Bolt connection, the two moving blocks 10 on the two threaded rods 5 have opposite thread directions, a baffle 11 is provided on the top of the connecting plate 7, and an insert block 12 is fixedly connected to the bottom of the baffle 11, and the insert block 12 passes through the through groove and is slidably connected to the through groove, and two insert rods 13 are fixedly connected to the bottom of the baffle 11, and the two insert rods 13 pass through the two circular grooves respectively and extend to the inside of the circular tube 9, and a pressure plate 14 is fixedly connected to one side of the baffle 11, and a stabilizing groove 15 is opened on one side of the pressure plate 14, and a stabilizing plate 16 is embedded in the inside of the stabilizing groove 15, and the stabilizing plate 16 is slidably connected to the stabilizing groove 15 and extends to the outside of the stabilizing groove 15, and a plurality of springs 17 are fixedly connected to one side of the stabilizing plate 16, and one side of the plurality of springs 17 are fixedly connected to the inner wall of the stabilizing groove 15, and an anti-slip pad is fixedly connected to the other side of the stabilizing plate 16;

[0029] In order to achieve the purpose of making the two threaded rods 5 move in the same direction at the same time, the device adopts the following technical solution: a sprocket 18 is fixedly sleeved on the outer sides of the two threaded rods 5, a chain 19 is arranged inside the transverse groove 6 and extends to the outside of the transverse groove 6, the chain 19 is sleeved on the two sprockets 18, and the two sprockets 18 are connected by the chain 19, and a hand wheel is fixedly connected to one side of one of the threaded rods 5;

[0030] Among them, in order to achieve the purpose of lifting concrete blocks, the present device adopts the following technical solutions: a fixed plate is provided between the two vertical plates 3, two baffle rods 20 are fixedly connected on both sides of the fixed plate, one end of the two baffle rods 20 is fixedly connected to one side of the vertical plate 3, a support plate 21 is provided on the top of the horizontal plate 2, two pull rods 22 are fixedly connected on both sides of the support plate 21, one end of the two pull rods 22 is fixedly connected to the top of the two vertical plates 3, and a pull ring is fixedly connected to the top of the support plate 21.

[0031] The use process of the utility model is as follows: when it is necessary to lift the concrete block, first pull the baffle plate 11 upwards and move the baffle plate 11 to move the plug block 12 and the plug rod 13. At the same time, the movement of the baffle plate 11 will cause the pressure plate 14, the stabilizing plate 16 and the anti-slip pad to move upwards. Then use tools to remove the bolts and move the round tube 9 and the connecting plate out of the top of the base plate 1. Then you can move the concrete block to the base plate 1 and place it. After the placement is completed, first fix the connecting plate and the round tube 9 with bolts, then move the connecting plate 7 to align the round groove with the round tube 9, and then pass the plug rod 13 through the round groove and insert it into the inside of the round tube 9.

Then turn the hand wheel, the hand wheel rotates and causes one of the threaded rods 5 to rotate, and the other threaded rod 5 is rotated through the sprocket 18 and the chain 19. The thread directions of the two moving blocks 10 are opposite, and under the limitation of the plug rod 13, the round tube 9 and the connecting plate 7, the threaded rod 5 rotates to move the moving block 10, and the movement of the moving block 10 drives the connecting plate to move and drives the round tube 9, the plug rod 13, the connecting plate 7, the plug block 12 and the baffle 11 to move. The movement of the baffle 11 drives the pressure plate 14 to move, and the movement of the pressure plate 14 causes the stabilizing plate 16, the spring 17 and the anti-slip pad to move. When the anti-slip pad contacts the concrete block, the pressure plate 14 and the stabilizing plate 16 still have a certain amount of movement space under the action of the spring 17, and the spring 17 is squeezed at the same time. The reaction force generated by the spring 17 makes the stabilizing plate 16 and the anti-slip pad contact with the concrete block more closely, thereby fixing the concrete block, and then the hook is put in the pull ring and through the support plate 21, the pull rod 22, the vertical plate 3 and the bottom plate 1, so that the crane can lift it.
