Description
Technical Field
[0001] The present invention relates to the technical field of bridge construction, and particularly to a punching pile machine for quickly breaking hard rock formations and a punching method thereof. Background Art
[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern rapidly developing transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings and accessory structures. The upper structure is also called the bridge span structure and is the main structure for crossing obstacles. The lower structure includes abutments, piers and foundations. The bearings are load-transfer devices provided at the supporting points of the bridge span structure and the piers or abutments. The accessory structures refer to approach slabs, tapered slopes, revetments, and diversion works.
[0003] When the existing punching pile machine is working, it cannot dynamically adjust the lifting height of the pile hammer according to the type of soil layer. Due to the relatively harsh working conditions, water seepage occurs at the bottom of the pile hole, and the water at the bottom will increase. When the pile hammer component falls, when the pile hammer contacts the water or moves in the water, the falling speed of the pile hammer is slowed down due to the resistance of the water body, reducing the punching efficiency of the pile hammer. Moreover, due to the different soil qualities at the bottom of the pile hole, when the pile hammer contacts the soil, it is easy to cause the pile hammer to have a deflection angle due to the difference in soil quality. If it is not adjusted in time, the bottom deflection angle will affect the construction of the later building. In addition, the hard rock formation at the bottom of the pile hole needs to be impacted multiple times, reducing the working efficiency of the punching pile machine. Summary of the Invention
[0004] Based on the technical problems that when the pile hammer of the existing punching pile machine contacts the water or moves in the water, the falling speed of the pile hammer is slowed down due to the resistance of the water body, reducing the punching efficiency of the pile hammer, it is easy to cause the pile hammer to have a deflection angle due to the difference in soil quality, affecting the construction of the later building, and the hard rock formation at the bottom of the pile hole needs to be impacted multiple times, reducing the working efficiency of the punching pile machine, the present invention provides a punching pile machine for quickly breaking hard rock formations and a punching method thereof.
[0005] A punching pile machine for quickly breaking hard rock formations proposed by the present invention includes a frame, and also includes a control terminal, a pile hammer component connected to the gantry of the frame through a steel cable, a monitoring module for monitoring the landing angle of the pile hammer after landing and the number of winding turns of the steel cable, and a deviation correction module for correcting the angle of the pile hammer with an angular deviation.

[0013] Preferably, two communication ports that are vertically symmetrical are provided on the other surface of the air storage chamber, and one-way solenoid valves are installed on the inner walls of both communication ports.

[0014] Through the above technical solution, the communication situation of the communication port can be controlled by the one-way solenoid valve, so as to complete the inhalation and extrusion of air. When the hammer body contacts the water body, a large number of bubbles are generated through the air outlet of the air outlet, thereby reducing the resistance between the hammer body and the water body.
[0015] Preferably, a contact block that contacts the outer surface of the steel cable is fixedly connected to the end of the telescopic head of the contact displacement sensor, and a ball for guiding the steel cable is provided on one side surface of the contact block.

[0024] Through the above technical solution, the position of the steel cable can be controlled by the cooperation of the first guiding gear and the meshing groove and the cooperation of the second guiding gear and the guiding rack. The steel cable is sequentially passed through the detecting device, the sliding main sleeve and the connecting sleeve, so that the movement of the sliding sleeve drives the steel cable to move, and the steel cable will not be affected during the rotation of the sliding main sleeve.
[0025] Preferably, a punching method for a punching pile machine for quickly breaking hard rock formations: The punching method is as follows: Step 1: When breaking the hard rock formation, control the steel cable winding mechanism to operate, control the winding turns of the steel cable winding mechanism through the angle sensor, and then control the retracting and releasing length of the steel cable and the lifting height of the pile hammer. Break the hard rock formation by the falling of the pile hammer component. Record the length of the steel cable for the first punching as L1. After lifting the hammer, perform secondary punching, and record the length of the steel cable at this time as L2. The secondary punching amount is L2 - L1, and the depth of this punching is obtained. Compare the database through the control terminal. If the punching amount is less than the set value, increase the lifting height of the pile hammer;
[0026] Step 2: During the falling process of the pile hammer component, the air is guided by the diversion groove and the diversion vane. When the pile hammer component contacts the water, the one-way solenoid valve in the communication port communicating with the diversion cavity opens, and the three first hydraulic cylinders simultaneously push the sealing plate to make the air in the air storage cavity flow from the diversion cavity to the air outlet, thereby generating many small bubbles on the outer side of the hammer body, and then reducing the resistance of the water body to the hammer body;
[0027] Step 3: After the pile hammer contacts the bottom of the pile hole, if the bottom soil layer is composed of multiple types, the pile hammer will be skewed after contacting the soil layer. The skew of the pile hammer will drive the steel cable to generate an angular offset at the gantry of the frame. The offset of the steel cable will squeeze the contact block of the contact type displacement sensor in the offset direction. The contact type displacement sensor transmits the offset distance Q1 to the control terminal, and then controls the correction device to correct the offset amount of the steel cable through the control terminal;
[0028] Step 4: During correction, the control terminal calculates the required movement amount Q in the X direction through coordinates X and the required movement amount Q in the Y direction Y, the command issued controls the second hydraulic cylinder to drive the correction block to move, and at the same time, the servo motor drives the driving handle to rotate. During the rotation of the driving handle, the sliding main sleeve slides in the sliding groove of the driving handle, and controls the first guide gear to rotate in coordination with the meshing groove on the correction block, thereby adjusting the front, back, left, and right positions of the steel cable to adjust Q X and Q Y After the distance is reached, the contact displacement sensor will not be squeezed by the steel cable, and the deflection angle of the steel cable will be corrected.
[0029] The beneficial effects of the present invention are:
[0030] 1. By setting up a detection device, since the steel cable passes through the inner ring of the mounting ring and is located in the middle of multiple contact blocks, after the steel cable is offset, the telescopic head at the front end of the contact displacement sensor on the offset side will be squeezed, so that the contact displacement sensor detects the offset distance of the steel cable and transmits the offset distance back to the control terminal, corrects the offset distance, and makes the bottom surface of the pile hole flat, thereby solving the problem that the slope of the bottom affects the stability of the building after the construction is completed.
[0031] 2. By setting up a correction device, after the angle of the steel cable is offset, the correction block can be driven to move by the second hydraulic cylinder, and the servo motor drives the sliding main sleeve to move through the driving handle, thereby correcting the position of the steel cable.
[0032] 3. By setting up the pile hammer component, when it is not in contact with the water body, the air is guided by the guide groove and the guide blades, and when it is in contact with the water body, the guide groove and the guide blades guide the water body, and a large number of bubbles are generated through the continuous air outlet, which reduces the resistance between the hammer body and the water, so that the hammer body can better break the pile hole.

Detailed implementation manners
[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0045] Refer to Figures 1-10, a punching pile driver for quickly breaking hard rock formations and its punching method, including a frame 1, further including a control terminal, a pile hammer component connected to the gantry of the frame 1 through a steel cable 2, a monitoring module for monitoring the landing angle of the pile hammer after landing and the number of winding turns of the steel cable 2, and a deviation correction module for correcting the angle of the pile hammer with an angular deviation. The monitoring module includes an angle sensor 3 installed on the steel cable 2 winding mechanism on the upper surface of the frame 1 for monitoring the number of winding turns of the steel cable 2, and a detection device installed at the gantry of the frame 1 for monitoring the landing angle of the pile hammer. A correction device for correcting the pile hammer with a deflection angle is installed on one side surface of the gantry of the frame 1 below the monitoring component;
[0046] As Figures 1-3 and Figure 9 shown, among which, the pile hammer component includes a hammer body 4. In order to reduce the resistance between the hammer body 4 and air or water during the falling process, a diversion blade 41 for guiding water flow to reduce the falling resistance of the hammer body 4 in water is connected to the circumferential side surface of the hammer body 4. Further, in order to prevent the hammer body 4 from affecting the normal use of the steel cable 2 when it rotates under the guidance of air flow or water flow, the top of the hammer body 4 is connected to the end of the steel cable 2 through a face bearing. Further, in order to further guide the water flow between the hammer body 4 and the water flow, the outer surface of the lower end of the hammer body 4 is in the shape of a frustum of a cone and a diversion groove 42 for guiding water flow is provided on the circumferential side surface, so that the hammer body 4 can rotate under the guidance of air flow in the air or water flow in water, so that the rotation of the hammer body 4 will not interfere with the normal use of the steel cable 2, and the water flow is guided through the diversion groove 42 to reduce the water resistance.
[0047] Further, in order to reduce the water resistance when moving in deeper water, an air storage cavity 43 is provided in the inner wall of the hammer body 4, and an installation cavity is provided on one side inner wall of the air storage cavity 43. The inner walls of the three installation cavities are all fixedly installed with a first hydraulic cylinder 44. Further, a sealing plate 45 for pumping air in or out is fixedly connected to the end of the hydraulic rod of the first hydraulic cylinder 44, so that a small amount of air can be stored in the hammer body 4. By controlling the sealing plate 45 through the first hydraulic cylinder 44, the air in the air storage cavity 43 can be pumped in or out. Further, in order to store air in the air storage cavity 43 or extrude the air in the air storage cavity 43, two communication ports 46 that are symmetrically arranged up and down are provided on the other side surface of the air storage cavity 43, and one-way solenoid valves 47 are installed on the inner walls of the two communication ports 46, so that one end of one of the communication ports 46 penetrates to the top surface of the hammer body 4.
[0048] In order to discharge the air to the surrounding of the hammer body 4, a diverter chamber 48 is opened on the inner wall of the lower end of the hammer body 4, so that the inner wall of another connecting port 46 is connected with the inner wall of one side of the diverter chamber 48, and the inner wall of the diverter chamber 48 is opened with an outlet port 49 which is connected with the inner wall of the guide groove 42. The connection of the connecting port 46 can be controlled by the one-way solenoid valve 47, thereby completing the suction and extrusion of air, and when the hammer body 4 contacts with the water body, a large number of bubbles are generated through the exhaust of the outlet port 49, thereby reducing the resistance between the hammer body 4 and the water body.
[0049] By setting up the pile hammer component, when not in contact with the water body, the air is guided by the guide groove 42 and the guide blade 41, and when in contact with the water body, the guide groove 42 and the guide blade 41 guide the water body, and a large number of bubbles are generated through the continuous outlet 49, thereby reducing the resistance between the hammer body 4 and the water, so that the hammer body 4 can better break the pile hole.
[0050] like Figures 1-3 , Figure 7 and Figure 10 As shown, the detection device includes a mounting ring 5 fixed on the lower surface of the gantry of the frame 1. In order to install the contact displacement sensor 52, a first mounting opening 51 distributed in a ring array is opened on the inner surface of the mounting ring 5, and a contact displacement sensor 52 is fixedly installed on the inner wall of the first mounting opening 51. The contact displacement sensor 52 is a grating type. Furthermore, in order to monitor the offset distance of the steel cable 2 through the contact displacement sensor 52, a contact block 53 in contact with the outer surface of the steel cable 2 is fixedly connected to the end of the telescopic head of the contact displacement sensor 52. In order to reduce the friction between the steel cable 2 and the contact block 53, a ball for guiding the steel cable 2 is arranged on one side surface of the contact block 53. The position of the steel cable 2 can be monitored in real time through the contact between the steel cable 2 and the contact block 53, and the friction between the steel cable 2 and the contact block 53 can be reduced by the ball.
[0051] By setting up the detection device, since the steel cable 2 passes through the inner circle of the mounting ring 5 and is located in the middle of the multiple contact blocks 53, after the steel cable 2 is offset, the telescopic head at the front end of the contact displacement sensor 52 on the offset side will be squeezed, so that the contact displacement sensor 52 detects the offset distance of the steel cable 2 and transmits the offset distance back to the control terminal, and corrects the offset distance, so that the bottom surface of the pile hole is flat, thereby solving the problem that the slope of the bottom affects the stability of the building after the construction is completed.
[0052] like Figures 1-7As shown in the figure, the correction device includes a mounting seat 6 fixed to one side of the gantry of the frame 1 and a correction block 61 on one side of the mounting seat 6. In order to drive the driving handle 64, a servo motor 62 is fixedly installed on the upper surface of the mounting seat 6 through two symmetrically arranged supporting seats on the left and right, and a driving handle 64 with a sliding groove 63 opened on its upper surface is fixedly sleeved on the outer surface of the main shaft of the servo motor 62. Further, in order to adjust the distance between the mounting seat 6 and the correction block 61, a support port 65, a support sliding groove 66 and a second mounting port 67 are opened on one end surface of the mounting seat 6, and a second hydraulic cylinder 68 is fixedly installed on the inner wall of the second mounting port 67. The end of the hydraulic rod of the second hydraulic cylinder 68 is fixedly connected to one end surface of the correction block 61, so that the second hydraulic cylinder 68 can be installed through the second mounting port 67, and the position of the correction block 61 can be adjusted through the second hydraulic cylinder 68.
[0053] Further, in order to stably support between the mounting seat 6 and the correction block 61, two symmetrically arranged support shafts 69 that are movably sleeved with the inner wall of the support port 65 are fixedly connected to one end surface of the correction block 61, and a support slider 610 that is slidably inserted into the inner wall of the support sliding groove 66 is fixedly connected to one end surface of the correction block 61. The correction block 61 can be supported through the cooperation of the support shaft 69 and the support port 65, and the correction block 61 can be guided and supported through the cooperation of the support slider 610 and the support sliding groove 66.
[0054] Further, in order to change the position of the steel cable 2 by rotating the driving handle 64, an engagement groove 611 is formed on the upper side surface of the correction block 61. In order to guide the connecting sleeve 617, a guiding groove 612 penetrating through the lower surface of the correction block 61 is formed on the upper surface of the correction block 61. In order to install the guiding rack 614, an installation groove 613 is formed on one inner wall of the middle part of the guiding groove 612, and the guiding rack 614 is fixedly connected to the inner wall of the installation groove 613, so that the guiding rack 614 can be installed in the middle of the installation groove 613. In order to drive the sliding main sleeve 615 to move by rotating the driving handle 64, the sliding main sleeve 615 is slidably sleeved in the sliding groove 63 of the driving handle 64, and a first guiding gear 616 engaged with the engagement groove 611 is fixedly connected to the lower end surface of the sliding main sleeve 615. Further, in order to prevent the sliding main sleeve 615 from moving up and down, a connecting sleeve 617 slidably sleeved with the inner wall of the guiding groove 612 is fixedly connected to the lower surface of the first guiding gear 616, and a second guiding gear 618 engaged with the guiding rack 614 for transmission is fixedly connected to the outer surface of the connecting sleeve 617. The steel cable 2 passes through the detection device, the sliding main sleeve 615 and the connecting sleeve 617 in sequence. The position of the steel cable 2 can be controlled through the cooperation between the first guiding gear 616 and the engagement groove 611 and the cooperation between the second guiding gear 618 and the guiding rack 614. The steel cable 2 passes through the detection device, the sliding main sleeve 615 and the connecting sleeve 617 in sequence to drive the steel cable 2 to move when the sliding main sleeve 615 moves, and the steel cable 2 will not be affected during the rotation of the sliding main sleeve 615.
[0055] By providing the correction device, after the angle of the steel cable 2 is offset, the correction block 61 can be driven to move by the second hydraulic cylinder 68, and the servo motor 62 drives the sliding main sleeve 615 to move through the driving handle 64, so as to achieve the effect of correcting the position of the steel cable 2.
[0056] Working principle: Step 1: When breaking the hard rock formation, control the operation of the steel cable 2 winding mechanism. Control the winding turns of the steel cable 2 winding mechanism through the angle sensor 3, so as to control the retracting and releasing length of the steel cable 2 and the lifting height of the pile hammer. Break the hard rock formation by the falling of the pile hammer component. Record the length of the steel cable 2 for the first punching as L1. After lifting the hammer, perform secondary punching, and record the length of the steel cable 2 at this time as L2. The secondary punching amount is L2 - L1, and the depth of this punching is obtained. Compare with the database through the control terminal. If the punching amount is less than the set value, increase the lifting height of the pile hammer;
[0057] Step 2: During the falling process of the pile hammer component, the diversion groove 42 and the diversion vane 41 divert the air. When the pile hammer component contacts the water, the one-way solenoid valve 47 in the communication port 46 communicating with the shunt cavity 48 opens, and the three first hydraulic cylinders 44 simultaneously push the sealing plate 45, causing the air in the air storage cavity 43 to flow from the shunt cavity 48 towards the air outlet 49, thereby generating many small bubbles on the outside of the hammer body 4, and then reducing the resistance of the water body to the hammer body 4;
[0058] Step 3: After the pile hammer contacts the bottom of the pile hole, if the bottom soil layer is composed of multiple types, the pile hammer will be skewed after contacting the soil layer. The skew of the pile hammer will drive the steel cable 2 to generate an angular offset at the gantry of the frame 1. The offset of the steel cable 2 will squeeze the contact block 53 of the contact displacement sensor 52 in the offset direction. The contact displacement sensor 52 transmits the offset distance Q1 to the control terminal, and then the control terminal controls the correction device to correct the offset of the steel cable 2;
[0059] Step 4: During correction, the control terminal calculates the required movement amount Q in the X direction through coordinates X and the required movement amount Q in the Y direction Y , and issues an instruction to control the second hydraulic cylinder 68 to drive the correction block 61 to move. At the same time, the servo motor 62 drives the drive handle 64 to rotate. During the rotation of the drive handle 64, the sliding main sleeve 615 slides in the sliding groove 63 of the drive handle 64, and controls the first guide gear 616 to cooperate with the meshing groove 611 on the correction block 61 to rotate, thereby adjusting the front, back, left, and right positions of the steel cable 2. After adjusting the distances of Q X and Q Y , the contact displacement sensor 52 will not be squeezed by the steel cable 2, and the deflection angle of the steel cable 2 is thus corrected.
[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.

7. The punching method of a punching pile machine for quickly breaking hard rock formations according to any one of claims 1-6, the punching method is as follows: Step 1, when breaking hard rock formations, control the operation of the steel cable (2) winding mechanism, control the winding turns of the steel cable (2) winding mechanism through the angle sensor (3), and further control the retracting and extending length of the steel cable (2) and the lifting height of the pile hammer. Break the hard rock formation by the falling of the pile hammer component. Record the length of the steel cable (2) for the first punching as L1. After lifting the pile hammer, perform secondary punching, record the length of the steel cable (2) at this time as L2, and the secondary punching amount is L2-L1 to obtain the depth of this punching. Compare the database through the control terminal. If the punching amount is less than the set value, increase the lifting height of the pile hammer; Step 2, during the falling process of the pile hammer component, the air guiding groove (42) and the air guiding blades (41) guide the air. When the pile hammer component contacts with water, the one-way solenoid valve (47) in the communication port (46) communicated with the shunt cavity (48) is opened, and the three first hydraulic cylinders (44) simultaneously push the sealing plate (45) to make the air in the air storage cavity (43) flow from the shunt cavity (48) to the air outlet (49), so as to generate many small bubbles on the outer side of the hammer body (4), thereby reducing the resistance of the water body to the hammer body (4); Step 3. After the pile hammer contacts the bottom of the pile hole, if the soil layer at the bottom consists of multiple types, the pile hammer will be skewed after contacting the soil layer. The skew of the pile hammer will drive the steel cable (2) to generate an angular offset at the gantry of the frame (1). The offset of the steel cable (2) will squeeze the contact block (53) of the contact displacement sensor (52) in the offset direction. The contact displacement sensor (52) transmits the offset distance Q1 to the control terminal, and then the control terminal controls the correction device to correct the offset of the steel cable (2); Step 4: During correction, the control terminal calculates the required movement amount Q in the X direction through coordinates X and the required movement amount Q in the Y direction Y , and issues an instruction to control the second hydraulic cylinder (68) to drive the correction block (61) to move. At the same time, the servo motor (62) drives the drive handle (64) to rotate. During the rotation of the drive handle (64), the sliding main sleeve (615) slides in the sliding groove (63) of the drive handle (64), and controls the first guiding gear (616) to cooperate with the meshing groove (611) on the correction block (61) to rotate, thereby adjusting the front, back, left, and right positions of the steel cable (2) and adjusting Q X and Q Y . After adjusting the distance of, the contact displacement sensor (52) will not be squeezed by the steel cable (2), and the deflection angle of the steel cable (2) is completed.
