[0017] 2.

Specific embodiments

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

[0025] Please refer to Figures 1-7 , the present invention provides a technical solution: a pulse cooperative adaptive regulation type high-efficiency pile driving device for road and bridge geology, including a vertical guide rail 1. The vertical guide rail 1 is one of the components of the body of an existing pile driver, and will not be elaborated in this case. The installation part 2 of this case is installed on the side wall of the vertical guide rail 1 and is used to install the ground pulse tool. The pulse part 3 of this case is installed on the installation part 2 and is used to automatically emit pulsed current intermittently to break the rock formation. The pile driving part 4 of this case is installed on the vertical guide rail 1 and is used for road surface pile driving and hole opening. The buffer part 5 of this case is installed on the pile driving part 4 and is used to buffer the pile driving vibration force received by the pulse part 3.

[0026] In the present invention, in order to more easily adapt to the pulse tool related to this case, the installation part 2 includes two installation feet 21. Both installation feet 21 are installed on one side of the vertical guide rail 1. The ends of the two installation feet 21 are fixedly connected with a U-shaped frame 22. Two jacks are opened on each ear end of the U-shaped frame 22. A support rod 23 is fixedly connected to the top surface of one ear end of the U-shaped frame 22. The number of support rods 23 is six in total. Every three support rods 23 are respectively arranged around one jack. The tops of every three adjacent support rods 23 are fixedly connected with a limit cover 24. A wire threading frame 25 is fixedly connected to the side wall of the U-shaped frame 25 and is used to thread the cable to avoid entanglement. A frame 26 is fixedly connected between the two installation feet 21. The number of installation parts 2 is two. The two installation feet 21 of the other installation part 2 are installed on the other side of the vertical guide rail 1. The two installation parts 2 are symmetrically arranged with each other.

[0027] In this embodiment, in order to utilize the pile driving frequency to call the pulsed current in real time to process the road surface, the pulse part 3 of this case includes two insulating columns 31. The two insulating columns 31 are respectively inserted into the inner walls of two aligned jacks between the ear ends of the U-shaped frame 22 of the installation part 2 on one side. Rod grooves are provided at the bottoms of the two insulating columns 31, and an electrode 32 is fixedly connected to the inner wall of each rod groove. Shock pads 33 are fixedly connected to the tops of the two insulating columns 31. A high-voltage generator 34 is installed on the frame 26. The TP3020 high-voltage pulse power supply is used to be connected to the mains electricity during road and bridge construction. High-voltage insulating cables 35 are connected between the high-voltage generator 34 and the two insulating columns 31. The two high-voltage insulating cables 35 both pass through the wire threading frame 25 and are respectively electrically connected to the two electrodes 32. There are two pulse parts 3, and the other pulse part 3 is installed on the other installation part 2. The two pulse parts 3 are symmetrically arranged with each other.

[0028] It should be noted that the pile driving part 4 of this case includes a pile frame 41. The pile frame 41 is installed on the moving end of the vertical guide rail 1. A hammer head 42 is slidably connected to the inner wall of the pile frame 41. A lifting oil cylinder 43 is installed in the pile frame 41. The telescopic end of the lifting oil cylinder 43 is fixedly connected to the hammer head 42. A pile head 44 is inserted at the bottom of the pile frame 41, and the end of the pile head 44 is in contact connection with the hammer head 42.

[0029] In order to further improve the stability and safety of pile driving, the buffer part 5 of this case includes a T-shaped plate 51. The T-shaped plate 51 is fixedly connected to one side of the hammer head 42. Two buffer columns 52 are slidably penetrated through the T-shaped plate 51. Limit pieces 53 are fixedly connected to the tops of the two buffer columns 52. Tension springs 54 are elastically connected between the two limit pieces 53 and the T-shaped plate 51. The two tension springs 54 are respectively sleeved on the two buffer columns 52. A positioning plate 55 is fixedly connected to one side of the outer wall of the pile frame 41. A distance sensor 56 is installed on the positioning plate 55. The LD80X laser infrared ranging module is adopted. There are two buffer parts 5. The T-shaped plate 51 of the other buffer part 5 is fixedly connected to the other side of the pile frame 41. The two buffer parts 5 are symmetrically arranged with each other.

[0030] It should be noted that the two buffer columns 52 in each buffer part 5 are respectively aligned with the two insulating columns 31 on the same side. The top end of each insulating column 31 is respectively located between three adjacent struts 23 of itself. The bottom end of each buffer column 52 is of an arc surface structure. Each buffer column 52 respectively passes through the corresponding limit cover 24 and abuts against the shock pad 33 aligned with it. The struts 23 and the limit covers 24 can further ensure the stability of the lifting of the pile frame 41 and improve the working safety. Microcontrollers are electrically connected to both of the two high-voltage generators 34. The distance sensors 56 in each buffer part 5 are respectively electrically connected to the microcontrollers on the same side. Each distance sensor 56 is respectively aligned with the adjacent T-shaped plate 51 of itself.

[0031] Working principle: The moving end of the vertical guide rail 1 lifts the pile frame 41 to a high position. The insulating columns 31 on the two U-shaped frames 22 are perpendicular to the road surface, prompting the electrodes 32 to contact the road surface. The lifting oil cylinder 43 drives the hammer head 42 to reciprocate up and down, prompting the hammer head 42 to repeatedly strike the pile head 44, thereby performing drilling operations on the road surface. Each time the hammer head 42 moves up and down, the distance between the T-shaped plate 51 and the positioning plate 55 changes. Furthermore, the distance is measured in real time through the distance sensor 56. When the hammer head 42 descends to strike the pile head 44, the distance sensor 56 detects that the distance of the T-shaped plate 51 has been reduced to the threshold value and emits a feedback signal. Subsequently, the high-voltage generator 34 is activated through the microcontroller. The high-voltage generator 34 transmits the current to the electrode 32 through the high-voltage insulating cable 35, and emits pulsed current to the road surface at the drilling position through the electrode 32, generating electromagnetic force and shock waves inside the rock, which helps to break the rock, assist the pile driver to improve the piling efficiency, and generate cracks in the rock when facing hard strata, reducing the piling difficulty.

[0032] When the hammer head 42 rises, the distance sensor 56 detects that the T-shaped plate 51 is moving away beyond the detection threshold value, and stops the operation of the high-voltage generator 34 through the microcontroller. Therefore, during the reciprocating piling process, pulsed current can be intermittently emitted automatically following the piling frequency. Compared with continuously emitting current, it enables the equipment to have time to dissipate heat and rest, can cause a fatigue effect on the rock formation, and is more likely to further break the rock along these already expanded cracks, thereby improving the rock-breaking efficiency of the rock formation. Intermittently emitting pulsed current can reduce the electromagnetic interference at the construction site and flexibly adjust the emission frequency and intensity according to the actual rock-breaking situation of the rock formation.

[0033] In the buffer part 5, the buffer column 52 moves up and down following the hammer head 42. When descending, the bottom end of the buffer column 52 is longer than the pile frame 41, so it will enter the limit cover 24 first to avoid deviation, causing the buffer column 52 to abut against the shock-absorbing pad 33, and tightening the limit piece 53 through the tension of the tension spring 54, stably pressing the insulating column 31 against the ground. At the same time, the impact vibration generated during piling can be transmitted to the buffer column 52 through the shock-absorbing pad 33 and then to the tension spring 54 for buffering, thereby reducing the damage to the components caused by the vibration, further ensuring the stability of the high-voltage pulse, and avoiding the hidden danger of pulsed current leakage caused by the electrode 32 bouncing up due to vibration. By coordinating with the piling frequency, the use safety of the pulse part 3 is further improved.

[0034] Similarly, in dealing with the soil road surface in this case, the current magnitude can be adjusted by the high-voltage generator 34, so that through intermittent discharge, soil particles can be periodically subjected to attractive and repulsive forces under the action of the electric field. Each time discharge occurs, the charge distribution on the surface of the soil particles changes, and the force between the particles also changes accordingly. After multiple intermittent discharges, the soil structure will become loose and the pores between the particles will increase. Compared with continuous discharge, it is easier to loosen the soil, making the drilling operation more efficient and providing a safer and more efficient guarantee for subsequent pile driving.
