[0016] (III) Beneficial effects Compared with the prior art, the present invention provides a pulse coordinated adaptive control type road and bridge geological efficient piling device, which has the following beneficial effects: 1. The pulse coordinated adaptive control type road and bridge geological efficient piling device adopts the piling frequency combined with the intermittent emission of pulse current to improve the piling efficiency. When facing hard formations such as rock formations, the pulse current automatically emitted intermittently by the pulse part can generate electromagnetic force and shock waves inside the rock, causing cracks in the rock, effectively assisting the pile driver to reduce the difficulty of piling and improve the efficiency of piling.

[0017] 2. This pulse coordinated adaptive control type road and bridge geological efficient piling device, when applied to soil pavement, uses a high-voltage generator to adjust the current size for intermittent discharge, which can make the soil particles periodically stressed under the action of the electric field, change the charge distribution and the force between the particles, and make the soil structure loose and the pores increase after multiple actions.

[0018] 3. The pulse coordinated adaptive control type road and bridge geological efficient piling device adopts the working mode of intermittent pulse current emission to protect equipment and improve stability.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-7 The present invention provides a technical solution: a pulse coordinated adaptive control type road and bridge geological efficient piling device, including a vertical guide rail 1, the vertical guide rail 1 is one of the components of the pile driver body in the prior art, and no further details are given in this case. The mounting part 2 of this case is mounted on the side wall of the vertical guide rail 1, and is used to install a ground pulse tool. The pulse part 3 of this case is mounted on the mounting part 2, and is used to automatically and intermittently emit pulse current to break rock formations.

The buffer part 5 of this case is mounted on the piling part 4, and is used to buffer the piling vibration force received by the pulse part 3.

[0026] In the present invention, in order to more easily adapt to the pulse tools related to this case, the mounting portion 2 of this case includes two mounting feet 21, both mounting feet 21 are mounted on one side of the vertical guide rail 1, the ends of the two mounting feet 21 are fixedly connected with a U-shaped frame 22, and two ear ends of the U-shaped frame 22 are provided with two sockets, and the top surface of one ear end of the U-shaped frame 22 is fixedly connected with a support rod 23, and there are six support rods 23 in total, and every three support rods 23 are respectively arranged around the outside of a socket, and the tops of every three adjacent support rods 23 are fixedly connected with a limiting cover 24, and the side wall of the U-shaped frame 22 is fixedly connected with a threading frame 25, and the threading frame 25 is used to thread the cable to avoid entanglement, and a frame 26 is fixedly connected between the two mounting feet 21. There are two mounting parts 2, and the two mounting feet 21 of the other mounting part 2 are mounted on the other side of the vertical guide rail 1, and the two mounting parts 2 are symmetrically arranged with each other.

[0027] In this embodiment, in order to use the pile driving frequency to call the pulse current in real time to process the road surface, the pulse part 3 of this case includes two insulating columns 31, and the two insulating columns 31 are respectively inserted into the inner walls of the two jacks aligned with each other between the ear ends of the U-shaped frame 22 of the mounting part 2 on one side. The bottoms of the two insulating columns 31 are provided with rod grooves, and the inner walls of each rod groove are fixedly connected with electrodes 32. The tops of the two insulating columns 31 are fixedly connected with shock-absorbing pads 33. A high-voltage generator 34 is installed on the frame 26, and a TP3020 high-voltage pulse power supply is used to connect to the city power during road and bridge construction. A high-voltage insulated cable 35 is connected between the high-voltage generator 34 and the two insulating columns 31. The two high-voltage insulated cables 35 pass through the threading frame 25 and are electrically connected to the two electrodes 32 respectively. There are two pulse parts 3, and another pulse part 3 is installed on another mounting part 2. The two pulse parts 3 are symmetrically arranged with each other.

[0028] It is worth noting that the piling part 4 in this case includes a pile frame 41, which is installed on the mover end of the vertical guide rail 1, and the inner wall of the pile frame 41 is slidably connected with a hammer head 42, and a lifting cylinder 43 is installed in the pile frame 41, and the telescopic end of the lifting cylinder 43 is fixedly connected to the hammer head 42, and 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 with the hammer head 42.

[0029] In order to further improve the stability and safety of piling, the buffer part 5 in this case includes a T-shaped plate 51, which is fixedly connected to one side of the pile frame 41. Two buffer columns 52 are slidably penetrated on the T-shaped plate 51. The top ends of the two buffer columns 52 are fixedly connected to limit plates 53. Tension springs 54 are elastically connected between the two limit plates 53 and the T-shaped plate 51. The two tension springs 54 are movably mounted on the two buffer columns 52 respectively. 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 is worth noting 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 of each insulating column 31 is respectively located between the three support rods 23 adjacent to itself, and the bottom end of each buffer column 52 is a curved surface structure. Each buffer column 52 passes through the corresponding limit cover 24 and abuts against the aligned shock-absorbing pad 33. The support rod 23 and the limit cover 24 can further ensure the stability of the lifting and lowering of the pile frame 41 and improve the work safety. The two high-voltage generators 34 are electrically connected to the microcontroller, and the distance sensor 56 in each buffer part 5 is respectively electrically connected to the microcontroller located on the same side, and each distance sensor 56 is respectively aligned with the T-plate 51 adjacent to itself.

[0031] Working principle: the mover end of the vertical guide rail 1 lifts the pile frame 41 to a high position, and the insulating columns 31 on the U-shaped frames 22 on both sides are perpendicular to the road surface, prompting the electrode 32 to contact the road surface, and the lifting cylinder 43 drives the hammer head 42 to rise and fall back and forth, prompting the hammer head 42 to repeatedly hit the pile head 44, thereby drilling the road surface. Each time the hammer head 42 rises and falls, the distance between the T-plate 51 and the positioning plate 55 changes, and then the distance is measured in real time by the distance sensor 56. When the hammer head 42 descends and hits the pile head 44, the distance sensor 56 detects that the distance of the T-plate 51 is reduced to the threshold and sends a feedback signal, and then activates the high-voltage generator 34 through the microcontroller. The high-voltage generator 34 transmits current to the electrode 32 through the high-voltage insulated cable 35, and sends a pulse 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 and assist the pile driver to improve the efficiency of pile driving. When facing hard formations, cracks are generated in the rock to reduce the difficulty of pile driving.

[0032] When the hammer head 42 rises, the distance sensor 56 detects that the T-plate 51 is away from the detection threshold and stops the high-voltage generator 34 through the microcontroller. Therefore, during the reciprocating pile driving process, the pulse current can be automatically emitted intermittently according to the frequency of the pile driving. Compared with the continuous emission current, it can give the equipment time to dissipate heat and rest, which can cause fatigue effect in the rock formation and make it easier to further break the rock along these already extended cracks, thereby improving the crushing efficiency of the rock formation. The intermittent emission of pulse current can reduce electromagnetic interference at the construction site and flexibly adjust the emission frequency and intensity according to the actual crushing situation of the rock formation.

[0033] The buffer column 52 in the buffer part 5 moves up and down with the hammer head 42. When descending, the bottom end of the buffer column 52 is longer than the pile frame 41, so it will first enter the limit cover 24 to avoid deviation, so that the buffer column 52 abuts the shock-absorbing pad 33, and tightens the limit plate 53 through the tension of the tension spring 54, so that the insulating column 31 is stably pressed 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, avoiding the hidden danger of pulse current leakage caused by the electrode 32 bouncing up due to vibration, and further improving the safety of the pulse part 3 by coordinating with the piling frequency.

[0034] Similarly, when dealing with soil roads, the current size can be adjusted through the high-voltage generator 34, so that through intermittent discharge, the soil particles can be periodically subjected to attraction and repulsion under the action of the electric field. Each time the 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 safer and more efficient protection for subsequent pile driving.
