Detailed implementation manners

[0040] 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 scope of protection specifically claimed by the present invention.

[0041] As used herein, terms such as "parallel", "perpendicular" and the like are not limited to their strict geometric definitions, but include tolerances for machining or human error and inconsistencies.

[0042] As Figure 1-2 As shown, the main structure of the amphibious pile driver of the present invention includes a machine base 200. A pile frame 300 is provided on the machine base 200. A pile hoisting device 400 and a pile driving mechanism 500 are provided on the pile frame 300. A pile guide 600 is also provided 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. During pile driving, the pile driving mechanism 500 continuously does work on the engineering pile 100 to drive the engineering pile 100 into the soil.

[0043] For foundation construction such as docks, seaports, etc., 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 total weight of some pile drivers 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.

[0044] As Figure 3 As shown, 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.

[0045] The main front box bodies 210 are arranged at intervals along the width direction of the machine base. 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. 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.

[0046] As Figure 3-4 As shown, 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. The two A connecting parts 211 and the A connecting component 230 are further connected together by screws. Such a connection method is provided in multiple numbers along the length direction of the machine base. As Figure 5As shown in the figure, a B1 connection part 212 is also welded on the main front box body 210, and a B2 connection part 221 is welded on the main rear box body 220. The B1 connection part 212 and the B2 connection part 221 are connected together by pins, and multiple such connection methods are provided along the height direction of the machine base. As Figure 6 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, and 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.

[0047] 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.

[0048] When performing water construction, a large amount of water can be injected into the front counterweight bin arranged on the main front box body 210 to increase the weight of the rear end of the pile driver and improve stability, which is more convenient than cement counterweight. A rear counterweight bin for adding water for counterweight is arranged on the main rear box body 220, and a large amount of water can be injected into the rear counterweight bin according to requirements to further increase the weight of the rear end of the pile driver and improve stability during water construction.

[0049] 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.

[0050] 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.

[0051] 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. By repeating this cycle, the walking action is completed.

[0052] 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 and walking method of the support legs makes the positioning of the engineering pile 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 for large rivers and the sea.

[0053] As Figure 7-8 shown, a pile guide includes a pile guide body 600. The pile guide body is provided with 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 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.

[0054] As Figure 8 shown, the pile guide body includes two oppositely arranged arc-shaped A mounting members 620 and B mounting members 630. One end of the A and B mounting members is movably installed on the pile frame 300. The other end of the A and B mounting members is in a suspended state. 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.

[0055] On both sides of the pile frame 300, fixed parts 650 are fixedly arranged. One ends of the A and B mounting parts are respectively assembled on the fixed parts 650. There is also a vacant mounting position on the pile frame 300, and a movable part 660 with movable mounting is arranged at the vacant mounting position. The movable part 660 is located between the two fixed parts. A guide pile roller 610 is arranged at the end of the movable part 660 close to the center of the guide pile part.

[0056] The adjusting assembly is composed of an adjusting oil cylinder 670 arranged between the A mounting part 620, the B mounting part 630 and the fixed part 650.

[0057] As Figure 8 shown, the guide pile rollers 610 mounted on the A and B mounting parts are respectively denoted as the A guide pile roller 610a and the B guide pile roller 610b, and the guide pile roller mounted on the movable part is denoted as the C guide pile roller 610c. As Figure 10 shown, the A and B guide pile rollers are respectively mounted on the A and B assembly pipes 68, and A and B mounting pipes 690 are respectively arranged on the A and B mounting parts. The A and B assembly 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 assembly pipes 680. The assembly holes 681 are arranged at intervals on the A and B assembly pipes 680 along the length direction of the A and B assembly 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 guide pile rollers 610 are adjusted; As Figure 7 、 8 and 11 shown, the movable part 660 is movably mounted on the vacant mounting position 661. A roller position adjusting oil cylinder 662 for adjusting the movement of the movable part is arranged at the vacant mounting position 661. The vacant mounting position 661 is mounted on the pile frame 300. Support parts 621 for people to walk are also respectively arranged on the A and B mounting parts, and guardrails 622 are arranged at the edges of the support parts.

[0058] The working method of the guide pile device 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 assembly pipes 680 drive the A guide pile roller 610a and the B guide pile roller 610b to move closer to or away from the center of the guide pile part at the same time to adapt to 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 part 620 and the B mounting part 630 to approach each other, so that the A guide pile roller 610a and the B guide pile roller 610b clamp the engineering pile, drive the movable part 660 to move so that the C guide pile roller 610c clamps the engineering pile. Finally, the engineering pile is positioned and guided through the combined action of the A guide pile roller 610a, the B guide pile roller 610b and the C guide pile roller 610c.

[0059] 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 above 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 for the pile transport ship to 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.

[0060] The pile guide of the present invention has a reliable and simple structure. The pile guide diameter of its pile guiding part is adjustable, so that it can adapt to the positioning and guiding of various engineering piles, and is especially suitable for the positioning and guiding of engineering piles with a larger diameter.

[0061] A pile hoisting device, as Figure 1 、 2 shown in Figures 12 and 13, includes a pile frame 300 arranged on a pile driver. An A pile hoisting unit 401 and a B pile hoisting unit 402 for hoisting both ends of an engineering pile are arranged on the pile frame 300. Pile head tying components and pile tail tying components are tied to both ends of the engineering pile. The A and B pile hoisting units include an A pile hoisting component and a B pile hoisting component that are respectively detachably connected and assembled with the pile head tying component and the pile tail tying component, and A and B pile adjusting components for respectively adjusting the states of the A and B pile hoisting components. The A and B pile adjusting components include an A adjusting rope assembly and a B adjusting rope assembly. 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.

[0062] 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 is 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.

[0063] For example, when lifting the pile, such as Figure 1 , 2As shown in Figures 12 and 13, first, use a pile transportation ship 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 this plane passes through the center line of the engineering pile. Then, use the A2 pile tying component 450b and the B2 pile tying component 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 component 450a or the B1 pile tying component to tie the 2 lifting lugs arranged on the pile tail of the engineering pile. In this embodiment, use the A1 pile tying component 450a to tie the 2 lifting lugs arranged on the pile tail of the engineering pile. Of course, it is also possible to use the B1 pile tying component to tie the other side of the pile tail of the engineering pile at the same time, but it is not necessary. Then, connect the A2 pile lifting component 437b and the B2 pile lifting component 447b to the A2 pile tying component 450b and the B2 pile tying component 460b respectively, and connect the A1 pile lifting component 434a to the A1 pile tying component 450a; at the same time, adjust the A2 pile lifting component 437b, the B2 pile lifting component 447b and the A1 pile lifting component 434a to horizontally lift the engineering pile in balance; and the B1 pile lifting component is used as a backup for lifting the pile tail. After lifting to a certain height, adjust the A1 pile lifting component 434a to lower so that the engineering pile 100 gradually flips from the horizontal state to the vertical state. After flipping to the vertical state, separate the A1 pile tying component 450a from the A1 pile lifting component 434a, and continue to adjust the A2 pile lifting component 437b and the B2 pile lifting component 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 component 450b from the A2 pile lifting component 437b and the B2 pile tying component 460b from the B2 pile lifting component 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 component 450a arranged on the pile tail, the A2 pile tying component 450b arranged on the pile head, and the B2 pile tying component 460b in sequence. Preferably, the two ends of the A2 steel wire rope on the A2 pile tying component 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 component 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 component 450a are respectively connected to the two lifting lugs on the pile tail.

[0064] As Figure 14As shown, the A1 pile tying component 450a includes an A1 steel wire rope 439a for connecting two lifting lugs on the same side of the same end. It also includes an A1 steel wire rope pulley set 439. The A1 pulley 439b on the A1 steel wire rope pulley set 439 is rotatably installed on the 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 the A1 connecting piece 438. The A1 connecting piece 438 is connected with the A1 pile lifting movable pulley set 434. The A1 pile lifting component 434a also includes the 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 the 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 inserting 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 to be always in an inserted and cooperating state with the pin hole is provided in the round tube 438c. A pulling rope 438e is provided at one end of the cross pin close to the elastic device. When the A1 pile tying component 450a needs to be separated from the A1 pile lifting component 434a, pulling the pulling rope 438e drives 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 pulling rope 438e extends to the ground, and a person pulls the pulling rope 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.

[0065] Similarly, the structures of the A1 pile tying component, A2 pile tying component, B1 pile tying component and B2 pile tying component are the same.

[0066] When hoisting a construction pile, a pile hoisting device of the present invention can hoist the pile head and the pile tail of the construction pile simultaneously, and hoist it in a balanced manner. After hoisting to a certain height, by adjusting the pile head to be stationary and the pile tail to descend, or adjusting the pile tail to be stationary and the pile head to ascend, the construction pile is flipped into a vertical state. Then continue to adjust the pile head to ascend and assemble it with a pile cap provided on a 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.
