Specifically, it is cement concrete, also known as ordinary concrete, which is made by mixing sand and stone as aggregates with water in a certain proportion. It is widely used in civil engineering. In actual use, it usually needs to be transported by conveying pipes.

[0003] If concrete remains in the pipeline for too long during transportation, it can easily cause blockage. To address this, we propose a concrete delivery pipe for building construction. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This concrete conveying pipe for building construction is equipped with a conveying structure. A motor drives a rotating shaft to rotate, which in turn drives a bevel gear set to rotate, causing a second rotating shaft to rotate. This causes the auger blades to start rotating, conveying the concrete inside the conveying pipe body. At the same time, the auger blades can scrape off the concrete adhering to the inner wall of the conveying pipe body, cleaning it and preventing the concrete from solidifying and sticking to the inside of the conveying pipe body, thus avoiding blockage of the conveying pipe body.

During installation, first insert the rotating shaft 2 and auger blade on flange 1 into the conveying pipe body. Pull the handles to both sides, and the moving plate will drive the insertion rod to move outward, causing the limiting plate to move outward and compress the spring. Rotate flange 1 to align the insertion plate with the square groove 2 on the connecting part 1. Release the handles, and under the action of the spring, push the limiting plate inward. The insertion rod and the moving plate will pull the insertion plate inward, and then insert it into the square groove 2, initially fixing flange 1. Finally, bolts will be used to fix flange 1 and connecting part 1 together.

A rotating shaft 33 is rotatably connected inside the fixing frame 31. A motor 32 is fixedly connected to the top of the rotating shaft 33. A bevel gear set 34 is fixedly connected to the bottom of the rotating shaft 33. A rotating shaft 2 35 is fixedly connected to the surface of the bevel gear set 34. A screw conveyor blade 36 is fixedly connected to the surface of the rotating shaft 35. Auxiliary structures 4 are provided on both sides of the flange 2. Each auxiliary structure 4 includes a movable plate 41. A rod 42 is fixedly connected to the surface of the movable plate 41. A spring 43 is sleeved on the outer side of the rod 42. A limit plate 44 is fixedly connected to the surface of the rod 42. A handle 45 is fixedly connected to the surface of the movable plate 41. A plate 46 is fixedly connected to the surface of the movable plate 41. A flange 5 is installed on the surface of the connecting part 12. A fixing frame 51 is fixedly connected to the inner wall of the flange 5. A conveying structure 3 is provided, which drives the rotating shaft via a motor 32. Rotation of flange 1 (33) drives bevel gear set 34 to rotate, which in turn drives shaft 2 (35) to rotate, causing auger blade 36 to start rotating. This transports concrete inside the conveying pipe body 1. Simultaneously, auger blade 36 scrapes off concrete adhering to the inner wall of the conveying pipe body 1, cleaning it and preventing concrete from hardening and sticking inside, thus avoiding blockage. An auxiliary structure 4 is provided. During installation, first insert shaft 2 (35) and auger blade 36 from flange 1 (2) into the conveying pipe body 1, then pull handles 45 to both sides. The moving plate 41 then drives the inserted... The rod 42 moves outward, causing the limiting plate 44 to move outward, compressing the spring 43. The flange 2 is rotated so that the insert plate 46 corresponds to the square groove 2 on the connecting part 11. The handle 45 is released, and the limiting plate 44 is pushed inward by the spring 43. The insert plate 46 is pulled inward by the insert rod 42 and the moving plate 41, and then inserted into the square groove 2 to initially fix the flange 2. Then, the flange 2 and the connecting part 11 are fixed together by bolts. With the auxiliary structure 4, no other machinery or manpower is needed to install the flange 2 and the conveying structure 3, making the installation more convenient.

[0024] Furthermore, flange 12 has a mounting groove 1 on its surface. Flange 12 is fixedly connected to connecting part 11 by bolts and mounting groove 1. Flange 25 has a mounting groove 2 on its surface. Flange 25 is fixedly connected to connecting part 22 by bolts and mounting groove 2. The connection between flange 12, connecting part 11, flange 25 and connecting part 22 is tight.

[0025] Furthermore, the motor 32 is fixedly connected to the side surface of the flange 2, and the rotating shaft 33 passes through one side of the flange 2 and is fixedly connected to the output end of the motor 32. The motor 32 drives the rotating shaft 33 to rotate, thereby driving the bevel gear set 34.

[0026] Furthermore, the bevel gear set 34 includes bevel gear one and bevel gear two. Bevel gear one is fixedly connected to shaft one 33, and bevel gear one and bevel gear two mesh with each other. Bevel gear two is fixedly connected to shaft two 35. One end of shaft two 35 near the fixed frame two 51 is rotatably connected inside the fixed frame two 51. The rotation of shaft one 33 drives bevel gear one to rotate. Bevel gear one and bevel gear two mesh with each other, thereby driving shaft two 35 to rotate through bevel gear two, driving the auger blade 36 to rotate.

[0027] Furthermore, the outer surface of the auger blade 36 contacts the inner wall of the conveying pipe body 1. The rotation of the auger blade 36 can scrape the inner wall of the conveying pipe body 1 and scrape off the adhered and solidified concrete.

[0028] Furthermore, circular grooves are provided on both sides of flange 2, and the insertion rod 42 is slidably connected in the circular grooves. A square groove is provided on the side of the circular groove near the center of flange 2, and the limiting plate 44 is slidably connected in the square groove. The two ends of the spring 43 are fixedly connected to the surface of the limiting plate 44 and the inner wall of the square groove, respectively. The limiting plate 44 ensures that the limiting plate 44, the spring 43 and the insertion rod 42 will not move out of the square groove when the handle 45 is pulled outward.

[0029] Furthermore, square grooves are provided on both sides of the connecting part 11, and the insert plate 46 is inserted into the square grooves. The flange 2 is initially fixed by inserting the insert plate 46 into the square grooves.

[0030] Working principle: During installation, first insert the rotating shaft 35 and auger blade 36 on flange 12 into the conveying pipe body 1. Pull the handle 45 to both sides, and the moving plate 41 will drive the insertion rod 42 to move outward, causing the limiting plate 44 to move outward and compress the spring 43. Rotate flange 12 to align the insertion plate 46 with the square groove 2 on the connecting part 11. Release the handle 45, and under the action of the spring 43, push the limiting plate 44 inward. The insertion rod 42 and the moving plate 41 will pull the insertion plate 46 inward, thus inserting it into the square groove 2. Inside, flange 2 is initially fixed, and then flange 2 and connecting part 11 are fixed together with bolts. Motor 32 drives shaft 33 to rotate, which in turn drives bevel gear set 34 to rotate, which in turn drives shaft 35 to rotate, so that auger blade 36 starts to rotate, conveying concrete inside the conveying pipe body 1. At the same time, auger blade 36 can scrape off the concrete adhering to the inner wall of the conveying pipe body 1, clean it, and prevent concrete from solidifying and adhering to the inside of the conveying pipe body 1, thus avoiding blockage of the conveying pipe body 1.
