Technical Field

[0001] This utility model relates to the field of steel component construction equipment, specifically to a steel component lifting device for steel structure construction. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. Due to their light weight and simple construction, they are widely used in large factories, stadiums, high-rise buildings, bridges, and other fields. During construction, steel components need to be transported to higher locations using lifting platforms.

[0003] During the lifting of steel components, the components need to be loaded onto a lifting platform first. However, existing loading platforms cannot lower their side panels, making loading inconvenient. After loading, the steel components also need to be manually secured to the platform to prevent them from falling off during lifting and causing accidents. Therefore, those skilled in the art have provided a steel component lifting device for steel structure construction to solve the problems mentioned in the background art. Utility Model Content

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figures 1-4 In this embodiment, a steel component lifting device for steel structure construction is provided, including a base plate 1, side plate structures 2 rotatably connected to both sides of the base plate 1, and a steel component body 3 placed above the base plate 1 between the side plate structures 2.

[0028] The side plate structure 2 includes a plate body 21. Rotating grooves 22 are provided on both sides of the plate body 21. A clamping roller 23 is rotatably connected inside the rotating grooves 22. A slot 24 is provided inside the plate body 21 above the rotating grooves 22. A gear 25 is fixedly connected to one side of the clamping roller 23 through the slot 24. A fixing block 26 is fixedly connected to the inside of the plate body 21. The fixing block 26 is located on one side of the slot 24. A rack 27 is slidably connected inside the fixing block 26. One end of the rack 27 is located on one side of the gear 25 and meshes with the gear 25. A lifting ring 28 is fixedly connected to the other end of the rack 27. A fixed pulley 29 is rotatably connected to one end of the rack 27 inside the plate body 21.

[0029] In use, the base plate 1 is placed on the ground, and the plate body 21 is flattened on both sides of the base plate 1 under the action of gravity. The steel component body 3 is placed on the base plate 1 by the equipment. The hook of the lifting equipment is hooked on the lifting ring 28 by passing around the fixed pulley 29. The lifting device pulls the plate body 21 to rotate and lift it up. When the lifting ring 28 is pulled, it also drives the rack 27 to move. The movement of the rack 27 drives the gear 25 to rotate. The gear 25 drives the clamping roller 23 to rotate. One end of the clamping roller 23 rotates to the top of the base plate 1 to clamp the steel component body 3 placed on the base plate 1 and prevent it from moving during the lifting process.

[0030] In this embodiment, specifically, a connecting sleeve 211 is fixedly connected to the lower part of the plate 21, and openings matching the connecting sleeve 211 are provided on both sides of the base plate 1. The connecting sleeve 211 is located inside the openings, and rotating shafts are rotatably connected to both sides of the base plate 1, with the rotating shafts passing through the connecting sleeve 211. The plate 21 is rotatably connected to the base plate 1 through the connecting sleeve 211.

[0031] In this embodiment, specifically, an anti-detachment baffle is provided on the outer side of the fixed pulley 29. Through the anti-detachment baffle, the hook cable of the lifting device passes around the fixed pulley 29. When the hook cable pulls up the plate 21, the hook cable is less likely to separate from the fixed pulley 29, thus stably lifting the plate 21. Alternatively, using a deeper fixed pulley 29 can also prevent the hook cable from detaching from the fixed pulley 29.

[0032] In this embodiment, specifically, a gap is provided between the lifting ring 28 and the plate 21. This gap, allowing for the insertion of a hook, facilitates the connection between the hook and the lifting ring 28.

[0033] In this embodiment, specifically, the clamping roller 23 is made of an elastic material. By using an elastic material, the length of the clamping roller 23 extending into the upper part of the base plate 1 is extended as much as possible, so that when a small amount of steel structure is loaded on the base plate 1, it can be clamped by the clamping roller 23. At the same time, when a large number of steel components are loaded, the clamping roller 23 can also deform to clamp them.

[0034] In this embodiment, specifically, the clamping roller 23 includes a rotating part and a disassembly part. The disassembly part is located on the side away from the rotation center of the clamping roller 23, and is installed on the rotating part by fasteners. By designing the clamping roller 23 as a split structure, the side in contact with the steel structure can be replaced, avoiding wear after repeated clamping contacts that would prevent it from clamping the steel component, thus extending the service life of the device.

[0035] In this embodiment, specifically, a hole 210 is formed inside the plate 21, and the hole 210 is located between the rotating grooves 22. By making the hole 210, the weight of the plate 21 is reduced, the load on the lifting device is reduced, and the service life of the lifting device is effectively extended.

[0036] In this embodiment, specifically, the upper surface of the base plate 1 is provided with anti-slip texture. The anti-slip texture increases the friction between the steel component and the base plate 1, making it less likely for the steel component to slide on the base plate 1.

[0037] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
