[0002] In the construction of traditional support systems, dropping devices such as sand boxes or jacks are often used to facilitate the later removal of formwork. The traditional sand box has a low load-bearing capacity. To increase the bearing capacity, the wall thickness of the sand box needs to be increased, resulting in an increase in the overall weight of the sand box. There is no connection between the sand box and the steel pipe column and the distribution beam, and the position of the sand box and the steel pipe column is not centered, resulting in adverse factors such as eccentric compression.
[0003] The traditional sand box is directly placed on the top of the steel pipe column and supports the bottom of the distribution beam through a cylinder plug. However, due to the imperfect overall structure of the traditional sand box, when the sand box placed on the top of the steel pipe column supports the distribution beam, the position where the sand box is connected to the top of the steel pipe column will not be centered. At this time, the support of the cylinder plug to the distribution beam will be eccentric and the force will be uneven. Therefore, it is urgent to improve a dropping device for steel pipes to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a dropping device for steel pipes. The four groups of connection holes opened on the top of the bottom plate are connected to the top of the steel pipe column through bolts. At this time, the cylinder body will not be eccentric at the top of the steel pipe column. When the top core cover plate contacts the bottom of the distribution beam, a group of limiting plates will be respectively placed on both sides of the distribution beam. At this time, the limiting plates limit the distribution beam, thereby preventing the uneven force on the top of the cylinder plug by the distribution beam.
[0005] To achieve the above purpose, the main technical solutions adopted by the utility model include: a dropping device for steel pipes, including a cylinder body and a cylinder plug. The bottom of the cylinder body is provided with a bottom plate. The cylinder plug is placed inside the cylinder body. Suspension lugs are welded on both the left and right sides of the cylinder plug. Stiffening rings are correspondingly arranged inside the suspension lugs.

A group of limiting plates are inserted into the top of the top core cover plate. Clamping plates are connected to the inner sides of a group of the limiting plates.
[0006] Preferably, a group of limiting grooves are opened on the top of the top core cover plate, and the bottom of the limiting plates is connected to the inside of the limiting grooves. Four groups of connection holes are opened around the top of the bottom plate. Drainage holes are opened on both the left and right sides of the cylinder body, and flange nuts are welded outside the drainage holes. Flange bolts are connected in a matching manner inside the flange nuts.
[0007] Preferably, the top of the flange bolt corresponds to the bottom of the stiffening ring.

Specific embodiments
[0021] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.
[0022] As Figures 1 - 6 shown, a falling device for steel pipes provided in this embodiment includes a cylinder body 1 and a cylinder plug 7. A bottom plate 2 is provided at the bottom of the cylinder body 1. The cylinder plug 7 is placed inside the cylinder body 1. Lifting lugs 5 are welded on both the left and right sides of the cylinder plug 7. Stiffening rings 6 are correspondingly arranged inside the lifting lugs 5. The stiffening rings 6 are welded on the outer side of the cylinder body 1. A top core cover plate 8 is fixedly connected to the top of the cylinder plug 7. A group of limit plates 9 are inserted into the top of the top core cover plate 8. Clamping plates 901 are connected to the inner sides of the group of limit plates 9.
[0023] As Figure 1 and Figure 2 shown, further, a group of limit grooves are provided at the top of the top core cover plate 8, and the bottom of the limit plate 9 is connected to the inside of the limit groove. In this way, the limit plate 9 can limit the distribution beam, so that the limit plate 9 will not shake on the top of the top core cover plate 8. Four groups of connection holes are provided around the top of the bottom plate 2. This is beneficial for the bottom plate 2 to be connected to the top of the steel pipe column through bolts. Drainage holes are provided on both the left and right sides of the cylinder body 1, and flange nuts 3 are welded outside the drainage holes. Flange bolts 4 are connected in a matching manner inside the flange nuts 3. In this way, it is convenient to drain the dry sand inside the cylinder body 1 by removing the flange bolts 4, so that the cylinder plug 7 can complete the falling.
[0024] As Figure 3As shown, further, the top of the flange bolt 4 corresponds to the bottom of the stiffening ring 6, which facilitates the removal of the flange bolt 4. Dry sand is injected into the interior of the cylinder body 1, and the top of the dry sand supports the bottom of the cylinder plug 7. This method supports the cylinder plug 7 through the dry sand and at the same time prevents the cylinder plug 7 from sliding down when supporting the distribution beam. C40 concrete is poured into the interior of the cylinder plug 7, which increases the weight of the cylinder plug 7, thus facilitating the extrusion of the dry sand inside the cylinder body 1 and being conducive to the discharge of the dry sand. The top of the bottom plate 2 is welded to the bottom of the cylinder body 1, which facilitates the connection of the bottom plate 2 to the bottom of the cylinder body 1.
[0025] As Figure 4 shown, further, a chute is provided inside the inner side of the limiting plate 9, and the interior of the chute is adapted to the exterior of the clamping plate 901. This method facilitates the coincidence of the clamping plate 901 and the limiting plate 9 and is conducive to a set of limiting plates 9 being respectively placed on both sides of the distribution beam to limit the distribution beam through the limiting plate 9. One side of the clamping plate 901 is rotatably connected to a lead screw 904, and the end of the lead screw 904 is inserted with a hand disc 905. A moving groove is provided on the outer side of the limiting plate 9, and the moving groove penetrates outside the lead screw 904. This method rotates the lead screw 904 to push the clamping plate 901 to clamp the distribution beam. A set of limiting grooves are provided on the outside of the limiting plate 9, and a stabilizing plate 902 penetrates through the interior of each set of limiting grooves. One end of the stabilizing plate 902 is welded to the outer side of the clamping plate 901. This method prevents the clamping plate 901 from rotating when the clamping plate 901 moves towards the distribution beam. A limiting block is provided at the end of the stabilizing plate 902 away from the connected clamping plate 901, which prevents the stabilizing plate 902 from detaching from the interior of the limiting plate 9.
[0026] As Figure 5 shown, a moving block 903 is slidably connected to the interior of the limiting plate 9 through the moving groove, which facilitates the upward movement of the clamping plate 901 and can adjust the height of the clamping plate 901. Internal threads are provided inside the moving block 903, and the internal threads match the exterior of the lead screw 904, which facilitates the lead screw 904 to push the clamping plate 901 to move. A set of sliding rods 906 penetrate through the top of the moving block 903. The bottoms of each set of sliding rods 906 are fixedly connected to a support block 907, and support blocks 907 are provided at the tops of each set of sliding rods 906. The ends of the support block 907 and the connecting block 908 are welded to the outer side of the limiting plate 9, which increases the stability of the upward movement of the moving block 903 through the sliding rods 906.
[0027] As Figures 1 - 6As shown in the figure, the principle of a falling device for steel pipes provided in this embodiment is as follows: First, four groups of connection holes opened at the top of the bottom plate 2 are connected to the top of the steel pipe column through bolts. At this time, the cylinder body 1 will not be eccentric at the top of the steel pipe column, which facilitates the cylinder plug 7 to support the bottom of the distribution beam through the top core cover plate 8. When the top core cover plate 8 contacts the bottom of the distribution beam, a group of limit plates 9 at the top of the top core cover plate 8 will be respectively placed on both sides of the distribution beam. At this time, the limit plates 9 limit the distribution beam, thereby preventing uneven force on the top of the cylinder plug 7 by the distribution beam. By rotating the hand disk 905 to drive the screw rod 904 to rotate, the moving block 903 is connected to the screw rod 904 through the internally threaded opening. One end of the screw rod 904 is rotatably connected to the outside of the clamping plate 901. At this time, by rotating the screw rod 904, the clamping block can be pushed towards the distribution beam, so that the clamping plate 901 can clamp the distribution beam, which is beneficial to fixing the distribution beam.
