DETAILED DESCRIPTION

[0041] The following specific embodiments illustrate the embodiments of the utility model, and those skilled in the art can easily understand other advantages and effects of the utility model from the disclosed content of the specification, obviously, the described embodiments are a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0042] Please refer to Figures 1-8 Now a kind of pier formwork installation dismantling lifting appliance disclosed by the utility model will be described, the utility model has five parts, as shown in Figure 1 Including connecting bolt 1, limiting assembly 2, connecting piece 3, limiting plug -in rod 4 and connecting lifting ring 5, connecting lifting ring 5 bottom installs limiting plug -in rod 4, and connecting space is formed between limiting plug -in rod 4 and connecting lifting ring 5, and connecting piece 3 upper end is arranged in connecting space, limiting plug -in rod 4 passes through connecting piece 3, connecting bolt 1 is installed at the bottom of connecting piece 3, and the bottom of connecting bolt 1 passes through the bottom plate of connecting piece 3, and the bottom end of connecting bolt 1 is installed with limiting assembly 2.

[0043] In use, this utility model involves taking the connecting ring 5 with the limiting rod 4, then rotating the limiting rod 4. This drives the column 41 and the displacement rotating rod 45 to rotate, causing the column 41 to leave the threaded hole 52. Then, the limiting rod 4 is pulled to the left. During this pulling process, the push spring 42 is compressed, and a gap is created between the column 41 and the right connecting ring 53 as the column 41 moves. The upper end of the connector 3 is then inserted along the gap, and the column 41 is aligned with the connecting hole 34. The limiting rod 4 is then released. Under the elastic force of the push spring 42, the displacement rotating rod 45 is driven to move to the right and reset. Finally, the right end of the column 41 rests against the left surface of the right connecting ring 53. Then, the baffle 43 is rotated, which drives the displacement rotating rod 45 and the column 41 to rotate. With the cooperation of the first external thread 46 and the threaded hole 52, the column 41 is inserted into the connecting ring 53. After this process is completed, the push spring 42 will be fully extended and will not generate any elastic force. When the column 41 is unscrewed, the push spring 42 twists and generates elastic force. When the column 41 is just unscrewed, under the action of elastic force, the column 41 will abut against the left surface of the right connecting ring 53. Then, the connecting bolt 1 is inserted into the placement plate 33, and the limiting component 2 is screwed into the bottom of the connecting bolt 1. Then, the template to be spliced ​​is taken out. In the initial state, under the action of the return spring 26, the limiting component 2 rotates the top block 24 outward, so that the entire limiting component 2 presents a flower-shaped structure. When the limiting component 2 passes through the template side hole, the rotating top block 24 needs to be deflected and sent back to the flipping groove 23. At this time, the limiting component 2 presents a columnar structure, so that the limiting component 2 can pass through the template side hole. When the rotating top block 24 flips into the flipping groove 23, the return spring 26 presents a compression tendency. When the limiting component 2 passes through the template side hole, under the action of the return spring 26, the rotating top block 24 is driven to flip outward. The flipped rotating top block 24 can form a support ring, such as Figure 8 As shown, the support ring is placed at the bottom of the side plate of the template to lift the template. The wire rope on the crane is wrapped around the connecting ring 5, and finally the template is lifted by the crane and sent to the installation position. After the template is sent to the installation position, the rotating top block 24 is pressed back into the flipping groove 23, so that the entire limiting component 2 is pulled out from the side hole of the template for the next hoisting. In the entire connection process between the template and the lifting device, no tools are used and no bolts are tightened. This not only effectively improves the assembly speed of the template and the lifting device and improves the construction progress, but also reduces labor costs. The structure itself is easy to assemble and has a wide range of applications.

[0044] In a specific embodiment, such as Figures 2-3The limiting assembly 2 comprises a round hole 21, an internal thread structure 22, a turnover groove 23, a rotating top block 24, a rod body 25, a reset spring 26, a rotating rod 27 and a insertion hole 28. The round hole 21 is formed on the upper surface of the rod body 25 and extends to the lower part of the rod body 25. The internal thread structure 22 is arranged on the surface of the round hole 21. The turnover grooves 23 are arranged on the side surface of the rod body 25 and extend to the upper surface of the rod body 25. The insertion holes 28 are arranged in pairs on the side wall of the turnover groove 23. The rotating rod 27 is rotatably connected in the insertion hole 28. The rotating top block 24 is installed between the two rotating rods 27. The reset spring 26 is sleeved outside the rotating rod 27. The two ends of the reset spring 26 are respectively installed on the side wall of the rotating top block 24 and the inner wall of the turnover groove 23. The whole limiting assembly 2 can be selected according to the side hole of the template. Generally, the size of the side hole of the template is the same as the diameter of the rod body 25, or the diameter is slightly larger than the diameter of the rod body 25. Under the arrangement of the rotating top block 24, the rotating top block 24 will be resisted on the bottom surface of the plate body on the side of the side hole of the template after being turned over. In most cases, the spreader does not need to be removed when the spreader is spliced with the template. The limiting assembly 2 can directly pass through the side hole of the template. In special cases, the side plate of the template is wider, the distance between the top surface of the limiting assembly 2 and the bottom surface of the placing plate 33 is smaller than the thickness of the side plate of the template. At this time, the limiting assembly 2 needs to be removed during installation, then the bottom of the connecting bolt 1 passes through the side hole of the template, and then the limiting assembly 2 is installed. The purpose of the round hole 21 is to arrange the internal thread structure 22. The internal thread structure 22 can be matched with the second external thread 11 to realize the connection between the connecting bolt 1 and the limiting assembly 2. The turnover groove 23 is used for placing the rotating top block 24 which needs to be accommodated. The rotating rod 27 can drive the rotating top block 24 to turn over. The reset spring 26 is used to provide power for the rotation of the rotating rod 27. A limiting block is arranged on the rotating rod 27 and a limiting groove is formed on the side wall of the insertion hole 28 to make the limiting block turn over and limit the continuous movement of the limiting block. If the limiting block cannot continue to move, the rotating top block 24 can be kept at a certain angle, as shown in Figure 2 In order to realize that the rotating top block 24 can automatically return after being turned over to the turnover groove 23, the reset spring 26 will be compressed again when the rotating top block 24 moves to the turnover groove 23. In order to achieve better supporting effect, the reset spring 26 is also in the compressed state when the rotating top block 24 is not in the turnover groove 23. At this time, the elastic force of the reset spring 26 still drives the rotating top block 24 to turn over. The limiting block and the limiting groove are used to limit the turning over of the rotating top block 24 at this time. Moreover, due to the elastic effect of the reset spring 26, the reset spring 26 can always keep the rotating top block 24 at the outermost position, so that the template side plate has the best supporting effect. The gravity of the template is evenly distributed on each rotating top block 24, which has better supporting effect and longer service life. Through the limiting assembly 2, the spreader has a wider range of use.

The ring body 51 is used for winding the steel wire rope, the threaded hole 52 is used for connecting the limiting plug rod 4, so that the limiting plug rod 4 is not easy to produce translation on the connecting ring 53, and the connecting area between the connecting lifting ring 5 and the limiting plug rod 4 is increased, which can better share the gravity, and the circular baffle 54 can limit the outward movement of the limiting plug rod 4, so that the limiting plug rod 4 is clamped in the connecting lifting ring 5. Therefore, it is not necessary to pull out the limiting plug rod 4 every time the lifting appliance is assembled, which effectively reduces the assembly time of the lifting appliance and speeds up the construction efficiency.

[0046] In one specific embodiment, as Figure 5 , the limiting plug rod 4 comprises a column body 41, a propelling spring 42, a baffle 43, a connecting plate 44, a displacement rotary rod 45 and a first external thread 46, the baffle 43 is installed on the left end surface of the displacement rotary rod 45, the column body 41 is installed on the right end surface of the displacement rotary rod 45, the first external thread 46 is arranged on the outer surface of the column body 41, the column body 41 is inserted into the threaded hole 52, the displacement rotary rod 45 is drivingly connected in the circular baffle 54, the connecting plate 44 is sleeved outside the displacement rotary rod 45, the connecting plate 44 is drivingly connected in the left connecting ring 53, the propelling spring 42 is sleeved outside the displacement rotary rod 45, and the propelling spring 42 is installed between the right end of the circular baffle 54 and the left end of the connecting plate 44. The first external thread 46 is used for cooperating with the threaded hole 52, the propelling spring 42 is used for providing power to the connecting plate 44, when the displacement rotary rod 45 moves outward, the propelling spring 42 is compressed to generate elastic force, after the displacement rotary rod 45 is loosened, the elastic force of the propelling spring 42 drives the connecting plate 44 to displace rightward, and the displacement rotary rod 45 moves rightward, at this time, the column body 41 is pushed to the right connecting ring 53. In this way, the limiting plug rod 4 can be connected with the connecting lifting ring 5 quickly without disassembly, the abutment of the limiting plug rod 4 and the connecting lifting ring 5 is not necessary every time in the prior art, the problem of misalignment is avoided, and the bolt and the nut are not used in the product, so that the cumbersome tightening mode is avoided.
