Description

Technical Field

[0001] This application relates to the field of water conservancy and hydropower engineering technology, specifically to a plastic filler molding device with adjustable pitch angle. Background Technology

[0002] Concrete-faced rockfill dams are widely used both domestically and internationally due to their advantages such as low investment, convenient construction, and adaptability to local conditions. As the main seepage-proof structure, the concrete face has numerous structural joints on its surface to accommodate dam deformation. Seepage prevention is achieved through surface joint sealing. Typically, this involves filling pre-reserved V-grooves with plastic filler, and then protecting the filler with a cover plate or a coated polyurea layer. However, some of the plastic filler bulges used for surface joint sealing in concrete faces often have different sizes. Existing plastic filler forming devices mostly operate at a fixed angle. This fixed-angle extrusion port is unfavorable for the construction of plastic filler bulges, especially downward-facing extrusion ports, which hinder the free retreat of the forming device along the already constructed bulges. This often necessitates timely redesign and improvement based on specific project requirements, increasing investment. Utility Model Content

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0026] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0027] like Figure 1 , 2As shown in the figure, this application provides a plastic filler molding device for adjusting the pitch angle. The plastic filler molding device mainly includes a frame 1, a filler molding mechanism 2, an adjusting mechanism 3, and a driving mechanism 4. A portal frame 11 is mounted on the frame 1 and is fixedly connected to the frame 1, for example, by welding. The filler molding mechanism 2 is mounted on the frame 1 and includes a material cylinder 21 and a molding die 22, with the molding die 22 located at the end of the material cylinder 21. The adjusting mechanism 3 includes an adjusting screw 31, a nut 32, and a screw connector 33. The nut 32 is mounted on the portal frame 11, and the screw connector 33 is located near the molding die 22 and on the side wall of the material cylinder 21. One end of the adjusting screw 31 is connected to the screw connector 33, and the other end passes through the nut 32, with the adjusting screw 31 and the nut 32 threadedly connected. The driving mechanism 4 is mounted on the frame 1 and is drively connected to the filler molding mechanism 2.

[0028] Specifically, when adjusting, the adjusting mechanism 3 can rotate the nut 32, causing the threaded adjusting screw 31 to drive the material cylinder 21 to deflect up and down by a certain angle, thereby adjusting the pitch angle of the filler forming mechanism 2. Generally, the adjusting mechanism 3 can adjust the angle of the filler forming mechanism 2 to 60°. Taking the horizontal direction as 0°, the adjustable pitch angle is within the range of -30° to +30° to adapt to different construction angle requirements. This plastic filler forming device adjusts the pitch angle of the filler forming mechanism 2 through the adjusting mechanism 3, realizing the movement of the filler forming mechanism 2 within a certain angle range. This allows the plastic filler forming device to adapt to different angle requirements, reducing the impact of the construction environment on the extrusion operation, thus facilitating the construction of plastic filler bulges.

[0029] Furthermore, with the development of water conservancy construction in my country, dam heights have reached 200 meters. On the one hand, some concrete-faced rockfill dams are located in high-altitude and cold regions. Plastic fillers need to possess good fluidity and adhesion during construction, typically requiring extrusion under certain temperature conditions. Especially in areas with low temperatures, heating the extruder head with liquefied gas or gasoline torches before construction is dangerous, time-consuming, and labor-intensive. Therefore, the plastic filler forming device in this application can also heat the extruded plastic filler. Specifically, for example... Figure 1 , 2 As shown, in one specific embodiment, the filler forming mechanism 2 further includes a metal baffle 23, a heating resistance wire 24, and a variable frequency speed control box 25; the metal baffle 23 and the heating resistance wire 24 are disposed on the forming die head 22, the variable frequency speed control box 25 is disposed on the frame 1, and the variable frequency speed control box 25 is electrically connected to the heating resistance wire 24 through a wire 26. Generally, the heating resistance wire 24 heats the plastic filler in a temperature range of 0°C to 60°C.

[0030] The heating resistance wire 24 ensures rapid heating at the extruder outlet, guaranteeing optimal workability of the plastic filler under various climatic conditions, especially in low-temperature environments. This prevents the material from becoming too hard, improves extrusion and bonding effects, and avoids motor burnout due to excessively hard material at low temperatures. This plastic filler forming device combines real-time angle adjustment and pre-energization for temperature regulation, reducing the need for extruder replacement in different areas and the reliance on gas or blowtorch heating. This improves workability, ensures uniform material application, and guarantees the durability and stability of the joint sealing effect.

[0031] It should be noted that the heating resistance wire 24 can also be other electric heaters or other heating devices capable of heating plastic fillers. The heating resistance wire 24 is integrated into the outer surface of the mold of the filler forming mechanism 2, and is designed to be detachable. The temperature control range is 0℃ to 60℃, ensuring that the filler maintains good flowability and adhesion at a suitable temperature.

[0032] like Figure 1 As shown, in one specific embodiment, the side wall of the material cylinder 21 is provided with a feed inlet 27, which is square in design, and a corresponding metal cover plate is provided to open or close the feed inlet 27. A drive screw 28 and a conveying auger 29 are axially arranged inside the material cylinder 21; the drive mechanism 4 includes a drive motor, which is movably connected to the frame 1 through at least one connecting rotating shaft 5, and the output end of the drive motor is connected to the drive screw 28 and can drive the drive screw 28 to rotate.

[0033] like Figure 1 As shown, in one specific embodiment, flanges 20 are provided at both ends of the material cylinder 21 along the axial direction, and the forming die head 22 is connected to the material cylinder 21 through one of the flanges 20; multiple wheels 12 are provided at the bottom of the frame 1, and the wheels 12 are provided with locks that can brake or lock the wheels 12, that is, the wheels 12 have a locking function. The operator can easily move the device along the concrete structure joint and adjust its position using a winch, and stabilize the position of the equipment through the locking function. In addition, the frame 1 is made of high-strength alloy material, which has the characteristics of being lightweight and high-strength, which can reduce the weight of the entire machine body, facilitate transportation and transfer, and has good load-bearing capacity in its design, and can remain stable in harsh construction environments.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
