[0031] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to describe in detail the specific implementation manners, structures, features and their effects of the present invention as follows.

[0032] Example 1: Please refer to Figures 1-3 As shown in the figure, the purpose of this embodiment is to provide a lightweight cushion pier structure that is convenient for forklift placement, including a temporary support cushion pier 8 and a handling tool 7 for forklifting the temporary support cushion pier 8. The temporary support cushion pier 8 includes a cross support pier. Anti-overturning rib plates 10 are arranged in a circular array at the center of the top of the cross support pier, and a circular gap formed by several anti-overturning rib plates 10 is used to install a temporary support pipe 9;

[0033] Among them, the cross support pier is welded by I-shaped supports that intersect vertically and horizontally. The I-shaped support includes a bottom plate 1 and a top plate 3. The bottom plate 1 and the top plate 3 are fixedly connected by a web 2, and several reinforcing rib plates 4 are arranged on the side wall of the web 2.

[0034] Preferably, the bottom plate 1, the top plate 3, and the web 2 are all made of carbon steel plates, and the forklift sleeve 5 and the tooling buckle 6 are also made of carbon steel plates.

[0035] Furthermore, the array radius of several anti-overturning rib plates 10 is adapted to the outer diameter of the temporary support pipe 9, and the temporary support pipe 9 is fixedly installed in the circular gap at the center of the top of the cross support pier.

[0036] In this embodiment, the reinforcing rib plates 4 are fixedly arranged on the side wall of the web 2. Several reinforcing rib plates 4 are regularly arranged on the side wall of the web 2. The top of the reinforcing rib plate 4 is in close contact with the top plate 3, and the bottom of the reinforcing rib plate 4 is in close contact with the bottom plate 1. The reinforcing rib plate 4 can also be used as a limit plate for the tooling buckle 6 to prevent the temporary support cushion pier 8 from slipping.

[0037] In this embodiment, the forklift handling tool 7 includes a forklift sleeve 5. Two tooling buckles 6 are fixedly arranged on the lower surface of the forklift sleeve 5, and the tooling buckles 6 are inclined at 15 - 75° on the lower surface of the forklift sleeve 5. Preferably, the tooling buckle 6 is inclined at 45°. At this time, as Figure 3 shown in the figure, the tooling buckle 6 can just be aligned with the forklift sleeve 5.

[0038] Among them, the forklift sleeve 5 is formed by enclosing and welding several steel plates. A fork slot for the forklift to insert, which is formed by enclosing several steel plates, penetrates through the side wall of the forklift sleeve 5. The length of the forklift sleeve 5 is greater than the length of the midpoint of two adjacent bottom plates 1, which is convenient for the forklift sleeve 5 to adapt to temporary support cushion piers 8 of different lengths, so that it has a larger adaptation range. When the length of the forklift sleeve 5 is the same as the length of the midpoint of two adjacent bottom plates 1, at this time, the forklift sleeve 5 can just be stuck into the midpoint of the bottom plate 1. At this time, the temporary support cushion pier 8 can be stably transported.

[0039] And the tooling buckle 6 is L-shaped, and a reinforcing rib plate is fixedly arranged on the side wall of the tooling buckle 6. The reinforcing rib plate is used to increase the stability of the tooling buckle 6. The two tooling buckles 6 are symmetrically arranged on the lower surface of the forklift sleeve 5 near the two ends of the edge, which is convenient for the tooling buckle 6 to clamp the forklift sleeve 5 more stably.

[0040] Embodiment 2: As shown in Figure 4 the figure, in this embodiment, the reinforcing rib plates 4 are slidably arranged. A plurality of reinforcing rib plates 4 are slidably arranged on the side wall of the web 2, and positioning bolts 41 are threadedly installed through the reinforcing rib plates 4. By tightening the positioning bolts 41, the reinforcing rib plates 4 are positioned. The top of the reinforcing rib plates 4 is closely attached to the top plate 3, and the bottom of the reinforcing rib plates 4 is closely attached to the bottom plate 1;

[0041] and the width of the reinforcing rib plates 4 is less than 1 / 2 of the width of the bottom plate 1, that is, the reinforcing rib plates 4 retract into the space area formed by the bottom plate 1 and the top plate 3. When the positioning bolts 41 are in an untightened state, one end of the positioning bolts 41 will not be exposed outside the I-shaped support;

[0042] Specifically, a T-shaped limiting groove 21 is formed on the side wall of the web 2. One end of the reinforcing rib plate 4 is fixedly provided with a T-shaped limiting block adapted to the T-shaped limiting groove 21, and the T-shaped limiting block is slidably clamped in the T-shaped limiting groove 21 to realize the sliding adjustment of the reinforcing rib plate 4 on the side wall of the web 2. A threaded hole is formed through the reinforcing rib plate 4, and the positioning bolt 41 is threadedly installed in the threaded hole. When one end of the positioning bolt 41 abuts against the side wall of the web 2, the fixing of the reinforcing rib plate 4 at the position on the side wall of the web 2 can be realized.

[0043] Among them, the slidable reinforcing rib plate 4 serves as a limiting plate for the tooling buckle 6. The positions of two adjacent reinforcing rib plates 4 are adjusted according to the position of the tooling buckle 6 to prevent the temporary support cushion pier 8 from sliding, thereby ensuring the stability of the temporary support cushion pier 8 during placement.

[0044] Embodiment 3: The present invention provides a placement method for a lightweight cushion pier structure facilitating forklift placement, which is used for placing the above-mentioned lightweight cushion pier structure facilitating forklift placement, including the following steps:

[0045] S1. Place the bottom plate 1 on a horizontal plane, weld the web 2 to the bottom plate 1, arrange the reinforcing rib plates 4 between the bottom plate 1 and the web 2, and weld the top plate 3 to the upper ends of the web 2 and the reinforcing rib plates 4 to complete the prefabrication of the temporary support cushion pier 8;

[0046] S2. Prefabricate the fork sleeve 5 and the tooling buckle with carbon steel plates and weld them together to form the forklift transfer tooling 7;

[0047] S3. The forklift inserts the fork into the fork sleeve 5 and moves the fork to drive the forklift transfer tooling 7 to directly above the temporary support cushion pier 8;

[0048] S4. The forklift slowly lowers the fork and stops when the tooling buckle 6 is slightly lower than the top plate of the temporary support cushion pier 8. Then the fork moves slowly to both sides until the tooling buckle 6 is closely attached to the edge of the top plate 3 of the temporary support cushion pier 8;

[0049] S5. The forklift raises the fork, drives the temporary support cushion pier 8 to move to the designated position through the forklift transfer tooling 7, lowers the fork, and the temporary support cushion pier 8 contacts the ground;

[0050] S6. The forklift slowly moves the fork towards the middle. When the forklift transfer tooling 7 is in close contact, raise the fork upward, and the transfer of the temporary support cushion pier 8 is completed;

[0051] S7. Install the temporary support pipe 9 and the anti-overturning rib plate 10 on the temporary support cushion pier 8, and the installation of the temporary support is completed.
