Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe pile curing, and particularly to a steam curing device for the production of energy-saving and environment-friendly prestressed concrete pipe piles. Background Art

[0002] In the field of construction engineering, prestressed concrete pipe piles are widely used in various foundation engineering projects due to their advantages such as high strength and high durability. Steam curing, as a key process link in the production of pipe piles, plays a decisive role in the strength and quality of pipe piles.

[0003] Traditional curing devices lack a dynamic adjustment mechanism in the pipe pile stacking link. Workers need to manually adjust the spacing between pipe piles, resulting in low efficiency and poor uniformity of the spacing. When pipe piles are densely stacked, the steam circulation is blocked, easily leading to uneven local temperature and affecting the curing quality. If the spacing is too large, the space of the steam curing kettle is wasted, reducing the single curing output. This defect in interval control not only prolongs the curing time but also may lead to a decrease in the turnover efficiency of pipe piles due to an increase in the rework rate, further lengthening the entire process cycle from production to transportation. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a steam curing device for the production of energy-saving and environment-friendly prestressed concrete pipe piles.

[0005] The technical solution adopted by the present invention to solve its technical problems is a steam curing device for the production of energy-saving and environment-friendly prestressed concrete pipe piles, including a steam curing kettle with an inner track in the kettle, and a moving vehicle moving along the direction of the inner track in the kettle. A number of groups of bottom brackets are installed on the upper part of the moving vehicle, and an arc-shaped plate member whose axis is parallel to the axis of the steam curing kettle is slidably connected to the bottom of the moving vehicle.

[0007] Specifically, the bottom brackets are connected to the moving vehicle through spring rods, and racks penetrating the moving vehicle are connected to the lower parts of the bottom brackets. The racks are in transmission with the driving rod through a transmission assembly.

[0008] Specifically, positioning tubes are connected to one ends of the first arc-shaped plates and the second arc-shaped plates close to the upper bracket. A positioning groove in sealed sliding connection with the positioning tubes is provided on the lower surface of the upper bracket. A positioning column is connected in the positioning groove, and a slider slidably connected to a spiral guiding groove provided on the inner wall of the positioning tube is connected to the lower end of the positioning column.

[0009] Specifically, a limiting plate is provided at one end of the first arc-shaped plate and the second arc-shaped plate away from the upper bracket.

[0010] Specifically, movable grooves are opened at one end of the first arc-shaped plate and the second arc-shaped plate close to the limiting plate. A sliding column fixedly connected to the limiting plate is hermetically and slidably connected in the movable groove. A return spring is connected between the sliding column and the movable groove; through grooves communicating the movable groove with the positioning pipe are provided in both the first arc-shaped plate and the second arc-shaped plate.

[0013] Specifically, the transmission assembly includes a transmission shaft arranged at the bottom of the mobile vehicle, a transmission belt pulley installed on the transmission shaft, and a driven belt pulley installed on the driving rod. A belt drive is provided between the transmission belt pulley and the driven belt pulley.

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] As an embodiment of the present invention, as Figures 1-6 shown, a steam curing device for the production of energy-saving and environment-friendly prestressed concrete pipe piles according to the present invention includes a steam curing kettle 1 having an inner kettle track 2, and a moving cart 3 moving along the direction of the inner kettle track 2. A plurality of groups of bottom brackets 4 are installed on the upper part of the moving cart 3. The bottom of the moving cart 3 is slidably connected with an arc-shaped plate member 5 whose axis is parallel to the axis of the steam curing kettle 1. One end of the arc-shaped plate member 5 is rotatably connected with an upper bracket 6.

[0027] During use, after placing the pipe pile on the bottom bracket 4, the arc-shaped plate member 5 can be driven to swing, so as to place the upper bracket 6 on the pipe pile on the bottom bracket 4, thereby facilitating the subsequent stacking of the pipe piles, improving the convenience of pipe pile stacking, reducing labor consumption and saving resources. It should be noted that in order to facilitate the moving cart 3 to move the pipe pile, a docking track 7 is provided on one side of the opening of the steam curing kettle 1. The bottom of the docking track 7 can be supported by a hydraulic lifting device 8 to realize the lifting adjustment of the docking track 7. An outer kettle track 9 can also be provided on one side of the docking track 7 to facilitate the movement of the moving cart 3.

[0028] In order to facilitate the driving of the arc-shaped plate member 5 to move along the arc direction, as an embodiment of the present invention, the arc-shaped plate member 5 includes a plurality of groups of first arc-shaped plates 501 and second arc-shaped plates 502. A driving rod 10 is provided at the bottom of the moving vehicle 3, and friction wheels 11 respectively in frictional transmission with the first arc-shaped plate 501 and the second arc-shaped plate 502 are installed on the driving rod 10. A plurality of groups of auxiliary rollers 12 for rolling and supporting the first arc-shaped plate 501 and the second arc-shaped plate 502 are provided at the bottom of the moving vehicle 3.

[0029] During use, the rotation of the driving rod 10 can drive the friction wheels 11 to rotate. Thus, through the frictional transmission between the friction wheels 11 and the first arc-shaped plate 501 and the second arc-shaped plate 502, it is convenient to drive the first arc-shaped plate 501 and the second arc-shaped plate 502 to move, so as to lift the upper bracket 6 to a specific height to meet the stacking work of the upper layer of pipe piles; the stability of the movement of the first arc-shaped plate 501 and the second arc-shaped plate 502 can be ensured through the auxiliary rollers 12. It should be noted that the arc length of the second arc-shaped plate 502 is greater than that of the first arc-shaped plate 501. And it should be noted that the arc-shaped plate member 5 of the present invention can be multiple groups of arc-shaped plates with gradually increasing arc lengths, so as to conveniently support the upper brackets 6 at different heights, thus facilitating the subsequent stacking of pipe piles.

[0030] In order to facilitate the automatic operation of the driving rod 10 during the stacking of pipe piles, as an embodiment of the present invention, the bottom bracket 4 is connected to the moving vehicle 3 through a spring rod 13. A rack 14 penetrating the moving vehicle 3 is connected to the lower part of the bottom bracket 4, and the rack 14 is in transmission with the driving rod 10 through a transmission assembly.

[0031] During use, when the pipe pile is stacked on the bottom bracket 4, it can drive the bottom bracket 4 to sink automatically. At this time, the spring rod 13 is compressed and the rack 14 moves downward; when the rack 14 moves downward, it drives the driving rod 10 to rotate through the transmission assembly, thereby driving the friction wheels 11 to rotate, pushing the first arc-shaped plate 501 and the second arc-shaped plate 502 upward, so as to lift the upper bracket 6 to the designated height to meet the requirements of subsequent pipe pile stacking;

[0032] At the same time, when the pipe pile on the bottom bracket 4 is unloaded, the bottom bracket 4 automatically rises due to the rebound of the spring rod 13, thereby driving the rack 14 to move upward, driving the driving rod 10 to reverse, and driving the first arc-shaped plate 501 and the second arc-shaped plate 502 to swing downward through the friction wheels 11, putting down the upper bracket 6 to avoid affecting the subsequent pipe pile stacking work.

[0033] To facilitate the downward movement of the upper bracket 6 after rotation to automatically fit the pile pipes stacked below, as an embodiment of the present invention, positioning pipes 15 are connected to one ends of the first arc-shaped plate 501 and the second arc-shaped plate 502 close to the upper bracket 6. A positioning groove 16 for sealing and sliding connection with the positioning pipe 15 is provided on the lower surface of the upper bracket 6. A positioning post 17 is connected in the positioning groove 16. A slider 18 that is slidably connected to a spiral guiding groove provided on the inner wall of the positioning pipe 15 is connected to the lower end of the positioning post 17.

[0034] During use, when the positioning pipe 15 moves along the positioning groove 16, it can drive the slider 18 on the positioning post 17 to move along the spiral guiding groove, thereby driving the upper bracket 6 to swing automatically, and the upper bracket 6 will swing by ninety degrees and thus be perpendicular to the pile pipes; thereby realizing the downward movement of the upper bracket 6 during the swinging process, so that the upper bracket 6 and the pile pipes stacked below are in contact, thereby facilitating the subsequent stacking of pile pipes on the upper bracket 6.

[0035] To prevent the first arc-shaped plate 501 and the second arc-shaped plate 502 from disengaging from the friction wheel 11, as an embodiment of the present invention, limit plates 19 are provided at one ends of the first arc-shaped plate 501 and the second arc-shaped plate 502 far from the upper bracket 6.

[0036] During use, as the friction wheel 11 drives the first arc-shaped plate 501 and the second arc-shaped plate 502 to swing, the auxiliary roller 12 contacts the limit plate 19. At this time, the movement of the first arc-shaped plate 501 and the second arc-shaped plate 502 is blocked, and relative sliding occurs between the first arc-shaped plate 501, the second arc-shaped plate 502 and the friction wheel 11.

[0037] To facilitate driving the upper bracket 6 to swing automatically, as an embodiment of the present invention, movable grooves 20 are provided at one ends of the first arc-shaped plate 501 and the second arc-shaped plate 502 close to the limit plate 19. A sliding post 21 fixedly connected to the limit plate 19 is sealingly and slidably connected in the movable groove 20; a return spring is connected between the sliding post 21 and the movable groove 20. Through grooves for communicating the movable groove 20 with the positioning pipe 15 are provided in both the first arc-shaped plate 501 and the second arc-shaped plate 502.

[0038] During use, as the friction wheel 11 drives the first arc plate 501 and the second arc plate 502 to swing, the auxiliary roller 12 contacts the limit plate 19. Then, as the friction wheel 11 continues to drive the first arc plate 501 and the second arc plate 502 to move, the limit plate 19 pulls the sliding column 21 out of the movable slot 20. At this time, a negative pressure is formed in the movable slot 20, thereby driving a negative pressure to be formed in the positioning slot 16, so as to drive the positioning tube 15 to move in the positioning slot 16. When the positioning tube 15 moves along the positioning slot 16, it can drive the slider 18 on the positioning column 17 to move along the spiral guiding slot, thereby driving the upper bracket 6 to swing automatically, and the upper bracket 6 will swing by ninety degrees, so as to be perpendicular to the pipe pile. Thus, the upper bracket 6 moves downward during the swinging process, so that the upper bracket 6 abuts against the pipe piles stacked below, thereby facilitating the subsequent stacking of pipe piles on the upper bracket 6.

[0039] Moreover, after the steam heating and curing in the autoclave 1, the gas in the positioning tube 15, the through slot, and the movable slot 20 expands due to heat, resulting in an increase in air pressure, and the upper bracket 6 is squeezed upward. Once the pipe piles on the upper bracket 6 are unloaded, the upper bracket 6 will automatically lift without being obstructed by the pipe piles, and the slider 18 moves along the spiral guiding slot, thereby driving the upper bracket 6 to swing back to its original position to facilitate the subsequent loading and unloading of the pipe piles below this group of upper brackets 6.

[0040] To ensure the stability of the support roller 23 and the auxiliary roller 12, as an embodiment of the present invention, several groups of support seats 22 are installed at the bottom of the moving vehicle 3, the support roller 23 is installed on the side of the support seat 22, the driving rod 10 passes through the support seat 22 and is rotatably connected to the support seat 22, and the auxiliary roller 12 is rotatably connected to the support seat 22.

[0041] It should be noted that at least two groups of auxiliary rollers 12 are rotatably connected to the side of each support seat 22.

[0042] To facilitate the support of the pipe piles by the bottom bracket 4 and the upper bracket 6, arc-shaped grooves 24 that match the shape of the pipe piles are provided on the upper part of the bottom bracket 4 and on both the upper and lower sides of the upper bracket 6.

[0043] To ensure the transmission effect of the transmission assembly, as an embodiment of the present invention, the transmission assembly includes a transmission shaft 25 provided at the bottom of the moving vehicle 3, a transmission belt pulley 26 installed on the transmission shaft 25, and a driven belt pulley 27 installed on the driving rod 10. There is a belt drive between the transmission belt pulley 26 and the driven belt pulley 27, and both ends of the transmission shaft 25 are rotatably connected to a support plate 28 fixedly connected to the bottom of the moving vehicle 3.

[0044] When the present invention is in use, first, ensure that the autoclave 1 is in an open state, and then move the moving vehicle 3 to the outer track 9 through the inner track 2, the docking track 7; then hoist the pipe piles onto the bottom bracket 4 of the moving vehicle 3 through a hoisting device.

[0045] When the pipe piles are stacked on the bottom bracket 4, it can drive the bottom bracket 4 to sink automatically. At this time, the spring rod 13 is compressed and the rack 14 moves downward; when the rack 14 moves downward, it drives the drive rod 10 to rotate through the transmission component, thereby driving the friction wheel 11 to rotate, pushing the first arc plate 501 and the second arc plate 502 upward, so as to lift the upper bracket 6 to the specified height to meet the requirements of subsequent pipe pile stacking;

[0046] When the last pipe pile is stacked on the bottom bracket 4, the limiting plate 19 of the first arc plate 501 contacts the auxiliary roller 12; as the friction wheel 11 continues to drive the first arc plate 501 and the second arc plate 502 to move, the limiting plate 19 of the first arc plate 501 pulls the sliding column 21 out of the movable groove 20 of the first arc plate 501. At this time, a negative pressure is formed in the movable groove 20 of the first arc plate 501, thereby driving a negative pressure to be formed in the corresponding positioning groove 16 of the first arc plate 501, so as to drive the positioning pipe 15 of the first arc plate 501 to move in the positioning groove 16; when the positioning pipe 15 of the first arc plate 501 moves along the positioning groove 16, it can drive the slider 18 on the positioning column 17 to move along the spiral guide groove, thereby driving the upper bracket 6 to swing automatically, and the upper bracket 6 will swing 90 degrees, so as to be perpendicular to the pipe pile; thus, the upper bracket 6 moves downward during the swinging process, so that the upper bracket 6 is in contact with the pipe piles stacked below, thereby facilitating the subsequent stacking of the second layer of pipe piles on the upper bracket 6 above the bottom bracket 4;

[0047] After the second layer of pipe piles is stacked, the limiting plate 19 of the second arc plate 502 contacts the auxiliary roller 12; as the friction wheel 11 continues to drive the second arc plate 502 to move, the limiting plate 19 of the second arc plate 502 pulls the sliding column 21 out of the movable groove 20 of the second arc plate 502. At this time, a negative pressure is formed in the movable groove 20 of the second arc plate 502, thereby driving a negative pressure to be formed in the corresponding positioning groove 16 of the second arc plate 502, so as to drive the positioning pipe 15 of the second arc plate 502 to move in the positioning groove 16; when the positioning pipe 15 of the second arc plate 502 moves along the positioning groove 16, it can drive the slider 18 on the positioning column 17 to move along the spiral guide groove, thereby driving the upper bracket 6 to swing and move downward automatically, so as to facilitate the subsequent stacking of the third layer of pipe piles.
