[0018] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Reference Figure 1-Figure 3 The present invention provides a prestressed pipe pile limiting and hydraulic hammer pile sinking device, including a hammer main component 1, a plurality of frame assemblies 2 are arranged around the hammer main component 1, and the side wall of the hammer main component 1 is connected to the plurality of frame assemblies 2 through a plurality of connecting arms 3; a movable pulley block 5, a gravity hammer 6, and an earth-taking tube assembly 7 are arranged inside the frame assembly 2, the movable pulley block 5 is fixedly connected to the top of the inner wall of the frame assembly 2, the gravity hammer 6 is fixedly connected to the bottom end of the movable pulley block 5, the earth-taking tube assembly 7 passes through the bottom of the frame assembly 2, a slide rail a is fixedly installed on one side of the frame assembly 2, the connecting arm 3 is slidably sleeved on the slide rail a, the rope traction end of the movable pulley block 5 passes through the outside of the frame assembly 2 to connect to a winch device, the winch device controls the gravity hammer 6 through the movable pulley block 5 to hammer the earth-taking tube assembly 7 into the soil, and the earth-taking tube assembly 7 is used to take out soil around the prestressed pipe pile position to form a de-squeezing hole.

[0020] When assembling the equipment, firstly install several frame assemblies 2 around the prestressed pipe pile position, then hoist the hammer main component 1 to the top of the pile position by a crane, dock the hammer main component 1 with several frame assemblies 2 by several connecting arms 3, and control the gravity hammer 6 by operating the hoisting device to hammer the soil-taking tube assembly 7 into the soil. At this time, the equipment assembly process is completed, and then the prestressed pipe pile is hoisted to the pile position by a crane, and the hammer main component 1 is docked with the top of the pipe pile. The pile is hammered into the soil by the hammer main component 1 to complete the pile sinking. When disassembling the device, the soil-taking tube assembly 7 is taken out of the soil and the soil at that position can be taken out, thereby forming several squeezing holes of the tube device around the prestressed pipe pile. When the remaining pipe piles are sunk to produce a squeezing effect, the flowing soil fills the squeezing holes, thereby eliminating the influence of the flowing soil on the already sunk pipe piles, thereby avoiding the displacement of the pipe piles or the fracture caused by lateral squeezing; The soil taking principle of the soil taking tube assembly 7 is as follows: since the soil taking tube assembly 7 is in a tubular shape, when the soil is hammered into the soil, the soil at that position enters the interior of the soil taking tube assembly 7; when the soil taking tube assembly 7 is pulled out from the ground, the soil inside the soil taking tube assembly 7 is brought out together under the friction force of the inner wall of the soil taking tube assembly 7, thereby achieving the soil taking effect.

[0021] Reference Figure 4 The soil sampling tube assembly 7 is composed of a tube main part 71, a plurality of growth middle tubes 72, and a rigid end head 73. The top of the rigid end head 73 contacts the gravity hammer 6. The growth middle tube 72 includes a main body middle tube 721. The bottom end of the main body middle tube 721 is fixedly connected with a threaded tube 722. The top of the inner wall of the threaded tube 722 is provided with a threaded groove 1 that matches the threaded tube 722. The top of the inner wall of the tube main part 71 is provided with a threaded groove 2 that matches the threaded tube 722. The rigid end head 73 includes a rigid end plate 731 and a threaded tube 732. The threaded tube 732 is fixedly connected to the bottom of the rigid end plate 731. The threaded tube 732 has the same size as the threaded tube 722.

[0022] Through the structural setting of the growing middle tube 72, several growing middle tubes 72 can be assembled along the axis, that is, the threaded tube 1 722 of one growing middle tube 72 is screwed into the threaded groove 1 of the main middle tube 721 of another growing middle tube 72, and the threaded tube 1 722 of the bottommost growing middle tube 72 is screwed into the threaded groove 2 of the tube main part 71. Thus, the soil-extracting tube assembly 7 can be freely adjusted according to the required length. Since the soil-extracting tube assembly 7 is hammered into the soil by the gravity hammer 6, its top end is very easy to be damaged. By setting the rigid end cap 73, the top end of the soil-extracting tube assembly 7 can be protected.

[0023] Reference Figure 5The frame assembly 2 is composed of an end base frame 21, an assembly steel frame 22, and an end top frame 23. The assembly steel frame 22 is fixedly installed on the top of the end base frame 21, and the end top frame 23 is fixedly installed on the top of the assembly steel frame 22. An open groove 211 is opened on one side of the end base frame 21, and a frame inner tube block 212 is fixedly connected to the bottom end of the inner wall of the end base frame 21. The inner cavity diameter of the frame inner tube block 212 matches the diameter of the soil sampling tube assembly 7, and the soil sampling tube assembly 7 passes through the inner cavity of the frame inner tube block 212.

[0024] By providing the assembly steel frame 22 part of the frame assembly 2, since the assembly steel frame 22 can be erected to any height according to needs, the frame assembly 2 can be conveniently adjusted according to the height of the prestressed pipe piles. In addition, by providing the inner tube block 212 of the frame, the soil-extracting tube assembly 7 can be positioned to avoid the soil-extracting tube assembly 7 from tilting when it sinks into the ground. In addition, the inner tube block 212 of the frame can also make the soil-extracting tube assembly 7 and the frame assembly 2 form a whole. When the frame assembly 2 sinks into the soil, it is beneficial to improve the stability of the frame assembly 2. By providing the opening groove 211, it is convenient to place the soil-extracting tube assembly 7 into the interior of the frame assembly 2.

[0025] Reference Figure 6 The bottom end of the tube main part 71 is set as a slope inclined upward toward the inner cavity, and a plurality of wall grooves are provided at the bottom end of the inner wall of the tube main part 71, and a plurality of turning frames 74 are installed in the wall grooves.

[0026] By setting the slope at the bottom end of the main tube part 71, it is connected linearly with the soil-taking tube assembly 7, thereby improving the soil-breaking effect of the soil-taking tube assembly 7. In addition, by setting a plurality of flip frames 74, when the soil-taking tube assembly 7 is pulled out of the soil, the plurality of flip frames 74 are flipped to a horizontal state, thereby forming a barrier effect at the bottom end of the inner cavity of the soil-taking tube assembly 7, thereby preventing the internal soil from falling off during the pulling out process of the soil-taking tube assembly 7.

[0027] Reference Figure 7 The flip frame 74 includes an inner fixed shaft 741, a rotating cylinder 742 is rotatably sleeved on the side wall of the inner fixed shaft 741, a flip knife 743 is fixedly connected to the side wall of the rotating cylinder 742, shaft holes are opened on both sides of the inner wall of the wall groove, two ends of the inner fixed shaft 741 enter the two shaft holes respectively and are fixedly connected to the ends of the shaft holes, two torsion springs 744 are arranged on the side wall of the inner fixed shaft 741, and both sides of the rotating cylinder 742 are transmission connected to the ends of the shaft holes through the two torsion springs 744, and the torsion springs 744 are arranged in the shaft holes.

[0028] When the soil-excavating tube assembly 7 is sunk into the soil and the soil enters the inner cavity of the soil-excavating tube assembly 7, the soil impacts the flip knife 743. Through the connection between the rotary cylinder 742 and the inner fixed shaft 741, the flip knife 743 has a flipping effect and is stuck in the wall groove, preventing the flip frame 74 from causing the soil to enter the soil-excavating tube assembly 7 and causing a barrier. When the soil-excavating tube assembly 7 is in a static state, the soil does not have an upward impact force on the flip knife 743. At this time, under the torsion effect of the torsion spring 744, the flip knife 743 automatically flips and resets and embeds into the soil, forming a barrier for the soil. In addition, by setting the position of the torsion spring 744 in the shaft hole, the soil can be prevented from affecting the torsion spring 744.

[0029] Reference Figure 8 The gravity hammer 6 includes a main hammer body 61, a column hole is provided at the bottom end of the main hammer body 61, a column core 63 is slidably sleeved in the column hole, a special-shaped bottom block 64 is fixedly connected to the bottom end of the column core 63, the top of the column core 63 is fixedly connected to the top of the column hole through a chain 62, the top of the column core 63 is transmission-connected to the top of the column hole through a tension spring, a through hole is provided at the top of the rigid end head 73, a through groove matching the shape of the special-shaped bottom block 64 is provided on the inner wall of the through hole, and an embedding groove matching the shape of the special-shaped bottom block 64 is provided at the bottom of the main hammer body 61.

[0030] In the initial state of the gravity hammer 6, the column core 63 is completely retracted into the column hole under the influence of the tension of the tension spring, and the special-shaped bottom block 64 is embedded in the embedded groove. When the soil extraction tube assembly 7 needs to be pulled out from the soil, the column core 63 is displaced downward by pulling the special-shaped bottom block 64 until the column core 63 passes through the through hole of the rigid end head 73. During the process, the special-shaped bottom block 64 passes through the through groove on the inner wall of the through hole, and then the column core 63 is rotated to make the special-shaped bottom block 64 misaligned with the through groove. At this time, a connection is formed between the gravity hammer 6 and the soil extraction tube assembly 7. When the gravity hammer 6 is controlled to rise, the soil extraction tube assembly 7 can be pulled out, and the chain 62 can prevent the column core 63 from being forced to fall out of the column hole.

[0031] Reference Figure 8 The column core 63 includes an upper part and a lower part, the lower part is rotatably sleeved at the bottom end of the upper part, the special-shaped bottom block 64 is fixedly connected at the bottom end of the lower part, and the chain 62 is fixedly connected at the top end of the upper part.

[0032] Through the structural setting of the column core 63, the lower part rotates independently when the column core 63 is rotated, which can prevent the rotation of the column core 63 from affecting the tension spring.

[0033] Reference Figure 1 , 9A vertical tube frame assembly 4 is arranged at the bottom inner end of the plurality of vertical frame assemblies 2, and the number of the plurality of vertical tube frame assemblies 4 is four. The vertical tube frame assembly 4 includes a main vertical tube 41, and the four sides of the main vertical tube 41 are fixedly connected to the side walls of the four vertical frame assemblies 2 through four connecting frames respectively. The connecting frames include a hydraulic rod 1 46, an end block 1 42, and an end block 2 44. The two ends of the hydraulic rod 1 46 are fixedly connected with a spherical joint 1 43 and a spherical joint 2 45. The ends of the end blocks 1 42 and 2 44 are provided with hemispherical recesses. The spherical joint 1 43 is movably sleeved in the hemispherical recess of the end block 1 42, and the spherical joint 2 45 is movably sleeved in the hemispherical recess of the end block 2 44. The hydraulic rod 1 46 has an initial inclination, and the height of one end of the hydraulic rod 1 46 connected to the spherical joint 1 43 is higher than the height of the other end.

[0034] By setting up the vertical tube frame assembly 4, the axis positioning effect of the predetermined force pipe pile can be achieved. When the pipe pile is placed at the pile position, the pipe pile passes through the inner cavity of the main vertical tube 41. At this time, the axis of the main vertical tube 41 is aligned with the axis of the pipe pile, thereby avoiding the angle deviation of the pipe pile during pile sinking. The horizontality of the main vertical tube 41 can be adjusted by the structural setting of the connecting frame. The adjustment process is controlled by extending the hydraulic rod 46 of the connecting frame on one side of the main vertical tube 41 and contracting the hydraulic rod 46 of the connecting frame on the other side of the main vertical tube 41. At this time, one side of the main vertical tube 41 is subjected to an oblique upward thrust, while the other side is subjected to an oblique downward pulling force. At this time, the angle of the main vertical tube 41 can be changed. During this process, the spherical joints 43 of the other two connecting frames will rotate in the hemispherical recesses of the end block 42. Therefore, the horizontality of the main vertical tube 41 can be adjusted by the cooperation of the four connecting frames.

[0035] Reference Fig.10 A leveling component 47 is fixedly installed on the side wall of the main body cylinder 41, and the leveling component 47 includes a liquid storage tank 471. A fixing plate 472 is fixedly connected to the top of the liquid storage tank 471. A plurality of laser ranging sensors 473 are arranged on the top of the fixing plate 472. The detection end of the laser ranging sensor 473 passes through the interior of the liquid storage tank 471. A protective cover 474 is fixedly connected to the top of the fixing plate 472. Liquid is stored in the liquid storage tank 471.

[0036] The horizontality can be detected by the leveling component 47. When the leveling component 47 is in a tilted state, the liquid inside it will tilt. At this time, the liquid surface distances detected by the plurality of laser distance measuring sensors 473 are different. By setting the plurality of laser distance measuring sensors 473 at different positions, the tilting direction of the leveling component 47 can be known. Since the leveling component 47 is installed on the side wall of the main body cylinder 41, it is convenient to obtain the horizontality data of the main body cylinder 41 through the leveling component 47.

[0037] Reference Figure 11-13The hammer main part 1 includes a fixed shell 11, a pile shell 14 is fixedly connected to the bottom of the fixed shell 11, a hydraulic rod 12 is fixedly installed inside the fixed shell 11, a hammer core 13 is fixedly installed at the output end of the hydraulic rod 12, an inner expansion barrel groove is provided on the inner wall of the pile shell 14, an inner sliding spacer 15 is slidably sleeved in the inner expansion barrel groove, and the inner sliding spacer 15 includes a cylinder shell 151, a rubber inner core 152 is fixedly connected to the inner wall of the cylinder shell 151, a plurality of rigid core columns 153 are provided inside the rubber inner core 152, and a built-in rigid disk 154 is fixedly connected to the side walls of the plurality of rigid core columns 153, and the side walls of the built-in rigid disk 154 pass through the side walls of the rubber inner core 152 and are fixedly connected to the inner wall of the cylinder shell 151.

[0038] When the prestressed pipe pile is sunk by the hammer main component 1, the pipe pile is inserted into the inner cavity of the pile casing 14 from the bottom end of the pile casing 14, and the inner sliding spacer 15 is pushed to slide it to the top, and then the hydraulic rod 12 is operated to reciprocate and extend, so that the hammer core 13 hits the inner sliding spacer 15, and the inner sliding spacer 15 applies force to the pipe pile to make it sink. Compared with the traditional hammer main component 1, the inner sliding spacer 15 is additionally provided to isolate the hammer core 13 from the top of the pipe pile. The material characteristics of the rubber inner core 152 of the inner sliding spacer 15 can protect the top of the prestressed pipe pile to prevent it from being damaged. On the other hand, the noise pollution generated by the impact of the hammer core 13 can be reduced. The structural strength of the rubber inner core 152 is improved through the cooperation between the rigid core column 153 and the built-in rigid disk 154, and the rubber inner core 152 can be prevented from falling off from the inside of the cylindrical shell 151.
