[0002] Precast concrete components refer to concrete building components that are pre-cast in a factory or prefabrication yard, cured, and then transported to the construction site for assembly. They are widely used in prefabricated buildings, improving construction efficiency, reducing on-site pollution, and enhancing project quality. During transportation, fixed supports are required.

[0003] Currently, the most common method for securing precast concrete components is to use traditional steel wire ropes and chains for binding, with the steel wire ropes secured by a rope tensioner. While this traditional method is low-cost and adaptable, it relies on worker experience, has uneven tightening force, and is prone to loosening during transport, requiring mid-journey checks and tightening, thus affecting transport efficiency. Furthermore, manual operation is inefficient and cannot meet the needs of large-scale transport. Utility Model Content

[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] Please see Figures 1-5 As shown, a loading and fixing bracket for precast concrete components includes a mounting plate 1, and further includes:

[0023] A mounting frame 2 is fixed to the bottom of mounting plate 1, which serves as the mounting base for the entire bracket. A motor 3 is mounted at the front end of mounting frame 2. A bidirectional threaded rod 4 is fixedly connected to the drive end of motor 3. The bidirectional threaded rod 4 uses a specially designed left-right double-threaded design, converting the rotational motion of motor 3 into linear motion. Mounting frame 2 serves as the mounting base for motor 3 and bidirectional threaded rod 4. A rotating column 5 is rotatably connected to the other end of bidirectional threaded rod 4. One side of the inner wall of mounting frame 2 is fixedly connected to the outer wall of rotating column 5, which serves as the terminal support point for bidirectional threaded rod 4. Mounting blocks 6 are threadedly connected to both sides of the outer wall of bidirectional threaded rod 4. Connecting columns 7 are fixedly connected to the top of each mounting block 6, and connecting brackets 8 are fixedly connected to the top of each connecting column 7. Connecting brackets 8 convert the linear motion of bidirectional threaded rod 4 into clamping force. Motor 3 is started by a control switch, causing motor 3 to drive bidirectional threaded rod 4 to rotate, thus... The mounting block 6 moves linearly, thereby pushing the fixing plate 14 to quickly and adaptively clamp precast components of different sizes, greatly improving the transportation efficiency. The top of the mounting plate 1 is set at the bottom of the two connecting frames 8. The inner walls of the two connecting frames 8 are provided with mounting parts 9. The interior of the two mounting parts 9 is provided with spring grooves 10. The spring grooves 10 can provide movement space for the buffer mechanism. The inner walls of the two spring grooves 10 are slidably connected with sliders 11. One end of the two sliders 11 is provided with a spring 12. The two springs 12 are both located inside the spring grooves 10. The other end of the two sliders 11 is fixedly connected with a piston rod 13. The opposite sides of the two piston rods 13 are fixedly connected with a fixing plate 14. When the pressure applied by the concrete component to the fixing plate 14 is transmitted to the slider 11 through the piston rod 13, the spring 12 in the spring groove 10 is compressed to form an elastic buffer, which effectively absorbs the vibration and impact during transportation and improves transportation safety.

[0024] Mounting posts 15 are fixedly connected to opposite sides of the two connecting frames 8. Connecting rods 16 are fixedly connected to one end of each of the two mounting posts 15. Mounting heads 17 are fixedly connected to one end of each of the two connecting rods 16. Sliding blocks 18 are slidably connected to the outer walls of the two connecting rods 16, thus forming a quick-installation mechanism. Mounting grooves 19 are provided on the inner walls of the two mounting parts 9 near the connecting frame 8, providing installation space for the quick-installation mechanism. Two spring grooves 10 are located on opposite sides of the mounting grooves 19 near the connecting frame 8. Sliding grooves 20 are provided on both sides of the inner walls of the mounting grooves 19, providing movement space for the locking mechanism. The outer walls of the two mounting heads 17 are located on the inner walls of the mounting grooves 19. Fixing blocks 21 are fixedly connected to the inner walls of the two sliding grooves 20, and the inner walls of the two fixing blocks 21 are slidably connected to the inner walls of the two fixing blocks 21. The device is connected to two sliding rods 22, each with a spring 23 on its outer wall. One end of each sliding rod 22 is fixedly connected to a locking block 24, which engages with one side of the mounting head 17. The other end of each sliding rod 22 is fixedly connected to an anti-detachment block 25, thus forming a locking mechanism. When the mounting head 17 enters the mounting groove 19, the inclined surface of the locking block 24 slides across the outer wall of the mounting head 17, causing the sliding rod 22 to move into the sliding groove 20 and press against the spring 23. When the locking block 24 passes the mounting head 17, the spring 23 causes the sliding rod 22 to reset, so that the locking block 24 rests against the bottom of the mounting head 17, thus completing the quick installation. Through the quick-install locking mechanism, a one-click quick installation and disassembly function is realized, and the adapter can be quickly replaced according to different component sizes.

[0025] Wheel base plates 26 are fixedly connected to the bottom left and right sides of the mounting plate 1. Universal wheels 27 are installed on the bottom front and rear sides of the two wheel base plates 26. The wheel base plates 26 provide installation space for the universal wheels 27. A load-bearing plate 28 is fixedly connected to the top of the mounting plate 1. The load-bearing plate 28 is set on the front and rear sides of the connecting frame 8. The load-bearing plate 28 can bear the components and play a role in stable support.

[0026] Working principle: The entire system uses mounting plate 1 as the load-bearing foundation. When it is necessary to fix prefabricated components, the components are mounted on the upper end of the load-bearing plate 28. The motor 3 is started to drive the bidirectional threaded rod 4 to rotate, which drives the mounting blocks 6 on both sides to move synchronously in opposite directions along the bidirectional threaded rod 4. This, in turn, drives the connecting column 7 to push the connecting frame 8 to adjust the distance between the two fixing plates 14, realizing adaptive clamping of components of different sizes, thereby improving the loading efficiency. During the clamping process, the pressure exerted by the components on the fixing plate 14 is transmitted to the slider 11 through the piston rod 13, compressing the spring 12 in the spring groove 10 to form an elastic buffer, effectively absorbing the pressure during transportation. During the process, the vibration and impact are mitigated. Simultaneously, when the mounting head 17 enters the mounting groove 19, it slides across the inclined surface of the locking block 24. When the locking block 24 reaches the bottom of the mounting head 17, the spring 23, due to its reaction force, drives the sliding rod 22, causing the locking block 24 to return to its original position and press against the bottom of the mounting head 17 to achieve automatic locking, enabling quick installation and ensuring stable clamping. When it is necessary to change the clamp, simply push the mounting part 9 inward, causing the locking block 24 to drive the sliding block 18 to press against the bottom of the mounting head 17. The inclined surface of the locking block 24 passes through the inclined surface of the sliding block 18, causing the quick-installation mechanism to disengage from the mounting groove 19 for clamp replacement. This achieves multi-component adaptation, thereby improving work efficiency.
