Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction equipment technology, and in particular to a water channel forming machine that integrates channel opening and sliding membrane. Background Technology

[0002] In traditional water conservancy projects, canal construction typically involves first using specialized canal-digging machinery to excavate the canal. Once the canal has been excavated and reached a certain size, slipform equipment is then used to form the concrete inner wall of the canal. This step-by-step construction method has many drawbacks:

[0003] First, the investment of multiple pieces of equipment increases construction costs, including equipment purchase costs, transportation costs, maintenance costs, and labor costs for operators. Second, the switching between different pieces of equipment requires a significant amount of time and effort. The processes of equipment entry, exit, debugging, and construction coordination are not only cumbersome but also prone to coordination errors, leading to delays in the construction schedule. Furthermore, phased construction makes it difficult to ensure the continuity and consistency of the entire canal construction process. Quality defects are prone to occur at the junction of canal opening and slipform operations, such as uneven canal walls and poor concrete bonding, affecting the overall performance and service life of the canal. Therefore, developing a canal forming machine that integrates canal opening and slipform operations is of great practical significance. Utility Model Content

[0033] In the above scheme, the sliding membrane support 5 is connected to the frame through the connecting mechanism 6.

[0034] Body: As the fundamental load-bearing component of the entire canal forming machine, the body is welded from high-strength alloy steel, possessing sufficient rigidity and strength to withstand various stresses and vibrations generated during canal opening and sliding sheeting operations. The body's design balances equipment stability and mobility, and its bottom is equipped with heavy-duty rubber tracks, enabling it to adapt to various complex terrain conditions, such as soft soil, rugged mountains, and muddy construction sites, ensuring smooth operation and advancement of the equipment during construction.

[0035] Power System 2: The power system is the core driving force for equipment operation, and different types of power sources can be selected according to actual construction needs and site conditions. For construction areas with relatively stable power supply and high environmental protection requirements, high-power electric motors can be used. Electric motors have advantages such as smooth starting, low operating noise, and simple maintenance, and can provide continuous and stable torque output to meet the power requirements of the equipment during canal opening and sliding sheet operations. In some remote areas or construction sites with inconvenient power supply, diesel engines can be selected as the power system. Diesel engines are characterized by high power and strong adaptability, and can work normally in harsh environments to ensure the continuous operation of the equipment. The power system is connected to other working components through a precision transmission device, efficiently transmitting power to the canal opening device and the sliding sheet device, ensuring the coordinated operation of all parts of the equipment.

[0036] 2. Detailed Structure and Function of the Channel Opening Device

[0037] Channel Opening Cutter 3: The channel opening cutter is a key component that directly interacts with soil and rock, manufactured from a specially customized cemented carbide material. This cemented carbide possesses extremely high hardness, wear resistance, and impact toughness, maintaining excellent cutting performance under various complex geological conditions. The cutting edge design has been meticulously optimized, employing a unique serrated or helical structure, effectively improving cutting efficiency, reducing friction and resistance between the cutter and the soil and rock, minimizing cutter wear, and extending cutter life. Furthermore, the shape and size of the channel opening cutter can be adjusted and replaced according to different channel design requirements. For example, a flat cutter can be used for wide and shallow channels, while a tapered cutter can be used for deep and narrow channels, ensuring precise excavation of a channel shape that meets design standards.

[0038] Cutter Rotation Mechanism 4: To meet the excavation needs of channels with different shapes, especially when excavating curved canals, the cutter rotation mechanism plays a crucial role. This mechanism employs an advanced combination of slewing bearing and drive motor, enabling the cutting tool to rotate freely 360 degrees in the horizontal plane. Operators can precisely set the rotation angle and speed of the cutter according to the designed curve of the canal through the control system, allowing the cutting tool to perform cutting operations along a predetermined curved trajectory during its advance, thus efficiently excavating canals of various complex shapes. The cutter rotation mechanism is also equipped with a high-precision angle sensor and position feedback device, which can monitor the rotation angle and position information of the cutter in real time and feed this information back to the control system, allowing operators to adjust and correct operating parameters in a timely manner, ensuring the accuracy and quality of curved canal excavation.

[0039] Innovative Design and Working Principle of Slippery Mechanism

[0040] 5. The slipform support, serving as the basic frame of the slipform device, is made of high-strength aluminum alloy, featuring lightweight, high strength, and corrosion resistance. The support's structural design has been mechanically optimized, possessing excellent stability and load-bearing capacity, and can adapt to the installation requirements of replaceable molds of different specifications and shapes. The universal slipform support is connected to the machine body using an adjustable connection method. Through bolts and a slide rail structure, the front-to-back position and horizontal height of the slipform support on the machine body can be easily adjusted to ensure precise connection between slipform operations and canal opening operations, and to adapt to the construction requirements of canals with different depths and slopes.

[0041] Replaceable Mold 8: The replaceable mold is one of the core features of the sliding membrane device of this invention. It adopts a modular design concept, allowing for rapid replacement according to different channel types and design requirements. The mold is made of high-quality stainless steel or high-strength engineering plastic, possessing excellent wear resistance, corrosion resistance, and demolding performance. For example, for common U-shaped channels, a specialized U-shaped mold can be designed. The inner wall surface of the mold undergoes fine processing and polishing, ensuring a smooth and flat inner wall of the channel after sliding membrane formation, reducing water flow resistance. For trapezoidal channels, a corresponding trapezoidal mold can be equipped. The angles of the mold's side plates and bottom plate can be precisely adjusted according to design requirements, ensuring that the formed channel meets engineering standards. The connection between the replaceable mold and the universal sliding membrane support adopts a convenient snap-fit ​​or plug-in structure, allowing for mold replacement in a short time without the need for complex tools, greatly improving the equipment's versatility and construction efficiency.

[0042] Mold Vibration Mechanism 9: The mold vibration mechanism is installed on the outer wall of the replaceable mold. Its main function is to vibrate and compact the concrete inside the mold during the slipform molding process. This mechanism uses a high-frequency vibration motor as the power source. The vibration motor is connected to the mold through a specially designed elastic connector, which can evenly and effectively transmit vibration energy to the concrete inside the mold. During the concrete pouring process, the mold vibration mechanism operates according to the predetermined vibration frequency and amplitude, causing the concrete to vibrate strongly within the mold, eliminating air bubbles and voids in the concrete, and improving the density and strength of the concrete. At the same time, the mold vibration mechanism is also equipped with vibration frequency and amplitude adjustment devices. Operators can flexibly adjust the vibration parameters according to factors such as the concrete mix ratio, pouring speed, and the shape and size of the mold to achieve the best slipform molding effect.

[0043] Concrete Delivery System 10: The concrete delivery system is responsible for transporting the mixed concrete from the storage tank or mixer truck to the replaceable molds of the slipform assembly. This system mainly consists of a concrete delivery pump, delivery pipelines, and a flow control device. The concrete delivery pump uses a high-power plunger pump or screw pump, capable of providing sufficient pressure to deliver concrete over long distances and to high heights, meeting the needs of different construction sites. The delivery pipeline uses high-strength wear-resistant steel pipes or rubber hoses, with the inner diameter and length rationally selected based on the equipment's delivery capacity and the layout of the construction site. The flow control device is installed on the delivery pipeline, precisely controlling the concrete delivery flow rate and velocity by adjusting the valve opening or using variable frequency speed control technology, ensuring that the concrete flows into the molds uniformly and stably, avoiding slipform defects or construction interruptions caused by excessive or insufficient flow.

[0044] In the actual construction process, the construction technicians first determine the depth, width, shape of the canal, as well as the thickness and strength of the slurry membrane, based on the design drawings and engineering requirements of the canal.

[0045] Before starting the equipment, operators should conduct a comprehensive inspection and debugging, including checking whether the fuel or electricity supply of the power system is sufficient, whether the channel cutting tools are securely installed and sharp, whether the replaceable molds of the slipform device meet the design requirements, whether the pipelines of the concrete conveying system are unobstructed, and whether the various functions of the control system are normal.

[0046] After confirming that the equipment is functioning normally, the power system is started, and the equipment begins to move forward slowly. Simultaneously, the cutter lifting mechanism of the canal-opening device lowers the cutter to a suitable position according to the preset canal-opening depth, and the cutter rotation mechanism adjusts the initial rotation angle of the cutter according to the designed curved trajectory. As the equipment advances, the canal-opening cutter begins to cut into the soil or rock to perform canal-opening operations. During the canal-opening process, the operator closely monitors the working status and digging progress of the canal-opening cutter through the control panel, adjusting the cutter depth and rotation angle as needed to ensure the accuracy and quality of the canal opening.

[0047] Once the canal excavation reaches the predetermined length or a construction section is completed, the equipment stops advancing. Operators select appropriate replaceable molds based on the canal's slipform requirements and quickly install them onto the universal slipform support. After installation, the installation accuracy and connection strength of the molds are checked again, as well as the readiness of the concrete conveying system.

[0048] The concrete conveying system of the slipform apparatus is activated, delivering the mixed concrete to the replaceable mold at a preset flow rate and velocity. Simultaneously, the mold vibration mechanism begins operation, vibrating and compacting the concrete within the mold according to the set vibration frequency and amplitude. During the slipform operation, the operator monitors parameters such as concrete delivery, the filling height of the concrete within the mold, and the vibration effect in real time via a control console. As needed, the operator adjusts the flow control device of the concrete conveying system and the vibration parameters of the mold vibration mechanism to ensure that the quality and thickness of the slipform molding meet design requirements.

[0049] Throughout the construction process, the fault diagnosis and alarm functions of the control system remain operational, monitoring the operation of all key components and systems in real time. In the event of a fault or abnormality, operators receive timely alarm information, quickly take appropriate repair measures, and resume construction after troubleshooting.
