Description

Technical Field

[0001] This utility model belongs to the field of construction engineering and relates to a straightening device, particularly a hydraulic straightening device for pipe piles integrated into an excavator. Background Technology

[0002] In the field of building construction, prestressed pipe piles are widely used due to their advantages such as high bearing capacity and fast construction speed.

[0003] However, during or after pile driving, due to complex geological conditions, underground obstacles, and improper construction operations, pipe piles are prone to tilting, misalignment, and other quality problems. Traditional methods for straightening pipe piles typically rely on large lifting equipment with wire ropes for hoisting and correction, or on using manual hoists and jacks at adjacent pile locations for pushing. These traditional methods have many drawbacks: First, they require additional specialized equipment, resulting in high scheduling costs and large site requirements, and are limited by the available space on the construction site, leading to poor flexibility; second, manual hoists and other tools are cumbersome to operate, the force application process is unstable, making precise fine-tuning difficult and potentially causing secondary damage to the pile body.

[0004] In addition, there are some dedicated hydraulic alignment devices in the existing technology, but these devices are usually independent units that require separate transportation and installation, resulting in high overall construction costs and the inability to achieve efficient integration with the basic equipment (such as excavators) that are widely available on construction sites. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a hydraulic straightening device for pipe piles integrated into an excavator, thereby solving these problems.

[0006] The purpose of this utility model can be achieved through the following technical solution: a hydraulic straightening device for pipe piles integrated into an excavator, characterized in that it includes a control system connected to the excavator, a hydraulic device, a mounting platform fixedly installed at the front end of the excavator, and at least one mounting seat fixed on the mounting platform for supporting the hydraulic device. The hydraulic device includes a hydraulic cylinder and a piston rod driven by it. The free end of the piston rod is connected to a traction rope. A tension sensor for real-time monitoring of traction force is provided between the free end of the piston rod and the traction rope. A displacement sensor for monitoring the displacement distance of the piston rod is provided in the mounting base. The system controls the movement of the hydraulic cylinder and receives feedback signals from the tension sensor and displacement sensor to form a closed-loop control for the straightening operation of the pipe pile.

[0007] In the aforementioned hydraulic straightening device for pipe piles integrated into an excavator, the number of mounting seats is two or more, arranged at intervals along the axial direction of the hydraulic cylinder, and a displacement sensor is provided in one of the mounting seats near the free end of the piston rod.

[0008] In the aforementioned hydraulic straightening device for pipe piles integrated into an excavator, the other end of the traction rope is connected to a clamp for attaching the pipe pile.

[0009] In the aforementioned hydraulic straightening device for pipe piles integrated into an excavator, the control system can receive the target tension value and target displacement value set by the user, and automatically adjust the action of the hydraulic cylinder by comparing the feedback signal with the set value, so that the traction force and displacement are stabilized within the set range.

[0010] In the aforementioned hydraulic straightening device for pipe piles integrated into an excavator, the control system further includes an early warning module. When the traction force monitored by the tension sensor exceeds a preset safety threshold, the early warning module issues an audible and visual alarm and controls the hydraulic cylinder to stop operating or depressurize.

[0011] Compared with existing technologies, this hydraulic straightening device for pipe piles integrated into an excavator can finely adjust the straightening force and displacement, preventing damage to the pipe piles due to improper stress, ensuring construction quality and safety. Its control system can automatically maintain the set parameters, greatly reducing reliance on manpower, improving the level of standardization and efficiency of operations, and directly using the excavator as the working platform without calling up other special equipment. It also has overload warning and protection functions, with rapid overall response and significantly improved safety and reliability. Attached Figure Description

[0014] In the diagram, 1 is the mounting platform; 2 is the mounting base; 3 is the hydraulic cylinder; 4 is the piston rod; 5 is the traction rope; 6 is the tension sensor; 7 is the displacement sensor; and 8 is the excavator. Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2As shown, the hydraulic straightening device for pipe piles integrated into an excavator includes a control system connected to the excavator 8, a hydraulic device, a mounting platform 1 fixedly installed at the front end of the excavator 8, and at least one mounting base 2 fixed on the mounting platform 1 to support the hydraulic device. The hydraulic device includes a hydraulic cylinder 3 and a piston rod 4 driven by it. The free end of the piston rod 4 is connected to a traction rope 5. A tension sensor 6 for real-time monitoring of traction force is installed between the free end of the piston rod 4 and the traction rope 5. A displacement sensor 7 for monitoring the displacement distance of the piston rod 4 is installed in the mounting base 2. The control system controls the movement of the hydraulic cylinder 3 and receives feedback signals from the tension sensor 6 and the displacement sensor 7 to form a closed-loop control for pipe pile straightening operation.

[0017] The number of mounting seats 2 is two or more, arranged at intervals along the axial direction of the hydraulic cylinder 3. One mounting seat 2, near the free end of the piston rod 4, houses a displacement sensor 7. The other end of the traction rope 5 is connected to a clamp for the pipe pile. The control system can receive the target tension and displacement values ​​set by the user, and automatically adjust the action of the hydraulic cylinder 3 by comparing the feedback signal with the set values, stabilizing the traction force and displacement within the set range. The control system also includes a warning module. When the traction force monitored by the tension sensor 6 exceeds a preset safety threshold, the warning module issues an audible and visual alarm and controls the hydraulic cylinder 3 to stop operating or depressurize.

[0018] During operation, operators need to calculate the target values ​​in advance and set the target tension and displacement values ​​required for the straightening operation through the control system. After startup, hydraulic cylinder 3 drives piston rod 4 to extend, applying straightening tension to the tilted pipe pile through traction rope 5. During this process, tension sensor 6 monitors the actual tension of traction rope 5 in real time, and displacement sensor 7 monitors the extension and retraction of piston rod 4 in real time, indirectly reflecting the movement distance of the pipe pile. These two key parameters are continuously fed back to the control system. The control system compares the real-time data with the preset target values. Once a deviation occurs, such as insufficient tension or excessive displacement, it immediately issues a command to automatically and precisely adjust the action of hydraulic cylinder 3, such as pressurizing, holding, or depressurizing, dynamically adjusting the output force and displacement, so that the pipe pile can smoothly and accurately return to a vertical state according to the preset force and displacement parameters.

[0019] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
