Description

Technical Field

[0001] This utility model relates to the technical field of steel structure transportation devices, specifically a hoisting device for transporting steel structures. Background Technology

[0002] Steel structures are a type of building material made of steel, commonly used in large-scale engineering structures. They are lighter than concrete, reducing building weight and making construction more economical and efficient; they are easy to transport and install, allowing for rapid on-site assembly; and they possess excellent durability and can withstand long-term use. Steel structures come in various types, including steel frames and steel plates. During transportation, they require hoisting equipment to suspend and move them onto transport vehicles.

[0003] Existing steel plate hoisting equipment clamps and suspends the plate from both sides. During the suspension process, the steel plate bends towards the center due to gravity. At this time, the two ends of the steel plate are easy to detach from the clamps. In addition, the deformation caused by the long-term suspension of the steel plate is not easy to recover.

[0004] To address this issue, the present invention provides a hoisting device for transporting steel structures, which uses a bottom clamping plate and a top clamping plate to clamp the steel plate again from both sides of the center position, thereby solving the above-mentioned problems.

[0012] Beneficial effects

[0013] This utility model provides a hoisting device for transporting steel structures. Compared with the prior art, it has the following advantages:

[0021] 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.

[0022] Example 1:

[0023] Please see Figure 1-3 A hoisting device for transporting steel structures includes a lifting beam 1. Lifting assemblies 2 are symmetrically arranged at both ends of the lifting beam 1. Clamping assemblies 3 are symmetrically arranged at the center of the bottom of the lifting beam 1. Each clamping assembly 3 includes a central plate 301 fixedly connected to the bottom end of the lifting beam 1. A central lifting ring 302 is sleeved inside the central plate 301. A central lifting cable 303 is sleeved inside the central lifting ring 302. A central clamping plate 304 is symmetrically sleeved at the outer end of the central lifting cable 303. A clamping plate 305 is rotatably connected to the outer end of the central clamping plate 304. A bottom clamping plate 306 is fixedly connected to one bottom side of the clamping plate 305. A connecting groove 307 is symmetrically opened at the top of the clamping plate 305. A top clamping plate 308 is rotatably connected inside the connecting groove 307. The purpose of this setup is to first use the clamp 205 to hold the steel plate from its four corners when transporting it, then use the bottom clamp 306 at the outer end of the clamping plate 305 to support the bottom of the steel plate, and then rotate the top clamp 308 inside the clamping plate 305 to press it down from the top of the steel plate. This prevents the steel plate from becoming unstable and falling off during suspension, while also preventing the steel plate from bending towards the center line due to gravity, which would cause the steel plate to deform.

[0024] Preferably, the clamping assembly 3 further includes a connecting shaft 309 fixedly connected to one end of the top clamping plate 308. The connecting shaft 309 is rotatably connected to the clamping plate 305. A cavity is provided at the center of the interior of the clamping plate 305. A gear 3010 is fixedly connected to the outer end of the connecting shaft 309. The gear 3010 is located inside the cavity. The clamping assembly 3 also includes a cylinder 3011 fixedly connected inside the clamping plate 305. A rack 3012 is fixedly connected to the movable end of the cylinder 3011. The rack 3012 meshes with the gear 3010 and is slidably connected inside the cavity. The purpose of this arrangement is that during the clamping process of the top clamping plate 308 and the bottom clamping plate 306 clamping the steel plate, the cylinder 3011 inside the clamping plate 305 drives the rack 3012 to slide. At this time, the rack 3012 drives the top clamping plate 308 connected to the gear 3010 to rotate.

[0025] Example 2:

[0026] Please see Figure 1-5 This embodiment provides a technical solution for a steel structure transportation hoisting equipment based on Embodiment 1: the hoisting assembly 2 includes a side plate 201 fixedly connected to the bottom end of the hoisting beam 1. A side lifting ring 202 is snapped onto the outer end of the side plate 201. A side lifting cable 203 is sleeved inside the side lifting ring 202. Side clamping plates 204 are symmetrically sleeved on the outer end of the side lifting cable 203. A clamping bracket 205 is rotatably connected inside the side clamping plate 204. The purpose of this arrangement is that when suspending the steel plate, the four clamping brackets 205 are respectively clamped at the four corners of the steel plate, and the side clamping plates 204 drive the clamping brackets 205 to slide in opposite directions, thereby clamping the steel plate.

[0027] Preferably, a suspension frame 4 is fixedly connected to the top of the lifting beam 1, and the suspension frame 4 has locking holes inside. The purpose of this arrangement is that the locking holes are used to suspend the hook. During installation, the hook is passed through the locking holes inside the suspension frame 4, thereby connecting the lifting beam 1 to the crane.

[0028] Preferably, a connecting seat 5 is fixedly connected to one side of the suspension frame 4, and a limit ring 6 is rotatably connected inside the connecting seat 5. A torsion spring 7 is fixedly connected between the limit ring 6 and the connecting seat 5. The purpose of this arrangement is that the limit ring 6 acts as a locking and limiting device for the hook, preventing the hook from detaching from the suspension frame 4 due to the swaying of the steel plate during transportation. The torsion spring 7 enhances the stability of the limit ring 6 in locking the hook.
