[0028] like Figure 3 - Figure 4 As shown, there are two limit frames 2. Each limit frame 2 includes a sliding frame 21. A movable block 22 is fixedly installed at the bottom of the sliding frame 21. A side plate 23 is fixedly installed at the top of the sliding frame 21. Multiple support plates 24 are fixedly installed on one side of each side plate 23. A reinforcing bracket 25 is fixedly installed between the bottom of the support plate 24 and the side plate 23. The two movable blocks 22 are respectively threaded onto both ends of the bidirectional screw 13. The two sliding frames 21 are respectively slidably installed inside the sliding grooves 18 on both sides.

[0029] Rotating the rotating rod 14 causes the sliding frames 21 at both ends of the fixed plate 11 to slide inside the sliding groove 18 through the rotation of the double screw 13. Under the action of the rotating rod 14 and the double screw 13, the side plates 23 on both sides move closer and further apart. The support plates 24 at both ends support the bottom ends of the precast concrete component, so that the device can be adapted to precast concrete components of different sizes.

[0035] In use, depending on the size of the precast concrete component, by rotating the rotating rod 14, the bidirectional screw 13 rotates inside the bottom block 12, and the moving blocks 22 at both ends move towards each other or in opposite directions. The sliding frame 21 moves in the sliding groove 18 inside the fixed plate 11, and the position of the two side support plates 24 is adjusted. When the precast concrete component is placed on top of the support plate 24, the space between the precast concrete component and the fixed plate 11 is used to facilitate the handling of the precast concrete component and the fixed frame 1.

[0036] Before moving the fixed frame 1 and the precast concrete component as a whole, the pressing block 34 is lowered by rotating the fastening screw 33. The pressing blocks 34 at both ends press on the top of the precast concrete component to fix the precast concrete component on the top of the support plate 24, so as to prevent the fixed frame 1 and the precast concrete component from shaking during the transportation and improve the stability of the transportation of the precast concrete component.
