[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0019] like Figures 1 to 4As shown, this utility model discloses a special lifting lock ring for prefabricated building PC components, comprising a traction device 1, a fixed base 2, an adjusting mechanism, and two sets of lock ring bodies 3. The traction device 1 is mounted on the top of the fixed base 2, and the bottom of the fixed block is connected to the top of the two sets of lock ring bodies 3 respectively via the adjusting mechanism. The adjusting mechanism includes a bidirectional screw 4, two sets of first sliders 5, two sets of mounting plates 6, two sets of lifting cables 7, and a buffer mechanism. A sliding groove is provided at the bottom of the fixed base 2. The left and right ends of the bidirectional screw 4 are rotatably connected to one end of the sliding groove of the fixed base 2, and the two sets of first sliders 5 are threadedly connected to the outer ends of the bidirectional screw 4, and the two sets of first sliders 5 are respectively connected to the fixed base 2. The sliding connection uses a slidable groove. The tops of the two sets of mounting plates 6 are designed with grooves. The bottoms of the two sets of first sliders 5 are respectively connected to the bottom of the grooves of a set of mounting plates. The grooves of the two sets of mounting plates 6 are slidably and tightly against one side of the fixed seat 2. The bottoms of the two sets of mounting plates 6 are respectively connected to the top of a set of lifting cables 7. The bottoms of the two sets of lifting cables 7 are respectively connected to the top of a set of locking ring bodies 3 through a buffer mechanism. By rotating the bidirectional screw, the operator moves the two sets of first sliders along the screw axis within the grooves of the fixed seat. The mounting plates move with the movement of the first sliders, thereby causing the two sets of locking ring bodies to move closer or further apart until the locking ring spacing is adjusted to a suitable level for the PC to be lifted. To determine the length of the component, two sets of locking rings are respectively placed on the lifting points of the PC component, ensuring a secure connection between the locking rings and the PC component. Then, the crane lifts the fixed base upwards using a traction device, hoisting the PC component to the designated position and slowly lowering it to complete the hoisting and placement of the PC component. According to the actual needs on site, the staff can quickly adjust the spacing between the locking rings to accommodate assembly components of different specifications and lengths, thereby improving the efficiency and effectiveness of lifting and handling building components, thus enhancing practicality.
[0020] As a preferred embodiment of the above, the buffer mechanism includes a fixed plate 8, a fixed rod 9, a sleeve 10, four sets of second sliders 11, sliding rods 12, four sets of connecting springs 13, a hinge assembly, and a limiting assembly. The bottom of the sling 7 is connected to the top of the fixed plate 8, the bottom of the fixed plate 8 is connected to the top of the fixed rod 9, the top of the sleeve 10 is provided with a groove, the outer side of the fixed rod 9 is slidably fitted into the groove of the sleeve 10 through the limiting assembly, the bottom of the sleeve 10 is rotatably connected to the top of the locking ring body 3, the bottom of the fixed plate 8 is evenly provided with four sets of sliding grooves, and each of the four sets of fixed block sliding grooves is provided with a set of sliding rods 12. The two sets of second sliders 11 are slidably connected to the sliding grooves of the fixed plate 8 through the sliding rods 12, and one end of each of the two sets of sliding rods 12 is fitted into the inner side of a set of connecting springs 13. The bottom of the four sets of second sliders 11 are respectively connected to the outer side of the sleeve 10 through the hinge assembly; when PC When the component is subjected to impact, the fixing rod slides upward in the sleeve groove, driving the second slider to slide in the fixing plate groove. The connecting spring is compressed to absorb the impact force. At the same time, the hinge assembly allows the second slider and the sleeve to rotate flexibly to adapt to forces in different directions. This can prevent damage to the PC component caused by sudden force or shaking during lifting, thus enhancing its practicality.
[0021] As a preferred embodiment of the above, the hinge assembly includes four sets of support rods 15 and multiple sets of hinge seats 14. The bottoms of the four sets of second sliders 11 are respectively hinged to one end of a set of hinge seats 14 and a support rod 15, and the outer side of the sleeve 10 is evenly hinged to the other end of the four sets of hinge seats 14 and support rods 15. During the buffering process, it can adaptively adjust according to the force conditions, ensuring the buffering effect while guaranteeing the stability of the structure, thus enhancing its practicality.
[0022] As a preferred embodiment of the above, the limiting component includes four sets of limiting blocks 16, and each of the two sets of sleeves 10 has a set of sliding grooves at its left and right ends. The four sets of limiting blocks 16 are slidably connected to the sets of sliding grooves, and the bottom ends of the two sets of fixing rods 9 are connected to the other ends of the limiting blocks 16. This limits the range of movement of the fixing rods in the sleeve grooves and prevents the buffer mechanism from failing due to excessive displacement of the fixing rods, thus enhancing practicality.
[0023] As a preferred embodiment of the above, an annular baffle 17 is also included, with the top inner side of the annular baffle 17 connected to the outer side of the fixing plate 8; this can prevent debris from entering the buffer mechanism and avoid the buffering effect being affected by debris, thus enhancing practicality.
[0024] As a preferred embodiment of the above, it also includes a rotating handle 18, with the right end of the bidirectional screw 4 passing through the right end of the groove of the fixed seat 2 and connecting to the left end of the rotating handle 18; this allows the operator to quickly rotate the bidirectional screw, thus enhancing its practicality.
[0025] As a preferred embodiment of the above embodiment, it also includes four sets of guide blocks 19. A set of sliding grooves is provided at both the front and rear ends of the fixed base 2. The four sets of guide blocks 19 are slidably connected to one end of the sliding groove of the fixed base 2. The front and rear ends of the grooves of the two sets of mounting plates 6 are respectively connected to the other end of a set of guide blocks 19. This provides precise guidance for the movement of the mounting plates, ensuring that the mounting plates move smoothly during the adjustment process and avoiding deviation, thus enhancing practicality.
[0026] This utility model discloses a special lifting lock ring for prefabricated building PC components. During operation, the operator rotates a double-ended screw by turning a handle. Two sets of first sliders move the mounting plate along the screw axis within the groove of the fixed seat. The mounting plate moves with the first sliders, causing the two sets of lock ring bodies to move closer or further apart until the lock ring spacing is adjusted to the appropriate length of the PC component to be lifted. The two sets of lock ring bodies are then placed on the lifting points of the PC component, ensuring a secure connection between the lock rings and the PC component. The crane then uses a traction device to lift the fixed seat upwards, hoisting the PC component to the designated position and slowly lowering it to complete the lifting and placement of the PC component. Before completing the above actions, the component is first moved to the location required by the user.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
