Detailed Implementation Manner

[0052] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the protection scope specifically claimed by the present invention.

[0053] As used herein, terms such as "parallel", "perpendicular", etc. are not limited to their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent.

[0054] As Figure 1-2As shown in the figure, the main structure of the amphibious pile driver of the present invention includes a machine base 200, a pile frame 300 is arranged on the machine base 200, a pile hoisting device 400 and a pile driving mechanism 500 are arranged on the pile frame 300, a pile guide 600 is further arranged on the machine base 200, the pile hoisting device 400 is used to assemble the engineering pile 100 with the pile driving mechanism 500, the pile guide 600 is used to guide the assembled engineering pile 100, and during pile driving, the pile driving mechanism 500 continuously does work on the engineering pile 100 to make the engineering pile 100 penetrate into the soil.

[0055] For foundation construction such as docks and seaports, the demand for the size of engineering piles is increasing nowadays. However, the larger the size of the engineering pile, the larger the size of the pile driver. For example, the weight of some pile driver equipment is about 190 tons, the length is about 25 meters, the width is about 18 meters, and the height is about 52 meters. Such a huge pile driver brings great difficulties to transportation. Moreover, traditional pile hoisting devices and pile guides are difficult to meet the requirements of hoisting and guiding large-sized engineering piles.

[0056] As Figure 3 As shown in the figure, to solve the above problems, the machine base of the split-structured pile driving equipment of the present invention includes a machine base 200 for installing a pile driving mechanism. The machine base 200 includes a main floating box, and the main floating box is detachably spliced and assembled by a main front box body 210 and a main rear box body 220. The main front box body 210 and the main rear box body 220 are detachably spliced and arranged along the length direction of the machine base.

[0057] The main front box bodies 210 are arranged at intervals along the width direction of the machine base, and the main rear box bodies 220 are respectively arranged corresponding to each main front box body 210. The main front box bodies 210 are detachably spliced and assembled through an A connecting component 230, the main front box bodies 210 and the main rear box bodies 220 are detachably spliced and assembled through a B connecting component 240, and the main rear box bodies 220 are detachably spliced and assembled through a C connecting component 250. Two main front box bodies 210 and two main rear box bodies 220 are respectively arranged along the width direction of the machine base.

[0058] As Figure 3-4 As shown in the figure, an A connecting part 211 is welded on the main front box body 210, an A connecting component 230 is arranged between the two A connecting parts 211, and the two A connecting parts 211 and the A connecting component 230 are further connected together by screws. This connection method is provided with multiple along the length direction of the machine base. As Figure 5 As shown in the figure, a B1 connecting part 212 is also welded on the main front box body 210, a B2 connecting part 221 is welded on the main rear box body 220, and the B1 connecting part 212 and the B2 connecting part 221 are connected together by pins. This connection method is provided with multiple along the height direction of the machine base. As Figure 6As shown, a C-connection part 222 is also welded on the main rear box body 220. A C-connection assembly 250 is arranged between the two C-connection parts 222. The two C-connection parts 222 and the C-connection assembly 250 are connected together by screws. The above connection method has high connection strength, reliable connection, and can be disassembled.

[0059] A rear counterweight bin for adding water for counterweight is arranged on the main rear box body 220. A front counterweight bin for adding water for counterweight is arranged on the main front box body 210. The front counterweight bin is arranged at the a end of the main front box body 210, and the a end is the end of the main front box body 210 close to the main rear box body 220.

[0060] When performing underwater construction, a large amount of water can be injected into the front counterweight bin arranged on the main front box body 210, increasing the weight at the rear end of the pile driver and improving stability, which is more convenient than using cement for counterweight. A rear counterweight bin for adding water for counterweight is arranged on the main rear box body 220. The rear counterweight bin can inject a large amount of water according to needs, further increasing the weight at the rear end of the pile driver during underwater construction and improving stability.

[0061] As Figure 2-3 shown, auxiliary floating boxes 260 are respectively arranged on the outer sides of the two main front box bodies 210. The two auxiliary floating boxes 260 are installed on the two main front box bodies 210 through a walking assembly frame 270. Support legs 280 are respectively arranged on the auxiliary floating boxes 260 and the main front box bodies 210. The auxiliary floating boxes 260, the main front box bodies 210, the walking assembly frame 270 and the support legs 280 form an alternating walking mechanism. The walking assembly frame 270 includes A brackets 271 arranged in the width direction of the machine base. The A brackets 271 are arranged at intervals along the length direction of the A machine base. The two main front box bodies 210 are slidably assembled with the A brackets 271 in the width direction of the machine base. The two ends of the A brackets 271 are respectively slidably assembled on the B slide rails 272 along the length direction of the A machine base. The support legs 280 are respectively assembled on the auxiliary floating boxes 260 and the main front box bodies 210 in a lifting manner. The two B slide rails 272 are respectively fixedly installed on the two auxiliary floating boxes 260. An A walking adjustment mechanism is arranged between the A brackets 271 and the main front box bodies 210, and a B walking adjustment mechanism is arranged between the B slide rails 272 and the auxiliary floating boxes 260.

[0062] As Figure 1 shown, the pile driving mechanism 500 is arranged at the b end of the main front box body 210, and the b end is the end of the main front box body 210 far from the main rear box body 220.

[0063] When the support legs 280 support the two main front boxes 210 without movement, the support legs 280 on the two auxiliary floating boxes 260 contract. Then, the two auxiliary floating boxes 260 can move forward, backward, left, and right under the adjustment of the A walking adjustment mechanism and the B walking adjustment mechanism. When the support legs 280 support the two auxiliary floating boxes 260 without movement, the support legs 280 on the two main front boxes 210 contract. Then, under the adjustment of the A walking adjustment mechanism and the B walking adjustment mechanism, the two main front boxes 210 can move forward, backward, left, and right. This reciprocating cycle completes the walking action.

[0064] The pile driver of the present invention is large in size and can walk on land and shallow beaches, having the function of being amphibious. Of course, it can be placed on a large pile driving ship for construction. Compared with the traditional sampling and aiming positioning method, the positioning walking method of the support legs makes the positioning of engineering piles more stable. The connection methods between the main front box, the main rear box, and the auxiliary floating box are simple and reliable, and the disassembly and assembly are simple, which is convenient for transportation. It solves the problem that it is difficult for large pile drivers to enter the site for waters such as inland rivers, canals, the Yangtze River, and its tributaries, and meets the construction requirements of large rivers and the sea.

[0065] As Figure 7-8 shown, a pile guide includes a pile guide body 600. The pile guide body has a pile guiding part for the engineering pile to pass through. Guide members for guiding the engineering pile are arranged at intervals around the pile guiding part. The guide members are composed of guide rollers 610 rotatably installed on the pile guide body. The rotation center line of the guide roller 610 is consistent with its length direction. The diameter of the guide roller 610 gradually increases from the middle to both ends. This shape can well guide the cylindrical engineering pile. The direction of the distance between the center of the guide roller 610 and the center of the pile guiding part is denoted as the a direction, and the a direction is perpendicularly arranged with respect to the roller length direction of the guide roller 610. The guide roller 610 is movably installed along the a direction. This adjustable installation method can adapt to engineering piles of different diameters.

[0066] As Figure 8 shown, the pile guide body includes two oppositely arranged arc-shaped A mounting members 620 and B mounting members 630. One ends of the A and B mounting members are movably installed on the pile frame 300. The other ends of the A and B mounting members are in a cantilever shape. The A and B mounting members are connected to an adjustment assembly. The adjustment assembly adjusts the other ends of the A and B mounting members to approach and separate from each other. The guide rollers 610 are respectively rotatably installed on the A and B mounting members. Preferably, one end of the A and B mounting members is rotatably installed on the pile driver and the rotation axis 640 formed by the rotation installation is vertically arranged.

[0067] Fixing members 650 are fixedly arranged on both sides of the pile frame 300. One ends of the A and B mounting members are respectively assembled on the fixing members 650. There is also a vacant mounting position on the pile frame 300, and a movable member 660 is movably mounted at the vacant mounting position. The movable member 660 is located between the two fixing members. A pile guiding roller 610 is arranged at the end of the movable member 660 close to the center of the pile guiding part.

[0068] The adjusting assembly is composed of an adjusting oil cylinder 670 arranged between the A mounting member 620, the B mounting member 630 and the fixing member 650.

[0069] As Figure 8 shown, the pile guiding rollers 610 mounted on the A and B mounting members are respectively denoted as the A pile guiding roller 610a and the B pile guiding roller 610b, and the pile guiding roller mounted on the movable member is denoted as the C pile guiding roller 610c. As Figure 10 shown, the A and B pile guiding rollers are respectively mounted on the A and B assembling pipes 680. A and B mounting pipes 690 are respectively arranged on the A and B mounting members. The A and B assembling pipes 680 are respectively slidably assembled in the A and B mounting pipes 690. Assembly holes 681 are respectively arranged on the pipe bodies of the A and B assembling pipes 680. The assembly holes 681 are arranged at intervals on the A and B assembling pipes 680 along the length direction of the A and B assembling pipes 680. Locking holes 691 are arranged on the A and B mounting pipes 690. By adjusting different assembly holes 681 to correspond to the locking holes 691 and locking them with locking pins 692, the positions of the A and B pile guiding rollers 610 are adjusted; as Figure 7 、 8 and 11 shown, the movable member 660 is movably mounted at the vacant mounting position 661. A roller position adjusting oil cylinder 662 for adjusting the movement of the movable member is arranged at the vacant mounting position 661. The vacant mounting position 661 is mounted on the pile frame 300. Support members 621 for people to walk are also respectively arranged on the A and B mounting members. Guardrails 622 are arranged at the edges of the support members.

[0070] The working method of the pile guide is as follows. First, according to the diameter of the engineering pile, adjust the assembly holes 681 to correspond to the locking holes 691 and lock them with the locking pins 692, so that the A and B assembling pipes 680 drive the A pile guiding roller 610a and the B pile guiding roller 610b to move closer to or away from the center of the pile guiding part at the same time, so as to be suitable for engineering piles of different diameters. When clamping the engineering pile, start the adjusting oil cylinder 670 and the roller position adjusting oil cylinder 662 at the same time, drive the A mounting member 620 and the B mounting member 630 to approach each other, so that the A pile guiding roller 610a and the B pile guiding roller 610b clamp the engineering pile, drive the movable member 660 to move so that the C pile guiding roller 610c clamps the engineering pile. Finally, position and guide the engineering pile through the combined action of the A pile guiding roller 610a, the B pile guiding roller 610b and the C pile guiding roller 610c.

[0071] Preferably, two pile guides are arranged along the length direction of the pile frame, namely an upper pile guide and a lower pile guide, which are convenient for pile splicing. The pile splicing method is as follows: The pile driver travels and positions to the piling position, drives the first section of the engineering pile to a convenient height for pile splicing and welding on the lower pile guide. Both the upper and lower pile guides are in the open state. The pile driver travels backward to leave a space where the pile transport ship can transport into the front of the pile driver. The pile transport ship transports the second section of the pile to the front of the pile driver. The pile driver hoists the engineering pile and assembles it with the pile cap arranged on the piling mechanism. Then, the verticality of the pile body of the engineering pile is adjusted. The upper pile guide holds the engineering pile firmly. The pile driver travels and positions to the piling position, adjusts the angle of the pile body of the engineering pile. The lower pile guide holds the first section of the pile firmly. The pile cap is lowered, and the second section of the engineering pile is lowered onto the first section of the engineering pile for pile splicing. After the pile splicing is completed, the piling mechanism drives the engineering pile to the elevation. During the piling process, the upper and lower pile guides are opened in sequence.

[0072] The pile guide of the present invention has a reliable and simple structure. The pile guiding diameter of its pile guiding part is adjustable, so that it can adapt to the positioning and guiding of various engineering piles, especially suitable for the positioning and guiding of engineering piles with a larger diameter.

[0073] A pile hoisting device, as Figure 1 、 2 shown in Figures 12 and 13, includes a pile frame 300 arranged on the pile driver. An A pile hoisting unit 401 and a B pile hoisting unit 402 for hoisting both ends of the engineering pile are arranged on the pile frame 300.

The A and B adjusting rope assemblies are connected to an A rope winding and unwinding unit and a B rope winding and unwinding unit respectively arranged on the pile driver.

[0074] as Figure 13As shown, the pile head tying pile assembly is provided with an A2 tying pile assembly 450b and a B2 tying pile assembly 460b, and the pile tail tying pile assembly is provided with an A1 tying pile assembly 450a and / or a B1 tying pile assembly. The A2 tying pile assembly 450b and the B2 tying pile assembly 460b are respectively arranged on both sides of the pile head of the engineering pile. The A pile lifting assembly includes an A2 pile lifting assembly 437b, and the B pile lifting assembly includes a B2 pile lifting assembly 447b. It also includes an A1 pile lifting assembly 434a and / or a B1 pile lifting assembly. The A2 pile lifting assembly 437b is detachably assembled and connected to the A2 tying pile assembly 450b, the B2 pile lifting assembly 447b is detachably assembled and connected to the B2 tying pile assembly 460b, and the A1 pile lifting assembly 434a and / or the B1 pile lifting assembly are detachably assembled and connected to the pile tail tying pile assembly. Preferably, the A1 pile lifting assembly 434a is detachably assembled and connected to the A1 tying pile assembly 450a, while the B1 pile lifting assembly and the B1 tying pile assembly are for standby. The A pile adjusting assembly is used to adjust the states of the A1 and A2 pile lifting assemblies, and the B pile adjusting assembly is used to adjust the states of the B1 and B2 pile lifting assemblies.

[0075] For example, when lifting the pile, such as Figure 1 、 2, as shown in FIGS. 12 and 13, first use a pile carrier to horizontally place the engineering piles along the width direction of the pile driver and correspond them to the hoisting device; weld 2 lifting lugs for hoisting the engineering piles on both sides of the pile head of the engineering pile, and weld 2 lifting lugs for hoisting the engineering pile on one side of the pile tail of the engineering pile. Arrange the 6 lifting lugs on the same horizontal plane, and the plane passes through the center line of the engineering pile. Then use the A2 pile tying assembly 450b and the B2 pile tying assembly 460b to tie the lifting lugs arranged on both sides of the pile head of the engineering pile respectively, and use the A1 pile tying assembly 450a or the B1 pile tying assembly to tie the 2 lifting lugs arranged on the pile tail of the engineering pile. In this embodiment, the A1 pile tying assembly 450a is used to tie the 2 lifting lugs arranged on the pile tail of the engineering pile. Of course, the B1 pile tying assembly can also be used to tie the other side of the pile tail of the engineering pile at the same time, but it is not necessary. Then, the A2 pile lifting assembly 437b and the B2 pile lifting assembly 447b are respectively connected to the A2 pile tying assembly 450b and the B2 pile tying assembly 460b, and the A1 pile lifting assembly 434a is connected to the A1 pile tying assembly 450a; at the same time, adjust the A2 pile lifting assembly 437b, the B2 pile lifting assembly 447b and the A1 pile lifting assembly 434a to horizontally lift the engineering pile in balance; and the B1 pile lifting assembly is used as a backup for lifting the pile tail. After lifting to a certain height, adjust the A1 pile lifting assembly 434a to lower so that the engineering pile 100 gradually turns from a horizontal state to a vertical state. After turning to the vertical state, separate the A1 pile tying assembly 450a from the A1 pile lifting assembly 434a, and continue to adjust the A2 pile lifting assembly 437b and the B2 pile lifting assembly 447b to lift up so that the pile head of the engineering pile 100 corresponds to the pile cap arranged on the pile driving mechanism 500 and is assembled. After the assembly is completed, separate the A2 pile tying assembly 450b from the A2 pile lifting assembly 437b and the B2 pile tying assembly 460b from the B2 pile lifting assembly 447b, and then start the pile driving mechanism 500 to drive the pile. During the pile driving process, people stand on the pile guide 600 and remove the A1 pile tying assembly 450a arranged on the pile tail, the A2 pile tying assembly 450b arranged on the pile head, and the B2 pile tying assembly 460b in sequence. Preferably, the two ends of the A2 steel wire rope on the A2 pile tying assembly 450b are respectively connected to the two lifting lugs on one side of the pile head; the two ends of the B2 steel wire rope on the B2 pile tying assembly 460b are respectively connected to the two lifting lugs on the other side of the pile head; the two ends of the A1 steel wire rope on the A1 pile tying assembly 450a are respectively connected to the two lifting lugs on the pile tail.

[0076] As Figure 14As shown in the figure, the A1 pile tying assembly 450a includes an A1 steel wire rope 439a for connecting two lifting lugs on the same side of the same end, and further includes an A1 steel wire rope pulley set 439. An A1 pulley 439b on the A1 steel wire rope pulley set 439 is rotatably installed on an A1 steel wire rope pulley set frame 439c. The A1 pulley 439b is cooperatively connected with the A1 steel wire rope 439a. The A1 steel wire rope pulley set frame 439c is detachably assembled and connected with an A1 connecting piece 438, and the A1 connecting piece 438 is connected with an A1 pile lifting movable pulley set 434. The A1 pile lifting assembly 434a further includes an A1 connecting piece 438, and the A1 connecting piece 438 is connected with the A1 pile lifting movable pulley set 434. Preferably, the A1 steel wire rope pulley set frame 439c is detachably assembled and connected with the A1 connecting piece 438 through an A12 steel wire rope 439d. The A1 connecting piece 438 includes a connecting piece body 438a. The connecting piece body is U-shaped. Pin holes 438b for plugging and cooperating with a cross pin 438d are provided at both ends of the connecting piece body 438a. A round tube 438c is fixedly installed on the outer side of one end of the connecting piece body. The center line of the round tube 438c coincides with the center line of the pin hole 438b. The cross pin 438d is slidably assembled in the round tube 438c. An elastic device for driving the cross pin and the pin hole to be always in a plugged and cooperating state is arranged in the round tube 438c. A pull rope 438e is arranged at one end of the cross pin close to the elastic device. When the A1 pile tying assembly 450a needs to be separated from the A1 pile lifting assembly 434a, the pull rope 438e is pulled to drive the cross pin 438d to move, so that the A12 steel wire rope 439d is disconnected from the A1 connecting piece 438. Preferably, the other end of the pull rope 438e is extended to the ground, and the pull rope is pulled by a person as needed. Preferably, the A1 connecting piece 438 is connected with the A1 pile lifting movable pulley set 434 through a steel wire rope, and this connection method is more flexible.

[0077] Similarly, the structures of the A1 pile tying assembly, the A2 pile tying assembly, the B1 pile tying assembly and the B2 pile tying assembly are the same.

[0078] When the pile hoisting device of the present invention hoists a construction pile, it can hoist the pile head and the pile tail of the construction pile at the same time, and hoist it in a balanced manner. After hoisting to a certain height, by adjusting the pile head to remain stationary and the pile tail to move downward, or adjusting the pile tail to remain stationary and the pile head to move upward, the construction pile is turned into a vertical state. Then continue to adjust the pile head to move upward and assemble it with the pile cap provided on the pile driving mechanism to complete the pile hoisting. The traditional pile hoisting method is to hoist the construction pile only by hoisting the pile head of the construction pile. In this way, the pile tail touches the ground, bringing many safety hazards and being prone to scratching the hull when operating on a ship. The pile hoisting device of the present invention can avoid the above problems and has the advantages of safety and reliability.

[0098] The working method of the pile driver: As Figure 1-20As shown in the figure, the pile driver is moved to the designated position through the A walking adjustment mechanism and the B walking adjustment mechanism. The engineering piles are transported by a pile transport ship and horizontally placed along the width direction of the pile driver and correspond to the hoisting device. Two lifting lugs for hoisting the engineering pile are welded on both sides of the pile head of the engineering pile, and two lifting lugs for hoisting the engineering pile are welded on one side of the pile tail of the engineering pile. The six lifting lugs are arranged on the same horizontal plane, and the plane passes through the center line of the engineering pile. Then, the A2 pile tying assembly 450b and the B2 pile tying assembly 460b are used to tie the lifting lugs arranged on both sides of the pile head of the engineering pile respectively, and the A1 pile tying assembly 450a or the B1 pile tying assembly is used to tie the two lifting lugs arranged on the pile tail of the engineering pile. In this embodiment, the A1 pile tying assembly 450a is used to tie the two lifting lugs arranged on the pile tail of the engineering pile. Then, the A2 pile lifting assembly 437b and the B2 pile lifting assembly 447b are respectively connected to the A2 pile tying assembly 450b and the B2 pile tying assembly 460b, and the A1 pile lifting assembly 434a is connected to the A1 pile tying assembly 450a; at the same time, the A2 pile lifting assembly 437b, the B2 pile lifting assembly 447b and the A1 pile lifting assembly 434a are adjusted to horizontally lift the engineering pile in balance. After lifting to a certain height, the A1 pile lifting assembly 434a is adjusted to descend so that the engineering pile 100 gradually turns from a horizontal state to a vertical state. After turning into a vertical state, the A1 pile tying assembly 450a is separated from the A1 pile lifting assembly 434a. The A2 pile lifting assembly 437b and the B2 pile lifting assembly 447b are continuously adjusted to ascend so that the pile head of the engineering pile 100 corresponds to the pile cap arranged on the pile driving mechanism 500 and is assembled. After the assembly is completed, the A2 pile tying assembly 450b is separated from the A2 pile lifting assembly 437b, and the B2 pile tying assembly 460b is separated from the B2 pile lifting assembly 447b. The pile driving mechanism is adjusted to drive the engineering pile to descend until the engineering pile touches the ground and then stops. Then, the pile guide 600 is started to hold the engineering pile. Finally, the pile driving mechanism is started to perform the operation. During the pile driving process, people stand on the pile guide 600 and remove the A1 pile tying assembly 450a arranged on the pile tail, the A2 pile tying assembly 450b and the B2 pile tying assembly 460b arranged on the pile head in turn.

[0099] As [[ID= and 21 As shown in Fig. -25, an angle-adjustable pile frame structure includes a pile frame 300 body. The lower end of the pile frame 300 body is movably assembled on the base 2 of the pile driver. The pile frame 300 body is connected to a pile frame adjustment mechanism, and the pile frame adjustment mechanism is used to adjust the inclination state of the pile frame body.

[0100] As ​As shown in the figure, the lower end of the pile frame 300 body is movably assembled with the machine base 200 through an assembly hinge assembly 710. The assembly hinge assembly 710 at least includes an A assembly hinge shaft 711. The A assembly hinge shaft 711 is horizontally arranged, and the pile frame adjustment mechanism adjusts the pile frame body to rotate around the A assembly hinge shaft 711 at least. The assembly hinge assembly 710 further includes a B assembly hinge shaft 712. The B assembly hinge shaft 712 is horizontally arranged, and the pile frame adjustment mechanism further adjusts the pile frame 300 body to rotate around the B assembly hinge shaft 712. The A assembly hinge shaft 711 and the B assembly hinge shaft 712 are vertically arranged. One of the A assembly hinge shaft 711 and the B assembly hinge shaft 712 is arranged along the length direction of the machine base, and the other is arranged along the width direction of the machine base.

[0101] The pile frame adjustment mechanism adjusts the pile frame 300 body to swing along the length direction of the machine base or along the width direction of the machine base. This structure enables the pile driver to adjust the inclination angle of the pile frame according to requirements during construction, with flexible use, to meet various construction requirements on the construction site, having the characteristics of multi-function and meeting various construction needs. In addition, the structure of this embodiment is firm and is especially suitable for the angle adjustment of large engineering piles.

[0102] For example, as ​ shown, the pile driving mechanism 500 is slidably installed on the pile frame 300 body. After the engineering pile 100 is assembled with the pile driving mechanism 500, according to the construction requirements, the pile frame adjustment mechanism is used to adjust the inclination state of the pile frame body, and two theodolites are used to measure the angle of the engineering pile. When the engineering pile is adjusted to the angle required for construction, the pile driving mechanism 500 starts to operate to drive the engineering pile into the soil. [[ID=##]]

[0103] As ​ shown, the assembly hinge assembly 710 includes a hinge connection seat 713. The A assembly hinge shaft 711 and the B assembly hinge shaft 712 are assembled on the hinge connection seat 713. The lower end of the pile frame 300 body is hingedly assembled and connected with the hinge connection seat 713 through the A assembly hinge shaft 711, and the hinge connection seat 713 is connected with the machine base 200 through the B assembly hinge shaft 712. The B assembly hinge shaft 712 is composed of B1 and B2 short shafts. The A assembly hinge shaft 711 is located between the B1 and B2 short shafts, and the A assembly hinge shaft 711 is arranged along the length direction of the machine base body.

[0104] As ​ shown, a lifting lug is welded on the machine base 200, and the B assembly hinge shaft 712 is assembled and connected with the lifting lug. In this embodiment of the large pile driver, the weight of each long shaft is very heavy. Therefore, the design of splitting a long shaft into B1 and B2 short shafts can reduce the weight of the shaft itself, facilitate loading and unloading. In addition, the short shaft is easy to process and has high strength, so that it can bear the huge weight of the pile frame body.

[0105] As​ As shown, an A locking component 714 for locking the rotation of the pile frame 300 body around the A assembly hinge shaft 711 is provided between the pile frame 300 body and the articulated connection seat 713. An assembly component is provided at the lower end of the pile frame 300 body. The assembly component includes two assembly plate members 290. The two assembly plate members 290 form an inverted U-shaped assembly mechanism at the lower end of the pile frame body. Assembly mounting holes are provided on the two assembly plate members 290, and the assembly mounting holes are assembled and connected to the shaft ends of the A assembly hinge shaft 711 extending outside the articulated connection seat 713. Reinforcing ribs are provided on the outer plate surfaces of the assembly plate members 290. The A locking component 714 is composed of two groups of locking pin components provided between the assembly plate members 290 and the articulated connection seat 713.

[0106] The two assembly plate members 290 are welded to the lower end of the pile frame 300 body. The connection strength of the two assembly plate members 290 is enhanced by providing reinforcing ribs. The two assembly plate members 290 are assembled and connected to the articulated connection seat 713 through the A assembly hinge shaft 711. When the two A locking components 714 (locking pins) are removed, the pile frame 300 body can swing simultaneously in the width direction and the length direction of the machine base. When the two A locking components 714 (locking pins) are assembled with the articulated connection seat 713, the pile frame 300 body can only swing in the length direction of the machine base.

[0107] As ​ shown, the pile frame adjustment mechanism includes an A pile frame adjustment unit and a B pile frame adjustment unit.

The B1 inclined support adjustment member 731 is located above the B2 inclined support adjustment member 732 and the slope of the B1 inclined support adjustment member 731 is greater than the slope of the B2 inclined support adjustment member 732.

[0109] As ​As shown, preferably, the upper ends of the A2 inclined support adjusting members 722 and the B2 inclined support adjusting members 732 support the middle part of the pile frame body, and the A1 inclined support adjusting members 721 and the B1 inclined support adjusting members 731 support the upper middle part of the pile frame body. This arrangement is reasonable, can effectively support the pile frame body, and has a firm structure. When lifting large engineering piles and driving piles, its structure is very firm and stable.

Two A12 shafts 751 and two B12 shafts 752 are provided on the base. A13 shafts 743 and B13 shafts are provided at the upper ends of the A1 and B1 inclined support adjusting members. The height of the A11 shafts 741 is greater than the height of the B11 shafts 742. The two A11 shafts 741 and the two B11 shafts 742 are respectively arranged along the width direction of the base. The A11 shafts 741 and the A13 shafts 743 are vertically arranged and the A13 shafts 743 are rotationally assembled in the assembly holes opened at the outer ends of the A11 shafts 741. Similarly, the B11 shafts 742 and the B13 shafts are vertically arranged and the B13 shafts are rotationally assembled in the assembly holes opened at the outer ends of the B11 shafts 742. This arrangement enables the upper ends of the respective inclined support adjusting members to swing along the length and width directions of the base.

[0111] The A12 shafts 751 are arranged closer to the pile frame 300 body than the B12 shafts 752. Ball heads are respectively provided on the A12 shafts 751 and the B12 shafts 752.

As ​ shown, ball head members 753 for assembling with the ball heads on the A12 shafts 751 are provided at the lower ends of the A1 and B1 inclined support adjusting members. The ball heads are assembled in the ball head members 753. Similarly, ball head members 753 for assembling with the ball heads on the B12 shafts 752 are provided at the lower ends of the A2 and B2 inclined support adjusting members. This arrangement enables the lower ends of the respective inclined support adjusting members to swing in multiple directions on the base to meet the swinging requirements of the pile frame body at various angles.

When adjusting the lengths of the A1 inclined support adjusting member 721, the A2 inclined support adjusting member 722, the B1 inclined support adjusting member 731, and the B2 inclined support adjusting member 732 simultaneously, the main body of the pile frame 300 can be adjusted to swing along the length direction of the machine base 200. When only adjusting the change in the lengths of the A1 inclined support adjusting member 721 and the A2 inclined support adjusting member 722 while the lengths of the B1 inclined support adjusting member 731 and the B2 inclined support adjusting member 732 remain unchanged, the main body of the pile frame 300 can be adjusted to swing along the width direction of the machine base 200; or when the lengths of the A1 inclined support adjusting member 721 and the A2 inclined support adjusting member 722 remain unchanged and only the lengths of the B1 inclined support adjusting member 731 and the B2 inclined support adjusting member 732 are adjusted, the main body of the pile frame 300 can also be adjusted to swing along the width direction of the machine base 200.

[0114] As ​ shown, the A1 and B1 inclined support adjusting members are arranged in a V shape with the opening of the V pointing obliquely downward, and the A2 and B2 inclined support adjusting members are arranged in a V shape with the opening of the V pointing obliquely downward. This arrangement can achieve adjusting the swing of the main body of the pile frame along the width direction of the machine base. In addition, this arrangement can also enhance the support strength of the main body of the pile frame.

[0115] As ​ and 21As shown in Fig. -25, a method for inclined pile driving is provided. A pile driver assembles a construction pile 100 on a pile driving mechanism 500 provided on the main body of a pile frame 300 at a designated pile driving site.
