The external lifting equipment lifts the entire device through the pull ring 44. At this time, the weight of the metal material body 1 is transmitted to the connecting rod 42 through the lifting hook 21. The tension generated by the weight further keeps the lifting hook 21 in a clamped state, preventing the material from falling off.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
