[0002] Prefabricated pipe piles are pile structures that are prefabricated in advance. There are two main types of prefabricated pipe piles: concrete piles and steel piles. Prefabricated pipe piles are driven, pressed or vibrated into the soil using pile driving equipment to increase the bearing capacity of the foundation.

[0003] Among them, the concrete piles of the hollow pipe structure are mostly cylindrical structures. When sinking this type of prefabricated pipe piles, it is necessary to position the pipe body of the prefabricated pipe pile in order to find the exact sinking position of the prefabricated pipe pile. At the same time, during the sinking process of the prefabricated pipe piles, the accuracy of the sinking path of the prefabricated pipe piles must be ensured.

[0004] The traditional positioning method of prefabricated pipe piles is to set up a positioning structure around the prefabricated pipe piles, and use the positioning structure to position and limit the prefabricated pipe piles to a certain position.

This design is used to ensure the positioning balance of the prefabricated pipe pile and the pipe surface corresponding to the positioning part 602, thereby improving the positioning effect of the prefabricated pipe pile.

[0048] The rotation setting angles of multiple support rings on one side of the middle support ring increase successively in the direction away from the middle support ring. This design can drive the remaining sleeves that need to be rotated to the set angle when driving the uppermost and / or lowermost support rings to rotate.

The positioning plates 9 on the inner side of the positioning part 602 cooperate to continuously and accurately position the prefabricated pipe piles.

[0051] The guide parts 601 of several sleeves are located on the same vertical plane. When the opening of the sleeve corresponds to the notch of the upper support frame 1 and the lower support frame 2, the prefabricated pipe pile enters the positioning sleeve assembly 6 through the notch. At this time, the guide parts 601 of several sleeves are combined to form a guide channel. The prefabricated pipe pile can enter the position of the positioning part 602 through the guide channel, which is convenient for rapid positioning of the prefabricated pipe pile. When the prefabricated pipe pile is close to the positioning part 602, at least one support ring is used to drive the corresponding sleeve to rotate the set angle, and several sleeves are The guide part 601 cooperates to push the prefabricated pipe pile to a position coaxial with the positioning part 602. After the support ring drives the sleeve plate to rotate to a set angle, the guide channel formed by the several guide parts 601 is closed. When the guide part 601 rotates, it will push the prefabricated pipe pile to move in the axial direction of the positioning part 602. At the same time, the several guide parts 601 are axially staggered and surrounded in the circumferential direction of the prefabricated pipe pile. The prefabricated pipe pile is positioned to a position coaxial with the positioning part 602 by using the cooperation of the several guide parts 601 and the positioning part 602.

[0052] A support plate 10 is fixedly installed inside the upper support frame 1 and the lower support frame 2. The support plate 10 is distributed on both sides of the inner wall of the notch. A support plate 2 101 is fixedly installed on the surface of the support plate 10. The support plate 2 101 is distributed perpendicular to the support plate 10. A support splint 11 is symmetrically and slidingly installed on the surface of the support plate 2 101 in the upper support frame 1. A support splint 16 is symmetrically and slidingly installed on the surface of the support plate 2 101 in the lower support frame 2. A threaded rod is rotatably installed inside the support plate 2 101. The bottoms of the support splint 11 and the support splint 2 16 are threadedly connected to the corresponding threaded rods inside the support plate 2 101. Motor modules for driving the threaded rods to rotate are installed on the sides of the upper support frame 1 and the lower support frame 2.

[0053] The surfaces of the support splint 11 and the support splint 2 16 are both provided with semicircular grooves. The semicircular grooves in the two support splints 11 and the two support splints 16 are combined to form a circular groove. The circular groove is coaxial with the positioning part 602. When the two support splints 11 and the two support splints 16 respectively form circular grooves, they are used to assist in positioning the prefabricated pipe piles.

[0054] A semicircular support plate 12 is fixedly installed on the upper surface of the support clamp 11, and a plurality of circumferentially distributed clamping block units 13 are arranged on the inner side of the support plate 12. The clamping block units 13 are arc plates, and the clamping block units 13 are radially slidably installed on the inner side of the support plate 12 through sleeve rods 131. A plurality of guide wheels are arranged and distributed on the inner surface of the clamping block units 13, and the guide wheels can roll up and down for the sinking of prefabricated pipe piles.

[0055] A spherical block 132 is fixedly installed at one end of the sleeve rod 131 extending to the outside of the support plate 12, and a semicircular pressure ring 14 is slidably installed on the surface of the support clamp plate 11. A hydraulic rod 15 for driving the pressure ring 14 to move is installed on the upper surface of the support clamp plate 11. When the pressure ring 14 moves in the direction close to the support plate 12, the pressure ring 14 can push all the spherical blocks 132 on the outside of the support plate 12 to move radially, and the inner ring surface of the pressure ring 14 is in tangential contact with the spherical block 132 to drive the spherical block 132 to move radially, so that the sleeve rod 131 is used to generate a radial force on the clamping block unit 13, which then acts on the surface of the prefabricated pipe pile, so as to achieve circumferential uniform pressure on the surface of the prefabricated pipe pile, and at the same time further limit the prefabricated pipe pile, so as to improve the stability of the sinking process of the prefabricated pipe pile.

[0056] Specifically, in this embodiment, the support ring assembly 4 includes a support ring 1 41, two support ring 2s 42, two support ring 3s 43 and two support ring 4s 44. The support ring 1 41 is fixedly connected to the support side plate 3, and the support ring 2 42, the support ring 3 43 and the support ring 44 are distributed away from the support ring 1 41 in sequence, and are rotatably installed on the inner wall of the support side plate 3.

[0057] Specifically, in the present embodiment, the positioning sleeve assembly 6 includes one sleeve 1 61 , two sleeves 2 62 , two sleeves 3 63 and two sleeves 4 64 .

[0058] The set angle at which the support ring 2 42 drives the sleeve plate 2 62 to rotate is 90°, the set angle at which the support ring 3 43 drives the sleeve plate 3 63 to rotate is 180°, and the set angle at which the support ring 4 44 drives the sleeve plate 4 64 to rotate is 270°.

[0059] When the positioning plate 9 on the inner side of the positioning part 602 applies pressure to the prefabricated pipe pile, the forces exerted on the prefabricated pipe pile by the sleeve plate 1 61 and the sleeve plate 3 63 on the horizontal plane are balanced with each other, and no torque is generated; the forces exerted on the prefabricated pipe pile by the sleeve plate 2 62 and the sleeve plate 4 64 on the horizontal plane are balanced with each other, and no torque is generated. Therefore, the surface of the prefabricated pipe pile can be balanced and positioned, thereby ensuring the stability of the prefabricated pipe pile and improving the positioning effect.

[0060] The connecting block 7 is a quarter arc plate, and the connecting guide groove 603 is a 180° semicircular groove. The connecting block 7 between the two positioning parts 602 is fixedly connected to the positioning part 602 close to the side of the sleeve plate 61, and at the same time, one side edge of the connecting block 7 is aligned with one side edge of the positioning part 602 to which it is fixedly connected.

[0061] The curvature design and position of the connecting block 7 and the connecting guide groove 603 can make the two adjacent positioning parts 602 only rotate 90° relative to each other. A gear ring 5 is set on the outer side of the support ring 44, and a motor device is installed on the inner wall of the support side plate 3. The gear at the output end of the motor device is engaged with the gear ring 5 to drive the support ring 44 to rotate, and the support ring 44 drives the sleeve plate 4 64 to rotate. In conjunction with the connection relationship between the connecting block 7 and the positioning part 602, the sleeve plate 3 63 can be driven to rotate to 180° and then stop rotating. The sleeve plate 3 63 can also drive the sleeve plate 2 62 to rotate to 90° and then stop rotating.

[0062] Working principle of prefabricated pipe pile installation and positioning device:

[0063] After determining the sinking position of the prefabricated pipe pile, the positioning device is placed at the sinking position, and the center of the positioning portion 602 of the sleeve plate in the positioning device corresponds to the center of the sinking position, and the positioning device is fixed at this position. At this time, the guide portions 601 of the plurality of sleeve plates in the positioning sleeve plate assembly 6 are all on the same vertical plane, which can be referred to Figure 1-Figure 4 This state is the state before the prefabricated pipe piles are positioned.

[0064] The prefabricated pipe pile is transported from the notch position of the upper support frame 1 to the guide channel composed of several sleeves in the positioning sleeve assembly 6 by means of a lifting device, and the prefabricated pipe pile is transported through the guide channel until the prefabricated pipe pile is close to the positioning portion 602 of the sleeve. At this time, the motor device supporting the inner wall of the side plate 3 is started, and the gear ring 5 is driven by the motor device to rotate, and the gear ring 5 drives the support ring four 44 to rotate, and the support ring four 44 drives the sleeve four 64 to rotate together, and the sleeve four 64 cooperates with its corresponding connecting block 7 to drive the sleeve three 63 to rotate, and the sleeve three 63 cooperates with its corresponding connecting block 7 to drive the sleeve two 62 to rotate, until it rotates to Figure 5 and Figure 6 Status shown.

[0065] When the sleeve plate rotates, the guide part 601 in the sleeve plate will further push the prefabricated pipe pile to move to the position of the positioning part 602. The guide parts 601 in multiple sleeve plates cooperate with the positioning part 602 to finally position the prefabricated pipe pile to a position coaxial with the positioning part 602, thereby realizing the positioning of the prefabricated pipe pile before sinking.

[0066] By utilizing the cooperation between the support rod 8 and the piston rod 81, the positioning plate 9 applies a force to the surface of the prefabricated pipe pile. The positioning plates 9 inside the sleeve plate 1 61, the sleeve plate 2 62, the sleeve plate 3 63 and the sleeve plate 4 64 cooperate with each other to apply forces to different axial sections of the prefabricated pipe pile. At the same time, the applied forces are balanced with each other and no torque is generated. Therefore, the stability of the positioning of the prefabricated pipe pile during the sinking process can be improved, and the accuracy of the sinking path of the prefabricated pipe pile can be ensured.

[0067] Then, the prefabricated pipe pile is assisted in positioning by using the support clamp 11 and the support clamp 2 16, and the position of the support plate 12 is adjusted at the same time, and the pressure ring 14 is driven to move by the hydraulic rod 15, so that the pressure ring 14 applies radial force to the clamping block unit 13 through the spherical block 132 and the sleeve rod 131, and acts on the circumferential surface of the prefabricated pipe pile, so that the surface of the prefabricated pipe pile is evenly stressed, the prefabricated pipe pile is circumferentially limited, and the stability of the sinking process of the prefabricated pipe pile is further improved.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
