Description

Technical Field

[0001] This utility model belongs to the field of concrete pipe pile production technology, specifically relating to a mold clamping and fixing device for producing concrete pipe piles. Background Technology

[0002] Concrete pipe piles are a type of pile foundation structure made primarily of concrete and having a tubular shape. They are commonly used in the foundation construction of buildings, bridges, and other engineering projects. They can withstand vertical loads and lateral forces and are widely used in soft soil foundations or other unstable soil layers. In the production process of concrete pipe piles, a circular mold is usually used to pour concrete. A mold fixing device is used to ensure the stability of the mold and prevent it from deforming or moving during the pouring process.

[0003] Chinese patent discloses a mold-closing device for the production of prestressed concrete pipe piles (authorization announcement number CN222681284U). This patented technology, through the setting of a sliding mechanism, allows the fixed blocks to be loosened after the concrete pipe pile is formed, so that the mold bodies on both sides separate. Subsequently, the mold bodies are pulled outward. The mold bodies can reduce the friction between the first and second sliding blocks and the base through the ball bearings at the bottom of the first and second sliding blocks, making the mold bodies easier to move and less strenuous to move. This realizes that the device has the function of facilitating the movement and separation of the mold bodies, and improves the convenience of the mold-closing device for the production of prestressed concrete pipe piles during use.

[0004] However, most existing concrete pipe pile molds are installed as a single unit, making them unchangeable and unable to meet the production needs of different pipe piles, resulting in low practicality. For example, the aforementioned comparative document uses a single-unit mold installation method. In practical applications, since different types of concrete pipe piles need to be produced, the inability to change the mold hinders production. Therefore, those skilled in the art provide a mold-closing and fixing device for producing concrete pipe piles to solve the problems mentioned in the background art. Summary of the Invention

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4As shown, a mold-closing and fixing device for producing concrete pipe piles includes a base plate 1, a connecting plate 11 disposed on the upper end face of the base plate 1, and a top plate 12 disposed on the upper end of the connecting plate 11. Columns 21 are symmetrically arranged on the upper surface of the base plate 1. A first mounting plate 2 is connected to the upper end of the column 21. A first mold 4 is slidably mounted on the upper surface of the first mounting plate 2. A lifting cylinder 6 is mounted on the upper surface of the top plate 12. A second mounting plate 3 is disposed at the lower end of the lifting cylinder 6. A second mold 5 is slidably mounted on the lower surface of the second mounting plate 3. Guide rods 61 are symmetrically arranged on the upper surface of the second mounting plate 3. A second positioning plate 51 is disposed on the upper surface of the second mold 5. A first positioning plate 41 is mounted on the lower surface of the first mold 4. This device utilizes the slidably mounted first mold 4 and second mold 5 to achieve installation, disassembly, and replacement, thus meeting the production needs of different concrete pipe piles. Simultaneously, the lifting cylinder 6 can be used to raise and lower the second mounting plate 3 to achieve automatic mold closure.

[0025] like Figure 2 As shown, the upper surface of the first mounting plate 2 is provided with a first mounting groove 22, and the first positioning plate 41 is T-shaped and is slidably installed inside the first mounting groove 22. This arrangement allows the first positioning plate 41 to slide inside the first mounting groove 22, thus achieving the purpose of quick installation and disassembly of the first mold 4.

[0026] like Figure 3 and Figure 4 As shown, a second mounting groove 32 is provided on the lower surface of the second mounting plate 3, and the second positioning plate 51 is T-shaped and is slidably installed inside the second mounting groove 32. This arrangement allows the second positioning plate 51 to slide inside the second mounting groove 32, which facilitates the installation, disassembly and replacement of the second mold 5.

[0027] like Figure 1 As shown in the figure, bolts are provided on the outside of the second mounting plate 3 and the first mounting plate 2. Positioning holes 52 are provided on the outer surfaces of the first positioning plate 41 and the second positioning plate 51. The ends of the bolts are inserted into the positioning holes 52 and threadedly connected to the positioning holes 52. This arrangement utilizes the threaded connection between the bolts and the positioning holes 52 to position and install the first positioning plate 41 and the second positioning plate 51 into the inside of the first mounting groove 22 and the second mounting groove 32, so as to facilitate the subsequent production of concrete pipe piles.

[0028] like Figure 1 As shown, both the second mold 5 and the first mold 4 are semi-cylindrical, and the lower surface of the second mold 5 is in contact with the upper surface of the first mold 4. This arrangement allows for rapid mold closing by utilizing the contact between the first mold 4 and the second mold 5, thereby completing the production of concrete pipe piles.

[0029] like Figure 3As shown, two guide rods 61 are symmetrically arranged on the upper surface of the second mounting plate 3, and the upper end of the guide rod 61 penetrates the upper surface of the top plate 12. This arrangement can guide the second mounting plate 3 when it is raised and lowered, thus ensuring the stability of the mold closing.

[0030] like Figure 3 As shown, a connecting sleeve 31 is also installed on the upper surface of the second mounting plate 3. The fixed end of the lifting cylinder 6 is installed on the upper surface of the top plate 12, and the telescopic end of the lifting cylinder 6 is embedded in the connecting sleeve 31 and connected by bolts. This setting uses bolts to connect the telescopic end of the lifting cylinder 6. After connection, when the lifting cylinder 6 works, the second mounting plate 3 is raised and lowered. In this way, the second mold 5 can be moved to the position of the first mold 4 to achieve the purpose of mold closing.

[0031] The working principle of this utility model is as follows: When using the mold-closing and fixing device for producing concrete pipe piles, the first mold 4 and the second mold 5 are first installed. During installation, the first mold 4 is installed by sliding the first positioning plate 41 on its lower surface inside the first mounting groove 22. At the same time, the second positioning plate 51 on the upper surface of the second mold 5 is slid into the second mounting groove 32 and locked with bolts after installation. This allows the first mold 4 and the second mold 5 to be installed and used. After installation, the operation of the lifting cylinder 6 will cause the second mounting plate 3 to rise and fall. During the rising and falling, the guide rod 61 will guide the second mold 5 to move towards the position of the first mold 4, achieving the purpose of automatic mold closure. After mold closure, the mortar for producing concrete pipe piles can enter the interior of the second mold 5 through the feed port (not shown in the figure) on the outside of the second mold 5 to produce concrete. The first mold 4 and the second mold 5 can be quickly installed, disassembled and replaced, thereby meeting the needs of mold-closing production of different concrete pipe piles. The second mold 5 automatically moves towards the position of the first mold 4, achieving the purpose of automatic mold closure, which is very practical.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
