In this way, when the tower crane slowly lifts the lifting tool upwards, the support rods can play a supporting and limiting role for the pallet and the building blocks on the pallet, so that the tower crane can lift the building blocks in the lifting tool to the specified position. After lifting to the specified position, the support rods are removed from the lower frame, and then the tool is lifted by the tower crane, and at this time the building blocks remain in place.
[0007] The lifting tool of the utility model can not only realize the lifting of the block bricks, but also, due to the arrangement of the first telescopic part, the second telescopic part and the fixed part on the upper frame and the lower frame of the utility model, the size of the entire lifting tool can be adjusted, and can be adjusted accordingly according to the overall size specifications of the stacked block bricks. In this way, according to actual needs and the size specifications of the stacked block bricks, the size of the lifting tool can be adjusted by sliding the first telescopic part and the second telescopic part. The lifting tool of the utility model has a wide range of applications, and the same lifting tool can meet the needs of stacked block bricks of different sizes.

[0018] Furthermore, pin holes are provided at both ends of the support rod, and pin shafts can be inserted into the pin holes at both ends of the support rod on the support frame to fix the support rod.
[0019] Beneficial effect: In this solution, pin holes are provided at both ends of the support rod to facilitate fixing the two ends of the support rod, so that the connection between the support rod and the lower frame is stable, which can prevent the support rod from slipping and causing danger during lifting.
[0020] Furthermore, a pin hole is formed at one end of the support rod, and a connecting plate is connected to the other end of the support rod, wherein the width of the connecting plate is greater than the width of the through hole of the support frame.
[0021] Beneficial effect: In this solution, a pin hole is only provided at one end of the support rod, and a connecting plate is used at the other end. Since the width of the connecting plate is greater than the width of the through hole on the support frame, when the support rod is inserted into the support frame, it is only necessary to insert the pin shaft into the position with the pin hole on the support rod to limit the position, which can improve the efficiency of installing the support rod.
[0022] Furthermore, a pull ring is connected to the connecting plate.

The four support frames 7 on both sides of the lower frame 3 are symmetrically arranged with each other, and the four support rods 5 are inserted into the four support frames 7 on both sides of the lower frame 3 in sequence. Both ends of the support rods 5 have a limiting structure to prevent the support rods 5 from sliding off the support frames 7, and the support frames 7 on both sides of the lower frame 3 support the support rods 5.
[0039] In this embodiment, a pin hole is provided at one end of the support rod 5, and a connecting plate 801 is welded to the other end of the support rod 5. The arrangement of the pin hole and the connecting plate in this embodiment forms a limiting structure for limiting the support rod 7.

[0047] Step 4: Open the cotter pin and the pin shaft 9 on the support rod 5 at the bottom of the lifting tool, and pull out multiple support rods 5 from the support frame 7 on the lower frame 3 in turn. Then, slowly lift the lifting tool by the tower crane and lift it above the height of the bricks. Then, insert the support rod 5 on the lower frame 3, insert the pin shaft 9 into one end of the support rod 5 to fix it, and then carry out the next lifting operation.
[0048] Step 5: Adjust the overall width of the lifting tooling according to the requirements and the specifications of the stacking: adjust the position of the first telescopic part 201 and the second telescopic part 203 by stretching the upper frame 2 and the lower frame 3, so as to adjust the width of the lifting tooling. After adjusting the position of the first telescopic part 201 and the second telescopic part 203, fix it by inserting the pin 6 into the socket.
