During the piling process, if the pile is not vertical or damaged, it needs to be assisted in correction or pulled out and replaced with a new pile. Technical issues

[0003] Since the pile body has a circular hollow structure, a rectangular hollow structure or a diamond hollow structure, the traditional pile pulling component cannot meet the requirements of pile correction or pulling out operations of different shapes during the pile pulling process. Therefore, a pile pulling component is designed here to solve the above problem. Technical Solutions

The opposite side walls of the two conical sleeves are provided with a notch of a half-circular arc structure, and the inner walls of the two notches are parallel to the outer walls of the conical structure at the bottom end of the conical rod. The conical structure of the conical rod is extended into the interior of the pile body to be extracted, and then the two conical sleeves are inserted into the interior of the pile body with the conical rod as the center. The outer walls of the conical sleeves are completely fitted with the inner wall of the pile. As long as the conical rod is lifted upward repeatedly and quickly, the taper of the conical structure of the conical rod expands the two conical sleeves, so that the outer walls of the two conical sleeves can be tightly against the inner wall of the pile. By lifting the conical rod upward, the pile body embedded in the soil can be pulled out by using the two conical sleeves tightly against the inner wall of the pile, so as to assist in correction or pulling out and replacing a new pile body when the pile body is not vertical or damaged.

[0010] Furthermore, the cone sleeve has a top-view structure of a half-rectangular structure.

[0011] Furthermore, the cone sleeve has a top view structure of half a diamond structure.

[0012] According to the different structures of the pile body, cone sleeves of different shapes are selected to ensure that the cone sleeves will not fall along the inside of the pile body after being placed in the pile body, so as to facilitate the use of the cone rod to pull up the pile body.

[0024] The present embodiment provides a pile pulling component, including a cone rod 5 and a cone sleeve 6. The bottom end of the cone rod 5 is a conical structure with a small top and a large bottom. The cone sleeves 6 include two and are symmetrically distributed. An L-shaped handle 7 is vertically fixed on one side of the upper ends of the two cone sleeves 6 away from each other. A notch of a half-conical structure is opened on the opposite side walls of the two cone sleeves 6. As shown in Figure 1, the inner walls of the two notches are parallel to the outer wall of the conical structure at the bottom end of the cone rod 5. The conical structure of the cone rod 5 extends into the interior of the pile to be pulled out, and then the two L-shaped handles are held in hand. The shaped handle 7 inserts the two cone sleeves 6 into the pile body with the cone rod 5 as the center. The outer wall of the cone sleeve 6 is completely in contact with the inner wall of the pile. As long as the cone rod 5 is lifted upward repeatedly and quickly, the taper of the conical structure of the cone rod 5 will expand the two cone sleeves 6, so that the outer walls of the two cone sleeves 6 can be tightly against the inner wall of the pile. By lifting the cone rod 5 upward, the pile body embedded in the soil can be pulled out by using the two cone sleeves 6 tightly against the inner wall of the pile, so as to assist in correction or pull out and replace the new pile body when the pile body is not vertical or damaged. Modes for Carrying Out the Invention

[0025] The invention also adopts two cone sleeves 6 and a cone rod 5 to form a pile puller against the inner wall of the pile body. The installation is quick and easy, the operation is easy and convenient when in use, and the operation and disassembly are simple when not in use, which does not affect the technician's sight line of the construction positioning. Since the pile body shape in the prior art has a circular hollow structure, a rectangular hollow structure or a diamond hollow structure, the traditional pile pulling component cannot meet the requirements of pile correction or extraction operation of pile bodies of different shapes during the pile pulling process. Therefore, the top view structure of the cone sleeve 6 can be set to a half cylindrical structure, as shown in Figures 5 and 6. The two cone sleeves 6 are put together to form a cylindrical structure, which is suitable for the pile pulling operation of a circular structure. The top view structure of the cone sleeve 6 can also be set to a half rectangular structure, as shown in Figures 3 and 4. The half rectangular structure can be separated from the diagonal corner of the rectangular structure or from the middle position of the rectangular structure. As long as the outer wall of the cone sleeve 6 fits the inner wall of the pile body of the rectangular structure, the pile pulling operation of the rectangular structure can be satisfied.

[0026] Of course, for the pile body with zero line structure, the top view structure of the cone sleeve 6 can be a half diamond structure, and the outer wall of the cone sleeve 6 can fit with the inner wall of the diamond structure pile body to meet the requirements of the diamond structure pile body pulling operation.

[0027] It also includes a lifting plate 1 and a toggling ear plate 2. The upper end of the lifting plate 1 is connected to the bottom of the pile pulling elevator, the bottom end of the lifting plate 1 is hinged to the middle position of the toggling ear plate 2, and one end of the toggling ear plate 2 is hinged to the end of the impact hammer installed on one side of the bottom of the pile pulling elevator. The toggling ear plate 2 can swing up and down around the hinge position.

[0028] The other end of the toggle ear plate 2 is rotatably connected to a U-shaped hinged frame 1. Both ends of the U-shaped hinged frame 1 are transversely provided with a coaxially distributed through hole 1. A pin shaft 1 is threadedly connected between the two through holes 1. A closed space is formed between the outer wall of the pin shaft 1 and the inner wall of the U-shaped hinged frame 1. A U-shaped hinged frame 2 3 is sleeved on the outer wall of the pin shaft 1. Both ends of the U-shaped hinged frame 2 3 are transversely provided with a coaxially distributed through hole 2. A pin shaft 2 4 is threadedly connected between the two through holes 2. The outer wall of the pin shaft 2 4 and the U-shaped hinged frame A closed space is formed between the inner walls of the second and third parts, and a lifting hole is provided on the upper end of the tapered rod 5 for slidingly sleeved with the outer wall of the pin shaft 2, as shown in Figures 1 and 7. During use, the hydraulic hammer is operated to cause the toggle ear plate 2 to swing up and down with a small amplitude and rapid speed around the bottom end of the lifting plate 1, and the toggle ear plate 2 moves downward while the other end lifts the tapered rod 5 upward. The taper of the tapered rod 5 is used to expand the two tapered sleeves 6 that are close together. The outer walls of the two tapered sleeves 6 are stuck on the inner wall of the pile body, and the pile body is pulled out with the help of the power of the impact hammer. Industrial Applicability

[0029] A downwardly protruding block is provided on the horizontal part of the L-shaped handle 7 near the bending position of the L-shaped structure, and a clamping opening on the side wall of the pile body is formed between the block and the vertical part of the L-shaped handle 7. The purpose of providing the clamping opening is to ensure that the cone sleeve 6 will not fall along the inside of the pile body after being placed in the pile body, thereby facilitating the cooperation with the cone rod 5 to pull up the pile body.

[0030] In addition, the outer wall of the vertical part of the L-shaped handle 7 is inclined upward toward the side close to the protrusion. The purpose of this setting is to reduce the width of the clamping space in the clamping mouth. After the clamping mouth is clamped on the outer wall of the pile body, the L-shaped handle 7 can be hit with a hammer to force the clamping mouth to be forced to be clamped on the pile body wall, preventing shaking from causing the cone sleeve 6 to be dislocated or even falling off.

[0031] Of course, in addition to the method of using two cone sleeves 6 to cooperate with the cone rod 5 to press against the inner wall of the pile body to form a pile puller to extract the pile body, a hanging rod 8 can also be fixed vertically at the end of the L-shaped handle 7, and a longitudinal plate 9 with a half-circular structure can be fixed at the bottom end of the hanging rod 8. The two longitudinal plates 9 are provided with insertion holes on the opposite side walls, and a crossbeam 10 that passes through the through hole in the outer wall of the pile body is inserted between the two insertion holes. As shown in Figure 8, after the cone sleeves 6 connected by the two L-shaped handles 7 are placed in the pile body, the two longitudinal plates 9 below the ends of the two L-shaped handles 7 are located at the top of the outer wall of the pile body, and the insertion holes of the longitudinal plates 9 are aligned with the through holes of the preset guardrail installation of the pile body, and then the crossbeam 10 is passed through the insertion holes and the through holes of the pile body to form an external lifting component on the outside of the pile body, which is more conducive to assisting in pulling out the pile body.

[0032] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
