One end of each guide rod is fixedly mounted with a moving block.
[0007] Preferably, a support plate is fixedly mounted on the fixed block, and an operating block is fixedly mounted on the support plate. The operating block has a rotating cavity inside, and traction cavities are symmetrically arranged on the rotating cavity. A threaded sleeve is movably mounted on the rotating cavity. One end of the threaded sleeve passes through the operating block, and a traction block is fixedly mounted on one end of the threaded sleeve.

After the cement solidifies to form a precast wall panel, a cylinder is activated. Under the action of the piston rod, one of the movable blocks moves along two guide rods. The adjusting block and the rhomboid block cause the two movable blocks to move in opposite directions along the guide rods. The rhomboid block rotates on the assembly rod, causing the movable block to move the extension rod on the connecting rod. The extension rod then moves the guide rod on the traction rod, which in turn moves the movable block. Simultaneously, the rhomboid block drives the first equal-diameter bevel gear on the fixed tube to rotate, which in turn drives the second equal-diameter bevel gear to rotate. This causes the transmission screw to rotate within the threaded sleeve, allowing the sliding block on the threaded sleeve to move within the traction chamber. The threaded sleeve then moves the traction block, facilitating the demolding of the precast wall panel and improving work efficiency. Attached Figure Description

An extension rod 71 is fixedly mounted on one end of each connecting rod 70, a traction rod 72 is fixedly mounted on one end of each extension rod 71, a guide rod 73 is fixedly mounted on one end of each traction rod 72, and a movable block 13 is fixedly mounted on one end of each guide rod 73. When the starting cylinder 42 is activated, under the action of the piston rod 43, one of the movable blocks 41... The two moving blocks 41 move on the two guide rods 33. Under the action of the adjusting block 52 and the rhomboid block 32, the two moving blocks 41 move in opposite directions on the guide rods 33. The rhomboid block 32 rotates on the assembly rod 31, driving the first equal-diameter bevel gear 60 on the fixed tube 53 to rotate. At the same time, the moving blocks 41 drive the extension rod 71 on the connecting rod 70 to move. The extension rod 71 drives the guide rod 73 on the traction rod 72 to move. The guide rod 73 drives the movable block 13 to move.
[0031] Reference Figure 1 and Figure 4A support plate 23 is fixedly mounted on the fixed block 22, and an operating block 30 is fixedly mounted on the support plate 23. The operating block 30 has a rotating cavity 80 inside, and traction cavities 81 are symmetrically arranged on the rotating cavity 80. A threaded sleeve rod 61 is movably mounted on the rotating cavity 80. One end of the threaded sleeve rod 61 movably passes through the operating block 30, and a traction block 12 is fixedly mounted on one end of the threaded sleeve rod 61. The traction block 12 is located on one side of the two movable blocks 13. Sliding blocks 82 that move within the traction cavity 81 are symmetrically fixedly mounted on the surface of the threaded sleeve rod 61. A sliding block 82 that moves within the threaded sleeve rod 61 is movably mounted on the rotating cavity 80. A threaded transmission screw 62 is used for threaded assembly. One end of the transmission screw 62 movably passes through the operating block 30, and a second equal diameter bevel gear 63 is fixedly assembled at one end of the transmission screw 62 to be threaded with the first equal diameter bevel gear 60. When the rhomboid block 32 rotates, it drives the first equal diameter bevel gear 60 on the fixed tube 53 to rotate. The first equal diameter bevel gear 60 drives the second equal diameter bevel gear 63 to rotate, so that the transmission screw 62 rotates in the threaded sleeve 61, and the sliding block 82 on the threaded sleeve 61 moves in the traction cavity 81. The threaded sleeve 61 drives the traction block 12 to move.
[0032] Reference Figure 1 and Figure 2 A base block 83 is fixedly mounted on the support frame 10, and a stop block 11 is fixedly mounted on the base block 83. Two movable blocks 13 and a traction block 12 are respectively attached to the end face of the base block 83. The stop block 11, the traction block 12, and the movable block 13 are attached to each other. Cement is poured into the base block 83 so that the cement is located between the stop block 11, the traction block 12, and the movable block 13. After the cement solidifies to form a precast wall panel, the two movable blocks 13 and the traction block 12 are pulled to move, which facilitates the demolding of the precast wall panel and improves work efficiency.
[0033] Working principle: Cement is poured onto the base block 83, positioning it between the stop block 11, the traction block 12, and the movable block 13. After the cement solidifies to form a precast wall panel, the cylinder 42 is activated. Under the action of the piston rod 43, one of the movable blocks 41 moves along the two guide rods 33. Under the action of the adjusting block 52 and the rhomboid block 32, the two movable blocks 41 move in opposite directions along the guide rods 33. The rhomboid block 32 rotates on the assembly rod 31. The movable block 41 drives the extension rod 71 on the connecting rod 70 to move... The extension rod 71 moves the guide rod 73 on the traction rod 72, which in turn moves the movable block 13. At the same time, the rhomboid block 32 drives the first equal diameter bevel gear 60 on the fixed tube 53 to rotate, which in turn drives the second equal diameter bevel gear 63 to rotate. This causes the transmission screw 62 to rotate in the threaded sleeve 61, which in turn causes the sliding block 82 on the threaded sleeve 61 to move in the traction cavity 81. The threaded sleeve 61 then drives the traction block 12 to move, facilitating the demolding of precast wall panels and improving work efficiency.
