Description

Technical Field

[0001] The present invention relates to the technical field of foundation treatment construction equipment, and more specifically, to an electromagnetic acceleration pile driving device for foundation treatment. Background Art

[0002] In the transportation road network of our country, high-speed railway lines represented by the Lanzhou-Xinjiang line and the Zhengzhou-Taiyuan line pass through vast areas of collapsible loess regions. The construction and operation of roads, railways and other buildings in this area will also face the challenge of collapsible deformation of loess. Therefore, in the foundation treatment during the design and construction period, especially the elimination of collapsibility of loess, is of great significance to the long-term serviceability of the entire structure.

[0003] Currently, the mainstream treatment methods for collapsibility are dynamic compaction, lime soil compaction piles and column hammer punch-expansion piles. These foundation treatment methods all need to lift the hammer height and convert the gravitational potential energy into kinetic energy, and then the kinetic energy is transmitted to the foundation soil (dynamic compaction), the pile body (compaction pile, punch-expansion pile). Then the soil body is extruded, thereby weakening and eliminating the collapsibility of loess, and at the same time, the foundation bearing capacity is improved. The existing foundation treatment loading equipment has the following problems in engineering practice:

[0004] (1) The mainstream construction machinery for compaction piles is a winch. Its foundation treatment effect under the action of conventional gravity mainly depends on the maximum allowable hammer weight and the maximum drop distance. In engineering practice, the height of the winch mostly exceeds 20 meters. During the processes of site cleaning, transportation, installation and commissioning, and formal construction of the machinery, a safety operation area needs to be demarcated for the operation environment of the construction machinery, and the size of the area is also affected by the height of the winch. After completing a construction operation, the movement of the machinery is also relatively inefficient. The size of the safety operation area of the winch also restricts the number of construction platforms for the entire project and limits the construction efficiency of the project.

[0005] (3) Due to the height of the winch, it can meet the wind resistance requirements under normal use conditions, but the construction under medium and strong wind conditions faces severe safety challenges. In addition, for compaction piles and column hammer punch-expansion piles, it is required that both the compaction coefficient of the soil in the pile hole and the compaction coefficient between the pile holes reach the design requirements. However, due to the cost of wind resistance and anti-tipping measures required for the winch lifting height, the energy level of the tamping energy can only be in a relatively economical parameter range. Therefore, only by increasing the number of tamping times can the construction quality be guaranteed, which also limits the further improvement of efficiency from the aspect of the efficiency of construction machinery.

[0006] Patent "Compaction Pile Driving Device for Foundation Treatment", authorization number CN115852957B. This patent improves the traditional compaction pile driver by adding a radial buffer spring pad group to the fixed ring of the pile driver. This cushion layer is used to absorb vibration, reduce the reverse vibration impact of the rammer impact on the entire pile driving machinery, and reduce the noise level in the operation area, improving the construction environment. In addition, the introduction of the buffer cushion layer enhances the radial constraint on the rammer, further improving construction safety. The disadvantage is that the energy utilization form and efficiency of this equipment tend to be single and the equipment volume is relatively large, resulting in constraints on efficiency and operation space in engineering practice, which further restricts the further promotion and use of pile driving equipment.

[0007] Patent "A Pile Driving Device", authorization number CN221276595U. This patent proposes a pile driving device equipped with a mobile base, a support frame, and an adjustable forward and reverse threaded rod, which can achieve high-precision adjustment during the pile driving process. Through the first motor and the forward and reverse threaded rod installed on the support frame, the position of the moving block can be accurately controlled, thus ensuring the accuracy during pile driving and avoiding deviation. By setting structures such as clamping blocks and limiting cylinders, the stability and control of the pile position during the pile driving process are further enhanced. The advantage of this patent is to improve the positioning accuracy and construction stability of the pile driving device, while the disadvantage is that the energy utilization form is single and it cannot improve the construction efficiency of the pile driving device.

[0008] Therefore, how to provide an electromagnetic acceleration pile driving device for foundation treatment that can reduce the safety maintenance cost of construction operations and improve the construction efficiency of pile driving devices is an urgent problem for those skilled in the art.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figures 1-7 , an electromagnetic acceleration pile driving device for foundation treatment disclosed in an embodiment of the present invention includes:

[0035] A support base 1, a full-terrain crawler 2 is provided at the bottom of the support base 1, and a support frame 3 is provided on the support base 1. One end of the support frame 3 is close to the support base 1; the full-terrain crawler 2 has the advantages of wide application range, simple structure, stable transmission and labor-saving operation, and can better perform construction operations on adverse terrains such as river beaches, swamps, and slopes in the engineering practice of foundation treatment; cooperating with the power motor, the crawler has excellent climbing and ground-gripping performance, a safe climbing angle of 20 degrees, a small turning radius, and is flexible and adaptable, especially suitable for construction operations in narrow sites;

[0036] Two accelerating body 51 fixing clamps 4 are provided in the vertical direction. Each accelerating body 51 fixing clamp 4 includes a fixed layer base 41 and a clamping damping adjuster 42. The fixed layer base 41 is connected to the support frame 3. A clamping base 43 is provided at one end of the fixed layer base 41 away from the support frame 3. N clamping damping adjusters 42 are provided, N≥2, and the clamping damping adjusters 42 are evenly distributed in a circle in the clamping base 43. A contact clip 44 is provided at one end of each clamping damping adjuster 42 away from the clamping base 43; the connection between the fixed layer base 41 and the support frame 3 provides support and fixation for the clamping base 43. The size of the contact clip 44 can be adjusted according to the actual size of the accelerating body 51. After the accelerating body 51 is hoisted, the clamping damping adjuster 42 is adjusted to ensure that the contact clip 44 is in full contact with the accelerating body 51; after the equipment is fully charged, while turning on the LGBT switch, the clamping damping adjuster 42 retracts to release the clamping restraint on the accelerating body 51; after the acceleration is completed, after hoisting the accelerating body 51 back, the clamping damping adjuster 42 is adjusted again to clamp the accelerating body 51, and repeating the above operations can successively achieve foundation treatment.

[0037] An electromagnetic acceleration device 5, and the electromagnetic acceleration device 5 is fixed in the clamping base 43 through the contact clip 44.

[0038] In this embodiment, the electromagnetic acceleration device 5 includes an acceleration body 51 and an acceleration body coil protection housing. A number of electromagnetic coils 52 are wound around the acceleration body 51. Both the acceleration body 51 and the electromagnetic coils 52 are located inside the acceleration body coil protection housing. The acceleration body coil protection housing includes an upper coil protection housing segment 53, a middle coil protection housing segment 54, and a lower coil protection housing segment 55. Reinforcing ribs 56 are provided at the joints of the upper coil protection housing segment 53, the middle coil protection housing segment 54, and the lower coil protection housing segment 55. The electromagnetic coils 52 adopt multi-layer spiral coils, and the number of turns and wire diameter are determined according to the circuit design diagram. The reinforcing ribs 56 are provided to enhance the overall stability. The housing is subjected to a process treatment to maximize the improvement of the magnetic characteristics of the protection housing, weaken the magnetic leakage phenomenon, and thus ensure the energy utilization of the strong magnetic field generated by the electromagnetic coils 52.

[0039] In this embodiment, the electromagnetic coils 52 are wound around the acceleration body 51 in a bundled multi-layer winding manner. A safety gap is reserved between the acceleration body 51 and the innermost circle of the electromagnetic coils 52, and the acceleration direction is vertically downward. The magnetic field strength and magnetic characteristics are improved. As Figure 3 shown, the spatial arrangement forms of the electromagnetic coils i, electromagnetic coils j, and electromagnetic coils k in the form of a three-layer bundled winding are presented.

[0040] In this embodiment, it further includes an operation room 6 and an ultra-high energy power generation set 7. Both the operation room 6 and the ultra-high energy power generation set 7 are arranged on the support base 1. The operation room 6 is arranged close to the support frame 3.

[0041] In this embodiment, it further includes extension supports 8. A number of extension supports 8 are provided, and all the extension supports 8 are connected to the support base 1 to improve the stability of the support.

[0042] In this embodiment, it further includes a hoisting system. The hoisting system is arranged on the support base 1. The hoisting system consists of a pulley block, a steel cable, an electric winch, a lifting ring, and a power motor. The acceleration body 51 is hoisted through the hoisting system.

[0043] In addition, in this embodiment, the principle of the electromagnetic acceleration device 5: The electromagnetic acceleration system stores the electrical energy of a high-voltage power supply in a capacitor and then quickly releases it to generate an instantaneous strong magnetic field through the coil. This magnetic field exerts a Lorentz force on the conductor located inside the coil, causing it to accelerate along the axis, thereby realizing the conversion of electrical energy into kinetic energy and further realizing the utilization of various energy forms. The basic scientific knowledge involved in the principle part is described as follows:

[0044] F = q(E + v×B)

[0045] where F is the Lorentz force, q is the electric charge, E is the electric field strength, v is the velocity vector, and B is the magnetic induction intensity.

[0046]

[0047] Among them, KE is the kinetic energy, m is the mass of the projectile, and v is the velocity.

[0048]

[0049] Among them, ε is the induced electromotive force and Φ is the magnetic flux.

[0050]

[0051] Among them, E is the energy stored in the capacitor, C is the capacitance, and V is the voltage.

[0052]

[0053] Among them, F is the frequency of the oscillating circuit, and the resonant frequency of the circuit is determined by the inductance L and the capacitance C.

[0054] The electromagnetic acceleration system needs to generate a sufficiently high instantaneous current in a short time, so a circuit design scheme of an LC oscillating circuit is adopted.

[0055] The capacitor bank is used to store and quickly release electric energy. When selecting, its capacity and withstand voltage characteristics need to be considered. The control switch system of the circuit uses an FPGA to generate PWM signals to control the on and off of the IGBT. The main advantages of FPGA control are as follows: The parallel processing ability of the FPGA allows multiple signals to be processed simultaneously; the nanosecond-level reaction speed is suitable for high-frequency switching applications; it supports multiple communication protocols, is easy to integrate, supports the adjustment of parameters such as custom pulse width and frequency; in addition, the switch system using the FPGA can implement a digital filter to remove noise and improve signal quality; according to the load change, an adaptive algorithm is written to dynamically adjust the control strategy to achieve the best performance; the ADC (analog-to-digital converter) interface is used to convert analog signals such as current and voltage into digital signals, and the operation status of the electromagnetic acceleration system can be intuitively fed back during actual construction operations; the high-energy motor adopts the Siemens 1LE0001 series motor, and the main parameters are: rated power: 50kW, rated voltage: 400V, rated current: 92A, efficiency: 95%, speed: 1490rpm, frequency: 50Hz, insulation class: F, protection class: IP55.

[0056] The power supply design of the circuit uses a pulse power source to achieve the ability to provide high current and high voltage within an extremely short time, meeting the requirements of the electromagnetic acceleration device 5 for high-power pulses; an array is formed by connecting multiple capacitors in parallel or in series to enhance the energy storage and rapid release capabilities, significantly improving the discharge efficiency and energy transmission ability of the circuit during the pulse power release process; at the same time, a high-frequency transformer or a power isolation module is used to ensure the stability of the current and voltage, effectively avoiding the impact of power supply voltage fluctuations on the system and ensuring the stability and reliability of the electromagnetic acceleration device 5 under high-load operation; in addition, series input filter capacitors are used for filtering to ensure smooth power supply input and reduce noise, and a bridge rectifier circuit (bridge rectifier diodes) composed of four diodes is used to convert the boosted AC voltage into DC power;

[0057] The high-speed switching device uses IGBT to control the switch, which can quickly switch the current to ensure that the energy of the capacitor can be quickly released into the electromagnetic coil 52;

[0058] The LC oscillation circuit (inductor L and capacitor C) can store and release electrical energy to form a stable current pulse. By adopting a suitable matching of the inductor and capacitor in the circuit and optimizing the resonance frequency of the LC, the electrical energy release efficiency can be improved, enabling the electromagnetic acceleration device 5 to generate a greater acceleration within a shorter time;

[0059] The inductor L uses a multi-layer coil. By increasing the number and layers of the coils, the density of the magnetic field can be increased, and the wire is wound into a spiral shape to increase the concentration of the electromagnetic field. By adjusting the direction of the current between each layer of the coils, the electromagnetic force can be further enhanced, improving the acceleration effect;

[0060] The large-capacity energy storage capacitor (C2) is mainly used to store and release high energy to drive the electromagnetic coil 52 to generate a strong magnetic field. The large-capacity capacitor can store more electrical energy and quickly release it to generate a strong magnetic field when needed, improving the acceleration effect, but it also requires a longer charging time. Therefore, the selection of the capacitor needs to balance the charge and discharge time, system power requirements, and response speed to achieve good acceleration performance. To meet the high-power requirements, capacitors with a capacitance of 10,000 μF to 100,000 μF are selected. The voltage of the capacitor needs to be higher than the maximum input voltage of the system. To ensure safety and stable operation of the system, the voltage rating of the capacitor should be at least 1.5 times the working voltage. In addition, the durability and temperature characteristics of the capacitor have a significant impact on the stability and service life of the capacitor in a high-voltage and high-power application environment;

[0061] The voltage of the LC oscillation circuit is relatively high, and situations such as excessive current and short circuit are likely to occur. It is necessary to design additional overcurrent protection, such as fuses or current sensors, to prevent circuit damage. For example, a fast recovery diode is used in the design to prevent current reflux and protect the stability of the capacitor and the circuit. In addition, a metal oxide varistor (MOV) is added to avoid circuit damage caused by excessive voltage. In addition, a current sensor is added to the electromagnetic acceleration device 5 to monitor the working circuit parameters of the circuit, which can prevent components such as capacitors and wires from being burned by excessive current;

[0062] Circuit operation process:

[0063] First, turn on the AC power supply U1. The AC current passes through the filter capacitor C1 for filtering to remove clutter and noise, ensuring the stability of the input DC voltage. The filtered current enters the rectifier diode D2(a), and the alternating current is converted into direct current through the rectification process, and then the energy storage capacitor C2 is charged. After the capacitor C2 is fully charged, the system is ready to release the stored energy. At this time, the control switch LGBT is turned on, and the high voltage stored in the capacitor is instantaneously released and quickly applied to the electromagnetic coil 52L, exciting a strong magnetic field. The inductor L and the capacitor C2 form an efficient energy exchange system in the loop. When the capacitor C2 discharges through the switch, electrical energy is quickly transmitted to the electromagnetic coil 52L, generating an instantaneous high current, and then a strong magnetic field is generated inside the electromagnetic coil 52. Due to the characteristics of the inductor L, the magnetic field strength is closely related to the current change rate. A rapid change in current will enhance the magnetic field, thereby improving the acceleration effect. After the high voltage is applied to the electromagnetic coil 52, the fast recovery diode D3 can quickly conduct to prevent the reverse current generated by the high voltage from flowing back to the power supply or other sensitive components, thus protecting the entire circuit from damage. In addition, the diodes D2(b), D2(c), and D2(d) together form a bridge rectifier circuit to ensure that the current only flows in a single direction in the circuit, avoiding damage to the power supply, energy storage capacitor, and other components caused by reverse current.

[0064] The LC oscillation characteristics enable energy to be efficiently transmitted from the energy storage capacitor C2 to the electromagnetic coil 52L, quickly generating a high-intensity magnetic field to accelerate the target object. The diode protection circuit effectively avoids damage caused by current reverse reflux and high voltage, thus ensuring the stability and safe operation of the circuit under high-load conditions.

[0065] The support base 1 is made of high-strength alloy steel.

[0066] The drive wheel 9 is provided in the all-terrain track 2 to drive the all-terrain track 2 to move.

[0067] Specific operation method

[0068] 1. Before the equipment is brought to the site, the site should be leveled as much as possible to provide the best possible environment for the normal operation of the equipment. In addition, if there are multiple working surfaces, the working areas should be reasonably planned to achieve the best utilization of the site.

[0069] 2. Rationally plan the equipment's arrival and layout. Based on practical engineering considerations, use methods such as engineering Gantt charts and regional radar charts to ensure that the equipment's arrival is not affected by construction operations and other conditions. After the equipment arrives on site, set up a working cordon to prevent unauthorized personnel from accidentally entering during subsequent operations and causing danger.

[0070] 3. After the foundation operation area is marked, the driver needs to adjust the equipment position to reach the designated target impact point;

[0071] 4. After positioning is completed, in order to enhance the stability and load-bearing capacity of the equipment, expand the extension support 8 if conditions permit, expand the force-bearing area, thereby reducing the load pressure of the engineering operation on the ground area, thereby effectively reducing the load level on the working surface;

[0072] 5. The operator checks the operating status of each equipment system. First, ensure that the status of the core systems such as the support system, ultra-high energy generator set 7, system circuit, and electromagnetic acceleration device 5 reaches the operating state. Then check the remaining subsystems. Only when all systems meet the working conditions can the next operation be carried out;

[0073] 6. When hoisting the accelerator 51, pay attention to the possibility of tilting, overturning, slipping, etc. during the hoisting process of the accelerator 51, and reasonably plan the lifting point, lifting speed, lifting angle, and even the posture control of the accelerator 51 during the entire lifting process;

[0074] 7. Acceleration parameters are preset in the control circuit. By setting a series of key control parameters such as pre-charge percentage, ultra-high energy generator set 7 power, LGBT electronic control parameters, etc., specialized adjustments can be made based on specific project conditions, kinetic energy requirements, and operating depth, thereby achieving optimal construction benefits;

[0075] 8. Before starting the ultra-high energy generator set 7, check whether the fuel reserve in the fuel tank of the ultra-high energy generator set 7 meets the operating requirements. If the operating volume is large, it is necessary to adopt an oil tank oil supply plan to ensure uninterrupted operation throughout the entire process. After starting the ultra-high energy generator set 7, perform pre-charging and check the working performance of the energy storage device and the ultra-high energy generator set 7. If a single unit stalls or a capacitor fails during operation, promptly cut off the ultra-high energy generator set 7 and find out the cause. If the equipment is operating normally and the circuit parameters are stable, then enter the full charging stage to reduce human disturbance to the equipment during the process.

[0076] 9. After the charging is completed, start the preset LGBT control scheme, and at the same time release the fixed clamping constraint of the accelerator body 51. After experiencing the opening moment, the continuous current moment, and the recovery moment, the accelerator body 51 completes the acceleration, the LGBT automatically disconnects, and the electromagnetic coil 52 enters the cooling state;

[0077] 10. Hoist the accelerator body 51 back, check the ramming effect of this time to optimize the parameter settings. After the electromagnetic coil 52 is cooled, the above steps 5-9 can be repeated until the foundation treatment operation is completed.
