Description

Technical Field

[0001] The present invention belongs to the technical field of pipe pile curing, and more specifically, relates to an automatic energy-saving curing device for PHC pipe piles. Background Art

[0002] PHC pipe piles are a kind of basic building materials, fully known as pre-tensioned high-strength concrete pipe piles, and are widely used in many fields such as industrial factories, large equipment foundations, urban elevated road foundations, highways, bridges, port terminals, airports, urban light rails, electric power, metallurgy, municipal engineering, civil buildings, and photovoltaics.

[0003] During the manufacturing process of PHC pipe piles, after the pipe piles are formed, steam curing is required. The steam curing of pipe piles is divided into normal-pressure steam curing and high-pressure steam curing. Normal-pressure steam curing uses a normal-pressure steam curing box, and high-pressure steam curing uses an autoclave.

[0004] Currently, during the steam curing process of PHC pipe piles, steam is generally input into the container from the pipeline near the inner wall of the container. In this way, it takes a certain period of time for the steam to enter the inside of the pipe pile well during steam curing, resulting in inconsistent steam curing conditions inside and outside the pipe pile. This not only causes differences in the curing effects inside and outside the pipe pile, but also increases the steam curing duration, causing waste of steam and energy. Summary of the Invention

Detailed description of the specific implementation

[0033] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] As Figure 1 shown, the present invention provides an automatic energy-saving curing device for PHC pipe piles, including:

[0035] A horizontal autoclave 1, one end of the horizontal autoclave 1 is provided with an opening, and a cover plate 2 capable of closing the opening is rotatably provided on one side of the opening;

[0036] A steam generating device 3, the steam generating device 3 is connected to the horizontal autoclave 1 through a first steam pipeline 4, a plurality of first steam outlets 5 are provided on the inner wall of the horizontal autoclave 1, and a plurality of second steam outlets 6 are provided on the inner side of the cover plate 2;

[0037] A conveying device, the conveying device can carry and convey a plurality of pipe piles 7 to be cured;

[0038] A plurality of second steam pipelines 8 are used to be inserted into the pile to be cured 7. A plurality of third steam outlets are arranged on the outer wall of the second steam pipeline 8. One end of the second steam pipeline 8 is detachably connected to the second steam outlet 6 through a connecting mechanism 9.

[0039] Specifically, to solve the problem that the steam curing conditions inside and outside the PHC pipe pile are inconsistent during the steam curing process in the prior art; the PHC pipe pile automatic energy-saving curing equipment provided by the present invention is respectively provided with a plurality of first steam outlets 5 and a plurality of second steam outlets 6 on the inner wall of the horizontal autoclave 1 and the inner side of the cover plate 2. The first steam outlet 5 and the second steam outlet 6 are connected to the steam generating device 3 through the first steam pipeline 4. The steam generated by the steam generating device 3 is input into the first steam outlet 5 and the second steam outlet 6 through the first steam pipeline 4, and then enters the horizontal autoclave 1. The steam entering through the first steam outlet 5 directly acts on the outside of the pile to be cured 7, and the steam entering through the second steam outlet 6 enters the second steam pipeline 8 through the connection of the connecting mechanism 9, and then directly acts on the inside of the pile to be cured 7, making the steam curing conditions inside and outside the pile to be cured 7 more consistent, not only reducing the curing effect difference between the inside and outside of the pile to be cured 7, but also being able to shorten the high-pressure steam curing time, saving steam and energy. At the same time, due to the setting of the horizontal autoclave 1 in cooperation with the conveying device and the connecting mechanism 9, the equipment can cure a plurality of piles to be cured 7 at one time, and there is no need for hoisting, which can improve the safety and operation convenience while realizing convenient automatic transmission and steam pipeline connection, and improve the automation degree and oxidation efficiency.

[0040] In this embodiment, the steam generating device 3 includes a boiler. The steam generated by the boiler is input into a plurality of first steam outlets 5 and a plurality of second steam outlets 6 through the first steam pipeline; during the specific transmission process, a first transmission network connected to a plurality of first steam outlets 5 can be arranged on one side of the side wall of the horizontal autoclave 1, and a second transmission network connected to a plurality of second steam outlets 6 can be arranged on one side of the cover plate 2. The first transmission network and the second transmission network are connected to the first steam pipeline 4 to realize the transmission and distribution of steam.

[0041] Optionally, the second steam pipeline 8 is in a straight tube shape, and a plurality of support rods 10 are radially arranged on the outer periphery of the second steam pipeline 8. The support rods 10 are spaced apart along the axial direction of the second steam pipeline.

[0042] Specifically, the second steam pipeline 8 adopts a straight pipe. The plurality of support rods 10 arranged on the outer periphery of the straight pipe can support the second steam pipeline 8 circumferentially when it is inserted into the pile to be cured 7, so that the second steam pipeline 8 is as close as possible to the axis of the pile to be cured 7. This not only facilitates the connection between the second steam pipeline 8 and the connecting mechanism 9, but also enables the distance between the second steam outlets 6 on the second steam pipeline 8 and the inner wall of the pile to be cured 7 to be more consistent, improving the steam curing effect.

[0043] Optionally, the support rod 10 is an elastic support rod 10, and the sum of the length of the support rod 10 and the radius of the second steam transmission pipeline 8 is greater than the inner peripheral radius of the pile to be cured 7.

[0044] Specifically, during the process of inserting the second steam transmission pipeline 8 into the pile to be cured 7, each support rod 10 undergoes a small amount of elastic deformation, and supports the second steam transmission pipeline 8 in the pile to be cured 7 more evenly from the radial direction, ensuring the centering degree of the second steam transmission pipeline 8.

[0045] Optionally, the connecting mechanism 9 includes:

[0046] A connecting pipe 11, one end of the connecting pipe 11 is connected to the inner side of the cover plate 2, an insertion slot 12 matching with the second steam transmission pipeline 8 is arranged on the inner side of the other end of the connecting pipe 11, and a flared structure 13 is arranged on the outer side of the other end of the connecting pipe 11;

[0047] A sealing gasket 14, and the sealing gasket 14 is arranged at the bottom of the insertion slot 12.

[0048] Specifically, as Figure 2 shown, the outer diameter of the connecting pipe 11 is greater than the outer diameter of the second steam transmission pipeline 8, their inner diameters are the same, and an annular insertion slot 12 is arranged on the inner circumference of the other end of the connecting pipe 11. The flared structure 13 on the outer circumference of the other end of the connecting pipe 11 provides guidance for the insertion of the second steam transmission pipeline 8 into the insertion slot 12, so that as long as the second steam transmission pipeline 8 is within the guiding range of the flared structure 13 under the support of the support rod 10, it can be automatically inserted into the insertion slot 12 when the cover plate 2 is closed, realizing the connection with the second steam outlet 6. The setting of the sealing gasket 14 ensures the sealing performance of the connection position.

[0049] Optionally, a locking groove 15 is arranged on the outer circumference of the end of the second steam transmission pipeline 8 close to the cover plate 2. At least two through slots are evenly arranged on the wall of the flared structure 13, and a locking hook 16 is arranged in each through slot. One end of the locking hook 16 is hook-shaped and cooperates with the locking groove 15. The middle of the locking hook 16 is rotatably connected to the wall of the through slot. The other end of the locking hook 16 is used for mechanical interference with the outer wall of the second steam transmission pipeline 8 and can make one end of the locking hook 16 enter the locking groove 15 when the second steam transmission pipeline 8 is inserted into the insertion slot 12.

[0050] Specifically, during the process of inserting the second steam transmission pipeline 8 into the insertion slot 12, it contacts and pushes the other end of the locking hook 16 outward, causing it to rotate, and then making one end of the locking hook 16 enter the locking groove 15 and hook the groove wall of the locking groove 15 close to the cover plate 2 side, locking the second steam transmission pipeline 8 inserted into the connecting pipe 11 and improving the sealing performance.

[0051] Optionally, the other end of the locking hook 16 is provided with an arc surface and contacts the second steam delivery pipeline 8 through the arc surface. The locking hook 16 is rotatably connected to the groove wall of the through groove through a rotating shaft, and one end of the rotating shaft is sleeved with a torsion spring. The torsion spring is used to apply a torque to the locking hook 16 so that the locking hook 16 rotates and one end of the locking hook 16 expands outwards.

[0052] Specifically, the setting of the torsion spring makes the locking hook 16 have a tendency to rotate, and its hook-shaped end naturally expands outwards. As the cover plate 2 is opened and the connecting pipe 11 moves outwards, in cooperation with the arc surface, the torsion spring drives the locking hook 16 to rotate, automatically releasing the locking of the second steam delivery pipeline 8 and enabling it to smoothly withdraw from the insertion slot 12.

[0053] Optionally, the conveying device includes:

[0054] A fixed support plate 17, which is arranged in the horizontal autoclave 1;

[0055] A movable support plate 18, which is movably arranged outside one end of the horizontal autoclave 1;

[0056] A transfer cart 19, which is used to move on the movable support plate 18 and the fixed support plate 17. A support platform is arranged on the upper side of the transfer cart 19, and the support platform is used to carry a plurality of pipe piles 7 to be cured.

[0057] Specifically, since the opening of the horizontal autoclave 1 is arranged at one end thereof and the axis of the horizontal autoclave 1 is horizontally arranged, a plurality of pipe piles 7 to be cured enter the horizontal autoclave 1 horizontally; to facilitate the transmission of a plurality of pipe piles 7 in the horizontal autoclave 1 and improve the automation degree of the curing operation, the conveying device is provided with a fixed support plate 17 and a movable support plate 18 inside and outside the horizontal autoclave 1 respectively. The upper surfaces of the fixed support plate 17 and the movable support plate 18 are at the same height. After the cover plate 2 is opened, the movable support plate 18 moves to the end of the fixed support plate 17 and is connected to it to form an integral platform for the transfer cart 19 to move, facilitating the transfer cart 19 to enter the horizontal autoclave 1; the support platform on the transfer cart 19 carries a plurality of pipe piles 7 to be cured, realizing the convenient transmission of the pipe piles 7 to be cured.

[0058] Optionally, the horizontal autoclave 1 is cylindrical. Above the support platform, at least one set of first limiting rods 20 and one set of second limiting rods 22 are arranged in sequence. On the upper side of each set of the first limiting rods 20, a layer of pipe piles 7 to be cured is arranged. On the upper side of each set of the second limiting rods 22, a layer of pipe piles 7 to be cured is arranged. At both ends of the first limiting rod 20, first convex portions 21 are respectively arranged. Between the two first convex portions 21, a first number of pipe piles 7 to be cured that can be accommodated and placed side by side can be placed. At both ends of the second limiting rod 22, second convex portions 23 are respectively arranged. Between the two second convex portions 23, a second number of pipe piles 7 to be cured that can be accommodated and placed side by side can be placed. The second number is less than the first number.

[0059] Specifically, the horizontal autoclave 1 is cylindrical. In order to load more pipe piles 7 to be cured at one time and make the distances between the pipe piles 7 to be cured at various positions inside the horizontal autoclave 1 and the inner wall of the horizontal autoclave 1 similar, at least one set of first limiting rods 20 and one set of second limiting rods 22 are arranged above the support platform. The number of each set of the first limiting rods 20 and each set of the second limiting rods 22 is determined according to the length of the pipe piles 7 to be cured, so that multiple pipe piles 7 to be cured on the support platform are placed in layers, and the number of pipe piles 7 to be cured placed inside is more at the middle position of the horizontal autoclave 1 and less at the upper position of the horizontal autoclave 1, and the horizontal autoclave 1 is filled as much as possible.

[0060] In this embodiment, as Figure 3 shown, two sets of first limiting rods 20 are arranged, and one set of second limiting rods 22 is arranged.

[0061] In this embodiment, third convex portions 24 are further arranged below the first limiting rods 20 and the second limiting rods 22. The third convex portions 24 are used for limiting cooperation with the transfer vehicle 19 or the pipe piles 7 to be cured below them.

[0062] Optionally, the horizontal autoclave 1 is connected with an exhaust pipe 25, and the exhaust pipe 25 is connected with the atmospheric steam curing box 27.

[0063] Specifically, when the high-pressure steam curing ends, the horizontal autoclave 1 is depressurized, and a large amount of high-temperature steam will be discharged, resulting in waste of steam and high temperature. By connecting the horizontal autoclave 1 with the atmospheric steam curing box 27 through the exhaust pipe 25 and controlling the on-off valve on the exhaust pipe 25, the high temperature inside the horizontal autoclave 1 can be integrally discharged into the atmospheric steam curing box 27 for the atmospheric steam curing of the next batch of pipe piles 7 to be cured, further saving steam and energy.

[0064] Optionally, casters 26 are arranged on the lower side of the movable support plate 18.

[0065] Specifically, the movable support plate 18 is conveniently moved through the setting of the casters 26. After the high-pressure steam curing is completed, the cover plate 2 is opened, and then the movable support plate 18 is pulled to move the movable support plate 18 to the docking position with the fixed support plate 17. Then, the cured pipe piles are removed from the horizontal autoclave 1 by the transporter 19.

[0066] The embodiments of the present invention have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
