Abstract
Description
Technical Field
[0001] This utility model belongs to the field of component hoisting technology, specifically relating to an RFID-based prefabricated PC component hoisting device. Background Technology
[0002] The hoisting of prefabricated PC components is a crucial step in construction engineering. Traditional hoisting methods rely heavily on manual operation, which is inefficient and prone to safety hazards. With the development of Internet of Things (IoT) technology, hoisting devices based on RFID technology have gradually become a research focus. RFID technology can achieve automatic identification and real-time monitoring of prefabricated components. By embedding RFID tags on the components, hoisting equipment can accurately obtain component information, ensuring the efficiency and safety of hoisting operations. RFID technology can also achieve information sharing and data tracking, providing support for the refined management of construction projects.
[0003] Chinese patent CN216072842U discloses a prefabricated PC component hoisting system based on BIM technology, including a base, hydraulic push cylinders, and a truss. The base is arranged in two symmetrical sets, and hydraulic push cylinders are fixed to the upper surface of each base. The ends of the two sets of hydraulic push cylinders are fixed to the same truss. A clearance groove is opened in the middle of the upper surface of the truss, and a fixed platform is fixed to the lower surface of the truss. Under the action of air pressure, the patent pushes the piston B and drives the guide column B to slide outward of the side hole, thereby making the two sets of arc-shaped clamps in an opposing clamping position. The anti-slip pads and anti-slip textures installed on the surface of the arc-shaped clamps can increase the friction between the clamps and the surface of the wire rope, which can clamp the wire rope tightly and effectively prevent the operator from pulling the wire rope illegally, thus avoiding safety accidents and improving the safety of the device during use to a certain extent.
[0004] However, the current device has the following problems: the contact surface between the hook and the component is uneven, which increases the risk of the component tilting or swinging. The stability during the hoisting process is poor, which affects the hoisting accuracy and safety. Therefore, we propose an RFID-based prefabricated PC component hoisting device. Utility Model Content
[0005] The purpose of this invention is to provide an RFID-based prefabricated PC component hoisting device that can solve the problems in related technologies where the contact surface between the hook and the component is uneven, increasing the risk of component tilting or swaying, resulting in poor stability during hoisting and affecting hoisting accuracy and safety.
[0006] The specific technical solution adopted by this utility model is as follows:

[0012] A gap is left between the circumferential surface of the L-shaped fixing rod and the side surface of the threaded sleeve, and a gap is left between the circumferential surface of the L-shaped fixing rod and the side surface of the sliding sleeve.
[0013] The side of the support plate is located on the movement trajectory of the side of the protective plate, and the side of the protective plate is set as a vertical surface.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-3 As shown, an RFID-based prefabricated PC component hoisting device includes two bases 1. Hydraulic cylinders 2 are fixedly connected to the top of each base 1. The output ends of the two hydraulic cylinders 2 are fixedly connected to the same truss 3. A fixed platform 4 is fixedly connected to the side of the truss 3. A winding wheel 5 is rotatably connected to the inner wall of the fixed platform 4. A steel wire rope 6 is rotatably connected to the inner wall of the winding wheel 5. A hanging plate 7 is fixedly connected to the bottom of the steel wire rope 6. A support device 8 for supporting the workpiece is provided on the top of the hanging plate 7. The support device 8 includes a drive motor 81. The bottom of the drive motor 81 is fixedly connected to the top of the hanging plate 7. A threaded rod 82 is fixedly connected to the output shaft of the drive motor 81. A threaded sleeve 84 is threadedly connected to the threaded surface of the threaded rod 82. A support plate 88 is fixedly connected to the side of the threaded sleeve 84. The support device 8 also includes a baffle 83 fixedly connected to the bottom of the threaded rod 82. A limiting rod 85 is fixedly connected to the bottom of the hanging plate 7 to limit... A baffle 86 is fixedly connected to the bottom of the rod 85. A sliding sleeve 87 is slidably connected to the circumferential surface of the limiting rod 85. A hook 10 is fixedly connected to the bottom of the hanging plate 7. A tension sensor 11 is installed on the top of the hanging plate 7. Two guide rods 12 are fixedly connected to the top of the hanging plate 7. The circumferential surfaces of the two guide rods 12 are slidably connected to the inner wall of the truss 3. The top of the threaded rod 82 is rotatably connected to the bottom of the hanging plate 7. The side of the support plate 88 away from the threaded sleeve 84 is fixedly connected to the side of the sliding sleeve 87. The support plate 88 is located below the hook 10. The threaded sleeve 84 and the sliding sleeve 87 are located on the same horizontal plane. When lifting, the workpiece is hung by the hook 10. Then the motor works and drives the winding wheel 5 to rotate, which can rotate and wind the wire rope 6. Then the wire rope 6 pulls the hanging plate 7 to move upward as a whole, thereby lifting the workpiece. During this process, the sliding limit effect of the guide rod 12 can effectively ensure that the hanging plate 7 is more stable when lifting.
[0026] According to the above structure, when the drive motor 81 is started, the rotation of the output shaft of the drive motor 81 drives the rotation of the threaded rod 82. The rotation of the threaded rod 82 drives the movement of the threaded sleeve 84. The movement of the threaded sleeve 84 drives the movement of the support plate 88. The movement of the support plate 88 drives the sliding sleeve 87 to slide on the circumferential surface of the limiting rod 85. The limiting rod 85 restricts the rotation of the threaded sleeve 84. The first baffle 83 and the second baffle 86 restrict the movement of the threaded sleeve 84 and the sliding sleeve 87, thereby restricting the movement of the support plate 88. The support can enhance the stability of the hoisting, reduce the risk of component tilting and swaying, improve the hoisting accuracy, and evenly distribute the hoisting weight to ensure safety and reliability, and prevent damage or accidents caused by instability during the hoisting process.

The protective device 9 includes multiple L-shaped fixing rods 91, the tops of which are fixedly connected to the bottom of the hanging plate 7. A stop plate 92 is fixedly connected to the end of each L-shaped fixing rod 91 away from the hanging plate 7. Moving blocks 93 are slidably connected to the circumferential surfaces of each L-shaped fixing rod 91. A protective plate 94 is fixedly connected between two moving blocks 93. A fixing seat 95 is fixedly connected to the top of each moving block 93. A threaded sleeve 84 and... Both sides of the sliding sleeve 87 are fixedly connected to the second fixing seat 96. The inner walls of the multiple first fixing seats 95 are hinged with hinge rods 97. The ends of the multiple hinge rods 97 away from the first fixing seat 95 are hinged to the inner walls of the multiple second fixing seats 96. There is a gap between the circumferential surface of the L-shaped fixing rod 91 and the side of the threaded sleeve 84. There is a gap between the circumferential surface of the L-shaped fixing rod 91 and the side of the sliding sleeve 87. The side of the support plate 88 is located on the movement trajectory of the side of the protective plate 94. The side of the protective plate 94 is set as a vertical surface.
[0028] According to the above structure, the movement of the threaded sleeve 84 and the sliding sleeve 87 drives the movement of the fixed seat 95, the movement of the fixed seat 95 drives the movement of one end of the hinge rod 97, the movement of one end of the hinge rod 97 drives the movement of the other end of the hinge rod 97, the movement of the other end of the hinge rod 97 drives the movement of the fixed seat 96, the movement of the fixed seat 96 drives the movement of the moving block 93, and the movement of the moving block 93 drives the movement of the protective plate 94. This prevents the components from accidentally sliding or falling during the hoisting process, enhances the safety of the device, prevents damage to the surface of the components during hoisting, improves the hoisting accuracy, and ensures the safety of the working environment and the integrity of the components.
