[0023] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.
[0024] Please also read Figures 1 to 3 The steam hole blocking prevention structure provided by the utility model is now described. The steam hole blocking prevention structure comprises an arc plate 1, a connecting plate 3 and a connecting bolt 4. The arc plate 1 is used to coaxially fit with the steam pipe 2 to block one of the steam holes 21 on the steam pipe 2. The connecting plate 3 is located on the side of the arc plate 1 away from the steam pipe 2, and the connecting plate 3 is connected to the steam pipe 2. The connecting plate 3 is provided with a threaded hole, and the hole depth direction of the threaded hole faces the arc plate 1. The screw of the connecting bolt 4 is threadedly connected in the threaded hole, so that the connecting bolt 4 can squeeze the arc plate 1 in the direction of the steam pipe 2.
[0025] Compared with the prior art, the steam hole blocking prevention structure provided by the utility model has a connection bolt 4 threadedly connected to the connection plate 3 to press the arc plate 1 in the direction of the steam pipe 2, so that the arc plate 1 fits and presses the steam pipe 2, thereby blocking a steam hole 21 on the steam pipe 2. When curing starts after pouring, the connection bolt 4 is driven to rotate away from the arc plate 1, and then the arc plate 1 is driven to move in a direction away from the steam pipe 2, thereby opening the blocked steam hole 21. Therefore, the blocking of the steam hole 21 by the arc plate 1 can avoid the problem that the steam hole 21 on the steam pipe 2 may be blocked by impurities such as spilled concrete.
[0026] In some embodiments, see Figure 2 The steam hole blocking prevention structure further includes a fixed shaft 5. The fixed shaft 5 and the arc plate 1 are located on the same side of the steam pipe 2, the fixed shaft 5 is fixed on the steam pipe 2, and the fixed shaft 5 is connected to the connecting plate 3. The connecting plate 3 is connected to the steam pipe 2 through the fixed shaft 5.
[0027] In some embodiments, see Figure 2 and Figure 3 The fixed shaft 5 is parallel to the axis of the steam hole 21 blocked by the arc plate 1, the connecting plate 3 is perpendicular to the fixed shaft 5, the connecting plate 3 is in a long strip shape, one end of the connecting plate 3 in the length direction is rotatably connected to the fixed shaft 5, and the other end is used to set a threaded hole. When the arc plate 1 opens the steam hole 21, the connecting plate 3 is driven to rotate to a suitable position, so as to avoid the connecting plate 3 blocking the steam flowing out of the steam hole 21.
[0028] In some embodiments, see Figure 2 One end of the connecting plate 3 in the length direction can be rotatably sleeved on the fixed shaft 5, and the steam hole blocking prevention structure also includes a limit ring 6. There are two limit rings 6, which are sleeved and fixed on the fixed shaft 5, and the two limit rings 6 abut against the connecting plate 3 from both sides. The two limit rings 6 can limit the axial movement of the connecting plate 3 along the fixed shaft 5, so that the connecting plate 3 only has the freedom of rotation, thereby realizing the rotation connection between the connecting plate 3 and the fixed shaft 5.
[0029] In some embodiments, see Figure 2 and Figure 3 The arc plate 1 is slidably connected to the connecting plate 3, so that the arc plate 1 can approach or move away from the steam pipe 2. When the arc plate 1 slides away from the steam pipe 2 to open the steam hole 21, the connecting plate 3 drives the arc plate 1 to rotate, so that the arc plate 1 reaches the side of the fixed shaft 5 away from the opened steam hole 21, and then the arc plate 1 and the steam pipe 2 are slidably fitted, and then the connecting bolts 4 are driven to press the arc plate 1. At this time, the arc plate 1 and the connecting plate 3 will not block the steam flowing out of the opened steam hole 21.
[0030] In some embodiments, see Figure 2The steam hole blocking prevention structure further includes a connecting rod 7. The connecting rod 7 is parallel to the fixed shaft 5, and the connecting rod 7 slides through the connecting plate 3 and is fixedly connected to the arc plate 1. The arc plate 1 is slidably connected to the connecting plate 3 through the connecting rod 7.
[0031] In some embodiments, see Figure 2 The side surface of the connecting rod 7 has a stopper 71 protruding outward, and the stopper 71 is located on the side of the connecting plate 3 away from the arc-shaped plate 1. In this way, the connecting rod 7 can be prevented from sliding off the connecting plate 3.
[0032] In some embodiments, see Figure 2 , the cross section of the connecting rod 7 is rectangular. In this way, the arc plate 1 and the connecting rod 7 can be restricted from rotating, so that the arc plate 1 can be easily aligned with the steam pipe 2 coaxially.
[0033] Based on the same inventive concept, an embodiment of the present application also provides a steam pipe, which is provided with a plurality of steam holes 21, and each steam hole 21 is provided with the above-mentioned steam hole anti-blocking structure, so that the problem that the steam holes 21 on the steam pipe 2 may be blocked by impurities such as spilled concrete can be avoided.
[0034] In some embodiments, a heat-insulating layer is disposed outside the steam pipe 2 to prevent the steam pipe 2 from dissipating heat, thereby preventing the steam in the steam pipe 2 from condensing and then liquefying.
[0035] Furthermore, an electric heating rod is fixedly disposed in the fixed shaft 5. After the heat generated by the electric heating rod is conducted to the steam pipe 2, the steam in the steam pipe 2 can be prevented from condensing and liquefying as much as possible.
[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
