Description

Technical Field

[0001] This utility model belongs to the field of anchor static pressure pile technology, and specifically relates to a connection structure for anchor static pressure piles. Background Technology

[0002] In construction engineering, anchor static pressure piles are a commonly used method for foundation reinforcement. During the construction of anchor static pressure piles, due to the limitations of the construction site or materials, when the pile length is insufficient, it is necessary to align and splice the piles. Welding is usually used to connect the two piles.

[0003] When splicing existing anchor static pressure piles, the lack of positioning between the upper and lower piles can easily lead to pile misalignment, affecting the quality of the splicing. Auxiliary connection structures are needed to ensure accurate connection. Although some auxiliary structures on the market can guarantee accurate connection, they still need to be removed after the connection before the pile body is welded, which affects construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a connection structure for anchored static pressure piles to solve the problems existing in the background art.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a connection structure for a static pressure anchor pile, comprising a base, wherein the base is annular, the base is provided with a lifting mechanism, and the upper part of the lifting mechanism is provided with a positioning mechanism;

[0006] The lifting mechanism includes a rotating ring, which is rotatably mounted on the upper end of the base. The upper end of the rotating ring is provided with a mounting ring, and the lower end of the mounting ring is fixedly mounted with a lifting ring. The lifting ring extends into the interior of the base. The surface of the lifting ring is provided with threads and is threadedly connected to the rotating ring. The lifting mechanism is used to adjust the height of the mounting ring and the positioning mechanism so that the positioning mechanism can complete the positioning work.

[0007] The positioning mechanism includes a positioning ring, which is rotatably mounted on the upper end of the mounting ring. The upper side of the positioning ring has an outward oblique opening, and the lower side of the positioning ring has a welding groove. The positioning mechanism is used to align the upper pile body with the lower pile body when connecting the piles. The welding groove is used to weld the upper and lower pile bodies without removing the structure.

[0008] The positioning ring is equipped with a slag removal mechanism, which includes a slag removal block. The vertical sidewall of the welding groove is provided with a slag removal groove, and the slag removal block is installed in the slag removal groove. The slag removal mechanism is used to clean the welding slag generated after welding.

[0009] The slag-knocking groove is rotatably mounted with a screw, which is threadedly connected to the slag-knocking block. The screw rotates through the positioning ring, and a rotating block is fixedly mounted at the end of the screw. The threaded connection between the screw and the slag-knocking block is designed to adjust the position of the slag-knocking block, making the slag-knocking operation more flexible and convenient.

[0010] A handle is fixedly installed on the outside of the positioning ring, which is used to improve the ease of rotating the positioning ring.

[0011] A limiting groove is provided on the lower inner wall of the base, and a limiting block matching the limiting groove is fixedly installed on the lower outer wall of the lifting ring. The limiting groove and the limiting block are used to limit the lifting ring so that it can only move up and down, preventing the lifting ring from rotating with the rotating ring and making the lifting process more stable.

[0012] Several rotating rods are fixedly installed on the outer wall of the rotating ring, and the rotating rods are used to improve the convenience of rotating the rotating ring.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up the lifting mechanism and the positioning mechanism, the positioning mechanism is moved upward by the lifting mechanism. The inclined opening design on the upper side of the positioning ring will gradually squeeze the upper pile body towards the center of the positioning ring during the movement. Since the base is sleeved on the outside of the lower pile body, the alignment of the upper and lower pile bodies is completed.

[0015] 2. By opening welding grooves on the positioning ring, welding of the upper and lower piles can be carried out without removing the connection structure, which simplifies the welding operation process, saves construction time, and improves construction efficiency. Furthermore, without removing the structure, the upper and lower piles can be continuously aligned and supported, preventing the upper and lower piles from shifting during the welding process, and further improving the welding quality.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-5 As shown, a connection structure for a static pressure anchor pile includes a base 100, which is annular and equipped with a lifting mechanism. The upper part of the lifting mechanism is equipped with a positioning mechanism. The inner diameter of the base 100 should match the outer diameter of the pile to be driven, and a gap with an error range can be left to ensure the sliding of the pile with the structure.

[0025] The lifting mechanism includes a rotating ring 101, which is rotatably mounted on the upper end of the base 100. The upper end of the rotating ring 101 is provided with a mounting ring 102, and the lower end of the mounting ring 102 is fixedly mounted with a lifting ring 103. The lifting ring 103 extends into the interior of the base 100. The surface of the lifting ring 103 is threaded and threadedly connected to the rotating ring 102. By setting up the lifting mechanism, the height of the mounting ring 102 and the positioning mechanism can be adjusted, so that the positioning mechanism can complete the positioning work.

[0026] The positioning mechanism includes a positioning ring 104, which is rotatably mounted on the upper end of the mounting ring 102. The upper side of the positioning ring 104 has an outward-facing oblique opening, and the lower side of the positioning ring 104 has a welding groove 105. By setting up the positioning mechanism, the upper pile body and the lower pile body are aligned during pile splicing. By setting up the welding groove 105, welding of the upper and lower pile bodies is allowed without removing this structure, which simplifies the welding operation process, saves construction time, and improves construction efficiency. Furthermore, without removing this structure, the upper and lower pile bodies can be continuously aligned and supported, preventing the upper and lower pile bodies from shifting during the welding process, and further improving the welding quality.

[0027] Furthermore, the positioning ring 104 is equipped with a slag removal mechanism, which includes a slag removal block 201. The vertical sidewall of the welding groove 105 is provided with a slag removal groove 202, and the slag removal block 201 is installed in the slag removal groove 202. The head and rear of the slag removal block 201 are elastically rotatably connected to simulate a knocking method to improve the slag removal effect. By setting up the slag removal mechanism, the welding slag generated after welding can be cleaned.

[0028] Furthermore, a screw 203 is rotatably installed in the slag-knocking groove 202. The screw 203 is threadedly connected to the slag-knocking block 201. The screw 201 rotates through the positioning ring 104. A rotating block 204 is fixedly installed at the end of the screw 201. Through the threaded connection design between the screw 201 and the slag-knocking block 201, the position of the slag-knocking block 201 can be adjusted, making the slag-knocking work more flexible and convenient.

[0029] Furthermore, a handle 301 is fixedly installed on the outer side of the positioning ring 104, thereby improving the ease of rotating the positioning ring 104.

[0030] Furthermore, a limiting groove 302 is provided on the lower inner wall of the base 100, and a limiting block 303 matching the limiting groove 302 is fixedly installed on the lower outer wall of the lifting ring 103. By setting the limiting groove 302 and the limiting block 303, the lifting ring 103 is limited so that it can only move up and down, preventing the lifting ring 103 from rotating with the rotating ring 101, and making the lifting process more stable.

[0031] Furthermore, a number of rotating rods 304 are fixedly installed on the outer wall of the rotating ring 101. By setting the rotating rods 304, the convenience of rotating the rotating ring 101 is improved.

[0032] The usage of this embodiment is as follows: The structure is fitted onto the lower pile body. After the base 100 is installed, the upper pile body is placed on top of the lower pile body. The operator rotates the rotating ring 101 via the rotating rod 304. The rotating ring 101 drives the lifting ring 103, the mounting ring 104, and the positioning mechanism to move upwards. During the movement, due to the oblique opening design at the top of the positioning ring 104, the positioning ring 104 gradually squeezes the upper pile body towards the center of the positioning ring 104 to complete the alignment of the upper and lower pile bodies. The rotating ring 101 is then rotated to align the welding groove 105 with the joint between the upper and lower pile bodies. The operator can then perform welding from the welding groove 105. After welding the gap in the welding groove 105, the remaining positions can be welded by gripping the positioning ring with the handle 301.

[0033] In this embodiment, by setting up the lifting mechanism and the positioning mechanism, the lifting mechanism moves the positioning mechanism upward. The inclined opening design on the upper side of the positioning ring 104 gradually squeezes the upper pile towards the center of the positioning ring 104 during the movement. Since the base 100 is sleeved on the outside of the lower pile, the alignment of the upper and lower piles is completed. By opening a welding groove 105 on the positioning ring 104, welding of the upper and lower piles is allowed without removing this connection structure, which simplifies the welding operation process, saves construction time, and improves construction efficiency. Furthermore, without removing this structure, the upper and lower piles can be continuously aligned and supported, preventing the upper and lower piles from shifting during the welding process, and further improving the welding quality.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
