Description

Technical Field

[0001] This utility model relates to the field of square pile maintenance technology, and in particular to a temperature control device for steam curing of square piles. Background Technology

[0002] In the production process of precast concrete square piles, steam curing is a key process that determines the mechanical properties of the piles. By controlling the temperature curves of the three stages of heating, constant temperature, and cooling, the hydration reaction of concrete can be accelerated, thereby improving the early strength and durability of the piles.

[0003] Traditional steam curing devices for square piles often use fixed nozzles or static steam pipes, making it difficult for steam to cover the entire surface of the square pile. In particular, blind spots are easily formed at the edges and bottom of the square pile, resulting in surface temperature differences and causing problems such as concrete cracking and high strength dispersion. At the same time, square piles are mostly static during the curing process, with a single heating surface continuously heated, making it difficult to achieve uniform heat exchange in all directions. This makes the non-uniformity of the temperature field increasingly significant. Therefore, it is necessary to propose a temperature control device for steam curing of square piles to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a steam curing temperature control device for square piles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A temperature control device for steam curing of square piles includes a frame with open upper ends. Two sets of rotating rollers are symmetrically arranged inside the frame. Each set of rotating rollers has multiple sets of rubber pads arranged along its axial direction on its outer wall. A side plate is fixedly connected to the upper end of the frame, and a side plate frame is fixedly connected to the lower end of the side plate. The side plate frame is arranged along the axial direction of the rotating rollers. A lead screw sleeve is movably connected inside the side plate frame. A steam spray plate is fixedly connected to the lower end of the lead screw sleeve. A steam pipe is arranged on the outer wall of the steam spray plate. A drive mechanism for driving the lead screw sleeve is installed inside the frame.

[0006] Preferably, the drive mechanism includes a reciprocating screw rotatably connected within the side plate frame, and the screw is threadedly connected to the threaded section of the reciprocating screw.

[0007] Preferably, two sets of limiting rods are fixedly connected to the inner wall of the side plate frame, and the lead screw sleeve is slidably connected to the outer wall of the two sets of limiting rods.

[0008] Preferably, the frame sidewall is rotatably connected to two sets of transmission wheels, the two sets of transmission wheels are interconnected by a transmission belt, and the two sets of transmission wheels are respectively coaxially and fixedly connected to two sets of rotating rollers.

[0009] Preferably, a second transmission wheel is coaxially fixedly connected to the outer wall of the first transmission wheel, and a third transmission wheel is rotatably connected to the outer wall of the side plate frame. The third transmission wheel is coaxially fixedly connected to the reciprocating screw, and the radius of the second transmission wheel is larger than that of the third transmission wheel. The second transmission wheel is connected to the third transmission wheel via a second transmission belt.

[0010] Preferably, a servo motor is fixedly connected to the side wall of the frame, and the output shaft of the servo motor is coaxially fixedly connected to its adjacent rotating roller.

[0011] This utility model has the following beneficial effects: 1. This utility model uses rubber pads on the outer walls of two sets of rotating rollers to contact the square pile, enabling the square pile to rotate continuously 360° under the drive of a servo motor. At the same time, the steam spray plate moves back and forth along the axis of the rotating rollers with the reciprocating screw. The two work together to enable the steam to dynamically cover the entire surface of the square pile, effectively solving the problem of spray blind spots formed by traditional fixed nozzles at the corners and bottom of the square pile. This allows all parts of the square pile to receive steam spray evenly, avoiding uneven temperature field caused by continuous heating of a single heating surface.

[0012] 2. This utility model utilizes the radius difference between transmission wheel two and transmission wheel three to create a speed difference. By using a single servo motor power source to simultaneously drive the rotating roller to rotate and the steam spray plate to reciprocate, it achieves power coordination between the rotating mechanism and the spraying mechanism, ensuring stable coordination between the rotation of the square pile and the steam spraying, and improving the reliability and efficiency of the steam curing process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-3 A steam curing temperature control device for square piles includes a frame 1, with the upper end face of the frame 1 being open. Two sets of rotating rollers 2 are symmetrically arranged inside the frame 1. Each set of rotating rollers 2 has multiple sets of rubber pads arranged along its axial direction on its outer wall. A side plate 8 is fixedly connected to the upper end of the frame 1, and a side plate frame 9 is fixedly connected to the lower end of the side plate 8. The side plate frame 9 is arranged along the axial direction of the rotating rollers 2. A screw sleeve 14 is movably connected inside the side plate frame 9. A steam spray plate 13 is fixedly connected to the lower end of the screw sleeve 14. A steam pipe 15 is arranged on the outer wall of the steam spray plate 13. A drive mechanism for driving the screw sleeve 14 to move is installed inside the side plate frame 9. Furthermore, the two sets of symmetrically arranged rotating rollers 2, together with the outer wall rubber pads, can stably drive the square pile to rotate through friction, avoiding the problem of the square pile being continuously heated on a static single heating surface in traditional devices. This allows the square pile to achieve all-round heat exchange during the curing process. The steam spray plate 13 moves along the axis of the rotating rollers 2 with the drive mechanism, which can dynamically cover the entire surface of the square pile, effectively solving the spray blind zone formed by the traditional fixed nozzles at the corners and bottom of the square pile, and improving the uniformity of steam distribution.

[0018] The drive mechanism includes a reciprocating screw 11 rotatably connected in the side plate frame 9, a screw sleeve 14 threadedly connected to the threaded section of the reciprocating screw 11, and two sets of limiting rods 12 fixedly connected to the inner wall of the side plate frame 9. The screw sleeve 14 is slidably connected to the outer wall of the two sets of limiting rods 12. Furthermore, the threaded transmission structure of the reciprocating screw 11 and screw sleeve 14 can convert the rotational motion into the linear reciprocating motion of the steam spray plate 13, ensuring that the steam evenly covers all parts of the square pile and avoiding local overheating or underheating problems caused by spray position deviation.

[0019] Two sets of transmission wheels 3 are rotatably connected to the side wall of frame 1. The two sets of transmission wheels 3 are connected to each other through transmission belt 4. The two sets of transmission wheels 3 are respectively fixedly connected to two sets of rotating rollers 2 on the same axis. Furthermore, the two sets of transmission wheels 3 connected by the transmission belt 4 can achieve synchronous rotation of the two sets of rotating rollers 2, ensuring that the square pile rotates stably between the two sets of rotating rollers 2, and avoiding the inconsistent speed or slippage that may occur with traditional independently driven rotating rollers.

[0020] One set of transmission wheels 1 3 is coaxially fixedly connected to the outer wall of transmission wheel 2 5, and the outer wall of the side plate frame 9 is rotatably connected to transmission wheel 3 7. Transmission wheel 3 7 is coaxially fixedly connected to the reciprocating screw 11, and the radius of transmission wheel 2 5 is larger than the radius of transmission wheel 3 7. Transmission wheel 2 5 is connected to transmission wheel 3 7 through transmission belt 2 6. Furthermore, by utilizing the radius difference between transmission wheel 2 5 and transmission wheel 3 7 to form a speed difference, the servo motor 10 drives the square pile to rotate and the steam spray plate 13 to reciprocate simultaneously through a set of rotating rollers 2, thereby achieving power coordination between the rotating mechanism and the spraying mechanism.

[0021] A servo motor 10 is fixedly connected to the side wall of frame 1, and the output shaft of the servo motor 10 is coaxially fixedly connected to its adjacent rotating roller 2.

[0022] In this utility model, when the device is used, the square pile to be cured is first placed horizontally between the two sets of rotating rollers 2 in the frame 1. The two ends of the square pile are in contact with the rubber pads on the outer wall of the two sets of rotating rollers 2 respectively. The rubber pads increase the friction to ensure that the square pile and the rotating rollers 2 move synchronously.

[0023] The operator then starts the servo motor 10, whose output shaft drives the adjacent rotating roller 2 to rotate clockwise. This rotating roller 2, through a coaxially fixed transmission wheel 3 and transmission belt 4, drives another set of transmission wheels 3 to rotate synchronously, so that the two sets of rotating rollers 2 rotate at the same speed. The square pile rotates under the friction of the rubber pads of the rotating roller 2, achieving continuous 360° rotation, avoiding the problem of the square pile being continuously heated on a single stationary heating surface in traditional devices, and ensuring that different areas of its surface can be alternately sprayed with steam.

[0024] Meanwhile, transmission wheel 2 5, coaxially fixed with one of the transmission wheels 3, rotates synchronously with the rotating roller 2, driving transmission wheel 3 7 on the outer wall of the side plate frame 9 to rotate via transmission belt 2 6. Since the radius of transmission wheel 2 5 is larger than that of transmission wheel 3 7, a speed difference is created, causing the reciprocating screw 11, coaxially fixed with transmission wheel 3 7, to rotate at a higher speed. The threaded section of the reciprocating screw 11 drives the screw sleeve 14 to reciprocate along the axial direction of the rotating roller 2, and the screw sleeve 14 synchronously drives the steam spray plate 13 to perform linear reciprocating motion within the side plate frame 9. During this process, two sets of limiting rods 12 on the inner wall of the side plate frame 9 guide and limit the screw sleeve 14, preventing it from shifting or wobbling during movement, ensuring that the steam spray plate 13 slides smoothly back and forth along the axial direction of the rotating roller 2. When the steam pipe 15 is connected to the steam source, the steam spray plate 13 continuously sprays steam during its movement. Its reciprocating motion trajectory covers the entire length of the square pile. Combined with the rotation of the square pile itself, the steam can dynamically and evenly act on areas that are difficult to cover by traditional fixed nozzles, such as the edges and bottom of the square pile, effectively eliminating spray blind spots. This avoids the problem of local overheating or underheating caused by spray position deviation, making the temperature field distribution on the surface of the square pile more uniform.

[0025] In summary, this device simultaneously drives the square pile to rotate and the steam spray plate 13 to reciprocate using a single power source. It utilizes the radius difference between transmission wheel 2 5 and transmission wheel 3 7 to achieve power coordination between the rotating mechanism and the spraying mechanism. This eliminates the need for multiple independent power systems found in traditional devices, simplifying the equipment structure and reducing the risk of asynchronous transmission. Throughout the curing process, the square pile continuously rotates under the drive of the rotating roller 2, while the steam spray plate 13 reciprocates synchronously. The synergistic effect of these two mechanisms achieves dynamic coverage and uniform heat exchange of the entire surface of the square pile with steam, improving the quality and efficiency of steam curing and effectively solving problems such as uneven temperature distribution and high energy consumption found in traditional devices.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
