Description

Technical Field

[0001] This invention relates to the field of square pile forming technology, specifically to a square pile forming device for municipal civil engineering projects. Background Technology

[0002] Prestressed high-strength concrete square piles (PHC square piles) are high-performance foundation components prefabricated in specialized factories and widely used in municipal civil engineering projects. Their core function is to reliably transfer the enormous loads of large structures such as high-rise buildings, bridges, and ports through weak soil layers to deep, solid bearing rock and soil. Square pile forming equipment is the core equipment for producing concrete square piles. It mainly uses molds and corresponding processes to process raw materials such as concrete and reinforcing steel into standardized square pile components. Among these processes, ensuring the compaction of the concrete material is one of the key techniques employed by the square pile forming equipment.

[0003] Currently, the mainstream compaction process in the industry is pedestal-type vibration, which involves installing multiple high-power, low-frequency vibratory motors on the bottom or side walls of a static, long-line formwork. The entire steel structure of the formwork vibrates as a whole, transferring energy to the concrete inside the cavity to achieve compaction. The inherent drawback of this process is its extremely low energy utilization rate. The vibration system needs to drive the entire formwork to vibrate, while the effective energy used for compacting the concrete is very small, resulting in significant energy waste and severe noise pollution. Furthermore, because the vibration energy inevitably attenuates as it travels along the formwork, which can be hundreds of meters long, the compaction effect is inconsistent between the ends and the middle of the formwork, making it difficult to guarantee the uniformity of the pile quality.

[0004] To address the aforementioned issues, some mobile forming equipment has emerged in the industry. This type of equipment integrates the vibration source onto a movable head, which vibrates the concrete synchronously as it moves. However, most existing mobile equipment relies on mechanical extrusion or low-frequency eccentric vibration to achieve compaction. These devices, due to excessive amplitude, can cause separation of aggregate and slurry, leading to concrete segregation and affecting the uniformity of the pile body. Furthermore, whether it's a pedestal-type vibrator or the existing mobile vibrator, the power output of the vibration system is usually constant. During the start-up, deceleration, or stopping phases of the mobile head, the fixed vibration energy cannot match the changing travel speed, causing localized vibration leakage in the pile body, resulting in lower mass at both ends of the square pile compared to the middle section. In conclusion, existing square pile forming technology still has certain problems in achieving high-quality, dense concrete forming. Achieving high-quality, dense concrete forming has become a technological development direction with clear application value in this field. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a square pile forming device for municipal civil engineering projects, which solves the problem that uneven vibration energy transmission in existing technologies prevents concrete materials from being formed into high-quality, dense concrete in the mold, resulting in local defects in the formed square piles.

[0017] The information acquisition unit is used to acquire real-time data from the level gauge and the speed sensor, and transmit the real-time data to the analysis and processing unit.

[0021] This invention provides a square pile forming device for municipal civil engineering projects. It has the following beneficial effects:

[0022] 1. This invention uses a vibrating plate to conduct controllable high-frequency oscillations generated by a high-frequency vibrator, causing shear thinning of the concrete. This allows the concrete to enter a fluidized state in local areas, fully filling all corners of the square pile mold, especially the right-angle area of ​​the Z-shaped demolding component. This solves the problem of local defects in square piles caused by uneven vibration energy transmission due to low-frequency vibration motors in the prior art.

[0023] 2. By setting up a movable component, and sequentially arranging a concrete pouring mechanism, a concrete fluidization mechanism, and a concrete finishing mechanism on the movable component along the moving direction, the present invention integrates the multiple distributed processes in the traditional square pile forming equipment into a movable integrated device, thereby optimizing the square pile production process and shortening the square pile forming cycle.

[0024] 3. This invention solves the problem of difficult demolding of piles under static mold beds by setting a bidirectional hydraulic cylinder and a Z-shaped demolding component inside the pile mold cavity. During demolding, the bidirectional hydraulic cylinder generates an outward lateral pulling force to make the square pile detach from the Z-shaped demolding component, thus avoiding damage to the surface of the square pile due to forced demolding.

[0048] Specifically, the collaborative control system 700 includes a central processing unit 710, which is installed outside the pile mold housing 211. The central processing unit 710 is specifically a control device connected to the Internet. The central processing unit 710 internally houses a control system, which includes: an information acquisition unit for acquiring real-time data from the level gauge 720 and speed sensor 730, and transmitting the real-time data to an analysis and processing unit; an analysis and processing unit with pre-set algorithms for analyzing and processing the information acquired by the information acquisition unit, and converting the processing results into electrical signals that are transmitted to the control and drive unit; and a control and drive unit for responding to the electrical signals transmitted by the analysis and processing unit. The system includes a drive pile forming mechanism 200 and a fluidization power regulator 740. A pair of level gauges 720 are installed on the inner wall of the gantry frame 310, a pair of speed sensors 730 are installed at the bottom of the gantry frame 310, and a fluidization power regulator 740 is installed at the top of the gantry frame 310. The level gauges 720 are specifically ultrasonic level gauges, which can monitor the flow rate of concrete materials without contact. The speed sensors 730 are used to monitor the moving speed of the gantry frame 310. The fluidization power regulator 740 is used to adjust the oscillation frequency of the high-frequency oscillator 412 to prevent excessive oscillation from causing aggregate separation of concrete materials, or insufficient oscillation from causing concrete materials to not completely fill the Z-shaped demolding component 220.

[0049] Working Principle: When using this square pile forming equipment, the construction personnel first spray concrete release agent on the inner side of the Z-shaped demolding component 220. Then, the steel reinforcement cage of the square pile is placed into the Z-shaped demolding component 220. Next, the motor is started, driving the roller 320 to move along the guide rail 212, which in turn moves the gantry 310 horizontally. Simultaneously, concrete material is introduced into the feed inlet 510 through external pipelines. The concrete material flows out evenly after passing through the guide cavity 520 and the distributor 530, distributing itself inside the Z-shaped demolding component 220. During this process, the high-frequency oscillator 412 continuously generates high-frequency oscillations, driving the electric push rod 413 to cause the vibrating plate 414 to enter the concrete material. Under the action of high-frequency oscillation, the concrete material undergoes shear thinning and enters a fluidized state. The fluidized concrete material fully covers the Z-shaped demolding assembly 220. At this time, the hydraulic rod 610 drives the L-shaped push plate 620 to move downward until it is close to the top plate 223 of the demolding formwork. The L-shaped push plate 620 pushes the concrete material overflowing from the Z-shaped demolding assembly 220 to both sides of the top plate 223 of the demolding formwork along the forward direction of the gantry 310. At the same time, the L-shaped protrusion prevents the material from falling out from the tail. When the gantry 310 reaches the end point, the concrete pouring operation of the square pile is completed. After waiting for the square pile to dry and form, the bidirectional hydraulic cylinder 230 is activated. The bidirectional hydraulic cylinder 230 drives the Z-shaped demolding assembly 220 to move to both sides. With the assistance of the release agent, the square pile is demolded by horizontal pulling. Then, the construction personnel use external equipment to lift and remove the square pile, completing the forming work of the square pile.

[0050] During the square pile forming process, the level gauge 720 monitors the flow rate of concrete material in real time and feeds it back to the central processing unit 710. The speed sensor 730 monitors the moving speed of the gantry 310 in real time and feeds it back to the central processing unit 710. The central processing unit 710 uses a built-in algorithm to incorporate the flow rate of concrete material and the moving speed of the gantry 310 to control the rotation speed of the roller 320, thereby matching the moving speed of the gantry 310 with the flow rate of concrete material. In addition, the central processing unit 710 also adjusts the oscillation frequency of the high-frequency oscillator 412 in real time through the fluidization power regulator 740 according to the moving speed of the gantry 310. The oscillation frequency of the high-frequency oscillator 412 on the outer wall is higher than that of the high-frequency oscillator 412 in the center. During the square pile forming process, the bidirectional hydraulic cylinder 230, the electric push rod 413, and the hydraulic rod 610 are all controlled by the central processing unit 710.
