[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] See also Figures 1 to 4 The present application proposes a pouring device for precast concrete components, including a support plate 20, a fixed cylinder 15, a barrier cylinder 12, a pouring part 4 and a plastering part 5. The support plate 20 has legs 17 and is connected to an outer cylinder 3. The lower end surface of the fixed cylinder 15 is connected to the support plate 20. The fixed cylinder 15 is located inside the outer cylinder 3 and is concentrically arranged with the outer cylinder 3, so that the surface of the support plate 20 located between the outer cylinder 3 and the inner cylinder is an annular surface. The distance between the upper end surface of the fixed cylinder 15 and the support plate 20 is greater than the distance between the upper end surface of the outer cylinder 3 and the support plate 20. The fixed cylinder 15 is provided with a mounting cylinder 11 fixedly connected to its inner wall. The barrier cylinder 12 is arranged on the support plate 20 and is located inside the fixed cylinder 15. The barrier cylinder 12 is provided with a conveying pipe 10 rotatably connected to the mounting cylinder 11, and the upper end of the conveying pipe 10 passes through the mounting cylinder 11, and the lower end passes through the support plate 20. The outer wall of the conveying tube 10 is provided with a thread groove 101, the outer peripheral wall of the barrier tube 12 is movably sleeved with a first cylindrical airbag 14, the first cylindrical airbag 14 is connected to a first air pump, the first cylindrical airbag 14 is slidably connected to the inner peripheral wall of the fixed tube 15, the upper end surface of the first cylindrical airbag 14 is connected to a driving tube 13 movably arranged inside the fixed tube 15, and the inner wall of the driving tube 13 is provided with a driving rod 131 inserted into the thread groove 101. One end of the casting part 4 is provided with a clamping plate 24 extending along its length direction, and the upper end of the conveying tube 10 is detachably connected with a fixing seat 26 and a fixing block 25, and the fixing seat 26 is rotatably connected to the clamping plate 24. The fixing block 25 is provided with a clamping groove extending in the horizontal direction, and the clamping groove cooperates with the clamping plate 24. The casting part 4 is provided with a discharge port, and the interior of the casting part 4 has a cavity, the cavity connects the conveying pipe 10 and the discharge port, and the plastering part 5 is connected to the casting part 4 so that the upper end surface of the prefabricated pipe can be smoothed when the casting part 4 rotates.

[0030] In the embodiment provided by the present application, when it is necessary to cast a prefabricated concrete pipe, the feed pipe on the concrete transport vehicle can be rotated and connected to the end of the delivery pipe 10 that passes through the support plate 20. When the feed pipe delivers concrete to the delivery pipe 10, the first tubular airbag 14 is expanded by the first air pump, and the first tubular airbag 14 moves upward in the fixed cylinder 15, that is, moves in the direction away from the support plate 20. When the first tubular airbag 14 moves, it will drive the drive pipe 13 connected thereto to move upward, and then the drive rod 131 inserted into the thread groove 101 will move upward to drive the delivery pipe 10 to rotate. When the delivery pipe 10 rotates, it will drive the casting part 4 to rotate, and while the casting part 4 rotates, it will transport concrete to between the fixed cylinder 15 and the outer cylinder 3 and form a prefabricated pipe. There is no need to set the casting part 4 outside the outer cylinder 3 and pour concrete between the outer cylinder 3 and the fixed cylinder 15, saving the site or space occupied during the casting work.

[0031] When the upper end surface of the prefabricated pipe is flush with the upper end surface of the outer tube 3, the feeding pipe stops conveying concrete, and the pouring part 4 still rotates and drives the plastering part 5 to move on the upper end surface of the prefabricated pipe to smooth the upper end surface of the prefabricated pipe, thereby improving the molding quality of the prefabricated pipe. The first air pump can make the first cylindrical airbag 14 expand and contract back and forth, and when the first cylindrical airbag 14 contracts, it drives the driving pipe 13 to move downward, thereby causing the conveying pipe 10 to rotate in the opposite direction. In this way, the plastering part 5 can move back and forth on the upper end surface of the prefabricated pipe, and the upper end surface of the prefabricated pipe can be smoothed in both directions, thereby further improving the molding quality of the prefabricated pipe.

[0032] Part of the conveying pipe 10 is in the barrier tube 12, that is, the part of the conveying pipe 10 with the thread groove 101 extends upward from the barrier tube. The part of the conveying pipe 10 in the barrier tube has a certain distance from the inner wall of the barrier tube, that is, the conveying pipe 10 does not contact the inner wall of the barrier tube. By arranging the first cylindrical airbag 14 in the fixed tube 15, the central axis of the first cylindrical airbag 14 can coincide with the central axis of the driving tube 13, and the driving tube 13 can be moved up and down by the expansion and contraction of the first cylindrical airbag 14. There is no need to arrange a fixed tube 15 with a larger diameter to adapt to other driving devices, which saves the space occupied by the fixed tube 15, facilitates the casting of prefabricated tubes with smaller diameters, and facilitates the casting of prefabricated tubes with thicker wall thicknesses when the spacing between the outer tube 3 and the fixed tube 15 remains unchanged, and can further save the space occupied by the casting equipment of the concrete prefabricated components.

[0033] Since the fixed cylinder 15 and the outer cylinder 3 are in an upright state, concrete needs to be poured from a high place. In order to facilitate the connection of the feeding pipe, the legs 17 are connected to the support plate 20 to support the support plate 20 and space the support plate 20 from the horizontal plane where the bottom of the legs 17 is located. In this way, the delivery pipe 10 can extend downward after passing through the support plate 20, and the staff can connect the feeding pipe to the lowest part of the delivery pipe 10, without connecting the feeding pipe from a high place or moving the feeding pipe to a high place, which facilitates the pouring of concrete.

[0034] When the prefabricated pipe needs to be taken out, the pouring part 4 in the horizontal state is pulled upward, and the clamping plate 24 on the pouring part 4 rotates and disengages from the clamping groove. As the clamping plate 24 rotates, the pouring part 4 can be rotated to a vertical position, and then the prefabricated pipe can be pulled out upward. Of course, the prefabricated pipe can also be directly pulled upward. When the prefabricated pipe moves upward, it will touch the pouring part 4 and push the pouring part 4 to rotate upward to a vertical state. As the prefabricated pipe moves upward, the prefabricated pipe will be taken out. When the width of the pouring part 4 is large and blocks the upward movement of the prefabricated pipe, the fixing seat 26 can be removed, and then the pouring part 4 can be removed, and then the prefabricated pipe can be taken out upward; when the size of the fixing block 25 affects the removal of the prefabricated pipe, the fixing block 25 can be removed.

[0035] In some embodiments of this application, please refer to Figure 2 A second cylindrical airbag 8 is fixedly sleeved on the outer wall of the fixed cylinder 15, and the second cylindrical airbag 8 is connected to a second air pump. The distance between the upper end surface of the second cylindrical airbag 8 and the support plate 20 is greater than the distance between the upper end surface of the outer cylinder 3 and the support plate 20. The outer wall of the second cylindrical airbag 8 is covered with a metal elastic plate 1, and the lower surface of the metal elastic plate 1 is slidably connected to the support plate 20.

[0036] The second air pump can expand and contract the second cylindrical airbag 8. When the second cylindrical airbag 8 expands, it will drive the metal elastic plate 1 to approach the outer tube 3. Then, the second cylindrical airbag 8 is kept in the expanded state, and concrete can be poured between the metal elastic plate 1 and the outer tube 3 to form a prefabricated tube with a larger diameter or a thinner wall. When the second cylindrical airbag 8 contracts, the metal elastic plate 1 will also contract. After the contraction stops, concrete can be poured between the metal elastic plate 1 and the outer tube 3 to form a prefabricated tube with a smaller diameter or a thicker wall. In this way, prefabricated tubes with different diameters or different wall thicknesses can be cast.

[0037] In order to cast prefabricated pipes of different lengths, in some embodiments of the present application, please refer to Figure 5The two ends of the leg 17 are connected to the inner bottom wall of the support plate 20 and the seat body 18 respectively. The leg 17 is arranged in a cylindrical shape, and the central axis of the leg 17 coincides with the central axis of the delivery pipe 10. The outer peripheral wall of the leg 17 is movably sleeved with a third cylindrical airbag 7, the third cylindrical airbag 7 is slidably connected to the inner side wall of the seat body 18, the third cylindrical airbag 7 is connected to a third air pump, and the upper end surface of the third cylindrical airbag 7 is connected to an annular pad 6 movably sleeved on the outer peripheral wall of the leg 17. The upper end of the outer tube 3 is connected to the annular fixed body 2, and the lower end is connected to the annular pad 6. The inner peripheral wall of the outer tube 3 abuts against the peripheral side wall of the support plate 20. The top of the seat body 18 is fixedly connected to the first telescopic rod 16, and the end of the first telescopic rod 16 away from the seat body 18 is fixedly connected to the annular fixed body 2. A connecting pipe 19 is provided at the lower end of the delivery pipe 10 and extends into the interior of the supporting leg 17 and passes through the bottom wall of the seat body 18 . The seat body 18 is provided with a support to support the seat body 18 .

[0038] The third cylindrical airbag 7 is controlled to expand by the third air pump. After the third cylindrical airbag 7 expands, the outer tube 3 on the annular pad 6 will move upward. The upward movement of the outer tube 3 will push the annular fixing plate and extend the first telescopic rod 16. The setting of the annular fixing plate and the first telescopic rod 16 will prevent the outer tube 3 from deflecting or tipping during the movement, so that the outer tube 3 moves more stably and maintains the inner circumferential wall of the outer tube 3 and the outer circumferential wall of the support plate 20. After the outer tube 3 moves upward for a certain distance, the feeding pipe can be rotated and connected to the connecting pipe 19 to pour concrete between the outer tube 3 and the metal elastic plate 1 and form a longer prefabricated pipe. The third air pump controls the third cylindrical airbag 7 to shrink, and the outer tube 3 will move downward. Pouring concrete between the outer tube 3 and the metal elastic plate 1 can form a shorter prefabricated pipe.

[0039] It can be understood that one end of the connecting tube 19 is rotatably connected to the conveying tube 10, and the other end is fixedly connected to the bottom wall of the seat body 18. In this way, the load on the conveying tube 10 during rotation can be reduced, and the part of the connecting tube 19 extending out of the bottom wall of the seat body 18 can be prevented from rotating, thereby preventing the rotation of the conveying tube 10 from being affected by the outside world.

[0040] See also Figure 6 , the connection pipe 19 is provided with an annular scraper 23 that contacts the inner circumferential wall of the connection pipe 19, and the annular scraper 23 is connected to a plurality of third elastic members arranged at intervals along its circumference, and one end of the third elastic member away from the annular scraper 23 is connected to the inner wall of the connection pipe 19. In this way, when concrete passes through the connection pipe 19, the annular scraper 23 moves up and the third elastic member is in a stretched state. When the pouring is completed, the annular scraper 23 continuously slides up and down under the action of the third elastic member and scrapes off the residue in the connection pipe 19, reducing the possibility of blockage.

[0041] In order to facilitate the demoulding and removal of the prefabricated tube, in some embodiments of the present application, refer to Figure 5 and Figure 7The outer cylinder 3 includes a plurality of elastic sealing plates 32 and a plurality of movable plates 31. The two ends of the elastic sealing plate 32 are respectively slidably connected to the annular fixed plate and the annular pad 6. The two adjacent movable plates 31 are connected by the elastic sealing plate 32. The movable plates 31 and the elastic sealing plate 32 are both arranged in an arc shape. The movable plate 31 is fixedly connected to the first elastic member. The end of the first elastic member away from the movable plate 31 abuts against the inner wall of the seat body 18. The two ends of the movable plate 31 are respectively slidably connected to the annular fixed plate and the annular pad 6. Among them, the annular pad 6 is provided with a spherical airbag 21 and a plurality of guide seats corresponding to the plurality of movable plates 31. The spherical airbag 21 is connected to the fourth air pump. The guide seat is provided with a guide hole. A push piece is movably inserted in the guide hole. The two ends of the push piece abut against the movable plate 31 and the spherical airbag 21.

[0042] When the prefabricated tube needs to be taken out, the fourth air pump expands the spherical airbag 21. After the spherical airbag 21 expands, the push piece pushes the movable plate 31 outward. The movable plate 31 moves away from the prefabricated tube and compresses the first elastic member. The movable plate 31 moves and pulls the elastic sealing plate 32 away from the prefabricated tube. At this time, the second air pump can be used to shrink the second cylindrical airbag 8 and the metal elastic plate 1 and move them away from the prefabricated tube. In this way, the prefabricated tube can be separated from the outer tube 3 and the metal elastic plate 1, making it easier to take out.

[0043] In order to improve the fit between the inner wall of the outer tube 3 and the outer wall of the support plate 20, prevent the leakage of concrete, and improve the fit between the bottom surface of the metal elastic plate 1 and the upper surface of the support plate 20, prevent the concrete from entering between the metal elastic plate 1 and the surface of the support plate 20 and affecting the molding quality of the prefabricated pipe. In some embodiments of the present application, the interior of the support plate 20 is filled with a first magnetic fluid, the interior of the movable plate 31 and the interior of the elastic sealing plate 32 are both provided with a second magnetic fluid that can be magnetically attracted to the first magnetic fluid, and the material of the metal elastic plate 1 is a magnetic material.

[0044] The magnetism of the first magnetic fluid and the second magnetic fluid is relatively weak, and the first magnetic fluid can not only magnetically attract the metal elastic plate 1, improve the fit between the bottom surface of the metal elastic plate 1 and the upper surface of the support disk 20, but also have little effect on the relative sliding between the metal elastic plate 1 and the support disk 20. The second magnetic fluid can not only magnetically attract the first magnetic fluid, improve the fit between the inner wall of the outer cylinder 3 and the outer wall of the support disk 20, but also have little effect on the relative sliding between the inner wall of the outer cylinder 3 and the outer wall of the support disk 20.

[0045] In order to enable the pouring part 4 to pour concrete evenly, in some embodiments of the present application, please refer to Figure 8The casting part 4 includes a casting shell 41 and a bellows 42. The casting shell 41 has a cavity, and is provided with a plurality of discharge ports arranged at intervals along its length direction. A through hole 4121 is provided on the surface of the casting shell 41 away from the discharge port and two support frames 30 are installed. The two support frames 30 are connected to each other through a mounting rod 29. The through hole 4121 and the mounting rod 29 extend along the length direction of the casting shell 41. The support frame 30 away from the conveying pipe 10 is provided with a through hole. One end of the bellows 42 is connected to the conveying pipe 10, and the other end extends into the cavity and is installed with a pull plate 28. The end of the pull plate 28 away from the bellows 42 passes through the through hole 4121 and is movably sleeved on the mounting rod 29. The pull plate 28 is fixed with a pull rope 27, and the pull rope 27 passes through the through hole.

[0046] When pouring a prefabricated pipe with a thicker pipe wall, the staff can pull the pull rope 27 below to slide the pull plate 28 on the mounting rod 29, and the sliding of the pull plate 28 will extend the bellows 42. The first cylindrical air bag 14 can be slowly rotated by the first air pump, thereby slowly rotating the pouring part 4. The staff can walk around the outer tube 3 and continuously pull and release the pull rope 27, thereby continuously extending and shortening the bellows 42 as the pouring shell 41 rotates, so that the concrete flowing out of the bellows 42 falls evenly to the area to be poured.

[0047] It is understandable that a pulley and a guide tube are provided at one end of the casting shell 41 away from the conveying pipe 10, the guide tube extends in the vertical direction, and one end of the pull rope 27 passing through the through hole is wound around the pulley and passes through the guide tube. In this way, it is convenient to pull the pull rope 27 and guide the pull rope 27.

[0048] In order to enable the pouring part 4 to pour concrete uniformly while saving manpower, in some embodiments of the present application, the pouring shell 41 includes two first main body plates 411, a second main body plate 412 and a transverse plate 413. The two sides of the second main body plate 412 are respectively connected to the two first main body plates 411, and the second main body plate 412 is provided with a through hole 4121. The two ends of the transverse plate 413 are respectively connected to the two first main body plates 411, and the transverse plate 413 is configured as a plurality of transverse plates 413, and the plurality of transverse plates 413 are arranged at intervals along the length direction of the second main body plate 412, and a discharge port is formed between two adjacent transverse plates 413. The lower surfaces of the plurality of transverse plates 413 are provided with columnar air bags, and the end surfaces at the two ends of the columnar air bags are respectively slidably connected to the two adjacent side surfaces of the two first main body plates 411, and the columnar air bags are connected to a fifth air pump. Among them, a cavity is formed between the two first main body plates 411, the second main body plate 412 and the plurality of transverse plates 413.

[0049] The fifth air pump is used to expand and contract the multiple columnar airbags in sequence, that is, the columnar airbags close to the bellows 42 expand first, until the columnar airbags farther from the bellows 42 expand, and then the columnar airbags farther from the bellows 42 contract first. In this way, after the two adjacent columnar airbags expand, the two columnar airbags abut against each other, and the concrete output by the bellows 42 cannot fall between the two columnar airbags, but can only flow in the direction of the unexpanded columnar airbag. The reciprocating expansion and contraction of the multiple columnar airbags can make the concrete output by the bellows 42 flow back and forth in the thickness direction of the prefabricated pipe wall, so that the concrete pouring is more uniform.

[0050] In order to smooth the upper end surface of prefabricated pipes of different lengths, in some embodiments of the present application, the plastering unit 5 includes a sliding block 51, a second telescopic rod 52, a mounting body 53 and a wiping member 54. The sliding block 51 is movably arranged on the annular fixed body 2, and one end of the second telescopic rod 52 is connected to the sliding block 51. The mounting body 53 is fixed to the outer wall of the casting shell 41, and a columnar groove is provided in the mounting body 53, which cooperates with the other end of the second telescopic rod 52. The wiping member 54 is connected to the sliding block 51 and is located between the metal elastic plate 1 and the outer tube 3, and the bottom surface of the wiping member 54 is flush with the upper end surface of the outer tube 3.

[0051] When a longer prefabricated pipe needs to be cast, the other end of the second telescopic rod 52 is inserted into the columnar groove to move the outer tube 3 upward and the annular fixing plate upward, thereby shortening the second telescopic rod 52 on the sliding block 51. When the casting shell 41 rotates, the second telescopic rod 52 drives the slider to slide around the metal elastic plate 1 on the annular fixing body 2, thereby causing the wiping member 54 to slide on the upper end surface of the prefabricated pipe and smooth the upper end surface of the prefabricated pipe, thereby improving the molding quality of the prefabricated pipe.

[0052] For prefabricated pipes of different diameters, in order to enable the wiping member 54 to smooth most of the upper end surface of the prefabricated pipe, in some embodiments of the present application, the wiping member 54 includes a plurality of scrapers 541. Two adjacent scrapers 541 are slidably connected, a second elastic member is provided between the two adjacent scrapers 541, the scrapers 541 close to the outer tube 3 among the plurality of scrapers 541 are connected to the sliding block 51, the scrapers 541 away from the outer tube 3 abut against the metal elastic plate 1, and the bottom surfaces of the plurality of scrapers 541 are all flush with the upper end surface of the outer tube 3.

[0053] When the second cylindrical airbag 8 expands, the metal elastic plate 1 pushes the scraper 541 close to it to move and overlap with the adjacent scraper 541. When the second cylindrical airbag 8 contracts, the second elastic member separates the two overlapping scrapers 541. In this way, it can adapt to prefabricated pipes of different diameters and smooth most of the upper end surface of the prefabricated pipe.

[0054] The scraper 541 includes a plate body 5411 and a scraper, a connecting tube is provided at the bottom of the plate body 5411, a connecting column is provided at the top of the scraper, the connecting column is slidably connected in the connecting tube, a fourth elastic member is provided inside the connecting tube, and both ends of the fourth elastic member are respectively connected to the plate body 5411 and the connecting column, so that when the bottom surface of the scraper is flush with the upper end surface of the outer tube 3, the connecting column compresses the fourth elastic member. In this way, the scraper will keep pressing the upper end surface of the prefabricated pipe during the movement of the upper end surface of the prefabricated pipe, thereby improving the leveling effect, and can also improve the density of the concrete surface on the prefabricated pipe and reduce bubbles.

[0055] When the wiping piece 54 is tilted to wipe the concrete, the concrete can be scraped more evenly. In order to ensure that the wiping piece 54 can still tilt and scrape the upper end surface of the prefabricated pipe when the casting part 4 rotates back and forth, in some embodiments of the present application, two wiping pieces 54 are configured, and the bottom surfaces of the two wiping pieces 54 are both tilted. A sliding seat 35 is movably provided on the annular fixed plate, and a rotating shaft 34 is rotatably installed on the sliding seat 35. One end of the rotating shaft 34 is fixedly connected to the two wiping pieces 54, and the other end is fixedly connected to the pulling body 33. The pulling body 33 is provided with a strip hole 331. The sliding block 51 is fixedly connected to the plug column 511, and the plug column 511 is movably connected to the strip hole 331, so that when the plug column 511 moves to the end of the strip hole 331, one of the two wiping pieces 54 can be in a vertical state, and the lowest part of its bottom surface is flush with the upper end surface of the outer tube 3.

[0056] When the sliding block 51 slides on the annular fixed body 2, the plug post 511 moves in the strip hole 331. The moving process of the plug post 511 will cause the pulling body 33 to rotate. When the pulling body 33 rotates, the rotating shaft 34 will rotate, thereby causing one of the two wiping members 54 to rotate to a vertical state. When the plug post 511 moves to the end of the strip hole 331, one of the two wiping members 54 is in a vertical state. As the sliding block 51 continues to move, the sliding seat 35 will be driven to move. When the sliding seat 35 moves, one of the two wiping members 54 is still in a vertical state. Since the bottom surface of the wiping member 54 is inclined, the wiping member 54 in a vertical state will move under the drive of the sliding seat 35 and obliquely scrape the upper end surface of the prefabricated pipe. When the sliding block 51 moves in the opposite direction, one of the two wiping members 54 will be turned away from the vertical state. The other of the two wiping members 54 will gradually rotate to a vertical state and move in the opposite direction driven by the slide 35, thereby also being able to obliquely scrape the upper end surface of the prefabricated pipe.

[0057] Working principle: When in use, the first cylindrical airbag 14 is inflated by the first air pump, and the first cylindrical airbag 14 moves upward in the fixed tube 15, that is, moves in the direction away from the support plate 20. When the first cylindrical airbag 14 moves, it will drive the driving tube 13 connected thereto to move upward, and then the driving rod 131 inserted into the threaded groove 101 will move upward to drive the conveying tube 10 to rotate. When the conveying tube 10 rotates, it will drive the casting part 4 to rotate. When the casting part 4 rotates, concrete will be conveyed between the fixed tube 15 and the outer tube 3. When the upper end surface of the prefabricated tube is flush with the upper end surface of the outer tube 3, the concrete delivery is stopped, and the casting part 4 still rotates and drives the plastering part 5 to move on the upper end surface of the prefabricated tube and smooth the upper end surface of the prefabricated tube.
