Description

Technical Field

[0001] The invention relates to the technical field of concrete pipe pile curing and molding, in particular to a concrete pipe pile hardening and molding device. Background Art

[0002] Concrete pipe piles are a type of structural element commonly used in foundation engineering, usually to support the foundation of a building or other engineering structure. They are usually cylindrical in shape, made of concrete, and can be customized with different diameters and lengths as needed. Concrete pipe piles can be divided into different types according to their design and purpose, including ordinary concrete pipe piles and prestressed concrete pipe piles. During the construction process, concrete pipe piles are buried deep underground or underwater, and provide stable support and bearing capacity through their own weight and / or through the reinforcement of prestressing technology to support the safety and stability of buildings or other important structures.

[0003] The production process of concrete pipe piles includes key steps such as mold preparation, concrete preparation, pouring, centrifugal forming, maintenance, mold removal and quality inspection. First, select a suitable mold according to the design, and pour the concrete slurry into the mold to ensure full filling and uniform distribution; then, put the mold into a centrifuge for centrifugal rotation so that the concrete in the mold forms a hollow tube under centrifugation. Subsequently, sufficient maintenance is carried out to promote the development of concrete strength. After the concrete reaches the designed strength, the mold is removed and quality inspection is carried out to ensure that it meets the standard requirements.

[0004] According to the existing production process steps of concrete pipe piles, it is not difficult to see that the concrete in the mold needs to be centrifugally rotated before steam curing. These two steps are cumbersome and time-consuming, which seriously affects the production efficiency of concrete pipe piles. In addition, when the concrete pipe piles after centrifugal molding are placed in the hardening molding device as the mold is placed, it is inevitable that the concrete in the mold will vibrate, thereby causing the hollow tubular part of the concrete in the mold to deform, etc., affecting the quality of the concrete pipe piles after molding.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 9 As shown, the present invention includes the following embodiments:

[0033] Embodiment 1, a concrete pipe pile hardening and forming device, comprises a horizontally placed tank body 1 and an end cover 2 at the opening of the tank body 1; a steam generator 3 connected to the inside of the tank body 1 is provided at one end of the tank body 1 away from the end cover 2; the hardening and forming device is controlled and operated by a controller; a first motor 4 is provided at one end of the inside of the tank body 1 away from the end cover 2; the output shaft of the first motor 4 is fixedly connected to a driving gear 41; a perforated plate 5 is provided on the inner wall of the tank body 1; a forming cylinder 6 is passed through and rotatably connected to the rotating hole 51 on the perforated plate 5; the forming cylinder 6 opens toward the end cover 2; the forming cylinder 6 is fixedly connected to a driven gear 61 at one end away from the end cover 2; the driven gear 61 is meshed with the driving gear 41; the first motor 4 can drive the forming cylinder 6 to rotate in the tank body 1.

[0034] In this embodiment, the lower outer wall of the horizontally placed tank body 1 is hingedly connected to a fixed seat 11 and a lifting seat 12; the fixed seat 11 is arranged at a position close to the end cover 2; the lifting seat 12 is arranged at a position away from the end cover 2; the lifting seat 12 can drive the tank body 1 to lift up one end away from the end cover 2 under the control of the controller.

[0035] In this embodiment, a strip-shaped drainage groove 21 is provided on the inner side of the end cover 2; a plurality of the drainage grooves 21 cross and pass through the inner center of the end cover 2; a drain valve 13 is provided at the lower position of the inner wall of the tank body 1; the drain valve 13 is provided close to the end cover 2; there are multiple orifice plates 5; the orifice plates 5 are in sealing contact with the tank body 1; the orifice plates 5 are rotatably and sealingly connected with the forming cylinder 6; one of the orifice plates 5 forms a drainage cavity 52 close to the end cover 2; and the drain valve 13 is connected to the drainage cavity 52.

[0036] During operation, the staff first mixes and prepares the concrete, weaves the steel cage and puts it into the mold, pours the concrete slurry into the mold and then closes the mold, then transfers the mold filled with concrete to one side of the hardening molding device, then opens the end cover 2 at the opening of the tank body 1, and uses a crane or other feeding equipment to allow the mold with concrete to enter along the opening of the forming cylinder 6, and the mold will enter the interior of the forming cylinder 6, then close the end cover 2 at the opening of the tank body 1, start the controller to control the steam generator 3 to pass steam into the forming cylinder 6, so that the mold with concrete is oxidized by steam in the corresponding forming cylinder 6, and the space in the tank body 1 is divided into multiple spaces by the forming cylinder 6, and the inner wall of the forming cylinder 6 is adapted to the outer wall of the mold, so that the injection of steam into the forming cylinder 6 is faster than injecting steam into the tank body 1, and there is no waste at the same time. During the operation of the steam generator 3, the controller controls the first motor 4 to work, and the first motor 4 drives the driving gear 41 to rotate. Since the driving gear 41 is meshed with the driven gear 61, the driving gear 41 can drive the driven gear 61 to rotate. During the rotation of the driven gear 61, the forming cylinder 6 is driven to rotate, and during the rotation of the forming cylinder 6, the internal mold is driven to rotate. During the rotation of the mold, the concrete inside is driven to produce a centrifugal effect, so that the concrete in the center of the mold converges toward the inner wall of the mold, so that the concrete in the mold forms a hollow tube. Since multiple forming cylinders 6 are meshed with a single driving gear 41 through corresponding driven gears 61, the driving gear 41 can drive multiple forming cylinders 6 to rotate at the same speed, so that multiple forming cylinders 6 rotate at the same speed. The forming cylinder 6 drives the mold to rotate to complete the centrifugal molding of the concrete. During the rotation of the forming cylinder 6, steam will also pass through the holes on the mold to enter the inside, so as to cure the concrete in the mold. The centrifugally formed concrete in the mold will also be cured and hardened with the passage of time. Since the concrete in the mold is cured during the centrifugal molding process, the centrifugal molding time of the concrete in the mold and the curing molding time have a certain overlap, which greatly reduces the production time of concrete pipe piles and improves the production efficiency of concrete pipe piles.The steam curing time of concrete pipe piles is longer than the centrifugal forming time of concrete, so the concrete can be centrifugally formed in the early stage of steam curing, so it will not affect the forming of the concrete pipe piles. In addition, when the mold rotates with the forming cylinder 6, the forming cylinder 6 and the tank body 1 are both in a horizontal position, so the thickness of the concrete pipe piles is guaranteed to be consistent. After the centrifugal forming of the concrete pipe piles is completed, the controller will control the lifting seat 12 to work. The lifting seat 12 can be understood as a giant hydraulic cylinder, so as to lift the end of the tank body 1 away from the end cover 2. The end of the tank body 1 away from the end cover 2 will be tilted with the fixed seat 11 as the fulcrum. The lower end of the fixed seat 11 is connected to the slide rail, so that the fixed seat 11 can slide on the The fixing seat 11 and the lifting seat 12 move on the rail close to or away from the lifting seat 12. Under the cooperation of the fixing seat 11 and the lifting seat 12, the end of the tank body 1 away from the end cover 2 is higher than the end close to the end cover 2. The forming tube 6 moves with the movement of the end cover 2, so that the end of the forming tube 6 away from the end cover 2 is higher than the end close to the end cover 2, so that the forming tube 6 is tilted, and the mold is also tilted with the tilt of the forming tube 6. The excess water in the center of the concrete in the mold will be tilted and poured out along the hole at the end of the mold. The inner wall of the end cover 2 is provided with a strip-shaped drainage groove 21, so the water flowing out of the hole at the end of the mold enters the drainage groove 21 along the opening of the forming tube 6, and finally flows along the drainage groove 21 to the lower position of the inner wall of the tank body 1, and the waste water will be discharged along the drainage groove 21. The groove 21 flows into the end of the drain valve 13 located on the inner side of the tank body 1, and the wastewater covers the end of the drain valve 13. The drain valve 13 can be set as a pressure relief valve to achieve automatic pressure relief at the corresponding pressure, for example, it is set to 1.0Mpa, and steam is continuously injected into the forming cylinder 6, so that the steam in the forming cylinder 6 overflows from the opening and flows into the drainage cavity 52 in the tank body 1 along the drainage groove 21, so that the pressure of the drainage cavity 52 in the tank body 1 increases. When the air pressure in the drainage cavity 52 in the tank body 1 is higher than 1.0Mpa, the drain valve 13 will be opened, and the wastewater will first flow out along the drain valve 13 until the drain valve 13 flows out to the steam, and the steam injection is stopped, and the drain valve 13 is also closed accordingly. The steam will perform centralized steam curing on the concrete in the mold in the forming cylinder 6. Compared with the steam that needs to fill the entire tank body 1, the waste of steam is greatly avoided. The steam in the drainage cavity 52 occupies a small area, and the waste can be ignored. Then the controller controls the lifting seat 12 to shorten, so that the forming cylinder 6 and the tank body 1 are restored to a horizontal state. During the rotation of the forming cylinder 6, the concrete in the mold is cured and hardened. After the hardening and molding of the concrete pipe pile is completed, the first motor 4 is stopped, and the end cover 2 is opened. The concrete pipe pile connected to the inside of the mold is lifted out from the corresponding inner hook of the forming cylinder 6 and cooperated with the crane. In this way, the hardening and molding of the concrete pipe pile is completed, and the mold can be opened at last.

[0037] The present invention places the mold filled with concrete into the forming cylinder 6 in the tank body 1, so that the concrete in the forming cylinder 6 is steam-cured during the centrifugal forming process, thereby preventing the concrete in the mold from being shaken loose during the process of entering the tank body 1, and saving the concrete pipe pile processing steps, so that the quality and efficiency of the concrete pipe pile are improved;

[0038] The present invention places the mold filled with concrete into the forming cylinder 6 in the tank body 1 for steam curing, thereby greatly reducing the waste of steam compared to the situation where steam is passed into the entire tank body 1, so that the steam can more concentratedly cure the concrete in the mold, thereby improving the concrete hardening effect and efficiency.

[0039] In Example 2, a limiting plate 7 is movably connected inside the molding tube 6; the limiting plate 7 is connected to the inner bottom wall of the molding tube 6 through a first spring 71 on the side facing away from the end cover 2; the first spring 71 can press the mold on the inner side of the molding tube 6 to a position close to the end cover 2.

[0040] In this embodiment, the steam generator 3 is connected to the inner bottom wall of the forming tube 6; the limiting plate 7 is movably sealed and connected to the inner wall of the forming tube 6; the end face of the limiting plate 7 is provided with a through hole 72; a plurality of the through holes 72 are provided with a one-way air inlet valve and a one-way air outlet valve; the limiting plate 7 divides the internal space of the forming tube 6 into a temporary storage chamber and a working chamber; the limiting plate 7 will draw the steam in the working chamber into the temporary storage chamber for temporary storage when approaching the end cover 2.

[0041] During operation, after the end cover 2 is opened, the staff will pass the mold filled with concrete into the molding cylinder 6 along the opening of the molding cylinder 6. In the process of the mold entering the molding cylinder 6, the limiting plate 7 will be squeezed and move close to the inner bottom wall of the molding cylinder 6. The limiting plate 7 needs to overcome the elastic force of the first spring 71, so that the working chamber will be formed and expanded. After the mold completely enters the corresponding molding cylinder 6, the end cover 2 is closed, and then the controller controls the steam generator 3 to pass steam along the steam pipe 33 to the inner bottom wall of the molding cylinder 6, so that the steam fills the temporary storage chamber. The steam in the temporary storage chamber overcomes the one-way air outlet valve and passes through the through hole 72 into the working chamber, so that the working chamber is filled with steam. For molds with holes at both ends or when there is a gap between the outer wall of the mold and the inner wall of the molding cylinder 6, the conditions for steam circulation are met, so that the working chamber can be filled with steam. After completing the centrifugal molding in the mold and the subsequent After the subsequent hardening, since the limiting plate 7 is transmitted to the mold in the forming cylinder 6 under the elastic force of the first spring 71, the mold will not produce axial movement in the forming cylinder 6 under the restriction of the limiting plate 7, so that the mold in the forming cylinder 6 is more stable during centrifugal molding and subsequent hardening, thus meeting the hardening requirements of concrete pipe piles of different lengths. After the concrete pipe piles are hardened, the steam generator 3 is stopped, and the end cover 2 is opened, and then the mold is hooked out of the corresponding forming cylinder 6. In the process of the mold moving away from the inner bottom wall of the forming cylinder 6, the limiting plate 7 will move away from the inner bottom wall of the forming cylinder 6, so that the temporary storage chamber is expanded and the working chamber is reduced. Negative pressure is formed in the process of the expansion of the temporary storage chamber, so that the steam in the working chamber overcomes the one-way air inlet valve and passes through the through hole 72 into the temporary storage chamber for temporary storage. After the new mold enters the forming cylinder 6, the steam in the temporary storage chamber enters the working chamber along the through hole 72, and finally the end cover 2 is closed;

[0042] In this embodiment, the plate 7 is restricted from axially moving in the forming tube 6, so that when the mold is hooked out of the forming tube 6, the steam in the working chamber enters the temporary storage chamber for temporary storage, and after the new mold enters the forming tube 6, the steam in the temporary storage chamber enters the working chamber along the through hole 72 for filling, thereby greatly reducing the waste caused by steam leakage and further improving the hardening molding efficiency.

[0043] Embodiment 3, the center of the plurality of orifice plates 5 passes through and is fixedly connected to the center rod 42; the center rod 42 is fixedly connected to the inner center of the end cover 2 through the second motor 8; the end cover 2 is fixedly connected to the tank body 1; the orifice plates 5 are rotatably sealed and connected to the inner wall of the tank body 1; the forming cylinder 6 can rotate around the center rod 42 while being driven by the first motor 4 and the second motor 8.

[0044] In this embodiment, the side of the steam generator 3 close to the end cover 2 is connected to and fixedly connected to the first swivel 31; the side of the first swivel 31 close to the end cover 2 is rotatably sealed and connected to the second swivel 32; the second swivel 32 is connected to and fixedly connected to the steam pipe 33; one end of the steam pipe 33 extends to the inner bottom wall of the forming cylinder 6, and they are rotatably sealed and connected to each other.

[0045] In this embodiment, a card slot 64 is provided on the inner wall of the forming tube 6; the card slot 64 is distributed on the inner wall of the forming tube 6; a card block 65 is slidably connected in the card slot 64; one end of the card block 65 is connected to the bottom of the card slot 64 through a second spring 66, and the other end of the card block 65 extends to the inner side of the forming tube 6; the other end of the card block 65 is provided with a guide angle 651 in the axial direction of the forming tube 6.

[0046] In this embodiment, a conical hole 22 is provided inside and outside the end cover 2; the aperture of the conical hole 22 away from the orifice plate 5 is larger than the aperture of the end close to the orifice plate 5; a conical plug 23 is covered inside the conical hole 22; and the forming cylinder 6 corresponds to the conical hole 22 after the orifice plate 5 rotates.

[0047] During operation, when it is necessary to harden the concrete, the staff starts the controller to control the second motor 8 to rotate, and the second motor 8 drives the center rod 42 and the hole plate 5 to rotate, and the hole plate 5 drives multiple forming tubes 6 to rotate around the center rod 42, so that the opening of one of the forming tubes 6 is aligned with the tapered hole 22, and the inner diameter of the end of the tapered hole 22 close to the forming tube 6 is adapted to the inner diameter of the forming tube 6, so that the staff can control the mold to enter the forming tube 6 more easily under the guidance of the tapered hole 22, and the other forming tubes 6 are not aligned with the tapered hole 22, so the openings of other forming tubes 6 can be more or less covered. The mold 6 is blocked to reduce the loss of steam. When the mold enters the molding tube 6, the guide angle 651 on the card block 65 is squeezed, and after the mold enters the molding tube 6, part of the card block 65 will extend from the card slot 64 under the action of the second spring 66 and be stuck on the outer wall of the mold, so that the mold will not slip during the subsequent rotation of the molding tube 6. After multiple molding tubes 6 are loaded in sequence, the conical plug 23 is closed, and then the controller is started to control the steam generator 3 to work. The steam generator 3 will send steam into the molding tube 6 along the first rotating ring 31, the second rotating ring 32, and the steam pipe 33. At the same time, the first motor 4 drives the driving gear 41 to rotate, and the second motor 8 and the first motor 4 both rotate in opposite directions. In this way, the driven gear 61 and the driving gear 41 are meshed and transmitted. During the rotation of the hole plate 5, multiple forming cylinders 6 are driven to revolve around the center rod 42. During the revolution of the forming cylinder 6, centrifugal force is generated, causing the concrete to move away from the center rod 42. The forming cylinder 6 drives the corresponding driven gear 61 to mesh with the driving gear 41, so that the driven gear 61 rotates. During the rotation of the driven gear 61, the forming cylinder 6 is driven to rotate. During the rotation of the cylinder 6, the mold stuck by the block 65 will be driven to rotate, so that the mold in the molding cylinder 6 will rotate. The rotation speed of the concrete in the mold is greater than the revolution. This will not affect the centrifugal molding of the concrete in the mold. On the contrary, under the influence of the revolution, the concrete molding is made more uniform and dense, thereby improving the strength of the concrete pile. After the concrete pile is centrifuged and cured, the concrete pile is formed, the molding cylinder 6 is aligned with the tapered hole 22 again, and the mold in the molding cylinder 6 is hooked out. Since the other end of the block 65 is provided with a guide angle 651 in the axial direction of the molding cylinder 6, it will not affect the removal of the mold.

[0048] In Embodiment 4, the driven gear 61 is fixedly connected to the forming cylinder 6, and the driven gear 61 is rotationally sealedly connected to the steam pipe 33.
