Description

Technical Field

[0001] The present invention relates to the technical field of hoisting prefabricated building components, and more particularly to a hoisting device for assembled prefabricated building components. Background Art

[0002] Prefabricated components for construction sites are building components pre-produced in factories or prefabrication yards and transported to the construction site for direct assembly or installation, replacing traditional on-site casting or masonry construction methods. Through standardized design and industrialized production, these components significantly improve construction efficiency, reduce costs, and minimize environmental pollution. Because these prefabricated components can be cast or masoned into a variety of shapes, such as beams, columns, floor slabs, and wall panels, tailored to building requirements—beams include T-shaped, I-shaped, and box-shaped—prefabricated components are widely used in the construction industry.

[0003] Because T-beams are often used to span large spans (such as bridges, factories, and parking lots), they are often installed high above the ground (for example, at the top of bridge piers or between building floors). Furthermore, T-beams are heavy (possibly weighing several to tens of tons) and are installed several or even dozens of meters above the ground. Therefore, their installation requires a hoisting device. In the prior art, the hoisting process for T-beams typically involves tying a rope around the T-beam, hooking the rope onto a hook on the hoisting device, and then tying a knot on the hook to secure the rope to the hook. This prevents the T-beam from swaying excessively during the hoisting process.

[0004] At present, the hoisting devices in the prior art have the following drawbacks during the actual hoisting process: Since the T-beam itself is very heavy, if the T-beam is hoisted on the lifting device with only one or two ropes, the ropes will not be able to control the direction of the T-beam, causing the T-beam to swing or rotate irregularly when being hoisted. Furthermore, the T-beam may collide with other objects or buildings during the swinging or shaking process, thereby causing personnel safety problems and material loss problems. Summary of the Invention

[0027] The present invention also discloses a method for hoisting a hoisting device for prefabricated components of an assembled building, the method comprising the following steps: Preparation and installation before lifting S1: First, check the lifting device to ensure that all parts are in normal use; S11: Place the end of the sling rope 231 between the four clamping pieces 227, and then press the clamping sleeve 230 downward until the clamping sleeve 230 contacts the limiting rod 229, so that the end of the sling rope 231 is fixed to the positioning rod 226 through the clamping pieces 227; S12: Fix the positioning rod 226 to the connecting plate 245; S13: Fix the split clamp 214 to the hook 1 with a nut, then hang the two balancing ropes 212 on the two support columns 211 respectively. Finally, fix the T-beam 3 to the suspension rope 231 and the two balancing ropes 212 in sequence, and check the connection ends of the suspension rope 231 and the balancing rope 212. Adjustment and fixation S2: Turn the hand wheel 243 counterclockwise, the threaded shaft 242 rotates, and the threaded ring 244 drives the positioning rod 226 on the connecting plate 245 to move upward, so that the suspension rope 231 drives the T beam 3 to gradually move upward until the tapered member 224 is also fully extended into the tapered groove 223; S21: The conical member 224 pushes the guide cover 222 upwards, and the scale is observed to move the guide cover 222 to the target position, then the hand wheel 243 is stopped, and the T beam 3 is fixed. S22: During the hoisting process of the T-beam 3, the wireless tension sensor 232 can be used to alarm the terminal to display the load and shaking data in real time. If the hoisting device exceeds the limit, the hoisting will be automatically suspended and an alarm will be issued.

[0028] Disassembly and recycling S3: After the lifting is completed, dismantle the lifting device in the reverse order of steps 2 and 3; S31: Finally, check whether all parts are intact. If any parts are damaged or worn, they should be replaced in time. Arrange the disassembled parts and store them in a dry and ventilated place for next use.

[0029] Working principle: Step 1: Preparation and installation before lifting First, check the lifting device to ensure that all parts are functioning properly. After confirming that everything is functioning properly, place the end of the lifting rope 231 between the four clamping pieces 227. Then, squeeze the clamping sleeve 230 downward until the clamping sleeve 230 contacts the limiting rod 229. At this time, the four clamping pieces 227 squeezed by the clamping sleeve 230 also move closer to the lifting rope 231, and the clamping cone 228 is also inserted into the interior of the lifting rope 231. At this time, the end of the lifting rope 231 is fixed to the positioning rod 226 through the clamping pieces 227. The operator then extends the positioning rod 226 from the tapered groove 223 into the guide cover 222. When the top of the positioning rod 226 contacts the connecting plate 245, the operator twists the positioning rod 226 clockwise until it stops, thereby fixing the positioning rod 226 on the connecting plate 245. Finally, the operator fixes the split clamp 214 to the hook 1 with a nut, and hangs the two balancing ropes 212 on the two support columns 211 respectively. Then, the T-beam 3 is fixed to the suspension rope 231 and the two balancing ropes 212 in sequence, and the connection ends of the suspension rope 231 and the balancing rope 212 are inspected. Step 2: Adjustment and fixation After step 1 is confirmed to be correct, the operator can rotate the hand wheel 243 counterclockwise, and then the threaded shaft 242 rotates synchronously with the rotation direction of the hand wheel 243, further causing the threaded ring 244 to drive the positioning rod 226 on the connecting plate 245 to move upward, thereby driving the hanging rope to gradually move the T beam 3 upward. When the threaded ring 244 moves to the position of two-thirds of the threaded shaft 242, the tapered member 224 is also completely inserted into the tapered groove 223. At this time, it is necessary to continue to rotate the hand wheel 243 counterclockwise to drive the threaded shaft 242 to rotate continuously, so that the tapered member 224 pushes the guide cover 222 upward through the tapered groove 223, thereby gradually squeezing the elastic member 248 in the process of moving the outer sleeve 246 toward the inner sleeve 247 through the upward force of the guide groove. At the same time, observe the scale to make the guide cover 222 move to the target position, then stop rotating the hand wheel 243, and then complete the fixing of the T beam 3; During the hoisting process of the T-beam 3, the wireless tension sensor 232 provided at the bottom of the hoisting rope can be used to alarm the terminal to display the load and shaking data in real time. If the hoisting device exceeds the limit, the hoisting will be automatically suspended and an alarm will be issued. Step 3: Disassembly and recycling After the hoisting is completed, the hoisting device is disassembled in the reverse order of steps 2 and 3. When the hand wheel 243 is rotated counterclockwise, the elasticity of the elastic member 248 exerts a downward force on the guide cover 222, the connecting plate 245 and the threaded ring 244, forcing the threaded ring 244 to move downward, causing the threaded ring 244 to accelerate the rotation of the threaded shaft 242, thereby sharing the force of the operator turning the hand wheel 243. Finally, check whether all parts are intact. If any parts are damaged or worn, they should be replaced in time. Arrange the disassembled parts and store them in a dry and ventilated place for next use.

A method for hoisting a prefabricated component hoisting device for assembled buildings, applied to the prefabricated component hoisting device for assembled buildings according to claim 7, characterized in that: The hoisting method of the hoisting device for prefabricated components of assembled buildings comprises the following steps: Preparation and installation before lifting S1: First, check the lifting device to ensure that all parts are in normal use; S11: placing the end of the sling rope (231) between the four clamping pieces (227), and then squeezing the clamping sleeve (230) downward until the clamping sleeve (230) contacts the limiting rod (229), so that the end of the sling rope (231) is fixed to the positioning rod (226) through the clamping piece (227); S12: Fixing the positioning rod (226) to the connecting plate (245); S13: Fix the split clamp (214) to the hook (1) through a nut, then hang the two balancing ropes (212) on the two support columns (211) respectively, and finally fix the T beam (3) to the suspension rope (231) and the two balancing ropes (212) in sequence, and check the connection ends of the suspension rope (231) and the balancing rope (212); Adjustment and fixation S2: Turn the hand wheel (243) counterclockwise, the threaded shaft (242) rotates to cause the threaded ring (244) to drive the positioning rod (226) on the connecting plate (245) to move upward, thereby driving the suspension rope (231) to gradually move the T beam (3) upward until the tapered member (224) is also completely inserted into the tapered groove (223); S21: The conical member (224) pushes the guide cover (222) upwards, and when the guide cover (222) moves to the target position by observing the scale, the hand wheel (243) is stopped, and the fixing of the T beam (3) is completed. S22: During the hoisting process of the T-beam (3), the alarm terminal can display the load and shaking data in real time through the wireless tension sensor (232). If the hoisting device exceeds the limit, the hoisting will be automatically suspended and an alarm will be issued; Disassembly and recycling S3: After the lifting is completed, dismantle the lifting device in the reverse order of steps 2 and 3; S31: Finally, check whether all parts are intact. If any parts are damaged or worn, they should be replaced in time. Arrange the disassembled parts and store them in a dry and ventilated place for next use.
